<P>PROBLEM TO BE SOLVED: To provide a storage bag which is kept superposed and does not become bulky. <P>SOLUTION: The storage bag 1 includes a storage body 10 having a storage part 12 and a cover 13 folded when used and superposed on the storage part 12, and a pair of freely bendable bone bodies 50a and 50b which are provided at folding parts of the storage part 12 and the cover 13 and have plasticity. The cover 13 is formed of first sheet bodies 21a and 21b, and the storage part 12 is formed of a second sheet body 22, one first sheet body 21a is set thinner than the other first sheet body 21b and the second sheet body 22. Filaments 40a-40e thinner than other parts are formed at a folding position part. When folding the storage bag, folding resistance is reduced by each of the filaments 40a-40e, and the thickness of the superposed cover 13 is suppressed and the folded state is stabilized by the bone bodies 50a and 50b, and as a result, the folded state does not become bulky. <P>COPYRIGHT: (C)2013,JPO&INPIT |
