专利说明:

[0001] The present invention relates to a particular aerosol device comprising a cosmetic composition based on at least one sebum-absorbing powder, and its use for dry-washing and the cosmetic treatment of hair-raising agents. keratin materials, preferably human keratin fibers such as the hair. In the field of washing keratin materials, dry shampoos have existed for many years, either in a powdery form or in the form of an aerosol. They allow to eliminate the excess of sebum in a fast way without wetting the hair. They act by seizing the sebum by absorption thanks to powders chosen for their absorbing qualities of sebum. The powders employed may be of mineral, organic or synthetic origin and may be derivatives of wheat starch, rice and maize. In practice, the dry shampoos proposed are not entirely satisfactory, especially in terms of application and comfort. The aerosol sprays conventionally used generate a conical spray. This type of spray is not optimal for a localized application, especially at the root and is generally uncomfortable to the application because of the impact force quite important on the hair. There is therefore a need to develop a new aerosol device comprising a composition of a dry shampoo that provides comfort to the application. There is also a need to develop such a device that provides optimal cleaning activity and a contribution of volume to the hair. 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 at least one dispensing orifice for dispensing a composition comprising an absorbent sebum powder facilitated the application of the composition with a better dispersion and to offer more comfort to the application while providing the cleaning properties expected of a dry shampoo. This particular combination allows easy application and a homogeneous, fine and light distribution of the hair composition on the hair, thus leading to optimal absorption of sebum with a natural result. The composition according to the invention makes it possible to wash the hair properly while at the same time giving suppleness, lightness and softness to the hair.
[0002] In a first aspect, the subject of the invention is an aerosol device comprising: a container containing one or more propellants, and a composition comprising one or more sebum-absorbing powders having a sebum greater than or equal to 35 ml / 100 g, the propellant (s) that 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, - a cooperating portion open at its two opposite axial ends, at least partially defining at least one dispensing orifice. This particular combination makes it possible to offer comfort to the application by limiting the force of impact of the spray on the hair. It also facilitates the application and distribution of the hair composition at the level of the root of the hair homogeneously, and thus provides an optimal cleaning. On the other hand, the composition leaves less white residues while being more styling than the known products. By associating the sebum absorbing powder with a styling powder comprising one or more water-insoluble mineral compounds, it is also possible to obtain a styling effect, especially for the supply of volume and mass to the hair and the detachment of the roots. .
[0003] The present invention also relates to a method of dry washing and treating hair, comprising the implementation of the device as defined above. In particular, the method comprises a step of spraying by means of the aerosol device according to the invention, on the keratin materials, of the composition 30 according to the invention. Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and the example which follows. In what follows, and unless otherwise indicated, the boundaries of a domain of values are included in this field, especially in the expressions "between 35" and "ranging from ... to ..." .
[0004] Moreover, the expression "at least one" used in the present description is equivalent to the expression "one or more". According to the invention, the aerosol device comprises a container which contains a cosmetic composition comprising one or more sebum-absorbing powders having a sebum uptake greater than or equal to 35 ml / 100 g. For the purposes of the present invention, the term "absorbent sebum powder" means a powder capable of absorbing and / or adsorbing sebum which has a sebum uptake of greater than or equal to 35 ml / 100 g. Sebum intake is the amount of sebum absorbed and / or adsorbed by the powder. It is expressed in ml of sebum per 100 g. of powder and measured using the method of determining the setting of powder oil described in standard NF T 30022. The intake of powder oil corresponds to the amount of sebum absorbed on the available surface of the powder by Measure the Wet point 'as shown below.
[0005] The measurement method is as follows: a quantity m (in grams) of between 0.5 and 5 grams of powder is placed on a glass plate, the quantity depending on the density of the powder, and then added dropwise artificial sebum having the following composition: - Triolein 29% by weight - Oleic acid 28.5% by weight - Oleyl oleate 18.5% by weight - Squalene 14% by weight - Cholesterol 7% by weight - Cholesterol palmitate 3% by weight After addition of 4 to 5 drops of artificial sebum, the artificial sebum is incorporated in the powder with a spatula and artificial sebum is added until the formation of sebum conglomerates. artificial and powder. From this point on, the artificial sebum is added one drop at a time, and the mixture is then triturated with the spatula. The addition of artificial sebum is stopped when a firm and smooth paste is obtained. This paste should be spread on the glass plate without cracks or lumps. We then note the volume Vs in ml of artificial sebum used. Sebum intake corresponds to the ratio Vs / m.
[0006] The sebum-absorbing powder (s) used in the aerosol device of the invention preferably has a sebum uptake ranging from 35 to 1000 ml / 100 g, more preferably from 35 to 800 ml / 100 g.

[0017] When the ester or fatty esters is or are present in the device of the invention, their amount is preferably from 0.1 to 30% by weight, more preferably from 1 to 10% by weight by weight. relative to the total weight of the composition, when the agent (s) propellant (s) are present in the composition. The composition contained in the aerosol device of the invention may also comprise propylene carbonate, preferably in an amount ranging from 0.05 to 13% by weight relative to the total weight of the composition, when the propellant (s) are present in the composition. 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, mother-of-pearl, glitter. 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 agent (s) propellant (s) are present in the composition.
[0018] Those skilled in the art will be careful to select 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.
[0019] 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 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 sufficient pressure to release the product in the form of a spray. The container is equipped at its upper end with a valve ensuring the tightness 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 dispensing means is also called a 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, defining at least partially at least one dispensing orifice.
[0020] 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. With the device of the invention, a passage is formed through the dispensing means and more particularly through the body and the cooperating part, allowing air circulation 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 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 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, 2 and 80, preferably between 5 and 60. It may for example be equal to 10. The dispensing orifices each have, for example, an upper cross section or equal to 0.0025 mm 2, better still 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 from each orifice is swirling, in particular by means of at least two swirl channels oriented tangentially around 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. The body can define a housing in which is received the cooperating part, which is then called core. The dispensing orifice (s) can be opened at rest. By "at rest" it is necessary to understand before the cooperating portion is exposed to the pressure of the product 3031438 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 moment of dispensing the product, thanks for example to the elasticity of at least a portion of the body or the cooperating part, which deforms under the pressure of the product at the moment of distribution. Thanks to the invention, in the case of spraying, the spray can be emitted with a relatively large flow rate, if desired, while having a relatively simple construction distribution means and reliable operation. 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 surface flaring outwards, respectively converging towards the outside, and the cooperating portion having a second surface facing the first surface, diverging outwards, respectively converging towards the outside . The first surface can be tapered. The second surface may be conical, of the same angle as the first or upper or lower angle. 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 25 is defined by the general direction towards 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.
[0021] They are preferably of cylindrical shape or of approximately cylindrical shape. 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 further widens the application area of the multi-orifice diffuser. 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.
[0022] With the same valve, different types of spray can be obtained by choosing the number and the section of the orifices. For example, it will be 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 10 orifices of 0.1 mm 2 to obtain a powerful spray.
[0023] The orifices may 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 we can make 15 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 function "centerpost" at the back. The cooperating portion is preferably reported, 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 the foam. 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 do not exit through the dispensing orifice. 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.
[0024] 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.
[0025] 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 least 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 15 at other 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 by 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 between 0.01 and 1 mm, more preferably 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 by a value 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.
[0026] The invention makes it easy to produce, if desired, a circular inner contour dispensing orifice. The inside diameter of the passage 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.
[0027] 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.
[0028] The dispensing orifice may be axial, in axial half-section, convergent or divergent with respect to the direction of spraying. The invention also relates to an aerosol device comprising: a container containing: one or more propellants, and a composition comprising one or more sebum-absorbing powders having a sebum uptake greater than or equal to 35 ml / 100 g, 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, a cooperating part, including a core, defining with the body, at rest, at least one annular section distribution orifice.
[0029] 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 sebum-absorbing powders having a higher sebum intake or equal to 35 ml / 100 g, the propellant (s) that may be present in the composition or, in the container, separated from the composition, a means for dispensing 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 at least one particularly annular section distribution orifice at rest or several dispensing orifices distributed around a distribution axis (Z), the dispensing means being non-traversing along the distribution axis (Z), the body being closed along the distribution axis (Z) and said part being nota member 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 detailed description which will follow, nonlimiting examples of implementation 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 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. 5 illustrates the possibility of realizing the means dispensing system with two dispensing orifices according to the invention, FIG. 6 is a front view of a distribution means with concentric dispensing 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 alternative embodiment of the orifice. 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. 12A-12C illustrate various 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. 14 is a partial axial section of an embodiment variant of FIG. 15 is a section along XV of FIG. 14, FIG. 16 is an embodiment of the body according to FIG. 14, and FIG. 17 is a perspective view. Fig. 14. In the drawing, the actual respective proportions of the different components 5 have not always been respected, for the sake of clarity. The dispensing means 1 shown in Figures 1 to 3 is intended to equip a not shown container, provided with a hollow valve or pump stem, through which the product to be dispensed contained in the container is conveyed to the dispensing means 1 .
[0030] The container may in particular be a pressurized container of the aerosol can, 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 dispensing means 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 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 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 This latter is, for example, coaxial with the stem of the container but could be oriented differently and comprise, for example, several differently oriented portions. 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.
[0031] By "annular section" is meant within the meaning of the present invention any section following a closed contour, whether this contour is circular, elliptical, polygonal or other. 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, better 15, 20 or 30 mm.
[0032] The opening 90 contributes to giving the dispensing means a particularly aesthetic appearance. 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 provided by it, if any. The opening 90 may also make it possible to introduce a finger or a lock of hair through the dispensing means, which may make it possible to apply a product in a single gesture over the entire circumference of the element introduced through the means of distribution. This may be an advantage for applying, for example, 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 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.
[0033] 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 the axis Z, of the ring 94, being preferably closer to the rear end 94a than the front end 94b, as shown in FIG. 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.
[0034] 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 supply 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 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 I, it can be made so that the product can exit 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. The core 10 can be fixed in various ways on the body 3. In the example 5 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 from the body 3 and attached to it. 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.
[0035] 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 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 20 diagrammatically illustrated 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. The end wall 22c is connected to a proximal portion 22a by an inclined intermediate portion 22b formed between facing surfaces 3b and 10b.
[0036] 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 of distribution 12.
[0037] 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 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 distribution axis Z) d at least 0.5 mm.
[0038] 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. 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. 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.
[0039] The width w of the distribution chamber 22d is greater than that of the terminal portion 22c which opens out on the dispensing orifice 12. The distribution chamber 22d improves the distribution of the product before the latter gains the larger portions. narrow 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 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 spray, for example a re-entrant angle. This intermediate portion 22b may 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 of rotation. distribution Z. The variant of Figure 4B does not include a distribution chamber.
[0040] In the variant of FIG. 4C, the end portion 22c communicates directly with that 22a in which the centering projections 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. In the variant of FIG. 4D, the cooperating part 10 is external to the body 3.
[0041] The cooperating portion 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 route the product to the delivery port 12. The supply 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 part 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 Figure 4F, there is illustrated the possibility of having no angle between the axis of distribution and the Z axis of the cooperating portion 10. The supply channel 7 opens for example on a distribution chamber 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 making it possible to deliver the product under the shape 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.
[0044] 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 a variety of ways on the dispensing means. For example, the spraying axes are parallel, or at an angle, being for example intersecting.
[0045] 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 dispense 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 can 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 have at its center a ring 43 serving as a support for the cooperating portion 10. The skirts 41 30 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 internal face 11 of the core 10. The legs of the U of the core 10 are fixed in the channels 3031438 25 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 4 3 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 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. by their orientation with respect to the dispensing orifice, they 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 internal faces 14 of the core 10.
[0046] In a variant not shown, the core 10 has, in particular in the form of indentations 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 pads 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.
[0047] The core 10 may extend, as illustrated in FIG. 13A, recessed with respect to the body by a value of between 0 and 1 mm, better still 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 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 10 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.
[0048] The dispensing means may be fed with two products which are dispensed through 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.
[0049] 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 for prohibiting 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 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 part.
