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.

Claims

1. In a whipped cream dispenser comprising:

a. an aerosol container having at its upper end a tilt-type valve disposed in a metal valve pedestal having a side and a top and a central aperture receiving an upwardly directed tubular discharge stem, and the container enclosing a whipped-cream-producing product and propellant means,

b. a unitary tubular whipped-cream actuator molded of rigid plastic and defined by an outer tubular body including a base end with an outward skirt disposed over the valve pedestal and a discharge end having spaced fingers, a support partition in the body intermediate the ends of the body formed with a central passage having a downward tubular nipple surrounding and fitting snugly over the aerosol discharge stem, and an inverted U-shaped bridge having a bight and legs bestriding the passage and unitary with the partition, the bight of the inverted U-shaped bridge being spaced from the central passage and comprising deflector means confronting the passage,

the improvement wherein the skirt is defined by a short rigid radial outward flange having a downwardly facing shoulder and a generally downward annular wall following and surrounding the pedestal, the shoulder being adapted during dispensing to engage the top of the pedestal at a point of engagement when the actuator and valve stem are tipped, the point of engagement serving as a stop to limit further tilting of the actuator to avoid breaking of the stem.

2. A whipped cream dispenser as claimed in claim 1 including further retaining means to hold the acuator fully installed on the stem.

3. A whipped cream dispenser as claimed in claim 2 wherein the retaining means comprises an inward annular rib on the actuator and an outward peripheral rib on the stem proximate and above the rib on the actuator, the ribs together retaining the actuator fully installed on the stem.

4. A whipped cream dispenser as claimed in claim 2 wherein the actuator is tilted, the lower end of the skirt also engages the side of the pedestal to impede further tilting.
