Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging boxes, in particular to a high-pressure-resistant and fast-folding paper packaging box. Background Art

[0002] Paper packaging boxes, also known as cartons, are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper (color and feel) produced by different manufacturers is also different.

[0003] In today's society, paper packaging boxes are often used to pack objects. However, in actual applications, existing paper packaging boxes have insufficient protection resistance and are easily subjected to pressure from the top and sides. In addition, there is no good protection effect on the corners, making the paper packaging boxes easy to be damaged, thereby affecting the safe storage of the objects inside and having poor practicality.

[0004] Prior art CN215156569U is a paper packaging box with a reinforced structure. Through the split design of the paper packaging box body and the inner reinforced box body, the first frame-shaped buffer block and the second frame-shaped buffer block made of cotton blocks are provided between the paper packaging box body and the inner reinforced box body, which can effectively buffer the lateral impact force on the box body. At the same time, the design of the reinforced edge and frame-shaped reinforcement strips enhances the strength of the inner corners and side walls of the paper packaging box body in the inner reinforced box body, and the top reinforcement strip provided at the top of the inner reinforced box body can provide a certain support force when the paper cover is covered, thereby enhancing the compression resistance of the top of the box body, thereby solving the above technical problems. However, the above device is not reusable, and the cardboard box as a whole is not easy to disassemble and install. When the empty box is stored, it cannot be flexibly disassembled and stacked. The batch application in the process of commodity transportation will greatly increase the cost of logistics transportation; therefore, it does not meet the existing needs. In this regard, we propose a high-pressure-resistant and fast-folding paper packaging box. Utility Model Content
