Patent number: 9815300Abstract: A printing device (1) is provided with: a can body conveying mechanism (100) for sequentially conveying can bodies (10); and a can body moving mechanism (200) for moving the can body (10) while forming an image onto the outer circumferential surface of the can body (10) conveyed by the can body conveying mechanism (100). The can body moving mechanism (200) is provided with a rotating member (210) formed in a disc shape and rotating in a clockwise direction in the drawing. The can body moving mechanism (200) is also provided with plural image forming units (220) provided on the rotating member (210) and forming an image onto the outer circumferential surface of the can body (10) while moving the can body (10). The image forming units (220) are each provided with plural ink ejection devices for ejecting ink onto the outer circumferential surface of the can body (10). This provides an image forming device capable of increasing the number of can bodies on each of which an image can be formed per unit time.Type: GrantFiled: February 15, 2017Date of Patent: November 14, 2017Assignee: SHOW A ALUMINUM CAN CORPORATIONInventors: Yasushi Tashiro, Shinichi Ojima, Kazunori Ikeda, Kenyu Muraoka, Tetsuo Kashiwazaki, Asumi Suwa

Patent number: 9650172Abstract: In a panel (400), a protrusion (nipple) (420) is formed, which is flattened when a tab is secured to the panel (400) and functions as a rivet. The protrusion (420) is provided at a section of the panel (400) which is surrounded by a first score line (430) and which is located on a top part (433A) side relative to one end (431) or the other end (432) of the first score line (430). A second score line (450) connected to a curved part (433) of the first score line (430) is provided in the panel (400). Consequently, a decrease in the outflow performance of the drink is suppressed and a decrease in operability of the tab is suppressed, even if the tab or the opening is increased in size or the panel is reduced in size.Type: GrantFiled: April 25, 2012Date of Patent: May 16, 2017Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Kazunori Ikeda, Kenyu Muraoka, Tetsuo Kashiwazaki, Asumi Suwa

Patent number: 9239970Abstract: An image forming system (100) is provided with plural image forming apparatuses (200) that form images on can bodies (10), a can-body supply mechanism (300) that supplies can bodies (10) to the plural image forming apparatuses (200) successively, and a can-body discharge mechanism (400) that discharges the can bodies (10) on which images have been formed by the image forming apparatuses (200). Each of the image forming apparatuses (200) receives, at a can-body receiving position (1C), can bodies (10) supplied by the can-body supply mechanism (300). Each of the image forming apparatuses (200) also discharges, at a can-body discharging position (1D), can bodies (10) on which images have been formed. The can-body receiving positions (1C) and the can-body discharging positions (1D) are arranged more to the inner side than a circular virtual line (1B) that passes through the centers of the image forming apparatuses (200).Type: GrantFiled: December 21, 2012Date of Patent: January 19, 2016Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Kazunori Ikeda, Kenyu Muraoka, Tetsuo Kashiwazaki, Asumi Suwa
