Description

Technical Field

[0001] The utility model relates to the field of disposable tableware, in particular to an easy-to-open buckle structure of a disposable lunch box. Background Art

[0002] In recent years, plastics are widely used in product packaging, especially in food packaging. With the continuous advancement of plastic packaging technology, it is possible for the food industry to adopt new processes and new technologies. Plastics are widely used in product packaging, especially in food packaging, playing an irreplaceable role, and are becoming an indispensable packaging material in the food industry.

[0003] Plastic food packaging plays a vital role in food prices, safety, hygiene, and functionality. Disposable plastic lunch boxes are particularly widely used in the catering industry.

[0004] However, the existing buckle structure has a poor combination effect. Sometimes, if you are not careful, the lid may be lifted unexpectedly, causing the internal items to scatter out, resulting in poor sealing effect of the lunch box. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a disposable lunch box with an easy-to-open snap-fit ​​structure, which aims to improve the snap-fit ​​structure in the prior art. The snap-fit ​​structure has a poor bonding effect, and sometimes the box lid may be lifted unexpectedly if one is not careful, causing the internal items to scatter, resulting in poor sealing effect of the lunch box.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a disposable lunch box easy-to-open snap-fit ​​structure, comprising a box body, a box cover is arranged on the top of the box body, a first extension portion is fixedly connected to the front side of the box cover, a first inner convex portion is fixedly connected to the front side of the first extension portion, an outer top is fixedly connected to the top of the first inner convex portion, a first outer convex portion is fixedly connected to the bottom of the outer top, a folding portion is fixedly connected to the bottom of the first outer convex portion, a second extension portion is fixedly connected to the front side of the box body, a second inner convex portion is fixedly connected to the front side of the second extension portion, a second inner convex portion is fixedly connected to the top of the second inner convex portion, an inner top is fixedly connected to the bottom of the inner top, and a convenient component is arranged on the top of the box cover, and the convenient component is used to store chopsticks.

[0007] Furthermore, the convenient component includes chopsticks, which are arranged on the top of the box cover. A placement groove is provided on the top of the box cover, and chopsticks are fixedly connected to the inside of the placement groove. A tableware unsealing strip is provided on the top of the placement groove.

[0008] Furthermore, a protective film is provided on the top of the tableware unsealing strip, and an easy-tear line is provided between the protective film and the sealing film.

[0009] Furthermore, the sealing films are all arranged on the top of the box cover.

[0010] Furthermore, a non-stick section is fixedly connected to one side of the tableware unsealing strip.

[0011] Furthermore, a complementary buckling structure is formed between the first inner convex portion and the second inner convex portion.

[0012] Furthermore, an interlocking connection is formed between the first outer protrusion and the second outer protrusion.

[0013] Furthermore, the folding portion is designed to be a tilted structure.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the folded portion and the first outer convex portion will slightly deform outward due to contact with the second outer convex portion, so that the box cover can be closed downward and finally fit entirely on the outside of the extension structure. The external extension structure and the internal extension structure are completely tightly fitted and overlapped, and the sealing effect can be quite ideal by utilizing the connection of the large-area curved convex and concave joint surfaces. The extension structure of the second extension part can be embedded in the outside of the extension structure of the first extension part and tightly attached to form a buckling relationship.

[0016] 2. In the utility model, when the lunch box is in use, the sealing film can be quickly and conveniently torn open along the easy-tear line through the tableware unsealing sticker, so that the chopsticks can be taken out and the order information can be destroyed at the same time, which solves the problem of uneven tableware caused by missing chopsticks during take-out packaging. The chopsticks are stored cleanly and hygienically and are easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
