Claims

[Claims for Utility Model Registration] (1) A push-out container for extruding fluid contents from an extrusion port, comprising: a flexible inner container filled with the contents and communicating with the extrusion port; and the inner container. an elastic outer container enclosing a container and having a through hole, and by closing the through hole of the outer container and applying pressure, the inner container is pressed through the air between the inner container and the outer container. The extrusion type double container is characterized in that the outer container returns to its original shape by pushing out the contents, opening the through hole, and sucking air through the through hole. (2) In a push-out container that extrudes fluid contents from an extrusion port, a flexible inner container filled with the content and communicated with the extrusion port, and an elastic container that encloses the inner container and has a through hole. an outer container; and a check valve provided in the through hole of the outer container to allow air to flow only from the outside of the outer container to the inside of the outer container and to block air flow in the opposite direction. By pressurizing the outer container, the check valve closes and presses the inner container through the air between the inner container and the outer container to push out the contents, and the outer container returns to its original state. 2. A push-out double container, characterized in that the check valve opens when the container returns to its shape, and air is taken in through the through hole.
