PURPOSE:To permit a container to spray its contents until it becomes completely empty without producing vacant spaces in an inner bag member for allowing the contents to stay therein due to the gatherings of the inner bag member free from elastic contraction by providing a frame member which changes its shape according to the expansion and contraction of an elastic outer bag member. CONSTITUTION:A bag member 7 for filling its contents therein has a frame member 8 interposed between the outer peripheral surface of an inner bag member 71 and the inner peripheral surface of an outer bag member 72. The contents are filled in the inner bag member 71 consisting of a non-elastic film material against the elastic force of the outer bag member 72 consisting of an elastic material such as rubber, while the contents are shot out to the outside through a spray nozzle from the inner bag member 71. The frame member 8, upon expansion of the inner bag member 71, is formed into a nearly cylindrical shape conforming to to the exterior contour of the inner bag member 71 and having a swelling part in its center and, when the bag member is not filled with its contents, frame pieces 8a adhere closely to one another leaving little vacant space therein and the inner bag member 71 is free from hollows due to the gatherings and permits the contents to be sprayed out until it is completely emptied of its contents with none of them remaining therein. |
