The suction teat unit for sucking a liquid from a liquid container, comprises a suction teat (4) and a flow limiter with a through opening (32). The suction teat (4) comprises a mouth piece (42) with a suction opening (43) and a base body (40) moulded on the mouth piece (42) tapering outwards relative to the mouth piece (42). The flow limiter determines a maximum flow of the liquid from the liquid container flowing through suction opening (43). According to the invention, the flow limiter is arranged outside the mouth piece (42) and the suction opening (43) has a larger cross-sectional area than the through opening (32) of the flow limiter. The suction teat unit permits a sucking which is as natural as possible, wherein the mouth piece (42) can be largely deformed without substantially affecting the through flow limitation.
