International Classification:

A47J 31/44
B67D 1/12
C12C 13/00

Abstract:

The invention comprises an apparatus and method of manufacture thereof for forming a frothing agent, including the steps of: forming a frozen pellet by at least partially immersing a first material in a liquid, the first material including at least one of: (1) a solid particle comprising at least thirty percent nitrous oxide by mass and (2) a liquid drop comprising at least thirty percent nitrous oxide by mass; sealing the frozen pellet in a container comprising an initial pressure exceeding one hundred pounds per square inch; and heating contents of the container, the step of heating resultant in: (1) a phase change of the nitrous oxide; and (2) formation of the frothing agent.

Appl. No.:

16/601601

Inventors:

Christian T. Metcalfe - Mercer Island WA, US
W. Davis Lee - Rockport ME, US

International Classification:

A47J 43/12
B65D 83/30
B65D 85/72
A23L 2/54

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.

International Classification:

A23C 13/14
A23L 2/54
A23C 11/00

Abstract:

A container having pressurized gas, the container includes an outlet, a liquid substance, a first gas dissolved in the liquid substance; and a noble gas. The liquid substance and the first gas are dispensed from the outlet when the container is oriented in a first position, and between 10-90% of gas that is dispensed from the outlet when the container is oriented in a second position includes the noble gas and the pressurized gas within the container has a pressure that is between 100 to 300 psi, wherein the liquid substance comprises less than 20% by weight of fat prior to dissolution of the first gas therein.
