Abstract

The device (1) has a container (2) provided with a variable interior volume (8) and presenting a distribution opening (4). Two distinct cosmetic compositions for application on skin are located in different areas (10, 20) in the container and in contact with each other. Each composition includes viscosity to maintain its distribution in the container in a stable manner during storage. The compositions leave through the opening simultaneously without mixing closely when the volume is decreased. The compositions comprise a coloring agent in form of inorganic pigment. The inorganic pigment is selected among metallic oxides such as iron oxides. The compositions are aqueous or oily. The compositions are make-up compositions and/or care compositions.

Description

The present invention relates to cosmetic, makeup and / or care products. The invention also relates to devices for packaging and dispensing such products.

"Cosmetic composition" means a composition as defined in Council Directive 93/35 / EEC of 14 June 1993 amending Directive 76/768 / EEC. For the care and make-up of the skin, many women simultaneously use several skincare and / or make-up care skin care products, among which skincare creams, active care concentrates, foundation creams may be mentioned in particular. and various make-up products. They would therefore find it advantageous to use products that apply in a single gesture and that combine the benefits of several of their cosmetic products, such as the combination of a care cream with a pigment composition. Such combinations would be easier to apply and to dose compared to several successive applications of different products. Before the application of a care cream, a large number of women apply a concentrate of active ingredients such as serum, in order to reinforce the care effects. They often ask to be able to have a cream of care reinforced in assets.

Unfortunately for technical reasons, mainly related to the solubilities of the active agents and / or particulate dyes and therefore to the maximum concentrations that can be incorporated, it is not easily achievable. The application of a care cream is an important cosmetic gesture for women who are attached to the care and texture benefits of their skincare cream. They often ask to be able to have in foundation of textures identical to these last ones. Unfortunately, for technical reasons mainly related to the pigmentation of these creams, it is not easily achievable. The problems encountered are for example. due to the grinding of the pigments and their risk of sedimentation within the emulsion.

When makeup, many women use a foundation and complexion-specific makeup products, such as a whitening base, an illuminator base to give shine, a finish illuminator, a good-looking product, bronzing or to correct redness. Women often ask for a makeup result using only one product. Unfortunately for technical reasons mainly related to the maximum incorporable concentrations of specific ingredients allowing these specific makeup effects, it is not easily achievable. Indeed, in order to preserve the stability of the formulas, to preserve their texture and their qualities of application, to avoid the incompatibilities between ingredients, it is often necessary to limit the concentrations of certain ingredients.

Obtaining a unique composition combining certain properties or performances is not always technically feasible. Indeed, the ingredients underlying the properties and performance sought, are not always compatible with each other, or are not always conveyable in a common composition. In addition, incorporation into a common composition, when technically feasible, is detrimental to the visualization of these ingredients or their effects. This visualization is known to be very important in the perception of the product and its performance by the woman. There are solid cosmetics with a mixture of two compositions. These products are generally difficult to apply.

The present invention relates to fluid compositions. Patents DE 1,112,447 and FR 2,113,128 describe devices for the simultaneous dispensing of two compositions of similar consistency contained in a container. The toothpaste tubes arranged so that the toothpaste is distributed in the form of a multicolored bead, for example striped, are known. US Patent 5,590,818 discloses a partitioned tip which can in particular be used to fill toothpaste tubes with pastes of different colors so that the toothpaste is streaked from the tube. The international application WO 99/01342 relates to an apparatus for filling a toothpaste tube with two different pastes that come out of the tube in the form of two concentric layers of toothpaste.

The international application WO 03/097486 relates to a toothpaste tube comprising a pump and a piston. The application W007004199 relates to a container containing a multi-phase capillary composition, the phases being separated in the container and a single phase being in contact with the inner wall of the container. Applications WO2007 / 004200, WO2007 / 007279 and WO2006 / 102113 relate to compositions comprising several phases in contact in the same container and having particular rheologies. European application EP 0 907 345 discloses a skin care product comprising an aqueous phase and an oily phase which flow in the form of parallel filaments through an orifice provided with a tip. Having an aqueous phase and an oily phase avoids the risk of migration of a dye in solution in one of the phases to the other phase during storage. However, the presence of aqueous and oily phases imposes formulation constraints and can prevent certain textures from being obtained. The application WO2009 / 053898 discloses a cosmetic composition comprising a translucent phase and two opaque phases, coming out in a homogeneous form from a container where they are packaged without mixing. This application teaches to distribute a combination of compositions already mixed at the outlet of the conditioning device, and delivers a gel, which is limiting in terms of formulation. In addition, the contact surface between the compositions is relatively large, which increases the risk of diffusion of certain ingredients from one composition to another.

There is therefore a need to further improve the existing devices. It is particularly interesting to develop a device for delivering a combination of products whose characteristics and benefits are preserved while allowing the visual identification of each benefit, for example like the combination of a care cream. to a concentrate of active ingredients or a pigmented formula, or a foundation to a makeup product with specific effects and then apply in a single gesture the combination.

The invention aims to obtain, packaged in a single container, the advantages associated with the combination of two or more cosmetic compositions having at least two distinct properties and which are, if possible, viewable by the user. According to a first aspect, the subject of the present invention is a packaging and dispensing device comprising: a container of variable internal volume having a dispensing orifice; at least first and second distinct cosmetic compositions to be applied to the skin, different of a toothpaste, disposed within the container, where the compositions are of different visual aspects, where the compositions are located in at least first and second respective distinct regions of the container, in contact with each other and each composition having a viscosity sufficient to stably maintain its distribution in the container during storage, the compositions exiting simultaneously through the orifice without intimately mixing when the interior volume of the container is decreased. The invention makes it possible to visualize the various compositions at the outlet of the container.

The first and / or second composition comprises, according to the invention, at least one coloring agent in the form of inorganic pigment, for example selected from metal oxides, preferably iron oxides. The presence of inorganic pigment can reduce the risk of color diffusion between the first and second compositions regardless of the foimulation of these compositions. This may allow for example to have first and second compositions both aqueous or oily while preserving the visual differentiation properties during their distribution. As a result, less formulation constraint and greater textural diversity can be achieved. Combination of cosmetic compositions. The compositions contained in the container according to the invention may be fluid and may be, for example, in pasty form, or in the form of a gel or a cream. By the expression "different visual aspects" are meant compositions visually distinct. The compositions can be of various different colors, or include particles, flicker or have a pearlescent or pearlescent appearance. For the purposes of the present invention, white is not a color and "coloring agent" is understood to mean a substance capable of giving color. The term "dyestuff" means a substance capable of modifying the visual appearance by adding color and / or optical effect. The first and second compositions occupy separate and distinct physical spaces within the container in which they are packaged, but are in direct contact with each other, in particular they are not separated by a wall and are not emulsified one without the other. The first and second regions of the container are defined by the volume occupied by each corresponding composition. The first and / or second region may define a single volume or be separated into several distinct volumes; for example the first region may form several scratches or strips of non-zero thickness at the periphery of the second region.

Each composition inside the container is in contact with at least one other composition. The compositions, while exiting simultaneously through the orifice without mixing, can form a regular pattern, in particular chosen from one or more stripes or bands, concentric layers or a combination of several of these patterns.

The compositions do not mix without specific mechanical action of the user to mix them. The compositions do not come out mixed from the container, which allows the user to always visualize their differences in appearance and to better understand the expected benefits attached to each composition; it is only by deliberately mixing the various compositions, that one can form a single and homogeneous product on the skin. The mixture of the compositions can be done just before or at the time of application.

The mixing can be done manually, for example by mixing the user with a quantity of product distributed in the palm of his hand just before application to the skin. The mixture can be performed with the finger or with a possibly heated and / or vibrating applicator.

The content of the first composition may be between 3% and 50% of the total volume of the compositions, or even between 10% and 50% of the total volume of the compositions, depending on the nature of the compositions and their cosmetic properties. The first and / or second composition may be a makeup composition, for example a foundation, to be applied to the face, neck and / or the rest of the body, or a self-tanning cream. The first and / or second composition may be a care composition, for example a care cream, a serum or a sunscreen. The first and second composition may be for application throughout the body or specific areas, such as the face and neck. The cosmetic compositions may be in substantially equal quantity in the container, in particular a care cream and a make-up composition, for example a colored foundation-type composition. The following table shows some possibilities Second omposition First Care Cream Foundation Self-tanning cream Sunscreen composition Cream care --- ee ".. 1111111MIIIIII" ...- yes yes yes Foundation yes yes yes Example: 50 % by volume make-up and 50% by volume cream of care Cream self-yes yes yes bronzer Sunscreen yes yes yes According to an alternative, it is also possible to combine two compositions of the same type (ex: two foundations), but distinct by their color in mass (color difference perceptible to the naked eye between the two compositions, for example a color difference AE of at least 2, or even at least 3. The delta E, dE or AE , is defined as a measure of difference between two colors, here is the formula established in 1976: fr) (b1 - b) 2 = (LI - L2 .j} 2 - or: L1, a1, b1 are the coordinates in the color space of the first color to be compared and L242, b2 those of the second color in the CI system E Lab (Luminance L indices, a red, b yellow. The device may comprise a concentrate of ingredients with specific makeup effects, for example a concentrate with a luminosity effect or a concentrate with a color effect, in particular with a volume content of between 3% and 25% of the total volume of the compositions. even between 10 and 25% of the total volume of the compositions. Some compositions are intended to be used in a mixture and require to be added in very small quantities to another composition. It can thus be particularly advantageous to have a combination with a small percentage by volume of the first composition, for example less than 9%, or even between 3% and 6%, relative to the total volume of the compositions. For example, a concentrate of pigments to be mixed with a day cream, suntan or a foundation makes it possible to develop an immediate color, even in a very small proportion relative to the totality of the combination. The device may comprise a concentrate of active care effects, for example anti-aging effect, especially in a volume content of between 8% and 15% of the total volume of the compositions, or between 10 and 15% of the total volume of the compositions. The first and second compositions may not include any coloring agent that is in a form other than an inorganic pigment or a mixture of inorganic pigments. Thus, the compositions may be devoid of fat-soluble or water-soluble dye or organic pigment. In exemplary embodiments, only one of the first and second compositions is colored. The second or the first composition may, for example, be devoid of coloring agent and be a "neutral base", which may be white or transparent.

In other embodiments, the first and / or second composition further comprises at least one additional pigment chosen from: organic or inorganic pigments other than the inorganic pigment mentioned above, or inorganic and organic composites, pigments interferential or not, surface-treated or untreated, metallic pigments and multilayer pigments and their mixtures - interferential pigments, especially diffractive pigments and pigments with multilayer interference structure, such as nacres for example - diffusing pigments, generating a color by a phenomenon of absorption of color. The additional pigment can create a specific optical effect perceptible to the naked eye, for example a point shine effect, a goniochromatic effect, a spotted effect, or any other desired optical effect. The additional pigment can create, for example, highlight points within the composition, contrasting with the surrounding color. These highlight points may be due to reflective particles, for example. The pigments may be white or colored, mineral and / or organic. Among the inorganic pigments, titanium dioxide, optionally surface-treated, zirconium oxide or cerium oxides, and oxides of zinc, iron (black, yellow or red) or chromium, the violet of manganese, ultramarine blue, chromium hydrate and ferric blue, metal powders such as aluminum powder or copper powder.

At least one binder can advantageously contribute to the fixing of the organic dyestuff on the inorganic nucleus. The composite pigment particles may have various shapes. These particles may in particular be platelet-shaped or globular, in particular spherical, and may be hollow or solid. The term "platelet-shaped" denotes particles whose ratio of the largest dimension to the thickness is greater than or equal to 5. For example, a composite pigment may have a specific surface area of between 1 and 1000 m 2 / g. in particular between 10 and 600 m2 / g, and in particular between 20 and 400 m2 / g. The specific surface area is the value measured by the BET method. The inorganic core of the composite pigment may be of any form suitable for fixing particles of organic dyestuff, for example spherical, globular, granular, polyhedral, acicular, fusiform, flattened in the form of flakes, grains of rice, tortoiseshell as well as a combination of these forms, this list not being limiting. The ratio of the largest dimension of the core to its smallest dimension can be between 1 and 50.

The inorganic core may have a size of between about 1 nm and about 100 nm, or even between about 5 nm and about 75 nm, for example between about 10 nm and about 50 nm.

Goniochromatic multilayer pigment The first and / or second composition according to the invention may comprise at least one goniochromatic coloring agent chosen from interferential multilayer structures. Examples of symmetrical interferential multilayer structures are for example the following structures: Fe 2 O 3 / SiO 2 / Fe 2 O 3 / SiO 2 / Fe 2 O 3, a pigment having this structure being marketed under the name SICOPEARL by the company BASF; Fe 2 O 3 / SiO 2 / titanium or iron oxide / mica / titanium oxide or iron oxide / SiO 2 / Fe 2 O 3; TiO 2 / SiO 2 / TiO 2 and TiO 2 / Al 2 O 3 / TiO 2, pigments having these structures being sold under the name XIRONA by the company Merck (Darmstadt). It is also possible to use certain nacres, pigments having effects on a synthetic substrate, in particular substrate such as alumina, silica, borosilicate, iron oxide or aluminum oxide. Diffractive Pigments For the purpose of the present invention, the term "diffractive pigment" denotes a pigment capable of producing a color variation according to the angle of observation when illuminated by white light, because of the presence of a pigment. structure that diffracts light. A diffractive pigment may comprise a diffraction grating, capable for example of diffracting in defined directions an incident monochromatic light ray. The diffraction grating may comprise a periodic pattern, in particular a line, the distance between two adjacent patterns being of the same order of magnitude as the wavelength of the incident light. When the incident light is polychromatic, the diffraction grating will separate the different spectral components of the light and produce a rainbow effect. The diffractive pigment may be made with patterns having different profiles, in particular triangular, symmetrical or not, in crenellations, of constant width or not, sinusoidal.

The spatial frequency of the network and the depth of the patterns will be chosen according to the degree of separation of the different orders desired. The frequency can vary for example between 500 and 3000 lines per mm. The diffractive pigment used may in particular be chosen from those described in US patent application US 2003/0031870 published on February 13, 2003. A diffractive pigment may comprise, for example, the following structure: MgF 2 / Al / MgF 2, a diffractive pigment having this structure being marketed under the name SPECTRAFLAIR 1400 Pigment Silver by the company FLEX PRODUCTS, or SPECTRAFLAIR 1400 Pigment Silver FG. The proportion by weight of the MgF 2 can be between 80 and 95% of the total weight of the pigment. Reflective Particles For the purposes of the present invention, the term "reflective particles" denotes particles whose size, structure, in particular the thickness of the layer or layers constituting it and their physical and chemical natures, and surface condition. , allow them to reflect the incident light. This reflection may, if necessary, have sufficient intensity to create on the surface of the composition, when it is applied to the support to make up, highlight points visible to the naked eye, that is to say say brighter points that contrast with their surroundings by appearing to shine.

The reflective particles may be selected so as not to significantly alter the coloring effect generated by the coloring agents associated with them and more particularly so as to optimize this effect in terms of color rendering. They may more particularly have a color or a yellow, pink, red, bronze, orange, brown, gold and / or coppery reflection.

The presence of these particles may make it possible to extend the color range of the first and / or second composition. It can also be used to add colored highlight points. The reflective particles may have various shapes, in particular be in the form of platelets or globular, in particular spherical.

The reflective particles, whatever their failure, may have a multilayer structure or not and, in the case of a multilayer structure, for example at least one layer of uniform thickness, including a reflective material.

When the reflective particles do not have a multilayer structure, they may be composed for example of metal oxides, including synthetically obtained titanium or iron oxides. When the reflective particles have a multilayer structure, these may for example comprise a natural or synthetic substrate, in particular a synthetic substrate at least partially coated with at least one layer of a reflective material, in particular at least one metal or metal material. . The substrate may be monomaterial, multimaterial, organic and / or inorganic. More particularly, it may be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, synthetic mica and mixtures thereof, this list not being limiting. The reflective material may include a layer of metal or a metallic material.

The device can thus comprise all the multi-combinations of the cosmetic products mentioned above, in particular the combinations of two or three compositions.

Viscosity of the compositions The compositions have rheologies such that they do not mix without mechanical action inside the container, but can mix easily and homogeneously, thanks to compatible textures, at the outlet of the container just before application and must, once mixed, have good cosmetic properties. Viscosity should avoid as much as possible the flow and unintentional mixing of the compositions. First viscosity measurement technique Very low shear viscosity characterizes the texture of the composition at rest or near-rest: Measurements are carried out at 25 ° C using an imposed stress rheometer, ARG2 TA Instrument, equipped with a cone-plane measuring body equipped with a bell-shaped anti-evaporation device.

For each measurement, the sample is gently placed and the measurements begin 5 minutes after the sample has been placed in the air gap. The composition is then subjected to a ramp stress of 10-3 to 102 Pa at a frequency set at 1 Hz. The first and / or second cosmetic composition preferably have, at 20 ° C, a low shear viscosity, either at 0.010 s-1 greater than or equal to 200 Pa.s and preferably between 200 Pa.s and 5000 Pa.s, in particular between 200 Pa.s and 2000 Pa.s, or even between 200 Pa.s and 1000 Pa.s.

Second measurement technique: Rheomat viscosity 25 ° C. The Rheomat viscosity is measured at 25 ° C., using a RHEOMAT RM 180 viscometer equipped with a No. 4 (M4) or No. 3 (M3) mobile. ), the measurement being performed after 10 minutes of rotation of the mobile within the composition (time at which a stabilization of the viscosity and the speed of rotation of the mobile) is observed, at a shear of 200 s-1. We obtain a measurement in UD (Unit of Diversion). The viscosity of the compositions of the invention is preferably greater than 15 UDM3, in particular greater than 20 UDM3. Here are examples of viscosities of compositions that can be used in a device according to the invention.

The device may comprise, for example: a foundation with a viscosity ranging from 30 UD M4 to 75 UD M4 or from 25 to 35 UD M4, a moisturizing cream with a viscosity ranging from 50 to 68 UD M3, a serum with a viscosity ranging from 50 at 80 UD M3, a viscosity gel ranging from 35 to 60 UD M3 or a self-tanning cream with a viscosity ranging from 15 to 25 UD M3, this list not being limiting. Container The compositions are contained in a suitable container.

Preferably, the device comprises a conventional container of a type known to those skilled in the art, in particular of toothpaste tube type. A particular embodiment thus comprises at least one complexion composition, or even only complexion compositions, in a tube tube type of toothpaste. The container may be in the form of a flexible tube, for example of plastic or metal, especially aluminum. In a variant, the container consists of a semi-rigid or rigid tube equipped with a pump and a follower piston. The first and second cosmetic compositions may be arranged inside the container in overlapping regions and occupying distinct positions along the longitudinal axis of the container, the latter having an internal chimney communicating with the dispensing orifice, a first region containing the first composition is formed in an annular space around the inner chimney and the latter opens into the second region. At least one side passage is formed through the inner chimney to allow the first composition to reach the dispensing orifice, when the second composition is pressurized to be dispensed, for example by pressing the flexible tube. The lateral passage may be a simple orifice communicating the interior of the chimney and the annular space containing the first composition. In a variant the passage communicates with the dispensing orifice via a channel which is located for example in the center of the chimney and the first composition during the outlet then forms a central core with respect to the second composition.

Any embodiment of the tube, with or without an internal chimney, such as exists in a manner known to those skilled in the art may be suitable for the invention. The cosmetic compositions may in particular be arranged inside the container in regions extending along the longitudinal axis of the container. This embodiment is particularly advantageous because it produces practically no loss of product compared to an embodiment with an annular space around an internal chimney for which part of the compositions remains trapped at the end of use in and can hardly be used. In another of its aspects, the present invention relates to a nozzle for filling a container with at least first and second different fluid compositions, comprising: a plurality of parallel filling channels, arranged so that the first and second Compositions form in the container once filled with the first and second respective distinct regions in contact with each other, the first region representing for example between 3% and 50% of the interior volume of the container. The subject of the invention is also a process for cosmetic treatment, in particular for make-up treatment, in which a certain amount of the products of the invention are withdrawn through the dispensing orifice of a container from a packaging and dispensing device according to the invention. first and second compositions, and the compositions contained in the dispensed amount are then mixed to obtain a mixture of homogeneous appearance.

The invention will be better understood on reading the following detailed description of examples of non-limiting implementation thereof, and on examining the appended drawing, in which: FIGS. 1A to 1K FIGS. 2A to 2K illustrate in section different possibilities of arrangement of the compositions at the output of the devices of FIGS. 1A to 1K, FIG. longitudinal section of the device of FIG. 1A, FIG. 4 represents, in section, a filling nozzle of a device according to the invention; FIGS. 5A to 5K show, in front view, examples of filling nozzles according to FIG. invention, and - Figure 6 shows in section another example of device according to the invention, and - Figure 7 shows a partial longitudinal section and schematic, an alternative embodiment. In the examples illustrated below, the device 1 according to the invention comprises a container 2 in the form of a flexible tube, for example of generally cylindrical shape when full, having at one end a neck 3 provided with a thread for fastening a closure cap and having a dispensing orifice 4 through which, in the form of a single and regular coil 81, a combination of at least two compositions P1, P2 or even at least three compositions P1, P2 and P3 . At the outlet of the tube, the compositions occupy separate portions 11, 21 and 31 respectively of the flange 81, these portions being in particular in the modes illustrated in the form of a central core, concentric layers or several stripes. At the outlet of the tube 2 of the device illustrated in FIG. 1A, the composition P1 forms several, for example four, longitudinal stripes at the periphery of the composition P2. In the example illustrated, the composition P1, for example a cream concentrated in pigments, representing by volume approximately 10% of the total volume of composition, is to be mixed with the composition P2, which may be a day cream, a sunscreen, a makeup cream, a moisturizer or a foundation.

The two compositions P1 and P2 remain separated until the user takes the desired quantity, applies it to a part of the body, possibly after mixing, for example in the palm of the hand. FIG. 2A represents, in front view, the preceding device, the compositions leaving through the orifice 4.

In the example shown in FIGS. 1B and 2B, the composition P2 occupies a region forming a concentric outer layer with a central core corresponding to the composition P1. Compositions P1 and P2 are, for example, as illustrated, present in substantially equal amounts. In the example illustrated in FIGS. 1C and 2C, the compositions are also arranged in concentric layers but the composition P1 corresponding to the outer layer represents only about one third of the total volume of composition. The composition P1 is, for example, a pigmented makeup product and the composition P2 is a moisturizer. In the embodiment illustrated in FIGS. 1D and 2D, the composition P1, for example an anti-aging cream, forms sidebands around a central bead formed by the composition P2, for example a foundation. The combination contains about 17% of composition P1. The mixture of compositions shown in FIGS. 1E and 2E contains two compositions in substantially equal amounts, arranged in several quarters, in this case four in number. Figures 1F and 2F show two views of the same embodiment having three compositions in substantially equal amounts. This is for example a day cream, a foundation and a moisturizer. The embodiment illustrated in FIGS. 1G and 2G also comprises three compositions in substantially equal amounts, but arranged differently as they exit the container. In the example illustrated in FIGS. 1H and 2H, the compositions P2 and P3, for example a day cream and a foundation, are contained in the container in substantially equal amounts, whereas the composition PI, for example a concentrate anti-aging, represents in volume only 10% of the total volume. The composition P1 forms several stripes, for example four in number, at the periphery of the central bead, formed mainly by two halves occupied by each of the compositions P2 and P3.

In the example illustrated in Figures II and 21, the flange of the compositions 81 at the outlet of the orifice 4 consists mainly of a core 21 of composition P2, for example day cream, each Pi composition, for example a concentrated composition in pigments, and P3, for example anti-aging agent, forming several scratches at the periphery, of which there are three in the example under consideration. In the example illustrated, the stripes 11 formed by the composition P 1 are wider than the stripes 31 formed by the composition P 3. The combination of the compositions comprises approximately by volume 6% of P1 and 12% of P3 relative to the total volume. In non-illustrated variants, the relative percentages of compositions P1 and P3 may be different, for example substantially equal to and less than the percentage of P2. In the example illustrated in FIGS. 1J and 2J, the distributed combination comprises approximately 9% by volume of composition P1, for example an anti-aging agent, forming stripes 11 at the periphery of the outlet bead 81, approximately 58% by volume composition P2 for example a foundation, and about one third by volume of composition P3, for example a day cream, the compositions P2 and P3 forming concentric layers. Figures 1K and 2K illustrate a mixture of three compositions in substantially equal percentages by volume. The device according to the invention can use various containers known from the prior art, in particular for the distribution of dentifrices. Preferably, the device according to the invention comprises a container known from the prior art, for example a flexible tube, in particular of plastic or metal material, for example aluminum, or a rigid or semi-rigid cylindrical tube, provided with a pump and a piston. A variant, devoid of an internal chimney, corresponding to the device of FIGS. 1A and 2A is illustrated in partial section FIG. 3. The composition P1 occupies in the inner volume 8 of the tube a region corresponding to four longitudinal strips, parallel to the X axis The composition P2 occupies the region 20 and is in contact with P 1 without the two compositions being mixed together.

Conventionally, the filling systems used to fill containers of several compositions are provided with a removable nozzle adapted to the choice of compositions and the distribution that is to be obtained inside the filled containers. Such a nozzle comprises a tubular body 150 along an axis Z and a plurality of channels parallel to the longitudinal axis Z of the nozzle, intended for filling with the various compositions.

This same nozzle can also be used to fill non-illustrated devices, for example to fill a container with two compositions, a composition injected through the channels 110 ', 120 and 130' and a second injected through the channels 110, 130 and 120 'if it is desired to have an even distribution between the compositions, or for a composition combination of two-thirds / one-third using the channels 110 and 110' for a first composition and the channels 120, 120 ', 130, 130' for a second composition. The nozzle shown in Figure 5J has two concentric channels 120 and 130 formed by two tubes 125 and 135 concentric with the body 150 of the nozzle and four peripheral channels 110, 120 '. The tube 135 is connected by several groups of four bridges 170 to the tube 125. To fill the device illustrated in Figures 1J and 2J, a first composition P1 is injected through the channels 110, a second composition P2 is injected through the channels 120 and 120 'while a composition P3 is injected through the channel 130.

Viscosity: from 30 UD M4 to 75 UD M4. The formula I is darker than the formula IL These formulas have been combined in proportions 50/50 relative to the total volume, packaged in a tube, type of flexible toothpaste tube, having an internal chimney and without pump, as in the variant illustrated in Figure 7. The container 2 is in the form of a flexible tube having an inner chimney 5 communicating with the dispensing orifice 4 and the second region 20 containing the second composition P2 (anhydrous foundation of the example 2). The first composition P1 (emulsion foundation of Example 1) is contained in a first region 10 formed by an annular space around the chimney 5. The first and second compositions are superimposed along the longitudinal axis of the tube. The chimney 5 extends below the initial level of the first composition Pl. When the user presses the tube, the second composition P2 is pressurized and forced to flow through the orifice 4. The first composition P1 is also pressurized by the second composition P2 and flows through them. passages 6. During the distribution, the chimney 5 is filled with the second composition P2, except for peripheral lines of composition Pi. In the example illustrated, the passages 6 are prolonged by ribs 7 inside the chimney, facilitating the output of the compositions in the form of a regular pattern.

This gives a makeup result combining the cosmetic properties (freshness of the emulsion of formula 1 and sliding and comfort with the application of formula 2) and color (complementary shades of formula 1 and formula 2) for an optimized makeup result.
