背景技术Background technique
饮料杯一般使用聚酯(PET)、聚乙烯(PE)、聚丙烯(PP)为原料，添加了相应的有机溶剂后，经过高温加热后，通过塑料模具经过吹塑、挤吹、或者注塑成型而成，由于塑料很难降解，回收利用率低，因此非常不环保，目前很多物品开始采用纸质环保材料，例如手提袋、牛奶袋等，但是，目前还没有出现使用纸质材料制作饮料杯的先例，而纸质材料的硬度、可塑造度完全可以用于饮料杯的制作，因此，将纸质材料作为饮料杯的主要制作材料，不仅环保安全，而且外观比塑料瓶更加的美观大气，将获得更多人的喜爱。但是目前所使用的饮料杯的盖体是直接盖设在容器上的，并不紧，而容置撒泼出饮料或悬浮液，同时也很容易在外力下脱落。Beverage cups generally use polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding corresponding organic solvents, after high temperature heating, through plastic molds through blow molding, extrusion blow molding, or injection molding Because plastic is difficult to degrade and recycling rate is low, it is very environmentally friendly. At present, many items have begun to use paper-based environmentally friendly materials, such as handbags and milk bags. However, there has not been any paper materials used to make beverage cups. The precedence of paper materials, and the hardness and moldability of paper materials can be used in the production of beverage cups. Therefore, using paper materials as the main material for making beverage cups is not only environmentally friendly and safe, but also more beautiful than plastic bottles. Will be loved by more people. However, the lid of the currently used beverage cup is directly placed on the container, and it is not tight, and the beverage or suspension is contained and spilled, and it is also easy to fall off under external force.

It can be understood that both the container 10 and the cover 20 can be made of pressed paper or paper-plastic materials.
所述容器10包括一个本体11，以及一个从所述本体11的边缘延伸出的卡接部12。可以想到的是，所述容器10还可以包括其他的一些功能结构，如杯柄部，装饰部等等，其为本领域技术人员所习知的技术，在此不再赘述。所述本体11用于盛放各种物品，如液体，悬浮液等，其为现有技术，在此不再赘述。所述卡接部12包括一个与所述本体11连接的连接部121，以及一个从连接部121延伸出的卡环122。在沿所述本体121的中心轴的截面上，所述连接部121的轮廓线与所述本体11的中心轴之间的夹角为锐角且所述卡环122的轮廓线与所述本体11的中心轴平行。The container 10 includes a body 11 and a clamping portion 12 extending from the edge of the body 11. It is conceivable that the container 10 may also include some other functional structures, such as a cup handle portion, a decoration portion, and the like, which are techniques known to those skilled in the art, and will not be repeated here. The body 11 is used to store various items, such as liquids, suspensions, etc., which is the prior art and will not be described here. The snap portion 12 includes a connecting portion 121 connected to the body 11, and a snap ring 122 extending from the connecting portion 121. In a cross section along the central axis of the body 121, the angle between the contour line of the connecting portion 121 and the central axis of the body 11 is an acute angle and the contour line of the snap ring 122 and the body 11 The central axis is parallel.
所述盖体20包括一个盖体21，一个从所述盖体21的边缘延伸出的盖壁22， 以及一个设置在所述盖壁22内侧壁上的凸缘23。可以想到的是，所述盖体20还可以包括其他的一些功能结构，如提手，插孔等。所述盖体21为本领域技术人员所习知的技术，在此不再赘述。所述凸缘23与所述盖底21间隔设置。所述卡环122沿所述本体11的中心轴的方向上的高度小于或等于所述凸缘23与所述盖体21之间的最小距离。在所述盖体20盖设在所述容器10上时所述卡环122夹设在所述凸缘23与盖底21之间。为了使所述卡环122与所述盖壁22面接触，在沿所述本体11的中心轴的截面上所述卡环122的轮廓线与所述本体11的中心轴平行。另外，为了增加提供更大的容错率，所述凸缘23与所述盖壁22的自由端间隔设置。在沿所述本体11的中心轴的截面上所述凸缘23的轮廓线可以为弧形。当然可以想到的是，所述凸缘23的轮廓线还可以为其他形状，如波浪形，齿状形等等，其可以根据实际需要进行选择。为了更好的达到卡接的效果，所述本体11的侧壁到所述卡环122的距离与所述凸缘23的弧形的拱高相等。The cover body 20 includes a cover body 21, a cover wall 22 extending from the edge of the cover body 21, and a flange 23 provided on the inner side wall of the cover wall 22. It is conceivable that the cover body 20 may also include other functional structures, such as handles, jacks, and the like. The cover 21 is a technology known to those skilled in the art, and will not be repeated here. The flange 23 is spaced apart from the cover bottom 21. The height of the snap ring 122 along the central axis of the body 11 is less than or equal to the minimum distance between the flange 23 and the cover 21. When the lid body 20 is placed on the container 10, the snap ring 122 is sandwiched between the flange 23 and the lid bottom 21. In order to make the snap ring 122 come into surface contact with the cover wall 22, the outline of the snap ring 122 is parallel to the central axis of the body 11 in a section along the central axis of the body 11. In addition, in order to increase and provide greater error tolerance, the flange 23 is spaced from the free end of the cover wall 22. The outline of the flange 23 may be arc-shaped in a section along the central axis of the body 11. Of course, it is conceivable that the outline of the flange 23 can also have other shapes, such as a wave shape, a tooth shape, etc., which can be selected according to actual needs. In order to achieve a better clamping effect, the distance between the side wall of the body 11 and the snap ring 122 is equal to the arcuate arch height of the flange 23.
与现有技术相比，本实用新型所提供的纸塑容器的扣合结构的容器10与盖体20分别具有所述的卡接部12与凸缘23，在将所述盖体20盖设在所述容器10上时，由于所述卡环122的外径与所述盖壁22的内径相当，因此在所述凸缘23的抵顶下所述卡环122发生变形，而该卡环122越过所述凸缘23时所述卡环122恢复到原始状态或仍然处于变形状态而抵顶在所述盖壁22上，并夹设在所述盖底21与凸缘23之间，完成该容器10与盖体20之间的盖合而不会在没有外力时脱离。Compared with the prior art, the container 10 and the cover 20 of the paper-plastic container provided by the utility model respectively have the engaging portion 12 and the flange 23, and the cover 20 is covered When on the container 10, since the outer diameter of the snap ring 122 is equal to the inner diameter of the cover wall 22, the snap ring 122 deforms under the abutment of the flange 23, and the snap ring When 122 passes over the flange 23, the snap ring 122 returns to the original state or is still in a deformed state and abuts against the cover wall 22, and is sandwiched between the cover bottom 21 and the flange 23 to complete The lid between the container 10 and the lid body 20 does not come off when there is no external force.
