ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a 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 said 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 having a shaped opening, a hose constructed and arranged to connect the cartridge outlet to the gun,
a reversible electric motor removably coupled to an end of the cartridge container, the motor comprising:
a piston,
a shaft coupled to the piston to move the piston generally linearly in both forward and reverse directions, and
a switch structure to control operation of the motor,
whereby, when a cartridge containing pastry dough, frosting or icing is disposed in the cartridge container and the cartridge outlet is connected with the hose and when the motor is actuated, the shaft moves the piston and the piston engages the plunger thereby forcing pastry dough, frosting or icing to the gun, and actuation of the finger trigger permits the pastry dough, frosting or icing to be dispensed from the nozzle.
In accordance with another aspect of the invention, a method is provided 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 in a direction toward said cartridge outlet. The method includes:
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 reversible electric motor in a removable manner to an end of the cartridge container, the motor comprising a piston and a shaft coupled to the piston to move the piston generally linearly in both forward and reverse directions, the motor including switch structure to control operation of the motor,
actuating the motor to move the shaft and thus move the piston forwardly 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.
The present invention also 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 pastry dough, frosting or icing, 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, the nozzle having a head defining a shaped opening,
a hose constructed and arranged to connect the outlet to the gun,
a reversible electric motor removably coupled to an end of the frosting cylinder, the motor comprising:
a piston,
a shaft coupled to the piston to move the piston generally linearly in both forward and reverse directions,
a switch structure to control operation of the motor, and
a plunger coupled to the piston, the plunger being constructed and arranged to slidably seal against an inner surface of the frosting cylinder,
whereby, when pastry dough, frosting or icing is disposed in the frosting cylinder and the outlet is connected with the hose and when the motor is actuated, the shaft moves the piston and the piston forces the plunger against the pastry dough, frosting or icing thereby forcing the pastry dough, frosting or icing to the gun, and actuation of the finger trigger permits the pastry dough, frosting or icing to be dispensed from the nozzle.
The present invention also provides a method of dispensing pastry dough, frosting or icing from a device, the method comprising:
inserting pastry dough, frosting or icing into a frosting cylinder having an outlet;
coupling one end of a hose to the 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, the nozzle including a head defining a shaped opening;
coupling a reversible electric motor in a removable manner to an end of the frosting cylinder, the motor comprising a piston and a shaft coupled to the piston to move the piston generally linearly in both forward and reverse directions, the motor including switch structure to control operation of the motor, the piston being coupled to a plunger which is constructed and arranged to slidably seal against an inner surface of the frosting cylinder;
actuating the motor to move the shaft and thus move the piston forwardly to engage the plunger against pastry dough, frosting or icing disposed in the frosting cylinder 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 shaped head.
