DETAILED DESCRIPTION

(35) The moulding device 1 represented in FIGS. 1 to 3 comprises a case 100 that can be manipulated by the user, with a frame 101 whose upper part 102 bears a first jaw with a first mould part 2a.

(36) The frame 100 has uprights 103 between which can move a second jaw with a second mould part 2b, borne by a slide rail 104.

(37) This slide rail may be moved between a bottom position, represented in FIG. 1, for insertion of the eyelashes between the jaws, and a top position, illustrated in FIG. 2, in which the two mould parts 2a, 2b are close or in contact to mould the composition on the eyelashes. The two jaws may be solicited in the open position by a spring, which is not shown.

(38) The lower jaw bearing the mould part 2b has, as may be seen in FIG. 3, an electrical resistance 110 running through it, which extends, for example, forming niches.

(39) The lower jaw may overhang relative to the case 100 over a distance s, as may the upper jaw.

(40) The electrical resistance 110 is, for example, 10 cm long.

(41) Each of the lower and upper jaws preferably comprises a metal plate, for example made of aluminium.

(42) The aluminium plate which bears the lower mould part 2b is, for example, 2 cm wide and 2 cm long. This plate is fixed by bonding with the electrical resistance on the slide rail 104.

(43) The course in the upward movement of the lower mould part 2b between the configurations of FIGS. 1 and 2 is, for example, between 1 and 3 cm and preferably about 2 cm.

(44) The intensity of the current passing through the electrical resistance 110 is chosen, for example, so as to obtain a temperature of 80° C. in the aluminium plate of the lower jaw in less than 20 seconds, from an initial temperature of 24° C. in an environment at 24° C.

(45) The case 100 may house an electronic circuit 600 for controlling the functioning of the device 1 represented schematically in FIG. 4.

(46) In the example considered, an electrical contactor 601 is actuated immediately on the upward movement of the lower jaw to allow the electronic circuit 600 to be informed thereof, and a temperature probe 602 is incorporated into the lower jaw so that its temperature can be known.

(47) The device 1 may incorporate a vibrator 605 controlled by the electronic circuit 600. This vibrator is, for example, incorporated into the case 100 close to the frame 103 or to one of the jaws. The vibration frequency is, for example, 100 Hz, and the vibration amplitude is 0.3 mm.

(48) The device 1 may comprise, where appropriate, one or more Peltier elements 610 to accelerate the cooling, incorporated into the jaws.

(49) The electronic circuit 600 comprises a controller arranged, as illustrated in FIG. 6, so as, in a first step 700, to maintain the temperature of the mould at a nominal preheating value T.sub.m, for example less than or equal to 15 degrees Celsius below the melting point of the cosmetic composition.

(50) This preheating may be applied only to the mould part in which the composition is received before closing the mould, especially when the composition is received only in the imprints of one of the mould parts, for example the lower part 2b as in the example of FIGS. 1 and 2. In this case, preheating is performed only on the lower mould part.

(51) When the user triggers the heating of the composition at a temperature T.sub.1 above T.sub.m, for example more than 5° C. above the melting point T.sub.m of the composition, in step 710, the electronic circuit 600 regulates the current in the heating resistance 110 so as to reach the temperature T.sub.1 and then maintain it in step 711.

(52) An indication that the temperature T.sub.1 has been reached may be given to the user, for example, by a sound and/or visual signal, for example the lighting of an indicator lamp on the case 100.

(53) The user positions his eyelashes between the mould parts 2a and 2b and, when he considers that the positioning is correct, he closes the mould at time t.sub.1 by moving the slide rail 104 to bring the mould part 2b close to the other part 2a.

(54) The bringing-together of the jaws is detected in step 712 by means of the contactor 601, which changes state. The electronic circuit 600 is arranged so as, in this case, to stop the heating in step 713 and, where appropriate, in the presence of one or more Peltier elements 610, to accelerate the cooling using these elements.

(55) FIG. 5 shows the change in temperature T between time t.sub.0 when the user triggers the heating of the composition to reach the value T.sub.1 and the time t.sub.1 when the bringing-together of the jaws of the mould parts commences.

(56) Immediately after stopping the heating at time t.sub.1, the vibrator 605 is switched on, when it is present in the device 1.

(57) Cooling of the composition is performed, the melting point is passed at time t.sub.2 and the temperature reaches a value T.sub.e at time t.sub.e with T.sub.e<T.sub.m.

(58) The user can then be informed that the composition is set by the emission of a sound and/or visual signal, for example the lighting of a corresponding indicator lamp on the case 100.

(59) When the temperature T.sub.e is reached, the switching-off of the vibrator 605 may be controlled by the circuit 600 in step 716 and the user can open the mould parts to remove the eyelashes.

(60) This process, which corresponds to the fourth aspect of the invention above, is performed with a hot-melt composition as described in chapter A above and with eyelash moulding cavities that may have any shape, and may especially originate from mould parts having rectilinear and parallel imprints 4 as illustrated in FIG. 7.

(61) However, this process is advantageously performed with mould parts made in accordance with the first, second or third aspect of the invention.

(62) FIG. 8 thus shows a mould part 2a or 2b for forming multiple points by moulding the composition on the eyelashes, for example using the device 1 represented in FIGS. 1 to 3.

(63) Each individual imprint 4 of the mould part has on the proximal side a single-strand section and which is divided into two at a branching 120 to form two branches 121 also known as tips.

(64) Thus, viewed from above, the mould part has imprints for receiving the eyelashes, which are each Y-shaped.

(65) The branching 120 is located, for example, along the individual cavity at a distance from the proximal end thereof that is between 1/3 and 2/3 of its length, the branching preferably being located as illustrated more than halfway along the length of the cavity.

(66) During the use of a mould comprising such a mould part, the eyelashes may be introduced into each individual cavity over a length less than the distance separating the branching 120 from the inlet of the cavity on the proximal side, so as to form a double tip for each eyelash introduced into an individual cavity.

(67) Multiple tips may also be made with X-shaped imprints 4, as illustrated in FIGS. 9 and 10.

(68) It is seen therein that each imprint comprises two branches 130 which cross at a branching 131 located, for example, between 1/3 and 2/3 of the length of the cavity measured along its longitudinal axis Xc.

(69) In the example considered, this branching 130 is at a distance l.sub.c from the proximal end 133 of the cavity that is less than half of its length, measured along the longitudinal axis of the cavity.

(70) The cross section of each branch 130 may decrease towards its distal end 137 as illustrated in FIG. 35.

(71) In the example considered, each branch 130 is rectilinear, but, in a variant not shown, may use non-rectilinear branches, which cross.

(72) During use, the eyelashes are each at least partially introduced into only one of the branches of an X-shaped unit, or, as a variant, two successive eyelashes are introduced into the two branches of the same unit.

(73) A mould may be made with cavities that cross at several points, so as to form a grid on the eyelashes, as illustrated in FIG. 11. In this figure, only the result of the moulding has been represented, without showing the eyelashes. Such a grid may contribute towards flattening the eyelash fringe and thus disciplining it, especially in the presence of shaggy eyelashes. The mould may comprise on each mould part an imprint that constitutes a half-grid. The eyelashes are sandwiched between the two half-grids closed on the two mould parts.

(74) It is seen in FIG. 11 that the mould may comprise cavities for making X-shaped units and other cavities for inverted V-shaped units or rectilinear branches that converge towards the exterior, without joining together.

(75) It is possible in accordance with the second aspect of the invention to make mould cavities whose shape and/or spacing or orientation changes along the mould, so as to allow the formation, on the eyelashes, of moulded units that vary along the eyelash fringe, as illustrated in FIG. 12. In this figure, the eyelashes themselves have not been shown, for the sake of clarity.

(76) There may thus be on a first zone Z1 a first type of unit formed on the eyelashes, and then along a zone Z2 a second type of unit, and finally along a zone Z3 a third type of unit, all the units being different.

(77) FIG. 13 illustrates evolutive makeup corresponding to a mould cavity length which tends to increase along the baseline from one end to the opposite end.

(78) The length may increase uniformly or non-uniformly.

(79) The angle α of the moulded unit relative to the normal to the eyelid may also change, for example increasing with the length of the cavities. The angle α passes, for example, from 0° to 30° as the length increases. The length of the moulded units passes, for example, from 3 mm to 15 mm.

(80) FIG. 14 represents a multizone evolutive makeup with lateral zones Z.sub.1 and Z.sub.3 containing rectilinear cavities, of different lengths, and a central zone Z.sub.2 containing Y-shaped units.

(81) FIG. 15 represents evolutive makeup in which the density of moulded units along the baseline varies, for example being substantially the same for the side zones Z.sub.1 and Z.sub.3 and higher for the central zone Z.sub.2.

(82) FIGS. 16 and 17 represent a variant of mould part 2a or 2b intended for forming a composition strip moulded on the eyelashes, in accordance with the third aspect of the invention.

(83) The mould part comprises, preferably close to its proximal edge 150 as illustrated, a groove 160, also known as a gutter, which is concave towards the proximal edge 150. This groove 160 is curvilinear and follows the curvilinear shape of the proximal edge 150 of the mould part.

(84) Such a groove 160 allows the formation by moulding on the eyelashes 7 of a composition strip 170 which has a curvilinear shape, as illustrated in FIG. 18 and which follows the contour of the eyelid P or of the adjacent eyebrow arch.

(85) The mould part may comprise only this curvilinear groove 160 so as to form only the composition strip on the eyelashes to connect them together and contribute towards disciplining them.

(86) Each mould part may comprise a single groove 160, the two grooves superposing when the two mould parts are placed in contact on the eyelashes, and a cavity for moulding a single composition strip.

(87) As a variant, only one of the mould parts, preferably the lower part 2b, comprises the groove 160, the other being free of such a groove.

(88) The groove 160 is preferably made a short distance d.sub.g from the proximal edge 150, preferably with d.sub.g≤2 mm, better still 1 mm.

(89) As illustrated in FIG. 19, the mould part 2a or 2b may comprise, besides the abovementioned groove 160, a plurality of individual imprints 4 for receiving the eyelashes, which not only allow the formation by moulding of the composition strip 170, but also the moulding of the composition on each eyelash, so as to coat them and/or to form multiple branches or extensions, as detailed previously, with the proviso of adapting the shape that is suitable.

(90) It is possible to make outside the eyelash fringe, with mould parts 2a, 2b as illustrated in FIG. 19, an article 200 comprising a preformed composition strip 210, bearing a plurality of fibres 220 as illustrated in FIG. 20.

(91) Such an article 200 may be applied after its manufacture onto an eyelash fringe by at least partially melting the composition strip using a heating applicator device, similar to an eyelash curler, for example. This makes it possible, on the one hand, to obtain a liner effect on the eyelid, by the proximity or contact of the composition strip 210 with the eyelid or the skin of the eyebrow arch, and, on the other hand, due to the presence of the fibres 220, to increase the eyelash density.

(92) It is seen that the lower mould part 2b can be incurved, where appropriate, as illustrated in FIG. 21, so as to reproduce the incurved shape of the eyelashes, the radius of curvature preferably being between 15 and 25 mm.

(93) The proximal edge of the mould part 2b intended to come into contact with the eyelid may have a radius of curvature of between 15 and 25 mm.

(94) The device 1 may be, according to one implementation variant of the invention, in the form of a clamp, as represented in FIGS. 22 and 23.

(95) Like the device represented in FIGS. 1 to 3, this device in the form of a clamp comprises a mould 2 in two parts 2a and 2b made of elastomer. The two parts 2a and 2b of the mould 2 each have, for example, a thickness e of about 2 mm. The two parts 2a and 2b of the mould 2 comprise imprints 4 suitable for performing the invention according to its first or its second aspect, for example. The device 1 comprises two jaws 3a and 3b which carry respectively the mould parts 2a and 2b. The functioning may take place in the same manner as described in reference to FIG. 6 so as to perform the invention according to its fourth aspect.

(96) Each part 2a, 2b comprises, for example, about fifteen imprints 4, for example having a width l of about 0.5 mm, a length L of about 2.5 cm, and a decreasing semicircular cross section over at least part of their length, 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 each other at least on the proximal side of the mould. The imprints may be evenly spaced out, according to a step p of 1.5 mm, centre to centre.

(97) The mould 2a, 2b may have a radius of curvature in the direction M of FIG. 23 of between 15 and 25 mm so as to follow the shape of the eyelashes. The edge of part 2b intended to come into contact with the eyelid may have a rounded shape, concave towards the exterior, with a radius of curvature preferably between 15 and 25 mm.

(98) 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.

(99) When the jaws are closed against each other, as represented in FIG. 22, cavities 5 are formed by means of the imprints 4, which are superimposed in pairs. About fifteen cavities 5 are thus created, for example. The cavities 5 are closed on the sides and open out to the exterior, on the proximal front side where the eyelashes are introduced, via a circular opening through which the eyelashes are introduced. The cavities may be closed at their rear distal end.

(100) 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.

(101) The cosmetic composition 6 to be moulded is placed in imprints 4 of part 2b of the mould 2 before introduction of the eyelashes. The composition 6 is preferably a cosmetic composition having a melting point of between 40° C. and 120° C., and comprising at least 15% by weight of meltable compound(s), relative to the total weight of the composition, as previously described.

(102) Only one of the mould 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 performed very accurately.

(103) By way of example, FIG. 24 represents a device 1 in which part 2a of the mould 2 is smooth and part 2b comprises semicircular imprints 4.

(104) 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.

(105) 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 each other. The device 1 in the form of a clamp may thus comprise, for example, a male and female cone guidance system.

(106) 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. 25A and 25B, such that the jaws can be moved together by a pivoting movement relative to each other. Each cavity formed by the superposition 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.

(107) During the use of the device 1, the angle α made by the moulding plane with the horizontal may be zero or non-zero, in particular between 20 and 40°, as illustrated in FIG. 26. Inclining the plane of the moulds makes it possible to push the curvature of the edge coming into contact with the eyelid as close as possible to the curvature of the eyelid itself.

(108) The hinge 40 may comprise one or more springs 50 as represented in FIG. 27, which assist the opening movement for example.

(109) The device 1 in the form of a clamp may comprise a single housing 20a for receiving a finger, as illustrated in FIG. 28, or two housings, as previously described.

(110) 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. 26.

(111) Each mould part 2a, 2b may be integrated into the corresponding jaw 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.

(112) 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, so as to improve the holding of the clamps in place and the overall shape of the mould, while facilitating demoulding.

(113) It is possible for the mould 2a, 2b to not be integrated into the jaws 3a, 3b. The jaws then bear the mould parts, which are brought close 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.

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

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

(116) 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 obstruction allowing optimal vision for the user, and of being easy to use.

(117) 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. 29A and 29B. In the case where it is sought to make a composition strip connecting several eyelashes together in accordance with the third aspect of the invention, care will obviously be taken to ensure that such blades do not section the strip.

(118) The mould 2 may also comprise, as illustrated in FIG. 30, reliefs 9 between two imprints 4 intended to form two cavities, so as to cut any bridges of composition.

(119) The device 1 may comprise blades 11 which serve to cut any bridges of composition between two cavities, as illustrated in FIG. 31.

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

(121) As a variant, the material of 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 part 2a is made.

(122) Yet other systems may be used for cutting the bridges, for example a system for sending compressed air via slits located between the imprints or a heating element.

(123) 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. 32 and 33. 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 the 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.

(124) The additional fibres may in particular be false eyelashes.

(125) The additional fibres 12 may be placed on hold in the imprints 4 of the mould 2, as illustrated in FIG. 34A. 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 as illustrated in FIG. 34B. The imprints 4 have been represented here as rectilinear, but, as a variant, they may comprise branchings in accordance with the first aspect of the invention, or may be directed towards producing evolutive makeup in accordance with the second aspect of the invention.

(126) The cavities may have, over at least part of their length, a semi-cylindrical shape in the case where part 2a of the mould is flat and part 2b of the mould is semi-cylindrical in the cavity 5 formation zone, as illustrated in FIG. 24.

(127) Each cavity 5 can receive one or more eyelashes 7, as illustrated, respectively, in FIGS. 35 and 36.

(128) Before moulding, the composition 6 may, according to various variants, be present on only one part of the cavity 5, as represented in FIGS. 37A to 37C, on all of the cavity, as illustrated in FIG. 37E, or absent from the cavity as represented in FIG. 37D. 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. 38.

(129) The composition 6 may be present initially, before putting the eyelashes in place, on the upper part of the cavity, corresponding to mould part 2a, as illustrated in FIG. 37A, on the lower part of the cavity, corresponding to mould part 2b, as illustrated in FIG. 37B, or both on the upper part and on the lower part of the cavity, corresponding to both parts 2a and 2b of the mould, as illustrated in FIGS. 37C and 37E.

(130) Except when it is desired to perform the fourth aspect of the invention, the hot-melt composition may be replaced with a cosmetic composition that is fluid at room temperature and that contains at least particles in the dispersed state in a liquid medium.

(131) The device may then comprise or may be placed in proximity to a heating element, the heating element being, for example, a resistive element, a radiative element or a wave dispenser.

(132) The device may comprise or may be placed in proximity to a system 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, in order to evaporate at least part of the liquid medium.

(133) The mould may comprise an absorber specific for the liquid medium in order to eliminate at least part of the liquid medium.

(134) In another example of implementation of the invention, a composition which is a composition that is fluid at room temperature and contains at least one compound that is activatable via a physical or chemical stimulus is used. The eyelashes and the composition are enclosed in the mould. After reaction, demoulding is performed.

(135) The device may then comprise or be placed in proximity to a heating element so as to accelerate the reaction, the heating element being, for example, a resistive element, a radiative element or a wave dispenser.

(136) The device according to the invention may comprise a triggering system, such as a light element, in order to trigger the reaction, for example an IR, UV or visible light illuminator. The mould is then preferably transparent to the wavelengths used to trigger the reaction.

(137) In another example of implementation of the invention, the composition is a ductile composition and preferably has a Young's modulus of less than or equal to 100 MPa at room temperature and ambient pressure.

(138) FIGS. 39A to 39C illustrate various steps of an example of compression moulding. Composition 6 is initially present in part 2a of the mould and the eyelashes 7 in the other part 2b.

(139) After closure of the two parts of the mould, the cavities 5 are formed, as illustrated in FIGS. 39B and 39C.

(140) A compression exerted on the mould, which is flexible, makes it possible to reduce the volume of the cavities of the mould, as illustrated in FIG. 39C, and to enhance the contact between the eyelashes 7 and the composition 6.

(141) FIGS. 40A and 40B represent a mould before and after compression of the cavities, without the eyelashes or the composition. The largest dimension of the cavities A is, for example, 3 mm before compression and it is reduced by at least 30%, for example to 2 mm, after compression.

Example 16

(316) A mould is made from a silicone material, with, on one of the mould parts, a curvilinear groove about 3 cm long, 2 mm wide and 1 mm high, as illustrated in FIG. 16. It is filled with a hot-melt composition. After cooling, the article made is released.

(317) This article is then placed on a heated eyelash curling machine, for example a Talika brand machine.

(318) The eyelash curler is used as a heated applicator, taking care not to curl the eyelashes.
