PURPOSE: A multifunction double container is provided to prevent the contact of contents inside the container with air for delaying the decomposition of the contents. CONSTITUTION: A multifunction double container includes an air secluding check valve, a valve sheet, and a valve disk fixing groove. The air secluding check valve prevents the insertion of air into an inner container when contents in the inner container are discharged. The air secluding check valve is formed by inserting a fixing protrusion(1054) on a valve disk(1051) of the valve sheet(1052), to the valve disk fixing groove(1053). The valve sheet is formed by extending the inlet portion of the inner container. |
