Sterile closure assembly for sealing a medicament container
First Claim
1. A sterile closure assembly for sealing a medicament container having an open top surrounded by a rim having an upper surface and a lower surface, said sterile closure assembly comprising:
- an elastomeric closure for sealing the open top of the container, the elastomeric closure including a plug and a flange portion extending adially beyond the plug for sealing the open top of the container and a top surface for facing away from the open top of the container, with the top surface of the elastomeric closure including an access area;
a washer secured in surface contact with the top surface of the elastomeric closure, the washer having an upper surface and a bottom surface and an opening over the access area of the top surface of the elastomeric closure; and
a membrane removably sealed to the upper surface of the washer and hermetically enclosing the opening over the access area of the top surface of the elastomeric closure; and
a crimping cap for engaging the upper surface of said washer and the rim of the container and for sealingly retaining the elastomeric closure and washer to the container;
whereby when said elastomeric closure is placed over the open top of the container, the flange of the elastomeric closure engages the upper surface of the rim of the container and the plug engages the open top of the container to seal the container with said crimping cap surrounding the elastomeric closure and the washer and engaging the upper surface of the washer and the bottom surface of the rim of the container.

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.
