Zusammenfassung:	Tin plate drink cans are made by deep-drawing and ironing a circular blank to form an open cylinder with a domed top, punching a hole in the dome, fitting a resealable closure with a screw cap in the hole and closing the open end with a flat round metal base by flanging and folding to form a double fold. A process for the production of drink cans from sheet metal, especially tinplate, comprises: (a) making a circular blank, forming this by deep drawing and ironing to a cylindrical body open at one end, with a cylindrical wall and an outward-curved dome-shaped end (top); (b) punching out a hole in the center of the top; (c) fitting a resealable closure system with a screw cap into the hole; and (d) closing the open end of the can with a separate, essentially flat, round metal base by flanging and folding to form a double fold.
