Abstract

Systems and methods for providing compostable food containers which preserve the quality of a food product for an extended duration of time, and which optionally allow for cooking of the food product therein. In some implementations, the food containers are sturdy, stackable, insulating, and require minimal or no manual labor to assemble. In some implementations, the food container includes a base and a cover which cooperate to form a closed chamber for supporting, protecting, insulating and optionally cooking a food product, such as a pizza. The base and cover may each be formed of a single layer of material including, but not limited to, molded sugarcane fiber (“bagasse”), molded wood fiber, molded bamboo fiber, molded paper or plastic. The base and/or the cover may include one or more detachable portions that may be selectively separable from the remaining portion of the base and/or cover.

First claim

The invention claimed is:

1. A food container comprising:
a base having at least one edge, the base comprising a raised rim disposed about a perimeter of an upwardly facing food receiving portion which receives a food product, the food receiving portion comprising a substantially planar surface and a plurality of channels each being recessed downwardly into the planar surface and extending across at least a portion of the planar surface, with at least one channel and a corresponding portion of the at least one edge delineating a respective detachable portion of the food receiving portion, each of the detachable portions selectively separable from other detachable portions; and
a cover selectively engageable with at least a portion of the raised rim of the base, the cover comprising a substantially downward facing interior surface and a substantially upward facing exterior surface, the interior surface having a perimeter channel sized and dimensioned to engage the at least a portion of the raised rim of the base when the cover is engaged with the base, and the cover sized and shaped to provide an interior chamber which protects the food product, the interior chamber defined at least in part by the interior surface of the cover and a corresponding part of the food receiving portion.

2. The food container of claim 1 wherein the at least one detachable portion is selectively separable along a separation line formed into the base along the at least one channel.

3. The food container of claim 2 wherein the at least one edge includes a notch directed inwards towards the raised rim, the notch aligned with the separation line.

4. The food container of claim 2 wherein a subset of the channels have separation lines.

5. The food container of claim 2 wherein the base comprises a material that has a uniform thickness except at the separation lines, the separation lines which comprise a portion of the base that has a reduced thickness relative to other portions of the base.

6. The food container of claim 2 wherein the separation line comprises a line of a plurality of perforations.

7. The food container of claim 2 wherein the separation line comprises a line that has been weakened before distribution of the food container by the manufacture thereof.

8. The food container of claim 2 further comprising:
a flange that extends outwardly the raised rim of the base.

9. The food container of claim 2 further comprising:
a flange that extends outwardly from the food receiving portion, the flange having a first pair of parallel sides and a second set of parallel sides that form an exterior periphery for the food container, wherein the first pair and the second pair of parallel sides surrounds the raised rim.

10. The food container of claim 9 , wherein the flange includes at least one notch located along one of the sides of the flange, the at least one notch directed inwards towards the raised rim and aligned with the separation line.

11. The food container of claim 10 , wherein the at least one notch is manipulable to effect a separation along the separation line.

12. The food container of claim 1 wherein the base comprises a number N of sector portions, the cover comprises the number N of interior chambers, and each of the interior chambers is vertically aligned with one of the detachable portions when the cover is engaged with the base.

13. The food container of claim 1 wherein the cover includes a plurality of detachable cover portions, each of the cover detachable portions corresponding to a detachable portion on the base, and at least one of the cover detachable portions is selectively detachable from at least one other cover detachable portions.

14. The food container of claim 1 wherein the base comprises a number N of sector portions, the cover comprises a number M of interior chambers, and wherein N is a positive integer and M is a positive integer that is less than N.

15. The food container of claim 1 wherein the base is rectangular in shape with a length and a width and each of the channels extends across at least a portion of the width of the base.

16. The food container of claim 1 wherein each detachable portion includes a raised detachable portion rim which extends upward from the planar surface and is adjacent at least one of the channels which delineate the detachable portion.

17. The food container of claim 1 wherein the base has a rectangular-shaped outer perimeter with rounded corners, the outer perimeter defined by first and second parallel edges and third and fourth parallel edges, and each of the channels are non-parallel with each of the first, second, third, and fourth edges.

18. The food container of claim 1 wherein the base comprises a base flange surrounding at least a portion of the raised rim, and the cover comprises a cover flange surrounding at least a portion of the perimeter channel of the interior surface.

19. The food container of claim 18 wherein the base flange comprises at least one base fastening recess which extends downwardly from the base flange, and the cover flange comprises at least one corresponding cover fastening protrusion which extends downwardly from the cover flange, the at least one base fastening recess sized and dimensioned to receive at least a portion of the at least one cover fastening protrusion when the cover is engaged with the base.

20. The food container of claim 19 wherein the at least one base fastening recess and the at least one cover fastening protrusion are each sized and dimensioned to provide an audible cue when the at least one base fastening recess is separated from the cover fastening protrusion.

21. The food container of claim 19 wherein the at least one base fastening recess has a depth that is greater than 5 millimeters and a diameter that is greater than 8 millimeters, and the at least one cover fastening protrusion has a depth which is 1 millimeter less than the depth of the at least one base fastening recess, and a diameter which is 1 millimeter greater than the diameter of the at least one base fastening recess.

22. The food container of claim 18 wherein the base flange comprises at least one base fastening protrusion which extends upwardly from the base flange, and the cover flange comprises at least one corresponding cover fastening recess which extends upwardly from the cover flange, the at least one cover fastening recess sized and dimensioned to receive at least a portion of the at least one base fastening protrusion when the cover is engaged with the base.

23. The food container of claim 1 wherein each detachable portion comprises a sector well that extends downwardly from the planar surface.

24. The food container of claim 23 wherein the sector well of each detachable portion has a rim adjacent the planar surface, the rim having a profile in the shape of at least one of an oval, a circle, a triangle, a square, or a symbol.

25. The food container of claim 24 wherein each of a plurality of features comprising the raised rim, the sector wells, the channels, and the raised sector ribs is spaced apart from at least one other of the plurality of features by a distance which is less than or equal to one inch.

26. The food container of claim 1 wherein each detachable portion comprises a plurality of raised sector ribs extending upwardly from the planar surface.

27. The food container of claim 1 wherein the base
