ABSTRACT:
A dispensing system is provided for dispensing liquid from a container. The system includes a discharge conduit defining a flow passage for establishing fluid communication with liquid from the container. A resilient valve is provided to extend across the discharge flow passage in an initial, substantially non-deformed, closed configuration. The valve has an interior side for being contacted by the liquid and an exterior side exposed to ambient external atmosphere. The valve defines a normally closed dispensing orifice that is displaceable outwardly to an open configuration when the pressure on the valve interior side exceeds the pressure on the valve exterior side by a predetermined amount, and is displaceable inwardly to an open configuration when the pressure on the valve exterior side exceeds the pressure on the valve interior side by a predetermined amount. A restraint structure is disposed in the discharge conduit in contact with the valve interior side when the valve is in the initial, substantially non-deformed, closed configuration. The restraint structure and the discharge conduit together define at least one flow path accommodating flow of the liquid from the container against at least a portion of the valve interior side. The restraint structure prevents the closed dispensing orifice from opening inwardly when the ambient external pressure on the valve exterior side exceeds the pressure on the valve interior side.
