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.
