Abstract
A container for the electrostatic spraying of liquids, especially pesticides, having an integral conductive spray nozzle formed from two concentric tubes in which axial ribs and grooves between the tubes provide a liquid pathway to the nozzle mouth. Air is bled into the container in use through an extended pathway provided by a helical thread on the surface of a bung in the upper end of the inner tube.
