Abstract

Foldable container including a base having a first base portion and an opposing second base portion. The base has a base surface free of hinge lines between the first base portion and the second base portion. A sidewall surrounds at least a portion of the base and extends generally upward from the base with a non-uniform height to define a compartment. A rim having a first rim portion and an opposing second rim portion is disposed proximate the top edge of the sidewall. At least one transition region is formed in the sidewall to allow the first base portion to pivot between an open position and a closed position. When in the open position, the container defines a plate. When in the closed position, the first base portion defines at least a portion of a cover relative to the second base portion. A packaged product is also provided, including a foldable container and a cover member removably attached to the rim of the foldable container in the open position to contain a product therein.

Claims (24)

1. A foldable container comprising:

a base including a first base portion and an opposing second base portion, the base having a base surface free of hinge lines between the first base portion and the second base portion;

a sidewall surrounding at least a potion of the base and extending generally upwardly a distance to define a non-uniform sidewall height, the sidewall having an inner reference surface and a top edge; and

a rim surrounding the base to define a compartment therein, the rim having a first rim portion corresponding with the first base portion and an opposing second rim portion corresponding with the second base portion;

the sidewall having at least one transition region formed therein to allow the first base portion to pivot between an open position and a closed position, the first base portion defining at least a portion of a cover relative to the second base portion when in the closed position.

2. The foldable container of claim 1 , wherein the sidewall has a continuously varying height.

3. The foldable container of claim 1 , further comprising an intermediate portion surrounding the base, the intermediate portion disposed adjacent the base.

4. The foldable container of claim 3 , wherein the first rim portion includes a segment disposed proximate a top edge of the intermediate portion.

5. The foldable container of claim 3 , wherein the second rim portion is disposed proximate a top edge of the sidewall.

6. The foldable container of claim 1 , wherein the transition region has a contoured surface when the first base portion is in the open position.

7. The foldable container of claim 6 , wherein the contoured surface of the transition region is convex relative to the inner reference surface of the sidewall.

8. The foldable container of claim 1 , wherein the transition region defines a boundary edge with the inner reference surface of the sidewall.

9. The foldable container of claim 8 , wherein the boundary edge includes a line of weakness.

10. The foldable container of claim 1 , wherein the transition region includes a variation in a property of the sidewall, the variation in property including at least one of a variation in material, thickness, or strength.

11. The foldable container of claim 1 , wherein a portion of the base between the first base portion and the second base portion has a generally arcuate configuration when the first base portion is in the closed position.

12. The foldable container of claim 1 , further comprising a hinge defined between the first rim portion and the second rim portion.

13. The foldable container of claim 12 , wherein the hinge includes a groove formed in the rim.

14. The foldable container of claim 1 , further comprising a fastener disposed proximate at least one of the first rim portion or the second rim portion to maintain the first base portion in the closed position.

15. The foldable container of claim 1 , wherein the first rim portion and the second rim portion form a substantially leak-resistant seal therebetween when the first base portion is in the closed position.

16. The foldable container of claim 1 , wherein the base is oriented at an angle with respect to the rim, when in the open position.

17. The foldable container of claim 1 , wherein the rim includes at least one venting feature.

18. The foldable container of claim 17 , wherein the venting feature is a recess or slot.

19. The foldable container of claim 1 , wherein the base includes at least one product centering feature.

20. The foldable container of claim 1 , further comprising a cover member removably attached to the rim.
