Description

TECHNICAL FIELD

[0001] The utility model relates to a meal box field, concretely is a combined paper meal box. BACKGROUND

[0002] Most of the meal boxes are made of plastic materials, which are not environmentally friendly. With the progress of the times, people's environmental awareness is constantly enhanced. In order to reduce the impact of plastic meal boxes on the environment, people have invented some environmentally friendly meal boxes, including paper pulp meal boxes. However, the existing paper pulp meal boxes are all single-layer box bodies, which have relatively high overall temperature during use, and are easy to burn when serving and taking. Moreover, the meal boxes made of paper pulp need to add too much coagulant material, which leads to the meal boxes being not environmentally friendly. Therefore, the technical personnel in the field provide a combined paper meal box to solve the problems raised in the above background technology. SUMMARY

[0003] The utility model aims at providing a combined paper meal box to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A combined paper meal box comprises an outer hard box body made of paper and an inner partition box body, the inner partition box body is arranged inside the outer hard box body, and the inner partition box body has a middle grid in the middle part for partitioning the inner partition box body into a plurality of compartments.

[0006] Further, the outer hard box body has an outer edge protrusion on the upper periphery.

[0007] Further, the inner partition box body is tightly attached to the inner bottom of the outer hard box body, and the side wall of the inner partition box body is tightly attached to the inner side wall of the outer hard box body.

[0008] Further, the inner partition box body is tightly attached to the inner bottom of the outer hard box body, and the side wall of the inner partition box body is tightly attached to the inner side wall of the outer hard box body.

[0009] The inner partition box body comprises a pure paper layer, a first waterproof layer coated on the periphery and the bottom of the pure paper layer, and a first sealing glue layer coated on the periphery of the first waterproof layer; the outer hard box body comprises an outer layer of hard paper layer, a second waterproof layer coated on the upper part and the inner wall of the outer layer of hard paper layer, and a second sealing glue layer coated on the upper part of the second waterproof layer.

[0010] The first sealing glue layer and the second sealing glue layer adopt food-grade hot sealing glue or cold sealing glue.

[0011] The outer layer of hard paper layer and the pure paper layer are integrally pressed by pure paper material.

[0012] This invention creates a new type of lunchbox by combining a double-layered inner layer with a cavity and an outer layer without a cavity. This provides insulation and is more environmentally friendly than existing lunchboxes made of pulp or plastic materials. Furthermore, by using a first and second sealing layer made of food-grade heat-sealing or cold-sealing adhesive, the two layers can be quickly bonded together, facilitating pressing and assembly and improving efficiency.

Outer rigid paper layer; 203. Second waterproof layer; 204. Second sealing layer. Detailed Implementation

[0017] Please see Figs. 1-3 In this embodiment of the present invention, a combined paper lunch box includes an outer rigid box body 2 and an inner divided box body 1 disposed inside the outer rigid box body 2. The inner divided box body 1 has a middle grid 101 in the middle that divides it into several compartments.

[0018] By adopting the above technical solution, the lunch box is made into a double layer, with one layer having a cavity and the other without a cavity, and then combined to form a new lunch box, which is more environmentally friendly than the existing lunch boxes made of pulp or plastic materials.

[0019] The outer rigid box body 2 has an outer edge protrusion 201 on its upper periphery, which makes it convenient to take out the lunch box.

[0020] The inner partition box 1 has its bottom tightly attached to the inner bottom of the outer rigid box 2, and its sidewalls are tightly attached to the inner sidewalls of the outer rigid box 2. The inner partition box 1 and the outer rigid box 2 are bonded together with an adhesive layer.

[0021] The inner partition box 1 has its bottom tightly attached to the inner bottom of the outer rigid box 2, with a gap between the side wall of the inner partition box 1 and the inner side wall of the outer rigid box 2. The bottom of the inner partition box 1 and the inner bottom of the outer rigid box 2 are glued together with an adhesive layer. The gap between the side walls provides better heat insulation for the double-layered lunchbox, making it less likely for people to get burned when taking the lunchbox through the outer side wall of the outer rigid box 2.

[0022] The inner split box body 1 comprises a pure paper layer 104, a first waterproof layer 103 coated on the periphery and bottom of the pure paper layer 104, and a first sealing glue layer 102 coated on the periphery of the first waterproof layer 103, and the outer hard box body 2 comprises an outer layer hard paper layer 202, a second waterproof layer 203 coated on the upper side and inner wall of the outer layer hard paper layer 202, and a second sealing glue layer 204 coated on the upper side of the second waterproof layer 203.

[0023] The first sealing glue layer 102 and the second sealing glue layer 204 are made of food-grade hot sealing glue or cold sealing glue.

[0024] In the above technical solution, the first waterproof layer 103 and the second waterproof layer 203 can effectively prevent water penetration of the meal box, and by setting the first sealing glue layer 102 and the second sealing glue layer 204 made of food-grade hot sealing glue or cold sealing glue, the two can be quickly pasted together, facilitating the pressing and combining operation, and improving the efficiency.

[0025] The outer layer hard paper layer 202 and the pure paper layer 104 are integrally pressed by pure paper material, meeting the environmental protection requirements of the meal box.

[0026] The working principle of the utility model is: during processing, the outer hard box body 2 and the inner split box body 1 are pressed by a mold, and then the waterproof layer and the sealing glue layer are coated, during combination, the mold matched with the meal box is pressed, the cold sealing glue is directly pressed and combined, the hot sealing glue is heated and pressed, the rapid combination production can be realized, and the efficiency is improved.

[0027] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
