ABSTRACT:
An improved powder drum for containing a dry powder having a drum portion and a cover portion. The drum portion having a side wall with a predetermined configuration, an open top end and a bottom end with an aperture therein, having a predetermined configuration. A closure is provided on the open top end of the drum portion that completely closes the top end. The cover portion has a side wall with substantially the same configuration as the predetermined configuration of the side wall of the drum portion and telescopes over the side wall of the drum portion. The cover portion also has a bottom end having a concavity that mates with and extends substantially through the aperture in the bottom end of the drum portion. The concavity has substantially the same configuration as the aperture. A flocked material substantially covers an inner surface of the side wall, the bottom end and the concavity of the cover portion and seals the assembled drum portion and cover portion. During assembly, the flock material substantially prevents the dry powder from escaping from the drum portion.
