ABSTRACT:
An electrostatic spraying device is disclosed which is suitable for, but not limited to, dispensing an electrostatically sprayable substance for nasal or oral inhalation. Electrical charge is imparted to the spray particles by applying a high voltage to the substance prior to break up into a spray. In one embodiment, the device includes a nozzle portion for registry with the nasal or oral cavity and defines a passageway through which, in use, air can be drawn by inhalation on the part of the user. The substance to be sprayed passes into the passageway so that, with the assistance of user-induced air flow through the passageway, the resulting spray passes into the oral or nasal cavity.
