Description

Composite structure of embedded tight leak-proof box body

This creation is about the combination structure of the box body, and specifically refers to a kind of tightly integrated and leak-proof effect.

According to the common box body, one of the components includes a shell and a cover that cooperate with each other; the second composition is that in addition to the matching shell and the cover, there is more built-in shell. Regardless of the box structure, the design is based on actual use requirements, so it is inevitable that there are some shortcomings in use. For example, when the combination of the shell and the cover is easy to open, the tightness when the two is combined is not good, and liquid leakage is prone to occur; on the contrary, when the combination of the shell and the cover is quite 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, so it must be discarded to produce more plastic waste.

Secondly, a box with an inner shell is usually designed to form a hanging shape solely relying on the placement of the peripheral edge, without any fastening, tightness or leak-proof design, which causes the box to actually contain different types of food. When shaking or tilting during transportation or transportation, the juice contained in it will be mixed with other foods. Not only will the taste of different foods be affected by the mixing, but also the taste of the food will deteriorate. In particular, the inner shell is designed to facilitate insertion but neglect to take it out, resulting in that the hand often directly touches the food when taking it out, and the hygiene condition is worrying.

Furthermore, due to the way the box body is made, the molded shell, cover and inner shell The material is thin, and it is not only vulnerable to deformation, but the combination of the shell and the cover, or the combination of the shell, the cover and the inner shell, the combination of the stability and leakage resistance is obviously insufficient .

In view of this, the creator of this case will have many years of experience in the manufacturing, development and design of related products, and after detailed design and careful evaluation of the above-mentioned deficiencies, he finally achieved this practical and economically excellent creation. That is, the main purpose of this creation is to provide a combined structure of the embedded tight and leak-proof box body, so as to achieve the effect of complete tight integration and leakage prevention.

Another purpose of this creation is to provide a composite structure of the embedded tight and leak-proof box body, so as to achieve no damage during opening, assembly and removal and separation, and has strong pressure resistance and can be used repeatedly. Those who have a long life and are in line with economic benefits.

The lip is integrally formed to include an inner annular recess and a The outer stepped cladding surface; and an inner shell with an accommodating groove whose depth (capacity or space) is smaller than the recessed space of the bottom shell; a shell edge is formed in the opening of the accommodating groove with a stepped shape, which can cover and Wedge the lip of the bottom shell and press and wrap it by the lip of the face shell, and at least one set of corresponding and slightly protruding support portions is formed on the peripheral surface of the containing groove toward the center of the inner circle, The top edge of the supporting part is a reinforcing part, and the height of the reinforcing part is higher than the shell edge of the inner shell.

In one embodiment, the vertical surface of the stepped shell edge of the face shell and the vertical surface of the inner side of the lip of the bottom shell opposite to each other form a design less than ninety degrees.

In one embodiment, the supporting portion further includes an annular groove connected to the reinforcing portion to form a significant height difference and facilitate the removal of the inner shell.

In one embodiment, at least one set of corresponding protrusions is provided on the outer side of the lip of the bottom shell, each protrusion has a thin bendable tongue extending from the center, and a convex buckle is formed on a surface of the free end; The outer side of the lip of the face shell is provided with at least one set of corresponding convex parts, and a concave U-shaped buckle groove is formed in the center of each convex part, and the convex buckle can be buckled into the U-shaped buckle groove.

In one embodiment, the shape of the bottom shell and the inner shell can be mutually consistent or not consistent, or can be made of any geometric shape.

In one embodiment, a partition is added to the containing groove of the inner shell.
