  • Patent number: 7395780
    Abstract: A milk collecting piece comprises a kink element having a bending edge which ensures reliable kinking and thus maintenance of the operating vacuum in milk tubes which are guided outwards in a direction oblique to the longitudinal axis. In one embodiment, the milk collecting piece comprises a connection surface provided with an opening into which an end portion of the milk tube is introduced, so that a reliable function is obtained due to the provision of the kink element, whereby due to the manner in which the milk tube is mounted on the collecting piece, a smaller amount of milk coating collects and deposits on transition areas. In a further embodiment, the bending edge of the kink element is positioned in such a manner that said edge efficiently prevents the milk tube from getting detached from connection elements which are guided outwards in an oblique manner, and ensures vacuum-tight kinking of the milk tube at the same time.

  • Patent number: 6920840
    Abstract: An apparatus for installing and removing a teat cup liner (or “inflation”) from a shell has a fixture which holds and retains the shell in position. A pair of shoes is capable of moving to engage a portion of the liner projecting from the shell to pull the liner downwardly. In an installation mode, the liner is pulled so that a sealing ring on the liner moves through a restricted opening into a sealing relationship with the shell at one end. The resiliency of the liner also causes a seal to be formed at the other end of the shell. In a removal mode, the liner is stretched by movement of the shoes in the same way as installation. A cutter of the apparatus is then activated to sever an end portion of the liner, including the sealing ring from the remainder of the liner, releasing the liner from the shell.

    Abstract: A milking inflation fits over the upper end of a teat cup shell, with a peripheral shoulder and cuff adapted to surround and sealingly engage the upper rim of the shell. A substantially flat, relatively thin section (mouthpiece) extends radially inwardly from the shoulder and toward a center portion which defines a circular central opening or mouth for receiving a teat of a lactating animal. A plurality of geometrically-shaped indentations are aligned in a circumferentially extending pattern around the mouth. The indentations are formed integrally in a broad surface of the mouthpiece and extend radially inwardly from the shoulder and cuff toward the center portion and central opening. The inward tips of the geometrical indentations leave a substantially raised portion around the center opening, and due to the alignment of the geometrical indentations there is an immediate raised portion around the central opening of the mouthpiece.

  • Publication number: 20020198489
    Abstract: Inner and outer shield parts of a breastshield are joined to form an enclosure defining a pressurizable chamber. The inner shield part has at least a portion thereof movable relative to the outer shield part when the chamber is subject to a negative or a positive pressure. A first pressure port is in communication respectively with the chamber for connection with a fluid pressure source of a first pressure. A second pressure port is in communication with the interior for connection with a pressure source of a second pressure. The breastshield is thus capable of being subjected to two different pressures, such as a positive pressure to move (expand) the chamber into the interior, so as to compress or massage the nipple/breast, and a negative pressure in the interior to draw the nipple/breast further therein for the expression of milk. The pressures can be independently controlled, and may furthermore alternate being negative and positive through the same pressure port.
