Description

Load-enhancing prefabricated packing box and assembly method thereof

The present invention relates to a packaging box, and more particularly, to form a support structure that can withstand a load even if the packaging box is located at the bottom when the packaging box is loaded, and has a structure that is easy to load while also having an adhesive means It relates to a load-reinforced prefabricated packaging box with a structure that can be assembled without using it at all.

In general, a packaging box is used to store and protect the product and to increase the value of the product. These packaging boxes are mainly made of paper, and are also made of various materials such as plastic.

These packaging boxes are used for packaging various items such as agricultural products, home appliances, beverage containers, various gift items, and pouch products containing liquid contents, and are applied to various fields.

Although the packaging box can be manufactured in many different ways depending on the type of product to be packaged, it is usually manufactured in the form of a box having a rectangular hexahedron shape, and the product is stored and distributed therein. Since it is made by folding a sheet of paper, it is advantageous for recycling as well as easy assembly and disassembly.

However, conventionally, adhesives, staplers, or tapes have been used to fix the wall part constituting the paper packaging box, but this complicates the assembly process when assembling the packaging box, and requires additional preparations for assembling the box. have.

In addition, when a paper packaging box is loaded, the box located at the bottom is subjected to a significant load and collapses, thereby causing a problem in that the product stored in the packaging box is damaged.

Therefore, there is a need to develop a packaging box of a new structure in which these problems are solved.
