    Dispensing head of a cosmetic composition formed by mixing a first cosmetic product with a second cosmetic product, device and associated method
    The present invention relates to a dispensing head of a cosmetic composition formed by mixing a first cosmetic product with a second cosmetic product, comprising: a pipe for preparing and dispensing the cosmetic composition capable of being simultaneously connected to a first cosmetic product; reservoir of first cosmetic product, and a second reservoir of second cosmetic product, the preparation and dispensing duct opening out of the head; - A static mixer disposed in the preparation and dispensing conduit, the static mixer defining a circulation passage and mixing the first cosmetic product with the second cosmetic product.
    This head is intended to be mounted on a container containing at least two cosmetic products intended to be mixed. The container, provided with its head, forms a device for packaging and dispensing the cosmetic composition.
    A cosmetic product is in particular a product as defined in Regulation EC No. 1223/2009 of the European Parliament and of the Council dated November 30, 2009, relating to cosmetic products.
    The aforementioned dispensing head is particularly usable for forming a cosmetic composition from two different products, which react together and can not be stored in contact with each other, but which must be mixed just before use.
    This is particularly the case for hair oxidation dyes. In this type of composition, the oxidant and the dye must be stored separately and are mixed only at the time of application of the dye composition to the hair.
    The oxidation dyes are sometimes marketed in a package containing a bottle filled with oxidant, a tube filled with a coloring paste, and a lightweight tray of thermoformed plastic material, in which the oxidant and the coloring paste are mixed. This packaging also contains, most often, a brush for mixing the two products in the tray and the application of the resulting mixture, lock by strand, on the hair.
    Such a mode of conditioning requires manual intervention of the user to form the composition, which is tedious, especially for a particular. Other modes of packaging and delivery of cosmetic compositions, especially in the form of aerosols are much more convenient to use. In particular, there are dispensing heads comprising a diffuser allowing the simultaneous actuation of the two aerosol stems, either with a single aerosol and two product bags (as for example in EP2597055 and EP2657151), or with two aerosols held together (FR2875797). The product comes out through a dispensing spout.
    These heads function satisfactorily with fluid products that mix easily. However, the coloring products are particularly viscous products, the oxidant may have a viscosity of the order of 10 000 mPa.s and the dye of the order of 5000 mPa.s. As a result, their mixing does not occur naturally.
    However, to obtain a dye composition with good properties, it is essential to have a homogeneous mixture between the oxidant and the dye, with a constant volume ratio during the distribution, and especially in a ratio of one to one. A heterogeneous mixture does not guarantee satisfactory use properties, and requires manual action by the user.
    To improve the mixing, containers comprising a dispensing spout equipped with a static mixer of helical or baffled type are known. However, the distributed colorants are too viscous to form turbulent flow in such mixers. This type of mixer is therefore unsuitable.
    An object of the invention is to obtain a cosmetic product dispensing head which allows the efficient mixing of two viscous cosmetic products to deliver simply and without manual mixing of the user a cosmetic composition having very satisfactory use properties. For this purpose, the subject of the invention is a head of the aforementioned type, characterized in that the mixer comprises: at least one longitudinal wall for separating the passageway into a first region and a second region, the longitudinal wall defining at least one a through hole connecting the first region to the second region; at least one first mixing element projecting into the first region; at least one second mixing element projecting into the second region.
    The head according to the invention may comprise one or more of the following characteristics, taken separately or in any technically possible combination: the longitudinal partition wall defines a plurality of successive through holes spaced longitudinally along the longitudinal wall; ; the or each first mixing element and / or the or each second mixing element is situated at the periphery of the through-hole; the or each first mixing element projects from a first face of the longitudinal wall delimiting the first region, the or each second mixing element projecting from a second face of the longitudinal wall delimiting the second region; ; a plurality of first mixing elements staggered in the first region and / or comprising a plurality of second mixing elements, staggered in the second region; the or each first mixing element and / or the or each second mixing element comprises a transverse partition, and a longitudinal partition projecting from the transverse partition; - the longitudinal partition passes through the through hole; - the longitudinal wall extends over the entire width of the passage; the mixer defines an upstream collection chamber of the first cosmetic product and the second cosmetic product, disposed upstream to the circulation passage, and a dispensing nozzle of the cosmetic composition, without mixing elements, disposed downstream of the passage of circulation; the mixer is removably mounted in the preparation and dispensing duct. The subject of the invention is also a device for packaging and / or dispensing a cosmetic composition, comprising: a first reservoir containing a first cosmetic product; a second reservoir containing a second cosmetic product; - A head as defined above, the preparation and distribution duct being adapted to be simultaneously connected to the first tank and the second tank.
    The device according to the invention may comprise one or more of the following characteristics, taken alone or in any technically possible combination: the viscosity of the first cosmetic product is greater than 1000 mPa.s, in particular greater than 5000 mPa. s; the viscosity of the second cosmetic product is greater than 1000 mPa.s, in particular greater than 10,000 mPa.s. The subject of the invention is also a process for dispensing a cosmetic composition comprising the following steps: providing a device as defined above; - Simultaneous distribution of first cosmetic product and second cosmetic product in the preparation and distribution line from the first reservoir and the second reservoir respectively; - Formation of the cosmetic composition in the mixer by passing at least a portion of the mixture of the first cosmetic product with the second cosmetic product successively in contact with a first mixing element, through a through hole, and / or in contact with a second mixing element.
    The method according to which the invention may comprise the following characteristic: the Reynolds number of the first cosmetic product at its entry into the preparation and distribution conduit is less than 1 and the Reynolds number of the second cosmetic product at its entry into the mixing duct is less than 1. The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the accompanying drawings, in which: FIG. a first device for packaging and dispensing a cosmetic composition, the device comprising a mixer according to the invention; - Figure 2 is a side view of the head of Figure 1; FIG. 3 is a bottom perspective view of three-quarter faces of the mixer of the device of FIG. 1; FIG. 4 is a view from below of the mixer of the device of FIG. 1; FIG. 5 is a front view of the mixer of the device of FIG. 1; - Figure 6 is a view taken in section along a longitudinal plane VI-VI of Figure 5.
    A first device 10 for packaging and dispensing a cosmetic composition obtained by mixing a first cosmetic product and a second cosmetic product is illustrated in FIGS. 1 to 5.
    The cosmetic composition is for example a coloring composition of the keratin fibers of a user, in particular the hair of a user.
    The cosmetic composition is made from a first cosmetic dye product and a second oxidizing cosmetic product. The first cosmetic product and the second cosmetic product are stored separately in the device 10.
    The first cosmetic product comprises in a known manner an alkaline agent. The alkaline agent is, for example, inorganic, such as organic ammonia, such as an organic or hybrid amine such as an amine salt. It advantageously comprises at least one coloring agent such as an oxidation dye precursor, a direct dye or their mixtures. It optionally contains at least one anionic, nonionic, cationic, amphoteric and / or zwitteronic surfactant.
    The second cosmetic product contains at least one oxidizing agent, different from oxygen in the air, such as hydrogen peroxide. It includes at least one fatty substance. By "fatty substance" is meant an organic compound which is insoluble in water at ordinary temperature (25 ° C.) and at atmospheric pressure (760 mmHg) (solubility of less than 5% and preferably of 1%, even more preferentially at 0.1%). The fatty substances are chosen, for example, from hydrocarbons, oils, fatty alcohols, fatty acid esters and / or fatty alcohol esters other than triglycerides and vegetable waxes, non-silicone waxes, silicones, and mixtures thereof. .
    It optionally contains at least one anionic, nonionic, cationic, amphoteric and / or zwitteronic surfactant.
    The first cosmetic product and the second cosmetic product are here viscous products. The first cosmetic product and the second cosmetic product may each have a viscosity ranging from 1000 mPa.s to 60000 mPa.s, preferably from 5000 mPa.s to 40000 mPa.s.
    For example, the viscosity of the first cosmetic product is in particular between 10000 mPa.s and 40000 mPa.s.
    The viscosity of the second cosmetic product is in particular between 5000 mPa.s at 15000 mPa.s.
    The viscosity of the products is measured at 25 ° C with a Brookfield LVT viscometer equipped with a mobile M4 rotating at a speed of 12 revolutions per minute. The measurement is taken after 1 minute.
    To form the cosmetic composition, the first cosmetic product and the second cosmetic product are mixed within the device 10 which distributes the cosmetic composition thus formed.
    In this example, the first cosmetic product and the second cosmetic product are respectively received in a first reservoir 12 and in a second reservoir 14 of the device 10, in the form of an aerosol, comprising a propellant gas.
    In one embodiment, the propellant gas is common to the first cosmetic product and the second cosmetic product. It is arranged in the space located outside the first reservoir 12 and the second reservoir 14. In a variant, the propellant gas is disposed in each reservoir 12, 14.
    As illustrated by FIG. 1 and FIG. 2, the packaging and dispensing device 10 comprises a receptacle 16 receiving the reservoirs 12, 14, and a mixing head 20 for cosmetics and dispensing the cosmetic composition, mounted on a neck 18 of the container 16.
    Each reservoir 12, 14 is provided at its upper end with a product dispensing member 22. The dispensing member 22 is here a movable rod controlling the opening of a valve.
    The displacement of the product dispensing member 22 allows the dispensing of each product from the reservoir 12, 14 to the outside.
    With reference to FIG. 1, the mixing and dispensing head 16 comprises a collar 24 mounted on the neck 18, a diffuser 26 mounted on the collar 24, and a mixer 28 of products inserted in the diffuser 26.
    The diffuser 26 comprises a cover 30 assembled on the band 24, a conduit 32 for preparing and dispensing the cosmetic composition, receiving the mixer 28, and at least one movable member 34 for actuating the mixture and the distribution.
    The preparation duct 32 comprises a first upstream section 36, mounted on the dispensing member 22 of the first reservoir 12, a second upstream section 38, mounted on the dispensing member 22 of the second reservoir 14, and a dispensing spout 40. connected to the upstream sections 36, 38. The dispensing spout 40 projects partially out of the cover 30 to receive the mixer 28. The movable actuating member 34 is able to move the first upstream section 36 and the second upstream section 38 to simultaneously actuate the dispensing member 22 of the first reservoir 12 and the dispensing member 22 of the second reservoir 14.
    Referring to Figures 3 to 6, the mixer 28 is formed of a removable cartridge inserted into the dispensing spout 40. It extends along a central axis A-A '.
    The mixer 28 comprises an upstream portion 50 for receiving the first upstream section 36 and the second upstream section 38 for collecting the first cosmetic product and the second cosmetic product. It comprises a central pipe 52 for mixing the first cosmetic product with the second cosmetic product to form the cosmetic composition, and a nozzle 54 for dispensing the cosmetic composition out of the device 10.
    In this example, the mixer 28 further comprises a member 56 for fixing the spout 40 of the diffuser 26.
    The upstream portion 50 is hollow. It defines an upstream chamber 58 for collecting the first cosmetic product and the second cosmetic product. The upstream section 36 and the second upstream section 38 open on either side of the upstream chamber 58, on each side of the axis A-A '. The upstream chamber 58 has a central convergence region 60, situated on the axis A-A ', at the inlet of the central pipe 52.
    Membranes 61 laterally delimit the central region 60.
    The central pipe 52 extends here along the axis A-A 'between the upstream chamber 58 and the nozzle 54. It comprises a tubular peripheral wall 62 defining a central passage 64 of axis A-A'.
    According to the invention, the central pipe 52 further comprises a longitudinal wall 66 for separating the central passage 64, a plurality of first mixing elements 68 arranged in a first region of the central passage 64, on one side of the separation wall. longitudinal 66 and a plurality of second mixing elements 70 disposed in a second region of the central passage 64 on the other side of the longitudinal dividing wall 66.
    In this example, the central passage 64 has an elongated cross section along an axis B-B 'perpendicular to the axis A-A', visible in Figure 5. This section is here substantially oval.
    The longitudinal wall 66 separates the central passage 64 in the first region and in the second region along the axis B-B '. The first and second regions are disjoint. They are delimited respectively by a first face 72 of the longitudinal wall 66 and by a second face 74 of the longitudinal wall 66.
    The longitudinal wall 66 extends over the entire width of the central passage 64 between two opposite sides of the peripheral wall 62.
    The longitudinal wall 66 is perforated. It has a plurality of through holes 76, extending perpendicular to the axis A-A 'being spaced longitudinally from each other.
    The through holes 76 open on the first face 72 and the second face 74 to connect the first region to the second region. In this example, they also extend over the entire width of the central passage 64. The through holes 76 adjacent are separated longitudinally from each other by a solid portion of the longitudinal wall 66.
    The first mixing elements 68 are spaced longitudinally from each other along the axis A-A '. They are arranged in staggered rows. They project towards the axis A-A 'respectively from a first side and from a second side of the peripheral wall 62 towards the axis A-A'. They also protrude away from the longitudinal wall 66 from the first face 72.
    In this example, the first mixing elements 68 are each located facing a through hole 76.
    Each first mixing element 68 has an L-shaped horizontal section.
    Each first mixing element 68 thus comprises a transverse partition 78 extending perpendicularly to the axis A-A 'towards this axis, and at the free end of the transverse partition 78, a longitudinal partition 80 extending parallel to the axis A-A 'in the direction from upstream to downstream.
    The transverse partition 78 partially borders the through hole 76. It extends over the entire height of the first region of the central passage 64.
    The longitudinal partition 80 passes through the through hole 76 over its entire length.
    In this example, the number of first mixing elements 68 is greater than 2 and is in particular between 3 and 10.
    The second mixing elements 70 are arranged in the second region symmetrically along the axis A-A 'relative to the first mixing elements 68. They have a structure identical to that of the first mixing elements 68, which will not be recovery in detail.
    The longitudinal partition 80 of each second mixing element 70 joins the longitudinal partition 80 of a first mixing element 68 through the through hole 76.
    The longitudinal wall 66, the first mixing elements 68 and the second mixing elements 70 thus define in the central pipe 52 tortuous paths through the mixture formed by the first cosmetic product and the second cosmetic product. These paths pass successively above and below the longitudinal wall 66 through the through holes 76. They also pass zig-zag on either side of the longitudinal wall 66, being delimited laterally and transversely respectively against the first mixing elements 68 and against the second mixing elements 70.
    The nozzle 54 extends to the downstream end of the central pipe 52. It projects longitudinally along the axis A-A '.
    In this example, the fixing member 56 is formed by a detent pin 82 intended to be received in a corresponding opening formed in the diffuser 26, at the bottom of the spout 40.
    Advantageously, the mixer 28 is removably mounted in the duct 32. In the example shown in Figures 3 to 6, the upstream chamber 58 and the central passage 64 are open downwards. The spout 40 closes down the upstream chamber 58 and the central passage 64 when the mixer 28 is received in the spout 40.
    The dispensing nozzle 54 projects out of the spout 40, as can be seen in FIG. 2.
    Such an arrangement allows simple cleaning of the mixer 28 when this is necessary. In addition, the molding of the mixer 28 in one piece is possible.
    The mounting of the device 10 will now be briefly described.
    Initially, the first reservoir 12 and the second reservoir 14 are respectively filled with the first cosmetic product and the second cosmetic product in the container 16. The diffuser 26 is placed on the mounting collar 24 which is then assembled on the neck 18.
    During assembly, the first upstream section 36 and the second upstream section 38 are respectively connected to the distribution members 22 of the first reservoir 12 and the second reservoir 14.
    The mixer 28 is supplied separately and is inserted into the dispensing spout 40. The use of the device 10 will now be described.
    Initially, the user grasps the receptacle 16 and presses the movable member 34. The displacement of the movable member 34 causes the simultaneous movement of the first upstream section 36 and the second upstream section 38 and the activation of the distribution members 22 This produces the simultaneous distribution of the first cosmetic product from the first reservoir 12 and the second cosmetic product from the second reservoir 14.
    The first cosmetic product and the second cosmetic product respectively go upstream through the first upstream section 36 and through the second upstream section 38 to reach the upstream collection chamber 58. The first cosmetic product and the second cosmetic product meet in the central region. converging 60 and enter the central pipe 52 at an angle of 90 °.
    In the central duct 52, the first product flow and the second product flow are each separated horizontally by the longitudinal wall 66 and combine on either side of this wall 66.
    In contact with the first mixing elements 68 and the second mixing elements 70, the flows are offset laterally with respect to the axis A-A 'and follow a tortuous zig-zag path until they reach a through hole 76.
    During the passage opposite each hole 76, a portion of the flow flowing over the longitudinal wall 66 passes through the hole 76 to mix with another part of the flow flowing beneath the longitudinal wall 66.
    Likewise, a part of the flow flowing beneath the longitudinal wall 66 passes through the hole 76 to mix with another part of the flow flowing over the longitudinal wall 66.
    The flows of cosmetic products therefore follow both a sinuous horizontal zig-zag-shaped course on either side of the longitudinal wall 66 while progressing along the axis A-A ', but also a perpendicular vertical path to the longitudinal wall 66 through the successive through holes 76.
    The mixture of the first cosmetic product with the second cosmetic product is therefore particularly effective, given the turbulence generated, despite the high viscosities of the first cosmetic product and the second cosmetic product.
    This produces a very homogeneous cosmetic composition, with a weight ratio of between 0.25 and 4, preferably between 0.5 and 2, especially one to one, which thus has optimum use properties. This is achieved without manual intervention of the user to mix the products, with a simple mixer 28 having the structure defined above. For example, when the rods of the distribution members 22 have a cross section of about 2 mm, the respective exit speed of the first cosmetic product and the second cosmetic product out of the tanks is of the order of 2 m / s. The Reynolds number of the first cosmetic product is then about 0.2 for a viscosity of 10,000 mPa.s and the Reynolds number of the second cosmetic product is about 0.4 for a viscosity of 5000 mPa.s.
    The overall rate of return is of the order of 0.2 m / s at the outlet of the dispensing spout 40. In the absence of mixer 18, the flow in the spout 40 is purely laminar and no mixing occurs. between the first cosmetic product and the second cosmetic product.
    The presence of the mixer 18 ensures a very efficient mixing, thanks to the tortuous three-dimensional displacement within the mixer 18, making it possible to form the composition after passing through the central pipe 52.
    Such an effect is not obtained using simple baffles in two dimensions, or with a helix devoid of tortuosity.
