  • Patent number: 10442564
    Abstract: 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.

  • Patent number: 10414158
    Abstract: 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.

  • Patent number: 10328721
    Abstract: 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).

  • Patent number: 9850025
    Abstract: 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.

  • Patent number: 9650172
    Abstract: 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.
