ABSTRACT:
A spray head for an aerosol container, or the like, for producing a plurality of spray patterns: The spray head includes a central spool with an inlet on its bottom side in communication with the valve stem leading out of the aerosol spray container and with an outlet on the side of the spool. A shell or sleeve surrounds the spool and is longitudinally movable with respect to the spool. The sleeve has two longitudinally spaced apart outlets. Longitudinal shifting of the sleeve with respect to the spool aligns one or the other outlet from the sleeve with the spool outlet. A spring normally returns the sleeve so that a first outlet thereof is aligned with the spool outlet. The entire spray head sits on the valve stem. The valve stem with the associated valve element in the container is spring biased to normally close the valve. The spring force on the valve is less than the spring force in the spray head. Initial pressure applied to the spray head opens the valve, but does not shift the sleeve with respect to the spool. Further pressure on the spray head thereafter shifts the sleeve with respect to the spool. The different shifted positions of the sleeve with respect to the spool determine which outlet from the sleeve emits sprayed material. Each sleeve outlet has a nozzle for defining a respective spray pattern. Sealing elements on the spool assure exit flow only through the selected outlet from the sleeve and may also seal the other outlet.
