Patent number: 7510515Abstract: A packaging bag comprises a main bag body and a framework member. The main bag body is made of plastic film material through a main bag body formation process. The main bag body has an opening and a plurality of heat sealed portions. The framework member is disposed in the main bag body. The framework member is joined to the main bag body prior to completion of the main bag body formation process. The framework member is foldable/unfoldable together with the main bag body, to enable the framework member and the main bag body to be shifted between a generally flat collapsed state and an expanded state.Type: GrantFiled: February 3, 2006Date of Patent: March 31, 2009Assignee: Hosokawa Yoko Co., Ltd.Inventor: Tooru Ichikawa

Publication number: 20080044115Abstract: There is provided a packaging bag capable of easily taking out an inner content of a desired amount from a packaging bag. The packaging bag provided with a fastener forms a packaging bag 1 by connecting a bag body 2 to a spout unit 3 as an independent member. The spout unit 3 is composed of opposing wall surface portions 11 and a fastener provided on inner surfaces of these wall surface portions 11, which are integrally formed through an injection molding process. The spout unit 3 includes a connection opening 15 for connecting one side end to the bag body 2 with the fastener 13 being boundary thereof and a closed portion 16 forming the other side end as the end edge of the packaging bag. A seal-opening portion 20 to be torn so as to separate the spout unit is formed to a portion between the closed portion 16 and the fastener 13.Type: ApplicationFiled: May 31, 2005Publication date: February 21, 2008Applicant: HOSOKAWA YOKO CO., LTD.Inventors: Tooru Ichikawa, Kou Go, Kazuhiro Umenaka

Patent number: 7211035Abstract: A reclosable packaging bag comprises a main bag body having an opening portion and at least one heat-sealed portion; and a linear fastener provided on the opening portion of the main bag body. The linear fastener is provided along the opening portion of the main bag body by an insert injection molding so as not to extend to the heat-sealed portions. A method for manufacturing the bag comprises the three steps. First, the first and second linear fastening members are formed on a prescribed position of a sheet of film material by an insert injection molding so as to be spaced from each other. These fastening members are engageable with each other to form a linear fastener. Second, the sheet of film material is folded in two so that the fastening members can engage with each other. Third, each of opposite portions of the sheet of film material thus folded is heat-sealed to form side heat-sealed portions.Type: GrantFiled: April 13, 2005Date of Patent: May 1, 2007Assignees: Hosokawa Yoko Co., Ltd, Lipton, division of Conopco, Inc.Inventors: Tooru Ichikawa, Kazunori Fujino, Raizo Kuge, Masahiro Ito, Graham Houlder, Hirokazu Suzuki, John S.
