Container closure assembly

摘要

A closure assembly has a closure cap adapted to be fitted to the neck of a container to close the container. The cap has an upper wall and a cylindrical skirt depending from the upper wall. A reservoir is formed on the underside of the upper wall radially within the skirt and has a dispensing opening. A sealing member is fitted into the closure cap to close the dispensing opening in the reservoir. When the assembly is fitted to the container the sealing member fits into the neck of the container with an interference fit such that when the closure cap is removed from the container, the sealing member 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.
