TEAT CUP LINER Russian patent published in 2013 - IPC A01J5/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to machine milking of cows, goats and other mammals. The teat cup liner consists of a suction part (1), a middle part (3) and a milk hose (4). All elements of the teat cup liner are made of silicone. The upper annular edge (2) of the suction part imitates the shape of the calf's lips and softly copies the teat surface with any shape and size. The upper annular edge is formed by an elastic tube with a compensation groove (5) and the inner space (6). The suction chamber interior varies depending on the size of the teat. The middle part of teat cup liner has helical grooves (7) of rounded shape with a maximum depth near the suction part with a gradual decrease to the milk hose, creating the effect of a natural suckling by a calf. The milk hose has sealing rings (8), as well as technological beads (9) in the form of a protrusive ridge surface.

EFFECT: increased amount of milk and improvement of its quality, increased duration of exploitation of animals, as well as a range of sizes and shapes of teats.
