ABSTRACT:
A container of a heat set plastic material adapted for hot fill applications includes a plurality of elongated vertically oriented vacuum panels in its sidewall and first and second circumferentially extending inwardly directed reinforcement ribs which are located in the label mounting areas above and below the vacuum panels and which cooperate with upper and lower label bumpers of the container to support the upper and lower edges of the vacuum panels permitting the center portions of the panels to flex inward during filling and sealing the container with a hot liquid, but resisting deformation of the container sidewall in compensating for the hot-fill vacuum.
