Replaceable liner and teat cup shell for a teat cup assembly and method

摘要

A liner for use with a teat cup having a rigid hollow shell having a central aperture is shown. The liner comprises a teat chamber having an opening which extends axially therethrough and terminates in a distal end and which has an axial length greater in length than a length of a teat terminating in a distal tip which is to be inserted into the teat chamber. The liner includes a transition chamber having an axially extending reducing inner passageway which has an inlet contiguous to and communicating with the opening in the distal end. The transition chamber defines thereon a circumferentially extending cuff member configured to be passed through a central aperture in a shell and to them surround and urge the cuff member against a shell. A milk tube communicates with the outlet of the transition chamber.
