Abstract
A closure device which includes a fluid chamber containing an additive such as a liquid and a housing having a plug member. The cap member is provided with a primary engagement means, such as an internal thread, which engages with a corresponding primary engagement means provided on the housing, such as an external thread, to allow the cap member to be lifted relative to the housing from a closed position in which the plug member closes a bottom aperture and a spout aperture in the fluid chamber, through a first open position in which the plug member is at least partially withdrawn from the bottom aperture while still closing the spout aperture, thereby allowing the additive to pass from the fluid chamber, and to a second open position in which the spout aperture is at least partially open.
