Abstract:
1. 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: 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.
