Abstract
A closure device which includes a fluid chamber containing an additive such as a liquid which can be introduced and mixed into a liquid in a container by operation of the closure device. The closure device includes a cap member having a fluid chamber and a housing having a plug member. The cap member may have a cam or follower surface on a lower surface of the cap top wall, which engages with a corresponding cam or follower surface on an upper surface of the housing, to allow the cap member to be lifted relative to the housing from a closed position in which the plug member closes an aperture in the fluid chamber to an open position in which the plug member is at least partially withdrawn from the aperture, thereby allowing the additive to pass from the fluid chamber to the liquid in the bottle.
