BACKGROUND OF THE INVENTION
It is known to cook food items using aluminum foil. The aluminum foil may be heated along with the food and disposed of thereafter. In many cases, the interior of the oven is not exposed to droppings or spattering as the foil provides adequate protection for collection of run-off, droppings and/or sputtering. However, frequently when cooking an item such as a pizza pie, the instructions indicate that the pie should be placed directly upon the grill in order that the crust be cooked in the proper manner. However, this exposes the grill and the area of the oven below the grill to spatterings or droppings from the cooked item.
Another problem with the conventional use of aluminum foil is that food items tend to stick to the surface of the aluminum foil, which may pose a problem when flipping the food item to ensure cooking on both sides.
Using the concept to a grill pan, when the juices of the food bring cooked are permitted to flow beneath the food, the results are improved, however, grill pans require cleaning and are limited in size and utility.
Moreover, nonstick chemicals are sometimes used to coat pans and/or foils to enable the easy removal of foods from the foil. Chemicals, particularly when subjected to high temperatures, may pose increase risks to the health of the user.
SUMMARY OF THE PRESENT INVENTION
A preferred embodiment comprises a food preparation device which provides a “grill like surface” while at the same time providing support for the food item, the easy removability of the food from the foil surface, and the disposability of foil. At the same time, by distancing the food from the flat surface of the foil, cooking is enhanced as air circulates beneath the food. And, in the case of foods which contain fat or oils, the oil or fat is evenly distributed beneath the food.
A preferred embodiment comprises a device for configuring foil comprising: a first portion comprising a first configuration; a second portion comprising a second configuration; the foil configuring device adapted to dispense foil between the first and second portions, the first and second portions imparting a configuration to the foil as the foil exits the dispensing device.
The present invention comprises producing a grill-like surface in a variety of ways.
In another preferred embodiment, the grill-like surface is provided by vertical supports which are supported by a substantially horizontal base. The vertical supports operate to produce a “grill like” surface for contact with the food item. This may be done, for example, by extending the foil over the vertical supports and then allowing the foil to enter into the gaps between the vertical supports. One way the foil enters the gaps between the vertical supports is by use of a device such as that shown as element 40 or 40A in FIGS. 9 and 10, which element 40 or 40A forms the foil within the space between the vertical supports 11 or 11A. The element 40 may extend for the width of the foil or may be somewhat shorter, as in the case of 40A. Optionally, the element 40A may have wheels 44 to facilitate movement during the formation of the grill-like surface.
In another preferred embodiment, the grooves in the foil are imparted by moving the foil relative to the grooving device or mechanism. Optionally, the grooving device or mechanism may be operatively associated with the package in which the foil is provided, such as that depicted in FIG. 15. This may be done as formations within the packaging or as an add-on to the package container, such as depicted in FIG. 23.
In an alternate embodiment, sets of groove forming wheels are cascaded relative to other sets.
A preferred method of creating a cross sectional configuration in foil comprises passing the foil through an opening; the opening having first and second portions which impart a configuration to the foil; the first and second portions being configured to create elevated portions along the longitudinal axis of the foil.
Another preferred method comprises passing the foil through wheel-shaped portions mounted on an axis having a somewhat diamond configuration which rotate on an axis.
Another preferred embodiment comprises a device for dispensing and configuration of foil comprising a first sections comprising first substantially circular portions; a second section comprising second substantially circular portions which interface the first substantially circular portions of the first section; a base on which the first and second sections are operatively connected; whereby when a foil is moved between the first and second sections, the foil is configured by the first and second substantially circular portions into continuously elevated portions along the longitudinal axis of the foil.
Optionally, the base forms part of a dispenser having a movable top portion for insertion of a roll of foil and wherein the first and second substantially circular portions are positioned on the side of the dispenser such that as the foil is dispensed, the foil passed between the first and second substantially circular portions to thereby configure the foil. Another option comprises interleaving the first and second substantially circular portions such that the first and second substantial circular portions are off-set from each other so as to produce one of ridges, undulations or serrations in the foil as the foil passes therebetween.
A further option comprises substantially circular portions comprising surfaces that are circular in cross section in a first plane and form an apex in a second plane perpendicular to the first plane. As an alternative option, each of the substantially circular first and second portions comprise surfaces that are circular in cross section in a first plane and form an oval in a second plane perpendicular to the first plane.
A further option is that the first and second substantially circular portions rotate on at least one first and second axles, respectively, and wherein the first and second substantially circular portions are adapted to pass foil therebetween in order to configure one of ridges, undulations or serrations along the longitudinal axis of the foil. Optionally, the substantially circular first and second portions pivot on at least one axle and that is motor driven. Optionally, the at least one axle comprises a plurality of axles separated spatially from one another in the longitudinal direction of the foil, and due to the spatially separated axles the inner portion of the foil is configured at a different interval of time than the outer portion of the foil as the foil is dispensed.
Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Thus, embodiments of the present invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
FIGS. 1-39 are schematic illustrations comprising selective components of “grill” creating systems. As used herein, the terminology “grill” refers to the feature of a cooking surface wherein only a portion of the full surface engages the surface of the food. The illustrations are merely exemplary. It is noted that the principles of the present invention may be utilized in connection with a foil or foil dispensing system, but are not necessarily limited thereto. Moreover, the invention is not limited to personal or home usage and may be used in corporate food processing, restaurant food processing or the like. As used herein, the term person refers to a person, company, organization, or group of persons. The foil configuring portions are interchangeable in the embodiments (or dispensers) disclosed and may be combined together in one dispenser.
FIG. 1 is a schematic illustration of a preferred embodiment comprising selective components of a grill provider device comprising vertical supports 11 positioned on a base 12. The length of the device, which would correlate to the horizontal direction as shown in FIG. 1, may be approximately twelve inches, 18 inches, twenty inches, or twenty-four inches to accommodate common foil widths. Similarly, the length of the device shown in FIG. 1 may be selected based upon the foil width, for example, 12, 18, 20 or 24 inches.
FIG. 2 is a front view schematic illustration of the preferred embodiment of FIG. 1. The vertical supports 11 may comprise a wire frame which extends around the perimeter as shown in FIG. 2 or may be a solid wall construction or a combination of the two. The material composition may be metallic if it is desirable to make it oven compatible and subject to oven temperatures or may comprise plastic, such as PVC if not subjected to high temperatures. Similarly, the base portion 12 may be of metal composition or plastic, such as PVC.
FIG. 3 is a side view of the embodiment of FIGS. 1 and 2. Although 7 vertical supports 11 are depicted in FIG. 3, the embodiment is not limited to 7 vertical supports and the number may be in a range from 2 to 30, depending upon the application and/or desired size.
FIG. 4 is a schematic illustration of another preferred embodiment comprising selective components of a grill provider device comprising vertical supports 11 positioned on a substantially round base 12. Although a circular base is depicted in FIG. 4, the base of the preferred embodiment may be rectangular, polygonal, elliptical, triangular, or any similar configuration. Also, the perimeter 21 may be a vertical wall similar in size to the vertical supports 11 or may optionally be omitted.
FIG. 5 is a schematic illustration of a preferred embodiment comprising selective components of a grill provider device 30 comprising vertical supports 11 positioned on a base 12. With respect to all of the embodiments disclosed in FIGS. 1-30, the material composition may be metallic if it is desirable to make it oven compatible and subject to oven temperatures or may comprise plastic, such as PVC if not subjected to high temperatures. Similarly, the base portion (for example 12) may be of metal composition or plastic, such as PVC. The height of the vertical supports may vary from one-quarter of an inch to one inch. However, a size of approximately 0.30 to 0.40 inches is preferred when adapted to be used as a foil template inasmuch as the support capability of foil may preclude higher heights when supporting food items. The spacing between the vertical supports may be similar to the spacing between grill wires, that is approximately one inch. For example, oven grill support wires of approximately one inch provide ample support for food items and allow a sufficient percentage of the food item to be exposed to convection currents within the over. Vertical supports 11 may be spaced in the range of ⅜″ to 1½″ apart; such that ample support is provided for the food item and at the same time, allow sufficient circulation of convection currents. The number of vertical supports 11 shown in FIG. 5 is four, but the invention is not limited to four supports, and the number may be in a range from 2 to 30, depending upon the application.
FIG. 6 is a schematic illustration comprising selective components of a grill provider device 30A comprising vertical supports 11 positioned on a base 12.
FIG. 7 is a schematic illustration of the preferred embodiment of FIG. 6 from a different perspective comprising vertical supports 11 positioned on a base 12. The component 30A may be used as a base support for the configuration of foil, as will be explained in further detail in the following.
FIG. 8 is a schematic illustration of the preferred embodiment top portion 40 comprising slots 41, 42 and 43. The top portion may be fabricated from plastic, such as PVC, or a metal, such as aluminum. The top portion 40 is adapted to fit over a bottom portion 30A. The top portion 40 pushes the foil into the region between the supports 11 to create vertical portions in the foil; i.e., a grill-like surface. Although the portions 45, 46 between the slots 41, 43 and 42 are somewhat rectangular, the portions may be arcuate, rounded or semicircular; as shown as 45A and 46A.
FIG. 9A is a schematic illustration of the preferred embodiment top portion 40 comprising slots 41, 42 and 43 positioned over a base portion 30A as depicted in FIG. 7. The top portion 40 may include a handle, not shown, to facilitate placement and removal of the top portion over the base portion 30A. Foil (although not shown in FIG. 9) may be placed in between the top portion 40 and base portion 30A so as to configure the foil with a grill-like top surface and allow drippings to be captured in the valleys between the top surface supports. Although a single use would impart three vertical supporting ridges correlating to uppermost segments 45, by repeatedly passing other portions of the foil though the top portion 40 and bottom portion 30A, any number of ridges may be impressed into the foil. The impression of multiple ridges by repeatedly impressing a piece of foil with the top and base portions 30A, 40 is depicted in FIG. 9B wherein a series of ridges 45A result from the impression of the segments 45. Although ridges 45A are shown in FIG. 9B, the foil may have a series of undulations or apices depending upon the configuration of the top and base portions 40 and 30A.
FIG. 10 is a schematic illustration of the preferred embodiment top portion 40A comprising slots 41, 42 and 43 and wheels 44 adapted to be positioned over a base portion. The technique illustrated in FIG. 10 extends the principles of the present invention to an embodiment wherein the top portion 40A covers only a portion of the base portion 30A. Wheels 44 may be provide to ease passage of the top portion 40A over the foil placed between the top and base portions in order to impart the configuration to the foil (as depicted in FIG. 9B).
FIG. 11 is a schematic illustration of a partial view of the top portion 40 comprising slots 41, 42 and 43 positioned above a base portion comprising a base 12 and vertical supports 11. The top portion need not be coextensive with the base portion 30A and may be moved to impart the desired configuration to the foil as depicted in FIG. 9B.
FIG. 12 schematically depicts a methodology associated with a preferred embodiment of the present invention in which foil is shown in conjunction with a base portion 30A comprising base 12 and vertical supports 11.
FIG. 13 schematically depicts a methodology associated with a preferred embodiment of the present invention in which foil is shown in conjunction with a base portion 30B comprising base 12 having multiple vertical supports 11; such as for example six. The material composition of the base section 30B may be metallic if it is desirable to make it oven compatible and subject to oven temperatures or may comprise plastic, such as PVC if not subjected to high temperatures. Similarly, the base 12 may be of metal composition or plastic, such as PVC. The height of the vertical supports may vary from one-quarter of an inch to one inch. However, a size of approximately 0.30 to 0.40 inches is preferred when adapted to be used as a foil template inasmuch as the support capability of foil may preclude higher heights when supporting food items. The spacing between the vertical supports may be similar to the spacing between grill wires, such as, for example, approximately one inch. For example, oven grill support wires of approximately one inch provide ample support for food items and allow a sufficient percentage of the food item to be exposed to convection currents within the over. Vertical supports 11 may be spaced in the range of ⅜″ to 1½″ apart; such that ample support is provided for the food item and at the same time, allow sufficient circulation of convection currents. The number of vertical supports 11 shown in FIG. 13 is six, but the invention is not limited to six supports, and the number may be in a range from 2 to 30, depending upon the application.
FIG. 14 is a schematic illustration of a partial view of the top portion 40 comprising slots 41, 42 and 43 positioned above a base portion comprising a base 12, vertical supports 11A and adjustable support 13. The adjustable support allows the user to vary the effective height of the supports 11A. When the top portion is lowered onto the foil which has been inserted between the top and bottom assembly 10A, the foil will initially supported by the top of the supports 11A and be driven to the support 13 location by vertical movement of the top portion 40. Consequently, the depth of the foil configuration is adjusted by the movement of the adjustable support 13 and corresponds to the distance “X” as depicted in FIG. 14. The distance X may be a distance in the range of one-eighth of an inch to one inch, depending upon the application. That is, a greater distance provides a deeper trough between vertical supports 11A allowing more heat flow between the vertical supports as a grill allows heat flow in the typical oven
FIG. 15A is a schematic illustration of a horizontal/adjustable support 13. The horizontal adjustable support 13 may comprise nodules 14 which engage adjustable grooves 15 for movable adjustment of the horizontal support 13. FIG. 15B is a schematic illustration of a vertical support 11A comprising, inter alia, adjustable grooves 15. Although only on vertical support 11A is shown in FIG. 15B, each vertical support 11A may have the same configuration to provide for engagement of the nodules 14 on the horizontal support 13. The invention is not limited to this type of adjustment means and a variety of adjustable supports may be utilized without departing from the spirit of the invention. For example, the resilient fingers 15A shown in FIG. 15C may be substituted for the adjustment grooves 15, such that the nodules 14 are supported between the resilient fingers and are movable for adjustment of the horizontal support 13.
FIG. 16 is a schematic illustration of a preferred embodiment of the present invention comprising a top portion 51 and a bottom portion 52 which may be integral with a dispenser for production of foil having a serrated edge (distance “Y” between the serrated top portions may be spaced from one-eighth to one inch). The distance Z as shown in FIG. 16 between the top and bottom serrated surfaces may be approximately slightly larger than the thickness of the foil to permit movement of the foil therebetween while at the same time configuring the foil in a serrated configuration as depicted in FIG. 16. The top and bottom serrated surfaces may be rounded to prevent tearing of the foil, depending upon the type of foil being used. Given that household aluminum foils products commonly have a thickness in the range of 0.01-0.018 mm, the distance Z may be approximately 0.02-0.03 mm.
FIG. 17A is a schematic illustration of a preferred embodiment of the present invention comprising a dispenser 60 which produces foil having a grill-like surface as depicted. Instead of the interface surfaces through which the foil passed in between having a serrated configuration, the configuration of the opposing surfaces is similar to a square wave, except that the upper portions 69A are smaller (not as wide) than the lower portions 69B to produce a grill-like effect. Providing a smaller surface area on the top portions 69A results in improved heat flow while cooking for better cooking of the bottom surface of the food item.
FIG. 17B illustrates various patterns which may be imparted to the foil by passing the foil through configurations resembling those shown in FIG. 17B. The patterns or configurations include a sine wave, modified square wave, serrated (or triangle) or saw tooth. Such configurations are merely exemplary and other configurations may be used without departing from the scope of the invention.
FIG. 18 is a schematic illustration of a preferred embodiment of the present invention comprising a dispenser 60 which produces foil having a grill-like surface as depicted comprising a top portion 61 and bottom portion 62 and further delineating the expanded view or cut-away portion or segment shown further in FIGS. 19 and 21.
FIG. 19 is a schematic illustration of a preferred embodiment of the present invention comprising a portion of the dispenser 60 comprising wheel-like portions 63 and 65, which rotate on axles 64 and 66 respectively (where the cut-away view of FIG. 18 is enlarged in FIG. 19). As the foil passes between the rollers 63, 66, the foil is shaped into a grill-like surface. Due to the horizontal width “H” of the wheels 63 relative to the width “K” of the wheels 65, a relatively small surface area (proportional to “K”) is in contact with the bottom surface of the food item while cooking, while the larger width “H” allows for heat flow between the elevated “K” portions to facilitate cooking of the bottom of the food item.
FIG. 20 is a schematic illustration of a side view taken along the lines 20-20 of FIG. 19. As shown in FIG. 20, the portion 61 is a wall of the dispenser 60 which supports the wheels 63 on the axle-like portions 64 to allow turning of the wheels 63 as the foil passes between the wheels 63, 65. Likewise, the portion 62 is a lower wall portion of dispenser 60 having an axle-like portion 66 for support of wheels 65 to facilitate rotation thereof.
FIG. 21 is a schematic illustration of a preferred embodiment of the present invention comprising a portion of the dispenser 60 comprising wheel-like portions 67 and 68, which rotate on axles 64 and 66 respectively (note that the cut-away view of FIG. 18 is enlarged in FIG. 21). As can be appreciated by those of ordinary skill in the art, the foil is configured with rounded trough areas resembling the shape of wheels 67 and crest portions resembling the configuration of the top portion of wheels 68.
FIG. 22 is a schematic illustration of a side view taken along the lines 22-22 of FIG. 21. As shown in FIG. 22, the portion 61 is a wall of the dispenser 60 which supports the wheels 67 on the axle-like portions 64 to allow turning of the wheels 67 as the foil passes between the wheels 67, 68. Likewise, the portion 62 is a lower wall portion of dispenser 60 having an axle-like portion 66 for support of wheels 68 to facilitate rotation thereof.
FIG. 23 is a schematic illustration of a preferred embodiment of the present invention comprising a dispenser 70 which surrounds the original store bought package of metallic foil.
