TRAY
A tray includes a plurality of elongated pockets, such as for receiving raw bread dough therein. In one embodiment, the pockets are defined by a lower wall and adjacent side walls, and the lower walls and side walls are spaced away from a base wall of the tray.
This application claims priority to U.S. Provisional Application Ser. No. 60/867,051, filed Nov. 21, 2006.
BACKGROUND OF THE INVENTIONThe present invention relates generally to a tray, which can be used for transporting and storing items, including food items such as raw bread dough.
Currently, some restaurants featuring freshly-baked bread ship frozen raw bread dough from central locations to each of the stores in disposable cardboard trays. In the store, the trays of frozen bread dough are placed on metal sheets that are supported in a large rack where the dough is thawed and allowed to rise. The risen dough is then removed from the trays and placed in ovens for baking. The cardboard trays cannot be reused and are therefore discarded, which is costly and environmentally undesirable.
SUMMARY OF THE INVENTIONA molded plastic tray includes a plurality of elongated pockets, such as for receiving raw bread dough therein.
In one embodiment, the pockets are defined by a lower wall and adjacent side walls, and the lower walls and side walls are spaced away from a base wall of the tray. The tray may be rotomolded or twin sheet thermoformed. The rotomolding process creates a tray that is free of hard edges, crevices or corners, which makes the tray easy to clean and reuse for food items. Alternatively, the tray could be twin sheet thermoformed.
In another embodiment, the pockets and dividers are molded in a single thermoformed sheet.
In use, the raw bread dough is shipped to the stores in the trays. At the stores, the trays support themselves in a rack for thawing and rising, or can alternatively be placed on the metal sheets currently used. After rising, the raw dough is removed from the trays and baked. The empty trays are then returned to the central location where they are washed and reused.

As shown in
The tray 10 of the embodiment illustrated is made by rotomolding a polymer, such as polypropylene or polyethylene or other suitable materials in a suitable rotomold. The rotomolding process creates a tray 10 that is free of hard edges, crevices or corners, which makes the tray 10 easy to clean and reuse for food items. Alternatively, the tray 10 could be twin sheet thermoformed.
In use, the raw bread dough is shipped to the stores in the trays 10. At the stores, the trays 10 support themselves in a rack for thawing and rising, or can alternatively be placed on the metal sheets currently used. After rising, the raw dough is removed from the trays 10 and baked. The empty trays 10 are then returned to the central location where they are washed and reused.
A tray 110 according to another embodiment of the present invention is shown in
Referring to
In use, the raw bread dough is shipped to the stores in the trays 110. At the stores, the trays 110 support themselves in a rack for thawing and rising, or can alternatively be placed on the metal sheets currently used. After rising, the raw dough is removed from the trays 110 and baked. The empty trays 110 are then returned to the central location where they are washed and reused.
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
Claims
1. A molded plastic tray comprising:
- a base; and
- a plurality of elongated, parallel pockets defined above the base.
2. The tray of claim 1 further including a pair of longitudinal walls and a plurality of dividers extending transversely between the longitudinal walls to define the pockets.
3. The tray of claim 2 wherein the dividers each include a pair of spaced-apart side walls each partially defining an adjacent one of the plurality of pockets.
4. The tray of claim 3 wherein the base includes a base wall and wherein each of the plurality of pockets includes a lower wall spaced upwardly from the base wall.
5. The tray of claim 4 wherein the side walls are spaced upwardly from the base wall.
6. The tray of claim 2 wherein the base includes a base wall and wherein each of the plurality of pockets includes a lower wall spaced upwardly from the base wall.
7. The tray of claim 6 wherein the base wall includes a plurality of elongated recesses generally aligned with the dividers, such that dividers of a similar tray stacked below would be received in the recesses.
8. The tray of claim 1 further including a lip protruding from a periphery of the tray.
9. The tray of claim 1 wherein the tray is rotomolded.
10. A thermoformed tray having a plurality of elongated, parallel pockets defined therein.
11. The tray of claim 9 wherein each of the plurality of pockets includes a lower wall, a pair of spaced apart side walls and a pair of spaced apart end walls.
12. The tray of claim 11 further including a plurality of dividers, each between a pair of adjacent ones of the plurality of pockets, each divider including a pair of the plurality of side walls.
13. The tray of claim 12 wherein each of the dividers further includes an upper wall connecting upper edges of the pair of side walls.
14. The tray of claim 13 further including a lip protruding from a periphery of the tray.
15. A molded plastic tray comprising:
- a base wall;
- a plurality of elongated, parallel pockets each having a lower wall spaced above the base wall;
- a pair of longitudinal walls, the pockets between the longitudinal walls; and
- a plurality of dividers extending transversely between the longitudinal walls, each of the dividers including a pair of spaced-apart side walls, the plurality of pockets defined between side walls of the plurality of dividers.
16. The tray of claim 15 wherein the base wall includes a plurality of elongated recesses generally aligned with the dividers, such that dividers of a similar tray stacked below would be received in the recesses.
17. The tray of claim 16 further including a lip protruding from a periphery of the tray.
18. The tray of claim 17 wherein the tray is rotomolded.
19. The tray of claim 15 wherein the tray is rotomolded.
