PROBLEM TO BE SOLVED: To provide a delamination container capable of allowing an inner bag to quickly contract and an outer shell to be quickly restored to the original shape.SOLUTION: A delamination container comprises a container main body which has an outer shell and an inner bag, in which the inner bag is delaminated from the outer shell to contract as an amount of content reduces; and a valve member for adjusting air flow between an intermediate space between the outer shell and the inner bag, and an external space of the container body. The container body comprises: a storage part for storing the content; and a mouth part for discharging the content from the storage part. The outer shell comprises an ambient air introduction hole for communicating the intermediate space between the outer shell and the inner bag, and the external space, in the storage part. The valve member is fitted into the ambient air introduction hole. The storage part comprises: a cylindrical cylinder part; and a panel part depressedly formed from a part of the cylindrical part. The ambient air introduction hole is provided at a position adjacent to the panel part.SELECTED DRAWING: Figure 1 |
