  • Patent number: 4320718
    Abstract: A rubber teat holder has a head portion rotationally symmetrical with respect to a longitudinal axis and with an inlet opening for the teat, and has a holding edge for gripping over a milking cup sleeve. The head portion is formed by a wall which first gradually enlarges radially from said inlet opening in a direction along the longitudinal axis and then tapers back to a flexible suction sleeve which is connected to the head portion and is slightly conical or substantially cylindrical. Upon application of an axial force on the edge of the inlet opening the upper enlarging part of the head portion, which forms a flexible lip at the inlet opening, can move relative to the lower tapering part of the head portion around a part of the head portion, which part acts as a first spring joint. The first spring joint is formed by the wall portion approximately at the maximum outside diameter of the head portion.
