Definitions

• Applicator device for a fluid or pasty cosmetic product, typically mascara
• the present invention relates to the field of applicators of fluid or pasty cosmetic product and more particularly of mascara.
• the invention is concerned with the application means in the form of a brush or a comb.
• Said applicator forms with a mascara reservoir in which it is insertable, a mascara dispenser, said manual gripping means of the body serving as a cap for the reservoir by means of cooperation means located on the one hand on said cap and on the other hand share on the mascara tank.
• a solution provided by the patent application US 2008/0011317 is a brush whose distribution of the pins is no longer made in uniform rows but is made in rows spaced laterally around the body of the brush at unequal angles of a row to the other, different pin densities, as well as different diameters and pin lengths.
• this solution is relatively complex and does not guarantee a regular load of mascara on the eyelashes and / or on the spikes while keeping a sufficient separation of the eyelashes.
• a solution envisaged in the prior art for improving the mascara load of the brushes is the use of spikes having a flat face to collect the mascara while their non-planar face participates in the separation of the eyelashes.
• Such an applicator is especially described in EP 1 872 682.
• These pins are arranged in rows parallel to the longitudinal axis of the brush, all the pins of a row having their flat face on the same side, that is to say say that they are aligned and that their non-planar faces are on the same side with respect to this line.
• the brushes of this type do not have maximum efficiency since the rows of spikes comprising only the flat faces of the spikes on one side, do not participate in the separation of the eyelashes and the rows of spikes having only the non-contact faces. Plane eyelashes do not participate in the mascara load. With this type of brush, the user is therefore forced to make several passes on his eyelashes while reversing the movement of the brush to ensure that a sufficient load of mascara is recovered.
• a device for applying a product to the eyelashes and / or the eyebrows comprising: a support extending along a longitudinal axis, a first row and a second row of teeth made monolithically with the support, being connected on the same side of the support and extending over at least a quarter of the length of the support, at least one of the rows comprising two teeth extending at least partially from each other and another of a geometric separation surface extending along this row, at least two teeth extending in non-parallel directions.
• Such a support is shown as always having at least one plane face from which protrude the teeth of two rows.
• Each row of teeth has staggered teeth on either side of a separation surface so that the teeth may have planar faces opposite one another, that is to say that during a product application with such a comb, the back and forth movement printed with the comb may thus have teeth faces in both directions, adjacent teeth having an axis arranged in different directions.
• the teeth when the flat faces are on both sides, the teeth have different directions, which does not allow either, a distribution of the mascara load and optimal separation of eyelashes.
• No. 5,086,793 describes a comb whose core consists of two parts slidably mounted relative to one another. At the junction between these two parts of the soul comb half-teeth are formed protruding and have a flat face extending normally to the core and aligned along a central line so as to be thus facing the opposite face to side of the central line.
• the two parts of the soul are realized sliding relative to each other. In this way, the sliding and the half-tooth shape allows for a spacing between the half-teeth which is modifiable between a maximum spacing and a minimum space where the half-teeth are facing to form a single tooth .
• Such a comb has certain advantages but it also has the disadvantages of its advantages. Indeed, it is well known that the mascara which is a relatively viscous fluid tends to dry relatively quickly and we realize very quickly that the sliding of the two parts of the soul will be difficult to implement or even blocked.
• EP 1 070 468 there is described a brush for makeup eyelashes as well as eyebrows with the same tool and which also allows to curl and lengthen the eyelashes.
• Such an applicator has a rod provided with rows of teeth having a flat face, said planar faces being formed on either side of a separation surface.
• teeth extend perpendicular to a face when the core has a polygonal cross section.
• the projecting elements extend tangentially to the core. Makeup remains less effective than a brush with at least six rows of teeth all around a soul.
• EP 1 342 428 proposes in particular a comb for the eyelashes and / or the eyebrows.
• a set of teeth having a planar face aligned along a separation surface. These teeth extend from a flat face of a support of polygonal section or it is proposed to make elements protruding from a core of circular section these elements being in the form of arcuate segments.
• the purpose of such a comb is to be able to modulate the space between the projecting elements to allow to comb the eyelashes as well as the eyebrows.
• the invention therefore proposes to solve these disadvantages with a brush that makes it possible to make up the eyelashes very advantageously while allowing a simpler, more regular deposit and with sufficient load.
• the invention provides a brush with which it is possible to define usable areas to create a particular makeup effect.
• the invention thus relates to an applicator device such as a brush of a fluid or pasty cosmetic product, typically mascara comprising:
• a core consisting of a plastic body of circular section, flexible, elongate, having a longitudinal axis and two ends, one of which is intended to be fixed to a manual gripping means,
• a plurality of pins preferably having a planar face, arranged in radial projection from said core, said pins being distributed in a plurality of rows parallel to the longitudinal axis of said core and so that within the same row, the pins are positioned alternately on either side of a central line of said row, with their planar face turned towards the inside of the row, characterized in that said plastic body is of conical shape whose widest diameter is on the side of the end intended to be fixed to the manual gripping means and said flat faces of the pins of the same row normally extend to said conical core, and aligned along the central line, the flat faces thus being oriented in both gyratory directions around the conical core.
• the plane face of a pin aligned with the central line of the row is aligned "facing" the flat faces of the two adjacent pins with a larger or smaller offset, which allows a better load of mascara while that the non-planar faces of the pins can separate the eyelashes.
• the configuration of the pins of the invention makes it possible to have, in the same row and on the same side relative to the central line of alignment of the planar faces, an alternation of planar faces and of non-planar faces, the plane faces of two Adjacent pimples lying further in the same plane normal to the soul. Therefore, between at least two adjacent pins, there is no angle between the peaks of said pins relative to said normal plane.
• the conical core allows the pins all have a base (a surface at the birth of the pin) different from each other.
• the conicity of the core allows the pins all have different height and spacing between them, which allows the user to use the applicator in the area most suitable for the effect of desired makeup (the amount of makeup product load being related to the spacing and height of the pimples).
• the brush according to the invention has characteristics allowing easy makeup effects while providing a simple and fast makeup.
• This conical core further facilitates and secures the introduction of the applicator into a wiper or wiper member and thus limits the bending of the applicator when it is resting in the skirt of the wiper provided on a reservoir of product during the introduction.
• the conical shape of the body of the brush allows with a flexible material to have anyway, a certain rigidity.
• This conical core or beam is therefore more rigid and better resists compression and flexion when applying a thrust on the side of the small diameter.
• the applicator according to the invention thus has a progressive rigidity from its end (small diameter of the cone) to the connection on its stem (large diameter of the cone)
• the axes of the pins of the same row are all parallel, this axis being the axis of symmetry or line forming the center of gravity of the projection of the shape of the pin.
• the pins are therefore all oriented in the same direction relative to the soul.
• the pins of the pins on the same side of the central line of the row are parallel to each other while the pins of the pins located on the other side of the center line of the row are parallel between them, according to a different direction.
• the applicator device according to the invention is a brush and has from 5 to 16, or even 24 rows of pins.
• the density of rows of pins which are distributed angularly in a regular manner around the core makes it possible to modulate the properties of the brush, namely its accuracy, its separation capacity and its load capacity in product. Keep a sufficient and regular load height undisturbed by the spin.
• the flat faces of two adjacent pins of the same row overlap at least partially. This overlap makes it possible to increase the stiffness of the pin without increasing the attack profile in contact with the eyelash.
• the pins of the same row are non-uniformly distributed along said row.
• several configurations are possible as to group in the same row two adjacent pins separated by a space, another group of two adjacent pins.
• the spacing between the groups of pins and the number of pins per group may vary.
• the implantation of the pins in the same row can be performed in a uniform and regular manner, the space between the pins being always the same whether they overlap or not.
• This implantation can also be regular but not uniform.
• the pins have a different height relative to the body and the tips of said aligned pins define an envelope surface of the brush.
• the spikes are formed conically from the core, with a circular, polygonal cross-section such as triangular, always at least with a flat face that will be aligned with the center line of the spine. row.
• the spikes are formed of two distinct materials, the first material forming the core of the spike and the second material forming the bark around said core.
• the advantage of using two different materials is to provide two flexibility and two different touch sensations on the same applicator that can be further identified for example by two different colors.
• a pin on its planar face, comprises a hollow constituting an additional reservoir for retaining the product and favoring the charging of the applicator.
• the pins have different diameters at their implantation on the core which allows to vary the load and flexibility.
