Pastry dough or cake decorating device

A device for dispensing frosting, icing or pastry dough from a cartridge containing pastry dough, frosting or icing comprising a plunger and a cartridge outlet, said device comprising:

• a walled cartridge container defining at least one internal chamber, each internal chamber being constructed and arranged to contain a cartridge and contain pressurized air, each internal chamber having an associated air inlet and an outlet;
• valve structure associated with each of said at least one air inlets for separately controlling air pressure applied to each of said at least one internal chambers whereby the air pressure can be varied in each individual internal chamber independent of one another;
• a hand-held gun having at least one gun valve for dispensing pastry dough, icing or frosting;
• an associated hose connecting each cartridge outlet to an associated gun valve in said hand-held gun;
• at least one nozzle comprising a head having a shaped opening, said at least one nozzle being connected to said gun;
• and
• a finger trigger on said hand-held gun connected to said at least one gun valve wherein when a cartridge containing pastry dough, frosting or icing is disposed in said cartridge container and said finger trigger is activated said at least one gun valve opens allowing air in said internal chamber to move the plunger and cause the flow of pastry, icing or frosting through said hand-held gun, said at least one nozzle and out of said shaped opening, wherein said walled cartridge further comprises associated water inlets for each internal chamber, each of said water inlets being provided with a back flow or shut of valve to prevent air pressure from exiting said internal chamber.

A method of applying pastry dough, icing or frosting from a cartridge comprising a plunger and a cartridge outlet, the method comprising:

• loading said cartridge containing pastry dough, icing or frosting into an inner chamber of a walled cartridge container defining at least one internal chamber constructed and arranged to contain said cartridge and contain pressurized air, each internal chamber having an associated air inlet and an outlet, a valve structure associated with each of said at least one air inlets for separately controlling air pressure applied to each of said at least one internal chambers, a hand-held gun for dispensing pastry dough, icing or frosting, an associated hose connecting each of the outlets to an associated gun valve in said hand-held gun, and a finger trigger on said hand-held gun connected to said gun valve whereby when said finger trigger is activated said gun valve opens allowing the flow of pastry, icing or frosting through said hand-held gun;
• adjusting the air pressure in said inner chamber containing said cartridge to a level sufficient to force said pastry dough, icing or frosting through an outlet in said cartridge, through said outlet in said inner chamber, though said hose and to said hand-held gun;
• and
• applying pressure to said finger trigger to cause flow of said pastry dough, icing or frosting through an outlet in said cartridge, through said outlet in said inner chamber, though said hose and through said hand-held gun.

A method of applying pastry dough, icing or frosting from a cartridge comprising a plunger and a cartridge outlet, the method comprising:

• loading a cartridge containing pastry dough, icing or frosting into an inner chamber of a walled cartridge container defining at least one internal chamber constructed and arranged to contain said cartridge and contain pressurized air, each internal chamber having an associated air inlet and an outlet, a valve structure associated with each of said at least one air inlets for separately controlling air pressure applied to each of said at least one internal chambers, a hand-held gun for dispensing pastry dough, icing or frosting, an associated hose connecting each of the outlets to an associated gun valve in said hand-held gun, and a finger trigger on said hand-held gun connected to said gun valve whereby when said finger trigger is activated said gun valve opens allowing the flow of pastry, icing or frosting through said hand-held gun;
• adjusting the air pressure in said inner chamber containing said cartridge to a level sufficient to force said pastry dough, icing or frosting through an outlet in said cartridge, through said outlet in said inner chamber, though said hose and to aid hand-held gun;
• applying pressure to said finger trigger to cause flow of said pastry dough, icing or frosting through an outlet in said cartridge, through said outlet in said inner chamber, though said hose and through said hand-held gun;
• loading a second cartridge containing pastry dough, icing or frosting into a second internal chamber, adjusting the air pressure in said second inner chamber containing said second cartridge to a level sufficient to force said pastry dough, icing or frosting through an outlet in said second cartridge, through said outlet in said inner chamber, though said hose and to said hand-held gun;
• and
• applying pressure to said finger trigger to cause flow of said pastry dough, icing or frosting through an outlet in said second cartridge, through said outlet in said second inner chamber, though said hose and to said hand-held gun.

A device for dispensing frosting, icing or pastry dough from a cartridge containing pastry dough, frosting or icing comprising a plunger and a cartridge outlet, said device comprising:

• a walled cartridge container defining a plurality of internal chambers, each internal chamber being constructed and arranged to contain a cartridge and contain pressurized air, each internal chamber having an associated air inlet and an outlet;
• valve structure associated with each of said at least one air inlets for separately controlling air pressure applied to each of said at least one internal chambers whereby the air pressure can be varied in each individual internal chamber independent of one another;
• a hand-held gun having at least one gun valve for dispensing pastry dough, icing or frosting;
• an associated hose connecting each cartridge outlet to an associated gun valve in said hand-held gun;
• at least one nozzle comprising a head having a shaped opening, said at least one nozzle being connected to said gun;
• and
• a finger trigger on said hand-held gun connected to said at least one gun valve wherein when a cartridge containing pastry dough, frosting or icing is disposed in said cartridge container and said finger trigger is activated said at least one gun valve opens allowing air in said internal chamber to move the plunger and cause the flow of pastry, icing or frosting through said hand-held gun, said at least one nozzle and out of said shaped opening.
