可重新封闭的袋子和用于其中的滑块中的可重新封闭的通道Reclosable bags and reclosable channels in sliders for use in them

技术领域technical field

本发明涉及一般的容器领域，更具体地涉及多用途、专业储存袋。This invention relates to the field of containers in general, and more particularly to multipurpose, professional storage bags.

背景技术Background technique

袋子通常被用作并被人们看做方便的、多用途的、重量轻的及低成本的容器。具有可重新封闭的开口的袋子是有用的，因为它为其中的内容物和为储存目的提供了更佳的安全性。这样的袋子还具有的优点是，更好地保护珍贵的或者敏感的内容物，或者选择地，保护环境免受有毒或者有害的内容物的污染。Bags are generally used and regarded as convenient, versatile, lightweight and low cost containers. A bag with a reclosable opening is useful as it provides better security for the contents therein and for storage purposes. Such bags also have the advantage of better protecting precious or sensitive contents, or alternatively, protecting the environment from toxic or harmful contents.

一种普通的可封闭的袋子的结构具有沿着三个边连接在一起的塑料膜制成的两个矩形基片，在一边通常在顶部留有开口。通过在两个相对的基片上形成联锁条，例如，通过舌片及槽部分，可重新封闭的开口或者拉链被设置在开口侧。通过将各个基片压合在一起，可以方便地闭合所述的袋子，于是所述舌片咬合在所述槽内，并且通过将基片拉开来打开。A common closable bag construction has two rectangular base sheets of plastic film joined together along three sides, on one side usually leaving an opening at the top. A reclosable opening or zipper is provided on the opening side by forming interlocking strips on two opposing substrates, for example, through tongue and groove portions. The bag is conveniently closed by pressing the individual substrates together, whereupon the tabs snap into the slots, and are opened by pulling the substrates apart.

在某些情况下，添加滑块来促进袋子的打开和封闭。滑块是单独的、通常模制的塑料件，它安装在基片上并且围绕基片的边形成袋子的开口，于是它能够沿着所述条滑动。滑块通常制造为，施加向内的压合力来促进相对的平面连接或者联锁，而且包括跨过袋子开口的分离器或者指状物。通过这种结构，封闭所述袋子需要在封闭方向推动滑块，而打开袋子需要沿着相反的、打开方向移动所述滑块。In some cases, sliders were added to facilitate opening and closing of bags. The slider is a separate, usually molded piece of plastic that is mounted on the substrate and forms the pocket opening around the sides of the substrate so that it can slide along the strip. Sliders are typically manufactured to apply an inward compression force to facilitate opposing planar connection or interlocking, and include separators or fingers across the opening of the bag. With this arrangement, closing the bag requires pushing the slider in the closing direction, while opening the bag requires moving the slider in the opposite, opening direction.

在许多应用中，比如食物、液体或者生物废品的储存，希望封闭的袋子形成气密的或者防漏的密封。然而，对于具有滑块的袋子，滑块的分离器或者指状物部分通常跨过开口，这防碍了气密密封的形成。在一个试图改进的方案中，Blythe的美国专利US6,526,632具有一个滑块，其通过在闭合端向上旋转滑块来将分离部件提离袋子的开口。然而该装置比传统的滑块更复杂，这增加了成本，而且明显地依赖于专用的配对紧固件12。In many applications, such as food, liquid or biological waste storage, it is desirable for the closed bag to form an airtight or leak-proof seal. However, for bags with sliders, the separator or finger portion of the slider typically spans the opening, which prevents the formation of an airtight seal. In an attempted improvement, US Pat. No. 6,526,632 to Blythe has a slider that lifts the separation member away from the opening of the bag by rotating the slider upward at the closed end. However, the device is more complex than conventional sliders, which adds to the cost, and relies significantly on adedicated mating fastener 12 .

另一个希望的特征，特别是对于珍贵的内容物来说，是从封闭的袋子内部清除剩余空气的能力。家庭储存袋的使用者的通常做法是，比如，首先几乎自始至尾地封闭袋子，只留出小部分的开口。然后，挤压袋子以通过小的开口放出剩余的空气，之后使用者试图快速地在空气重新进入袋子之前封闭小开口。然而这种不规则的方法通常是不方便的，并且产生不稳定的效果。它还是笨拙的，特别对于运动技巧差的个人。Another desirable feature, especially for precious contents, is the ability to remove residual air from the inside of the closed bag. A common practice among users of home storage bags is, for example, to first close the bag almost all the way, leaving only a small opening. The bag is then squeezed to release the remaining air through the small opening, after which the user attempts to quickly close the small opening before air re-enters the bag. However, this irregular approach is often inconvenient and produces erratic effects. It is also clumsy, especially for individuals with poor motor skills.

已经做出了一些试图改进的方案，以构造具有清除空气用的内置设施的可封闭袋子。例如，Minica的专利US6045264展示了一种袋子，其具有的顶部开口被分为主开口和更小的抽空开口。后者的开口构造为包括一个吸管，用于清除剩余的内部空气。Strong的专利US5839582展示了一种袋子，具有带吸入口和单向阀的弓形泵室。当封闭袋子时，所述泵室能够被压缩以通过所述单向阀挤出空气。Herrington的专利US4532652展示了一种粘着在孔内的延伸部分，所述孔在膜做侧边的一个基片中。挤压袋子引起延伸部分从所述侧边基片分离，使得空气溢出所述孔。之后，延伸部分返回到它覆盖孔的位置，防止内部空气的进一步流出。Several attempts have been made to construct closable bags with built-in means for removing air. For example, Minica patent US6045264 shows a bag with a top opening divided into a main opening and a smaller evacuation opening. The opening of the latter is constructed to include a straw for removing the remaining internal air. Strong's patent US5839582 shows a bag having an arcuate pump chamber with a suction inlet and a one-way valve. When the bag is closed, the pump chamber can be compressed to force air through the one-way valve. Herrington's US 4,532,652 shows an extension that is adhered in the hole in a substrate on the side of the membrane. Squeezing the bag causes the extensions to separate from the side substrates, allowing air to escape the holes. Afterwards, the extension returns to its position covering the hole, preventing further escape of the air inside.

所有的这些装置要求改变标准的储存袋，这增加了成本。另外，所示的袋子没有使用滑块，这可能是由于带滑块的气密密封的成形有困难。All of these arrangements require changes to the standard storage bag, which adds to the cost. Also, the bag shown does not use sliders, which may be due to difficulties in forming an airtight seal with sliders.

发明内容Contents of the invention

所需要的是一种能克服一个或多个与现有袋子相关的问题的可重新封闭的袋子。What is needed is a reclosable bag that overcomes one or more of the problems associated with prior bags.

优选地，袋子应当是对使用者容易的、方便封闭的。具体地，如果使用滑块来构造袋子是优选地，所述滑块有利于更强的气密密封以及打开和封闭。强的气密密封更好地维持珍贵内容物的新鲜，及更好地防止有毒内容物污染环境。将袋子构造为这样的也是优选的，即在封闭袋子后，使用者能够方便地清除袋子内部的剩余空气，气体或者流体，或者可选择地，没有干扰气密密封而用气体或流体填满内部。Preferably, the bag should be easy, convenient closure for the user. In particular, it is preferred if the bag is constructed using sliders, which facilitate a stronger airtight seal and opening and closing. A strong airtight seal better maintains the freshness of precious contents and better prevents toxic contents from contaminating the environment. It is also preferred that the bag be constructed such that, after closing the bag, the user can easily purge the bag interior of any remaining air, gas or fluid, or alternatively, fill the interior with gas or fluid without disturbing the airtight seal .

为了保持低成本，袋子优选地通过传统的生产技术，使用标准材料和元件进行制造。袋子优选地适合于作为普通用途的储存袋或者作为饮料和其它物品用的商业容器进行生产。另一个优选特征是，对于袋子的可封闭开口特征为可更换的。由此，不是通常的结构即滑块的一侧打开袋子而另一侧封闭袋子，而是例如制造袋子的开口为，当移动滑块时在滑块的任一侧保持封闭。这种特征使得生产的可封闭袋子具有更大的灵活性，其更密切地适合不同场合的需要。也优选的是，袋子有效地保留液体，而且具有防止不经意间泄漏的特征。To keep costs low, the bags are preferably manufactured by conventional production techniques using standard materials and components. The bag is preferably suitable for production as a general purpose storage bag or as a commercial container for beverages and other items. Another preferred feature is that the closable opening feature to the bag is replaceable. Thus, instead of the usual construction where one side of the slider opens the bag and the other side closes the bag, for example the opening of the bag is made to remain closed on either side of the slider when the slider is moved. This feature allows greater flexibility in the production of closable bags which are more closely adapted to the needs of different occasions. It is also preferred that the bag effectively retains liquid and has features that prevent inadvertent leakage.

因此，本发明提供了一种可重新封闭的袋子，包括：Accordingly, the present invention provides a reclosable bag comprising:

(a)限定了袋子内部和袋子开口的袋子部分；(a) the portion of the bag that defines the interior of the bag and the opening of the bag;

(b)用于打开和封闭所述袋子开口的装置，所述装置包括：(b) means for opening and closing said bag opening, said means comprising:

(ii)在所述袋子开口内介于相对的联锁结构之间的滑块，当所述滑块移动时，所述联锁结构啮合/分离，所述滑块还被构造为当安置在所述袋子开口的一端时密封所述袋子开口；(ii) a slider within said bag opening between opposing interlocking formations that engage/disengage said interlocking formations when said slider is moved, said slider being further configured to when placed in sealing the bag opening at one end of the bag opening;

(c)在所述滑块内的通道，提供了所述袋子内部和所述袋子的外部区域之间的通路；和(c) a channel within the slider providing access between the interior of the bag and the exterior region of the bag; and

(d)用于选择地打开和封闭所述通道的装置；(d) means for selectively opening and closing said passage;

其中，当移动所述滑块到袋子开口的所述端并密封袋子开口时，所述袋子内部和袋子的所述外部区域之间通过所述通道可选择地提供通路。Wherein, passage is selectively provided between the interior of the bag and the outer region of the bag through the channel when moving the slider to the end of the bag opening and sealing the bag opening.

具体实施方式Detailed ways

在图1中示出的是本发明的可封闭袋子，通常用参照序号10表示。其中袋子部分12限定袋子内部14。该袋子部分除了袋子开口16外通常沿着它的边被密封或者封闭，而该开口限定了可选择打开或者封闭的未密封部分。在图1中，袋子开口16是介于端部22和端部24之间的袋子的顶部未密封边。Illustrated in FIG. 1 is the closable bag of the present invention, generally indicated by thereference numeral 10 . Wherein thebag portion 12 defines abag interior 14 . The bag portion is normally sealed or closed along its sides except for thebag opening 16 which defines an unsealed portion which can be selectively opened or closed. In FIG. 1 ,bag opening 16 is the top unsealed edge of the bag betweenend 22 andend 24 .

所述可封闭袋子包括用于选择性地打开和封闭袋子开口的装置。所述用于打开和封闭的装置通常包括两个元件-沿着袋子开口16的位置相对的联锁结构18，和滑块20。所述滑块20位于袋子开口16内，介于相对的联锁结构18之间，并且通常沿着至少它们长度的一部分是可以移动的。所述滑块20还具有这样的结构，即当它移动时，引起它所经过的相对的联锁结构18的一部分啮合或者分离。The sealable bag includes means for selectively opening and closing the bag opening. The means for opening and closing generally comprise two elements - aninterlocking structure 18 positioned opposite along theopening 16 of the bag, and aslide 20 . Thesliders 20 are located within thebag opening 16 between opposing interlockingstructures 18 and are generally movable along at least a portion of their length. Theslider 20 is also configured to cause engagement or disengagement of a portion of the opposinginterlock formation 18 it passes as it moves.

在图1中，所示的滑块20位于袋子开口16的端部22和端部24之间的中间位置。在该位置，相对的联锁结构18被啮合成为袋子开口16的介于端部22和滑块20之间的封闭部分15，而分离的结构成为袋子开口16的介于滑块20和端部24之间的开口部分17。在图2中，可封闭的袋子10具有可一直滑动到端部24的滑块20。可以看出在该位置，相对的联锁结构18沿着袋子开口16的从端部22至端部24的完整长度彼此啮合。可以观察出，在滑块20的这个位置，封闭的部分15处于最大长度。In FIG. 1 ,slider 20 is shown in an intermediate position betweenend 22 and end 24 ofbag opening 16 . In this position, the opposing interlockingstructure 18 is engaged as theclosure portion 15 of thebag opening 16 between theend 22 and theslider 20 and the disengaged structure becomes theclosure portion 15 of thebag opening 16 between theslider 20 and the end. 24 betweenopenings 17 . In FIG. 2 , theclosable bag 10 has aslider 20 that can slide all the way to theend 24 . It can be seen that in this position, the opposinginterlock formations 18 engage each other along the entire length of the bag opening 16 fromend 22 to end 24 . It can be seen that in this position of theslider 20 the closedportion 15 is at its maximum length.

可封闭的袋子10这样构成，即当滑块处在图2所示的位置时，其中联锁结构18被完全啮合而且袋子开口16完全封闭，袋子10通常被气密密封。本发明还包括一个通道26，以提供袋子内部14和袋子的外部区域28之间的入口，还包括用于选择性地打开和封闭所述通道的装置。在图1中，显示的通道26位于滑块20内。当袋子的开口16被完全封闭而且袋子10也气密密封时，通过所述通道26，本发明的袋子能够相应选择性地提供袋子内部14和外部区域28之间的入口。Theclosable bag 10 is constructed such that when the slider is in the position shown in FIG. 2, wherein theinterlocks 18 are fully engaged and thebag opening 16 is fully closed, thebag 10 is generally hermetically sealed. The present invention also includes achannel 26 to provide access between thebag interior 14 and thebag exterior region 28, and means for selectively opening and closing said channel. In FIG. 1 ,channel 26 is shown withinslider 20 . By way of saidchannel 26 the bag according to the invention is able to selectively provide access between thebag interior 14 and theexterior region 28 when thebag opening 16 is completely closed and thebag 10 is also hermetically sealed.

本发明的袋子部分12包含任何具有容器或者袋子功能的结构。更具体地，袋子部分12限定袋子内部14，该内部是袋子内部能够容纳各种用于存放的内容物的空间。Thebag portion 12 of the present invention encompasses any structure that functions as a container or bag. More specifically,bag portion 12 defines abag interior 14, which is a space within the bag capable of containing various contents for storage.

袋子开口16代表一定区域或者空间，借此可以获得进入袋子内部14的入口。根据应用场合，袋子内容物可以通过袋子开口16进行存放或者重新收回。袋子开口16优选地通过用于构成袋子部分12的材料的未密封或者未连接缝来形成，但是也可以在所述材料的表面上通过切口、裂缝、断口、间隙、孔或者其它任何位置的断裂来形成。袋子开口16的位置因此可以沿着袋子材料的两片或者更多片的边、分界面或者缝，或者沿着所述材料的顶部、底部、侧边、对角线或者其它部分。Thebag opening 16 represents an area or space whereby access to thebag interior 14 can be obtained. Depending on the application, the bag contents can be stored or retrieved through thebag opening 16 . Thebag opening 16 is preferably formed by an unsealed or unconnected seam of the material used to make up thebag portion 12, but may also be formed by a cut, crack, break, gap, hole or break at any other location in the surface of said material. to form. The location of thebag opening 16 may thus be along an edge, interface or seam of two or more pieces of bag material, or along a top, bottom, side, diagonal or other portion of the material.

如图1优选实施例所示的，通过沿着四个边中的三个边连接材料的两个矩形基片来形成简单的袋子部分12。可选择地，图1的实施例也可以通过折叠单张材料形成两个基片并且密封两个侧边来制造。为了便于参照，两个基片用前基片30和后基片32进行表示。在该实施例中，袋子内部14是两个基片30和32之间的空间体积，而袋子开口16是通过所述两个基片在袋子未密封顶边上的边在其周长上包围而成的区域。As shown in the preferred embodiment of Figure 1, thesimple bag portion 12 is formed by joining two rectangular substrates of material along three of the four sides. Alternatively, the embodiment of Figure 1 can also be manufactured by folding a single sheet of material to form two base sheets and sealing the two sides. For ease of reference, the two substrates are indicated byfront substrate 30 andrear substrate 32 . In this embodiment, thebag interior 14 is the volume of space between the twosubstrates 30 and 32, while thebag opening 16 is surrounded on its perimeter by the edges of the two substrates on the unsealed top edge of the bag. formed area.

袋子部分12也优选地包括在袋子外部上靠近袋子开口16的支撑件33。所述支撑件33例如可以采用脊、凸耳(ledge)、加厚(bulge)或者类似突起。在图1的袋子中，支撑件33是袋子材料沿着袋子每个基片中顶部开口侧的边缘的增厚或者加厚部分。如下面将详细讨论的，支撑件33提供促进滑块20的支撑或者附着的表面。Thebag portion 12 also preferably includes asupport 33 on the bag exterior adjacent thebag opening 16 . The supports 33 may for example take the form of ridges, ledges, bulges or similar protrusions. In the bag of Figure 1, thesupport 33 is a thickened or thickened portion of the bag material along the edge of the top open side in each base sheet of the bag. As will be discussed in detail below, supports 33 provide surfaces that facilitate support or attachment ofslider 20 .

应当观察出，袋子部分12的其它实施例也是可能的，只要它们限定能够容纳内容物的袋子内部14，而且袋子开口16设置到袋子内部的入口。一些可选择的实施例包括由单片没有基片或者缝的球形材料形成的袋子部分12，如图12所示，或者更复杂的具有六个基片的装有角撑板的袋子，如图13所示。在这些实施例中，袋子开口16可以由形成袋子部分12的材料内的断口或者切口来形成。It should be observed that other embodiments of thebag portion 12 are possible as long as they define abag interior 14 capable of containing the contents and thebag opening 16 is provided for access to the bag interior. Some alternative embodiments include abag portion 12 formed from a single piece of spherical material with no bases or seams, as shown in FIG. 12, or a more complex gusseted bag with six bases, as shown in FIG. 13. In these embodiments,bag opening 16 may be formed by a break or cut in the material formingbag portion 12 .

袋子部分12优选地由这样的材料制成，即具有足够的密度以无泄漏地容纳空气、气体、液体或者其它流体内容物，而且具有足够的强度以没有撕裂地容纳所希望的内容物。所述材料优选地应当为抗水材料，以与液体接触时没有损失结构强度。出于这些原因，人们发现由塑料或者聚乙烯制造的袋子足以满足要求了。根据应用，其它材料比如薄膜、叠层或者涂覆纸或说隔离纸也可以具有适当的效果。所述袋子材料优选地是平滑的，但是也可以是制成叠层的。所述叠层有时优选地，特别是在大袋子中，因为它们提供了袋子内部14内的气流运动用的通道。Bag portion 12 is preferably made of a material of sufficient density to contain air, gas, liquid or other fluid contents without leaks and sufficient strength to contain the desired contents without tearing. The material should preferably be water resistant so as not to lose structural strength in contact with liquids. For these reasons, bags made of plastic or polyethylene have been found to suffice. Depending on the application, other materials such as films, laminates or coated or release papers may also be suitable. The bag material is preferably smooth, but may also be laminated. Said laminates are sometimes preferred, especially in large bags, because they provide channels for air movement within thebag interior 14 .

为了保持袋子的柔软特性，所述材料也应当优选地为柔韧的或者有弹性的。材料的柔软程度能够按照应用进行改变。然而，优选地，具有至少足够的柔软性，于是袋子部分12中限定了袋子开口16周长的那一部分可以被使用者拉或拽在一起，以有效地封闭袋子开口16。In order to maintain the soft nature of the bag, the material should also preferably be flexible or elastic. The degree of softness of the material can vary depending on the application. Preferably, however, there is at least enough flexibility so that the portion ofbag portion 12 that defines the perimeter ofbag opening 16 can be pulled or drawn together by a user to effectivelyclose bag opening 16 .

本发明的袋子10通常具有这样的结构，以封闭或者密封它任一处的表面以及除了袋子开口16之外的所有缝和边，其中袋子开口16可以有选择地进行打开或者封闭。因此，封闭袋子开口16具有完全包围内部14和封闭袋子10的效果。袋子10可以替换性地标明为“可封闭的”或者“可重新封闭的”，在每一种情况都意味着袋子可以被重新打开或者封闭。Thebag 10 of the present invention is generally constructed to close or seal any of its surfaces and all seams and sides except for thebag opening 16, which can be selectively opened or closed. Thus, closing thebag opening 16 has the effect of completely surrounding the interior 14 and closing thebag 10 .Bag 10 may alternatively be labeled "closable" or "reclosable," meaning in each case that the bag can be re-opened or closed.

在图1中，袋子开口16形成在相对的基片30和32的未密封侧边的顶边之间的空间内。联锁结构18安装在相对基片30和32的内部部分上，所述内部部分形成袋子开口16的周长。联锁结构18可以更具体地参照前基片30(图1中看不到)的前部件34和后基片32上的联锁部件或后部件36。所述联锁结构18布置成彼此相对，而且其尺寸和形状能够在将基片30和32集合在一起时啮合及封闭袋子开口16。In FIG. 1,pocket opening 16 is formed in the space between the top edges of the unsealed sides of opposingsubstrates 30 and 32. In FIG.Interlocking structure 18 is mounted on the interior portions of opposingsubstrates 30 and 32 that form the perimeter ofbag opening 16 . The interlockingstructure 18 may be more specifically referred to as afront part 34 of the front substrate 30 (not visible in FIG. 1 ) and an interlocking orrear part 36 on therear substrate 32 . The interlockingstructures 18 are disposed opposite each other and are sized and shaped to engage and close thebag opening 16 when thesubstrates 30 and 32 are brought together.

在图1的优选实施例中，联锁结构18的位置位于基片30和32的内部顶边处。该位置是最佳的，因为它使袋子10的内部空间14最大。然而，可以认识到，可以将联锁结构18安置在袋子10上的任何位置，并在任何方向定位，只要它构成尺寸和形状相对的一对，在被啮合时封闭袋子开口16。In the preferred embodiment of FIG. 1 , the location of the interlockingstructure 18 is at the inner top edges of thesubstrates 30 and 32 . This location is optimal because it maximizes theinterior volume 14 of thebag 10 . However, it will be appreciated that interlockingstructure 18 may be positioned anywhere onbag 10 and oriented in any orientation so long as it forms a pair of opposite size and shape that closesbag opening 16 when engaged.

联锁结构18代表任何这样的结构，即当所述基片集合在一起或者使其相互靠近时，能够使袋子部分12的相对基片啮合以封闭袋子开口16，而且还包括任何这样的结构，即当所述基片被拉开或者推开时，能够使啮合的基片分离以重新打开袋子开口16。联锁结构18在设计和成分上最好足够坚固，以在袋子10的期望寿命内能够重复打开和封闭，而没有经历啮合部分的强度上的不当损失。另外，联锁结构的尺寸和形状最好在被啮合时能够形成密封。由此，例如袋子内部14的流体成份不会通过啮合后的联锁结构流出袋子。Interlocking structure 18 represents any structure that enables opposing substrates ofbag portion 12 to engage to closebag opening 16 when said substrates are brought together or brought into close proximity, and also includes any such structure, That is, when the substrates are pulled or pushed apart, the engaged substrates can be separated to reopen thebag opening 16 . The interlockingstructure 18 is preferably sufficiently robust in design and composition to enable repeated opening and closing over the expected life of thebag 10 without experiencing an undue loss of strength in the engaging portions. Additionally, the interlock structures are preferably sized and shaped to form a seal when engaged. Thus, for example, fluid components of thebag interior 14 cannot flow out of the bag through the engaged interlocks.

联锁结构18的优选类型包括各个机械元件，这些元件通过干涉配合或者搭扣配合，比如通过在其它特征内滑动、压缩或者嵌入(snap)的一个特征，可以联锁。这样的布置通常被称为“舌榫”或者“凸凹”(male and female)结构，具有为舌形或者凸形部分的内部件和为槽或凹入部分的外部件。图3表示联锁结构18的优选实施例的横截面视图。在图3a中，具有凸形或舌形特征34和凹形或槽特征36。在该图中，相对的联锁结构没有连接在一起或者啮合在一起，于是袋子开口16是打开的。在图3b中，特征34和36被啮合，于是舌形特征34通过搭扣配合被插进槽特征36内。所述特征34和36优选地由和基片30及32一样的塑料材料制成，并且其大小与形状可以使舌形34紧密配合在槽36内。紧密配合与材料的弹性的组合使得啮合的对构成有效的密封，并抵抗分离，除非向相对的基片30和32施加最小的足够的力来将它们拉开。可以认识到，舌形特征34相对于槽特征36越大，使这些特征搭扣配合会越难，但是连接会更强，密封会更紧密。A preferred type of interlockingstructure 18 includes mechanical elements that can be interlocked by an interference fit or a snap fit, such as by one feature sliding, compressing, or snapping within other features. Such an arrangement is often referred to as a "tongue-and-groove" or "male and female" configuration, with an inner part that is a tongue or male part and an outer part that is a groove or female part. FIG. 3 shows a cross-sectional view of a preferred embodiment of theinterlock structure 18 . In Fig. 3a, there are male or tongue features 34 and female or groove features 36. In FIG. In this figure, the opposing interlocks are not connected together or engaged together so that thebag opening 16 is open. In Fig. 3b, features 34 and 36 are engaged so thattongue feature 34 is inserted intoslot feature 36 with a snap fit. Thefeatures 34 and 36 are preferably made of the same plastic material as thesubstrates 30 and 32 and are sized and shaped so that thetongue 34 fits snugly within thegroove 36 . The combination of the snug fit and the resiliency of the material enables the engaged pair to form an effective seal and resist separation unless a minimal amount of force is applied to the opposingsubstrates 30 and 32 to pull them apart. It will be appreciated that the larger the tongue features 34 relative to the groove features 36, the more difficult it will be to snap fit these features, but the stronger the connection and the tighter the seal.

已经发现图3所示的优选布置通常是适当的，特别是对于低成本的应用，因为它具有适当的使用性能而且可低成本地进行制造。然而，可以认识到，联锁结构18的其它类型也包含在本发明内，只要它们保留不需太大困难地能够啮合或分离的特性，维持啮合的最小足够使用的强度，并且在重复打开和封闭之后保持这种啮合的强度。其它可能的实施例可以包括，例如啮合或者分离相对的基片的磁性装置。The preferred arrangement shown in Figure 3 has been found to be generally suitable, especially for low cost applications, as it has suitable performance properties and can be manufactured at low cost. However, it can be appreciated that other types of interlockingstructures 18 are also encompassed by the present invention, as long as they retain the characteristic of being able to engage or disengage without great difficulty, maintain a minimum strength sufficient for use in the engagement, and remain engaged after repeated opening and closing. The strength of this engagement is maintained after closure. Other possible embodiments may include, for example, magnetic means that engage or disengage opposing substrates.

滑块20优选地为独立的件或者与袋子部分12分离的元件。图5-9表示滑块20的优选实施例的各个视图，为了提高清晰度，独立的滑块元件被单独示出，或者没有连接到袋子部分12。Slider 20 is preferably a separate piece or element separate frombag portion 12 . 5-9 show various views of a preferred embodiment of theslider 20, with individual slider elements shown alone, or not connected to thebag portion 12, for improved clarity.

参照图5，滑块20通常包括在任一侧上具有突出手柄40的中心或者核心体38。所述核心体38具有顶部42，底部44，和一对侧边或侧表面46，为了清晰起见，侧表面还区分为侧表面45和侧表面47。侧表面46包括滑块20中面向或者与袋子12的相对的联锁结构18接触的部分。Referring to FIG. 5 ,slider 20 generally includes a center or core 38 with protruding handles 40 on either side. The core 38 has a top 42, a bottom 44, and a pair of sides or surfaces 46, which for clarity are also distinguished as side surfaces 45 and 47. The side surface 46 includes the portion of theslider 20 that faces or contacts the opposinginterlock structure 18 of thebag 12 .

通过图5中隐藏的视图可以看到，核心体38在中心最宽，而且向着相对的顶部、端部或者边48，50逐渐变细。每一个边48和50的长度从核心体38的顶部42延伸到底部44。滑块20也优选地具有这样的尺寸和形状，即与袋子开口一端的形状互补，以使滑块形成最佳密封。由于该优选结构的结果，在俯视图中体38象扁平的椭圆，在每一端处的一点终止。该滑块20的这种特征也可以在图1和图2中看到，其中以隐藏线(虚线)表示基片30和32在袋子开口16内的上边，该上边包围滑块20的椭圆形核心体38。As can be seen from hidden view in FIG. 5, the core body 38 is widest at the center and tapers toward opposing tops, ends orsides 48,50. The length of eachside 48 and 50 extends from the top 42 to the bottom 44 of the core body 38 . Theslider 20 is also preferably sized and shaped to complement the shape of the open end of the bag so that the slider forms an optimum seal. As a result of this preferred construction, the body 38 resembles a flattened ellipse in plan view, terminating at a point at each end. This feature of theslider 20 can also be seen in FIGS. 1 and 2, where the upper sides of thesubstrates 30 and 32 within thepocket opening 16, which surround the oval shape of theslider 20, are shown in hidden lines (dotted lines). core body38.

手柄40提供保持滑块20在袋子12的适当位置或者附着在袋子12的支撑，而且还为使用者提供在移动滑块时供抓握的手柄、把手或者触点。手柄40优选地附着到滑块体38或者从顶部42或其附近处的滑块体38延伸，并且向外延伸到任一侧及朝着底部44向下延伸一些。对于手柄的底部也优选地朝着体38向内延伸，以产生支撑凸缘52。在图5中，手柄40包括向外的面板53，向下的面板54和向内的面板55。然而可以认识到，比如从单个的弯曲面板形成的手柄40也是足够使用的。在另一个实施例中，提供了更多的表面积，手柄40在向外和向下翻转之前可以竖直升起到滑块体的顶部42的上方。The handle 40 provides support to keep theslider 20 in place or attached to thebag 12, and also provides a handle, grip, or touch point for the user to grasp when moving the slider. The handle 40 is preferably attached to the slider body 38 or extends from the slider body 38 at or near the top 42 and extends outward to either side and some downward toward the bottom 44 . It is also preferred for the bottom of the handle to extend inwardly towards the body 38 to create a support flange 52 . In FIG. 5 , the handle 40 includes an outward facing panel 53 , a downward facing panel 54 and an inward facing panel 55 . It will be appreciated, however, that a handle 40 formed, for example, from a single curved panel will also suffice. In another embodiment, providing more surface area, the handle 40 can be raised vertically above the top 42 of the slider body before flipping out and down.

可以认识到，手柄40包括面向滑块的侧面46的内部部分和面对滑块的侧面而远离该侧面的外部部分。所述外部部分具有可被使用者抓握以抓住或者移动滑块20的表面。因此，手柄40，特别是手柄40的外部部分具有的尺寸和形状优选地提供舒适而安全的抓握表面。例如这可包括在所述表面内的刻痕或者带有结节的橡胶材料的使用，以提供更有效的抓握。It will be appreciated that the handle 40 includes an inner portion facing the side 46 of the slider and an outer portion facing away from the side of the slider. The outer portion has a surface that can be gripped by a user to grasp or move theslider 20 . Accordingly, the handle 40, and particularly the outer portion of the handle 40, preferably has a size and shape that provides a comfortable and secure gripping surface. For example this may include scoring in the surface or the use of a nodulated rubber material to provide a more effective grip.

手柄40的尺寸和形状也优选为这样的，于是所述内部部分通常与滑块的侧面46的轮廓相仿。在图5的优选实施例中，手柄40的内部部分相应地与核心体38的椭圆轮廓相仿，其从端部48和50朝着核心体的中心向外延伸。正如图中所示的，手柄40和它们的内部部分一直朝着滑块体38的端部48延伸，但是在靠近端部50处停止。对于这种结构的原因涉及由端部48和50充当的不同功能，并且在下面更详细地讨论。The size and shape of the handle 40 is also preferably such that the inner portion generally follows the contour of the side 46 of the slider. In the preferred embodiment of Fig. 5, the inner portion of the handle 40 correspondingly follows the elliptical contour of the core 38, which extends outwardly from theends 48 and 50 towards the center of the core. As shown, the handles 40 and their inner portions extend all the way toward theend 48 of the slider body 38 but stop near theend 50 . The reason for this configuration relates to the different functions served byends 48 and 50, and is discussed in more detail below.

滑块20也优选地具有这样的结构，滑块体38的侧面46与手柄40的内部部分的分隔或者间隙距离大约是袋子部分12的单个基片30和32沿着袋子开口16的厚度。更优选地，所述分隔或者间隙距离将比袋子基片的厚度更大，于是存在足够的空间用于袋子的基片插进并装配在滑块体38和手柄40之间，同时保持封闭和可靠的连接。Theslider 20 is also preferably constructed such that the separation or gap distance between the sides 46 of the slider body 38 and the interior portion of the handle 40 is approximately the thickness of theindividual substrates 30 and 32 of thebag portion 12 along thebag opening 16 . More preferably, the separation or gap distance will be greater than the thickness of the bag substrate so that there is enough room for the bag substrate to be inserted and fitted between the slider body 38 and the handle 40 while remaining closed and secure. reliable connection.

图7和8提供了滑块20的侧表面46的放大视图。为更清晰起见，在这些图中，手柄40只是画出轮廓，于是可以更清晰地看到滑块体38和侧面46。可以看到，每一个单独的侧表面45和47具有侧轨56，或者更具体地具有侧表面45上单独侧轨58和侧表面47上的侧轨60。所述侧轨56的尺寸和形状可以与袋子部分12上的相对的联锁结构18配合或者可滑动地啮合，并且因此优选地构造为舌或者槽。从图7a和图8b中可以看到，侧轨58包括舌形或者凸连接件，从图7b和8a可以看到，侧轨60包括槽或者凹连接件。7 and 8 provide enlarged views of the side surface 46 of theslider 20 . For greater clarity, the handle 40 is only outlined in these figures so that the slider body 38 and sides 46 can be seen more clearly. It can be seen that eachindividual side surface 45 and 47 has a side rail 56 , or more specifically anindividual side rail 58 onside surface 45 andside rail 60 onside surface 47 . The side rails 56 are sized and shaped to cooperatively or slidably engage opposinginterlock formations 18 on thebag portion 12, and are therefore preferably configured as tongues or grooves. As can be seen in Figures 7a and 8b, theside rail 58 comprises a tongue or male connector, and it can be seen from Figures 7b and 8a that theside rail 60 comprises a groove or female connector.

侧轨56优选地布置在体38的中间，距离顶部42和底部44的距离相同。侧轨56也优选地通过在侧面46内雕刻所希望的特征，无论舌形还是槽，来形成，于是侧面46保持扁平或者齐平的轮廓。Side rail 56 is preferably disposed in the middle of body 38 at the same distance from top 42 and bottom 44 . The side rails 56 are also preferably formed by carving the desired feature, whether tongue or groove, into the side 46 so that the side 46 maintains a flat or flush profile.

侧轨56通常延伸侧面46的长度，但是依照附近的端部48或50而在结构上有变化。在图7中端部或者凸缘50被突出显示，图7a提供了侧面45和舌形侧轨58的透视图，图7b提供了侧面47和槽侧轨60的透视图，图7c提供了两个侧面和侧轨的前视图。可以看到，侧轨56刚好在凸缘50前面终止，而且没有相互作用，邻接或者其它的彼此接触。凸缘50实际上分隔所述侧轨56，因此从滑块体38的顶部42到底部44保持通常连续的、没有断开的线。The side rails 56 generally extend the length of the sides 46 , but vary in configuration depending on which end 48 or 50 is nearby. End orflange 50 is highlighted in Figure 7, Figure 7a provides a perspective view ofside 45 andtongue side rail 58, Figure 7b provides a perspective view ofside 47 andgroove side rail 60, Figure 7c provides two Front view of two sides and side rails. It can be seen that the side rails 56 terminate just in front of theflange 50 and do not interact, abut or otherwise contact each other. Theflange 50 actually separates the side rails 56 so that a generally continuous, unbroken line is maintained from the top 42 to the bottom 44 of the slider body 38 .

类似地，端部或者凸缘48在图8中被突出显示，图8a提供了侧面47和槽侧轨60的透视图，图8b了提供了侧面45和舌形侧轨58的透视图，图8c提供了两个侧面和侧轨的前视图。在这种情况下，侧轨56在它们沿着边缘48相遇的地方相互作用，产生中空的外部分62。Similarly, end orflange 48 is highlighted in Figure 8, Figure 8a provides a perspective view ofside 47 andgroove side rail 60, Figure 8b provides a perspective view ofside 45 andtongue side rail 58, Figure 8c provides a front view of both sides and side rails. In this case, the side rails 56 interact where they meet along theedge 48 , creating a hollowouter portion 62 .

提供图9来提高边缘48的结构的清晰度。在图9a中，画出了槽侧轨60，但是为了说明的目的，侧面45留有空白，没有画出侧轨58。可以看到，槽60一直延伸到边缘48并将其围绕起来，于是该槽雕刻出侧面45的一小部分。类似地，在图9b中，画出舌形侧轨58，侧面47留有空白。在这种情况下，舌形58也一直延伸并将其围绕，于是延伸进侧面47。当图9的两个侧轨重合时，结果是出现了在图8的各个视图中画出的沿着边缘48的中空部分62。FIG. 9 is provided to improve the clarity of the structure ofedge 48 . In Figure 9a, the trough side rails 60 are shown, but for illustration purposes, thesides 45 are left blank and the side rails 58 are not shown. It can be seen that thegroove 60 extends all the way to theedge 48 and surrounds it, so that the groove engraves a small portion of theside 45 . Similarly, in Figure 9b, the tongue-shapedside rail 58 is drawn, leaving theside 47 blank. In this case, thetongue 58 also extends all the way around and around it, thus extending into theside 47 . When the two side rails of FIG. 9 coincide, the result is thehollow portion 62 drawn along theedge 48 in the various views of FIG. 8 .

图6是滑块体38沿着侧面47的侧视图或者剖面图，画出了槽侧轨60。可以看到边缘50保持连续而没有断开，因为侧轨60和侧轨58(没有画出)都刚好在该边缘的前面终止。与此对照，侧轨60一直延伸到边缘48并将其围绕，沿着侧轨58(没有画出)产生中空部分62。如下面将更详细说明的，各个侧轨在边缘50的结构具有分离相对的联锁结构18的效果，同时在边缘48处的结构啮合联锁结构18。为此，可以交替地指示滑块端部打开或分离边缘50和封闭或联合边缘48。FIG. 6 is a side view or cross-sectional view of slider body 38 alongside 47 , illustratingslot side rail 60 . It can be seen thatedge 50 remains continuous rather than broken, as bothside rail 60 and side rail 58 (not shown) terminate just in front of the edge. In contrast, theside rail 60 extends all the way to and around theedge 48, creating ahollow portion 62 along the side rail 58 (not shown). As will be explained in greater detail below, the formation of each side rail atedge 50 has the effect of separating the opposinginterlock formation 18 while the formation atedge 48 engages theinterlock formation 18 . To this end, the slider end opening or separatingedge 50 and closing or joiningedge 48 can be indicated alternately.

可以使开口边缘50来形成直的垂直边。然而，如图6和图7a和7b所示，边缘50优选地构造为包括沿着它的长度于一处或者多处的突起或者突出部分64。该突出部分64的尺寸和形状可使滑块20与袋子开口16的端部形成更紧密、更互补地配合。通过这种方式，当将滑块移动到袋子开口16的一个端部时，会产生更有效的密封，如图2所示。The openingedge 50 can be made to form a straight vertical edge. However, as shown in Figure 6 and Figures 7a and 7b, theedge 50 is preferably configured to include protrusions or protrusions 64 at one or more locations along its length. The protrusion 64 is sized and shaped to allow theslider 20 to form a tighter, more complementary fit with the end of thebag opening 16 . In this way, when the slider is moved to one end of thebag opening 16, a more effective seal is created, as shown in FIG.

滑块20也优选地包括通道26，该通道是沿着滑块的整个高度从顶部42延伸到底部44的小孔或者孔洞。图5表示带有通道26的以虚线画出的隐藏部分的滑块。所述通道具有任何横截面形状，比如圆形，椭圆形，或者矩形，但是优选为圆形。Theslider 20 also preferably includes achannel 26, which is a small hole or hole extending from the top 42 to the bottom 44 along the entire height of the slider. FIG. 5 shows a slider withchannels 26 drawn in dashed hidden parts. The channels have any cross-sectional shape, such as circular, oval, or rectangular, but are preferably circular.

滑块20优选地由聚乙烯或者塑料材料制成。塑料是优选的，因为它相对坚固，重量轻，抗水，成本低。塑料还有一个优点是，能够相对容易地将它制造为如滑块20这样的复杂形状。例如这可以如此实现，即通过注射成型的标准生产工艺，使用设计的标准模具以符合滑块20的形状。当袋子部分12是塑料时，塑料也是优选的滑块材料，于是能够容易地制成各种部件。可以认识到，本发明也包括其它材料，只要它们拥有一些或者所有的上述特性。用于滑块的其它材料可以包括例如金属，合金，或者木头。Theslider 20 is preferably made of polyethylene or plastic material. Plastic is preferred because it is relatively strong, lightweight, water resistant, and low cost. Plastic also has the advantage that it can be manufactured into complex shapes such asslider 20 with relative ease. This can be achieved, for example, by the standard production process of injection molding, using a standard mold designed to conform to the shape of theslider 20 . When thebag portion 12 is plastic, plastic is also the preferred slider material so that the various components can be easily fabricated. It will be appreciated that other materials are also encompassed by the present invention so long as they possess some or all of the above properties. Other materials for the slider may include, for example, metal, alloy, or wood.

在形成本发明的袋子10时，滑块20的核心体38被安置在袋子开口16内，于是将侧面46安置在前部件34和后部件36的相对表面之间。如图4的截面视图所示，滑块20从袋子的内外两部分附在袋子部分12上。在袋子内部上，滑块的侧轨56与袋子部分12的相对的联锁结构18配合或者可滑动地啮合。就图4的实施例而言，前部件34的舌搭扣在或者装配在侧轨58的槽内，而且侧轨60的舌搭扣或者装配在后部件36的槽内。可以认识到，这些相互作用的元件的其它实施例也是可能的，只要滑块与袋子部分12可滑动地啮合。例如，能够使联锁结构18与袋子部分12齐平，使侧轨58和60从滑块的侧面向外突出。In forming thebag 10 of the present invention, the core 38 of theslider 20 is positioned within thebag opening 16 , thus positioning the sides 46 between the facing surfaces of thefront piece 34 and theback piece 36 . As shown in the cross-sectional view of Figure 4,sliders 20 are attached tobag portion 12 from both the inside and outside of the bag. On the interior of the bag, the side rails 56 of the slider cooperate or slidably engage with opposinginterlock structures 18 of thebag portion 12 . For the embodiment of FIG. 4 , the tongue of thefront part 34 fits or fits in the groove of theside rail 58 and the tongue of theside rail 60 fits or fits in the groove of therear part 36 . It will be appreciated that other embodiments of these interacting elements are possible so long as the slider is slidably engaged with thebag portion 12 . For example, it is possible to have theinterlock structure 18 flush with thebag portion 12 and have the side rails 58 and 60 protrude outwardly from the sides of the slider.

在袋子的外部上，可以看到滑块的手柄40的大小和形状被制造为符合或者紧贴地配合袋子部分12的外支撑件33。具体地，手柄40包围支撑件33，于是支撑件33的底部停留在手柄40的支撑凸缘52上。可以认识到，这些元件的其它实施例也是可能的，只要手柄具有将滑块固定到袋子部分12的外部的装置。例如，支撑件33和手柄40的具体形状可以变化，只要它们连续彼此适应以构成封闭且紧贴的配合。类似地，除了机械配合之外的其它类型的附加连接也是可能的，例如手柄40的内部与袋子部分12或支撑件33的相对的外边之间的磁性连接。On the outside of the bag, it can be seen that the handle 40 of the slider is sized and shaped to conform or snugly fit theouter support 33 of thebag portion 12 . In particular, the handle 40 surrounds thesupport 33 so that the bottom of thesupport 33 rests on the support flange 52 of the handle 40 . It will be appreciated that other embodiments of these elements are possible as long as the handle has a means of securing the slider to the exterior of thebag portion 12 . For example, the specific shape of thesupport 33 and the handle 40 may vary so long as they continuously adapt to each other to form a closed and snug fit. Similarly, other types of additional connections than mechanical fits are possible, such as a magnetic connection between the interior of the handle 40 and the opposite outer edge of thebag portion 12 orsupport 33 .

可以认识到，袋子内联锁元件与手柄围绕外部支撑件33的紧密配合的组合使滑块20紧密地固定在袋子部分12上。具体地，这样附加连接滑块20，即它不能落入袋子内部14或者无意中从顶部开口冒出来。如果没有坚决有力的作用，滑块20将抵抗最大的试图使其从袋子部分12分离或卸下的尝试。It will be appreciated that the combination of the interlocking elements inside the bag and the tight fit of the handle around theouter support 33 secures theslider 20 to thebag portion 12 tightly. Specifically, theslider 20 is additionally attached in such a way that it cannot fall into thebag interior 14 or pop out of the top opening inadvertently. Without firm and forceful action,slider 20 will resist the most vigorous attempts to separate or remove it frombag portion 12 .

当沿着袋子开口16移动滑块时，滑块20具有的大小和形状能与联锁结构18啮合，或者选择地，与联锁结构18分离。更具体地，滑块20的边48和50的结构决定了袋子开口16的给定部分在滑块在具体方向移动时是否会啮合或者分离。Slider 20 is sized and shaped to engage or, alternatively, disengage frominterlock structure 18 as the slider is moved alongbag opening 16 . More specifically, the configuration ofsides 48 and 50 ofslider 20 determines whether a given portion ofbag opening 16 will engage or disengage when the slider is moved in a particular direction.

返回到图1所示的可封闭袋子10的优选实施例，可以看到，从中间位置可以在两个方向，即朝着任一端部22或者端部34，移动滑块20。在沿其中任一方向移动滑动时，滑块边48或50中的一个将面向移动方向的那个端部，而且另一边将面向相反的一端进行拖拉。本发明的袋子10被构造成使得滑块可以沿着袋子开口16的一部分移动，在被滑块移动所覆盖的该部分内的联锁结构18依照滑块20的拖拉端或边的特性进行连接或啮合，或者选择地，分开或分离。Returning to the preferred embodiment of theclosable bag 10 shown in FIG. 1 , it can be seen that from the intermediate position theslider 20 can be moved in two directions, namely towards either end 22 orend 34 . When moving the slide in either direction, one of the slider sides 48 or 50 will face that end in the direction of movement, and the other side will face the opposite end to pull. Thebag 10 of the present invention is configured such that the slider can move along a portion of thebag opening 16, the interlockingstructure 18 in the portion covered by the movement of the slider being connected according to the nature of the trailing end or edge of theslider 20. Either engage, or alternatively, disengage or disengage.

更具体地，在图1中，滑块20被定向为使得连接边48面向袋子10的端部22或袋子开口16的封闭部分15，而且分离边50面向袋子的端部24或袋子开口16的开口部分17。当朝着端部24移动滑块20时，联锁结构18将根据拖拉与连接边48进行连接，封闭，啮合或者联锁。由此，封闭部分15将在长度上增加，而开口部分17在长度上同等大小地减少。如图2所示，当滑块到达端部24时，联锁结构18的整个长度将被封闭。类似地，当滑块20朝着端部22移动时，例如当从图2的位置移动到图1的位置时，联锁结构18将依照拖动与分离边50进行分开，打开或者分离。More specifically, in FIG. 1 , theslider 20 is oriented so that the connectingedge 48 faces theend 22 of thebag 10 or theclosure portion 15 of thebag opening 16, and the separatingedge 50 faces theend 24 of the bag or the closingportion 15 of thebag opening 16. Openingpart 17. When theslider 20 is moved towards theend 24, the interlockingstructure 18 will connect, close, engage or interlock with the connectingedge 48 according to the drag. Thus, theclosed portion 15 will increase in length, while theopen portion 17 will decrease in length by an equal amount. As shown in FIG. 2, when the slider reaches theend 24, the entire length of theinterlock structure 18 will be closed. Similarly, when theslider 20 is moved towards theend 22, for example when moving from the position of FIG. 2 to the position of FIG. 1, the interlockingstructure 18 will separate, open or disengage from theseparation edge 50 according to the drag.

滑块20的连接和分离功能可以通过拖拉联锁结构18贯穿滑块20的边48和80的路径来理解。如图4所示，联锁结构在滑块侧面46的大部分长度上与侧轨56进行啮合。当图1的滑块朝着端部24移动时，联锁结构中经过拖拉边48的部分将由于侧轨的连续而被拽到一起，刚好到边48并围绕着边48。当每一个侧轨围绕处于边48的相对侧面时，将迫使可滑动地啮合的舌与槽特征部件34和36进行接触，使舌34搭扣或者压缩进槽36内。此外，手柄40的内部直到边48一直与侧面46的轮廓一致。因为手柄40的内部与侧面46之间的间隙或者分隔距离非常小，而且优选地只有边缘处的厚度大于单个基片30和32的上边的厚度，所以迫使基片30和32停留在侧轨56的轨道内并迫使它们贴合在一起。由此，联锁结构18从与滑块的侧轨46可滑动地啮合，如图1所示的65和66，到彼此联锁在一起，如图2中它们在封闭部分15上的对应位置，进行平滑过渡。The connecting and disconnecting functions of theslider 20 can be understood by dragging the path of theinterlock 18 through thesides 48 and 80 of theslider 20 . As shown in FIG. 4 , the interlock engages the side rail 56 over most of the length of the slider side 46 . As the slider of FIG. 1 moves towardend 24, the portions of the interlock that pass trailingedge 48 will be drawn together due to the continuation of the side rails, just to and aroundedge 48. As each side rail surrounds opposite sides ofedge 48 , the slidably engaged tongue and groove features 34 and 36 are forced into contact, causingtongue 34 to snap or compress intogroove 36 . Furthermore, the inside of the handle 40 follows the contour of the side 46 up to theedge 48 . Because the gap or separation distance between the interior of the handle 40 and the side 46 is very small, and preferably only the edge is thicker than the upper edge of theindividual substrates 30 and 32, thesubstrates 30 and 32 are forced to rest on the side rails 56. track and force them to fit together. Thus, the interlockingstructures 18 go from being slidably engaged with the side rails 46 of the slider, as shown at 65 and 66 in FIG. , for a smooth transition.

相反，当滑块朝着端部22移动时，因为分离边50在任一侧的侧轨56上的终止，相反特征的部件34和36中经过拖拉边50的部分将不能啮合。此外，手柄40的内部只与侧面46的轮廓一致，一直到尚未达到分离边50的一点处。对于手柄40的内部，没有必要一直延伸，因为在分离边50处不要求将联锁结构压缩在一起。结果，当相反特征的部件34和36随着滑块20的轮廓朝向边缘50逐渐变窄而彼此靠近时，由于它们从侧轨56脱落，它们将保持分开，因为在滑块侧轨上没有引导或轨迹或者没有来自手柄40的外部压力来将它们保持在一起。Conversely, as the slider moves towardend 22, the portions ofmembers 34 and 36 of opposite characteristics past trailingedge 50 will not engage because of the termination of separatingedge 50 on side rail 56 on either side. Furthermore, the interior of the handle 40 only conforms to the contour of the side 46 up to a point where the separatingedge 50 is not yet reached. For the interior of the handle 40, it is not necessary to extend all the way, as there is no requirement at the separatingedge 50 to compress the interlocking structure together. As a result, as theparts 34 and 36 of opposite character approach each other as the profile of theslider 20 tapers towards theedge 50, they will remain separated due to their falling off the side rail 56 because there is no guide on the slider side rail. or track or no external pressure from the handle 40 to keep them together.

可以认识到，可封闭袋子10的其它打开/封闭特征能够通过改进滑块20的结构来实现。例如，不是具有连接边48和分离边50，可使滑块20具有两个连接边48。在这种情况下，袋子开口16会在滑块的两个侧面上于滑块的任一位置在希望的长度内保持封闭。可选择地，如果滑块被构造成具有两个分离边50，袋子开口16没有一部分会封闭。It will be appreciated that other opening/closing features of theclosable bag 10 can be achieved by modifying the structure of theslider 20 . For example, instead of having a connectingedge 48 and a separatingedge 50 , theslider 20 could have two connectingedges 48 . In this case, thebag opening 16 will remain closed for the desired length at any position of the slider on both sides of the slider. Alternatively, if the slider is configured with two separatingsides 50, no portion of thebag opening 16 will be closed.

当袋子开口16被完全封闭时，可封闭袋子10具有的结构能够在袋子14内产生气密密封。如图2所示，在将滑块20移动到端部24处的密封位置时发生这种密封。Closable bag 10 is constructed to create an airtight seal withinbag 14 whenbag opening 16 is fully closed. This sealing occurs when theslider 20 is moved into the sealed position at theend 24 as shown in FIG. 2 .

本发明的联锁结构优选地具有这样的尺寸和形状，即当被啮合时能够形成密封。具体地，舌形特征部件34和槽特征部件36优选具有这样的尺寸和形状，即当它们联锁或者搭扣配合在一起时形成气密密封。因此，随着滑块在图2所示的位置，袋子开口16从端部22到滑块的端部48的封闭部分15将由于联锁结构18的啮合而气密密封。The interlocks of the present invention are preferably sized and shaped to form a seal when engaged. In particular,tongue feature 34 andgroove feature 36 are preferably sized and shaped to form an airtight seal when they interlock or snap fit together. Thus, with the slider in the position shown in FIG. 2 , theclosed portion 15 of the bag opening 16 from theend 22 to the slider'send 48 will be hermetically sealed due to the engagement of theinterlock structure 18 .

当被安置在所述袋子开口一端时，滑块20具有的结构能够密封袋子开口16。滑块20因此优选具有的结构能够围绕它的周边产生密封。在封闭部分15遇到连接边48的点处，由于来自紧密配合的手柄的向内压力以及与侧轨56的连接，联锁结构18被紧密挤压在一起。由此，在联锁结构18和滑块的界面处保持气密密封。由于侧轨56和联锁结构18之间的搭扣配合，沿着滑块的侧面46，维持气密密封。因此，侧轨56优选具有的尺寸和形状能够与联锁结构18产生气密配合或气密啮合。在袋子10的分离边50和端部24的界面处，通过构造滑块20特别是分离边50实现气密密封，于是这弥补了袋子开口16在端部24的形状。在袋子10的优选实施例中，滑块的边50具有“V”形状，这弥补并且紧密地配合袋子开口16在端部24处的类似“V”形状。分离边50优选地还包括突起或者突出部分64。如图6的侧视图所示，这个特征在于通过从滑块突出保持气密密封，以填充在袋子开口16于端部24处可能存在的导致漏气的任何递增空间。Slider 20 is configured to sealbag opening 16 when positioned at the bag opening end.Slider 20 therefore preferably has a structure capable of creating a seal around its periphery. At the point where theclosure portion 15 meets the connectingedge 48 , the interlockingstructures 18 are squeezed together due to the inward pressure from the tightly fitting handles and connection to the side rails 56 . Thus, an airtight seal is maintained at the interface of theinterlock 18 and the slider. Along the sides 46 of the slider, an airtight seal is maintained due to the snap fit between the side rails 56 and theinterlock structure 18 . Accordingly, the side rails 56 are preferably sized and shaped to create an airtight fit or engagement with theinterlock structure 18 . At the interface of the separatingedge 50 and theend 24 of thebag 10 , an airtight seal is achieved by configuring theslider 20 , in particular the separatingedge 50 , which then compensates for the shape of thebag opening 16 at theend 24 . In the preferred embodiment of thebag 10, theside 50 of the slider has a "V" shape which complements and closely fits the similar "V" shape of thebag opening 16 at theend 24 . The separatingedge 50 preferably also includes a protrusion or protrusion 64 . As shown in the side view of FIG. 6 , this feature maintains an airtight seal by protruding from the slider to fill any incremental space that may exist at theend 24 of thebag opening 16 leading to air leaks.

可以认识到，滑块20和袋子部分12的其它形状也可以使用，只要滑块顶端和袋子开口16端部的形状足够互补以形成紧密而贴合的配合。也可以认识到，本发明是如何对现有技术进行改进的。在过去使用的滑块通常包括分离或者撬开所述基片的分离器或者手指。所述分离器通常构造为满足这种功能，而且不会与袋子开口形成互补配合。这样的滑块通常不能在普通的移动中密封袋子开口，因为分离器阻止滑块完全封闭袋子开口。It will be appreciated that other shapes of theslider 20 andbag portion 12 may be used as long as the shapes of the top end of the slider and the end of thebag opening 16 are sufficiently complementary to form a snug, snug fit. It will also be appreciated how the present invention improves upon the prior art. Sliders used in the past typically included separators or fingers that detach or pry apart the substrate. The separators are generally configured to fulfill this function and do not form a complementary fit with the opening of the bag. Such sliders generally cannot seal the bag opening during ordinary movement because the separator prevents the slider from completely closing the bag opening.

当滑块到达端部24时，为了保持密封，优选的是安置一个插销或者其它装置将滑块20固定在位，并且防止它后退。这在本发明中通过一个制动器(detent)来实现，该制动器是锁定一部分滑块的运动的插销或者杆。制动器可以安置在沿着滑块20或者袋子部分12的任一位置。To maintain the seal when the slider reachesend 24, it is preferable to provide a latch or other means to hold theslider 20 in place and prevent it from backing up. This is accomplished in the present invention by a detent, which is a pin or lever that locks a portion of the slide's movement. The detent may be positioned anywhere along theslider 20 orbag portion 12 .

在图1的优选实施例中，袋子部分12包含第一制动器68，滑块20包含在手柄40内侧上的第二制动器70。当滑块移动到密封位置时，第一制动器68和第二制动器70的结构能够彼此啮合。第一制动器68优选地为位于袋子部分12的外表面上，比如在外部支撑件33上的凸块或者升高的结节。第二制动器70优选地为位于手柄40内侧的凹槽。当滑块20移动到密封位置时，制动器68搭扣进制动器70或者与其啮合。该实现的连接优选足够地强以将滑块20固定就位，同时当需要重新打开袋子时，能够由使用者向端部22推动滑块而不需太大困难。In the preferred embodiment of FIG. 1 , thebag portion 12 includes afirst stop 68 and theslider 20 includes asecond stop 70 on the inside of the handle 40 . Thefirst detent 68 and thesecond detent 70 are configured to engage each other when the slider is moved to the sealing position. Thefirst detent 68 is preferably a bump or raised nodule on the outer surface of thebag portion 12 , such as on theouter support 33 . Thesecond detent 70 is preferably a groove located inside the handle 40 . Thedetent 68 snaps into or engages thedetent 70 when theslider 20 is moved to the sealing position. The resulting connection is preferably strong enough to hold theslider 20 in place while being able to be pushed by the user towards theend 22 without undue difficulty when the bag needs to be reopened.

可以认识到，能够锁住滑块的其它实施例也是可能的，只要防止滑块20后退并且保持良好密封。例如，图10表示具有设置在滑块顶部42上的垂耳72的滑块20。在图10所示的密封位置，垂耳可以被移动，旋转，或者进行其它定位，以与袋子部分12的外边上的制动器(没有画出)做搭扣配合。当需要移动滑块时，向上翻转垂耳72并且使它不挡道，以恢复滑块的移动性。It will be appreciated that other embodiments that lock the slider are possible as long as theslider 20 is prevented from backing off and a good seal is maintained. For example, FIG. 10 shows aslider 20 havinglugs 72 disposed on the top 42 of the slider. In the sealed position shown in FIG. 10 , the tab can be moved, rotated, or otherwise positioned to snap fit with detents (not shown) on the outer edge ofbag portion 12 . When the slider needs to be moved, thelug 72 is flipped up and out of the way to restore slider mobility.

通道26的结构能够提供袋子内部14和外部区域28之间的入口，无论袋子开口16是否被打开或者封闭。在本发明的优选实施例中，通道26优选地在滑块20内部或者与滑块20成为一体。因为滑块被设置在联锁结构18之间，可以认识到袋子内部14和外部区域28之间通过通道26的入口不会受到影响，即使袋子开口16被气密地封闭并密封。Thechannel 26 is configured to provide access between thebag interior 14 and theexterior region 28 regardless of whether thebag opening 16 is open or closed. In a preferred embodiment of the invention, thechannel 26 is preferably inside or integral with theslider 20 . Because the slider is positioned between theinterlocks 18, it will be appreciated that access between thebag interior 14 and theexterior region 28 through thechannel 26 will not be affected even if thebag opening 16 is hermetically closed and sealed.

通道26的大小和形状能够提供流体通道入口，比如气体或者液体，或者象颗粒或粉末的固体物质。The size and shape of thechannel 26 can provide access to the passage of fluids, such as gases or liquids, or solid substances like granules or powders.

通道26具有的大小和形状还优选地接受流体输送管道74，比如管(pipe)，软管(tube)或者普通的吸管。管74的通常形状显示在图10中。这样的装置当从袋子外部28被连接到所述通道时，允许使用抽吸，例如通过所述通道26来移出袋子内部14的流体。更具体地，具有耦合或插入端76以及自由端78的抽吸装置可以被连接到滑块顶表面42上的通道26。可以在自由端78施加吸力来抽吸袋子内部14的象液体或气体等流体的内容物。在工业性应用中，优选地通过机械真空装置来施加所述抽吸。在日常消费品中，优选地通过使用者的嘴作用在吸管的自由端78来施加抽吸。优选地，流体输送管74可以拆卸，而且通道26相应地具有的尺寸和形状能够与可拆卸的管74进行连接和分离。由此，在从袋子内部14去除流体后，可以方便地取下管74，于是不会和袋子作为储存容器的用途相冲突。Thechannel 26 is also preferably sized and shaped to accept afluid delivery conduit 74, such as a pipe, tube, or common straw. The general shape of thetube 74 is shown in FIG. 10 . Such a device, when connected to the channel from thebag exterior 28 , allows the use of suction, for example through thechannel 26 , to remove fluid from thebag interior 14 . More specifically, a suction device having a coupling or insertion end 76 and afree end 78 may be connected to thechannel 26 on the slider top surface 42 . Suction can be applied at thefree end 78 to suck the contents of thebag interior 14, which is a fluid such as a liquid or gas. In industrial applications, the suction is preferably applied by mechanical vacuum means. In consumer products, the suction is preferably applied by the user's mouth acting on thefree end 78 of the straw. Preferably, thefluid delivery tube 74 is detachable and thechannel 26 is sized and shaped accordingly to enable connection and disconnection of thedetachable tube 74 . Thus, after removal of fluid from thebag interior 14, thetube 74 can be easily removed, thus not interfering with the bag's use as a storage container.

通道26优选地包括用于打开和封闭该通道的装置或者阀80，如图5所示。阀80是任一种能够安置在通道26内的装置或者结构，其具有的尺寸和形状以及结构具有至少一个封闭状态和至少一个打开状态。当阀80处于封闭状态时，会阻塞流过通道26的流体。在这种状态，如果袋子开口16被完全封闭，会气密密封袋子内部14。当阀80处于打开状态时，能够实现进入袋子内部14，或者袋子内部14和袋子外部28之间的流体流动。可以认识到，当阀80处于打开状态并且袋子开口16被完全封闭时，进入袋子内部14的入口只能通过通道26和阀80获得。Channel 26 preferably includes a device or valve 80 for opening and closing the channel, as shown in FIG. 5 . Valve 80 is any device or structure capable of being disposed withinpassage 26 that is sized and shaped and configured to have at least one closed state and at least one open state. Fluid flow throughpassage 26 is blocked when valve 80 is in a closed state. In this state, if thebag opening 16 is fully closed, thebag interior 14 is hermetically sealed. Fluid flow into thebag interior 14, or between thebag interior 14 and thebag exterior 28, is enabled when the valve 80 is in the open state. It will be appreciated that when valve 80 is in the open state andbag opening 16 is fully closed, access tobag interior 14 is only available throughchannel 26 and valve 80 .

阀80优选地为单向阀，意味着当阀处于打开状态时，只允许流体在一个方向流动。例如，单向阀可以构造为允许流体从袋子内部14离开到外部28的流动，而且阻碍流体从外部28流到袋子内部14。例如，这种类型的阀对于清除用过的袋子内的空气以储存食品或者其它珍贵内容物是有用的。可选择地，所述单向阀可以具有这样的结构，即允许只在另一方向即从袋子外部28进入袋子内部14的通路或者流体流动，而且阻碍流体从袋子内部14流到外部28。这种类型的阀对于一种应用是有用的，即需要向袋子内注射保存或者保护袋子内容物的特殊气体或者液体，比如使用甲醛来保存生物标本。Valve 80 is preferably a one-way valve, meaning that when the valve is in the open state, fluid is only allowed to flow in one direction. For example, the one-way valve may be configured to allow the flow of fluid away from thebag interior 14 to the exterior 28 , but to block the flow of fluid from the exterior 28 to thebag interior 14 . For example, this type of valve is useful for purging the air in used bags to store food or other precious contents. Alternatively, the one-way valve may have a structure that allows access or fluid flow in the other direction only, namely from thebag exterior 28 into thebag interior 14 , and blocks fluid flow from thebag interior 14 to theexterior 28 . This type of valve is useful for applications that require the injection of a specific gas or liquid into the bag that preserves or protects the contents of the bag, such as the use of formaldehyde to preserve biological specimens.

本发明的袋子10包括几乎任何一种类型的能通过通道26实现所需流动特性的阀80的应用。例如，阀80可以是双向阀而不是单向阀。双向阀是具有两个打开状态的阀，其中一个状态允许流体在一个方向流动，另一个状态允许在另一个方向流动。具体状态的启动可以简单地从阀的使用获得。例如，挤压袋子10可以促使空气从袋子内部14流出，通过阀80流向袋子外部28。可选择地，可以将所述管连接到具有同一阀的通道26并且施加压力促使流体进入袋子内。在这种状态，所述阀允许流体从与第一应用方向相反的方向即从外部28到袋子内部14流动。可选择地，双向阀80可以具有这样的结构，即流体的允许方向通过阀本身上的或者优选地在滑块20表面上的一个开关进行设定。Bag 10 of the present invention includes the use of virtually any type of valve 80 that can achieve the desired flow characteristics throughchannel 26 . For example, valve 80 could be a two-way valve rather than a one-way valve. A two-way valve is a valve that has two open states, one of which permits fluid flow in one direction and the other permits flow in the other direction. The activation of a specific state can be obtained simply from the use of the valve. For example, squeezing thebag 10 may cause air to flow from thebag interior 14 through the valve 80 to thebag exterior 28 . Alternatively, the tubing can be connected to channel 26 with the same valve and pressure applied to force fluid into the bag. In this state, the valve allows fluid to flow from the direction opposite to the first application direction, ie from the exterior 28 to the interior 14 of the bag. Alternatively, the two-way valve 80 may be of such a construction that the permitted direction of fluid is set by a switch on the valve itself or preferably on the surface of theslider 20 .

所述阀80可以这样构造：当它处于打开状态时，通道26基本上或者完全打开，于是流过通道的流体能够以最高速度流动。可选择地，阀80可以构造成能够部分地封闭通道26到任何希望的程度。The valve 80 may be constructed such that when it is in the open position, thepassage 26 is substantially or fully open so that fluid flowing through the passage can flow at its highest velocity. Alternatively, valve 80 may be configured to partiallyclose passage 26 to any desired extent.

可以认识到，所述阀通常被构造为能够安装在通道内或者安装在位于实心体内的管内。因此，为了安装在本发明的通道26内，许多类型的标准阀是可用的，因为通道26优选地位于滑块20的实心体内。适合应用在本发明的通道26内的一种普通类型的阀是球阀，它通常如图5所示的阀80。当向球阀施加压力时，比如通过管74的抽吸，该球阀会升高并且打开通道26。另一种类型的阀80是夹紧阀(pinching valve)，它通过通道对滑块施加挤压或者夹紧而提供通路。类似地，工业和消费品应用中非常普通的许多其它类型的阀也可以应用在本发明中。除了球阀或者夹紧阀外，阀80例如可以是挡板阀，气阀，或者止回阀。It will be appreciated that the valves are generally configured to fit within a channel or within a tube within a solid body. Therefore, to fit within thechannel 26 of the present invention, many types of standard valves are available, since thechannel 26 is preferably located within the solid body of theslider 20 . One common type of valve suitable for use inpassage 26 of the present invention is a ball valve, which is generally shown as valve 80 in FIG. 5 . When pressure is applied to the ball valve, such as suction throughtube 74 , the ball valve lifts and openspassage 26 . Another type of valve 80 is a pinching valve, which provides passage through a channel that squeezes or pinches the slider. Similarly, many other types of valves that are very common in industrial and consumer applications may find use in the present invention. In addition to a ball valve or a pinch valve, the valve 80 can be, for example, a flapper valve, a gas valve, or a check valve.

本发明包括没有成一体的通道26的滑块20的应用。可以认识到，由于滑块20具有的结构能够打开或者封闭袋子开口16，并且当处于完全封闭位置时形成气密密封，带有滑块20的袋子是有用的，即使没有通道26。例如，袋子10可被填充液体，用封闭的滑块形成气密密封，防止液体的泄漏。当使用液体内容物时，推动滑块而轻微打开，倒出液体。由于滑块20，这样的袋子10具有容易打开和封闭的优点，而且还具有气密密封的好处以更好地保存珍贵的内容物或者容纳液体。The present invention includes the use ofsliders 20 withoutintegral channels 26 . It will be appreciated that a bag withslider 20 is useful even withoutchannel 26 becauseslider 20 has a structure that opens or closesbag opening 16 and forms an airtight seal when in the fully closed position. For example, thebag 10 may be filled with a liquid, with closed sliders forming an airtight seal to prevent leakage of the liquid. When using liquid contents, push the slider to open slightly to pour out the liquid. Such abag 10 has the advantage of being easy to open and close thanks to theslider 20, but also has the benefit of an airtight seal to better preserve precious contents or contain liquids.

本发明还包括将通道26从滑块20分离。这样的布置优选地使用包含或者与通道26成一体的通路元件82来实现。通路元件82是通常布置在袋子10的两个边或者两个基片之间的本体，其包含通道26和阀80。通路元件82具有的尺寸和形状类似于滑块20，或者它具有其它任何的尺寸和形状，只要它能够安置在袋子10的两个边之间。通路元件82优选地固定就位。这例如通过围绕通路元件82的各个边密封基片30和32来实现。The invention also includes separating thechannel 26 from theslider 20 . Such an arrangement is preferably accomplished using apassage element 82 that incorporates or is integral with thechannel 26 . Theaccess element 82 is a body generally disposed between two sides of thebag 10 or two substrates, which contains thechannel 26 and the valve 80 .Access element 82 has a size and shape similar toslider 20 , or it has any other size and shape so long as it fits between the sides ofbag 10 .Access element 82 is preferably fixed in place. This is accomplished, for example, by sealing thesubstrates 30 and 32 around the respective edges of theaccess element 82 .

在一个实施例中，袋子10的两个边可以是限定袋子开口16的相对基片30和32的两个边。在这种情况下，通路元件82的边可以本领域熟知的各种方式被密封在相对基片30和32之间。袋子10还可以做成没有围绕通路元件82的联锁结构18，因为不需要所述结构18支撑滑块在袋子开口16的这部分内的运动。如图11所示的实施例，它表示没有通道26的可移动的滑块20，而且通路元件82具有通道26和可卸下的管或者吸管74。In one embodiment, the two sides of thebag 10 may be the two sides of the opposingsubstrates 30 and 32 that define thebag opening 16 . In this case, the sides of viamember 82 may be sealed between opposingsubstrates 30 and 32 in various ways well known in the art. Thebag 10 can also be made without the interlockingstructure 18 surrounding theaccess member 82 since thestructure 18 is not required to support the movement of the slider within this portion of thebag opening 16 . The embodiment shown in FIG. 11 , which shows themovable slider 20 without thechannel 26 , and theaccess member 82 has thechannel 26 and the removable tube orstraw 74 .

可以认识到，在固定通路元件82的地方，进入袋子内部14的通道26的使用不会受袋子10内通路元件82的具体位置的影响。因此，在又一个实施例中，袋子10的两个边可以是没有限定袋子开口16的相对基片30和32的两个边。这通常包括袋子10的除了被袋子开口16占据的那部分外的周边。在图11中，例如，其中安置有通路元件82的两个边可以是沿着袋子10的封闭边84和86的的基片30和32的边。It will be appreciated that where theaccess member 82 is secured, the use of thechannel 26 into thebag interior 14 is not affected by the particular location of theaccess member 82 within thebag 10 . Thus, in yet another embodiment, the sides of thebag 10 may be sides of the opposingsubstrates 30 and 32 that do not define thebag opening 16 . This generally includes the perimeter of thebag 10 except for that portion occupied by thebag opening 16 . In FIG. 11 , for example, the two sides on whichaccess member 82 is disposed may be the sides ofsubstrates 30 and 32 alongclosed sides 84 and 86 ofbag 10 .

在该实施例中，优选的是，安置在袋子10的相对的基片或者相对的边之间的通路元件82被连接，焊接或者缝合在一起。这样的布置简化了袋子10的制造，因为通路元件82可以被安置在基片之间，而基片包围通路元件。所述基片可以象以前一样被焊接或者缝合在一起，将通路元件82密封在它们之间。在通过折叠连接两个相对的基片的场合，通路元件的安装会由于需要制作出孔而不很方便。例如，如果图11中的袋子10由沿着底边88折叠的单个基片制成，在边88上安装通路元件会不方便。如果袋子由沿着所有的边焊接或者连接在一起的分离的基片30和32制成，那么沿着任一边84，86，88安装通路元件82会一样地方便。In this embodiment, it is preferred that theaccess members 82 disposed between opposing substrates or opposing sides of thebag 10 are joined, welded or stitched together. Such an arrangement simplifies the manufacture of thebag 10 because theaccess element 82 can be positioned between the substrates which surround the access element. The substrates can be welded or stitched together as before, sealing theaccess element 82 between them. Where two opposing substrates are joined by folding, the mounting of the via element can be inconvenient due to the need to make holes. For example, if thebag 10 in FIG. 11 was made from a single substrate folded along thebottom edge 88, it would be inconvenient to install access elements on theedge 88. Installingaccess member 82 along eitherside 84, 86, 88 is just as convenient if the bag is made fromseparate substrates 30 and 32 welded or joined together along all sides.

本发明的优选实施例现在可以理解为其中通路元件82是滑块20的情况。这个实施例是优选的，因为只有一个本体的袋子，包括带有成一体的通道的滑块，比具有两个本体的袋子，包括通路元件和滑块，通常制造和使用成本更低且效率更高。The preferred embodiment of the invention can now be understood as the case where theaccess element 82 is theslider 20 . This embodiment is preferred because bags with only one body, including sliders with integrated channels, are generally less expensive and more efficient to manufacture and use than bags with two bodies, including access elements and sliders. high.

普通类型的袋子的生产涉及沿着三个边或者沿着单个折叠基片的相对边连接两个矩形基片，在一侧留出敞开的袋子开口16。滑块可以在制造过程中被插进袋子开口16，于是沿着袋子开口16，它是可以移动的，而没有从袋子上卸下。标准生产设备也通常以高运转或者高生产速度进行作业，这导致成本降低。Production of a common type of bag involves joining two rectangular substrates along three sides or along opposite sides of a single folded substrate, leaving an open bag opening 16 on one side. The slider can be inserted into thebag opening 16 during manufacture so that it can move along thebag opening 16 without being removed from the bag. Standard production equipment also typically operates at high operating or production speeds, which results in reduced costs.

本发明的袋子10的袋子部分12类似地能由一个或者两个塑料基片沿着两个或者三个边，留出袋子开口16连接而成。沿着袋子开口16的联锁结构18类似地使用标准生产技术进行制造。本发明的滑块20被制造为独立的本体，能够通过标准注射成型技术进行生产。因此，当滑块在形式和功能上不同于现有技术的滑块时，它依旧能够以相似的低成本进行制造。此外，用于生产袋子和安装滑块的标准生产设备能够用于生产本发明的袋子10。在生产中，可移动滑块20将被安置在袋子开口16下方，如果需要的话，在袋子开口16内或者在基片被密封前沿着基片之间的连接或者缝，安装分开的通路元件82。Thebag portion 12 of thebag 10 of the present invention can similarly be formed from one or two plastic substrates joined along two or three sides leaving abag opening 16 . The interlockingstructure 18 along thebag opening 16 is similarly fabricated using standard production techniques. Theslider 20 of the present invention is manufactured as a separate body, capable of being produced by standard injection molding techniques. Thus, while the slider differs in form and function from prior art sliders, it can still be manufactured at a similar low cost. Furthermore, standard production equipment for producing bags and mounting sliders can be used to produce thebags 10 of the present invention. In production, themoveable slider 20 will be positioned below thebag opening 16, if desired, with aseparate access element 82 installed within thebag opening 16 or along the junction or seam between the substrates before the substrates are sealed. .

因此，可以认识到本发明的袋子10可以与不具有本发明其它优点的传统滑块袋子大约一样或者不相上下的低成本进行生产。袋子和滑块的材料成本类似于传统袋子，在只有稍许改进的情况下，生产设备是一样的或者可以使用的。此外，因为可以使用标准生产设备，这种设备的工业标准高运转速度可以继续应用。还可以认识到，这代表对现有技术的改进。因为现有技术中的设备通常需要非传统的袋子和阀，袋子和阀的材料和生产设备都不是标准的，并且需要定制。此外，运转速度可能比较低，这增加了每个袋子的成本。Accordingly, it will be appreciated that thebag 10 of the present invention can be produced at about the same or comparable cost as a conventional slider bag without the other advantages of the present invention. Material costs for bags and sliders are similar to conventional bags, and production equipment is the same or can be used with only minor modifications. Furthermore, since standard production equipment can be used, the industry standard high operating speeds of such equipment can continue to be applied. It will also be appreciated that this represents an improvement over the prior art. Because prior art devices often require non-traditional bags and valves, the materials and production equipment for the bags and valves are not standard and require customization. Additionally, operating speeds may be relatively low, which increases the cost per bag.

现在使用如图10所示的构造为可重新封闭的袋子10的实施例做为家用储存袋，描述本发明的操作。使用者通过将滑块20移动到端部22开始使用，打开袋子开口16。使用者将珍贵的食品90存放在袋子内部14，然后移动滑块20到端部24处的封闭或密封位置来封闭袋子。在如图1和2所示的滑块20使用制动器68和70的情况中，使用者通过感觉或者听到制动器碰击或者搭扣就位来测量将滑块移动到多远，于是在第二端24啮合滑块。可选择地，在如图10所示滑块带有垂耳72的情况中，使用者通过转动垂耳到向下的位置并将其搭在相应位置，将滑块锁就位。The operation of the present invention will now be described using the embodiment of areclosable bag 10 configured as shown in FIG. 10 as a household storage bag. The user initiates use by moving theslider 20 to theend 22 , opening thebag opening 16 . The user deposits theprecious food item 90 in thebag interior 14 and then moves theslider 20 to the closed or sealed position at theend 24 to close the bag. In the case ofslider 20 as shown in Figures 1 and 2 usingdetents 68 and 70, the user measures how far to move the slider by feeling or hearing the detents click or snap into place, then in thesecond End 24 engages the slider. Alternatively, in the case of the slider withlugs 72 as shown in Figure 10, the user locks the slider into place by turning the lugs to the downward position and latching them into place.

在此时，袋子将被气密密封，但是袋子内部14可能包含剩余的空气。然后使用者通过可重新封闭的袋子开口16内的通道26交换袋子内部14与袋子外部28之间的空气或流体。例如，通过将中空管74的插入端76插进通道26内并且向自由端78施加吸力，可以实现袋子内部14的空气或流体的清除。当是消费品时，中空管74优选的为吸管，而且由使用者的嘴施加吸力。在此实施例中的阀80优选为单向阀，允许流体沿从袋子内部14到外部28的方向流动。当袋子内部14的空气全部或者基本全部清除时，管74可以从通道26取出，将袋子10安置在仓库内。在另一实施例中，不是使用中空管74，可以挤压袋子10促使剩余的空气通过通道26逸出袋子内部14。这种方法也可以通过图11所示的具有滑块和通路元件82的At this point, the bag will be hermetically sealed, but thebag interior 14 may contain residual air. The user then exchanges air or fluid between thebag interior 14 and thebag exterior 28 through thechannel 26 in thereclosable bag opening 16 . For example, removal of air or fluid from thebag interior 14 may be accomplished by inserting the insertion end 76 of thehollow tube 74 into thechannel 26 and applying suction to thefree end 78 . When a consumer product,hollow tube 74 is preferably a straw, and suction is applied by the user's mouth. The valve 80 in this embodiment is preferably a one-way valve, allowing fluid to flow in a direction from the interior 14 to theexterior 28 of the bag. When thebag interior 14 is completely or substantially free of air, thetube 74 can be removed from thechannel 26, and thebag 10 can be placed in the warehouse. In another embodiment, instead of using thehollow tube 74 , thebag 10 can be squeezed to force remaining air to escape thebag interior 14 through thechannel 26 . This method can also be achieved by a slider andaccess element 82 as shown in FIG. 11

实施例得到实现。Embodiments are realized.

可以认识到，本发明的封闭袋子的方法体现了对现有技术的改进。现有技术中，使用者通常会移动滑块封闭端部24，留出小的开口17。挤压袋子以促使剩余的空气流出开口17。然后，使用者用一只手封闭滑块，同时保持另一只手压在袋子上，以防止在封闭滑块的过程中流入空气。此外，一旦袋子被封闭，由于袋子开口内的传统滑块的分离器或者手指的存在，不可能形成气密密封。与此对比，在本发明中，使用者能够通过挤压袋子、对中空管74施加吸力，将空气从袋子挤出，或另外一方面，不用关注可能流入的空气，因为阀80会锁住任何流入的空气。因此可以认识到，本发明封闭袋子的方法比传统方法更简单、、更方便，并且还产生了更大的没有空气的袋子内部空间14。It will be appreciated that the method of closing a bag of the present invention represents an improvement over the prior art. In the prior art, the user would normally move theclosed end 24 of the slider, leaving asmall opening 17 . Squeeze the bag to force the remaining air out ofopening 17. The user then closes the slider with one hand while keeping the other hand pressed against the bag to prevent air from entering during the process of closing the slider. Furthermore, once the bag is closed, it is not possible to form an airtight seal due to the separator of a conventional slider or the presence of fingers within the bag opening. In contrast, in the present invention, the user is able to force the air out of the bag by squeezing the bag, applying suction to thehollow tube 74, or otherwise, without concern for possible inflow of air because the valve 80 will lock any incoming air. It can thus be appreciated that the method of closing the bag of the present invention is simpler, more convenient than conventional methods and also produces a largerinterior space 14 of the bag free of air.

在本发明的另一应用中，通道26中安装有阀80，阀80允许流体流进袋子内部14同时阻止相反方向的流动。这样的袋子可以使用在工业装置中接收饮用流体或者其它商售的流体。例如，在内容物为饮用流体时，阀80可以为双向阀，于是使用者可以使用吸管取到内容物。可选择地，图11所示的双本体结构也可以使用，其中滑块20具有带着允许流体在一个方向流动的阀的通道26，而且通路元件82具有带着允许流体在另一方向流动的阀的通道。在这种情况中，使用一个通道填充袋子，使用另一个通道取出或者饮用内容物。对于非饮用类型的流体，推动滑块打开小段距离以允许使用者倒出内容物。In another application of the invention, a valve 80 is installed in thechannel 26 which allows fluid to flow into thebag interior 14 while preventing flow in the opposite direction. Such bags may be used in industrial settings to receive drinking fluids or other commercially available fluids. For example, where the contents are drinking fluids, the valve 80 can be a two-way valve so that the user can use a straw to access the contents. Alternatively, a dual body configuration as shown in FIG. 11 could be used, in which theslider 20 has achannel 26 with a valve allowing fluid to flow in one direction, and thepassage member 82 has a valve with a valve allowing fluid to flow in the other direction. valve channel. In this case, one channel is used to fill the bag and the other channel is used to remove or drink the contents. For non-potable type fluids, pushing the slider opens a small distance to allow the user to pour out the contents.

可以认识到，各种商业袋子的构造借助本发明都是可能制造的。具体地，对于本发明的袋子10的设计者要利用的参数包括：选择边48和50用作滑块的边，无论在它们之间是使用单个的滑块20还是使用带有一个或两个通道的附加通路元件82，选择阀80的类型，以及是否密封联锁结构18的所有部分或者一部分。另外，除了标准的两基片结构外，设计者可选择各种袋子形状。例如，图12和13表示适合用作商业饮料容器的袋子10的示例。图12是圆形容器，图13是具有在任一端上的角撑板(gusset)的矩形容器。所述圆形容器具有便宜的优点，对于要使用的一定量的材料提供最大的内部体积，而且还使运输能力最优化，因为相邻的袋子彼此压缩，只留出非常小的未用空间。It will be appreciated that a variety of commercial bag configurations are possible with the present invention. Specifically, parameters to be utilized by the designer of thebag 10 of the present invention include the selection ofsides 48 and 50 as sides for sliders, whether asingle slider 20 is used between them or with one or two Theadditional access element 82 of the channel, selects the type of valve 80 and whether to seal all or part of theinterlock structure 18 . In addition, designers can choose from a variety of bag shapes in addition to the standard two-substrate configuration. For example, Figures 12 and 13 show an example of abag 10 suitable for use as a commercial beverage container. Figure 12 is a circular container and Figure 13 is a rectangular container with gussets on either end. Said circular container has the advantage of being cheap, provides the largest internal volume for a given amount of material to be used, and also optimizes transport capacity, since adjacent bags are compressed against each other, leaving very little unused space.

还可以使用标准设备来生产袋子部分12，用作图12和13所示的袋子类型。袋子开口16可以由袋子表面上的细缝或切口形成，使用标准设备安装滑块20。在所示的实施例的各种变体中，袋子开口16可以制造得更短，或者袋子开口16的长度被密封得尽可能最长。滑块可以沿着短距离移动，该距离大约等于滑块的长度。在生产中，滑块可以被安置在留出小开口17的位置，在开口17内插进一个喷嘴填充容器。然后将滑块移动较短的距离密封开口，并且在出售之后保持在这个位置。使用时的通路可以通过插进通道26的吸管进入。Standard equipment can also be used to produce thebag portion 12, for the type of bag shown in Figures 12 and 13. Thebag opening 16 may be formed by slits or cuts in the surface of the bag to which theslider 20 is mounted using standard equipment. In variations of the illustrated embodiment, thebag opening 16 can be made shorter, or the length of thebag opening 16 can be sealed as long as possible. The slider can be moved along a short distance approximately equal to the length of the slider. In production, the slider can be placed in a position leaving asmall opening 17 into which a nozzle is inserted to fill the container. The slider is then moved a short distance to seal the opening and remains in this position after sale. Access in use may be through a straw inserted intochannel 26 .

伴随由软性材料制成的或者针对儿童使用的商业饮料包装出现的一个问题是，由于给袋子的侧面施加压力，不经意间会喷出内容物。在图12和13的袋子中，可以认识到，使用的阀80优选地构造为允许流体流出袋子内部14。这样的阀还可构造为保持封闭状态直到压力的预定阈值。例如该压力值可以设定为高于通常由袋子的偶然挤压所引起的压力值。优选地，或者单独根据袋子侧面的一定挤压或者根据这些侧面挤压的组合，可设定压力阈值以满足最低的抽吸水平。由此，能够减少或者避免袋子内容物的不经意间的喷出。此外，所示通道的尺寸可制造为只允许有限的流量以防止液体的突然喷射。One problem that arises with commercial beverage packages made of soft materials or intended for use by children is the inadvertent ejection of the contents due to the pressure applied to the sides of the bag. In the bag of FIGS. 12 and 13 , it will be appreciated that the valve 80 used is preferably configured to allow fluid to flow out of thebag interior 14 . Such valves may also be configured to remain closed up to a predetermined threshold of pressure. For example, the pressure value can be set higher than the pressure value normally caused by accidental squeezing of the bag. Preferably, the pressure threshold can be set to meet the minimum suction level, either solely based on a certain squeeze of the sides of the bag or based on a combination of these side squeezes. Thereby, inadvertent ejection of the bag contents can be reduced or avoided. Furthermore, the passages shown may be sized to allow only a limited flow to prevent sudden ejection of liquid.

在另一个实施例中，使袋子10带有具有两个连接边48的滑块。然后，总是在滑块20的两边封闭袋子开口16。在又一变体中，滑块可以具有没有阀80的通道26，于是所述通道总是打开的。在滑块20下面的基片30和32也能在除了一小部分之外的任一点被密封在一起。因此，袋子10可以在除了定位滑块20的位置之外的每一个滑块20的位置进行密封，于是通道26直接就在打开部分之上。滑块的位置在此实施例中充当阀的作用，以打开或者封闭所述通道。在生产中，首先将滑块安置在打开部分之上以接收进入通道的喷嘴，例如用饮用流体将袋子填满。然后，推动滑块到侧面，密封运输或者储存过程中的内容物。当出售时，消费者可以移动滑块到入口位置并插入吸管来饮用内容物。In another embodiment, thebag 10 is provided with a slider having two connectingsides 48 . Thebag opening 16 is then always closed on both sides of theslider 20 . In yet another variant, the slide can have thechannel 26 without the valve 80, so that said channel is always open.Substrates 30 and 32 underslider 20 can also be sealed together at any point except a small portion. Thus, thebag 10 can be sealed at eachslider 20 except where theslider 20 is located so that thechannel 26 is directly over the opening. The position of the slider acts in this embodiment as a valve to open or close the passage. In production, the slider is first placed over the opening to receive the nozzle entering the channel, for example to fill the bag with drinking fluid. Then, push the slider to the side to seal the contents during transport or storage. When ready for sale, the consumer can move the slider to the inlet position and insert the straw to drink the contents.

对于本领域的那些技术人员可以认识到，前述说明是针对优选实施例而言，在附后的权利要求的广义范围内没有脱离本发明的精神，各种改变和改进是可能的。例如，当参照具有一个或者两个本体的袋子时，也可以在本申请有益于使用的单个袋子内使用更多的本体。对于本领域的那些技术人员将认识到各种其它的改进，但不是在此描述的任何其它细节。It will be appreciated by those skilled in the art that the foregoing description is of a preferred embodiment and that various changes and modifications are possible without departing from the spirit of the invention within the broad scope of the appended claims. For example, when referring to a bag having one or two bodies, more bodies may also be used within a single bag to the benefit of the present application. Various other modifications will be recognized by those skilled in the art, but not in any other detail described herein.
