た。Problems to be Solved by the Invention (1) The foldable container described in Japanese Utility Model Publication No. 50-8097 has one side plate a as shown in FIG. 13 as means for fixing the corners of the standing side plates. Ribs c having engaging grooves d are projected on the inner surfaces of both side edges of the side wall, and the other side plate b is shortened in lateral dimension by the protrusion amount t of the rib c and is bent inward at substantially right angles to both side edges thereof. A rib f that is engaged with the engaging groove d is provided on the outer surface of the rib e.
b is fixed to each other. For this reason, in each corner of the container, only two ribs c and e make a dead space, resulting in a dead space, which reduces the storage capacity of the container, or depending on the shape of the stored article, the protrusions of the ribs c and e are extremely large. There was a drawback that it became an obstacle.

らが解決すべき課題となっている。(2) In the folding container described in Japanese Utility Model Publication No. 63-3932, in order to enable stacking in a state where each side plate is folded, the upper end opening edge of the lateral side of the short side of the shallow container is long. It is configured to be one step higher than the upper end of the side surface portion in the direction. Therefore, in order to fold the side plates and enable stable stacking of shallow containers,
The height of the short side plate is limited to 1/2 or less of the inner dimension of the long side of the shallow container. Therefore, as long as the height of the upper opening edge of the container assembled by standing up each side plate is made uniform, the depth dimension of the container is limited by the height of the side plate on the short side, and the capacity of the container is limited. It is an obstacle to the production of large containers, and these are the issues to be solved.
