ABSTRACT:
A thin-walled plastic bottle has hand-grip indentations each of which are formed by a pair of vertical surfaces unitarily joined together along a common edge and inclined with respect to each other at an obtuse angle, generally greater than about 145.degree.. A plurality of horizontal reinforcing ribs protrude outward over major portions of the first and second surfaces including the common edge, the reinforcing ribs inhibiting the everting of the hand-grip indentations.
