Abstract: A teat for feeding liquids to animals has a fastening member enabling the teat to be fastened to a source of liquid such as pipe or drum in use to project outwardly from the source. The teat is resilient having an outer end which is closed apart from a slit in it which slit is itself normally adapted to be closed to provide a liquid seal. The closed outer end is preferably concave, coned, cusped or otherwise reentrant. Integral reinforcing members such as webs are located internally on either side of the slit so that if the end of the teat is squashed or compressed by sucking forces exerted by the animal with components along the direction of slit, the reinforcing member causes the slit to be stretched open, thereby allowing liquid to flow out of it in use. The pulling or stretching action allows an acceptable flow rate from a comparatively small slit which is less prone to tear than a large slit.

Abstract: A teat for feeding liquids to animals adapted to be fastened to a source of liquid such as a pipe or drum in use to project outwardly from the source. The teat has a resilient outer end which is closed apart from a slit in it which slit is itself normally adapted to be closed by the resilience to provide a sufficient liquid seal. The closed outer end is preferably concave, coned, cusped or otherwise re-entrant. A reinforcing member such as webs are located, preferably internally on either side of the slit so that if the end of the teat is squashed or compressed by sucking forces exerted by the animal, with components along the direction of slit, the reinforcing member causes the slit to be pulled open, thereby allowing liquid to flow out of it in use. The pulling action allows an acceptable flow rate from a comparatively small slit which is less prone to leak than a large slit.
