Plastic container having an interactive PCR channel structure and moveable base

A beverage container, comprising:

• a base;
• a cylindrical sidewall extending from and integrally formed with the base;
• an upper region extending from the cylindrical sidewall and defining an upper opening, wherein the beverage container comprises a longitudinal axis extending in a direction from the base to the upper opening;
• and
• a plurality of continuous channels having a first as molded channel configuration formed in and extending around a circumference of the cylindrical sidewall, wherein the continuous channels are configured to resist vacuum compression in the radial or transverse direction of the beverage container;
• and
• wherein the base includes an outer wall portion extending from the lower end of the sidewall to a plurality of discontinuous footed contact surfaces for supporting the container and a plurality of webs extending continuously from the sidewall radially along the base portion toward the longitudinal axis in the transverse direction to join a push up portion, wherein each one of the webs define a web surface that is closer to the finish than the plurality of footed contact surfaces and comprises a downward and continuous surface from the sidewall to the push up portion, further wherein the base includes inner wall portions extending alternately upward from the contact surfaces and downward from the webs;
• and
• wherein after hot filling and capping and prior to cooling the sidewall and base are configured to move interactively and in differential amounts under changing pressure conditions, wherein the sidewall is configured to expand longitudinally from a first unpressurized configuration to a second pressurized configuration, and the base portion is configured to move to a different extent longitudinally from a first unpressurized configuration to a second pressurized configuration;
• and
• wherein after cooling the sidewall is configured to contract longitudinally to a third pressurized configuration, and the base is configured to move to a different extent to a third pressurized configuration, wherein a vacuum exists within the container.
