Abstract
本发明涉及一种接缝式热成型塑料盖，包括珠状和密封层，所述珠状由长条状固定带两端通过热压固接形成整体，所述珠状在其内圈设置有支撑凸沿，所述密封层置于所述支撑凸沿上方或者下方，所述密封层与所述支撑凸沿通过热合形成整体盖体。本发明改变了传统塑料盖冲压成型的制造方法，将塑料盖分为由长条状固定带两端连接形成的珠状和密封层，整个塑料盖整体厚度均匀、结构牢固。同时生产的过程中，塑料片材切割成条状带坯的过程还大大减少了边角料的产生。
The invention relates to a seam-type thermoformed plastic cover, which includes a bead shape and a sealing layer. The supporting lip, the sealing layer is placed above or below the supporting lip, and the sealing layer and the supporting lip are heat-bonded to form an integral cover. The invention changes the traditional manufacturing method of stamping and forming of the plastic cover, divides the plastic cover into a bead shape and a sealing layer formed by connecting two ends of a long strip-shaped fixing belt, and the whole plastic cover has a uniform thickness and a firm structure. At the same time, in the process of production, the process of cutting the plastic sheet into strips also greatly reduces the generation of leftovers.
Description
技术领域technical field
本发明涉及塑料盖领域，具体指有一种接缝式热成型塑料盖。The invention relates to the field of plastic covers, in particular to a seam-type thermoformed plastic cover.
背景技术Background technique
一次性的塑料杯盖、碗盖及餐盒盖是快餐行业乃至日常家居广泛应用的产品，用量巨大，可以帮助杯子、碗等容器进行密封，防止容器内的液体洒出。同时还具有无毒、无异味等优点。Disposable plastic cup lids, bowl lids, and lunch box lids are widely used in the fast food industry and even in daily households. They are used in a huge amount and can help seal cups, bowls and other containers to prevent the liquid in the container from spilling. At the same time, it also has the advantages of non-toxic and no peculiar smell.
目前市场上的一次性的塑料杯盖、碗盖及餐盒盖产品的生产，以冲压成型占多数，一般采用薄膜状塑料，加热后通过模具进行冲压，形成相应的图案以及形状，最后切割出所需的部分。这样的方法虽然简单，但是塑料盖的冲压处由于冲压作用，冲压处明显变薄，影响到盖子的密合性能甚至出现破损等现象。同时，采用冲压的方法还会产生大量的边角料，造成一定的浪费。At present, the production of disposable plastic cup lids, bowl lids and lunch box lids on the market is mostly stamping. Generally, film-like plastics are used. After heating, they are stamped through molds to form corresponding patterns and shapes, and finally cut out. required part. Although such a method is simple, the stamping part of the plastic cover is obviously thinned due to the stamping effect, which affects the sealing performance of the cover and even breaks. Simultaneously, adopting the method of stamping also can produce a large amount of scraps, cause certain waste.
针对上述的现有技术存在的问题设计一种可以节省材料并且防止冲压处出现破损的塑料盖是本发明研究的目的。Aiming at the above-mentioned problems in the prior art, it is the purpose of the present invention to design a plastic cover that can save material and prevent damage at the stamping place.
发明内容Contents of the invention
针对上述现有技术存在的问题，本发明在于提供一种接缝式热成型塑料盖，能够有效解决上述现有技术存在的问题。Aiming at the above-mentioned problems in the prior art, the present invention provides a seamed thermoformed plastic cover, which can effectively solve the above-mentioned problems in the prior art.
本发明的技术方案是：Technical scheme of the present invention is:
一种接缝式热成型塑料盖，包括珠状和密封层，所述珠状由长条状固定带两端通过热压固接形成整体，所述珠状在其内圈设置有支撑凸沿，所述密封层置于所述支撑凸沿上方或者下方，所述密封层与所述支撑凸沿通过热合形成整体盖体。A seam-type thermoformed plastic cover, including a bead and a sealing layer, the bead is integrally formed by hot-pressing the two ends of a strip-shaped fixing belt, and the bead is provided with a supporting convex edge on its inner ring , the sealing layer is placed above or below the supporting lip, and the sealing layer and the supporting lip are heat-bonded to form an integral cover.
所述密封层是薄膜或淋膜纸板或者板材或者片材中的一种。The sealing layer is one of film or coated cardboard or plate or sheet.
所述珠状是方形、圆形或其他规则几何形状中的一种。The bead shape is one of square, round or other regular geometric shapes.
本发明的优点：Advantages of the present invention:
本发明改变了传统塑料盖冲压成型的制造方法，将塑料盖分为由长条状固定带两端连接形成的珠状和密封层，整个塑料盖整体厚度均匀、结构牢固。同时生产的过程中，塑料片材切割成条状带坯的过程还大大减少了边角料的产生。The invention changes the traditional manufacturing method of stamping and forming of the plastic cover, and divides the plastic cover into a bead shape and a sealing layer formed by connecting two ends of a long strip-shaped fixing belt. The entire plastic cover has a uniform thickness and a firm structure. At the same time, in the process of production, the process of cutting the plastic sheet into strips also greatly reduces the generation of leftovers.
