Abstract
Abstract A B S T R A C T 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 mechanical means 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 1 micron in the gas phase, after spraying has 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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
79 words
1/ A method of dispensing, issuing, or diffusing a liquid, the method including using a spray pump type dispenser which expels liquid through a nozzle under internal pressure, the method being characterized by the use of mechanical means during the expulsion stage for obtaining an instantaneous internal pressure that gives rise to a spray in which the particles of divided liquid are not greater than about 45 microns in size, depending on the surface tension of the expelled liquid.
Claim 2
Dependent Claim
79 words
1/ A method of dispensing, issuing, or diffusing a liquid, the method including using a spray pump type dispenser which expels liquid through a nozzle under internal pressure, the method being characterized by the use of mechanical means during the expulsion stage for obtaining an instantaneous internal pressure that gives rise to a spray in which the particles of divided liquid are not greater than about 45 microns in size, depending on the surface tension of the expelled liquid.
Claim 3
Dependent Claim
38 words
2/ A method according to claim 1, characterized in that the pump volume lies in the range about 5 microliters to about 100 microliters, and expulsion takes place in a period of time no greater than 10 milliseconds.
Claim 4
Dependent Claim
59 words
3/ A method according to claim 2, characterized in that the spray is directed towards a smooth surface in order to cause the particles to be fractioned by impact, thereby obtaining particles of divided liquid having a size no greater than about 1 micron, said surface being maintained at a determined temperature, above the vaporization temperature of the liquid.
Claim 5
Dependent Claim
26 words
4/ A method according to claim 3, characterized in that the smooth surface is a ceramic caused to vibrate by means of a piezoelectric ultrasonic transducer.
Claim 6
Dependent Claim
105 words
5/ A diffuser for implementing the method of any one of claims 1 to 4, the diffuser including a spray pump having a volume lying in the range 5 microliters to 100 microliters and a pump actuating pushbutton (4,50) for transmitting force to a liquid delivery piston when thrust is applied thereon, a return spring returning the piston towards a rest position, and an outlet spray nozzle for dividing the liquid by the pressure effect, the diffuser being characterized in that it includes mechanical actuator means (10, 12-22, 26) for applying thrust on the push-button for a period of time shorter than about 10 milliseconds.
Claim 7
Dependent Claim
17 words
6/ A diffuser according to claim 5, characterized in -that -the mechanical means is a spring (26).
Claim 8
Dependent Claim
25 words
7/ A diffuser according to claim 5, characterized in that the actuator means for the pump is a plunger (10) controlled by a solenoid (12).
Claim 9
Dependent Claim
30 words
8/ A diffuser according to claim 5, characterized in that the mechanical means include at least two magnets (86, 87) whose relative positions give rise to mutual attraction or repulsion.
Claim 10
Dependent Claim
34 words
9/ A diffuser according to claim 7, characterized in that permanent magnets (14) are provided to attract the plunger (10) so as to balance, at least in par-t, the return spring of the pump.
Claim 11
Dependent Claim
44 words
A diffuser according to claim 7, characterized in that when in the rest state, the plunger is at a distance from the push-button of the pump, so that the plunger travels a distance "d" prior to driving the pushbutton, each time it is actuated.
Claim 12
Dependent Claim
32 words
11/ A diffuser according to any one of claims 5 to 10, characterized in that it includes a smooth fractioning surface, with means (32, 44, 45) for heating it to constant temperature.
Claim 13
Dependent Claim

12/ A diffuser according to any one of claims 5 to 11, characterized in that it further includes means for establishing a flow of air around and inside the spray and in the same direction.
Claim 14
Dependent Claim
35 words
13/ A diffuser according to claim 11, characterized in that the heater means are servo-controlled to ambient temperature, to the temperature of the liquid to be fractioned, and to the boiling temperature of said liquid.
Claim 15
Dependent Claim
24 words
14/ A diffuser according to claims 5 or 7, characterized in that it includes repetitive control means, e.g. a frequency, for obtaining pseudo-continuous operation.
