2. The container of claim 1 , wherein a top surface of each of the plurality of reinforcing ribs corresponds with the first curved portion and the second curved portion.

3. The container of claim 1 , wherein the first radius of curvature is greater than the second radius of curvature.

4. The container of claim 1 , further comprising a label inseparably coupled to the plurality of sidewalls using an in-mold labeling process.

5. The container of claim 1 , wherein the plurality of sidewalls form a substantially rectangular perimeter.

6. The container of claim 1 , wherein an intersection of the second curved portion and the plurality of sidewalls is substantially perpendicular.

7. The container of claim 1 , wherein the central region comprises:

an inner portion; and

an inner surrounding portion extending entirely around the inner portion and disposed on a first plane; and

wherein the outer surrounding portion extends entirely around the inner surrounding portion and is disposed on a second plane, the second plane vertically separated from the first plane.

8. The container of claim 7 , wherein an upper portion of the second curved portion is disposed on a third plane, the third plane substantially perpendicular to the plurality of sidewalls and vertically separated from the first plane and the second plane.

9. A container comprising:

a plurality of sidewalls extending in a substantially vertical direction, the plurality of sidewalls terminating at a bottom plane;

a bottom wall comprising:

a substantially flat region; and

a sloped region comprising a first curved portion defining an upward slope and a second curved portion defining a downward slope, the second curved portion merging with the plurality of sidewalls such that an intersection of the second curved portion and the plurality of sidewalls is substantially perpendicular; and

a plurality of reinforcing ribs disposed beneath the sloped region, one of the plurality of reinforcing ribs having a bottom surface that is substantially coplanar with an outer surrounding portion of the substantially flat region and separated from the bottom plane.

10. The container of claim 9 , wherein a top surface of each of the plurality of reinforcing ribs coincides with the sloped region.

11. The container of claim 9 , wherein a radius of curvature of the first curved portion is greater than a radius of curvature of the second curved portion.

12. The container of claim 9 , further comprising a label inseparably coupled to the plurality of sidewalls using an in-mold labeling process.

13. The container of claim 9 , wherein the substantially flat region comprises:

an inner portion; and

an inner surrounding portion extending entirely around the inner portion and disposed on a first plane; and

wherein the outer surrounding portion extends entirely around the inner surrounding portion and is disposed on a second plane, the second plane vertically separated from the first plane.

14. The container of claim 13 , wherein the second curved portion includes an upper portion proximate the intersection of the second curved portion and the plurality of sidewalls, the upper portion disposed on a third plane, the third plane substantially perpendicular to the plurality of sidewalls and vertically separated from the first plane and the second plane.

15. A container comprising:

a sidewall extending in a substantially vertical direction, the sidewall terminating at a bottom plane;

a bottom wall comprising:

a first curved portion having a first radius of curvature with a first center of curvature located on a first side of the bottom wall; and

a second curved portion terminating at the sidewall, the second curved portion having a second radius of curvature with a second center of curvature located on a second side of the bottom wall opposite the first side; and

a reinforcing rib located on the second side of the bottom wall, the reinforcing rib having a bottom surface that is substantially coplanar with an outer surrounding portion of the bottom wall and separated from the bottom plane;

wherein the first radius of curvature is greater than the second radius of curvature.

16. The container of claim 15 , wherein the bottom wall further comprises:

an inner portion; and

an inner surrounding portion extending entirely around the inner portion and disposed on a first plane; and

wherein the outer surrounding portion extends entirely around the inner surrounding portion and is disposed on a second plane, the second plane vertically separated from the first plane.

17. The container of claim 16 , wherein an upper portion of the second curved portion is disposed on a third plane, the third plane substantially perpendicular to the sidewall and vertically separated from the first plane and the second plane.

18. The container of claim 15 , wherein the sidewall forms a substantially circular perimeter.

19. The container of claim 15 , wherein a top surface of the reinforcing rib intersects a bottom portion of the first curved portion and the second curved portion.
