A base for a plastic container is disclosed. The base includes a central vertical axis; an outer supporting annular portion for supporting said container on a surface; a central portion of the base, the central portion provided about said central vertical axis; and a base portion. The base portion extends between the annular portion and the central support portion of the base. The base portion includes at least two lugs that extend radially from a position adjacent the annular portion towards the central portion, the lugs including at least two stepped segments.

What is claimed is: 1. A base for a plastic container, the base having a central vertical axis and comprising: an outer supporting annular portion for supporting said container on a surface; a central portion of the base, the central portion provided about said central vertical axis; and a base portion extending between the annular portion and the central support portion of the base; wherein the base portion includes at least two lugs that extend radially from a position adjacent the annular portion towards the central portion, each lug provided between the annular portion and the central portion; and each lug comprising at least two vertical segments and at least two bottom segments, each of the at least two bottom segments is substantially horizontal, and each of the at least two bottom segments is offset vertically from, and excludes, the central portion and the annular portion. 2. The base of claim 1, wherein the base portion includes an outer annular region surrounding the central portion of the base. 3. The base of claim 1, wherein a first vertical segment and a first bottom segment define a first stepped segment, the first vertical step segment extending downwardly from a position about the central portion. 4. The base of claim 3, wherein the first vertical segment of the first stepped segment is the greatest vertical height of the stepped segments. 5. The base of claim 3, wherein the first vertical step segment forms an angle that is one degree or greater from vertical. 6. The base of claim 1, wherein the angle of the vertical component of each stepped segment increases moving along the lug in a direction from the central portion. 7. The base of claim 1, wherein each of the bottom segments forms an angle with the horizontal that is from 0° to 10°. 8. The base of claim 1, wherein the lug includes an inside radius and an outside radius, and the inside radius and the outside radius are a minimum of 0.005 inches and a maximum of 0.250 inches. 9. The base of claim 1, wherein the width of the stepped segments of each lug increases in a direction moving from the central portion. 10. The base of claim 1, wherein the central portion has a vertical height that is less than 0.125 inches. 11. The base of claim 10, wherein the central portion has a radius from 0.125 inches to 0.750 inches. 12. The base of claim 1, wherein the overall height of the base is between 0.300 inches and 1.000 inches. 13. The base of claim 1, wherein the base portion includes six or more lugs. 14. The base of claim 1, wherein generally smooth land portions are interspersed between each of the at least two lugs. 15. The base of claim 14, wherein the surface area of the lugs is greater than the surface area of the interspersed lands. 16. The base of claim 1, wherein the central portion includes a convex portion that extends downwardly. 17. The base of claim 1, wherein the base is biaxially oriented. 18. The base of claim 1, wherein the base is comprised of polyethylene terephthalate. 19. The base of claim 1, wherein the lugs extend outwardly from the plane of the base. 20. The base of claim 1, wherein each of the lugs includes a stepped segment that includes a portion of the stepped segment that is on a common plane with the other stepped segments. 21. The base of claim 1, wherein the base includes an elevated ring portion between the outer supporting annular portion and the base portion. 22. The base of claim 21, wherein the base includes at least two elevated ring portions. 23. The base of claim 22, wherein elevation of the elevated ring portions above said surface increases in a radially inward direction relative to the central axis. 24. A base for a plastic container, the base having a central vertical axis and comprising: an outer supporting annular portion for supporting said container on a surface; a central portion of the base, the central portion provided about said central vertical axis; and a base portion extending between the annular portion and the central support portion of the base, the base portion including an outer annular region and at least two lugs that extend radially from a position adjacent the annular portion towards the central portion, each lug provided between the annular portion and the central portion; and each lug comprising at least two vertical segments and at least two bottom segments, each of the at least two bottom segments is substantially horizontal, and each of the at least two bottom segments is offset vertically from, and excludes, the central portion and the annular portion; wherein the angle of the vertical segments increases moving along each lug in a direction from the central portion, and the widths of the stepped segments of each lug increases in a direction moving from the central portion. 25. The base of claim 1, wherein the outermost radial portion of the supporting annular portion extends to the outermost diameter of said container. 26. The base of claim 1, wherein the bottom segments of each lug do not circumferentially extend around the base portion. 27. The base of claim 1, wherein the substantially horizontal bottom segments range from about 0° to about 10° with respect to horizontal. 28. The base of claim 14 wherein the land portions includes a first ring. 29. The base of claim 14 wherein the land portions includes a first ring and a second ring, the second ring positioned closer to the central portion.
