Abstract
A blow molded container has a neck portion defining a mouth. The neck portion leads into a shoulder portion and a bottom portion forms a container base. A sidewall portion connects the shoulder portion and the bottom portion and employs a first pair of opposing convex vacuum panels and a second pair of opposing convex vacuum panels. The first pair of opposing convex vacuum panels is larger in surface area than the second pair of opposing convex vacuum panels. A vertical column at each corner of the container joins the first pair of opposing vacuum panels to the second pair of opposing vacuum panels. A structural convex arch resides above and below each convex vacuum panel. Each of the vertical columns are molded into the structural convex arches. Vacuum initiator grooves may be molded into the first and second pair of opposing vacuum panels to control vacuum panel movement.
