A spray actuator which has an inlet which communicates with a discharge orifice outlet via a passageway and a discharge cavity. The discharge cavity accommodates a central post therein which supports a plurality of axial fins that may be each provided with stop shoulder. An insert member, carrying a discharge orifice, is received within the discharge cavity and engages with the support fins and the stop shoulders. The insert member is provided with an annular lip which has an interference fit with the inner side wall, defining the discharge cavity, to retain permanently the insert member within the discharge cavity. An end face of the side wall of the insert member abuts against the stop shoulders to prevent overinsertion of the insert member into the discharge cavity and thereby prevent inadvertent deformation or crushing of the mechanical break-up. An end face of the central post has a mechanical break-up molded therein which impart a tangential spin to pressurized product as the product flow therethrough.

[ Wherefore, I claim:] [1.] A spray actuator for dispensing a pressurized product, said spray actuator comprising:a housing having an inlet communicating with a discharge orifice via both a passageway and a discharge cavity;said discharge cavity being opened at one end and having a cylindrical post located therein, an outwardly facing surface of said cylindrical post supporting at least three spaced apart fins, and each of said at least three space apart fins extending radially and axially from said cylindrical post;an end face of said post supporting a mechanical break-up having a plurality of radially extending supply passages for imparting a tangential flow to product as the product passes therethrough during actuation of said spray actuator;an insert member having said discharge orifice formed therein, and said insert member being received within the opened end of said discharge cavity and having an interference fit with said discharge cavity to seal the opened end of said discharge cavity, and an inwardly facing bottom surface of said insert member abutting against said mechanical break-up to facilitate product flow through said mechanical break-up and out through said discharge orifice during actuation of said spray actuator; andat least one of said at least three fins having a radially extending stop shoulder located remote from said opened end, and an end face of said insert member abuts against said stop shoulder of said at least one fin of said at least three fins to prevent over-insertion of said insert member into said discharge cavity.
