The present invention relates to a paper packaging box, and more particularly to a paper packaging box to minimize the damage to the contents by maintaining a robust packaging state against external impact and to enhance the convenience of transport and storage.

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. 1999-64581, an upper portion is opened, and is formed in a square or a 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 in the upper center of the left and right side plates of the small box, and Utility Model No. 20-264621 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 which are bent by a predetermined bending line, and an insertion protrusion inserted into the through hole on one side thereof, and a bending plate of an auxiliary plate on the other side thereof. 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.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a paper box that is structurally robust by a simple method of folding a single paper carton along a fold line.

Another object of the present invention is to provide a paper packaging box that can be laminated while enabling the safe storage of the contents, such as agricultural products that are easily damaged by external impacts, to increase the convenience of distribution and transportation.

The paper packaging box according to the present invention for realizing the above object is made of a first side wall formed with a hole for the handle and a trapezoidal first bottom which is folded at right angles by a horizontal fold line while extending from the lower end of the first side wall.

It is characterized by being configured to include a piece.

As a preferable feature of the present invention, the first, second, third, and fourth sidewalls form outer walls, and each of the outer wall portions connected by the vertical fold lines and the upper side ends of the outer wall portions, respectively, by horizontal fold lines. It consists of an inner wall part which is folded 180 degrees and located inside.

In another preferred aspect of the present invention, the second and fourth bottoms are provided in a rectangular shape, respectively, and are provided with staggered fittings formed at the centers of the edge surfaces in opposite directions.

As another preferable feature of the present invention, the first, second, third and fourth plate members are paper panels having a honeycomb structure.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in this specification and claims are not to be interpreted in a conventional and dictionary sense, and the inventors may appropriately define the concept of terms in order to best describe their own invention.
