The fluid dispensing apparatus includes a body portion supporting a pump assembly and a valve assembly. A fastening ring has an internal screw-thread for screw-threadedly engaging the neck of a container. A fastening ring retaining member allows the ring to rotate freely with respect to the body portion but also has a central opening for accommodating a fastening member which acts both to lock the member to the body portion and to couple with an outlet duct in the body portion leading to the valve assembly. In addition the member defines a separate passage which provides communication between the pump assembly and the interior of the container. The fastening member has a central opening for receiving a pipe which is arranged to extend to the bottom of the container.
