1. A drinking container with a drinking vessel, a drinking cap and a threaded ring, wherein:
the drinking vessel has an inner space (13), a circular vessel opening (10), an opening edge (11) surrounding the vessel opening and an external thread (12) next to the vessel opening, the drinking cap (2; 41; 49; 64) has a bottom wall (15; 44; 53; 67), a ring flange (14; 42; 50; 65) surrounding the bottom wall for abutment on the opening edge of the drinking vessel, a drinking element (18; 46; 53; 77) protruding outwards from the bottom wall and a sealing means (27; 47; 48; 59; 4; 74; 77) for sealing and opening a passage from the inner space (13) to the outside of the mouthpiece, which is openable for drinking and otherwise closable, a ventilation channel (34; 43; 51; 66) is present in the bottom side of the ring flange (14; 42; 50; 65) or in the top side of the opening edge (11), which extends from an inner channel opening (40.1) lying further inside radially and open towards the inner space (13) of the drinking vessel (1) up to an outer channel opening (40.2) lying further outside radially and open to the environment, surrounds the center of the vessel opening (10) at least 0.75-fold between these two channel openings, has a cross-sectional surface in the range of 0.02 to 0.08 mm2 and is designed in a rigid material with a modulus of elasticity of at least 0.2 kN/mm2, and the ring flange (14; 42; 50; 65) is fixable in liquid-tight abutment on the opening edge (11) by means of the threaded ring. |
