Claims
- 1. A non-pressurized, non-compartmentalized dispenser of a deformable barrier material, the dispenser comprising a vessel formed with:
- 1) a deformable peripheral wall having an open neck;
- 2) a positive shut off valve member comprising a tubular valve stem having a central dispensation passage for dispensing a liquid; and
- 3) an actuating means which is biased towards the deformable barrier material of the dispenser;
- and wherein said dispenser contains a composition comprising a stable, aqueous, self-foaming, self-leveling liquid consisting essentially of a mixture of:
- (a) an effective amount of water to form a stable, aqueous, self-foaming, self-leveling liquid when mixed with components (b) and (c);
- (b) from about 0.1 to about 60 percent by weight of a surfactant wherein said surfactant is an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, or a mixture of at least two of anionic, nonionic, amphoteric, and cationic surfactants, said surfactant selected to form a stable, self-foaming, self-leveling liquid when mixed with components (a) and (c); and
- (c) from about 1 to about 20 percent by weight of of a dual purpose pressure agent selected to form an integral part of the composition and selected to volatilize upon spreading the composition with a single motion, wherein said dual purpose pressure agent is
- (A) neopentane,
- (B) a mixture of at least one gaseous hydrocarbon having 4 carbon atoms and a nonvolatile silicone oil, or
- (C) a mixture of at least one gaseous hydrocarbon having 4 carbon atoms and at least one liquid hydrocarbon selected from iso-pentane, pentane, 2,3-dimethylbutane, hexane, iso-hexane, and mineral oil, said dual purpose pressure agent selected to form a stable, self-foaming, self-leveling liquid when mixed with components capable of providing said liquid composition with
- (i) a self-foaming property upon dispensation as a liquid from said container, and
- (ii) a vapor pressure of from about 0.1 psig to about 17 psig above atmospheric pressure at a temperature of about 22.degree. C. in said container, said dual purpose pressure agent selected to form a stable, aqueous, self-foaming, self-leveling liquid when mixed with components (a) and (b);
- said resultant stable, aqueous, self-foaming, self-leveling liquid having a vapor pressure of from about 0.1 to about 17 psig in excess of atmospheric pressure at a temperature of 22.degree. C. in said container, said resultant stable, aqueous, self-foaming, self-leveling liquid adapted to be dispensed in the form of a liquid from said container, whereby the liquid foams instantaneously on spreading.
- 2. The package of claim 1, wherein the actuating means comprises a lever which is generally L-shaped having an upright arm and a horizontal arm, the horizontal arm adapted to engage with the valve, and actuate the valve.
- 3. The dispenser of claim 1, wherein the dispenser dispenses from about 4 to about 8 grams per second of the liquid composition.
- 4. A method of use of the combination of claim 1, comprising: inverting the dispenser, operating the valve to dispense a proportioned amount of the composition, spreading and rubbing the composition whereby the composition develops into a lather in less than about one minute.
