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.Type: GrantFiled: May 19, 2005Date of Patent: January 26, 2010Assignee: DeLaval Holding ABInventors: Torbjorn Petterson, Jan Kassibrahim

Publication number: 20090308320Abstract: A milking liner for an automated milking machine includes a barrel that moves between an uncollapsed position and a collapsed condition when it is subjected to a vacuum milking condition. The barrel defines at least three parallel channels open to the inner surface of the barrel. The configuration of the sidewall of the barrel and the channels cause the barrel to uniformly collapse when the barrel is subjected to a vacuum milking condition. In one configuration, ribs protrude from the barrel sidewall and define channels with the same wall thickness as the sidewall segments disposed between the ribs.Type: ApplicationFiled: August 24, 2009Publication date: December 17, 2009Inventor: Jin-Woong Shin

Patent number: 7540258Abstract: Apparatus for removing milk from a teat of an animal comprising an outer body having an opening into which the teat is insertable into a space defined by two or more resilient membranes. A pressure difference is applied between the space between the resilient membranes and a region outside the membranes to cause the membranes to ball on to the teat, thereby massaging it to extract milk. To avoid exerting excessive force on the end of the teat yet retain a useful massage pressure, the resilient membranes are under tension in a direction transverse to the direction of teat insertion before the provision of any pressure difference (before the insertion of the teat).Type: GrantFiled: October 17, 2005Date of Patent: June 2, 2009Assignee: Avon Polymer Products LimitedInventor: David Boast

Publication number: 20080202433Abstract: A teat cup comprises a flexible liner (3) for engaging about a teat of an animal to be milked, the liner having a head portion (7), at one end (6), provided with a mouth (9) through which the teat is engageable with the liner, and a milk discharge passageway (12) at the opposite end (5). A nozzle (24) is arranged to discharge fluid into the head portion of the liner, and a fluid delivery tube (21) is connected to the nozzle via a check valve (17) which allows fluid delivery to the nozzle and alleviates the risk of dirt or disinfectant lodging in the nozzle or delivery tube when the teat cup is treated on a jetter at the finish of a milking period.Type: ApplicationFiled: September 15, 2006Publication date: August 28, 2008Inventor: James Richard John Duke
