Abstract
Liquid to be dispensed is supplied to a dispensing nozzle (88) from a compressible container (30) such as a sachet with a valve-controlled outlet (66) by compressing the sachet through the agency of a pad (46) of resiliently deformable material. The dispensing device is embodied in a hand held unit having a trigger (102) and electrical circuitry (91, 96, 106, 98, 106) for applying high voltage to the liquid in order to effect dispensing of the liquid in the form of an electrostatically charged, atomised spray.
