A plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.

1. A method of compensating for vacuum pressure changes within a plastic container, the method comprising: a. Filling a plastic container with a heated liquid, the container having a longitudinal axis, an upper portion having an opening into the container, a body portion extending from the upper portion to a lower portion, the lower portion including a base, the base closing off an end of the container, the container having at least one substantially transversely oriented pressure panel located in the lower portion, a hinge circumscribing the pressure panel, wherein the lower portion includes an instep recessed inwardly into the container from a standing surface and the hinge joins the pressure panel to the instep, wherein the instep is recessed into the container to such an extent that the entire pressure panel is above the standing surface, the pressure panel comprising a control portion being inclined at an angle of between 100° and 135° relative to the opening into the container and a plane parallel to the longitudinal axis, the pressure panel comprising a centrally located push-up portion;b. Capping or sealing the container;c. Cooling the heated liquid to create a vacuum pressure; andd. Repositioning the base about the hinge from the inclined position to an inverted position by applying an external mechanical force to the base to reduce the vacuum pressure within the container. 2. The method of claim 1, comprising transporting the container before or after any of steps (a) through (d). 3. The method of claim 1, wherein the centrally located push-up portion comprises a portion that is inclined at an angle relative to a plane parallel to the longitudinal axis and the opening into the container that is less than the control portion. 4. The method of claim 1, wherein repositioning the base causes a rise in pressure in the container. 5. The method of claim 1, wherein a longitudinal force is applied to the base to fold the pressure panel inwardly. 6. The method of claim 1, wherein the push-up portion is configured to receive the mechanical force. 7. The method of claim 1, wherein the push-up portion is inwardly recessed. 8. The method of claim 1, wherein the container is adapted to stand upright on a flat surface. 9. The method of claim 1, wherein the body portion includes a portion that deforms inwardly and outwardly under pressure change. 10. The method of claim 9, wherein the body portion that deforms inwardly reduces a portion of an internal vacuum pressure during the step of cooling the heated liquid. 11. The method of claim 10, wherein said repositioning the base about the hinge to an inverted position reduces a second portion of the internal vacuum pressure. 12. The method of claim 9, wherein the body portion that deforms inwardly and outwardly comprises at least one supplemental vacuum panel formed therein. 13. The method of claim 12 wherein a first portion of the vacuum pressure created during the step of cooling the heated liquid is reduced by the at least one supplemental vacuum panel. 14. The method of claim 13 wherein the step of repositioning the base from the inclined position to an inverted position removes a second portion of the vacuum pressure. 15. The method of claim 1, wherein the body portion includes at least one portion that is strengthened against deformation. 16. The method of claim 15, wherein the body portion that is strengthened against deformation comprises an annular or circumferential rib structure or panel portion. 17. The method of claim 1, wherein the container is adapted to stand upright on a flat surface when the pressure panel is in the outwardly inclined position. 18. The method of claim 1, wherein said repositioning the base about the hinge to an inverted position repositions the centrally located push-up portion and does not reposition the instep. 19. The method of claim 18, wherein the body portion includes at least one portion that is strengthened against vacuum pressure deformation. 20. A method of compensating for vacuum pressure changes within a plastic container, the method comprising: a. Filling a plastic container with a heated liquid, the container having a longitudinal axis, an upper portion having an opening into the container, a body portion extending from the upper portion to a lower portion, the body portion including a vacuum portion that is relatively free of structural reinforcement and configured to deform inwardly and outwardly under pressure change, the lower portion including a base, the base closing off an end of the container, wherein the base includes a standing surface, the container having at least one substantially transversely oriented pressure panel located in the lower portion, a hinge circumscribing the pressure panel, wherein the lower portion further includes an instep recessed inwardly into the container from the standing surface and connecting to the pressure panel, wherein the instep is recessed into the container to such an extent that the entire pressure panel is above the standing surface, the pressure panel comprising a control portion being inclined at an angle of between 100° and 135° relative to the opening into the container and a plane parallel to the longitudinal axis, the pressure panel comprising a centrally located push-up portion;b. Capping or sealing the container;c. Cooling the heated liquid to create a vacuum pressure;d. Compensating a first portion of the vacuum using the vacuum portion; ande. Repositioning the pressure panel about the hinge from the inclined position to an inverted position by applying an external mechanical force to the base to reduce a second portion of the vacuum pressure within the container. 21. The method of claim 20, wherein said pressure panel includes a plurality of flutes, ribs or creases configured to flex and facilitate repositioning of the pressure panel. 22. The method of claim 20, wherein the body portion includes at least one portion that is strengthened against deformation. 23. The method of claim 22, wherein the body portion that is strengthened against deformation comprises an annular or circumferential rib structure or panel portion. 24. The method of claim 23, wherein the body portion comprises more than one annular or circumferential rib structure. 25. A method of compensating for vacuum pressure changes within a plastic container, the method comprising: a. Filling a plastic container with a heated liquid, the container having a longitudinal axis, an upper portion having an opening into the container, a body portion extending from the upper portion to a lower portion, the lower portion including a base, the base closing off an end of the container, the container having at least one substantially transversely oriented pressure panel located in the lower portion, a hinge circumscribing the pressure panel, wherein the lower portion includes an instep recessed inwardly into the container from a standing surface and the hinge joins the pressure panel to the instep, wherein the instep is recessed into the container to such an extent that the entire pressure panel is above the standing surface, the pressure panel comprising a control portion being inclined at an angle of between 100° and 135° relative to the opening into the container and a plane parallel to the longitudinal axis, the pressure panel comprising a centrally located push-up portion;b. Capping or sealing the container;c. Cooling the heated liquid to create a vacuum pressure; andd. Repositioning the base about the hinge from the inclined position to an inverted position by applying an external mechanical force to the base to reduce the vacuum pressure within the container; andwherein said pressure panel includes a plurality of flutes, ribs or creases configured to flex and facilitate repositioning of the pressure panel.
