Definitions
- the invention relates to the field of applicators for fluid or pasty products, more particularly on keratinous fibers, typically applicators of cosmetic products such as mascaras.
- applicators intended to cooperate with a reservoir container for the mascara, typically comprise: a) a cap for closing said container and serving as a gripping means of said applicator, b) an axial rod, c) and a means for application.
- Said application means or applicator can be constituted by a brush, said rod being secured to said cap at one of its ends, and said brush at the other of its ends, said brush comprising a metal twist solidarisant a plurality of bristles or fibers.
- No. 4,927,281 discloses a brush comprising fibers provided with grooves or patent document EP 1 459 647, a brush comprising deformed bristles extending non-radially.
- the gains in charging power are very limited and the cost of the fibers high, because of their specificity.
- EP 1 518 477 and US 4 586 520 disclose brushes having axial alternation of portions with long fibers and portions with short fibers, the short fiber portions acting as mascara tanks and fiber portions. long as combs. Obvious problems prevent the manufacture of such brushes because of the difficulty to obtain automatically this axial alternation of long fibers and short fibers prior to the winding of the metal twist.
- Patent documents FR 2793 121, WO 2001 41 599, US are also known.
- brush applicators for mascara having recesses formed by ablation of portions of the brushes fibers of standard type, said recesses making it possible to retain a significant amount of mascara by seen to deposit it in one application.
- This ablation operation for example by mowing or laser cutting, is complex to implement, causes a decrease in the painting power of the brush due to the decrease in the number of hairs and weakens the behavior of the remaining hairs, resulting in therefore a reduction in the service life of
- Another object of the invention is to provide such an applicator that can be obtained from a standard type of brush without ablation of fibers.
- Yet another object of the invention is to provide a method for the manufacture of an applicator for depositing a large amount of mascara that is both simple, inexpensive, fast and reliable. Such a process will allow more particularly obtaining such an applicator without ablation of fibers from a brush of the standard type.
- the subject of the invention is a cosmetic product applicator comprising fibers trapped between two twisted branches extending in an axial direction and defining turns, characterized in that at least one of said turns is a spiral which is not circular.
- the implantation of the fibers is then organized so as to allow the brush to retain a significant amount of mascara. Indeed, such a brush has recesses devoid of fibers due to the shape of the twisted branches.
- the applicator may further comprise the following features: the turns are not circular over at least one axial portion of the applicator;
- non-circular coil or turns describe non-circular ellipses
- non-circular ellipses have a ratio of long axis length to minor axis greater than 1.1;
- the invention also extends to a device for packaging and applying a product intended to be applied to the eyelashes or the eyebrows, comprising a container containing the product to be applied and comprising an applicator as defined above. above.
- the invention also extends to a method of manufacturing a brush, characterized in that it comprises the steps of: - taking a brush having bristles trapped between two twisted branches extending in an axial direction; and applying a radial pressure on said twisted branches.
- the radial pressure is preferably applied by clamping said twisted branches between n jaws of a press, n being between 2 and 6.
- the jaws are preferably stopped at the end of the stroke by a calibration wedge.

- FIGS. 1 and 2 respectively show a brush 1 of the standard type and a brush 101 according to the invention in view from below.
- the standard brush 1 consists of a twisted wire 2 trapping fibers 3.
- the fibers of such a standard brush 1 are evenly distributed all around a central axis A (also designated by axial direction). . More particularly, the fibers are helically wound around said axis A.
- the brush 101 according to the invention comprises a distribution of the fibers 103 constituting it around a central axis A which is different from the standard brush 1 and recalling known brushes for example from FR 2 791 121 obtained from a brush of standard type by ablation of the fibers on one or more angular sectors around the central axis.
- the fibers 103 of the brush 101 are not uniformly distributed all around the axis A.
- the fibers 103 of the brush 101 are distributed over two angular portions 104a, 104b about the axis A, these angular portions 104a. , 104b being separated by angular portions 105a, 105b devoid of fibers.
- the angular portions 105a, 105b devoid of fibers are recesses that can gorge on mascara.
- the brush 101 according to the invention comes more particularly from a deformation of a brush of the standard type, and more particularly from a deformation of the twisted branches or core, so as to reorganize the implantation of the fibers. This reorganization does not result in ablation of the fibers.
- Such a brush 101 according to the invention can be obtained by using the method according to the invention described hereinafter.
- a device for producing brushes is provided with a deformable wire, more particularly a standard wire of circular section, and with fibers, for example of polyamide or other synthetic or natural materials, hollow or solid, or a mixture of these fibers.
- the manufacturing device is typically a so-called standard device comprising means for cutting a portion of said wire, for folding said portion of wire 2 to form a hairpin-shaped pin. "U" with two limbs 6a, 6b substantially parallel and for placing between said branches 6a, 6b a regular ply 7 of fibers 3, as can be seen in FIG. 3.
- the pin forms more particularly a mediator of the ply 7.
- the device manufacturing device further comprises means for twisting the branches of the pin between which are trapped fibers.
- the twisted branches 6a, 6b each describe circular turns and the fibers 3 taken and held between two adjacent turns of the branches 6a, 6b form a double helical winding. continuous, the twisted branches and the helical winding of fibers extending in the same axial direction A.
- FIGs 5 and 6 show by way of example a press 10 respectively in a rest situation and in a compression situation.
- the press 10 comprises an anvil 11 provided with a crushing surface 12 and calibration wedges 13 of height h, and a firing pin 14.
- the standard type brush 1 is disposed flat on the crushing surface 12 between the Calibration wedges 13.
- the wire 2 of the brush 1 is schematically represented by a circle illustrating the winding in circular turns of the branches of the wire 2.
- the firing pin 14 is then lowered, bends the fibers 3 and deforms and crushes the branches of the wire 2 to abut against the calibration wedges 13, as shown in Figure 6.
- the brush 101 according to the invention by deformation of the brush 1 of the standard type.
- the branches of the wire 102 of the brush 101 according to the invention are wound in turns describing ellipses.
- the brush 101 is removed from the press 10, it is found that it has two angular sectors extending in the axial direction without fibers on either side of the wire 102.
- FIGS. 7a-c, 8a-c, 9a-c and 10a-c which illustrate different degrees of crushing of a brush, that is to say respectively a standard brush 1, an intermediate brush the, and two brushes 101 according to the invention.
- Figures Xa, Xb, Xc represent sectional views at different levels in the direction axial over a quarter of a turn.
- an orthogonal projection 20,20 ', 120 of the fibers 3,3', 103 of the brush 1,1'1O1 along the axial direction and an orthogonal projection 21,21 are represented in dotted lines.
- the orthogonal projections 120, 121 of the fibers 103 of the brushes 101 according to the invention show the formation of angular portions 104a, 104b provided with fibers and angular portions 105a, 105b devoid of fibers.
- the relative sizes of these portions 104/105 depend on the crushing applied. Thus, the more the branches 106a, 106b are crushed, the more the angular space 105a, 105b devoid of fibers will be extended.
- the orthogonal projections 21, 21 ', 121 of the profiles of the branches of the brush change due to the compression applied.
- the wire remains substantially in its crushed form after crushing in the press.
- the turns of the brush deform by crushing from a circular path to describe an elliptical or ovoid trajectory that is increasingly elongated as compression intensifies.
- the fibers are inserted regularly between the twisted branches so that two adjacent branches are slightly distant. Due to the compression, the distance between the adjacent branches in the direction of compression decreases to become zero on a portion of turns.
- the fibers caught between the branches where this distance decreases slide between the branches along the turn so that the fibers previously arranged regularly on a turn between two adjacent turns are trapped on a restricted portion of these adjacent turns where the distance to branch is sufficient. Consequently, the shape of the twisted core and the organization of the fibers is modified by the crushing.
- the fibers extending substantially radially perpendicular to the direction between the branches maintaining them, the angular portions 104a, 104b provided with fibers are on the sides or the compression has been exerted.
- the twisted branches define turns that are not circular, unlike brushes of standard type.
- turns are more particularly elliptical or ovoid (non-circular), as in the case where the brush according to the invention is obtained by compression between two jaws of a press.
- angular portions are devoid of fibers.
- the orthogonal projection of the profile of the branches in a plane normal to the axial direction describes a non-circular ellipse.
- the elliptical turns preferably have a major axis to minor axis ratio greater than 1.1 and even more preferably between 1.3 and 1.6.
- the deformations generated by crushing are also illustrated from another angle in FIGS. 11 and 12 which respectively represent a brush of standard type 1 and a brush according to the invention 101 in the plane of compression.
- FIG. 13 diagrammatically represents an applicator 30 comprising a brush 101 according to the invention, an axial rod 31 secured to an end 32 said to be smaller than said brush, typically via an axial free end of said brush 101, and a gripping means 33 secured to said axial rod 31 at an end 34 said upper.
- an applicator dispenser 35 comprising a mascara reservoir 36 having a threaded neck 37 which cooperates with said gripping means 33 forming a closure cap, and a wiper 38 integral with said neck 37.
- the applicator is screwed onto the dispenser, the fibers are immersed in the mascara.
- the brush 1 is too loaded with mascara. Its withdrawal from the reservoir puts the fibers in the middle of the lips of the wiper which removes the excess of produces and rids the product of the ends of the fibers so as to give them applicative and painting power.
- the brush 101 according to the invention can be loaded in product in the angular portions 105a, 105b devoid of fibers so that said brush according to the invention has a high charging power and allows to obtain a large volume at each application.
- hollow fibers 4 mils in diameter and 8.5 mm in length. - 50 fibers per turn
- a standard type brush having the first 4 characteristics mentioned above is manufactured.
- This brush is placed in a press between shims of 1.1 mm height calibration and is crushed said brush until the press reaches the end of stroke in abutment against the calibration wedges.
- the brush thus formed comprises two grooves symmetrical with respect to the central axis of the brush, said grooves extending in the axial direction and each having an angular sector devoid of fibers of about 90 °.
- the turns of this brush are elliptical and have a major axis (-1.6) on small axis (1.1) of about 1.45.
- Such a brush has a strong charging power and can be used with any type of mascara formula.
- calibration wedges makes it possible to obtain perfect reproducibility of the crushing applied to a brush of standard type and consequently a perfect reproducibility of the angle of opening of the angular portions without fibers. To play on this opening angle, simply play on the height h of the calibration wedges.
- Reproducible crushing of the brushes between the jaws of the press can also be achieved by measuring and controlling the pressure applied between the jaws.
- the crushing is carried out in a progressive manner, so as to allow the fibers to slide between the branches.
- the crush treatment may further be performed on only one or portions of the length of the brush.
- the brush then has an alternation of normal portions and portions with recesses. It is also possible to crush in a first direction on a portion of the brush and in a second direction perpendicular to said first direction on another portion of the brush.
- a brush according to the invention may also be manufactured by compression in a press comprising n jaws, these jaws compressing the brush radially simultaneously.
- a brush is then obtained comprising n grooves devoid of fibers extending axially and distributed around the axis.
- the number n of jaws is preferably less than 6. With 4 jaws compressing the brush at right angles two by two, a brush is obtained with four axial grooves offset 2 to 2 by 90 °.
- the invention naturally also extends to any brush obtained from the brush described above, for example by a subsequent step of additional rotation of the branches twisted around the axis as is known US5551456, and / or curvature of the soul as is known from EP0832580.
- the invention is obviously applicable to any type of brush, any size, with any type of son, and any type of bristles, normal, mixed or special profiles.
- the brush according to the invention can also be used to make a brush composite of the type described in EP 1 475 013 comprising an applicator element and a painting element.
- the brush according to the invention is easy, quick to manufacture and inexpensive because its manufacture only requires, from a brush of standard type, a crushing step, simple to implement.
- the product charging power is considerably increased compared to a standard type brush.
- the size of the angular portion free of fibers can be changed easily during the manufacturing process by simply changing the height of the calibration shims.
