Abstract: A dispensing closure (40) for a container (44) of a fluent substance is disclosed. The closure includes a body (54) having an inlet portion (68) defining an inlet flow passage (74) for receiving the fluent substance from the container (44) and an elongate outlet portion (70) defining an outlet flow passage (78) for discharging the fluent substance. The closure (40) further has a valve (56) located within the body (54), across the inlet flow passage (74) and spaced axially inwardly of outlet flow passage (78) to define a chamber (216). The valve (56) has a flexible, resilient valve head portion (160) that has confronting, openable portions (212) movable from a closed configuration to an open configuration when the valve head portion (160) is subjected to a pressure differential acting across the valve head portion (160).
