Abstract
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.
