  • Patent number: 5860541
    Abstract: A teat or nipple for the feeding of young animals. The teat is formed by a hollow body (10) made of a resilient material. The body has an inlet end (11) and an outlet end (12). The outlet end includes one or more slits (20) through the wall (19) of the body. The slit or slits (20) do not extend into that area (18) of the wall (19) of the body which forms the extremity (18) of the outlet end (12). A valve 26, 27) is located in the inlet end (11), said vale having a bore (30) with a pair of flaps (36) at the inner end of the bore, these flaps defining an outlet slot (38) through which liquid passing through one end of the bore can pass into the interior of the hollow body. The valve in its relaxed state is open to permit such flow to occur but the flaps are such as to close the outlet slot (38) upon any reverse flow of liquid from the interior of the hollow body occurring.
