PURPOSE:To prevent content-collecting cavities from being produced in an inner bag member free from an elastic contraction and permit the contents to be sprayed out with none of them remaining in the inner bag member by a method wherein the frame members around which string member is wound are made extremely large in contracting force together with an outer bag member and the string member attempting to recover its contracting force. CONSTITUTION:A bag member 7 for filling contents therein has a frame member 8 and a string member 9 interposed between the outer peripheral surface of an inner bag member 71 and the inner peripheral surface of an outer bag member 72. The inner bag member 71 consists of a nonelastic film material, the outer bag member 72 consists of an elastic material such as rubber and the contents are sprayed out to the outside from the inner bag member 71 through a spray nozzle by filling the inner bag member 71 with the contents on the one hand and due to the recovering force of the outer bag member 72 on the other. The string members adapted to be wound around frame members 8 and 8' consist of an expansible and contractible material, capable of responding the expansion and contraction of the bag member 7 and the frame members 8 and 8' and of imparting a large contracting force, upon contraction, to the frame members 8 and 8' and the inner bag member 71, thereby spraying out contents with none of them remaining in the inner bag member. |
