A bottle teat comprising: A nipple sleeve having a hollow nipple and a through-hole connected at the bottom to a hollow nipple sleeve which is connected at the bottom to a nipple flange that is connected to the nipple sleeve to be fastened to a bottle by a fastening ring which serves at the bottom with an annular disc-shaped ring flange overlapping the nipple flange, A contact area projecting downward or upward from the nipple flange, or from the nipple sleeve above the nipple flange outward into the area for placing a ring flange, and A lip valve that is opened when the nipple flange is not fastened to a bottle arranged in a deforming area next to the contact area so that the deformation of the nipple flange that arises from pressing the fastening ring against the contact area closes the valve. |
