Abstract

The invention comprises an apparatus and/or a method of use thereof for dispensing whipped cream, comprising: a profi including a pressure containment housing, a first receiving port integrated into the pressure containment housing, a dispensing port integrated into the pressure containment housing, and at least a first pressure cartridge containing at least a liquid form of nitrous oxide, where the pressure cartridge includes a pressure gas delivery port and where a connection between the receiving port and the pressure gas delivery port form: (1) a section of a pressure containment unit encompassing contents of the pressure containment housing and the pressure cartridge and (2) an open path between the pressure containment housing and the pressure cartridge.

First claim

The invention claimed is:

1. A method for a user dispensing a whipped topping, comprising the steps of:
filling a refillable container with cream, said refillable container comprising: a pressure containment housing, a first receiving port integrated into said pressure containment housing, and a dispensing port integrated into said pressure containment housing, said step of filling further comprising a step of:
coupling, by the user, a pressure gas delivery port of a first pressure cartridge to said first receiving port of said refillable container, said first pressure cartridge containing at least nitrous oxide at a pressure exceeding two hundred fifty psi, wherein said step of coupling further comprises the step of:
forming a connection between said first receiving port and said pressure gas delivery port, said connection, at least temporarily, forming a pressure tight connection with an open path therethrough between said pressure containment housing and said pressure cartridge; and

pressurizing said refillable container with a first gas in said pressure cartridge comprising the nitrous oxide and a second gas in said pressure cartridge comprising at least two hundred fifty ppm of at least one of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, methane, xenon, and atmosphere.

2. The method of claim 1 , said step of pressurizing further comprising the step of:
passing said first gas and said second gas through a one-way valve.

3. The method of claim 1 , said step of pressurizing further comprising the step of:
passing said first gas and said second gas through a valve.

4. The method of claim 1 , further comprising the step of:
filling said pressure containment housing with at least the cream, said nitrous oxide, and at least one of nitrogen and argon, said nitrous oxide and at least one of said nitrogen and said argon passing from said pressure cartridge into said pressure containment housing.

5. The method of claim 1 , further comprising the step of:
dispensing from said pressure containment housing the cream, the nitrous oxide, the nitrogen, and the argon, said nitrogen and said argon present in a gas volume of said pressure containment housing at a concentration of at least 250 ppm.

6. The method of claim 1 , further comprising the step of:
pressurizing said pressure containment housing with a gas mixture from a headspace above a liquid in said pressure cartridge.

7. The method of claim 1 , further comprising the steps of:
initially pressurizing said pressure containment housing with at least one of a first set of gases, comprising nitrous oxide gas, argon gas, and nitrogen gas, contained in a first pressure cartridge; and
subsequently adding a second gas, of said first set of gases, to said pressure containment housing from a second pressure cartridge, said second gas comprising at least one gas not added to said pressure containment housing from said first pressure cartridge at a concentration greater than five percent.
