Abstract
A syringe assembly includes a plastic cap (20) that has an end wall (22) and a side wall (24). The end wall (22) preferably includes a plug portion (64) that extends away from an inner surface (62) of the end wall (22). The side wall (24) includes an inner surface (28) that has an engaging portion that sealingly engages a corresponding surface on a syringe. The engaging portion preferably includes two generally annular ribs (34) and (36). An interference fit is provided between the engaging portion and a corresponding surface on the syringe to maintain a sterile seal where the engaging portion contacts the syringe. The plug portion is received within an opening in the syringe and maintains a sterile seal at that point while simultaneously maintaining any medicament within the syringe.
