PLASTIC CONTAINER HAVING AN INTERACTIVE PCR CHANNEL STRUCTURE AND MOVEABLE BASE

Abstract: the disclosure relates to a beverage container. channels of the container can have a first as molded channel configuration formed in and extending around a circumference of a sidewall of the container and can be configured to resist vacuum compression in the radial or transverse direction of the container. after hot filling and capping and prior to cooling, the sidewall and base can be configured to move interactively and in differential amounts under changing pressure conditions. the sidewall can be configured to expand longitudinally from a first unpressurized configuration to a second pressurized configuration, and the base portion can be configured to move to a different extent longitudinally from a first unpressurized configuration to a second pressurized configuration. after cooling, the sidewall can be configured to contract longitudinally to a third pressurized configuration, and the base can be configured to move to a different extent to a third pressurized configuration.
