A container with an anti-nesting ledge includes a substantially tubular sidewall defining a container interior. The sidewall has a first end and a second end and is tapered from the first end toward the second end to accept a like container within the container interior. A base connected to the second end to form a bottom of the container. The sidewall includes an indentation formed between the first end and the second end. The indentation extends from the sidewall into the container interior to form an interior ledge for supporting the like container in the container interior.

What is claimed is: 1. A container comprising: a substantially tubular sidewall defining a container interior and having a first end; and a second end; an indentation formed in said sidewall between the first end and the second end and extending from the sidewall into the container interior, wherein the width of the indentation is less than the width of the container sidewall; and a base connected to the second end to form a bottom of the container; wherein the sidewall is tapered from the first end toward the second end to accept a like container within the container interior; wherein the indentation comprises a ledge for supporting the like container in the container interior, an inner wall disposed at an interior terminus of the ledge, a bottom wall disposed opposite the ledge and extending from the inner wall to the sidewall, and two end walls extending in the widthwise direction of the indentation, each end wall extending, respectively, from opposing ends of the inner wall to the sidewall; wherein the base comprises an annular wall extending from the sidewall to a base wall; and wherein the annular wall has a curvature substantially similar to a curvature of an arcuate portion of the ledge proximal the side wall. 2. The container of claim 1, wherein the inner wall is substantially parallel to the sidewall. 3. The container of claim 1, wherein the indentation is substantially rectangular in a cross section taken parallel to the sidewall. 4. The container of claim 1, wherein the ledge is concave with respect to the interior of the container. 5. The container of claim 1, having two indentations opposite one another. 6. The container of claim 1, wherein the sidewall comprises four substantially flat faces such that the container is substantially rectangular in cross-section. 7. The container of claim 6, having two indentations on faces that are opposite one another. 8. The container of claim 1, wherein the container comprises a plastic material and is formed by a blow molding process. 9. The container of claim 1, wherein the sidewall has a substantially uniform thickness from the first end to the second end. 10. The container of claim 1, wherein the annular wall is convex. 11. The container of claim 10, wherein the convex annular wall comprises a standing ring. 12. The container of claim 11, wherein a distance from a central axis of the container to the standing ring is greater than a distance from the central axis to a ledge inner periphery. 13. The container of claim 11, wherein a cross section thorough the standing ring is substantially square. 14. The container of claim 10, wherein at least a portion of said base wall is substantially perpendicular to a central axis of the container. 15. The container of claim 1, further comprising a closure attached to the first end. 16. The container of claim 15, said closure comprising a recess for accepting the base of a like container. 17. A stack of containers, comprising a plurality of containers, each container comprising: a substantially tubular sidewall defining a container interior and having a first end; and a second end; an indentation formed in said sidewall between the first end and the second end, wherein the width of the indentation is less than the width of the container sidewall; and said indentation extends from the sidewall into the container interior and comprises a ledge in the container interior, an inner wall disposed at an interior terminus of the ledge, a bottom wall disposed opposite the ledge and extending from the inner wall to the sidewall, and two end walls extending in the widthwise direction of the indentation, each end wall extending, respectively, from opposing ends of the inner wall to the sidewall; and a base connected to the second end to form a bottom of the container; wherein the sidewall is tapered from the first end toward the second end; wherein the base comprises an annular wall extending from the sidewall to a base wall; wherein the annular wall has a curvature substantially similar to a curvature of an arcuate portion of the ledge proximal the side wall; and wherein a first one of said containers is nested within a second one of said containers; the ledge of the second container is in contact with the base of the first container; and a portion of the annular wall of the first container is nested within the arcuate portion of the ledge of the second container. 18. The stack of containers of claim 17, wherein the sidewall is tapered such that the largest exterior dimension of the sidewall proximal to the base is smaller than the interior dimension of the sidewall proximal to the indentation on a side of the indentation opposite the base. 19. The stack of containers of claim 17, wherein the first container is nested within the second container without significant wedging or stacking of the containers. 20. The stack of containers of claim 17, wherein the annular wall is convex and the ledge is concave with respect to the interior of the container, wherein the radius of curvature of the convex annular wall is about the same as the radius of curvature of the concavity of the ledge.
