<p>The variable feed rate nipple (1) of the invention, adapted to a feeding bottle and comprising at the end of its teat (2) a slot (3) having two branches (3a, 3b) forming between each other an angle, is characterized in that the angle formed by the two branches of the slots (3) is an obtuse angle Η comprised between 165° and 95°, of which the summit is on the axis of the nipple, in that the branches of the slot have lengthes l1 and l2 (with l1 > l2), such that the ratio l1/l2 is comprised between 1 and δ, the value of δ growing from 1 to 10, preferably from 1 to 4.5 when the value of the angle Η decreases from 165 to 95°, said branches of the slot (3) being formed by cutting lines without removal of material and opening at their non adjacent extremities into a small cross-section hole (4b, 4c).</p> |
