- the can lid 1 is configured such that the tab 14 is formed by pressing the laminated metal plate 50 instead of laminating the film layer on the formed tab.
- the film layer 61 is removed when the rivet hole 31a is formed, the film layer 61 does not exist on the inner peripheral surface of the rivet hole 31a. That is, by forming the tab 14 from the laminated metal plate 50, the film layer 61 does not hinder the assembling property when the tab 14 is assembled to the panel portion 11.
- the apparatus currently used conventionally can be used for the manufacturing apparatus of the tab 14, and the assembly apparatus of the can lid 1, installation cost is not increased.
- the laminated metal plate 50 has the printed layer 62, the decorativeness of the tab 14 can be improved.
- the print layer 62 is disposed between the substrate 51 and the film layer 61. For this reason, when the tab 14 is formed from the laminated metal plate 50, even if the laminated metal plate 50 is formed in a direction in which the surface of the substrate 51 provided with the film layer 61 extends, the printed layer 62 is It is protected by the film layer 61. As a result, the print layer 62 is not peeled off, and the print layer 62 can be prevented from being thinned as much as possible, so that the print layer 62 can maintain a preferable color. As a result, the decorativeness of the tab 14 does not deteriorate.
- the coating material constituting the printed layer 62 does not peel off and adhere to the surface of the tab 14 or adhere to the mold used for molding. Moreover, since it can prevent that the peeled coating material adheres to a metal mold
- the plurality of printing portions 62a of the printing layer 62 are randomly arranged in a plurality of colors on the film layer 61 by gravure printing, so that the colors of the formed tabs 14 are random.
- the color of the tab 14 of the produced can lid 1 becomes random.
- the color of the tab 14 of the produced several can containers can be made random.
- the can lid 1 is used for a can container, at the time of sale, a plurality of can containers having tabs 14 with random colors are arranged on a display shelf or the like of the store. It becomes possible to improve.
- the tab 14 is formed using the laminated metal plate 50, so that the tab 14 can be arranged in the circumferential direction with a simple configuration. Rotation can be prevented.
- the printing pattern of the printing unit 62a of the printing layer 62 is not limited to the above-described random arrangement.
- a plurality of tabs arranged in the horizontal direction can be printed as a single printing unit 62 a in a single color or a plurality of colors.
- the laminated metal plate 50 may have a configuration without the print layer 62. That is, if the laminated metal plate 50 has the film layer 61, the rotation of the tab 14 can be prevented.
- the gravure printing is preferable for the printing layer 62, it is not limited to gravure printing, and other printing methods may be used.
- the film layer 61 may be colored.
