Abstract
A dispensing closure is provided with a body having an outlet passage. A sleeve is mounted on the body for rotation relative to the body. The sleeve has a transverse deck defining a discharge passage for communicating with the body outlet passage as the discharge passage moves in an arc relative to the body. In one embodiment, a seal is provided between the sleeve deck and the body around the outlet passage and discharge passage. In a preferred embodiment, an actuator is mounted on the sleeve for rotation with the sleeve. Engaging structures are defined by the body and actuator for tilting actuator between a closed position and an open position while the actuator is rotated with the sleeve. The actuator includes engaging portions for engagement with drive members projecting upwardly from the body through openings in the sleeve. Engagement between the drive members and actuator is effected on opposite sides of the pivot axis of the actuator so as to effect tilting of the actuator between an open position and a closed position.
