<P>PROBLEM TO BE SOLVED: To provide an inner-fitting container which offers improved fitting performance without changing the height dimension of a fitted part of a container body, and a forming method for the container. <P>SOLUTION: The inner-fitting container is equipped with the container body 11 having an upward opening, and a lid 18 for closing the opening. The container body 11 is press-formed from a thermoplastic resin expanded sheet S, using a die 30 consisting of a male die 31 and a female die 38. The container body 11 is equipped with the vertically erected fitted part 15, and a flange 16 projecting outward from the upper end of the fitted part 15, the fitted part 15 and flange 16 being formed on the periphery of the opening. A fitting part 20 formed on the lid 18 is fitted into the fitted part 15 of the container body 11 inside the container body 11 to form the inner-fitting container 10. A cave-in groove 17, which is formed by press forming, is formed on a back surface corner C between the fitted part 15 and the flange 16 of the container body 11. <P>COPYRIGHT: (C)2007,JPO&INPIT |
