The teat unit for sucking a liquid from a liquid container comprises a teat (4) and a flow restrictor with a through-opening (32). The teat (4) comprises a mouthpiece (42), with a suction opening (43), and a main body (40) which is formed integrally on the mouthpiece (42) and widens relative to the mouthpiece (42). The flow restrictor defines a maximum flow of the liquid passing through the suction opening (43) from liquid container. According to the invention, the flow restrictor is arranged outside the mouthpiece (42), and the suction opening (43) has a greater cross-sectional surface area than the through-opening (32) of the flow restrictor. The teat unit permits a feeding action that is as true to nature as possible, since the mouthpiece (42) can be deformed very considerably, without substantially impairing the flow restriction.用於從液體容器中吸吮液體之奶嘴單元，其包含一奶嘴(4)和一具有一穿通開口(32)之限流器。該奶嘴(4)包含一具有吸入開口(43)之吸嘴(42)，以及一整體成形於該吸嘴(42)上和相對於該吸嘴(42)加寬的主體(40)。該限流器界定出自該液體容器流經該吸入開口(43)的最大液體流量。依照本發明，該限流器被配置於該吸嘴(42)之外部，且該吸入開口(43)具有一比該限流器之穿通開口(32)還要更大的截面表面區域。由於該吸嘴(42)可以產生相當的變形量，不致於影響到流量之限制狀況，該奶嘴單元容許得到儘可能是自然的餵給動作。
