A dispensing valve for liquid containers of the type which is normally actuated by a resiliently flexible concave diaphragm to automatically close or self-seal it but which can be manually opened a toggle arrangement including an actuating lever or tab extension projecting outwardly from the concave diaphragm. In combination with this automatically-closing toggle-actuated diaphragm structure, an extended spout is provided for slidably mounting the valve so that during shipping or when the container is not to be used for dispensing during relatively long periods, the valve is in a retracted non-dispensing position where it will be provided with an additional seal and where the valve cannot be accidentally opened by engaging the toggle lever or by shock but can be extended readily to dispensing position when desired.

In combination, a valve assembly comprising an outer tubular valve unit having an orifice and adapted to be slidably mounted in a tubular spout or the like for sliding movement to cover or expose said orifice and an inner toggle-actuated self-closing valve unit mounted within said outer tubular valve unit and having a resiliently flexible sealing skirt which normally lies over and seals the orifice; said inner valve unit including toggle means which can be actuated to flex the sealing skirt away from the orifice to expose it for dispensing; and a tubular spout having an outer end, said outer tubular valve being telescoped within and slidably mounted in said spout for movement from a retracted position where the orifice is within the spout to an extended position where the orifice is beyond the outer open end of the spout.
