Patent number: 11565534Abstract: A can body that has been subjected to outer surface painting (OV), inner surface painting (INS), and a neck process (SDN) but that has not been subjected to image formation is manufactured in a canning factory. The can body that has not been subjected to image formation is shipped to a beverage can manufacturing factory. At the beverage can manufacturing factory, an image formation process using a printer (PR) is performed. Specifically, ink is ejected from an inkjet head toward the can body, to thereby form an image on the outer circumferential surface of the can body. Thereafter, the can body is filled with beverage in a filler (FL), and then a can lid is attached to the can body in a seamer (SM).Type: GrantFiled: June 21, 2018Date of Patent: January 31, 2023Assignee: ALTEMIRA Co., Ltd.Inventors: Shinichi Ojima, Kazunori Ikeda, Asumi Suwa, Kazuhisa Masuda

Patent number: 10442564Abstract: The printing device, first, as shown in FIG. 2A, forms white layers (90) by a first white inkjet head on the surface of the can body (10). Next, as shown in FIG. 2B, irradiation of ultraviolet rays by a first irradiation lamp (261) is performed and the white layers (90) are cured. Then, the can body (10) is moved to a second white inkjet head and, as shown in FIG. 2C, more white ink is loaded on some of the white layers (90) formed by the first white inkjet head. As a result, the thickness of some of the white layers (90) is increased. Next, the can body (10) passes successively under multiple color inkjet heads. As a result, color ink layers (91) are formed on the surface of the can body (10) and the white layers (90), as shown in FIG. 2D.Type: GrantFiled: September 8, 2014Date of Patent: October 15, 2019Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Asumi Suwa, Kazunori Ikeda, Tetsuo Kashiwazaki

Patent number: 10414158Abstract: In ejecting ink from unused ink ejection ports or ink ejection ports not used frequently onto a can body to suppress ink clogging, the ink clogging is suppressed while degradation in the quality of an image to be formed on the can body is suppressed. On the surface of a can main body 110, a main image MG, which is a main image, and a strip-shaped image OG, which is a sub-image, are formed. The strip-shaped image OG is formed using ink ejection ports not used at forming the main image MG or low-frequency ink ejection ports not ejecting ink frequently. Thus, ink clogging hardly occurs in an ink jet head.Type: GrantFiled: March 18, 2016Date of Patent: September 17, 2019Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Tetsuo Kashiwazaki, Kazunori Ikeda, Asumi Suwa

Patent number: 10328721Abstract: A printing apparatus including a can body conveyance unit, an image forming unit, a light irradiation unit and one or more other can body stop locations. Light for curing an image on a can body is inhibited from reaching the image forming unit. An upstream side restricting wall (31) is positioned on the upstream side, namely, the side on which an ink jet head (240) is provided, of a can body (10) when the can body (10) is stopped at a mandrel stop location (811) or light irradiation stop location (811). The upstream side restricting wall (31) is thereby positioned between the can body (10) and the ink jet head (240), and ultraviolet light is restricted from heading toward the ink jet head (240).Type: GrantFiled: July 7, 2016Date of Patent: June 25, 2019Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Kazunori Ikeda, Tetsuo Kashiwazaki, Asumi Suwa

Patent number: 9850025Abstract: A first score line (430) is provided with a modified groove width portion (435) in which the groove width differs from the groove width of other portions. This modified groove width portion (435) is formed by imparting curvature to a point of a first side surface (430B) and this portion of a second side surface (430C) are respectively distended in an outward direction. To describe further, the modified groove width portion (435) is formed by forming respective recessed portions in the first side surface (430B) and the second side surface (430C). In so doing, rupture of a panel can take place in satisfactory fashion along a score line having a branched portion.Type: GrantFiled: April 9, 2014Date of Patent: December 26, 2017Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Kazunori Ikeda, Tetsuo Kashiwazaki, Asumi Suwa
