Description

Agricultural products packing box self-assembly

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a packaging bag for assembled agricultural and marine products, and more particularly, to a packaging bag for a prefabricated agricultural and marine products packaging, And the coating member is integrally formed with the body on the inner side, the inner side, and the outer side in the bending part made of the resin, and when stored and transported, it occupies a small storage and transportation area. In use, The present invention relates to a prefabricated agricultural and marine products packaging box which can be packed with a variety of agricultural and marine products such as marine products, agricultural products and fruit even if the bending portion is repeatedly used.

In general, a box for packing aquatic products will use a body with a clogged inner slope so that most of the boxes can be packed with wood or synthetic foam, plastic, or styrofoam. Since ice or ice packs are packed together for the purpose of improving preservability, a lot of moisture is generated inside. Therefore, in order to prevent the water from being discharged to the outside during the movement, it is common to wrap the plastic in the inside.

However, since these aquatic packing boxes are formed in a square shape in advance, they take up a large volume until they are used after production, and thus require a large space for storing the packaging boxes. The productivity is so low that non-economic defects occur.

Also. These aquatic products packaging boxes are difficult to dispose of after being packed, which causes a problem of polluting the environment.

In order to prevent the defects of such a conventional aquatic packing box and to make it possible to use a corrugated cardboard box for packing agricultural products, the inside of the box vulnerable to moisture is prevented from being deformed into moisture by coating, However, it is possible to solve the disadvantage of being susceptible to a certain degree of moisture by the coating, but it is impossible to prevent the water from being deformed by water generated after inserting ice, and thus it is not applicable to aquatic products.

On the other hand, Korean Patent Laid-Open Publication No. 2012-0007029 (published on Jan. 19, 2012) is made up of an inflatable material. In the blank for a box molded in a smooth shape in the initial molding step, folded portions constituting the hinges are formed And the tooling forming the shape of the blank is provided such that the thickness of the expanded material is less than the thickness of the majority of the blank, the area of small thickness being provided by the edge portions formed in the direction of the respective folded- And forms the box by forming the hinges by reducing the thickness of the blank without removing the inflating material by continuously applying pressure along the area where the folds are formed.

However, since the film provided as a film for maintaining the watertightness can be coated with an adhesive such as a urethane layer, the urethane layer may be blown off due to the rise and fall of the temperature of the box, And it is difficult to assemble the box body in a separated state since the box body is fixed so as to maintain the box shape using the clip portion. When the clip portion is detached, it is difficult to assemble and prepare it again, Which is very difficult to do.
