The invention relates a closure device (1) for a container opening (3), comprising a lid element (4) for closing the container opening (3), a chamber (6) which is arranged on the lid element (4), and an inner housing (5). The chamber (6) and the inner housing (5) have corresponding closure means (7) and opening means (9) as well as corresponding first threaded means (10). A discharge opening (8) paired with the chamber (6) can be released with the aid of the threaded means by moving the lid element (4) relative to the inner housing (5) such that a medium stored in the chamber (6) can exit into the container (2). The chamber (6) has a first region (A) above the first threaded means (10) and a second region (B) below the first region (A), wherein, relative to a axis of rotation of the thread (18), the first region (A) is designed radially greater than the second region (B). |
