Abstract

Container/applicator comprising a reservoir (2) for the product (P) and an applicator (5) such as a circular sponge which picks up the product. The applicator is located inside a compactor (3) which compresses the product on the applicator's surface so that the product is retained until applied to the skin. The compactor and applicator are covered by a removable cap (4).

Description

The present invention relates to the packaging and distribution of a composition in the form of a powder, as used in particular in the make-up and / or care of the skin and mucous membranes, and particularly in the field of face and skin makeup products, such as eyeshadows, blushes, face powders and body.

Recently, powders sometimes appearing on the market have appeared "liquid powders". Such powders include a) a "dry" phase or pulverulent, optionally comprising a binder, and generally consisting of base of pigments and / or nacres and / or fillers and / or glitter, and / or mixing them, and b) a phase, which can in particular act as a binding phase, and containing, inside micro-capsules, vesicles, micro-sponges, waxes porous, or any other structure capable of storing a fluid, such as water, propylene glycol, oil, gel, or an O / W or W / O emulsion, and releasing said fluid, especially in response to pressure. On application, in spreading and pressing the powder against the skin, for example via an applicator, the liquid in the vesicles or microcapsules is released, causing a pleasant feeling of freshness on application.

An example of such a structure capable of storing water is described in the context of a whitening powder, which is the subject of patent application EP-A-0 855 177. According to this request, the whitening powder contains , in addition to the ingredients with a whitening effect, 0.1 to 7% by weight of trimethylsiloxylated silicic acid in anhydrous form, having a specific surface of at least 80 m ² / g, and a degree of hydrophobicity of at least 50 %. Thus, the water retained by the silicic acid in anhydrous form is released by spreading and pressing the powder against the surface to be treated, so that the powder literally liquefies.

Such powders, especially when they are in a continuous aqueous phase, moisturize the skin and do not provide a tightening or drying effect. They have an excellent dispersion of pigments. The composition obtained is also very homogeneous, and remains so even after application to the skin, and this for several hours.

Such compositions also have excellent cosmetic properties: they adhere enough to the skin but not too much; they are very soft, and apply easily. They do not transfer nor do they migrate in the folds of the skin.

A problem which arises with these powders is essentially due to their handling, and their application in particular by means of an applicator. Indeed, with this type of powder, when removing the powder, the pressure exerted by the applicator on the product should not be too high so as not to release the fluid in advance. However, it must be sufficient to allow anchoring the product on the applicator. In addition, a metered sample of the product does not can't be done.

Typically, such powders are packaged in a receptacle topped a sieve through which the powder is brought to pass, the sampling by means of an applicator, in the form of a puff, which is put in engagement with the powder on the sieve so as to withdraw the powder. In because of the difficulty in metering the pressure exerted on the powder via the applicator, it compaction of the powder on the sieve often occurs, causing clogging of the pores of the latter.

In addition, the pulverulent phase tends to "fly" during application.

Finally, when the withdrawal of such a composition is carried out in certain conditions, the particles containing the fluid can agglomerate with the pulverulent compounds to form a kind of heterogeneous and unstable paste which use as a makeup product is not possible

It is therefore one of the objects of the invention to produce a set of conditioning and application of a composition formed at least in part from particles containing a fluid, and solving all or part of the problems discussed above with reference to certain conventional devices,

It is in particular an object of the invention to provide such an assembly which allows easy, metered and homogeneous application of such a product, avoiding in particular the phenomena of compaction or early release of the fluid, mentioned above.

Still other objects will appear in the detailed description which follows.

Quite unexpectedly, the plaintiff discovered that when a such composition was packaged and distributed by means of a set having particular characteristics, the handling of such composition, and in particular its sampling and spreading, is done so much more satisfying.

According to the invention, these objects are achieved by producing an assembly for the conditioning and application of a composition, in particular a cosmetic composition, said composition composition being placed inside a tank and being formed at least in part, of particles containing at least one fluid, said assembly comprising a applicator formed by a gripping element and an application element with at least part of which the composition in the tank is intended to come in contact, said applicator being configured so that, during a movement, along a substantially predetermined path, of the applicator by report to said reservoir, at least the part of the application element with which the composition has been brought into contact, passes through a compacting member, and comes into engagement with at least a portion of it, the pressure acting between the application element and said portion (s) of the member compaction during said engagement, favoring the anchoring of the composition on said application element.

According to the present invention, the particles containing at least one fluid are particles formed of a hollow or porous structure, capable of storing a certain quantity of said fluid, and to release it, in response to sufficient pressure, corresponding in particular to the pressure resulting from the application of the composition on the surface to be treated. In other words, in the reservoir that contains (possibly mixed with a pulverulent phase), both phases forming said particles ("solid" phase forming the container, and the fluid phase contained within the "solid" phase) remain individualized, one being contained within the other. However, in response to said pressure, the liquid is expelled from the structure that contains it, and is released on the surface to be treated. The liquid thus released can be brought into contact, if necessary, with a powdery phase to promote spreading and staying on the skin.

The fluid can be contained inside vesicles, micro- or nano-capsules, micro-sponges, microspheres, or any other porous structure. The fluid may in particular be water, a gel, an oil, polypropylene glycol, a O / W or W / O emulsion.

In the following description, the phase consisting of the particles containing the fluid, in whatever form, will be referred to as the "liquid phase". The sentence liquid of the composition promotes, if necessary, the attachment of the phase pulverulent on the surface to be treated, and also promotes its spreading. She can be advantageously used as a vehicle for at least one active principle, especially for skin care. It also gives a fresh effect on the skin.

Of the predetermined path of the applicator element passing through the compaction of the applicator, it follows that the pressure applied by the compaction on the application element remains substantially the same throughout of the service life of the system, and can be set to be strong enough to allow adequate anchoring of the product on the applicator, and low enough not to cause early release of the fluid stored. When the applicator element passes through the compaction, this also results in a homogeneous spreading of the composition taken from the effective part of the application element, which spread homogeneous promotes spreading of the product on the surface to be treated, in particular the skin.

Preferably, the predetermined path is in a direction other than a direction perpendicular to the application surface, so as to limit the crushing of the powder on the applicator. Thus, preferably, one causes a relative displacement between the compacting member and the application surface, substantially in the plane of the application surface or in a plane tangential to the surface of application.

Advantageously, said compacting member is fixedly mounted in the vicinity a tank opening.

The substantially predetermined movement of the applicator relative to the tank can be a rotational movement around an axis, or a movement of translation substantially along an axis.

The application element is preferably, on at least part of its surface, covered with a flock coating. Such flocking can consist of fibers of cotton or rayon. The fibers can be of length and / or of section, and / or different in nature, depending on the application characteristics wanted.

According to an advantageous embodiment, all or part of said element application is made in particular of closed cell foam, open or semi open, in thermoplastic or vulcanized elastomer, in particular in polyester, polyethylene or polyvinyl chloride elastomer, in sintered form, especially metal or ceramic, or felt.

The assembly according to the invention is preferably configured so that a volume air is formed between a free surface of the composition, and the compaction. As an indication, the assembly is configured so that, before the first use, the composition occupies only half the height of the container. Such a volume makes it possible in particular, by agitating the assembly, to homogenize the product contained in the tank, especially when the product contains particles with different densities, and possibly ensuring bringing the product into contact with the application element in the event that this the latter is not "immersed" in the product.

Preferably, in a position mounted by the applicator on the reservoir, the application element is disposed between said free surface of the composition and the compacting member, bringing the application element into contact with the composition made in particular by agitating the whole. This avoids the compacting in the reservoir of the composition by the application element.

According to one embodiment, the application element is of cross section circular, and mounted in rotation inside a casing surmounting the reservoir, said casing constituting said compacting member, and having at least two openings, a first opening arranged opposite the tank and through from which, in a first angular position, a segment of the element of application emerges so as to be brought into contact with the composition, said segment of the application element being able to pass from said first position to a second position in which it emerges through a second opening leading to the outside of the tank so as to allow the application of all or part of the composition with which it was put contact in the first position, said first and second openings being separated by at least a portion of the housing with which, passing from the first to second position, said segment is engaged for cause the composition to be applied to all or part of the surface to anchor of said segment.

Such a device is described in detail in French patent FR 2 701 364.

Advantageously, the transition from the first to the second position is done by a rotation of the applicator element about an axis perpendicular to its section transverse. The applicator can be actuated from the outside by the user. of preferably, the actuating device consists of at least one thumb wheel fixed to one end of the axis of rotation and arranged at least partially at the outside of the housing.

According to another embodiment, the compacting member consists of a element formed from at least one foam material, and disposed in the vicinity an opening of the reservoir, said element being traversed by at least one slot or a passage so that it can be crossed by said application element. Such a device is described in detail in patent application WO 97/31553.

The application element may be integral with a first end of a rod, a second end of the rod, opposite the first being integral with an element able on the one hand to form a gripping member for said application element, and secondly, when said applicator is mounted on the reservoir, to be closed off sealing said opening.

Preferably, in the absence of the applicator, the edge (s) delimiting said slot or said passage are substantially contiguous.

More preferably still, in the mounted position of the applicator on the reservoir, said application element is located between the compacting member and a bottom of the tank, preferably between the compacting member and the free surface of the composition, a portion of said rod being disposed in said passage or said slot, said rod being configured so that said rod portion does not compress not sensibly said foam element.

The foam may be a foam formed at least in part of cells open or semi-open, in particular a foam of an elastomer, in particular polyurethane or polyether. Preferably, the foam comprises so generally at least 5% open cells, cells with a diameter of preferably between 5 µm and 3 mm. The height of the foam block 11 is typically between 1.5 mm and 80 mm.

The foam block can be stiffened at its periphery and on at least part of its height, in particular to prevent it from compressing during the introduction of the applicator in the container.

The compacting member can be formed by the union of two half-cylinders full of foam, held against each other by the neck of the container and defining between them a slit which can open when the element passes of application.

In another variant, the compacting member can be produced by winding a strip of foam on itself, defining a central recess for the passage of the application element. The compacting member can also be made by superimposing several plain foam washers different, made in foams with cell densities increasing as we get closer to the outlet of the container, the whole being traversed by an axial recess for the passage of the application element.

The compacting member can be retained in many ways in the container. The foam block can be simply glued or welded on its periphery to the wall of the container.

The compositions according to the invention preferably comprise a phase pulverulent, mixed with the liquid phase, and can be formed of pigments and / or nacres and / or fillers and / or glitter usually used in cosmetic compositions, and / or their mixtures. The particles forming the pulverulent phase can also be coated with a binder.

By pigments, we must understand white or colored particles, mineral or organic, insoluble in the medium, intended to color and / or opacify the composition.

The pigments can be white or colored, mineral and / or organic, of size usual or nanometric. Mention may be made, among the pigments and nanopigments minerals, titanium, zirconium or cerium dioxides, as well as oxides zinc, iron or chromium, nanotitanes, nanozincs, ferric blue. Among the organic pigments, there may be mentioned carbon black, and lacquers such as calcium, barium, aluminum or zirconium salts, dyes acids such as halo-acid, azo or anthraquinone dyes.

The pigments can in particular be coated with silicone compounds such as as polydimethylsiloxanes and / or by polymers, in particular polyethylenes. We can thus cite the pigments SA or SI sold by the company Maprecos.

By charges, it is necessary to understand colorless or white, mineral particles or synthetic, lamellar or non-lamellar, intended to give body or stiffness in composition, and / or softness, mattness and uniformity in makeup.

The fillers can be mineral or synthetic, lamellar or not lamellar. Mention may be made of talc, mica, silica, kaolin, nylon powders, poly-β-alanine and polyethylene, Teflon, lauroyl-lysine, starch, nitride boron, bismuth oxychloride, polymer powders tetrafluoroethylene, polymethylmethacrylate powders, powders polyurethane, polystyrene powders, polyester powders, synthetic hollow microspheres such as Expancel (Nobel Industrie), micro sponges such as polytrap (Dow Corning) and resin microbeads silicone (Tospearls from TOSHIBA, for example), zinc oxides and titanium, zirconium or cerium oxides, precipitated calcium carbonate, magnesium carbonate and hydrocarbon, hydroxyapatite, hollow silica microspheres (Silica Beads from the company MAPRECOS), glass or ceramic microcapsules; metallic soaps derived from acids carboxylic organic having from 8 to 22 carbon atoms, preferably of 12 to 18 carbon atoms, for example zinc stearate, magnesium or lithium, zinc laurate, magnesium myristate.

By pearlescent, we must understand iridescent particles that reflect light.

Among the possible nacres, one can cite natural mother-of-pearl, covered mica titanium oxide, iron oxide, natural pigment or bismuth oxychloride as well as colored titanium mica.

The compositions according to the invention can also comprise flakes.

The powder of the invention can also comprise any additive commonly used in the relevant field of antioxidants, essential oils, preservatives, neutralizers, W / O or O / W surfactants, vitamins, anti-wrinkle active ingredients.

The fluid in the liquid phase is in the form of water, polypropylene glycol, oils, especially essential oils, gel, especially particles cubic gel, water in oil emulsion (W / O) or oil in water (O / W).

The fluid can be contained in vesicles or microcapsules, the walls of which are in particular made of epoxy, polyethylene, gelatin or polyester, or in micro sponges or microspheres. The fluid can also be contained in porous waxes such as polyacrylates.

The fluid, especially in the case of water, can be contained in a structure anhydrous of the type described in patent application EP-A-0 855 177, to which was previously referred to. As another example, the phase "liquid" includes an aqueous dispersion of vesicles consisting of lipid phase membrane encapsulating an aqueous phase. The vesicles usable according to the present invention can also be provided with a lamellar liquid crystal coating.

Preferably, the composition contains at least one active ingredient. Such an asset can be hydrophilic, lipophilic, or a mixture of both.

• la figure 4 illustre un ensemble selon un second mode de réalisation de l'invention.

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:

• Figures 1-3 illustrate an assembly according to a first embodiment of the invention; and
• FIG. 4 illustrates an assembly according to a second embodiment of the invention.

The applicator assembly shown in Figures 1 to 3 is designated in its together by reference 1. It consists of a tank 2, a casing 3 and a removable cover 4. The casing 3 rotates around a spindle 6 a disc applicator 5. The reservoir 2 is a cylinder of almost rectangular cross section by two parallel parallel side walls 21 and forming an opening 99 at its the top part. The edge of the tank is provided with a fixing device 22 by breakdown, cooperating with a corresponding device 35 of the casing 3. The reservoir contains a powder P for making up the cheeks, of the type described previously. In this particular example, the liquid phase comprises wax microcapsules containing water.

The casing 3 is constituted by an envelope 31 whose side walls are in line with those of tank 2. In this case 3 a cylindrical space is provided, of circular section coaxial with the disc applicator 5 and axis 6, having dimensions allowing it to closely fit the shape of the applicator disc 5. On the lower edge of the casing 31 of the casing, an interior opening 32 is made which places the reservoir 2 in communication with the inner cylindrical space of the casing 31 of the casing 3. This opening 32 includes notches, formed in the flat side walls of the envelope 31, which have a trapezoidal shape. All around the opening 32, the edge 32a has the shape of a bevel inclined from the outside towards the inside. At his upper part, the casing 3 has an outer opening 33 of form rectangular. In the envelope 31 are formed two circular windows 34a and 34b for the passage and fixing of the axis of rotation 6 of the applicator disc 5, as explained below. Inside the wall of the envelope 31, these windows 34a, 34b consist of two sections of different diameters, separated by a shoulder, the section of smaller diameter opening into space cylindrical with circular section. On the upper part of the housing, around the outer opening 33 is provided with a device for fixing the cover 4 consisting of a breakdown device 36 cooperating with a device corresponding 41 of the cover 4.

The applicator disc 5 is, in the embodiment shown in Figures 1 to 3, entirely in flexible, fully flocked foam. It is provided in its center a circular opening 51 for the passage of the axis 6. The disc 5 has dimensions such that, when mounted in the casing 3, a segment 52 emerges of the casing 3 through the opening 33 and that a segment 53 of the disc is disposed in the opening 32 to the right of the trapezoidal notches.

The axis 6 consists of two elements 6a and 6b which fit into each other. Each of these elements is made up of three successive sections decreasing: a dial 61a, 61b of circular cross section, a flange 62a, 62b of circular cross section and a rod 63a, 63b. Rod 63a of the element 6a is solid and has, in cross section, a square shape. She fits into the hollow rod 63b which has an imprint having a section square corresponding to that of the rod 63a. The fixing of the rod 63a in the rod 63b is done by a double rib system 64a and breakdown groove 64b. The flanges 62a and 62b carry axial pins 65a and 65b which sink into the flexible foam constituting the disc 5 and which prevent any relative rotation of the disc 5 relative to axis 6 when the assembly is mounted. The flanges 62a and 62b are partially arranged in the section of smaller diameter of the windows 34a and 34b. The knobs 61a and 61b are partially arranged at the outside of the windows 34a, 34b in the section of larger diameter of said windows and rest on the shoulder between the two diameter sections different from windows 34a and 34b. Thus, when the two elements 6a, 6b are nested, the axis 6 is positioned and retained axially; the knobs 61a and 61b are provided externally with four notches 66a facilitating the manual action of the user on each wheel.

The cover 4 is fixed on the upper part of the casing 3, so as to protect the segment 52 of the applicator member 5 emerging from the opening 33 of the casing 3; the cover 4 has on its faces extending the parallel walls 21 of the tank 2 of the notches 42 in an arc of circle in which the knobs 61a, 61b in the closed position of the cover 4.

Set 1 works as follows. When the user wishes to withdraw for example a powder P contained in the reservoir 2, it removes the cover and returns the assembly 1, or shakes it vigorously, so that the powder P comes in contact with segment 53 of disc 5. Then, it turns one of the knobs 61a or 61b by half a turn, in one direction or the other, so that the part of the disc forming the segment 53 takes the place corresponding to the segment 52 in the opening 33. During the rotation, the powder is compacted by the edges inclined 32a, between which the disc is driven, then thereafter by the surface inside of the casing 31. The product is thus compacted on the applicator 5 and is evenly distributed over segment 53, a small amount of liquid possibly having been released during this compaction on the applicator. At final, the pulverulent phase does not fly. To apply the powder, the user serves as the segment emerging from the casing 3 as an applicator.

On application, by pressing the applicator on the skin, the liquid contained in the wax microcapsules is released, and mixes with the pulverulent phase, which gives an impression of freshness on the skin, and promotes spreading and hold powder on the skin.

Thanks to the elasticity of the periphery of the foam disc 5, the contact between the disc 5 and the edge of the opening 32 is sufficiently tight so that the powder does not risk escaping from the tank during storage and when returns the assembly to bring the product into contact with segment 53 of the disk.

FIG. 4 shows a device 100 according to a second example for carrying out the invention. This device, of axis X, comprises a container 188 and a applicator 189. The container 188 is formed by assembling a part lower 190 and an upper part 191. The lower part 190 has a central tubular wall 192 closed below by an attached bottom 193 and surmounted by a neck 154. The neck 154 ends in a flange 195 forming radially projecting inward.

The powder P is contained inside the tubular wall 192, and on its surface free disposed substantially halfway up the tubular wall 192. The phase powder consists of pigments and fillers for making up lips. The liquid phase is formed on the basis of polypropylene glycol retained in wax micro-capsules melting at low temperature.

The upper part 191 of the container 188 has a central tubular wall 196 extended radially outwards, near its end upper, by an external skirt 197 which is rounded down and on the surface internal of which snaps the external skirt 194 of the lower part 190. The tubular central wall 196 then engages sealingly on the neck 154 of the tubular part 192.

A hoop 198, molded with the upper part 191 of the container, is articulated on the outer skirt 197 by means of bridges of material 199 forming hinges. The central tubular wall 196 has, at the connection of the outer skirt 197, a recess 150 inwards, extended upwards by a collar 101 delimiting an opening 121. The applicator 189 comprises a gripping member 102, extended downward by a rod 103 provided at its lower end of an application element 104. The application element 104 is made of an elastomeric pallet, with an ovoid longitudinal section, and shaped tapered towards its free end. Application element 104 is covered with a flock coating. The gripping member 102 is formed by the assembly of an external body 105, of ogival shape, open at its end lower part and an internal part 106 fitted into the external body 105 and having a hollow housing 107 in which a spherical head 108 is retained formed at the upper end of the rod 103, so as to constitute a ball joint.

In the closed position of the container 188, the external body 105 of the gripping 102 adjusts to the collar 101. The seal on closing is obtained by the tightening of the internal part 106 against the upper end edge of the neck 101. The rod 103 of the applicator 189 widens at its lower end 109 to form a housing for fixing the application element 104, consisting in the example described by a felt tip.

A block of polyurethane foam 110 is housed inside the tubular wall central 196, being retained axially at its lower end by the flange internal 195 and at its upper end by the hook 100. The block of foam is traversed by an axial passage 120.

Upon application, the user shakes the assembly 100, so as to bring the powder P in contact with the application element 104, arranged at a distance from the free surface of the powder. The product is deposited both on the applicator and on the bottom wall foam block 110. By extracting the applicator 189 from the reservoir 188, the element application is brought through the foam block 110, via the passage 120, along a path substantially along the X axis, imposed by the configuration of all. In doing so, the powder present on the application element 110 is pressed between the applicator surface and the foam block, thereby improving the powder hold on the applicator. Also, when extracting the item 104, via the passage 120 of the foam block 110, the lower wall of the foam block is driven by the application element 104, and rises in inward part of the foam block, causing transfer to the powder applicator present on said lower face.

At the exit of the application element 104, the powder is firmly anchored on the applicator. She does not fly. When applied to the skin, the pressure applied by the applicator on the skin, releases the trapped liquid in the micro-capsules of wax, which liquid gives a pleasant feeling of fresh and soft, and helps promote spreading and good hold of the powder on the skin.
