ABSTRACT:
This relates to a telescoped twin drum arrangement for disposal of hazardous materials. Most specifically there is provided a steel first and outer drum and a fibre second and inner drum. By placing the material which is to be disposed within the fibre drum and then the fibre drum within the steel drum, all government regulations with respect to the shipment of hazardous material are met. On the other hand, at the point of disposal, the fibre drum may be separately disposed of together with the hazardous material retained therein while the still clean steel drum and its cover components may be returned to the place of origin for refilling with anther fibre drum. In order to facilitate the closing of the fibre drum, there is placed in the bottom of the steel drum beneath the fibre drum an elevator or inflated support in the form of a pillow. After the fibre drum is filled and its cover placed thereon together with the associated locking band, the support is deflated so as to permit the fibre drum to be fully seated within the steel drum, after which the steel drum may be closed. If desired, the support may be reinflatable so as to lift the fibre drum partially out of the steel drum at the disposal destination so that the fibre drum may be readily gripped and lifted from the steel drum.
