    [0001] The invention relates to a device for diffusing a fragrance such as a perfume. Document FR 2 958 854 discloses a fragrance diffuser comprising: two pourer-mounted stoppers each having a flow tube, a wafer of porous material mounted between the two pouring plugs, an outer ring provided, facing the wafer, at least one diffusion orifice of the fragrance. Each pourer plug also includes a flow hole that allows the passage of the fragrance in the porous material wafer, then outwardly of the device. The fragrance is for example contained in a bottle disposed above the diffuser. Although satisfactory this diffuser could however be simplified. For this purpose, the invention relates to a diffusion of a fragrance, characterized in that it comprises: two facing walls spaced apart from one another along a longitudinal axis so as to define between them a cavity which extends transversely to a peripheral wall provided with at least one opening for fragrance diffusion outside the device, said at least one opening placing the cavity in communication with the outside of the device, - several openings arranged in each of the two walls in view and which cross the relevant wall so as to allow, for a first of the two walls, the passage of the fragrance of a first zone in the cavity for the purpose of diffusing said fragrance to the outside of the device via said at least one diffusion opening, the first zone being adjacent to said first wall and separated from the cavity by this first wall and, for the second of the two walls, kings, the passage of the fragrance of the cavity to a second zone which is adjacent to said second wall and separated from the cavity by this second wall, - at least one duct which passes through each of the two opposite walls and extends into the zone adjacent to the wall concerned so as to put each zone adjacent to each wall in communication with the cavity, the said at least one duct arranged in the first wall being a return air duct, while the said at least one duct arranged in the second wall is a flow conduit of the fragrance from the cavity. In the device according to the invention, the fragrance (eg perfume) passes through the openings of the first wall (upper wall when the device is in the vertical operating position, the fragrance being contained in an upper flask turned over) and falls into the cavity (diffusion space) producing a drip. The drops fall by gravity on the second facing wall (lower wall also called collector) and flow through said at least one conduit connected to this wall in the second zone adjacent thereto (in particular in a lower bottle). This configuration of the device thus ensures, with the same means, both the diffusion of fragrance in the cavity and outside and the collection of drops to produce the drip below the device (especially in a lower bottle). The device according to the invention is therefore simpler than that of the prior art in which the diffusion and drip functions are dissociated. Neither is there any porous material to be installed in the cavity, which simplifies the device and makes it less expensive. Moreover, in the aforementioned prior art, to ensure the drip, very small holes (eg 0.2 to 0.5 mm) are required and they tend to clog in the presence of fatty products which go into the composition of fragrances (perfumes). With the device according to the invention, the multitude of openings in the facing walls limits this phenomenon. Unlike the device of the aforementioned prior art, the return air that compensates for the volume of fragrance flowing through the openings of the first wall comes from outside the device. This dissociates the air compensation in the bottle that dispenses its fragrance of the flow of this fragrance and, therefore, drip. In the prior art, the flasks communicate with each other by means of flow and air passage tubes. Thus, the pressure or the depression of one or the other of the flasks influences the operation of the drip (for example, when a balance of pressures must be established), which is not the case of the device according to the invention.
    [0002] According to other possible characteristics, taken separately or in combination with each other: the openings of one of the two facing walls are geometrically offset relative to the openings of the other wall; the fact that the openings of a wall are not vis-à-vis the openings of the facing wall avoids that the drops from the top openings do not fall on the lower openings, which could clog them; - At least some opening (s) arranged (s) in the two facing walls are each extended by a collar that protrudes into the cavity relative to the wall concerned; this arrangement makes it possible to prevent drops from clogging these openings of the second wall when they fall on it and flow over it; these openings of the second wall allow the evacuation of air in the lower bottle while the fragrance flows into said bottle; the device comprises a plurality of flow retardant elements of the fragrance which extend into the cavity so as to connect each two respective openings of the two facing walls, thus allowing the fragrance to be conveyed via each flow-retardant element an opening of the first wall to an opening of the second wall; - The flow retardant elements of the fragrance are formed of several tubes which extend into the cavity so that each tube connects two respective openings of the two walls opposite, thus allowing the fragrance to be conveyed via each tube an opening of the first wall to an opening of the second wall; in this configuration, the tubes retard the flow of fragrance drops, thus prolonging their stay in the cavity and therefore the diffusion phenomenon; each tube comprises, arranged along its length, at least two internal compartments separated from each other by a transverse partition, said tube being pierced along its length with a plurality of lateral orifices which allow the fragrance present in a compartment arranged near a first wall to exit, to flow along the outer face of said tube to reach the second wall and then said at least one duct formed in said second wall. This arrangement creates some sort of baffles for the flow of the fragrance by preventing a direct passage from one opening to another; the time of presence of the fragrance in the stagnation and flow cavity is thus increased, which makes it possible to prolong the diffusion effect and thus to improve it; - The flow retardant elements of the fragrance extend into the cavity along the longitudinal axis; - The device comprises, on either side of the two walls, in each zone adjacent to each wall, fastening means each for fixing to the device a neck of a bottle; each wall has a generally concave shape whose concavity is oriented towards the cavity and comprises a central region; said at least one duct is located in the central region; - The flow retardant elements of the fragrance are arranged around said at least one duct; - The device comprises one or more elements of absorbent material arranged on each of the two facing walls; this or these elements are able to absorb the liquid that falls on from the upper bottle to temporarily retain the liquid, thus avoiding the risk of sagging during the reversal of the device; the longitudinal axis is a vertical axis of the device. According to a second aspect, the invention also provides a system for diffusing a fragrance, characterized in that it comprises: - a diffusion device as briefly described above, - a first upper bottle having a first neck of which the opening is arranged vis-à-vis the first of the two walls facing said upper wall, a second lower bottle having a second neck whose opening is disposed vis-à-vis the second so-called lower wall, the first upper bottle comprising the fragrance which, by drip-like flow through the openings, causes, on the one hand, the diffusion of the fragrance into the cavity and outside the device via the at least one opening and, on the other hand, the drip into the second lower vial. This system has the same advantages and features as those mentioned in connection with the above-mentioned broadcast device and therefore will not be repeated here. Other features and advantages will become apparent from the following description, given solely by way of nonlimiting example and with reference to the accompanying drawings, in which: FIG. 1 is a schematic general view in axial section of FIG. a fragrance diffusion device according to a first embodiment of the invention; - Figure 2 is a bottom view of the device of Figure 1 returned; FIG. 3 is a schematic general view in axial section of a fragrance diffusion device according to a second embodiment of the invention; FIG. 4 is a diagrammatic view in axial section of a fragrance diffusion device that artificially integrates several variants of the embodiment of the device of FIG. 3; FIG. 5 is a diagrammatic view in axial section of a fragrance diffusion device according to a further alternative embodiment of the device of FIG. 1. As represented in FIG. 1 and designated by the general reference 25 denoted 10, a fragrance diffusion system comprises a fragrance diffusion device 20 and two bottles 12, 14 mounted head to tail which only the respective necks 12a, 14a are shown. A first upper bottle 12 containing the fragrance (eg a room fragrance) to be diffused is mounted in the inverted position above the device 30 with its neck 12a facing downwards. The device 20 comprises first fixing means 22 which are intended to fix the neck 12a to said device. These fixing means are for example made in the form of an internal thread 22a for screwing with the external thread 12b on the outer surface of the neck 12a. A second lower bottle 14 for recovering the non-diffused fragrance from the upper bottle 12 is mounted under the device 20 with its neck 14a facing upwards.
    [0003] The diffusion device 20 comprises second fixing means 24 which are intended to fix the neck 14a to said device. These fixing means are for example made in the form of an internal thread 24a for screwing with the external thread 14b on the outer surface of the neck 14a. Other fastening means such as snap-fastening can be envisaged.
    [0004] The system 10 and its device 20 and the two bottles are arranged vertically in Figure 1 so that the fragrance contained in the upper bottle 12 can flow by gravity. The device 20 comprises two parts, namely an upper part 26 and a lower part 28 disposed opposite and spaced from each other along a longitudinal axis L which here is oriented vertically. The two parts 26, 28 each comprise a wall 30, 32 disposed facing each other and defining between them, along the longitudinal axis L, a central cavity C. The walls 30, 32 extend transversely from their central region towards their periphery at which axially extends a wall 36, 38. The two axially extending walls 36, 38 of the parts 26, 28 extend in opposite directions. and away from the cavity C. The fastening means 22, 24 are arranged on the inner surface of these walls. Note that the neck 12a, 14a of each bottle, once attached to the device 20, abuts against a respective seal 31, J2 arranged in a recess of the outer face 30a, 32a of the transverse extension wall considered. As shown, each transverse wall 30, 32 has a generally concave shape whose concavity is oriented towards the cavity C. Each wall more particularly has a funnel shape converging towards the central region. Each piece 26, 28 generally presents a symmetry of axial revolution to a few details of implementation. Thus, the axial extension walls 36, 38 each have a substantially cylindrical shape conferring them a skirt shape. The device 20 also comprises at its periphery a peripheral wall 40 having a general shape of a ring surrounding the assembly formed by the two parts 26, 28 facing each other and the central separating cavity C. This peripheral wall 40 forms a part dressing and is fixed on each of the aforementioned sets for example by gluing, welding or other suitable means. The peripheral wall 40 is provided with at least one opening 42 for diffusing fragrance outside the device. Said at least one opening 42 is made in the region of the wall which is located around the cavity C so as to put this cavity in communication with the outside of the device. In practice, for a better distribution of the diffusion of the fragrance, several openings 42 are disposed around the perimeter of the peripheral wall 40 as shown in FIG. 1, in an equatorial region of the device. Each of the transverse extension walls 30, 32 comprises a plurality of through-openings, respectively denoted 01, 02, each of which communicates, with the cavity C, an external zone to the device, denoted respectively Z1, Z2, and adjacent to the wall. concerned 30, 32. As shown in Figure 1, each outer zone Z1, Z2 is an internal area at the neck of a bottle. FIG. 2 shows an example of the distribution of the openings 01 in the wall 30. The openings are arranged in series, each grouping several openings, the series being arranged in a radial arrangement. Other alternative configurations can be used (eg provision in concentric crowns ...). The openings disposed in the upper wall (here the openings 01 in the wall 30) are dimensioned to allow them to pass through fragrance drops G from the zone Z1 and fall inside the cavity as shown in Figure 1 The multitude of openings perforating the wall ensures a given diffusion capacity. This parameter depends on the intended applications.
    [0005] It will be noted that each opening 01, 02 is extended on the side of the inner face 30b, 32b of the wall 30, 32 by a collar respectively noted cl, c2 and which projects into the cavity relative to the wall concerned. This configuration prevents the openings from becoming clogged when the drops of fragrance fall on the wall 32 which acts as a collector (or on the wall 30 when the latter is in turn below and then acts as a collector) . The openings 01 and 02 of the two walls 30, 32 opposite are not vis-à-vis one of the other but offset transversely to reduce the risk of clogging in case of drop drops on the lower openings. Each of the transversely extending walls 30, 32 also comprises a duct 44, 46, respectively, arranged in the central region of the wall (at the bottom of the concavity) and passing through the latter so as to bring into communication the adjacent zone concerned ( Z1, Z2) with the cavity C. More particularly, each duct 44, 46 extends longitudinally (here vertically) in the adjacent area concerned in the manner of a chimney. The upper conduit 44 extends over a sufficient height so that the open end 44a of the upper conduit 44 is always above the level of the fragrance contained in the zone Z1. It is the same with the conduit 46 when the device is reversed and becomes an upper conduit. Each duct opens, at its end which is opposite the open end, at the inner face 30b, 32b of the relevant wall without projecting into the cavity. The openings 01 and 02 thus surround the ducts 44 and 46 respectively. The upper duct 44 acts as an air intake duct which takes air directly from the outside of the device via the openings 42 and not from the lower flask. . This arrangement is more efficient because it is less sensitive to pressure variations from one bottle to another. These pressure variations may be, for example, generated when the top vial is exposed to the sun behind a window and the bottom vial in the shade, or the opposite, or when the bottom vial is placed on a radiator then that the top one is exposed to a cold air current. Temperature changes affect pressures by the dilation effect of alcoholic bases that are present in perfumes. In the device according to the invention, the return air is in stable pressure since it comes from outside. It will be noted that the duct is dimensioned (in particular by its diameter) to allow a drop of fragrance in the cavity which is adapted to the number of openings of the wall and to their diameter and which is satisfactory in terms of diffusion power ( ability to diffuse odorant molecules into the atmosphere). Indeed, the flow rate and therefore the drip depends in particular on the ability of the device to take air.
    [0006] The lower duct 46 recovers the dropped drops on the inclined wall 32 and conveyed by gravity until duct. The conduit 46 thus ensures the flow of fragrance in the zone Z2 and in the lower bottle of the fragrance which has not been diffused. During operation of the fragrance diffusion system 10, the liquid (fragrance) present in the zone Z1 of the upper flask 12 returned passes through the openings 01, then forms drops G escaping from said openings. The drops drop by gravity inside the cavity over the entire height of the latter and explode upon reaching the bottom wall 32 of the collector. The diffusion of the fragrance is thus effected during the fall of the drops but mainly during the bursting of the drops on the wall 32. The diffusion takes place radially or transversely in the air which is present inside the cavity C (diffusion zone), then through the openings 42 to exit the device 20. The drip thus formed in the cavity creates somehow a suction of the liquid of the bottle 12 and therefore a depression in said bottle (effect of pumping). This depression is offset by the external air that enters the bottle through the air intake duct 44. All the liquid flowing in the form of drops in the cavity is not diffused in the latter. Indeed, a portion of the drops that reach the bottom wall 32 (arranged sloping towards the inlet 46a of the flow conduit 46) are collected on this wall without being diffused. These drops flow along the wall to the duct 46, penetrate and flow inside, then into the lower bottle 14, in the form of a dropper. When the liquid "not diffused" is passed in the lower bottle the diffusion phenomenon ends. The capacity of the lower vial is dimensioned so that the level of the liquid transferred into the vial is located below the free lower end 46b of the conduit.
    [0007] When there is no more liquid in the upper bottle 12 and the lower bottle 14 is filled (at least partially), the system is turned over: The lower bottle 14 becomes the upper bottle and vice versa, and the operating mode described above is repeated. It will be noted that the speed of flow of the liquid and therefore of the drip may depend on: - the calibration of the holes 01, - the viscosity of the perfume, - the calibration of the air intake 44. The collector walls 30 and 32 are inclined towards their central region (bottom concavity) in order to collect the liquid in the central conduit 46. This also allows the openings 02 present in the wall 32 (the same reasoning applies with the openings 01 present in the wall 30 when the system is turned over) are disposed at an altitude higher than that of a low point of the wall surrounding the duct 46 and around which liquid could accumulate. Such an arrangement considerably reduces the risk that liquid collected by the wall 32 will obstruct the openings 02 during system operation. FIG. 3 shows a fragrance diffusion system 60 according to a second embodiment of the invention. . This system 60 comprises a fragrance diffusion device 70 which differs mainly from the device 20 of FIG. 1 by the presence of tubes inside the cavity C. The identical elements with respect to FIGS. 1 and 2 will retain the same characteristics. references and will not be described again. The upper 72 and lower concave walls 74, inclined towards the inlet of each respective duct 44, 46, are also provided with openings O '1, O'2 passing through the wall concerned in its thickness, so as to allow forming and passing drops from the adjacent zone Z1, Z2 to the cavity.
    [0008] Several tubes 76 extend longitudinally inside the cavity, each between two openings 0'1 and 0'2 which are located vis-à-vis one another and which are connected by a tube. Each tube is for example inserted through its two opposite ends respectively in the two openings 0'1 and 0'2 in correspondence. Alternatively, the tubes can be attached to the relevant wall without being introduced into the openings. Each tube 76 is hollow and has a cylindrical wall 78 which is pierced with a plurality of lateral orifices 80 which communicate with the interior of the tube and the cavity. More particularly, the tube 76 is separated into two compartments or elongated chambers 82, 84, arranged one above the other and separated from each other by a transverse partition 86, for example at mid-height of the tube. The first compartment 82 communicates with the opening 0'1 and the second compartment 84 communicates with the opening 0'2. The lateral orifices 80 which are located lowest in the first compartment 82 are preferably arranged at a distance from the separating partition 86 so as to provide between them a space which can be filled with liquid (buffer volume). In operation, the liquid flows through the openings 0'1 and enters the first compartments 82 of each tube. The liquid accumulates by gravity in the aforementioned space until reaching the lowest holes 80 and out of the tubes by the latter. If the volume of liquid is larger, the compartment 82 fills further until it reaches the upper ports 80 and out through them. It will be noted that the section of the lateral orifices 80 and the internal section of the compartments 82, 84 is suitably sized for the purpose pursued. Thus, for example, if very small sections are selected for the side ports 80, the liquid can rise into the larger section compartment 82 and fill it up to the top. In this case, it is the section of the lateral orifices 80 which defines the rate of flow of the perfume into the cavity. The drops of liquid exiting the tubes flow along their outer face and, for some, diffuse in the cavity during this flow. Other drops that have not diffused along the outer face of the tubes 76, reach the lower wall 74 sloping (collector), slide along it in the direction of the central duct 46 and through to fall into the bottle inferior. The tubes 76 and the bottom wall 74 act as liquid collectors 5. Furthermore, the tubes 76 form baffles for the flow of liquid from the openings 0'1, thus slowing down this flow and therefore the phenomenon of drip. It follows that the passage time (flow) of the drops inside the cavity is increased, which makes it possible to increase the diffusion time and the diffusion capacity of the device. controlled by appropriately selecting the number of tubes 76 and their cross section. The two-compartment arrangement described above is easily cleanable in that the two compartments are accessible by their respective open ends. According to possible variants not shown: - the height of the compartments may be different from one compartment to another, the partition wall being arranged differently; the arrangement of the orifices may be different, for example in staggered rows; - The number of tubes and their distribution in the cavity may be different but still adapted to the number and arrangement of openings in the walls facing the device; more than two compartments may be arranged one above the other in order to increase the effect of baffles on the flow. Note that other means forming baffles for delaying the flow can alternatively be arranged in the cavity in relation or not with tubes such as drip tubes 76. FIG. 4 is a diagrammatic view in axial section of FIG. a fragrance diffusion device 100 which artificially incorporates several different types of liquid flow retardant elements and which are variants of the tubes of FIG. 3.
    [0009] For the sake of convenience, the different types are united in the same central cavity C, but a device 100 may very well comprise only one type of flow retardant element. The components identical to those of FIG. 3 retain the same references. In this variant, the elements have the function of retaining as long as possible in the cavity C (diffusion chamber) the liquid flowing from the upper flask. The drops flow along these elements and stay on even if the device is returned (limitation of sagging).
    [0010] These elongated members are mounted at their opposite upper and lower ends in the corresponding walls 72 and 74. These elongated members illustrated in FIG. 4 are: a single torpedo-shaped member 102 (pointed smooth cylinder at both ends thereof) A torpedo-shaped element 104 provided with pins 104a on its outer longitudinal surface; a torpedo-shaped element 106 around which is mounted a spiral spring 106a; a helical element 108.
    [0011] FIG. 5 illustrates a device 110 according to an alternative embodiment of the device of FIG. 1. In the device 110, elements of absorbent material 112, 114 (for example: felt pellet) are arranged on the walls 30, 32 (collectors ) to temporarily retain the liquid (perfume). This material captures the liquid and remains wet. When the absorbent material 114 of the bottom wall is saturated with liquid, the natural flow of liquid is directed towards the central duct 46. Thus, during the overturning of the device in use, the liquid is retained by the absorbent material and does not flood the cavity (strong limitation of the coulures).
    [0012] In addition, the liquid (perfume) is retained longer in the cavity by these elements of absorbent material (delaying effect of the elements), which contributes to improving the olfactory performance of the device.
