  • Whipped cream dispenser
    Patent number: 5553755
    Abstract: In a whipped cream dispenser incorporating a tilt-type aerosol valve the tubular actuator has at its base a downwardly facing annular shoulder. This shoulder, by butting against the metal of the valve pedestal, prevents further tilting and further stress on the tubular valve spout. Further, ribs on the stem and actuator keep the actuator in fully installed position on the valve stem.
