The present invention relates to a paper packaging box made by folding and assembling a single cardboard several times, and more specifically, by a simple assembly structure, it is possible to maintain a solid packaging state against external impacts, thereby minimizing damage to contents and carrying and The present invention relates to a prefabricated packaging box with improved storage convenience.

In general, packaging boxes for packing agricultural and marine products, foods, and gifts should be easy to handle and easy to store and transport. In recent years, lightweight cardboard is used to maintain high strength to prevent damage to contents. Is being manufactured.

Most of these paper packaging boxes are manufactured using corrugated cardboard. At this time, the corrugated cardboard is 1/3 lighter than the wooden crates and the volume is reduced by 30-40%, so the loading efficiency of cargo is high. It is advantageous.

Such packaging boxes have been proposed in various forms. For example, in Korean Patent Laid-Open Publication No. 1999-64381, an upper portion is opened, and is formed in a square or rectangular shape, and forms a through hole for smoothly distributing air on each surface. In addition, an easy-to-draw small box is disclosed, which comprises a pull-out handle integrally formed at the upper center of the left and right side plates of the small box, and Utility Model No. 20-234321 discloses a rectangular bottom plate. It forms a trapezoidal through hole on all sides and forms a front / rear plate and a left / right plate of the bottom plate bent by a predetermined bending line, and an insertion protrusion inserted into the through hole on one side, and a bent plate of the auxiliary plate on the other side. One auxiliary plate, a reinforcement plate which can be bent by a left / right side plate on one side of the auxiliary plate, a defect groove on one side of the reinforcement plate, and a reinforcement plate and a / A packaging box is disclosed which extends through a face plate, and in Japanese Unexamined Patent Publication No. 86-9724, a side plate of a box is composed of an inner and an outer plate, and a supporting piece is formed at both ends of the inner and outer plates. Disclosed is a strawberry packaging box in which a support piece is formed on a corner of a container.

However, the pre-applied packaging boxes are not only inferior in the storage of the contents but also inconvenient to check the contents, and inconveniently need to open the boxes to check the contents, and frequently open and assemble the paper boxes. In this case, the open part is torn, causing a problem of lowering the image of the product.

In addition, there is a difficulty in distribution and storage due to the impossibility of stacking in the state in which the contents are stored, which causes a problem that requires a relatively large space during distribution and storage.
