Description

"APPLICATOR FOR THE APPLICATION OF A LIQUID PRODUCT AND SET OF MAKE-UP PROVIDED BY SUCH APPLICATOR" Inventor (s): JEAN-LOUIS GUERET, French, domiciled at 15, Rué Hégésippe Moreau, 75018 Paris, France.

Causaire: L'OREAL, French company, domiciled at 14, rue Royale, 75008 Paris, France. 1 FIELD OF THE INVENTION The present invention relates to an applicator for the application of a liquid product, such as a nail varnish, a liquid color for lips, a foundation for liquid make-up or a hair dye, as well as to an assembly or assembly of makeup provided with such an applicator.

BACKGROUND OF THE INVENTION In general, a set or equipment for make-up comprises a reservoir for the product to be applied, and a member for the application of said product, which includes an application member consisting of bristles which are arranged substantially parallel to each other. another, in the form of a bundle, and are fixed to a support called the applicator rod. This applicator is, in principle, a brush. This assembly Q further comprises a sleeve or sleeve designed to enclose the reservoir, the applicator rod in this sleeve is fixed so that the bundle is immersed in this product. The brushes provided to date n for the application of a layer of varnish to the nails, leave much to be desired with respect to the uniformity and smoothness of application, and the speed of make-up, especially in the uniformity and speed of application of a varnish to the nails, this being unsatisfactory from an aesthetic point of view. In this way, with a conventional varnish brush for nails, a layer of varnish is often deposited, which is not uniform, but marked by stripes that come from the bristles of the brush. This effect is more pronounced when a second layer of varnish is deposited on the nails, when the first has not been completely dried. In addition, with a conventional makeup brush it is usually necessary to immerse the brush several times inside the container, holding the product in order to paint one nail after the other, since the load of the product collected with the brush is relatively small. Various solutions have already been proposed in order to remedy this drawback, for example the incorporation of a type of deposit on the brush rod, as described in French Patent Document No. FR-A-2, 585, 934, but this solution complicates the manufacture and use of the brush, and is relatively expensive. In order to remedy these drawbacks, < It could be conceivable to lengthen the bristles, but in this case the bristles move very separately, which does not allow the precise application of the makeup.

BRIEF DESCRIPTION OF THE INVENTION The aim of the present invention is, in particular, to provide a makeup applicator which allows the makeup to be applied quickly, while at the same time carrying much more product than a conventional brush, in this way, this applicator has greater autonomy and makes It is possible to deposit a thicker layer than with a conventional brush, which results in greater ease of application for the user. After many experiments, the Company Applicant has observed that, by varying the flexibility of the rod of such an applicator, it was possible, surprisingly, to apply a more uniform layer of makeup product, especially when this is a targeted applicator for the application of a nail varnish. In addition, for the deposit of a second layer of varnish it is not necessary to wait for the complete drying of the first one. The Applicant Company has observed that, by varying the flexibility of the rod of an applicator, it was possible to obtain a much more uniform layer of varnish on the nail than with an applicator having a rigid rod., without the formation of scratches on the varnish layer deposited on the nail. In this case, it was observed that the applicator pulls the product on the surface of the nail by the capillary effect. Accordingly, the application member "floats" on the deposited varnish layer, without scratching and without scratching. In addition, it even removes all types of stripes, and a second layer can be applied just after the first layer has been spread, without waiting for it to dry, which shortens the total application time. Likewise, the Applicant Company has observed that it was possible to use a more rigid application member than one conventionally used, which allows the use of varnishes having a viscosity outside the normally used range. Surprisingly, it has been observed that the appearance of the makeup obtained in this way was more lustrous, that the mechanical strength of the applied layer, after drying, was increased, and that the binding capacity of the varnish to the nail was increased.

DETAILED DESCRIPTION OF THE INVENTION Thus, the invention relates to an applicator for the application of a makeup product, which includes an application member having a defined flexibility, this member is fixed to one end of a rod, characterized in that the rod has a flexibility similar to that of the application member. By the phrase "flexibility similar to the application member" is meant a flexibility such that, when the product is applied to a surface, for example a varnish to a nail, the application member and the flexible part of the rod form a curve with a virtually constant curvature, especially in the form of an arc of a circle. This flexibility of the rod is chosen, especially, so that the force F to be applied in order to flex the rod falls within the range of: 0.3f less than or equal to F less than or equal to 3f, where f is the force required to double the application member. Preferably, the flexibility of the rod is chosen to be more similar to that of an application member. According to the invention, the rod has an advantageously chosen length of the range ranging from 2 to 20 cm, preferably from 2 to 4 cm, and this has a diameter that falls within the range of 2.5 to 5.0 mm, preferably 2.5 to 3.5 mm. According to a first embodiment, the flexible rod is made of an elastomeric material. Advantageously, this material is chosen from the group of polyethylene, polyurethane, polyester elastomeric; polyether amides in block; polyvinyl; terpolymers of ethylene, propylene and a diene (EPDM); block copolymers of styrene-butadiene (SEBS-SIS). In particular, the elastomeric material has a hardness that falls within the range of 35 to 90 Shore A, preferably 50 to 70 Shore A. The rod may include at least one region of smaller cross section; this small cross section falls, for example, within the range of 0.2 to 1.8 mm, preferably 0.4 to 1.2 mm2, over a length in the range of 2 to 20 mm, for a maximum cross section that is in the range of 4 to 20 mm. mma, and preferably from 2 to 12 mm2. In other words, the small cross section is a cross section chosen so that the ratio S / s falls between 2 and 100, with s being the smallest cross section and S the largest cross section. According to a second embodiment, the flexible rod is produced, at least in part, from wire, for example a steel wire for piano whose diameter is chosen, for example, in the range from 0.15 to 1.0 mm, preferably from 0.15 to 0.3 mm, and whose length advantageously falls within the range of 0.5 to 8 cm, preferably from 1 to 4 cm. As a variant of this second embodiment, at least one region of the rod consists of a helical spring formed by turns that touch or do not touch. According to a third embodiment, the rod can be made of a relatively hard material, such as high density polyethylene or low density polyethylene (HDPE or LDPE), the hardness of which is chosen from the range of 90 Shore A to 40. Shore D, and preferably * > Under these conditions, the rod, when cylindrical, is provided in particular with at least one region of smaller cross section this small cross section has, for example, the dimension given hereinafter. 0 In particular, the rod may include, in the region of small cross-section, a flattened part, recessed, spiral-shaped or in the shape of an accordion, in order to make it more flexible. In accordance with the invention, the application member may be attached directly to the end of the rod. According to the invention, the application member can be a round, a bundle of fibers or a spatula. Advantageously, according to a first variant embodiment of the invention, the application member conventionally consists of a tuft of substantially parallel bristles. The tuft of bristles has, in particular, a length (L) in the range of 8 to 40 mm, and preferably of 11 to 20 mm. In this case, the applicator constitutes a brush. According to this variant, the nail varnish applicator preferably includes a tuft of about 100 to 1200, and preferably 120 to 500 sows of a diameter in the range of, for example, 4/100 to 25/100 of mm, and preferably from 6/100 to 17/100 of mm, these bristles being made of a polyamide, for example of nylon-6, nylon-6-6, nylon-6,10, nylon-6,12, or nylon -11, polyester, polymethacrylate, polyacetal or cellulose acetate. The bristles can, if it is required to be of natural origin. According to a second variant of the invention, the application member may consist of an elongated turn, a tuft of fibers or large bristles, or an application spatula which is flattened or is in the form of a cellular foam with cells open This application member can be provided, on its surface, with a velvety coating. Advantageously, this member is fixed to one end of the rod by adhesive bonding, for example, but the fixation can be achieved by any other known means. It is also possible to equip the applicator, according to the invention, with bristles made of thermoplastic elastomer chosen from the group of polyethylene, polyurethane, palyster elastomers.; of polyether amides in block; polyvinyl; terpolymers of ethylene, propylene and a diene (EPDM); block copolymers of styrene-butadiene (SEBS-SIS); silicone elastomers or nitrile elastomers. Advantageously, the thermoplastic elastomer has a Shore A hardness that falls within the range of 15 to 90, and preferably 30 to 60 Shore A. Under these conditions, its diameter is advantageously chosen from the range of 4/100 to 35. / 100 mm, preferably 10/100 to 20/100 mm. The material constituting the bristles may contain an agent that modifies its surface finish and / or its sliding characteristics, and / or reduces its wettability to water and / or solvent, or in addition an antistatic agent.

Advantageously, the agent that improves the sliding characteristics of the bristle and reduces its wettability to water and solvent, is incorporated within the material of the bristles in an amount falling between 0.2% and 15% by weight, preferably between 0.3 and 5% by weight. This slip agent is preferably chosen from the group consisting of polytetrafluoroethylene, boron nitride, molybdenum disulfide, graphite, silico-ies, fullerene, talc, etc. According to an advantageous aspect of the invention, the bristles have a first end obtained by flexing a fiber in a U, the base being the U held by a clamp pressed just inside a housing made in the free end of the applicator rod. Advantageously, this housing has the shape of a cylinder of revolution. It can also be designed to be shaped into an elongated or cruciform oval shape, or in the form of a semicircular tile. This housing can be widened towards the free end of the rod. The tuft of bristles can also be fixed within the housing of the applicator rod by bonding with adhesive, or by any other means normally used for the application of broaches, for example by means of a ferrule or sleeve. 1 At least part of the bristles may have slight corrugations on their length. The bristles may have cross sections whose shape is chosen from the group of circular, annular, polygonal, cruciform, rectangular or multilobal shapes, or shapes in the form of a U, in the form of a C or in the form of a V, or shapes that include at least one capillary notch. The free end of the bristles can be produced in the form of a pinhead, especially obtained by heat treatment, for example by means of a torch flame. The free end of the bristles can be made with a tapered shape, obtained, for example, by sharpening or by carding. The cross section of the applicator can r? having various shapes, it being possible for the tuft to have, especially, a circular cross-section, a cross-section in the form of a semicircular tile, an oval cross-section or a cruciform cross-section. The free end of the applicator 0 may be flat or rounded. The applicator having the features that have been just described, is particularly suitable for the application of a nail varnish, or a liquid make-up or a hair dye, especially a product having a high viscosity. In the case of a varnish, this may be a composition that may or may not include toluene or formalin; or may also include a solvent system comprising water and / or alcohols. The present invention also relates to a nail varnish application assembly, consisting of a reservoir, generally made of glass, equipped with a neck and with an integral sleeve or sleeve with a submerged application member, in the position of storage, in a varnish for nails contained in this tank, whose assembly is characterized in that the applicator member is an applicator, as defined above. The invention consists, apart from the arrangements discussed hereinabove, of a number of other arrangements that will be explained more closely, hereinafter in detail, with respect to the examples of the modalities described with reference to the attached drawings, but which are not limiting in any way.

With reference to Figure 1 of the drawings, one can observe a nail varnish assembly which comprises an applicator (1) for the application of varnishes, According to a first variant modality, the applicator (1) is provided with a tuft (2) of bristles (3), for example made of nylon-6.10, which is fixed to a free end (5a) of a flexible rod (5), and is oriented substantially along the axial direction of the rod. 1 The flexible rod is made of a thermoplastic material, for example, polyethylene; it is cylindrical and has a diameter of approximately 2.5 to 3.5 mm. Its length is especially 4 cm. A central region 5 (55), of smaller cross section in the range of 0.2 to 1.8 mm2, is provided on this rod, giving it a defined flexibility, similar to that of the tuft (2) of bristles (3). This region (55) can be observed more clearly in Figure le. A sleeve or cylindrical handle (6) is integral with the other end (5b) of the rod (5), opposite the lock (2), this end (5b) being formed in the form of a securing lid inserted in a manner forced into the sleeve or sleeve (6). This sleeve or cylindrical sleeve ^ (6) serves as a member to handle the applicator. This also serves as a cap designed, especially, to be screwed onto the neck (13) of a varnish bottle (11). The varnish carries the reference (12). Figures 1 to 1 illustrate various exemplary embodiments of an applicator, including a flexible rod. In this way, the Figure is shown by an applicator that includes a flexible rod (5), a first end (5a) which is attached to a first end (8) of an otmechón (2) of bristles (3). A second end (5b) of the rod is formed in the form of an assurance or fastening cover, designed to be forcedly inserted into the sleeve or sleeve (6), in order to secure it to the flexible rod. The rod is advantageously made of HDPE or LDPE (high density polyethylene or low density polyethylene) which includes a region (51) in the form of a flattened tongue, which gives the rod a defined flexibility and which extends virtually over the full length of the rod. The applicator of Figure Ib has substantially the same shape as that of Figure 1, with the exception that the rod (5) is cylindrical but includes a longitudinal groove (52), in order to ensure the flexibility of the dipstick. The Figure shows an applicator whose rod (5) is formed, in part, by two strips (53) arranged in the form of two twin propellers forming a twin start spiral. Figure Id shows an applicator whose rod (5) is formed, on the main part thereof, by a flat strip 54, which is shaped in the form of an "accordion" or includes corrugations. The Figure shows you, in enlarged view, the applicator shown in Figure 1, the rod (5) of which is cylindrical and includes a central region (55) of reduced cross section - the rod has a maximum cross section of approximately 4 to 20 mm2 and the region (55) has a cross section of about 0.2 to 1.2 mm2. The region (55) can extend over a length that falls between 2 and 20 mm. This region, when covered with varnish, constitutes a mini-deposit so that the tuft (2) is fed with a controlled flow of varnish. Furthermore, in this region, the drying of the varnish is diminished in comparison to a rod that does not include a reduced cross section. Figure lf shows an applicator according to a second embodiment, the rod (5) of which includes a region (56) formed, in part, by a steel wire, for example a portion of a piano wire having a diameter of approximately 0.3 mm. Figure lg shows an applicator according to a second embodiment, the rod (5) of which includes a region formed by a metallic spiral (57) having turns that touch or do not touch, such as a coil spring, which it has a wire diameter of approximately 0.3 mm and a turn diameter of approximately 3 mm. Figure lh shows, according to another variant fashion, an applicator whose rod (5) is cylindrical and includes a central region (55) of reduced cross section - the rod has a normal cross section of about 4.0 to 20 mm2, and the region (55) has a cross section of about 0.2 to 1.8 mm2. The smallest cross-sectional region is a chosen cross-section so that the S / s ratio falls between 3 and 100, with s being the smallest cross-section and S the largest cross-section. The application member (2) is a rope (21) in the form of a turn, provided with a velvety coating (30). This rope includes, for example, a core made of polyvinyl chloride elastomer, polyurethane elastomer or polyester elastomer, this core having a diameter of 0.1 to 3 mm. The entire surface of the rope is covered by a velvety coating (30), of conventional construction, for example made of nylon fibers having a diameter of about 2/100 mm and a chosen length of the range ranging from 0.1 to 1.5 mm. Figure li shows, according to another variant modality, an applicator whose rod (5) is cylindrical and includes a central region '55) of reduced transverse section, as in Figure lh. The application member (2) is a bundle of fibers (22) that has received a velvety coating (30). The fibers are, for example, made of nylon which has a core having a diameter of about 4/100 to 60/100 of mm, and includes a velvety coating of the same type as that of Figure 1h. Figure 1 shows, according to another variant embodiment, an applicator substantially similar to that of the preceding figures, with the exception that the application member is a spatula (23) of flattened shape, made of a flexible or semi-flexible thermoplastic material , for example a vinyl chloride stastomer or polyurethane elastomer, which includes a velvety coating of the same type as that of the application member shown in Figure lh. Figure lk shows, according to another variant embodiment, an applicator substantially similar to that of the preceding Figure, with the exception that the application member is a spatula (24) made of foam, for example a polyurethane foam, of polyether or latex, with open cells. The application member (2), according to Figures 1 to 1, is fixed, advantageously by welding or bonding with adhesive, to the free end (5a) of the rod (5). This can be mounted on the rod shown in Figures la a la lg. The tuft (2) of the applicators in the form of a brush, according to Figures 1 to 1, according to the first variant embodiment, can be obtained from a bunch of substantially parallel, folded bristles (3) in two, approximately half its length. The tuft (2) is fixed to the free end (5a) of the rod (5) by coupling the folded part (8) of the tuft of bristles, as shown in Figure 2, hermetically in a housing (9) formed through a blind hole that opens at the end of the rod (5). In general, the tuft (2) is produced by placing the intermediate region of the bunch of bristles on the entrance of the housing (9) of the rod (5). A staple (10) is coupled around the region located substantially midway along the bundle of bristles, and is pressed just inside the housing (9), thereby causing the bristles (3) to fold, leading the bristles against the edge of the housing (9). During this operation, the staple (10) is bent so that it squeezes the bristles and is forcedly engaged within the rod (5). The staple (10) is advantageously made of a U-bend wire, the cross section of which can be circular, rectangular, flat or square. The diameter or the largest side of the cross section of the wire advantageously falls in the range of 0.2 mm to 1.5 mm. The end region of the housing (9), as can be seen in Figure 2, can be a cylinder of revolution with an end region in the form of a cone of revolution, truncated, flared, thus favoring the separation of the bristles (3). The lock (2) of the brush (1), embedded in such a housing, has a truncated cone shape with a substantially circular base (see Figure 15). The conditions under which the sows (3) are embedded in the housing (9), as can be seen in Figure 3, they play a decisive role in the creation of the interstices (i). In fact, this gap (i) is a key factor in determining the amount of product collected, and therefore the degree of autonomy of the brush. In this way, capillary reserves of the product to be applied are created, which make it possible for the load of the product to be varied depending on its viscosity. As can be seen in Figures 4 to 9, the cross sections of the bristles (3) are inscribed in a circle (¿) of diameter that falls between 8/100 and 30/100 of mm - preferably the cross section is chosen of the range from 11/100 to 25/100 of mm. The cross sections of the bristles (3) can have variable shapes - these can be solid circular (3a) as illustrated in Figure 4, hollow circles (3b) as illustrated in Figure 5, in the form of C (3e) as can be seen in Figure 6, in the form of an L or a V (3d) as can be seen in Figure 7; these can have a flat shape (3c) as can be seen in Figure 8, or they can be polygonal, particularly square or cruciform (3f), as can be seen in Figure 9. According to the modality of the Figure 10, the bristles (3g) may not be straight but have, at least over part of their length, slight corrugations (7). These bristles, of the same type or of a mixture of various types (see Figures 4 to 9) of these bristles, are in the form of a tuft (2). According to Figure 11, the end of the tuft (2) is flat, substantially rectilinear. According to Figure 12, the ends (4) of the bristles (3) together have a rounded configuration obtained, for example, by trimming. According to the embodiment according to Figure 13, the ends (4) of the bristles (3) have been cut so that they are inclined.

The brush (1) in its tuft (2) can have various shapes in cross section; according to Figure 14, the cross section (SI) of the lock is flat, substantially rectangular in shape. According to Figure 15, the cross section (S2) of the lock is circular. In these cases, the brush can also have a cross section (S3) in the form of a rounded tile, as can be seen in Figure 16, the applicator being better fitted to the shape of the nail. Figure 17 shows an applicator with a flexible rod, according to the invention, during the application of a varnish. It can be seen that the tuft (2) of bristles and the flexible part (55) of the rod (5) form a virtually constant curve, substantially an arc of a circle, so that the tuft (2) is in contact with the nail (N), substantially tangentially. When a cylindrical brush according to the first variant of the present invention is produced, the diameter of the tuft (2) of the bristles (3) generally falls within the range of 0.5 to 6 mm; by virtue of the use of a flexible rod as previously described, an applicator is obtained which, during the application, pulls the varnish instead of pushing it, as in a conventional applicator.

The applicator having the characteristics that have been just described, is particularly well suited for the application of a nail varnish, a liquid make-up or a hair dye, especially a varnish with a high viscosity. This varnish may have a composition that may or may not include toluene or formalin; this varnish may also include a solvent system comprising water and / or alcohols. The deposited varnish layer is very uniform, coarse, deposited correctly and has, after drying, improved adhesion properties. The surface has a lustrous appearance. The varnish can be deposited in a single turn or possibly in two turns, it being possible for the second layer to be deposited on the first, before it has dried. No streaks are formed.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates.

Having described the invention as above, property is claimed as contained in the following:
