SOLUTION: An inner storage bag 2 formed of a flexible plastic film and inflatable in a balloon-like manner is fitted to an inner side of a vessel 1 with a cap 4 attachably/detachably fitted to a mouth part 3, and a nozzle 5 is fitted to an upper portion of the inner storage bag 2. The outside diameter of the nozzle 5 is smaller than the inside diameter of the mouth part of the vessel 1, and a ring-shaped locking part 6 of the diameter larger than the inside diameter of the mouth part of the vessel 1 is provided on the upper part. This nozzle 5 is inserted in the mouth part 3 of the vessel 1 to form an exhaust passage 8 therebetween, and an exhaust hole 7 communicated with the exhaust passage 8 is opened in a side surface of the ring-shaped locking part 6. After mayonnaise 10 is used, the inner storage bag 2 is drawn from the mouth part 3 integrally with the nozzle 5. COPYRIGHT: (C)2004,JPO
