A pair of opposing end walls are formed in a single layer, and a cross plate is formed on one side of the side ends, corner plates are provided at both ends of the end walls, and respective cross plates are formed on the top wall of the side wall from both ends of the side wall. A long hole is provided in the width range of , tapered locking pieces with engaging protrusions are provided at both ends of the cross plate, and the locking pieces are inserted into the long hole to engage the engaging protrusion and the long hole. Corrugated paper boxes that are assembled together are generally known.

Because it is assembled into a box shape by engaging the two, the side walls have a double structure, whereas the end walls have a single structure, resulting in weak assembly strength. As a result, when a large number of heavy storage boxes filled with products are stacked in multiple stages, the storage boxes tend to collapse. In addition, since the crosspiece is located on the upper surface of the top wall end of the side wall,
When a product is stored in or taken out from the box, the product gets caught on the crosspiece and the elongated hole and the locking protrusion tend to disengage. For this reason, it was not possible to securely hold the box shape and safely accommodate the product.

保持される。 Each first top plate 9 is formed into a box shape as described above.
A tray 41 having a recess 41 a with a depth corresponding to the height of the storage box 1 is attached to the upper surface of the second top plate 21 . This tray 41 is made of a synthetic resin sheet that is blow-molded into a shape that corresponds to the inside of the storage box 1, and the outer long side plate 5 is attached to the upper outer periphery of the tray 41.
A flange portion 41b that engages with the upper outer surface of the outer short side plate 17 is integrally molded. The box shape of the storage box 1 is maintained by the engagement of the flange portions 41b with the upper outer surfaces of the longer outer side plates 5 and the shorter outer side plates 17.

度を維持することが可能である。 In this way, in this embodiment, each side plate can have a double structure, and a large number of storage boxes 1 containing products can be used.
It is possible to significantly increase the strength of each side plate against the load in the compressive direction that is applied when 1 is stacked in multiple stages. In addition, since the storage box 1 is assembled into a box shape without providing engagement holes in the long outer side plate 5 and short outer side plate 17 located on the outer surface of the storage box 1, engagement holes are provided in the long outer side plate 5 and the short outer side plate 17. At the same time, it is possible to effectively prevent a decrease in the strength of the corrugated paperboard due to moisture entering through the engagement hole. Furthermore, the assembled storage box 1
When the tray 41 is installed inside the tray 4
1, the first engagement holes 11 formed in each of the first top plates 9 are blocked, making it possible to avoid moisture from entering through the first engagement holes 11, thereby reducing the strength of the corrugated paperboard. storage box 1.
By locking the flange portion 41b to the upper outer surface of the storage box 1, it is possible to effectively maintain the box shape of the storage box 1 and maintain high assembly strength.
