A teat cup lining to be applied in a teat cup for milking animals

Abstract: The invention relates to a teat cup lining (8) to be applied in a teat cup (1) for milking animals. Near its lower side the teat cup lining (8) is provided with a bent discharge line (15). The discharge line of the teat cup lining (8) is preferably bent through an angle of approximately 90° and constitutes an integral whole with the remaining part of the teat cup lining (8). The invention also relates to a teat cup (1) provided with a teat cup lining (8) in accordance with the invention.

Description: The invention relates to a teat cup lining according to the preamble of claim 1. Such a teat cup lining is known from the European patent application EP 0347954-A2. The invention aims at providing an alternative teat cup lining. According to the invention this is achieved in that the bent portion of the discharge line is provided with a profile, e.g. constituted by ribs. In this way the bent portion is strengthened and kept flexible. According to an inventive feature, the discharge line of the teat cup lining is bent through an angle from 55° to 125°, preferably of approximately 90°. According to again another inventive feature, the bent discharge line constitutes an integral whole with the remaining part of the teat cup lining, and the bent portion of the discharge line is made of the same material. According to a further inventive feature, the teat cup lining is made of flexible material, such as e.g. rubber or synthetic material. The invention also relates to a teat cup which is provided with a teat cup lining in accordance with the invention. According to an inventive feature, the teat cup comprises an elongated cylindrical housing and in that the end of the bent discharge line is bent through an angle of 90° and is located in the lower space of the cylindrical housing. The invention will now be explained in further detail with reference to an accompanying drawing in which Figure 1 shows a teat cup provided with a teat cup lining in accordance with the invention. Figure 1 shows a teat cup 1 comprising an elongated cylindrical housing 2. The cylindrical housing 2 is made of synthetic material. However, it is also possible to make the cylindrical housing 2 of metal or another kind of rigid material. Near its lower side the cylindrical housing 2 comprises a hose nipple 3 to which a (non-shown) pulsation hose can be connected. The hose nipple 3 constitutes an integral whole with the cylindrical housing 2. Near its lower side the teat cup 1 is provided with a conical seat 4 which is disposed in the teat cup 1 by means of a threaded connection. The conical seat 4 is dimensioned in such a manner that it is capable of cooperating with a conical recess of a teat cup carrier of a (non-shown) milking robot. In the middle of the conical seat 4 there is provided a borehole 5 through which a cable 6 is passed, which cable 6 is provided at its end with a spherical element 7. The spherical element 7 has a diameter which is larger than that of the borehole 5. The cable 6 belongs to a (non-shown) pulling back towards a position of rest on the teat cup carrier of a (non-shown) milking robot.

Claims: A teat cup lining (8) to be applied in a teat cup (1) for milking animals, which teat cup lining (8) is provided near its lower side with a bent discharge line (15), characterized in that the bent discharge line (15) is provided with a profile, e.g. constituted by ribs. A teat cup lining as claimed in claim 1, characterized in that the discharge line of the teat cup lining (8) is bent through an angle from 55° to 125°, preferably of approximately 90°. A teat cup lining as claimed in any one of the preceding claims, characterized in that the bent discharge line (15) constitutes an integral whole with the remaining part of the teat cup lining (8). A teat cup lining as claimed in any one of the preceding claims, characterized in that the bent discharge line (15) is made of the same material as the remaining part of the teat cup lining. A teat cup lining as claimed in any one of the preceding claims, characterized in that the teat cup lining (8) is made of flexible material, e.g. rubber or synthetic material. A teat cup which is provided with a teat cup lining (8) as claimed in one or more of claims 1-5. A teat cup according to claim 6, characterized in that the teat cup comprises an elongated cylindrical housing (2) and in that the end of the bent discharge line (15) is bent through an angle of 90° and is located in the lower space (14) of the cylindrical housing (2).
