Abstract: An aerosol valve construction comprising a tubular valve housing in which there is axially movable a valve stem cooperable with a seat in the housing. The valve stem is connected, in one embodiment of the invention, to an actuator button which is carried by an exterior resilient diaphragm having an outwardly crowned shape. Pressing the depress button flattens the diaphragm and depresses the valve stem, effecting an opening of the valve whereby product is discharged through an orifice in the button. The diaphragm tends to restore itself to the full crown shape due to its elasticity and also due to the pressure of product on its underside. When depressing force is removed from the button, the return of the diaphragm raises the valve stem and shuts off the valve. In other embodiments of the invention the resilient diaphragm which carries the depress button has a tubular portion acting as the valve housing and which is provided with a valve seat. The valve stem which extends into the valve housing and which is cooperable with the valve seat, is stationarily mounted. When the depress button is forced downward, flattening the diaphragm, it shifts downward the valve housing (portion of the diaphragm) while the valve stem remains stationary. This results in an opening of the valve. The valve closes when downward force is removed from the button, enabling the diaphragm to raise and restore itself to the original crowned shape or configuration. By use of the resilient crowned diaphragm to restore the valve to the closed position there is not needed the usual helical valve return spring which has been heretofore almost universally used.
