Description

The present invention relates to an applicator for applying a cosmetic, makeup or care product to the eyelashes and / or the eyebrows, for example mascara. The invention also relates to devices comprising the applicator and a container containing the product to be applied.

The container is conventionally provided with a wiper member which wipes the rod of the applicator during its extraction from the container. The behavior of the applicator at the spinneret traverse depends on many factors such as the shape and nature of the sponge lip and the arrangement of the application elements on the spinnerette.

A compromise must be found regarding the amount of product that is left on the application site for make-up. A too vigorous spin of the application body makes it too little load and requires the user to frequently plunge the applicator into the container. Insufficient wringing leaves an excess of product difficult to manage and may lead to packets of product present on poorly separated eyelashes. Applications EP 1 070 465 and EP 1 070 466 disclose combs comprising a row of teeth arranged in a staggered manner, which overlap in part or totally. EP 2,084,987 discloses a brush comprising rows of pins arranged between rows of teeth of flattened cross-section, the pins alternating longitudinally with the teeth. There is a need to further improve the applicators for the application of a product, especially mascara, on the eyelashes and / or the eyebrows, in order to improve their performance, and more particularly to promote the creation on the application member more product-laden areas, which allow easy makeup and a fast and abundant load of eyelashes and / or eyebrows, while keeping a separation capacity of these satisfactory. The invention aims to meet this objective and its purpose, according fun of its aspects, an applicator for applying a cosmetic product, makeup or care, on the eyelashes and / or the eyebrows, comprising an applicator member comprising: a core extending along a longitudinal axis, and - pins carried by fame and arranged in groups of pins in longitudinal rows, applicator wherein the groups of pins are preferably regularly spaced along the longitudinal rows, and comprise each at least two pins, at least one longitudinal row of pins being axially offset relative to the consecutive longitudinal row so that at least one group of pins of the offset row occupies the same axial position as a free space of pins between two groups of pips in the consecutive row. The invention makes it possible to obtain, on the applicator member, in particular at the level of the free spaces of pins, at least one reservoir zone, little emptied of its contents during the extraction of the applicator, thus providing after spinning a surplus of produced throughout the length of the soul and on all sides. This surplus of product allows, from the first application, a significant and satisfactory load of product of the eyelashes and / or eyebrows. The applicator according to the invention makes it possible to separate the eyelashes and / or the eyebrows by avoiding the formation of packets, thanks to the axial offset present between the longitudinal rows of pins. It is possible to play during manufacture on the spacing between the pins of the groups of pins on the one hand, on the spacing between the groups of pins on the other hand, and on the axial offset between the longitudinal rows of pins, to adjust the level of charge in product of the applicator after spinning.

By "longitudinal axis of the soul" is meant the line joining the set of centroids of the cross sections of the soul. The longitudinal axis may be a central axis or an axis of symmetry for the core, especially when the core has a circular cross section or generally polygonal regular shape. The longitudinal axis of the core may be rectilinear or curved and may be contained in a plane, which may be a plane of symmetry for some or all cross sections of the soul. Preferably, the longitudinal axis of the core is rectilinear. By "pin" means an individualizable projecting element intended to come into engagement with the eyelashes and / or the eyebrows. By "longitudinal rows axially offset", it should be understood that the 30 pins of the same rank of these rows do not occupy the same position according to longitudinal faxe of the soul.

Core and Pins Each longitudinal row of pins is preferably axially offset relative to the consecutive longitudinal row. Each group of pins of at least one row preferably occupies the same axial position as the free space of pins between two groups of pins of the consecutive row; better, each group of pins of the soul occupies the same axial position as a free space of pins between two groups of pins of consecutive rows. The pins of the same rank of one longitudinal row on two can all occupy the same axial position along the longitudinal fax of the fame.

The spacing between the consecutive groups of pins is preferably constant within at least one longitudinal row, better within each longitudinal row. In a variant, the spacing between the consecutive groups of pins is variable, within at least one longitudinal row and / or one row to another. Within a longitudinal row, the spacing between two consecutive groups of spikes, measured at the base of the core, between the outer flanks of the last spike of the first group and the first spike of the second group, along the the row containing the groups may be between 0.3 mm and 2.5 mm, better between 0.45 mm and 1.5 mm. The axial offset between a longitudinal row of pins and the consecutive longitudinal row may be greater than or equal to the length of a group of pins of said consecutive row. By "length of a group of pins" is to be understood the sum of the width of the pins of the group and the spacing between said pins. Preferably, the pins are not superimposed when the applicator is viewed sideways in a direction perpendicular to the longitudinal axis of the core. The spacing between the pins of a group is preferably the same for all groups. In a variant, the distance between the pins of a group differs from one group of pins to another, within a longitudinal row and / or from one longitudinal row to another. This spacing, measured along the longitudinal axis of the row containing the group, between the bases of the pins facing each other may be between 0.05 mm and 2.5 mm, better still between 0.4 mm and 1 mm. , 3 mm. All groups of spikes advantageously comprise the same number of spikes. In a variant, the number of pins differs from one group of pins to another, within a longitudinal row and / or from one longitudinal row to the other.

The groups of spikes may comprise two or more spikes, for example three spikes or four spikes. The number of spikes per longitudinal row can be between 10 and 48. The implantation of the spikes can be such that the angular displacement around the longitudinal facet faxe, between the spikes of two consecutive crowns of spikes, in particular both crowns. of pins, or not, being preferably equal to half of the angular pitch fi between two consecutive pins of the same ring. The core advantageously has an alternation of two consecutive rings of pins not shifted between them, then two consecutive rings of pins offset from the first two rings and not offset between them. By "ring of pins", it is necessary to understand a row in the circumferential direction formed by pins occupying the same axial position on the longitudinal fax of fame. At least one longitudinal row may comprise an isolated pin at the proximal end of the core, better a longitudinal row in two comprises such a pin. A single crown of pins is thus advantageously present at the proximal end of the fame. Within at least one group, the spikes are advantageously of the same height, better within each group. In a variant, the height of the pins in the same group varies.

Preferably, the height of the pins varies, for example in a monotonous manner, as it moves along the longitudinal fax of the fame. Within a longitudinal row, the height of the pins preferably decreases towards the distal end of the core, in particular over at least half the apparent length of the applicator member. In a variant, the height of the pins is constant along longitudinal faxe of the core. The height of the pins may be between 0.15 mm and 4.5 mm, better between 0.3 mm and 3 mm. By "height of a pin" is meant the distance measured along the length of the pin elongation between its free end and the base of the pin by which it is connected to the core. By "axis of elongation of the pin" is meant an axis that passes through the centroids of the cross sections of the pin. The pins may have a width of between 0.1 mm and 1 mm, more preferably between 0.35 mm and 0.65 mm. By "width of a pin" is meant the largest transverse dimension of the pin, in section, according to longitudinal faxe of the soul.

The pins may have a thickness of between 0.1 mm and 0.85 mm, more preferably between 0.3 mm and 0.75 mm. By "thickness of a pin" is meant the largest transverse dimension of the pin, in section, perpendicular to the axis of elongation of the pin and longitudinal fax of the soul.

The pins of at least one group are advantageously of the same shape, better all the pins of a longitudinal row are of the same shape, even better all the pins of the applicator member are of the same shape. In a variant, the shape of the pins differs within the groups and / or from one group to another. The pimples can be of any shape. The spikes advantageously have a semi-conical, asymmetrical shape, having a first face having a first shape, particularly flat, and a second face having a second shape, for example non-planar, in particular rounded. In this case, all the plane faces are preferably circumferentially oriented in the same direction. In a variant, the pins have a cylindrical or tapered shape, in particular conical, frustoconical or pyramidal shape, in particular with a hexagonal base. The cross section of the pins is advantageously semicircular (so-called half-moon). In a variant, the cross section of the pins is of substantially circular, elliptical or semi-elliptical shape, or other, for example polygonal, in particular hexagonal.

The spikes can each extend from the core along an axis of elongation perpendicular to the surface of the core, at the point of connection of the spikes to the core. Alternatively, the spike delimitation forms an angle different from 90 ° with the fame surface at the point of connection of the spikes to fame. The free ends of the pins of the applicator member define an envelope surface of the applicator member, which is for example cylindrical of revolution over at least part of its length. 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 of the portion of the core carrying the pins.

The envelope surface may also have a cross section which varies over all or part of the length of the application structure. The cross section of the envelope surface may for example admit one or more extrema and for example at least one local minimum and two local maxima. The diameter of the envelope surface passing through the top of the pins of smaller height may be between 3 mm and 6.5 mm. The diameter of the envelope surface of the applicator member passing through the apex of the spikes of greater height may be between 5 mm and 12 mm. The pins may be terminated by a rounded free end, particularly hemispherical, whose radius may be between 0.01 mm and 0.2 mm. The longitudinal rows of pins are advantageously rectilinear. The number of longitudinal rows can be even. There may be at least eight longitudinal rows of pins, especially between twelve and thirty-six rows, including sixteen rows.

The core may have a cross section, taken perpendicularly to its longitudinal axis, of any shape, in particular circular. The largest cross section of the core, namely its diameter in the case where the cross section of the core is circular in shape, can be between 1.5 mm and 3.2 mm. The core and the pins can be molded in the same material, or alternatively can be made in at least two different materials. In exemplary embodiments of the invention, the pins are made by overmolding on the core. The core and / or the pins are preferably made of a thermoplastic material. Applicator The applicator may comprise a rod carrying at one end the applicator member and being attached at a second end to a gripping member. The core may be solid, being for example molded with a fixing end to the rod of the applicator. In a variant, the soul is hollow. The applicator member may be fixed on the rod by snapping, gluing, welding, crimping, stamping, stapling, forced insertion, cold or hot, for example by mounting a tip of the application member. in a housing of the stem. Alternatively, the rod is received in a housing provided in the core. The rod and the applicator member may be molded in one piece, in the same thermoplastic material or not.

The pins may be made of a material more or less rigid than a material used to make the rod of the applicator to which the core is connected.

The soul can relax along a longitudinal axis making, in at least one point of its length, a non-zero angle with longitudinal faxe of the rod to which is fixed fame. The applicator 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 apparent length of application may be between 15 mm and 35 mm, better between 22 mm and 29 mm. The applicator may comprise in total between 80 and 1296 pins, better between 96 and 864 pins. APPLICATION DEVICE The subject of the invention is also a device for packaging and applying a product to the eyelashes and / or the eyebrows, comprising an applicator according to the invention, as defined above, and a container containing the product to be apply.

The gripping member of the applicator may constitute a cap for closing the container. The container may comprise a dewatering member adapted to dewater the rod and the applicator member. The product is preferably a mascara.

The invention will be better understood on reading the following detailed description of a nonlimiting example of implementation thereof, and on examining the appended drawing, in which: FIG. a schematic view in elevation, with partial longitudinal section, of an exemplary packaging and application device produced in accordance with the invention, - Figure 2 represents in isolation, in perspective, the application member of Figure 1, - FIG. 2A shows a detail of the applicator of FIG. 2, FIG. 3 is a sectional view of a detail of the application structure of FIG. 2, FIG. 4 is a flat developed view illustrating the arrangement of a portion of FIG. studs on the surface of the fame of an applicator according to the invention, and - Figure 5 is a section VI-VI of the application of Figure 2. Figure 1 shows a device 1 for packaging and application made conform Etiment to 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 container 3 comprises, in the example considered, a threaded neck 4 and the applicator 2 comprises a closure cap 5 arranged to be fixed on the neck 4 in order to close the container 3 tightly in the absence of use , the closure cap 5 also constituting a gripping member for the applicator 2. The latter comprises a rod 7 of longitudinal axis Y, which is connected at its upper end to the closure cap 5 and at its lower end to an applicator member 8. The latter comprises a core 10 carrying pins 18, relaxing from the core 10 and all around it. As seen in FIG. 2, the first longitudinal X-shaped pie 18 from the stem 7 is disposed at a non-zero distance from the proximal end 11 of the core. The last pin 18 according to longitudinal fax X of fame 10 starting from the rod 7 is disposed at a non-zero distance dd from the distal end 12 of the core 10. The container 3 also comprises a wiper member 6, inserted in the collar 4.

This wiper member 6, which may be of any suitable type, comprises in the example in question a lip arranged to dewater the rod 7 and the applicator member 8 when the applicator 2 is removed from the container 3. The lip defines a wiper orifice 6a of diameter 9, adapted to that of the rod 7. The wiper member 6 may be made of elastomer. The wiping orifice 6a is for example circular in shape.

The diameter 9 of the wiping orifice 6a is typically between 3 and 5.75 mm. 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 a different section, the fixing of the cap 5 on the container 3 can then be performed otherwise than by screwing, if necessary. The dewatering member 6 is adapted to the shape of the rod 7 and that of the applicator member 8, as appropriate. Preferably and as in the example considered, the longitudinal axis Y of the rod 7 is rectilinear and coincides with the longitudinal axis of the container 3 when the applicator 2 is in place thereon, but it does not leave the of the present 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 of the wiper member 6, so as not to mechanically stress it excessively during storage. The applicator member 8 may comprise, as illustrated in FIG. 2, a nozzle 9 enabling it to be fixed in a corresponding housing of the rod 7. The fixing of the applicator member 8 on the rod 7 can be done by any means and particularly by force fitting, latching, gluing, welding stapling or crimping, in this housing. Referring to Figure 2, we see that the core 10 is of elongate shape along a longitudinal axis X, which is rectilinear in the example described. The longitudinal axis X may be central, as illustrated. The apparent length H of the applicator 8 is for example equal to 25.5 mm. In the illustrated example, the pins 18 extend from the core 10 each along an axis of elongation W perpendicular to the surface of the core, at the point of connection of the pin 18 to the core 10. In the example described, the pins 18 are arranged in groups of pins 15, 16 within sixteen rectilinear longitudinal rows 17, 19, 20, as can be seen in particular in FIG. 2, each longitudinal row 17 of pins being offset axially relative to at consecutive longitudinal rows 19, 20. Preferably, as illustrated, the pin groups 15, 16 are regularly spaced along the longitudinal rows 17, 19, 20 and each comprise two pins 18.

In a variant not shown, the groups of pins 15, 16 comprise more than two pins 18, for example three or four pins. In another variant, the number of pins 18 differs from one group of pins 15 to another, within a longitudinal row 17, 19, 20 and / or from one longitudinal row to the other. Preferably and as in the example described, the spacing Sp between the pins 18 of a group 15, 16 is the same for each group. In a variant not shown, the spacing Sp between the pins 18 of a group 15, 16 differs from one group of pins to another, within a longitudinal row 17, 19, 20 and / or from a longitudinal row to the 'other. This spacing Sp can be between 0.05 mm and 2.5 mm.

In the example considered, the spacing Sg between each consecutive group of pins 15, 16 is advantageously constant within each longitudinal row 17, 19, 20. In a variant that is not illustrated, the spacing Sg is variable, within least one longitudinal row and / or one row to another.

As shown in FIG. 4, the spacing Sg between two consecutive groups of spikes 15, 16, measured at the base of the web 10, between the outer flanks 18a of the last spike of the first group 15 and the first spike of the second group 16, along the length of the row 17 containing the groups, may be between 0.45 mm and 1.5 mm. Each longitudinal row 17 of pins 18 is advantageously axially offset relative to the consecutive longitudinal row 19 so that each group of pins 15 of the offset row 17 occupies the same axial position as the free space 14 of pins between two groups of pins 15, 16 of the consecutive row 19, as can be seen in particular in Figures 2, 2A and 4. The pins 18 of a longitudinal row in two advantageously all occupy the same axial position along the longitudinal fax X of the core 10, as shown in FIG. 2, for example between the longitudinal rows 17 and 20. As shown in Figure 4, the axial offset Da between a longitudinal row 17 of pins 18 and the consecutive longitudinal row 19 is greater than the length Lg of a group of pins 15 of said consecutive row 19.

As represented in particular in FIG. 2, one longitudinal row in two comprises a pin 18 isolated at the proximal end end 11 of the ankle 10. A simple ring 22 of pins 18 is thus advantageously arranged at the proximal end 11 of the 10. The longitudinal rows comprising this isolated pin can have one pin less than the other rows, for example thirteen pins 18 against fourteen pins. As can be seen in FIGS. 4 and 5, the implantation of the pins 18 may be such that the longitudinal angle around X of the web 10 between two consecutive rings 20 and 21 of pins 18, each formed by pins 18 occupying the same axial position on longitudinal fax X of the core 10, or non-zero, being for example equal to half the angular pitch fi between two consecutive pins of a ring. In the example considered, the pins 18 are advantageously of the same height within each group of pins 15, 16. In a variant not illustrated, the height of the pins 18 within the same group varies.

Preferably and as in the example described, within the longitudinal rows, the height of the pins 18 decreases towards the distal end 12 of the fame 10. In a variant not shown, the height of the pins 18 is constant along Longitudinal Faxe X of Fame 10.

The height hp of the pins 18 may be between 0.15 mm and 0.45 mm. The width lp of the pins 18 may be between 0.1 mm and 1 mm. The thickness ep of the pins 18 may be between 0.1 mm and 0.85 mm. The pins 18 may have various shapes, varying or not within a group 15, 16 and / or from one group to another. In the example under consideration, and as can be seen in particular in FIG. 2A, all the pins 18 are of semi-conical shape, having a first flat face 18b, and a second rounded face 18c. All flat faces 18b are preferably circumferentially oriented in the same direction. The invention is however not limited to a particular type of pins. In the example under consideration, the free ends 28 of the pins 18 define an envelope surface S of the applicator member 8, of rectilinear longitudinal axis and coincident with longitudinal fax X of the core 10, symmetrical of revolution about said axis X. The pins 18 are made, in the example in question, in one piece by molding thermoplastic material with core 10. It is possible to use for molding the application body 8 any thermoplastic material, relatively rigid or not, for example SEBS , a silicone, a latex, a reinforced slip material, butyl, EPDM, a nitrile, a thermoplastic elastomer, a polyester, polyamide, polyethylene or vinyl elastomer, a polyolefin such as PE or PP , PVC, EVA, PS, SEBS, SIS, PET, POM, PU, SAM, PA, PMMA. It is also possible to use a ceramic, for example based on alumina, a resin, for example of the urea-formaldehyde type, possibly a graphite-laden material. It is possible to use the materials known under the trade names Teflon, Hytrel, Cariflex®, Alixine, Santoprene, Pebax® and Pollobas, this list not being limiting. To use the device 1, the user unscrews the closure cap 5 and extracts the applicator member 8 from the container 3. After passing through the applicator member 8 of the wiper member 6, a certain amount of product P remains in the spaces free pins 14 created between the groups of pins 15, 16, creating product tanks P along the entire length of the core 10 and all sides, to load satisfactorily eyelashes and / or the eyebrows in product P. In addition, the eyelashes and / or the eyebrows are separated satisfactorily, avoiding the formation of packets, thanks to the axial offset present between the longitudinal rows 17, 19, 20 of pins 18.

Of course, the invention is not limited to the embodiment which has just been described. At least one of the core 10 and a pin 18 can be flocked, or receive any hot or mechanical treatment. The phrase "comprising one" shall be understood as being synonymous with "comprising at least one", and "between" means inclusive, unless the contrary is specified.
