A one piece self closing dispensing valve (1) of molded polymer material is used in combination with a beverage container. The valve is of the kind containing a movable actuator (5) which in response to a force applied thereto by a user, such as pressure exerted by the users finger, opens the valve to dispense liquid under force of gravity. A leaf spring (4) operable over the range of actuator movement and normally biasing the actuator responds to the withdrawal of the applied force to return the actuator to its normal position and thereby close the valve. An integral dripless spout is defined between the actuator and the valve body; the effective size of which is inversly dependent on the position of the actuator. |
