  • Patent number: 8079326
    Abstract: A teatcup and a teatcup liner are described. The teatcup liner (3) is adapted to be mounted in a shell (2) to form a teatcup (1) to be applied to a teat of an animal. The teatcup liner (3) defines a length axis (4) and an inner space (5) for receiving the teat, and includes a barrel (8) and an upper head (6) for receiving the teat, wherein the barrel (8) has an end portion (12) on which a primary engagement member (13) is arranged. The teatcup liner (3) includes a hindering member (15) arranged on the side of the primary engagement member (13) being distant from the upper head (6), hindering the primary engagement member (13) to bend away from the upper head, wherein the hindering member (15) has a smaller extension from the length axis (4) perpendicular to the length axis (4) compared with the primary engagement member.

  • Patent number: 8011321
    Abstract: A teatcup liner adapted to be mounted in a shell to form a teatcup to be applied to a teat of an animal, and a method of mounting a teatcup liner. The liner defines an inner space for receiving the teat and a longitudinal center axis. The liner has a head portion, a tubular barrel portion and, a tubular lower portion defining a milk channel having a cross-section area perpendicular to the center axis. The tubular lower portion has a primary engagement member to be engaged by a secondary engagement member of the shell. The liner includes a grip member extending from the tubular lower portion to be gripped by an operator when the liner is to be mounted. The grip member defines a force application zone on which a pulling force is to be applied and which seen along the center axis is located within the cross-section area.

  • Patent number: 7856942
    Abstract: A milking device includes at least a teat-receiving flexible sleeve, adapted to be positioned on/over a teat. A first portion thereof includes a material, selected from the group consisting of thermo-plastic elastomers (TPE), as defined in ISO 18064, and a second portion thereof includes a material selected from the group consisting of thermoplastics. The method of making a milking device, in particular a teat cup liner, is a molding process carried out in two or more steps. In the first step, a thermoplastic, preferably polypropylene (PP) or polyamide (PA), is injected in a mold defining only those portions of the device that are to exhibit a higher stiffness or rigidity, such as couplings. The stiffer parts, are demolded from the mold, and placed in a second mold, into which, as a second molding step, a suitable TPE is injected. Further steps can be performed if required by the design.

  • Patent number: 7650854
    Abstract: This invention refers to a teatcup liner and a teatcup. The liner (1) is mounted in a shell (2) of the teatcup and defines an inner space (3) for receiving a teat. The liner includes a primary component (12) forming a barrel. The primary component includes a peripheral portion (15), a primary connecting ring (16) and a lip (17) defining an opening (4). The secondary component includes a secondary peripheral portion (18) and a secondary connecting ring (20). The primary component is connectable to the secondary component for releasing the liner by a mutual engagement of the connecting rings. At least one of the connecting rings abuts the peripheral portion of the other component to form a sealing abutment between the two components.

  • Publication number: 20060219180
    Abstract: The invention refers to a set of four teatcup liners (4, 5) and to a milking member. The milking member includes a claw (1) and four teatcups (2) to be attached to a respective teat of an animal to be milked. Each teatcup liner has a liner portion adapted to be received in one of the teacups and a conduit portion (9) adapted to extend between the respective teatcup and the claw. The conduit portion of each teatcup liner has at least one property influencing the operation of the teatcup liner during milking. The property of a first pair or the four teatcup liners differs from the property of a second pair of the four teatcup liners.
