Description

Device for emitting an adaptable olfactory composition, kit for emitting an olfactory composition and method allowing such emission

The invention relates to the field of providing olfactory ambiance for living spaces.

The invention more particularly relates to a method for delivering an olfactory composition and a system for delivering such an olfactory composition.

State of the prior art

It is known to add ambiance to living spaces by using devices for emitting an olfactory composition based on sprayers comprising a cartridge of a mixture of perfume and propellant gas. If it is possible to vary the olfactory ambiance of one's interior by changing the cartridge or by using 2 or 3 combined or alternating devices, the number of accessible ambiances remains limited and requires active intervention from the user to change the atmosphere. 'atmosphere.

Thus, there would be an interest in a device for emitting an olfactory composition which allows easy adaptation of the latter without active intervention, such as a change of cartridge, from the user.

The invention aims to remedy the above drawback and thus aims to provide a device for emitting an olfactory composition capable of allowing the emission of an olfactory composition which can be adapted without active intervention by the user. , that is to say without having to change a cartridge or trigger another emission device.

To this end, the invention relates to a device for emitting an adaptable olfactory composition comprising:
- at least two housings each intended to receive a respective capsule containing a possible compound of said olfactory composition preferably in the form of solid granules, each capsule having a perforated outlet face in order to allow diffusion of the compound through the outlet face of the capsule housed in said housing,
- for each housing, a variable diffusion generation system in order to generate a variable diffusion of the compound through the exit face of the capsule housed in said housing,
the emission device being further configured to vary the diffusion of compound generated by each of the variable diffusion generation systems in order to vary the proportion of the compounds in the olfactory composition emitted by the emission device.

With such a device, it is easy to adapt the olfactory composition by simple modulation of the diffusion of each of the compounds generated by the variable diffusion generation systems. It is thus easy to go from an olfactory composition composed of 100% of a compound from a given capsule, that is to say a single variable diffusion generation system generating a diffusion of compound, to an olfactory composition composed of the compounds of two capsules, this by switching on or another variable diffusion system. Of course, in accordance with the invention, such a variation in no way requires active intervention from the user, since it can, according to one possibility of the invention, be obtained by a simple software command.

It should be noted that in the context of this document, if “emission” terminology of the olfactory composition is used, such terminology is used in order to cover an active diffusion of the different compounds included in said olfactory composition. It is noted that in the present invention, the physical phenomenon allowing such emission is a forced diffusion of the different compounds provided by the passage of air flows along an air flow path of corresponding capsules or a diffusion thermal linked to the use of a heating system of the variable diffusion generation system.

Each housing is intended to house a capsule also having a perforated inlet face so as to define an air flow path between the inlet face and the outlet face, each variable diffusion generation system being formed by a variable air flow generation system capable of generating a variable air flow at said housing along the air flow path, each variable diffusion generation system preferably comprising at least one fan, the variation in the generated air flow then being provided by a variation in the rotation speed of said fan.

Such an air flow generation system makes it possible to easily adapt the composition of compounds of the composition, since a simple start or stop of the air flow, for example by stopping or starting a fan, makes it possible to add or delete one of said compounds.

It will be noted that according to this possibility, the compound contained in a capsule is advantageously supplied in the form of granules.

According to a variant of the invention, each diffusion generation system may comprise a heating system, such as a heating resistor, adapted to heat the corresponding capsule, and therefore the compound it contains, in order to induce diffusion thermal of said compound.

Such a heating system allows good diffusion of the compound without necessarily needing to move any mechanical part. Thus, a transmitting device without a moving mechanical part is particularly reliable and presents little risk of breakdown.

According to a variant of the invention, each diffusion device can comprise a power supply circuit for a heating resistor and a connector connected to said power supply circuit and arranged in the housing being configured to connect with a complementary connector of a capsule housed in said housing, the capsules intended to be housed in said housing each having the complementary connector and a heating resistor connected to the complementary connector in such a way that when said capsule is housed in the housing, the heating resistor is connected to the circuit of power supply to the variable diffusion generation system.

With such a configuration, the heating resistor can be as close as possible to the compound and allows good heat transfer in the compound to allow good diffusion of the compound.

In the case where the variable diffusion generation system is based on thermal diffusion, the compound does not have to allow air to pass through as is the case for an air flow generation device.

The emission device may further comprise a body, the housings opening onto one face of the body and the body housing each of the variable diffusion generation systems in such a way that the outlet face of the corresponding capsule is in fluid communication with a end of the corresponding housing which is opposite the face of the body, the housing being shaped in such a way that a capsule which is housed there presents its outlet face facing the variable diffusion generation system.

Each air flow generation system may include a compound emission pipe, said pipe being preferably common to the air flow generation systems.

Such an emission pipe allows the different compounds to be brought outside the device to allow their combination in the form of the olfactory composition and their emission.

Each variable diffusion generation system may include a cavity supplied by the compound after its passage through the exit face of the capsule.

Such a cavity allows concentration of the compounds before their emission to the outside.

Each housing can be equipped with a detector capable of detecting the presence of a capsule in said housing, the detector being preferably capable of identifying the compound that the capsule contains.

With such a detector, the device is able to identify each capsule and the compound it contains and thus determine the different olfactory compositions that it is able to emit.

The emission device may further comprise a control circuit adapted to control the diffusion of compound generated by each of the variable composition generation systems as a function of the olfactory composition to be emitted.

Such a control circuit can make it possible to make the transmitting device autonomous and also makes it possible to connect to a mobile terminal in order to allow its configuration.

The emission device can be configured to emit concomitantly, or independently of the emission of the olfactory composition, another stimulus from among a sound stimulus and a visual stimulus.

Such a possibility of emitting a secondary stimulus makes it possible to perfect the olfactory atmosphere offered by the emission device according to the invention.

The invention further relates to a capsule for an emission device according to the invention, the capsule containing a compound capable of participating in an olfactory composition emitted by the emission device, the compound being preferably in the form of granules, the capsule having a perforated outlet face in order to allow diffusion of the compound through the outlet face by means of a variable diffusion generation system capable of generating a variable diffusion of the compound through said outlet face.

Such a capsule is capable of cooperating with a broadcast device according to the invention and thus makes it possible to benefit from the advantages linked thereto.

The invention also relates to a kit for emitting olfactory compositions comprising:
- a transmission device according to the invention, and
- at least one capsule according to the invention.

Such a kit allows you to benefit from the advantages linked to the emission device it includes.

According to a possibility compatible with the invention but which is not limited to the latter, the emission device can be configured to implement a method for emitting an olfactory composition, the olfactory composition comprising at least a first compound of a type selected from a compound of the top note type and a compound of the heart note type, and at least a second compound of a type selected from a compound of the heart note type and a compound of the base note type, the first and the second compound being compounds of a distinct type, the method comprising a step of emitting the olfactory composition with a variation of the respective composition of the first and the second compound over time to take account of the difference volatility between the first and the second compound.

Thus, the first compound having a greater volatility, the olfactory composition can, firstly, present a given composition, such as that determined according to the process of the present invention, and present, secondly, a composition in which the proportion of the first compound is increased to compensate for its greater volatility relative to that of the second compound.

Likewise, according to this possibility compatible with the invention, the olfactory composition can comprise at least the first compound of a top note type, the second compound of a heart note type and a third compound of a heart note type. basically, during the step of emitting the olfactory composition, the olfactory composition presents a variation of the respective composition of the first, the second and the third compound over time to take into account the difference in volatility between the first, the second and third compounds.

Thus in an identical manner, the first compound presenting a greater volatility than the second compound which itself presents a greater volatility than the third compound, it is possible to correct this difference throughout the emission of the composition. volatility. Thus, the olfactory composition can present, initially a given composition, in a second step, the composition is corrected to increase the relative proportion of the first compound then in a third step, the composition can be corrected to increase the relative proportion of the second compound.

In this way, it is possible to perfect the olfactory atmosphere provided by the emission device so that the latter is not or only slightly affected by the difference in volatility between the different compounds of the latter.

Detailed presentation of particular embodiments

There shows a delivery system 1 of an olfactory composition capable of emitting an olfactory composition.

If such a delivery system 1 is particularly suitable for ambience the interior of a user's home, the invention is not limited to this use alone. Thus, such a delivery system 1 can equip a user's vehicle, office premises, common areas or even commercial premises, such as stores or restaurants, without departing from the framework of the 'invention.

It will be noted that in the context of this embodiment, as shown in the , the delivery system 1 comprises more precisely a device 10 for emitting the olfactory composition and a mobile terminal 30 of the mobile telephone type or more precisely of the smart phone type (better known under the English name smartphone).

The device 10 for emitting an adaptable olfactory composition comprises, as shown in Figures 1B and 1C:
- a body 12 of emission device 10 having three housings 13A, 13B, 13C each receiving a respective capsule 20A, 20B, 20C containing a possible compound of said olfactory composition in the form of granules 23, each capsule 20A, 20B, 20C having an entry face 21A, 21B, 21C and an exit face 22, as will be discussed in connection with Figures 5A and 5B,
- a cover 11 having an outlet 14 through which the olfactory composition is emitted.

We can see on the that in the present embodiment, the body 12 and the cover 11 are assembled to take the shape of a flower, the cover 11 presenting the petals, the body 12 the base of the flower. Of course, such a shape is only one example of a particularly advantageous embodiment of the invention, the emission device 10 being able to take other shapes, such as a cylindrical, parallelepiped shape or even, as a decoration any human, animal or plant form, without departing from the scope of the invention. Indeed, the shape of the emission device preferably has a shape adapted to be installed in a home without damaging the decoration. It can be noted that it is also possible for the device to have a functional shape, such as a shape allowing installation on the ceiling of the home.

The body 12 has a housing 12B housing the different functional elements of the emission device 10 and a cover 12A closing the housing and making it possible to accommodate the cover 11. The cover 12A, as shown on the , has three openings each corresponding to a respective housing 13A, 13B, 13C. These openings are sized to accommodate the 20A, 20B, 20C capsules.

There illustrates the body 12 after removal of the cover 12A in order to show the functional elements of the emission device 10, the capsules 20A, 20B, 20C being figured to show their arrangement with respect to these same functional elements.

As shown in Figures 2 and 3, the transmitting device 10 further comprises, housed in the housing 12B:
- an aeraulic circuit in order to provide an emission circuit for the olfactory composition, the aeraulic circuit comprising a base 163 delimiting three reception cavities 165A, 165B, 165C for receiving and guiding a flow of air after its passage through the capsule 20A , 20B, 20C corresponding; a support plate 161 and a tube 162 supported by the latter to guide the air flow after its reception by the receiving cavities in the direction of the opening 14,
- for each housing 13A, 13B, 13C, a fan 18A, 18B, 18C capable of generating the variable air flow, each fan 18A, 18B, 18C being arranged between the housing and the corresponding receiving cavity 165A, 165B, 165C in order to suck air from the corresponding capsule 20A, 20B, 20C towards said receiving cavity 165A, 165B, 165C,
- for each housing 13A, 13B, 13C, a detector 17A, 17C configured to detect the presence of the capsule 20A, 20B, 20C in said housing and determine the compound it contains,
- a control circuit 15 configured to control the rotation speed of the fans 18A, 18B, 18C and thus adapt the respective proportion of the compounds included in the olfactory composition,
- two speakers 19, only one being shown, adapted to provide sound stimuli in the form, for example, of music or a natural sound (wave, birdsong or even the sound of a waterfall),
- a power source, such as one or more accumulators or batteries, or batteries, not shown.

According to the invention, the power source is preferably provided by one or more lithium-based batteries such as lithium-ion or lithium-polymer batteries. It will be noted that as a variant, or in addition, the power source can be supplied by a sector power supply, for example in the form of a transformer capable of supplying, from a sector voltage, such as a alternating voltage of 220V or 110V, a direct voltage whose voltage can be between 2 and 20V, preferably between 4 and 12V.

It will be noted that according to an advantageous possibility of the invention, the control circuit 15 can also include a lighting system, such as light-emitting diodes, or LEDs, not referenced, in order to provide a visual stimulus, such as lighting. constant or changing color. According to this possibility, the body 12, and possibly the cover 11, are made of a translucent material in order to allow diffusion of the light emitted by the lighting system. The lighting system is advantageously chosen to present variable light emission in color/temperature and intensity.

As shown on the , the cover 12A has three openings configured to receive a respective capsule 20A, 20B, 20C. The cover 12A also has side walls, not shown, which extend said openings by laterally delimiting at least partially said housing 13A, 13B, 13C. The housings 13A, 13B, 13C are limited, opposite the corresponding opening, by the support plate 161. The support plate 161, in order to allow the passage of the air flow generated by suction by the fans 18A, 18B , 18C, has gills. The support plate also presents the detectors 17A, 17C which are each arranged to come into contact with the corresponding capsule 20A, 20B, 20C when it is housed in the housing 13A, 13B, 13C.

Each detector 17A, 17C comprises, as shown in Figures 2 and 3, an arm having on one end which is housed in the housing two metal contacts arranged to come into contact with two complementary metal contacts 24, shown on the , of the corresponding capsule 20A, 20B, 20C. The capsule 20A, 20B, 20C further comprises, between these two complementary metallic contacts 24, a resistor 25A, which will be described in connection with the , connecting these two complementary metallic contacts 24 together and whose value is chosen to correspond to the compound which is contained by the capsule 20A, 20B, 20C. The control circuit is configured, from the two metal contacts of each of the detectors 17A, 17C, to detect the presence of the capsule 20A, 20B, 20C, the resistance 25A making it possible to close the circuit between the two metal contacts of the corresponding detector 17A, 17C, and to identify the compound associated with said capsule by measuring the resistance 25A. To do this, the control circuit 15 may include a current measurement or resistance measurement circuit, not shown.

For each accommodation, as shown on the , the corresponding fan 18A, 18B, 18C is arranged between the support plate 161 and the receiving cavity 165A, 165B, 165C. In accordance with the invention, each fan is adapted and arranged to generate a variable air flow at the corresponding housing 13A, 13B, 13C and more specifically at the capsule 20A, 20B, 20C which is housed there. The cavities 165A, 165B, 165C are arranged in a support part 164 delimiting the three cavities 165A, 165B, 165C adjacent and adjoining each other. Thus the separation walls of the cavities 165A, 165B, 165C meet on a central part of the support part 164 so as to guide the different air flows in the direction of the tube 162.

Thus, each air flow thus generated is guided into the corresponding receiving cavity 165A, 165B, 165C to then recombine with the other air flows at the level of the tube 162.

It will be noted that in the context of the invention, each fan 18A, 18B, 18C, the corresponding receiving cavity 165A, 165B, 165C and the tube 162 together form a variable air flow generation system in order to generate a flow of variable air at said housing 13A, 13B, 13C along the air flow path of the corresponding capsule 20A, 20B, 20C.

Likewise, such variable air flow generation systems each form, in accordance with the invention, a variable diffusion generation system capable of generating a variable diffusion of the compound through the outlet face 22 of the capsule 20A, 20B, 20C housed in the corresponding housing 13A, 13B, 13C.

It will be noted that according to a variant of the invention, instead of such a configuration of the variable diffusion generation systems, each variable diffusion generation system may comprise a heating system, such as a heating resistor, adapted to heat the corresponding capsule, and therefore the compound it contains, in order to induce the thermal diffusion of said compound. According to this variant of the invention, the compound can be supplied in a form other than that of granules.

In the context of this variant of the invention, the diffusion generation systems can also include a respective or common fan in order to facilitate the diffusion of the compound.

The control circuit 15, the power source and the speakers 19 are arranged in the body 12 housed at a bottom of the body 12 opposite the cover 12A. Thus, in a usual configuration of the transmitting device, in which the cover is oriented upwards, the control circuit 15, the power source and the speakers 19 are arranged under the housing assembly 13A, 13B, 13C/ aeraulic circuit/ fans 18A, 18B, 18C.

The control circuit 15 is connected to the fans 18A, 18B, 18C and the speakers 19 and is configured to control them. Thus and in particular, the control circuit 15 is configured to vary the air flow generated by each fan 18A, 18B, 18C in order to vary the proportion of compounds in the olfactory composition emitted by the emission device 10. The control circuit 15 advantageously includes a wireless connection system, such as a Bluetooth or Wifi connection system. Such a wireless connection system allows the user to connect to the transmitting device 10 in order to control it and control the different olfactory, visual and auditory stimuli that it emits. In particular, as shown in the , the user can program the emission of a given olfactory composition in association with music and lighting. Indeed, we can see on the that, via a dedicated application, the user can define a program 31 for which the emission of a predefined olfactory composition is planned, here an olfactory composition comprising the following compounds 32: 45% of a compound 32 corresponding to grapes, 55% of a compound 32 corresponding to cherries, and 0% of a compound 32 corresponding to lotus. The application also presents a control button 33 for the lighting system of the transmitting device 10, and a control button 34 for music broadcasting in order to play a song, here "singing bird" by the music broadcasting system .

It will be noted that the control circuit corresponds in the present embodiment to an electronic circuit equipped with a processor which is able to manage the different elements of the emission device 10, such as the fans 18A, 18B, 18C, in function of the user's commands received, for example, by means of the mobile terminal 20.

Regarding the emission of the olfactory composition itself, as shown in the , the cover 11 has an emission chimney 14A extending from the opening 14 towards the body 12. The emission chimney 14A is arranged to connect with one end of the tube 162 which is opposite the receiving cavities 165A, 165B, 165C so as to fluidly connect the opening 14 to the receiving cavities 165A, 165B, 165C. In this way, the air flows come together, after passing through the capsules 20A, 20B, 20C and through the receiving cavities 165A, 165B, 165C, at the level of the tube 162 in which the different compounds mix to form the olfactory composition and be emitted through the opening 14.

In order to better understand the principle of emission of each of the compounds of the olfactory composition, Figures 5A and 5B both illustrate a capsule 20A, 20B, 20C according to the invention by respectively showing a three-quarter view of the face of outlet, that is to say that which is opposite the fan when the capsule is arranged in the housing 13A, 13B, 13C and a three-quarter view of the inlet face with the capsule cover removed to show the compound in the form of granules it contains. In the present embodiment, the capsule has a frustoconical shape with a collar at the level of the entry face 21A, 21B, 21C in order to abut on the cover 12A when the capsule 20A, 20B, 20C is introduced into the corresponding housing 13A, 13B, 13C. The inlet face 21A, 21B, 21C and the outlet face 22 are both circular in shape.

As shown in Figures 1B and 5A, the inlet face 21A, 21B, 21C and the outlet face 22 of the capsule are each perforated. The entrance face 21A, 21B, 22C of the capsule 20A thus has a plurality of circular openings distributed along radii of the central face around a central circle devoid of opening. The openings have a diameter which increases with the distance from the central circle. The outlet face 22 has in its center the two complementary metal contacts 24. Around these two complementary metal contacts 24, the outlet face 22 has eight openings in an arc of a circle distributed over two circles, the outermost openings having a dimension more important than the most internal gills.

With such a perforation of the inlet face 21A, 21B, 21C and the outlet face 22, the capsule defines an air flow path between the inlet face 21A, 21B, 21C and the outlet face 22. This air flow path allows air circulation between the granules of the compound which is contained in the capsule 20A, 20B, 20C.

With regard to the complementary metallic contacts 24, the illustrates a detection circuit 25 equipping the capsule 20A, 20B, 20C at its output face 22 with on the left a bottom view which shows the two complementary metallic contacts 24 circular and on the right, a top view which shows the resistance 25A connecting these two complementary metal contacts 24 by through-vias, not shown. In this case, resistor 25A is a SMT type resistor (i.e. surface mounted component). The detection circuit is arranged at the bottom of the capsule 20A, 20B, 20C. It will be noted that such a detection circuit is, in the present embodiment, integrated by inclusion in the output face 22 of the capsule 20A, 20B, 20C. Alternatively, a simple housing can be provided, the output face then integrating secondary vias in order to allow the two complementary metal contacts 24 which it presents to be connected to two remote contacts provided on the output face

Concerning the compound as such, it is in the present embodiment provided in the form of solid granules 23. To be more precise, each compound can be obtained from pure natural extracts and/or essential oils. According to another possibility, one or more olfactory compounds can be synthesized. Thus, in particular, the olfactory compounds may include dimethylphenethyl butyrate. This ingredient is used as flavors and/or perfumes. From an organoleptic point of view, it brings a floral, herbaceous, fruity and/or green note.

In order to provide said compound in the form of solid granules, it can be included in an olfactory composition support in the form of granules and manufactured in any materials capable of being impregnated with a fragrance or perfume, i.e. i.e. the compound. Said support can be made of natural material such as clays but also of synthetic material such as polyacrylamides such as resins. Preferably, this material is a resin. According to this possibility, in one embodiment, the support compounds of the olfactory composition in the forms mentioned above are manufactured from thermosetting synthetic resins such as phenolic resins. They have good characteristics of dimensional stability, hardness and resistance to heat and corrosion. In particular, they are resistant to contact with weak acids and bases, hydrocarbons, petroleum products, alcohols, glycols, mineral oils and greases. Epoxy resins are also possible for such a support in the context of the invention.

Thus, with such a configuration of the capsules, the air flow generated by the fan 18A, 18B, 18C of the housing 13A, 13B, 13C will make it possible to diffuse and transport olfactory molecules of said compound in the direction of the opening in order to form the olfactory composition at the level of the tube 162 and allow its diffusion at the level of the opening 14.

In order to complete the description of the emission device 10, the illustrates functional elements, such as a power button 15A and a charging connector 15B, which have not been described. As we can see on the , the transmitting device includes a power button 15A in order to enable the transmitting device 10 to be turned on. This power button can also act as a pairing button for the device in order to enable its pairing , for example by means of a Bluetooth™ connection, with the mobile terminal 30. According to this possibility, a short press makes it possible to change the state of the transmitting device, it going from the running state to the stopped state or vice versa, a long press allows you to trigger the pairing mode of the transmitting device.

The 15B charging connector allows you to connect a transformer in order to recharge the power source when the latter is one or more accumulators or batteries. According to this possibility, in order to also allow operation on the mains, this 15B charging connector can also act as a power source.

It will be noted that in a usual configuration of the invention, the start button 15A and the charging connector 15B both equip the control circuit 15 and are thus connected to the integrated circuit of the latter.

There also makes it possible to show the three support feet 12A of the body 12 of the transmitting device 10 and which allow a stable position of the latter.

According to the invention, the device 10 for emitting an olfactory composition and at least one capsule 20A, 20B, 20C, preferably three capsules 20A, 20B, 20C, can form a kit for emitting olfactory compositions.

It should also be noted that a device for emitting an olfactory composition can implement a method for emitting an olfactory composition comprising the following step:
- generation of an air flow at least one housing 13A, 13B, 13C along the air flow path of at least one capsule, the air flow at each housing 13A , 13B, 13B and therefore at the level of each capsule 20A, 20B, 20C being chosen according to the olfactory composition to be emitted.

It will be noted that, in accordance with the invention, it can also include a step of emitting at least one other stimulus from among a sound stimulus and a visual stimulus.

There illustrates a detection circuit 25 according to a variant of the invention in which each variable diffusion generation system can comprise a supply circuit for a heating resistor, not shown, and a connector, not shown, connected to said circuit. power supply of a heating resistor and arranged in the housing being configured to connect with a complementary connector, not shown, of a capsule housed in said housing, the capsules intended to be housed in said housing having said heating resistor 26.

Such a heating resistor 26 allows good transmission of the heat generated by the heating resistor 26 to the compound, thus ensuring optimal thermal diffusion. It will be noted that in addition to such a heating resistor power supply circuit, each variable diffusion generation system can also include a fan, this fan can be dedicated to said variable diffusion generation system as well as a common fan between several or all of the variable diffusion generation systems.

It will be noted that if in the present embodiment three housings are provided and therefore three variable diffusion generation systems, it is of course possible to provide a different number without departing from the scope of the invention.

In addition to the description of the emission device 10 according to the invention and these different possibilities described above, according to a possibility compatible with the invention but which is not limited to the latter, the emission device can be configured to implement a process for emitting an olfactory composition making it possible to compensate for the difference in volatility of the different compounds which compose it.

Thus according to this possibility compatible with the invention, a first capsule 20A can comprise a compound of the top note type, a second capsule 20B comprise a compound of the heart note type and a third capsule 20C a compound of a base note type . The emission device 10 allows, during the step of emitting the olfactory composition, to emit an olfactory composition which presents a variation of the respective composition in the first, the second and the third compound over time to take into account of the difference in volatility between the first, second and third compounds.

The first compound therefore presents a greater volatility than the second compound which itself presents a greater volatility than the third compound. According to this possibility compatible with the invention, it is possible to compensate for this difference in volatility throughout the emission of the composition. Thus, the olfactory composition can present, initially a given composition, in a second step, the composition is corrected to increase the relative proportion of the first compound then in a third step, the composition can be corrected to increase the relative proportion of the second compound.

Of course, if in the context of the present presentation of this possibility compatible with the invention, there is provided a compound of the top note type, a compound of the heart note type and a compound of the base note type, such a possibility compatible with the inventor covers other configurations without going beyond the scope of this possibility. Thus, for example, two top note type compounds and one base note type compound can be provided; according to this possibility, the olfactory composition can have a composition which adapts over time to compensate for the greater volatility of the two compounds of the top note type vis-à-vis the compound of the base note type. Thus, such a possibility is particularly advantageous when one compound has greater volatility than another of the compounds in the olfactory composition.
