[Prior Art] Conventionally, in an assembled container made of synthetic resin, a meshing part 4 is formed at the side end of the side plate 3, as shown in Utility Model Application Publication No. 149435/1989 shown in FIGS. 9 and 10. A coupling hole 6 penetrating vertically is formed in the engaging part 4, a protrusion 2b is formed in the bottom plate 2a, and a recess 3a is formed in the side plate 3.
is formed, the protrusion 2b is fitted into the recess 3a, the engaging parts 4 of the side plates 3, 3 are engaged with each other, the connecting rod 10 is inserted and connected to the coupling hole 6 in the engaging part 4, and the bottom plate 2a is connected. The container is assembled by connecting the side plates 3 to the container.

[Problems to be solved by the invention] However, in a container with such a structure,
The bottom plate 2a does not have an insertion groove for inserting a fork of a forklift, and the container cannot be transported by a forklift.The assembled container of the conventional example shown in FIG. 9 is just an assembled container. 2a
Because the protrusion 2b is fitted into the recess 3a of the side plate 3, assembly becomes troublesome, and the bottom plate 2a, which is not as strong as a pallet, bends when storing heavy objects and transporting containers. There was a problem that there was a risk that the connection with the side plate 3 would come off. Therefore, it is conceivable to place a side plate 3 around the periphery of a pallet that can be transported by a forklift and connect the side plate 3 to the pallet, but such an assembled container does not yet exist, and in such an assembled container, the pallet and Not only the strength of the connection with the side plate 3 but also the strength of the connection between the side plates 3 and 3 at the upper end of the side plate 3 may be difficult to maintain, and the container may become insufficient. However, there are problems in that it requires a large number of parts and is difficult to assemble and disassemble.

The present invention was devised in view of these problems, and its purpose is to facilitate the assembly and disassembly of such containers while transporting them by forklift, and in particular to provide sufficient strength in the assembled state. Our goal is to provide an assembly container that can be used as a container.

Further, guide holes 24 are bored at both ends of the side plate 3 from the upper end to the lower end so as to face the coupling holes 6. A pair of fitting protrusions 22 are provided on the lower surface of the side plate 3 so as to protrude from the center portion of the side plate 3 in the length direction. Although these fitting recesses 21 and fitting protrusions 22 are formed into square shapes in plan view, they may have other shapes. The coupling fitting 7 is L-shaped in plan view, and has a hole 9 passed through it and a vertical piece 8 hanging from its outer edge.

[Effects of the invention] In summary, the present invention uses a pallet with an insertion groove into which a fork of a forklift is inserted as a bottom plate and assembles a side plate thereon, so that the assembled container can be transported and handled by a forklift. Although it contributes to circulation, a fitting recess is formed on the upper surface of each side of the pallet, and a fitting protrusion for standing installation is provided on the lower surface of the side plate, and the fitting protrusion fits into the fitting recess. Since the side plates are erected on the periphery of the pallet, it is easy to position the side plates during assembly, and after assembly, the side plates are prevented from escaping to the outside, and the contents stored therein are prevented from escaping. It is possible to prevent the side plates from swelling and coming off the pallet, increasing the assembly strength, and connecting holes are formed at the four corners of the pallet, and a substantially comb-like engaging part is formed at the side edges of the side plates. At the same time, a coupling hole is formed in the vertical direction, a coupling fitting is interposed, a connecting rod is inserted through the coupling hole in the meshing part and the connecting hole of the pallet, and a nut is screwed into the threaded part of the connecting rod, so that the pallet and the side plate can be connected. Connection and disassembly can be easily performed by screwing together the connecting rod and the nut while strongly preventing separation from the connecting rod.In particular, in this invention, the upper end surface of the engagement part of the side plate has an L-shaped shape in plan view. Since the coupling fitting is mounted and the vertical piece hanging down from the outer edge of the coupling fitting comes into contact with the upper outer surface of the engagement part of the side plate,
It is possible to prevent the side plate from falling outward at the vertical piece, improve the bonding strength at the upper part of the side plate, and facilitate assembly and disassembly while handling it with a forklift. There is an advantage that not only the bonding strength to the pallet at the top but also the bonding strength at the upper part of the side plates to each other can be made sufficient. A plurality of approximately comb-shaped engaging parts are spaced at predetermined intervals at the side edges of the side plates and are formed at different levels on both edges, so the side plates only need to have one type of shape, reducing the number of parts. It is possible. Moreover, since the coupling hole of the meshing part is approximately C-shaped and opens outward in the thickness direction of the side plate, even if the side plate is molded with resin, it can be easily cut out. The connecting hole is formed so that the side plates can be reliably connected by the connecting rod, and can be supported by the bottom of the container on the connecting rod, so there is no problem in terms of strength.
