ABSTRACT:
An aerosol sprayhead assembly which includes a restriction between a sprayhead inlet communicating with an aerosol container and a nozzle opening which produces a fan-shaped spray pattern. The restriction acts in cooperation with the nozzle opening to provide a more uniform spray than may be achieved using an otherwise identical sprayhead which does not include the restriction. In one embodiment of the invention, the restriction defines an orifice formed as part of the sprayhead. In another embodiment, the restriction defines a single orifice or a plurality of orifices located within an outlet tube terminating in the nozzle opening. In a further embodiment of the invention, the restriction defines an integral reduced cross-section portion of the outlet tube.
