Abstract
A hot-fill PET container which includes opposed hand grip sections in the sidewall enabling the container to be grasped between the thumb and fingers of one hand to facilitate handling of the container and pouring of liquid from the container. Each hand grip section includes an outwardly bulged surface having an outside edge and an integral hinge enabling opposite bulged surfaces to invert and collapse inwardly toward each other to accommodate internal forces tending to collapse the container sidewall inwardly due to filling of the container with liquid at an elevated temperature and subsequent cooling of the liquid.
