NIPPLE FOR A BABY BOTTLE

摘要

A nipple for a baby bottle includes both inner (110) and outer (112) separable members. The inner member defines a valve passage (216) that can be selectively obstructed by a flap (210) of the outer member. The outer and inner members have respective flexible membranes that define a holding chamber (218) having the valve passage as an inlet and an aperture (204) at the tip of the outer member as an outlet. The flap inhibits flow from the holding chamber through the valve passage when the outer member is compressed, and deflects away from the valve passage to allow the holding chamber to receive a fluid through the valve passage when the outer member is released.
