The present invention has been made based on the above-mentioned circumstances, and its purpose is to be able to accommodate items that require waterproofing, insect proofing, deodorizing, etc., and to be assembled into an oil-sized container that is easy to handle. The purpose is to provide a storage container.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned problems, a storage container according to the present invention includes a cardboard box and a synthetic resin sheet inserted inside the cardboard box. A part of the bag is attached to the inner wall of the cardboard box.

The position where the bag and the inner wall of the cardboard box are attached is preferably on the inside of a pair of opposing side wall surfaces (inner wall surfaces) of the cardboard box.

Furthermore, the present invention is characterized in that it includes a box-like body that is assembled and used, and a bag that is partially fixed to the box-like body.

(Function) The storage container configured as described above has a synthetic resin bag partially affixed to the inner wall of the cardboard box, so it can be folded like a normal cardboard box before being assembled. When the folded summit container according to the present invention is assembled in the same way as a normal cardboard box, since a part of the synthetic resin bag is attached to the inside of the cardboard box, this bag also unfolds at the same time.

In particular, it is preferable to provide the attachment positions on a pair of opposing surfaces of the cardboard box so that the bag will naturally spread when the cardboard container is assembled.

A storage container that includes a box-like body that is assembled and used and a bag that is partially fixed to the box-like body also exhibits the same effect as described above.
