Abstract:
1. A spray can having a valve disk with a valve, which said valve disk is formed with a valve dome and a collar surrounding the dome at a radial intermediate distance and being fixed on a flanged rim of the can body by cramping, as well as having a rotatable spray head, which can be placed on a tappet extending upward out of the valve dome and which is axially movable for controlling the valve, and which together with the valve must be pushed downward against a spring force from a closed position into a spraying position, wherein a stop ring has been pushed and is seated by press fit, fixed against relative rotation, in the space between the valve dome and the collar, on the upward pointing side of which said stop ring a cam track, extending along the circumference, has been formed, over which, when the spray head is rotated into the closed position, one or several cams connected with said spray head can be moved at a slight distance or slidingly, while at least one stop connected with said spray head can be rotated back and forth between two stop faces extending transversely to the circumferential direction, and in one of the two end positions of the spray head determined by the stop faces the cam path is formed under the cam(s) with a recess which permits the spray head to be pushed down into the spraying position, characterized in that the circumferential surface of the stop ring providing the press fit has a plurality of radially elastically yielding lamellas, which, starting from origins thereof protrude obliquely at an acute angle to the radial direction and with end edges thereof rest against at least one of the collar or the valve dome.
