Patent ID: 8893990

Claim:
A system, comprising: a spray device, comprising: a frame having a receptacle configured to receive a self-contained spray can; a trigger assembly disposed within the frame and configured to selectively engage a spray of fluid from a spray nozzle of the self-contained spray can; a first conductive element configured to contact the self-contained spray can; a first electrical conductor extending between the first conductive element and an earth ground such that a first electrical potential of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the self-contained spray can is in contact with the first conductive element; a conductive pad coupled to the frame and configured to contact an operator hand; a second electrical conductor extending between the conductive pad and the earth ground; and a corona-charging electrode positioned adjacent to the spray nozzle of the self-contained spray can, wherein the corona-charging electrode is configured to emit a stream of ions toward the self-contained spray can such that the spray of fluid from the spray nozzle passes through the stream of ions and becomes electrostatically charged.
