Containers used for storing and dispensing liquids for medical applications and formed in a one-piece, molded construction include a neck defining a dispensing outlet and an annular lip, a closure for the outlet and a frangible section coupling the closure to the neck. An article of manufacture and a method are provided where a frangible section couples the closure to the neck and defines an annular channel between the outlet lip and the closure. Completing the article of manufacture and method, the neck has an overmold which engages the closure whereby the molding of the overmold may tend to reduce the bio-burden at the area of contact of the overmold and the neck and whereby displacement of the overmold ruptures the frangible section permitting removal of the overmold and closure for opening of the container.
