A lower receptacle section with a flat base and upwardly sloping side walls mates with an upper cover section a flat top and downwardly sloping side walls. A hinge connects portion of the lower section lip to a portion of the upper cover section lip. Integrally formed v-shaped ribs in the flat base and the flat top provide structural strength, and pre-formed creases (or fold lines) facilitate folding of the food box for disposal.

1. A foldable insulated food box comprising:a lower receptacle section having a flat base and side walls sloping outwardly from the perimeter of the flat base to a lower section lip;an upper cover section having a flat top and side walls sloping outwardly from the perimeter of the flat top to an upper section lip;a hinge connecting a portion of the lower section lip to a portion of the upper section lip so that the upper cover section pivots between a closed position wherein the upper cover section cooperates with the lower receptacle section to form a closed container and an open position wherein the upper cover section folds away from the lower section along the hinge to permit access to the contents of the lower receptacle section;at least one diagonal v-shaped rib in the flat base; andat least one diagonal v-shaped rib in the flat top, wherein the flat base diagonal v-shaped rib is generally aligned with the flat top diagonal v-shaped rib, so that, when the upper cover section is in the closed position the upper cover section and the lower receptacle section can be folded simultaneously along the generally aligned v-shaped ribs to create a relatively smaller configuration for disposal.2. The device of claim 1, further comprising:a second diagonal v-shaped rib in the flat top.3. The device of claim 2, further comprising:a second diagonal v-shaped rib in the flat base.4. The device of claim 1, further comprising:a fastener attached to a lower receptacle section side wall for retaining the folded food box in the relatively smaller configuration for disposal.5. The device of claim 1, wherein the flat bottom of the lower receptacle section is rectangular and cooperates with the lower receptacle section sloping side walls to form a generally rectangular lower receptacle section having four lower receptacle section corners, wherein the flat top of the upper cover section is rectangular and cooperates with the upper cover section sloping side walls to form a generally rectangular upper cover section having four upper cover section corners, and wherein the generally rectangular upper cover section cooperates with the generally rectangular lower receptacle section to form a generally rectangular foldable disposable food box with mating lower section sloping side walls and upper section sloping side walls.6. The device of claim 5, further comprising:a gusset in each corner of the generally rectangular lower receptacle section; anda gusset in each corner of the generally rectangular upper cover section.7. The device of claim 1, wherein the flat bottom in the lower receptacle section is generally circular and the flat top in the upper receptacle section is generally circular, so that the lower receptacle section and the upper receptacle section cooperate to form a generally circular food box.8. The device of claim 1, wherein the lower receptacle section, the upper cover section, and the hinge are formed from a single sheet of expanded foam.9. The device of claim 1, wherein the hinge further comprises adhesive material commonly attached to a portion of the lower receptacle section and a portion of the upper cover section.10. The device of claim 1, wherein the upper cover section includes at least one tab opposite the hinge, the lower receptacle section includes at least on tab receiver opposite the hinge, and the tab is received in the tab receiver when the upper cover section is aligned with the lower receptacle section in the closed position.11. The device of claim 5, wherein the lower receptacle section includes a pre-formed crease along each side of the generally rectangular flat bottom and the upper cover section includes a pre-formed crease along each side of the generally rectangular top, so that a downward force applied to each corner of the closed food box results in a flattening of the upper cover section and a flattening of the lower receptacle section for compact disposal of the closed food box.12. The device of claim 3, wherein the upper cover section includes at least one tab opposite the hinge, the lower receptacle section includes at least on tab receiver opposite the hinge, and the tab is received in the tab receiver when the upper cover section is aligned with the lower receptacle section in the closed position.13. The device of claim 8, wherein the upper cover section includes at least one tab opposite the hinge, the lower receptacle section includes at least on tab receiver opposite the hinge, and the tab is received in the tab receiver when the upper cover section is aligned with the lower receptacle section in the closed position.14. The device of claim 9, wherein the upper cover section includes at least one tab opposite the hinge, the lower receptacle section includes at least on tab receiver opposite the hinge, and the tab is received in the tab receiver when the upper cover section is aligned with the lower receptacle section in the closed position.
