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.

First claim

The invention claimed is:

1. A system of stacked food containers comprising:
a first food container comprising a base, the base including:
an upwardly facing food receiving portion to receive a food product, wherein the upwardly facing food receiving portion includes a perimeter and a substantially planar surface; and
at least a portion of a rim is disposed at the perimeter of the upwardly facing food receiving portion, wherein the at least a portion of a rim is raised relatively above the upwardly facing food receiving portion;
wherein the upwardly facing food receiving portion further includes:
a plurality of sector portions, including a first and second sector portion, angularly arrayed with respect to one another, each of the sector portions having an upward facing surface and a plurality of raised projections extending upwardly from the upward facing surface, and the first sector portion having a first sector well and the second sector portion having a second sector well, the second sector well being separate and distinct from the first sector well, wherein the first sector well and the second sector well each extend downwardly from a planar surface of the food receiving portion;
a plurality of channels that delineate respective pairs of the sector portions from one another, each channel of the plurality of channels extending relatively below the upward facing surface of the sector portions; and
a central well about which the sector portions are angularly arrayed, the central well having a perimeter and extending relatively below the upward facing surface of the sector portions, and each channel of the plurality of channels extending to the perimeter of the central well such that each channel is spaced apart from the other channels around the perimeter of the well; and

a second food container comprising a cover, the cover including:
a substantially downward facing interior surface and a substantially upward facing exterior surface, wherein the cover is sized and shaped to provide an interior chamber which protects the food product; and
a central dome portion having a first dome recess sized and shaped to receive at least a portion of the first sector well and a second dome recess sized and shaped to receive at least a portion of the second sector well, wherein the first sector well of the base is engaged with at least a portion of the first dome recess sized and the second sector well of the base is engaged with at least a portion of the second dome recess; and

an air space formed at least in part by the engagement of the first sector well of the base with at least a portion of the first dome recess and the engagement of the second sector well of the base with at least a portion of the second dome recess, wherein the air space is disposed between the base of the first food container and the substantially upward facing exterior surface of the cover of the second food container.

2. The system of stacked food containers of claim 1 wherein the base comprises sugarcane fiber, wood fiber, or bamboo fiber.

3. The system of stacked food containers of claim 1 wherein the cover includes a tab that extends radially outward from the cover.

4. The system of stacked food containers of claim 1 wherein the base is formed from a first single layer of material having a thickness in the range of 0.5 millimeters to 1.0 millimeters and the cover is formed from a second single layer of material having a thickness in the range of 0.5 millimeters to 1.0 millimeters.

5. The system of stacked food containers of claim 4 wherein the first single layer of material has a thickness of 0.8 millimeters and the second single layer of material has a thickness of 0.8 millimeters.

6. The system of stacked food containers of claim 1 wherein the first sector well that may receive liquid drippings from the food product therein.

7. The system of stacked food containers of claim 1 wherein the exterior surface of the cover has a circular raised outer rim spaced radially outward from a center of the cover and a circular raised inner rim spaced radially outward from the center of the cover and spaced radially inward from the raised outer rim.

8. The system of stacked food containers of claim 1 wherein the base includes a plurality of recesses that extend relatively below an adjacent portion of the base, the plurality of recesses positioned radially outward of the upwardly facing food receiving portion.

9. A food container comprising:
a base including:
an upwardly facing food receiving portion, the upwardly facing food receiving portion having an inner surface and a perimeter;
a plurality of radial channels running radially in the inner surface and terminating at a perimeter of a central well such that each radial channel of the plurality of radial channels is spaced apart from the other channels of the plurality of channels around the perimeter of the well; and
a corresponding plurality of sector portions of the upwardly facing food receiving portion delineated by the plurality of radial channels; and

a cover selectively engageable with the base, the cover including a substantially downward facing interior surface and a substantially upward facing exterior surface, the cover sized and shaped to provide an interior chamber to protect the food product, and the cover further having a central dome portion having a first dome recess sized and shaped to receive at least a portion of a first sector well of another base and a second dome recess sized and shaped to receive at least a portion of a second sector well that is separate and distinct from the first sector well of the another base, such that the cover is capable of engaging with another base to form an air pocket.

10. The food container of claim 9 wherein the base includes at least a portion of a raised rim disposed about a perimeter of the upwardly facing food receiving portion, and the interior surface of the cover includes at least a portion of a channel disposed about a perimeter of the cover that is 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.

11. The food container of claim 10 , further comprising:
indicia positioned on or adjacent the rim to aid a user in cutting the food product into pieces along the radial channels.

12. The food container of claim 9 wherein the interior surface of the cover includes at least a portion of a rim disposed about a perimeter of the cover, and
the base includes at least a portion of a channel disposed about a perimeter of the upwardly facing food receiving portion that is sized and dimensioned to engage the at least a portion of the rim of the cover when the cover is engaged with the base.

13. The food container of claim 9 wherein the exterior surface of the cover has a circular raised outer rim spaced radially outward from a center of the cover and a circular raised inner rim spaced radially outward from the center of the cover and spaced radially inward from the raised outer rim.

14. The food container of claim 9 wherein the base includes a plurality of recesses that extend relatively below an adjacent portion of the base, the plurality of recesses positioned radially outward of the upwardly facing food receiving portion.

15. A food container comprising:
a base including:
an upwardly facing food receiving portion, the upwardly facing food receiving portion having an inner surface and a plurality of channels disposed in the inner surface;
a central well having a perimeter disposed about the center of the upwardly facing food receiving portion, wherein each chann
