A port assembly for establishing fluid communication between a first container and a second container. The port assembly includes a port housing for connection to a second container, and a retainer for connection to a first container, wherein the retainer rotates relative to the port housing and is constructed to move axially within the port housing. An actuator is axially fixed within the port housing and forces a stopper associated with a first container into a first container when the retainer moves axially within the port housing upon rotation of the retainer relative to the port housing. The assembly is configured to establish fluid communication between a first container and a second container upon rotation of the retainer relative to the port housing.

1. A port assembly for establishing fluid communication between a first container and a second container, the port assembly comprising: a port housing constructed for connection to a second container, the port housing having a first end and a second end, the post housing defining a cavity;a retainer
1. A port assembly for establishing fluid communication between a first container and a second container, the port assembly comprising: a port housing constructed for connection to a second container, the port housing having a first end and a second end, the post housing defining a cavity;a retainer constructed for connection to a first container, wherein the retainer rotates relative to the port housing, the retainer constructed to move axially within the cavity of the port housing toward the second end of the port housing upon rotation of the retainer relative to the port housing;an actuator within the cavity of the port housing, the actuator constructed to force a stopper associated with a first container into a first container when the retainer moves axially within the port housing upon rotation of the retainer relative to the port housing; anda locking mechanism that prevents rotation of the retainer relative to the port housing if a first container is not connected to the retainer. 2. The port assembly of claim 1, wherein the port assembly is configured to establish fluid communication between a first container and a second container upon rotation of the retainer relative to the port housing. 3. The port assembly of claim 1, wherein the port housing comprises first threads and the retainer comprises second complementary threads, the first and second threads being constructed to cause the retainer to move axially within the port housing toward the second end of the port housing upon rotation of the retainer relative to the port housing. 4. The port assembly of claim 1, wherein the retainer comprises a seal member constructed to sealingly engage a first container when a first container is connected to the retainer. 5. The port assembly of claim 4, wherein the seal member is constructed to sealingly engage a first container in a radial direction. 6. The port assembly of claim 5, wherein the seal member includes a plurality of circumferential sealing surfaces to sealingly engage a first container in a radial direction. 7. The port assembly of claim 1, further comprising a collar that is rotationally fixed to the retainer and rotatably connected to the port housing. 8. The port assembly of claim 7, wherein the locking mechanism comprises a first locking element on the collar and a second locking element on the retainer, wherein the first locking element and the second locking element cooperate to prevent rotation of the collar and the retainer relative to the port housing if a first container is not connected to the retainer. 9. The port assembly of claim 8, wherein the first locking element and the second locking element cooperate to prevent axial movement of the retainer relative to the collar if a first container is not connected to the retainer. 10. The port assembly of claim 9, wherein the collar circumscribes the retainer, the first locking element comprises a tab extending radially inwardly from the collar, the second locking element comprises a protrusion, and wherein the tab of the first locking element is constructed to engage the protrusion of the second locking element to prevent axial movement of the retainer relative to the collar. 11. The port assembly of claim 10, wherein the tab of the first locking element is configured to cooperate with an unlocking member on a first container whereby connection of a first container to the retainer releases engagement between the tab and the protrusion of the second locking element. 12. The port assembly of claim 1, wherein the retainer comprises at least one radially extending retention tab configured to engage a first container to axially lock a first container to the retainer. 13. The port assembly of claim 1, wherein the actuator is axially fixed within the cavity of the port housing. 14. The port assembly of claim 13, wherein the actuator comprises a tip portion constructed to force a stopper associated with a first container into a first container, and wherein the actuator further comprises at least one support member mounted on the port housing, the at least one support member positioned between the port housing and the tip portion. 15. The port assembly of claim 14, wherein the at least one support member is tapered as it transitions to the tip portion. 16. The port assembly of claim 1, further comprising a seal at the second end of the port housing to prevent fluid communication between a first container and a second container, wherein the seal is opened upon rotation of the retainer relative to the port housing. 17. A port assembly for establishing fluid communication between a first container and a second container, the port assembly comprising: a port housing constructed for connection to a second container, the port housing having a first end and a second end, the port housing defining a cavity;a retainer constructed for connection to a first container, wherein the retainer rotates relative to the port housing, and wherein rotation of the retainer relative to the port housing causes the retainer to move axially within the cavity of the port housing toward the second end of the port housing and places the first container and the second container in fluid communication;an actuator within the cavity of the port housing, the actuator constructed to force a stopper associated with a first container into a first container when the retainer moves axially within the port housing upon rotation of the retainer relative to the port housing;a collar rotationally fixed to the retainer, wherein rotation of the collar translates into rotation of the retainer; anda locking mechanism that prevents rotation of the retainer relative to the port housing if a first container is not connected to the retainer. 18. The port assembly of claim 17, further comprising a seal at the second end of the port housing to prevent fluid communication between a first container and a second container, wherein the seal is opened upon rotation of the retainer relative to the port housing. 19. The port assembly of claim 17, wherein the locking mechanism comprises a first locking element on the collar and a second locking element on the retainer, wherein the first locking element and the second locking element engage each other to prevent rotation of the retainer relative to the port housing if a first container is not connected to the retainer. 20. The port assembly of claim 19, wherein connection of a first container to the retainer releases engagement between the first locking element and the second locking element, thereby allowing rotation of the retainer relative to the port housing.
