COSMETIC APPLICATOR AND ASSOCIATED APPLICATOR ASSEMBLY

The invention relates to an applicator for a cosmetic product and an associated applicator assembly.

Applicator assemblies are known which make it possible to apply a liquid or viscous cosmetic product, in particular mascara, to the eyelashes of a user. These applicator assemblies comprise for example a container containing the cosmetic product and an applicator designed to be removably attached to the container.

This container generally includes a reservoir designed to store the cosmetic product.

The reservoir comprises walls which delimit an internal space in which the cosmetic product is contained and a neck defining an opening through which the cosmetic product, carried or driven by the applicator, can be extracted.

The applicator assembly generally comprises a plug adapted to be fixed to the neck, a rod extending from the plug and an applicator fixed to a free end of the rod.

The applicator includes a core and a plurality of protrusions extending from the core.

When the cap is fixed on the neck, the rod and the applicator extend inside the reservoir. The applicator is immersed in the cosmetic product contained in the reservoir.

To use the applicator, the user detaches the cap from the neck and extracts the applicator from the container.

It is known to produce applicators, in particular by molding, which comprise a core and pins coming from the core. The arrangement of the pins and the shape of the core then makes it possible to produce a particular makeup effect. That said, the user of such applicators is often limited in the use they can make of it.

An object of the present invention is to provide an applicator with molded protuberances making it possible to obtain new makeup effects. Another object of the invention is to allow a user to have several makeup effects from the same applicator.

To meet this need, the invention provides an applicator element for cosmetic product comprising a core, the core extending from a proximal end to a distal end in a main direction of longitudinal extension of the core, called the axis longitudinal of the core, the core comprising two surfaces including a substantially concave surface and a substantially convex surface, each surface being curved around a direction substantially parallel to the longitudinal axis of the core, each of the substantially concave surfaces and substantially convex being provided with pins, the substantially concave surface having a density of pins different from that of the substantially convex surface, the core comprising a section separating the two surfaces which is substantially concave and substantially convex from one another, the section of the core being provided with pins, the pins projecting from the edge.

The applicator according to the invention comprises several zones including a convex part in particular suitable for styling an eyelash fringe, a concave part in particular suitable for loading this eyelash fringe with cosmetic product and the slice which makes it possible to reach certain specific zones for example the smallest lashes in this lash fringe. In this way, each zone allows a different makeup effect.

The user then benefits from several makeup effects using a single applicator. Thanks to the invention, makeup is faster, simpler and more natural.

According to different embodiments, which can be taken together or separately:

the density of spikes on the substantially concave surface is lower than the density of spikes on the substantially convex surface, the spikes of at least one of the substantially concave or substantially convex surfaces extend in a direction substantially orthogonal to the axis longitudinal of the core and are parallel to each other, the pins coming from the edge extend in a longitudinal direction orthogonal to the longitudinal axis of the core, the applicator element further comprises a group of protruding pins substantially from the distal end of the core and away from the proximal end of the core, the width of the wafer, the width being measured as the distance between the substantially concave and substantially convex surfaces one from the other, decreases when one moves from the proximal end to the distal end of the core, the height of the pins coming from the convex surface and from the surface c oncave, the height being measured as the distance between the surface from which they protrude and their free end, increases and decreases as one moves from one end to the other of the core, the spikes extend from the core at one free end, the free ends of the pins coming from the convex and concave surfaces together forming an envelope of substantially spherical or ovoid shape, the core has a width which increases and then decreases from one end to the other of the 'soul, the width of the soul being measured as the distance separating the two most distant points from each other of a cross section of the soul, the cross section of the soul being perpendicular to the longitudinal axis of the core.

The invention also relates to an assembly comprising an applicator element according to any one of the preceding claims and a container designed to receive a liquid or viscous cosmetic product, the container being provided with a reservoir and a wringer, the wringer having a wiping orifice and being designed to modify a distribution of the cosmetic product on the applicator element during the passage of the applicator element from the interior of the reservoir to the exterior thereof, in which the applicator element is designed to deform the wiper as it passes through it. According to different embodiments, which can be taken together or separately:

the largest transverse dimension of the applicator element, measured perpendicular to the longitudinal axis of the core, is greater than the internal diameter of the wiper at the wiper orifice of the wiper, the applicator element is designed so that the pins coming from the convex surface of the core are more wrung out by the wiper than the pins coming from the concave surface of the core.

Other characteristics, objects and advantages of the invention will emerge from the description which follows, which is purely illustrative and not limiting, and which should be read with reference to the appended drawings in which:

As illustrated in particular in Figures 1 and 2, the invention relates to an applicator element for cosmetic product, in particular for mascara. The applicator element 1 comprises a core and pins 14 coming from the core. The core 10 and the pins 14 are for example from molding.

The applicator element is here made of a plastic material, which facilitates molding in particular of complex shapes.

The core 10 has a proximal end 101 and a distal end 102. The core extends longitudinally in a main direction of longitudinal extension from its proximal end 101 to its distal end 102. In the following, the main direction of the longitudinal extension of the core 10 is also called the longitudinal axis (X) of the core 10. The distal end 102 of the core 10 here corresponds to a free end 102 of the core 10.

The applicator element 1 further comprises a sleeve 11 connected to the proximal end 102 of the core 10. The sleeve 11 and the rest of the applicator element 1 are here made from material. They are united to each other. Here, the sleeve 11 extends longitudinally in a direction coincident with the longitudinal axis (X) of the core 10.

The core 10 here comprises two opposite surfaces 12, 17 to each other. One of the surfaces 12 is a concave or substantially concave surface 17. The other of the surfaces is a convex or substantially convex surface 12. Each of the surfaces 12, 17 is here curved around a direction substantially parallel to the axis longitudinal (X) of the core. The directions around which each of the convex 12 and concave 17 surfaces are curved are not necessarily confused with each other. Here, the two surfaces 12, 17 extend substantially parallel to one another.

In this way, the core 10 is here curved, curved and / or folded around its longitudinal axis (X).

In an alternative embodiment which does not depart from the scope of the invention, the core 10 may be curved both around its longitudinal axis (X) and around another axis, in particular orthogonal and / or perpendicular to its longitudinal axis (X).

In particular, a user observing the core 10 along the longitudinal axis (X) of the core 10 would visualize a shape roughly resembling a C.

In the following, a thickness of the core 10 is defined as the distance separating the two surfaces 12, 17 of the core 10 from one another.

The core 10 comprises a wafer 19. The wafer 19 of the core 10 extends in a manner substantially orthogonal to the concave 17 and convex 12 surfaces of the core 10. The wafer 19 of the core 10 connects the two surfaces 12, 17 of the core 10. In particular, the edge 19 of the core connects contours of each of the two surfaces 12, 17 of the core 10 together. The edge 19 of the core 10 corresponds to a lateral surface of the core 10. It comes from the contours of the convex 12 and concave 17 surfaces of the core 10. The edge 19 of the core 10 is thus located at a periphery of each of the concave 17 and convex 12 surfaces.

The edge 19 of the core 10 has a width. The width of the slice 19 is here equal to the thickness of the core 10 at the contour of the concave 17 and convex surfaces 12. In other words, the width of the slice 19 is equal to the distance separating the contours of the concave surfaces 17 and convex 12 from each other. Here, the width of the slice 19 is measured substantially orthogonal to the longitudinal axis (X) of the core 10.

It is noted that the width of the slice 19 is not here constant from one end 101, 102 to the other of the core 10. In particular, the width of the slice 19 decreases progressively when one moves from the proximal end 101 to the distal end 102 of the core 10. Advantageously, this characteristic gives the core 10 a substantially tapered shape. The tapered shape of the core 10 makes it possible to achieve, in particular with the distal end 102 of the core 10, a high degree of precision when making up the eyelashes.

For example, the width of the wafer 19 is of the order of a few millimeters (mm), for example between 0.2 and 2 mm.

The applicator element 1 further comprises pins 14 coming from the core 10. The pins 14 are here protuberances which extend from a surface of the core 10. The pins 14 comprise a base 147 and a free end 149 The base 147 of each pin 14 is merged with the surface of the core from which it originates.

Each of the pins 14 here extends longitudinally in a main direction of longitudinal extension of the pin, also called the longitudinal axis of the pin, between its base 147 and its free end

149. Here the pins 14 are made from material with the core 10. The pins 14 are for example molded with the core 10.

The pins 14 here have substantially the shape of a half-trunk of cones. In other words, they have a shape of a truncated cone cut in half in the direction of a height of the truncated cone. The pins 14 have a flat face 141 and a rounded face 143. The planar 141 and rounded 143 faces of each pin 14 extend longitudinally from the base 147 of the pin 14 to the free end 149 thereof. Each spike 14 further comprises a flat surface 149 coinciding with the free end 149. The flat surface 149 of each spike 14 extends in a plane substantially orthogonal to the longitudinal axis of the spike 14.

The applicator element 1 comprises three families of pins 14 including a first family of pins 14a from the convex 12 and concave surfaces 17 of the core, a second family of pins 14b from the edge 19 and a third family of pins 14c from of an area close to the distal end 102 of the core 10. Advantageously, each of the families of pins 14a, 14b, 14c allows a different makeup effect, as will be detailed later.

Each of the concave 17 and convex 12 surfaces of the core 10 is provided with pins 14a of the first family. The longitudinal axes of the pins 14a extend in a direction substantially orthogonal to the longitudinal axis (X) of the core 10. It will also be noted that the pins 14a, as illustrated in particular in FIGS. 2 and 3, independently of the the fact that they originate from the concave surface 17 or from the convex surface 12, all extend parallel to the same direction substantially orthogonal to the longitudinal axis (X) of the core 10. The pins 14a do not extend not necessarily perpendicular to the convex 12 or concave 17 surface from which they originate. Here, the pins 14a coming from each of the concave 17 and convex 12 surfaces extend along longitudinal axes parallel to each other.

As is partially visible, in particular in FIG. 5, the pins 14a of the first family of pins are here arranged on the convex 12 and concave 17 surfaces according to a symmetry with respect to a plane passing through the longitudinal axis (X) of the core and parallel to the longitudinal axes of the pins 14a. In this way, the pins 14a are here oriented opposite to each other so that their respective planar faces 141 face each other and / or are oriented in directions opposite to each other. In particular, the planar faces 141 of all the pins 14a coming from the convex 12 and concave 17 surfaces are all oriented towards the plane of symmetry.

Advantageously, this orientation of the pins 14a coming from the convex 12 and concave 17 surfaces allows in particular a better distribution of the cosmetic product on the core.

Here, it is noted that the parallelism of the pins 14a between them facilitates the molding and then the demolding of the applicator element.

In the following, the convex part 120 of the applicator element 1 is called a part of the applicator element 1 composed of the convex surface 12 of the core 10 and the pins 14a which result therefrom. The concave part 170 of the core 10 is called a part of the applicator element 1 composed of the concave surface 17 of the core 10 and the pins 14a which result therefrom.

The convex 12 and concave 17 surfaces each have a density of pins 14a.

Advantageously, the density of pins 14a at the concave surface 17 of the core 10 is different from the density of pins 14a at the convex surface 12 of the core 10. In particular, here, the density of pins 14a at the concave surface 17 of the core 10 is lower than the density of pins 14a at the convex surface of the core 10. In other words, the concave surface 17 of the core 10 is provided with fewer pins

14a as the convex surface 12 of the core 10.

This difference in density of pins 14a between the concave surface 17 and the convex surface is advantageous in that it allows different makeup effects depending on whether the user brings one or the other of these surfaces 12, 17 into contact. of her eyelashes. In particular, the high density of pins 14a at the convex surface 12 of the core makes it possible to separate and style the eyelashes. In addition, the association of a high density of pins 14a with a convex surface makes it possible to separate and style the eyelashes while avoiding an overload of mascara.

In addition, the low density of pins 14a at the concave surface 17 makes it possible to give the concave part 170 of the core 10 a high loading power in mascara. In addition, the combination of a low density of pins 14a with a concave surface makes it possible to further increase the loading power of the applicator element 1.

The pins 14a from the concave 17 and convex 12 surfaces of the core 10 have a height measured as the length of a segment connecting the base 147 of each pin 14a to its free end 149. Here, the height of the pins 14a increases then decreases as we move, along the soul

10, from the proximal end 101 to the distal end 102 of the core 10.

In addition, as illustrated in Figures 2 and 3, the free ends 149 of the pins 14a from the concave surface 17 of the core 10 and the convex surface 12 of the core 10 together form a ίο envelope (E). This envelope (E) has substantially an ovoid or pine cone shape. As a variant, the envelope (E) has substantially the shape of a sphere.

In addition, this envelope (E) has, as illustrated in FIG. 3, along the core 10 and from one end to the other of the core 10, a cross section, of circular or substantially circular shape, the cross section of the envelope (E) being defined as orthogonal to the longitudinal axis of the core 10. This shape allows in particular a homogeneous makeup of the eyelashes of the user when the latter pivots the core 10 around its longitudinal axis.

Advantageously, the cross section of the envelope (E) has a diameter of approximately mm.

As illustrated in particular in FIG. 2, the edge 19 of the core 10 is itself provided with pins 14b of the second family. Here, the pins 14b from the edge 19 extend substantially orthogonal to the edge 19. The pins 14b further extend substantially orthogonal to a main direction of longitudinal extension of the pins 14a from the concave surfaces 17 and convex 12 of the core 10. The pins 14b from the edge 19 further extend substantially orthogonal to the longitudinal axis of the core 10. It is also noted that the pins 14b from the edge 19 of the core 10 are here arranged in a substantially staggered fashion along the edge 19.

Here, the pins 14b coming from the wafer 19 extend from the wafer 19 while deviating substantially from each other. Here, we note that the positioning of the pins 14b from the edge

19 facilitates the molding and then demolding of the applicator element.

The pins 14b from the edge 19 have a length of between 1 and 2 mm, for example around 1.5 mm. This length of the pins 14b is chosen so as to prevent these pins 14b from being torn off during a wringing of the applicator element 1 while allowing them to be long enough to participate for example in the separation of the eyelashes.

As illustrated in particular in FIGS. 1 and 2, the core 10 is further provided, at its distal end 102, with pins 14c from the third family of pins. These pins 14c come from a zone close to the distal end 102 of the core 10. They substantially form a crown around the longitudinal axis (X) of the core 10. In particular, the pins 14c of the third family of spikes are arranged so that their bases form a crown around the distal end 102 of the core 10. They are here arranged in close proximity to one another. In other words, the bases of the pins 14 are substantially aligned along a circle substantially included in a plane orthogonal to the longitudinal axis of the core 10. As can be seen in particular in FIG. 5, we note that the planar faces 141 of the pins 14 are oriented towards the outside of the circle. The rounded faces 143 of the pins 14c are oriented towards the inside of the circle, that is to say that they face the longitudinal axis (X) of the core 10.

It will also be noted that here the longitudinal axes of the pins 14c arranged at the distal end 102 of the core 10 extend in a direction and in a direction moving away from the proximal end 101 of the core 10. In other words, when one moves along each of the pins 14c of the third family of pins, from its base 147 to its free end 149, one moves away from the proximal end 101 of the core. Advantageously, this arrangement of the pins 14c allows them to retain a large amount of mascara during the passage of the applicator element through a wringer.

The pins 14c coming from the distal end 102 of the core 10 has an extension dimension, measured as the length of an orthogonal projection of the pins 14c on the longitudinal axis (X) of the core 10, preferably between 1 and 3 mm, advantageously between 2.5 mm and 3 mm. This dimension of extension of the pins 14c coming from the distal end 102 of the core 10 makes it possible to reach and precisely define small eyelashes.

Note also that the orthogonal projection of the core 10 on a plane perpendicular to the longitudinal axis of the pins 14a from one of the concave 17 or convex 12 surfaces of the core 10 has a substantially oval shape.

A length of the core 10 is further defined as being the distance separating the proximal end 101 from the distal end 102 of the core 10. Preferably, the length of the core is between 8 and 15 mm. More advantageously, the length of the core is between 12 and 14 mm.

A width of the core 10 is also defined as the largest dimension of a cross section of the core 10, the cross section of the core 10 being orthogonal to the longitudinal axis of the core 10. In other words, the width of the core 10 is defined as the distance separating the two points of the core 10 which are the most distant from each other in a cross section of the core 10. Here, the width of the core 10 increases then decreases when one moves along the longitudinal axis of the core 10, from one end to the other of the core 10. Advantageously, the width of the core is between 9 mm and 10 mm.

The invention also relates to an applicator assembly comprising an applicator and a container. The applicator advantageously comprises a plug, a rod and the applicator element 1 as previously described. The rod comes from the plug and extends between the latter and the applicator element 1. The rod, the plug and the applicator element 1 are not illustrated here.

The container allows the storage of the cosmetic product, here mascara. The container comprises a reservoir and a wringer 2.

The tank is designed to store mascara. It is for example of substantially cylindrical and elongated shape. The reservoir has a lower end and an upper end and extends longitudinally in a main direction of extension. The reservoir includes a base at its lower end and an opening at its upper end. The base of the tank can serve as a support surface for the tank. The reservoir further comprises a side wall, for example of cylindrical shape, which extends from the opening at the base of the reservoir.

The opening of the reservoir allows the passage of the applicator and the extraction of the mascara from inside the reservoir. The applicator cap is designed to be able to close the container at the upper end of the reservoir. The applicator assembly is designed so that when the cap closes the container, the rod and the reservoir of the applicator are located inside the reservoir, in contact with the cosmetic product.

A recharging position and a position for using the applicator are defined below. The reloading position of the applicator corresponds to a position of the applicator when the applicator element 1 mascara is inside the reservoir in contact with the cosmetic product contained in the reservoir. The position of use corresponds to a position of the applicator when the applicator element 1 is outside the reservoir.

The wiper 2 is arranged at the opening of the tank, inside the latter.

The wiper 2 has a substantially tubular or cylindrical shape. The wiper 2 comprises a lower end 201 and an upper end 202 and extends longitudinally from one to the other along a longitudinal axis of extension (Y) of the wiper 2. Once the wiper 2 is assembled with the reservoir, the upper end 202 of the wiper 2 is designed to be arranged at the opening of the reservoir. The lower end 201 of the wiper is designed to be arranged between the upper end 202 of the wiper and the lower end of the tank.

The wiper 2, as illustrated in FIGS. 4 to 10, is designed to wring the applicator element when the applicator passes from the recharging position to the use position. In particular, the wiper is designed to modify a distribution of the cosmetic product on the applicator element 1 when it passes through the wiper 2.

As can be seen in particular in FIGS. 4 and 5, the wiper 2 here comprises a side wall 24 and a base 25. The side wall 24 is of substantially cylindrical shape and extends from the lower end 201 to the upper end 202 of the wiper 2 substantially parallel to the extension axis (Y) of the wiper 2. Here, the side wall 24 extends from a periphery of the base 25.

As illustrated in particular in FIG. 5, the base 25 of the wiper 2 is arranged at the lower end 201 of the wiper 2. It is here of planar shape and substantially circular. It extends orthogonal to the longitudinal axis (Y) of the wiper 2. The base 25 is provided with a wiping orifice 250 at its lower end 201. The wiping orifice 250 is designed to allow the passage of the applicator element 1 and to allow wringing of the applicator element 1.

The wiper 2 further comprises an opening 27, called the upper opening 27, at its upper end 202. Thus, the side wall 24 of the wiper 2 extends longitudinally between the base 25 of the wiper 2 and the opening upper 27 of wiper 2.

The upper opening 27 and the wiping orifice 250 when it is not deformed by the passage of the applicator element 1 are both of substantially circular shape and each have a diameter. The diameter of the upper opening 27 is here larger than the diameter of the wiping orifice 250. In this way, during the passage of the applicator from its recharging position to its position of use, the element applicator 1 is wrung intensively at the lower end 201 of the wringer 2 and the wringing orifice 250.

As can be seen in particular in FIGS. 6 and 7, it is further noted that the wiper 2 has a length, measured as the distance separating its lower end 201 from its upper end 202, substantially equal to the length of the applicator element 1.

The wiper 2 is here provided with a circular shoulder 23 which facilitates an attachment of the wiper 2 to the container.

The wiper 2 is designed in a flexible material. For example, the wiper 2 could be designed in rubber. The applicator element 1 is designed to deform, here elastically, at least part of the wiper 2 during the passage of the applicator from the recharging position to the position of use.

In addition, as illustrated in particular in FIG. 7, the applicator element 1 has a larger transverse dimension greater than a diameter of the wiping orifice 250 of the wiper 2 when the latter is not deformed. In addition, here, the largest transverse dimension of the core 10 is also greater than the diameter of the wiping orifice 250, the diameter being measured before deformation of the wiping orifice 250 by the applicator element 1.

As can be seen in FIG. 10, when the applicator element 1 passes through the wiper 2, the wiping orifice 250 deforms and becomes substantially oblong. In this situation, the wiper 2 in particular and significantly scrapes the edge 19 of the core 10 and the convex part 120 of the core 10. On the other hand, the concave surface 17 of the core 10 is little wrung out, in particular because it remains at least partly at a distance from a periphery of the wringing orifice 250.

Indeed, the applicator element 1 is designed so as to deform the wiping orifice 250 of the wiper 2 during the passage of the applicator element 1 through the wiping orifice 250. The deformation of the wiper 2 by the applicator element 1 is made in particular in a direction perpendicular to the longitudinal axis of the wiper 2. Indeed, the applicator element 1 is here designed in a more rigid material than the material from which the wringer 2.

Due to the curved and / or curved shape of the core 10, the pins 14a coming from the concave surface 17 of the core 10 are less wrung out. In other words, the pins 14a coming from the concave surface of the core 10 are less exposed to the wiper 2 than the pins 14a coming from the convex surface 12 of the core 10. This characteristic makes it possible to retain a high loading power. of the concave part 170 of the core 10 when the applicator is in the position of use.

On the one hand, advantageously, the concave surface 17 forms a hollow which allows a large storage of mascara on the applicator element. This concave surface 17 can thus be used for efficient loading of the eyelashes with mascara.

On the other hand, the convex surface 12 will tend during the use of the applicator element to allow the conservation of a lesser amount of mascara. This convex shape, advantageously, can be used for combing the eyelashes while avoiding excessive loading of the eyelashes with mascara.

Thus, advantageously, when the applicator has passed through the wiper 2 and is in the position of use, the applicator element 1 is lightly loaded with mascara at its convex part 120 while retaining a large load of mascara at the level of the concave part 170 of the applicator element 1.

The deformation of the wiper 2 makes it possible to intensify the wiping of the concave part 170 of the applicator element 1. In fact, under the effect of the deformation of the wiping orifice 250, the base 25 of the 'wringer 2 tends to follow the shape of the convex part 120 of the applicator element 1 while approaching it. Likewise, the pressure of the wiper 2 on the edge 19 of the core 10 is particularly high during the passage of the applicator element 1 through the wiping orifice 250. This deformation increases the wiping power of the wiper 2 on the convex part 120 of the core 10 and on its edge 19.

On the other hand, it should be noted that the tapered shape of the core 10, mentioned above, makes it possible to facilitate passage of the applicator element 1 through the wiping orifice 250. This tapered shape of the core and therefore of the applicator element 1 in particular avoids damaging the wiper 2 when the applicator passes through the wiper 2.
