A welding device (10a; 10b) for welding an outlet element (12a; 12b), in particular a valve, to a packaging material (14a; 14b), has at least one, in particular self-supporting, anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, and has at least one welding die (20a; 20b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one magnet unit (22a; 22b), which is configured to at least temporarily hold the anvil (16a; 16b) in a welding position, in which the welding die (20a; 20b) is configured for welding the outlet element (12a; 12b) to the packaging material (14a; 14b)

It is configured such that, for performing variable engravement for each formed object on a coil material to be fed to a press machine for molding a part of a can, a formed object with an engravement can be molded at a high productivity. A laser engraving device is a device for performing laser engraving on a coil material to be fed to a press machine for molding a part of a can, and includes a feeding mechanism for deeding a coil material at a predetermined speed, a laser head for irradiating the coil material fed at the predetermined speed with a laser beam, and performing engravement for each formed object, and a data communication unit for switching engraving data of the laser head. The data communication unit collectively switches a plurality of engraving data to be subjected to engravement on a plurality of formed objects, and the laser head continuously performs engravement of the plurality of engraving data on predetermined positions of the coil material.

By conducting a strict study on a plate thickness, a pressure resistance is improved while satisfying the demand for further reduction of the plate thickness.

A can lid has a center panel part, a panel wall part, a chuck wall radius part, a chuck wall part, and a curl part. t2>t1 holds, where t1 represents a plate thickness of the center panel part, and t2 represents a plate thickness of a bottom end of the panel wall part.

An upstream-side guidance part 400 is provided with plural upstream-side guidance members 410 guiding disc-shaped members 300. A downstream-side guidance part 500 is provided with plural downstream-side guidance members 510 guiding the disc-shaped members 300. The positions of the upstream-side guidance members 410 in the circumferential direction of the disc-shaped member 300 are different from the positions of the downstream-side guidance members 510 in the circumferential direction of the disc-shaped member 300, and at least one of the upstream-side guidance part 400 and the downstream-side guidance part 500 is able to move forward and backward with respect to the other.

A can lid comprises a metallic lid surface in which an opening is formed which is bounded by a closed margin of the lid surface and which is closed by a closure piece. The closure piece is separated from the surrounding lid surface by a microgap extending at least sectionally along the margin of the lid surface. A margin of the closure piece and the margin of the surrounding lid surface adjoin one another at the microgap. The closure piece can be moved out of the plane defined by the opening to release the opening. The can lid further comprises a layer composed of a plastic material applied to a flat side of the metallic lid surface in a manner covering the microgap. The margin of the closure piece and the margin of the surrounding lid surface are offset from one another transversely to the plane defined by the opening.

A container closure includes a generally planar body having a product side and a customer side. The container closure body defines a limited container opening and an actuation location. Further, the container body includes a force concentrating construction disposed adjacent the limited container opening.
