Abstract
Description
[Technical field]
[0001] The present invention relates to a brush for applying a cosmetic composition, in particular a make-up or care product, such as mascara, to the eyelashes or eyebrows, and to a packaging and application device comprising such a brush. [Background technology]
[0002] Mascara applicators are known in which the brush inside comprises a core formed by two metal wire arms intertwined to grip the bristles. The bristles used are generally of the same length, so that when the arms are intertwined the brush has an envelope surface in the shape of a cylinder of revolution. Such a shape has limited effectiveness in terms of depositing and separating the product on the eyelashes.
[0003] Therefore, efforts have been made to make the envelope shape more complex in order to create zones on the brush where the product is more heavily loaded after wiping, allowing it to be properly placed on the lashes, and zones where the product is less loaded or barely loaded and can be used to comb and separate the lashes. There are many factors involved, so a lot of testing is required to find the shape that gives the best makeup results.
[0004] A similar problem occurs with brushes formed by injection molding.
[0005] EP1236419 discloses a brush with a curved core and a distal end of the core on the concave side of the core, offset from the longitudinal axis of the handle. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] European Patent Application Publication No. 1236419 Summary of the Invention [Problem to be solved by the invention]
[0007] There is a need to make it easier to apply makeup along the upper and lower lash rows.
[0008] There is also a need for improved brushes, particularly to benefit from brushes that are able to satisfactorily apply makeup to the eyelashes or eyebrows by providing good product loading and good combing ability. [Means for solving the problem]
[0009] Applicator According to one of its aspects, the present invention relates to an applicator for applying a cosmetic composition to human keratinous fibres, in particular to the eyelashes or eyebrows, said applicator comprising: - a handle having at least a straight portion extending along a straight axis; a brush at one end of a handle, said brush comprising: a curved core having a distal end and defining a convex side and an opposite concave side, the distal end of the core being offset from a linear axis of the shank to the convex side of the core; A coating member supported by a core; Equipped with.
[0010] "Convex" means convex outward. "The distal end of the core is offset from the linear axis of the handle to the convex side of the core" means that the vector GD defined by the orthogonal projection G of the distal end of the core onto the linear axis of the handle and the distal end D of the core, pointing from G to D, has substantially the same sense as the vector H perpendicular to the linear axis of the handle, pointing from the concave side to the convex side of the longitudinal axis of the core. In other words, if the core needs to be tilted from an initial configuration in which the distal end is aligned with the linear longitudinal axis of the handle to a final configuration with a desired offset, the tilting is accomplished by deforming the core in a direction from the inner arc of the core to the outer arc of the core.
[0011] As a result of the present invention, the performance of the brush is improved in terms of depositing product on the eyelashes while achieving satisfactory combing. The present invention makes available a brush that provides a product reservoir in the concave portion and a combing zone with less product in the convex portion. The offset may result in more interference between the wiper member and the brush, resulting in less composition remaining on the convex side of the brush near the distal end of the brush. This increased interference may allow the use of a more viscous composition, which improves makeup performance. The present invention may make it easier to apply the composition and avoid the formation of lumps during application. The present invention may also make it easier to apply makeup to the eyelashes at the corners of the eyes.
[0012] Preferably, the handle is straight along its entire length. This allows the applicator to use a conventional straight handle, which is easy to manufacture and assemble with the brush. However, in some variations, the handle has a main straight section, which preferably extends over the majority of its length, and a distal section that is at an angle to the straight section of the handle, such that the orientation of the distal section of the handle provides, or at least partially contributes to, the desired offset to the distal end of the core.
[0013] Preferably, the core is a stranded wire core, but the invention also applies to injection molded brushes. When the core is a stranded wire core, the application members are conventionally bristles gripped between the turns of the twisted core strands.
[0014] Preferably, the core is non-linear along its entire length from the shank to its distal end. However, in some alternative embodiments, the core may have at least one portion that is linear but maintain an overall curved shape. Preferably, the curved core is of constant curvature, although the core may have a radius of curvature that varies along the bristle-retaining portion.
[0015] The distance from the linear axis of the handle to the curved core may reach a maximum value at a position between the proximal and distal ends of the curved core, preferably between one-quarter and three-quarters of the length of the curved core between these proximal and distal ends, more preferably between one-third and two-thirds of said length.
[0016] Preferably, the core extends along a longitudinal axis of a substantially constant radius of curvature from the stem to the distal end of the core, such radius of curvature may be greater than or equal to 34 mm and less than or equal to 47 mm, and is preferably about 40 mm.
[0017] Preferably, the longitudinal axis of the core extends in a plane, such plane being preferably the midplane plane of symmetry of the envelope surface of the brush defined by the free ends of the application members.
[0018] Preferably, the applicator members define an envelope surface of non-circular cross section along at least part of their length.The applicator members may be bristles or spikes extending around the core.
[0019] The envelope surface may define at least one facet of a flat cross section on the convex side of the core, i.e., on the outer arcuate surface of the brush. In some variations, the envelope surface defines at least one facet of a concave cross section on the convex side of the core. Such a concave cross section may form at least one flute extending along the brush on the convex side of the core, i.e., on the outer arcuate surface of the brush.
[0020] In some embodiments, the cross-section of the surface envelope of the brush has a number of straight line segments connected by circular arcs, the angular extension of which about the core may be relatively small, giving the cross-section of the brush a substantially triangular shape.
[0021] The cross section of the envelope may be a substantially triangular profile with an apex lying in a plane in which the longitudinal axis of the core extends.
[0022] The inclination angle between the linear axis of the straight portion of the shaft and the line connecting the distal end of the core to the distal end of the straight portion of the shaft is preferably 0.5 to 10°, better 0.6 to 8°, more preferably 0.7° to 5.7°, most preferably 2° to 4.5°, for example about 3.2°.
[0023] Preferably, the offset is greater than 0.5 mm. Preferably, the offset is greater than 2.5 mm. Advantageously, the offset remains small enough to allow the brush to be inserted into a container containing the composition to be applied and provided with a wiper member defining a wiping opening, without the distal end of the core coming into contact with the wiper member, with the insertion movement of the brush being a linear displacement along the linear axis of the handle. This allows for automatic attachment of the applicator to the container with a simple mechanism. The offset may not exceed, and is preferably close to, half the diameter of the wiping opening. If D is the diameter of the wiping opening, the offset f may be between 0.8D / 2 and 1.2D / 2, better between 0.9D / 2 and 1.1D / 2, even better between 0.8D / 2 and D / 2, or more preferably between 0.9D / 2 and D / 2.
[0024] The envelope surface may include a frusto-conical or leek-shaped distal portion having a cross-section that becomes smaller towards the distal end of the core. The frusto-conical or leek-shaped distal portion may extend over a length greater than one-quarter of the length L of the portion of the core that supports the applicator member and less than one-third of the length L of the portion of the core that supports the bristles.
[0025] At its opposite end from the brush, the handle may be fastened to a cap for closing the container.
[0026] Device According to another of its aspects, in combination with the above, the present invention further relates to a device for applying a cosmetic composition to keratinous fibers, preferably to eyelashes, said device comprising: - a container containing the composition, the container comprising a wiper member; an applicator according to the invention as defined above; Equipped with.
[0027] The wiping member is configured to remove excess product present on the handle and the brush, and comprises, for example, a lip made from an elastic material, the lip defining a wiping opening preferably having a circular cross section, the diameter of which corresponds substantially to the diameter of the handle.
[0028] The wiper member and brush may be configured such that when the applicator is withdrawn from the container along said linear axis, the application member on the convex side of the core, i.e. on the outer arcuate surface of the brush, contacts the wiper member at an axial location, measured along the curved longitudinal axis of the core, less than 3 mm from the proximal end of the brush. In some embodiments, the smaller this distance, the better, as this means that the outer arcuate surface of the brush contacts the wiper member earlier in the brush's passage past the wiper member, resulting in no clumps of composition on the outer arcuate surface of the brush near its proximal end.
[0029] Method for manufacturing a brush According to another of its aspects, in combination with the above, the present invention also relates to a method for manufacturing a brush for use in an applicator as defined above, comprising the steps of: - machining a stranded core brush having a straight core to form at least one flat or concave facet of an envelope surface defined by the free ends of the bristles, the core having a proximal portion for fastening to a handle and a bristle retaining portion; - deforming the core to impart to the bristle-holding portion a curved shape having a convex side and a concave side, the distal end of the core being offset from a longitudinal axis of the proximal portion of the core on the convex side; Includes.
[0030] The core can be deformed along a plane of curvature.
[0031] The flat or concave facets are preferably on the outer arcuate surface of the brush after curvature of the core.
[0032] The machining step may include forming at least one flat facet, or at least one facet with an envelope surface recess, along the length of the brush over the majority of its length.
[0033] The machining step may include forming three flat facets of the envelope surface to give the envelope surface a substantially triangular cross section with an apex at the bending surface of the core.
[0034] The machining step may include forming a frusto-conical head.
[0035] The facet or facets may be machined such that they intersect with the frusto-conical head.
[0036] The step of deforming the core may include imparting a certain curvature to the bristle-holding portion and then tilting the core at the junction of the bristle-holding portion and the proximal portion, or vice versa.
[0037] According to another of its aspects, the invention also relates to a method for manufacturing a brush for use in an applicator as defined above, comprising the step of injection moulding the core and the application member with at least one plastic material.
[0038] Make-up method A further aspect of the invention is a make-up method for making up human keratin fibres, comprising the step of applying a cosmetic composition to said fibres using an applicator as defined above. In such a method, a brush according to the invention is loaded with the cosmetic composition, which is then applied to the surface to be made up, in particular the eyelashes or eyebrows. During the movement of the brush through the wiper member, the brush may follow a translational movement along the linear axis of the handle. The brush may be used to make up the eyelashes at the edge of the eye, using a portion of the brush on the outer arc surface near the distal end of the core. Such a portion carries a small amount of composition due to the impact of the brush with the wiping member and is therefore effective in combing said eyelashes at the edge of the eye.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0041] In the following description, identical elements or elements having identical functions are designated by the same reference numerals, their description will not be repeated for each of the figures, and only the main differences between the embodiments will be noted.
[0042] The cosmetic device 1 shown in Fig. 1 comprises a container 2 containing a cosmetic composition P to be applied to the eyelashes or eyebrows and an applicator 3 which in this example can be removably fixed to the container 2. The composition P comprises, for example, one or more pigments, in particular iron oxide. The composition P is, for example, a mascara.
[0043] The applicator 3 comprises a handle 5 having a rectilinear longitudinal axis Y and provided at its distal end 7 with a brush 10 according to the invention and at its other end with a cap 11 for hermetically closing the container 2. The latter has a body provided at its upper part with a threaded neck 14 onto which the cap 11 can be screwed to close the container 2. In an alternative, the applicator may be fixed to the container in some other way.
[0044] The neck 14 may accommodate, for example as shown, a wiping member 20 which is inserted into the neck 14. This wiping member 20 comprises a wiper lip 21 defining a wiping opening having a diameter D adapted to the diameter of the handle 5, for example a diameter of 4.25 mm.
[0045] The brush 10 may be fixed in a conventional manner to a seat 8 (visible in FIG. 15) provided on the distal portion 6 of the handle 5, advantageously made from a thermoplastic material.
[0046] The brush 10 comprises a braided metal core 40 with a curved portion 43 carrying the bristles 41 and a straight proximal portion 44 visible in Figure 2, which is inserted into the above-mentioned seat 8 provided in the distal portion 6 of the handle 5. The core 40 may be made by braiding two strands of U-shaped metal wire, the bristles being tightened by winding the wire. The diameter of the metal wire may vary and is, for example, about 0.7 mm.
[0047] The free ends of the bristles 41 define an envelope surface E having a shape resulting from the trimming of the bristles 41 and the curvature imparted to the core 40 after trimming, as will be explained below.
[0048] The bristles 41 may be of any kind, with a circular cross section, or better still with a non-circular cross section, for example a C-shaped cross section.
[0049] The bristles may be made from any material, preferably a thermoplastic material such as polyamide.
[0050] The outer diameter of the bristles may vary, for example being about 13 / 100 mm.
[0051] To manufacture the brush 10, one may start with the unfinished brush shown in Figure 5, which has a straight core and an envelope with a cylindrical portion E1 and a frusto-conical head portion E2. The overall length L of the bristle-holding portion may be 20 to 35 mm, for example about 28 mm, and the length l of the frusto-conical portion E2 may be about 9 mm. The diameter d2 at the distal end of the frusto-conical portion may be about 4 mm, and the diameter d1 of the cylindrical portion of circular cross section may be about 7.5 mm, the invention not being limited to any particular values.
[0052] The bristles are then trimmed to form three flat facets 51, 52 and 53 as shown in FIGS.
[0053] Each of these facets extends the entire length of the cylindrical portion E1 and a portion of the frusto-conical head portion E2, as can be seen in FIG.
[0054] The angle h between facets 51 and 52 may be approximately 60°, as shown in FIG. 8, giving the brush cross section a generally triangular profile.
[0055] Facets 51, 52, and 53 are separated in cross section by a circular arc 55.
[0056] When the brush is trimmed, the bristle-retaining portion 43 of the core is permanently deformed to give the brush its final shape. The flat facets 51, 52, and 53 are transformed into arcuate shaped facets 151, 152, and 153, respectively, with facet 153 extending along the outer arc of the brush.
[0057] In the example shown, the radius of curvature R of the longitudinal axis X of the curved core portion 43 is constant and is about 40 mm. The longitudinal axis X of the curved portion 43 extends in the mid-plane M of the envelope surface E, which is a plane of symmetry.
[0058] The curved portion 43 has a convex side adjacent the outer arcuate surface of the brush, to the left of the core in FIG. 2, and a concave side to the right of the core in FIG.
[0059] In accordance with the present invention, the distal end 46 of the core 40 is offset from the longitudinal axis Y of the handle 5 by a non-zero distance f, such that the distal end 46 is offset to the convex side, i.e., to the left of the longitudinal axis Y in FIG. 2, which is the outer arcuate surface of the brush.
[0060] The angle w between a core connecting line Z, which connects the distal end of the handle and the distal end 46 of the core 40, which substantially coincides with the junction of portions 43 and 44 of the core 40, on the one hand, and the longitudinal axis Y, on the other hand, is approximately 3.2° in the illustrated example.
[0061] Due to the offset of the distal end 46 of the core relative to the longitudinal axis of the handle 5, wiping occurs more efficiently on the outer arcuate surface of the brush, as will be further explained below with reference to FIGS.
[0062] FIG. 9 shows the brush 10 as it reaches the wiper lip 21 during withdrawal of the applicator from the container.
[0063] As can be seen, the bristles of facet 153 that first contact wiper lip 21 have a relatively small abscissa x, for example 3 mm or less, measured along longitudinal axis X of curved portion 43 from the proximal end of origin x0.
[0064] Such contact early in the withdrawal ensures that facet 153 is efficiently wiped along substantially its entire length.
[0065] As the brush passes almost entirely over the wiper lip 21, as shown in FIG. 10, the edge of the wiping lip is relatively close to the curved portion of the core in region A of the outer arcuate surface near the distal end of the brush, providing a strong wiping action in this region A.
[0066] However, the offset f is preferably small enough so that when the applicator 3 is moved along the longitudinal axis Y to attach the applicator 3 to the container 2, the distal end of the core enters the wiping opening without contacting the wiper lip 21. This facilitates automatic attachment of the applicator 3 to the container 2.
[0067] In alternative embodiments, the brush has other cross-sectional shapes.
[0068] For example, as shown in FIG. 11, the brush may simply exhibit one facet 153 on the outer arcuate surface of the brush, of the envelope surface.
[0069] The facets 153 may be flat in cross section, as shown in FIG. 11, or may be concave, as illustrated in FIGS. 12-14.
[0070] In FIG. 12, facet 153 has a C-shaped cross section, in FIG. 13 it has a V-shaped cross section, and in FIG. 14 it has a U-shaped cross section, although other configurations of longitudinal cutouts are contemplated.
[0071] The offset of the distal end of the core according to the present invention can enable wiping of the bottom of the notches, at least in the area near the distal end of the brush, so that the wiped brush has less composition remaining on its outer arcuate surface and is better suited to combing the eyelashes.
[0072] In the variant shown in FIG. 16, the handle 5 has a straight main portion 5a which extends to the cap 11 and a relatively short straight distal portion 5b which extends along an axis K which forms an angle g with the axis Y of the main portion 5a.
[0073] The core 40 is fixed to the seat 8 provided in the distal portion 5b, with the curved portion 43 extending in the same plane as the plane defined by the axes Y and K. The convex side of the curved core 43 faces towards the left in Figure 16, with the axis K lying below the main portion 5a.
[0074] In the embodiment of Figure 15, the core 40 is angled out from the handle 5 to help provide the desired offset of the distal end of the core. In the embodiment of Figure 16, by angled distal portion 5b of the handle, the core 40 may not need to be angled out from the handle as shown.
[0075] The present invention also applies to injection molded brushes.
[0076] FIG. 17 shows an example of a brush 10 made by injection molding of one or more plastic materials, such as thermoplastic elastomers, with applicator members 41, such as spikes, made integral with the core 40, of the same or different material.
[0077] The invention is not limited to the described exemplary embodiments, the features of which may be combined with one another in alternative forms not shown. [Explanation of symbols]
