本发明与现有技术相比，有益效果如下：Compared with the prior art, the present invention has the following beneficial effects:
本发明技术方案提供的出液控制阀，将该出液控制阀卡入容器本体内后，准备使用前，容器本体处于自然倒立状态，此时弧形隔膜呈上拱状态，在内容物压力作用下，整个弧形隔膜带动加强肋整体受向下的压力，由于弧形隔膜边缘较薄，首先向下拉直，上拱的加强肋会相应地展平，由于加强肋具有一定的抗压强度，加强肋内部各处承受压应力，从而呈现拱桥效应，使得整体处于受力平衡状态，切缝被压紧，以防止内容物滴漏。当容器本体受到挤压时，中间部分的隔膜及加强肋开始向下凹陷变形，随着用力加大，下凹部分扩展直至整个加强肋呈下凹状态，此时整个加强肋内部受拉应力，内容物将切缝撑开，可挤出内容物，由于挤出过程是渐进变化的，且加强肋的设计结构使切缝的张开过程连续且柔和，开口大小与挤压力度基本呈线性关系，因此不存在爆冲现象。同理，当给容器本体松压时，与挤压过程刚好相反，容器内的负压及弧形隔膜和加强肋自身的形状记忆恢复力，使阀门开口闭合，加强肋及隔膜恢复到初始状态，在恢复过程中，能够将阀门外的残留内容物部分或全部吸回到容器本体内，以保持口部的清洁。由此，利用该出液控制阀能够提高包装容器的使用效果。In the liquid outlet control valve provided by the technical solution of the present invention, after the liquid outlet control valve is clamped into the container body, before ready to use, the container body is in a natural inverted state. The entire arc-shaped diaphragm drives the overall reinforcement rib to be under downward pressure. Since the edge of the arc-shaped diaphragm is thin, it first pulls down and straightens, and the upper arched reinforcement rib will be flattened accordingly. Since the reinforcement rib has a certain compressive strength, The interior of the reinforcing rib is subjected to compressive stress, thereby presenting an arch bridge effect, making the whole in a state of force balance, and the slits are compressed to prevent the contents from dripping. When the container body is squeezed, the diaphragm and reinforcing rib in the middle part begin to dent downward and deform. As the force increases, the concave part expands until the entire reinforcing rib is in a concave state. At this time, the entire reinforcing rib is under tensile stress. The content will open the slit, and the content can be extruded. Since the extrusion process changes gradually, and the design structure of the reinforcing rib makes the opening process of the slit continuous and soft, the size of the opening and the extrusion force are basically linear. , so there is no bursting phenomenon. In the same way, when the container body is released, it is just the opposite of the extrusion process. The negative pressure in the container and the shape memory restoring force of the arc diaphragm and the reinforcing rib itself close the valve opening, and the reinforcing rib and diaphragm return to the initial state. , During the recovery process, part or all of the residual contents outside the valve can be sucked back into the container body to keep the mouth clean. Therefore, the use effect of the packaging container can be improved by the liquid discharge control valve.

为使本发明的目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而非全部实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the objectives, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
实施例一：Example 1:
请参照图1和图2所示，为本发明实施例提供的一种出液控制阀100，其包括：本体部1、弧形隔膜2和加强肋3。Referring to FIG. 1 and FIG. 2 , a liquid
本体部1上开设有中心孔11；弧形隔膜2设置于本体部1上，并封堵中心孔11的一端开口；加强肋3设置于弧形隔膜2上，并位于弧形隔膜2的外凸面所在的一侧，弧形隔膜2和加强肋3均由具有形状记忆特性的材料制成，且加强肋3上具有贯穿加强肋和隔膜的切缝4。The
在上述实施例中，具体使用时，如图4所示，为出液控制阀100尚未使用状态下的结构示意图，参照图11所示，将该出液控制阀100卡入容器本体301内后，准备使用前，容器本体301处于自然倒立状态，参照图5所示，此时弧形隔膜2呈上拱状态，在内容物压力作用下，整个弧形隔膜2带动加强肋3整体受向下的压力，由于弧形隔膜2边缘较薄，首先向下拉直，上拱的加强肋3会相应地展平，由于加强肋3具有一定的抗压强度，加强肋3内部各处承受压应力，从而呈现拱桥效应，使得整体处于受力平衡状态，切缝被压紧，以防止内容物滴漏。参照图6所示，当容器本体301受到挤压时，中间部分的弧形隔膜2及加强肋3开始向下凹陷变形，继续参照图7和图8所示，随着用力加大，下凹部分扩展直至整个加强肋3呈下凹状态，此时整个加强肋内部受拉应力，内容物将切缝4撑开(即图3中出液控制阀所处的状态)，从而可挤出内容物。由于挤出过程是渐进变化的，且加强肋3的设计使得切缝4的张开过程连续且柔和，参照图9所示，开口大小与挤压力度基本呈线性关系，因此不存在爆冲现象。同理，当给容器本体301松压时，与挤压过程刚好相反，容器本体301内的负压及弧形隔膜2和加强肋3自身的形状记忆恢复力，使阀门开口闭合，弧形隔膜2及加强肋3恢复到初始状态，在恢复过程中，能够将阀门外的残留内容物部分或全部吸回到容器本体301内，以保持口部的清洁。由此，利用该出液控制阀100能够提高包装容器的使用效果。需要说明的是，本实施例中，图9所示的压力与开口面积及出液量的关系曲线图只是为了方便说明而做的定性示意图，实际曲线会因产品使用场合、产品使用要求、产品结构参数的不同而不同。In the above embodiment, when in use, as shown in FIG. 4 , it is a schematic structural diagram of the liquid
在上述实施例中，对加强肋3的数量不做限定。优选的，加强肋3的数量为两个，两个加强肋3在本体部1的横截面上的投影相互垂直。由此，可形成十字形开口，当受到挤压力后，十字形开口能够均匀地张开，从而能够均匀地挤出容器本体内的内容物。当然，在其他实施例中，加强肋3的数量也可以是四个，从而使得四个加强肋3形成“米”字形形状。In the above embodiment, the number of the reinforcing
参照图2所示，在上述实施例中，优选的，弧形隔膜2的内凹面上与加强肋3相对应的位置处具有V型槽21，切缝4位于V型槽21的底部。具体的，在本实施例中，通过在弧形隔膜2的内凹面上与加强肋3相对应的位置挖出一定长度的两条V型槽21，从而能够利用锋利的刀片沿着两条V型槽21的根部分别切开相应长度的切缝4。利用该V型槽21能够在切割操作时对刀片起导向作用，从而便于精确切口的位置，同时，该V型槽21还具有调节出液状态、稳定出液流的作用，并能够更加容易地回吸内容物，从而减少内容物残留，保证口部洁净。Referring to FIG. 2 , in the above embodiment, preferably, the inner concave surface of the arc-shaped
在上述实施例中，优选的，本体部1上具有第一连接部(图中未示出)，本体部1能够插入容器本体的开口部内，以使第一连接部能够与设置在容器本体上的第二连接部连接，从而固定本体部1与容器本体的相对位置；弧形隔膜2朝向容器本体的底部弯曲。具体的，在该实施例中，出液控制阀100可充当盖子使用，从而可将出液控制阀100直接安装到容器本体上，使得容器本体能够控制内容物的出液量。为提高容器本体的密封性，可将本体部1的外壁与容器本体的开口部的内壁过盈配合，或在本体部1的外壁与容器本体的开口部的内壁之间设置密封结构(例如：密封圈等)。In the above embodiment, preferably, the
在上述实施例中，对弧形隔膜2的弯曲方向不做具体限定；参照本申请图1和图2所示，弧形隔膜2沿远离中心孔11的另一端的方向弯曲设定的弧度。参照图10所示，弧形隔膜2还可以沿靠近中心孔11的另一端的方向弯曲设定的弧度，其工作原理与图1和图2中所示的出液控制阀的工作原理相同，只要安装使用时，保证弧形隔膜2的弯曲方向朝向容器本体的底部即可。In the above embodiment, the bending direction of the arc-shaped
在上述实施例中，优选的，本体部1、弧形隔膜2和加强肋3一体成型。由此不仅能够保证本体部1、弧形隔膜2和加强肋3之间的密封性，而且能够避免二次组装，从而有利于提高生产效率。In the above embodiment, preferably, the
实施例二：Embodiment 2:
参照图11所示，本发明实施例还提供了一种可控制出液量的盖子200，其包括上盖201、下盖202和本发明实施例一所述的出液控制阀100。Referring to FIG. 11 , an embodiment of the present invention further provides a
上盖201可翻转地安装在下盖202上，下盖202的中心具有通道部203；本体部1容置在通道部203内，且弧形隔膜2沿远离上盖201的方向弯曲，上盖201能够与下盖202相扣合，以封堵中心孔11另一端的开口。The
在本实施例中，具体使用时，参照图12所示，可将盖子200盖设到容器本体301上，并使得通道部203插设在容器本体301的开口部内。当需要取用容器本体301的内容物时，可挤压容器本体301，从而使得通道部203内的出液控制阀100依次经历从图4至图8所示的过程，进而能够将内容物连续且柔和地挤出，当取用完毕后，松开对容器本体301的挤压，则出液控制阀100在容器本体301内的负压及弧形隔膜2和加强肋3自身的形状记忆恢复力作用下恢复原状，并将开口部的内容物吸回到容器本体301内部，以保证开口部的洁净。由此，利用该盖子200能够对出液量进行控制，以提高用户的使用效果。In this embodiment, in specific use, as shown in FIG. 12 , the
在上述实施例中，优选的，还包括密封环(图中未示出)，密封环套设在本体部1上，并位于本体部1的外壁与通道部203的内壁之间，以封堵本体部1的外壁与通道部203的内壁之间的缝隙。由此，利用该密封环能够提高出液控制阀100与下盖202之间的密封性，从而能够避免内容物从本体部1的外壁与通道部203的内壁之间的缝隙流出。In the above embodiment, it is preferable to further include a sealing ring (not shown in the figure), the sealing ring is sleeved on the
能够理解的是，通过设置密封环提高密封性仅为其中一种较好的实施方式，还可以通过其他方式来实现密封的效果，例如：将本体部1的外壁与通道部203的内壁过盈配合，或在本体部1的外壁与通道部203的内壁之间填充胶状物等。It can be understood that improving the sealing performance by providing a sealing ring is only one of the better embodiments, and other methods can also be used to achieve the sealing effect, for example: interfering the outer wall of the
