Description

• This application claims benefit of U.S. Provisional Application No. 60/796,863, filed May 3, 2006, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. FR 06/51406, filed Apr. 21, 2006, the contents of which are also incorporated herein by reference.
• Disclosed herein is a kit for making up and/or caring for the eyelashes, comprising at least two cosmetic compositions for making up and/or caring for the eyelashes (e.g., mascaras), at least one of the compositions being a charging composition, wherein the kit comprises at least one applicator for applying the at least one charging cosmetic composition to a portion of the eyelash fringe, for example, to the outer third of the eyelash fringe.
• It is desirable to provide novel makeup effects on the eyelashes, for instance, to deposit mascara more substantially on only a portion of the eyelash fringe.
• Using an applicator of standard brush or comb type, it may prove difficult to place a precise deposit of material on only a portion of the eyelashes, while avoiding the formation of lumps.
• It may be useful, in order to obtain certain makeup effects, to apply deposits of contrasted material on unconnected areas of the eyelash fringe.
• The present inventors have found that by applying a larger amount of makeup on part of the eyelashes, for example, on not more than one third of the eyelash fringe, such as the outer part of the eyelash fringe, a certain makeup result can be afforded, which opens the gaze and enlarges the eyes, optically modifying the perception of the shape of the eyes. Such makeup comprising a larger deposit of material on not more than a third of the fringe, for example, on the exterior of the fringe, may give an impression of almond-shaped and elongated eyes, the outer corner of which is raised (“lifting” effect on the gaze).
• Thus, disclosed herein is an eyelash makeup kit which achieves at least one of the objectives described above.
• Disclosed herein is a kit for making up and/or caring for the eyelashes, comprising at least two cosmetic compositions (i) and (ii) for making up and/or caring for the eyelashes, wherein:
• at least one of the compositions (i) and (ii) comprises an oily continuous phase,
• the difference between the dry extract content of composition (ii) and the dry extract content of composition (i) is greater than or equal to 2%, for instance, greater than or equal to 3%, and
• the kit comprises an eyelash fringe applicator comprising:
• a plurality ofapplication members6;60 arranged on asupport5 in the form of at least one row whose length is such that theapplication members6;60 can at most simultaneously contact not more than a quarter of the eyelashes of the fringe.
• Also disclosed herein is a kit for making up and/or caring for the eyelashes, comprising at least two cosmetic compositions (i) and (ii) for making up and/or caring for the eyelashes, wherein:
• at least one of the compositions (i) and (ii) comprises an oily continuous phase,
• composition (i) has a dry extract content of less than or equal to 42% by weight relative to the total weight of the composition,
• composition (ii) has a dry extract content of greater than 42% by weight relative to the total weight of the composition, and
• the kit comprises an eyelash fringe applicator comprising a plurality ofapplication members6;60 arranged along asupport5 in at least one row having a length such that theapplication members6;60 can at most simultaneously contact not more than a quarter of the eyelashes of the fringe.
• The present inventors have observed that the application to the eyelashes of composition (i) and composition (ii), at least one of which is applied using the applicator disclosed herein, can make it possible to produce a more volumizing or charging deposit on part of the eyelash fringe, for example on not more than the outer third of the eyelash fringe. In at least one embodiment, composition (ii) is the composition applied using the applicator disclosed herein.
• Composition (i) can make it possible to obtain a smooth, uniform deposit, which is easy to apply, and which coats, separates and/or lengthens the eyelashes. Composition (i) may make it possible to obtain sparingly charging makeup, i.e. it does not thicken the eyelashes, so as to obtain a natural makeup result. It may thus be possible to easily produce, on this first film of makeup, a more volumizing or charging deposit on only part of the eyelash fringe, for example, on not more than the outer third of the eyelash fringe, by applying composition (ii), which, by virtue of its total wax solids content, may make it possible to obtain a larger deposit of material.
• Thus, the kits disclosed herein may make it possible to accentuate the contrast between the makeup afforded by the deposit of composition (i) and that afforded by the deposit of composition (ii), while at the same time avoiding the formation of “blobs,” which are considered unaesthetic.
• Further disclosed herein is a process for making up and/or for the non-therapeutic care of the eyelashes, comprising:
• applying to the eyelashes at least one coat of a composition (i) as described herein, and applying at least one coat of a composition (ii) as described herein,
• wherein at least one of the compositions (i) and (ii) comprises a continuous oily phase, and
• wherein composition (ii) is applied using an applicator comprising a plurality of application members arranged along asupport5 in at least one row having a length such that theapplication members6;60 can at most simultaneously contact not more than a quarter of the eyelashes of the fringe.
• Still further disclosed herein is a made-up support, such as false eyelashes, comprising a makeup that can be obtained according to the processes defined herein.
• The makeup kits in accordance with the present disclosure comprise at least one physiologically acceptable medium, such as a cosmetically acceptable medium, i.e., a medium that is compatible with the skin and keratin materials, for example, the eyelashes and the area of the eyes.
• The user can obtain the makeup effect according to the present disclosure by contrasted deposit of material via at least two application actions.
• The order of application of composition (i) and of composition (ii) can vary. However, in at least one embodiment, composition (i) is applied before composition (ii).
• Depending on the order of application, one or the other of the cosmetic compositions may be termed a “base coat” or a “top coat”.
• As used herein, the term “cosmetically acceptable” means a compound or composition compatible with the skin and keratin materials, for example, the eyelashes and the area around the eyes.
• As used herein, the term “fringe” denotes the eyelashes of the upper eyelid or those of the lower eyelid, from the inner corner to the outer corner of the eyelid, or the eyebrows of the eyebrow arch of the user's eyes.
• Unless otherwise specified, all the contents of components are expressed herein as solids content.

COMPOSITIONS
• The components that may be comprised in compositions (i) and (ii) are described in more detail below.
• There are, in practice, generally two types of mascara formulations, i.e., mascaras with an aqueous continuous phase, which are known as “emulsion mascaras,” in the form of an emulsion of waxes in water, and mascaras with a solvent or oil continuous phase, which are anhydrous or have a low content of water and/or water-soluble solvents, which are known as “waterproof mascaras,” which may be formulated in the form of a dispersion of waxes in non-aqueous solvents.
• As used herein, the term “composition with an oily continuous phase” means that the composition has a conductivity, measured at 25° C., of less than 23 μS/cm (microSiemens/cm), the conductivity being measured, for example, using an MPC227 conductimeter from Mettler Toledo and an Inlab730 conductivity measuring cell. The measuring cell is immersed in the composition so as to remove the air bubbles that might be formed between the two electrodes of the cell. The conductivity reading is taken once the conductimeter value has stabilized. A mean is determined on at least three successive measurements.
• As used herein, the term “composition with an aqueous continuous phase” means that the composition has a conductivity, measured at 25° C., of greater than or equal to 23 μS/cm (microSiemens/cm), the conductivity being measured, for example, using an MPC227 conductimeter from Mettler Toledo and an Inlab730 conductivity measuring cell. The measuring cell is immersed in the composition so as to remove the air bubbles that might be formed between the two electrodes of the cell. The conductivity reading is taken once the conductimeter value has stabilized. A mean is determined on at least three successive measurements.
• According to one embodiment of the present disclosure, at least one of the two compositions (i) and (ii) comprises an oily continuous phase, wherein the other composition may comprise an aqueous continuous phase or an oily continuous phase.
• According to another embodiment, the two compositions (i) and (ii) comprise an oily continuous phase.
• According to a further embodiment, the present disclosure relates to the kits and processes employing waterproof mascaras.
• Solids Content
• As used herein, the terms “solids content” and “dry extract content” mean the content of non-volatile matter.
• This amount of solids, commonly known as the “dry extract” or as its abbreviated form “DE,” of the compositions according to the present disclosure may be calculated (theoretical DE) or may be measured by heating the sample with infrared rays with a wavelength ranging from 2 μm to 3.5 μm. The substances contained in the compositions that have a high vapour pressure evaporate under the effect of this radiation. Measurement of the weight loss of the sample makes it possible to determine the “dry extract” of the composition. These measurements are taken using an LP 16® commercial infrared desiccator from Mettler. This technique is fully described in the machine documentation supplied by Mettler.
• The measuring protocol is as follows:
• About 1 g of the composition is spread on a metal crucible. After placing it in the desiccator, the crucible is subjected to a nominal temperature of 120° C. for 1 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 the radiation, are measured using a precision balance. The solids content is calculated in the following manner:
  Dry Extract=100×(dry mass/wet mass).
• The values measured using the protocol described above may differ from the corresponding theoretical values by plus or minus 1%.
• The compositions (i) in accordance with the present disclosure can have a dry extract content of less than or equal to 42% by weight, for example, less than or equal to 41% by weight, or less than or equal to 40% by weight relative to the total weight of the composition.
• The compositions (ii) according to the present disclosure may have a dry extract content of greater than 42% by weight, for instance, greater than or equal to 43% by weight relative to the total weight of the composition.
• Oily Phase
• The oily phase of composition (i) and/or (ii) in accordance with the present disclosure can comprise at least one oil and/or at least one organic solvent.

Such waxes are described, for example, in French Patent Application No. 2 792 190.
• According to one embodiment, the compositions (i) and/or (ii) may comprise at least one “tacky” wax, i.e., a wax with a tack of greater than or equal to 0.7 N.s and a hardness of less than or equal to 3.5 MPa.
• The use of a tacky wax may allow for the production of a cosmetic composition that is easy to apply to the eyelashes, that attaches well to the eyelashes and may lead to the formation of a smooth, uniform, and thickening makeup.
• The tacky wax used may have a tack ranging, for example, from 0.7 N.s to 30N.s, such as greater than or equal to 1 N.s, for instance, ranging from 1 N.s to 20 N.s, such as greater than or equal to 2 N.s, for instance, from 2 N.s to 10 N.s, or from 2 N.s to 5N.s.
• The tack of the wax may be determined by measuring the change in force (compression force or stretching force) as a function of time, at 20° C., using the texturometer sold under the name TA-TX2i® by the company Rheo, equipped with a conical acrylic polymer spindle forming an angle of 45°.
• The measuring protocol is as follows:
• The wax is melted at a temperature equal to the melting point of the wax +10° C. The molten 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 such that the surface of the wax is flat and smooth, and the wax is then stored for at least 1 hour at 20° C. before measuring the tack.
• The texturometer spindle is displaced at a speed of 0.5 mm/s then penetrates the wax to a penetration depth of 2 mm. When the spindle has penetrated the wax to a depth of 2 mm, the spindle is held still for 1 second (corresponding to the relaxation time) and is then withdrawn at a speed of 0.5 mm/s.
• During the relaxation time, the force (compression force) decreases greatly until it becomes zero, and then, during the withdrawal of the spindle, the force (stretching force) becomes negative and then rises again to the value 0. The tack corresponds to the integral of the curve of the force as a function of time for the part of the curve corresponding to negative values of the force (stretching force). The tack value is expressed in N.s.
• The tacky wax that may be used may have a hardness of less than or equal to 3.5 MPa, for example, ranging from 0.01 MPa to 3.5 MPa, such as from 0.05 MPa to 3 MPa, or from 0.1 MPa to 2.5 MPa.
• The hardness is measured according to the protocol described previously.
• Non-limiting examples of a suitable tacky waxes include C₂₀-C₄₀alkyl (hydroxystearyloxy)stearates (wherein the alkyl group comprises from 20 to 40 carbon atoms) and mixtures thereof, such as C₂₀-C₄₀alkyl12-(12′-hydroxystearyloxy)stearates, of formula (II):

  

  
  wherein m is an integer ranging from 18 to 38, and mixtures thereof.
• A non-limiting example of such a wax is sold under the names Kester Wax K 82 P® and Kester Wax K 80 P® by the company Koster Keunen.
• The waxes mentioned above may have a starting melting point of less than 45° C.
• A further non-limiting example of a suitable wax is the microcrystalline wax sold under the reference SP18 by the company Strahl & Pitsch, which has a hardness of about 0.46 MPa and a tack value of about 1 N.s.
• The at least one wax may be in the form of an aqueous microdispersion of wax. As used herein, the expression “aqueous microdispersion of wax” means an aqueous dispersion of wax particles in which the size of the wax particles is less than or equal to about 1 μm.
• Wax microdispersions are stable dispersions of colloidal wax particles, and are described, for example, in “Microemulsions Theory and Practice,” L.M. Prince Ed., Academic Press (1977) pages 21-32.
• These wax microdispersions may be obtained by melting the wax in the presence of a surfactant, and optionally a portion of water, followed by gradual addition of hot water with stirring. The intermediate formation of an emulsion of the water-in-oil type is observed, followed by a phase inversion, with final production of a microemulsion of the oil-in-water type. On cooling, a stable microdispersion of solid wax colloidal particles is obtained.
• The wax microdispersions may also be obtained by stirring the mixture of wax, surfactant, and water using stirring means such as ultrasound, high-pressure homogenizers, and turbomixers.
• For instance, the particles of the wax microdispersion can have mean sizes of less than 1 μm (for example, ranging from 0.02 μm to 0.99 μm), for instance, less than 0.5 μm (for example, ranging from 0.06 μm to 0.5 μm).
• In at least one embodiment, these particles may comprise at least one wax. In at least one other embodiment, they may comprise a small proportion of oily and/or pasty fatty additives, a surfactant, and/or a common liposoluble additive/active agent.

• According to another embodiment, composition (ii) may have a wax content of greater than or equal to 20% by weight, for example, greater than or equal to 25% by weight, or greater than or equal to 27% by weight, which may be up to 50% by weight, relative to the total weight of composition (ii).
• Also disclosed herein is a kit for making up and/or caring for the eyelashes, comprising at least two cosmetic compositions (i) and (ii) for making up and/or caring for the eyelashes, wherein:

• In another embodiment, the two compositions (i) and (ii) may also differ in at least one optical characteristic that is visible to the naked eye, other than the shade afforded by the presence of dyestuffs, for example, the sheen.
• Kits
• The kit according to the present disclosure may comprise at least one applicator for applying the cosmetic compositions (i) and/or (ii) in accordance with the disclosure.
• In at least one embodiment, composition (ii) may be applied using an applicator described in more detail below.
• In another embodiment, composition (i) may be applied using any brush and/or comb commonly used for making up the eyelashes and/or the eyebrows.
• In yet another embodiment, composition (i) may be applied with a makeup brush as described in French Patent Nos. 2 701 198 and 2 605 505 and European Patent Nos. 0 792 603 and 0 663 161.
• The makeup kit according to the present disclosure may, according to one embodiment, comprise at least two separate packagings, one comprising composition (i) as defined herein and the other comprising composition (ii) also as defined herein, either one possibly being, without preference, a “top coat” or “base coat” composition depending on the order of application, as has been described herein.
• The kit according to the present disclosure may further comprise at least one wiping member. This wiping member may comprise, for example, a block of an alveolar material such as an open-cell or closed-cell foam, with or without flocking. In another embodiment, the at least one wiping member may comprise an optionally flocked, non-alveolar material, chosen from, for example, elastomers and polyolefins. In this embodiment, the at least one wiping member may comprise, for example, at least one slit and/or may comprise a lip arranged to wipe the stem.
• Since the application of makeup to the eyelashes or the eyebrows is performed by means of a multiple action by the user, i.e. in at least two steps, the first comprising applying the “base coat” composition and the second comprising applying the “top coat” composition totally or partially over the base coat, a makeup kit contained in one and the same packaging may be used.
• When the kit is in the form of one packaging, it may be presented as a container delimiting at least one compartment or reservoir that comprises composition (i), the said compartment being optionally closed by means of a closing member, and at least one compartment or reservoir that comprises composition (ii), also being optionally closed by means of a closing member.
• Again, when the kit is in the form of one packaging, this packaging may comprise at least one applicator for the composition (i), for example, a brush comprising an arrangement of bristles maintained by a twisted wire. Such a twisted brush is described, for example, in U.S. Pat. No. 4,887,622, which is incorporated herein by reference in its entirety. The applicator may also be in the form of a comb comprising a plurality of application members, obtained, for instance, by molding. Such combs are described, for example, in French Patent No. 2 796 529, which is incorporated herein by reference in its entirety. In one embodiment, the applicator may be solidly attached to the container, as described, for example, in French Patent No. 2 761 959, which is incorporated herein by reference in its entirety. In another embodiment, the applicator may be solidly attached to a stem, which is itself solidly attached to a closing member.
• The closing member may be coupled to the container by screwing. Alternatively, the coupling between the closing member and the container takes place other than by screwing, for example, via a bayonet mechanism, by click-fastening, or by tightening. As used herein, the term “click-fastening” means any system involving the passing of a rim or bead of material by elastic deformation of a portion, such as, of the closing member, followed by return to the elastically unstressed position of the said portion after the rim or bead has been passed.
• The container, which may comprise two compartments or reservoirs, may be at least partly made of thermoplastic material. Examples of thermoplastic materials include, but are not limited to, polypropylene and polyethylene.
• In another embodiment, the container may be made of a non-thermoplastic material, for example, glasses and metals (or alloys).
• The container may further comprise a drainer located in the region of at least one aperture of the container. Such a drainer may make it possible to wipe the applicator and, optionally, the stem to which it may be solidly attached. Such a drainer is described, for example, in French Patent No. 2 792 618, which is incorporated herein by reference in its entirety.
• According to one embodiment, the makeup kit comprises two reservoirs each comprising one composition chosen from the “base coat” and “top coat” compositions, one of the reservoirs being equipped with a makeup brush, such as a mascara brush as described above, and the other reservoir being equipped with an applicator described in more detail below.
• Applicator
• The applicator included in the kit according to the present disclosure comprises a plurality ofapplication members6;60 arranged along asupport5 in at least one row having a length such that theapplication members6;60 can at most simultaneously contact not more than a quarter of the eyelashes of the fringe.
• According to one embodiment, the applicator included in the kit according to the present disclosure comprises:
• astem4, wherein thesupport5;61 is associated with thestem4 and extends along a longitudinal axis, wherein theapplication members6;60, and in at least one embodiment, two application members, extend substantially transversely to the longitudinal axis of the support.
• Thus, according to one embodiment, the applicator comprises a plurality ofapplication members6;60 arranged along asupport5 in at least one row having a length such that theapplication members6;60 can at most simultaneously contact not more than a quarter of the eyelashes of the fringe.
• The application members can extend over a distance along the longitudinal axis of the support such that the application members can at most simultaneously contact not more than a quarter, for example, not more than a fifth, or not more than a sixth, of the eyelashes or of the eyebrows of the fringe when the longitudinal axis of the support is oriented substantially tangentially to the fringe.
• A portion of made-up eyelashes or eyebrows may, for example, correspond to not more than a quarter, for instance, not more than a fifth, or not more than a sixth of the length of the fringe.
• In at least one embodiment, the application members may comprise teeth and/or bristles.
• This applicator may make it possible to conveniently charge the eyelashes while at the same time exerting a possible combing action.
• The application members may extend along the support over a distance that is short enough to be able to make up at least one lock of eyelashes, which may make it possible to obtain novel makeup effects.
• This applicator may make it possible to deposit in a supported manner material on at most a third, for example, at most a quarter of the eyelash fringe to be made up, for instance, the exterior of the eyelash fringe.
• The application members may extend, for example, along the support over a distance ranging from 0.1 to 1 cm, for example, less than or equal to 8 mm, less than or equal to 7 mm, or less than or equal to 6 mm, for example, a distance ranging from 2 mm to 5 mm, such as from 2 mm to 3 mm.
• The applicator included in the kit according to the present disclosure may comprise astem4, wherein thesupport5;61 is associated with thestem4 and extends along a longitudinal axis, wherein there is at least one row of application members comprising teeth, arranged along the support, and wherein the application members of the row each extending substantially transversely to the longitudinal axis of the support and wherein a distance from the free ends to a longitudinal axis varies non-monotonously between end application members of the row.
• As used herein, the term “varying non-monotonously” means that the line connecting the free ends of the application members has a distance to the longitudinal axis of the support that passes through at least one extremum, for example a maximum.
• The presence of a maximum in the at least one row of application members may allow gradual penetration of the application members into the eyelashes and thus may facilitate the makeup of a portion of eyelash fringe according to the present disclosure.
• The number of application members of the row, for instance, the number of teeth, may range, for example, from 3 to 9, from 3 to 8, or from 3 to 7.
• According to one embodiment, the support and the application members may be made as a single piece, for example, by molding or machining. In another embodiment, the application members may be associated with the support.
• The support and the stem may be made as a single piece, for example, by molding, or, in another embodiment, the support may be associated with the stem. In this embodiment, the support may comprise a tip arranged so as to engage in housing for the stem, or the stem may comprise a tip arranged so as to engage in housing for the support.
• The stem may extend along a longitudinal axis different from the longitudinal axis of the support. In this case, the longitudinal axis of the stem may form with the longitudinal axis of the support, for instance, the portion thereof that the application members extend substantially transversely to, an angle ranging from 5° to 45°, for example, from 15° to 25°, such as 20°. This configuration may allow more comfortable handling of the applicator during the application of a makeup composition in accordance with the present disclosure to the eyelashes. The longitudinal axis of the support may be, for example, curvilinear or rectilinear.
• In one embodiment, the stem may extend along a longitudinal axis that is identical to the longitudinal axis of the support.
• The applicator and/or the support may be at least partially made of a supple or rigid material, chosen from, for example, thermoplastic, elastomeric, and elastomeric-thermoplastic materials, and made for instance, by moulding. In another embodiment, the applicator may be at least partially made of materials chosen from wood, metal, and other materials, for instance, by machining.
• When the support is made of an elastically deformable material, this may make it possible to perform wiping of one side of the support.
• The stem and the support may or may not be made of different materials.
• When the applicator is observed from the side, the line connecting the free ends of the application members may have a distance to the longitudinal axis of the support that passes through at least one extremum, for instance, a maximum, which may make the penetration of the applicator into the eyelashes more gradual.
• The abovementioned line may have at least partially a pointed shape, for example, triangular, or a rounded shape, such as circular or ogival.
• Irrespective of the profile of the abovementioned line, when there is a maximum and a minimum, the angle formed between the straight line connecting the free ends of an application member of the greatest length associated with this maximum and of an application member of smallest length associated with the closest minimum of the application member of the longest length, and the normal to the longitudinal axis of the support, this normal passing through the free ends of the application member of greatest length, may range, for example, from 25° to 60°, from 25° to 50°, from 25° to 45°, or from 30° to 45°, for example, equal to 43°.
• The distance from the abovementioned line to the longitudinal axis of the support may also pass through two or more extremes.
• The application members may be arranged in a single row or in at least two rows. In the latter case, the application members of a first row and those of a second row may extend in different directions or, in another embodiment, in parallel directions. The two rows may be, for example, arranged substantially opposite each other relative to the support.
• The height of the application members may range, for example, from 0.5 to 10 mm, for example, from 1 to 3 mm.
• When these application members are arranged in at least one row, this row may comprise a succession of application members extending alternately, at least partially, along either side of a geometrical separating surface.
• The application members may or may not have aligned bases.
• When the application members are arranged in at least one row, the row may extend along a non-rectilinear axis. The application members may also be arranged alternately on either side of a median core.
• Again when the application members are arranged in at least one row, this row may comprise a succession of application members located alternately, at least partially, on either side of a geometrical separating surface, two consecutive application members having adjacent parts that are connected or that overlap when the applicator is observed from the side, and forming between them a groove for receiving an eyelash.
• The applicator may comprise a comb or a brush.
• When the applicator comprises a brush, the support may comprise two twisted wires of small diameter, for instance, less than 0.7 mm, for example, ranging from 0.2 to 0.6 mm, or from 0.35 to 0.5 mm.
• When the applicator comprises a brush, the application members may be bristles of small diameter, for example less than or equal to 8/100 mm, such as less than or equal to 6/100 mm.
• When the brush comprises a twisted core, the number of spires of the brush may range, for example, from 3 to 6. In the case of a brush with a twisted core, the bristles may extend from the core in two helical courses. The number of spires of the brush corresponds to the sum of the revolutions around the core of the two courses. Part of the twisted core may be free of bristles, for example, close to the association between the support and the stem.
• The cross section of the envelope surface of the brush may chosen from circular, square, and other shapes.
• In another embodiment, the brush may have a biconical envelope surface. The envelope surface may also be conical or frustoconical with the base of the cone located on the side of the distal or proximal end of the brush.
• The applicator included in the kit according to the present disclosure may take the form of a brush for the application of a product to the eyelashes, comprising a twisted core and bristles extending from the core, the number of spires being less than or equal to 6.
• The applicator included in the kit according to the invention may also take the form of a brush for the application of a product to the eyelashes, comprising a core and bristles extending from the core, the length of the portion of the brush bearing the bristles being less than or equal to 8 mm, for example, less than or equal to 7 mm, or less than or equal to 6 mm.
• The applicator included in the kit according to the present disclosure may also take the form of a core and bristles extending from the core, contained in an envelope surface of substantially frustoconical, conical, or biconical shape, in which the smallest angle formed between a plane containing the largest cross section of the brush and a tangent to the envelope surface of the brush at the intersection with this plane ranges from 20° to 60°, for example, from 25° to 50°, such as from 30° to 35°.
• The applicator included in the kit according to the present disclosure may also take the form of a composition in accordance with the present disclosure for the eyelashes, comprising a core and bristles extending from the core, in which the envelope surface of the brush has a substantially biconical shape, with an apex angle at the junction of the cone frustums of less than or equal to 120°, for example, less than or equal to 90°.
• The applicator included in the kit according to the present disclosure may also take the form of a comb for the application of a product to the eyelashes, comprising a support and teeth extending transversely to the longitudinal axis of the support, the distance between the extreme teeth along the longitudinal axis being less than or equal to 8 mm, for example, less than or equal to 7 mm, or less than or equal to 6 mm.
• The applicator included in the kit according to the present disclosure may also take the form of a comb for the application of a product to the eyelashes, comprising a support and teeth extending transversely to the longitudinal axis of the support, comprising a tooth of greatest length having a first length and a tooth of shortest length having a second length, wherein the ratio of the first length to the second length is greater than or equal to 1.3.
• The applicator included in the kit according to the present disclosure may also take the form of a comb for the application of a product to the eyelashes, comprising a support and teeth extending transversely to the longitudinal axis of the support, in which the angle formed between a straight line joining the free end of a tooth of shortest length and the free end of a tooth of longest length and the line perpendicular to the longitudinal axis of the support passing through the free end of the tooth of longest length ranges from 20° to 600°.
• When the kit comprises a wiping member, the applicator support may be profiled so as to facilitate passage into the wiping member and may comprise for this purpose, for example, a rounded nose at the front and a bump at the back.
• The applicator stem may be associated with a cap for closing the container, which may also serve as a handling member, and the applicator may be housed inside the container when it is in the closed position.
• Certain embodiments of the present disclosure will now be discussed in more detail in the context of the figures provided and described herein. These figures are not intended to limit in any way to the scope of the present disclosure. Moreover, the characteristics of the various embodiments depicted in the figures may be combined.
• As shown The device1, shown inFIG. 1, corresponds to a part of the kit when this kit is contained in two separate packagings. Device1 comprises acontainer2 containing a reserve of a cosmetic product P, in the present case a composition chosen from compositions (i) and (ii), and anapplicator3 comprising astem4 of longitudinal axis X. This device comprises an applicator in accordance with one embodiment of the present disclosure and contains only one of the compositions in accordance with the present disclosure.
• Thestem4 is fitted at one end with asupport5 comprising a plurality ofapplication members6 and thestem4 is associated at the opposite end to acap7 for closing thecontainer2, which also constitutes a handling member.
• Theclosing cap7 may comprise inner threading, not shown, for screwing onto the externally threadedneck11 of thecontainer2.
• Thecontainer2 comprises, in the example described, a wipingmember8 engaged in theneck11 and comprising a wipinglip9 arranged so as to wipe thestem4 and thesupport5 equipped with theapplication members6.
• The wipingmember8 can, where appropriate, be arranged such that it can become deformed on passage of theapplication members6.
• The wipingmember8 may be made by injection moulding, for example of a polyolefin.
• Thecontainer2 is hermetically closed when not in use, by screwing theclosing cap7 onto theneck11.
• In the example shown, theapplicator3 comprises a comb, theapplication members6 comprising teeth. Thesupport5 extends along a longitudinal axis Y forming with the longitudinal axis X of the stem4 a non-zero angle α, as illustrated inFIG. 3. This angle α may range, for example, from 5° to 45°.
• Theapplication members6, which are six in number in the embodiment depicted inFIG. 1, are arranged in arow10.
• Theapplication members6 may be positioned along thesupport5 in various configurations.
• In the example illustrated inFIG. 3, therow10 comprises a first series ofteeth6aand a second series ofteeth6b, which are respectively located on either side of a geometrical separating surface, which in this embodiment is a midplane of symmetry of the comb, parallel to the plane ofFIG. 3, and may also comprise a joint plane for the moulding of the comb.
• In the embodiment illustrated, theteeth6aand6bare produced alternately on either side of acommon core15 of thesupport5, which serves as a backbone along which the teeth are arranged.
• Thesupport5 is provided at the front with arounded nose17, for facilitating its return into thecontainer2.
• Thesupport5 comprises, at the rear, abump18 for facilitating the crossing of the wipingmember8 during its removal from thecontainer2.
• Theapplication members6 each comprise atop part20 ending with afree end30 and thebottom part22 associated with thecore15 of thesupport5.
• In the embodiment depicted, theapplication members6 extend substantially perpendicularly to the axis Y of thesupport5.
• The free ends30 of the application members are at a distance from the longitudinal axis of the support that varies non-monotonously between end application members of therow10, i.e., from left to right inFIG. 3.
• In the embodiment illustrated, the line L connecting the free ends30 has, when the applicator is observed from the side, in a direction perpendicular to the longitudinal axis of thestem4 and to the abovementioned geometrical separating surface, as illustrated inFIG. 3, a substantially triangular shape, with two rectilinear segments forming between them an angle substantially equal to 90° in the drawing.
• In the embodiment depicted, the succession ofapplication members6 comprises twolarger teeth6aand6bof the same length.
• The straight line D₁passing through the free end of the shortest member starting from the distal end of the applicator and through the free end of the longest member that is closest to this longest member is identical in the embodiment depicted to the first rectilinear segment of the line L.
• The angle γ₁formed between the straight line D, and the perpendicular N₁to the axis Y passing through the free end of the abovementioned longest application member may range, for example, from 25° to 60°, for example, equal to 43°.
• The straight line D₂passing through the shortest application member from the proximal end of thesupport5 and the longest application member that is closest to this member is identical to the second rectilinear segment of the line L.
• The angle γ₂formed between the straight line D₂and the perpendicular N₂to the axis Y passing through the free end of this longest application member may fall in the same range of values as the angle γ₁, for example, γ₂may be substantially equal to γ₁. The apex angle between the segments of the line L may be, for example, less than or equal to 120°, for instance, less than or equal to 90°.
• Theapplication members6 extend on thesupport5 over a relatively short distance, for instance, a distance ranging from 0.1 to 1 cm. Thus, as illustrated inFIG. 2, it is possible, using theapplicator3, to make up only a portion of the eyelash fringe at a time without touching all of the eyelashes of the eyelid. For example, the application members can simultaneously contact, at most, less than a quarter of the eyelashes of the upper eyelid, as illustrated.
• Thesupport5 and theapplication members6 may be made as a single piece, such as in the embodiment illustrated inFIG. 3, by moulding plastic. Thesupport5 is associated with thestem4 in a manner that will be discussed in more detail below, with regard toFIGS. 10 and 11.
• In the embodiment depicted, thetop parts20 of twoconsecutive application members6 form between them agroove21 extending substantially down to thecore15, when the comb is observed from the side, as inFIG. 3. Thegrooves21 may allow the eyelashes to be captured more easily, for example so as to separate them, comb them, or spread out product deposited on their surface.
• By varying the length and interval of the application members, it is possible to modify the amount of product that the applicator takes up.
• As shown inFIG. 3, the gap between the peaks of twosuccessive application members6aor6blocated on the same side of the geometrical separating surface is markedly larger than the width of an application member, measured at approximately mid-height of theapplicator3, parallel to the axis Y of thesupport5.
• Eachapplication member6aextends substantially at mid-distance, when theapplicator3 is observed from the side, from twoadjacent application members6b, and vice versa.
• As shown inFIG. 3, thetop parts20 of theapplication members6 all point in substantially the same direction.
• Thebottom parts22 of two successive application members located on the same side of the core15 form between them and with the core15 acavity23 that can constitute a product reserve.
• The spacing between theapplication members6aor6bmay be relatively large to improve the amount of product that the applicator takes up, without, however, the applicator losing any capacity to grip the eyelashes, by virtue of the staggering of the application members and by the fact that thegrooves21 formed by thetop parts20 of the application members remain sufficiently straight.
• Theapplication members6 may have many configurations without departing from the context of the present disclosure, for instance, differently oriented top parts.
• In accordance with other embodiment of the present disclosure, theapplication members6 may be arranged differently on thesupport5 than the orientation depicted inFIG. 3.
• FIGS. 5 and 6 show another example of an applicator comprising a plurality ofteeth6, for example seven teeth, extending in arow10. Theteeth6, as may be seen inFIG. 6, may have alignedbases22, whereas thetop parts20 of twoconsecutive teeth6aand6bmay diverge.
• FIG. 7 illustrates the possibility of producing thestem4 with a longitudinal axis X that is identical to that Y of thesupport5.
• InFIG. 8, thesupport5 is shown with a longitudinal axis Y forming a non-zero angle α with the longitudinal axis X of thestem4, the sense of the incline of the support inFIG. 8 being opposite that of the support in FIGS.1 to4.
• Thesupport5 may be made as a single piece with thestem4, for example, by moulding plastic as illustrated inFIG. 9. However, thesupport5 may also be associated with thestem4.
• In the embodiment shown inFIG. 10, thesupport5 comprises a substantiallycylindrical tip35 comprising anannular channel36. Thestem4 comprises acorresponding housing37, fitted with anannular rim38 arranged so as to click into thechannel36.
• Thetip35 may also be configured so as to be force-fitted into thestem4.
• In the embodiment depicted inFIG. 11, thestem4 comprises a substantiallycylindrical tip40, arranged so as to house in acorresponding housing41 of thesupport5.
• Theapplicator3 may comprise a number of teeth, for example, less than six or less than seven, and in at least one embodiment, may comprise only twoteeth6 as illustrated inFIG. 12. The teeth may or may not have the same width.
• The line connecting the free ends30 of theapplication members6 may have various shapes other than that of FIGS.1 to11, as illustrated in FIGS.13 to17. For example, the line may have a rounded shape, for example, a substantially circular shape as illustrated inFIG. 13, or an ogival shape as illustrated inFIG. 14. The extremum may be located substantially in the middle of thesupport5 as illustrated previously, may be closer to thestem4 as illustrated inFIG. 15, or may be closer to the distal end of the applicator as illustrated inFIG. 16. In another embodiment, the distance from the line to the longitudinal axis Y of thesupport5 may pass through two extrema as illustrated inFIG. 17.
• FIG. 13 depicts an embodiment in which the support may be without therounded nose17 and/or thebump18.
• FIG. 13 also shows the straight lines D₁and D₂and the normal N to the longitudinal axis Y of thesupport5 that passes through the free end of the longest application member.
• The angles γ₁formed between the straight line D₁and the normal N and γ₂formed between the straight line D₂and the normal N may be identical or different, for example being within the range of values described above in the context ofFIG. 3.
• In the embodiment illustrated inFIG. 17, angles γ₁and γ₂relative to the normal N passing through the free end of the application member associated with the first relative extremum and γ′₁and γ′₂relative to the normal N′ passing through the free end of the application member corresponding to the second relative extremum may be defined, these angles also being, for example, within the range of values given above.
• FIG. 18 illustrates the possibility of arranging along thesupport5 two rows of application members, for example two rows arranged opposite each other relative to thecore15 of thesupport5. The application members may extend differently from one row to the other and, as illustrated inFIG. 18, may have different profiles when theapplicator3 is observed from the side.
