Abstract:
1. A plastic container comprising: an upper portion including a finish defining an opening into the container; a lower portion including a base defining a standing surface; a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis; and at least one substantially transversely-oriented pressure panel located in the lower portion and forming part of the base, the base including a centrally located inward projection and an instep or recess between the pressure panel and the standing surface, the pressure panel being movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure induced inside the container; and an inner wall extending from the standing surface to the pressure panel; wherein the pressure panel is connected to the instep by a hinge structure; wherein the standing surface defines a standing plane orthogonal to the longitudinal axis, wherein the pressure panel includes a portion that is outwardly inclined greater than about 10 degrees with respect to the standing plane when in the outwardly-inclined position, and the inner wall has a length substantially parallel to the longitudinal axis whereby the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position with the portion outwardly inclined greater than about 10 degrees with respect to the standing plane, wherein the base is configured to be pushed by a force to facilitate movement of the pressure panel from the outwardly-inclined position to the inwardly-inclined position.
