Teatcup liner

A teatcup to be applied to a teat of an animal, the teatcup comprising:

• a shell (3);
• and
• a teatcup liner (2),
• the teatcup liner (2) adapted to be mounted in the shell (3), the teatcup liner (2) defining an inner space (4) for receiving the teat and a longitudinal center axis (x) extending through and along the inner space (4), the teatcup liner further comprising
• a head portion (8),
• a tubular barrel portion (9), and
• a tubular lower portion (15) defining a milk channel (4′) having a cross-section area perpendicular to the longitudinal centre axis (x),
• the tubular lower portion (15) having a primary engagement member (16) adapted to be in engagement with a secondary engagement member (17) of the shell (3) in a mounted state when the teatcup liner (2) is mounted in the shell (3),
• the teatcup liner (2) also including a grip member (30) extending from the tubular lower portion (15) and adapted to be gripped by an operator during a mounting state when the teatcup liner (2) is to be mounted in the shell (3),
• the grip member (30) defining, during the mounting state of mounting the teatcup liner into the teatcup, a force application zone (34) on which a pulling force is to be applied by the operator, wherein the grip member (30) comprises two grip elements (31, 32), wherein each grip element seen along the longitudinal centre axis (x) is movable from an inactive position outside the cross-section area to an active position within the cross-section area,
• wherein a force application zone (34), for the operator applying the pulling force, as seen along the longitudinal centre axis (x), is located within the cross-section area of the milk channel (4′) of the tubular lower portion (15).
