Abstract:
A plastic drum for the storage of liquid or other flowable materials and suitable for industrial applications. The drum consists of a circular side wall, a flat top wall and a bulged bottom wall. The top wall includes a threaded fill hole and a threaded vent. Each hole is surrounded by an upstanding undercut lip. A circular flange is located at the juncture of the top wall and the side wall. The flange extends above the plane of the top wall and beyond the outer periphery of the side wall. The walls of the drum are each of the same thickness. The circular side wall includes a plurality of elongated arcuate depressions equidistantly spaced about the periphery thereof to form strengthening ribs. The bottom wall includes a peripheral ledge projecting downward to form a planar base for the drum. The center of the bulged portion of the bottom wall is coplanar with the base.
