## 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.

## Claims

### Claim 1

An apparatus for dispensing a whipped topping, comprising:
a 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; and
a first pressure cartridge comprising:
an internal chamber pressurized in excess of two hundred fifty psi;
a pressure gas delivery port; and
an initial pressure, at time of manufacturing, maintaining at least a portion of an internally contained nitrous oxide in a liquid state,
wherein a connection between said first receiving port and said pressure gas delivery port, at least temporarily, forms a pressure tight connection with an open path therethrough between said pressure containment housing and said first pressure cartridge,
wherein said first pressure cartridge contains a mixture of nitrous oxide and at least one of nitrogen and a noble gas at a pressure between three hundred and three thousand psi.

### Claim 2 (depends on 1)

The apparatus of claim 1, said pressure containment housing further comprising:
a second receiving port configured to couple to a second pressure cartridge containing at least one of argon and nitrogen.

### Claim 3 (depends on 1)

The apparatus of claim 1, said first receiving port further comprising:
a one-way valve preventing contents of said containment housing from flowing into said first pressure cartridge.

### Claim 4 (depends on 1)

The apparatus of claim 1, said first receiving port further comprising:
a pneumatic valve.

### Claim 5

An apparatus for dispensing a whipped topping, comprising:
a 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; and
a pressure cartridge comprising:
an internal chamber pressurized in excess of seven hundred forty psi,
a pressure gas delivery port;
at least five percent by mass of each of the nitrous oxide, nitrogen gas, and argon gas; and
at least one of neon, helium, krypton, hydrogen, and xenon at a concentration greater than 250 ppm,
wherein a connection between said first receiving port and said pressure gas delivery port, at least temporarily, forms a pressure tight connection with an open path therethrough between said pressure containment housing and said pressure cartridge,
wherein said pressure cartridge contains a mixture of nitrous oxide and at least one of nitrogen and a noble gas at a pressure between three hundred and three thousand psi.

### Claim 6

An apparatus for dispensing a whipped topping, comprising:
a 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; and
a pressure cartridge comprising:
an internal chamber pressurized in excess of two hundred fifty psi;
a pressure gas delivery port; and
both nitrogen and argon in a gas form at a concentration greater than 250 ppm and said nitrous oxide in a liquid form,
wherein a connection between said first receiving port and said pressure gas delivery port, at least temporarily, forms a pressure tight connection with an open path therethrough between said pressure containment housing and said pressure cartridge,
wherein said pressure cartridge contains a mixture of nitrous oxide and at least one of nitrogen and a noble gas at a pressure between three hundred and three thousand psi.

### Claim 7

An apparatus for dispensing a whipped topping, comprising:
a 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; and
a pressure cartridge comprising:
an internal chamber pressurized in excess of two hundred fifty psi;
a pressure gas delivery port; and
the nitrous oxide in a liquid phase and at least one of said nitrogen and said noble gas in a gas phase at a concentration of greater than 250 ppm,
wherein a connection between said first receiving port and said pressure gas delivery port, at least temporarily, forms a pressure tight connection with an open path therethrough between said pressure containment housing and said pressure cartridge,
wherein said pressure cartridge contains a mixture of nitrous oxide and at least one of nitrogen and a noble gas at a pressure between three hundred and three thousand psi.
