Abstract
A squeezable container with a paneled side wall which resists permanent deformation or denting when squeezed, and which preferably can be hot-filled. The container can be made substantially thinner than known hot-fill containers and includes a stepped vacuum panel profile for greater flexibility and resilience (bounce back). A circumferential ring is provided in the side wall to prevent ovalizing. The post walls (surrounding the vacuum panels) are stiffened to prevent vacuum collapse, by providing a substantially perpendicular junction between the vacuum panel and post wall, sufficient post wall depth, and/or reinforcing ribs in the post walls.
