Description

PACKAGING BOX FOR EASY ASSEMBLE}

The present invention relates to a box for easy assembly.

In general, a box for packaging an object or for storing an article is mostly used by folding paper, particularly thick corrugated paper, in various shapes for resource recycling and eco-friendliness.

The packaging box using such a cardboard or corrugated cardboard is foldable, light weight, easy to stack, convenient transportation and storage of goods, and the advantage of not easily damaging the internal goods to external shocks. have.

On the other hand, most of the packaging boxes are produced in a developed view during production, and then assembled into various three-dimensional shapes to store and package various items.

At this time, in the case of a relatively simple type of packaging box, the assembly time is relatively short due to its simple structure, but in the case of a complicated type of packaging box, the structure is complicated, and as a result, the assembly time is increased. The production time of the action box is continuously increasing.

On the other hand, as a related art, Korean Patent Registration No. 10-1546842 (Registration Date: August 18, 2015) discloses a'packaging box for disassembly and assembly'.

The Korean registered patent has the advantage of facilitating the assembly and disassembly of the packaging box by assembling a plurality of side plates provided with a square plate-shaped corrugated cardboard by means of a side plate connecting member, but connecting the side plates disposed at each corner. In the process of assembling the first, second and third and fourth side plates on the member, the assembly time is not only delayed, but also a plurality of side plate connecting members and the first, second and third and fourth side plates must be manufactured separately. There is a disadvantage that the manufacturing cost increases due to the increase of equipment.

Accordingly, the present invention has been devised in the above-mentioned background, and the object of the present invention is to shorten the manufacturing time by minimizing the adhesion process and the assembly process. It is to provide a box for easy assembly that can be lowered.

In addition, an object of the present invention is to provide an easy-to-assemble packaging box that can form a double-walled structure, both side walls, front side walls, and rear side walls during assembly to more reliably protect products accommodated inside from external impact.

The object of the present invention is not limited to this, and other objects not mentioned will be clearly understood by those skilled in the art from the following description.

In order to solve this problem, an embodiment of the present invention includes a central panel portion forming a bottom surface when assembled; Left and right panel portions connected to both sides of the central panel portion, folded to the upper side of the central panel portion to form both side walls of a double wall structure, and having binding grooves formed therein; And the front and rear panels connected to the front and rear of the central panel unit and folded to the upper side of the central panel unit during assembly to form a front wall and a rear wall of a double wall structure, and connected to both sides of the front and rear panels. It provides an easy-to-assemble packaging box comprising a; front and rear panel portion including a binding projection coupled to.

According to an embodiment of the present invention, it is possible to shorten the manufacturing time by minimizing the adhesion process and the assembly process, and has the effect of minimizing the manufacturing facilities and lowering the manufacturing cost by assembling a single developed view.

In addition, according to an embodiment of the present invention, when assembling, by forming both side walls, front side walls, and rear side walls of a double wall structure, there is an effect that the product accommodated inside can be more stably protected from external impact.

The effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.
