Abstract
An adsorbent cartridge having an elongated hollow cylindrical body member fabricated of polyethylene, polyester or polypropylene, spun-bonded polyolefin membranes closing the open ends of the body member, adsorbent within the body member, raised splines or ribs extending longitudinally on the outer surface of the body member for causing the cartridge to have a different feel than a medicinal capsule with which it may be packaged, and circumferentially extending integrally molded bands at opposite ends of the body member for reinforcing the body member against radial deflection which could result in separation of the membranes therefrom.
