<p>A valve (10,25) for fitting in the top of a liquid container for use in the extraction of liquid therefrom comprises a generally cylindrical main body part (11,26) having a base (12,27) snap-fitted in the lower end thereof, with an extraction pipe (14,29) extending integrally from the base for liquid flow therethrough into the main body part. A sealing member (17,35:37) is spring biased normally to close an upper opening (34) of the main body part, and prevent outflow between the pipe (14,29) and said upper opening, the sealing member being movable however by an actuator (40) to open said upper opening (34) and to allow flow through the valve.</p> |
