To provide a packaging box made of excellent polygons and to provide a box cover used for manufacturing the packaging box.

In general, fresh products such as fish and meat should be kept in a styrofoam box or wooden box for distribution. In particular, the styrofoam box is widely used because it has excellent heat insulation performance and can block moisture.

In the environment where food corruption is easy as in the summer, the refrigerant such as ice is placed inside the styrofoam box or the wooden box to keep the freshness of the product longer.

The packaging box of such a product is not simply used for display and storage of merchandise, but also functions to facilitate distribution by packing the merchandise in a predetermined unit. In recent years, since such a box is often shipped and delivered to a consumer, a box is made of a paper printed with a certain pattern or pattern, or a cover is put on a body made of styrofoam or the like to improve the appearance of the box Gift packaging boxes are made and sold.

Especially, in the case of gift packing boxes, in order to add a more luxurious image, polygonal boxes such as pentagons, hexagons, and octagons were used in addition to the quadrangle. When the box cover was put on the box body, A box block for supporting a box such as a column block, a support block, etc. was made and the box block was connected to make a box for a gift packing made of a polygon such as an octagonal box having a certain thickness on the wall surface.

In such a case, the more the number of the box blocks constituting the polygonal gift packing box is, the more the connection is difficult and the durability is weak. Particularly, it has been difficult to connect the pillar blocks constituting the wall of the box with the bottom surface of the box. In this way, it takes a long time to make a polygonal box for packaging having a certain thickness on the wall surface, and the labor cost and the cost are wasted accordingly.

In addition, in order to add a luxurious image of the product, when a part of the wall of the packing box is made to be a leg so that the bottom of the packing box does not touch the ground, The cost and labor increase, and not only the process efficiency is low but also the durability is low, so that it is difficult to manufacture.

That is, since the packaging box has a structure in which the bottom surface of the box is coupled to a portion of the box wall that is not the lowermost end of the box to form a so-called box leg, the durability of the box becomes low, And there are many problems such as inefficiency of work process and manpower consumption.

It is difficult to manufacture a packaging box made of a polygon. Especially, in the case of a packaging box having a polygonal shape of five angles, six angles, eight angles and twelve angles, the manufacturing process is complicated and it is difficult to simplify the molding process. And the durability of the packaging box deteriorates with the increase in the number of the packaging boxes.

Further, since the box cover is coupled to the box body using an adhesive, there is a problem that it is difficult to separate the box cover from the box body after using the packaging box. That is, even if the box cover is dirty, the box cover can not be removed even if the box body is not damaged, so that the box body can not be reused.
