This can be achieved, for example, by a special arrangement of the valve in the cover part.

  • At least one passage opening is provided in the passage in the area of the suction opening. The passage opening is designed in such a way that liquid in the area between the outlet valve and suction opening with the suction opening directed downward can be kept essentially within the passage due to a surface tension effect and / or capillary effect acting against the action of gravity.
  • This aspect of the invention is based on the knowledge that the liquid which escapes onto the outside of the drinking cup in the known leak-proof drinking cups comes from the liquid column between the outlet valve and the suction opening. This liquid remains there after liquid has been removed from the drinking cup after the outlet valve has closed.
  • surface tension effect means a physical effect which occurs in the case of liquid which is held under the action of air pressure in a vessel which is only open at the bottom.
  • capillary effect means a physical effect that occurs at points where three phases touch, in the present case liquid, ambient air and the material of the passage opening. This effect is referred to as “wetting", the free surface of the liquid in the vicinity of the solid surface of the passage opening having a curvature which is referred to as the "meniscus". If the solid surface has hydrophilic properties, a concave meniscus is formed, in which the liquid wets the wall of the passage opening.
  • hydrophilic character of a substance here the material of the passage opening or its surface, is understood to mean its tendency to penetrate and remain in water.
  • Hydrophilic compounds can have surfactants such as surfactants.
  • Typical hydrophilic groups are carboxylate, sulfate and sulfonate functions or polyether chains or carbonates, silicates, sulfates and quartz.
  • the curvature of the surface layer of the meniscus leads to the occurrence of an additional pressure in the liquid, which depends on the surface tension and the surface curvature of the liquid. This creates a negative pressure when the meniscus is concave. If the suction opening in the valve cover according to the invention is directed downward, this negative pressure counteracts the pressure of the liquid column inside the passage opening, so that it is drawn into the suction opening. Leakage of the liquid in the passage from the suction opening is effectively reduced or completely prevented when the suction opening is directed downward.
  • the use of suitable materials and the suitable design of the diameter, at least at the passage opening can ensure that the capillary effect inside the passage opening
  • the negative pressure is equal to or less than the pressure that can be generated by the liquid standing in the passage opening.
  • passage openings are provided. This ensures, even with very small diameters of the passage openings, that a sufficiently large volume flow can pass through the passage, especially if the passage openings are arranged next to one another.
  • passage openings are each separated from one another by at least one wall, the
  • Walls can also be arranged along the diameter of the passage if it has a substantially cylindrical shape. This ensures a particularly simple manufacture of the valve cover.
  • the effective diameter of the suction opening is made narrower than the effective diameter of the passage and / or the passage openings.
  • Such a configuration of the diameter of the suction opening can produce an additional capillary effect between the suction opening and the passage, which improves the effect of the valve cover according to the invention.
  • effective diameter it is meant that there is a connection between the diameter of the suction opening and the effect of the capillary effect, which can be determined in particular by experiment.
  • the effective diameter should be larger at those points of the passage where no capillary effect is desired than at those points where a capillary effect is desired.
  • the passage opening can have various shapes, each of which produces a desired capillary effect in connection with the configuration of the passage opening.
