- 7. A lyophilization closure assembly for a medicament container having an open top and a rim surrounding said open top, comprising:
- a body secured about the open top of the container, the body having a distal wall disposed over the open top of the container and a skirt surrounding the rim of the container, a central passage provided on the distal wall, the skirt having a distal end, a proximal end, and one or more vapor passages formed therebetween, the body including one or more deflectable latches cooperable with the rim of the container and provided intermediate the distal and proximal ends of the skirt, the body having a first position, wherein the body is elevated from the open top of the container such that the vapor passages communicate with the open top, and a second position, wherein the deflectable latches lock the body to the rim and the vapor passages do not communicate with the open top of the container;
- an elastomeric closure secured within said body for sealing the open top of the container when the body is in the second position, the elastomeric closure having a plug for sealing the open top of the container, a flange portion retained against the distal wall of the body, and a top surface facing the central passage of the distal wall, the plug dimensioned to be spaced from the open top of the container when the body is in the first position such that the open top communicates with the vapor passages of the skirt;
- a washer secured in surface contact with the top surface of the closure, the washer defining an opening facing the central passage of the distal wall; and
- a membrane removably secured across the opening of the washer and hermetically enclosing the top surface of the closure.
- 8. The lyophilization closure assembly of claim 7, wherein the membrane is further removably secured across the central passage of the distal wall.
- 9. The lyophilization closure assembly of claim 7, further comprising one or more sealing ribs disposed between the flange portion of the elastomeric closure and the distal wall of the body.
- 10. The lyophilization closure assembly of claim 7, wherein the body includes a tubular extension surrounding the central passage of the distal wall and the elastomeric closure includes an upstanding projection securely retained within the tubular extension, the top surface of the closure provided on the upstanding projection.
- 11. The lyophilization closure assembly of claim 10 further comprising one or more sealing ribs disposed between the upstanding projection of the closure and the tubular extension of the body.
- 12. The lyophilization closure assembly of claim 7, wherein the elastomeric closure is formed of a rubber material and the washer is formed of a plastic material.
- 13. The lyophilization closure assembly of claim 12, wherein the elastomeric closure and the washer are formed together in a co-injection process.
- 14. The lyophilization closure assembly of claim 7, wherein the washer is formed of a plastic material and the membrane is formed of a foil material.
- 15. The lyophilization closure assembly of claim 14, wherein the washer and the membrane are formed together in a co-injection process.
- 16. The lyophilization closure assembly of claim 7, wherein the elastomeric closure is formed of a rubber material, the washer is formed of a plastic material, and the membrane is formed of a foil material.
- 17. The lyophilization closure assembly of claim 16, wherein the elastomeric closure, the washer, and the membrane are formed together in a co-injection process.
- 18. A lyophilization closure assembly for a medicament container having an open top and a rim surrounding said open top, comprising:
- a body secured about the open top of the container, the body having a distal wall disposed over the open top of the container and a skirt surrounding the rim of the container, a central passage provided on the distal wall, the skirt having a distal end, a proximal end, and one or more vapor passages formed therebetween, the body having one or more deflectable latches cooperable with the rim of the container and provided intermediate the distal and proximal ends of the skirt, the body having a first position, wherein the body is elevated from the open top of the container such that the vapor passages communicate with the open top, and a second position, wherein the deflectable latches lock the body to the rim and the vapor passages do not communicate with the open top of the container;
- an rubber closure secured within said body for sealing the open top of the container when the body is in the second position, the rubber closure having a plug for sealing the open top of the container, a flange portion retained against the distal wall of the body, and a top surface facing the central passage of the distal wall, the plug dimensioned to be spaced from the open top of the container when the body is in the first position such that the open top communicates with the vapor passages of the skirt;
- a plastic washer secured in surface contact with the top surface of the closure, the washer defining an opening facing the central passage of the distal wall; and
