Description

The invention relates to an applicator for a cosmetic product, in particular for mascara, a method for manufacturing such an applicator and a receptacle capable of containing such an applicator.

Mascara applicators can be injection molded from plastic, they are then commonly called “plastic brushes”. They can also be obtained from fibrous elements held between the longitudinal parts of a twisted spindle; they are then commonly called “fiber brushes”. Mascara applicators have a core, or central part, and pins extending radially around said core. The ends of said pins usually form envelopes in a direction of main longitudinal extension of said brush. The bristles of fiber brushes are commonly called “the fibers”.

The plastic brushes of the prior art have distributions of pins around the core which allow the production of complex envelopes favoring makeup. Concerning fiber brushes, such characteristics seem more difficult to obtain, unless fiber cutting operations are required along trajectories that are difficult to implement. The document FR2991560 discloses for example a fiber brush having at least two notches and a zone devoid of notches at the distal end of said applicator.

The documents US2011048448 discloses a cosmetic applicator with distinct application zones whose bristles may have different colors or diameters.

The invention proposes to produce an applicator provided with fibers which, through their ends, form a complex envelope, having advantageous characteristics in terms of makeup, while remaining relatively simple to obtain.

Thus, the invention relates to an applicator for a cosmetic product, in particular for mascara, as defined in claim 1. Particular embodiments are defined in the dependent claims. An applicator according to the invention comprises a core and a plurality of fibers projecting from said core, said core extending in a main longitudinal direction of extension, called the main direction, said fibers being distributed along the core , over a substantial part of its length between a proximal end and a distal end opposite each other along said main direction, said fibers forming an envelope with their free ends.

According to the invention, said envelope extends along said main direction by presenting at least two longitudinal notches, said notches having, in a plane transverse to said main direction, a trapezoid shape, said trapezoid being in particular isosceles, defining thus notches with two side edges and a bottom, said side edges forming obtuse angles with said bottom, said bottom being flat, the fibers forming the bottom of the notches having a radial extension from said core, called first radial extension, said notches extending over part of said main direction so as to define, at the level of the distal end of said applicator, a zone devoid of notches, defined by fibers whose radial extension from the core is less or equal to said first radial extension.

The invention therefore proposes an applicator which has notches around the perimeter of the envelope formed by the fibers which compose it. This has the advantage of training a user's eyelashes thanks to an effect of their hooking by the areas located between the notches. Thus, a user's eyelashes are lengthened, curled and/or combed effectively. Furthermore, the notches serve as a reservoir for the cosmetic product and the user's eyelashes are therefore properly loaded.

The applicator of the invention has the additional advantage of presenting, at the end, at its distal end, a zone used for precision makeup, in particular because the fibers there have a low radial extension.

The use of a fiber brush also allows a greater density of fibers than with the pins of plastic brushes.

As illustrated in the figures, the invention relates to an applicator 10 for a cosmetic product, in particular for mascara. This applicator 10 is particularly suitable for applying makeup to a user's eyelashes and/or eyebrows. It comprises a core 11 and a plurality of fibers projecting from said core 11. It is in particular a core formed of twisted strands, in particular two twisted strands, between which the fibers are held. Said strands are, for example, metallic. This applicator 10 advantageously forms a fiber brush.

Said core 11 extends in a main longitudinal direction of extension, called main direction along said main direction X. Substantial part means most of the length of the core 11.

The core 11 consists of a twisted rod and its proximal end 12 is extended by a portion of the rod devoid of fibers 15, also called sleeve 15. This sleeve 15 is advantageously intended for assembling said brush 10 with a rod, itself linked to a means allowing the assembly to be manipulated by the user, for example a cap (assembly not illustrated here).

Said fibers form an envelope E1-E3 with their free ends.

According to the invention, said envelope E1-E3 extends along said main direction X, presenting at least two longitudinal notches 21-23.

Here, the envelope E1 of the figure 1 , illustrating a first embodiment, has an extremum along the main direction envelope E1 can therefore be described as an ogive-shaped envelope.

The E2 envelope of the Figure 3 is curved along the main direction X, which gives it a substantially convex overall profile (second embodiment).

The E3 envelope of the figure 5 , illustrating a third embodiment, is close to that of the envelope E1 of the figure 1 .

It should be noted that the invention is not limited to the examples of envelopes E1-E3 illustrated here and that all other forms of envelope could be considered, without departing from the scope of the invention.

According to the invention, said notches 21-23 have, in a plane transverse to said main direction X, a trapezoid shape. By “longitudinal notches” is meant notches 21-23 which follow the main direction X. In other words, notches 21-23 which have longitudinal extensions parallel to said main direction », a trapezoid open outwards.

Furthermore, as can be seen in the figures 2 , 4 And 6 , said trapezoid is for example isosceles. In other words, the notches 21-23 have two side edges and a bottom, said side edges forming obtuse angles a2 with said bottom; in other words, angles a2 greater than 90° angle. Said obtuse angles a2 are inside the trapezoid; they are notably defined between the sides of the trapezoid and the smaller vertex of said trapezoid.

The side edges and the bottom are formed by the free ends of the fibers.

Between the notches 21-23, the free ends of the fibers define a surface S advantageously ensuring combing of the eyelashes. This surface S connects a side edge of a notch with a side edge of an adjacent notch. In cross section, this surface S is curved (see figures 2 , 4 And 6 ).

Said notches 21-23 are therefore comparable to trenches made on the surface of a frustoconical shape. Said trenches are provided with a bottom, or flat base, and side surfaces, or side edges.

Here, said bottom is flat and the fibers forming said bottom have a radial extension e21-e23, from said core 11 which will be called first radial extension e21-e23 subsequently.

Said notches 21-23 extend, moreover, over a part of said main direction fibers whose radial extension e14, e14' from the core 11 is less than or equal to said first radial extension e21-e23.

The zone 14, 14' without a notch is advantageously intended for precise makeup, for example parts that are difficult to access for the user. Said zone 14, 14' will here be called end piece 14, 14'. The fibers forming it have a radial extension less than, or equal to, the radial extension e21-e23 of the other fibers forming the brush 10; they are therefore more rigid.

This reinforces the function of the 14, 14' tip dedicated to fine and detailed makeup.

In addition, the end piece 14, 14' may be formed by fibers of a first type, while the rest of the envelope E1-E3 will be formed by fibers of a second type. By “fiber type” we mean fibers of different nature, particularly in terms of diameter, material, shape, hollow or solid.

For example, the fibers of the first and second illustrated embodiments - see figures 1 to 4 - will be solid fibers at the level of the end piece 14, with a diameter of around 0.178mm (7mils), while those forming the rest of the envelope E1-E2 will be hollow fibers, with a diameter of the order of 0.154mm (6mils).

The fibers used in the case of the third embodiment - see figures 5 and 6 - will be solid fibers with a diameter of around 0.127mm (5mils); here, only one type of fiber will be used for the E3 envelope and the 14' end piece.

These examples can advantageously be combined.

This makes it possible to provide different makeup effects, for the same brush, by varying the types of fibers along said main direction X.

In addition, the tip 14, 14' will prevent the presence of residue of cosmetic product at the end of the brush 10. In fact, the tip 14, 14' will capture the cosmetic product, particularly in the case of mascara, rather than letting it clump at the end of the brush 10.

.Said envelope E1-E3 will extend over a length, called the envelope length and denoted L. Said notches 21-23 will extend over a length, called the length of notches and marked l , said two lengths L and l being linked by the formula: $0.5\le \raisebox{1ex}{$L$}\!\left/ \!\raisebox{-1ex}{$L$}\right.\le 0.9$

.

For example, said length L will be of the order of 28mm, more precisely of the order of 27.7mm.

Said length l could be between 10 and 18mm.

In addition, the end piece 14 will have a length, marked t on the figures 1 to 4 , which will be of the order of 6mm - case of the first two embodiments. Indeed, in these two cases, the end piece 14 is clearly defined by fibers of a different type from those used for the rest of the envelope E1-E3.

In the case of the third embodiment, the tip 14' is rather defined from the place where the notches cease, due to the reduction in the radial extension of the fibers towards the distal end 13. The reduction in the radial extension of the fibers is due, here, to the pointed shape of the envelope E3.

The 14' end piece, on the Figure 5 , will have a length t' greater than one or a few millimeters compared to the end pieces 14 of the first two embodiments.

The end piece 14, 14' is advantageously designed to be quite substantial , particularly in terms of longitudinal extension along the main direction a tangible existence to this end piece 14, 14', by its significant length.

It should be noted that said notches 21-23 will have substantially the same cross section with respect to said main direction X, at all points of the part of said main direction X along which they extend. This means that, although the dimensions of this trapezoid evolve along said main direction X, said trapezoid remains substantially isosceles at all points of said notch 21-23.

Moreover, as is visible on the figures 2 , 4 And 6 , the lateral edges of said notches 21-23, made by the particularly isosceles sides of said trapezoids, form a substantially right angle a1 between them.

It is also visible on these figures 2 , 4 And 6 that the top of said trapezoids, forming the bottoms of said notches 21-23, has a length f21-f23 substantially equal to 2.5mm. This value may vary between 1.5 and 3.5 mm without departing from the scope of the invention.

The notches 21-23 thus dimensioned allow, advantageously, to effectively participate in the cosmetic product loading function of the brush 10 of the invention.

In addition, said envelope E1-E3 will present, in particular at the location where it has notches 21-23, a section in a plane transverse to said main direction X which has axial symmetry with respect to an axis perpendicular to said direction main X, said axis being contained in said transverse plane. This axis is marked Y on the figures 2 , 4 And 6 .

In the case of the first and second embodiments, said envelope E1, E2 has three notches 21, 22. Said notches 21, 22 will be spaced regularly around said main direction with an angular space substantially equal to 120° angle. This has the advantage of creating reservoirs for cosmetic products - the notches 21, 22 - on the periphery of said envelope E1, E2, said reservoirs being regularly distributed around the core 11.

In the case of the third embodiment, the envelope E3 will have four notches 23, said notches 23 being spaced regularly around said main direction with an angular space substantially equal to 90° angle. This has the same advantage of regular distribution of reservoirs for cosmetic products on the periphery of the E3 envelope.

This number of 3 or 4 reservoirs, or notches 21-23, is not limiting and a different number of notches 21-23 can be provided without departing from the scope of the invention. These notches 21-23 could be two in number, diametrically opposed on either side of the core 11, or even included in 5 and 8 notches, regularly distributed around the core 11, this without leaving the framework of the 'invention.

It should be noted that said notches 21-23 are made hollow relative to the surface of the envelopes E1-E3, with a flat bottom. It should also be noted that the fibers with the highest radial extensions form the majority of the brush 10 and that the notches 21-23 are punctually distributed on the surface of the envelopes E1-E3 which they form.

The external diameter DE1-DE3 of said envelopes E1-E3 will, for example, be between 7.5 and 11mm, in particular of the order of 9.3mm, or even 9.5mm.

The radial extension e21-e23 of the fibers forming the bottom of said notches 21-23 will be between 3 and 4mm, more particularly of the order of 3.3mm. As a reminder, the distance between the main direction X and the free end of the measured fibers is called “radial extension”.

On the other hand, the diameter d14, d14' of the end piece 14, 14' may vary between 4 and 6mm. For example, the diameter d14, d14' will be around 4.9mm.

The invention also relates to a method for manufacturing an applicator for a cosmetic product, in particular mascara, for example that which has just been described.

This method first comprises a step of positioning a plurality of fibers between longitudinal parts of a spindle (not shown). The fibers are distributed in such a way that said longitudinal parts pass substantially in the middle of each of said fibers.

Said fibers may be of different types, as mentioned above, in particular with the aim of defining a particular tip 14 (see first and second embodiments).

The next step of said method is a first step of twisting said spindle to form a twisted spindle having fibers extending radially around it. The ends of said fibers then form an envelope E1-E3 extending in a direction of longitudinal extension around said pin. The fibers are distributed in the form of fiber turns due to the twisting of the spindle.

Said twisting step can be replaced by a first twisting step leading to a cylindrical envelope, followed by a first cutting step to form said envelopes E1-E3, having an extremum or having a curved profile, in particular between said proximal ends and distal.

The following step is a step of cutting the fibers so that said envelope E1-E3 has at least two longitudinal notches 21-23, said notches 21-23 having, in a plane transverse to said main direction X, a trapezoid shape, said trapezoid being in particular isosceles, thus defining notches 21-23 with two side edges and a bottom, said side edges forming obtuse angles a2 with said bottom, said bottom being flat, the fibers forming the bottom of the notches 21-23 having a radial extension from said core, called first radial extension d21-d23, said notches 21-23 extending over part of said main direction applicator 10, a zone without a notch, defined by fibers whose radial extension e14, e14' from the core 11 is less than or equal to said first radial extension e21-e23.

It should be noted that said twisted pin is kept straight.

It could also, in an embodiment not illustrated, be curved after said step of cutting the fibers to form said notches 21-23.

It should be noted that the invention also relates to a receptacle for a cosmetic product (not illustrated), capable of containing a brush as described above.

It should also be noted that the embodiments illustrated in figures 1 to 6 can advantageously be combined in order to combine makeup effects, or even with the aim of obtaining new ones.
