  • Patent number: 10835065
    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.

  • Patent number: 9291529
    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.
