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.
An actuator comprising an actuator skirt defining a recess sized to receive a portion of a pedestal of a mounting cap. The actuator having a passageway providing communicating between a valve stem and an insert received within an insert cavity of the actuator. The insert has a discharge orifice and a locking member while the insert cavity has a mating locking member. The mating locking members engage with one another to retain the insert within the insert cavity and allow adjustment of a spray discharge pattern of the insert. The insert cavity has a cavity hub which engages with a leading end of the insert, in an over lapped manner, to form a fluid tight seal therewith and minimize leakage therebetween. An angle rib is attached to a lower surface of the actuator body and abuts against the pedestal, prior to full depression of the actuator, to tilt the actuator slightly upward so that the discharge product does not impinge against the aerosol container.
An actuator orifice and an actuator for enhancing or creating a foam from a pressurized material dispenser. The actuator includes a skirt attached to the dispenser and a trigger movably mounted to the skirt. The trigger includes a flow conduit with a socket for receiving a valve stem. The socket exerts pressure on the stem to release contents of the dispenser. The trigger includes a hollow flow diverter located within the chamber. The flow diverter has a side wall and an end wall extending inwardly from the flow diverter side wall. The flow diverter side wall in turn has slots that provide fluid paths between the flow conduit and a surrounding chamber. The chamber side wall has recesses. Each slot laterally directs contents of the dispenser into at least one of the recesses in the chamber side wall when the valve is activated by the trigger.
