    [0001] FIELD OF THE INVENTION The present invention relates to a method of hair treatment using a particular aerosol device comprising a composition comprising at least one fatty substance, and also relates to the particular aerosol device. comprising the hair composition. There are so-called "shiny" products that apply in finishing care, that is to say on dried hair. These products are difficult to apply because if the amount applied is too large or poorly distributed, the hair usually has a touch and a bold visual appearance. There is therefore a need to develop a new hair treatment method that provides improved hair shine while achieving a natural look. The Applicant has surprisingly and advantageously found that the use of a treatment method using a device provided with a dispensing means comprising a body open at its two opposite axial ends and a cooperating part open at its two opposite axial ends. , at least partially defining a dispensing orifice, for dispensing a composition comprising at least one fatty substance, made it possible to obtain easily and quickly a shiny, supple and light hairstyle. The subject of the invention is, according to a first aspect of the invention, a hair treatment method comprising the application to the hair of a composition comprising at least one fatty substance by means of an aerosol device comprising: a container containing the composition and one or more propellants, the propellant (s) may be present in the composition or, in the container, separated (s) from the composition, a distribution means of said composition comprising: a body open at its two opposite axial ends, - a cooperating portion open at its two opposite axial ends, at least partially defining a dispensing orifice. This particular combination allows an easy application and a homogeneous, fine and light distribution of the hair composition on the hair, thus leading to a shine of the hairstyle with a natural result. The process according to the invention thus makes it possible to provide shine to the hair while at the same time providing flexibility, lightness and softness to the hair.
    [0002] The present invention also relates to an aerosol device comprising: a container containing: one or more propellants, and a composition comprising at least one ester of fatty acids and / or of fatty alcohols and at least one oil. non-silicone, the agent (s) propellant (s) may be present in the composition or, in the container, separated (s) of the composition, - a means of distribution of said composition comprising: - a body open to its two opposite axial ends, 10 - a cooperating portion open at its two opposite axial ends, at least partially defining a dispensing orifice.

    [0009] Among these polydialkylsiloxanes, mention may be made, without limitation, of the following commercial products: SILBIONE® oils of the 47 and 70 047 series or the MIRASIL® oils marketed by RHODIA, such as, for example, the 70 047 V 500 000 oil; the oils of the MIRASIL® series marketed by RHODIA; Oils of the 200 series of Dow Corning, such as DC200 having a viscosity of 60,000 mm 2 / s; - VISCASIL® oils from GENERAL ELECTRIC and some oils from SF series (SF 96, SF 18) from GENERAL ELECTRIC. Mention may also be made of polydimethylsiloxanes with dimethylsilanol end groups known under the name of dimethiconol (CTFA), such as the oils of the 48 series from the company RHODIA. In this class of polydialkylsiloxanes, mention may also be made of the products sold under the names "ABIL WAX® 9800 and 9801" by GOLDSCHMIDT, which are polydialkyl (C1-C20) siloxanes.

The substituted amino groups are, in particular, C1-C4 aminoalkyl groups; alkoxylated groups, such as the product sold under the name "Silicone Copolymer F-755" by SWS Silicones and Abil Wax® 2428, 2434 and 2440 by the company GOLDSCHMIDT. The fatty substances are advantageously chosen from 06-016 hydrocarbons, hydrocarbons containing more than 16 carbon atoms, triglycerides, fatty alcohols, fatty acid esters and / or fatty alcohol esters other than triglycerides, and silicones. or their mixtures. Preferably, the fatty substance or fats is or are chosen from liquid fatty substances, in particular from mineral oils, liquid fatty alcohols, esters of fatty acids and / or of liquid fatty alcohols, silicone oils, or their mixtures. Even more preferentially, the fatty substances are chosen from mineral oils, liquid fatty alcohols, and esters of fatty acids and / or liquid fatty alcohols, or mixtures thereof. According to a preferred embodiment, the composition comprises at least one ester of fatty acids and / or fatty alcohols, preferably liquid, and at least one non-silicone oil.
    [0012] When the propellant (s) is (are) present in the composition, the fatty substance (s) is (are) present in an amount ranging from 0.1% to 80% by weight, more preferably 2% by weight. to 60% by weight, and even more preferably from 5 to 30% relative to the total weight of the composition.
    [0013] The composition may also comprise one or more C2-4 monohydric alcohols. As monoalcohol (s) C2_4 usable (s) in the aerosol device of the invention, there may be mentioned ethanol or isopropanol, or more preferably ethanol. When present, the C 2 -C 4 monohydric alcohol (s) is or are preferably present in an amount of from 1 to 70% by weight, more preferably from 5 to 60% by weight, and even more preferably from 10 to 10% by weight. at 50% by weight relative to the total weight of the composition, when the agent (s) propellant (s) are present in the composition. The composition according to the invention may contain one or more additional organic solvents such as polyols such as glycerin, propylene glycol or polyethylene glycols. It can also contain water. Preferably the composition according to the invention contains less than 5% by weight of water relative to the total weight of the composition, when the agent (s) propellant (s) are present in the composition. Even more preferably it does not contain added water. The composition is then called anhydrous. The container of the device according to the invention also comprises one or more propellants. Examples of propellants for use in the aerosol device of the present invention are liquefied gases such as dimethyl ether, 1,1-difluoroethane, or C3-5 alkanes, such as propane, isopropane, n-butane, and the like. , isobutane, pentane, or compressed gases such as air, nitrogen, carbon dioxide, and mixtures thereof. Preferentially, mention may be made of C 3 -C 5 alkanes and in particular propane, n-butane and isobutane, and mixtures thereof. The agent (s) may be present in the composition or, alternatively, in the container containing the composition, but separated from the composition. The agent or agents are preferably present in the composition. When the propellant (s) are present in the composition, it is (are) or is preferably present in an amount ranging from 10 to 90% by weight, more preferably from 15 to 80% by weight. by weight, and even more preferably from 20 to 75% by weight relative to the total weight of the composition.
    [0014] The compositions defined in the invention may further contain one or more additives chosen from anionic, cationic, nonionic amphoteric or zwitterionic polymers, conditioners or fixatives, perfumes, dyes, protective filters, acids, bases. , nacres, glitter.
    [0015] These additives may be present in the composition according to the invention in an amount ranging from 0 to 20% by weight relative to the total weight of the composition, when the propellant (s) are present in the composition. . Those skilled in the art will take care to choose these optional additives and their amounts so that they do not adversely affect the properties of the compositions of the present invention. The compositions in accordance with the invention are packaged in an aerosol device comprising a container, also called a reservoir. The container is pressurized and comprises the composition to be delivered. The container containing the pressurized composition may be opaque or transparent. It may be made of glass, polymeric material or metal, optionally covered with a layer of protective varnish. As already mentioned above, the container contains both the propellant (s) and the other ingredients of the composition, in a single compartment, or alternatively in two compartments. According to this latter variant, the container may be constituted by an external aerosol can comprising an internal bag hermetically welded to a valve. The various ingredients of the composition are introduced into the inner bag and a propellant is introduced between the bag and the can at a pressure sufficient to release the product in the form of a spray. The container is equipped at its upper end with a valve sealing the system. On this valve, comes to adapt a dispensing means on which the user can press to cause the output of the product. This distribution means is also called diffuser. As indicated above, the dispensing means according to the invention comprises a body open at its two opposite axial ends and a cooperating part open at its two opposite axial ends, at least partially defining at least one dispensing orifice. In particular, the dispensing orifice is preferably defined between the body and the cooperating part but may, alternatively, be defined entirely by the cooperating part.
    [0016] Thanks to the device of the invention, a passage is formed through the dispensing means and more particularly through the body and the cooperating part, allowing an air flow to be established through the dispensing means when the product to be dispensed is emitted, which may be advantageous when the product is emitted in the form of a spray, by allowing a stream of air to be created through the dispensing means to accompany the product. spray flow. Furthermore, the passage through the dispensing means can be made with sufficient dimensions to allow, if desired, to introduce the finger or a lock of hair in this passage. This may facilitate the application of a product to the finger or lock of hair. The invention may also allow, if desired, to facilitate the production of an annular section dispensing orifice between the cooperating portion and the body, allowing the formation of a hollow spray. Alternatively, a plurality of dispensing orifices are formed between the body and the cooperating portion, for example for the purpose of dispensing the product in the form of several sprays or jets. The number of dispensing orifices may in particular be between, inclusive, terminals 2 and 80, preferably between 5 and 60. It may for example be equal to 10. For example, the dispensing orifices have a cross section greater than or equal to to 0.0025 mm 2, more preferably 0.006 mm 2 and are preferably spaced apart from one another (measured along a straight line between centers of the apertures) by a distance of more than 1 mm. In another variant, a plurality of dispensing orifices are entirely formed in the cooperating part. The orifices may be constructed in such a way that the jet leaving each orifice is swirling, in particular thanks to at least two swirling channels oriented tangentially about the axis of the orifice. The cooperating portion may have, in axial half-section, a U shape. The body may have two concentric mounting skirts between which the cooperating part is fixed. The body may comprise a crown on which the cooperating part engages, the ring being able to carry one or more reliefs defining with the cooperating part supply channels, in particular vortex channels, towards the dispensing orifice.
    [0017] The body may define a housing in which the cooperating portion is received, which is then referred to as a core. The dispensing orifice (s) can be opened at rest. By "at rest" it is necessary to understand before the cooperating part is exposed to the pressure of the product to be dispensed. Thus, in this case, the dispensing orifices are already formed and opened when the product is sent into the dispensing means for dispensing. In a variant, the dispensing orifice is formed at the moment of dispensing the product, for example by virtue of the elasticity of at least a portion of the body or of the cooperating part, which deforms under the pressure of the product. timing of the distribution. Thanks to the invention, in the case of spraying, the spray can be emitted with a relatively large flow, if desired, while having a relatively simple construction and reliable operation dispensing means. In particular, the dispensing orifice can be made with well-defined dimensions. In addition, the dispensing means may have an attractive aesthetic for the consumer. The body may have a first outwardly flaring surface, respectively converging outwardly, and the cooperating portion having a second surface, facing the first surface, outwardly diverging, respectively converging toward the outside. The first surface can be tapered. The second surface may be conical, of the same angle as the first surface or upper or lower angle.
    [0018] A different angle resulting in a narrowing of the space can lead to an acceleration of the jet before its exit, which may be interesting in the context of a spray. The dispensing orifice may be single or not and may have an annular shape or not. The dispensing orifice may have a constant width in the circumferential direction. The dispensing orifices may be defined between two concentric surfaces of revolution, for example cylindrical of revolution. The distribution orifices may be axially symmetrical, preferably rotationally symmetrical, around the distribution axis in particular. The distribution axis is defined by the general direction towards which the product is distributed by the dispensing means.
    [0019] When the dispensing means has a plurality of dispensing orifices, they preferably have the following characteristics. Their cross section is advantageously a disk. They are preferably of cylindrical shape or of approximately cylindrical shape.
    [0020] The depth of each orifice is advantageously between 0.5 and 2 mm. A long length makes it possible to create an individual spray with a reduced cone to create a tubular effect with a consequent number of orifices. A reduced length allows a very wide individual spray and widens even more the application surface of the multi-orifice diffuser.
    [0021] The sum of the cross sections of the orifices of the ring is preferably chosen to be close to the surface of the orifice of the nozzle. With the same valve, different types of spray can be obtained by choosing the number and the section of the orifices. For example, it is possible to use a dispensing means according to the invention provided with 80 orifices of 0.005 mm 2 to obtain a soft mist or a dispensing means according to the invention provided with orifices of 0.1 mm 2 to obtain a powerful spray. The orifices can be distributed in different ways. They may be equidistant on the periphery of the ring, equidistant from each other over a portion of the ring, distributed in equidistant groups composed of several equidistant orifices. It is possible to create a ring completely supporting the dispensing orifices which may be cylindrical. In this configuration, small vortex orifices can be made with a different design of the inner and outer rings to allow the creation of a ring which will have the mission of creating the "centerpost" function at the rear. The cooperating portion is preferably reported, which facilitates its manufacture and that of the body. In a variant, the cooperating portion is molded in one piece with the body, in particular in the case of dispensing a foam, the dispensing orifice then having a larger cross-section than in the case of spraying. a spray. The space between the body and the cooperating part is fed by at least one supply channel whose section is preferably greater than that of the dispensing orifice, which facilitates the filling of this space before the product sort through the dispensing orifice.
    [0022] A product distribution chamber may advantageously be provided between the cooperating portion and the body upstream of the dispensing orifice. This can facilitate the emission of a homogeneous spray, in particular. The product supply channel may open into this chamber, which preferably has an annular shape. Its width, which corresponds to the gap 30 between the cooperating portion and the body, is preferably greater than the maximum width of the passage through which the distribution chamber communicates with the dispensing orifice. At least one of the body and the cooperating portion, preferably the body, may have at least one centering relief of the cooperating portion relative to the body, and preferably at least ten, preferably at least twenty, even better at minus forty. These reliefs can come to the edge of the part in which they are made so as to generate a multitude of orifices through which the product jets emerge, the centering reliefs being in particular oriented parallel to the distribution axis or obliquely in the same circumferential direction about the axis, possibly further defining between them sectional narrowing leading to an acceleration of the jet of product. This or these reliefs are preferably set back from the dispensing orifice when one seeks to generate a spray in the form of a single jet. The reliefs may be made on the body, being for example in the form of axial ribs evenly distributed over the entire surface of the body facing the cooperating portion.
    [0023] The centering reliefs may possibly ensure by themselves the maintenance of the cooperating part on the body. Alternatively, the cooperating portion is fixed on the body elsewhere than at the level of the centering reliefs, the centering reliefs in this case may or may not have a function of maintaining the cooperating portion on the body. Preferably, the cooperating portion is fixed relative to the body. Alternatively, the cooperating portion is adjustably attached relative to the body, for example to allow the user to adjust the width of the dispensing orifice or to close it when not in use, for example screwing it a quarter turn, this screwing accompanied by an axial displacement of the cooperating portion relative to the body. The cooperating portion may be flush with the front end of the body so as to generate a spray of axis substantially parallel to the axis of the cooperating portion. The cooperating portion may protrude axially from the front end of the body by a value of between 0.01 and 1 mm, better still between 0.01 and 0.5 mm. The spray can then be divergent towards the axis of the cooperating part. The curbing portion may be axially recessed from the front end of the body 25 by a value of between 0.01 and 1 mm, more preferably between 0.01 and 0.5 mm. The spray can then be convergent towards the axis of the cooperating part. The invention makes it easy to produce, if desired, a circular inner contour dispensing orifice. The inside diameter of the passageway formed through the dispensing means is, for example, greater than or equal to 10 mm, more preferably 15 mm, 20 or 30 mm. When the passage is not of circular section, the "inside diameter" designates that of the largest circle inscribed in this passage. The dispensing means may comprise at least two housings and two cooperating parts arranged in the housing and each defining with the body, at rest, a dispensing orifice according to the invention. The distribution axes may then be parallel or not, secant or not, for example converge towards one another.

Ive cut an example of dispensing means according to the configuration of Figure 14.
    [0027] In the drawing, the actual proportions of the different constituent elements have not always been respected, for the sake of clarity. The dispensing means 1 shown in FIGS. 1 to 3 is intended to equip a container (not shown) provided with a hollow valve stem or pump, through which the product to be dispensed contained in the container is conveyed to the dispensing means. 1. The container may in particular be a pressurized container of the aerosol canister type, containing a propellant such as for example compressed air or a liquefied gas. The container may be equipped with a valve and the valve opening may be effected for example by depressing the hollow stem or alternatively by tilting thereof. When the container is equipped with a pump, the pump can be actuated for example by depressing the hollow rod along its longitudinal axis. The dispensing means 1 comprises a body 3, which can be made monolithically by molding in one piece or have several elements made separately and assembled. The dispensing means 1 may comprise, as can be seen in FIG. 2, a housing 6 intended to cooperate with the hollow rod to allow the product delivered by the latter to gain a supply channel 7 which opens into a housing 8 The housing 6 has a dimension adapted to the outer diameter of the rod, so as to obtain a sealed mounting of the rod in the housing 6, so that the product delivered by the rod passes entirely into the channel of 7. The latter is for example coaxial with the container stem but could be oriented differently and comprise for example several differently oriented portions. A cooperating part 10, hereinafter referred to as a core when it is internal to the body, is fixed in the housing 8 and defines for example with the body 3 a dispensing orifice 12 of annular section, as illustrated. By "annular section" is meant within the meaning of the present invention any section following a closed contour, that this contour is circular, elliptical, polygonal or other.
    [0028] The core 10 is traversed axially through an opening 90 whose inner diameter D may be relatively large, for example greater than or equal to 10 mm, more preferably 15, 20 or 30 mm. The opening 90 contributes to give the dispensing means a particularly aesthetic appearance. In addition, the opening 90 may allow air to flow through the dispensing means under the effect of driving a spray from the dispensing orifice 12. This may help to increase the range. spray and can increase the freshness effect provided by it, if any. The opening 90 may also allow to introduce through the dispensing means a finger or a lock of hair, which can be used to apply a product in a single gesture on the entire circumference of the element introduced through the means of distribution. This can be an advantage to apply for example an antiseptic or care product on a finger or treat a lock of hair. The distribution axis Z may be perpendicular to the longitudinal axis X of the container on which the dispensing means is mounted, as illustrated.
    [0029] The dispensing means 1 comprises a base 92 which defines a surface 4 on which the user can press to cause dispensing. The base 92 may be extended inferiorly by a trim skirt 93, which covers the top of the container. The housing 8 which receives the core 10 is defined by a ring 94 of axis Z, the bottom side of which joins the base 92. The feed channel 7 passes through the base 92 and ends in the housing 8 at a distance from the axial ends , along the Z axis, of the ring 94, preferably being closer to the rear end 94a than the front end 94b, as shown in Figure 2. The body 3 may have, as illustrated, a shoulder 95 near the rear end 94a, against which may come, if necessary, in axial abutment the core 10 at the end of its assembly. The core 10 and the housing 8 may have annular surfaces 96 and 97, in sealed contact, to close the space formed between the core 10 and the body 3 behind the supply channel 7.
    [0030] Preferably, the circumferential width of the dispensing orifice 12 around the spraying direction Z is constant. It is not beyond the scope of the present invention when this width I varies, for example so as to take account of the possibly non-uniform loss of load experienced by the flow of the product upstream of the dispensing orifice 12. Nonuniform charge results for example from the geometry of the space between the core and the body, especially the presence of angles or crossings. By varying the width I, it can be made that the product can go out more easily where this pressure drop is greatest, if one tries to have a spray as homogeneous as possible. The width I of the dispensing orifice is for example between 0.01 and 2 mm.
    [0031] The core 10 may be attached in various ways to the body 3. In the example illustrated in FIGS. 1 to 3, the core 10 is frictionally retained on the body 3. In the example illustrated, the core 10 is made separately from the body 3 and attached thereto. The core 10 may be made of the same thermoplastic material as the body 3 or alternatively of a different thermoplastic material. It is also possible to use the core 10 to make a metallic material. Axial ribs 38 are formed on the inner circumference of the housing 8, as can be seen in FIGS. 1 and 3 in particular, in order to center the core 10 in the housing 8. The centering reliefs 38 may be, as illustrated in FIGS. 12A to 10 12C, parallel or oblique in the circumferential direction to the Z axis, or curves. Each relief 38 may have, when viewed in plan view, a polygonal contour, in particular rectangular or trapezoidal, or flared shape in the direction of the dispensing edge. Two centering reliefs 38 may define between them a narrowing 39 near the dispensing orifice so as to accelerate the fluid by venturi effect. The number of centering reliefs 38 is preferably at least 10, more preferably 20, even better 40. The gap 22 formed between the core 10 and the body 3 can have the configuration shown schematically in FIG. on the dispensing orifice 12 by an annular end portion 22c formed between two surfaces 3a and 10a, cylindrical of revolution about the axis Z.
    [0032] The end wall 22c is connected to a proximal portion 22a by an inclined intermediate portion 22b formed between facing surfaces 3b and 10b. The centering reliefs 38 extend in the proximal portion 22a. The latter is supplied with product by the distribution chamber 22d. When the user actuates the dispensing means 1, the product gains through the supply channel 7 the space 22 between the core 10 and the body 3 and can be delivered in the form of a spray through the orifice In the example of FIGS. 1 to 3, the spray is angularly continuous around the distribution axis, due to the absence of contact between the core 10 and the body 3 at the dispensing orifice 12. Indeed, the zone or zones of support between the core 10 and the body 3 are, for example, as illustrated, set back from the dispensing orifice 12 by a distance (measured along the Z axis of distribution) of at least 0.5 mm. The spray may be angularly discontinuous around the distribution axis, by the presence, particularly at the reliefs 38, of contact between the core 10 and the body 3 at the outlet of the product.
    [0033] Preferably, the cross section of the feed channel 7 is greater than the section of the dispensing orifice 12, so as to allow rapid filling with the product of the space upstream of the dispensing orifice. , which can contribute to the formation of a homogeneous spray from the beginning of the spray.
    [0034] The distribution chamber 22d arranged upstream of the space 22a in which the centering reliefs 38 extend receives the product delivered by the supply channel 7. The width w of the distribution chamber 22d is greater than that of the distribution chamber 22d. the end portion 22c which opens on the dispensing orifice 12. The distribution chamber 22d improves the distribution of the product before the latter 10 gains the narrower portions of the passage through which the product is evacuated. FIGS. 4B and 4C illustrate various other examples of possible configurations for the space 22 formed between the core 10 and the body 3 for the circulation of the product to the dispensing orifice. In the example of FIG. 4B, the space 22 formed between the core and the body 15 comprises a proximal portion 22a in which the centering reliefs 38 of the core 10 extend relative to the body 3, extended by an intermediate portion 22b. which makes an angle with the direction Z of spraying, for example a re-entrant angle. This intermediate portion 22b may be connected to an end portion 22c, which opens out to the dispensing orifice 12, this end portion being for example, as illustrated, defined between two surfaces 3a and 10a, cylindrical of revolution, parallel to the direction The variant of FIG. 4B does not have a distribution chamber. In the variant of FIG. 4C, the terminal portion 22c communicates directly with that 22a in which the centering reliefs 38 extend. The end portion 22c is, for example, at an angle to the distribution direction Z. Thus, in half-section Axially, the axis Z1 of the orifice 12 is for example convergent, as illustrated. In the variant of FIG. 4D, the cooperating part 10 is external to the body 3. The cooperating part 10 is fixed on the body 3 so as to arrange therewith the distribution chamber 22d, facing the supply channel 7 The portions 22a, 22b and 22c make it possible to convey the product to the dispensing orifice 12.
    [0035] The feed channel 7 opens for example into the distribution chamber 22d by a portion oriented parallel to the distribution axis Z. Centering reliefs 38 are formed for example on the body 3. The cooperating part 10 can be realized as illustrated, with an annular lip 39 which partially delimits the distribution chamber 22d and forms a narrowing 47 of section between the chamber 22d and the portion 22a.
    [0036] FIG. 4E illustrates the possibility of having an angle between axis Z2, in axial half-section, of orifice 12 and the distribution axis, which is divergent. In the variant of FIG. 4F, the possibility of having no angle between the distribution axis and the Z axis of the cooperating portion 10 is illustrated. The supply channel 7 opens for example onto a chamber of FIG. distribution 22d. The product is conveyed to the dispensing orifice 12 via channels 22 comprising the reliefs 38. The reliefs 38 extend to the edge of the dispensing orifice 12 and define a plurality of orifices for delivering the product under the form of a plurality of jets. The invention is not limited to a dispensing head having a single dispensing orifice 12 made according to the invention. For example, there is illustrated in Figure 5 a dispensing head 1 which has two dispensing orifices 12. In the presence of several dispensing orifices, they can be distributed in many ways on the dispensing means. For example, the spraying axes 15 are parallel, or at an angle, being, for example, intersecting. FIGS. 7, 8A and 8B illustrate the possibility for the dispensing means to have a plurality of dispensing orifices 12 formed entirely in the core 10 in order to distribute the product in the form of several jets, for example. The dispensing orifices 12 may have many shapes when viewed along their transverse axis, in particular circular or triangular, as illustrated in FIGS. 8A and 8B. The dispensing orifices 12 may be drilled in the core 10, for example by laser drilling. The core 10 may have an axial half-section, as shown in FIG. 7, the shape of a U. The body 3 may comprise two concentric mounting skirts 41 which define between them a mounting space for the core 10, and comprise at its center a crown 43 serving to support the cooperating portion 10. The skirts 41 define with the ring 43 two annular channels 45 in which are placed the tabs of the U. The ring 43 may comprise for each orifice 12 two channels of supply 22 of the liquid to this orifice 12. During assembly, as illustrated in FIGS. 14 and 17, the core 10 can be pressed against the stud 43, the end face 48 of the crown 43 being in contact with the inner face 11 of the core 10. The legs of the U of the core 10 are fixed in the channels 45, the inner face 46 of the mounting skirts 41 being in contact with the face 13 of the core 10. The inner faces 14 of the legs of the U and the lateral surfaces 49 of the crown 43 may define between them the supply channels 22 of the liquid towards the dispensing orifice 35 12. The crown 43 may have, in particular in the form of indentations, on its outer face 48, supply channels 23 allowing the passage liquid from the supply ducts 22 to the dispensing orifice 12. The supply ducts 22 open upstream of the dispensing orifices 12, on the supply ducts 23 which lead to the dispensing orifice 12. 5 and 23, by their orientation with respect to the dispensing orifice, generate a vortex flow at the outlet of the dispensing orifice 12. This configuration is more particularly useful in the case of a carrier gas which does not is not liquefied. In a variant, the supply ducts 22 may be made in the form of indentations on the lateral surface 49 of the body and / or on the inner faces 14 of the core 10. In a variant that is not shown, the core 10 has, in particular in the form of imprints on its inner face 11, supply channels 23, the end face 48 of the crown 43 can be smooth. In a variant, the ring 43 is not circumferentially continuous and defines pads. The studs are placed upstream of the dispensing orifices 12 and may have, upstream of the dispensing orifices 12, the supply channels 22 and 23 as described above. In the variant of FIGS. 4F, 9 and 10, the dispensing orifices 12 are formed between the core 10 and the body 3, being for example distributed all around the spraying axis Z. The core 10 or the body 3 may have centering reliefs 38 which circumferentially delimit the dispensing orifices 12. The centering reliefs 38 may, as illustrated in FIGS. 12A to 12C, come to the edge of the core 10 over the entire periphery and define between them the distribution orifices 12. The number of dispensing orifices 12 is preferably at least 10, more preferably 20, more preferably 40. The cross section of a dispensing orifice 12 is, for example, greater than 0.003 mm 2. The dispensing orifices 12 are preferably spaced apart by a gap of at least 1 mm, which is the same as the pitch p between the centering reliefs. As illustrated in FIGS. 10A and 10B, the dispensing orifices 12 may be of polygonal cross-section, in particular triangular in cross-section.
    [0037] The core 10 may extend, as shown in Fig. 13A, recessed from the body by a value between 0.01 and 1 mm, more preferably between 0.01 and 0.5 mm. The body 3 overflows from the dispensing orifice and can generate a convergent spray. The core 10 may be, as shown in Figure 13B, flush with the body 3. The spray can then be straight.
    [0038] The core 10 may extend, as illustrated in FIG. 13C, forward with respect to the body 3 by a value of between 0 and 1 mm, better still between 0 and 0.5 mm. The spray can then be divergent. It is not beyond the scope of the present invention when an additional dispensing orifice 5 is present, for example by bringing back inside the core 10 a second core 50 which defines with the first core 10 a second dispensing orifice 51, coaxial with the first, as shown in Figure 6. A passage 90 remains formed through the dispensing means. The dispensing orifice may be fed by more than one product.
    [0039] The dispensing means may be fed with two products which are dispensed by separate dispensing orifices. The Z axis may be non-perpendicular to the axis of the container stem on which the dispensing means is mounted, as illustrated in FIG. 11. In this example, the Z axis is oriented upwards when the container is vertical with the dispensing means at the top. The feed channel 7 can be oriented substantially parallel to the distribution axis Z, at least for the portion that opens facing the cooperating portion 10. The latter can be made with an annular lip 39 which defines a sectional narrowing 47.
    [0040] The configuration may be similar to that of FIG. 4D except that the cooperating portion 10 is external to the body 3 in the example of FIG. 4D and internal in the example of FIG. 11. The dispensing means can be arranged to allow the mounting of a protective cover and include, where appropriate, an on / off system to prohibit the actuation of the device for a certain position of the dispensing means relative to the container or for a certain position a locking member of the dispensing means relative thereto. In non-illustrated variants, the dispensing orifice is formed between a body and a cooperating part, the body being radially internal with respect to the cooperating portion, the channel for feeding the product passing through the body. All the features described with reference to the figures can be found in such variants where the body is radially internal with respect to the cooperating part. The following example serves to illustrate the invention.
