Abstract
A container for containing a liquid that has suspended particles used for depositing on a substrate is formed of an electrically conductive material, and has a bottom wall. An atomizer for atomizing the liquid and particles to form an aerosol is mounted at an upper end thereof. A bottom wall of the container has a piezoelectric ultrasonic transducer attached to the wall. A high voltage connection to the piezoelectric transducer is in a recess formed by a lower skirt on the container and is mounted in an insulating block in the recess. A cup shaped insulating sleeve slips over the lower portions of the container and shields the high voltage connection from the exterior.
