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.

A spray head for being mounted to the valve of an aerosol spray container, or the like container, said spray head comprising: a first portion of said spray head, including a spool comprised of a body having a passage therethrough; said body having a plurality of sides; said passage having an inlet communicating from one said side of said body; said body passage inlet being connectable with the valve of an aerosol spray container; said body passage having an outlet; a second portion of said spray head positioned next to said spool; said second portion being movable longitudinally of and with respect to said spool while remaining next to said spool; said second portion having a first and a second outlet conduit means therethrough, both extending from the side of said second portion next to said spool to the outside of said second portion; said first and second outlet conduit means being spaced apart longitudinally along said second portion such that with said second portion at a first longitudinal position with respect to said spool body, said first outlet conduit means is positioned in communication with said body passage outlet, and with said second portion at a second longitudinal position with respect to said body, said second outlet is positioned in communication with said body passage outlet; said first and second outlet conduit means and said body passage outlet being respectively so placed that, without prior operator selection of a position for said second portion with respect to said spool by motion of said second portion across the direction of longitudinal motion of said second portion, said second portion may be shifted longitudinally between said first and said second longitudinal positions.
