Abstract
A valve button of the type used primarily with an aerosol dispenser comprising a body having a valve stem recess for mounting on a substantially conventional valve stem associated with an aerosol dispenser valve assembly. The body has integrally formed therein an enlarged expansion chamber disposed in direct communicating relation with a terminal orifice passage which defines the exclusive path of travel of the product and expended propellant issued from the button. The terminal orifice passage has a predetermined shortened longitudinal dimension and a stepped configuration wherein the terminal orifice passage terminates in a recessed face portion formed in the outer wall portion of the button. The structural components comprising the button and the dimensions of the terminal orifice passage insure proper evaporation of the propellant as well as immediate dispensing thereafter to produce a desired spray pattern characteristics along with maintenance of a desirable surface temperature of the product being dispensed.
