DETAILED DESCRIPTION

FIGS.1and2illustrate an exemplary shaping system10according to the invention, configured to shape the application surface of an applicator on the basis of topographical data of at least a portion of a predefined region of the keratin materials of a user. This shaping operation makes it possible to match the application surface to the morphology of said predefined region for the application of a cosmetic composition.

In the example shown inFIGS.1and2, the shaping system10includes two parallel rows of four movable elements11, composed of actuating rods in this example. These movable elements each move only along an axis X, all in the same direction. Each movable element11is linked to a return element13. A cable14links each movable element11to an actuator12. To bring the movable element11closer to the support of the shaping system10along the axis X, the actuator12rotates in one direction such that the cable14is wound up and pulls on the movable element11, the return element13then being compressed. Conversely, to move the movable element11away, the actuator12rotates in one direction such that the cable14is unwound. The return element13relaxes and moves the movable element11away from the support of the shaping system10.

In the embodiment shown inFIG.1, a 3D camera makes it possible to acquire topographical data of a predefined region of the keratin materials of a user, for example the region of an eye or of a cheek. These data are measurements of positions in space. Thus, each item of data represents one point on the face for which the coordinates in space are known. The overall set of data allows the shape of the acquired region of the face to be reproduced.

In the example in question, the shaping system10is connected to a circuit board15allowing the topographical data from the prior acquisition operation to be processed. This processing operation makes it possible to determine the movement along the axis X to be applied to each movable element11such that the movable elements11are positioned so as to reproduce the inverse shape of the region acquired previously. Thus, the difference in height between two movable elements11advantageously corresponds to the difference in height between two points on the face for which the data have been acquired.

Once the movable elements11have been positioned on the basis of the topographical data of the region to be made up, in the example described, a membrane21, corresponding to the deformable portion of the applicator to be shaped, is placed over the shaping system10. The positioning of the movable elements11imposes a shape to the membrane; in particular, the inverse of the region to be made up. Thus, the shape of the applicator is adapted to the morphology of the user.

FIGS.3and4show an applicator20, the membrane21of which defines an application surface. This applicator includes movable elements22that impose a deformation to the membrane21of the applicator20. These movable elements22are provided with teeth220, associated with movable bolts25that allow the applicator to hold its shape.

An unlocking element24allows the movable bolts25to be removed from the teeth220. Once the bolts have been removed from the teeth220, the movable elements22return to their initial position and no longer impose the particular shape to the membrane21. The applicator may thus be reconfigured.

FIGS.5aand5billustrate the steps for shaping an applicator20. In the first step, illustrated inFIG.5a, the applicator20is placed on the shaping system10. Each movable element22, provided with teeth220, of the applicator20rests on a movable element11of the shaping system10.

In the second step, illustrated inFIG.5b, the actuators12change the positions of the movable elements11in accordance with the topographical data acquired previously, as described above. The change in the positions of the movable elements11of the shaping system results in a change in the positions of the movable elements22of the applicator, the application surface of which may then take the inverse shape of the region to be made up. The applicator is advantageously locked in this configuration by pushing the locking element.

To proceed with applying make-up, the membrane21is brought into contact with a cosmetic composition C, then the membrane21of the applicator20is pressed onto the region to be made up P in order to transfer the cosmetic composition C to the keratin materials. This last step is shown inFIG.11.

An exemplary applicator20that can be shaped by the shaping system10according to the invention is shown inFIG.9. This applicator includes a membrane21and movable elements22without teeth. In this example, to fix the applicator20, an adhesive material26, which hardens by crosslinking, is poured between the movable elements22, as illustrated inFIG.10. The shape of the applicator20is then fixed and cannot be reconfigured.

Example 1

In a first example of use, described with reference toFIG.8, the user uses the shaping system10according to the invention to give the inverse shape of the region to be made up to the application surface. Once the desired shape has been obtained, the user applies their make-up using the applicator.

In this embodiment, the shaping system10is produced with four stepper motors12. The movable elements11include rods of about 5 mm in diameter, 30 mm in length, and which are spaced apart by about 3 mm.

In a first step, the topographical data of the region to be made up on the user, for example an eyelid, are captured using a 3D scanner16.

These topographical data are transmitted to a computer server17that is configured to use the topographical data to calculate the positioning of the movable elements11, which are subsequently moved in accordance with the calculation performed.

A membrane21is then placed over the set of movable elements11, and it is crimped over the ends of the system10.

The computer server17may in particular provide the shaping system10with a morphology of the face in inverse mode, i.e. a complementary morphology of the shape of the face. The actuators12then move the movable elements11, and in so doing the membrane21takes the inverse shape of the portion of the face to be made up. The membrane21may then be used to apply make-up. For this, a layer of cosmetic composition, for example a layer of powder, is deposited on the application surface, and then brought into contact with the region to be made up.

To apply make-up, it is also possible to give a special shape to the membrane21before depositing a layer of cosmetic composition. In particular, the membrane21is transformed into a planar surface and it is brought into contact with a layer of cosmetic composition, and then the inverse shape of the region of keratin materials to be made up is given to the membrane21by placing it over the shaping system10, as described above. Next, the membrane21is brought into contact with the region of keratin materials to be made up.

The cosmetic composition may be a transferable print or a layer of powder, containing in particular pigments. The invention makes it possible in particular to produce patterns on the keratin materials in a straightforward manner.

This mode of use of the shaping system10is particularly suitable for a beauty salon or shop for example. Specifically, this use allows a plurality of customers to be made up one after the other using the same applicator20while giving a personalized shape to the application surface21, corresponding to each customer. Since the customers may return several times, in order for them to avoid having to go through a 3D acquisition operation on each visit, it is possible to store their morphologies and to index them by their name or any other identifier.

This mode of use is also applicable to a user who has a shaping system10according to the invention and an applicator20at home. In this case, the user may use the device to apply make up to several parts of the face. The device captures and stores the inverse 3D shape of each region of keratin materials to be made up, for example the eyelids, the cheeks, the lips or the nails. The user then uses a single applicator20, the shape of which they modify to adapt it to each region.

It is also possible to store the inverse 3D shapes of different people, for example different members of the same family, so that each of them may adapt the applicator20to their morphology.

It is also possible to use the device according to the invention in a hotel. For example, there may be a standard applicator20in each room and a shaping system10available from reception. Each client then has the possibility of coming to reception to adapt the applicator20to their morphology in order to apply their makeup.

Example 2

In another exemplary implementation, the user uses the shaping system10to adapt the shape of the application surface of a standard applicator20to their morphology. The shape of the surface of the applicator is therefore the inverse of the region to be made up on the user. The applicator20is then fixed so as to hold the personalized shape.

The applicator20may be fixed reversibly, in which case it may be reconfigured to return to a standard shape in order to be deformed anew. One possibility for fixing the applicator reversibly is to use a system of bolts25that are movable in relation to teeth220borne by the movable elements22of the applicator, as described above.

The applicator may also be fixed irreversibly, i.e. it can no longer take a shape other than that in which it has been fixed. One possibility for this is to pour an adhesive material which hardens by crosslinking, as described above.

Example 3

The following description is provided with reference toFIGS.6and7.

In this example, in order to allow the user to take up the cosmetic composition using an applicator in a special shape and then to change the shape thereof, they are provided with an applicator20, which has not been shaped, with a planar surface, and a first device20′ which is fixed and the shape of which is the inverse of the region of the keratin materials to be made up. The applicator20is for example an applicator which may be locked by means of a system of bolts that are movable in relation to teeth, as described above.

The user takes up the composition by pressing the application surface21of the applicator20onto a layer of cosmetic composition C. It is also possible to print a pattern directly onto the application surface21. This step is illustrated inFIG.6.

The user places the applicator20on the first device20′, the shape of which is the inverse of the region to be made up, as shown inFIG.7. By pressing, the device20′ prints its shape into the applicator20. The user then applies make-up with this applicator.

When the user wishes to apply make-up again, they reconfigure the applicator20by pulling the locking member24to give it a planar shape and go back to the first step.

It is also possible to envisage a step of cleaning the application surface in order to remove all trace of cosmetic composition for external application.

Preferably, the first device20′ is fixed to avoid mistakes. In particular, no locking member is provided and access to the actuating rods is prevented.

This embodiment is therefore economical because it does not require the user to buy a shaping system10or to make regular trips to a beauty salon. The invention also makes it possible to correctly transfer complex patterns to the keratin materials, which is not possible when the cosmetic composition is taken up with an applicator, the shape of which has already been adapted to the morphology of the region to be made up.

Alternatively, it is possible to make a mould of the inverse shape of the region to be made up and to use it to deform the applicator which is bearing the cosmetic composition, and which is initially in a special shape, for example planar. The mould may for example be made of plaster or of a photo-crosslinkable or reactive material.

In this case, the user makes the mould using a shaping system in a shop or salon. They also buy an unfixed applicator in a special shape. Using the mould and the applicator, they may simply take up a cosmetic composition and then adapt the shape of the applicator to their morphology.

The invention is not limited to the examples which have just been described.

Other types of movable elements and of application surfaces may be used, and other materials for producing them, or other means for moving the movable elements.
