摘要： To fix a valve piece encompassing a connecting shell and a valve to a can jacket, an embodiment of a method includes a welding step in which the connecting shell of the valve piece is fastened to the can jacket as a top closing element along with the valve by laser welding. According to an embodiment, a shoulder-shaped constricted cross section is embodied on the can jacket towards the top face thereof while the border area of the closing element which rests against the shoulder is tightly pressed theragainst and is sealingly joined to a laser seam, the top face of the can jacket lying inside the can. The method dispenses with the need to configure or fix a valve seat while eliminating the technically complex crimping step, thus also dispensing with the need for an installation used for crimping connecting shells in the filling station. The method makes it possible to produce also aerosol cans whose diameter is smaller than the diameter of a standard valve seat.
