<p>A resealable assembly for a container such as a bottle or vial (10) featuring a membrane (40) for selectively opening or sealing a fluid path between the bottle (10) and a medical delivery device (60) introduced into the assembly. The assembly includes a body (22) disposed on said bottle (10) and a luer connector hub (32) which may be separately provided with the body (22) or formed integrally therewith. The luer connector hub (32) features a connector end (34) open for access by the medical delivery device, and an opposed end (36) which is disposed for fluid communication with the open top of the bottle (10). A membrane (40), preferably formed from an elastomeric material, is secured across both the opposed end (36) of the luer connector hub (32) and the open top of the bottle (10) and may be retained between the top surface of the bottle (10) and the body (22). The membrane (40) preferably includes a central area (42) sealing the opposed end (36) of the luer connector hub (32) from the open top of the bottle (10) with one or more fluid openings (44) defined on a portion of the membrane (40) outside of the central area (42). A force exerted on the central area (42) by the medical delivery device (60) deflects the membrane (40) towards the interior of the vial (10), urging the membrane (40) from sealing contact with the body (10) and, hence, opening the fluid path between the interior of the bottle (10) and the medical delivery device (60). The central area (42) may display one or more fluid flow channels to facilitate fluid flow between the medical delivery device (60) and the bottle (10) as contact is made between the medical delivery device (60) and the central area (42) of the membrane (40). A sealing rib may be provided around a portion of the periphery of the luer connector hub (32) to enhance sealing contact between the membrane (40) and the luer connector hub (32). <IMAGE></p> |
