【課題】 簡単な構成で容易に畳んだり、潰したり出来 る写真感光材料用熱可塑性樹脂成形品を提供する。
【解決手段】 枠体６の屈曲部６ａ〜６ｄに肉薄部１７ を設けることにより、枠体６を軽い力で容易に平たく畳 むことができ、嵩張らずに薄い形状で廃棄できる。これ により、廃棄物の減量化に大きく寄与でき、効率的な廃 棄物の保管、回収が可能になる。
PROBLEM TO BE SOLVED: To obtain a thermoplastic resin molding easily folded and crushed with simple constitution by constituting it foldable by forming a linear thin part along an optional side or on an optional plane and folding the plane along the thin part.
SOLUTION: An instant film pack incorporated in an instant camera is constituted of a pack case consisting of a back plate, a frame body 6, an upper plate and an engaging member engaged with them from all sides and integrally holding them, and plural instant films incorporated in the pack case. In this pack case, the upper plate and the bottom plate are easily detached from the frame body 6 by removing the engaging members at four corners of the pack case after all the instant films are exposed. Then, the thin parts 17 are formed at the bent parts 6a to 6d of the frame body 6. Thus, the frame body 6 from which the upper plate and the bottom plate are detached is easily folded to be flat by slight force and discarded in a thin state where it is not bulky.
