INVERTING VACUUM PANELS FOR A PLASTIC CONTAINER

摘要

A sidewall portion (18) of a plastic container (10) adapted for vacuum pressure absorption. The sidewall portion including generally rectangular shaped vacuum panels (32) equidistantly spaced about the container. The vacuum panels being defined in at least part by an upper portion (60), a central portion (62) and a lower portion (64) formed in a compound curve shape. The vacuum panels being moveable to accommodate vacuum forces generated within the container thereby decreasing the volume of the container.
