Patent number: 8789721Abstract: A square can capable of securing high sealing performance even if a curvature radius of a seamed portion at a seamed corner portion is reduced, enabling a reduction in a countersink depth, reduced in size, having excellent sealing ability and storage efficiency and a method and an apparatus for double seaming the square can. A second seaming roll (55) is guided by a model cam for second seaming having a model cam surface for second seaming formed in such a shape that it is swelled from a model cam surface for first seaming outwards at a corner seamed portion (5). Accordingly, the seaming shape of the corner seamed portion (5) is formed in such a shape that the seaming width thereof at the center of the corner seamed portion is larger than the seaming width of a linear sealed portion (4) and is swelled outwards to absorb an increase in sheet thickness at the corner seamed portion.Type: GrantFiled: May 16, 2006Date of Patent: July 29, 2014Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Kei Oohori, Kiyotaka Yoshida, Sunao Morishita, Kanji Kuroda, Norifumi Yasuda, Kazuo Ando, Hisashi Katoh

Patent number: 8505764Abstract: The structure of a clinch portion of a mounting cup is provided which can retain a gasket. The clinch portion includes a curl portion continuous with an upper end of an outer circumferential wall at an inner circumferential edge of the curl portion, and a curl skirt portion having an upper end continuous with an outer circumferential edge of the curl portion. The curl portion is made of a plurality of curved planes having different radii extending from the inner circumferential edge to outer circumferential edge. A space a portion of the gasket can enter is formed between a virtual curved plane with a radius constituting the inner plane of the curl portion and an inner curved plane or an outer curved plane, or between the virtual curved plane and both the inner and outer curved planes.Type: GrantFiled: April 17, 2009Date of Patent: August 13, 2013Assignees: Toyo Seikan Kaisha, Ltd., Toyo Aerosol Industry Co., Ltd.Inventors: Minoru Tasaki, Sunao Morishita, Kouji Kinoshita, Takaho Kumai

Patent number: 8360705Abstract: In seaming various shapes of cans, there is no need of replacement of a profiling cam or experience in techniques, thus enabling to reduce the number of components to be replaced and simplify a replacement work remarkably. Below a rotary driving ring (10), a holding ring (4) is mounted in such a manner that it can move horizontally and rotate integrally. Inside the holding ring (4), a curl roller (2) and a tightening roller (3) are mounted opposite to each other. The holding ring (4) is so mounted on a guide ring (6) as to be turned via a pressurization roller (5). The guide ring (6) is drive-controlled in the X-axis direction and Y-axis direction by an X-axis table (7) and a Y-axis table (8) driven by servo motors (14, 16) according to the shape of a can.Type: GrantFiled: June 28, 2007Date of Patent: January 29, 2013Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Kei Oohori, Sunao Morishita, Kazuhiro Tokunaga, Koichi Ishizaka, Yasuo Kumano

Patent number: 6338263Abstract: A method for manufacturing an embossed can body with a pattern printed on an outer surface of a cylindrical can barrel includes a plastic working step for forming a flange portion and a neck portion at an opening peripheral edge of the can barrel, and an embossing step for forming an embossed portion on at least a part of the pattern while aligning with the pattern. Thus, the pattern and the embossed portion can be aligned easily and accurately. Also, a stopping mark and a confirmation mark are formed on the can barrel, and a first sensor corresponding to the stopping mark and a second sensor corresponding to the confirmation mark are used. When the respective first and second sensors detect the stopping mark and the confirmation mark, it can be confirmed that the pattern on the can barrel is oriented in a predetermined direction.Type: GrantFiled: June 22, 2000Date of Patent: January 15, 2002Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Kazumoto Obata, Wataru Ookubo, Sunao Morishita

Patent number: 5829623Abstract: An easily openable can lid wherein buckling parts are provided nearby a peripheral groove formed on the can lid in a range of 25 to 65 degrees from the center of the top plate from a line between the tip end of the openable member and the center of the top plate in all sector segments formed when the can lid is divided into four sector segments by a line between an extreme end of the openable member and the center of the top plate and a line which passes through the center of the top plate and orthogonally intersects the above described line. A reinforcing part with a reinforcing effect smaller than a buckling effect is provided at a coupling part between the top plate and the peripheral groove or near said coupling part except for the buckling part at an opposite side of the openable member and its neighborhood to provide a difference of strength between the buckling part at the openable member side and the buckling part at an opposite side of the openable member.Type: GrantFiled: November 24, 1993Date of Patent: November 3, 1998Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Hideo Otsuka, Hiroyuki Terasawa, Shigeaki Yamanashi, Ichio Otsuka, Sunao Morishita
