The invention claimed is: 1. A plastic container comprising: a heel portion having an enclosed base; a body portion transitioning into the heel portion, the body portion having a plurality of generally flat panels forming a generally tubular structure in cross-section, wherein each of the panels is connected to an adjacent panel with a chamfered post and wherein the body portion includes at least one vertically oriented rib located adjacent to each of the chamfered posts, wherein each of the vertically oriented ribs are substantially equal in size; a bell portion transitioning into the body portion; and a finish attached to the bell portion and defining an opening. 2. The plastic container of claim 1, wherein adjacent panels of the body portion form an angle in the range of about 60° to about 90°. 3. The plastic container of claim 1, wherein the plurality of generally flat panels includes four generally flat panels and the generally tubular cross-section is approximately square shaped. 4. The plastic container of claim 1, wherein the transition between the bell portion and the body portion includes at least one upper bumper and the transition between the body portion and the heel portion includes a lower bumper. 5. The plastic container of claim 1, wherein the body portion includes two vertically oriented ribs at each of the chamfered posts, one vertically oriented rib on either side of each of the chamfered posts. 6. The plastic container of claim 4, wherein the upper bumper includes a plurality of discontinuous, substantially horizontal ribs. 7. The plastic container of claim 4, wherein the lower bumper includes a plurality of discontinuous, substantially horizontal ribs. 8. The plastic container of claim 6, wherein the upper bumper includes four discontinuous, substantially horizontal ribs. 9. The plastic container of claim 7, wherein the lower bumper includes four discontinuous, substantially horizontal ribs. 10. The plastic container of claim 4, wherein the upper bumper includes at least one ring extending around the plastic container. 11. The plastic container of claim 4, wherein the lower bumper includes at least one ring extending around the plastic container. 12. The plastic container of claim 1, wherein the base is a push-up base. 13. The plastic container of claim 1, wherein at least one of the plurality of panels is a vacuum panel. 14. The plastic container of claim 1, wherein the body portion has a cross-sectional diameter, which is about 86% to about 94% of the cross-sectional diameter of one of the heel and bell portions. 15. The plastic container of claim 1, wherein the heel portion and the bell portion are generally circular in cross-section. 16. The plastic container of claim 1, wherein the body portion, the heel portion, and the bell portion are adapted for hot-fill applications. 17. The plastic container of claim 1, wherein the body portion, the heel portion, and the bell portion are blow molded PET. 18. A method for preventing deformation of a plastic container comprising: providing a heel portion having an enclosed base; providing a body portion transitioning into the heel portion, the body portion having a plurality of generally flat panels forming a generally tubular structure, wherein each of the panels is connected to an adjacent panel with a chamfered post and wherein the body portion includes at least one vertically oriented rib located adjacent to each of the chamfered posts; wherein each of the vertically oriented ribs are substantially equal in size; providing a bell portion transitioning into the body portion; and providing a finish attached to the bell portion and defining an opening. 19. The method of claim 18, wherein the providing the body portion step includes providing four generally flat panels as the plurality of generally flat panels and the generally tubular structure is substantially square shaped. 20. The method of claim 18, wherein the providing the body portion step includes providing a vacuum panel as at least one of the plurality of panels. 21. The method of claim 18, wherein the step of providing the heel portion provides a heel portion that is generally circular in cross-section. 22. The method of claim 18, wherein the step of providing the bell portion provides a bell portion that is generally circular in cross-section. 23. A method of manufacturing a blow molded PET container, comprising: forming a container having a heel portion region defining an enclosed base; a body portion region transitioning into the heel portion region, the body portion region having a plurality of generally flat panels forming a generally tubular structure, wherein each of the panels is connected to an adjacent panel with a chamfered post and wherein the body portion region includes at least one vertically oriented rib located adjacent to each of the chamfered posts; wherein each of the vertically oriented ribs are substantially equal in size; a bell portion region transitioning into the body portion region; and a finish region attached to the bell portion region and defining an opening. 24. The method of claim 23, wherein the plurality of generally flat panels is four generally flat panels and the generally tubular structure is substantially square shaped. 25. The method of claim 23, wherein at least one of the flat panels is a vacuum panel. 26. The method of claim 23, wherein the heel portion is generally circular in cross-section. 27. The method of claim 23, wherein the bell portion is generally circular in cross-section.
