A first layer of L1 paperboard is bonded to a second layer of L2 uncoated paperboard with afibrous layer 50 . One of the uncoated sides of the first layer L1 is bonded to one of the uncoated sides of the second layer L2; the adhesive treatment or glue forms a glue oradhesive layer 54 therebetween.

在一个示例中，28 pt CBS或CNK纸板的第一片材结合到28 pt CBS或CNK纸板的第二片材。这产生了厚度为大约0.056”（约1.4 mm）的基材，该基材在其相对面上具有涂层。这样的基材的优点是在不包括聚合物材料或塑料材料的情况下增加了强度，这样的基材可提供环境益处并且更容易回收。在其他实施例中，一层材料或一片材材料的涂覆侧结合到另一层材料或另一片材材料的未涂覆侧。在替代性实施例中，一层材料或一片材材料的涂覆侧结合到另一层材料或另一片材材料的涂覆侧。In one example, a first sheet of 28 pt CBS or CNK paperboard is bonded to a second sheet of 28 pt CBS or CNK paperboard. This results in a substrate having a thickness of approximately 0.056" (approximately 1.4 mm) with a coating on its opposite side. The advantage of such a substrate is the added benefit of not including polymeric or plastic materials. strength, such substrates can provide environmental benefits and are easier to recycle. In other embodiments, the coated side of one layer or sheet of material is bonded to the uncoated side of another layer or sheet of material In an alternative embodiment, the coated side of one layer or sheet of material is bonded to the coated side of another layer or sheet of material.

将理解，经选择以用于结合在一起的纸板基材的厚度或卡尺厚度（caliper）（密度或重量）可具有不同的厚度或重量。还将理解，经选择的纸板基材的厚度或卡尺厚度（密度或重量）可以是基于物品承载器旨在支撑的重量或负荷来选择的，例如用于包装更大体积/更重饮料罐，或者更大数量的饮料罐的物品承载器可由更厚的（或重量更重的）纸板基材形成。类似地，当物品承载器旨在支撑更大的负荷时，物品承载器可由结合在一起的纸板基材的更大数量的层（layers/plies）形成。It will be appreciated that the thickness or caliper (density or weight) of the paperboard substrates selected for bonding together can have different thicknesses or weights. It will also be appreciated that the thickness or caliper thickness (density or weight) of the cardboard substrate selected may be selected based on the weight or load that the article carrier is intended to support, such as for packaging larger volume/heavier beverage cans, Or an item carrier for a larger number of beverage cans may be formed from a thicker (or heavier weight) cardboard substrate. Similarly, when the article carrier is intended to support larger loads, the article carrier may be formed from a larger number of layers/plies of cardboard substrates bonded together.

胶水层可由对纸板具有良好亲和力的任何粘合剂形成，诸如水性胶（例如，白色工艺胶、黄色木胶和聚醋酸乙烯酯—PVA胶）。The glue layer can be formed from any adhesive that has a good affinity for paperboard, such as water-based glues (eg, white craft glue, yellow wood glue, and polyvinyl acetate-PVA glue).

纸板的两个或更多个片材被层压在一起形成层压纸板，且然后可将层压纸板模切成承载器坯件10，诸如，图1的承载器坯件。Two or more sheets of paperboard are laminated together to form a laminated paperboard, and the laminated paperboard can then be die cut into acarrier blank 10 , such as the carrier blank of FIG. 1 .

在一些实施例中，坯件和物品承载器由纸板原料的可商购的两个或更多个片材或卷材形成，所述片材或卷材结合在一起以形成层压结构。所设想的是，层压结构由已在造纸厂中干燥的纸板原料形成，该纸板原料还可在结合在一起之前经受一种或多种干端处理，诸如但不限于轧光和/或用涂层修整。In some embodiments, the blank and article carrier are formed from two or more commercially available sheets or rolls of paperboard stock that are bonded together to form a laminate structure. It is envisaged that the laminate structure is formed from paperboard stock that has been dried in the paper mill, which may also be subjected to one or more dry end treatments such as, but not limited to, calendering and/or prior to joining together. Coating trim.

在一些实施例中，可处理或调节纸板基材的待结合到另一纸板基材的表面以改进结合力，诸如但不限于，通过穿孔或以其他方式中断该表面，例如利用部分深度切口中断该表面。In some embodiments, the surface of a paperboard substrate to be bonded to another paperboard substrate may be treated or conditioned to improve the bond, such as, but not limited to, by perforating or otherwise interrupting the surface, for example by interrupting with partial depth cuts the surface.

顶部接合承载器90包括均匀地结合的层。在顶部接合承载器90包括接合齿的那些实施例中，每个齿具有均匀地结合的纸板层。这比具有多个纸板层且这些纸板层具有非胶合结构的物品承载器、以及比具有后胶合结构（其中纸板层在纸板的每个层被模切之后被粘附）的物品承载器有利。在这样的后胶合物品承载器中，因为每个层已经被模切，所以这些层通过点状胶合粘附在一起且因此承载器不具有均匀地胶合的层。在承载器包括接合齿的情况下，这些齿不包括均匀地胶合的层并且可由未结合的层形成。Thetop bonding carrier 90 includes uniformly bonded layers. In those embodiments where thetop engagement carrier 90 includes engagement teeth, each tooth has a uniformly bonded cardboard layer. This is advantageous over article carriers having multiple cardboard layers with non-glued constructions, and over article carriers with post-glued constructions in which the cardboard layers are adhered after each layer of cardboard is die cut. In such post-glued article carriers, since each layer has been die cut, the layers are adhered together by spot gluing and thus the carrier does not have uniformly glued layers. Where the carrier includes engaging teeth, these teeth do not include a uniformly glued layer and may be formed from unbonded layers.

在一些实施例中，至少一个抗撕裂层可设置在第一层基材和第二层基材之间，这样的基材可通过结合材料的两个片材形成，其中的至少一个片材包括层压到其的抗撕裂层。这可具有增加基材强度的优点。In some embodiments, at least one tear resistant layer may be disposed between the first layer of substrate and the second layer of substrate, such substrate may be formed by joining two sheets of material, at least one of the sheets Includes tear resistant layer laminated to it. This can have the advantage of increasing the strength of the substrate.

主面板12可包括层压到纸板层的抗撕裂层。可选地，它包括在纸板基材和抗撕裂层之间的粘合剂层。抗撕裂层可设置在纸板基材的未涂覆侧之上，并且可由聚合物材料形成并固定到基材。抗撕裂层将韧性赋予层压结构。合适的抗撕裂材料可包括但不限于抗撕裂层压片材材料，例如NATRALOCK®，其可包括一层n轴取向的膜，例如，MYLAR®，其是双轴取向聚酯、取向尼龙、交叉层压聚烯烃或高密度聚烯烃。这些材料的取向和交叉层压结构促成了抗撕裂特性。而且，抗撕裂性可归因于抗撕裂材料的化学性质，抗撕裂材料诸如挤出茂金属催化聚乙烯（mPE）。Themain panel 12 may include a tear resistant layer laminated to the paperboard layer. Optionally, it includes an adhesive layer between the paperboard substrate and the tear resistant layer. A tear resistant layer may be disposed over the uncoated side of the paperboard substrate, and may be formed from a polymeric material and secured to the substrate. The tear resistant layer imparts toughness to the laminate structure. Suitable tear resistant materials may include, but are not limited to, tear resistant laminate sheet materials such as NATRALOCK®, which may include a layer of n-axis oriented film, such as MYLAR®, which is biaxially oriented polyester, oriented nylon , cross-laminated polyolefin or high density polyolefin. The orientation and cross-laminate structure of these materials contribute to tear resistance. Furthermore, tear resistance can be attributed to the chemical properties of tear resistant materials, such as extruded metallocene catalyzed polyethylene (mPE).

替代地，抗撕裂层可以是线性低密度聚乙烯（LLDPE）层。在使用线性低密度聚乙烯（LLDPE）或mPE的实施例中，不必要结合粘合剂层。也可使用具有高水平抗撕裂性的其他合适材料。Alternatively, the tear resistant layer may be a linear low density polyethylene (LLDPE) layer. In embodiments using linear low density polyethylene (LLDPE) or mPE, it is not necessary to bond the adhesive layer. Other suitable materials with high levels of tear resistance can also be used.

粘合剂层可由聚烯烃材料形成，诸如低密度聚乙烯（LDPE）。粘合剂层可放置在基材和抗撕裂层之间以将抗撕裂层固定到基材。The adhesive layer may be formed of a polyolefin material, such as low density polyethylene (LDPE). An adhesive layer can be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.

转向由坯件10构造承载器90，可将坯件10应用于一组物品B。将坯件10相对于该组物品B降低。使坯件10的物品保持结构RT1、RT2、RT3、RT4中的每一个与该组中的相应物品B对准。物品B的部分穿过主面板12。主面板12的绕物品保持结构RT1、RT2、RT3、RT4中的每一个的有齿区域可被折叠出主面板12的平面。Turning to constructingcarrier 90 from blank 10, blank 10 may be applied to a set of articles B. The blank 10 is lowered relative to the set of articles B. Each of the item retention structures RT1, RT2, RT3, RT4 of the blank 10 is aligned with the corresponding item B in the set. Portions of item B pass throughmain panel 12 . The toothed area of themain panel 12 around each of the article retention structures RT1 , RT2 , RT3 , RT4 may be folded out of the plane of themain panel 12 .

主面板12的每个有齿区域可绕物品中的一个（该物品被接收在物品保持结构RT1、RT2、RT3、RT4中的相应一个中）折叠；坯件10可绕物品B变形，例如但不限于物品B的肩部部分，在物品B是罐的情况下，肩部部分可由颈缩部提供。Each toothed area of themain panel 12 can be folded around one of the articles received in a corresponding one of the article retention structures RT1, RT2, RT3, RT4; the blank 10 can be deformed around article B, for example but Not limited to the shoulder portion of the item B, where the item B is a can, the shoulder portion may be provided by the necking.

主面板12的齿的接合边缘31和不含齿的区域的接合边缘37在突起下面接合。该突起可绕物品B的物品B（其可设有凸缘）的颈部或凸边定位。当物品B是罐时，该突起可由罐的端缝提供。在其他实施例中，该突起可由物品B的脊部或底切成形部提供，或者由物品B的端部封闭件提供，例如但不限于冠形瓶塞或封闭件。以这种方式，接合边缘31、37夹持或保持物品B并防止或抑制物品B无意地与主面板12分开。图3中示出了已组装的承载器90。The engaging edges 31 of the teeth of themain panel 12 and theengaging edges 37 of the areas without teeth engage under the protrusions. The protrusion may be positioned around the neck or flange of item B of item B (which may be provided with a flange). When item B is a can, the protrusion may be provided by the end seam of the can. In other embodiments, the protrusion may be provided by a ridge or undercut formation of Article B, or by an end closure of Article B, such as, but not limited to, a crown stopper or closure. In this manner, the engagingedges 31 , 37 grip or retain the item B and prevent or inhibit the item B from being inadvertently separated from themain panel 12 . The assembledcarrier 90 is shown in FIG. 3 .

齿包括均匀地结合在一起的两层基材，这两层基材提供物品B的牢固接合。The teeth comprise two layers of substrates uniformly bonded together that provide a secure engagement of the article B.

承载器90的另一可选特征是主面板12由不与承载器90的其他部分连接的周边限定。也就是说，承载器90没有连接到其他面板，例如但不限于绕物品组的侧部延伸的侧壁面板或端壁面板。主面板12的周边因此整体由自由边缘、切割边缘或未铰接边缘限定。Another optional feature of thecarrier 90 is that themain panel 12 is defined by a perimeter that is not connected to the rest of thecarrier 90 . That is, thecarrier 90 is not connected to other panels, such as, but not limited to, side wall panels or end wall panels that extend around the sides of the group of items. The perimeter of themain panel 12 is thus entirely defined by a free edge, a cut edge or an unhinged edge.

承载器90的另一可选特征是主面板12由包括凸弯曲边缘和凹弯曲边缘的周边限定，其中，凸弯曲边缘的曲率半径基本上等于凹弯曲边缘的曲率半径，因此允许两个类似的坯件10放置成嵌套或镶嵌布置。Another optional feature of thecarrier 90 is that themain panel 12 is defined by a perimeter that includes a convex curved edge and a concave curved edge, wherein the convex curved edge has a radius of curvature substantially equal to that of the concave curved edge, thus allowing two similar Theblanks 10 are placed in a nested or mosaic arrangement.

在一些实施例中，将多个坯件1同时应用于第一组物品B。第一组物品B可划分成多个第二组物品B。因此，每个第二组物品B由第一组物品B的子集形成。在图1中所图示的实施例中，第一组物品B包括以4 × 6矩阵或阵列布置的二十四个物品，并且每个单独的坯件10A、10B、10C、10D、10E、10F容纳呈2 × 2矩阵或阵列的四个物品。In some embodiments, multiple blanks 1 are applied to the first set of articles B simultaneously. The first group of articles B may be divided into a plurality of second groups of articles B. Thus, each second set of items B is formed from a subset of the first set of items B. In the embodiment illustrated in FIG. 1 , the first set of articles B includes twenty-four articles arranged in a 4×6 matrix or array, and each individual blank 10A, 10B, 10C, 10D, 10E, 10F holds four items in a 2 x 2 matrix or array.

单独的坯件10A、10B、10C、10D、10E、10F之间的易断连接部14可在将所述多个坯件1应用于第一组物品B时分开。替代地，易断连接部14可保持完整，单独的坯件10A、10B、10C、10D、10E、10F可在销售或分销点与其他坯件分开。Thefrangible connections 14 between theindividual blanks 10A, 10B, 10C, 10D, 10E, 10F can be separated when the plurality of blanks 1 are applied to the first set B of articles. Alternatively, thefrangible connections 14 may remain intact and theindividual blanks 10A, 10B, 10C, 10D, 10E, 10F may be separated from other blanks at the point of sale or distribution.

现在参考图4，示出了本公开的附加实施例。在第二所图示的实施例中，在可能的情况下已使用相似的数字来表示相似的部分，只不过添加了前缀“100”以指示这些特征属于第二实施例。该附加实施例与第一实施例共享许多共同的特征，且因此将仅详细描述与图1至图3中所图示的实施例的差异。Referring now to FIG. 4, additional embodiments of the present disclosure are shown.

层压基材可由纸板的两个或更多个片材或卷材形成，其中的至少一个片材或卷材预印有图形或其他标记。所述两个或更多个片材或卷材在对层中的一个印刷之后被层压。以这种方式，形成了在至少一侧上具有印刷的图形或其他标记的层压基材。然后，切割已印刷的层压基材以形成承载器坯件。在层压基材由纸板的卷材形成的一些实施例中，可在切割承载器坯件之前将层压基材切割成片材。在层压基材由纸板的卷材形成的其他实施例中，不必要将层压基材切割成片材，可使用在线（inline）模切装置直接从层压基材切割承载器坯件。The laminated substrate may be formed from two or more sheets or rolls of paperboard, at least one of which is pre-printed with graphics or other indicia. The two or more sheets or webs are laminated after printing one of the layers. In this manner, a laminated substrate having printed graphics or other indicia on at least one side is formed. The printed laminate substrate is then cut to form carrier blanks. In some embodiments where the laminated substrate is formed from a roll of paperboard, the laminated substrate may be cut into sheets prior to cutting the carrier blank. In other embodiments where the laminate substrate is formed from a roll of paperboard, it is not necessary to cut the laminate substrate into sheets, and an inline die cutting device can be used to cut the carrier blank directly from the laminate substrate.

层压基材可由将未印刷纸板的两个或更多个片材或卷材结合在一起而形成。一旦层压基材形成，至少一侧就可印刷有图形或其他标记。以这种方式，形成了在至少一侧上具有印刷的图形或其他标记的层压基材。然后，切割已印刷的层压基材以形成承载器坯件。在层压基材由纸板的卷材形成的实施例中，层压基材可被在线印刷，或者可被切割成片材，然后对片材进行印刷。Laminated substrates may be formed by joining together two or more sheets or rolls of unprinted paperboard. Once the laminated substrate is formed, at least one side can be printed with graphics or other indicia. In this manner, a laminated substrate having printed graphics or other indicia on at least one side is formed. The printed laminate substrate is then cut to form carrier blanks. In embodiments where the laminate substrate is formed from a roll of paperboard, the laminate substrate can be printed in-line, or can be cut into sheets and then printed on the sheets.

将认识到，如本文中所使用的，方向参考（诸如，“顶部”、“底部”、“基底”、“前部”、“后部”、“端部”、“侧部”、“内”、“外”、“上部”和“下部”）未必将相应面板限制到这样的取向，而是可能仅用来使这些面板彼此区分开。It will be appreciated that, as used herein, directional references (such as "top", "bottom", "base", "front", "rear", "end", "side", "inside" ", "outer", "upper" and "lower") do not necessarily limit the respective panels to such orientations, but may merely serve to distinguish the panels from one another.

如本文中所使用的，术语“铰接连接部”和“折线”指代限定坯件的铰接特征、促进坯件的多个部分相对于彼此折叠、或以其他方式指示坯件的最佳面板折叠位置的各种各样的线。对“铰接连接部”的任何引用不应被解释为必定是指仅单条折线；实际上，铰接连接部能够由两条或更多条折线形成，其中，两条或更多条折线中的每一条的形状可以是直线的/线性的抑或弯曲的/曲线的。当线性的折线形成铰接连接部时，它们可设置成彼此平行或相对于彼此略微成角度。当曲线的折线形成铰接连接部时，它们可彼此相交以在被这些曲线的折线包围的区域内限定成形的面板。这样的铰接连接部的典型示例可包括成对拱形或弓形的折线，该对折线在两个点处相交，使得它们在其间限定椭圆形面板。铰接连接部可由一条或多条线性的折线以及一条或多条曲线的折线形成。这样的铰接连接部的典型示例可包括线性的折线和拱形或弓形的折线的组合，这些折线在两个点处相交，使得它们在其间限定半月形面板。As used herein, the terms "hinge connection" and "fold line" refer to hinge features that define the blank, facilitate the folding of portions of the blank relative to each other, or otherwise indicate optimal panel folding of the blank Various lines of location. Any reference to "a hinged connection" should not be construed as necessarily referring to only a single polyline; in fact, a hinged connection can be formed from two or more polylines, wherein each of the two or more polylines The shape of a strip can be straight/linear or curved/curved. When linear fold lines form hinged connections, they may be arranged parallel to each other or slightly angled relative to each other. When the fold lines of the curves form hinged connections, they may intersect with each other to define a shaped panel in the area enclosed by the fold lines of the curves. Typical examples of such hinged connections may include pairs of arcuate or arcuate fold lines that meet at two points such that they define an oval panel therebetween. The hinged connection may be formed by one or more linear polylines and one or more curvilinear polylines. Typical examples of such hinged connections may include a combination of linear fold lines and arcuate or arcuate fold lines that intersect at two points such that they define a meniscus panel therebetween.

如本文中所使用的，术语“折线”可指代以下各者中的一者：刻痕线、压纹线、凹入线、一行穿孔、一行短狭缝、一行半切口、单个半切口、中断的切割线、一行对准的狭缝、一行刻痕及上述选项的任何组合。As used herein, the term "crease line" may refer to one of the following: a score line, an embossed line, a debossed line, a row of perforations, a row of short slits, a row of half-cuts, a single half-cut, Interrupted cut lines, one row of aligned slits, one row of nicks, and any combination of the above options.

应理解，铰接连接部和折线能够各自包括形成于坯件的基材中的元件，包括穿孔、一行穿孔、一行短狭缝、一行半切口、单个半切口、切割线、中断的切割线、狭缝、刻痕、压纹线、凹入线、其任何组合等等。这些元件能够被确定尺寸并布置成提供期望的功能。例如，一行穿孔能够被确定尺寸或设计有薄弱度以限定折线和/或分割线。该行穿孔能够被设计成促进折叠且抵抗断裂，促进折叠且促进通过更多的努力使其断裂，或促进通过很少的努力使其断裂。It will be appreciated that the hinged connection and the fold line can each include elements formed in the substrate of the blank, including perforations, a row of perforations, a row of short slits, a row of half-cuts, single half-cuts, cut lines, interrupted cut lines, slits Seams, scores, embossed lines, indented lines, any combination thereof, and the like. These elements can be sized and arranged to provide the desired functionality. For example, a row of perforations can be sized or designed with weakness to define fold lines and/or dividing lines. The row of perforations can be designed to promote folding and resist breaking, promote folding and facilitate breaking with more effort, or facilitate breaking with little effort.

如本文中所使用的短语“与……对齐”指代在竖立的纸板箱中的两个或更多个元件（诸如，形成于两个叠置面板中的第一个中的孔口、以及形成于两个叠置面板中的第二个中的第二孔口）的对准。彼此对齐的那些元件可沿叠置面板的厚度方向彼此对准。例如，当第一面板中的孔口与第二面板（其放置成与第一面板成叠置布置）中的第二孔口“对齐”时，该孔口的边缘可沿着第二孔口的边缘的至少一部分延伸，且可沿第一面板和第二面板的厚度方向与第二孔口对准。The phrase "aligned with" as used herein refers to two or more elements in an erected carton (such as an aperture formed in a first of two stacked panels, and alignment of a second aperture formed in the second of the two stacked panels). Those elements that are aligned with each other may be aligned with each other in the thickness direction of the stacked panels. For example, when an aperture in a first panel is "aligned" with a second aperture in a second panel (which is placed in an overlapping arrangement with the first panel), the edge of the aperture may follow the second aperture At least a portion of the edge of the fin extends and can be aligned with the second aperture in the thickness direction of the first panel and the second panel.
