Abstract

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.
