The tray assembly 10 is illustrated in FIG. 1 being used on grill 14, and it should be understood that the tray assembly 10 can be used for a variety of cooking methods including on a stove top, in a broiler, baked in an oven, or on an indoor grill.

FIG. 2 illustrates a schematic cross-sectional view of one embodiment of the tray assembly 10. Preferably, the tray assembly 10 is a “single-use” tray assembly. By the term “single-use”, it is meant that after normal cooking and preparation of food using the tray assembly 10, the tray assembly 10 is disposed of. The tray assembly 10 can be used as a serving tray or plate to immediately consume the food prepared upon it, but by “single-use” it is meant that the tray assembly 10 would not be cleaned, stored, and brought out for later use to cook and prepare food after already having done so once. To be a single-use tray assembly 10, in general, the tray assembly 10 will be made from inexpensive and easily disposable materials. These materials can include aluminum, plastic, or blends or composites thereof. For example, the tray assembly 10 can be made from aluminum pans, or foil pans, such as pie tins or turkey pans.

In general, the tray assembly 10 includes a first tray. As embodied herein, a first tray 16 is provided and includes a base 18. The base 18 has first and second opposite surfaces 19, 20. The first surface 19 functions as a heating surface 22. That is, normally the heating surface 22 is oriented to be either in direct contact with or above or adjacent to a heat source. The second surface 20 is on an opposite side as the heating surface 22. The second surface 20 is oriented to hold a volume of an aromatic material 24 positioned on the base 18 of the first tray 16.

Preferably, the tray assembly 10 is pre-filled. By the term “pre-filled”, it is meant that the tray assembly 10 already has the aromatic material 24 positioned on the first tray 16 on the base 18 to use the tray assembly 10 for the preparation of food. There is no extra step of orienting the aromatic material 24 in the first tray 16 required, in preferred embodiments.

The aromatic material 24 can be many types of material used for the preparation of food 12. The aromatic material 24 can be wood, wood chips, water, or other material that is heated, smoked, incinerated, or burned to provide a flavoring or product change. Example aromatic materials 24 useable include spices or herbs or mixtures thereof. Other aromatic materials comprise natural or artificial flavorings or mixtures thereof. The material 24 can include solids, liquids, and mixtures thereof.

In the embodiment shown, the first tray 16 further includes a surrounding wall 26. The surrounding wall 26 extends from the base 18 and helps to hold or contain the aromatic material 24 within the base 18. The surrounding wall 26 can be orthogonal relative to the base 18 or can be angled therefrom.

In preferred embodiments, the second tray 28 is non-removably secured to the first tray 16. While it is contemplated that in certain alternative embodiments, the first tray 16 and second tray 28 are separable, preferred arrangements including the “non-removable” security of the second tray 28 and first tray 16. By the term “non-removably secured” and variants thereof, it is meant that the first tray 16 and second tray 28 cannot be separated from each other without bending, breaking, or damaging at least one of the first tray 16 and second tray 28.

In the embodiment illustrated in FIG. 2, the second tray 28 includes a second tray base 30 having first and second opposite surfaces 32, 33. The first surface 32 of the second tray base 30 faces the second surface 20 of the first tray base 18. The second surface 33 of the second tray base 30 defines a cooking surface 36. The cooking surface 36 is for supporting and being in contact with the food 12. The cooking surface 36 is illustrated as flat, but can include ribs, ripples, or other features to help cook the food 30 to create a certain effect.

In general, the cooking surface 36 defines an aperture arrangement to permit the flow of gases from the aromatic material through the cooking surface 36. As embodied herein, the cooking surface 36 defines aperture arrangement 36 in the form of spaced holes 40 that permit the flow of gases from the aromatic material 24 through cooking surface 36 upon the application of heat, such as the application of heat to the heating surface 22 of the first tray 16. The holes 40 can be any type of aperture such as slots, narrow slits, round holes, irregular shaped holes, punctures, etc.

Still in reference to FIG. 2, the second tray 28, in the embodiment shown, includes a wall 42 circumscribing or surrounding the cooking surface 36. In the embodiment shown, the wall 42 is angled relative to the cooking surface 36. The wall 42 can be orthogonal, or, as in the embodiment shown, can be angled obliquely depicted in FIG. 2 as obtusely, relative to the cooking surface 36. By the term “obliquely”, it is meant that the second tray wall 42 is non-orthogonally angled relative to the cooking surface 36, in the embodiment shown.

The tray assembly 10 depicted in FIG. 2 shows the second tray 28 as nested within the first tray 16. By term “nested”, it is meant that the wall 42 of the second tray 28 is circumscribed or surrounded by the surrounding wall 26 of the first tray 16. In the embodiment shown, the wall 42 is against the wall 26.

As mentioned above, in preferred embodiments, the second tray 28 is non-removably connected to the first tray 16. As embodied herein, the second tray wall 42 is non-removably connected to the surrounding wall 26 of the first tray 16. This connection can be through a variety of means. Such means including seaming, tacking, metal fusion bonding, stapling, crimping, etc. In the particular embodiment illustrated, the first tray 16 is connected to the second tray 28 by a crimp connection 44 between the second tray wall 42 and the surrounding wall 26 of the first tray 16.

FIG. 3 illustrates one embodiment of a packaged food product 50 made in accordance with principles of this disclosure. In general, the packaged food product 50 will include the tray assembly 10 as described above. The packaged food product 50 includes the tray assembly 10 with the prepackaged food product 52 oriented on the cooking surface 36 of the second tray 28. The prepackaged food product 52 can include, for example, frozen vegetables, meat, or other proteins, pastas or other types of noodles, and a mixture or blend of any of these. The prepackaged food 52 can be itself contained within packaging, such as a plastic bag, when stored on the cooking surface 36. The packaged food product 50 will include some sort of outer protective, removable and disposable cover, such as wrapper 54. Wrapper 54 is shown enclosing the entire tray assembly 10 with the prepackaged food 52 held within the tray assembly 10. In other embodiments, the outer wrapper 54 may only extend across the top of the second tray 28 such that the surrounding wall 26 of the first tray 16 is exposed. The packaged food product 50 would include the aromatic material 24 already oriented within the volume 56 between the first surface 32 of the second tray base 30 and the second surface 20 of the base 18 of the first tray 16.

To use the packaged food product 50, the consumer would remove the wrapper 54 to expose the prepackaged food 52. If the prepackaged food 52 is also in a wrapper, that wrapper would be removed, and the prepackaged food 52 would be oriented on the cooking surface 36. The tray assembly 10 with the prepackaged food 52 would then be heated, such as placing it on a grill, in an oven, or on a stove top. When the prepackaged food 52 has been cooked to the desired level, the prepackaged food 52 can either be consumed directly from the tray assembly 10 (i.e., the tray assembly 10 is used as a serving tray), or it can be removed from the tray assembly 10 for serving. The entire tray assembly 10 is then discarded after its single use.

In accordance with principles of this disclosure, a method of making a tray assembly is provided. As embodied herein, the method includes placing an aromatic material in a first tray. The aromatic material can be material as described herein including wood, wood chips, water, spices, herbs, natural or artificial flavorings, and any other material that is heated, smoked, incinerated, or burned to provide a flavoring or product change. The first tray can be the type of tray described above, as embodied as tray 16.

Next, there is a step of orienting a second tray over the aromatic material in the first tray. The second tray has a cooking surface defining an aperture arrangement. One useable second tray would be the second tray 28 as described herein.

After the step of placing an aromatic material in the first tray and then orienting a second tray over the aromatic material in the first tray, the method includes a step of securing the second tray to the first tray to ensure that the first tray and second tray are non-separable. The step of securing can include, for example, crimping. In particular, a side wall of the first tray and a side wall of a second tray can be squeezed or crimped together in a way to prevent separation of the two trays.

In accordance with principles of this disclosure, a method of packaging a food product is provided. The method includes a method of making a tray assembly, as described above. In addition, a food product is oriented on the cooking surface 36 of the second tray 28. The food product can be either oriented directly upon the cooking surface, or some sort of packaging or outer wrapper can be placed around the food product and then oriented on the cooking surface 36 of the second tray 28. Next, there is a step of orienting a removable and disposable cover over the food product to trap the food product in the volume defined by the second tray 28. For example, the disposable cover would be oriented to trap the food product against the cooking surface 36. In the example shown in FIG. 3, the outer wrapper 54 is enclosed around the entire tray assembly 10 and packaged food product 50. In other implementations, only a covering would be provided along the top of the tray assembly 10 to trap the packaged food product 50 against the cooking surface 36.

In accordance with principles of this disclosure, a method of flavoring a food product is provided. The method includes placing food, such as food 12, onto the cooking surface 36 of a single-use tray assembly, such as tray assembly 10. The cooking surface defines aperture arrangement 38 therethrough. The tray assembly 10 includes base arrangement 18 under the cooking surface 36 and aromatic material 24 within the base arrangement 18. Next, the tray assembly 10 is heated to heat the aromatic material 24 and cause the aromatic material 24 to give off gas, fumes, steam, a mist, or a combination of these. Next, the gas, fumes, steam, mist, or combinations thereof are allowed to flow through the aperture arrangement 38 in the cooking surface 36 to the food product 12 on the cooking surface 36. The food product 12 can then be removed from the cooking surface 36, and the single-use tray assembly 10 is discarded.

The above description represents examples. Many embodiments can be made.
