Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboard, in particular to a corrugated paperboard with a buffer structure. Background Art

[0002] Corrugated cardboard is also called corrugated cardboard. It is made of at least one layer of corrugated paper and one layer of boxboard (also called boxboard) and has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons and other packaging materials for fragile goods. It is mainly made of traditional straw pulp and waste paper through pulping to make a raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

[0003] However, when the existing corrugated cardboard is made into a packaging box to package items, when it is hit by an external object, the impact force can easily penetrate the corrugated cardboard and directly act on the items in the box, or even be directly pierced, thereby causing irreversible damage to the items inside the box.

[0004] Therefore, it is very necessary to invent a corrugated board with a buffer structure. Utility Model Content

[0006] Preferably, the concave cavity of the arc-shaped plate 1 and the concave cavity of the convex paperboard 1 form a buffer cavity 1;

[0007] Preferably, the concave cavity of the second arc-shaped plate and the concave cavity of the second convex paperboard form a second buffer cavity.

[0008] Preferably, the composition structure of the convex paperboard 1 is the same as that of the convex paperboard 2; the convex paperboard 1 includes an outer panel and an inner panel, and a honeycomb core panel is fixedly bonded between the outer panel and the inner panel; the arc plate 1 is bonded and fixed to the inner panel of the convex paperboard 1; the arc plate 2 is fixedly bonded to the inner panel of the convex paperboard 2.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] The overall arrangement of the utility model can buffer the impact force when encountering an impact from an external object during the process of making a box to package articles for use. At the same time, during the buffering process, the object and the impact force of the object can be resisted and isolated. In this way, not only can the impact force be prevented from directly penetrating the corrugated cardboard to act on the article, but also the object can be prevented from directly piercing the corrugated cardboard, thereby effectively ensuring the safety of the article.
