Abstract

A container body and base being lightweight structures designed to accommodate vacuum forces either simultaneously or in sequence. The container body and base each absorb a significant percentage of the vacuum. By utilizing a lightweight base design to absorb a portion of the vacuum forces enables an overall light-weighting, design flexibility, and effective utilization of alternative vacuum absorbing capabilities on the container body.
