Problems solved by technology

[0003] The structure of the above-mentioned lunch box can meet the basic function of loading items, but in the production process, the space between the pressing surface and the box body is formed by direct folding, and the folding position is usually judged by the operator based on experience. Not only is the position of the folding line unstable, but also after the folding is performed on the basis of the same material and the same thickness of the box body, the lower pressing edge will generate a large restoring force, making it difficult to shape the shape of the folding

Abstract

The invention provides an edge-folded corner-wrapped lunch box and a lunch box using method. The lunch box comprises an inner box body, a containing groove is formed in the inner box body, a box opening is formed in the inner box body, a turnover piece is arranged on the inner box body, the turnover piece is located at the box opening, a turnover line is arranged at a turnover point between the turnover piece and the inner box body, and the turnover line is formed by linearly arranging a plurality of through grooves penetrating through the inner box body at intervals. The restoring force of the turnover piece is greatly reduced, and the folding and shaping difficulty is greatly reduced. In addition, the inner box body can be formed by stirring and mixing starch, plant fibers, a waterproof agent and a release agent to obtain pug, and then performing high-temperature compression molding on the pug and lining paper together. The paper material is biodegradable and has certain environmental protection performance.

Description

technical field [0001] The invention relates to a lunch box, in particular to a folded-edge and corner-wrapped lunch box and a method for using the lunch box.
