The present invention is directed towards a simple, hand-held, disposable device used to decorate and enhance the presentation of food; particularly towards a device which creates decorative shavings of food items of a desired thickness and curl; most particularly to a device that creates decorative shavings of food items of a uniform, aesthetically pleasing design while being able to retain and store any unshaved portion of the food item therein.
There is often a desire to enhance the appearance of food items for human consumption, especially on notable occasions (holidays, birthdays, weddings, etc). Careful control of color, surface texture and physical arrangement of edible objects can enhance the appeal of the food item. Often, various toppings are added to food items so that they are more appealing to the eye.
For example, chocolate is one of the most popular food items used to embellish and enhance the flavor of desserts (cake, truffles, ice cream, etc). Sometimes the chocolate is applied in the form of thin flakes, ribbons or shavings. Currently, if one wishes to decorate a food using chocolate shavings, two options exist. First, one may purchase and use pre-shaved chocolate. Typically such chocolate is bulk packaged in plastic bags. However, a number of significant problems typically arise when using pre-shaved chocolate to decorate food items. The delicate nature of the chocolate shavings means that the shavings do not readily survive packaging and transport. Frequently, a significant portion of the packaged shaved chocolate is broken into small pieces and fines before it can be utilized by the end-user. Secondly, the relatively large surface area of the chocolate shaving to its mass invites degradation from the atmosphere by oxidation and humidity. Additionally, thin chocolate shavings are very sensitive to melting and/or “blooming” since these shavings have relatively low thermal mass and are readily warmed upon exposure to elevated temperatures.
Another option available to one wishing to decorate with chocolate (or similar food products) requires the use of a sharp knife, peeler, or grater to create the desired shavings. It may also be necessary to warm the chocolate so that the knife or peeler will perform satisfactorily. Considerable skill is required to produce the thin, delicate shavings or curls which are most often desired. Frequently, the knife or peeler will dig into the chocolate too deeply. This discontinuous action of the blade against the food product results in irregular shards or partial curls and production of “fines,” which are generally less desirable than uniform curls.
Further, chocolate has a relatively high yield strength and considerable force is often required to force the knife or peeler blade through the chocolate. Moreover, it is difficult to hold the piece of chocolate to be shaved as heat from one's fingers causes the chocolate to melt and become slippery. Further difficulty is encountered if the chocolate bar to be shaved is small, making an adequate grip difficult. This can create a dangerous situation as the blade of the knife, peeler or grater comes ever closer to the user's hand holding the chocolate. Many cooks have at one time or another accidentally sliced their knuckles using a grater to grate foods.
Additional problems often arise when attempting to grate or shave chocolate from a hand held chocolate bar as the sufficient amount of shavings have been generated but some of the chocolate bar remains. Unless the remaining unshaved portion is wasted, a means of packaging and storing must be devised for this unused portion so that it can be saved for future use. Lastly, any of the tools used to generate the shavings must be cleaned and stored for future use.
There are numerous commercially available food-processing devices and storage container systems for grating, slicing and crushing food items. However, many of the designs found in the prior art make no attempt to precisely control the feed rate of the food to be processed with respect to the cutting motion of the blade(s). Most of these designs rely on manually applied force by the user to urge the food product into contact with the moving blade. Such means cannot be relied upon to produce uniform, aesthetically pleasing shavings or curls. Indeed, most prior art devices are not able to produce shavings or curls but rather only generate irregular granules, flakes or powder.
For example U.S. Pat. No. 6,409,107 to Romano discloses a hand-held food processor for grating garlic or the like in which a reciprocating flat blade is forced across the face of a food product. The feed rate of the food into the cutter blade is dependent upon the force manually applied by the user.
U.S. Pat. No. 5,226,353 to Hanson describes a machine for forming chocolate spiral shavings. This machine is powered by electric motors and utilizes a reciprocating blade action to produce chocolate shavings. The machine is of an industrial type and is not intended to be hand-held.
U.S. Pat. No. 5,071,663 to Dugan discloses a cheese grater and package in which the grater device also provides a storage receptacle for the cheese contained therein. Again, the rate of feed of the cheese product into the grater blade is dependent on the application of manual force by the user. Since the product is intended to produce gratings of indeterminate shape and not delicate curls, this means of feeding the cheese into the grating blade is sufficient.
U.S. Pat. No. 936,101 to Edwards teaches a reusable soap granulator intended to grate bars of soap. This device employs a feeder screw mechanism to force a bar of soap into a grating blade assembly. Unlike the present invention, this prior art device uses a toothed blade to granulate the soap, and is incapable of producing decorative shavings. Additionally, this device is to be reused by opening and disassembling the device by the user so that it may be reloaded with soap, thereby exposing the user to the toothed arm and possible injury.
U.S. Pat. No. 4,127,375 to Nelson describes a re-loadable dispensing device for producing a plurality of uniform dough masses. The device employs a hand operated crank to extrude and cut the dough into masses. A feed screw forces the dough through an extrusion plate whereupon it is cut into pieces by a rotating flat blade.
U.S. Pat. No. 3,552,460 to Cooney describes an apparatus for cutting blocks of chocolate and the like. The device comprises a tubular housing having fixed blades, a rotatable, non-cylindrical barrel and a follower for urging a block of material into contact with the blades. No means of controlling the feed rate is provided other than manual application of force by the user.
U.S. Pat. No. 1,025,513 to Craven describes a receptacle for containing and discharging solid and semisolid substances. The device of this invention employs a feed screw to advance the material to be grated into a blade, which rotates relative to the material to be grated. Disclosed is the fact that the device can be used to reduce chocolate to a fine condition, not distinct shavings.
U.S. Pat. No. 4,082,230 to Steinko describes a cheese grater and container. In this device a reversible blade/cover assembly is employed to either cover the food product in the container or, alternately, to grate the product. The force applied by the user determines product feed into the grater blade.
While the foregoing described prior art devices have advanced the art in a variety of ways, there nevertheless remains a need for an improved food processing device to produce delicate shavings, curls and other interesting shapes from food items, particularly chocolate or the like, which is economical to manufacture, simple to assemble, and permits the consistent production of uniformly reproducible decorative food products by individuals of average skill, in a safe, effective and economical manner.
While the use of food items, such as chocolate shavings to embellish the appearance and flavor of foods such as cakes and the like was known, prior to the instantly disclosed invention there was no adequate means in the art by which one could effectively utilize commercially prepared shavings, nor a process of producing one's own shavings using conventional means.
Accordingly, it is the principle objective of this invention to provide a convenient, simple and safe means to produce decorative, reproducible and precise shavings of a food item on demand, while simultaneously providing a sanitary and convenient storage receptacle for any unshaven portion thereof. Because the shavings are produced at the time of use, the aforementioned problems of oxidation, moisture degradation, melting, and production of undesirable fines are substantially reduced.
It is a further object of this invention to disclose a device wherein the food item to be shaved is securely held in place relative to the motion of the cutting blade and, since the feed rate of the food product relative to the rotation of the blade is precisely controlled, precision shavings result, requiring little skill by the operator.
Still another objective of this invention is to disclose a device wherein the user's fingers are not in contact with the food to be shaved, such that body heat is not transferred to the food causing it to melt.
Another objective of the present invention is to disclose a device wherein the cutting blades are safely contained therein such that there is little possibility of injury to the end user.
Yet still another objective of this invention is to provide for increased sanitation since the user's fingers never come in contact with the food product.
An additional object of the instant invention is to teach a means wherein the bulk of the food item is substantially sealed from the atmosphere, thereby substantially reducing degradation.
Another objective of the instant invention is to provide a device that is economical to manufacture in that it has few components or complicated moving parts.
Yet an additional objective of the instant invention is to provide a device that is easily assembled, and which, once assembled, is reliable and resistant to disassembly.
Other objectives and advantages of this invention will become apparent from the accompanying descriptions taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof. It will be readily appreciated by those skilled in the art that the use of a simple, hand-held, disposable apparatus for creating decorative slices of food items is highly effective and useful in the culinary art.
The following list defines terms, phrases and abbreviations used throughout the instant specification. Although the terms, phrases and abbreviations are listed in the singular tense the definitions are intended to encompass all grammatical forms.
As used herein, the term “food item” refers to any edible item, which may be desirous to obtain in the form of a decorative shaving. Non-limiting examples of suitable food item include chocolate, nougat, caramel, butter, toffee, meat, cheese, dough, nuts, fruit, vegetable, marzipan, pet food and combinations thereof.
As used herein, the term “shaving” is used to denote the formation of a single continuous segment of the food item obtained from a single stroke of the cutting means across the food item. Different configurations of shavings include, albeit not limited to, helical, spiral or telescopic type curls, and relatively flat, uncurled ribbons.
Detailed embodiments of the instant invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific functional and structural details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
Referring now to
The container 12 is comprised of a generally cylindrical tube with an enclosed first end. The second end of the container 12 and end-piece 16 are operatively engaged in a manner effective to provide unidirectional rotation of the end-piece relative to the longitudinal axis of the container. For example, as seen in the preferred, albeit non-limiting embodiment shown in
As illustrated in
As illustrated in
As shown in
The space between food item 30 and the interior walls of container 12 is kept to a minimum leaving just enough annular space for the food item 30 to be advanced along the longitudinal length of container 12. This ensures that the food item 30 is securely held in place and its alignment relative to the central longitudinal axis is maintained with respect to the rotation of the cutting means. The intimate rotational and longitudinal interaction of container 12 with end-piece 16 and cutting means 20, should be such that there is minimal opportunity for wobble or chatter of the food item 30 when the device is operated. Thus, the annular support 36 may be employed to maintain the relative position of the food item 30 stable.
As illustrated in
It is contemplated by the instant invention to provide shaver assemblies that produce shavings of varying thickness. This may be accomplished, e.g. by providing a shaver assembly having a rod 40 with a relatively coarse pitch and/or reducing the number of blades 20 acting on the food item 30. Additionally, it is contemplated to provide an assembly that creates different configurations of shavings (e.g. helical curls, spiral curls, ribbons, etc). This may be accomplished by varying the shape of the end-piece, e.g. the angles created between the cutting means 20 and the longitudinal axis of the food item 30.
In operation of the above mentioned embodiment illustrated in
Referring now to
Like the aforementioned embodiment, the threaded rod 40′ transverses the follower 28′ through a corresponding threaded aperture 37′ and is non-rotatably attached to the end-piece 16′ to form the complete assembly 10′ (
Referring now to
As shown in
In operation when rotational force or torque is applied to the knob 15′ by the user, the force is transferred down the rod 40′ to the end-piece 16′. The rotation of the rod 40′ causes the follower 28′ to translate relative to the longitudinal axis of the threaded rod 40′, but the engagement means does not allow the follower 28′ to rotate about longitudinal axis. The food item 30′ is moved at a predetermined rate toward the end-piece 16′ and into contact with the blade 20′ and the shaving 45′ produced by the blade 20′ is expelled through at least one window 18′, as shown in
By permanently connecting one end of the threaded rod 40′ with the end-piece 16′, it is possible to synchronize the downward longitudinal movement of the follower 28′ along the threaded rod 40′ upon rotation of the knob 15′. This synchronized timing between the movement of the follower 28′ and the end-piece 16′ provides a predetermined amount of food item 30′ to encounter the beveled edge of the blade 20′ positioned in the end-piece 16′.
With any of the abovementioned embodiments, a plurality of blade/window combinations may be employed as desired. The use of additional blade/window combinations located radially along the end-piece 16, 16′ permits multiple shavings to be produced simultaneously (
Preferably, the food item 30, 30′ is pre-packaged by the manufacturer within the interior space created between end-piece 16, 16′ and a follower 28, 28′. The pre-packaged food item 30, 30′ is generally shaped similar the interior of the container 12, 12′ and has an interior bore running its entire length (e.g. preformed). As shown in
In a preferred, albeit non-limiting embodiment, the follower 28, 28′ is a polygonal shape and the end of the food item 30, 30′ in contact with the follower 28, 28′ is shaped to mate with the follower 28, 28′ such that the force acting transferred to the food item 30, 30′ by the follower 28, 28′ may be effectively distributed so as to prevent damage to the food item 30, 30′. The general shape of follower 28, 28′ should be such that it substantially corresponds with the frustoconical shape of end-piece 16, 16′ in order for essentially all of the food item 30, 30′ to be utilized with minimal waste. Furthermore, the follower 28, 28′ can include teeth (not shown), as disclosed in U.S. Pat. No. 5,071,663 to Dugan (previously incorporated by reference), that can penetrate the top of the food item 30, 30′ to effectively grip the food item 30, 30′ such that the food item 30, 30′ does not wobble or chatter as it is being shaved. If the food item is permitted to wobble significantly during the shaving action, the form of the shavings or curls may suffer.
In another preferred embodiment, the peripheral edge of said follower 28, 28′ can be provided in substantially fluid-tight contact with the sidewall of the container 12, 12′ to preclude passage of said food item 30, 30′ past the peripheral edge of said follower as the follower advances along the longitudinal axis of said container. The peripheral edge of the follower 28, 28′ can include a disc seal (not shown) as disclosed in U.S. Pat. No. 4,714,205 to Steinko (previously incorporated by reference) or a resilient O-ring (not shown) housed within a notch on the periphery of the follower 28, 28′, as disclosed in U.S. Pat. No. 4,127,375 to Nelson (formerly incorporated by reference).
Additionally, a cap 22, 22′ (shown in
All of the components of the assemblies 10, 10′ may be made from plastic resin, metal or any other suitable material. The cutter blades may be fabricated of a suitable plastic and may be part of end-piece 16, 16′ or the blades may be made of metal, ceramic or other suitable material and attached to end-piece 16, 16′ by any means known in the art (e.g. adhesive, welding, etc). For example, the device may be fabricated out of clear plastic or by incorporating windows such that the amount of the food portion remaining is visible to the user. Additionally, other means known in the art may be provided to inform the user of the remaining portion.
The length, diameter or other dimensions of the pre-packaged food item may be varied as desired. The geometry of the food item may be irregular so as to produce irregular shavings. Likewise, modifying the shape of the blade 20, 20′, for example, saw-shape, sinuous, etc, can produce irregular shavings or curls. Moreover, the assembly 10, 10′ can be pre-packed with two or more varieties of food into a single food item, for example, white chocolate and dark chocolate, so that striped or checkered shavings can be produced by the device of the instant invention.
It was discovered by the present inventors that the end-piece 16, 16′ could be formed such that the angle 23 (e.g. angle of attack) created between the chamfered tip of the blade 20, 20′ and the tangent formed from the food item 30, 30′, as seen along the plane transverse to the longitudinal axis of the food item 30, 30′, dictate the degree or “tightness” of curl produced, as seen in
Additionally, as illustrated in
Moreover, it has been realized by the present inventors that certain food products with a certain shaving thickness appear more pleasing and offer a better mouth-feel than others. For example, shavings in the range of approximately 0.001 inches to 0.03 inches thick have a very good mouthfeel in that they melt instantly in the mouth. However, shavings thinner than 0.001 inches, while having good mouth-feel, are generally incapable of supporting their own three-dimensional shape.
The thickness of the shavings produced by the instant invention can be varied by controlling the relative rate of feed of the food item into the rotating blade(s) 20, 20′ with respect to the number of blade revolutions. For example, if the feed rate of the food item 30, 30′ is increased per revolution of the blade(s), then thicker shavings will result. Similarly, if the number of blades are increased, with no change in feed rate per revolution of the end-piece 16, 16′, then the shavings produced will be thinner than those produced by fewer blades.
Furthermore, thicker shavings can be created using a relatively coarse pitch (i.e. number threads per inch) for the threaded rod 40, 40′ and/or reducing the number of blades 20, 20′ acting on the food item 30, 30′. It has been found that using a softer food item such as “tropical” chocolate, or food at an elevated temperature, shavings may be effectively produced which are 0.030 inches thick or even thicker, the preferred thickness for shavings is between about 0.003 inches and about 0.030 inches thick. Thus depending on the food item to be shaved, the assembly 10, 10′ can be pre-packaged with a rod/blade configuration that will generate thick or thin shavings depending on the desire of the consumer. In one preferred embodiment the threaded rod 40, 40′ comprises a stainless steel rod of No. 4 diameter with 40 threads per inch and two cutter blades 20, 20′ were employed. This configuration yields shavings with a thickness of approximately 0.0125 inches.
It is to be understood that while a certain form of the invention is illustrated, it is not to be limited to the specific form or arrangement herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification.
One skilled in the art will readily appreciate that the present invention is well adapted to carry out the objectives and obtain the ends and advantages mentioned, as well as those inherent therein. The various apparatus, methods, procedures and techniques described herein are presently representative of the preferred embodiments, are intended to be exemplary and are not intended as limitations on the scope.
