A cover device (2) for a drink container comprises a basic assembly (9) which is provided with a drink opening (32), and a valve arrangement (20) for blocking or unblocking a passage to the drink opening (32) from a drink container side of the cover device (2). The valve arrangement (20) comprises a valve element (26) having two portions (27, 28) which are connected to each other through an area of the valve element (26) at a position where the valve element (26) is hingably associated with the basic assembly (9), the valve element (26) has a slit (42), and at least one of the valve element (26) and the connecting member (37) is shaped in such a way that the tighter the valve element (26) is pushed onto the connecting member (37), the more firmly the slit (42) is closed.

1. A cover device for a drink container, the cover device comprising: a basic assembly including a housing and a spout which comprises at least one drink opening; anda valve arrangement adapted to prevent liquid from flowing from an interior of the drink container to outside of the drink container through the cover device in a closed state and to allow a flow of liquid to pass through in an open state,the valve arrangement comprising a valve element, and a ring-shaped connecting member,wherein the valve element has a slit, and wherein the valve element is arranged at the base of the spout such that such that the ring-shaped connecting member contacts the valve element to realize a hinge contact between the valve element and the ring-shaped connecting member to allow for changes in the position and orientation of the valve element in the cover device when pressure is exerted,wherein the basic assembly has a connecting member for locally supporting the valve element at a position between an inner periphery and an outer periphery of the valve element, and wherein at least one of the valve element and the connecting member is shaped in such a way that the tighter the valve element is pushed onto the connecting member when an increased pressure acts on the valve element in a direction of the drink opening, the more firmly the slit is closed. 2. The cover device according to claim 1, wherein the valve element has a slanted shape at a location of the connecting member, wherein the slanted shape at least partially extends beyond a part of the valve element that overlaps with the connecting member in a rest position. 3. The cover device according to claim 2, wherein the valve element has more than one strengthening ribs that provide the valve element with the slanted shape. 4. The cover device according to claim 3, wherein the strengthening ribs are rotational symmetrically arranged around a center of the valve element. 5. The cover device according to claim 1, wherein the connecting member has a slanted slope that at least partially extends beyond a part of the connecting member that overlaps with the valve element in a rest position. 6. An assembly of a drink container and a cover device according to claim 1, wherein the cover device is removably attached to the drink container.
