Abstract
A thermoplastic blow-molded drum employs, in place of the conventional flat circular top, or a slightly spherical or radially rounded top, a top having a cylindrical surface over most of its area. The cylindrical surface is of a relatively wide radius and based on an axis perpendicular to the drum; it permits the trouble-free use of paper labels and the like which will conform to the cylindrical surface, while also strengthening the corners of the drum chime at the ends of the cylindrical surface by permitting the parison to conform to a surface intersection having less area than that of the sharp corners of the prior art, resulting in a greater thickness and more strength.
