A moisture-proof and waterproof packaging carton

Abstract

The invention relates to a moisture-proof and waterproof packaging carton, comprising a box body, a shock-absorbing support and a waterproof structure. The supporting plate, the telescopic rod, the lifting air bag, the connecting pipe, the storage air bag, the compression frame and the locking bolt. The waterproof structure includes a rotating ring, a rotating roller, a rotating gear ring, a driven gear ring, a positioning roller and a waterproof membrane. The invention realizes the function of reducing the vibration magnitude of the goods during transportation by arranging the shock-absorbing support in the box, and also can adjust the height of the upper end surface of the shock-absorbing support according to the actual size of the goods to change the storage The size of the space can avoid the situation of poor stability during transportation due to the mismatch between the size of the goods and the size of the packaging carton.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a moisture-proof and waterproof packaging carton. Background technique [0002] Carton packaging refers to the packaging of products in paper boxes in order to protect products, facilitate storage and transportation, and promote sales during the circulation process. Carton packaging is the most widely used packaging method. Different from wooden box packaging, woven bag packaging, cloth bag packaging, plastic box packaging, carton packaging has the characteristics of easy access to materials, light weight, easy printing, easy design and molding, and low cost, and is widely used in sales packaging and transportation packaging of goods. [0003] Although there are many advantages of the packaging carton, the following problems still exist in its actual use: [0004] (1) Due to the limitation of the characteristics of paper, the waterproof performance of the packaging carton is poor.

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the limitation of the characteristics of the paper, the waterproof performance of the packaging carton is poor. When the packaging carton is in contact with liquid such as water, it will be soaked quickly, and the liquid will enter the inside of the packaging carton, causing damage to the goods in the packaging carton, resulting in unsightly recoverable loss;

[0005] (2) The size of the packaging carton is limited, and often cannot completely match the actual size of the goods. If the gap between the goods and the carton is large, the goods will shake during transportation, and the stability during transportation is poor, and it is easy to cause collisions. and damaged;

[0006] (3) If cushioning foam is used to fill the gap between the carton and the goods, the transportation stability of the goods can be improved to a certain extent, but the cushioning foam is mostly a one-time use product, which is not conducive to environmental protection, and needs to be filled according to the gap The actual size of the cushion foam of the corresponding size is selected, and the production process is more complicated
