The invention relates generally to layer cutting assemblies. More particularly, the invention relates to a layer cutting tray and sleeve apparatus for allowing a user to slice layers of baked goods accurately and evenly.
During the commercial preparation of food products, especially products for the bakery or foodservice industries, it is often desirable to cut a cake or other product into some predetermined form or shape. For example, in the case of frozen cakes, it is common for a commercial kitchen or bakery to employ hand laborers to slice the cakes into layers for further decorating or sale.
In many kitchens, a large knife is used to separate frozen cakes into layers. This technique is labor intensive and often requires extreme care to avoid injuries to kitchen personnel. Forming layers with a knife also requires a certain level of skill to ensure the layers are visually appealing.
In view of the considerations outlined above, a variety of cutting assemblies have been developed to separate cakes into layers. Known prior art includes U.S. Pat. No. 2,589,911; U.S. Pat. No. 3,277,754; U.S. Pat. No. 4,213,241; U.S. Pat. No. 2,964,844; U.S. Pat. No. 817,027; and U.S. Pat. No. Des. 363,870. While these devices fulfill their particular objectives and requirements, the aforementioned devices are large and cumbersome. Accordingly, they tend to consume significant space in commercial facilities. Therefore, known layer-cutters are not always adaptable to existing layouts.
A primary object of the invention is to provide a layer cutter that is safe, effective and efficient in the setting of a home kitchen, or commercial foodservice operation, such as an institutional kitchen or bakery.
Another object of the invention is to provide a layer cutting device that is capable of smooth and quiet operation that does not require a source of electric power.
It is another object of the invention to provide a layer cutting apparatus that is capable of cutting layers into food products that are firm enough to maintain a distinct shape.
It is yet another object of the invention to provide a layer cutting apparatus that is incorporated into the packaging of high volume cakes and capable of one-time use.
These and other objects of the invention are achieved by providing a layer cutting apparatus including a tray having an interior defined by a bottom and sidewall. A sleeve is at least partially disposed in the interior of the tray and a cutting line is attached to the sleeve. The cutting line is configured to be removed from the sleeve by pulling the line outward from one point of the sidewall.
In another aspect of the invention, the invention includes a method of dividing a food product into layers. The method comprises providing a tray containing a food product. The tray has a bottom, a first side, a second side, a front wall, and a back wall. The method also includes the steps of suspending a line between the first side and the second side, adjacent to the front wall and moving the line along the first side and the second side from a position adjacent to the front wall to a position adjacent to the back wall.
In yet another embodiment, the invention includes a food package kit comprising a tray having a bottom. A food product is disposed on the bottom of the tray. A sleeve is at least partially disposed about the perimeter of the food product. A cutting line is attached to the sleeve. At least a portion of the cutting line is located between the sleeve and the food product.
These and other aspects of the invention will be more apparent from the following description of the preferred embodiment thereof when considered in connection with the accompanying drawings and appended claims.
The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which:
While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail.

Top surface 122 extends around notch 120 at fourth wall 108, second wall 106, first wall 104, and third wall 110. In one embodiment, top surface 122 defines a plane substantially parallel to the plane that includes bottom 100, although such configuration is not necessary to the invention.
Tray 14 is preferably fabricated of paperboard or a similar paper product. However, tray 14 may be fabricated of a variety of other food approved materials of sufficient rigidity to at least partially support the weight of a food product. In a preferred embodiment, materials for tray 14 are capable of maintaining their structural integrity during baking temperatures exceeding 350° F. (177° C.). Alternative materials for tray 14 include various metals, glass, or thermoformed plastic material of the type previously described.
Tray 14 may be a variety of sizes sufficient to contain a food product while remaining within the scope of the invention. In one embodiment, the distance between first wall 104 and fourth wall 108 is between about 3 inches and about 30 inches. In another embodiment, the distance between first wall 104 and fourth wall 108 is about 16.75 inches. The distance between second wall 106 and third wall 110 is between about 3 inches and about 35 inches. In another embodiment, the distance between second wall 106 and third wall 110 is about 24.75 inches. Similarly, the height of sidewall 102 from bottom 100 to top surface 122 may also comprise a variety of sizes while remaining within the scope of the invention. In one embodiment, the height of sidewall 102 is between about 1 inch and about 8 inches.
In operation, a food product can be baked in the interior of tray 14. Alternatively, a pre-made food product can be placed on the bottom 100 of tray 14. The food product can be a cake, intermediary food product, or any other baked good. Next, sleeve 12 is placed in tray 14 so that at least a portion of the sleeve 12 is between the food product and the sidewall 106. In a preferred embodiment, sleeve 12 rests on the bottom 100 of tray 14 and extends around the perimeter of the food product, between the food product and the sidewall 102.
In one embodiment, cutting line 40 includes a cotton string. In alternative embodiments, cutting line 40 includes a metal wire, nylon monofilament, polymer-based string, elastomer filament or similar filament capable of withstanding baking temperatures. Cutting line 40 can be fabricated of a variety of other materials having sufficient tensile strength to withstand the force required to separate cutting line 40 from sleeve 12 and move cutting line 40 through a food product 200 during the cutting process. Suitable materials have a tensile strength of at least 1 pound per square inch. Common diameters of cutting line 40 are in the range of about 1 mm to about 0.25 inches.
With reference to
During the cutting operation, cutting line 40 is pulled outward from notch 120. As the force on cutting line 40 overcomes the force attaching cutting line 40 to panel 26, line is pulled away from panel 26 and fourth corner 30 as shown in
As shown in
As cutting line 40 continues to be pulled outward from notch 120, cutting line 40 is pulled away from second side 22 as shown in
An alternative embodiment of the cutting process is shown in
In yet an alternative embodiment, cutting line 40 may be attached directly to the sidewall 102 of tray 14 as shown in
As shown in
Another alternative embodiment of a sleeveless layer cutting apparatus 10 is shown in
When food product 200 rests on bottom 100, food product can be cut into layers by pulling end 41 and end 43 from a location adjacent to first wall 104 to a location adjacent to fourth wall 108. In one embodiment, perforation lines 111 and 113 are substantially parallel to bottom 100. This configuration helps ensure that the lower layer 204 of food product 200 is uniform. Cutting line 40 may be fabricated from a variety of materials described above. Alternatively, cutting line 40 may be comprised of industrial tear tapes. The tear tapes can be incorporated into tray 14 either within the tray or on the surface of the tray. Existing tear tapes are in the range of about 1 mm to about 0.25 inches.
In another embodiment, end 81 of line 80 and end 83 of line 82 can each be fixed to handle 88. As handle 88 is pulled away from first wall 104 toward fourth wall 108, lines 80 and 82 simultaneously pull away from first wall 104, bottom 100, and fourth wall 108 to form separate divisions in the contents of tray 14.
To further partition the food product, additional lines 86, 87, and 89 may be disposed in the tray 14. Line 86 is disposed in second wall 106, bottom 100, and third wall 110. Line 87 is also disposed in second wall 106, bottom 100, and third wall 100. Similarly, line 89 is disposed in second wall 106, bottom 100, and third wall 100. Lines 86, 87, and 89 intersect each of lines 80 and 82. In one embodiment, lines 86, 87, and 89 are parallel to on another. In a preferred embodiment, lines 86, 87, and 89 are each perpendicular to lines 80 and 82.
As discussed above, lines 86, 87, and 89 may be independently pulled from second wall 106 to third wall 110. Alternatively, ends of lines 86, 87, and 89 may be fixed to handle 91. As handle 91 is moved from second wall 106 to third wall 110, lines 86, 87, and 89 simultaneously divide the contents of tray 14.
In one embodiment, handle 88 is attached to first wall 104 using perforation line 93. Similarly, handle 91 is attached to second wall 106 using perforation line 95. When the contents of tray 14 are ready to be partitioned, handle 88 is separated from first wall 104 along perforation line 93. Next, handle 88 is moved toward, and ultimately past fourth wall 108 until lines 80 and 82 are completely separated from the contents of the container. Then, handle 91 can be separated from second wall 106 along perforation 95. Handle 91 is then moved toward and past third wall 110 until lines 86, 87, and 89 are completely separated from the contents of the container.
Although the present invention has been described with reference to preferred embodiments, persons of ordinary skill will recognize that changes can be made in form and detail without departing from the spirit and scope of the present invention.
