Definitions
- the present invention relates to the makeup of eyelashes.
- the invention aims more particularly but not exclusively to provide a physical elongation eyelashes.
- US 2,630,516 discloses an eyelash curling iron provided externally with a sheath of a fibrous material, preferably a chamois leather, for retaining an excess of mascara.
- heat is used to freeze mascara.
- EP 1 468 627 A1 discloses a heating applicator for applying a viscous composition having a particular thermal profile.
- the composition is deposited on the applicator by immersing it in a bottle containing the composition, provided with a wringing member.
- the devices disclosed in these publications are relatively complex and relate more to the bending of the eyelashes than their elongation.
- a mascara composition comprising fibers.
- the latter can, when they are sufficiently rigid and visible and they are at the end of eyelashes, provide an elongation of the eyelash.
- the elongation gain obtained by such a composition remains moderate because it is relatively difficult to orient the fibers at the end of the eyelashes.
- Another solution may consist, as disclosed in WO 2006/037904 A1 to use a mascara composition having a non-zero magnetic susceptibility and to create in the vicinity of the eyelash a magnetic field to act on the composition present on the eyelash to lengthen it by a magnetic attraction effect.
- compositions of mascara having a character running at room temperature as disclosed in the application EP 1 430 868 A1 .
- Such a composition may, however, prove to be relatively difficult to apply because the control of the length of the yarns formed at the end of the eyelashes proves to be delicate.
- the Applicant has developed mascara compositions having a character spinning only hot.
- the invention aims to facilitate the application of such compositions and more generally the application of any composition having a property to the application which is modified by application of heat.
- composition is for example intended to lengthen the eyelashes but can still be used to make up otherwise, including bending, according to its formulation.
- the above property is for example the spinning character, the composition having in this case a spinning character when heated above a certain temperature, for example 40 Ā° C.
- the composition may have a viscosity that decreases with temperature.
- the invention can facilitate the handling of the composition since it is sufficient in one case to arrange the applicator tip on the heating support before applying to the eyelashes, and when the applicator tip has ceased to be usable. , it can be easily replaced by a new applicator tip.
- the fitting can be carried out with insertion of the heating support into a cavity of the applicator tip.
- the fitting can be carried out with insertion of the applicator tip into a cavity of the heating support.
- the fitting can be carried out axially, along the longitudinal axis of the heating support. Alternatively, the fitting can be performed laterally in a direction transverse to the longitudinal axis of the heating support. The fitting can still be performed more complex, for example with a rotation or with a snap.
- the term "fitting" must therefore be understood in a broad sense.
- a hollow form of applicator tip may be preferred in certain exemplary embodiments of the invention, because it allows it to cover easily, if desired, the heating support over its entire circumference, which facilitates the use of the application device in multiple orientations relative to the eyelashes.
- the applicator tip may also be in the form of a nail, the body of which serves for fixing it on the heating support and the head for application to the eyelashes.
- the applicator tip may still not cover the heating support over its entire circumference, which is the case for example when it has a tile or dome shape.
- the heating support may have a heating surface extending 360 Ā° about the longitudinal axis of the heating support.
- the heating support may have a heating surface that extends only over a limited angular sector around the longitudinal axis of the heating support.
- the heating surface can extend angularly about 180 Ā°.
- the heating support may have an enlargement on either side of the heating surface, in order to delay and / or oppose the flow of the composition once the tip has been heated.
- the heating support may comprise opposite the hot surface of the teeth, sometimes also called pins, for example from molding with the heating support.
- the applicator tip may be formed exclusively by the composition to be applied, especially when it is solid at room temperature (25 Ā° C.).
- the composition may be molded directly with the shape of the applicator tip for subsequent use by the consumer on the application device.
- the applicator tip is composite, and the composition is for example in the form of a coating exterior to the surface of a substrate shaped to mount on the heating support.
- Such a composite structure may be desirable for example for compositions not having the rheology suitable for molding an applicator tip or for improving the retention of the composition on the hot applicator tip.
- the heating support has a finger shape.
- the applicator tip may then for example have a shape of a glove finger, being for example configured to cover the heating support over at least a portion of its length from its distal end.
- a form of applicator tip glove finger can allow to use the distal end of the applicator tip to apply the composition on the eyelashes, which may allow easier localized treatment, for example cil per eyelash.
- the applicator tip may, in at least one cross section, be continuous over its entire circumference.
- the applicator tip has, in at least one cross-section, an aperture, this aperture being, for example, a slot extending longitudinally on the applicator tip over at least a portion of its length.
- the applicator tip may have no aperture on its side surface.
- the heating support may comprise an envelope having a housing in which is arranged at least one heating resistor, this housing opening for example at one end of the envelope so as to allow the insertion of the heating resistor into the envelope after manufacture of the envelope.
- This housing may be central, so as to allow, if desired, obtaining a homogeneous temperature around the longitudinal axis of the heating support.
- the heating support comprises an envelope which is overmolded on the heating resistor.
- the envelope may be made of a good heat-conducting material, for example a metal or a thermoplastic or cross-linkable material loaded with metal particles or having a good thermal conductivity.
- the outer surface of the heating support can be defined at least partially or completely by a metal, a glass, a ceramic or an elastomer.
- the application device may comprise at least one switch to allow the user to trigger the heating of the heating support.
- This switch is for example a contactor, for example a push-button, triggering the heating of the heating support when depressed by the user, heating the heating support stopping for example as soon as the contactor is released by the user. This can allow the user to create relatively short heating pulses and well controlled over time, which can facilitate the operation of application of the composition on the eyelashes.
- the application device comprises a switch that can take a position in which, even when released by the user, the heating support remains energized, if necessary for a predefined period of time. way to save the power source.
- the application device may comprise a temperature regulating member of the heating support.
- the application device may also include a light indicator informing the user for example on the supplied or unpowered state of the heating support and / or on the temperature thereof.
- the indicator light is, for example, a light that comes on when the heating support is electrically powered and changes color, flashes or stops flashing when the appropriate temperature for the application is reached.
- the application device may also include a thermochromic indicator, for example changing color when a temperature suitable for use is reached.
- the application device may comprise a housing for receiving at least one spare applicator tip, before mounting on the heating support.
- the application device may comprise a housing housing an electrical source, for example at least one battery or accumulator.
- the application device can still be powered by the mains, for example by means of a step-down transformer.
- the use of a 9V battery to power the heating media can increase the current in the resistor and allow a faster rise in temperature, which can facilitate makeup.
- the electrical source and the heating support are, for example, chosen so that the heating support can reach a surface temperature of, for example, less than or equal to 95 Ā° C., for example 45 and 95 Ā° C., for example between 45 Ā° C. and 90 Ā° C, better still at least 60 Ā° C in less than 120 s, better 30 s, starting from an initial temperature of 25 Ā° C in a closed environment at 25 Ā° C.
- the heating support may have a shape facilitating its cleaning and / or removal of the applicator tip once it is used, including a generally conical shape, converging towards the distal end of the heating support. Such a shape may also be preferred when the heating support is loaded by being immersed in the composition.
- the heating support may be made of a material having a state and / or a surface tension such that the composition is non-adherent at 25 Ā° C to the heating support.
- the surface of the heating support may be smooth and nonporous or have teeth, ridges and / or grooves.
- the heating support may be made of PTFE (TeflonĀ®) or have a coating of PTFE or similar material.
- the heating support is fixed relative to a gripping portion of the application device.
- the heating support is movable relative to a gripping portion of the application device.
- the heating support is for example mobile in translation. This can reduce the size of the application device in the absence of use.
- the application device may also be arranged such that the displacement of the heating support relative to the gripping portion causes ejection of the applicator tip of the heating support.
- the applicator tip may for example comprise at its base an extra thickness, for example in the form of a flange, coming to bear against a wall of the application device when the heating support is moved.
- the heating support may also be mobile in rotation, for example around an axis of rotation perpendicular to its longitudinal axis, on itself or around any axis not coincident with its longitudinal axis.
- the application device may also comprise, in an alternative embodiment of the invention, an ejection member movable relative to the heating support.
- This ejection member is for example in the form of a pusher which is moved by the user to drive the applicator tip out of the heating support.
- the heating support may have any form suitable for the desired makeup.
- the heating support may have a longitudinal axis which is rectilinear or not.
- a curvilinear longitudinal axis can for example further improve the ergonomics.
- the longitudinal axis of the heating support may be coincident or parallel to the longitudinal axis of a gripping portion of the application device, this gripping portion being for example merged with a housing of the application device.
- the longitudinal axis of the support may be rectilinear and make an angle with the longitudinal axis of the gripping portion of the application device.
- the heating support may have a cross section which decreases towards its distal end. This can facilitate the removal of the applicator tip.
- the support may comprise a heating resistor disposed inside an envelope which may have a substantially constant thickness, for example to more easily obtain a relatively homogeneous temperature over the entire length of the heating support.
- the casing may have a longitudinally varying wall thickness depending on a desired temperature profile.
- the thickness of the envelope may, for example, decrease towards the distal end of the heating support, for example to obtain a higher temperature. high end of the heating support.

Description
La prƩsente invention concerne le maquillage des cils.The present invention relates to the makeup of eyelashes.
L'invention vise plus particuliĆØrement mais non exclusivement Ć procurer un allongement physique des cils.The invention aims more particularly but not exclusively to provide a physical elongation eyelashes.
Il est connu par les publications
Les dispositifs divulguƩs dans ces publications sont relativement complexes et concernent davantage le recourbement des cils que leur allongement.The devices disclosed in these publications are relatively complex and relate more to the bending of the eyelashes than their elongation.
Il est connu, pour obtenir un effet d'allongement des cils, d'utiliser une composition de mascara comportant des fibres. Ces derniĆØres peuvent, lorsqu'elles sont suffisamment rigides et visibles et qu'elles se trouvent en bout de cils, procurer un allongement du cil. Le gain en allongement obtenu par une telle composition reste modĆ©rĆ© car il est relativement difficile d'orienter les fibres en bout de cils.It is known to obtain an effect of elongation of the eyelashes, to use a mascara composition comprising fibers. The latter can, when they are sufficiently rigid and visible and they are at the end of eyelashes, provide an elongation of the eyelash. The elongation gain obtained by such a composition remains moderate because it is relatively difficult to orient the fibers at the end of the eyelashes.
Une autre solution peut consister, comme divulguƩ dans
Une autre possibilitĆ© consiste Ć utiliser une composition de mascara prĆ©sentant un caractĆØre filant Ć tempĆ©rature ambiante, comme divulguĆ© dans la demande
La demanderesse a mis au point des compositions de mascara prĆ©sentant un caractĆØre filant seulement Ć chaud.The Applicant has developed mascara compositions having a character spinning only hot.
L'invention vise Ć faciliter l'application de telles compositions et plus gĆ©nĆ©ralement l'application de toute composition ayant une propriĆ©tĆ© Ć l'application qui est modifiĆ©e par application de chaleur.The invention aims to facilitate the application of such compositions and more generally the application of any composition having a property to the application which is modified by application of heat.
L'invention concerne ainsi, selon l'un de ses aspects, un ensemble comportant :
- un dispositif d'application comportant un support chauffant,
- un embout applicateur ayant une forme adaptĆ©e Ć son montage par emmanchement sur le support chauffant,
- une composition Ć appliquer sur les cils, prĆ©sentant au moins une propriĆ©tĆ© qui varie en fonction de la tempĆ©rature, ladite composition Ć©tant contenue dans l'embout applicateur, l'embout applicateur Ć©tant rĆ©alisĆ© au moins partiellement, voire entiĆØrement, avec la composition.
- an application device comprising a heating support,
- an applicator tip having a shape adapted to its mounting by fitting on the heating support,
- a composition to be applied to the eyelashes, exhibiting at least one property that varies as a function of temperature, said composition being contained in the applicator tip, the applicator tip being made at least partially, or entirely, with the composition.
La composition est par exemple destinĆ©e Ć allonger les cils mais peut encore servir Ć les maquiller autrement, notamment les recourber, selon sa formulation.The composition is for example intended to lengthen the eyelashes but can still be used to make up otherwise, including bending, according to its formulation.
La propriĆ©tĆ© ci-dessus est par exemple le caractĆØre filant, la composition prĆ©sentant dans ce cas un caractĆØre filant lorsqu'elle est chauffĆ©e au-delĆ d'une certaine tempĆ©rature, par exemple 40 Ā°C.The above property is for example the spinning character, the composition having in this case a spinning character when heated above a certain temperature, for example 40 Ā° C.
La composition peut prƩsenter une viscositƩ qui diminue avec la tempƩrature.The composition may have a viscosity that decreases with temperature.
L'invention peut faciliter la manipulation de la composition puisqu'il suffit dans un cas de disposer l'embout applicateur sur le support chauffant avant de procĆ©der Ć l'application sur les cils, et lorsque l'embout applicateur a cessĆ© d'ĆŖtre utilisable, celui-ci peut ĆŖtre remplacĆ© aisĆ©ment par un nouvel embout applicateur.The invention can facilitate the handling of the composition since it is sufficient in one case to arrange the applicator tip on the heating support before applying to the eyelashes, and when the applicator tip has ceased to be usable. , it can be easily replaced by a new applicator tip.
L'utilisation d'un embout applicateur ayant une forme adaptĆ©e Ć l'emmanchement simplifie considĆ©rablement la mise en place de la composition sur le support chauffant comparativement par exemple aux dispositifs divulguĆ©s dans les publications
L'emmanchement peut s'effectuer avec insertion du support chauffant dans une cavitƩ de l'embout applicateur.The fitting can be carried out with insertion of the heating support into a cavity of the applicator tip.
En variante, l'emmanchement peut s'effectuer avec insertion de l'embout applicateur dans une cavitƩ du support chauffant.Alternatively, the fitting can be carried out with insertion of the applicator tip into a cavity of the heating support.
L'emmanchement peut s'effectuer axialement, selon l'axe longitudinal du support chauffant. En variante, l'emmanchement peut s'effectuer latĆ©ralement, dans une direction transversale Ć l'axe longitudinal du support chauffant. L'emmanchement peut encore s'effectuer de maniĆØre plus complexe, par exemple avec une rotation ou avec un encliquetage. Le terme Ā« emmanchement Ā» doit donc ĆŖtre compris avec un sens large.The fitting can be carried out axially, along the longitudinal axis of the heating support. Alternatively, the fitting can be performed laterally in a direction transverse to the longitudinal axis of the heating support. The fitting can still be performed more complex, for example with a rotation or with a snap. The term "fitting" must therefore be understood in a broad sense.
Une forme creuse d'embout applicateur peut ĆŖtre prĆ©fĆ©rĆ©e dans certains exemples de mise en oeuvre de l'invention, car elle permet Ć celui-ci de recouvrir facilement, si on le souhaite, le support chauffant sur toute sa circonfĆ©rence, ce qui facilite l'utilisation du dispositif d'application dans de multiples orientations relativement aux cils.A hollow form of applicator tip may be preferred in certain exemplary embodiments of the invention, because it allows it to cover easily, if desired, the heating support over its entire circumference, which facilitates the use of the application device in multiple orientations relative to the eyelashes.
L'embout applicateur peut encore avoir une forme de clou, dont le corps sert Ć sa fixation sur le support chauffant et la tĆŖte Ć l'application sur les cils.The applicator tip may also be in the form of a nail, the body of which serves for fixing it on the heating support and the head for application to the eyelashes.
L'embout applicateur peut encore ne pas recouvrir le support chauffant sur toute sa circonfƩrence, ce qui est le cas par exemple lorsqu'il prƩsente une forme de tuile ou de dƓme.The applicator tip may still not cover the heating support over its entire circumference, which is the case for example when it has a tile or dome shape.
Le support chauffant peut avoir une surface chauffante qui s'Ć©tend sur 360Ā° autour de l'axe longitudinal du support chauffant. En variante, le support chauffant peut avoir une surface chauffante qui ne s'Ć©tend que sur un secteur angulaire limitĆ© autour de l'axe longitudinal du support chauffant.The heating support may have a heating surface extending 360 Ā° about the longitudinal axis of the heating support. Alternatively, the heating support may have a heating surface that extends only over a limited angular sector around the longitudinal axis of the heating support.
Lorsque l'embout applicateur a une forme de tuile, la surface chauffante peut s'Ć©tendre angulairement sur 180Ā° environ. Le support chauffant peut prĆ©senter un Ć©largissement de part et d'autre de la surface chauffante, afin de retarder et/ou s'opposer Ć l'Ć©coulement de la composition une fois l'embout rĆ©chauffĆ©.When the applicator tip has a tile shape, the heating surface can extend angularly about 180 Ā°. The heating support may have an enlargement on either side of the heating surface, in order to delay and / or oppose the flow of the composition once the tip has been heated.
Notamment lorsque l'embout applicateur ne s'Ć©tend pas tout autour du support chauffant, par exemple prĆ©sente une forme de tuile, le support chauffant peut comporter Ć l'opposĆ© de la surface chaude des dents, parfois encore appelĆ©es picots, par exemple venues de moulage avec le support chauffant.In particular, when the applicator tip does not extend all around the heating support, for example has a tile shape, the heating support may comprise opposite the hot surface of the teeth, sometimes also called pins, for example from molding with the heating support.
L'embout applicateur peut ĆŖtre formĆ© exclusivement par la composition Ć appliquer, notamment lorsque celle-ci est solide Ć tempĆ©rature ambiante (25 Ā°C). Dans ce cas, la composition peut ĆŖtre moulĆ©e directement avec la forme de l'embout applicateur en vue de son utilisation ultĆ©rieure par le consommateur sur le dispositif d'application.The applicator tip may be formed exclusively by the composition to be applied, especially when it is solid at room temperature (25 Ā° C.). In this case, the composition may be molded directly with the shape of the applicator tip for subsequent use by the consumer on the application device.
Dans une variante de mise en oeuvre de l'invention, l'embout applicateur est composite, et la composition se prĆ©sente par exemple sous la forme d'un revĆŖtement extĆ©rieur Ć la surface d'un substrat conformĆ© pour se monter sur le support chauffant. Une telle structure composite peut s'avĆ©rer souhaitable par exemple pour des compositions ne prĆ©sentant pas la rhĆ©ologie adaptĆ©e au moulage d'un embout applicateur ou pour amĆ©liorer la rĆ©tention de la composition sur l'embout applicateur Ć chaud.In an alternative embodiment of the invention, the applicator tip is composite, and the composition is for example in the form of a coating exterior to the surface of a substrate shaped to mount on the heating support. Such a composite structure may be desirable for example for compositions not having the rheology suitable for molding an applicator tip or for improving the retention of the composition on the hot applicator tip.
Selon la forme donnĆ©e Ć l'embout applicateur, diffĆ©rents effets de maquillage peuvent ĆŖtre obtenus.Depending on the shape given to the applicator tip, different makeup effects can be obtained.
Dans des exemples de mise en oeuvre de l'invention, le support chauffant prĆ©sente une forme de doigt. L'embout applicateur peut alors prĆ©senter par exemple une forme en doigt de gant, Ć©tant par exemple configurĆ© pour venir recouvrir le support chauffant sur au moins une partie de sa longueur Ć compter de son extrĆ©mitĆ© distale.In exemplary embodiments of the invention, the heating support has a finger shape. The applicator tip may then for example have a shape of a glove finger, being for example configured to cover the heating support over at least a portion of its length from its distal end.
Une forme d'embout applicateur en doigt de gant peut permettre d'utiliser l'extrƩmitƩ distale de l'embout applicateur pour appliquer la composition sur les cils, ce qui peut permettre plus facilement un traitement localisƩ, par exemple cil par cil.A form of applicator tip glove finger can allow to use the distal end of the applicator tip to apply the composition on the eyelashes, which may allow easier localized treatment, for example cil per eyelash.
L'embout applicateur peut, dans au moins une section transversale, ĆŖtre continu sur toute sa circonfĆ©rence. En variante, l'embout applicateur prĆ©sente dans au moins une section transversale un ajour, cet ajour Ć©tant par exemple une fente s'Ć©tendant longitudinalement sur l'embout applicateur, sur au moins une portion de sa longueur.The applicator tip may, in at least one cross section, be continuous over its entire circumference. In a variant, the applicator tip has, in at least one cross-section, an aperture, this aperture being, for example, a slot extending longitudinally on the applicator tip over at least a portion of its length.
L'embout applicateur peut ne prƩsenter aucun ajour sur sa surface latƩrale.The applicator tip may have no aperture on its side surface.
Le support chauffant peut comporter une enveloppe prĆ©sentant un logement dans lequel est disposĆ©e au moins une rĆ©sistance chauffante, ce logement dĆ©bouchant par exemple Ć une extrĆ©mitĆ© de l'enveloppe de faƧon Ć permettre l'insertion de la rĆ©sistance chauffante dans l'enveloppe aprĆØs la fabrication de l'enveloppe. Ce logement peut ĆŖtre central, de faƧon Ć permettre, si cela est souhaitĆ©, l'obtention d'une tempĆ©rature homogĆØne autour de l'axe longitudinal du support chauffant.The heating support may comprise an envelope having a housing in which is arranged at least one heating resistor, this housing opening for example at one end of the envelope so as to allow the insertion of the heating resistor into the envelope after manufacture of the envelope. This housing may be central, so as to allow, if desired, obtaining a homogeneous temperature around the longitudinal axis of the heating support.
En variante, le support chauffant comporte une enveloppe qui est surmoulƩe sur la rƩsistance chauffante.Alternatively, the heating support comprises an envelope which is overmolded on the heating resistor.
L'enveloppe peut ĆŖtre rĆ©alisĆ©e dans un matĆ©riau bon conducteur de la chaleur, par exemple un mĆ©tal ou une matiĆØre thermoplastique ou rĆ©ticulable chargĆ©e de particules mĆ©talliques ou ayant une bonne conductivitĆ© thermique.The envelope may be made of a good heat-conducting material, for example a metal or a thermoplastic or cross-linkable material loaded with metal particles or having a good thermal conductivity.
La surface extĆ©rieure du support chauffant peut ĆŖtre dĆ©finie au moins partiellement, voire complĆØtement, par un mĆ©tal, un verre, une cĆ©ramique ou un Ć©lastomĆØre.The outer surface of the heating support can be defined at least partially or completely by a metal, a glass, a ceramic or an elastomer.
Le dispositif d'application peut comporter au moins un interrupteur pour permettre Ć l'utilisateur de dĆ©clencher le chauffage du support chauffant. Cet interrupteur est par exemple un contacteur, par exemple un bouton-poussoir, dĆ©clenchant le chauffage du support chauffant lorsqu'enfoncĆ© par l'utilisateur, le chauffage du support chauffant s'arrĆŖtant par exemple dĆØs que le contacteur est relĆ¢chĆ© par l'utilisateur. Cela peut permettre Ć l'utilisateur de crĆ©er des impulsions de chauffage relativement courtes et bien maĆ®trisĆ©es dans le temps, ce qui peut faciliter l'opĆ©ration d'application de la composition sur les cils.The application device may comprise at least one switch to allow the user to trigger the heating of the heating support. This switch is for example a contactor, for example a push-button, triggering the heating of the heating support when depressed by the user, heating the heating support stopping for example as soon as the contactor is released by the user. This can allow the user to create relatively short heating pulses and well controlled over time, which can facilitate the operation of application of the composition on the eyelashes.
Dans une variante de mise en oeuvre de l'invention, le dispositif d'application comporte un interrupteur pouvant prendre une position dans laquelle, mĆŖme une fois relĆ¢chĆ© par l'utilisateur, le support chauffant reste alimentĆ©, le cas Ć©chĆ©ant pendant une durĆ©e prĆ©dĆ©finie de faƧon Ć Ć©conomiser la source Ć©lectrique.In an alternative embodiment of the invention, the application device comprises a switch that can take a position in which, even when released by the user, the heating support remains energized, if necessary for a predefined period of time. way to save the power source.
Le dispositif d'application peut comporter un organe de rƩgulation de la tempƩrature du support chauffant.The application device may comprise a temperature regulating member of the heating support.
Le dispositif d'application peut Ʃgalement comporter un indicateur lumineux renseignant l'utilisateur par exemple sur l'Ʃtat alimentƩ ou non du support chauffant et/ou sur la tempƩrature de celui-ci.The application device may also include a light indicator informing the user for example on the supplied or unpowered state of the heating support and / or on the temperature thereof.
L'indicateur lumineux est par exemple un voyant qui s'allume lorsque le support chauffant est alimentĆ© Ć©lectriquement et qui change de couleur, clignote ou cesse de clignoter lorsque la tempĆ©rature convenant Ć l'application est atteinte.The indicator light is, for example, a light that comes on when the heating support is electrically powered and changes color, flashes or stops flashing when the appropriate temperature for the application is reached.
Le dispositif d'application peut Ć©galement comporter un indicateur thermochromique, par exemple changeant de couleur lorsqu'une tempĆ©rature convenant Ć l'utilisation est atteinte.The application device may also include a thermochromic indicator, for example changing color when a temperature suitable for use is reached.
Le dispositif d'application peut comporter un logement permettant de recevoir au moins un embout applicateur de rƩserve, avant montage sur le support chauffant.The application device may comprise a housing for receiving at least one spare applicator tip, before mounting on the heating support.
Le dispositif d'application peut comporter un boĆ®tier logeant une source Ć©lectrique, par exemple au moins une pile ou un accumulateur. Le dispositif d'application peut encore ĆŖtre alimentĆ© par le secteur, par exemple par l'intermĆ©diaire d'un transformateur abaisseur de tension. L'utilisation, pour alimenter le support chauffant, d'une pile de 9V peut accroĆ®tre l'intensitĆ© du courant dans la rĆ©sistance et permettre une montĆ©e en tempĆ©rature plus rapide, ce qui peut faciliter le maquillage.The application device may comprise a housing housing an electrical source, for example at least one battery or accumulator. The application device can still be powered by the mains, for example by means of a step-down transformer. The use of a 9V battery to power the heating media can increase the current in the resistor and allow a faster rise in temperature, which can facilitate makeup.
La source Ć©lectrique et le support chauffant sont par exemple choisis de telle sorte que le support chauffant puisse atteindre une tempĆ©rature de surface par exemple infĆ©rieure ou Ć©gale Ć 95 Ā°C, par exemple 45 et 95 Ā°C, par exemple comprise entre 45 Ā°C et 90 Ā°C, mieux d'au moins 60 Ā°C en moins de 120 s, mieux 30 s, en partant d'une tempĆ©rature initiale de 25 Ā°C dans un environnement clos Ć 25 Ā°C.The electrical source and the heating support are, for example, chosen so that the heating support can reach a surface temperature of, for example, less than or equal to 95 Ā° C., for example 45 and 95 Ā° C., for example between 45 Ā° C. and 90 Ā° C, better still at least 60 Ā° C in less than 120 s, better 30 s, starting from an initial temperature of 25 Ā° C in a closed environment at 25 Ā° C.
Le support chauffant peut prĆ©senter une forme facilitant son nettoyage et/ou l'enlĆØvement de l'embout applicateur une fois celui-ci utilisĆ©, notamment une forme gĆ©nĆ©ralement conique, convergeant en direction de l'extrĆ©mitĆ© distale du support chauffant. Une telle forme peut Ć©galement ĆŖtre prĆ©fĆ©rĆ©e lorsque le support chauffant est chargĆ© en Ć©tant plongĆ© dans la composition. Le support chauffant peut ĆŖtre rĆ©alisĆ© dans un matĆ©riau ayant un Ć©tat et/ou une tension de surface telle que la composition soit non adhĆ©rente Ć 25 Ā°C au support chauffant. La surface du support chauffant peut ĆŖtre lisse et non poreuse ou comporter des dents, stries et/ou rainures.The heating support may have a shape facilitating its cleaning and / or removal of the applicator tip once it is used, including a generally conical shape, converging towards the distal end of the heating support. Such a shape may also be preferred when the heating support is loaded by being immersed in the composition. The heating support may be made of a material having a state and / or a surface tension such that the composition is non-adherent at 25 Ā° C to the heating support. The surface of the heating support may be smooth and nonporous or have teeth, ridges and / or grooves.
Le support chauffant peut ĆŖtre rĆ©alisĆ© en PTFE (TeflonĀ®) ou comporter un revĆŖtement de PTFE ou d'un matĆ©riau similaire.The heating support may be made of PTFE (TeflonĀ®) or have a coating of PTFE or similar material.
Dans un exemple de mise en oeuvre de l'invention, le support chauffant est fixe relativement Ć une partie de prĆ©hension du dispositif d'application.In an exemplary implementation of the invention, the heating support is fixed relative to a gripping portion of the application device.
Dans un autre exemple de mise en oeuvre de l'invention, le support chauffant est mobile relativement Ć une partie de prĆ©hension du dispositif d'application.In another example of implementation of the invention, the heating support is movable relative to a gripping portion of the application device.
Le support chauffant est par exemple mobile en translation. Cela peut permettre de diminuer l'encombrement du dispositif d'application en l'absence d'utilisation.The heating support is for example mobile in translation. This can reduce the size of the application device in the absence of use.
Le dispositif d'application peut Ć©galement ĆŖtre agencĆ© de telle sorte que le dĆ©placement du support chauffant relativement Ć la partie de prĆ©hension provoque l'Ć©jection de l'embout applicateur du support chauffant. Pour faciliter cette Ć©jection, l'embout applicateur peut par exemple comporter Ć sa base une surĆ©paisseur, par exemple sous la forme d'une collerette, venant prendre appui contre une paroi du dispositif d'application lorsque le support chauffant est dĆ©placĆ©.The application device may also be arranged such that the displacement of the heating support relative to the gripping portion causes ejection of the applicator tip of the heating support. To facilitate this ejection, the applicator tip may for example comprise at its base an extra thickness, for example in the form of a flange, coming to bear against a wall of the application device when the heating support is moved.
Le support chauffant peut encore ĆŖtre mobile en rotation, par exemple autour d'un axe de rotation perpendiculaire Ć son axe longitudinal, sur lui-mĆŖme ou autour de tout axe non confondu avec son axe longitudinal.The heating support may also be mobile in rotation, for example around an axis of rotation perpendicular to its longitudinal axis, on itself or around any axis not coincident with its longitudinal axis.
Le dispositif d'application peut encore comporter, dans une variante de mise en oeuvre de l'invention, un organe d'Ʃjection mobile relativement au support chauffant. Cet organe d'Ʃjection se prƩsente par exemple sous la forme d'un poussoir qui est dƩplacƩ par l'utilisateur pour chasser l'embout applicateur hors du support chauffant.The application device may also comprise, in an alternative embodiment of the invention, an ejection member movable relative to the heating support. This ejection member is for example in the form of a pusher which is moved by the user to drive the applicator tip out of the heating support.
Le support chauffant peut prƩsenter toute forme adaptƩe au maquillage recherchƩ.The heating support may have any form suitable for the desired makeup.
Le support chauffant peut prƩsenter un axe longitudinal qui est rectiligne ou non. Un axe longitudinal curviligne peut par exemple amƩliorer encore l'ergonomie.The heating support may have a longitudinal axis which is rectilinear or not. A curvilinear longitudinal axis can for example further improve the ergonomics.
L'axe longitudinal du support chauffant peut ĆŖtre confondu ou parallĆØle Ć l'axe longitudinal d'une partie de prĆ©hension du dispositif d'application, cette partie de prĆ©hension Ć©tant par exemple confondue avec un boĆ®tier du dispositif d'application.The longitudinal axis of the heating support may be coincident or parallel to the longitudinal axis of a gripping portion of the application device, this gripping portion being for example merged with a housing of the application device.
L'axe longitudinal du support peut encore ĆŖtre rectiligne et faire un angle avec l'axe longitudinal de la partie de prĆ©hension du dispositif d'application.The longitudinal axis of the support may be rectilinear and make an angle with the longitudinal axis of the gripping portion of the application device.
Le support chauffant peut prĆ©senter une section transversale qui dĆ©croĆ®t vers son extrĆ©mitĆ© distale. Cela peut faciliter l'enlĆØvement de l'embout applicateur.The heating support may have a cross section which decreases towards its distal end. This can facilitate the removal of the applicator tip.
Le support peut comporter une rĆ©sistance chauffante disposĆ©e Ć l'intĆ©rieur d'une enveloppe qui peut prĆ©senter une Ć©paisseur sensiblement constante, afin par exemple d'obtenir plus facilement une tempĆ©rature relativement homogĆØne sur toute la longueur du support chauffant. Le cas Ć©chĆ©ant, l'enveloppe peut prĆ©senter une Ć©paisseur de paroi variant longitudinalement en fonction d'un profil de tempĆ©rature recherchĆ©.The support may comprise a heating resistor disposed inside an envelope which may have a substantially constant thickness, for example to more easily obtain a relatively homogeneous temperature over the entire length of the heating support. Where appropriate, the casing may have a longitudinally varying wall thickness depending on a desired temperature profile.
L'Ć©paisseur de l'enveloppe peut par exemple dĆ©croĆ®tre en direction de l'extrĆ©mitĆ© distale du support chauffant, afin par exemple d'obtenir une tempĆ©rature plus Ć©levĆ©e en bout du support chauffant. En variante, l'Ć©paisseur de l'enveloppe peut ĆŖtre constante au moins sur la portion recouverte par la composition.The thickness of the envelope may, for example, decrease towards the distal end of the heating support, for example to obtain a higher temperature. high end of the heating support. Alternatively, the thickness of the envelope may be constant at least on the portion covered by the composition.
Le support chauffant peut prĆ©senter une surface extĆ©rieure de forme circulaire ou non en section transversale, par exemple polygonale, et peut ĆŖtre lisse ou non, prĆ©senter des stries ou non, ou tout autre relief.The heating support may have an outer surface of circular shape or not in cross section, for example polygonal, and may be smooth or not, have streaks or not, or any other relief.
La prƩsence de reliefs tels que des stries, notamment longitudinales, peut par exemple favoriser l'accrochage de la composition une fois ramollie ou liquƩfiƩe par la chaleur dƩgagƩe par le support chauffant.The presence of reliefs such as streaks, in particular longitudinal streaks, may, for example, promote the adhesion of the composition once softened or liquefied by the heat released by the heating support.
L'embout applicateur peut prƩsenter une section transversale intƩrieure qui est homothƩtique ou non de la section transversale extƩrieure du support chauffant.The applicator tip may have an internal cross section which is homothetic or not the outer cross section of the heating support.
L'embout applicateur peut prƩsenter une forme effilƩe et notamment comporter une pointe rƩtrƩcie, ce qui peut faciliter la rƩalisation d'un traitement cil par cil.The applicator tip may have a tapered shape and in particular have a narrowed tip, which may facilitate the production of an eyelash treatment by eyelash.
L'embout applicateur peut prƩsenter une surface extƩrieure de forme gƩnƩrale conique, sur au moins une portion de sa longueur.The applicator tip may have an outer surface of generally conical shape over at least a portion of its length.
L'extrĆ©mitĆ© distale de l'embout applicateur peut ĆŖtre arrondie.The distal end of the applicator tip may be rounded.
L'embout applicateur peut prĆ©senter Ć sa base une surĆ©paisseur, par exemple sous la forme d'une collerette, destinĆ©e par exemple Ć faciliter la prĆ©hension de l'embout applicateur par l'utilisateur et/ou l'enlĆØvement de l'embout applicateur du support chauffant. Cette surĆ©paisseur peut recouvrir une rĆ©gion non chauffĆ©e du dispositif d'application.The applicator tip may have at its base an extra thickness, for example in the form of a flange, intended for example to facilitate the gripping of the applicator tip by the user and / or the removal of the applicator tip of the applicator. heating support. This extra thickness can cover an unheated region of the application device.
L'embout applicateur peut prƩsenter une section transversale extƩrieure de forme circulaire ou non, par exemple polygonale, et/ou aplatie, avec des stries ou non.The applicator tip may have an outer cross section of circular shape or not, for example polygonal, and / or flattened, with streaks or not.

Le dispositif d'application 10 reprƩsentƩ aux
Dans une variante non reprĆ©sentĆ©e, la source Ć©lectrique est rechargeable et peut ĆŖtre rechargĆ©e par exemple en disposant le dispositif d'application sur un socle.In a variant not shown, the power source is rechargeable and can be recharged for example by arranging the application device on a base.
Dans une autre variante non reprĆ©sentĆ©e, la pile de 9V est remplacĆ©e par au moins une pile bĆ¢ton de 1,5 V, voire deux piles de 1,5 V disposĆ©es cĆ“te-Ć -cĆ“te, ou une pile bouton de 3 V.In another variant not shown, the 9V battery is replaced by at least one 1.5V stick battery, or two 1.5V batteries arranged side by side, or a 3V button cell.
Le dispositif d'application peut encore utiliser un accumulateur ou ĆŖtre alimentĆ© par le secteur.The application device can still use an accumulator or be powered by the mains.
Le dispositif d'application 10 peut comporter un organe 14 de commande du fonctionnement du support chauffant 11, se prƩsentant par exemple sous la forme d'un contacteur, par exemple un bouton-poussoir, permettant, lorsqu'enfoncƩ par l'utilisateur, d'alimenter Ʃlectriquement une rƩsistance chauffante 15, non apparente sur la
Le dispositif d'application 10 peut Ć©ventuellement comporter, comme illustrĆ©, un voyant lumineux 16 pour signaler Ć l'utilisateur la mise sous tension de la rĆ©sistance chauffante 15.The
La rĆ©sistance chauffante 15 peut ĆŖtre choisie de telle sorte que mĆŖme alimentĆ©e Ć©lectriquement en continu, la tempĆ©rature Ć la surface du support chauffant 11 reste infĆ©rieure, dans un environnement clos Ć 25 Ā°C, Ć une tempĆ©rature susceptible d'entraĆ®ner un risque de brĆ»lure de l'utilisateur en cas de contact accidentel, par exemple une tempĆ©rature de 90 Ā°C ou 95 Ā°C.The
En variante, par exemple afin de mieux contrĆ“ler la tempĆ©rature du support chauffant 11, le dispositif d'application 10 peut comporter un organe 17 de rĆ©gulation de la tempĆ©rature, par exemple sous la forme d'un thermostat Ć bilame ou d'un circuit Ć©lectronique de rĆ©gulation comportant par exemple une sonde de tempĆ©rature intĆ©grĆ©e au support chauffant 11.Alternatively, for example in order to better control the temperature of the
De prĆ©fĆ©rence, en fonctionnement, la tempĆ©rature de surface du support chauffant 11 reste comprise entre 45 Ā°C et 95 Ā°C, mieux 45 Ā°C et 90 Ā°C, encore mieux entre 55 et 65 Ā°C, mais on ne sort pas du cadre de la prĆ©sente invention lorsque la tempĆ©rature durant le fonctionnement est autre, notamment supĆ©rieure.Preferably, in operation, the surface temperature of the
De prĆ©fĆ©rence, la tempĆ©rature de surface varie de moins de 5 Ā°C lorsque l'on se dĆ©place sur la circonfĆ©rence du support chauffant en un point de sa longueur.Preferably, the surface temperature varies by less than 5 Ā° C as one moves about the circumference of the heating support at a point of its length.
Le support chauffant 11 peut recevoir dans un exemple de mise en oeuvre de l'invention un embout applicateur 20, comme illustrƩ sur les
Cet embout applicateur 20 comporte une composition de maquillage des cils prĆ©sentant une propriĆ©tĆ© qui varie en fonction de la tempĆ©rature, notamment un caractĆØre filant.This
Il s'agit par exemple d'une composition comportant au moins un polymĆØre rĆ©versible.This is for example a composition comprising at least one reversible polymer.
Le caractĆØre filant peut notamment ĆŖtre de dmax supĆ©rieur ou Ć©gal Ć 5 mm, mesurĆ© comme indiquĆ© ci-dessous.The running character may in particular be of d max greater than or equal to 5 mm, measured as indicated below.
Le caractĆØre filant de la composition est dĆ©terminĆ© Ć l'aide du texturomĆØtre vendu sous la dĆ©nomination TA X- T2i par la sociĆ©tĆ© RHEO, Ć©quipĆ© d'un mobile contrĆ“lĆ© en tempĆ©rature, ce mobile Ć©tant une cartouche chauffante en inox de rĆ©fĆ©rence Firerod DIV-STL (SociĆ©tĆ© Watlow, France), de diamĆØtre 3,17 mm et de longueur 60 mm, d'une puissance maximale de 40 W sous une tension de 24 V, avec un thermocouple type K loc C.The running characteristic of the composition is determined using the texturometer sold under the name TA X-T2i by the company RHEO, equipped with a temperature-controlled mobile, this mobile being a reference stainless steel heating cartridge Firerod DIV-STL (Watlow Company, France), with a diameter of 3.17 mm and a length of 60 mm, with a maximum power of 40 W at a voltage of 24 V, with a K-type thermocouple loc C.
La cartouche chauffante est alimentĆ©e par une source de courant continue et sa tempĆ©rature est rĆ©gulĆ©e par un contrĆ“leur PID TC 48 de la sociĆ©tĆ© Faucigny instrument (France). Un appendice de fixation a Ć©tĆ© crĆ©Ć© pour fixer le mobile contrĆ“lĆ© en tempĆ©rature sur le bras de mesure du texturomĆØtre.The heating cartridge is powered by a DC power source and its temperature is regulated by a
La mesure est faite sur des fils de composition obtenus en imposant un dĆ©placement vertical du mobile jusqu'au contact avec un Ć©chantillon de la composition puis, aprĆØs un temps d'attente au contact, en imposant un dĆ©placement vertical du mobile vers le haut. La composition ayant un caractĆØre filant Ć chaud, un fil se forme entre le mobile en phase de retrait et l'Ć©chantillon de la composition, ce fil devenant plus consistant sous l'effet du refroidissement Ć l'air ambiant. La mesure de dmax consiste en une mesure de la longueur de fils ainsi formĆ©s aprĆØs dĆ©tachement de la surface du mobile.The measurement is made on son of composition obtained by imposing a vertical displacement of the mobile to contact with a sample of the composition and, after a waiting time in contact, imposing a vertical movement of the mobile up. Since the composition has a hot-running character, a wire is formed between the mobile in the shrinkage phase and the sample of the composition, this wire becoming more consistent under the effect of cooling with ambient air. The measurement of d max consists of a measurement of the length of wires thus formed after detachment from the surface of the mobile.
Le protocole est le suivant :
- a) on prĆ©pare un Ć©chantillon de la composition en remplissant Ć son maximum une coupelle en inox de 2 mm d'Ć©paisseur et de 20 mm de diamĆØtre, l'excĆØs de composition Ć©tant arasĆ© en surface,
- b) on contrĆ“le la tempĆ©rature du mobile Ć 40 Ā°C,
- c) le mobile descend Ć une vitesse de 10 mm/s jusqu'au contact de la surface de la composition,
- d) le mobile est maintenu fixe pendant 10s puis est relevĆ© Ć une vitesse de 10 mm/s.
- a) a sample of the composition is prepared by filling to its maximum a stainless steel cup 2 mm thick and 20 mm in diameter, the excess composition being leveled at the surface,
- b) the temperature of the mobile is controlled at 40 Ā° C.,
- c) the mobile descends at a speed of 10 mm / s until contact with the surface of the composition,
- d) the mobile is held stationary for 10s and then raised at a speed of 10 mm / s.
Pendant la phase de retrait du mobile, un fil est formĆ© entre la composition et le mobile. Au fur et Ć mesure que le mobile est Ć©loignĆ© de la surface de la composition, le fil formĆ© refroidit et devient plus consistant. A partir d'une certaine Ć©longation, le fil se dĆ©tache du mobile.During the removal phase of the mobile, a wire is formed between the composition and the mobile. As the mobile is moved away from the surface of the composition, the formed wire cools and becomes more consistent. From a certain elongation, the wire is detached from the mobile.
La grandeur dmax (exprimĆ© en mm) correspond Ć la longueur du fil obtenu aprĆØs rupture, mesurĆ©e avec une rĆØgle graduĆ©e.The quantity d max (expressed in mm) corresponds to the length of the wire obtained after breaking, measured with a graduated rule.
La mesure du caractĆØre filant est rĆ©pĆ©tĆ©e trois fois pour la mĆŖme composition, en diffĆ©rents endroits de la coupelle, et une moyenne de Ā« filant Ā» dmax est calculĆ©e pour chaque composition.The measurement of the spinning character is repeated three times for the same composition, in different places of the cup, and a mean of "spinning" d max is calculated for each composition.
Les Ć©tapes b) Ć d) sont rĆ©pĆ©tĆ©es pour la mĆŖme composition Ć une tempĆ©rature de mobile fixĆ©e Ć l'Ć©tape b) respectivement de 50 Ā°C, de 60 Ā°C, de 70 Ā°C, de 80 Ā°C, de 90 Ā°C, de 100 Ā°C, de 110 Ā°C, de 120 Ā°C, de 130 Ā°C et de 140 Ā°C.Steps b) to d) are repeated for the same composition at a mobile temperature set in step b) respectively of 50 Ā° C, 60 Ā° C, 70 Ā° C, 80 Ā° C, 90 Ā° C , 100 Ā° C, 110 Ā° C, 120 Ā° C, 130 Ā° C and 140 Ā° C.

Dans l'exemple illustrƩ, le contacteur 430 est prƩsent sur la face de la bague qui est opposƩe au moyen de montage 420, et l'utilisateur peut transmettre les vibrations au support chauffant 11 en venant serrer entre deux doigts le dispositif d'application 10, la bague vibrante Ʃtant montƩe sur l'un de ces doigts.In the illustrated example, the
La prĆ©sence de vibrations lors de l'application peut ĆŖtre utile pour contrĆ“ler plus facilement l'application du produit et notamment casser Ć la longueur voulue les fils de produit qui sont formĆ©s en bout des cils. L'utilisateur peut par exemple Ć©tirer les fils de produit sans vibrations et dĆ©clencher les vibrations lorsque ceux-ci ont atteint la longueur souhaitĆ©e afin de les rompre.The presence of vibrations during application may be useful to control the application of the product more easily and in particular break the length of the product son that are formed at the end of the eyelashes. The user can for example stretch the son of product without vibrations and trigger the vibrations when they have reached the desired length to break them.
La mise en vibration du support chauffant peut ainsi permettre plus facilement d'allonger les cils sans avoir nĆ©cessairement Ć Ć©tirer rapidement les fils de produit, ce qui est une opĆ©ration difficilement reproductible. Les vibrations peuvent permettre d'opĆ©rer plus facilement la rupture des fils de produits aux dimensions souhaitĆ©es.The vibration of the heating support can thus make it easier to lengthen the eyelashes without necessarily having to rapidly stretch the son of product, which is an operation difficult to reproduce. The vibrations can make it easier to break the son of products to the desired dimensions.
L'utilisateur peut aussi, grĆ¢ce Ć l'invention, former une succession de petits paquets de produit en bout des cils, comme illustrĆ© sur la
Les vibrations peuvent favoriser l'adhĆ©rence de la composition fondue sur les cils, rendre l'allongement plus homogĆØne, et permettre un geste de maquillage plus lent et plus facilement reproductible.The vibrations can promote the adhesion of the melted composition on the eyelashes, make the elongation more homogeneous, and allow a makeup gesture that is slower and more easily reproducible.
Les vibrations peuvent Ʃgalement Ʃlargir la gamme de tempƩratures acceptables pour le maquillage.Vibrations can also broaden the acceptable temperature range for makeup.
La source vibrante peut ĆŖtre rĆ©alisĆ©e autrement qu'avec un moteur entraĆ®nant une masselotte excentrĆ©e, par exemple comporter un moteur entraĆ®nant un excentrique, un vibreur piĆ©zoĆ©lectrique ou Ć©lectromĆ©canique. La source vibrante peut comporter un moteur entraĆ®nant une roue dentĆ©e et un frotteur constituĆ© par exemple d'une lame Ć©lastique s'appliquant sur cette roue dentĆ©e.The vibrating source can be made otherwise than with a motor driving an eccentric flyweight, for example comprising a motor driving an eccentric, a piezoelectric or electromechanical vibrator. The vibrating source may comprise a motor driving a toothed wheel and a shoe constituted for example by an elastic blade applying to this toothed wheel.
La source vibrante, lorsqu'elle est amovible, peut comporter des dents. Ces dents sont par exemple orientƩes dans une direction opposƩe au support chauffant.The vibrating source, when removable, may have teeth. These teeth are for example oriented in a direction opposite to the heating support.
Le dispositif d'application peut comporter des dents Ć l'opposĆ© du support chauffant.The application device may have teeth opposite the heating support.
L'expression Ā« comportant un Ā» doit ĆŖtre comprise comme Ć©tant synonyme de Ā« comportant au moins un Ā» sauf si le contraire est spĆ©cifiĆ©.The phrase "with one" should be understood as being synonymous with "having at least one" unless the opposite is specified.
