A stopper member (20) is fixed to the threaded collar (8) for selectively connecting the closure (1) to an anaesthetic transfer device. A discharge passage (23) and a venting passage (24) extend through the stopper member (20) for communication with a container (3) engaged by the threaded collar (8). A first pierceable diaphragm (25) is located within and occludes the discharge passage (23), and second pierceable diaphragm (29) is located within and occludes the venting passage (24).</p> |
