<p><P>PROBLEM TO BE SOLVED: To provide a container, including a port which is little influenced by requirements for aligning a heat die with an attachment flange to facilitate fitting. <P>SOLUTION: This flexible container includes: flexible front sheet and flexible rear sheet fitted to each other along at least a part of a common outer periphery to define an inner cavity; and a container port with a nozzle, which is integrally molded on the flexible attachment flange disposed between the sheets. The flexible attachment flange includes a first layer flange having an inner surface and an outer surface, which is fitted to a second flange layer having an inner surface and an outer surface. When the flexible attachment flange is compressed between the flexible front sheet and the flexible rear sheet by a heat bar, the flexible attachment flange becomes flexible as at least a part of the inner surface of the second flange layer comes into contact with at least a part of the inner surface of the first flange layer. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
