To solve the following problem: in a shape of a conventional plastic tube container, a function is not fully demonstrated even if a functional opening part such as a pump, a trigger and an airless pump, is attached to the container, and such a function is utilized in a mold container, however it is not adaptable to small-lot production of a wide variety of products and decoration, and moreover, when a contained amount is changed, an expensive new mold must be created.

The functional opening is attached to the plastic tube container, and in order to use the container while maintaining its function, a device is provided for mounting a pedestal to a container bottom part in a manufacturing process, and the pedestal is thermally welded to the container, Thereby, the container functions in a standing state. When the contained amount is changed, it can be changed by only changing cutting length of the tube, requiring no expensive mold. Moreover, just as the conventional tube container, the plastic tube container is adaptable to small-lot production of a wide variety of products and includes various decoration.
