ABSTRACT:
A cylindrically shaped, drum-type container includes a barrel formed of one or more like, helically wound lengths of skelp having contacting longitudinal edges interlocked in rolled seams following the helix. By forming corner notches in the several lengths of skelp, recesses are defined by communicating notches of adjacent lengths, at the opposite ends of each helical seam. The recesses provide clearance for rolling the ends of the lengths of skelp into interlocking engagement with the peripheries of a pair of drum heads. The helical seams, and also the peripheral seams connecting the barrel to the drum heads, are adapted to be filled with a flowable sealant, in those containers that must be made fluid-tight against the loss of liquid materials confined therein.
