Description

An applicator and a packaging and applicator device including such an applicator}

The present invention relates to cosmetic applicators comprising care products, and more particularly to applicators for applying substances on keratinous fibers, in particular eyelashes or eyebrows.

Conventional brushes for making up eyelashes or eyebrows comprise a metal core consisting of two twisted-together strands, with a bristle clamped between the strands. have. Such brushes are not suitable for passing through a microwave oven to modify the properties of the material, for example prior to application. In addition, in the case of certain compositions, bristle is too floppy, not suitable for smoothing the material on the eyelashes.

It is also known to make combs for making up eyelashes or eyebrows by molding plastic materials. The use of plastic material makes such combs suitable to pass through the microwave. In addition, it is possible to use other formulations by making a comb with teeth that are stiffer than the bristle of the brush. Nevertheless, this lack of flexibility can lead to lack of comfort during application.

European patent application EP 1 155 637 describes an applicator having an untwisted core, which includes a support providing a plurality of holes and bristles by imparting creep to the material of the support. After inserting into the hole, the bristle is fixed by deforming the holes.

There is a need to further facilitate the manufacture of an applicator comprising a non-metallic support and a bristle fitted to the support.

The present invention aims, in particular, to provide novel applicators for applying cosmetics on keratinous fibers, in particular on eyelashes or eyebrows.

And an applicator element comprising a.

Forming a plurality of rows of bristle by breaking the bundle of bristle makes it easier to manufacture the applicator at an industrially low cost, in particular by overmolding the support material on the bristle.

The present invention also provides an applicator that is simple and comfortable to use and allows the material to be well applied on the remarkably long and curved fibers to be treated.

The applicator element made according to the invention also makes it possible, if appropriate, to use a microwave oven for heating the material for application, while still providing the advantages of a mascara brush, especially in terms of comfort during application. .

The applicator may have a bristle attached thereto, i.e., prepared in a previous step apart from the applicator manufacturing process and implanted during the manufacturing process of the support or after the support is manufactured.

The first row of bristle may have a bristle number substantially equal to the total number of bristols of the second and third rows. Optionally, the second and third rows of bristle may have substantially the same number of bristle.

The first row of bristle may extend out of the support, but in a variant, the first row of bristle need not protrude out of the support.

Each of the second and third rows of Bristol may constitute a series of tufts leaving the support through respective orifices.

The first row may comprise a substantially continuous sheet or a series of tufts of bristle leaving the support through distinct holes.

The tufts of bristle may be constituted by 2 to 200 bristle, for example, preferably by 4 to 100 bristle, more preferably 5 to 50 bristle.

To form the second and third rows, the bundle of bristle may split inside or outside of the support.

The second and third rows of Bristol may extend from the same plane of the support, in particular a plane perpendicular to the intermediate plane, with respect to a separation plane comprising the longitudinal axis of the support, the first row Protrudes from the opposite side.

The bristle may be fixed on the support by a method other than overmolding the support material on the bristle. For example, the bristle may be fixed to the support by local melting of the material.

The bristle may be made from the same or a different material as the material constituting the support.

The support can be made in a variety of forms, and in particular can be made with at least one tooth row. They can be made from the same material as the support, or in a variant they can be made from other materials, for example by molding by dual injection of the material. This may in particular be made from a material which is more flexible than the material constituting the support portion bearing the bristle.

In a plane perpendicular to its longitudinal axis, the major dimension of the support can be, for example, 5 millimeters (mm) or less.

If the second and third rows of bristle comprise a series of tufts of bristle, the tufts of bristle in the second row are in the third row along the longitudinal axis of the support. It may be arranged at substantially the same level as the tufts of Bristol.

In a variant, the tufts of bristle in the second row may be axially off with respect to the tufts of bristle in the third row. In this case, the applicator may comprise a series of bristle tufts extending alternately along two diverging directions.

The applicator may comprise tufts of bristle, each obtained by splitting the bundle of bristols which are opened through openings located respectively in two opposite sides of the support, or in the variant respectively the same side. The openings may be arranged or arranged in a staggered form, for example.

If the support is made to have it, it can be arranged in two rows of bristle, for example at least one row extending between the second and third rows.

The longitudinal axis of the support may be straight, or in a variant, bent, in particular in the form of a circular arc portion substantially coincident with the radius of the eyelid in the eyelash root.

The apparent length of the bristol in one row may vary at least along the longitudinal axis of the support, and in particular may vary continuously through a single extreme value, for example a maximum or minimum value, Alternatively, the sheath surface defined by the free ends of the bristle when viewed from the side may be changed periodically to provide undulation along the longitudinal axis of the support.

The applicator may comprise holes, through which the bristle leaves the support, the holes providing axes perpendicular to the longitudinal axis of the support.

In a variant, the holes alternate of the support such that, when viewed from the side, the bristle intersects, for example toward its distal end and its proximal end. It is possible to provide axes which are obliquely oriented with respect to the longitudinal axis.

The material of the support can be a rigid, semi-rigid plastic material, or an elastomer.

In that other aspect, the present invention also provides:

At least three rows of bristol; And

A support holding the bristle, overmolded above the bristle

It provides an applicator comprising a.

The invention also provides a packaging and applicator device comprising an applicator providing at least one of the above defined embodiments.

The apparatus may comprise a receiver comprising a material to be applied and a wiper member for wiping the applicator element when the applicator element leaves the receiver. The applicator element may be secured at one end of the stem, the other end of the bag being secured to the handle member, which also constitutes a cap for sealing the receiver.

The invention can be better understood by reading the following detailed description of the non-limiting embodiments and referring to the accompanying drawings.

The packaging and applicator device 1 shown in FIG. 1 comprises a receiver 2 comprising a substance P for application to the eyelashes or eyebrows, for example mascara, and an applicator element 5 at the bottom end thereof. And an applicator (3) comprising a bag (4) with a handle member (6), which at its opposite end also functions to seal the receiver (2). The receiver has a neck 7 with an external thread to enable the handle member 6 to be screwed on it.

The substance P may be for coloring the eyelashes and / or extending them and / or curling them. The material P may also have a treatment effect.

In the case where the bag 4 and the applicator element 5 leave the receiver, a wiper member 8 is fixed inside the neck 6 to wipe them off. The wiper member 8 has, for example, a flexible lip 9 defining a circular hole of a diameter substantially corresponding to the diameter of the bag 4.

Naturally, the present invention is not limited to using a specific wiper member, for example comprising a foam block, and / or one or more optionally locked slots. Wiper members may be used as well.

In the example shown, the bag 4 is straight, but it may be bent without departing from the scope of the invention.

In addition, the bag 4 is shown to be fixed relative to the handle member 6, but for example articulated connection means, in particular ball-and-socket joints. by means of a joint).

The applicator element 5 comprises a support 15 made of plastic material, which extends along the longitudinal axis X, which is straight in the example shown and the length of the bag 4. Coincides with the direction axis.

The support 15 holds a bundle 20 of Bristol, which in the example shown projects from one side of the support 15 in the form of a first row 50, and the second and third rows. In the form of 30 and 40 it is divided into two parts protruding from the opposite side of the support 15.

In the example shown, the support 15 is overmolded onto the bundle 20 of Bristol, but in a variant the support 15 can be produced separately, after which the bristle is put in place. For example, it can be assembled to the support 15 by locally melting the material.

In the example shown, the rows 30 and 40 protrude through openings located respectively in two opposing faces 31 and 41 of the support 15. In FIG. 2, it can be seen that the rows 30 and 40 are located on the same side of the separating plane S comprising the axis X, while the first row 10 is located on the opposite side. have.

Each row 30 or 40 of Bristol extends from the support 15 through a single opening of oblong shape extending parallel to axis X, or each opening, as in the example described, These can extend from the support 15 through a series of individual openings 32 and 42 which allow the tuft of the bristle to protrude.

The number of bristle in each row 30 or 40 in the illustrated example corresponds to half of the number of bristle in row 50, but the applicator element may be manufactured differently without departing from the scope of the present invention. In particular, one of the rows 30 and 40 may have significantly more bristle than the other row, in other words the bundle of bristle may split at a ratio other than 50/50.

In the example shown, the bristle 50 of the first row has a length other than zero, but the bristle of the row 50 is substantially zero as shown in FIG. 3 without departing from the scope of the present invention. It may have a phosphorus length, and the bristle of this row 50 is shaved off, for example after the support 15 is molded. Even the bristle of the first row 50 does not need to extend out of the support.

The support 15 may be manufactured to have a different shape than that shown in FIGS. 1 and 2, in particular it extends between the rows 30 and 40 of Bristol, as shown in FIGS. 4 and 5. It may have at least one row of teeth 60.

4 shows that the support 15 can be made to have a distal end 16 at one end so that it can be inserted into the bag 4. In a variant, the applicator element may be manufactured integrally with the bag 4 by molding the material, regardless of its shape and how the bristle is implanted.

The bundle of bristle 20 may split inside the support, as shown in FIGS. 2, 3, and 5, or outside of the support 15, in particular thereof, as shown in FIG. 6. It may crack near the outer surface.

The example of FIG. 7 differs from that of FIG. 6 in that the length of the bristle in the first row 50 is substantially zero.

In this figure, it is also shown that the support can provide various shapes other than those shown in FIGS. 2 and 3 in cross section, in particular the support can provide for example a substantially circular cross section. It is shown that it can.

In the example of FIG. 8, the bristle of the rows 30 and 40 meets outside of the support 15.

The rows 30 and 40 may extend among the spreading planes Y and Z, which planes may be parallel to the longitudinal axis X when the axis is straight.

As can be seen in FIG. 2, planes Y and Z can be symmetric about the symmetric intermediate plane M with respect to the support 15. The axis X can be included in the intermediate plane M.

In a variant, the planes Y and Z need not be arranged symmetrically with respect to the intermediate plane M of the support 15, as can be seen in FIG. 9.

The angle α between the planes Y and Z may, for example, be in the range of 3 ° to 90 °, for example close to 40 °.

In the examples described above, the applicator element 5 has three bristle rows 30, 40 and 50, but without exceeding the scope of the invention, there are more than three applicator elements. It is also possible to have the rows of Bristol, for example four rows of Bristol.
