Abstract:
1. A mixing container comprising: a hollow mixing bag having at least one interior wall; a mixing paddle adapted to engage a support rod mechanically coupleable to receive kinetic energy from a kinetic energy source, the mixing paddle having at least one widened paddle portion that is wider than a nominal diameter or cross-sectional width of the support rod; a coupling guide joined to the mixing bag, the coupling guide defining an aperture sized to permit pivotal arrangement of the support rod between the kinetic energy source and the mixing bag; and an integral sleeve sealingly and permanently welded proximate the coupling guide aperture to any of the bag and the coupling guide, the sleeve having a closed end protruding into the interior of the hollow bag, having at least one exterior wall, and defining a cavity containing the mixing paddle, the cavity having at least one widened cavity portion disposed about the at least one widened paddle portion; wherein the at least one interior wall of the mixing bag and the at least one exterior wall of the sleeve encloses a volume, and the sleeve serves as an isolation barrier between the volume and the mixing paddle.
