Electrostatic spraying device

An electrostatic device configured and disposed to electrostatically charge and dispense a liquid composition from a supply to a point of dispense,

• wherein the device comprises:
• an actuator;
• a high voltage generator to provide a high voltage;
• a power source to activate said actuator and said high voltage generator;
• a reservoir to contain the supply of said liquid composition;
• and
• a dispensing unit comprising:
• a means for supplying the liquid composition from the reservoir, said supplying means being mechanically connected to said actuator to be driven thereby;
• an emitter electrode to electrostatically charge the liquid composition, the emitter electrode being electrically connected to said high voltage generator;
• and
• a nozzle to dispense the liquid composition, said nozzle being disposed at the point of dispense;
• wherein the device further comprises a field electrode surrounding the reservoir, said field electrode being connected to the high voltage generator;
• and
• wherein the reservoir is configured to provide a removable cartridge, said reservoir at least partially being made of deformable material;
• and
• wherein the emitter electrode and the field electrode provide the entire liquid composition with more or less a common electric potential, and
• wherein said device includes a housing carrying said actuator, said high voltage generator, and said power source,
• said housing being formed with a concavity for detachably receiving said reservoir,
• said housing incorporating an electric motor which drives said actuator for operating said supplying means, and
• said reservoir being shaped to have a planar configuration of a general segment of circle defined between a chord and a circumference of an approximate circle which is greater than a circumference of a semicircle,
• said mouth being disposed at a center of said chord.
