Description

La présente invention se rapporte au domaine technique général des dispositifs d'application de produits thermofusibles, tels que la cire à épiler, les onguents, les crèmes, voire même les colles ou vernis, dans lesquels le produit stocké sous forme solide à température ambiante , doit être soumis à un flux thermique pour changer d'état et passer à un état au moins pâteux afin de pouvoir être appliqué.The present invention relates to the general technical field devices for applying hot-melt products, such as depilatory wax, ointments, creams, or even glues or varnishes, in which the product stored in solid form at room temperature, must be subjected to a heat flux to change state and go to an at least pasty state in order to can be applied.

La présente invention concerne plus particulièrement un applicateur de produits thermofusibles, en particulier de cire à épiler, comportant un boítier associé à un moyen de préhension, un réservoir du produit à appliquer en relation thermique avec des moyens de chauffe, et au moins un rouleau applicateur disposé au voisinage d'un orifice de sortie du réservoir.The present invention relates more particularly to an applicator of hot-melt products, in particular depilatory wax, comprising a housing associated with a gripping means, a reservoir of the product to be applied in relation thermal with heating means, and at least one applicator roller disposed in the vicinity of an outlet opening of the tank.

La présente invention concerne également de manière avantageuse une pince d'extraction pour un rouleau applicateur monté sur un applicateur conforme à l'invention, ainsi qu'un ensemble d'application de produits thermofusibles comportant l'applicateur de produits thermofusibles lui-même associé à la pince d'extraction. Par produits thermofusibles il convient d'entendre au sens de l'invention, tous les types de produits susceptibles de prendre à température ambiante, un état physique solide, voire semi-solide ou pâteux, mais susceptibles sous l'action de la chaleur de changer d'état physique pour tendre vers un état liquide susceptible de permettre son étalement sous forme de couches minces. L'invention vise plus particulièrement à protéger un applicateur de cire à épiler, mais il est bien évident que l'applicateur de produits thermofusibles conforme à l'invention n'est nullement limité à cette utilisation spécifique, et que des produits thermofusibles tels que des cires ou des colles peuvent être appliqués à l'aide de l'applicateur conforme à l'invention. The present invention also advantageously relates to extraction pliers for an applicator roller mounted on an applicator according to the invention, as well as a set of product applications hot melt including the hot melt applicator itself associated with the extraction clamp. By hot melt products should be understood within the meaning of the invention, all types of products liable to take room temperature, a solid, even semi-solid or pasty physical state, but susceptible to heat change from physical state to tender towards a liquid state capable of allowing its spreading in the form of thin layers. The invention more particularly aims to protect an applicator of depilatory wax, but it is quite obvious that the product applicator hot melt according to the invention is in no way limited to this use specific, and that hot-melt products such as waxes or glues can be applied using the applicator according to the invention.

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 and then apply a melt of this wax on the area to be depilated. After hardening, i.e. after cooling, the cold wax film is removed using any suitable means, the hairs then being extracted from the skin due to their attachment to the melted wax.

Pour mettre en oeuvre cette technique largement répandue, on connaít déjà des distributeurs de cire chaude prêtes 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 ainsi d'ailleurs que l'épaisseur d'application de la couche de cire. Ces appareils sont également considérés comme encombrants et donnent lieu à une opération d'épilation longue, fastidieuse, souvent salissante et impliquant en outre une sur-consommation de cire.To implement this widely used technique, we already know ready-to-use hot wax dispensers, consisting of a wax tank heated by any means, for example by an appliance analogous to a bottle warmer. These devices are supplemented by a simple wax distributor roller independent of the reservoir, which the user introduces in the wax mass in order to coat it with a wax mass. These devices, of a very hardy, appear to no longer correspond to the needs of users of depilatory wax due in particular to numerous disadvantages of use. So the application temperature of the wax is practically uncontrollable as well than the application thickness of the wax layer. These devices are also considered bulky and give rise to a hair removal operation long, tedious, often messy and also involves over-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 boítier 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 maítrise de la température d'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 décroít rapidement et n'est en conséquence plus à un niveau de température favorable. Ceci entraíne 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 sur-consommation 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 maítrise de la température de la cire ni au demeurant un meilleur résultat final.To improve the previous devices mentioned above, it has already been proposed, in particular in patent application FR-A-2520601, a applicator assembly comprising a housing provided with heating housings in which are housed manual applicators intended to be implemented by the wearer. Applicators have an internal wax reservoir depilatory, and a wax applicator roller. Such an applicator constitutes well obviously a noticeable improvement over previous devices but it does not, however, completely solve the essential problem of mastery of the temperature of application of the wax. Indeed, the heating of the wax does not intervene only discontinuously over time when the applicator is in the heated accommodation. It turns out that after a while of application the temperature of the wax decreases rapidly and is therefore more at a favorable temperature level. This causes increasing difficulty in the application, and in particular the appearance of a wax spinning phenomenon negatively influencing the quality of hair removal. This drawback is accompanied an overconsumption of wax and a heterogeneous application which definitive leads to an unsatisfactory depilatory result. To partially overcome this problem the user is then obliged to frequently replace the applicator in heated accommodation, which thoughtlessly lengthens time dedicated to the hair removal operation, without guaranteeing better control of the temperature of the wax nor, 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 boítier 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 maítriser 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 maítrise 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 séparé dans un boítier. 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 in the assemblies applicators separating the wax heating tank from the application unit, carry out, for example as described in patent application EP-A-0368698 a manual applicator comprising in one housing a reservoir of wax, a heating element and an applicator roller. To improve ease application of the wax, but also to try to control the temperature of the wax, it is planned to provide the applicator roller with a means of autonomous heating. Such a device ensures a certain control of the wax application temperature and somehow reduces the risk appearance of the previously mentioned spinning phenomenon. The presence of a heating medium directly in the applicator roller may be the cause risk of overheating the wax or burning the wearer's skin. In besides such a device turns out to be a delicate realization insofar as it requires the mounting of two separate heating means in a housing. In the reliability of such a device is definitely not guaranteed and its cost is high.

On connaít par ailleurs du document EP-0380391, un distributeur de fluide tels une crème ou un onguent, appliqué sur la peau sans chauffage préalable. Le distributeur selon ce document comporte un rouleau applicateur monté amovible sur le boítier. Ce document ne décrit pas un applicateur de produit thermofusible.We also know from document EP-0380391, a fluid distributor such as a cream or ointment, applied to the skin without prior heating. The dispenser according to this document includes a removable applicator roller on the housing. This document does not describe a hot melt applicator.

L'objet de la présente invention vise en conséquence à remédier aux inconvénients mentionnés précédemment, et à fournir un applicateur de produits thermofusibles dont la conception et la réalisation sont particulièrement simplifiées, tout en permettant une maítrise et un contrôle optimal de la température d'application du produit thermofusible.The object of the present invention therefore aims to remedy to the disadvantages mentioned above, and to provide an applicator for hot-melt products whose design and production are particularly simplified, while allowing control and optimal control of the application temperature of the hot-melt product.

Un autre objet de l'invention vise à fournir un applicateur de produits thermofusibles dont les différentes pièces sont particulièrement simples à réaliser et à monter.Another object of the invention aims to provide a product applicator hot-melt whose individual parts are particularly simple to make and to go up.

Un autre objet de l'invention est de fournir un applicateur de produits thermofusibles d'utilisation facilitée lors de son chargement en produits thermofusibles et lors de son démontage et de son nettoyage.Another object of the invention is to provide a product applicator easy to use hot-melt when loading products and when dismantling and cleaning it.

Le réservoir 2 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 2 ou, tel que cela est montré à la Figure 1, montée solidaire d'une paroi dudit réservoir 2.The hot melt applicator shown in Figure 1 is more particularly intended for the application of depilatory wax and includes a housing 1 made for example of a plastic material, said housing having a shape general elongated longitudinal axis x-x '. The housing 1 is of cross section any and for example substantially circular, and constitutes advantageous a gripping means capable of allowing the user to enter it manually. Inside the housing 1 is housed a tank 2, made in a material which is a good conductor of heat, and intended to ensure the storage of the hot melt product to be applied. Advantageously, the reservoir 2 is made in aluminum, extends substantially over the entire central part of the housing 1 according to the axis x-x 'and has a bottom 2a and an upper opening 2b. Advantageously, the reservoir 2 is provided in its central zone with a fin 3 of heat diffusion extending into the internal volume of said tank from from the bottom 2a. The tank 2 is in thermal relation with heating means 4, consisting for example of an electrical resistance or a PTC surrounding at at least partially the tank 2 or, as shown in Figure 1, mounted integral with a wall of said tank 2.

Le moyen de chauffe 4 est de manière classique associé à des moyens de régulation thermique tels qu'un thermostat 5 et un fusible 6. Avantageusement l'applicateur conforme à l'invention est pourvu, d'un voyant 7 de contrôle d'alimentation électrique visible de l'extérieur par l'intermédiaire d'une lumière ménagée à travers la paroi du boítier 1. L'ensemble du système électrique y compris les connexions électriques et les moyens de blocage du cordon d'alimentation (non montrés aux figures) est de préférence monté sur une bride support 8 logée dans la partie inférieure du boítier 1, sous le fond 2a du réservoir 2.The heating means 4 is conventionally associated with thermal regulation means such as a thermostat 5 and a fuse 6. Advantageously, the applicator according to the invention is provided with an indicator 7 power supply control visible from the outside via a light provided through the wall of the housing 1. The whole system electrical including electrical connections and locking means of the power cord (not shown in the figures) is preferably mounted on a support flange 8 housed in the lower part of the housing 1, under the bottom 2a of the tank 2.

La zone supérieure du boítier 1 est avantageusement constituée par une tête 11 par exemple vissée sur la partie supérieure du réservoir 2 et venant surmonter ladite partie supérieure ainsi que l'ouverture supérieure 2b du réservoir 2. L'extrémité supérieure 11b de la tête 11 délimite ainsi une enveloppe géométrique constituant l'orifice de sortie proprement dit de la cire.The upper zone of the housing 1 is advantageously constituted by a head 11 for example screwed onto the upper part of the tank 2 and coming overcome said upper part as well as the upper opening 2b of the reservoir 2. The upper end 11b of the head 11 thus delimits an envelope geometric constituting the actual outlet of the wax.

L'applicateur de produit thermofusible conforme à l'invention comporte également un rouleau applicateur 15 d'axe de révolution longitudinal y-y' disposé dans l'orifice de sortie du réservoir 2 de manière à permettre l'écoulement de la cire liquide sur sa périphérie, et entre cette dernière et la face interne de la tête 11. Le rouleau applicateur 15 est constitué d'un noyau 16 réalisé en un matériau bon conducteur de chaleur, et par exemple en aluminium. Le noyau 16 est avantageusement cylindrique et de section circulaire et est pourvu sur chacune de ses deux extrémités opposées constituant les faces latérales du rouleau 15, d'un tourillon 17. Ces derniers sont réalisés, par exemple par décolletage dans la masse même du noyau 16, les tourillons 17 s'étendant selon l'axe y-y', et formant les axes de rotation du rouleau 15.The hot-melt product applicator according to the invention also includes an applicator roller 15 with a longitudinal axis of revolution y-y ' arranged in the outlet opening of the tank 2 so as to allow the flow of liquid wax on its periphery, and between the latter and the face internal of the head 11. The applicator roller 15 consists of a core 16 produced in a material which is a good heat conductor, for example aluminum. The core 16 is advantageously cylindrical and of circular section and is provided on each of its two opposite ends constituting the lateral faces of the roller 15, of a pin 17. These are produced, for example by free-cutting in the mass of the core 16, the pins 17 extending along the axis y-y ', and forming the axes of rotation of the roller 15.

Le noyau 16 est entouré, de préférence sur toute sa surface périphérique par un revêtement en matériau plastique, avantageusement surmoulé, formant la couche d'application 18 de la cire.The core 16 is surrounded, preferably over its entire surface peripheral by a coating of plastic material, advantageously overmolded, forming the application layer 18 of the wax.

Le rouleau applicateur 15 est monté sur la tête 11 et supporté sur cette dernière par l'intermédiaire des tourillons 17 qui forment les moyens de liaison avec le corps de l'applicateur. De manière avantageuse le rouleau 15 est monté de manière amovible sur la tête 11 par l'intermédiaire de fentes 20 ouvertes à leur extrémité supérieure et ménagées dans l'épaisseur de chacune des faces opposées de la tête 11. Les fentes 20 sont ouvertes à leur extrémité supérieure et permettent ainsi le passage des tourillons 17 qui viennent alors reposer dans le fond de chacune des fentes 20. (Figure 2a).The applicator roller 15 is mounted on the head 11 and supported on the latter via the pins 17 which form the means of connection with the body of the applicator. Advantageously, the roller 15 is removably mounted on the head 11 via slots 20 open at their upper end and arranged in the thickness of each opposite faces of the head 11. The slots 20 are open at their ends upper and thus allow the passage of the pins 17 which then come rest in the bottom of each of the slots 20. (Figure 2a).

Le maintien en position des tourillons 17 au fond de chaque fente 20 est assuré par l'intermédiaire d'un moyen de blocage susceptible de s'effacer pour permettre l'amovibilité et l'extraction du rouleau 15. A cet effet les moyens de blocage sont avantageusement constitués par une agrafe 21, de forme générale en U, montée de manière fixe le long et contre chaque fente 20, la partie ouverte du U étant en correspondance avec l'ouverture de chaque fente 20. Chaque agrafe 21 comporte deux bras latéraux s'étendant sensiblement selon la même direction que les fentes 20, lesdits bras formant entre eux un rétrécissement 22 dans la partie supérieure de l'agrafe 21, de manière à bloquer chaque tourillon 17 dans le fond de chaque fente 20. L'agrafe 21 est réalisée dans un matériau métallique possédant une élasticité suffisante pour permettre aux bras latéraux de se déformer élastiquement lors de l'insertion ou de l'extraction des tourillons 17 dans et hors des fentes 20, et à travers le rétrécissement 22.Maintaining the pins 17 at the bottom of each slot 20 is provided by means of a blocking means capable of being erased to allow the removability and the extraction of the roll 15. For this purpose the means of blocking are advantageously constituted by a clip 21, of general shape U-shaped, fixedly mounted along and against each slot 20, the open part of the U being in correspondence with the opening of each slot 20. Each clip 21 has two lateral arms extending substantially along the same direction that the slots 20, said arms forming between them a narrowing 22 in the upper part of the clip 21, so as to block each pin 17 in the bottom of each slot 20. The clip 21 is made of a material metal with sufficient elasticity to allow the side arms to elastically deform when inserting or removing pins 17 in and out of the slots 20, and through the narrowing 22.

L'applicateur conforme à l'invention comporte avantageusement un cache-tête 12 destiné à venir s'appliquer sur la tête 11 et à prolonger le boítier 1. Une coiffe de fermeture 13, amovible est rapportée sur toute la partie supérieure de l'applicateur.The applicator according to the invention advantageously comprises a head cover 12 intended to be applied to the head 11 and to extend the housing 1. A removable cover cap 13 is attached over the entire upper part of the applicator.

La mise en place ou l'extraction du rouleau applicateur 15 peut bien évidemment être obtenue par préhension directe du rouleau 15, mais cette opération est avantageusement réalisée à l'aide d'une pince d'extraction. The placement or extraction of the applicator roller 15 may well obviously be obtained by direct gripping of the roller 15, but this operation is advantageously carried out using an extraction pliers.

Les figures 3 et 4 montrent une variante de réalisation préférentielle de l'invention selon laquelle le rouleau applicateur 15 est monté déplaçable sur le boítier 1 et relativement à ce dernier entre une position de travail et d'application d'une pellicule de cire dans laquelle il s'étend dans l'orifice de sortie 11b du réservoir 2 et une position de dégagement dudit orifice pour permettre le remplissage du réservoir 2. Le rouleau applicateur 15 est solidaire d'un coulisseau 50 monté déplaçable par coulissement longitudinal selon l'axe x-x' sur le boítier 1 et de préférence sur la tête 11 formant la partie supérieure du boítier 1. Le coulisseau 50 comporte deux jambages 51 s'étendant sensiblement parallèlement, reliés rigidement en position d'opposition par une entretoise 52. Chaque jambage est pourvu à son extrémité supérieure de perçages 53 axialement alignés pour le support des tourillons 17 du rouleau applicateur 15. Le coulisseau 50 est destiné à être inséré dans le corps du boítier 1, les jambages 51 coulissant contre les faces internes de la tête 11 (Figure 4). Chaque jambage 51 comprend en partie centrale une languette de blocage 58 découpée dans l'épaisseur du jambage 51. Les languettes 58 se terminent à leur extrémité supérieure par un rebord 54 replié en direction de l'axe x-x', chaque rebord 54 étant destiné à venir engager, lorsque le coulisseau 50 est en position basse de travail, tel que monté à la figure 4, un pan incliné 55 ménagé à la partie inférieure de la tête 11 pour bloquer en position le coulisseau 50. Les languettes de blocage 58 possèdent une élasticité suffisante pour se déformer en direction de l'axe x-x' et permettre, par préhension du rouleau applicateur 15, l'effacement des rebords 54 hors des pans inclinés 55 et le coulissement selon la flèche F1 du coulisseau hors de l'orifice de sortie 11b jusqu'à sa position haute de dégagement. Avantageusement, le coulisseau 50 est pourvu, vers l'extrémité inférieure de chaque jambage 51, de butées externes 56 aptes à venir engager les pans inclinés 55 lorsque le coulisseau 50 est en position haute de dégagement pour s'opposer à son extraction totale. Un tel montage ne diminue pas la transmission de l'énergie thermique au noyau 16, car en position de travail, les tourillons 17 sont supportés par des colonnes 57 ménagées dans la tête 11.Figures 3 and 4 show a preferred embodiment of the invention according to which the applicator roller 15 is movably mounted on the housing 1 and relatively to the latter between a working position and application of a wax film in which it extends into the outlet orifice 11b of the reservoir 2 and a release position of said orifice to allow filling of the reservoir 2. The applicator roller 15 is integral with a slide 50 mounted movable by longitudinal sliding along the axis x-x 'on the housing 1 and preferably on the head 11 forming the upper part of the housing 1. The slide 50 comprises two legs 51 extending substantially parallel, connected rigidly in the opposing position by a spacer 52. Each leg is provided at its upper end with axially aligned holes 53 for the support of the pins 17 of the applicator roller 15. The slide 50 is intended to be inserted into the body of the housing 1, the legs 51 sliding against the faces internal parts of head 11 (Figure 4). Each leg 51 comprises in the central part a locking tab 58 cut in the thickness of the jamb 51. The tabs 58 terminate at their upper end with a flange 54 folded in direction of the axis x-x ', each flange 54 being intended to come to engage, when the slide 50 is in the low working position, as mounted in FIG. 4, a pan inclined 55 formed at the bottom of the head 11 to lock in position the slide 50. The locking tabs 58 have sufficient elasticity to deform in the direction of the axis x-x 'and allow, by gripping the roller applicator 15, the erasure of the edges 54 out of the inclined faces 55 and the sliding along arrow F1 of the slide out of the outlet orifice 11b to its high release position. Advantageously, the slide 50 is provided, towards the lower end of each leg 51, with external stops 56 able to engage the inclined faces 55 when the slide 50 is in position high clearance to oppose its total extraction. Such an arrangement does not not reduce the transmission of thermal energy to the core 16, because in position working, the pins 17 are supported by columns 57 formed in the head 11.

L'applicateur de produits thermofusibles conforme à l'invention fonctionne de la manière suivante.The applicator of hot-melt products according to the invention works as follows.

L'utilisatrice procède tout d'abord à l'extraction du rouleau applicateur 15 afin de dégager l'accès au réservoir 2 pour assurer son chargement en cire à épiler par l'ouverture supérieure 2b. Pour ce faire l'extraction peut avoir lieu manuellement ou à l'aide d'une pince. L'utilisatrice peut faire glisser les tourillons 17 dans les fentes 20 et extraire le rouleau applicateur 15 en développant une force supérieure à l'élasticité des bras latéraux de l'agrafe 21. Après avoir procédé au remplissage du réservoir 2 le rouleau applicateur 15 est remis en place à l'aide des mêmes opérations que celles décrites précédemment, en transmettant aux tourillons 17 la force nécessaire pour écarter au niveau du rétrécissement 22 les bras latéraux de l'agrafe 21.The user first extracts the roll applicator 15 in order to clear access to the reservoir 2 to ensure its loading in depilatory wax through the upper opening 2b. To do this extraction can take place manually or using pliers. The user can slide the pins 17 into the slots 20 and extract the applicator roller 15 by developing a force greater than the elasticity of the lateral arms of the clip 21. After filling from reservoir 2 the applicator roller 15 is replaced using the same operations than those described above, by transmitting to the trunnions 17 the force necessary to spread at the level of the narrowing 22 the lateral arms of the clip 21.

Après branchement de l'applicateur sur une source d'alimentation électrique la cire devient progressivement liquide et l'utilisatrice peut alors mettre en contact le rouleau applicateur 15 sur la surface à épiler en vue de permettre l'écoulement de la cire sur la couche d'application 18. A la fin de l'application l'utilisatrice peut à nouveau, à des fins de nettoyage par exemple, extraire le rouleau applicateur 15 à l'aide d'une pince selon les étapes décrites précédemment.After connecting the applicator to a power source electric the wax gradually becomes liquid and the user can then put in contact with the applicator roller 15 on the surface to be depilated in order to allow the flow of the wax onto the application layer 18. At the end of the application the user can again, for cleaning purposes for example, extract the applicator roller 15 using pliers according to the steps described previously.
