Abstract
A teat unit for sucking a liquid from a liquid container includes a teat and a flow restrictor with a through-opening. The teat comprises a mouthpiece, with a suction opening, and a main body which is formed integrally on the mouthpiece and widens relative to the mouthpiece. The flow restrictor defines a maximum flow of the liquid passing through the suction opening from the liquid container. According to the invention, the flow restrictor is arranged outside the mouthpiece, and the suction opening has a greater cross-sectional surface area than the through-opening of the flow restrictor. The teat unit permits a feeding action that is as true to nature as possible, since the mouthpiece can be deformed very considerably, without substantially impairing the flow restriction.
