The invention relates to a bottle-feeding device which comprises a nipple (2), extending along an axis and comprising a skirt (7) ending in a base opening (8) in order to form a recess (9) inside said skirt (7), and a ring (3) for coupling the nipple with a container (4). At least one intake through-opening (10) is formed in the skirt (7), the nipple (2) being designed to change, when the recess is pressed, from a sealed configuration in which the coupling ring is in contact with the intake opening in order to seal the latter, to an intake configuration in which the intake opening is separated from said coupling ring, in a substantially centripetal direction relative to the axis, in order to allow outside air to enter the recess via the intake opening, the nipple being designed to return resiliently to the sealed configuration in the absence of said pressing.
