Abstract
The present disclosure is directed to a drinking vessel that can include a drinking container and a drinking attachment that is coupled to the container. A straw can be positioned through an opening in the drinking attachment. The straw can include a top end that includes an opening through which a user can withdraw liquid and a bottom end. A drinking valve can be positioned along the bottom end of the straw and can include a tube that is open on the top and closed on the bottom and further includes at least one flow-through opening connecting the inside of the valve to the outside of the straw. A suction tube can include a tube wall that can be slid over the valve to couple the straw to the suction tube.
Claims18
A drinking vessel comprising:
- a drinking container comprising an interior,
- a drinking attachment comprising a bottom wall and a straw, which protrudes upwards from the bottom wall and which has at least one drinking opening on the outer end, which is connected to the interior of the drinking container via a passage channel, which extends through the straw,
- holding devices for releasably holding the drinking attachment on the drinking container,
- a drinking valve coupled to the straw, which closes when ambient pressure is present at the drinking opening, and which opens when a suction underpressure is present at the drinking opening,
- a suction tube disposed about a portion of the straw and drinking valve and comprising a tube wall,
- wherein the drinking valve comprises a tube, which is open on the top and closed on the bottom and a side wall comprising at least one flow-through opening, which connects an inside of the tube to an outside of the tube, wherein the side wall of the tube, at least in the area of the flow-through opening, is formed as an elastic diaphragm, and
- when ambient pressure is present at the drinking opening, the tube wall of the suction tube abuts with an outer rim of the flow-through opening so as to form a seal and, when a suction underpressure is present at the drinking opening, the diaphragm bulges inwards, so that the outer rim of the flow-through opening moves away from the tube wall of the suction tube.
