ABSTRACT:
A method of dispensing, issuing, or diffusing a liquid (volatile or otherwise) without using a propellant gas, the liquid being a perfume, a cosmetic, an insecticide, or a medicine, for example. The method consists in using a pump type spray head where a liquid is sprayed by being expelled under pressure through a nozzle, and being characterized by the use of a mechanical device during the expulsion stage for obtaining an instantaneous pressure which causes a dose or a spray to be delivered comparable to an aerosol of the type obtained when using a compressed or liquefied propellant gas i.e. an aerosol in which the particles of divided liquid are not greater than 45 microns in size in the liquid phase, and are less than 1 micron in the gas phase, after spraying has occurred, and without spoiling the sprayed substances. The invention also relates to an exclusive or protective system which is personalized by encoding-decoding means that may be mechanical, electronic, or both, assisted by means of an audio-electronic speech synthesis system.
