Abstract:
1. An attachment system for use between a charging device and a drum utilizing a flexible containment structure comprising: a rigid mechanical docking surface, the rigid mechanical docking surface being mounted on the charging device and having an outer periphery; a docking interface comprised of a first elastomeric, thermoplastic material; said docking interface comprising an inner circumferential surface and an outer circumferential surface; the inner circumferential surface further comprising a molded edge; the molded edge comprising an integrally molded raised portion; the outer circumferential surface being oriented perpendicular to the inner circumferential surface and being configured to integrally connect to a second thermoplastic material; the second thermoplastic material comprising a flexible containment structure in the form of an inextensible thin film sleeve having an inner periphery greater than the outer periphery of the rigid mechanical docking surface, the thin film sleeve being in sealed engagement with the outer circumferential surface of the annular thermoplastic material, said sealed engagement being one selected from the group consisting of direct heat seal and bonding; the rigid mechanical docking interface further comprising a corrugated surface, wherein the corrugated surface contains at least one ridge and at least one groove and wherein the corrugated surface is configured to form a removable seal with the inner circumferential surface of the docking interface, where the integrally molded raised portion of the docking interface is in removable contact with one of the at least one groove, and one of the at least one ridge is in contact with the inner circumferential surface of the docking interface.
