Cap for a container, including a body having an inlet, a spout and a passageway therebetween. The cap also includes a valve movable between a first position wherein the passageway is blocked and a second position wherein the passageway is at least partly unblocked, the valve being biased towards the first position. Furthermore, the cap includes an actuator mounted to the body and engaging the valve. Selective control of the state of the valve is associated with movement of the actuator in a different direction than for securing the valve in the open position.
