专利汇可以提供Non-pressurized package containing self-heating products专利检索，专利查询，专利分析的服务。并且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.，下面是Non-pressurized package containing self-heating products专利的具体信息内容。

权利要求

1. 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.

2. 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.

3. The package of claim 2, in which the oxidant is hydrogen peroxide.

4. The package of claim 2, in which the reductant is sodium sulfite.

5. The package of claim 2, in which the oxidant is a 1 to 20 percent aqueous solution of hydrogen peroxide, and in which the reductant is sodium sulfite.

6. The package of claim 2, in which the cosmetic is a shave cream.

7. The package of claim 6, in which the reductant-containing composition includes stearic acid, coconut oil fatty acids, diethanolamine, a water-soluble alkylene glycol, cetyl alcohol, and a polyethylene glycol monostearate.

8. The package of claim 3, in which the vapor pressure of the reductant-containing composition is in the range of from 0 to 10 psig at 25*C. and not greater than about 15 psig at 50*C.

9. The package of claim 8, in which the compressible gas is at least one member selected from the group consisting of C3 to C6 aliphatic hydrocarbons and halogenated C1 to C2 aliphatic hydrocarbons.

10. The package of claim 9, in which the compressible gas is a chlorofluoro C1 to C2 saturated aliphaTic hydrocarbon.

11. The package of claim 10, in which the organic solvent in said reductant-containing composition comprises a water-soluble alkylene glycol.

12. The package of claim 6, in which the compressible gas constitutes from about 1 to about 20 percent, by weight, of the solution thereof in said organic solvent.
