Description

Corrugated paper box

Technical Field

The invention belongs to the technical field of packaging boxes, and particularly relates to a corrugated carton.

Background

Cartons are the most widely used packaging articles in modern society. Cartons are devices used to temporarily wrap products during their production, transport, storage and sale in order to protect and decorate them for good use. The paper box can be used for packaging small articles such as clothes, food and the like, and can also be used for packaging large articles such as televisions, refrigerators and the like, the application range is wide, and the paper box is deeply favored by people due to low price and good performance. The corrugated case is one kind of packing case, and has the features of low packing cost, effective use of resource, easy reuse, no environmental pollution, low cost, etc. and is used in packing various products. But the present corrugated box is mostly a box and a top cap, simple structure, and intensity is low to often when loading some article that can not receive extrusion, collision, often intensity is not enough, and the carton is easily extruded deformation or damage in the transportation, can influence the inside article of carton, causes the damage of goods, brings unnecessary economic loss.

Patent documents: a high strength corrugated box of application No.: 201410412733.6

In the patent documents, a certain amount of reinforcing ribs are added in the box body, paired small holes are punched in the box body, and the reinforcing ribs are fixed by the binding bands penetrating through the small holes, so that the compressive strength of the box body is increased; but fix the strengthening rib through the form of ligature and increased working strength, reduced work efficiency, simultaneously, the ligature area makes the packing box pleasing to the eye and the ligature effect is limited.
