Patent number: 7036986Abstract: At least one branched chamber extends and diverges from a side wall of a pouch body. The branched chamber has an optional pouring spout at its distal end to permit the removal of the contents of the pouch. A readily unsealable seal member is optionally included to partition the branched chamber from the pouch body, thus providing a pouch wherein two or more different materials are mixed prior to removal from the pouch. A pouch having this structure provides excellent rupture protection of the readily unsealable seal member caused from, for example, handling, shipping, or dropping of the pouch.Type: GrantFiled: September 10, 2003Date of Patent: May 2, 2006Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Naoto Matsuda, Yasushi Hatano, Kikuo Matsuoka, Takashi Kuriki

Publication number: 20060072858Abstract: In the pouch of the present invention in which a pouring spout (3) is formed by means of a heat-sealed part (2) and a non-heat-sealed part (6) by heat sealing plastic films, the inside surfaces of the films that form the portion of the boundary area (Y) between the heat-sealed part (2) and non-heat-sealed part (6) of the pouring spout passage (4) on the side of the non-heat-sealed part (6) contact each other so that no gaps are left in a closed state. Accordingly, even if the pouch is suspended with the pouring spout (3) down following the opening of the pouring spout (3), the leakage of the contents such as a liquid or the like accommodated in the interior of the pouch from the pouring spout (3) a small amount at a time can be securely prevented. The gap-free contact of the inside surfaces of the films can be accomplished by uniformly pressing the films in the boundary area (Y).Type: ApplicationFiled: November 22, 2002Publication date: April 6, 2006Inventors: Kazuyuki Kurosawa, Naoto Matsuda, Ichiro Kunihiro
