Technical Field

The invention relates to an applicator device for applying a fluid or pasty product onto keratin fibres or onto the epidermis. In particular, the present invention relates to an applicator device for applying a skin care product, makeup or care product to the hair, eyelashes, eyebrows, skin or lips.

Background

Currently, there are applicator devices for applying a product of the fluid or pasty type onto keratin fibres, such as mascara brushes, which comprise a central core of elongated shape extending along a longitudinal axis and at least one row of elongated spikes comprising a first end embedded in the core and a free second end. Typically, the spike and the core are formed as a single piece by molding, substantially integral with one another. Document FR 2937514, for example, describes such an applicator device. A disadvantage of this type of embodiment is that the spikes are arranged in such a way that the product to be applied is held at the embedded end, close to the core, in particular after passage of the wiper. Thus, the product to be applied is mostly located near the core of the brush of the applicator device, away from the free ends of the spikes. This is because, on passing through the wiper, the latter is completely wiped, removing the product to be applied. For example, in the case of keratin fibres, this results in the user applying a certain force to ensure that the keratin fibres pass between the spikes, thus being as close as possible to the core of the applicator device, in order to correctly coat the product. There is also a risk of spike pricks, such as spike pricks to the eyelids when applying makeup to the eyelashes, spike pricks to the skin for long periods when treating the eyebrows, spike pricks to the lips or scalp, and the like.

One solution to this problem is to provide an applicator device in which the core of the brush has an enlarged diameter. In order to pass the brush through the wiper, the diameter of the latter is therefore increased. A disadvantage of this solution is that it will greatly increase the load of the product to be applied, which load will largely remain in the area of the core once the wiper passes. During use, such applicator devices leave unsightly pieces of product on the keratin fibers so treated.

Disclosure of Invention

It is an object of the present invention to provide an applicator device for applying a fluid or pasty product which enables an optimal application of the product while giving a more comfortable feeling to its user.

To this end, the invention provides an applicator device for applying a fluid or pasty product onto keratin fibres or the skin (epidermis), comprising an elongated core extending along a longitudinal axis X and having a longitudinal cylindrical shape, a plurality of spikes distributed on the core, each spike extending from one end anchored in the core to a free end and being substantially integral with the core, each spike having, at its free end, means for collecting and retaining a quantity of the fluid or pasty product.

This configuration of the spikes therefore makes it possible to keep the distal end holding a certain amount of product to be applied to the keratin fibres without having to make said keratin fibres slide completely between the spikes. This provides the user with optimal comfort while ensuring optimal application of the product on the keratin fibres.

Advantageously, but optionally, the applicator device according to the invention has at least one of the following technical features:

the collecting and retaining means comprise a first curved portion at the free end of the spike;

each spike has a secondary extension projecting from the spike at a distance from the free end;

the collecting and retaining means comprise a second curved portion formed by the secondary extension;

the collecting and retaining means further comprise lateral spikes projecting from each spike;

-the lateral stab is located at one end of the first curved portion;

the lateral spine is located between and at a distance from the ends of the first curved portions;

-the collecting and retaining means partially define a reservoir intended to receive the quantity of fluid or pasty product;

and

each spike has, at its anchoring end, second means for collecting and retaining a quantity of fluid or pasty product at a distance from its anchoring end.

Detailed Description

With reference to fig. 1, one embodiment of an applicator device 1 will be described. In this case, the applicator device 1 according to the invention is a mascara brush. In this case, it comprises a core 2 extending longitudinally along a longitudinal axis X. The core 2 may have a constant or non-constant cross-section along its length. In the most common embodiments, the cross-section is constant or gradually decreases from the proximal end engaged with the tube and/or the gripping handle to the distal free end. Typically, the core 2 has an overall cylindrical shape, preferably with its axis of rotation being the longitudinal axis X. Thus, the cross-section of the core 2 may have a circular, polygonal, elliptical or other shape. It may be axisymmetric. The core 2 may be solid or hollow. The skilled person will select the most suitable core according to economic and/or technical constraints.

Furthermore, the applicator device 1 according to the invention comprises a plurality of spikes 10 distributed over the core 2. The spikes 10 protrude from the outer circumferential surface of the core 2. The spike 10 is, for example, substantially integral with the core 2. In particular, the spike 10 is obtained by moulding together with the core 2. In this case, as shown, the spikes 10 are distributed in adjacent rows extending longitudinally in pairs parallel to the longitudinal axis X. The spikes 10 of the same row extend parallel to one another from the core 2 in the same manner according to the same orientation. In this case, when considering two adjacent rows, the spikes 10 of one of the adjacent rows are oriented differently from the spikes 10 of the other of the adjacent rows, for example by 180 ° as shown in fig. 1. In one variant, the orientation is 90 °.

With reference to fig. 3 and 4, a first embodiment of a spike 110 for use in an applicator device according to the present invention will be described. The spike 110 according to the present invention has an anchoring end 11 and a free end 12. The anchoring end 11 is connected to the core 2 of the applicator device according to the invention. The spikes 110 thus extend from the anchoring end 11 to the free end 12, in this case generally in a plane which is the lamina in fig. 3. From the anchoring end 11, as shown, the spike 110 according to the invention has a first body portion 16 curved in a first direction, then a second body portion 18 curved in the opposite direction, and finally ends with a free end 12. This gives the reverse "S" shape of the body of the spike 110 according to the present invention, as shown in fig. 3. The first body portion 16 is connected to the second body portion 18 at an end 20 common to both body portions. The curved shape of the second body portion 18 forms a first curved portion at the free end 12.

In addition, the spike 110 has a secondary extension 17 that projects from the spike 110 at the common end 20 of the two body portions 16, 18. In this case, this secondary extension extends in the plane of the spike 110. It forms a second curved portion which extends facing the first curved portion 18 and has a curvature opposite to that of the first curved portion. The first curved portion and the second curved portion thus form collecting and retaining means and partially delimit a reservoir 14 intended to receive a quantity of fluid or pasty product. Thus, the first curved portion formed by the second body portion 18 makes it possible to protect a quantity of fluid or pasty product received in the reservoir 14 during use of the applicator device 1 according to the invention, in particular when passing through the wiper of this device 1 according to the invention: the spike is not cleared of the quantity of product.

Furthermore, the spike 110 has second means 13, 15 and 16 for collecting and retaining a quantity of fluid or pasty product. These second collecting and retaining means are located at the anchoring end 11 of the spike 110 at a distance therefrom, while being below the above-mentioned collecting and retaining means located at the free end 12 of the spike 110. In this case, the second collecting and retaining means have a first curved portion formed by the first body portion 16 of the spike 110 and a second curved portion formed by the second secondary extension 15, the second secondary extension 15 extending towards the first curved portion formed by the first body portion 16 and having a curvature opposite to that of this first curved portion. The secondary extension 15 protrudes from the spike 110 at the lower end 21 of the first body portion 16, in this case this second secondary extension extends in the plane of the spike 110. Thus, the first body portion and the second secondary extension 15 partially define a second reservoir 13 intended to receive a quantity of fluid or pasty product. Thus, the reservoir 14 is located above the second reservoir 13 in the direction of extension of the spike 110.

With reference to fig. 5, a spike 210 as described above for a variant embodiment of an applicator device according to the present invention will be described. The spike 210 of this variation has a first body portion 216 that curves in a first direction from the anchoring end 11 to the free end 12, followed by a second body portion 218 that curves in the opposite direction. Furthermore, the spike 210 has a side 219 that extends over the entire height of the spike 210 and bears on the circle C. The circle C lies in a plane perpendicular to the longitudinal axis X, the intersection of the longitudinal axis X with the plane of the circle C lying on the circle C. The configuration of such spike-supporting faces of the circle C is described in detail in document FR 2937514, to which reference may be made for more comprehensive information.

Fig. 2 shows an applicator device 3 according to the invention with rows of spikes 210.

With reference to fig. 6 to 8, a second embodiment of a spike 310 for an applicator device according to the present invention will be described. Spike 310 is similar in structure to spike 110. Spike 310 differs from spike 110 in that in this case the collecting and retaining means also has two lateral spikes 19 protruding from spike 310. In this case, two lateral spikes 19 extend on either side of the plane in which the spike 310 lies. Two lateral spurs 19 are implanted at the common end 20 and are in this case upwardly inclined. The lateral spikes 19 also partially define the reservoir 14. In a variant embodiment, the spike 310 has only one lateral spike 19. In another variant embodiment, one or more lateral spikes 19 extend substantially horizontally.

Fig. 9 shows an applicator device 4 according to the invention with a row of spikes 310 and a variant embodiment of a row of spikes 410, which will now be described briefly.

Fig. 10 and 11 show a third embodiment of a spike 410 for an applicator device according to the present invention. Spike 410 is a variation of spike 310 described above. Unlike it, it has a single short lateral spike 419 extending substantially horizontally. In a modified embodiment, the lateral barbs 419 are similar to the lateral barbs 19 of the previous embodiment of spike 310.

Fig. 12 shows an applicator device 5 according to the invention with a row of spikes 110 and a variant embodiment of a row of spikes 410. Fig. 13 shows an applicator device 6 according to the invention with differently arranged rows of spikes 410 and rows of spikes 110. Other types of spikes according to the present invention can be used and associated.

Fig. 14-16 show a fourth embodiment of a spike 510 for an applicator device according to the present invention. The spike 510 differs from the spike 110 described above in that it has a lateral spine 519 projecting from the second body portion 518 of the spike 510, specifically a distance from the free end 12 and the common end 20, particularly substantially midway between these two ends. The lateral spine 519 extends substantially horizontally and in the direction of the reservoir 14. To maintain some flexibility of the second body portion 518 upon implantation of the lateral spine 519, a notch 520 is provided in the thickness of the portion 518 in line with the lateral spine 519.

In a variant embodiment, a spike 610 for an applicator device according to the present invention is shown in fig. 17. Spike 610 differs from previous spike 510 in that lateral spine 619 is thin and protrudes from the spike in a plane that is substantially horizontal and perpendicular to spike 610 in a similar manner as lateral spine 419 of spike 410 described above. Due to the thinness and implantation of the lateral spine 619, it is no longer necessary to provide a notch in the thickness of the second body portion 18.

Fig. 18-20 show a fifth embodiment of a spike 710 for an applicator device according to the present invention. This is a modified embodiment of the spike 110 described above. The spike 710 differs from the spike 110 in that the secondary extensions 715 and 717 have different dimensions than the secondary extensions 15 and 17, respectively. In particular, the secondary extensions 717 and 715 are longer and therefore enable the collecting and retaining device to accommodate products with low viscosity and higher flowability.

It should be noted that in the above described embodiments, the lateral spikes as part of the collecting and retaining means also make it possible to partially define the reservoir 14 and improve the intake and retention of the fluid or pasty product.

Similarly, a lateral prick, identical to that described above and being part of the second collecting and retaining means, may be provided at the second reservoir 13.

Generally, regardless of the embodiment of the applicator device according to the invention, at least the core 2 and the spike are substantially integrally formed with each other, thereby forming a one-piece component. The core and spikes are made of one or more thermoplastic, thermoplastic elastomer or vulcanizable material types of materials having different physical properties. Furthermore, the core and the spikes are obtained by means of a moulding process or an additive manufacturing process, for example of the stereolithography or three-dimensional printing type.

It will be apparent that many modifications can be made to the invention without departing from its scope.
