Abstract

The invention comprises a method for packaging a dispensable substance, such as a food product, whipped cream, a hydrocarbon, or an air freshener, the method comprising the steps of: placing a first product component into a container, the container comprising a valve dispensing port; adding a second product component into the container, the second product component comprising at least one of: (1) a solid form of the second product component and (2) a liquid form of the second product component; sealing the container; and warming, after the step of sealing, the second product component in the container at least ten degrees Celsius, where the step of warming results in a phase change of all of the second product component into a gas phase, at least a portion of the gas phase of the second product component dissolving into the first product component to form the dispensable substance.

First claim

The invention claimed is:

1. A method for packaging a dispensable substance, comprising the steps of:
placing a first product component into a container, said container comprising a valve dispensing port;
adding a second product component into said container, said second product component comprising at least one of: (1) a solid form of said second product component and (2) a liquid form of said second product component;
sealing said container;
warming, after said step of sealing, said second product component in said container at least ten degrees Celsius, wherein said step of warming results in a phase change of all of said second product component into a gas phase, at least a portion of said gas phase of said second product component dissolving into the first product component to form the dispensable substance; and
propelling the dispensable substance from said container with the gas phase of said second product.

2. The method of claim 1 , further comprising the step of:
increasing pressure in said container, through the phase change of the second product, to a final pressure at least 0.26 atm greater than an initial pressure in the container of less than 1.31 atm.

3. The method of claim 2 , further comprising the step of:
propelling the first product from said container with the second product, wherein the first product comprises at least one of a hydrocarbon based solvent and an air freshener, wherein the second product comprises at least fifty percent carbon dioxide.

4. The method of claim 2 , further comprising the step of:
prior to said step of adding, pre-chilling said container to a temperature of less than five degrees Celsius.

5. The method of claim 4 , further comprising the steps of:
dispensing from container, at a pressure exceeding two hundred pounds per square inch, a mixture comprising:
greater than twenty percent by mass nitrous oxide; and
at least three percent by mass of at least one of molecular hydrogen, helium, molecular nitrogen, carbon dioxide, neon, argon, krypton, and xenon.

6. The method of claim 1 , further comprising the step of:
increasing pressure in said container, through a phase change of the second product, to a final pressure at least 0.25 atm greater than an initial pressure in the container of less than 1.3 atm.

7. The method of claim 6 , said step of adding the second product further comprising at least one of the steps of:
putting at least one gram of carbon dioxide into a beverage; and
putting at least one-fiftieth of a gram of nitrous oxide into the beverage.

8. The method of claim 1 , further comprising the step of:
prior to said step of adding, pre-chilling said container to a temperature of less than ten degrees Celsius.

9. The method of claim 1 , further comprising the steps of:
dispensing from said container, at a pressure exceeding two hundred pounds per square inch, a mixture comprising:
greater than thirty percent by mass nitrous oxide; and
at least three percent by mass of at least one of molecular hydrogen, helium, molecular nitrogen, carbon dioxide, neon, argon, krypton, and xenon.

10. The method of claim 9 , said step of dispensing further comprising the step of:
pressurizing a secondary container containing cream.

11. The method of claim 1 , further comprising the step of:
permeating the first product with the second product in said container, the first product comprising at least one of a cream, a fat, and a butterfat, wherein the second product comprises at least thirty percent nitrous oxide.

12. The method of claim 11 , further comprising the step of:
coating at least forty percent of a surface area of said second product in ice prior to said step of adding.

13. The method of claim 1 , further comprising the steps of:
forming a beverage with the first product and the second product; and
at least one of the steps of:
putting at least one of gram carbon dioxide into the beverage; and
putting at least one-tenth of a gram of nitrous oxide into the beverage.

14. The method of claim 1 , further comprising the step of:
coating at least fifty percent of a surface area of said second product in ice prior to said step of adding.

15. The method of claim 1 , said step of placing comprising the step of putting argon into said container.

16. The method of claim 1 , further comprising the step of:
forming a pressurized cartridge containing argon and nitrous oxide, said step of placing comprising the step of putting argon into said container.

17. The method of claim 16 , further comprising the step of:
pressurizing a profi container with said pressurized cartridge.
