<p>A drinking system with a channel (1) for passing liquid from a container (6) to a user's mouth with a check valve (2) for passing liquid exclusively in a specific direction of flow. The check valve is located near the downstream end of the channel viewed in the direction of flow. Undesired flow-out of liquid from the end of the channel to be held in the mouth is reliably prevented, even in the case of changes in the volume of the channel or the liquid contained therein, as well as in an approximately horizontal position of the section of the channel adjacent the end of the channel to be held in the mouth. Further, contamination and fouling of the channel, the container and the potable liquid is prevented in that the channel is closed at the downstream end when no drinking is taking place. Further described is a mouthpiece (19) adapted for use in a drinking system according to the invention.</p> |
