PROBLEM TO BE SOLVED: To always realize the use of the subject container in beautiful shape by providing an air chamber to be communicated with the outside by a valve structure part to suck air from the valve structure part to allow the shape to be returned to the original one by the restoring force of a container when a container is pressed and a hand is detached even if the container is dent. SOLUTION: The inside of a soft tube container is of a double structure which is divided into a content chamber 5 and an air chamber 6, the content chamber 5 and the air chamber 6 are communicated with the outside at a mouth part 3 of the container and at a valve structure part 4, respectively, and the valve structure part is of a structure in which no air in the air chamber 6 is leaked outside when the pressure is applied to the container. The content chamber 5 is separate from the air chamber 6, and the outer fitting of the container is split into two so that the content chamber is detached/attached to/from the container.
