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) defining 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 includes 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 container (10) onto the plug (60) as the membrane (46, 48) is pierced.

Raccord réutilisable (20) se montant sur un vaporisateur d'anesthésique qu'il relie au récipient (10) contenant l'anesthésique tout en maintenant ce dernier (10) à l'envers. Le récipient (10) et le raccord (20) sont maintenus ensemble par plusieurs structures à emboîtement. Dans sa forme préférée, le récipient (10) est muni d'une fermeture (30) comportant au moins un orifice (42, 44) clos par une membrane évidée perçable (46, 48). Le récipient (10) est muni d'un pas de vis (96) et le raccord (20) est pourvu d'une base (50) munie d'un premier accouplement (52) qui la fixe au vaporisateur. Ladite base (50) est munie d'un second accouplement comportant une fiche (60) conçue pour être raccordée à la fermeture (30) du récipient. La base (50) comporte en outre un passage (71, 72) reliant la fiche (60) au vaporisateur via le premier accouplement (52). La fiche (60) comporte au moins un tube saillant (81, 82) communiquant avec le passage (71, 72) et qui présente une extrémité de percement qui pénètre dans l'orifice pour percer la membrane (46,48). Un collier (90), monté tournant sur la base (50), et qui s'emboîte sur elle, comporte un filetage (92) qui s'engage dans celui (96) du récipient (10) pour amener le récipient (10) sur la fiche (60) lors du percement de la membrane (46,48).
