Provided is a novel device for dispensing pastry dough, frosting or icing from a cartridge The device has a cartridge container and a hand-held gun. A hydraulic cylinder having a piston is coupled to the cartridge container. The piston acts on a plunger of the cartridge to apply pressure on the pastry dough, frosting or icing to permit the pastry dough, frosting or icing move to the gun to be dispensed. An alternative device utilizes a frosting cylinder in place of the cartridge.

[ What is claimed is:] [19.]19. A method of dispensing pastry dough, frosting or icing from a cartridge containing pastry dough, frosting or icing, the cartridge having a cartridge outlet and a plunger mounted for movement in a direction toward said cartridge outlet, the method including:inserting the cartridge into a cartridge container;coupling one end of a hose to a cartridge outlet, another end of said hose being connected with a hand-held gun having a gun valve, a finger trigger to actuate the gun valve, and a nozzle connected to the gun and having a shaped opening;coupling a hydraulic cylinder in a removable manner to an end of said cartridge container, said hydraulic cylinder comprising a walled cylinder having an inside surface, a piston in sealed slidable contact with said inside surface, a plunger shaft coupled to the piston on one end and an opposing end of said plunger shaft being constructed and arranged to apply pressure against said plunger of said cartridge, a guide at an end of said walled cylinder in sealed slidable contact with said plunger shaft, an internal volume being defined by said walled cylinder and said guide, said internal volume having an upper volume and a lower volume separated by said piston, respective liquid passages in said walled cylinder for allowing the passage of liquid to said upper volume and said lower volume, and a liquid supply line for supplying pressurized liquid to said liquid passages;connecting said liquid supply line to a source of pressurized liquid;allowing a pressurized liquid to flow into said upper volume to apply pressure against said piston and move the piston in a forward direction which moves the plunger shaft to engage the plunger thereby forcing the pastry dough, frosting or icing into the hose; andactuating said finger trigger to permit the pastry dough, frosting or icing to be dispensed from the nozzle.
