A reusable connector (20) is provided for mounting on an anaesthetic vaporizer to connect the vaporizer with an anaesthetic container (10) and hold the container (10) in an inverted orientation. Cooperating engaging structures are employed to pull the container (10) and connector (20) together. In a preferred form, the container (10) has a closure (30) definin g at least one port (42, 44) occluded by a recessed, pierceable membrane (46, 48). A screw thread (96) is provided on the container (10). The connector (20) has a base (50) provided with a first coupling (52) for connecting the base (50) to the vaporizer. The base (50) has a second coupling that include s plug (60) adapted to be connected to the container closure (30). The base (50) also defines a passage (71, 72) extending from the plug (60) through the first coupling (52) for communicating with the vaporizer. The plug (60) includes at least one projecting conduit (81, 82) that communicates with the passage (71, 72) and that defines a piercing tip for entering into the port to pierce the membrane (46, 48). A collar (90) is mounted for rotation on the base (50). The collar (90) engages the base (50) and defines a screw thread (92) for engaging the thread (96) on the container (10) to pull the containe r (10) onto the plug (60) as the membrane (46, 48)is pierced.
