An integrally molded plastic drum having a cylindrical body, a top wall, and a bottom wall is provided. The bottom wall has a central recessed portion and an annular generally flat horizontal bottom wall portion surrounding the central recessed portion. The annular bottom wall portion has a first recess, a second recess, and a discrete hand engageable lifting indentation therein. The central recessed portion, first and second recesses, and the discrete lifting indentation collectively contain the molding parting line extending across the bottom wall of the drum. The top wall of the drum has a central concave portion which serves as a collection well in the event of spillage and also serves to facilitate the drainage of the drum when the drum is inverted. The top wall defines a pair of spaced apart bungholes therein. The bungholes are positioned in a diametrically opposing relation, with one of the bungholes serving as a filling spout and the other bunghole serving as a pouring spout. The top wall defining the pair of bungholes also defines internal threads for each bunghole, where the internal threads for the pouring spout are coarser than the internal threads for the filling spout. The discrete hand engageable lifting indentation is positioned directly below the filling spout and is of such a size as to be easily grasped by one\s hand for manual lifting of the drum.

An integrally molded plastic drum comprising: a cylindrical body; a top wall and a bottom wall integrally molded with respective upper and lower ends of said cylindrical body; means defining a pair of spaced apart bungholes formed in said top wall and extending upwardly from the top wall, the spacing between said pair of bungholes being greater than the spacing from each of said bungholes to an adjacent periphery of said top wall; said top wall having a concave portion defining central portions of said top wall, said concave portion serving as a collection well in the event of spillage and also serving to facilitate the drainage of the drum when the drum is inverted; said bottom wall having a discrete hand engageable lifting indentation therein of such a size as to be grasped manually by a plurality of fingers of one\s hand for manual lifting of the drum; an annular chime integrally formed with the upper end of said cylindrical body and extending upwardly thereabove and terminating above the height of said means defining said pair of bungholes; and a molding parting line, inherent in molding, which circumscribes the drum and protrudes outwardly from the top wall, bottom wall and cylindrical body of the drum and defines a ridge that bisects the molded drum in longitudinal halves, said bottom wall further having a central recessed portion and an annular generally flat horizontal bottom wall portion surrounding said central recessed portion, said annular bottom wall portion having first and second recesses therein, and wherein said central recessed portion, said first and second recesses and said discrete lifting indentation collectively contain said molding parting line extending across the bottom wall of the drum so that the molding parting line is recessed and will not interfere with the drum resting flat on its bottom wall.
