Abstract
The nipple (1) affixed to a bottle of a nursing infant (2) by means of ring (3) comprises a semi-rigid internal membrane (5) which limits the chamber reservoir (11). Said reservoir extends by means of a lactiferous duct which ends in an opening (9) normally closed by zone (8) of the thin elastic membrane (7) which covers internal membrane (5). During suction, zone (8) of the membrane (7) swells as it becomes filled with liquid from the lactiferous duct, expelling of the liquid into the mouth being then obtained by pinching of teat (8) between the lips, and the ejection of the liquid through opening (10) which then is uncovered.
