Abstract
A valve cup (60) for an aerosol dispensing can has a side wall (68) of lesser girth at the bottom than in an upper zone of which a portion is adapted to intensify the seal in the swaged seam between the cup curl (70') and the body curl (22). The side wall has for example a step (88) which acts as a fulcrum. In the swaged seam the seal is intensified in the area adjacent the step and down to a second point of contact where the side wall is deformed by the swaging tool (38) into contact with the body wall (1).
