It is about.

In general, the packaging process of the article is a common form of weaving method in which the article to be packaged on top of the pallet, after attaching a plurality of boards are attached to the wall plate, and the ceiling plate is covered with a plurality of plates on top of the wall boards This packaging box is usually made of wood.

However, once the packaging box made of wood can not be used again for the purpose of packing the goods once used, not only can not be used repeatedly, but also the production period becomes longer because the materials must be connected one by one. In the packaging of heavy materials, many members are required to support the weight, and therefore, a work space for handling a large number of members is required, as well as difficult packaging stability.

In addition, the manufacture of wooden packaging boxes is not only a source of deforestation, but also a disposal method after incineration, and there is no proper treatment other than incineration, and in this case, environmental problems due to incineration are emerging as a problem that cannot be overlooked. .

Such steel type packing box is composed of 6 plates and takes 24 frames, so waste of frame materials is severe and, for example, square pipes are usually used without consideration of the volume and load of the frame materials to secure the welding surface of the frame materials. This expensive and difficult to match the fastening hole of each plate when the frame is deformed during the welding process.

In addition, each plate fixed by welding is difficult to convert due to the lack of compatibility according to the volume and load of the packaged goods, and it is reused only for packaging of the same size even when it is recovered, and the reuse rate is extremely low because it is difficult to replace damaged parts. In addition, when reuse is unnecessary, there are many problems in handling and storage due to difficulty in disassembling the plates.

Thus, the present invention was devised to solve the above-mentioned problems, and the four plates of the front and rear plates and the left and right plates of the six plates consisting of a pallet and a ceiling plate, a front and back plate, and a left and right plate of the packing box and the pallet. It is possible to easily separate or assemble by replacing wall plates (W) with pillars placed on the corners between the ceilings and the spaces between the pillars, and to improve the structure of pallets under concentrated loads. The purpose of the present invention is to provide a packaging box that distributes concentrated loads and facilitates assembly between members, thereby reducing assembly time during assembly, securing stability of packaging, and increasing reuse rate.

The present invention for achieving the object of the bar, the pallet to which the goods to be packaged is mounted, a pillar member standing in the vertical direction in the corner portion of the pallet, and an auxiliary pillar member standing in the vertical direction between the pillar member, It is composed of a connecting member bowling in the width direction between the pillar and the auxiliary pillar, a ceiling plate bowling on the upper portion of the pillar and the auxiliary pillar, and a wall plate mounted on the front and side of the pillar.
