Abstract
A liquid container is provided adapted to form a part of apparatus for electrostatic spraying of liquids, such as pesticides. The container includes a body having an orifice for delivering liquid to a spray nozzle, and a closure for sealing the orifice prior to location of the container on the apparatus. The orifice is opened only when the container is mounted on the apparatus, and the orifice is reclosed when removed from the apparatus. An electrostatic valve may comprise the closure.
Claims5
A liquid container adapted to form part of apparatus for electrostatic spraying, the apparatus including a power supply, high voltage generator having input and output terminals, a spray nozzle at least part of the surface of which is electrically conductive, an electrode disposed adjacent the nozzle and insulated therefrom, with electrical connections for connecting the power supply to the input terminals of the generator and the electrode to one output terminal of the generator and the nozzle to the other output terminal of the generator;
- the container comprising:
- a body having an orifice for delivering liquid;
- mounting means for locating the container on the apparatus in a position in which the orifice can deliver liquid to the spray nozzle, the mounting means including a conductor or conductors forming part of the electrical connections for the apparatus;
- and
- closure sealing means for closing the orifice prior to location of the container on the apparatus and so that the orifice is opened when and only when the container is mounted on the apparatus.
