Abstract
An aerosol foam dispenser for dispensing a foam antiperspirant or deodorant composition. The foam dispenser can have a pressurized container adapted for one or more propellants and a liquid deodorant or antiperspirant composition; a valve assembly, which can be a metered valve assembly, having a valve stem; an actuating mechanism in operative communication with the valve assembly, a dome with a skin contacting surface and one or more exit orifices in fluid communication with the valve stem; and a dip tube.
Claims18
An aerosol foam dispenser comprising:
- a. a pressurized container having side walls, a closed base at a first end, and an open neck at a second end and defining a volume therein;
- wherein the volume is adapted for one or more propellants and a liquid composition;
- b. a valve assembly for selectively dispensing product from said aerosol dispenser as a foam comprising:
- i. a valve stem having a hollow center with a radial axis;
- wherein the hollow center is disposed for flow of the composition during dispensing and;
- ii. a mounting cup joined to the neck;
- c. an actuating mechanism in operative communication with the valve assembly;
- d. a dome coupled to the valve stem;
- wherein the dome comprises an inner surface and a skin contacting surface having one or more exit orifices;
- wherein the one or more exit orifices and the radial axis of the valve stem are non-linear;
- e. a diptube comprising an end open to the liquid composition and an end coupled to the valve assembly.
