<P>PROBLEM TO BE SOLVED: To provide a container with a folded-back bottom wall, which is very stable when a plurality of such containers are stacked, has a strong bottom wall, and makes it possible to minimize the amount of remaining product. <P>SOLUTION: The container with a folded-back bottom wall has a first form A in which a bottom wall 4 is molded to project downwards from the lower surface of a body part 2, and then a second form B is formed by folding back the bottom wall 4 inside the body part 2. The boundary part between the bottom wall 4 and the body part 2 is folded, so that an outwardly-protruding folding groove 15 is formed around the periphery, and when the bottom wall 4 is folded back inside the body part 2 a folding line is formed at an upper opening edge 16 of the folding groove 15. <P>COPYRIGHT: (C)2011,JPO&INPIT |
