摘要

The rubber sleeve (2) for a teat cup in a milking machine has a sealing collar (20) at the top with an inwardly-facing sealing lip (22) which fits against the teat. If a narrower teat is introduced into the sleeve and the lip does not initially contact it, the collar bends inwards until the lip contacts it.
