Abstract A dispensing cap construction including a base cap attachable to a container, the base cap having a spout formation provided with a side wall and with a flow passage in the side wall, and a cover cap which is both turnably mounted on the base cap and axially movable theron between a lowered sealing position and a raised dispensing position. The cover cap has a discharge orifice, and a valving wall and dischage passage in the valving wall, both of which move circumferentially around the side wall of the spout formation. The valving wall moves into and out of a sealing position wherein it covers or uncovers the flow passage in the side wall of the base cap when the cover cap is turned. The valving wall has positions intermediate its full cover and full uncover positions wherein it only partially closes the flow passage. The discharge orifice of the cover cap is sealed at a point downstream of the flow passage of the base cap when the cover cap is in its lowered position thereon.
