Abstract

A closure assembly has a closure cap (2) adapted to be fitted to the neck of container to close the container. The cap (2) has an upper wall (4) and a cylindrical skirt (5) depending therefrom. A reservoir (7) is formed on the underside of the upper wall (4) radially within the skirt (5) and has a dispensing opening (9). A closing member (3) is fitted into the closure cap (2) to close the dispensing opening in the reservoir. When the closure cap (2) is removed from the container, the closing member (3) remains held within the neck of the container and is separated from the closure cap so that the dispensing opening is opened and material contained therein is dispensed into the container. The closure cap is provided with sealing means for directly sealing against the neck of a container such as an annular wall (12) extendin downwardly from the underside of the upper wall of the closure cap (2) to fit sealingly into the neck of the container.
