This invention is a simple tool which relates generally to food preparation and presentation in a home or small kitchen. It comprises a simple tool which is used to form kitchen baking liner material into a shape having approximately flat bottom with fluted sidewalls. The formed perimeter shape could be traditional circular, or rectangular, or a star, or a heart, or an ellipse, etc. The resultant formed liner would be used in place of retail purchased pre-formed baking liners.
Conventional baking of individual serving baked goods such as cupcakes or muffins typically uses retail purchased, single use, fluted paper liners with circular perimeter. Retail baking liners were first produced in the early 1900's and are currently produced in factories using high volume production machinery. These factories have for a long time used a method to form liners in a machine generally described thus-placing baking liner material between forming tools consisting of a rigid hollow part with flutes on the interior and a second rigid part with flutes on the exterior. A machine presses the part with flutes on the exterior into the hollow part with flutes on the interior with the baking liner therebetween which forms the liner to have a flat bottom and fluted sidewalls. For a consumer, there is currently no kitchen tool they might purchase if they wish to form their own fluted liners. So, they must purchase retail packages of factory formed baking liners which are widely available at retail stores. The purchaser of these liners chooses from the limited color and printed pattern options available on the store shelf. Custom-printed retail liners may be specially ordered, but at additional cost. Almost all available retail baking liners are traditional circular or, less often, square perimeter. These retail liners are inexpensive, although a drawback is that baked goods tend to stick to the retail liners, particularly in gluten free baking.
In addition to single serving baking cups, bakers sometimes use baking liners when making a cake or larger baked item. They may just cut a shape to fit the bottom of their pan, or they use liner material larger than the pan and the weight of the batter pushes the liner material to the bottom of the pan and conforms the liner material to the sidewalls of the pan. The sidewalls in this instance likely experience excess liner which results in inconsistent, random overlapping of the liner material.
As an option to purchased baking liners, home bakers may alternately use a suitable size drinking cup and manually form liner material around it. Bakers use the drinking cup as a ‘mold’. This manual forming has somewhat inconsistent results and portions of the vertical walls overlap which partially or wholly distort or hide desired images pre-printed on the vertical sides of the liner. In this method, dimensions of the formed liner may be too large or too small depending upon the user's available drinking cup size.
One additional option for home bakers is to purchase reuseable silicone baking liners. These are more of an individual baking pan, generally not requiring the use of an actual cupcake pan. The problem with these silicone liners is that the baker must retrieve their silicone baking liners which can be difficult when used at a function outside the baker's home.
The unique invention herein improves the food preparation experience by providing a simple, lightweight, manually operated kitchen tool which the home baker may use to consistently form fluted baking liners out of the user's choice of baking liner material, (i.e., baking parchment paper, Quilon liner, wax paper, aluminum foil, etc.). This invention would be used to form kitchen baking liner material into a shape with approximately flat bottom and fluted sidewalls. In addition to traditional circular perimeter baking cups, embodiments of this invention may be constructed wherein the perimeter of the kitchen tool is a non-circular shape such as diamond or rectangle or star or heart or some other fun or geometric or non-geometric shape. This invention also provides the user with the option to customize the liner material or individually pre-color or decorate the liner material prior to forming.
The method of forming baking liner between rigid, fluted upper and lower tool pieces has over time become public domain. The invention herein is inclusive of the described physical hand tool for use in home kitchens. This invention has two embodiments where the method of use embodies a flexible or hinged tool feature. All embodiments of this baking liner forming tool herein are included in this same specification as they all produce the same result-they are all used to manually form baking liner material.
The drawings accompanying and forming part of this specification are included to depict aspects of the invention and are not deemed to be all-inclusive. A person versed in the art may design a similar tool which appears different yet performs this same function. Embodiments illustrated in the drawings refer to the exemplary, and therefore nonlimiting, where like numerals are used to refer to like. The features illustrated in the drawings are not necessarily drawn to scale.
It is noted that the unformed liner material represented in the drawings is illustrated as circular or rectangular, but that is entirely the discretion of the user. They may decide to cut a circular shape or fanciful shape or simply tear the liner to approximate size.
This invention specification describes five embodiments. The formed liner resulting from each embodiment of the invention is similar, although there will be minor variations in resulting formed liner dependent upon which embodiment is used in forming the liner material. The resultant baking liner has roughly flat bottom and fluted sidewalls. It may have a circular perimeter or some other perimeter such as, but not limited to rectangular, elliptical, star shape, heart shape, etc. The invention may be scaled in size larger or smaller depending upon the desired size of the finished liner. In addition, for a given size tool of this invention, the user may vary the liner's sidewall height by using larger or smaller pieces of baking liner material.
Prior art in the public domain is the method of making cupcake liners through forming baking liner material between some fashion of rigid, fluted upper and lower tools or apparatus. This same method of use is used by home bakers forming baking liner between two drinking cups. The new art defined in this specification is the physical kitchen tool which uses this same method of operation from the public domain.
It is noted that the two kitchen tool embodiments which use flexible or hinged apparatus are using new art for the method of use and also new art for the physical kitchen tool.
Overview of the embodiments of the invention presented herein:
Images representative of described forming methods generally illustrate traditional circular profile of the liner material, but in all these embodiments, the baking liner material may be formed to a non-circular perimeter profile such as a rectangle, oval or ellipse, heart, star, etc.
Describing the physical tool in this embodiment, the outside perimeter of the top tool 1 is in the form of a truncated cone with vertical ribs 3 spaced around the outside perimeter as illustrated in
Employing this embodiment to form baking liner material, the user employs hand pressure to push the top tool 1 against the unformed liner material 10 as illustrated in
Describing the physical tool comprising this embodiment, the top tool 7 is roughly a truncated cone with a side A 9 and side B 11. Each side has vertical ribs 12 & 13 around the outside profile. The ribs 12 on side A 9 are at a radially wide angle suitable for initial preforming of the liner material 10 against the ribs 14 of the bottom tool 8. Side B 11 of the top tool 7 similarly has raised ribs 13, however they are at a longitudinally much steeper angle for properly forming the final profile of the liner material 30 against the ribs 14 of the bottom tool 8. The bottom tool 8 is a hollow funnel shape and has vertical raised ribs 14 (or raised surfaces) on the inside perimeter. These ribs 14 on the bottom tool 8 interface with the top tool 7 to form the final profile of the liner material 30.
To use this tool resulting with the formed baking liner material 30, the user centers the unformed liner material 10 on bottom tool 8. Then user takes the top tool 7 and approximately centers side A 9 on the liner material 10 which is resting on the bottom tool 8. The user presses with hand force on top tool 7 side A 9 against the liner material 10 on top the bottom tool 8. This serves to preform the liner material 20. The user may need to wiggle or slightly rotate top tool 7 side A 9 approximately +/−5 degrees to get top tool 7 side A 9 to make a preform of the baking liner material 20. Representation illustrated in
The user then keeps the preformed liner material 20 in preformed position on the bottom tool 8 while lifting and inverting the top tool 7 to side B 11. The user then places top tool 7 side B 11 against the preformed liner material 20. The user approximately aligns ribs 13 of the top tool 7 side B 11 with the indented, preformed liner material 20. The user presses the top tool 7 side B 11 against the preformed liner material 20, then pushing it into the bottom tool 8. As the top tool 7 side B 11 is pressed into the bottom tool 8, the ribs 12 and valleys of the top tool 7 will tend to self-align with the ribs and valleys on the bottom tool 8 for proper final forming of the liner material 30. Dependent upon the way the tool is designed to operate, the user may need to continue pushing the top tool 7 side B 11 into the bottom tool 8, eventually lifting the whole assembly from the flat surface. In this use case, the user would continue pressing the top tool 7 side B 11 through the bottom tool 8 until the final formed liner material 30 comes out the bottom of the whole assembly. This is represented in
Describing the physical tool in this embodiment, the preform tool 17 is a hollow, truncated cone shape with radial ribs 19 around the underside perimeter of the tool 17. These ribs 19 are sized and spaced to correspond with the forming ribs 21 on the bottom tool 18. The ribs on the preform tool 17 are angled downward from horizontal so as to conform to the lead-in on the ribs 21 of the bottom tool 18. Material on the preform tool 17 between these ribs 19 is removed so as to allow the flutes of the preformed liner material 20 to flex upward during preform and subsequent forming operation. The top tool 16 is the approximate shape of a truncated cone or cylinder having vertical ribs 22 around the outer circumference which align between the ribs 21 on the bottom tool 18 and also align to the inside diameter of the preform tool 17. The bottom tool 18 is a hollow funnel shape and has raised ribs 21 conforming to the preform tool 17 and top tool 16 which form the liner material 10. The specific profiles of the ribs 22, 19, and 21 are determined through mathematical analysis or by trial and error or through some combination thereof.
To use this embodiment of the invention to form the liner material, the user places the bottom tool 21 on a flat surface with the desired un-formed liner material 10 centered on top. The user next places the preform tool 17 approximately centered on top of the liner material 10 which is resting on the bottom tool 18. The user presses downward on the preform tool 17 to start forming the liner. The user may need to wiggle or rotate pre-form tool 17 +/−5 to 10 degrees while simultaneously pressing downward to get the preform tool 17 to make the preform of the liner material 20. By design, the preform tool 17 will self-orient to the raised ribs on the bottom tool 13. A representation of this is shown in
The user continues holding the preform tool 17 in place on the bottom tool 18 along with the now preformed liner 20. The user keeps the preform tool 17 in place and then places the pusher tool 16 in the center of the preformed liner material 20. The pusher tool 16 will align to the inside perimeter of the preform tool 17. At this point in the process, both preform tool 17 and preformed liner material 20 are resting on the bottom tool 18. The user pushes downward on the pusher tool 16, continuing with a retaining downward force on the preform tool 17. As the pusher tool 16 presses the preformed liner material 20 into the bottom tool 18, the ribs on the pusher tool 16 will self-orient to the inside diameter of the preform tool 17 and also to the ribs on the bottom tool 18. This is represented in
Depending upon the design of this embodiment, once the pusher tool 16 is pressed downward until it touches the flat surface, The user may need to lift the whole assembly while continuing to push the pusher tool 16 through the bottom tool 18 until the formed liner 30 is pushed out the bottom of the assembly. This is represented in
Describing the exemplary physical tool comprising this embodiment, the pusher tool 23 is a truncated cone with separated ribs 26 vertically around the outside perimeter. These ribs 26 have a flexible hinge 27 where each rib 26 connects to the middle part of the top tool 23. In the other option, the pusher tool 24 is a slightly different design wherein the vertical ribs 29 are connected to each other and to the middle part of this top tool 24 by some sort of hinges 35. There are many possible configurations of each bottom tool 25 or 28. Representations of two possible configurations are illustrated in
To use this embodiment, The user would place the bottom tool 25 or 28 on a flat surface. The user then places the baking liner material 10 approximately centered on top. The user then places the corresponding pusher tool 23 or 24 approximately centered on top of the liner material 10 which is resting on top of the bottom tool 25 or 28. The user then begins pushing the pusher tool 23 or 24 downward, into the liner material 10 and hence into the respective bottom tool 25 or 28. This will start forming the liner material 20 as represented in
The tool represented here might also be designed using some type of spring arrangement to apply outward force to the ribs 26 or 29. (Spring arrangement not illustrated in this specification).
Describing the physical pieces comprising this embodiment, the top tool 36 is a truncated cone having vertical ribs 39 around the exterior perimeter. The flexible middle tool 37 is a truncated cone with ribs 40 around the inside perimeter. The ribs 40 in the flexible middle tool 37 may be pointed as shown in the representative figures or rounded or another profile which properly flexes to form the liner material 10. The flexible middle tool 37 has thin sidewalls or some other configuration to allow the flexible ribs 40 to move inward and upward as they form the liner material 10. The flexible middle tool 37 ribs 40 comprise hinged seams 41 which flex or bend. This allows the ribs 40 to have relative motion during tool use. The base 38 is a hollow cylinder comprising a chamfer or radius or some combination which forms the top inside perimeter. In use, the interior, curved top of the base 38 acts against the outside of the ribs 40 of the flexible middle tool 37, compressing the ribs 40 which interface with the ribs 39 on the top tool 36 to form the final shape of the liner material 30.
To use this embodiment of the invention the user places the base 38 on a flat surface. Next the user places the flexible middle tool 37 approximately centered on the base 38. Then the user places the unformed liner material 10 approximately centered on the flexible middle tool 37. The user then places the top tool 36 approximately centered on the liner material 10. This step is represented in
