ABSTRACT OF THE DISCLOSURE A right circular cylindrical end of an industrial con- tainer or drum shell is embraced by a peripheral channel on an end closure which channel is, in turn, embraced by a channel shaped chime ring, and the assembly thus produced is compressed in the radial direction and curled radially inwardly to provide an end seam that has the shape of the radially outer surface of a torus. A circumferential groove is formed in the shell a pre- determined distance from the rim of said shell end, and the radially outer skirt of the chime ring extends into said groove. For reclamation the curled seam is straightened and the extending portion of the radially outer skirt of the chime ring is severed from the remainder of the chime ring to permit axial separation of said remainder of the chime ring, followed by the end closure, from the shell, whereby the shell and end closure can be reconditioned and reused. - 11 -
