WIPO Patent Application WO/2016/080313
Kind Code:
A1
Abstract:
Provided is a lamination separation container that excels in productivity. According to the present invention, provided is a lamination separation container that includes the following: a container body which has an outer shell and an inner bag and in which the inner bag separates from the outer shell and contracts in conjunction with a reduction of contents; and a valve member that adjusts the ingress and egress of air between an intermediate space between the outer shell and the inner bag and an external space of the container body. The container body is provided with: an accommodation part that accommodates the contents; and a port that discharges the contents from the accommodation part. The outer shell is provided, in the accommodation part, with an external air introduction hole that enables communication between the intermediate space and the external space. The valve member is provided with: a cylindrical body which has a hollow part disposed so as to enable communication between the external space and the intermediate space; and a moveable body which is accommodated within the hollow part so as to be moveable. The cylindrical body is provided with: a shaft part which is disposed within the external air introduction hole; and a lock part which is disposed on the external space-side of the shaft part and which prevents the cylindrical body from entering the intermediate space. The shaft part has a shape that tapers towards the intermediate space-side. The outer circumferential surface of the shaft part comes into close contact with the edge of the external air introduction hole, and as a result thereof the cylindrical body is fit to the container body. The cylindrical body has, at a surface which surrounds the hollow part, a stopper part that locks the moveable body when the moveable body moves from the intermediate space-side towards the external space-side. The stopper part is configured so that when the moveable body abuts the stopper part, the flow of air through the hollow part is blocked.
