    摘要： A plastic container having a sidewall defining a chamber and having an opening at one end into the chamber; a base extending from the sidewall and closing the second end, the base having an outer perimeter portion defining a support structure, an axially inwardly extending perimeter wall spaced radially inwardly from the support structure forming an angle with a plane normal to an axis of the container of less than about 90°, and a flexing panel closing an end of the perimeter wall, the flexing panel moveable along an axis of the container from a first position where a central portion of the panel is below a top portion of the perimeter wall to a second position where the central portion is above the top portion of the perimeter wall to change the volume of the container; and a plurality of circumferentially spaced radial grooves on the panel.

    摘要： A container with an improved container side wall is disclosed. The improved container side wall including a top end and a bottom end, an open top and a bottom wall. The top of the container merges with the top end of the side wall and the bottom wall merges with and closes the bottom end of the side wall. The side wall also includes a plurality of ribs which protrude radially outward from an inside surface of the side wall and which are integrally displaced upon the inside surface of the side wall. These ribs cause the inside surface of the container side wall to form a varying thickness. In this manner, an improved container side wall is provided that increases the resistance of the side wall to deformation caused by internal/external positive or negative pressures without significantly increasing the overall amount of material needed to manufacturer the container. The container side wall may assume a cylindrical, rectangle, oval, or square geometry.
