In a hot-fillable, blow-molded plastic container for containing a liquid filled initially in a hot state and subsequently sealed so that the cooling of the liquid creates a reduced volume in the container having a bottom portion, a shoulder portion above the bottom portion, a closable neck portion on the shoulder portion permitting filling and discharge of the liquid, and a body portion connecting the bottom and shoulder portions, the body portion having an arcuate front panel extending between the bottom and shoulder portions and an arcuate rear panel located diametrically opposite the front panel and extending between the bottom and shoulder portions, the body portion having a pair of flex panels set inwardly from and extending between the shoulder and bottom portions on opposite sides of the container, the flex panels extending between the front and rear panels and each flex panel having formed therein an inwardly recessed rigid grip panel for receiving a person\s thumb and fingers on opposite sides of the container when the rear panel is engaged by a person\s palm, the improvement wherein each of the grip panels has an elongate rib along an inwardly most recessed edge of each of the grip panels to prevent inverting of the grip panels, each of the grip panels having a planar grip surface defined by a plurality of coplanar flat portions, and a continuous narrow transitional wall section extending around said planar grip surface away from the rear panel, said planar grip surface intersecting said transitional wall section at an included obtuse angle of up to about 120°, said rib extending inwardly into the interior of the container and out of the plane of the planar grip panel and being located at the intersection of said planar grip panel and said transitional wall section, whereby the container grip panel maintains its structural integrity against everting during hot-filling and after being cooled, and later opened.
