A closure device (1) for a container (2) with a container opening (3) comprises a cover element (4) for closing the container opening (3), an internal housing (5), and a chamber (6) arranged on the cover element (4). The chamber is arranged at least partially in the internal housing (5) which has a first screw thread (10) corresponding in an interlocking way to a screw thread (10) of the container (2). The cover element (4) and the internal housing (5) have corresponding second screw threads (11), along which the cover element (4) can be moved relative to the internal housing (5) from a closed position into a discharge position, in which a medium stored in a chamber (6) in the container (2) can exit. The first and second screw threads (10/11) are designed to work in opposite directions, by which means the chamber (6) is moved further into the internal housing (5) during a movement into the discharge position. |
