Multi-embedded packing leakage-proof box body combined structure

Abstract

The invention provides a multi-embedded packing leakage-proof box body combined structure. The multi-embedded packing leakage-proof box body combined structure comprises a bottom shell, a surface shell and an inner shell, an opening of the bottom shell is provided with a lip edge, an opening of the inner shell is provided with a shell edge, and an opening of the surface shell is provided with a lip edge. The inner shell covers the bottom shell and the surface shell covers the inner shell in sequence, then the shells can be combined into a whole easily and synchronously by means of one-time force application and downward pressing, and a good sealing effect is achieved among the shells. At least a group of tough sheets are arranged on the outside of the lip edge of the bottom shell and at least one group of corresponding U-shaped buckling grooves are formed in the outer side of the lip edge of the matched surface shell, so that the rapid, firm and stable combination effect is achieved.

Description

technical field [0001] The present invention relates to a box assembly structure, in particular to a re-embedded tight leak-proof box assembly structure with tight combination and leak-proof effect. Background technique [0002] The common box body, one of the components includes a shell and a cover that cooperate with each other; the second component has a built-in inner shell in addition to the shell and the cover that match. Regardless of the box structure, the design is based on actual use requirements, so there are inevitably some shortcomings in use. For example, when the combination of the shell and the cover is easy to open, the tightness of the combination of the two is not good, and liquid leakage is prone to occur; on the contrary, when the combination of the shell and the cover is very tight and firm, It will also be difficult to open, and once excessive force is applied, the cover will inevitably be cracked and damaged, and cannot be reused again, and must be d...

Regardless of the box structure, the design is based on actual use requirements, so there are inevitably some shortcomings in use

For example, when the combination of the shell and the cover is easy to open, the tightness of the combination of the two is not good, and liquid leakage is prone to occur; on the contrary, when the combination of the shell and the cover is very tight and firm, It will also be difficult to open. Moreover, once excessive force is applied, it will inevitably cause the cover to crack and be damaged, making it impossible to reuse it. It must be discarded and more plastic waste will be created.

[0003] Secondly, the box body with the inner shell is usually designed to form a hanging shape simply by placing the peripheral edge, without any fastening, sealing or leak-proof design, which leads to the fact that when the box body actually holds different types of food, Shaking or tilting during handling or transportation will cause the juice contained in it to mix with other foods, which will not only affect the taste of different foods, but also cause the taste of the food to deteriorate

In particular, the design of the inner shell is only convenient for inserting but ignoring the taking out. As a result, the hand often directly touches the food when taking it out, and the hygienic situation is worrying.

[0004] Furthermore, due to the manufacturing method of the box body, the material of the formed shell, cover and inner shell is relatively thin, which is not only force majeure but also prone to deformation. The combination of the shell and the cover, or the shell and the cover The cover of the body and the inner shell is obviously insufficient in the degree of stability and anti-leakage after the combination
