Abstract
An inflation for a teat cup is made in the form of a silicone tube adapted to fit into, and seal the ends of, a teat cup. Pulsating pressure is applied to the outside of the inflation within the teat cup, and a low pressure line is attached to the downstream end of the inflation. An integral annular bead is spaced slightly less than a teat's length below the upstream end of the inflation. Axial ribs are spaced around the circumference of the tube upstream of the annular bead. The bead and ribs are resistive of collapse and therefore provide a gentle massaging action on the teat when the pulsating pressure is applied. In one important embodiment, the head of the inflation is provided with a pliant skirt and an annular cushion that fit against the teat and udder to minimize irritation and maximize retention of the inflation.
