ABSTRACT:
A closure for a teat cup with a resilient inner liner in the shape of a small disk with a centrally located bulge. A farmer who has to milk fewer than four teats on any cow because of injury to or disease in one of them can utilize the closure to adapt an automatic milking machine of the conventional type to harvest her milk. The disk is large enough to cover the opening in the teat cup liner otherwise provided for the reception of a teat so that the flow of air therethrough can be cut off when a vacuum is applied to the passageway which terminates in this opening. The bulge with its gently sloping, raised surface increases the area of contact between the disk and the lip of the liner to aid in sealing the disk to the cup under vacuum conditions and prevents the disk from slipping sideways. A magnet secured to the back side of the closure, opposite the bulge, facilitates storage.
