Description

Title of Invention: A foldable and disposable tray for baking

Technical Field

[0001] The present invention relates to a foldable and disposable tray, and more particularly, to a tray for baking cakes pies and other baked or solidified goods. The foldable and disposable tray holds the mixture to be baked with provisions of automatic slicing the baked cakes in different shapes upon unfolding.

Background Art

[0002] Baking molds are structured to produce individual- or other sized baked goods. There are disposable, paper and aluminum foil baking molds that are structured to contain a quantity of batter and which are supported by a separate rigid mold, e.g. cupcake liners disposed in a muffin pan. Also in existence are paperboard containers for processing and handling a baker product having an embodied collapsible container in the form of a shallow rectangular tray of a size to accommodate a rather large sheet cake while it is prepared for baking, baked and fully processed. However, none of these baking molds have been adapted to be cut into consistent serving portions automatically, which the proposed invention attempts at.

[0003] To establish the uniqueness of the present innovation, a discrete survey of similar patents revealed the following:

[0004] US3771713 discloses a tray for pies such as pizza, fruit, meat or cream pies. The tray is divided into a number of equal size sectors by double partition walls, Individual tray sectors each containing a pie portion, can be removed from the remainder of the tray (and then thawed or heated individually) by cutting the tray along the tops of the partition walls. This enables baking the pieces when it is already divided and then it can be cut into pieces by cutting the tray itself. Yet there are two main problems 1. It is not suitable for a semi liquid baking mixture, furthermore cutting the pieces of the tray itself is very hard to do and especially when still hot or warm is even harder than cutting it with a knife.

[0005] US782544 describes a tray that meant for storing in piles one on top of the other but it couldn't be used for baking nor for cutting cakes for slices.

[0006] GB660912 teaches how to efficiently fold cardboard into partitions by having square holes in between thus it is not suitable for semi liquid materials nor made for baking.

Summary of Invention

[0007] An object of the present invention is to provide for an inexpensive, foldable shaped baking tray.

[0008] A still further object of the present invention is providing for a foldable shaped baking tray which is disposable.

[0009] It is still another object of the present invention to provide a means for the removal of individual baked goods’ slices or wedges from a disposable baking tray in such a manner that is quick and easy.

[0010] It is still another object of the present invention to provide a means for the removal of the individual slices of the baked item which does not destroy the integrity of the other plurality of slices in the baking container.

[0011] Another object of the present invention is to prove for a baking tray that does away with the problem of cleaning and storing the baking tray for reuse.

[0012] A still further object of the present invention is to provide for a baking tray that

consumes less space when stored before folding.

[0013] It is another object of the present invention to develop a round tray, a rectangle tray an English cake tray or any other shaped tray, that can be compacted and folded to form plurality of compartments ready for filling with the baking mixture.

[0014] Another object of the present invention is to have a baking tray hold the semi liquid baking mixture which upon baking can be expanded.

[0015] Still another object of the present invention is providing a cake tray, which upon stretching, slices the cakes into predefined sized and shaped slices, depending upon the cake tray design.

Detailed Description of The Preferred Embodiments

[0039] Referring to figures 1-20, but not limited to them, the inventive baking tray of the present invention can be used to bake, cool, serve, store or display any type of baked goods. It comprises a bottom and standing above it, walls that also act as partition walls to contain the cake molds for being cooked in the oven or cooled, served or stored.

[0040] The planar sheet may have any geometric shape, in either the compact or the

expanded configuration, that can be portrayed in two-dimensional and three-di mensional forms. The planar sheet, without limitation, can attain a square, rectangular, or with any configurations shape. Generally, the expanded configuration is in a two- dimensional geometric shape, with the compact configuration portrayed through a three-dimensional geometric shape. Further, the planar sheet may have one shape in the compact configuration, and a separate, distinct shape in the expanded con figuration. Usually, the sheet may be compartmentalized into multiple cuboids in the compact configuration, with the planar sheet when transformed into the expanded con figurations, forms plurality of rectangles or other geometric shapes. Likewise, the sheet may have the shape of a cube in the compact configuration, but a square shape or rectangular shape is formed when transformed into the expanded configuration. Alter natively an octagonal shape in expandable configuration can be transformed into multiples of prism like shape of the baked material in compact position.

[0041] The foldable and disposable baking tray of the present invention is configured out of a planar sheet of oven able material arranged in a compact configuration for delivery or shipment, storage. The said tray is capable of receiving the baking dough in compact position along with the plurality of compartments. As the tray is stretched and expanded after baking is complete, it renders slicing of the cake in small evenly and predefined sliced pieces, without the use of knife.

[0042] As is depicted in figures 1-22, the planar sheet of bake able material is shaped dif ferently when viewed in a stretched or expanded 2 Dimensional view (2D), than when the planar sheet is folded to attain a different shape in a 3 Dimensional view (3D). This depends upon the final shape of the slices of the cake/pie that is to be attained.

[0043] In the present invention, 4 different shapes have been described as different em

bodiments, they being rectangular, circle, square and triangular. However, with the same technique, many more geometric shapes could be designed.

[0044] In the first embodiment, a cuboidal shaped cake/pie is obtained after completion of the baking as can be viewed from figures 1-8.

[0045] In this embodiment and referring to figure 1, the planar sheet of paper is divided into a plurality of predefined shaped and distanced contours which when folded forms a box having a cuboidal or rectangular prism.

[0046] Further referring to figure 2 which is an enlarged view of a single contour of the planar sheet (10), comprises 4 panels of sheet lying opposite to each other, joined in between, with a middle rectangular portion (20). The panels namely, are a pair of first rectangular panels (1) and ( ) and a pair of second panels (2) and (2’). The said pair of first rectangular panels (1) and ( ) are further provided with folding lines (a) and (a’). The pair of second panels (2) and (2’) are provided in the middle with foldable lines (b) and (b’). These lines correspond with the edges, where the first two panels (1) and ( ) meet with the central rectangular planar sheet (20). These folding lines (a) and (a’) extends from one end of the first panel (1) to the end of the second panel ( ).

[0047] It is on these folding lines that the baking tray is folded vertically to each form a cuboidal shape of the baking product as can be referred to figures 2 to 6.

[0048] Further referring to figure 2, it can be observed that each of the corresponding panels (2) and (2’) joins with the next panel (2’) and (2) respectively. These are provided at their joining edges with foldable lines (c) and (c’) which abut to form the partition walls.

[0049] Also provided with the said pair of first panels is a pair of foldable side wings (4).

These wings help to fold and secure the pair of second panels (2) and (2’) with those of the pair of first panels (1) and (G), when these are folded vertically to form the cuboidal shape.

[0050] Referring to figure 1 and 5 to 7, the series of contours which when folded and

compacted forms a series of cuboidal compartments. However, to arrive at the object of the invention of expanding the sheet to provide predefined divisions of sliced cakes/ pies without manually slicing the cake, each of the contours (10) at extreme ends is provided with flaps (3) and (3’), which when stretched and with little application of pressure expands and separates the entire compartmentalized pieces of the cakes/ pie to be distributed.

[0051] Referring now to figures 8 to 15, the planar sheet is contoured to form a rectangular shape, as shown in figure 7, which when folded forms a plurality of square shaped compartments, to be filled by the baking dough.

[0052] The planar sheet as is depicted in figures 8 and & 9, forms a rectangular shape, which is divided into a plurality equal measuring squares (10). Each contoured square further, has a smaller concentric square (20) which lies inside the larger square (10). The smaller square is bounded by four equal foldable lines LM, MN, NO, OL which are folded and raised vertically to form walls for the compartment as is depicted in figure 11.

[0053] Considering the four comers of the inner square L, M, N. O and the four corners of the outer square R, S, T, U when the planar sheet is folded on the foldable lines LM, MN, NO, OL, it will be observed that the folds overlap at the comers, which is a hindrance for collective expansion of the entire folded and compartmentalized planar sheet.

[0054] To overcome the above drawback, the planar sheet along the lines RL, MS, NT and OU are folded inwards the planar sheet thereby abutting the planar sheet at lines M & M’ with M & M”. The same is repeated for all the corners of each of the squares or compartments of the planar sheet.

[0055] In each of the embodiments, the planar sheet is folded to form multiple or plurality of individual foldable expandable compartments which can be expanded once the baking is complete and the baked product is ready for serving. Alternatively, the baked product can be stored in the compartmentalized box and retrieved as and when desired.

[0056] In the third embodiment, as is depicted in figures 16 to 22, an octagonal shape having a plurality of compartments in the 2D view, which converts into 8 equal prism shaped compartments when folded is now hereby described.

[0057] Referring again to figures 16 to 22, the planar sheet for this embodiment is depicted in particularly in figure 14. When this planar sheet is folded it forms an octagonal shape wherein, the points (P) are all aligned centrally at one point as depicted in figure 18.

[0058] Describe a single section 10, of the foldable tray, the lines a, a’ are the foldable line which are folded vertically to form vertical panels which abut to form the inner partition walls of the foldable octagonal tray. The raised rim of the octagonal tray is denoted by (L) which is folded vertically to form the outer rim wall.

[0059] The sections (30) and (40) are formed by folding along the lines (b) and (b’) into a valley fold as in the art of origami. The said sections (30) and (40) are depressed to form cups for the baking batter to be filled in as is depicted in figure 19. As will be observed in figures 16 to 18, the two extreme ends of the contoured planar sheet are provided with lapels M & M’. These are provided to be used as connector when the planar sheet is folded into the compartmentalized octagonal shape as id depicted in figure 18 and 20. These lapels also serve as stretching and expanding means for stretching the compartmentalized planar sheet for retrieving the baked item when the baking is over and the baked item is to distributed to the consumers.

[0060] In some embodiments of the present invention, the planner sheet could be perforated in a manner that allows to remove each slice unfolded compartment with the slice, thus the cut compartment is used as a holder for the slice.

[0061] Thus it can be observed that the partitions or folds of the expandable planar sheet in the compact configuration provides boundaries between the baked items which later after baking, upon stretching transforms the baked item into predefined shaped and sliced items without the need of manual slicing.

[0062] It will be appreciated that numerous modifications and other embodiments can be devised by those of ordinary skill in the art. Therefore, it will be understood that the appended claims are intended to cover all such modifications and embodiments that come within the spirit and scope of the present invention
