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.
