Description

Easy-to-assemble paper buffer protector

【Technical field】

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

【Background technique】

With the development of network technology, the growth of e-commerce has become increasingly prosperous; e-commerce operators must properly package the goods in boxes before they are delivered by freight operators. ﹑… etc. (hereinafter collectively referred to as the packing box), then cover the cover of the packing box and then stick it with tape to seal it; the same is true for other postal services. The general packing box structure is to bend and form a three-dimensional rectangular packing box according to the folding line formed on the paper board in advance, and then glue and fix the three-dimensional packing box with adhesive.

As shown in FIG. 1 and FIG. 2, a general packing box structure has a main board A, and the same side of the main board A can be bent to form a first side plate A1, a second side plate A2, a third side plate A3 and The fourth side plate A4, the same other side can be bent to form the fifth side plate A5, the sixth side plate A6, the seventh side plate A7 and the eighth side plate A8 in sequence, and the first side plate A1 and the The fifth side plate A5 corresponds to the second side plate A2 corresponds to the sixth side plate A6, the third side plate A3 corresponds to the seventh side plate A7, and the fourth side plate A4 corresponds to the eighth side plate A8 , and one end of the main board A forms a protruding plate A9; with this structure, a three-dimensional rectangular packing box can be formed after bending according to the fold line (the dotted line as shown in Figure 1), and then the protruding plate A9 is coated with glue after Adhere the protruding plate A9 to the other end of the main board A to fix the three-dimensional packaging box.

In order to prevent the goods packed in the packing box from being damaged by shaking or being impacted by external force during transportation and handling, some goods must be equipped with protective parts before being packed into the packing box; the protective parts are traditionally The bulk is made of Styrofoam foam material, and the Styrofoam material is light, elastic, and impact-resistant to provide good protection for goods. However, due to the disadvantages of styrofoam material, which is not environmentally friendly and bulky, before packaging the goods, a huge warehouse space must be prepared to store the styrofoam material as a protective piece.

In order to overcome the problems of using styrofoam foam material as a protective element, which is not environmentally friendly and takes up too much space, many paper-made goods protection devices are provided on the market, but the known paper-made buffer materials are more The cushioning material made of Styrofoam foam material is much more expensive, because the structure is more complicated, and it needs to be glued and fixed with adhesive or double-sided tape after the assembly is completed, so it is not easy to assemble and there are problems such as high cost; , If the paper buffer material manufacturer is required to assemble it in a three-dimensional shape during production, it will occupy a lot of space during transportation and storage, which is extremely uneconomical and causes great trouble for the manufacturer.
