Description

The present invention relates to applicators intended for applying a product to the eyelashes and / or the eyebrows, in particular a cosmetic, makeup or care product, for example mascara. The invention is also concerned with a makeup process.

BACKGROUND For making a more or less loaded make-up it is known to use devices having a container provided with a user-adjustable wringing member. If such devices are satisfactory in their operation. the presence of a wiper member complicates the manufacture and increases the cost.

Application members having different tooth densities on two opposite sides of the core have also been proposed. This makes it quite easy to make two different makeups but more difficult intermediate makeup. Moreover, when the applicator member is used after extraction of the container, the user often uses only a small amount of the product present on the applicator member before returning it to the container. If you bring too much product it becomes difficult to separate the eyelashes. EP 1 632 149 discloses a molded application member having teeth arranged in single rows, at least two rows of single teeth having different spacings. The teeth extend tangentially relative to the surface of the core or in the extension of the face adjacent to the face of which they are connected. International application WO 2009/053925 discloses an applicator comprising a molded application member comprising rows of small teeth and rows of large teeth arranged alternately around the longitudinal axis of the applicator.

In Application EP 2 198 743 there is disclosed an applicator comprising two different application faces and means for locating on the gripping member, the applicator member having a predefined angular position relative to the locating means, so that that the positioning of the applicator given by the marking means corresponds to the use of a predefined application face.

There is a need for a means to produce more or less loaded makeup, while having separate eyelashes. in a progressive and reproducible manner from one time to the other, in particular from an applicator pelmettant easily make such makeup. Method According to one of its aspects, the subject of the present invention is a process for making up the eyelashes or eyebrows by means of an applicator comprising a gripping member and an applicator member, preferably a molded application member. , in which process is rotated on itself at least once, better at least twice, even better at least three times, the applicator member about the longitudinal axis of the core relative to the fringe eyelashes, during use between two successive applications of product, without reloading the application member into product. The method may be implemented by means of an applicator member comprising: - a core having a longitudinal axis, and - teeth extending from the core, the teeth being arranged in rows extending according to the longitudinal axis of the core, for example at least five rows, and the rows being distributed around the core, the rows having first rows and second rows. the first rows differing from the second rows by at least one of the spacing of the teeth in the row, the number of teeth in the row, the implantation of the teeth in the row, the thickness of the teeth, the shape of the teeth , the shape of the cross section of the teeth. The first rows and the second rows may differ in that the teeth of the first rows are separated from each other with a first spacing e1 and the teeth of the second rows are spaced from each other with a second spacing e ', the second gauge e2 being different from the first gap el. at least one first row, or even several first rows, alternating with at least one second row. even several second rows, when one moves around the longitudinal axis of the soul. The method may also be implemented by means of an applicator for applying a product to the eyelashes and / or the eyebrows, comprising an applicator member. especially not molded. for example a twisted brush, comprising: a core having a longitudinal axis, in particular a core formed of a U-folded twisted wire, and bristles extending from the core, comprising first bristles and second bristles different from each other, differing for example from each other by their length and / or the shape of their free end and / or their diameter. In successive applications, the application member can load and then separate. The user can perform sufficient rotations of the applicator member to make it perform a complete revolution without having to reload the applicator member product. It can also, after a complete turn, reload the application member product and then start makeup according to the method above. The applicator member may be rotated relative to the longitudinal axis of the core by rotating the gripping member on its axis. The rotation of the applicator can be total or partial; it is total when the entire applicator rotates at the same time. The applicator member may be rotated on itself without detaching the fingers from the gripping member, or by detaching a finger and retaining another finger in contact with the gripping member, or by peeling off all the fingers of the grasping organ. The rotation is preferably performed manually. The applicator can thus not be motorized. The applicator member may be free to rotate relative to a support attached to the gripping member. In this case, the rotation of the applicator member with respect to the axis may result from the resistance exerted by the eyelashes on the applicator member during the application. When the user brings the applicator member into contact with the eyelashes for a second application, the area of the applicator member which comes into contact with the eyelashes is no longer the same as during the first application. . Alternatively, the applicator member may be rotated relative to the longitudinal axis of the core by rotating a rotatable portion of the gripping member relative to a fixed portion of the gripping member. The process may advantageously be carried out with an applicator as defined below.

Applicator The subject of the present invention is also, according to one of its aspects, an applicator for applying a product to the eyelashes and / or the eyebrows, comprising a molded application member comprising: a core having a longitudinal axis, and teeth extending from the core, the teeth being arranged in at least five rows extending along the longitudinal axis of the core and the rows being distributed all around the core, the at least five rows having first rows and second rows, the first rows differing from the second rows by at least one of the spacing of the teeth in the row, the number of teeth in the row, the location of the teeth in the row, the thickness of the teeth, the shape of the teeth, the shape of the cross section of the teeth, several first rows alternating with at least a second row 15 as one moves around the longitudinal axis of the soul , the average length e teeth of a row being substantially constant from one row to another. The applicator according to the invention makes it possible to make up the eyelashes and / or eyebrows by very easily alternating the charging and separating phases as a function of the rows used. The makeup obtained is surprisingly natural and lengthening. The user can slightly turn the application member during makeup, to proceed with successive touches and get a well-loaded makeup and well separated. The user does not have to locate the positioning of his fingers on the gripping member; it is sufficient to turn the latter slightly on itself so that a new zone of the applicator member 25 becomes operative, to load the eyelashes or to separate them. The invention makes it possible to provide layers of successive products without the latter having time to dry, contrary to what may be the case if the applicator member is loaded into a container between the application of two layers, thus applying the product in small successive loads, which allows to gradually load the eyelashes without sticking them.The eyelashes can be made by recharging the eyelashes before the product of the previous layer is dried This makes it possible to separate the latter well and to prevent them from sticking together, thus obtaining a make-up which can be made gradually and modulated at will, The makeup obtained advantageously makes it possible to separate the eyelashes particularly well.

The invention further relates, in another of its aspects, to an applicator for applying a product to the eyelashes and / or the eyebrows, comprising a molded application member comprising: a core having an axis longitudinal, and - teeth extending from the core, the teeth being arranged in at least five rows extending along the longitudinal axis of the soul and the rows being distributed around the soul, the at least five rows having first rows and second rows, the teeth of the first rows being spaced from each other with a first spacing and and the teeth of the second rows being spaced apart from each other with a second spacing e2, the second spacing e2 being greater than or equal to 1.5 times the first gap e7, a plurality of first rows alternating with at least a second row when moving around the longitudinal axis of the core. Another subject of the invention, according to another of its aspects, is an applicator for applying a product to the eyelashes and / or the eyebrows, comprising a molded application member comprising: a core having a longitudinal axis, and teeth extending from the core, the teeth being disposed in at least five rows extending along the longitudinal axis of the core and the rows being distributed all around the core, the at least five rows comprising first rows and second rows, the teeth of the first rows being spaced from each other with a first spacing ej and the teeth of the second rows being spaced apart from each other with a second spacing e2, the second spacing e2 being greater or equal to 1.5 times the first 30. spacing el, at least a first row alternating with at least a second row when moving around the longitudinal axis of the soul, the rows do not extend not in the extension of one side of the soul or tangentially to the soul. The invention further relates, in another of its aspects, to an applicator for applying a product to the eyelashes and / or the eyebrows, comprising a molded application member comprising: a core having an axis longitudinal, and teeth extending from the core, the teeth being arranged in at least five rows extending along the longitudinal axis of the soul and the rows being distributed around the soul, 10 at least five rows having first rows and second rows, the first rows differing from the second rows by at least one of the spacing of the teeth in the row, the number of teeth in the row, the location of the teeth in the row, the thickness of the teeth, the shape of the teeth, the shape of the cross section of the teeth, several first rows alternating with at least a second row when moving around the longitudinal axis of the soul , the application member being connected by a rod to a gripping member, the gripping member having locating means for positioning the applicator with respect to the user. The teeth of the first rows may be spaced from each other with a first gap and the teeth of the second rows may be spaced apart from each other with a second gap e2, the second gap e being different from the first gap el. Rows whose teeth are further apart may be particularly useful for loading the product with eyelashes. Rows whose teeth. are closer together can allow to particularly promote the separation of the eyelashes between them. By "longitudinal axis of the soul" is meant the line joining all the centroids of the cross sections of the soul. The longitudinal axis may be a central axis, or even an axis of symmetry for the core, especially when the core has a circular cross section or in the general shape of a regular polygon. The longitudinal axis of the core may be rectilinear or curved and may be contained in a plane. which can be a plane of symmetry for some. even all the cross sections of the soul. By "tooth" is meant an individualizable projecting element intended to come into engagement with the eyelashes. this term being synonymous with "hair" in the context of the present invention. By "spacing" of the teeth in a row, is meant the distance between the axes of elongation of two consecutive teeth of a row, when moving along the longitudinal axis of the soul. In the case of straight and parallel teeth, the spacing is measured between the vertices.

By "row of teeth" is meant a set of teeth arranged along an axis of the row. The set of teeth forming the row can go from one end to the other of the applicator member. from one end to the other of a portion of the core bearing all the teeth of the applicator member, or in a more restricted manner on only a portion of a length of the core measured according to its longitudinal axis, for example between 1/4 and 3/4 of the length of the soul. The "row" may comprise at least five teeth, better still at least eight teeth, even better at least ten teeth, more preferably at least 15 teeth, arranged along the axis of the row. By "simple row" is meant a row of teeth in which the teeth are aligned along an axis of the row, which may be parallel or substantially parallel to the longitudinal axis of the core. By "multiple row". means a row of teeth composed of teeth circumferentially offset relative to each other as one moves along the longitudinal axis of the soul, while succeeding one another as one moves along the longitudinal axis of the soul. The multiple row can be considered as a single row or as several single rows arranged side by side. The multiple row can be a double row. a triple row. or a quadruple row for example. By "double row" is meant a row of teeth composed of teeth arranged on either side of a geometric separation surface, the teeth succeeding each other when one moves along an axis of the parallel row. to the longitudinal axis of the soul. It is possible to consider that the teeth of the double row form two rows of single teeth, each row of single teeth extending along a longitudinal axis of the single row is each extending on one side of the geometric surface of the separation of the double row. By "row not extending in the extension of one side" it should be understood that the teeth of the row do not extend all parallel and in the continuity of said side. when the soul is of polygonal cross section. By "row not extending tangentially to the soul" it should be understood that the teeth of this row do not all extend tangentially to the soul when the latter is not polygonal. By "row of teeth V" is meant two single rows of teeth parallel to each other, the teeth of one row having the same axial position as the teeth of the other row along the axis longitudinal support, and forming a notch between them. By "implantation of the teeth in the row" means the arrangement of the teeth of the row on the core, with respect to the longitudinal axis of the core, that is to say the spacing between the teeth, the axial position of the teeth in the row, the circumferential position of the teeth in the row. Examples of implantation are for example a single row, multiple row, V, staggered layout. According to the examples. the soul may carry an even or odd number of rows, for example at least five. at least six, at least seven, at least eight. at least nine or at least ten rows of teeth, or even eleven or twelve. Preferably, the applicator may comprise an even number of rows. The applicator may comprise at least five alternations between the first and second rows, or even at least six, or even seven, or even eight, or even nine, ten, even eleven, even twelve alternations.

"Alternation" means the passage from one or more first row (s) to one or more second row (s) or vice versa. By "alternating" is meant passing as one moves about the longitudinal axis of the soul, at least once from a first to a second row, and then at least once from a second to a first row, and finally again at least once from a first to a second row.

Such alternation can be regular, the applicator having a repetition of the same pattern formed by first (s) and second) rows, when moving around the longitudinal axis of the soul. The applicator according to the invention may in particular be devoid of more than two first consecutive rows, for example of first three consecutive rows, or more than two consecutive second rows, for example of three consecutive second rows, when one moves around the longitudinal axis of the soul. By "average length of the teeth of a row" is meant the average of the lengths of the teeth of the row measured from their base and up to their free end, along an axis of elongation of the tooth. By "length of a tooth" is meant the distance measured along the axis of elongation of the tooth between the free end of the tooth and its base by which it is connected to the core. The term "axis of elongation of the tooth" designates an axis which passes through the centroids of the transverse sections of the tooth. In the same row, two teeth may have identical or different lengths. A row of teeth extending along the longitudinal axis may have at least three teeth of the same length. The application member according to the invention may comprise teeth whose free ends are equidistant from the center of symmetry of the cross section of the core or, failing this, of its barycenter, on at least one section of the core. 50% or more, 75% or 100% of the length of the portion of the core carrying the teeth. The angular difference between two consecutive rows, measured at the base of the teeth at their connection to the core, is between 15 ° and 60 °, or between 15 ° and 50 °, better between 20 ° and 45 °. The applicator according to the invention is thus devoid of areas around the core that would be toothless over a large angular space, especially greater than 60 °, better 50 °, better still 45 °. For the purposes of the present invention, the term "angular difference defined by two rows" denotes the minimum angle around the longitudinal axis, between the longitudinal axes of the two rows concerned, that is to say between the centers of bases of the teeth of the two rows concerned when in each row the teeth are aligned on a straight line.

Since the longitudinal axis of a row is considered on the surface of the core, two longitudinal axes of two consecutive rows, when moving around the longitudinal axis of the core, can be angularly separated from one another. angle less than 60 or even less than 50 °. for example of the order of 45 °, for example of the order of 30 °, or less. The axes of the rows may be parallel to the longitudinal axis of the core. When the soul is observed along its longitudinal axis, the passage from one row to another can be effected by a rotation of an integer submultiple of 360 ° about the longitudinal axis of the core, for example a rotation of 360 ° / n, where n is an integer between 5 and 20 for example.

In a first row, the teeth may not all be identical to each other. In a second row, the teeth may not all be identical to each other. The application member can be connected by a rod to a gripping member, the gripping member advantageously comprising means for locating the positioning of the applicator member relative to the user, in particular allowing the user to identify a possible rotation of the applicator relative to the user and thus to memorize the angular path performed. The marking means can thus allow the user to memorize the rotation of the applicator member with respect to its longitudinal axis which has been necessary so as to obtain a satisfactory makeup for the user. Such a registration can thus make it possible to reproduce a rotation of the same amplitude later, for example to obtain a close or identical make-up. The locating means may comprise angular marks, the number of angular marks being able to correspond, for example, to the number of alternations between the first and second rows, or to the number of first rows, or to the number of second rows, for example. or be a submultiple of the number of first rows and / or the number of seconds rows for example. The locating means may comprise a graduation staggered about a longitudinal axis of the applicator. The graduation may for example be quantified, for example by means of alphanumeric characters such as numbers or letters, or by means of colors, for example arranged in a gradient, or for example by means of symbols. The graduation may for example allow the user to identify the value of the angle of rotation undergone by the applicator relative to the user. The staggering can extend over 180 °. The applicator may comprise two graduations each staggered over 180 °, and which may be symmetrical to one another with respect to a plane of symmetry containing the longitudinal axis of the applicator. In this case, the direction of rotation chosen during use may have some importance, and affect the resulting makeup. The marking means may alternatively not be indexed with respect to the applicator member, and in particular to the teeth of the latter, or even to the first and second rows. In other words, the application member may in particular not have a predefined angular position relative to the locating means. The locating means may alternatively or additionally comprise several reliefs of the gripping member. These reliefs can help to help the user to slightly change the orientation of the applicator member with respect to the eyelashes. The number of reliefs arranged circumferentially around the gripping member when moving around the longitudinal axis of the applicator may for example correspond to the number of alternations between the first rows and the second rows, or be a sub-multiple of the number of. first rows and / or the number of seconds rows for example.

Envelope Surface The free ends of the teeth of the applicator member define an envelope surface of the applicator member. The envelope surface may be substantially symmetrical in revolution, for example substantially cylindrical in revolution. The envelope surface may, if appropriate, extend according to a. longitudinal axis forming a non-zero angle with the longitudinal axis of the core. The largest transverse dimension of the envelope surface of the applicator member, measured perpendicularly to the longitudinal axis of the core, may be between 3 and 14 mm.

The envelope surface may be of greater transverse dimension substantially constant over at least a portion of the length of the applicator member, in particular over more than half the length of the portion of the core bearing teeth.

The envelope surface may also have a cross section that varies over all or part of the length of the applicator member. This can for example admit one or more extrema and for example at least a local minimum and two maxima. The envelope surface may for example have a peanut shape when the applicator member is observed on the side, in a direction perpendicular to its longitudinal axis. Soul, stem and tip The core may have a cross section of constant shape or not when moving along the longitudinal axis of the soul, for example at least half, even three quarters or the the entire length of the portion of the soul carrying the teeth. The section may for example vary homothetically. When moving from the proximal end towards the distal end of the applicator member, the cross section of the core may, for example, increase or decrease monotonously. When moving from the proximal end to the distal end of the applicator member, the cross section of the core may have an extremum, for example a minimum or an absolute maximum. The core may have a non-circular cross-section over most of its length. The soul may be of symmetrical general shape of revolution or not. It may not be cylindrical of revolution and be devoid of reliefs other than the teeth. The core may have on at least a portion of its length a cross-section of a shape selected from the following list: circular or non-circular, semi-circular, elliptical, oblong, semi-elliptical, polygonal, square, hexagonal, octagonal, semi -polygonale. This weasel may vary as one moves along the longitudinal axis of the soul.

The soul can have a variable profile, when observed perpendicularly to its longitudinal axis. The core may in particular have a transverse dimension reaching an extremum substantially mid-length. This can give the soul rigidity or increased flexibility and allow to define an envelope area of variable section along the applicator member, especially when the length of the teeth is constant in a row. at least on a portion of the application member. The soul may have at least one longitudinal twisted face. The applicator member may have a helical distribution of the teeth on the core, directed towards the right 2968519 L3 or to the left when progressing towards the distal end of the applicator member. The soul can admit, in at least one transverse sectional plane, an axis of symmetry which is for example its longitudinal axis. The core may comprise a recess in which is engaged a support portion, constituted for example by the rod, for example metal or plastic. The core may be configured to be fixed to this support portion or to be free in rotation or translation relative to this support portion. The core may be connected to a rotatable portion of the gripping member movable relative to a fixed portion of the gripping member. In this way, the user can at will change the orientation of the gripping member relative to the eyelash fringe by rotating the rotatable portion relative to the fixed portion of the gripping member. In a variant. the portion of the soul that bears the teeth is full. The core may comprise only a tip or housing at one of its ends to allow its attachment to a rod connected to a gripping member. The core and the teeth may be molded from the same material, or alternatively may be made of at least two different materials. A portion of the core and teeth may for example be made of a first material and another portion of the core and teeth may be made of a second material, for example softer or harder than the first. . The core is for example formed of one or more thermoplastics, which may be elastomeric. In exemplary embodiments of the invention, the teeth are made by molding or overmoulding with the core. Teeth can, for example. be made by protrusion, in which there is injection of a material through at least a portion of the core, so as to allow the formation of teeth. The applicator member may be attached to a rod connected to a gripping member of the applicator. for example by snapping. gluing, welding. crimping. stamping, forced insertion, cold or hot, for example by mounting in a. housing 30 of the rod. Alternatively, the rod can be received in a housing provided in the core. The rod and the applicator member may also be molded in one piece, in the same thermoplastic material or not.

The core may extend along a longitudinal axis making at least one point of its length an angle with the longitudinal axis of the rod to which is fixed the core. The applicator member may be bent at its connection to the rod. The rod may comprise a first portion, rigid, extended distally, by a second portion, more flexible, for example elastomer, carrying the applicator member. The applicator member may comprise a mounting piece integrally molded with the core, which may optionally include one or more narrowed portions to improve applicator flexibility and flexibility. application. The invention further relates, in another of its aspects, independently or in combination with the foregoing, to an applicator for the application of a product to the eyelashes and / or the eyebrows, comprising an organ of application, in particular unmolded, for example a twisted brush, comprising: a core having a longitudinal axis, in particular a core formed of a U-folded twisted metal wire; and bristles extending from the core . comprising first and second hairs different from each other, differing for example from each other by their length and / or the shape of their free end and / or their diameter. The first and second hairs may differ in length. In this case, the application member can have a multilohé form. A succession of ridges can be encountered when moving on the surface of the applicator member about the longitudinal axis of the core. Alternatively, the first and second bristles may differ in the shape of their free end. The first hairs may for example be of generally cylindrical shape, having an undeformed free end, which may have undergone no treatment. The second bristles may comprise a deformed free end, having undergone a treatment. for example having balls obtained by heating the applicator member at the end of the bristles so as to melt the end thereof. The balls may for example allow to bring a larger amount of product. Alternatively, the treatment can be used to form forks or hooks at the end of the bristles, which can be obtained by mechanical treatment, for example grinding of the applicator member. Of course, the first and second hairs may differ by more than one of the characteristics mentioned above. The first hairs may for example be S longer than the second hairs, the second hairs being shorter and having a deformed end, for example a ball. Longer hairs may provide the separation characteristics mentioned above, while deformed bristles may provide the above mentioned load characteristics. When moving in a cross section of the brush around the longitudinal axis of the soul, successively there are first hairs then second hairs, a succession of the first hairs followed by second hairs renewed at minus three times when moving around the longitudinal axis of the brush. The free ends of the first bristles may be distributed over an angular extent measured at the end of the bristles around the longitudinal axis of the core between 15 and 60 °, or even between 15 and 50 °, better still between 20 and 45. The free ends of the second bristles may be distributed over an angular extent measured at the end of the bristles around the longitudinal axis of the core between 15 and 60 °, or between 15 and 50 °, better between 20 and 45 ° . The applicator according to the invention has no zone around the core which would be devoid of bristles over an excessive angular space, in particular greater than 60 °, more preferably 50 °, more preferably 45 °. The angular expanses on which the first and second hairs extend, that is, the angular extent of the lobes or ridges, may be equal or, on the contrary, differ. The application member may for example comprise on a first angular extent only first bristles and on a second angular extent only second bristles. The first and second angular extents may be arranged alternately as one moves in a cross section of the applicator member about the longitudinal axis of the core. The value of the angular ranges may, for example, be equal or alternatively different. For example, it can vary progressively when one moves around the longitudinal axis of the core in a cross section.

Packaging device The invention further relates to a device for packaging and applying a cosmetic or care product, for example a mascara, to keratinous fibers, in particular eyelashes or eyebrows, comprising an applicator such as defined above, a container and a wiper member, preferably configured to allow uniform wiping of the applicator member when leaving the container. The gripping member of the applicator may constitute a cap for closing the container. The wiper member may be adapted to dewater the rod and the applicator member. The invention makes best use of the product contained in the container, insofar as more product on the applicator member can be used at each outlet of the applicator of the container. The solvent losses are reduced, so the amount of product and / or solvent can be reduced for the same overall duration of use. The product may be a mascara, for example a water-resistant mascara or a mascara resistant to rubbing. The applicator member may be configured to create a piston effect in the container, i.e. a maximum cross section of the envelope surface of the applicator member may occupy at least 70% of the the inner section of the container at least along a portion of the path traveled by the applicator member during its extraction from the container, the height of this portion being at least equal to twice the length of the body of the container. application, for example between two and ten times the length of the applicator member, as described in international application WO 2009/153753. The device may be configured so that the applicator member is spaced a distance of less than 1.5 mm, more preferably less than 0.5 mm, from the interior surface of the container when the applicator is in place on the container in a storage position. Teeth and rows of teeth The largest teeth of the applicator member may be of length between 1 and 6mm, for example 1.7 and 4.5mm. More than half of the teeth may have a length as defined above, better at least 60%, even at least 70%, or even all of the teeth.

The length of the teeth of at least one row may vary, for example monotonically, within a row as one moves along the longitudinal axis of the core. For example, as one moves along the longitudinal axis of the soul, the length of the teeth within at least one row may increase between the proximal end and a first abscissa and then remain substantially constant between this first abscissa and a second abscissa and then decrease between this second abscissa and the distal end. For example, the length of the teeth within at least one row may admit two maxima. Two teeth of two different rows having the same abscissa measured on the longitudinal axis of the core may have substantially the same length, the better all the teeth having the same abscissa have the same length. Teeth, or even all the teeth, may have a cross section of semi-circular, or semi-elliptical shape. A shape with a flat, such as semi-circular or semi-elliptical can facilitate demolding of the application member, the flat being coincident with the joint plane. At least one tooth may have a circular cross section, with or without flat, or. non-circular, flattened, star-shaped, for example cross-shaped or with several branches, U-shaped, H, T or V, a recessed shape, for example circular square, forming branches, for example in shape flake, a prismatic shape, for example triangular, square or hexagonal, an oblong shape, especially lenticular or hourglass-shaped, polygonal, regular or not, including square, rectangular, octagonal, parallelogram, rhombus or oval. At least one tooth may have at least one relief, in order to improve the adhesion of the product to the tooth. The cross section of the tooth can decrease homothetically away from the core, for example more than half the length of the tooth. The teeth of the applicator, or all the teeth, may have a thickness measured at their base, that is to say at the point of connection of the teeth to the core, between 0.2 and 0.8 mm, even between 0.3 and 0.5 mm. By "thickness of a tooth" is meant the largest transverse dimension of the tooth, in section perpendicular to the axis of elongation of the tooth. The choice of the thickness of the teeth may be made for example depending on the type of makeup sought and / or the nature of the eyelashes and / or the rheology of the product.

Teeth can be of any shape. The teeth may have a cylindrical or tapered shape, in particular frustoconical or pyramidal shape. At least one tooth may have an at least partially frustoconical profile, for example terminated by a rounded free end, so that the cross section of the tooth decreases from its base towards its free end. The applicator may have between 75 and 500 teeth, for example. Within a row of teeth, the number of teeth can be between 6 and 60, in particular between 10 and 50. At least two teeth can define, when the applicator is viewed from the side perpendicular to its longitudinal axis, a V-groove. At least two consecutive teeth of a row of teeth may have first longitudinal faces having the same first shape, for example flat, in particular at least at a lower portion of the tooth, and second longitudinal faces. having the same second faith, for example non-planar, in particular rounded. The first faces can be oriented in the same direction of rotation around the soul, that is to say all be directed in the same clockwise or counterclockwise direction, when the soul is observed along its longitudinal axis. The first faces of the teeth, especially when they are flat, can be connected substantially perpendicular to. the corresponding face of the soul, at least 20 for some teeth of the row. At least one tooth, or even each tooth, may have a flat face parallel to its direction of elongation. Teeth can cross each other. The teeth may be rectilinear or not, extending for example each in a direction of elongation for the tooth which is rectilinear, or curve, for example corrugated. The teeth may extend in at least four different directions around the longitudinal axis of the core. The teeth may extend from the radial web, i.e., along an axis of elongation passing through the longitudinal axis of the web, or perpendicular to the surface of the web. soul, or at an angle between 0 and 90 ° with the latter.

At least one tooth of a row may extend, at least at its portion connecting to the core, or over its entire length, in a first direction Z1 perpendicular to the longitudinal face of the core to which the tooth connects or makes a small angle with the normal to said core surface, for example less than 10 '. better at 5 °. A tooth of a consecutive row or the same row in the case where it is a multiple row. for example a row of angles, can extend, from the same face of the soul, in a second direction Z2, at least at the portion connecting to the soul, or over its entire length, making a non-zero angle with the first direction, when the soul is observed along its longitudinal axis. The angle α between the directions Z1 and 1.0 Z2 can be between 5 and 80 °. The length of a row may be between 10 and 45 mm, especially between 15 and 35 mm, or even between 20 and 30 mm, being for example about 25 mm. The teeth may be made of a more or less rigid material than a material used to make the rod of the applicator to which the core is connected. The invention also relates to a process for making eyelashes or eyebrows using an applicator as defined above.

FIG. 1 shows a device 1 for packaging and application made in accordance with the invention. comprising an applicator 2 and an associated container 3 containing a product P to be applied to the eyelashes and / or the eyebrows. for example mascara or a care product. The product may be for example a water-resistant mascara, or a mascara resistant to friction. The container 3 comprises, in the example in question. a threaded neck 4 and the applicator 2 comprises a gripping member 5 also constituting a closure cap arranged to attach to the neck 4 to close the container 3 in a sealed manner in the absence of use. The applicator 2 comprises a rod 7 of longitudinal axis Y, which is connected at its upper end to the gripping member 5 and, at its lower end, to an applicator member 8. The latter comprises a core 10 carrying Teeth 18. The container 3 also comprises a wiper member 6, for example inserted in the neck 4. This wiper member 6, which may be arbitrary, comprises in the example in question a lip 6a arranged to dewater the rod. 7 and the applicator member 8 when the applicator 2 is removed from the container 3. The lip 6a defines a wiper orifice of diameter adapted to that of the rod. In the example shown, the rod 7 has a circular cross section but it is not beyond the scope of the present invention when the rod 7 has another section, the attachment of the gripping member 5 on the container 3 can then be otherwise than by screwing, if necessary. The wiper member 6 may be adapted to the shape of the rod 7 and that of the applicator member 8, if appropriate. In the example considered, the longitudinal axis Y of the rod 7 is rectilinear and coincident with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it is not beyond the scope of this invention when the rod 7 is non-rectilinear, forming for example a bend.

The rod 7 may comprise, where appropriate, an annular necking on its portion which is positioned opposite the lip 6a of the wiper member 6, so as not to mechanically stress it excessively during storage . The applicator member 8 may comprise, as illustrated, a tip .9 allowing its attachment in the rod 7. In the embodiment of Figures 1 and 2, this nozzle 9 is symmetrical of revolution, being of cross section circular, but could be of another form. The attachment of the applicator member 8 can in particular be done by force fitting, in particular latching, by gluing, welding or crimping, in a corresponding housing provided at the end of the rod 7. In a variant, the rod can be inserted in a dwelling planned in the soul. The core 10 can be made in one piece by molding material with the rod 7.

The core 10 may be of elongated shape extending along a longitudinal axis X. As in the example under consideration, the core 10 may present, over the majority of its length, a polygonal cross section whose sides define longitudinal faces 15 In the example of Figures 1 to 5, the core 10 has a hexagonal cross section.

The longitudinal axis X is for example central, as illustrated. It is possible to use for molding the applicator member 8 a thermoplastic material that is relatively rigid or not, particularly flexible, for example SEBS, silicone, latex, butyl, EPDM, a nitrile, a thermoplastic elastomer, a polyester, polyamide, polyethylene or vinyl elastomer, a polyolefin such as PE or PP, PVC, EVA, PS, PET, POM, PA or PMMA. In particular, materials known as Hytrel®, Cariflex Alixine®, Santoprene®, Pebax® can be used, this list not being limiting. The application member may also be made of metal. The teeth 18 are made in the example considered in one piece by molding thermoplastic material with the core 10. The teeth and the core can be made of different materials, if necessary. The teeth 18 are arranged in rows 17 of teeth having different spacings. The rows 17 of teeth comprise in particular first rows 17 '20 having teeth 18 spaced apart from each other with a first gap e], and second rows 17 "whose teeth 18 are spaced apart from each other with a second spacing e2 the second gap being different from the first gap, as illustrated in FIGS 3 and 3. More specifically, in the illustrated example, the first gap and is smaller than the second gap e2. The invention comprises alternating first rows 17 'alternating with second rows 17'. when one moves around the longitudinal axis X of the core, as can be seen in FIGS. 3a and 4. It can be seen in FIG. 4 that the applicator member has faces 15 each comprising In the example illustrated, the first and second rows differ in the spacing of the teeth in the row, but it is not beyond the scope of the present invention if it is otherwise. for example the first and second rows differ by at least one of the spacing of the teeth in the row, the number of teeth in the row, the implantation of the teeth in the row, the thickness of the teeth, the shape of the teeth. As a further variant, the teeth of the first and second rows disposed on one side of the core may have a first length, and the teeth of the first and second rows arranged on the other side. of the soul can have a second different length first, as shown in Figure 3e. Such a configuration makes it easy to alternate two types of makeup by slightly turning the applicator member 10 relative to the fringe of the eyelash. 10. When using the rows 17 'having the first spacing, the separation of the eyelashes is favored, the teeth being narrowed, and when the rows 17 "having the second spacing are used, the loading of the product is facilitated. on the eyelashes, the teeth 18 of the rows 17 "being further apart, which allows a greater product storage between them. The rows 17 'or 17 "may be grouped by two rows 17 having the same spacing as one moves around the longitudinal axis X of the web 2. The two rows 17 may constitute, as illustrated in FIGS. and 5, a first row 17a and a second row 17b axially offset relative to the row 17a, Each face 15 may, as shown in Figure 5, have a first row of teeth 17a connecting at an angle O (with the normal to the corresponding face 15 of the core 10, and a second row of teeth 17b obliquely connecting to this face 15, making an angle αZ2 with this normal.The teeth 18 of the row 17a extend in one direction Zf substantially perpendicular to the face 15, the angle azi being relatively small, for example less than 10 °, or even 5. The teeth 18 of the row 17b are also straight in the example considered, extending according to a Z2 direction form an angle α with the direction Z1, the angle a is for example between 20 and 80 °. The teeth 18 of the rows 17a and 17b may be separated by a geometric separation surface S, this surface S being for example a bisecting plane of the angle α, so as to faith a double row. Furthermore, as can be seen in FIG. 4 in particular, each tooth 18 may comprise a first longitudinal face 40 of planar shape and a second longitudinal face 41 of rounded shape, in particular in the shape of a half-cone.

As a variant, the two rows 17 'and the two consecutive rows 17' 'having different spacings may each be rows not axially offset, as illustrated in FIG. 3b. In another variant, they may constitute rows of V-shaped teeth, as shown in FIG. illustrated in perspective in Figure 3e. "Alternatively, the first and second rows may for example differ by the implantation of the teeth in the row. By way of example, FIG. 3d illustrates an applicator member comprising first rows 17 'comprising V teeth, and second rows 17' 'of teeth arranged radially.

Furthermore, the average length of the teeth of a row may be substantially constant from one row to another. More precisely, the length of the teeth is substantially the same, as can be seen in FIG. 4, as one moves around the longitudinal axis X of the soul. It can be seen in FIG. 4 that the teeth 18 of the rows 17 having the same abscissa measured along the longitudinal axis X have the same length 1.

The length of the teeth 18 may decrease closer to the distal end 12 of the core 10. The length of the teeth 18 may also decrease when the lion approaches the tip 9, so as to facilitate the crossing of the body. spin 6 by the applicator member 8 when removing the applicator 2 from the container. FIG. 4 shows in particular that consecutive rows closest to teeth 18 define between them an angular difference y. The angular difference is in the invention between 15 and 60 °, better between 15 and 50 °, more preferably between 20 and 45 °. It may be of the order of about 30 ° for example. Such angular deviation corresponds substantially to an intuitive rotation performed by the user to slightly shift the rows relative to the fringe back lashes.

The applicator further advantageously comprises locating means 20 on the gripping member, which make it possible to locate the positioning of the applicator member 10 relative to the user, so as to identify a possible rotation of the applicator with respect to the user and thus to memorize the angular path carried out. In the example illustrated in FIGS. 1 to 4, the marking means 20 comprise colored pellets arranged circumferentially around the gripping member 5 and whose color is regularly degraded.

Of course, it is not beyond the scope of the present invention if the color chips are distributed differently, or are not colored but are only degraded from black to white, as shown in Figure 6a. In another variant. the marking means 20 may comprise a scale comprising graduations, for example alpha numeric. By way of example, FIG. 6b illustrates a scale comprising digits from 0 to 5. In this variant embodiment. the scale is staggered over 180 ° and the marking means comprise two scales each scaled 180 °. being symmetrical to one another with respect to a plane containing the longitudinal axis X.

In another variant. the gripping member 5 is devoid of any alpha numeric or colored indication. The marking means 20 may consist solely of reliefs of the gripping member. In the embodiment illustrated in FIGS. 7a and 7b by way of example, the gripping member comprises longitudinal ribs 21 distributed circumferentially around the gripping member 5. These ribs 21 allow the user to arrange his fingers D intuitively on the gripper and easily move them during use, as shown in dashed lines in Figure 7b. In another variant, the locating means may also comprise. in addition to the reliefs, at least one origin mark 22, as shown in dashed lines in FIG. 7a. In another variant, the gripping member 5 can comprise a fixed part 5a and a movable part Si, which can be rotated relative to the fixed part 5a by the user. For this purpose, the mobile part 5b may include pins 5c, as illustrated in FIG. 8. The applicator may in this case comprise an applicator member 10 fixedly connected to the rotary part 5b by a mobile part 7b of the rod 7. being engaged on a fixed part 7a of the rod 7 itself connected to the fixed part 5a .. When the user rotates the movable portion 5h relative to the fixed portion 5a of the gripping member 1 gripping member 10 is also rotated relative to the fixed portion 7a of the rod.

In the embodiment illustrated in FIG. 8a, the fixed part 5a of the gripping member comprises a pawl 30 adapted to cooperate with indentations 31 formed on the movable part 5b.

To use the device I, the user can unscrew the closure cap 5 and extract the applicator member 8 from the container 3. After passing through the applicator member 8 of the wiper member 6, some quantity of product remains between the rows 17 and between the teeth 18 of these rows.

The user is made to rotate at least once, or at least twice or more, the applicator member around the longitudinal axis X of the core relative to the user during use, between two successive applications of product. without reloading the application member into product. Such a displacement of the fingers D with respect to the gripping member 5 is illustrated in FIG. 7b in one example of the embodiment. It is possible to successively modify the position of the fingers on the gripping member without resting the applicator. The user can make such a displacement as many times as necessary until the number of successive layers applied seem to him sufficient to obtain a satisfactory makeup.

The core 10 may have a circular cross section, as shown in Figure 9, elliptical. as shown in Figure 9a, hexagonal, as shown in Figure 9d, octagonal, as shown in Figure 9b or pentagonal, as shown in Figure 9c. Whatever the implantation of the teeth, at least one tooth may have a semicircular cross section, as illustrated in FIG. 10.

The teeth are preferably of cross section other than circular. A non-circular shape of the cross section of the teeth. can promote product retention on the teeth. In an alternative embodiment, the longitudinal faces 15 of the core 1 () are twisted, as shown in FIG. 1.1. To realize such faith e. the core 10 may be deformed at the time of demolding by a rotation of the nozzle 9, or alternatively be deformed in the mold. The longitudinal axis X of the core 10 may coincide with the longitudinal axis Y of the rod 7, but it is not beyond the scope of the present invention if it is otherwise, and by way of example, illustrated in Figure 12 an alternative embodiment in which the longitudinal axis X of the core 10 forms an angle j3l with the longitudinal axis Y of the rod. Such a configuration can for example improve the ergonomics of the applicator. The applicator may extend along a non-rectilinear longitudinal axis X. FIG. 13 illustrates an alternative embodiment in which the core extends along a longitudinal axis X curved. When observed in longitudinal section, as in FIG. 13, the envelope surface E may have on one side of the X axis a first convex profile 54 substantially in the same direction as the X axis, and on the opposite side of the X axis. X axis, a second profile 55 may have a concave curvature in the same direction as the X axis.

The envelope surface may be conical, frustoconical, shaped fish, diabolo, pear, lenticular, or other. The envelope surface may be of non-cylindrical shape passing through a maximum or two maxima. In the variant illustrated in Figure 13a, the envelope surface E has two longitudinal profiles 54 and 55 opposite, one 54 is straight. Alternatively, the envelope surface E may have a cross section that passes through two maxima and a local minimum, as illustrated in Figure 13b, or by a maximum, as shown in Figure 13e. In another variant, illustrated in FIG. 13d, the envelope surface E extends generally along a longitudinal axis W forming an angle y2 with the longitudinal axis X of the core 10. The variant of FIG. 13e differs from that of Figure 13d by the shape of the envelope surface E, which has a cross section that passes through a minimum. The longitudinal axis X of the web 10 may be rectilinear and at an angle to the longitudinal axis Y of the rod 7, as illustrated in FIG. 13f, the envelope surface E having, for example, a non-constant cross section, for example. example passing through a minimum.

In the embodiment shown in Figure 14, the core 10 has a recess in which is engaged a support portion 60, for example metal or plastic. The core 10 may be configured to be fixed to this support 60 or to be free in rotation or in translation relative to this support 60. The core 10 may for example be overmoulded on the support 60. At least one of the teeth 18 of the rows 17 may have a non-smooth surface condition, for example molded striations or asperities, for example related to the presence of a load in the plastic material. The applicator member may be made of a plastics material comprising magnetic particles. The magnetic field created by such particles, which may be magnetizable and / or magnetized, may interact with magnetic fibers or pigments that would be present in the product. The applicator member can be made with flocking, the latter extending for example only on the teeth or on the core only.

The teeth may have, at their free end, a relief or a particular faith, for example a fork, a ball or a hook, as respectively illustrated in Figures 15, 15b and 15a. The hook may extend for example transversely, parallel or obliquely to the longitudinal axis X of the core. To obtain the balls, one can for example heat the applicator member so as to melt the end of the teeth. To obtain the forks or hooks, it is possible to mechanically treat, for example grind, the application member and thus abrade the ends of the teeth. The application member may include any bactericidal agent such as silver salts, copper, preservatives and at least one preservative of the product such as parabens or other preservatives. The soul and / or the teeth can. in addition, comprise particles, for example a filler including a magnetic compound, bacteriostatic or moisture absorber or a compound for creating on the surface of the tooth roughness or to promote the sliding of the eyelashes on the teeth. At least one of the core and a tooth can be flocked, receive any heat treatment or mechanical, and / or comprise particles, for example a load, in particular to improve sliding.

The wiper member may comprise a wiper orifice of circular cross-section, oval, square, or triangular. The wiper member may comprise one or more slots, the slot or slots being radial (s) or tangential (s) to the orifice. The wiper member may be made differently, for example comprising a block of foam, which can be split. The wiper member may, for example, be as described in patent applications US 2005/0028834, US 6328495, US 6375374, US 2004/0258453 and US 2005/0175394. In particular, the wiper member may be rigid or of elastomeric material.

The wiper lip 6a may advantageously be corrugated, having a radially inner free edge defining a passage opening 122 of the applicator member, as illustrated in FIG. 16. The wiper lip 6a may comprise corrugations 120 extending around the orifice 122. The wiper member 6a may comprise a number of corrugations 120 of between 3 and 12, for example.

The wiper lip 6a may extend generally in a cone converging toward the bottom of the container, generatrix G at an angle i with the axis K of the container. Alternatively, the wiper lip 6a may extend generally along a median plane perpendicular to the axis K or generally according to a convergent cone in the direction of the outlet of the container.

The wiper member can still be adjustable, if necessary. The rod 7 to which the core is attached may be at least partially, especially entirely flexible, for example near the applicator member. The rod may for example comprise at. at least one flexible element 80 as shown in FIG. 17, for example made of elastomer and / or with a shape conferring flexibility, for example at least one notch 81 as illustrated in FIG. 17a. The application member can be made by any known method such as injection, lai-injection and protrusion, in which there is injection of a material through at least a portion of the core, so that to allow the formation of teeth.

The applicator member may alternatively be molded but have bristles retained in a core, for example a twisted metal core consisting of a U-folded and twisted wire.

As an example, FIGS. 18a to 18d illustrate transverse sections of applicator members having first bristles 18a and second bristles 18b which are alternately arranged as one moves around the applicator. longitudinal axis of the soul.

By way of example, in the embodiment of FIG. 18a, the second bristles 18b differ from the first ones 18a by their free end which comprises a ball formed by heating the free end of the second bristles. The first hairs extend over first angular extents y1, y1 'and y1 "and the second hairs extend over angular second stretches y2, y2', y" 2. In the example shown, the angular ranges y1, 72, yj ', y2', y1 "and 72" are equal. The bristles may alternatively differ other than by their free end, for example by their length, as shown in Figure 18b. In this example, the first hairs 18a are longer than the second hairs 18b. As a further variant, they may differ both in their length and in their free end, as illustrated in FIG. 18e, in which the first bristles 18a are long and not deformed at their free end, and the second bristles 18b are shorter. and deformed at their free end, with balls. In another variant, the angular extents may vary. They may, for example, vary progressively as one moves all around the longitudinal axis of the core in a cross section, as illustrated in FIG. 18d, where they increase progressively. The applicator member may be vibrating, that is to say that it may be applied to it during application, combing or sampling of the product, for example as described in application WO 2006/090343.

In another variant, the applicator member may be heating, that is to say include a heating element. It is also possible that the application member is vibrating and heating or only vibrating or only heating. Of course. the invention is not limited to the embodiments which have just been described, the characteristics of which can be combined within non-illustrated variants.

The expression "comprising one" must be understood as being synonymous with "comprising at least one" and "between" means included limits. unless the opposite is specified.
