Electrostatic spray system

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 a body of 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 body of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the body of the self-contained spray can is in contact with the first conductive element;
• a second conductive element configured to contact a neck of the self-contained spray can;
• a second electrical conductor extending between the second conductive element and the earth ground such that a third electrical potential of the neck of the self-contained spray can is substantially equal to the second electrical potential of the earth ground while the neck of the self-contained spray can is in contact with the second conductive element;
• and
• an indirect charging device configured to electrostatically charge the spray of fluid from the spray nozzle.

• an indirect charging device configured to electrostatically charge the spray of fluid from the spray nozzle;
• a first conductive element configured to contact a neck of the self-contained spray can;
• a second conductive element also configured to contact the neck of the self-contained spray can, wherein electrical current to the indirect charging device is interrupted if the neck of the self-contained spray can does not contact the first conductive element and the second conductive element;
• and
• a first electrical conductor extending between the first conductive element or the second conductive element, and an earth ground such that a first electrical potential of the neck of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the neck of the self-contained spray can is in contact with the first conductive element or the second conductive element.
