Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of container sealing structure, in particular to a low-cost and high-sealing-effect container sealing structure. BACKGROUND

[0002] The commonly used container packaging of various materials, box type, cup type, jar type and the like are usually sealed by only adopting the two-structure buckling mode of the cover body and the container. The container product usually adopts a tearable label to assist in judging whether the product container has been opened. The above-mentioned pseudo-sealing mode can achieve the function of assisting in judging, but cannot assist in sealing. The sealing performance cannot be guaranteed by only adopting the two-structure buckling mode of the cover body and the container. Therefore, there is still room for improvement.

[0003] According to the search, the patent with the Chinese patent application number CN200420037947.1 discloses a beverage container cover, the top surface of which has a concave but not through circular groove. And a disposable ultra-thin sealed beverage container has the container cover and the container body, and the container cover and the container body are buckled by a locking mechanism, and the container wall thickness S is less than or equal to 0.5 mm. The beverage container cover in the above-mentioned patent has the following disadvantages: although the circular groove is provided to prevent repeated use, the overall sealing performance of the container is insufficient, and there is still room for improvement.
