Abstract
A bovine teat sanitizer includes a gun-like grip handle, trigger mechanism and control poppet valve connected to a pressurized sanitizing fluid supply. A fixed in-line teat cup sized to receive a predetermined volume of fluid from a proportioning valve sufficient for treating four teats of the bovine is connected to the handle. A toroidal overflow chamber receives displaced fluid from the cup when the cup captures and essentially seals a teat thus forcing sanitizing fluid into the teat strep canal and epidermis. The cup is lowered and displaced fluid from the overflow chamber returns to the cup cavity by gravity for use on the second and succeeding teats. A splash guard and teat guide snaps onto the cup and forms the chamber top and inner sides.
