Description

PAPER BOX FOR IMPROVING HARDNESS}

The present invention relates to a paper box, and more specifically, the bottom portion is made of a double, and the side portion and the cover fixing surface firmly supports the cover surface to improve the strength to prevent the storage of the article and deformation due to external pressure, etc. The storage is made stable and reliability is secured, and it is related to an economical paper box because the assembly is made solid without using an adhesive.

Today, boxes made of paper are lighter and less fragile than boxes made of wood or plastic, which is convenient for logistics and transportation, and courier service is available due to possible problems such as deforestation or environmental problems that arise due to the use of plastic materials. It is used in various forms such as boxes, gift boxes, organizers and shoe boxes.

A conventional paper box is assembled after cutting papers such as corrugated cardboard, and extends from the side to form a bottom portion, a side portion extending from the bottom portion to be bent vertically to form a predetermined space, and a space of the side portion. It includes a cover portion formed integrally or manufactured separately.

The above-described paper box is moved or stored in a state where other articles or paper boxes are stacked on top, in which case there is a problem in that the shape of the box located at the bottom is deformed or damaged due to the pressure from the top. In addition, there is a problem that the shape of the paper box is deformed because the bottom surface is moved down due to the weight of the article stored in the paper box. In order to solve this problem, a method of using a more rigid material as a fabric of the paper box or adding a reinforcing member separately manufactured to the paper box is used according to the load of the object to be stored.

However, solving the strength problem of the paper box by changing the fabric of the paper box as described above is structurally limited, there is a problem that the cost of the fabric change is further added. In addition, the addition of the reinforcing member to the paper box, there is an inefficient problem, such as the increase in cost and waste of time by adding a plurality of work processes for the formation and assembly of the reinforcing member.

On the other hand, the conventional paper box is structurally in contact with the portion of the surface and the overlapping portion of the fabric overlap is weak because the use of a separate adhesive to add the firmness of the paper box. Therefore, there is a problem in that economics are inferior as a process and a cost for bonding the paper box are added.

The present invention is to solve the above-mentioned problems, in particular, the bottom portion is made of a double, the side portion is firmly supporting the cover surface, the cover fixing surface is formed in a size corresponding to the side portion due to the improvement of the overall strength It is an object of the present invention to provide a paper box in which the storage of the article and deformation due to external pressure are prevented and the storage of the article is stable.

Paper box 1 according to an embodiment of the present invention includes the first to fourth fixing blades (200a to 200d) on the side portion 200, forming a third side 230 and the fourth side 240 The inner side surfaces 230b and 240b and the first and second insertion surfaces 250 and 260 are inserted between the first side 210 and the second side 220, respectively, so as to be assembled without using an adhesive. This can be done solidly. In addition, the coupling protrusions 234a and 244a formed on the inner surfaces 230b and 240b are respectively formed in the coupling grooves 120a and 130a of the first and second reinforcement portions 120 and 130 constituting the bottom portion 100. Insertion and fixation make the fastening more secure. At this time, the cover fixing surface 320 has the same size as the second side surface 220, the end or the side edge 321 inserted between the second side surface 220 and the third and fourth fixing blades (200c, 200d) is Since the cover fixing surface 320 is prevented from being separated so as to be close to the bottom surface 110, a separate adhesive may not be interposed for sealing the paper box 1. Therefore, the paper box 1 can be omitted because the fastening is secured only by assembling, the separate process for interposing the adhesive, the cost is reduced and economical.

The present invention is not limited to the above specific preferred embodiments, and any person skilled in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes are within the scope of the claims.
