Abstract

Make-up and/or care kit for eyelash comprises: two cosmetic compositions (I) and (II), where both compositions contain a continuous oil phase and the dry weight of the second composition is >=2% than the first composition; and an applicator having fringes (6) arranged on a support (5) in a row wise. Independent claims are included for: (1) a make-up and/or non-therapeutic process of eyelashes comprising applying the compositions simultaneously using the applicator; and (2) a support comprising the make-up compositions.

Description

The present invention relates to a kit for makeup and / or care of the eyelashes comprising at least two cosmetic compositions for makeup and / or care of the eyelashes (or mascaras), one of the compositions being a loading composition, the kit comprising a means of application allowing an application of said loading cosmetic composition on only a portion of the eyelash fringe, and in particular on at most the outer third of the eyelash fringe.

There is a need to obtain new makeup effects on the eyelashes and in particular to deposit mascara more pronounced on only a portion of the eyelash fringe.

With the aid of a conventional brush or comb type applicator, it may be difficult to make a precise material deposit on only a portion of the eyelashes, while avoiding the formation of clusters.

It may indeed be interesting, to obtain particular makeup effects, to play on deposits of contrasting material on disjoint areas of the eyelash fringe.

The inventors have found that a greater makeup of a portion of the eyelashes, in particular a large deposit of material on at most one-third of the eyelash fringe, and more particularly, on the outer part of the eyelash fringe, provides a particular makeup result that opens the eye and enlarges the eye, optically modifying the perception of the shape of the eye. Such makeup having a greater material deposit on at most a third of the fringe, on the outside of the fringe, gives an impression of almond shaped eye and stretched eye, the outer corner is reassembled ( "lifting" effect of the gaze).

The invention therefore provides a means for easily achieving this particular makeup goal.

• la composition (ii) présente un extrait sec supérieur à 42% en poids par rapport au poids total de la composition,
  et en ce qu'il comprend un moyen d'application sur la frange de cils, comportant une pluralité d'éléments d'application (6 ; 60) disposés sur un support (5) sous forme d'au moins une rangée dont la longueur est telle que les éléments d'application (6 ; 60) puissent au mieux contacter simultanément au plus un quart des cils de la frange.

The subject of the present invention is therefore, in one of its aspects, a kit for makeup and / or care of the eyelashes comprising at least two cosmetic compositions for makeup and / or care of the eyelashes (i) and (ii), characterized in that than :

• at least one of said compositions (i) and (ii) comprises a continuous oily phase,
• the difference between the dry extract of the composition (ii) and the dry extract of the composition (i) is greater than or equal to 2% in absolute value, preferably greater than or equal to 3% and in that it comprises an application means on the eyelash fringe, comprising:
  • a plurality of application elements (6; 60) arranged on a support (5) in the form of at least one row whose length is such that the application elements (6; 60) can at best simultaneously contact the more than a quarter of the eyelashes of the bangs.
  The subject of the present invention is also, according to one of its aspects, a kit for makeup and / or care of the eyelashes comprising at least two cosmetic compositions for makeup and / or care of the eyelashes (i) and (ii), characterized in that than
• at least one of said compositions (i) and (ii) comprises a continuous oily phase,
• the composition (i) has a solids content of less than or equal to 42% by weight relative to the total weight of the composition,

The inventors have thus observed that the application on the eyelashes of the composition (i) and of the composition (ii), at least one of which is applied by means of this particular application means, and more preferably the composition (ii), makes it possible to easily perform a more volumizing deposit or loading on only a part of the eyelash fringe, for example on at most the outer third of the eyelash fringe.

In particular, the composition (i) provides a smooth and homogeneous deposit, easy to apply, which sheaths, separates and / or lengthens the eyelashes. The composition (i) makes it possible to obtain a make-up that is not very filling, that is to say that it does not thicken the eyelashes: a natural make-up is thus obtained. It is thus easy to perform, on this first makeup film, a more volumizing deposit or loading on only a part of the eyelash fringe, for example on at most the outer third of the eyelash fringe by application of the composition (ii) which, because of its total content in dry matter waxes, makes it possible to obtain a larger deposit of material.

Thus, this kit makes it possible to accentuate the contrast between the makeup provided by the deposition of the composition (i) and that provided by the deposition of the composition (ii), while avoiding the formation of "packages" deemed unsightly.

Characterization of the dry matter content

For the purpose of the present invention, the "dry matter content" denotes the content of non-volatile matter.

This quantity of dry matter, commonly referred to as "dry extract" or in abbreviated form ES, of the compositions according to the invention can be calculated (theoretical ES) or can be measured by heating the sample by infrared rays of 2 μm to 3.5 μm wavelength. The substances contained in said compositions which have a high vapor pressure, evaporate under the effect of this radiation. The measurement of the loss of weight of the sample makes it possible to determine the "dry extract" of the composition. These measurements are made using MRLLER's "LP16 ^® " commercial infrared desiccator. This technique is perfectly described in the documentation of the device supplied by Mettler.

• On étale environ 1g de la composition sur une coupelle métallique. Celle-ci, après introduction dans le dessiccateur, est soumise à une consigne de température de 120 °C pendant une heure. La masse humide de l'échantillon, correspondant à la masse initiale et la masse sèche de l'échantillon, correspondant à la masse après exposition au rayonnement, sont mesurées au moyen d'une balance de précision.

The measurement protocol is as follows:

• About 1 g of the composition is spread on a metal cup. This, after introduction into the desiccator, is subjected to a temperature of 120 ° C for one hour. The wet mass of the sample, corresponding to the initial mass and the dry mass of the sample, corresponding to the mass after exposure to radiation, are measured using a precision balance.

The dry matter content is calculated as follows: $$\mathrm{Dry\; extract}=100\times \left(\mathrm{dry\; mass}/\mathrm{wet\; mass}\right)\mathrm{.}$$

The values measured using the protocol described above may differ from the corresponding theoretical values by plus or minus 1%.

The compositions (i) according to the invention may have a solids content of less than or equal to 42% by weight relative to the total weight of the composition, preferably less than or equal to 41% by weight, better still less than or equal to 40% in weight.

The measurement protocol is as follows:

The wax is melted at a temperature equal to the melting point of the wax + 10 ° C. The melted wax is poured into a container 25 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25 ° C) for 24 hours so that the surface of the wax is flat and smooth, then the wax is kept for at least 1 hour at 20 ° C before measuring. tights.

The mobile of the texturometer is moved at a speed of 0.5 mm / s, then penetrates into the wax to a depth of penetration of 2 mm. When the mobile penetrated the wax to the depth of 2 mm, the mobile is held stationary for 1 second (corresponding to the relaxation time) and then removed at a speed of 0.5 mm / s.

During the relaxation time, the force (compression force) decreases sharply until it becomes zero and then, when the mobile is removed, the force (stretching force) becomes negative and then increases again to the value 0. The pantyhose corresponds to the integral of the force vs. time curve for the part of the curve corresponding to the negative values of the force (stretching force). The value of the sticky is expressed in N.s. The tacky wax that can be used generally has a hardness of less than or equal to 3.5 MPa, in particular ranging from 0.01 MPa to 3.5 MPa, in particular ranging from 0.05 MPa to 3 MPa, or even from 0 to 1 MPa at 2.5 MPa.

Such a wax is especially sold under the names "Kester Wax K 82 P®" and "Kester Wax K 80 P®" by the company Koster Keunen.

The waxes mentioned above generally have an initial melting point below 45 ° C.

It is also possible to use the microcrystalline wax marketed under the reference SP18 by the company Strahl and Pitsch, which has a hardness of approximately 0.46 MPa and a tack value of approximately 1 N.s.

The wax (es) may be present in the form of an aqueous microdispersion of wax. By aqueous microdispersion of wax is meant an aqueous dispersion of wax particles in which the size of said wax particles is less than or equal to about 1 μm.

Microdispersions of wax are stable dispersions of colloidal particles of wax, and are especially described in " Microemulsions Theory and Practice, LM Prince Ed., Academic Press (1977) pages 21-32 .

In particular, these microdispersions of wax can be obtained by melting the wax in the presence of a surfactant, and optionally a portion of the water, and then gradually adding hot water with stirring. The intermediate formation of a water-in-oil emulsion is observed, followed by a phase inversion with final obtaining of an oil-in-water type microemulsion. On cooling, a stable microdispersion of solid colloidal particles of wax is obtained.

The microdispersions of wax can also be obtained by stirring the mixture of wax, surfactant and water using stirring means such as ultrasound, the high-pressure homogenizer, the turbines.

The particles of the microdispersion of wax preferably have average dimensions of less than 1 μm (in particular ranging from 0.02 μm to 0.99 μm), preferably less than 0.5 μm (in particular ranging from 0.06 μm to 0 μm). , 5 μm).

The device 1, shown in FIG. 1, which corresponds to part of the kit when the latter is packaged in two separate packages, comprises a container 2 containing a reserve of a cosmetic product P, in this case one of the compositions ( i) or (ii), and an applicator 3 comprising a rod 4 of longitudinal axis X. Only the device comprising the application means according to the invention and one of the compositions according to the invention is represented here.

The rod 4 is provided at one end with a support 5 having a plurality of application elements 6 and the rod 4 is connected to the end opposite to a closure cap 7 of the container 2 which also constitutes a gripping element .

The closure cap 7 has an unseen internal thread intended to be screwed on the neck 11, threaded externally, of the container 2.

The container 2 comprises, in the example described, a wiper member 8 engaged in the neck 11 and having a wiper lip 9 arranged to dewater the rod 4 and the support 5 provided with the application elements 6.

The wiper member 8 can, if necessary, be arranged in such a way that it can deform in the passage of the application elements 6.

The wiper member 8 may be made by injection molding, for example in a polyolefin.

The container 2 is sealed in the absence of use by screwing the closure cap 7 on the neck 11.

In the example shown, the applicator 3 comprises a comb, the application elements 6 being constituted by teeth. The support 5 extends along a longitudinal axis Y forming with the longitudinal axis X of the rod 4 a non-zero angle α, as illustrated in FIG. 3 in particular. This angle α may be between 5 ° and 45 ° for example.

The application elements 6, six in number for example, are arranged in the example under consideration in a row 10.

The application elements 6 can be located on the support 5 in various configurations.

In the example shown, the row 10 comprises a first series of teeth 6a and a second series of teeth 6b respectively located on either side of a geometric separation surface S, which is here a median plane of symmetry of the comb, parallel to the plane of Figure 3, and may also constitute a joint plane for molding the comb.

In the illustrated example, the teeth 6a and 6b are made alternately on either side of a common core 15 of the support 5, which serves as a sort of skeleton on which the teeth are connected in the lower part.

The support 5 is provided at the front with a rounded nose 17, intended to facilitate its retraction into the receptacle 2.

The support 5 comprises, at the rear, a boss 18 intended to facilitate the crossing of the wiper member 8 during its extraction from the container 2.

The application elements 6 each comprise an upper part 20 ending in a free end 30 and a lower part 22 connected to the core 15 of the support 5.

In the example considered, the application elements 6 extend substantially perpendicular to the Y axis of the support 5.

The free ends 30 of the application members are at a distance from the longitudinal axis Y varying non-monotonously as one moves between the extreme application elements of the row 10, from left to right on the figure 3.

In the illustrated example, the line L connecting the free ends 30 has, when the applicator is viewed from the side, in a direction perpendicular to the longitudinal axis of the rod 4 and the aforementioned geometric separation surface, as shown in FIG. Figure 3, a substantially triangular shape, with two straight segments forming between them an angle substantially equal to 90 ° in the drawing.

In the example considered, the succession of application elements 6 comprises two larger teeth 6a and 6b of the same length.

The straight line D ₁ passing through the free end of the element of smaller length starting from the distal end of the applicator and through the free end of the element of greatest length closest to this element of smaller length is confused in this example with the first rectilinear segment of line L.

The angle γ ₁ formed between the line D ₁ and the perpendicular N ₁ to the Y axis passing through the free end of the application element of greater length mentioned above is for example between 25 ° and 60 °, being for example about 43 °.

The line D ₂ , passing through the smallest application element from the proximal end of the support 5 and the largest application element closest to this element is merged with the second rectilinear segment of the line L.

The angle γ ₂ formed between the line D ₂ and the perpendicular N ₂ to the Y axis passing through the free end of this larger application element can be included in the same ranges of value as the angle γ ₁ , being for example substantially equal to γ ₁ . The apex angle between the segments of the line L is for example less than or equal to 120 °, or even less than or equal to 90 °.

The application elements 6 extend over the support 5 over a relatively small distance d, in particular a distance d of between 0.1 and 1 cm approximately. Thus, as illustrated in Figure 2, it is possible, using the applicator 3, to make up only a portion of the eyelash fringe at a time without reaching all the eyelashes of the eyelid. For example, the application elements can simultaneously contact, at most, less than a quarter of the eyelashes of the upper eyelid, as illustrated.

The support 5 and the application elements 6 are made in one piece in the illustrated example, by plastic molding. The support 5 is attached to the rod 4 in a manner which will be detailed below with reference to FIGS. 10 and 11.

In the example described, the upper portions 20 of two consecutive application elements 6 provide between them a notch 21 extending substantially to the core 15, when the comb is viewed from the side, as in FIG. The notches 21 make it easier to grasp the eyelashes, for example to separate, comb or smooth the product deposited on their surface.

It is understood that by varying the length of the application elements and the interval between them, it is easy to act on the amount of product that the applicator loads.

The difference between the vertices of two successive application elements 6a or 6b situated on one and the same side of the geometric separation surface is in the example considered substantially greater than the width of an application element, measured at half height of the applicator 3, parallel to the axis Y of the support 5.

Each applicator element 6a extends substantially halfway, when the applicator 3 is viewed from the side, two adjacent applicator elements 6b and vice versa.

In the example considered, the upper parts 20 of the application elements 6 point substantially all in the same direction.

The lower portions 22 of two successive application elements located on one and the same side of the core 15 form between them and with the core 15 a cavity 23 which can constitute a reserve of product.

The spacing between the application elements 6a or 6b can be relatively large in favor of the amount of product that the applicator loads without the applicator losing any ability to grip the eyelashes, thanks to the shift of the elements of application and the notches 21 formed by the upper parts 20 of the application elements remain sufficiently narrow.

The application elements 6 may have many configurations without departing from the scope of the present invention, including differently oriented upper parts.

It is not beyond the scope of the present invention when the application elements 6 are arranged differently on the support 5.

FIGS. 5 and 6 show another example of an applicator comprising a plurality of teeth 6, for example seven in number, extending in a row 10. The teeth 6, as can be seen in FIG. Figure 6, have aligned bases 22 while the upper portions 20 of two consecutive teeth 6a and 6b diverge.

FIG. 7 illustrates the possibility of producing the rod 4 with a longitudinal axis X which coincides with that Y of the support 5.

In FIG. 8, the support 5 is represented with a longitudinal axis Y forming a non-zero angle α with the longitudinal axis X of the rod 4, the direction of the inclination of the support in FIG. 8 being opposite to that of the support Figures 1 to 4.

The support 5 can be made in one piece with the rod 4, for example by molding plastics material as illustrated in FIG. 9. But the support 5 can also be attached to the rod 4.

In the example shown in Figure 10, the support 5 comprises a substantially cylindrical nozzle 35 having an annular groove 36. The rod 4 comprises a corresponding housing 37, provided with an annular bead 38 arranged to snap into the groove 36 .

The end piece 35 could still be configured to be force-fitted into the rod 4.

In the example of Figure 11, the rod 4 comprises a substantially cylindrical tip 40, arranged to be housed in a corresponding housing 41 of the support 5.

The applicator 3 may comprise a number of teeth less than six or seven, and in particular comprise only two teeth 6 as illustrated in FIG. 12. The teeth may or may not have the same width.

The line L connecting the free ends 30 of the application elements 6 may have various shapes other than those of FIGS. 1 to 11, as illustrated in FIGS. 13 to 17.

In particular, the line L may have a rounded shape, in particular substantially circular as illustrated in FIG. 13, or ogival as illustrated in FIG. 14. The extremum may be located substantially in the middle of the support 5 as illustrated above, be closer of the rod 4 as illustrated in Figure 15 or closer to the distal end of the applicator as illustrated in Figure 16. The distance of the line L to the longitudinal axis Y of the support 5 can pass by two extrema as illustrated in Figure 17.

It can be seen in FIG. 13 that the support 5 may be devoid of the rounded nose 17 and / or the boss 18.

This figure also shows the straight lines D ₁ and D ₂ and the normal N to the longitudinal axis Y of the support 5 which passes through the free end of the longer application element, which is unique. in the example considered.

The angles γ ₁ formed between the straight line D ₁ and this normal N and γ ₂ formed between the line D ₂ and this normal N can be equal or different, being for example included in the range of values given above.

In the example of FIG. 17, it is possible to define angles γ ₁ and γ ₂ relative to the normal N passing through the free end of the application element associated with the first relative extremum and γ ^' ₁ and γ ^' ₂ relative to the normal N 'passing through the free end of the application element corresponding to the second relative extremum, these angles being again included for example in the range of values given above.

FIG. 18 illustrates the possibility of producing on the support 5 two rows of application elements, for example two rows located opposite one another relative to the core 15 of the support 5. The elements application may extend differently from one row to another and in particular, as illustrated in Figure 18, have different profiles when the applicator 3 is viewed from the side.

The core 15 may present in cross section a circular shape as illustrated in Figures 19, 20 and 22 or other, for example flattened, in particular substantially rectangular, as shown in Figure 21.

The support 5 may comprise a row of aligned teeth, as illustrated in FIG. 19, or several rows of teeth extending in different directions, for example divergent as illustrated in FIG. 20 or in parallel directions as illustrated in FIG. 21.

FIG. 22 shows an applicator comprising a plurality of rows 10, arranged all around the core 15 of the support 5.

The applicator elements 6 may have, when the applicator is observed from the side, over at least a part of their length, a substantially constant width profile, as illustrated in FIGS. 1 to 22. The application elements 6 may still have a different profile, including substantially triangular, as illustrated in Figure 23, or other.

The application elements may be staggered as shown in FIG. 24.

The wiper member 8 may be different from that shown in Figure 1 without departing from the scope of the present invention. FIG. 25 shows a device in which the wiper member 8 consists of a cellular material, in particular an open-cell or closed-cell foam.

The wiper member 8 may alternatively be made of elastomer and comprise at least one slot 50 as illustrated in FIG. 26. The wiper member 8 may comprise an annular lip 51 as illustrated on FIG. Figure 27, except at its lower end.

The application elements may be other than teeth and comprise for example bristles, reported on the support, as shown in Figure 28. The applicator 3 then comprises, for example, a brush whose bristles 60 extend substantially transversely to the longitudinal axis Y of the support, which may be coincident with the longitudinal axis X of the rod 4 as illustrated.

In the example considered, the bristles extend over a distance d along the longitudinal axis Y of the support which is such that the bristles can not simultaneously contact more than a quarter of the eyelashes or eyebrows of the fringe. eyelashes or eyebrows that one wants to make up. The distance d may for example be between 2 and 3 mm, and the number of turns may be between 3 and 6, for example.

When the applicator 3 is viewed from the side, as illustrated in Figure 28, the line L connecting the free ends of the bristles may have a distance to the Y axis which passes through at least one extremum.

When the applicator 3 comprises a brush, the bristles 60 used are preferably relatively thin, for example about 6/100 mm in diameter.

The bristles 60 may have a solid, substantially circular cross section.

The core 61 may be formed by a U-folded wire and whose branches are twisted on themselves so as to clamp the bristles together.

The wire used is preferably relatively thin, for example with a diameter of less than 0.7 mm, in particular between 0.35 and 0.5 mm.

Figures 29 to 35 show alternative applicators.

In FIG. 29, the applicator 3 comprises a brush having a substantially conical or frustoconical envelope surface, the longest hairs being on the side of the rod 4.

The angle δ formed between the perpendicular to the longitudinal axis Y of the brush passing through the larger dimension of the cross section and the tangent to the envelope surface is for example between 20 ° and 60 °.

The applicator 3 of FIG. 30 comprises a substantially biconical envelope surface brush whereas that of FIG. 31 comprises a substantially conical or frustoconical envelope surface brush, the shortest hairs being on the side of the rod 4.

The longitudinal axis Y of the brush may or may not be aligned with that X of the rod.

The Y axis may form an angle α with the axis X of the rod, as illustrated in FIGS. 32 to 35. The angle α may for example be between approximately 5 ° and 45 °, for example equal to 20 ° approx.

The envelope surface E of the brush may be of circular cross section as illustrated in FIG. 36 or other, in particular polygonal, oblong or with notches or crenellations.

When the twisted core is bent, the bend can be located more or less close to the rod 4, as shown in Figures 32 to 35.

In non-illustrated variants, the soul is curved.

FIG. 37 shows another alternative embodiment of the invention.

FIG. 37 represents a part of the kit according to the invention in which one of the compositions in accordance with the invention is contained in a receptacle 2 in the form of a flexible tube.

Other modes of distribution may be used to deposit said composition on the applicator 3, for example a pump dispenser, without departing from the scope of the present invention.

FIG. 38 represents a kit according to the invention, in the form of a single packaging, comprising a container 2 containing a composition according to the invention and the applicator 3, and a second container 70 containing the second composition according to the invention and a second applicator 71 which may be different from the applicator 3. For example, the applicator 71 may comprise a conventional mascara brush.

In the example illustrated in FIG. 38, the container 2 comprises a lower skirt 72 provided with a thread and constituting a closure cap for the container 70.

The applicator 71 may for example make it possible to apply the first composition to the eyelashes, then the user may use the applicator 3 to make up only a portion of the eyelash fringe, advantageously at most one-third of said fringe, and even more preferably, the outer portion of the eyelash fringe, on at most a third of the fringe.

Other examples of devices comprising two containers and two applicators have been shown in FIGS. 39 to 42.

The applicators are in these examples oriented in opposite directions so that each container can serve as a gripping member to the applicator associated with the other container.

In Figure 39, the device comprises a mascara brush and an applicator 3 according to the invention comprising a comb, while the applicator 3 of the device of Figure 40 comprises a brush.
