[0347] FIGS. 1A and 1B represent an example of an assembly according to the invention comprising a device (1) and a cosmetic composition (6) for cosmetic treatment of eyelashes.

[0348] The device (1) comprises a mould (2) which has two parts (2a) and (2b). The mould (2) preferably comprises an elastomeric material. The two parts (2a) and (2b) of the mould (2) each have a thickness e of approximately 2 mm for example.

[0349] The two parts (2a) and (2b) of the mould (2) comprise imprints (4), in the form of grooves of elongated shape. Each part (2a, 2b) comprises, for example, as illustrated, 17 imprints (4), for example of width l of approximately 0.5 mm, of length L of approximately 2.5 cm and of approximately semicircular cross section. The imprints (4) of each part (2a, 2b) of the mould (2) are preferably substantially parallel to one another. The imprints are also, preferably as illustrated, evenly spaced out, according to a step p of 1.5 mm, centre to centre.

[0350] The device (1) comprises two jaws (3a) and (3b) which carry respectively the mould parts (2a) and (2b).

[0351] The two parts of the mould (2) and the jaws (3a) and (3b) may have additional reliefs, so as to be able to accurately place the two parts (2a, 2b) of the mould (2) on each jaw (3a, 3b).

[0352] The lower jaw (3b) comprises, in the example under consideration, a temperature-controlled heating element (30).

[0353] The lower jaw (3b) is fixed, whereas the upper jaw (3a) slides vertically by means of a guidance system (80).

[0354] When the jaws (3a) and (3b) are closed against one another, as represented in FIG. 1A, cavities (5) are formed by virtue of the imprints (4), which are superimposed in pairs.

[0355] In the example under consideration, 17 cavities of elongated shape, having a width l of approximately 0.5 mm, a length L of approximately 2.5 cm and an approximately circular cross section, which are substantially parallel to one another and evenly spaced out, according to a step p of 1.5 mm, centre to centre, are thus created.

[0356] The cavities (5) are closed on the sides and open out to the exterior, on the side where the eyelashes are introduced, via a front opening through which the eyelashes are introduced. The cavities are closed at their rear end.

[0357] To use the device (1), the cosmetic composition (6) is, for example, placed in imprints (4) of the part (2b) of the mould (2), mounted on the lower jaw, before introduction of the eyelashes. The composition (6) is a composition as previously described.

[0358] The eyelashes are introduced into the imprints (4) of the mould (2) of the device (1) in its open form (FIG. 1B), then the jaws (3a, 3b) are closed so as to hold the eyelashes in the cavities (5).

[0359] The heating element (30) brings the composition (6) to a temperature above 45° C., such that the composition (6) solidifies via the reorganization, or even the aggregation, of the particles dispersed in the liquid medium, and that it takes the shape of the imprints (4). The moulding of the composition onto the eyelashes is carried out in situ in the cavities (5) of the mould (2).

[0360] Then, the heating element (30) stops heating the composition and said composition is left to cool.

[0361] The jaws (3a, 3b) are opened and the eyelashes are withdrawn when the temperature of the composition (6) has come back down. The device (1) can be produced such that the closing of the jaws (3a) and (3b) automatically triggers the heating of the composition (6), and so that the heating is automatically stopped when the desired temperature is reached.

[0362] The opening of the jaws (3a) and (3b) can take place automatically, as appropriate. As a variant, a sound or light signal can indicate that the jaws can be opened.

[0363] FIGS. 2 and 3 represent more particularly the part (2b) of the mould (2) of FIGS. 1A and 1B.

[0364] It is seen that the part (2b) can be curved along the longitudinal direction M of the imprints (4), in order to reproduce the curved shape of the eyelashes, the radius of curvature preferably being between 15 and 25 mm.

[0365] The edge of the part (2b) intended to come into contact with the eyelid may have a rounded shape, concave towards the exterior, with a radius of curvature of preferably between 15 and 25 mm.

[0366] The device (1) may, according to one implementation variant of the invention, be in the form of a clamp, as represented in FIGS. 4A and 4B.

[0367] Like the device represented in FIGS. 1A and 1B, this device in the form of a clamp comprises a mould (2) in two parts (2a) and (2b). The mould (2) preferably comprises an elastomeric material. The two parts (2a) and (2b) of the mould (2) each have, for example, a thickness e of approximately 2 mm. The two parts (2a) and (2b) of the mould (2) comprise imprints (4), in the form of grooves of elongated shape. The device (1) comprises two jaws (3a) and (3b) which carry respectively the mould parts (2a) and (2b).

[0368] Each part (2a, 2b) comprises, for example, 15 imprints (4), for example having a width 1 of approximately 0.5 mm, a length L of approximately 2.5 cm, and a decreasing semicircular cross section so as to give the eyelashes, once moulded with the composition (6), a tapered appearance. The imprints (4) of each part (2a, 2b) of the mould (2) are preferably, as illustrated, substantially parallel to one another. The imprints are evenly spaced out, according to a step p of 1.5 mm, centre to centre.

[0369] The mould (2a, 2b) may have a radius of curvature along the direction M of FIG. 4B of between 15 and 25 mm in order to follow the shape of the eyelashes. The edge of the part (2b) intended to come into contact with the eyelid may have a rounded shape, concave towards the exterior, with a radius of curvature of preferably between 15 and 25 mm.

[0370] The edge of the jaws (3a, 3b) and of the mould (2a, 2b) intended to come into contact with the eyelid may have a rounded shape, concave towards the exterior, in particular circular, the edge of the eyelid describing, to a first approximation, an arc of a circle.

[0371] When the jaws are closed against one another, as represented in FIG. 4A, cavities (5) are formed by virtue of the imprints (4), which are superimposed in pairs. 15 cavities (5) of elongated shape, having a width 1 of approximately 0.5 mm, a length L of approximately 2.5 cm and a circular cross section of decreasing diameter as the distance from the opening for introducing the eyelashes increases, which are substantially parallel to one another and evenly spaced out, according to a step p of 1.5 mm, centre to centre, are thus, for example, created. The cavities (5) are closed on the sides and open out to the exterior, on the front side where the eyelashes are introduced, via a circular opening through which the eyelashes are introduced. The cavities are closed at their rear end.

[0372] The device (1) in the form of a clamp may comprise, as illustrated, two housings (20a, 20b) into which fingers of one hand, for example the thumb and the index finger, can be introduced so as to move the two jaws (3a, 3b) apart, in order to make it possible to introduce the eyelashes between them and to close them on said eyelashes.

[0373] The cosmetic composition (6) to be moulded is placed in imprints (4) of the part (2b) of the mould (2) before introduction of the eyelashes. The composition (6) is a composition as previously described.

[0374] An independent oven, not represented, can be used to bring the composition to the desired temperature, before introduction of the eyelashes into the imprints (4) of the mould. The housings (20a, 20b) preferably remain cold, the heating preferably taking place by radiative transfer on the faces of the mould having the imprints.

[0375] The cavity of the oven may have a parallelepipedal shape, for example an approximately 10 cm-sided parallelepipedal shape. In addition to its heating function, the oven can also make it possible to present the jaws in such a way that the user can seize them directly between the thumb and index finger, in a single action. In particular, it is possible to use portable clamps of which the internal faces are placed in front of the heat sources and the external faces bear grasping rings adjusted to the shape of the fingers.

[0376] The surfaces carrying the composition can, for example, be heated in the range 50° C.-80° C. The oven can be powered by a low-voltage power source.

[0377] The heating temperature can be adjustable by the user. A casing can enable a set temperature to be displayed. The heating power can be about 5 W for example.

[0378] When the composition is at the desired temperature, the user's thumb and index finger are introduced into the housings (20a and 20b), then the device (1) is brought into proximity to the eyelashes and the latter are introduced into the imprints (4) of the mould (2) of the device (1) in its open form (FIG. 4B), then the jaws (3a, 3b) are closed so as to hold the eyelashes in the cavities (5).

[0379] The moulding is carried out in situ in the cavity or cavities (5) of the mould (2).

[0380] Next, the jaws (3a, 3b) are opened and the eyelashes are withdrawn when the temperature of the composition (6) has come back down.

[0381] The device (1) in the form of a clamp may be devoid of a system for guiding the movement of one jaw relative to the other, as represented in FIGS. 5A and 5B. This device has two housings (20a, 20b) for the fingers, like the example previously described.

[0382] Only one of the parts can have imprints, which is particularly advantageous for a device (1) devoid of a guidance system, since the bringing together of the two parts of the mould does not need to be carried out very accurately.

[0383] By way of example, represented in FIG. 6A is a device (1) in which the part (2a) of the mould (2) may be smooth and the part (2b) may comprise semicircular imprints (4).

[0384] Moreover, each cavity (5) may have an elongated shape which does not reproduce the curvature of the eyelash(es) introduced, it being possible in particular for the cavity to be non-curved along its longitudinal direction, having, for example, a rectilinear longitudinal axis.

[0385] The device (1) in the form of a clamp may comprise a guidance system, for example in the form of reliefs having complementary shapes, which brings the jaws (3a, 3b) into position so that the two parts of the mould (2a, 2b) accurately correspond to one another. The device (1) in the form of a clamp may thus comprise, for example, a male and female cone guidance system.

[0386] The device (1) in the form of a clamp may comprise a guidance system of film hinge type or other form of articulation (40), as represented in FIGS. 7A and 7B, such that the jaws can be moved together by a pivoting movement with respect to one another.

[0387] Each cavity formed by the superimposition of two imprints may have a rectilinear longitudinal axis. The front edges of the jaws (3a, 3b) intended to come into contact with the eyelid may have a circular shape, as illustrated.

[0388] During the use of the device (1), the angle α made by the plane of moulding with the horizontal may be zero or non-zero, in particular between 20° and 40°, as illustrated in FIG. 8. Inclining the plane of the moulds makes it possible to fix the curvature of the edge coming into contact with the eyelid as close as possible to the curvature of the eyelid itself.

[0389] The hinge (40) may comprise one or more springs (50) as represented in FIG. 9, which assist the opening movement for example.

[0390] The device (1) in the form of a clamp may comprise a single housing (20a) for receiving a finger, as illustrated in FIG. 10, or two housings, as previously described.

[0391] It may be possible for the housing(s) (20a, 20b) to be oriented rotationally, which enables an adjustment according to the angle between the user's thumb and index finger. They may be positionable, where appropriate, at various points (60a), (60b) or (60c), depending on the desired distance between the fingers and the face of the user, as illustrated in FIG. 8.

[0392] The mould (2a, 2b) may be integrated into the jaws (3a, 3b). The device (1) in the form of a clamp may then be made of a flexible material of silicone type for example, in order to facilitate demoulding.

[0393] The mould may also be made of a flexible material of silicone type with the inclusion of a rigid frame. The housing(s) (20a, 20b) may be made of a rigid material, in order to improve the holding of the clamps in place and the overall shape of the mould, while facilitating demoulding.

[0394] It is possible for the mould (2a, 2b) not to be integrated into the jaws (3a, 3b), the jaws carrying the mould, which is then added to the jaws. The mould may be flexible and held on the jaws for example by adherence or by matching shapes, for example by click-fastening and/or sliding attachment. The jaws are then preferably rigid.

[0395] The mould (2a, 2b) may or may not be disposable. The jaws (3a, 3b) may or may not be reusable.

[0396] The composition (6) may be present within the mould before use of the device (1), in the part (2a), the part (2b) or in both parts. The loading of the mould with composition may be carried out prior to the use of the device, for example using a metering device.

[0397] The device in the form of a clamp has the advantage of being light, of allowing the user to precisely perceive the stresses applied, to the eyelid, during the operations, of creating a very small visual eclipse allowing optimal vision for the user, and of being easy to use.

[0398] The device (1), whether or not it is in the form of a clamp, may comprise a system which facilitates demoulding, for instance a set of small blades (10) which deform the mould, for example when moved relative to said mould in the direction of the imprints (4), as illustrated in FIGS. 1A and 11B.

[0399] The mould (2) may also comprise, as illustrated in FIG. 12, reliefs (9) between two imprints (4) intended to form two cavities, so as to cut any bridges of composition.

[0400] The device (1) may comprise blades (11) which serve to cut any bridges of composition between two cavities, as illustrated in FIG. 13.

[0401] The blades (11) are, for example, retracted within the part of the mould (2a) before closing thereof, and tend to advance upon closing of the mould. The blades (11) are, for example, interlinked with a support (111) which is mobile relative to the part (2a).

[0402] As a variant, the material of the part (2a) is elastomeric and overmoulded on the blades (11), which can push on the bridges of composition extending between the imprints (4) by virtue of the deformability of the material with which the part (2a) is made.

[0403] Other systems can be further used for cutting the bridges, for example a system which makes it possible to send compressed air via slits located between the imprints or a heating element.

[0404] The composition (6) can make it possible to attach an additional fibre (12) to an eyelash (7), with or without axial overlap between the eyelash and the additional fibre, as illustrated respectively in FIGS. 14A and 14B. The eyelash may be on the additional fibre if the additional fibre is in a cavity of the lower mould part, or vice versa, if the additional fibres are in cavities of the upper mould part. In practice, the additional fibres may also be next to the eyelashes depending on the organization caused by the pressure of the two parts of the mould.

[0405] The additional fibres may in particular be false eyelashes.

[0406] The additional fibres (12) may be placed on hold in the imprints (4) of the mould (2) (FIG. 15A). The composition (6) may then be applied to the ends of the additional fibres (12) and the eyelashes (7) introduced into the imprints (4) of the mould (2) and brought into contact with the composition (6) (FIG. 15B).

[0407] The cavities (5) may, according to various variants, have a shape which is approximately cylindrical (FIGS. 16A and 6B), approximately spherical (FIG. 16D), cylindrical on a part of their length (L) and spherical on the other part of their length (FIG. 16C), or have a decreasing cross section so as to give the eyelash(es), once moulded by the composition, a tapered appearance (FIG. 16B).

[0408] They may also have a semi-cylindrical shape in the case where the part (2a) of the mould is flat and the part (2b) of the mould is semi-cylindrical in the cavity (5) formation zone (FIG. 6A).

[0409] The depth (j) of the imprints 4 may range between 75 μm and 1.5 mm.

[0410] Each cavity (5) can receive one or more eyelashes (7), as illustrated respectively in FIGS. 17A and 17B.

[0411] Before moulding, the composition (6) may, according to various variants, be present on only one part of the cavity (5), as represented in FIGS. 18A to 18C, on all of the cavity, as illustrated in FIG. 18E, or absent from the cavity as represented in FIG. 18D. In the latter case, the composition may be injected via an injection channel (8) communicating with the cavities (5) of the mould, as illustrated in FIG. 19.

[0412] The composition (6) may be present initially, before putting the eyelashes in place, on the upper part of the cavity, corresponding to the part (2a) of the mould (FIG. 18A), on the lower part of the cavity, corresponding to the part (2b) of the mould (FIG. 18B), or both on the upper part and on the lower part of the cavity, corresponding to both parts (2a) and (2b) of the mould (FIGS. 18C and 18E).

[0413] The device (1) may comprise, or be placed in proximity to, a heating element (30), as illustrated very diagrammatically respectively in FIGS. 20A and 20B, in order to aggregate the particles in the dispersed state and/or to evaporate the liquid medium, the heating element (30) being, for example, a resistive element, a radiative element or a wave dispenser. The device may provide for the injection of the composition, in particular by an injection channel (8), as represented in FIG. 19.

[0414] The device (1) according to the invention may comprise a triggering system, such as a light element (32), as represented respectively in FIGS. 22A and 22B, for example an IR, UV or visible light illuminator. The mould (2) is then preferably transparent.

[0415] The device may comprise, or be placed in proximity to, a system (31) which assists drying by providing energy, in particular in the form of light or heat, and/or which comprises an aeration circuit, suction and/or blowing of air, as illustrated respectively in FIGS. 21A and 21B, in order to evaporate at least a part of the liquid medium.

[0416] The mould (2) may comprise an absorber specific for the liquid medium in order to eliminate at least a part of said liquid medium.

[0420] 2) Device

[0421] The device used in Example 1 is as described in FIGS. 1A and 1B.

[0422] It contains two mobile jaws (3a) and (3b), one of the two jaws having a temperature-controlled heating system.

[0423] The two parts (2a) and (2b) of the mould, placed between the two jaws, are made of cross-linked silicone elastomer and are 2 mm thick. They each comprise 20 grooves approximately 0.5 mm in diameter over a length of 2.5 cm.

[0424] The two jaws comprise two lugs and the two parts of the mould each comprise two housings which fit the lugs.

[0425] When the two parts of the mould are brought together, 20 leaktight cavities, closed at their end, are created on the sides.

[0426] 3) Cosmetic Assembly

[0427] The solidifiable cosmetic composition based on wax and latex is placed in the cavities and grooves of the two parts (2a) and (2b) of the mould.

[0428] The two jaws (3a) and (3b) containing the two parts (2a) and (2b) of the mould are moved near to the eyelash fringe and then closed so as to trap it.

[0429] The heating is activated by virtue of the heating element of the device (1) for 5 minutes until a temperature of approximately 70° C. is reached.

[0430] The heating is then stopped and the assembly is left to cool for 10 minutes. The two jaws (3a) and (3b) are then opened. The cosmetic composition has become solid by aggregation of the particles during the increase in temperature.

[0431] The two parts (2a) and (2b) of the mould remain attached to the eyelash fringe. The two parts of the mould are therefore moved apart, by pulling along their width, in order to release the eyelashes.

[0432] The result is then slightly rubbed in order to break the possible bridges of composition formed between two imprints.

[0433] A homogeneous makeup result is obtained on the eyelashes. The eyelashes are coated with a smooth, homogeneous and cohesive deposit.

TABLE-US-00002 % by weight (relative to the total weight of Compounds the composition) Latex Polyester-5 sold under the name Eastman 40 AQ 55 S Polymer by the company Eastman Chemicals Ethanol 20 Water qs 100

[0437] 2) Device

[0438] The device used is identical to that of Example 1.

[0439] 3) Cosmetic Assembly

[0440] The solidifiable cosmetic composition based on latex and ethanol is placed in the cavities and grooves of the two parts (2a) and (2b) of the mould.

[0441] The two jaws (3a) and (3b) containing the two parts (2a) and (2b) of the mould are moved near to the eyelash fringe and then closed so as to trap it.

[0442] The heating is activated by virtue of the heating element of the device (1) for 5 minutes until a temperature of approximately 70° C. is reached.

[0443] The heating is then stopped and the assembly is left to cool for 10 minutes. The two jaws (3a) and (3b) are then opened. The cosmetic composition has become solid by aggregation of the latex particles during the increase in temperature.

[0444] The two parts (2a) and (2b) of the mould remain attached to the eyelash fringe. The two parts of the mould are therefore moved apart, by pulling along their width, in order to release the eyelashes.

[0445] The result is then slightly rubbed in order to break the possible bridges of composition formed between two imprints.

[0446] A homogeneous makeup result is obtained on the eyelashes. The eyelashes are coated with a smooth, homogeneous and cohesive deposit.
