Description

DESCRIPTION

Applicator for applying a cosmetic product

[0001] The present invention relates to an applicator for applying an eyeliner to the eyelids.

[0002] To draw a line on the eyelids, a known practice is to use makeup pencils.

[0003] Devices are also known for masking the eyelids that comprise a reservoir containing the product to be applied and a flexible applicator member for applying the product, where the applicator member is separate from the reservoir, in particular from patent applications FR-A-2633256 and FR-A-2412287. In these devices, the applicator member is formed by a plastic tip that can be flocked or made of felt to retain the product, or also by a tip comprising capillary grooves. The applicator member can also be in the form of a fine brush.

[0004] It is also known from patent US 4370 989 a device comprising a reservoir and an applicator member having a tip, where the latter is supplied with the product from the container by means of the pressure exerted on the walls of the latter.

[0005] With such devices, the user applies the product loaded tip to one side of the eyelid, moving it to the other end, to draw a line in the same way as with a pencil.

[0006] However, it is relatively difficult to draw a regular line, especially with a constant thickness, along the entire length of the line. This is because the user tends to press the tip with varying force while drawing the line, and therefore the tip is pressed to a greater or lesser extent against the eyelid. Consequently, the width of the surface of the tip in contact with the eyelid varies, and therefore that of the line drawn. In the case of a fine brush, it is also quite difficult to get a fine line that is regular.

[0007] Furthermore, it is very difficult to draw an identical line on both lids, since the user never presses in the same way. Specifically, the user is obliged to change hands for each eyelid, so that the less weak hand is used, or to use the same hand for both eyelids and to carry out two different movements.

[0008] Other types of applicators have been described for applying eyeliner compositions to the eyelids with specific hand movements.

[0009] Application WO 99/55187 discloses a device for application to the skin, which is in the form of a pad in the shape of the desired design. The pad is supplied with cosmetic product by applying pressure to a reservoir.

[0010] Patent application EP 1 669 003 describes a device for packaging and applying a cosmetic product, comprising a container containing the product to be applied and a surface delimiting an opening, supplied with product from the container, and that allows to form a design on the skin, especially on the eyelids, without moving over the skin.

[0011] Patent US 6 508 255 discloses an applicator for the eyelids, comprising two arms that are separated at their distal end and are connected to each other by a stabilizing element that forms an application surface, where the latter comes into contact with the skin and deforms to form the desired design in a single application.

[0012] Patent application EP 1466540 refers to a device for applying and packaging a product that is in two parts that are connected to each other by a flexible applicator that comes into contact with the skin, where one of the parts forms a deposit containing the cosmetic product, and the other part forms a lid to close an opening in the reservoir.

[0013] WO 2010/001347 discloses an eyeliner applicator comprising an applicator member that is connected to the handle through a flexible portion.

[0014] DE 102008063063 refers to a pencil for applying a liquid product.

[0015] JP 201547360 discloses an applicator having an applicator member that is connected to the handle through a connecting portion configured to allow rotation of the applicator along an axis parallel to the application surface of the applicator member.

[0016] US 2012/0037180 describes an eyeliner applicator having a multilayer structure.

Finally, US patent application 2007/0017544 describes an applicator for lips, skin or nails, comprising a flat applicator face and a groove adjacent to this applicator face.

These devices do not allow to obtain a great variety of different make-up results, they do not fully adapt to the morphology of the eyes of the users and / or they do not allow to produce particular effects, especially in the outer corner of the eye, in particular a rapid upward movement ending in a point.

[0019] It is necessary to continue improving makeup devices, in particular for the eyelids, and above all to benefit from a device that adapts to the morphology of the users' eyes while allowing to obtain, if desired, a symmetrical makeup result in both eyes, and that allows to easily finish the line produced. There is also interest in a device that is capable of producing an outer rapid motion effect at the outer corner of the eyes.

[0020] The invention aims to satisfy all or some of these needs by proposing an applicator according to claim 1.

[0021] Preferably, towards its distal end, the applicator member tapers in its thickness. For example, the applicator member has a thickness of between 0.1mm and 1.5mm, especially between 0.5mm and 1.5mm, at its distal end.

[0022] The shape of the applicator member allows efficient and precise application of the cosmetic product. The shape of the applicator member also allows, if desired, to draw lines with different thicknesses to vary the effect obtained, for example using the main facet or the side of the applicator member.

The main facet combined with the groove makes it possible to have an application surface whose width of the extension in contact with the skin is relatively independent of the pressure applied by the user.

[0024] The detachment formed by the slit allows the application area to be clearly defined by creating a clean boundary between the application surface formed by the main facet and the rest of the applicator.

[0025] The slit is different from an opening in the applicator member for dispensing a product to be applied.

[0026] Preferably, the applicator member does not have any discontinuities in the groove. For example, the joint of two separately formed parts of the applicator is not located within the length of the slit. Preferably, the applicator member is molded in one piece, that is, the groove is integrally molded with the main facet.

[0027] Preferably, the main facet extends to the distal end. This allows for precise application.

[0028] The width of the main facet can increase monotonically along its entire length. In a variant, the width of the main facet increases with increasing distance from the groove and then decreases towards the distal end. In this case, the width of the main facet can pass through a maximum.

Preferably, the applicator member has, starting from an abscissa in its longitudinal axis corresponding to the proximal end of the main facet, a width that increases or remains substantially constant along at least a part of the length of the applicator member.

[0030] Preferably, the width of the main facet is less than or equal, along its entire length, to the width of the applicator member. For example, it is substantially equal to the width of the applicator member towards the distal end of the applicator member.

[0031] The main facet can extend from the groove. For example, the groove is surrounded on one side by the main facet and is formed, from this side, by a retracted surface of the applicator.

[0032] In this case, the groove can be connected to the main facet, especially by means of a flange or a point. This allows you to clearly delineate the application surface, which contributes to the precision of the application.

[0033] In a variant, the main facet extends from a distance other than zero from the groove. This distance, measured in a direction parallel to the longitudinal axis of the applicator member, is, for example, less than half the length of the slit, and preferably less than one third of the length of the slit, for example less than one sixth. the length of the slit.

[0034] Preferably, the slit does not extend to the proximal end of the applicator member.

The main facet can have a general drop or polygonal shape, especially pentagonal or triangular, in a frontal view.

[0044] The width of the secondary facet may increase towards the distal end of the applicator member.

The secondary facet may be symmetric to the main facet with respect to a plane containing the longitudinal axis of the applicator member.

[0046] Preferably, the applicator member comprises, as seen along the longitudinal axis, opposite the distal end of the applicator member, an end facet that connects the main facet with the rear surface, at least partially.

The end facet has, for example, the shape of a strip. It may have a width, between the rear surface and the main facet, that is constant or decreases with increasing distance from the distal end of the applicator member.

[0048] The end facet can be flat or curved.

With the applicator member extending along a longitudinal axis, the main facet can extend along an axis inclined at an angle a, preferably between 0 ° and 60 °, better still between 0 ° and 45 °. °, even better still between 2 ° and 25 °, with respect to the longitudinal axis of the applicator member. This inclination can facilitate the application of the product to the skin and allows the hand to be at a certain distance from the surface of the skin to be made up, in particular the face.

The main facet may or may not be traversed by the longitudinal axis of the applicator member.
