References to or may be construed as inclusive so that any terms described using or may indicate any of a single, more than one, and all of the described terms. As used herein, the term freshness refers to a food item retaining a consistency, texture, and/or taste, similar to the consistency, texture and/or taste of a food item at the time it is made, by limiting the amount of liquid that is reabsorbed into the prepared food once placed in a container or display.

[0030] Referring initially to FIGS. 1-6, a first exemplary embodiment of a food freshness device 10 is illustrated. Food freshness device 10 includes a base 24 having a support surface 28 and a plurality of drainage cells 20 bounded by sidewalls 18, and legs 26 extending from select sidewalls 18 to form flow channels 22. Flow channels 22 are designed to reduce pooling under the food item 29 by directing liquid flow away from the food item 29, thereby reducing the likelihood of reabsorption of liquid into the food item 29.

[0031] Referring now to FIGS. 5 and 6, the base 24 includes a support surface 28 disposed in a first plane 11, and a second plane 12 substantially parallel to the first plane 11. The support surface 28 is constructed and arranged to support the food item 29 thereon, and may be substantially flat in order to support the food item 29 without displacing toppings, for example sauces or other items. Extending between the support surface 28 and second plane 12 are sidewalls 18 (FIG. 2). The sidewalls 18 are constructed and arranged to form drainage cells 20. As best shown in FIGS. 1 and 2, the sidewalls 18 are arranged such that they circumscribe and define openings 21 of drainage cells 20 within base 24. The depth of the drainage cells 20 is defined by the length of the sidewall 18. The drainage cells 20 are arranged in an open construction that join together to form an array of drainage cells 20, such that a grid, mesh, lattice, or grate design is formed. The drainage cells 20 may be aligned in horizontal rows and vertical columns as shown in FIGS. 1 and 2, or may be offset as described in greater detail below. While the present embodiment shows drainage cells 20 as square shaped, it is understood by one of skill in the art that the drainage cells 20 can have any desired shape, including but not limited to square, rectangle, hexagonal, diamond, oblong, or any polygon or the like, depending on the arrangement of the sidewalls 18.

[0032] Referring now to FIGS. 3-6, food freshness device 10 also includes a plurality of legs 26 constructed and arranged to create flow channels 22 between substrate 30 (FIG. 6) and base 24. In the present embodiment, the legs 26 are formed by extending the length of a select number of sidewalls 18. As illustrated, length L1, of the sidewalls 18a is determined by the distance between the first plane 11 and the second plane 12. The length of the sidewalls 18a thus corresponds to the distance between the first plane 11 and second plane 12. However, a number of the sidewalls 18b include legs 26 extending beyond the second plane 12. The length (L2) of the legs 26 therefore corresponds to the distance between the second plane 12 and the substrate 30. The length (L2) of the legs 26, is sized to elevate the food item 29 from the substrate and to allow space for liquid to flow away from the food item through channels 22. As will be appreciated, the depth of each channel 22 is defined by the length of the legs 26 that define the channel 22. The distance between the food item resting on the surface 28 and the substrate 30 is determined by the length of the tallest legs 26, L2. As also illustrated, the sidewalls 18 and the legs 26 may be made from a singular piece of material, such that the sidewalls 18 and the legs 26 are a unitary construction, or they may be two or more separate components that are joined together, as would be known to one of skill in the art.

[0033] As best shown in FIGS. 5 and 6, the legs 26 extend beyond the second plane, and form flow channels 22. The base 24 is positioned such that at least some of the legs 26 contact the substrate 30 when the food item 29 is placed on the support surface 28. Because sidewalls 18a are elevated a distance from the substrate, flow channels 22 are created under and along the base 24, by legs 26. The base is preferably sufficiently rigid so that it does not collapse when heavier items such as such as calzones, nachos, or chicken wings are placed on the food freshness device 10, thereby maintaining the integrity of the flow channels 22, to allow for the flow of liquid and steam as described above. The base may also be sufficiently flexible to allow for insertion into any container, including containers with smaller, or irregularly sized openings. The material may be chosen in light of the food item the base is intended to support. A more rigid material may be used for heavier items, such multi topping pizza, and a less rigid material may be used for lighter food items such as baked goods. As is understood by one of skill in the art, a variety of lengths for legs 26 may be utilized, depending on the type of food item, its weight, and the anticipated amount of liquid and/or steam that will be released.

[0034] Referring now to FIGS. 7-10, a second exemplary embodiment is illustrated where the drainage cells 20 can be arranged in a variety of patterns. In this exemplary embodiment, the same or similar elements of the embodiment of FIGS. 1-6 are labeled with the same reference numbers preceded by the numeral 1. This embodiment has the same elements as the previous embodiment, except the drainage cells 120 are arranged in an offset, staggered arrangement. In this manner, a pattern of cells having horizontal rows of drainage cells 120 that are offset from adjacent rows of drainage cells 120, so that the drainage cells 120 are not aligned in vertical rows. As with the previous embodiment, the drainage cells 120 can be square, rectangle, hexagonal, diamond, oblong, polygon or the like, depending on the arrangement of the sidewalls 118, and arranged in any offset configuration, as may be desired. Such an arrangement may be desirable depending upon the intended use of the base 124, for example the shape of the container may determine if an offset arrangement of cells 120 is desired, whether the cells be offset vertically or horizontally.

[0035] Referring now to another exemplary embodiment, as best shown by FIG. 11, the legs 226 may have different lengths within a single base 224. In this embodiment, the same or similar elements of the embodiment of FIG. 1 are labeled with the same reference numbers preceded with the numeral 2. As shown in FIG. 11, legs 226a, 226b and 226c all have varying lengths. As illustrated in the present embodiment, the longest legs 226a, having a length L4, are positioned toward the center of the food item, while the shortest legs 226c, having a length L2 are positioned at the periphery of the food item. Legs 226b, having an intermediate length L3, are positioned in a region between legs 226a and 226c. This arrangement is advantageous for food items with a large surface area, such as pizza, in which directing steam and grease away from the center of the food item may be desirable for preserving freshness. Likewise, and by way of example only, it may be advantageous to direct the flow of liquid and steam in other directions, such as toward the center of the food item, in order to preserve freshness. For example, foods with a hole in the middle, such as donuts or bundt cake, may benefit from legs 226 of length L4 at the periphery of the food item and legs 226 of length L2 in the middle of the food item, thereby directing liquid and steam to flow toward the center of the food item.

[0036] By varying the length of the legs 226, the flow of the liquid into the area beneath the food item can be selectively directed. For instance, as shown in FIG. 11, the liquid can be directed away from the center of the base 224. The legs 226 can be arranged in any array of legs with similar lengths, selectively positioned in order to achieve the desired flow of liquid into the flow channels 222. For example, the flow could be directed from the center of the food item to the outer edges, from the front to the back, or from the outer edges to the center. In this embodiment, depending on the weight of the food item, some legs 226 may not contact the substrate 30 unless the food item is heavy enough to press the legs 226 down to contact the substrate 30.

[0037] During use, the food freshness device 10 is placed on a substrate and a hot food item 29 is removed from the oven, or taken off the stove, and placed on the support surface 28. The base 24 elevates the food item 29 above the substrate by the legs 26. The flow channels 22 allow the liquid and steam to flow away from the food item 29 and through the flow channels 22 under base 24. The flow channels 22 operate to reduce pooling in the drainage cells 20 that can result from liquid filling the cells. The channels allow liquid to flow along the length of the base 24 so as not to pool in any one area under the food item.

[0038] Returning now to FIG. 12, alternatively, as would be understood by one of skill in the art, the device can inverted for use, such that the surface 328 is arranged to contact a substrate 330, such as a container or a shelf. In this embodiment, the same or similar elements of the embodiment of FIG. 6 are labeled with the same reference numbers preceded with the numeral 3. In this configuration, the second plane 312 is positioned above the first plane 311, and the legs 326 extend upward to support the food items. In this embodiment the flow channels 322 are arranged above the drainage cells 320 such that when a cell 320 fills with liquid, the liquid has room to overflow into the next cell, preventing the liquid from touching the bottom of the food item 329. The legs 326 can be arranged in a variety of lengths as to lift the food item off of the substrate by varying lengths. As described herein, by varying the length of the legs, the flow of the liquid can be directed away from the food item as desired. For instance, if legs 326 of the longest length are arranged toward the center of the food item 329, the liquid can be directed away from the center of the food item, and toward the periphery of the food item 329. Alternatively, the legs 326 can be arranged such that the longest legs 326 are in the front of the food item, and the lowest legs 326 are in the back, thereby directing the flow of liquid and steam toward the back of the box, display, or container. As is understood by one of skill in the art, the legs 326 can be arranged in any array in order to direct the flow if liquid and steam as desired.

[0039] In all of the foregoing embodiments, substrate 30 may include any type of container or display, as would be known to one of skill in the art, such as for example, pizza boxes, take-out containers, bakery shelves, bakery racks, or the like. The substrate 30 may be absorbent or non-absorbent depending on the desired packaging and use.

[0040] In addition, the food freshness device 10 of any of the foregoing embodiments may be made from a variety of materials including those that are compostable and/or recyclable, such as the material disclosed in U.S. Application No. 20170144813 A1, crystalline polylactic acid, polybutylene succinate, and compostable polyethylene terephthalate. The present embodiments may be made of crystalline polylactic acid, which is both microwavable, compostable, and biodegradable. Other materials that are microwavable and/or recyclable, biodegradable or compostable may also be utilized, as would be known to those of skill in the art. While materials that are microwavable, compostable, and/or biodegradable are desirable, any variety of material can be utilized provided that it can be formed into the desired shape, and will preferably support the weight of food items up to about 2-4 pounds.

[0041] After the food freshness device 10 of any of the foregoing embodiments is manufactured, it can be cut into the desired size for the container or display. The freshness device 10 can be made of any of variety of materials, as described above, and can be made in a variety of colors. It may also be colorless or colored to match packaging or to match a display case or shelving, so that it is not noticed in a store display.

[0042] It will be understood by those skilled in the art that various changes in the form and details may be made herein without departing from the spirit and scope of the invention as defined by the appended claims. For example, the materials disclosed herein may be readily changed, as may the dimensions and geometric configurations of the components described herein, i.e. the cells may be a variety of shapes and sizes, the length of the legs may vary, the base may be made of a variety of materials, the cells may be configured in a variety of patterns, and the channels may flow in a variety of directions. Also elements that are shown in combination may be shown in different combinations or may be eliminated. Thus, the details of these components as set forth in the above-described examples, should not limit the scope of the claims.

[0043] Further, the purpose of the Abstract is to enable the U. S. Patent and Trademark Office, and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the claims of the application nor is intended to be limiting on the claims in any way.
