Abstract
A container adapted to increase volume contraction and reduce pressure having four panels that are adapted to contract inwardly from vacuum forces created by contraction of container contents. The container has a sidewall including four panels. The four panels are vacuum panels, including vertical transitional walls disposed between and joining the panels and the body is adapted to increase volume contraction and reduce pressure. The panels are adapted to contract inwardly in response to internal negative pressure created during hot-fill processing and subsequent cooling of a hot liquid in the container.
