Claim:
A bottle teat in particular for infants and small children comprising: a nipple sleeve having a hollow nipple ( 4 ) with at least one through-hole ( 10 ) for liquid nutrition that is connected at the bottom to a hollow nipple sleeve ( 2 ) which is connected at the bottom to a substantially annular disc-shaped nipple flange ( 12 ) that is connected to the nipple sleeve ( 2 ) to be fastened to a fastening edge ( 29 ) of a bottle ( 22 ) by means of a fastening ring ( 23 ) which serves at the bottom with an annular disc-shaped ring flange ( 26 ) overlapping the nipple flange ( 12 ), a contact area ( 13 , 31 ) projecting outward from the nipple sleeve ( 2 ) above the nipple flange ( 12 ) into the area for placing the ring flange ( 26 ), a lip valve ( 15 ) that is open when the nipple flange ( 12 ) is not fastened to said bottle ( 22 ) and is arranged in a deforming area next to the contact area ( 13 , 31 ) so that, when the nipple flange ( 12 ) is attached to said bottle ( 22 ) by means of said fastening ring ( 23 ), the deformation of the nipple flange ( 12 ) caused by the pressure of the fastening ring ( 23 ) against the contact area ( 13 , 31 ) closes the lip valve ( 15 ), and wherein the contact area ( 13 ) is a bulge of the undeformed nipple flange ( 12 ) in which the lip valve ( 15 ) is arranged that is pressed flat between the fastening edge ( 29 ) and the ring flange ( 26 ) when the nipple flange ( 12 ) is attached to the bottle ( 22 ) by means of a fastening ring ( 23 ).
