ABSTRACT:
A teat cup has an outer rigid shell and an inner flexible inflation to receive an animal's teat in a pulsating elastic bore which is stretched by a spring or retaining member positioned between the shell and inflation. The stretched upper portion of the inflation becomes more responsive to the pulsations during milking. The spring member is fitted to the inflation near the upper mouth of the bore so that the member's lower portion bears on the inner surfaces of the shell or the spring member's shape inherently stretches the upper inflation area. Notches or openings and/or apertures are provided in the spring member to allow movement of the member as well as drainage of the teat cup when same is washed and inverted to dry.
