Moisture-proof and water-proof packaging carton

Abstract

The invention relates to a moisture-proof and water-proof packaging carton. The moisture-proof and water-proof packaging carton comprises a carton body, a damping support seat and a water-proof structure, wherein the damping support seat is installed at the bottom of the inner side of the carton body, the water-proof structure is installed at the middle part of the outer side of the carton body, and the damping support seat comprises a bearing plate, a telescopic rod, a jacking air bag, a communicating pipe, an air storage bag, a compression frame and a locking bolt; and the water-proof structure comprises a rotating ring, a rotating roller, a rotating gear ring, a driven gear ring, a locating roller and a water-proof film. According to the invention, the damping support seat is arranged in the carton body, the function of reducing vibration borne by goods in a transportation process is realized, and in addition, the height of the upper end surface of the damping support seat can be adjusted according to the actual sizes of the goods so as to change the size of a storage space, so that the situation of low stability in the transportation process due to the fact that the sizes of goods are not matched with the size of the packaging carton is avoided.

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, and plastic box packaging, carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. It is widely used in product sales packaging and transportation packaging. [0003] Although the packaging carton has many of the above advantages, the following problems still commonly exist in its actual use: [0004] (1) Due to the limitation of the characteristics of the paper, the waterproof performance of the packaging ...

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
