    摘要: A container closure construction wherein a closure flange having an upstanding internally threaded cylindrical neck surrounded by a laterally extending polygonal base is mechanically inserted by means of a punch press operation within a container wall opening from the under surface thereof. A tag ring element is in the same operation secured about the exterior surface of an upwardly drawn neck surrounding the container wall opening. An outward curling of the uppermost end of the flange neck serves to tightly clamp the upwardly drawn container wall opening neck between the flange and the tag ring element.

    摘要: Closure forming apparatus for simultaneously securing a closure flange and a tag ring element to a container wall in a single punch press operation. A lower die assembly is designed to support an internally threaded closure flange and an upper die assembly releasably retains a tag ring element. Closing of the die upon a container wall section permanently secures both the closure flange and tag ring element about a container wall opening.

    摘要: A method of cold drawing, forming and otherwise cold working a sheet metal blank to form a can end member for seaming to one end of a can body in which the can end has a continuous score line along which the can end is severed for complete removal of an end panel, and in which a protective metal fold is formed in the can end with portions of the fold metal extending to a location circumferentially outward beneath and beyond the score line location to present a dull hazard-free edge on the end panel when torn from the can end member. The metal working procedure includes steps of blanking, drawing, panel forming, curling, redrawing, resizing, coining, scoring, out-folding and embossing, by cold working operations performed on a thin sheet metal blank to produce a can end, accompanied by forming an integral rivet to join a pull tab to the end panel portion of the can end. A can end with a continuous annular three layer fold having a continuous annular score line in the top layer. The two lower layers extend radially beneath and beyond the location of the score line. There is a 100* sector of the three layer fold part extending on either side of a center line of a pull tab connected to the can end used to sever the score line which is thicker than the remaining extent of the continuous fold; and the top layer in the sector has a clearance space above the two lower layers.
