A stackable blow-molded container having a bottom wall that includes a parting line ridge projecting downwardly from a lower surface of the bottom wall, and a cap comprising a top panel having a plurality of upwardly extending projections formed on the upper surface of the top panel. The projections are circumferentially spaced apart about the upper surface of the top panel so as to define a plurality of substantially straight channels between the projections, the channels being angularly spaced apart, each channel eing configured to receive the parting line ridge on the bottom wall of another one of the containers stacked atop the cap. The projections have sufficient height (i.e., equal to or greater than the height of the parting line ridge) such that they are able to contact the bottom wall atop the cap and form a stable base therefor.
