ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a water powered hand-held device for applying pastry dough, frosting or icing. The invention also relates to a method for applying pastry dough, frosting or icing.
BACKGROUND OF THE INVENTION
Decoration of cakes, pastries or the like foodstuffs with an attractive and tasty frosting or icing is a necessary and time consuming task. The preparation thereof frequently results in a significant mess, with spillage and clutter as a consequence of the required mixing containers, food coloring and flavoring bottles. This is especially true on a commercial level when it is desired to prepare frostings of varying colors for differing festive occasions as well as to provide frostings or trim icings of various flavors to complement the cake or pastry.
Frostings and icings having a high viscosity are usually applied using a baker's pastry bag, such as the ones disclosed in U.S. Pat. Nos. 4,961,517, 4,844,917, and Des. 310,317, or with a pastry gun as shown in U.S. Pat. No. Des. 335,069. The pastry bag and the pastry gun require significant force to squeeze the bag or trigger to force high viscosity frosting or icing through shaped nozzles and onto a cake or pastry. When used on a commercial level where numerous cakes and pastries must be coated with frosting and icing, the user's hands may become fatigues thus requiring the user to take rest breaks. Resting due to fatigue can undesirably raise the cost of preparing the cakes and pastries. Furthermore, fatigue can result in unwanted miss-application of the frosting or icing. Thus, there is a need for a device which applies high viscosity frostings and icings that does not require significant human force during application in order to avoid undesirable fatigue.
Forming pastry dough into shapes is similar to forming icing or frosting. Pastry bags have been used to form pastry dough into desired shapes. However, as with icing and frosting, when used on a commercial level where numerous pastries must be formed, fatigue can occur which requires significant amounts of resting. Resting due to fatigue can undesirably raise the cost of preparing the pastries. Therefore, a device which is capable of forming pastries without significant human force is desired.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide a device for applying high viscosity frosting or icing to a pastry dough or cake which does not require significant human force.
Another objective of the present invention is to provide a device for applying high viscosity pastry dough which does not require significant human force.
The above objective and other objectives can be obtained by a device for 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 within the cartridge in a direction toward the cartridge outlet, the device comprising:
a cartridge container defining an internal chamber constructed and arranged to contain a cartridge therein;
a hand-held gun having a gun valve and a finger trigger to actuate the gun valve;
a nozzle connected to the gun and comprising a head having a shaped opening;
a hose constructed and arranged to connect a cartridge outlet to the gun;
a hydraulic cylinder coupled to an end of the cartridge container, the hydraulic cylinder comprising:
a walled cylinder having an inside surface;
a piston in sealed slidable contact with the inside surface;
a plunger shaft coupled to the piston on one end and an opposing end of the plunger shaft being constructed and arranged to apply pressure against a plunger of a cartridge when a cartridge is mounted in the cartridge container;
a guide at an end of the walled cylinder in sealed slidable contact with the plunger shaft, an internal volume being defined by the walled cylinder and the guide, the internal volume having an upper volume and a lower volume separated by the piston;
respective liquid passages in the walled cylinder for allowing the passage of liquid to the upper volume and the lower volume; and
a liquid supply line for supplying pressurized liquid to the liquid passages.
Another aspect of the invention provides 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 the 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 the 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 the cartridge container, the hydraulic cylinder comprising a walled cylinder having an inside surface, a piston in sealed slidable contact with the inside surface, a plunger shaft coupled to the piston on one end and an opposing end of the plunger shaft being constructed and arranged to apply pressure against the plunger of the cartridge, a guide at an end of the walled cylinder in sealed slidable contact with the plunger shaft, an internal volume being defined by the walled cylinder and the guide, the internal volume having an upper volume and a lower volume separated by the piston, respective liquid passages in the walled cylinder for allowing the passage of liquid to the upper volume and the lower volume, and a liquid supply line for supplying pressurized liquid to the liquid;
connecting the liquid supply line to a source of pressurized liquid;
allowing a pressurized liquid to flow into the upper volume to apply pressure against the piston and move 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; and
actuating the finger trigger to permit the pastry dough, frosting or icing to be dispensed from the nozzle.
A further aspect of the invention provides a device for dispensing pastry dough, frosting or icing from a cylinder containing pastry dough, frosting or icing, the device comprising:
a frosting cylinder defining an internal chamber constructed and arranged to contain frosting, pastry dough or icing therein, the frosting cylinder having on an end a frosting outlet;
a hand-held gun having a gun valve and a finger trigger to actuate the gun valve;
a nozzle connected to the gun and comprising a head having a shaped opening;
a hose constructed and arranged to connect the gun to the frosting outlet;
a hydraulic cylinder coupled to an end of the frosting cylinder, the hydraulic cylinder comprising:
a walled cylinder having an inside surface;
a piston in sealed slidable contact with the inside surface;
a plunger shaft coupled to the piston on one end and an opposing end of the plunger shaft being coupled to a plunder which is constructed and arranged to slidably seal against the inner surface of the frosting cylinder;
a guide at an end of the walled cylinder in sealed slidable contact with the plunger shaft, an internal volume being defined by the walled cylinder and the guide, the internal volume having an upper volume and a lower volume separated by the piston;
respective liquid passages in the walled cylinder for allowing the passage of liquid to the upper volume and the lower volume; and
a liquid supply line for supplying pressurized liquid to the liquid passages.
Another aspect of the invention provides a method of dispensing pastry dough, frosting or icing from a frosting cylinder comprising:
inserting pastry dough, frosting or icing into a frosting cylinder defining an internal chamber constructed and arranged to contain frosting, pastry dough or icing therein, the frosting cylinder having on an end a frosting outlet;
coupling one end of a hose to the frosting outlet, another end of the hose being connected with a hand-held gun having a gun valve, a finger trigger to actuate the gun valve, and a nozz
