A container having at least one wall moveable between an upright position and a collapsed position on the floor. A hinge connecting the wall to the base includes a first axis and a second axis offset from the first axis. The hinge is locked when the wall is in the upright position to prevent rotation about the second axis but permit rotation about the first axis.

What is claimed is: 1. A container comprising: a base; a wall movable between an upright position and a collapsed position; a hinge connecting the wall to the base, the hinge including a first axis and a second axis offset from the first axis, the hinge locked when the wall is in the upright position to prevent rotation about the second axis but permit inward rotation of the wall about the first axis, and unlocked when the wall is not in the upright position to permit inward rotation of the wall about the second axis. 2. The container of claim 1 wherein the hinge permits rotation about the first axis and the second axis when the wall is not in the upright position. 3. The container of claim 1 wherein the hinge becomes unlocked based upon rotation of the wall from the upright position to a first position between the upright position and the collapsed position. 4. The container of claim 1 wherein the wall is generally parallel to the base when the wall is in the collapsed position. 5. The container of claim 1 further including a lower wall portion extending upward from the base, the wall connected by the hinge to the lower wall portion of the base. 6. The container of claim 1 wherein the hinge includes a hinge member pivotably connected to the base about the first axis and pivotably connected to the wall about the second axis. 7. The container of claim 6 wherein the wall is locked against rotation relative to the hinge member when the wall is in the upright position. 8. The container of claim 7 wherein the wall is locked against rotation relative to the hinge member when the wall is in any position between the upright position and a first position, the first position between the upright position and the collapsed position. 9. The container of claim 6 further including a first interlocking feature on the wall that prevents rotation about the second axis but permit rotation about the first axis when the wall is in the upright position. 10. The container of claim 9 further including a second interlocking feature on the base that is complementary to the first interlocking feature. 11. The container of claim 10 wherein at least one of the first interlocking feature and the second interlocking feature includes an arcuate surface. 12. The container of claim 11 wherein the arcuate surface has a center point not aligned with the second axis. 13. The container of claim 12 wherein the center point is substantially aligned with the first axis. 14. The container of claim 1 wherein the base includes an integral lower wall portion extending upwardly therefrom, the wall having a lower edge contacting an upper edge of the lower wall portion to prevent the inward rotation of the wall about the second axis. 15. The container of claim claim 1 wherein a lower edge of the wall includes an arcuate surface interlocking with an arcuate surface on the base to prevent the inward rotation of the wall about the second axis when the wall is in the upright position. 16. A container comprising: a base; a wall movable between an upright position and a collapsed position; a hinge connecting the wall to the base, the hinge including a hinge member pivotably connected to the base about a first axis and pivotably connected to the wall about a second axis offset from the first axis, the hinge locked when the wall is in the upright position to prevent rotation about the second axis but permit rotation about the first axis, and unlocked when the wall is not in the upright position to permit rotation about the second axis; a first interlocking feature on the wall that prevents rotation about the second axis but permits rotation about the first axis when the wall is in the upright position; and a second interlocking feature on the base that is complementary to the first interlocking feature, at least one of the first interlocking feature and the second interlocking feature including an arcuate surface. 17. The container of claim 16 wherein the arcuate surface has a center point not aligned with the second axis. 18. The container of claim 17 wherein the center point is substantially aligned with the first axis. 19. A container comprising: a base; a wall movable between an upright position and a collapsed position; a hinge connecting the wall to the base, the hinge including a first axis and a second axis offset from the first axis, the hinge locked when the wall is in the upright position to prevent rotation about the second axis but permit rotation about the first axis, and unlocked when the wall is not in the upright position to permit rotation about the second axis, a surface of the wall contacting a surface of the base to prevent rotation of the wall about the second axis when the wall is in the upright position. 20. The container of claim 19 wherein the base including an integral lower wall portion extending upwardly therefrom, the surface of the wall contacting the integral lower wall portion to prevent rotation of the wall about the second axis when the wall is in the upright position. 21. The container of claim 20 wherein the surface of the wall is on a lower edge of the wall and is an arcuate surface interlocking with an arcuate surface on the base to prevent the inward rotation of the wall about the second axis when the wall is in the upright position.
