Abstract:
1. A plastic container having a longitudinal axis, and comprising: an upper portion including an opening into the container; a sidewall portion extending from the upper portion to a lower portion, the lower portion including a base; and a pressure panel located in the lower portion substantially transversely to the longitudinal axis, the pressure panel being movable substantially along the longitudinal axis between an initial position and an inverted position to compensate for a change of pressure induced within the container; wherein the pressure panel comprises a centrally located push-up portion adapted to move in response to a longitudinally directed force and cause the pressure panel to at least partially invert; wherein when in the initial position a control portion of the pressure panel defines an angle with respect to the longitudinal axis and the opening into the container that is greater than about 100 degrees; and wherein the push-up portion defines an angle of inclination with respect to the longitudinal axis and the opening into the container that is less than that of the control portion.
