| 20090194034 | TEAT FOAM RING - A teat foam ring connected to a supply of pressurized cleaning solution and a supply of pressurized air. The teat foam ring includes a cleaning solution inlet and defines a cleaning solution channel and an extrusion slot. Cleaning solution and compressed air flow into the ring through the cleaning solution inlet and into a cleaning solution channel. The cleaning solution is expelled from the ring through the extrusion slot as a foam. The extrusion slot extends upwardly and inwardly so that the foam forms a cone supported on an upper surface of the ring over the central opening in the ring. The teat foam ring may include or be connected to a mixing chamber for transforming the cleaning solution and the compressed gas into a foam. The mixing chamber may be defined within the inlet of the teat foam ring. A mixing medium may be located in the mixing chamber. | 08-06-2009 |
