Abstract
A teatcup liner (,) which is intended for being mounted in a teatcup shell (,) comprises a tubular head portion (,) forming a passage for receiving a teat. The passage extends between a first and a second axial end of the tubular head portion. The tubular head portion has an annular lip (,), which in the mounted as well as the non-mounted state of the teatcup liner (,) extends radially inwardly from the tubular head portion. Furthermore, the teatcup liner comprises a tubular shaft portion (,), which extends from a second axial end (,) of the head portion, and a member (,), which is arranged to provide a radially outwardly directed pretension in the lip in the mounted as well as the non-mounted state of the teatcup liner (,), and is located outside said passage. A method of manufacturing such a teatcup liner comprises the steps of moulding the teatcup liner, expanding the head portion, and providing the pretensioning member.
