Abstract: The invention refers to a teatcup liner, a teatcup and a milking member. The liner (1) is mountable in a teatcup shell (2) having a first end (3) and a second end (4) to extend through the shell, and forms an inner space to receive a teat and an outer space (6) between the shell and the liner. The liner includes an opening at the first end for introducing a teat into the inner space. The liner includes a grip area (10) to be gripped by a grip portion (11) of the shell. The grip area has a non-circular shape. The liner includes a connection portion (15) arranged to connect the liner to the first end and including an annular recess. The connection portion includes a bridge of material (18) arranged to define at the most two possible rotary positions for the liner in relation to the teatcup shell. The bridge extends in the annular recess and is arranged to engage a corresponding recess (19) extending from the first end of the shell.

Abstract: A teat cup system including a tubular sleeve, a milk receiving cup having a portion configured to be operatively coupled to a lower end portion of the tubular sleeve, and a liner member including a head portion and a tubular elongate inflation portion and wherein the tubular elongate inflation portion is configured to be inserted through the tubular sleeve so that the head portion of the liner is disposed around an upper end portion of the tubular sleeve and the elongate inflation portion disposed within the tubular sleeve, and a bottom end of the tubular elongate inflation portion invertedly drawn around a lower end portion of the tubular sleeve, a portion of the milk receiving cup capturing the inverted free end between the lower end portion with an interference fit.

Abstract: A teatcup liner and teatcup assembly are provided with controlled collapse constructions including ribs, notches, sleeves, and thickness variations.

Abstract: A variable shut off teat cup liner has a mouthpiece, a barrel and a short milk tube adapted for mounting onto milking claw. The short milk tube includes a segment for engagement with an edge of a claw nipple defining an opening, the segment being intended for bending over the opening to substantially close it to passage of vacuum-drawn air therethrough when the teat cup liner is in a non-milking generally downwardly bending position. The segment has circumferentially extending grooves and longitudinally extending grooves which form lugs which provide improved cut resistance. The circumferentially extending grooves have different axial spacing whereby the amount of overlap of the short milk tube over the nipple may be varied to provide the proper amount of bending.

Abstract: The invention refers to a teatcup liner, a teatcup and a milking member. The teatcup liner is mountable in a teatcup shell, having a first end and a second end, such that in the mounted state it extends through the teatcup she 1 and forms an inner space for receiving a teat and an outer space between the teatcup shell and the teatcup liner. The teatcup liner also includes a grip area which has a non-circular shape in cross-section and is arranged to be gripped by a grip portion of the teatcup shell such that the grip area is surrounded by and abuts the grip portion. The teatcup liner has a connection portion for connection to a teatcup claw and includes structure for defining a rotary position for the teatcup liner in relation to the teatcup claw.

Abstract: A method and apparatus providing a teat cup assembly. The teat cup assembly includes a tubular sleeve, a milk receiving cup and a liner member. The liner member includes a head portion and a tubular elongate inflation portion. The head portion includes an upper teat chamber defined with a cylindrical wall having an outer exposed surface, an intermediate wall extending substantially orthogonally inward from the cylindrical wall and an upper seal wall laterally extending inward from the cylindrical wall having a central opening defined by the upper seal wall. The cylindrical wall of the head portion includes a cylindrical retaining extension configured to cooperate with and be coupled to an upper end portion of the tubular sleeve. The tubular elongate inflation portion includes side walls with opposite first and second ends defining a liner bore longitudinally along a length of the tubular elongate inflation portion with opposite first and second open ends.

Abstract: According to the invention, a liner is provided for use with a substantially undeformable teatcup shell (40), for forming a two-chambered teatcup, by means of which milk is extracted from a teat (Z) in a suction milking process through a milking vacuum provided during a milking phase, and the teat is massaged during a rest phase, wherein the liner comprises a head part (12) that is substantially rotationally symmetrical relative to its longitudinal axis and a barrel part (14) that is connected to the head part (12) by means of a transitional part (22), the barrel part (14) is flexible, surrounds the teat and reacts to alternating changes in pressure during the milking and rest phases by changing its form, the head part (12) is formed as an annular tube (16), which forms an insertion opening (18) for the teat (Z), and which ensures sealing relative to the milking vacuum and the best possible grip of the liner to the teat without excessively constricting the teat during both the milking and the rest phases, the

Abstract: The teatcup includes a teat inlet end and a milk discharge end, a liner insertable within and supported by the teatcup and having a teat inlet opening at the teat inlet end of the teatcup, characterized by a milk chamber within the milk discharge end of the teatcup, a milk discharge tube extending sideways through a side wall portion of the chamber and being adapted for discharging milk from the chamber via a suction tube arranged in the chamber and having a milk inlet opening adjacent to a bottom surface in the chamber.

Abstract: A teat cup comprising a liner having movable thin-wall portions which are adapted to be differently pressurized is disclosed.

Abstract: A modular teat cup assembly for use with a milking machine for milking cows. The modular teat cup assembly comprises a hollow tubular shell together with a cartridge assembly slidably received within the shell. The cartridge assembly includes a spool-shaped liner and a framework comprising a pair of opposing sleeve members for supporting the liner. The sleeve members are movable between an open position to permit removal and replacement of the liner, and a closed position for supporting the liner therebetween. A cap removably mounted on the bottom of the shell holds the cartridge assembly within the shell and is used to attach a milking tube in the conventional manner. A head piece includes a mouth for receiving a cow's teat, and is snapped onto the upper end of the shell to complete the modular assembly.
