Abstract
Abstract A non-pressurized package containing a product, especially a cosmetic product selected from the class consisting of those to be applied to skin and hair, said product comprising two separate compositions which are adapted to be mixed together to form a final heated composition which is dispensed from said package, said package having two separate compartments for separate storage of said two compositions, one of said compartments containing a composition comprising an oxidant in an aqueous medium, and the other of said compartments containing a substantially anhydrous composition which includes a reductant, a water-soluble organic solvent, a compressible gas which is substantially water-insoluble but which is soluble in said organic solvent, said compressible gas existing as a gas at a temperature in the range of ambient temperature to about 70*C. and existing as a liquid at said temperature under superatmospheric pressure, the aforesaid two separate compositions, when admixed, resulting in the release of said compressible gas by reason of the insolubility of said gas in the solution of said organic solvent and said water.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
151 words
A NON-PRESSURIZED PACKAGED PRODUCT COMPRISING TWO SEPARATE COMPOSITIONS WHICH ARE ADAPTED TO BE MIXED TOGETHER TO FORM A FINAL HEATED COMPOSITION WHICH IS DISPENSED FROM SAID PACKAGE, SAID PACKAGE HAVING TWO SEPARATE COMPARTMENTS FOR SEPARATE STORAGE OF SAID TWO COMPOSITIONS, ONE OF SAID COMPARTMENTS CONTAINING A COMPOSITION COMPRISING AN OXIDANT IN AN AQUEOUS MEDIUM, AND THE OTHER OF SAID COMPARTMENTS CONTAINING A SUBSTNATIALLY ANHYDROUS COMPOSITION WHICH INCLUDES A REDUCTANT, A WATER-SOLUBLE ORGANIC SOLVENT, A COMPRESSIBLE GAS WHICH IS SUBSTNATIALLY WATER-INSOLUBLE BUT WHICH IS SOLUBLE IN SAID ORGANIC SOLVENT, SAID COMPRESSIBLE GAS EXISTING AS A GAS AT A TEMPERATURE IN THE RANGE OF AMBIENT TEMPERATURE TO ABOUT 70*C. AND EXISTING AS A LIQUID AT SAID TEMPERATURE UNDER SUPERATMOSPHERIC PRESSURE, THE AFORESAID TWO SEPARATE COMPOSITIONS, WHEN ADMIXED, RESULTING IN THE RELEASE OF SAID COMPRESSIBLE GAS BY REASON OF THE INSOLUBILITY OF SAID GAS IN THE SOLUTION OF SAID ORGANIC SOLVENT AND SAID WATER.

Claim 3
Dependent Claim
183 words
A non-pressurized package containing a cosmetic product selected from the class consisting of those to be applied to skin and hair, said cosmetic product comprising two separate compositions which are adapted to be mixed together to form a final heated composition which is dispensed from said package, said package having two separate compartments for separate storage of said two compositions, one of said compartments containing a composition comprising a peroxide oxidant in an aqueous medium, and the other of said compartments containing a substantially anhydrous composition which includes a sodium or potassium salt of sulfurous or thiosulfuric acid as a reductant, a water-soluble organic solvent, a compressible gas which is substantially water-insoluble but which is soluble in said organic solvent, said compressible gas existing as a gas at a temperature in the range of ambient temperature to about 70*C. and existing as a liquid at said temperature under superatmospheric pressure, the aforesaid two separate compositions, when admixed, resulting in the release of said compressible gas by reason of the insolubility of said gas in the solution of said organic solvent and said water.
Claim 4
Dependent Claim
183 words
A non-pressurized package containing a cosmetic product selected from the class consisting of those to be applied to skin and hair, said cosmetic product comprising two separate compositions which are adapted to be mixed together to form a final heated composition which is dispensed from said package, said package having two separate compartments for separate storage of said two compositions, one of said compartments containing a composition comprising a peroxide oxidant in an aqueous medium, and the other of said compartments containing a substantially anhydrous composition which includes a sodium or potassium salt of sulfurous or thiosulfuric acid as a reductant, a water-soluble organic solvent, a compressible gas which is substantially water-insoluble but which is soluble in said organic solvent, said compressible gas existing as a gas at a temperature in the range of ambient temperature to about 70*C. and existing as a liquid at said temperature under superatmospheric pressure, the aforesaid two separate compositions, when admixed, resulting in the release of said compressible gas by reason of the insolubility of said gas in the solution of said organic solvent and said water.
