Abstract:
A closure for use in relation to a beverage container, the closure comprising sealing means for sealingly engaging the container, an integral chamber formed within or as part of the closure for sealingly containing a fluid for mixture with the beverage, and a release means for releasing the fluid from the chamber to the attached container, wherein the sealing means enables the closure to be repeatedly and sealingly attached to and removed from the container without essentially operating the release means, wherein the release means includes one or more apertures or ports in a wall of the chamber, the one or more apertures or ports being associated with a valve that is resealable on the aperture after having been opened such that when the closure is engaged with the container and the valve is open the fluid in the chamber may physically communicate with the beverage and when the valve is closed the fluid is retained in the chamber, and wherein the valve is operable to an open position only when the closure is attached to the container and is necessarily returned to a closed position upon or prior to being removed from the container.
