It is about a box with a similar structure.

(Prior art) There have been many boxes that maintain a light-shielding state, but
Most of them had an inro-style structure, which made assembly complicated and difficult to mechanically assemble.

Furthermore, although it could be used for single-leaf products, it could not be used as a box from which the contents rolled into a roll could be sequentially taken out.

Examples of rolled contents include photographic materials, especially photographic paper for phototypesetting.
It is used by being wound into a roll and stored in a cassette. There are two types of cassettes: metal cassettes installed in phototypesetting machines, and disposable cassettes made of plastic, cardboard, cardboard, etc., and the present invention relates to a box that can be used as a disposable cassette.

Disposable boxes are destined to be low cost. Therefore, in order to lower costs, the base material is inexpensive, its manufacturing and assembly is simple, the roll of photographic paper can be easily stored in a dark place, and it has sufficient light-shielding properties even in a bright place.
A product that is highly compatible when loaded into a phototypesetting machine is required. As a structure for such a box, one in which many light-shielding materials were pasted on the inner surface of the box was developed, but boxes like this with many different materials on the inner surface are troublesome to put in and take out the contents. Moreover, there is a risk that the contents may get caught in the light-shielding material, making it even more difficult to store the contents in a dark place.No conventional product has been able to satisfy all of these requirements.
