Description

Easy-to-assemble paper buffer protectors

The invention relates to the technical field of packaging, in particular to an easy-to-assemble paper buffer protector.

With the development of network technology, the growth of e-commerce is becoming more and more prosperous; e-commerce operators must properly pack the goods in packing boxes before handing over the goods to the freight forwarders. Bags, ... etc. (hereinafter collectively referred to as packaging boxes), and then cover the cover of the packaging box and then stick it with adhesive tape to seal it; other postal services are roughly the same. The general packing box structure is to form a three-dimensional rectangular packing box by bending according to the folding line formed on the cardboard in advance, and then glue and fix the three-dimensional packing box with glue.

In order to prevent the goods packed in the packing box from shaking or being damaged by external shocks during transportation and handling, some goods must be equipped with protective parts before packing them into the packing case; the protective parts are traditionally Styrofoam foam material is used as the main product, and the Styrofoam material is light, elastic and impact-resistant to provide good protection for goods. However, due to the disadvantages of Styrofoam material that it is not environmentally friendly and bulky, before the goods are packaged, a huge warehouse space must be prepared to store the Styrofoam foam material as a protective part.

In order to overcome the problem of using styrofoam foam as a protective part, which is not environmentally friendly and takes up too much space, there are many other product protection devices made of paper on the market, but the known paper cushioning materials are more expensive than traditional protective materials. Cushioning materials made of Lilong foam materials are much more expensive, because the structure is more complicated, and glue or double-sided tape must be used to fix them after assembly, so it is difficult to assemble and there are problems such as high cost; moreover, if Manufacturers of paper cushioning materials are required to assemble them in a three-dimensional shape during production, which will take up a lot of space during transportation and storage. It is not in line with economic benefits, and it is extremely troublesome for the merchants.

The purpose of the present invention is to improve on the basis of the known paper packing box structure to form a paper protective member, so that the present invention can be flattened to reduce transportation and storage space when not in use, and can be used when it is to be used. The protective part can be quickly formed by simple assembly without the use of glue or double-sided tape. It has a simple structure, low cost, and environmental protection. Compared with traditional polystyrene foam materials, it has better characteristics.
