A mold for forming a plastic container having an integrally formed standing ring. The mold includes a first mold portion and a second mold portion. The second mold portion is movable relative to the first mold portion. The first mold portion and the second mold portion together define at least in part a mold cavity for molding a plastic container. The first mold portion and the second mold portion together define a standing ring slot for forming a standing ring on a base portion of the plastic container. The standing ring slot is defined at an interface between the first mold portion and the second mold portion.

1. A mold for forming a plastic container having an integrally formed standing ring, said mold comprising: a first mold portion;a second mold portion movable relative to said first mold portion, said first mold portion and said second mold portion together defining at least in part a mold cavity for molding a plastic container; anda vent slot extending through said second mold portion, said vent slot being in fluid communication with said mold cavity when said second mold portion is in a first position relative to said first mold portion, said vent slot being fluidly separated from said mold cavity when said second mold portion is in a second position relative to said first mold portion;wherein said first mold portion and said second mold portion together define a standing ring slot for forming a standing ring on a base portion of the plastic container, said standing ring slot being defined at an interface between said first mold portion and said second mold portion. 2. The mold according to claim 1, further comprising: a positive stop extending from at least one of said first mold portion and said second mold portion, said positive stop forming a predetermined edge along a distal end of the standing ring. 3. The mold according to claim 1 wherein said standing ring slot is adjustable. 4. The mold according to claim 1 wherein said standing ring slot is adjustable in response to the addition of insert rings between at least a portion of said first mold portion and said second mold portion. 5. The mold according to claim 1 wherein said standing ring slot is oriented at an angle greater than 0° and less than 90° relative to a longitudinal axis of said mold cavity. 6. The mold according to claim 1, wherein the mold is configured to form the standing ring as a molding flash including a flat standing surface. 7. The mold according to claim 1, wherein the mold is configured such that relative movement between the first mold portion and the second mold portion forms the standing ring as a molding flash including an even standing surface. 8. The mold according to claim 1, wherein the mold is configured such that relative movement between the first mold portion and the second mold portion forms the standing ring as a molding flash including at least one of a stable heel and a stable foot. 9. The mold according to claim 1, wherein the standing ring slot is configured to form the standing ring as a thin, generally upstanding, standing ring. 10. The mold according to claim 1, further comprising a positive stop extending from at least one of the first mold portion and the second mold portion, the positive stop configured to form the standing ring as a truncated standing ring. 11. The mold according to claim 1, further comprising a positive stop extending from at least one of the first mold portion and the second mold portion, the positive stop configured to shape the standing ring. 12. The mold according to claim 1, wherein the mold is configured to form the standing ring with a strength sufficient to support the plastic container upright. 13. A mold for forming a plastic container having an integrally formed standing ring, the mold comprising: a first mold portion;a second mold portion;a drive device configured to move the first mold portion relative to the second mold portion; anda standing ring slot defined between the first mold portion and the second mold portion, the standing ring slot configured to form the standing ring at a base portion of the plastic container;wherein the standing ring slot is adjustable to provide the standing ring with different shapes. 14. The mold of claim 13, wherein the mold is configured to form the standing ring as a molding flash including a flat standing surface. 15. The mold of claim 13, wherein the mold is configured such that movement of the first mold portion relative to the second mold portion forms the standing ring as a molding flash including at least one of a stable heel and a stable foot. 16. The mold of claim 13, wherein the standing ring slot is configured to form the standing ring as a thin, generally upstanding, standing ring. 17. The mold of claim 13, further comprising a positive stop extending from at least one of the first mold portion and the second mold portion, the positive stop configured to form the standing ring as a truncated standing ring. 18. The mold of claim 13, further comprising a positive stop extending from at least one of the first mold portion and the second mold portion, the positive stop configured to shape the standing ring. 19. The mold of claim 13, wherein the mold is configured to form the standing ring with a strength sufficient to support the plastic container upright. 20. The mold of claim 13, further comprising a vent slot extending through said second mold portion, said vent slot in fluid communication with said mold cavity when said first and second mold portions are in a first position relative to each other, and said vent slot is fluidly separated from said mold cavity when said first and second mold portions are in a second position relative to each other. 21. A mold for forming a plastic container having an integrally formed standing ring, said mold comprising: a first mold portion; anda second mold portion movable relative to said first mold portion, said first mold portion and said second mold portion together defining at least in part a mold cavity for molding a plastic container;wherein said first mold portion and said second mold portion together define a standing ring slot for forming a standing ring on a base portion of the plastic container, said standing ring slot being defined at an interface between said first mold portion and said second mold portion; andwherein said standing ring slot is adjustable. 22. The mold of claim 21, wherein said standing ring slot is adjustable in response to the addition of insert rings between at least a portion of said first mold portion and said second mold portion. 23. A mold for forming a plastic container having an integrally formed standing ring, the mold comprising: a first mold portion;a second mold portion;a drive device configured to move the first mold portion relative to the second mold portion;a standing ring slot defined between the first mold portion and the second mold portion, the standing ring slot configured to form the standing ring at a base portion of the plastic container; anda vent slot extending through said second mold portion, said vent slot in fluid communication with said mold cavity when said first and second mold portions are in a first position relative to each other, and said vent slot is fluidly separated from said mold cavity when said first and second mold portions are in a second position relative to each other.
