Abstract: A pressure regulating valve reduces the increased internal pressure in an aerosol spray can, filled with compressed gas, to a working pressure level for a spray valve (12). A regulating piston (52) is kept in equilibrium by a restoring force, and a sealing point (66, 68) is provided, which is closed at a pressure in the pressure regulation chamber (84) that is above the regulated pressure level. To prevent the precision of regulation from being adulterated by the decreasing internal pressure of the can as its contents are progressively withdrawn, a sealing means (86, 66; 67) is proposed, which seals off one free end of the piston (52, 74) from the internal pressure of the can and the regulated pressure. The variable internal pressure of the can is therefore no longer able to act on any axial face of the piston (52), and despite what may be a smaller piston face area, the precision of regulation is improved.

Abstract: A push-in-place aerosol dispenser valve configured to advantageously utilizes pressure exerted by pressurizing gas, within a pressurized aerosol container, as a force to sealingly secure the valve in place. The valve has a compliant molded plastic primary structure that integrally includes a nozzle that is resilingly responsive to operational manipulation. Defined within the nozzle is a discharge passageway that terminates at an outlet orifice. The passageway is normally blocked by an obstruent that is moveable by manipulation of the nozzle for unblocking the passageway. And, to accommodate push-in-place mounting the primary structure has an inwardly curved bottom, and a sloping annular retaining ledge that underlies the container opening curl. The bottom, ledge and uniformly distribute force exerted against the bottom, by pressurizing gas, form an equilibrium system that prevents the valve from being dislodged from the container.

Abstract: Disclosed is an aerosol actuator button for delivering a product such as an atomized air freshener liquid from a pressurized aerosol container wherein the spray pattern produced is tilted away from the central long axis of the actuator button and container. Tilting of the spray pattern is accomplished by placing the actuator button orifice at the bottom of an asymmetrical conical depression which is open to the surrounding atmosphere. More preferably, the orifice itself is asymmetrical with the shorter portion of the orifice being situated relative to the conical depression such that tilting of the spray is accentuated. This configuration causes the atomized spray to be tilted away from the central long axis in spite of the fact that the orifice is concentric with the central long axis of the actuator button. Also disclosed are dies for making such actuator buttons.
