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 users 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 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 the following. Provided is a novel device for applying frosting or icing to a cake or pastry from a cartridge containing pastry dough, frosting or icing comprising:
a walled cartridge container defining at least one internal chamber 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 the at least one air inlets for separately controlling air pressure applied to each of the 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 for dispensing pastry dough, icing or frosting;
an associated hose connecting each of the outlets to an associated gun valve in the hand-held gun; and
a finger trigger on the hand-held gun connected to the gun valve whereby when the finger trigger is activated the gun valve opens allowing the flow of pastry, icing or frosting through the hand-held gun.
Also provided is a novel device for applying frosting or icing to a cake or pastry comprising:
a tube defining side walls of a compressed air chamber;
a cap constructed and arranged to seal an end of the tube and define a top of the compressed air chamber;
a plunger rod disposed within the tube;
a sealing washer connected to the plunger rod and being constructed and arranged to provide an air seal with an inside surface of the tube and to slide along the inside surface, the sealing washer defining a lower wall of the lid compressed air chamber;
an air inlet in the cap or the tube located to allow air into the compressed air chamber;
valve structure associated with the air inlet for controlling the air pressure in the compressed air chamber;
a container lid connected to a lower portion of the tube, the plunger rod extending through the container lid;
a plunger connected on an end of the plunger rod on a side of the container lid opposite the tube;
a container body having an opening that seals with the container lid and a container outlet in a portion opposite the opening;
a hand-held gun for dispensing pastry dough, icing or frosting;
a hose connecting the container outlet to a gun valve in the hand-held gun; and
a finger trigger on the hand-held gun connected to the gun valve whereby when the finger trigger is activated the gun valve opens allowing the flow of pastry, icing or frosting through the hand-held gun.
The invention also provides a novel method of applying pastry dough, icing or frosting 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 the cartridge and contain pressurized air, each internal chamber having an associated air inlet and an outlet, a valve structure associated with each of the at least one air inlets for separately controlling air pressure applied to each of the 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 the hand-held gun, and a finger trigger on the hand-held gun connected to the gun valve whereby when the finger trigger is activated the gun valve opens allowing the flow of pastry, icing or frosting through the hand-held gun;
adjusting the air pressure in the inner chamber containing the cartridge to a level sufficient to force the pastry dough, icing or frosting through an outlet in the cartridge, through the outlet in the inner chamber, though the hose and to the hand-held gun; and
applying pressure to the finger trigger to cause flow of the pastry dough, icing or frosting through an outlet in the cartridge, through the outlet in the inner chamber, though the hose and through the hand-held gun.
The invention further provides a novel method of applying pastry dough, icing or frosting comprising:
loading pastry dough, icing or frosting into a container body of a device comprising:
a tube defining side walls of a compressed air chamber;
a cap constructed and arranged to seal an end of the tube and define a top of the compressed air chamber;
a plunger rod disposed within the tube;
a sealing washer connected to the plunger rod and being constructed and arranged to provide an air seal with an inside surface of the tube and slide along the inside surface, the sealing washer defining a lower wall of the compressed air chamber;
an air inlet in the cap or the tube located to allow air into the compressed air chamber;
valve structure associated with the air inlet for controlling the air pressure in the compressed air chamber;
a container lid connected to a lower portion of the tube, the plunger rod extending through the container lid;
a plunger connected on an end of the plunger rod on a side of the container lid opposite the tube;
the container body having an opening that seals with the container lid and a container outlet in a portion opposite the opening;
a hand-held gun for dispensing pastry dough, icing or frosting;
a hose connecting the container outlet to a gun valve in the hand-held gun; and
a finger trigger on the hand-held gun connected to the gun valve whereby when the finger trigger is activated the gun valve opens allowing the flow of pastry, icing or frosting through the hand-held gun;
connecting the container body to the container lid;
