PROBLEM TO BE SOLVED: To ensure excellent quality by discharging a content surely with its residual quantity of at most 2% in the container in a manner having a flexible film constituting an inside container not to block the port during the period of suction discharge of a content even if a highly viscous content is contained. SOLUTION: This container is formed such that a rigid sliding rear wall plate 16 movable in parallel along the cylindrical inner peripheral surface of an outside container B is secured to the rear wall surface of an inside container A made of a pliable film (a), and the close contact interfaces of the inside container A and outside container B are bonded through an adhesive layer of adhesive force that becomes larger little by little toward the front wall surface side to the sliding rear plate side of the outside container B.
