Bottle with non-everting hand grip

Claim 1

A thin-walled container composed of a strain-hardened polymer, comprising a neck portion defining an opening, a bottom portion, and a body portion intermediate the neck and bottom portions, the body portion including a generally cylindrical side wall of diameter D and an opposed pair of indentations to permit the container to be grasped between a thumb and fingers of one hand, the indentations each comprising a first vertical surface and a second vertical surface, the surfaces having outside vertical edges which are continuously joined to the cylindrical side wall, the first and second surfaces of each indentation having a common edge continuously joining the two surfaces, the second surface being inclined with respect to the first surface at an obtuse angle, and a plurality of vertically spaced-apart horizontal ribs extending continuously over at least a major portion of the horizontal width of both the first and second surfaces and the common edge, the outermost surfaces of the ribs extending parallel to the first and second surfaces and including a demarcation coincident with the common edge for inhibiting the everting of the indentations.
