AbstractA container made of thermoplastic material such as PET includes a bottom portion, a neck portion, and an intermediate body portion including at least two circumferential rows of panels for providing controlled volumetric reduction of the container. A land separates each adjacent pair of panels in each row. The rows of panels are staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row. The design distributes circumferentially the vertical and horizontal support for any label applied to the label panel of the container while still providing the desired panel movement in response to the existence of a partial vacuum within the container due to hot filling.
