Abstract
A cover device () for a drink container having an improved leak resistance comprises a basic assembly () which is provided with a drink opening () and a ring-shaped member (), and a valve arrangement () for blocking or unblocking a passage to the drink opening () from a drink container side of the cover device (). The valve arrangement () comprises a valve element () having a sleeve () with a slit (), a circumference of the sleeve () being substantially similar to a circumference of the ring-shaped member (). The leak resistance of the valve arrangement is further improved in that the sleeve () and the ring-shaped member () have a first diameter in the direction of the slit () and a second diameter perpendicular to the slit (), wherein a ratio between the first and second diameters of the sleeve () is smaller than a ratio between the first and second diameters of the ring-shaped member ().
