DEVICE FOR APPLYING A FLUID OR PASTY PRODUCT ONTO KERATIN FIBRES COMPRISING AN ORIENTABLE BRUSH
A device for applying a fluid or pasty product onto keratin fibres includes a longitudinal axis (XX), a rod extending about the longitudinal axis, a brush with a core of elongated shape, having two ends, and a series of spikes distributed over said core. The brush is mounted on a mounting end of the rod that is free to rotate about a pivot axis perpendicular to the longitudinal axis between an aligned position, in which the core extends along the longitudinal axis, and an inclined position, with the pivot axis being located at a middle section of the core located between the two ends of the core. The application device has means for indexing a position of the brush arranged in the vicinity of and around the pivot axis.
The invention relates to an applicator device for applying a fluid or pasty product to keratin fibers, comprising an orientable brush.
PRIOR ARTCommonly, applicator devices for applying a fluid or pasty product to keratin fibers, such as a mascara brush, have an elongate stem, at the end of which there is a brush that is in the continuation of the stem and is fixed so as not to be orientable with respect thereto. As a result, in order to make themselves up, a user of such a device is obliged to carry out more or less difficult hand movements in order to correctly orient the brush with respect to the eyelashes to be made up. In order to simplify the hand movements for making up the eyelashes, the document WO2018/115605, for instance, has proposed an applicator device having an orientable brush fitted at the end of the stern. However, such a device is complex in that the stern, which is hollow, has a coaxial sliding rod that makes it possible, with the aid of a toothed rack, to orient the brush located at the end of the stern, At the handle situated at the opposite end of the stern, the rod is put into action with the aid of an indexed pushbutton. The complexity of such an applicator device brings about high product costs and risks, as a result of the use and the quality of the pasty mascara products, of the rod getting stuck within the stem on account of the presence of the product.
It is therefore necessary to provide an applicator device that makes it possible to easily orient the brush situated at the end of the stern and is easy to manufacture and to use.
SUMMARY OF THE INVENTIONAn aim of the invention is to provide an applicator device for applying a fluid or pasty product to keratin fibers, comprising an orientable application brush that does not have the above drawbacks.
To this end, the invention provides an applicator device for applying a fluid or pasty product to keratin fibers, comprising a longitudinal axis, a stern extending along the longitudinal axis, a brush having a core of elongate shape, having two ends, and a series of spikes distributed over said core, the brush being fitted on a fitting end of the stern so as to be free to rotate about a pivot axis perpendicular to the longitudinal axis between an aligned position, in which the core extends along the longitudinal axis, and an inclined position, the pivot axis being situated in a middle portion of the core situated between the two ends of the core, the applicator device also having means for indexing a position of the brush that are arranged in the vicinity of and around the pivot axis.
Advantageously, but optionally, the applicator device according to the invention has at least one of the following technical features:
-
- the means for indexing a position of the brush comprise a series of indexing teeth;
- the series of indexing teeth is disposed in a circular arc about the pivot axis;
- the series of indexing teeth forms a toothed rack;
- the series of indexing teeth is provided in the middle portion of the core;
- the means for indexing a position of the brush comprise an indexing finger arranged so as to cooperate with the series of indexing teeth;
- the indexing finger is provided at the fitting end of the stem;
- with the fitting end of the stem having a U-shaped fitting fork for the brush, the indexing finger is provided at a bottom of the U of the fitting fork;
- the brush is fitted on the fitting end of the stem by being snap-fitted thereon;
- the stem has a set of spikes distributed at the fitting end of the stem; and,
- in the inclined position, the core of elongate shape is inclined with respect to the longitudinal axis by an angle of between 0 and 160°.
Further features and advantages of the invention will become apparent on reading the following description of an embodiment of the invention. In the appended drawings:
For greater clarity, identical or similar elements are provided with identical reference signs throughout the figures.
DETAILED DESCRIPTION OF AN EMBODIMENTWith reference to
With reference to
With reference to
The brush 3 has an elongate core 15, of axis X′X′, comprising two ends 13 and 18 between which the elongate core 15 has a middle portion 151. In the middle portion 151, the brush 3 has a pair of pegs 10 that protrude from a surface of the elongate core 15 along the pivot axis YY. Moreover, the brush 3 has means 12, 16, 17 for indexing a position of the brush 3 with respect to the stem 4, which are arranged in the vicinity of and around the pegs 10 and, consequently, in the vicinity of and around the pivot axis YY. In this case, the indexing means comprise a series of indexing teeth 16, of which there are 3 here. The series of indexing teeth 16 is disposed in a circular arc around the pivot axis YY. The series of indexing teeth 16 protrudes from the surface of the middle portion 151 in a direction substantially perpendicular to the pivot axis YY. In this case, for example, the series of indexing teeth 16 forms a toothed rack 12 which extends in a plane passing through the longitudinal axis X′X′ of the elongate core 15. In addition, the brush 3 comprises a series of spikes 14 distributed over at least a part of an outer surface of the elongate core 15, the series of spikes 14 protruding from the outer surface of the elongate core 15.
With additional reference to
At the fitting end 7 of the stern 4, there are also a set of spikes 71 that protrude from an outer surface of the stem 4 and are situated diametrically with respect to the abovementioned receiving housing 81. In an embodiment variant, these spikes 71 are not present, as is illustrated for example in
With reference to
With reference to
With reference to
It is apparent from the above that the use of an applicator device 1 according to the invention makes it possible to simply adapt the position of the brush 3 with respect to the stern 4, while allowing said brush 3 to be kept, with respect to the stem 4, in the inclined position chosen by the user from the values of the inclination angle α allowed by the series of indexing teeth 16 cooperating with the indexing finger 17. Such a structure of the applicator device 1 according to the invention makes it possible to adapt the latter to the user's hand movements for applying makeup in a simple and reliable manner; these hand movements for applying makeup then being more intuitive for the user. For example, when the brush 3 is in an inclined position with respect to the stern 4, in particular when the angle a is around 90°, the user does not need to change hands when they pass from one eye to the other when making up the eyelashes by carrying out an upward makeup application movement.
It should be noted, in addition, that once the applicator device 1 according to the invention is in a configuration in which the brush 3, 30 is inclined with respect to the stem 4, particular hand movements are not necessary before returning the applicator device 1 according to the invention into the reservoir 2 through the threaded opening 5 of said reservoir 2. This is because, while it is being put back, the brush 3 which is then in the indexed inclined position is introduced into the threaded opening 5 via its end 18, and then a simple rotational movement makes it possible to realign the axis X′X′ of the elongate core 15 with the axis XX of the stern 4 so as to make it possible to continue inserting the brush 3 into the reservoir 2 and then to tighten the handling handle 41 on the thread of the threaded opening 5. Similarly, while using the applicator device 1 according to the invention, the user can choose the inclination of the brush 3 with respect to the stem 4, via a simple rotational movement, before the end 18 is released from the threaded opening 5.
In an embodiment variant, the brush may be provided with spikes different than those that are illustrated in the figures, such as hooks or spikes of the petal type, etc.
Of course, it is possible to make numerous modifications to the invention without otherwise departing from its scope.
