摘要： A plunger cover for use with a syringe includes a sealing portion adapted to form a seal with the syringe and a central portion adapted to contact fluid within the syringe. The central portion can, for example, be more rigid than the sealing portion. The sealing portion and the central portion are connected in an overmolding process. The sealing portion can, for example, be formed from a thermoplastic elastomer or a thermoplastic polyurethane. The central portion can, for example, be formed from polypropylene, acrylonitrile butadiene styrene, polycarbonate or copolymers thereof.
