Mixing apparatus and method for the repair of can ends

A mixing apparatus for the repair of coating adhered on a can end, comprising:

• a plurality of holding tanks in fluid communication with a first fluid delivery system and a single mixer,
• the first fluid delivery system having a plurality of valves coupled to the holding tanks, wherein the valves selectively flow liquids or fluids held in the holding tanks into the first fluid delivery system,
• the first fluid delivery system having a plurality of individual conduits and a plurality of pumps, wherein the pumps pump the liquids or fluids to flow the liquids or fluids into the single mixer, each of said liquids or fluids being independently delivered from a corresponding one of said holding tanks to the single mixer via a corresponding one of said individual conduits;
• a pressure tank in fluid communication with the single mixer;
• a relieving type pressure regulator coupled to the pressure tank;
• and
• a spray device in fluid communication with a second fluid delivery system and the pressure tank,
• wherein the plurality of liquids or fluids are mixed in the single mixer to yield a mixed solution which is flowed into the pressure tank, and
• wherein pressure in the pressure tank flows the mixed solution through the second fluid delivery system and dispenses the mixed solution on the can end.
