Description

La présente invention se rapporte au domaine technique des dispositifs d'application de cire à épiler, dans lesquels la cire, stockée sous forme solide à température ambiante, doit être soumise à un flux thermique pour changer d'état et passer à un état au moins pâteux afin de pouvoir être appliquée.The present invention relates to the technical field of depilatory wax application devices, in which the wax, stored in solid form at room temperature, must be subjected to a heat flux in order to change state and change to at least one state. pasty so that it can be applied.

La présente invention concerne plus particulièrement un applicateur de cire à épiler comprenant un boîtier de préhension à l'intérieur duquel sont logés des moyens de chauffe, associés à des moyens de régulation thermique, destinés à faire fondre une charge de cire, un réservoir destiné à recueillir la cire fondue.The present invention relates more particularly to a depilatory wax applicator comprising a gripping housing inside which are housed heating means, associated with thermal regulation means, intended to melt a load of wax, a reservoir intended for collect the melted wax.

Quel que soit le type d'applicateur de cire à épiler considéré, la technique d'épilation par application d'une cire dépilatoire consiste à faire fondre une certaine quantité de cire, puis à appliquer à l'état fondu une couche de cette cire sur la zone à épiler. Après durcissement, c'est-à-dire après refroidissement, la pellicule de cire froide est retirée à l'aide de tous moyens appropriés, les poils étant alors extraits de la peau en raison de leur solidarisation avec la cire fondue.Whatever type of depilatory wax applicator is considered, the depilation technique by applying a depilatory wax consists in melting a certain amount of wax, then in applying a layer of this wax in the molten state. the area to be epilated. After hardening, that is to say after cooling, the cold wax film is removed using any suitable means, the hairs then being extracted from the skin due to their joining with the molten wax.

Pour mettre en oeuvre cette technique largement répandue, on connaît déjà des distributeurs de cire chaude prête à l'emploi, constitués d'un réservoir de cire chauffée par un moyen quelconque, par exemple par un appareil analogue à un chauffe-biberon. Ces dispositifs sont complétés par un simple rouleau distributeur de cire indépendant du réservoir, que l'utilisateur introduit dans la masse de cire afin de l'enduire d'une masse de cire. Ces appareils, d'une grande rusticité, s'avèrent ne plus correspondre aux besoins des utilisatrices de cire à épiler en raison notamment de nombreux inconvénients d'utilisation. Ainsi la température d'application de la cire est pratiquement incontrôlable, tout comme l'épaisseur d'application de cette couche. Ces appareils sont également considérés comme encombrants et donnent lieu à une opération d'épilation longue, fastidieuse, souvent salissante et impliquant en outre une surconsommation de cire.To implement this widely used technique, ready-to-use hot wax dispensers are already known, consisting of a wax reservoir heated by any means, for example by a device similar to a bottle warmer. These devices are completed by a simple wax distributor roller independent of the reservoir, which the user introduces into the mass of wax in order to coat it with a mass of wax. These devices, which are very rustic, turn out to no longer correspond to the needs of users of depilatory wax, in particular because of numerous drawbacks of use. Thus the temperature of application of the wax is practically uncontrollable, just like the thickness of application of this layer. These devices are also considered to be bulky and give rise to a long, tedious, often messy hair removal operation and moreover involving excessive consumption of wax.

Pour améliorer les dispositifs antérieurs mentionnés précédemment, il a déjà été proposé, notamment dans la demande de brevet FR-A-2520601, un ensemble applicateur comportant un boîtier pourvu de logements chauffants dans lesquels sont logés des applicateurs manuels destinés à être mis en oeuvre par l'utilisatrice. Les applicateurs sont pourvus d'un réservoir interne de cire dépilatoire, et d'un rouleau applicateur de cire. Un tel applicateur constitue bien évidemment une amélioration notable par rapport aux dispositifs antérieurs, mais il ne résout cependant pas complètement le problème essentiel de la maîtrise de l'application de la cire. En effet, le chauffage de la cire n'intervient que de manière discontinue dans le temps lorsque l'applicateur est dans le logement chauffant. Il s'avère en conséquence qu'après un certain temps d'application la température de la cire décroît rapidement et n'est en conséquence plus à un niveau favorable. Ceci entraîne une difficulté croissante dans l'application, et en particulier l'apparition d'un phénomène de filage de la cire influençant négativement la qualité de l'épilation. Cet inconvénient s'accompagne d'une surconsommation de cire et d'une application hétérogène ce qui en définitive conduit à un résultat dépilatoire non satisfaisant. Pour pallier en partie à ce problème, l'utilisatrice est alors obligée de remettre fréquemment l'applicateur dans les logements chauffants, ce qui allonge de manière inconsidérée le temps consacré à l'opération d'épilation, sans pour autant garantir une meilleure maîtrise de la température de la cire ni au demeurant un meilleur résultat final.To improve the prior devices mentioned above, it has already been proposed, in particular in patent application FR-A-2520601, an applicator assembly comprising a housing provided with heating housings in which are housed manual applicators intended to be implemented by the user. The applicators are provided with an internal depilatory wax reservoir and a wax applicator roller. Such an applicator obviously constitutes a significant improvement compared to the prior devices, but it does not however completely solve the essential problem of controlling the application of the wax. In fact, the heating of the wax only takes place discontinuously over time when the applicator is in the heating housing. It therefore turns out that after a certain time of application the temperature of the wax decreases rapidly and is therefore no longer at a favorable level. This leads to an increasing difficulty in the application, and in particular the appearance of a phenomenon of spinning of the wax negatively influencing the quality of the epilation. This drawback is accompanied by an overconsumption of wax and a heterogeneous application, which ultimately leads to an unsatisfactory depilatory result. To partially alleviate this problem, the user is then obliged to frequently put the applicator back into the heated accommodation, which thoughtlessly lengthens the time devoted to the hair removal operation, without however ensuring better control of the temperature of the wax or, moreover, a better final result.

Il a ainsi été proposé, pour remédier en partie au défaut des ensembles applicateurs séparant le réservoir chauffant de cire de l'unité d'application, de réaliser, par exemple tel que cela est décrit dans la demande de brevet EP-A-0368698 un applicateur manuel comportant dans un même boîtier un réservoir de cire, une résistance de chauffe et un rouleau applicateur. Pour améliorer la facilité d'application de la cire, mais également pour tenter de maîtriser au mieux la température de la cire, il est prévu de munir le rouleau applicateur d'un moyen de chauffage autonome. Un tel dispositif assure une certaine maîtrise de la température d'application de la cire et réduit d'une certaine manière le risque d'apparition du phénomène de filage mentionné précédemment. La présence d'un moyen de chauffe directement dans le rouleau applicateur peut être à l'origine d'un risque de surchauffe de la cire ou de brûlure de la peau de l'utilisatrice. En outre un tel dispositif s'avère être d'une réalisation délicate dans la mesure où il nécessite le montage de deux moyens de chauffe séparés dans un boîtier. En définitive la fiabilité d'un tel dispositif n'est pas assurée et son coût s'avère élevé.It has thus been proposed, to partially remedy the defect of the applicator assemblies separating the wax heating reservoir from the application unit, to produce, for example as described in patent application EP-A-0368698 a manual applicator comprising in one housing a wax reservoir, a heating resistor and an applicator roller. To improve the ease of application of the wax, but also to try to control the temperature of the wax as well as possible, it is planned to provide the applicator roller with an independent heating means. Such a device ensures a certain control over the temperature of application of the wax and in a certain way reduces the risk of the appearance of the spinning phenomenon mentioned above. The presence of a heating medium directly in the applicator roller can be the source of a risk of overheating the wax or burning of the user's skin. In addition, such a device turns out to be a delicate embodiment insofar as it requires the mounting of two separate heating means in a housing. Ultimately, the reliability of such a device is not guaranteed and its cost is high.

Un problème reste par ailleurs insurmonté dans les différents types d'applicateurs connus. En effet, les applicateurs décrits ci-haut utilisent tous la force gravitationnelle pour faire descendre la cire chauffée à travers un orifice ou une fente d'où elle s'échappe pour être par la suite appliquée par un rouleau applicateur. Dès que le boîtier n'est plus positionné de façon à faciliter l'écoulement de la cire, l'approvisionnement devient irrégulier, ce qui occasionne l'application d'une couche discontinue dont l'épaisseur varie d'un point à l'autre. Une telle couche est évidemment inadéquate pour offrir des résultats d'épilation satisfaisants. Ce phénomène est d'autant plus important si on souhaite épiler des régions présentant des surfaces peu étendues, difficiles d'accès ou encore des régions où la peau est particulièrement sensible, comme par exemple le contour des sourcils, la moustache, le menton, les aisselles, le maillot, le bikini, etc. L'épilation de ces différentes zones nécessite un applicateur particulièrement maniable, présentant une multiplicité de possibilités de positionnement dans l'espace et permettant la dépose d'une couche de cire uniforme et régulière, d'épaisseur bien définie et contrôlée.A problem also remains insurmounted in the different types of known applicators. Indeed, the applicators described above all use the gravitational force to bring the heated wax down through an orifice or a slot from which it escapes to be subsequently applied by an applicator roller. As soon as the casing is no longer positioned so as to facilitate the flow of the wax, the supply becomes irregular, which causes the application of a discontinuous layer whose thickness varies from one point to another. . Such a layer is obviously inadequate to offer satisfactory hair removal results. This phenomenon is all the more important if one wishes to depilate regions with small areas, difficult to access or regions where the skin is particularly sensitive, such as for example the eyebrow contour, the mustache, the chin, the armpits, bikini line, bikini, etc. Depilating these different areas requires a particularly handy applicator, presenting a multiplicity of possibilities of positioning in space and allowing the deposition of a uniform and regular layer of wax, of well defined and controlled thickness.

L'objet de la présente invention vise en conséquence à remédier aux inconvénients mentionnés précédemment, et à fournir un applicateur de cire à épiler dont le mode d'application est indépendant de la force gravitationnelle.The object of the present invention therefore aims to remedy the drawbacks mentioned above, and to provide a depilatory wax applicator whose mode of application is independent of the gravitational force.

Un autre objet de l'invention vise à foumir un applicateur de cire à épiler permettant une maîtrise et un contrôle optimal de la couche de cire appliquée.Another object of the invention is to provide a depilatory wax applicator allowing optimal control and control of the layer of wax applied.

Un autre objet de l'invention vise à foumir un applicateur de cire à épiler permettant l'application d'une couche régulière et uniforme, peu importe la position de l'applicateur.Another object of the invention is to provide a depilatory wax applicator allowing the application of a regular and uniform layer, regardless of the position of the applicator.

Un autre objet de l'invention vise à foumir un applicateur de cire à épiler fonctionnant indépendamment de son orientation dans l'espace, et possédant par le fait même plusieurs degrés de liberté.Another object of the invention aims to provide a depilatory wax applicator operating independently of its orientation in space, and thereby having several degrees of freedom.

Un autre objet de l'invention vise à foumir un applicateur de cire à épiler dont les différentes pièces sont particulièrement simples à réaliser et à monter.Another object of the invention aims to provide a depilatory wax applicator, the different parts of which are particularly simple to produce and to assemble.

Un autre objet de l'invention est de fournir un applicateur de cire à épiler d'utilisation facilitée lors du chargement de la cire et lors du démontage et du nettoyage.Another object of the invention is to provide a depilatory wax applicator of easy use when loading the wax and during disassembly and cleaning.

Les objets assignés à l'invention sont atteints à l'aide d'un applicateur de cire à épiler comprenant un boîtier de préhension à l'intérieur duquel sont logés des moyens de chauffe, associés à des moyens de régulation thermique, destinés à faire fondre une charge de cire, un réservoir destiné à recueillir la cire fondue caractérisé en ce que ledit applicateur comprend des moyens d'acheminement de ladite cire dont au moins une portion baigne dans la cire lorsque celle-ci est fondue et une autre portion circule hors du boîtier, lesdits moyens permettant l'acheminement de la cire fondue, indépendamment de la position dudit applicateur, depuis le réservoir vers la portion des moyens d'acheminement circulant hors du boîtier par l'entremise d'une ouverture calibrée prévue au niveau de l'embout du boîtier.The objects assigned to the invention are achieved using a depilatory wax applicator comprising a gripping box inside which are housed heating means, associated with thermal regulation means, intended to melt a charge of wax, a reservoir intended to collect the molten wax characterized in that said applicator comprises means for conveying said wax of which at least a portion is immersed in the wax when the latter is melted and another portion circulates outside the housing, said means allowing the delivery of the molten wax, regardless of the position of said applicator, from the reservoir to the portion of the delivery means circulating outside the housing via a calibrated opening provided at the case end cap.

L'applicateur de cire à épiler illustré aux figures 1 à 4 comporte un boîtier 3 réalisé par exemple en un matériau plastique, ledit boîtier présentant une forme générale allongée d'axe longitudinal x-x'. Le boîtier 3 est de section transversale quelconque et par exemple sensiblement circulaire, et constitue de manière avantageuse un moyen de préhension susceptible de permettre à l'utilisatrice de s'en saisir manuellement. A l'intérieur du boîtier 3 est logé un réservoir 6, réalisé de préférence en un matériau bon conducteur de la chaleur, et destiné à assurer le stockage d'une part de la cire 5, et d'autre part des moyens d'acheminement 1 de ladite cire. Avantageusement, le réservoir 6 est réalisé en aluminium et s'étend sensiblement sur toute la partie centrale du boîtier 3 selon l'axe x-x'.The depilatory wax applicator illustrated in FIGS. 1 to 4 comprises a housing 3 made for example of a plastic material, said housing having a generally elongated shape with a longitudinal axis x-x '. The housing 3 is of any cross section and for example substantially circular, and advantageously constitutes a gripping means capable of allowing the user to grasp it manually. Inside the housing 3 is housed a reservoir 6, preferably made of a material which is a good conductor of heat, and intended to ensure the storage on the one hand of the wax 5, and on the other hand of the conveying means 1 of said wax. Advantageously, the reservoir 6 is made of aluminum and extends substantially over the entire central part of the housing 3 along the axis x-x '.

Selon la forme d'exécution illustrée, les moyens d'acheminement 1 comprennent tout d'abord une bande d'acheminement 11, réalisée par exemple en matériau de type élastomère, avantageusement armé d'une âme de polyester. La bande 11 circule autour de moyens de roulements, comme par exemple des galets 12. Selon une forme d'exécution préférentielle de l'invention, deux galets 12 sont maintenus de part et d'autre d'un support 13, de façon à pouvoir chacun tourner librement autour d'un axe 9 orienté selon l'axe y-y' sensiblement perpendiculaire à l'axe x-x' du boîtier 3. Le support 13 est avantageusement fabriqué en matériau conducteur, tel l'aluminium. La disposition des galets 12 sur le support 13 est prévue de façon à définir un entraxe donné conférant à la bande d'acheminement 11 une tension favorisant l'acheminement de la cire. Selon diverses variantes, il est possible de varier ou d'ajuster la tension de la bande 11 par exemple à l'aide d'un système vis/écrou ou encore au moyen d'un ressort comprimé entre le support 13 et l'axe d'un des galets.According to the illustrated embodiment, the conveying means 1 firstly comprise a conveying strip 11, made for example of material of the elastomer type, advantageously reinforced with a polyester core. The strip 11 circulates around rolling means, such as for example rollers 12. According to a preferred embodiment of the invention, two rollers 12 are held on either side of a support 13, so as to be able to each rotate freely around an axis 9 oriented along the axis yy 'substantially perpendicular to the axis xx' of the housing 3. The support 13 is advantageously made of conductive material, such as aluminum. The arrangement of the rollers 12 on the support 13 is provided so as to define a given center distance giving the conveyor belt 11 a tension favoring the conveyance of the wax. According to various variants, it is possible to vary or adjust the tension of the strip 11 for example using a screw / nut system or even by means of a compressed spring between the support 13 and the axis d 'one of the pebbles.

La surface de la bande d'acheminement peut être lisse ou peut comporter différents types de motifs en relief, disposés régulièrement le long de la bande. La figure 2 illustre un exemple où la bande comporte une multitudes de bandes parallèles alignées selon l'axe des y-y' des moyens de roulement, réparties régulièrement le long du parcours de la bande. L'acheminement de la cire est ainsi facilité. Selon d'autres variantes, il est prévu d'utiliser une bande comportant au moins une creusure disposée le long de son parcours selon l'axe x-x'. Une telle creusure permet d'augmenter localement l'épaisseur de la couche de cire afin d'augmenter sa résistance mécanique pendant la phase d'arrachage.The surface of the conveyor belt may be smooth or may include different types of relief patterns, arranged regularly along the belt. FIG. 2 illustrates an example where the strip comprises a multitude of parallel strips aligned along the axis of the y-y 'of the rolling means, distributed regularly along the path of the strip. The routing of the wax is thus facilitated. According to other variants, it is planned to use a strip comprising at least one recess arranged along its path along the axis x-x '. Such a recess makes it possible to locally increase the thickness of the wax layer in order to increase its mechanical strength during the tearing-out phase.

L'applicateur comprend avantageusement des moyens de guidage latéral de la bande d'acheminement, évitant tout glissement ou dérapage latéral de celle-ci. Il peut s'agir d'une nervure centrale 15 coopérant avec une fente de guidage 15a correspondante pratiquée dans les galets 12. Selon une variante non montrée, des rebords latéraux disposés sur la périphérie externe des galets jouent le même rôle.The applicator advantageously comprises means for lateral guidance of the conveyor belt, avoiding any lateral sliding or slipping of the latter. It may be a central rib 15 cooperating with a corresponding guide slot 15a formed in the rollers 12. According to a variant not shown, lateral flanges disposed on the outer periphery of the rollers play the same role.

Selon la forme d'exécution illustrée, les moyens d'acheminement 1 et/ou le logement 14 contenant la charge de cire sont amovibles, de préférence par glissement ou coulissement du support 13 dans le réservoir 6 de façon à permettre l'extraction ou l'insertion par l'embout 8 du boîtier 3, comme on peut le voir à la figure 2. Cette particularité facilite le chargement de la cire. Ainsi, on peut insérer par exemple une charge de cire de type connu dans un logement 14 prévu à cette fin dans le corps central du support 13. Un éventuel moyen de blocage, de type connu, assure le maintien des moyens 1 dans le boîtier. Un tel moyen de blocage (non montré) peut être constitué par exemple d'un pointeau à ressort, d'une vis à deux positions, ou tout autre moyen de blocage classique.According to the illustrated embodiment, the conveying means 1 and / or the housing 14 containing the wax charge are removable, preferably by sliding or sliding of the support 13 in the tank 6 so as to allow the extraction or the 'insertion by the nozzle 8 of the housing 3, as can be seen in Figure 2. This feature facilitates the loading of the wax. Thus, it is possible, for example, to insert a load of wax of known type into a housing 14 provided for this purpose in the central body of the support 13. A possible locking means, of known type, maintains the means 1 in the housing. Such a locking means (not shown) can consist for example of a spring needle, a two-position screw, or any other conventional locking means.

Le réservoir 6 est en relation thermique avec des moyens de chauffe 4, constitués par exemple d'une résistance électrique ou d'une CTP entourant au moins partiellement le réservoir 6 ou, tel que cela est montré à la figure 1, montée solidaire d'une paroi dudit réservoir 6. Le moyen de chauffe 4 est de manière classique associé à des moyens de régulation thermique tels qu'un thermostat et un fusible. Selon diverses variantes, d'autres moyens de chauffe peuvent être utilisés, tels une cartouche chauffante, une résistance blindée avec ou sans asservissement thermique, une ampoule halogène ou à incandescence, tous ces moyens étant de types connus. Dans les deux derniers cas, la régulation peut être réalisée par éloignement de la source lumineuse du corps de chauffe, ce dernier étant alors avantageusement réalisé en matériau transparent, comme par exemple le verre, le polycarbonate, le PMMA ou le polyamide 11 ou 12.The tank 6 is in thermal relation with heating means 4, consisting for example of an electrical resistance or a PTC at least partially surrounding the tank 6 or, as shown in FIG. 1, mounted integral with a wall of said tank 6. The heating means 4 is conventionally associated with thermal regulation means such as a thermostat and a fuse. According to various variants, other heating means can be used, such as a heating cartridge, an armored resistor with or without thermal control, a halogen or incandescent bulb, all of these means being of known types. In the latter two cases, the regulation can be carried out by moving the light source away from the heating body, the latter then advantageously being made of transparent material, such as for example glass, polycarbonate, PMMA or polyamide 11 or 12.

Avantageusement, l'applicateur conforme à l'invention est pourvu d'un témoin d'utilisation 7, disposé sur le boîtier 3, informant l'utilisatrice que la température d'application de la cire est atteinte. Il peut s'agir par exemple d'un témoin basé sur le changement de couleur d'une encre réversible à une température donnée. Selon d'autres variantes, d'autres moyens indiquant que la température d'utilisation est atteinte peuvent être utilisés, comme par exemple un compteur de temps associé à un signal sonore ou visuel de type connu, tel qu'un affichage par LCD, LED ou autre.Advantageously, the applicator according to the invention is provided with a usage indicator 7, placed on the housing 3, informing the user that the application temperature of the wax has been reached. It may for example be a witness based on the color change of a reversible ink at a given temperature. According to other variants, other means indicating that the operating temperature has been reached can be used, such as for example a time counter associated with an audible or visual signal of known type, such as a display by LCD, LED Or other.

L'ensemble du système électrique y compris les connexions électriques et les moyens de blocage du cordon d'alimentation 10 est de préférence monté sur une bride support 2 logée entre le fond du boîtier et le bord du réservoir.The entire electrical system including the electrical connections and the means for blocking the power cord 10 is preferably mounted on a support flange 2 housed between the bottom of the housing and the edge of the tank.

Le fonctionnement de l'applicateur selon l'invention est décrit ci-après.The operation of the applicator according to the invention is described below.

L'utilisatrice saisit l'applicateur par son boîtier 3, libère l'éventuel moyen de blocage, sort le moyen d'acheminement 1 par sa portion proéminente du boîtier et installe une charge de cire 5 dans le logement 14 prévu à cet effet dans le support 13. L'ensemble 1 est par la suite réintroduit dans le boîtier. Dès le branchement ou dès la sélection de l'interrupteur sur la position de fonctionnement, les moyens de chauffe 4 sont activés. La température de la cire augmente; la cire ramollie, puis fond. Elle se répartie alors dans le réservoir 6, le long d'au moins une des parois de celui-ci, suivant l'orientation de l'applicateur, comme illustré à la figure 3. La bande d'acheminement longeant les parois du réservoir, la cire entre en contact avec ladite bande. Dès que celle-ci est entraînée en circulation, par exemple en déplaçant l'applicateur le long d'une surface où l'on souhaite déposer une couche de cire, ladite cire est entraînée par la bande vers l'extérieur du boîtier, selon le sens de déplacement de la bande. La cire présente sur la portion de bande hors du boîtier se dépose alors sur la surface d'application, notamment la surface à épiler. Le déplacement de l'applicateur contre la surface d'application entraîne donc la circulation de la bande qui achemine la cire fondue depuis le réservoir vers la surface d'application. L'ouverture calibrée 8a permet la dépose d'une couche régulière et uniforme.The user grasps the applicator by its casing 3, releases the possible locking means, takes out the conveying means 1 through its protruding portion of the casing and installs a wax charge 5 in the housing 14 provided for this purpose in the support 13. The assembly 1 is subsequently reintroduced into the housing. Upon connection or upon selection of the switch in the operating position, the heating means 4 are activated. The temperature of the wax increases; the softened wax, then melts. It is then distributed in the reservoir 6, along at least one of the walls of the latter, according to the orientation of the applicator, as illustrated in FIG. 3. The conveyor belt running along the walls of the reservoir, the wax comes into contact with said strip. As soon as it is driven into circulation, for example by moving the applicator along a surface where it is desired to deposit a layer of wax, said wax is entrained by the strip towards the outside of the case, according to the direction of movement of the strip. The wax present on the strip portion outside the housing is then deposited on the application surface, in particular the surface to be depilated. The movement of the applicator against the application surface therefore results in the circulation of the strip which conveys the molten wax from the reservoir to the application surface. The calibrated opening 8a allows the deposit of a regular and uniform layer.

Lorsque le réservoir est vide, une nouvelle charge de cire peut à nouveau être installée, tel que décrit ci-haut.When the tank is empty, a new wax charge can be installed again, as described above.

Une variante d'exécution avantageuse de la présente invention est illustrée aux figures 5 et 6. Afin de rendre l'utilisation de l'applicateur plus aisée et confortable et afin de faciliter l'acheminement de la cire, des moyens de motorisation 16, 17, 18 et 19 de type connu sont prévus. Ainsi, par exemple, un moteur 16 DC ou pas à pas relié à un ensemble de transmission 17 entraînant un galet d'entraînement coopérant avec la bande d'acheminement 11, permet l'avancement automatique de la bande. Le moteur 16 est disposé dans le boîtier 3, de préférence hors du réservoir 6 et un ensemble de transmission, par exemple à courroie, transmet le mouvement rotatif au galet 18, disposé dans le réservoir 6, contre la courroie. Un axe traversant de façon étanche une paroi du support 13 complète la chaîne d'entraînement.An advantageous alternative embodiment of the present invention is illustrated in FIGS. 5 and 6. In order to make the use of the applicator easier and comfortable and in order to facilitate the delivery of the wax, motorization means 16, 17 , 18 and 19 of known type are provided. Thus, for example, a DC or stepper motor 16 connected to a transmission assembly 17 driving a drive roller cooperating with the conveyor belt 11, allows the automatic advancement of the belt. The motor 16 is arranged in the housing 3, preferably outside the reservoir 6 and a transmission assembly, for example with a belt, transmits the rotary movement to the roller 18, disposed in the reservoir 6, against the belt. An axis sealingly passing through a wall of the support 13 completes the drive chain.

Ces moyens de motorisation permettent l'avancement automatique de la bande, par exemple en début de cycle, avant que celle-ci soit couverte de cire. Pendant l'application, les moyens d'avancement automatique de la courroie permettent à la bande de circuler à une vitesse constante, ce qui contribue à l'application d'une couche uniforme. Ce même moyen procure également l'avantage d'éliminer tout effort pour entraîner la bande et donc pour appliquer la cire. Cette particularité est particulièrement avantageuse pour les régions sensibles à épiler.These motorization means allow the automatic advancement of the strip, for example at the start of the cycle, before it is covered with wax. During application, the automatic belt advancement means allow the strip to circulate at a constant speed, which contributes to the application of a uniform layer. This same means also provides the advantage of eliminating any effort to drive the strip and therefore to apply the wax. This feature is particularly advantageous for regions sensitive to epilation.

Selon d'autres variantes d'exécution, non montrées, on ajoute un ou plusieurs galets 12 additionnels pour l'entraînement de la courroie. Selon le nombre de galets ajoutés, on a la possibilité de modifier le parcours de la courroie, pour obtenir un parcours de forme quelconque, par exemple triangulaire ou même sensiblement circulaire.According to other variant embodiments, not shown, one or more additional rollers 12 are added for driving the belt. Depending on the number of pebbles added, it is possible to modify the path of the belt, to obtain a path of any shape, for example triangular or even substantially circular.

Selon une autre variante, les moyens d'acheminement 1 sont constitués d'une bande ou ruban comprenant éventuellement une série de godets. Comme dans la forme d'exécution illustrée aux figures 3 et 4, au moins une portion de la bande baigne dans la cire fondue et une autre portion circule hors du boîtier.According to another variant, the conveying means 1 consist of a strip or ribbon possibly comprising a series of buckets. As in the embodiment illustrated in Figures 3 and 4, at least a portion of the strip is immersed in the molten wax and another portion flows out of the housing.
