2139868 9401026 PCTABS00030 A drinking mug, especially for small children, handicapped and hospital patients, comprising a cup (1), a lid (3) and a suction tube (5), is configured in an airtight manner so that the only access to the inside of the mug is through the suction tube (5). Tightness is achieved by disposing the suction tube (5) on the inside of the lid (3) on a drinking spout (15), and by providing a sealing ring (29) in the joint between the lid (3) and the cup (1). Due to the airtight construction, when liquid is sucked up an underpressure is created inside the mug which subsequently empties the suction tube of liquid. Correspondingly, an attempt by the liquid to run out through the suction tube (5) when the mug is tipped over is counteracted by the siphon effect which results from the airtight construction.
