Abstract

A sterile closure assembly for a container or vial includes an elastomeric closure for sealing the open top of a medicament container. The elastomeric closure features a plug for sealing the open top of the container and a top surface facing away from the open top of the container. A washer is secured in surface contact with the top surface of the closure. The washer defines an opening that delimits an access area on the top surface of the closure for access by a fluid delivery device such as a syringe. A membrane is removably secured over the washer and hermetically encloses the access area of the elastomeric closure. The sterile closure assembly can be provided pre-assembled in a sterile state to assure the sterility of the top surface of the closure, obviating the need to sterilize the top surface of the closure, such as with an alcohol solution, prior to use of the vial.
