【effect】

 In the case according to the present invention, when both bottom plates are climbed up and pushed into the rectangular cylinder, they are pushed in by the contact between the tip edge of the bottom plate and the lower side surface of the projecting piece, and the edge of the through window and the inserting piece. The pushed state of both bottom plates can be maintained.

For this reason, no adhesive, staples, or adhesive tape is required to keep the lower surface of the rectangular tube closed, and it is extremely easy to assemble at the time of use, and it can be folded flat and stored in a low volume before assembly. it can.

Further, since the load of the inserted product is supported by the strut pieces, the force of directly pushing back the bottom wall does not act, and a stable closed state can be maintained.

Further, since both bottom plates pushed in are directed obliquely upward in the rectangular cylinder, they serve as a raised bottom. For example, even if a product having the same length (same height) as the rectangular cylinder is inserted, the upper edge of the product is a corner. It projects from the upper edge of the cylinder.

Therefore, it is easy to pull out upward.
