Abstract: An apparatus may include an insert configured to be positioned between a nipple and an opening of a bottle when the nipple is mounted to the bottle. The insert is configured to facilitate airflow out of the bottle and through an interface between the nipple and the bottle when the nipple is dispensing fluid from within the bottle. A system may include a nipple, the insert, and a bottle with an opening. A method may include providing the insert, and positioning the insert between a nipple and an opening of a bottle when the nipple is mounted to the bottle.

Abstract: A drinking attachment (10) for drinking vessels (12), comprising a funnel-like circumferential drinking rim (14), which is open towards the drinking vessel (12), having a fastening section (16) for fastening the drinking attachment (10) to an edge region of the drinking vessel surrounding an opening of the drinking vessel (12), and a bowl-shaped elastic sealing disc (20), which can be inserted into the drinking rim (14) for sealing the drinking rim (14), the sealing disc (20) abutting circumferentially against the drinking rim (14) in the region of the end of the drinking rim (19, which is free in the intended mounting state of the drinking attachment (10) on a drinking vessel (12), while forming an interstice (22), which is open towards the drinking vessel (12), and being designed in such a way that it can be partially lifted from the drinking rim (14) by a suction action of a user of the drinking attachment (10), in order to open a passage to the interstice (22), the sealing disc (20) having in the region o

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 teat with a base and a hollow and flexible mouthpiece protruding from it with a palate contact area, characterized in that the mouthpiece has a planar thinning area fully or partially extending over the palate contact area, in which the mouthpiece has a smaller wall thickness than in its adjacent areas.

Abstract: A teat, in particular for infants and small children, having a hollow nipple with at least one through-hole for liquid nutrition, which is connected at the bottom to a substantially annular-disc-shaped nipple flange, which serves to be fastened to the mouth of a vessel by means of a fastening ring with an annular-disc-shaped ring flange overlapping the nipple flange for pressing the bottom side of the nipple flange flat against the front-side edge of the mouth and at least one recess extending in the radial direction of the nipple flange on the top side of the nipple flange so that a ring flange of a fastening ring pressing against the top side of the nipple flange is spaced from the top side of the floor of the recess during the fastening of the teat on the mouth of a vessel, and the nipple flange is sufficiently flexible at least in the area of the recess so that the floor arches up and air from outside flows back into the vessel under the arched floor of the recess in the radial direction when the teat is
