Description

TECHNICAL FIELD [0001] The present invention relates to an applicator for applying a cosmetic, a makeup or a care product to an eyelash and / or an eyebrow. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

The present invention relates to an applicator for applying cosmetic, makeup or care products, for example mascara, to eyelashes and / or eyebrows.

The present disclosure also relates to devices comprising a product to be dispensed and having a container provided with a wiping member and an applicator.

Applicators whose core has a furrow with a V-shaped profile are known from application FR 2 918 547.

Application WO 2009/141098 discloses an applicator having annular application surfaces disposed on a core to form a spiral.

There is a need to further improve applicators for applying products, especially mascara, to eyelashes and / or eyebrows to enhance the performance of the product, more particularly to promote the formation of more abundantly loaded areas on the applicator member , Which allows rapid and abundant loading of eyelashes and / or eyebrows and easy application of makeup while maintaining the applicator easy to manufacture.

An applicator for applying a cosmetic, makeup or care product to eyelashes and / or eyebrows, in accordance with one of the aspects of the present invention, for the purpose of fulfilling the above object and its object, the applicator comprising a molded applicator member Wherein the applicator member comprises:

A core having two opposing longitudinal grooves extending along the longitudinal axis and rotating about the longitudinal axis when extending along the longitudinal axis,

- spikes supported by the core.

The present application allows for obtaining at least one zone on the applicator member, particularly along the grooves, which form a reservoir, the contents of which are not emptied during the extraction of the applicator, so that along the entire length of the core and after all the wiping It provides an excess product on the clothes. This excess product allows a large amount of satisfactory amount of product to be loaded from the first application to the eyelashes and / or eyebrows.

The arrangement of the grooves creates a twist around the core. The applicator according to the present invention is easy to manufacture because it is molded and the core of this applicator reproduces the appearance of a twisted brush with metal strands. In this application, the strands formed by molding rotate about each other and form opposing grooves. The present application allows, if desired, to create an array of bristles that is different from known applicators. During application of the make-up, the grooves are gradually emptied of the contents of these grooves, especially thanks to the lashes and / or eyebrows penetrating into these grooves. Thus, the eyelashes and / or eyebrows are suitably covered with the product, without the need for the user to re-introduce the applicator back into the container and frequently reload the applicator.

The shape and arrangement of spikes and grooves can be selected according to the desired makeup effect.

The depth of the grooves can be varied to adjust the level at which the product is loaded into the applicator after wiping.

The expression " the longitudinal axis of the core" indicates a line connecting all the centers of mass of the core section. The longitudinal axis may be a central axis or even an axis of symmetry with respect to the core, especially when the core has a cross section in the overall shape of a circular cross section or regular polygon. The longitudinal axis of the core may be straight or curved and may be included in a plane that may be a symmetrical plane with respect to some or even all of the cross sections of the core. Preferably, the longitudinal axis of the core is a straight line.

The term " spikes " refers to individual protruding elements intended to be associated with eyelashes and / or eyebrows.

Core and grooves

Preferably, each of the grooves is continuous along the longitudinal axis of the core without being interrupted along its entire length. In one variant, at least one groove is interrupted along a portion of its length.

The applicator member may not have any grooves along a portion of its length. Nevertheless, preferably, each groove extends substantially along the entire length of the portion of the core supporting the spikes, and in particular extends from the proximal end of the core to the distal end of the core.

Each groove may extend below the complete turn about the longitudinal axis of the core. Preferably, however, each groove extends more than one revolution about the longitudinal axis of the core, e.g., slightly more than two revolutions about the core.

Each groove preferably rotates in the same direction, for example around the longitudinal axis of the core in the clockwise direction, when viewed from the proximal end to the distal end of the core.

Opposing grooves preferably oppose each other at each point along the length of the core, preferably against the longitudinal axis of the core. These grooves may be symmetrical in cross section with respect to the longitudinal axis of the core.

The core advantageously has an overall shape of "8" having a cross section perpendicular to the longitudinal axis.

The grooves of the core may extend spirally about the longitudinal axis of the core. The expression " spiral extending " should be understood to mean that the grooves follow the path of the spiral around the longitudinal axis of the core.

The grooves preferably have a constant helical pitch along the longitudinal axis of the core, respectively. Opposing grooves advantageously have the same helical pitch.

The helical angle with respect to the longitudinal axis of the core may be between 30 ° and 60 °. This angle is preferably constant for the entire spiral.

In one variant, at least one groove of the core has a variable helical pitch along the longitudinal axis of the core.

The depth of the grooves can be from 0.075 mm to 1 mm, and even more preferably from 0.1 mm to 0.9 mm. The expression " depth of groove" represents the distance measured on the bottom of the groove and on a cross-sectional plane perpendicular to the longitudinal axis of the core between the lines tangential to the core and lying on the core at both sides of the groove.

The depth of the grooves of the core is advantageously constant along its entire length. In one variant, the depth of at least one groove of the core is variable along the longitudinal axis of the core.

The width of the grooves in the middle of the depths of the grooves may be between 0.1 mm and 1.5 mm, and more preferably between 0.15 mm and 0.8 mm.

Spikes

The cores and spikes may be formed of one and the same material or in one variant may be made of at least two different materials.

The core and / or spikes are preferably made of a thermoplastic material.

In some embodiments of the present disclosure, the spikes are fabricated by overmolding in the core.

The spikes are advantageously arranged on the applicator member in a plurality of linear longitudinal rows. The spikes may be arranged in circumferential rows, called crowns of spikes, each formed by spikes occupying one and the same axial position on the longitudinal axis of the core.

The spikes are such that the angle alpha ₁ is non-zero around the longitudinal axis of the core between the two consecutive crown of spikes, preferably half of the angular pitch beta between two consecutive spikes in the crown . ≪ / RTI >

In one variant, two consecutive first crown of spikes along the longitudinal axis of the core are identical, and two consecutive crown are arranged in each direction by one and the same non-zero angle < _{RTI ID} = 0.0 & Offset, and is preferably equal to one-half of the angular pitch [beta] between two consecutive spikes of the crown. The angle? ₂ is preferably equal to the angle? ₁ .

The spikes may be located in the grooves or outside the grooves of the core and may or may not follow the apparent movement of the cores obtained by the grooves.

At least one spike may extend from the core along a stretching axis perpendicular to the surface of the core at the point where the spike is attached to the core. Preferably, each of the spikes extends from the core along a stretching axis perpendicular to the surface of the core at the point where the spikes are attached to the core.

In one variant, the extension axis of the spikes forms an angle other than 90 degrees with the surface of the core at the point where the spikes are attached to the core. The expression " extension axis of the spike" refers to the axis passing through the centers of mass of the sections of the spike.

The height of the at least one spike measured from the core may be 0.5 mm to 3 mm, or even 0.75 mm to 2 mm. The expression " height of spike" refers to the distance measured along the extension axis of the spike between the free end of the spike and the base of the spike and is connected to the core through the base of the spike.

Preferably, the height of the spikes varies, for example, in a monotonous manner along the longitudinal axis of the core. In one variant, the height of the spikes is constant along the longitudinal axis of the core.

The spikes can have a flat cross-section, that is, the spikes have a cross-section measured at least in part on their height, perpendicular to the stretching direction with a long shape in a flat plane, i.e. a wider shape than a thick one. The flat plane of the spikes may form an angle of 60 [deg.] To 120 [deg.] With the longitudinal axis of the core, and is preferably perpendicular to the longitudinal axis of the core. In one variant, the flat plane of the spikes forms a zero angle with the longitudinal axis of the core.

Some spikes or even all spikes of the applicator may have a thickness of 0.3 mm to 0.85 mm or 0.5 mm to 0.75 mm. The expression " thickness of the spike" represents the maximum transverse dimension of the spike at a cross-section perpendicular to the stretching axis of the spike. This maximum cross-sectional dimension is particularly the diameter when the spike has a circular or semi-circular cross-section.

Spikes can have any shape. The spikes may have a cylindrical or tapered shape, in particular a conical, semi-conical, frusto-conical or pyramidal shape, in particular a hexagonal base. The spikes preferably have an asymmetric shape, each having a first surface, in particular a flat surface, and a second surface, for example a non-flat surface, in particular a round surface. In one variation, the spikes have an asymmetrical shape and an outwardly convex edge in the front view, and have a width that narrows over at least a portion of the height farther from the core and decreases toward the convex edge.

The cross-section of the spikes may have a substantially semicircular or semi-elliptical shape, which may be half-moon, or may also be, for example, hexagonal.

The at least one spike can be terminated with a rounded, particularly hemispherical, free end.

Spikes may differ from each other by at least one of shape, thickness, height, orientation, color, and / or material.

The free ends of the spikes of the applicator member define an envelope surface of the applicator member and the surrounding surface is in the form of a rotating cylinder, for example along at least a portion of its length, and in a variety Shape. The surrounding surface of the applicator member is advantageously rotationally symmetrical about the longitudinal axis of the core, and in particular has the overall shape of the peanut.

The encircling surface may have a substantially constant maximum transverse dimension along at least a portion of the length of the applicator member, particularly along more than half of the portion of the core supporting the spikes.

The encircling surface may also have a cross-section that varies along all or a portion of the length of the applicator member. The cross-section of the surrounding surface may have, for example, one or more extremes and, for example, at least one local minimum and two local maximums. The cross-section of the surrounding surface has a local minimum at a point corresponding somewhat to the middle of the visible length of the applicator member, for example, especially when the surrounding surface has the overall shape of the peanut.
