Description

Food packing box

Technical Field

The utility model relates to the technical field of food packaging, in particular to a food packaging box.

Background

Food packaging is an integral part of food goods. The food package protects the food, can prevent the damage of biological, chemical and physical external factors in the process of leaving the production place to the hands of consumers, can also have the function of keeping the food stable quality, is convenient for eating, firstly shows the appearance of the food, attracts the consumption image, and has the value beyond the material cost. Food packaging can be classified into metal, glass, paper, plastic, composite material, etc. according to packaging materials. In addition, food packages can be classified into cans, bottles, bags, pouches, rolls, boxes, and the like according to the package type. Because the raw materials of the paper are mainly plant fibers, the plant fibers are degradable and recyclable. For hygienic reasons, the food packages are mostly disposable. With the improvement of environmental awareness, paper food packages are increasingly used.

In the prior art, the bottom of many food packaging boxes adopts a box body made of paper materials, and the upper buckle cover is made of transparent plastic materials, so that the patterns and the like of food in the box body can be seen clearly through the upper cover body, and the food packaging box is suitable for selecting food. However, the paper box body is difficult to form a buckle matched with the upper cover, and the box body is generally of a paper box structure with simple style. When the cover body is matched with the box body, the cover body can be simply covered, and the cover body is easy to separate from the box body. After the cover body is covered on the box body, auxiliary fixation is generally needed through transparent glue, staples or the like, which brings certain inconvenience to disassembly and assembly. After the transparent adhesive tape and the staples fix the cover body and the box body, if the position or the number of the foods in the box body are required to be adjusted, the cover body is difficult to detach. On the other hand, when the consumer removes the upper cover, the consumer damages the cover body or the box body, and if the consumer cannot eat the food once, the damaged cover body or box body is inconvenient to operate when the consumer packs the food again.

Therefore, it is necessary to provide a food package box with a simple structure, a cover and a box body capable of being well matched and convenient to operate.

That is, the engaging portion 21 protrudes outside the cover 20, and the engaging portion 22 protrudes inside the cover 20. One side of the clamping part 21 is provided with a propping part 211, the other side of the clamping part 21 is provided with a limiting part 212, and a containing space for the box body 10 to extend in is formed between the limiting part 212 and the propping part 211. When the cover 20 is fastened to the case 10, the protruding portion 22 abuts against the outer side of the edge of the case 10, the abutting portion 211 abuts against the inner side of the edge of the case 10, and the limiting portion 212 abuts against the outer side of the edge of the case 10, so that the edge of the case 10 is elastically deformed within a predetermined range. The extension line of the abutting part 211 is also provided with the second guiding part 26, and the second guiding part 26 with an arc-shaped structure can guide the box body 10 to extend into the clamping part 21. It can be understood that the limiting portion 212 is used for limiting and supporting the box 10, and the abutting portion 211 and the protruding clamping portion 22 abut against the edge of the box 10 from the inner side and the outer side of the box 10, so that the edge of the box 10 is elastically deformed. The elastically deformed case 10 has a constant resetting tendency to react against the abutment 211 and the protruding portion 22, thereby forming a friction force to prevent the case 10 from being separated from the cover 20, so that the case 10 is firmly embedded in the cover 20 and is not easy to fall off. On the other hand, a plurality of clamping blocks 24 are further distributed in the cover 20, the cover 20 is buckled on the box 10 so that the clamping blocks 24 are propped against the outer side of the edge of the box 10, and the clamping blocks 24 are used for reinforcing the clamping between the box 10 and the cover 20. The snap-fit structure 210 further includes a positioning recess 28, and a positioning protrusion 23 is convexly disposed on the inner side of the cover 20 toward the direction of fastening with the box 10, and a space between the positioning protrusion 23 and the inner wall of the cover 20 forms the positioning recess 28. The positioning concave portion 28 is used for guiding the box body 10 to be buckled with the cover body 20, and the edge of the box body 10 is positioned in the positioning concave portion 28, so that the box body 10 can keep the first state. The first guide 231 on the positioning recess 28 can guide the case 10 to a proper mounting position so as to be better engaged with the cover 20. In addition, the positioning recess 28 can avoid the case 10 from being deformed inwards due to excessive deformation of the case 10 under the abutment of the protruding clamping part 22 and the clamping block 24, and the deformed case 10 may be separated from the protruding clamping part 22 and the clamping block 24, so that the case is easy to separate from the fixing structure. Namely, under the guiding limit of the positioning concave part 28, the box body 10 is not easy to deform, and the original state of the box body 10 can be kept as far as possible; and the positioning concave 28 enables the box body 10 and the cover body 20 to be more firmly embedded together. The food packaging box 100 has a simple structure, the box body 10 and the cover body 20 are firmly embedded, and the box body 10 and the cover body 20 are convenient to be buckled and disassembled.

The foregoing disclosure is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
