Abstract
The invention comprises a method and apparatus for packaging a dispensable substance, including the steps of: placing a first product component into a container; adding a second product component into the container at an initial pressure of less than 1.31 atm, the container comprising a valve dispensing port; sealing the container; and increasing pressure in the container through a phase change of the second product component to a final pressure in the container, the final pressure at least 0.26 atm greater than the initial pressure. Optionally, the second product component warms in the container at least ten degrees Celsius and undergoes a phase change from a solid or liquid to a gas, which increases pressure in the container and functions as a propellant and/or as an expansion agent.
