  • Patent number: 4903870
    Abstract: A dispensing closure characterized by a cap base member adapted to be associated with a container, and a cap lid member mounted on the cap base member for rotation with respect to the cap base member. The cap lid member is adapted to assume a closed position, wherein it closes off a first dispensing opening formed in the cap base member, and is intended to be rotated upwardly with respect to the cap base member from the closed position to an open position wherein the first dispensing is uncovered. A second dispensing opening is formed in the cap lid member, overlying the first dispensing opening when the cap lid member is in the closed position. The second dispensing opening is normally closed off and sealed by means of a spout member which is rotatably mounted on the cap lid member. The spout member is adapted to be rotated from the latter closed position to an open position wherein a longitudinal passage in the spout member is aligned with the second dispensing opening.
