A teat cleaning cup (130) for cleaning a teat (120) of an udder (110), which teat cleaning cup (130) comprises:

• a teat cleaner (300) comprising
• an inner body (270), forming a central cavity (280) configured to enclose a teat (120) of an udder (110), wherein the inner body (270) comprises
• an inner surface (271), facing the central cavity (280),
• an outer surface (272), and
• a set of apertures (275) extending from the outer surface (272) to the inner surface (271);
• an exterior part (220), enclosing the inner body (270);
• and
• a set of channels (291, 292) situated between the inner body (270) and the exterior part (220), which set of channels (291, 292) extend along a longitudinal direction of the teat cleaner (300) and connect to the set of apertures (275);
• a lower part (230) removably attached to the teat cleaner (300), which lower part (230) comprises
• at least one cleaning liquid valve (240, 260) connectable to a cleaning liquid supply, and
• a drain (250) for draining used cleaning liquid from the teat cleaner (300);
• and
• a seal (235) located between the teat cleaner (300) and the lower part (230), the seal (235) comprising a first surface (231) facing the teat cleaner (300) and a second surface (232) facing the lower part (230), the seal (235) including at least a first aperture (401, 403) in fluid communication with the at least one cleaning liquid valve (240, 260) to receive the cleaning liquid from the at least one cleaning liquid valve (240, 260) and distribute the cleaning liquid into the set of channels (291, 292) and via the set of apertures (275) to the central cavity (280) for spraying the teat (120) with the cleaning liquid,
• wherein the seal (235) includes at least one first set of apertures (401, 402, 403, 404) which include the at least a first aperture (401, 403) and a second aperture (402, 404) extending through the seal (235) from the first surface (231) to the second surface (232), and
• wherein the seal (235) forms at least one recess (233, 234) in the second surface (232), connecting the first aperture (401, 403) to the second aperture (402, 404).

A seal (235) of a teat cleaning cup (130) comprising a teat cleaner (300) and a lower part (230), the seal (235) comprising:

• at least a first aperture (401, 403);
• a first surface (231) configured for facing the teat cleaner (300) comprising an exterior part (220) that encloses an inner body (270) that forms a central cavity (280) configured to enclose the teat (120), a set of channels (291, 292) located between the exterior part (220) and the inner body (270), the set of channels (291, 292) extending along a longitudinal direction of the teat cleaner (300), the inner body (270) comprises a set of apertures (275) that connect the central cavity (280) to the set of channels (291, 292);
• and
• a second surface (232) configured for facing the lower part (230) of the teat cleaner (300), which lower part (230) comprises at least one cleaning liquid valve (240, 260) connectable to a cleaning liquid supply, and a drain (250) for draining used cleaning liquid from the teat cleaner (300), the set of channels (291, 292) and the set of apertures (275) providing a fluid path for the cleaning liquid supply to flow from the at least one cleaning liquid valve (240, 260) into the central cavity (280) for spraying the teat (120) with the cleaning liquid;
• wherein with the seal located between the teat cleaner (300) and the lower part (230), the at least a first aperture (401, 403) is in fluid communication with the at least one cleaning liquid valve (240, 260) to receive the cleaning liquid from the at least one cleaning liquid valve (240, 260) and distribute the cleaning liquid into the set of channels (291, 292) and via the set of apertures (275) to the central cavity (280) for spraying the teat (120) with the cleaning liquid, and
• the seal (235) includes i) at least one first set of apertures (401, 402, 403, 404) which include the at least a first aperture (401, 403), ii) a second aperture (402, 404) extending through the seal (235) from the first surface (231) to the second surface (232), and iii) a recess (233, 234) in the second surface (232), connecting the first aperture (401, 403) to the second aperture (402, 404).
