Damp-proof packaging carton with internal supporting structures

Abstract

The invention relates to the technical field of packaging cartons, and particularly discloses a damp-proof packaging carton with internal supporting structures. The damp-proof packaging carton comprises a box body. Upper box covers are correspondingly arranged on the four side edges of the upper end of the box body, transverse supporting plates are arranged on the transverse inner side walls of the upper end of the box body, longitudinal supporting plates are arranged on the longitudinal inner side walls of the upper end of the box body, damp-proof supporting plates are arranged at the positions, under the transverse supporting plates, of the bottom end of the inner side of the box body, and slots are formed in the sides, on the longitudinal supporting plates, of the inner side wall of thebox body. As the transverse supporting plates and the longitudinal supporting plates which are arranged rectangularly are additionally arranged at the upper end in the box body, a rectangular supporting assembly is conveniently formed at the upper end in the box body, meanwhile, the bottom of the box body is supported through the overturning type damp-proof supporting plates, the stability of thebottom end in the box body and the bearing force of the bottom can be conveniently improved, the internal supporting structures of the box body are all made of wood, the cost is low, the operation iseasy and convenient, the supporting effect is good, and the stability of the box body is high.

Description

technical field [0001] The invention relates to the technical field of packaging cartons, in particular to a moisture-proof packaging carton with an internal support structure. Background technique [0002] 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. As an indispensable part of modern logistics, packaging cartons are responsible for packaging, protecting products, and beautiful appearance. The important responsibility of the packaging carton, the physical performance index of the packaging carton has become the basis for its quality evaluation. The packaging carton not only plays a role in protecting the product during the specific use process, but also can print exquisite advertisements outside the packaging carton. Due to its manufacturing cost Low, the use effect is good, and it has been widely used in the process of product sa...

Problems solved by technology

[0003] However, when the existing packaging cartons are transporting and storing articles, because the cartons do not have a supporting structure inside, the cartons will be deformed when they are bumped or squeezed by the outside world, and in severe cases, the stored articles in the cartons will be damaged. The moisture-proof performance of the packaging cartons is not perfect, and when the items are stored for a long time, it will affect the service life of the cartons
