A heavy-weight packing case for packing a heavy object placed on the lower packing case, which comprises a lower packing case in which a fork insertion space of a forklift is formed and an upper packing case which is used by being stacked on the lower packing case. ，
An extension is formed at a position corresponding to the column on the upper part of the upper packing case to reach the lower end of the column, and connecting tool insertion holes are formed in the extension and the column, respectively, and between the extension and the column. The lower packing case and the upper packing case are connected by connecting with the connecting tool inserted into the connecting tool insertion hole, thereby forming a heavy-weight packaging case.

[0005]

The heavy-weight packing case according to the present invention is a packing in which heavy goods are packed by connecting a lower packing case in which a forklift fork-lifting space is formed by a pillar and an upper packing case to be integrated with the lower packing case. The case is configured to be individually transportable using a forklift. The lower packing case and the upper packing case are connected to each other by forming a connecting tool insertion hole in a support provided in the lower packing case, and extending a position corresponding to the connecting tool insertion hole and the supporting post of the upper packing case to the lower end of the support pillar. This is done by aligning the connector insertion hole formed in the extended portion and inserting the connector into this. Therefore, the lower packaging case does not have a protruding portion like the flap required in the conventional configuration, and work with poor workability to raise and fix the flap is not necessary, and the material area of the bottom plate and the number of processing steps are reduced. Therefore, the cost can be reduced, and the inventory space can be reduced because the lower packaging case has no protruding portion.
