DETAILED DESCRIPTION OF THE INVENTION

[0033] With reference to FIG. 1, the diffusion device according to the invention is composed principally of a nomadic element 1 capable of being mounted on a fixed part 2, that is itself mounted on a reservoir 3.

[0034] This reservoir 3 contains a liquid product that consists of a cosmetic product, and more particularly a perfume or an eau de toilette.

[0035] This reservoir 3 has a neck 10 defining an upper opening wherein a porous body of the fixed part 2 of the diffusion device, thus called a fixed porous body 9, can be inserted. This fixed porous body 9 extends over the entire height of the reservoir 3 such that it can touch the bottom of the reservoir 3 to become impregnated with product, regardless of the product filling level in the reservoir 3.

[0036] This fixed porous body 9 is fitted into a base 8 of the fixed part 2, capable of being mounted on the neck 10 of the reservoir 3. A fret 7, of which the operation will be described later in the description, also forms part of the fixed part 2.

[0037] The nomadic element 1 itself consists mainly of a portable jewel 4 that a user can wear all day, of the pendant type, that diffuses the same perfume as that contained in the reservoir 3. For this, the nomadic element 1 also includes a porous body called the mobile porous body 5. This mobile porous body 5 can be impregnated with perfume when it is brought into contact with the fixed porous body 9, during perfume refill periods. This mobile porous body 5 diffuses perfume by evaporation all day long.

[0038] A crown 6 also forms part of the nomadic element 1, in order to support the mobile porous body 5 and to keep the latter at a distance from the jewel 4, such that the perfume present on the mobile porous body 5 does not come into contact with the structure of the jewel 4 so as not to alter it, in particular in terms of corrosion, for example.

[0039] In this FIG. 1, some parts of the nomadic element 1 and some part 2 can have variant shapes, the functions thereof remaining identical. These variants represented on the right are numbered with prime numbers, for more clarity.

[0040] In the embodiment presented here, the nomadic element 1 is therefore mainly composed of three annular shaped parts, namely a decorative structure 4 of the jewel type, a mobile porous body 5, and a crown 6. The jewel 4 is, for example, of an 0-ring shape.

[0041] In the first variant, the mobile porous body 5 is force-fitted all around the crown 6 and then the crown 6/mobile porous body 5 assembly is fitted inside the jewel 4. The crown 6 thus provides an aesthetic function, because it makes it possible to conceal the mobile porous body 5 when the user looks at the centre of the jewel 4.

[0042] In the second variant, the mobile porous body 5 is mounted inside the crown 6, then the crown 6/mobile porous body 5 assembly is mounted inside the jewel 4.

[0043] In both cases, the crown 6, 6 ensures the function thereof of supporting the mobile porous body 5, 5, and the function thereof to withdrawing the mobile porous body 5, 5 with respect to the jewel 4 to prevent any contact between them. For this, as illustrated in FIGS. 7, 8 and 9, the crown 6 includes an upper attachment lip 26 and a lower attachment lip 27 for the fixing thereof with the jewel 4.

[0044] In the first variant, the mobile porous body 5 is pressed against the peripheral wall of the crown 6, and finds itself positioned between these two lips 26, 27. These two lips 26, 27 have a radial extension greater than the thickness of the mobile porous body 5 such that they cover it entirely and such that the latter cannot touch the jewel 4. This radial extension is similar to a cantilever sized so as to keep a certain distance between the mobile porous body 5 and the jewel 4. The jewel 4 itself includes an annular hollow part wherein the crown 6 is inserted. This hollow part is sized so as to form a sufficiently large housing to avoid all contact with the mobile porous body 5.

[0045] In the second variant, the mobile porous body 5 is inside the crown 6, thus this crown acts as a barrier between the mobile porous body 5 and the jewel 4.

[0046] In both cases, the mobile porous body 5 must be accessible from inside the jewel 4 for the perfume refill thereof. Thus, in the first variant, the crown 6 has openings 23 regularly distributed around the entire periphery thereof. Portions of mobile porous bodies (5) are therefore accessible through the openings 23. The thickness of the mobile porous body 5 is sized so that the portions arranged facing the openings 23 do not project towards the inside of the nomadic element 1. Thus, when taking charge of the nomadic element 1, there is no risk of contact between the skin of a user's fingers and the portions of the mobile porous element 5, or between clothing and the portions of the mobile porous element 5. In the second variant, since the mobile porous body 5 is mounted inside the crown 6, it is directly accessible in the entirety thereof.

[0047] Below in the description, the first variant will be revisited by the figures. It must be noted that the second variant could have been selected in the same manner.

[0048] In FIG. 2, the nomadic element 1 is fully assembled. In the same way, the fixed part 2 is fully assembled and fixed on the neck 10 of the reservoir 3. This fixed part 2 has one single supply point. The nomadic element 1 is at a distance from this supply point and is ready to be refilled.

[0049] In FIG. 3, the nomadic element 1 is mounted on the single supply point of the fixed part 2 and is currently being refilled with perfume. In this FIG. 3, there is only one fixed part 2, with one single supply point, to refill one single nomadic element 1.

[0050] Alternatively, as illustrated in FIG. 4, it is possible to set up three fixed parts 2 on one single reservoir 3, each having one single supply point, so as to be able to refill three nomadic elements 1 simultaneously. In the example illustrated, there is one pendant and two earrings that can be refilled simultaneously, forming part of one single decoration of jewel 4.

[0051] Alternatively, it is also possible to provide a fixed part 2 with several supply points in order to be able to refill several nomadic elements 1 simultaneously starting from one single fixed part 2. In this case, either there is one single fixed porous body 9 inserted through one single neck 10 that is divided into several branches then providing several supply points, or there are several fixed porous bodies 9 projecting from the reservoir 3 then providing several supply points.

[0052] More specifically, as illustrated in FIG. 6, the fixed part 2 of the diffusion device includes an attachment base 8 on the reservoir 3. This base 8 includes a central sleeve 14 closed in the upper part by a cap 17 and open in the lower part. This sleeve 14 defines an inner housing for the fixed porous body 9. Indeed, the fixed porous body 9 is forced into this sleeve 14 and is in a compression state. More precisely, the fixed porous body 9 includes a head 12 inserted inside the housing as defined above, and from which extends a rod 11 sufficiently long to reach the bottom of the reservoir 3. The fixed porous body 9 is held in position in the housing thanks to compression of the head 12 thereof in the housing, and using an annular rim 18 formed on the inner surface of the sleeve 14, that retains the head 12 if it descended.

[0053] The peripheral wall of the sleeve 14 is perforated in the upper part by slits 21 through which decompressed projections 13 lead out from the fixed porous body 9. Indeed, since the latter is compressed, it tends to be swallowed inside the slits 21 in order to expand.

[0054] In the first variant illustrated in FIG. 1, the head 12 of the fixed porous body 9 has a regular surface before it is inserted into the sleeve 14, then this head is deformed by compression after insertion, leading to these projections 13 that are swallowed by the slits 21.

[0055] In the second variant illustrated in FIG. 1, the head 12 of the fixed porous body 9 has an irregular surface before it is inserted into the sleeve 14. Indeed, it already includes projections 13 cut in advance in the porous mass. These projections 13 are distributed regularly around the head 12, respecting the dimensions and distances of the slits 21 provided for this purpose in the sleeve 14 of the base 8, such that each projection 13 can penetrate inside a corresponding slit 21. These projections 13 are necessarily decompressed because no force is applied to them. This second variant does not prevent compression of the fixed porous body 9 inside the sleeve 14.

[0056] Revisiting FIG. 6, the base 8 includes a skirt 16 developing around the lower part of the sleeve 14. This skirt 16 includes means of fixing to the neck 10 of the reservoir 3. In this case, the skirt 16 has an annular return capable of engaging with an annular shoulder provided on the neck 10 of the reservoir 3, so as to ensure an elastic interlocking between the skirt 16 and the neck 10 of the reservoir 3.

[0057] When this fixed part 2 is thus mounted on the neck 10 of the reservoir 3, the fixed porous body 9 is automatically impregnated with perfume present inside the reservoir 3. Firstly, perfume enters the rod 11 and then goes up by capillarity to the head 12 of the fixed porous body 9. Thus, the projections 13 from the fixed porous body 9 coming out from the slits 21 of the base 8 are all impregnated with perfume. It is then sufficient to put the nomadic element 1 into place on the upper part of the sleeve 14, such that the nomadic element 1 surrounds all the slits 21 of the sleeve 14, as can be seen in FIG. 7. Thus, the projections 13 from the fixed porous body 9 impregnated with perfume, come into contact with the mobile porous body 5 that has dried out after a day of diffusion, or at least into contact with portions of the mobile porous body 5 accessible via the openings 23 in the crown. By capillarity, the perfume passes from the fixed porous body 9 to the mobile porous body 5.

[0058] Preferably, the user puts their jewel 4 into place on the base 8 in the evening at bedtime, such that the refill takes place during the night, and the jewel 4 will be once again ready for use and impregnated with perfume the next morning.

[0059] When there is no nomadic element 1 in place on the base 8, the slits 21 and the projections 13 from the fixed porous body 9 are exposed to open air. Consequently, the perfume is permanently diffused in ambient air from the fixed part 2. To prevent this diffusion, and that the tank 3 does not empty in this way, it is necessary to provide means of protection against the evaporation of the product.

[0060] As illustrated in FIGS. 5 and 6, these means of protection against the evaporation of the product consist of a fret 7 that is movable in translation against spring means between an upper protection position facing the slits 21 of the base and a lower position providing free access for the nomadic element to the slits 21 for the nomadic element 1.

[0061] In FIG. 5, the fret 7 is in the upper position and covers the entire upper part of the sleeve 14 entirely so as to form a barrier against the evaporation of perfume through the slits 21. Better still, the cap 17 of the sleeve 14 includes a peripheral rim 19 against which the fret 7 abuts in the upper position, to ensure complete sealing between the base 8 and the fret 7. Thus, when there is no nomadic element 1 in position on the fixed part 2, the base 8 is completely sealed and perfume cannot diffuse.

[0062] More precisely, the spring means of the fret 7 consist of flexible tabs 20 resting on the bottom of a groove 15 formed between the sleeve 14 and the skirt 16 of the base 8. These flexible tabs 20 can take the form of a coil spring, or can simply correspond to a plurality of tabs 20 capable of bending under the effect of a stress. Any tab shape can be considered.

[0063] In FIG. 6, the fret 7 is in the lower position with free access of the nomadic element 1 to the slits 21. Indeed, under the effect of a stress applied to the fret 7, the tabs 20 bend and the fret 7 translates towards the bottom of the groove 15 until it is entirely hidden inside the groove 15. The slits 21 with projections 13 from the fixed porous body 9 are thus exposed, and diffuse perfume.

[0064] In FIG. 8, the fret 7 is in the upper position since the nomadic element 1 is at a distance from the fixed part 2. No perfume diffusion is therefore achieved at the fixed part 2.

[0065] In FIG. 7, the user puts the nomadic element 1 into place on the base 8 of the fixed part 2. During placement, the jewel 4 will apply a force on the fret 7 and will drive it in translation towards the lower position thereof. The nomadic element 1 is then in position all around the upper part of the sleeve 14 of the base 8, and the fixed porous body 9 is in contact with the mobile porous body 5, the transfer of perfume by capillarity thus takes place, as described above.

[0066] The nomadic element 1 can remain in place around the sleeve 14 because it is sized such that it applies a radial and axial friction against the sleeve 14, which is sufficient to resist the return force of the flexible tabs 20 of the fret 7. Indeed, the inner diameter of the jewel 4 is almost identical to the outer diameter of the sleeve 14 such that the nomadic element 1 can be put into place on the sleeve 14 by applying a gentle force. Furthermore, the crown 6 of the nomadic element 1 includes a slightly convex shape at the junction thereof between the peripheral wall thereof and the upper and lower lips thereof, that come into position under the peripheral rim 19 of the cap 17 of the sleeve 14, thus making it possible to better keep the nomadic element 1 in position on the base 8.

[0067] FIG. 9 shows a first possible configuration of a crown 6 belonging to the nomadic element 1. As described above, this crown 6 includes openings 23 and an upper lip 26 and a lower lip 27. The radial extension of the lips 26, 27 is sufficient to cover the thickness of the mobile porous body 5.

[0068] It could also be considered to extend these lips 26, 27 by a protection shield 25 that completely surrounds the mobile porous body 5, as illustrated in FIG. 10, to form a protection cage. In this case, an interstice 28 is formed between the shield 25 and the lower lip 27 in order to make it possible for the mobile porous body 5 to be inserted in the volume defined between the shield 25 and the peripheral wall of the crown 6. In this case, the mobile porous body 5 is entirely hidden behind the shield 25. The jewel 4 is entirely protected from the mobile porous body 5.

[0069] When the mobile porous body 5 is replaced, the crown 6 of the nomadic element 1 attaches itself to the sleeve 14 of the fixed part 2, in order to be separated from the jewel 4, and that the replacement of the mobile porous body 5 can be done. For this, attachment tabs 29 are provided on the sleeve 14 of the base 8. These tabs 29 are illustrated in particular in FIGS. 11 and 16. More precisely, these tabs 29 extend tangentially from the external peripheral wall of the sleeve 14, and are all oriented in the same direction of rotation. Each tab 29 is placed between two adjacent slits 21. Each tab 29 is capable of penetrating inside an opening 23 in the crown 6 when the nomadic element 1 is in place on the fixed part 2 and the user rotates the nomadic element 1.

[0070] In FIGS. 12 and 13, the nomadic element 1 is simply put into place and pushed onto the sleeve 14, for a conventional refilling of perfume by capillarity.

[0071] If the user wishes to replace the mobile porous element, for example because it is too old, all they need to do is to rotate the mobile element 1 with respect to the base 8 as indicated by the arrows on FIGS. 14 and 15. Thanks to this rotation, the tabs 29 penetrate inside the openings 23 in the crown 6, and the latter is thus secured to the sleeve 14. The user can then remove the jewel 4 alone with respect to the base 8. The crown 6 and the mobile porous body 5 remain attached to the base 8. The user can then easily remove the mobile porous body 5 from the crown 6 and implement another one. To secure the jewel 4 to the crown 6 again, it is sufficient to carry out the opposite operation, in other words to insert the jewel 4 again on the sleeve 14 via an axial translation movement, then to rotate the jewel 4 with respect to the base 8 in the opposite direction such that the tabs 29 are withdrawn from the openings 23 of the crown 6, and the crown 6 is thus once again engaged inside the jewel 4. The nomadic element 1 can then be withdrawn again completely from the base 8.

[0072] The same applies during first use of the mobile porous body 5. Indeed, at the first use, the crown 6 is secured to the sleeve 14 as illustrated in FIGS. 14 and 15, with the mobile porous body 5. The user can then choose the jewel 4 they prefer, and then put it into position and push it onto the sleeve 14. It is thus sufficient for them to rotate the jewel 4 in the opposite direction of the arrows so as to withdraw the tabs 29 from the openings 23 of the crown 6. The crown 6 and the mobile porous body 5 are then engaged inside the jewel 4, and the user can withdraw the entire nomadic element 1 from the base 8.

[0073] When the tabs 29 are completely engaged in the openings 23, the crown 6 thus tends to deform radially. Indeed, the crown 6 is made from a material that has elastic properties making it possible for it to deform elastically. In this case, by continuing their rotational movement, the user will deform the peripheral wall of the ring 6 radially inwards, given the attachment made with the tabs 29. This radial deformation will generate an angular deformation of the upper and lower lips 26 and 27, that will tend to move towards each other to close on the mobile porous body 5.

[0074] Optionally, the upper and lower lips 26 and 27 of the crown 6 have zones of weakness at the junction thereof with the peripheral wall of the crown 6. These zones of weakness make it possible to bend the lips 26, 27 so as to fold them even closer to the mobile porous body 5, as is illustrated in FIG. 15.

[0075] When the two lips 26, 27 are folded back, it is much easier for the user to remove the jewel 4 from the crown 6, the latter being secured to the sleeve 14 via the tabs 29.

[0076] The configurations shown in the figures mentioned are only possible examples of the invention that are in no way limitative, on the contrary the invention includes all variants of shapes and designs within the reach of a person skilled in the art.
