Publication number: 20220002017Abstract: There is provided a filling packaging machine which does not cause poor sealing between a sealing tape and the inner surface of a tubular packaging material in a laterally sealed portion as formed by ultrasonic sealing. A filling packaging machine includes a tape attachment device, a vertical sealing device and a lateral sealing device. The tape attachment device attaches a predetermined-width portion of a sealing tape to one end of one surface of a web-like packaging material in such a manner that a first edge of both edges of the sealing tape, which is to be located on an overlapping portion side of a tubular packaging material when viewed from an inner step of an overlapping portion, will be disposed at a position displaced from an outer step of the overlapping portion when viewed in the thickness direction of the tubular packaging material.Type: ApplicationFiled: September 26, 2019Publication date: January 6, 2022Applicants: SHIKOKU KAKOKI CO., LTD., NIPPON PAPER INDUSTRIES CO., LTD.Inventors: Yasuhiro Morikawa, Seiji Sato, Hiroshi Sora, Kazuhiko Sase, Shigekazu Miyagawa

Patent number: 11072454Abstract: A liquid paper container capable of preventing leakage of a liquid and intrusion of, for example, air into the container through a gap between a part of a corresponding one of top-portion horizontal folding creases formed in a blank sheet and a top-portion horizontal folding crease formed in a side sealing panel, which overlap with each other, top panels (11, 12) and side panels (15, 16) are respectively contiguous with upper ends of body panels through top-portion horizontal folding creases (9, 10, 13, 14). Bottom panels (21, 22) and inner panels (25, 26) are respectively contiguous with lower ends of the body panels through bottom-portion horizontal folding creases (19, 20, 23, 24). A side sealing panel (30) is contiguous with a one-side open end edge of a blank sheet (1A). A top-portion horizontal folding crease (31) and a bottom-portion horizontal folding crease (32) are formed in the side sealing panel.Type: GrantFiled: September 19, 2018Date of Patent: July 27, 2021Assignee: NIPPON PAPER INDUSTRIES CO., LTD.Inventors: Tatsuo Wada, Kazuhiko Sase, Takashi Omori, Yukihiro Tanaka, Eiichi Asoi

Publication number: 20090205994Abstract: The present invention provides a multilayer polyolefin film having a specific layered configuration that does not change the flavor or taste of contents when used as a sealant layer for the innermost surfaces of a liquid-storing paper container, and also a liquid-storing paper container material and a liquid-storing paper container that use this film. The invention has the following characteristic configuration: A multilayer polyolefin film for a liquid-storing paper container composed at least of one surface layer (a layer), another surface layer (c layer), and a middle layer (b layer); a multilayer polyolefin film for a liquid-storing paper container wherein the a layer, the b layer, and the c layer have the characteristics described below; and a liquid-storing paper container material and liquid-storing paper container that use this film.Type: ApplicationFiled: February 15, 2006Publication date: August 20, 2009Applicants: NIPPON PAPER-PACK, CO., LTD., SUN TOX CO., LTD., TOKUYAMA CORPORATIONInventors: Kazuhiko Sase, Shigekazu Miyagawa, Eiichi Asoi, Toshiya Oodera, Naohiko Kuramoto, Hajime Ueki

Patent number: 7540405Abstract: A paper container for fluid including a spout plug, in which the spout plug is formed of a spout positioned on a spout hole part for cutting and opening and incorporates a rotary opening blade and a cap. The spout plug is fitted to a top panel, which includes the spout hole part for cutting and opening in which a spout hole is formed in a paper base material and is sealed by a sealing layer. The contained further including a cut and opened piece fall prevention mechanism produced when the sealing layer is cut and opened by the rotary opening blade of the spout plug and capable of preventing a part of the cut and opened piece of the sealing layer from being cut off and giving hinge function to the uncut part of the cut and opened piece in the spout hole part for cutting and opening.Type: GrantFiled: April 23, 2004Date of Patent: June 2, 2009Assignee: Nippon Paper-Pak Co., Ltd.Inventors: Kazuhiko Sase, Susumu Onodera, Kenji Tanaka, Shigekazu Miyagawa, Eiichi Asoi
