In one aspect, the invention is directed to a port assembly for establishing fluid communication between a first container and a second container. The port assembly includes a retainer for connecting a first container, where the retainer is positioned in a cavity defined by a port housing that includes an axially fixed actuator. The housing also includes a plug member constructed to seal a fluid passageway between the port housing and an interior of a second container. The plug member is configured to move axially relative to the actuator. Rotation of the retainer relative to the actuator causes the plug member to move to an open position in which it does not seal a fluid passageway between the port housing and an interior of a second container. The rotation of the retainer relative to the port housing also causes the retainer to move axially relative to the port housing so that the actuator forces a stopper associated with a first container connected to the retainer into a first container.

1. A port assembly for establishing fluid communication between a first container containing a first substance and a second container containing a second substance, the port assembly comprising: a retainer for connecting to a first container;a port housing for connecting to a second container, the p
1. A port assembly for establishing fluid communication between a first container containing a first substance and a second container containing a second substance, the port assembly comprising: a retainer for connecting to a first container;a port housing for connecting to a second container, the port housing defining a cavity, the retainer positioned at least partially within the cavity, the port housing comprising an axially fixed actuator constructed to force a stopper associated with a first container into a first container; anda seal to prevent fluid communication through a fluid passageway between the port housing and an interior of a second container,wherein the retainer is configured to rotate relative to the port housing, wherein rotation of the retainer relative to the port housing causes the retainer to move axially relative to the port housing such that the actuator forces a stopper associated with a first container connected to the retainer into a first container, and wherein rotation of the retainer relative to the port housing further causes the seal to open a fluid passageway between the port housing and an interior of a second container. 2. The port assembly of claim 1, wherein the seal comprises a plug member comprising at least one leg, wherein the retainer pushes the at least one leg to move the plug member to an open position as the retainer to moves axially relative to the port housing. 3. The port assembly of claim 1, wherein the seal is constructed to move at least partially into a second container upon rotation of the retainer relative to the port housing. 4. The port assembly of claim 1, wherein a first set of threads are formed on a surface of the port housing and wherein a second set of threads are formed on a surface of the retainer, the first and second set of threads constructed to rotationally engage and move the retainer axially into the port housing upon rotation of the retainer relative to the port housing. 5. The port assembly of claim 1, the port assembly further comprising a collar that is rotationally fixed to the retainer, wherein the collar comprises a first locking element and the retainer comprises a second locking element constructed to cooperate with the first locking element to prevent rotation of the collar and the retainer relative to the port housing if a first container is not connected to the retainer. 6. The port assembly of claim 5, 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. 7. The port assembly of claim 5, wherein the collar circumscribes the retainer, and the first locking element comprises a tab extending radially inwardly from the collar, and wherein the second locking element comprises a protrusion wherein the engagement between the tab and the protrusion prevents axial movement of the retainer relative to the collar. 8. The port assembly of claim 7, wherein the tab of the first locking element is configured to cooperate with an unlocking member associated with a first container such that connection of a first container to the retainer releases engagement between the tab and the protrusion of the second locking element. 9. The port assembly of claim 1, wherein the retainer comprises a retention tab configured to engage a first container to axially lock a first container to the retainer. 10. 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. 11. The port assembly of claim 10, wherein the seal member is constructed to sealingly engage a first container in a radial direction. 12. The port assembly of claim 11, wherein the seal member comprises a plurality of circumferential sealing surfaces to sealingly engage a first container in a radial direction. 13. The port assembly of claim 1, wherein the actuator comprises a tip portion that engages a stopper associated with 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. 14. The port assembly of claim 13, wherein the actuator comprises a plurality of support members that extend radially from a common axis. 15. The port assembly of claim 13, wherein the at least one support member is tapered as the member transitions to the tip portion. 16. A port assembly for establishing fluid communication between a first container containing a first substance and a second container containing a second substance, the port assembly comprising: a retainer for connecting to a first container;a port housing for connecting to a second container, the port housing defining a cavity, the retainer positioned at least partially within the cavity, the port housing comprising an actuator constructed to force a stopper associated with a first container into a first container; anda seal to prevent fluid communication between a first container and a second container,wherein the retainer is configured to rotate relative to the port housing, wherein rotation of the retainer relative to the port housing causes the retainer to move axially relative to the port housing, wherein axial movement of the of the retainer relative to the port housing places a first container and a second container in fluid communication by causing (i) the actuator to force a stopper associated with a first container connected to the retainer into a first container, and (ii) the seal to open. 17. The port assembly of claim 16, wherein the actuator is axially fixed within the cavity of the port assembly. 18. The port assembly of claim 16, wherein the seal is a plug member constructed to move axially relative to the port housing to an open position when the retainer moves axially relative to the port housing. 19. The port assembly of claim 16, wherein the seal is a septum or film. 20. A port assembly for establishing fluid communication between a first container containing a first substance and a second container containing a second substance, the port assembly comprising: a retainer for connecting to a first container;a port housing for connecting to a second container, the port housing defining a cavity, the retainer positioned at least partially within the cavity; andan actuator positioned at least partially within the cavity of the port housing, the actuator constructed to force a stopper associated with a first container into a first container;wherein the retainer is configured to rotate relative to the port housing, wherein rotation of the retainer relative to the port housing causes the retainer to move axially relative to the port housing, and wherein axial movement of the of the retainer relative to the port housing causes the actuator to force a stopper associated with a first container connected to the retainer into a first container.
