Abstract
A closure device for a container opening includes a lid element for closing the container opening, a chamber which is arranged on the lid element, and an inner housing. The chamber and the inner housing have corresponding closure means and opening means as well as corresponding first threaded means. A discharge opening paired with the chamber can be released with the aid of the threaded means by moving the lid element relative to the inner housing such that a medium stored in the chamber can exit into the container. The chamber has a first region above the first threaded means and a second region below the first region, wherein, relative to an axis of rotation of the thread, the first region is designed radially greater than the second region.
