Description

527308 A7 B7 V. Description of the Invention (1) Field of the Invention The present invention generally relates to a collapsible container for liquid or powder contents. Specifically, the container includes a compartment defined by a flexible wall, and the compartment The volume of the chamber depends on the relative positions of the walls. The walls include two opposite side walls, the side walls have outer edge portions that are joined to each other, and the side walls are joined in a common connection portion along the outer edge portions. The invention also relates to a method for manufacturing the container. Background Art Containers of the type described in the citation are usually flat and sealed before filling. The side walls of the container are joined to each other in a planar manner so that the walls define a substantially zero compartment volume. A container is opened together with the filling and the liquid contents are supplied to the compartment. When the liquid content is supplied to the compartment, the side walls move apart, thereby increasing the volume of the compartment defined by the wall and adjusting the volume to the content. After filling is completed, the container is sealed again. The above types of containers are particularly advantageous in that they can be sterilized at the time of manufacture and can then be kept sterile and delivered to the user for aseptic filling of the liquid contents of the container. A container of this type is described, for example, in WO 9941 155, where a container is described which has a protruding conduit arrangement consisting of two interconnected protrusions on the side wall. The catheter device is sealed in the empty state of the container before filling, so the compartment defined by the container wall is completely sealed and sterilized by radiation, for example. During filling, remove an outer end of the catheter device in a sterilization chamber

Description of the invention (2) Open the container, and then insert a filling device into the catheter device under aseptic conditions to fill This container. The filling device usually has a push-out shape and ends at a point. The filling device is inserted into the catheter device, and this point faces the catheter device. When the filling device is inserted into the catheter device, the catheter device will become wider. Air must not penetrate the container during the filling procedure, so the filling device may be designed in such a way that the filling device is hermetically inserted into the catheter device. Therefore, the main purpose of the conduit device is to prevent air from penetrating into the compartment during the filling procedure. Any air penetration will actually cause a considerable amount of foam in the liquid content, which will prevent the container from filling satisfactorily. A container of the type described above has one disadvantage, even though it has several advantages. As mentioned above, the container must have a conduit arrangement that helps prevent air penetration during the filling procedure. However, this catheter device may cause a deteriorating environment when manufacturing a container, because the protrusions included in the catheter device will make it difficult to efficiently utilize the film material used to make the container. Specifically, these protrusions will cause a lot of waste, which obviously leads to bad extra costs. SUMMARY OF THE INVENTION After considering the above situation, one item of the present invention is to provide an improved container of the type described in the citation. Another project is to provide such a container, which can be manufactured with minimal waste, while the container can still be filled with liquid contents without creating any danger of air penetration.
