A lightweight plastic container having improved strength and rigidity characteristics for a given amount of plastic material is provided. The container is of one-piece thin-walled construction having four generally flat sidewalls interconnected by curved corner portions and having a bottom portion interconnected to the flat sidewalls by curved base portions and further having an integral handle formed within the bottle profile. The container incorporates a pair of longitudinally extending ribbing structures in a pair of opposed curved corner portions and other inventive constructional features enabling the lightweight container to withstand hydrostatic forces without buckling or dimpling as well as heavier conventionally constructed plastic containers.
