Claim 1
Independent Claim
140 words
In combination with a medicament vial having a chamber with an open mouth and a plug disposed in said chamber adjacent said open mouth including a plunger portion engaging sidewalls of the chamber and an externally threaded nipple portion extending from said plunger portion toward said open mouth and terminating at an end contact surface, a cap including a base member having an inner surface and an outer surface, an internally threaded cylindrical wall extending from said inner surface and threadedly engaging said nipple portion of said plug, grip means extending from said outer surface of said base member, and rib means projecting from said inner surface of said base member and abutting said end contact surface of said plug to provide a seal therefor whereby said end contact surface of said plug is provided with positive sterile barrier protection.
Claim 2
Dependent Claim
140 words
In combination with a medicament vial having a chamber with an open mouth and a plug disposed in said chamber adjacent said open mouth including a plunger portion engaging sidewalls of the chamber and an externally threaded nipple portion extending from said plunger portion toward said open mouth and terminating at an end contact surface, a cap including a base member having an inner surface and an outer surface, an internally threaded cylindrical wall extending from said inner surface and threadedly engaging said nipple portion of said plug, grip means extending from said outer surface of said base member, and rib means projecting from said inner surface of said base member and abutting said end contact surface of said plug to provide a seal therefor whereby said end contact surface of said plug is provided with positive sterile barrier protection.
Claim 3
Dependent Claim
83 words
