    [0001] The present invention a device for dispensing a composition, comprising i) a dispensing head (1) intended to equip a container containing said composition, said device comprising: - a body ( 3) open at its two opposite axial ends, - a cooperating portion (10) open at its two opposite axial ends, defining at least partially at least one dispensing orifice (12), the cross section of the dispensing orifice being included between 0.05 mm 2 and 0.5 mm 2, ii) the anhydrous composition comprising, in particular in a physiologically acceptable medium, a) at least one oily phase comprising at least one volatile hydrocarbon oil, and b) at least one clay, and c) at least one deodorant active agent, and d) at least one propellant. The present invention also relates to a process for the cosmetic treatment of body odors and possibly human perspiration, which consists in applying to the surface of a keratin material a composition distributed by means of the dispensing device defined above. Deodorant / antiperspirant aerosols are particularly sought after by the consumer for their very good effectiveness, but they tend to bring tingling sensations or sometimes of perception of dryness which can hinder the user's comfort, particularly in people with sensitive skin or underarm shaving. In the aerosol devices proposed up to now for dispensing deodorant / antiperspirant products, many spray heads have been proposed at one or more dispensing ports. Many parameters are to be considered when designing a spray head. First of all, the spray generated must have the particle size suitable for the application. In this respect, the size of the droplets should not be too small or too large. Moreover, the spray generated must be delivered with the required flow rate and the spraying head must not oppose too much a loss of pressure to the circulation of the product. The shape of the spray must also correspond to the intended application and thus allow, depending on the case, to cover a more or less extensive surface. Finally, the spray head must be aesthetically attractive to the consumer, and its manufacture compatible with the requirements of large scale production. The application EP 1 052 023 A1 discloses a spray head having a dispensing orifice defined between a shutter having a frustoconical portion and the body of the head. The shutter opens by deformation of the frustoconical portion under the pressure of the product during dispensing. A conical and hollow spray is formed, at least in the vicinity of the head. The application WO 2011/065413 discloses various arrangements of spray heads in which a spray orifice is defined between a peripheral portion and a central portion, interconnected by bridges of material.
    [0002] The invention aims to provide an aerosol device with a dispensing head that is particularly suitable for spraying a deodorant or antiperspirant product without the disadvantages mentioned above in particular to avoid or substantially reduce the sensation of stinging or perception of drying The invention also aims to provide an aerosol device with a spray head that produces a totally original visual effect compared to what currently exists.
    [0003] The invention also aims to provide an aerosol device with a spray head providing a sensation to the application distinct sensations felt with the current devices.
    [0004] In addition, the spraying must be effective for the intended application. In particular, in the field of deodorants or antiperspirants, one seeks spray heads with which it is possible to reach, precisely, a given target.
    [0005] There is a need to increase the speed of application of a product by spraying without increasing the risk of clogging related to the drying of the sprayed product.
    [0006] The invention thus aims to further improve the known devices while allowing the use of manufacturing techniques whose cost is compatible with a large-scale distribution. The present invention a device for dispensing a composition, comprising i) a dispensing head (1) intended to equip a container containing said composition, said device comprising: - a body (3) open at its two opposite axial ends, - a cooperating part (10) open at its two opposite axial ends, defining at least partially at least one dispensing orifice (12), the cross section of the dispensing orifice being between 0.05 mm 2 and 0.5 mm 2, ii) the anhydrous composition comprising, in particular in a physiologically acceptable medium, a) at least one oily phase comprising at least one volatile hydrocarbon oil, and b) at least one clay, and c) at least one deodorant active agent, and d) at least one propellant. By "anhydrous" is meant in the sense of the invention, a composition whose total water content is less than 3.0% by weight relative to the total weight of the composition, and preferably whose water content is less than at 1% by weight relative to the total weight of the composition, or even free of water. For the purposes of the present invention, the term "physiologically acceptable medium" means a medium suitable for the administration of a composition topically. A physiologically acceptable medium is generally odorless, or uncomfortable, and is fully compatible with the topical route of administration. In the present case where the composition is intended to be administered topically, that is to say by surface application of the keratin material in question, such a medium is in particular considered physiologically acceptable when it does not generate tingling. tugging or redness unacceptable to the user. By "human keratin materials" is meant the skin (body, face, eye contour), hair, eyelashes, eyebrows, hair, nails, lips, mucous membranes. "Deodorant active" means any substance capable of diminishing, masking absorbing human body odor especially axillary odors. By "hydrocarbon oil" is meant an oil comprising mainly carbon and hydrogen atoms and optionally one or more functions selected from hydroxyl, ester, ether, carboxylic functions. By "oil" is meant a fatty substance that is liquid at ambient temperature (25 ° C.) and atmospheric pressure (760 mmHg, ie 105 Pa). The oil can be volatile or non-volatile.
    [0007] For the purposes of the invention, the term "volatile oil" means an oil capable of evaporating on contact with the skin or the keratin fiber in less than one hour at ambient temperature and atmospheric pressure. The volatile oils of the invention are volatile cosmetic oils which are liquid at ambient temperature and have a non-zero vapor pressure at ambient temperature and atmospheric pressure, in particular ranging from 0.13 Pa to 40,000 Pa (10-3). at 300 mm Hg), in particular ranging from 1.3 Pa to 13 000 Pa (0.01 to 100 mm Hg), and more particularly ranging from 1.3 Pa to 1300 Pa (0.01 to 10 mm Hg), Hg).
    [0008] 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.
    [0009] Thanks to the invention, a passage is formed through the dispensing head and more particularly through the body and the cooperating part, allowing a flow of air to be established through the head when the product to be dispensed is This can be advantageous when the product is emitted in the form of a spray, allowing a stream of air to be created through the head to accompany the flow of the spray. In addition, the dispensing head has an appearance that clearly contrasts with the usual aesthetics of known dispensing heads, and is particularly attractive to the consumer.
    [0010] Furthermore, the passage through the head can be made with dimensions sufficient 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.
    [0011] The invention may also allow, if desired, to facilitate the realization 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 greater than or equal to 10, more preferably 20, and even better 30. The dispensing orifices each have, for example, a cross section greater than or equal to 0.003 mm 2, better still 0.006 mm 2, and are preferably spaced between they (measured along a line between centers of gravity of the orifices) with 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 issuing from each orifice is swirling, in particular by virtue of at least two swirl 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 ring being able to carry one or more reliefs 40 defining with the cooperating part supply channels, in particular swirl channels, towards the dispensing orifice. The body can define a housing in which is received the cooperating part, which is then called core.
    [0012] 45 The dispensing orifice (s) may be open 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 head 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. Thanks to the invention, in the case of a spray, the spray can be emitted with a relatively large flow rate, if desired, while having a spray head of relatively simple construction and reliable operation. In particular, the dispensing orifice may be made with well-defined dimensions. In addition, the dispensing head can present 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 towards the outside. 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.
    [0013] 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.
    [0014] 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.
    [0015] The distribution orifice (s) may be axially symmetrical, preferably rotationally symmetrical, around the distribution axis in particular. The axis of distribution is defined by the general direction towards which the product is distributed by the head.
    [0016] The cooperating portion is preferably attached, which facilitates its manufacture and that of the body. In a variant, the cooperating part is molded in one piece with the body, in particular in the case of the dispensing of 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 45 through the dispensing orifice.
    [0017] A product distribution chamber may advantageously be formed 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 feed channel may open into this chamber, which preferably has an annular shape. Its width, which corresponds to the interval between the cooperating part and the body, is preferably greater than the maximum width of the passage through which the distribution chamber communicates with the dispensing orifice.
    [0018] 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 around the axis, possibly still possibly defining between them sectional narrowing leading to an acceleration of the product jet. 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. 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.
    [0019] 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 close it in the absence of use, for example in the screwing a quarter turn, this screwing accompanied by an axial displacement of the cooperating portion 35 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.
    [0020] The cooperating portion may protrude axially from the front end of the body by a value between 0 and 1 mm, more preferably between 0 and 0.5 mm. The spray can then be divergent towards the axis of the cooperating part. The winning portion may be axially recessed from the front end of the body 45 by a value of between 0 and 1 mm, more preferably between 0 and 0.5 mm. The spray can then be convergent towards the axis of the cooperating part. Advantageously, the dispensing orifice is of triangular cross section.
    [0021] More advantageously, the cooperating portion at least partially defines a plurality of dispensing orifices, the sum of the cross sections of the dispensing orifices being between 0.05 mm 2 and 0.5 mm 2, more advantageously the number of dispensing orifices. distribution orifices is greater than or equal to 5, preferably greater than or equal to 10. Preferably, the cross section of the dispensing orifices is between 0.03 mm 2 and 0.4 mm 2, and preferably between 0.05 mm2 and 0.4 mm2. The invention makes it easy to produce, if desired, a circular inner contour dispensing orifice. The inside diameter of the passageway formed through the head 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 head may comprise at least two housings and two cooperating parts disposed 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.
    [0022] Another object of the invention is, according to another of its aspects, a container equipped with a dispensing head according to the invention. The invention also relates to a device for dispensing a composition, said device comprising i) a dispensing head intended to equip a container containing said composition to be dispensed, the dispensing head comprising: a body open at its two axial ends opposed, a cooperating portion open at its two opposite axial ends, at least partially defining a dispensing orifice, and ii) the anhydrous composition comprising, in particular in a physiologically acceptable medium, a) at least one oily phase comprising at least one volatile hydrocarbon oil, and b) at least one clay, and c) at least one deodorant active agent d) at least one propellant.
    [0023] The invention also relates to a device for dispensing a composition, said device comprising: i) a dispensing head intended to equip a receptacle comprising a valve stem or a pump stem, the dispensing head comprising: a body 3029753 8 - a body provided with a connecting piece to the valve or pump stem, - an insert on the body, at least partially defining an annular section distribution orifice at rest or a plurality of distribution orifices distributed around a distribution axis (Z); The head being non-traversing along the distribution axis (Z); the body being closed along the distribution axis (Z) and said part being of annular shape, or the body having a through opening along the distribution axis (Z) and said part closing this opening; Ii) a composition comprising, in particular in a physiologically acceptable medium a) at least one oily phase comprising at least one volatile hydrocarbon oil, and b) at least one clay, and c) at least one deodorant active agent, and d) at least one less a propellant. The container may be a pressurized container, for example equipped with a hollow valve stem engaged in a housing of the head adapted to receive it.
    [0024] The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. , schematically in perspective, an exemplary dispensing head made according to the invention, before mounting the cooperating portion on the body of the head, - Figure 2 shows the dispensing head after mounting the cooperating part in FIG. 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 the body, FIG. to realize the dispensing head with two dispensing orifices according to the invention, - Figure 6 shows a front view of a dispensing head with concentric distribution orifices, - Figure 7 is an axial section of a manifold FIGS. 8A and 8B are various examples of configurations of the cooperating part of FIG. 7 in partial front view. FIG. 9 is a partial axial section of an alternative embodiment. 10A and 10B are front views according to X of different configuration examples according to FIG. 9, FIG. 11 is a view similar to FIG. 2 of a variant embodiment of FIG. 12A to 12C illustrate different examples of arrangements of the reliefs on the body, FIGS. 13A to 13C illustrate different examples of configurations of the cooperating part with respect to the body, FIG. partial axial of an alternative embodiment of the dispensing orifice, - 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 view in cut perspective of an exemplary dispensing head according to the configuration of FIG. 14.
    [0025] In the drawing, the actual respective proportions of the different constituent elements have not always been respected, for the sake of clarity. The dispensing head 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 head 1. The container may especially 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 rod or alternatively by tilting thereof. When the container is equipped with a pump, the actuation of the pump can be effected for example by depressing the hollow rod along its longitudinal axis. The head 1 comprises a body 3, which can be made monolithically by molding in one piece or comprise several elements made separately and assembled. The dispensing head 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 it 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 portions 40 oriented differently. A cooperating portion 10, hereinafter called the 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.
    [0026] For the purposes of the present invention, the term "annular section" means any section following a closed contour, whether this contour is circular, elliptical, polygonal or other.
    [0027] 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.
    [0028] The opening 90 contributes to giving the head a particularly aesthetic appearance. In addition, the opening 90 can allow air to circulate through the head under the effect of driving a spray emitted by the dispensing orifice 12. This can contribute to increasing the range of the spray and can increase the freshness effect brought by it, if any. The opening 90 may also allow to introduce through the head a finger or a lock of hair, which may allow to apply a single gesture a product on the entire circumference of the element introduced through the head. This may be an advantage in, for example, applying an antiseptic or care product to a finger or treating a lock of hair. The distribution axis Z may be perpendicular to the longitudinal axis X of the container on which the head is mounted, as illustrated.
    [0029] Head 1 has 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, whose lower side joins the base 92. The supply channel 7 passes through the base 92 and ends in the housing 8 at a distance from the axial ends, along axis Z, of crown 94, being preferably closer to rear end 94a than to front end 94b, as shown in FIG. 2. 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 width / 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 / varies, for example so as to take into account the possibly non-uniform pressure drop experienced by the flow of the product 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 /, it can be made that the product can get out more easily where this pressure drop is greatest, if one seeks to have a spray as homogeneous as possible. The width / distribution orifice is for example between 0.01 and 25 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.
    [0031] In the illustrated example, 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 in a different thermoplastic material. It is also possible to use the core 10 to make a metallic material.
    [0032] 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. 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 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, better 20, even better 40.
    [0033] The space 22 formed between the core 10 and the body 3 may have the configuration shown schematically in FIG. 4A, and lead to the dispensing orifice 12 by an annular end portion 22c formed between two surfaces 3a and 10a. cylindrical of revolution around the Z axis.
    [0034] 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. This latter is supplied with product by the distribution chamber 22d. When the user actuates the dispenser head 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 of distribution 12.
    [0035] 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. the bearing zone or zones between the core 10 and the body 3 are for example, as illustrated, set back from the distribution orifice 12 by a distance (measured along the distribution axis Z) at least 0.5 mm.
    [0036] 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.
    [0037] 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, this can contribute to the formation of a homogeneous spray from the beginning of the spray.
    [0038] 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 of the end portion 22c which opens onto the dispensing orifice 12. The distribution chamber 22d improves the distribution of the product before it reaches the narrower portions of the passage through which the product is evacuated.
    [0039] 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 25 comprises a proximal portion 22a in which the reliefs 38 of centering 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 on 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 end 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 axial section, the axis Z1 of the orifice 12 is for example convergent, as illustrated.
    [0040] 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 delivery channel 7. The portions 22a, 22b and 22c make it possible to convey the product to the dispensing orifice 12.
    [0041] The feed channel 7 opens for example into the distribution chamber 22d by a portion oriented parallel to the distribution axis Z.
    [0042] Centering reliefs 38 are made for example on the body 3. The cooperating portion 10 can be produced, 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.
    [0043] 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 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. The invention is not limited to a dispensing head having a single dispensing orifice 12 made according to 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 head. For example, the spray axes are parallel, or at an angle, being, for example, intersecting. FIGS. 7, 8A and 8B illustrate the possibility for the dispensing head 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.
    [0044] The core 10 may have the axial half-section, as illustrated in FIG. 7, in 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 ring 43 serving as a support for the cooperating portion 10. The skirts 41 define with the ring 43 two annular channels 45 40 in which are placed the legs of the U. The ring 43 may comprise for each orifice 12 two channels supplying liquid 22 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 ring 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 3029753 14 side surfaces 49 of the crown e 43 may define between them the supply channels 22 of the liquid to the dispensing orifice 12. The crown 43 may have, especially in the form of indentations, on its outer face 48, feed channels 23 allowing the passage the feed channels 22 open upstream of the dispensing orifices 12, on the feed channels 23 which lead to the dispensing orifice 12. In view of their orientation with respect to the dispensing orifice, the supply ducts 23 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 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 internal 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.
    [0045] 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.
    [0046] 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 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 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.
    [0047] The core 10 may extend, as illustrated in FIG. 13A, recessed from the body by a value of between 0 and 1 mm, more preferably between 0 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 45 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.
    [0048] 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 dispensing orifice 51. , coaxial with the first, as shown in Figure 6. A passage 90 5 remains formed through the dispensing head. The dispensing orifice may be fed by more than one product. The dispensing head 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 shaft on which the head is mounted, as shown in Figure 11. In this example, the Z axis is upwardly oriented when the container is vertical with the dispensing head 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 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.
    [0049] The dispensing head may be arranged to allow the mounting of a protective cover and include, if appropriate, an on / off system to prohibit the actuation of the device for a certain position of the dispensing head relative to the container or for a certain position of a locking element 30 of the dispensing head 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 part, 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 inner with respect to the cooperating portion.
