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.

Abstract: A drinking vessel comprising a drinking container comprising an interior, a drinking attachment comprising a bottom wall and a drinking element, 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 via a passage channel, which extends through the drinking element, holding devices for releasably holding the drinking attachment on the drinking container, a drinking valve arranged in the passage channel, which closes when ambient pressure is present at the drinking opening, and which opens when a suction underpressure is present at the drinking opening, characterized in that the drinking valve comprises a tube, which is open on the top and closed on the bottom, which, in a wall, has at least one flow-through opening, which connects the inside of the tube to the outside of the tube, wherein the wall of the tube, at least in the area of the flow-through opening, is formed as a soft elastic diaphragm, and when ambient pressu

Abstract: A drinking container including a drinking vessel having an interior and vessel neck with a vessel opening, a drinking lid which has a bottom wall, at least one through-channel with an opening to the interior and an opening to the surroundings, a valve seat and holding devices for releasably holding the drinking lid on the drinking vessel, a valve element that is held on the valve seat and consists of soft elastic material and has a plate-shaped main body that blocks the through-channel, the main body having a passage which is open when the main body is in an undeformed state, and a clamping device with at least one clamping surface that is perpendicular to the plate-shaped main body and exerts a clamping force on the outer edge of the plate-shaped main body which closes the passage.

Abstract: A syringe with a syringe cylinder and a syringe, with a seat for the syringe cylinder and an axially displaceable piston seat for the syringe piston. There is an encoding on the syringe cylinder with encoding elements as protrusions and deepenings (depressions) at seven encoding positions, checking elements in the form of further protrusions and further deepenings at seven checking positions, each being disposed between two encoding positions. The encoding elements and the checking elements have six protrusions in total, and a guiding structure to align the syringe on a further guiding structure with each encoding element and with each checking element to a sensing element, said further guiding structure being disposed in the seat of the metering device and having a certain position with respect to an annular sensing device for sensing the encoding by sensing elements of the metering device that are across the circumference.

Abstract: A drinking container with a drinking vessel, a drinking cap and a threaded ring. The drinking vessel has an inner space, a circular vessel opening, an opening edge surrounding the vessel opening and an external thread next to the vessel opening. The drinking cap has a bottom wall, a ring flange surrounding the bottom wall for abutment on the opening edge of the drinking vessel, a drinking element protruding outwards from the bottom wall and a valve for sealing and opening a passage from the inner space to the outside of the mouthpiece, which is openable for drinking and otherwise closable. A ventilation channel is present in the bottom side of the ring flange or in the top side of the opening edge.
