  • Publication number: 20220024679
    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.

  • Publication number: 20200037825
    Abstract: The invention comprises a method and apparatus for delivery of a product, such as whipped cream, from a pressurized container containing a deformable bladder, the deformable bladder separating a main compartment of the pressurized container into a pressure reserve zone and a pressurized delivery zone, where a membrane in the pressure reserve zone initially separates first chemical reagents from second chemical reagents. Upon a force creating an opening in the membrane, a reaction of the chemical reagents forms a gas, which alters a volume of the deformable bladder and the volume of the pressurized delivery zone with a corresponding increase in pressure of a deliverable gas in the pressure delivery zone. A resulting increased pressure of the deliverable gas, which permeates cream, maintains quality of delivered whipped cream from the pressurized container.
