Abstract
Abstract A blow molded bottle comprising oblong depressions in opposed major sides of the bottle, the bottom of the oblong depressions being joined at the center of the bottle. Extending from the major axes ends of the oblong depressions is a single depressed rib circumferentially extending about the bottle. The joined oblong depressions and circumferential rib substantially increase the rigidity of the major sides of the bottle allowing a substantial decrease in bottle wall thickness and attendant material weight.

Claim 1
Independent Claim
93 words
A thin-walled substantially parallelepiped bottle having two opposed sides, a top, a bottom, and two ends, the top, bottom and ends each of less area than each side, oblong depressions having major and minor axes in the opposed sides, said oblong depressions extending inwardly being joined together, and a circumferential depressed rib extending about the bottle generally in the direction of the largest dimension of the opposed sides to join the oblong depressions into a continuous rib about the bottle, said rib joining the oblong depressions along the major axes of the depressions.
Claim 2
Dependent Claim
