Abstract: A heat set container having a shoulder portion and a sidewall portion extending from the shoulder portion to a base. The base closes off an end of the container. The shoulder portion, the sidewall portion, and the base cooperate to define a receptacle chamber within the container into which product can be filled. The sidewall portion defines a major container diameter of the container. The sidewall portion includes an upper vacuum absorbing region joined to a lower vacuum absorbing region at a reduced waist section. The reduced waist section forms a minor container diameter which is less than the major container diameter. In some embodiments, such configuration forms an hourglass, heat-set container, wherein the upper vacuum absorbing region and the lower vacuum absorbing region are collectively shaped to provide flexible absorption of an internal vacuum within the receptacle chamber.

Abstract: A plastic container includes an upper portion having a mouth defining an opening into the container. A shoulder region extends from the upper portion. A sidewall portion extends from the shoulder region to a base portion. The base portion closes off an end of the container. The sidewall portion is defined in part by at least one arcuately formed rib having a body portion and opposite ends. The body portion curves from a central portion toward the base portion at each of the opposite ends.
