Patent number: 8829400Abstract: A packaging container which includes a synthetic resin container body having a flange part and the cover member heat-sealed to the flange part of the container body. The cover member includes (1) an upper member in which inner surfaces of resin films are positioned opposite to each other to form an abutted part, an unsealed part communicating with the inside of the container body is formed by heat-sealing a peripheral edge part of the abutted part excluding one side of the abutted part forming a base part, and the steam releasing seal part is formed at the abutted part and (2) a lower member which covers a lower surface of the upper member and in which a steam guide part communicating with the inside of the container body is formed at or near the base part of the abutted part.Type: GrantFiled: August 9, 2006Date of Patent: September 9, 2014Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Hisakazu Yasumuro, Keizou Kanzaki, Shie Nishimoto, Hiroshi Akitoshi, Kikuo Matsuoka

Patent number: 8343561Abstract: Provided is a package for cooking in a microwave oven, in which a synthetic resin container body having a flange part is filled with contents and a lid is heat-sealed to the flange part to seal the package hermetically. Independent concave parts sandwiching a heat-sealed part are provided in a part of the flange part on the inner and outer sides of the heat-sealed part to form, on the heat-sealed part, a projection part directed to the inner direction of the container and serving as a steam releasing part by automatically opening. The package is prevented from being broken or deformed by preventing the heat-sealed part from being peeled immediately after the contents are placed in the container body. When heating cooking is performed in a microwave oven, the package improves the taste of the contents by the steaming effect. The lid is sure to automatically open by the increase of the pressure in the container.Type: GrantFiled: April 17, 2007Date of Patent: January 1, 2013Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Hisakazu Yasumuro, Shinji Tanaka, Kikuo Matsuoka

Patent number: 7942996Abstract: An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.Type: GrantFiled: August 14, 2009Date of Patent: May 17, 2011Assignees: Toyo Seikan Kaisha, Ltd., Asano Laboratories Co., Ltd.Inventors: Kikuo Matsuoka, Shinji Tanaka, Yasuyo Sano, Toshihiro Takai, Kenichi Mizoguchi, Hideki Usami, Tomoaki Haruta
