专利说明:
[0001] The present invention relates to an aerosol device comprising a particular distribution means and a composition based on at least one fixing and / or at least one fixing polymer. a styling powder comprising at least one mineral compound that is insoluble in water, and a method for treating the hair, especially for shaping the hair and / or maintaining the hairstyle. Hair products for shaping and / or maintaining the hairstyle most common in the cosmetics market are spray compositions, such as lacquers and sprays. They consist essentially of an alcoholic or aqueous solution and one or more materials, generally polymeric resins, also called fixing components, whose function is to form welds between the hair, mixed with various cosmetic adjuvants. These products make it possible to secure and hold the hairstyle over time. However, in practice, these products are not entirely satisfactory, especially in terms of hairdressing result. The aerosol sprays conventionally used lead indeed to a fixed hairstyle, which gives a helmet effect, the hair being glued. There is therefore a need to develop a new aerosol device comprising a hair shaping composition that provides a good fixation of the hairstyle while obtaining a natural rendering. The Applicant has surprisingly and advantageously found that the use of 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 fixing polymer and / or at least one styling powder comprising at least one water-insoluble mineral compound, makes it possible to obtain easily and quickly a soft and light hairstyle. The subject of the invention is, according to a first aspect, an aerosol device comprising: a container containing: one or more propellants, and a composition comprising one or more fixing polymers and / or one or more powder (s) capping agent (s) comprising one or more water-insoluble inorganic compounds, the propellant (s) which may be present in the composition or, in the container, separated from the composition, - A dispensing means of said composition comprising: - a body open at its two opposite axial ends, 5 - a cooperating portion open at its two opposite axial ends, at least partially defining at least one 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 shaping of the hairstyle with a natural result. [0002] The composition according to the invention thus makes it possible to fix the hair properly, leading to satisfactory shaping and / or holding of the hairstyle, while at the same time giving suppleness, lightness and softness to the hair. The present invention also relates to a hair treatment method, in particular for shaping the hair and / or maintaining the hairstyle, comprising the use of the device as defined above.

When they are present, the 02-04 monohydric alcohol or alcohols is or are preferably present in an amount ranging from 1 to 70% by weight, more preferably from 5 to 60% by weight, and even more preferably from 10 to 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 glycerine, propylene glycol or polyethylene glycols. It can also contain water. [0015] 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 propellant (s) is (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 that can be used in the aerosol device of the present invention are liquefied gases such as dimethyl ether, chlorinated and / or fluorinated hydrocarbons such as 1,1-difluoroethane, or volatile hydrocarbons, such as in particular alkanes. C 3 -C 5, such as propane, isopropane, n-butane, isobutane, pentane, or compressed gases such as air, nitrogen, carbon dioxide, and mixtures thereof. Preferentially, there may be mentioned dimethyl ether and C3-5 alkanes and in particular propane, n-butane, 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. [0016] The agent (s) are preferably present in the composition. [0017] When the propellant (s) is 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 15% by weight. 80% by weight, and even more preferably 20 to 75% by weight relative to the total weight of the composition. [0018] The compositions defined in the invention may furthermore contain one or more additives chosen from silicones, fatty esters, fatty alcohols, anionic, cationic, nonionic, amphoteric or zwitterionic polymers other than the fixing polymers, perfumes and dyes. , protective UV filters, acids, bases, nacres, flakes. [0019] 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 according to the invention are packaged in an aerosol device comprising a container, also called a reservoir, and a dispensing means. The container is pressurized and comprises the composition to be delivered. The container 20 containing the pressurized composition may be opaque or transparent. It may be 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 last 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. [0020] The container is equipped at its upper end with a valve ensuring the sealing of 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. [0021] 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, defining at least partially at least one dispensing orifice. [0022] In particular, the dispensing orifice is preferably defined between the body and the cooperating portion but may alternatively be defined entirely by the cooperating portion. 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 a flow of air to be established through the dispensing means when the product 10 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 flow of the product. spray. 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 can facilitate the application of a product on 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, several dispensing orifices 20 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 2 and 80 inclusive, preferably between 5 and 60. It may for example be equal to 10. The dispensing orifices have for example each a cross section greater than or equal 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 centroids of the orifices) 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 so that the jet exiting each orifice is swirling, in particular by virtue of at least two swirling channels oriented tangentially about the axis of the orifice. The cooperating part 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 crown being able to carry one or more reliefs defining with the cooperating part supply channels, in particular vortex channels, towards the dispensing orifice. [0023] 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 5 to be dispensed. Thus, in this case, the or the dispensing orifices are already formed and open when the product is sent into the dispensing means to be dispensed. Alternatively, the dispensing orifice is formed at the time of dispensing the product, for example thanks to the elasticity of at least a portion of the body or the cooperating portion, which deforms under the pressure of the product at the time of dispensing. the distribution. [0024] Thanks to the invention, in the case of spraying, the spray can be emitted with a relatively high flow rate, if desired, while having a relatively simple construction and reliable operation distribution 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. [0025] 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 towards the outside. outside. The first surface can be tapered. The second surface may be conical, of the same angle as the first or upper or lower surface. A different angle resulting in a narrowing of the space can lead to an acceleration of the jet before its release, which can 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 or distribution orifices may be defined between two concentric, for example cylindrical, revolution surfaces 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 to which the product is dispensed by the dispensing means. When the dispensing means comprises 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. [0026] 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 5. 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 distribution means 10 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 10 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 it is possible to make small vortex orifices with a different design of the inner and outer rings to allow the creation of a ring whose mission is to create 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. [0027] 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 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 resulting in 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. [0028] 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 cooperating portion may be axially recessed from the front end of the body 30 by a value of between 0.01 and 1 mm, better still 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 mm or 23 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 housings and each defining with the body, at rest, a dispensing orifice according to the invention. The distribution axes can then be parallel or not, intersecting or not, for example converge towards each other. The dispensing orifice may be axial, in axial half-section, convergent or divergent with respect to the direction of spraying. [0029] The invention also relates to an aerosol device comprising: - a container containing: - one or more propellants, and - a composition comprising one or more fixing polymers and / or one or more styling powder (s) comprising one or more a plurality of water-insoluble inorganic compounds, the propellant (s) present in the composition or in the container separated from the composition, a dispensing means of said composition comprising a body, a cooperating part, in particular a core, defining with the body, at rest, at least one annular section distribution orifice. The invention also relates to an aerosol device comprising: a container comprising a valve or pump stem, containing one or more propellants, and a composition comprising one or more fixing polymers and / or one or more powder ( (s) styling (s) comprising one or more water-insoluble inorganic compounds, the propellant (s) present in the composition or, in the container, separated from the composition, - A dispensing means of said composition comprising: - a body provided with a connecting piece to the valve stem or pump, - an insert on the body, at least partially defining a particularly annular section distribution orifice to rest or several dispensing orifices 35 distributed around a distribution axis (Z), the dispensing means being non-traversing along the distribution axis (Z), the body being closed along the axis of distribution ion (Z) and said piece being in particular of annular shape, or the body having a through opening along the distribution axis (Z) and said piece closing this opening. The invention will be better understood on reading the following detailed description, nonlimiting exemplary embodiments thereof, and on examining the appended drawing, in which: FIG. schematically in perspective, an example of dispensing means made according to the invention, before mounting the cooperating portion on the body of the dispensing means, Figure 2 shows the dispensing means after mounting the cooperating part in the body 3 is a view similar to FIG. 1 with partial section, FIGS. 4A to 4F illustrate various arrangements, among others, of the cooperating portion and of the body, FIG. distribution with two dispensing orifices according to the invention, FIG. 6 is a front view of a distribution means with concentric distribution orifices, FIG. 7 is an axial section of a variant of FIG. 8A and 8B are different examples of configurations of the cooperating part of FIG. 7 in partial front view, FIG. 9 is a partial axial section of an embodiment variant of FIG. 10A and 10B are front views according to X of various configuration examples according to FIG. 9, FIG. 11 is a view similar to FIG. 2 of an alternative embodiment of the dispensing means, FIGS. FIGS. 12A to 12C illustrate various examples of arrangements of the reliefs on the body, FIGS. 13A to 13C illustrate various examples of configurations of the portion 35 cooperating with respect to the body, FIG. 14 is a partial axial section of a variant. Figure 15 is a section along XV of Figure 14, Figure 16 is an embodiment of the body according to Figure 14, and Figure 17 is a perspective view. ective cut off an example of distribution means according to the configuration of Figure 14. In the drawing, the actual respective proportions of the various 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. [0030] 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 of the body 3. 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. [0031] A cooperating portion 10, hereinafter called 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. [0032] 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. Opening 90 contributes to imparting a particularly aesthetic appearance to the dispensing means. In addition, the opening 90 may allow air to circulate through the dispensing means under the driving effect of a spray emitted by the dispensing orifice 12. This may contribute to increasing the range of the spray and can increase the freshness effect brought by it, if any. The opening 90 can also allow to introduce through the dispensing means 10 a finger or a lock of hair, which can be used to apply a single gesture a product 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 15 on which the dispensing means is mounted, as illustrated. 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. [0033] The housing 8 which receives the core 10 is defined by a crown 94 of axis Z, whose lower side joins the base 92. The feed channel 7 passes through the base 92 and ends in the housing 8 away from the axial ends , along the Z axis, of the ring gear 94, preferably being closer to the rear end 94a than to the front end 94b, as seen in FIG. [0034] 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 sealing contact, to close the space formed between the core 10 and the body 3 behind the feed channel 7. Preferably, the width I circumferential 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 pressure drop experienced by the product flow upstream of the dispensing orifice 12. Non-uniform pressure drop results for example from the geometry of the space between the core and the body, in particular 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. [0035] The width I of the dispensing orifice is, for example, between 0.01 and 2 mm. The core 10 can be fixed in various ways on the body 3. In the example illustrated in Figures 1 to 3, the core 10 is frictionally retained on the body 3. In the example shown, the core 10 is made separately of the body 3 and reported on it. 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 15 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 more preferably 40. The space 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. [0036] 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 3031437 28 are for example, as illustrated, set back from the distribution orifice 12 by a distance (measured along the axis Z distribution) of at least 0.5 mm. The spray may be angularly discontinuous around the distribution axis, by the presence, in particular at the level of the reliefs 38, of contact between the core 10 and the body 3 at the outlet of the product. 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. [0037] 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 15 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 20 has 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 can be connected to an end portion 22c, which opens onto 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 30, 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. [0038] 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 portion 10 may be carried out, as illustrated, with an annular lip 39 which partially delimits the distribution chamber 22d and makes it possible to form a narrowing 47 of section between the chamber 22d and the portion 22a. FIG. 4E illustrates the possibility of having an angle between the axis Z2, in axial half-section, of the orifice 12 and the distribution axis, which is divergent. In the variant of FIG. 4F, the possibility of not having any angle 10 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 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. [0039] The invention is not limited to a dispensing head having a single dispensing orifice 12 made in accordance with the invention. By way of example, FIG. 5 illustrates a dispensing head 1 which has two dispensing orifices 12. In the presence of a plurality of dispensing orifices, these may be distributed in multiple ways on the dispensing means. For example, the spraying axes 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 can 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 include in its center a ring 43 serving as a support for 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 supplying liquid 22 to this orifice 12. [0040] 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 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 5 10. The internal faces 14 of the legs of the U and the lateral surfaces 49 of the ring 43 may define between them the supply channels 22 of the liquid to the dispensing orifice 12. The ring 43 may have, in particular in the form of indentations, on its outer face 48, supply channels 23 allowing the passage of liquid supply channels 22 to the dispensing orifice 12. [0041] The supply ducts 22 open upstream of the dispensing orifices 12, on the supply ducts 23 which lead to the dispensing orifice 12. The supply ducts 23 generate, by their orientation with respect to the distribution orifice, a swirling flow output of the dispensing orifice 12. This configuration is particularly useful in the case of a carrier gas that is not liquefied. [0042] 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. [0043] 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 distribution orifices 12. The centering reliefs 38 may, as illustrated in FIGS. 12A to 12C, come to the edge of the core 10 all around the periphery and define between them the orifices of 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 3031437, the distribution orifices 12 may be of polygonal cross-section, in particular triangular in cross-section. The core 10 may extend, as shown in Figure 13A, recessed from the body by a value between 0.01 and 1 mm, better between 0.01 and 0.5 mm. The body 35 projects beyond 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. 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 is present, for example by bringing back inside the core 10 a second core 50 which defines with the first core 10 a second distribution orifice 51, coaxial to the first, as illustrated in Figure 6. A passage 90 remains 15 arranged through the dispensing means. The dispensing orifice may be fed by more than one product. The dispensing means can be fed by two products which are distributed 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 shown in FIG. 11. In this example, the Z axis is upwardly oriented 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 which opens facing the cooperating part 10. This latter can be made with an annular lip 39 which defines a narrowing of section 47. 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 inside in the example of FIG. 11.
