<p><P>PROBLEM TO BE SOLVED: To provide a container that is safely and properly compatible with decompression, by obtaining sufficiently enough and reliable decompression absorbing action using a decompression absorbing function unit arranged at the bottom of the container. <P>SOLUTION: The container includes: configuring a body portion of a container body 1 having a mouth cylinder part 3, a trunk 2, and a bottom 8; and arranging a soft bottom film 12 that is an in-mold material by closing an opening 11 formed in a bottom plate 10 of the bottom 8. Thereby, a large decompression absorption capacity is reliably ensured by a deflection deformation of the bottom film 12 the peripheral edge of which is closely connected to the bottom plate 10. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
