The present invention relates to an assembling container and an assembling method of the assembling container, and more particularly, an assembling container that can effectively prevent the swelling of the body while having a small number of parts and can be efficiently assembled. And an assembling method of the assembling container.

Conventionally, assemblable containers have been used for transporting irregular shaped objects such as liquids, powders and granules, or shaped objects.
This assembled container has a pallet with a forklift insertion slot so that it can be transported by a forklift, and a cylinder that is assembled to the pallet, and is in a space constituted by the upper surface of the pallet and the inner peripheral surface of the cylinder. In some cases, the pallet is stored, and in some cases, the cylinder is covered, and then the pallet is conveyed by a forklift.

Patent Documents 1 and 2 disclose examples of such a prefabricated container.
According to Patent Document 1, an assembling container for storing a synthetic rubber, a natural rubber bale (cuboid large solid body) packaged article, etc. is disclosed, and includes a pallet, a pair of short side plates, and a pair of long side plates. The short side plate consists of a side plate panel with an upper frame, an intermediate frame, a lower frame and a short side column attached to the outer surface, while the long side plate is similarly upper on the outer surface. It consists of a side plate panel to which a frame, an intermediate frame, a lower frame and a long side column are attached, and the short side column and the long side column are connected by a latch lock.

According to Patent Document 2, a transport container for storing an irregular shaped object such as a liquid, powder, or granule is disclosed, and a pallet, a corrugated rectangular cylinder, and a lower edge of the rectangular cylinder are provided. A square frame that is generated by internal pressure from the filling of the inner bag by connecting a lower frame that supports and fixes the rectangular cylinder on the pallet, an upper frame that is fitted to the upper edge of the rectangular cylinder, and an upper and lower frame. And a stay that supports the swelling of the body, and the stay is disposed across the height of the rectangular cylinder.

However, such conventional assembly-type containers have the following technical problems.
First, the number of parts is large, and it takes time to assemble the container, and if the number of parts is large, it is difficult to effectively prevent the cylinder of the container from being swollen.
More specifically, in both Patent Document 1 and Patent Document 2, in order to ensure the structural strength of the cylinder itself, the irregularly shaped filler fits into the inner surface of the cylinder and exerts a large pressure uniformly on the inner surface. In Patent Document 1, a side plate panel having an upper frame, an intermediate frame, and a lower frame attached to the outer surface is provided, and adjacent side plate panels are coupled to each other by a latch lock. In order to reinforce the cylindrical body, a vertical frame is provided on each of the upper and lower edges of the rectangular cylindrical body, and the stay is connected to the upper and lower frames to support the swelling of the rectangular cylindrical body caused by the internal pressure from the filling of the inner bag. Provided.

As described above, in any container, the material strength of the cylinder itself is reinforced by the structural material, and the structural strength including the compressive strength of the cylinder is ensured. In the case of a large number of solid materials, unlike an indefinite form of filling, pressure is not uniformly applied to the inner surface of the cylindrical body, but rather, a force acts to locally expand the cylindrical body.
In such a case, rather than allowing torsional deformation of the cylinder due to the storage of the filling to some extent, the force is utilized to prevent further torsion, while the number of parts is small. There is a need in the industry for an assembling container and an assembling method of the assembling container that can effectively prevent the swelling of the body and can be assembled efficiently.
