System and method for mixing the contents of two containers

摘要

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.
