Description
La présente invention concerne un dispositif permettant une application efficace et simple d'un produit, qui, à la température ambiante, se présente sous une forme solide et qui doit être réchauffé avant son utilisation pour être amené sous une forme pâteuse à la limite de l'état liquide. La présente invention se réfère plus particulièrement à l'application sur la peau de cires à épiler déposées sous forme de couches minces.The present invention relates to a device allowing an effective and simple application of a product, which, at room temperature, is in a solid form and which must be reheated before use to be brought in a pasty form to the limit of l liquid state. The present invention relates more particularly to the application to the skin of depilatory waxes deposited in the form of thin layers.
Le titulaire de la présente demande a récemment introduit sur le marché une nouvelle composition épilatoire qui est décrite en particulier dans sa demande de brevet français publiée sous le n° 2 617 708. Cette nouvelle composition épilatoire présente l'avantage de pouvoir être appliquée sur la peau en couches fines et régulières sans qu'il soit nécessaire d'utiliser les bandes d'application, notamment les bandes de "cellophane" qui étaient exigées par les compositions épilatoires selon la génération antérieure. Etant donné que le dépôt de la nouvelle composition épilatoire s'effectue en couches minces, il est nécessaire que la cire à épiler soit maintenue à la température pour laquelle elle présente une consistance pâteuse à la limite de l'état liquide, ce qui nécessite un chauffage de cette cire lors de l'application.The holder of this application recently introduced a new depilatory composition onto the market which is described in particular in his French patent application published under No. 2,617,708. This new depilatory composition has the advantage of being able to be applied to the skin in thin and regular layers without the need to use application bands, in particular the "cellophane" bands which were required by depilatory compositions according to the previous generation. Since the depilation of the new depilatory composition is carried out in thin layers, it is necessary that the depilatory wax is maintained at the temperature for which it has a pasty consistency at the limit of the liquid state, which requires a heating of this wax during application.
La présente invention se propose en conséquence d'apporter un dispositif permettant de réaliser le chauffage d'une telle cire à épiler.The present invention therefore proposes to provide a device for heating such a depilatory wax.
Il existe dans l'état antérieur de la technique divers dispositifs permettant de réchauffer les systèmes applicateurs de cire à épiler. De tels systèmes applicateurs se présentent généralement sous la forme d'un réceptacle en matériau, bon conducteur thermique dans lequel est logé le produit à réchauffer, notamment une cire à épiler, qui se présente sous la forme d'un bloc rechargeable, ce réceptacle étant muni à sa partie supérieure d'une tête d'application à rouleau égalisateur permettant de déposer la cire en couches minces sur la peau. Pour réchauffer cette cire avant son application, le système applicateur est placé dans un boîtier qui est muni de moyens de chauffage constitués généralement de résistances électriques raccordées au secteur de manière classique. Un exemple d'un tel système est décrit dans GB-A-2 113 994. Un tel système présente l'inconvénient de ne réchauffer la cire qu'avant son application, cette dernière, lors de l'application, reprenant rapidement son état solide, ce qui limite les périodes durant lesquelles il est possible d'appliquer la cire entre les stades de réchauffage dans ledit boîtier.There are various devices in the prior art for heating depilatory wax applicator systems. Such applicator systems are generally in the form of a receptacle made of a material, a good thermal conductor in which is housed the product to be heated, in particular a depilatory wax, which is in the form of a refillable block, this receptacle being fitted at its upper part with an application head with a leveling roller allowing the wax to be deposited in thin layers on the skin. To heat this wax before its application, the applicator system is placed in a box which is provided with heating means generally consisting of electrical resistances connected to the mains in a conventional manner. An example of such a system is described in GB-A-2 113 994. Such a system has the disadvantage of only heating the wax before its application, the latter, during application, quickly resuming its solid state , which limits the periods during which it is possible to apply the wax between the stages of reheating in said housing.
La présente invention se propose de perfectionner un tel système de chauffage et d'application de manière à augmenter dans des proportions considérables le temps durant lequel il est possible d'appliquer la cire en couches minces sur la peau.The present invention proposes to improve such a heating and application system so as to considerably increase the time during which it is possible to apply the wax in thin layers on the skin.
Cette invention a donc pour objet un dispositif de chauffage électrique et d'application de produits contenus dans des réceptacles, notamment de cire à épiler, comprenant un dispositif applicateur et un boîtier, le dispositif applicateur comportant un réceptacle en matériau thermiquement conducteur dans lequel est logé le produit à réchauffer, notamment une cire à épiler, se présentant sous la forme d'un bloc rechargeable, ce réceptacle étant pourvu à sa partie supérieure d'une tête d'application à rouleau égalisateur, ledit réceptacle étant conformé de manière à pouvoir se positionner, lorsque le dispositif applicateur n'est pas en cours d'utilisation, dans le boîtier muni de moyens de chauffage réalisés de façon à assurer un réchauffage à température de ramollissement du produit tel que le bloc de cire à épiler logé dans ledit réceptacle, et dans lequel les moyens de chauffage sont réalisés de façon à assurer également un réchauffage à cette même température de ramollissement de la tête d'application à rouleau égalisateur à l'aide d'une résistance électrique chauffante extérieure au dispositif applicateur, venant se positionner dans un logement prévu dans la la tête d'application, de préférence selon l'axe du rouleau en transmettant l'énergie calorifique à un système accumulateur de chaleur placé dans la tête d'application.This invention therefore relates to an electric heating device and application of products contained in receptacles, in particular depilatory wax, comprising an applicator device and a housing, the applicator device comprising a receptacle made of thermally conductive material in which is housed the product to be heated, in particular a depilatory wax, in the form of a refillable block, this receptacle being provided at its upper part with an application head with an equalizing roller, said receptacle being shaped so as to be able to be position, when the applicator device is not in use, in the housing provided with heating means produced so as to heat the product at softening temperature such as the block of depilatory wax housed in said receptacle, and in which the heating means are produced so as to also provide this heating e same softening temperature of the application head with leveling roller using an electric heating resistor external to the applicator device, positioned in a housing provided in the application head, preferably along the axis of roller by transmitting heat energy to a heat accumulator system placed in the application head.
Selon une caractéristique de la présente invention, le boîtier dans lequel est positionné ledit réceptacle est réalisé en deux parties :
- un corps recevant le réceptacle dans lequel est logé le produit à réchauffer tel que bloc de cire à épiler, et qui comporte au moins un élément chauffant tel que résistance électrique, disposé autour du logement recevant ledit réceptacle; et,
- un couvercle muni également de moyens de chauffage pour réchauffer la tête d'application à rouleau égalisateur.
- a body receiving the receptacle in which is housed the product to be heated, such as a block of depilatory wax, and which comprises at least one heating element such as electrical resistance, disposed around the housing receiving said receptacle; and,
- a cover also provided with heating means for heating the application head with leveling roller.
Selon un exemple de réalisation préféré de la présente invention, les moyens de chauffage sont électriques et alimentés à l'aide d'une pile rechargeable, ledit couvercle étant muni de lames de contact connectées à ladite pile rechargeable, sur lesquelles viennent s'appliquer des contacts prévus à cet effet aux extrémités de la résistance chauffante, assurant le chauffage du rouleau applicateur.According to a preferred embodiment of the present invention, the heating means are electric and supplied with the aid of a rechargeable battery, said cover being provided with contact blades connected to said rechargeable battery, on which are applied contacts provided for this purpose at the ends of the heating resistance, ensuring the heating of the applicator roller.
Selon une variante de réalisation de l'invention, conçue plus particulièrement pour éviter les différences de température importantes dans le coeur du bloc de cire par rapport aux surfaces extérieures de ce dernier, c'est-à-dire pour obtenir une uniformisation de la température dans toute la masse du bloc de cire, les moyens de chauffage sont réalisés et disposés de façon à assurer en outre et simultanément le réchauffage à la température de ramollissement des surfaces extérieures et de coeur du produit tel que le bloc de cire à épiler.According to an alternative embodiment of the invention, designed more particularly to avoid significant temperature differences in the core of the wax block relative to the outer surfaces of the latter, that is to say to obtain a uniform temperature throughout the mass of the wax block, the heating means are produced and arranged so as to additionally and simultaneously provide heating to the softening temperature of the exterior and core surfaces of the product such as the block of depilatory wax.
Selon un exemple de réalisation de cette variante, le réchauffage de la partie centrale ou coeur du bloc de cire contenu dans le boîtier jetable est réalisé à l'aide d'au moins une résistance électrique s'étendant tout le long du bloc et pénétrant dans la masse de ce dernier.According to an exemplary embodiment of this variant, the heating of the central part or heart of the block of wax contained in the disposable housing is carried out using at least one electrical resistance extending all along the block and penetrating into the mass of the latter.
Selon une caractéristique de cette variante, le bloc de cire rechargeable ainsi que le boîtier jetable dans lequel ce bloc est logé présentent au moins un évidement longitudinal dans l'une de leurs faces, ledit évidement recevant la résistance destinée à assurer le réchauffage de la partie centrale du bloc de cire.According to a characteristic of this variant, the refillable wax block and the disposable case in which this block is housed have at least one longitudinal recess in one of their faces, said recess receiving the resistance intended to ensure the heating of the part. center of the wax block.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent divers modes de réalisation donnés à titre d'exemples dépourvus de tout caractère limitatif. Sur les dessins :

On se réfère en premier lieu à la figure 1 qui représente, en une vue en perspective, un premier mode de réalisation préféré du dispositif selon l'invention.Referring firstly to Figure 1 which shows, in a perspective view, a first preferred embodiment of the device according to the invention.
Ainsi qu'on l'a expliqué ci-dessus, le problème devant être résolu par la présente invention est de permettre une application efficace d'une cire à épiler qui à une température ambiante présente une consistance ferme et qui doit être utilisée à une température pour laquelle elle présente une consistance pâteuse, à la limite de l'état liquide, afin de pouvoir être étalée en couche mince sur la peau. Bien entendu, cet exemple d'application n'est pas limitatif, le dispositif objet de la présente invention pouvant être utilisé dans d'autres domaines techniques dans lesquels il est nécessaire d'appliquer sous forme de couches minces des produits qui, à température ambiante, se présentent sous forme solide.As explained above, the problem to be solved by the present invention is to allow effective application of a depilatory wax which at room temperature has a firm consistency and which should be used at a temperature for which it has a pasty consistency, at the limit of the liquid state, so that it can be spread in a thin layer on the skin. Of course, this example of application is not limiting, the device which is the subject of the present invention can be used in other technical fields in which it is necessary to apply, in the form of thin layers, products which, at ambient temperature , are in solid form.
Les cires à épiler actuellement utilisées sont conditionnées sous la forme de blocs rechargeables qui sont positionnés dans un logement prévu à cet effet dans un dispositif applicateur dont la partie supérieure présente un rouleau égalisateur qui dépose la cire à épiler sous forme de couches minces dont l'épaisseur est déterminée par une fente qui est prévue entre la tête d'application et le rouleau égalisateur.The depilatory waxes currently used are packaged in the form of refillable blocks which are positioned in a housing provided for this purpose in an applicator device, the upper part of which has an equalizing roller which deposits the depilatory wax in the form of thin layers, the thickness is determined by a slit which is provided between the application head and the leveling roller.
Sur la figure 1 des dessins annexés, le dispositif applicateur a été désigné dans son ensemble par la référence 10 et le bloc de cire à épiler logé dans ce dispositif applicateur a été représenté en 12. Sur cette même figure, on a représenté la tête 14 d'application pourvu de son rouleau égalisateur 16, la fente distribuant la couche de cire à épiler, en collaboration avec le rouleau 16 ayant été désigné par la référence 18. Un tel dispositif applicateur fait partie de l'état de la technique et, par conséquent, il ne sera pas décrit en détail.In FIG. 1 of the appended drawings, the applicator device has been designated as a whole by the
Le dispositif de réchauffage du bloc de cire à épiler 12 contenu dans le dispositif applicateur est constitué selon l'invention de deux moyens de chauffage : l'un permettant de réchauffer le bloc 12, et l'autre assurant le réchauffage de la tête d'application 14.The device for heating the block of
Dans cet exemple de réalisation qui n'a aucun caractère limitatif, le réchauffage du bloc de cire 12 est assuré par l'intermédiaire d'une résistance électrique 24 entourant le logement recevant le dispositif applicateur 10. Cette résistance peut être chauffée directement par l'énergie électrique du secteur ou bien elle peut être reliée à une pile rechargeable 32 par l'intermédiaire de conducteurs 26, 28 et de broches de connexion 30, 30′. Cette pile rechargeable peut être reliée au secteur de façon connue par l'intermédiaire d'un cordon de raccordement 34.In this exemplary embodiment which has no limiting character, the heating of the
Le réchauffage de la tête d'application 14 s'effectue à l'aide d'une résistance chauffante 36 qui est positionnée selon l'axe du rouleau égalisateur 16. A chacune de ses extrémités, cette résistance chauffante comporte des contacts 38, 38′ qui viennent appuyer contre des lames 40, 40′ logées dans le boîtier recevant le dispositif applicateur. A cet effet, ce boîtier comporte deux parties séparables : d'une part un corps 20 dans lequel est positionné le logement qui reçoit le dispositif applicateur 10 durant son réchauffage, et d'autre part un couvercle amovible 22 dans lequel sont positionnées les lames 40, 40′ décrites ci-dessus, et qui vient recouvrir la tête d'application 14 lors du réchauffage du dispositif applicateur. Comme on peut le voir sur le dessin, les lames 40, 40′ sont reliées aux conducteurs 26, 28, ce qui permet d'assurer un chauffage simultané de la résistance 24 et de la résistance 36.The
Selon un mode de réalisation préféré, la résistance chauffante 36 est extérieure à la tête d'application 14. Elle peut faire partie du corps 20 ou du couvercle amovible 22 et elle vient se positionner dans un logement prévu à cet effet dans le dispositif applicateur 10, de préférence selon l'axe du rouleau égalisateur 16 de ce dernier. Le dispositif 10 est alors muni d'un système accumulateur de chaleur auquel est transmis l'énergie calorifique provenant de la résistance 36. Lors de l'utilisation du dispositif applicateur, la résistance 36 reste en place sur le couvercle 22 ou sur le corps 20 et la chaleur accumulée par le système accumulateur assure le réchauffage du rouleau égalisateur 16.According to a preferred embodiment, the
Grâce à ce mode de réalisation, le rouleau égalisateur 16 est maintenu à une température suffisante pour que la cire reste à l'état pâteaux, durant une longue période d'utilisation, sans qu'il soit nécessaire de remettre périodiquement le dispositif applicateur 10 dans le boîtier 20, pour en réaliser le réchauffage, ce qui était obligatoire avec les systèmes de chauffage selon la technique antérieure.Thanks to this embodiment, the
Selon une variante de la présente invention, la résistance électrique 36 qui assure le réchauffage du rouleau égalisateur 16, peut être du type à accumulation thermique et, dans ce but, elle est entourée par un matériau réfractaire.According to a variant of the present invention, the
Pour permettre une application en couches minces, particulièrement efficace de la cire à épiler selon ce dispositif, il est préférable que la fente 18 ménagée dans la tête d'application 14 entre le rouleau égalisateur 16 et cette tête, présente une largeur comprise entre 0,10 et 1,5 mm.To allow a particularly effective application in thin layers of depilatory wax according to this device, it is preferable that the
On comprend de la lecture de la description qui précède que le dispositif selon la présente invention permet d'utiliser avec une grande efficacité les nouvelles compositions épilatoires appliquées en couches minces mentionnées ci-dessus, étant donné qu'un tel dispositif assure un maintien à température convenable de ces compositions durant de longues périodes d'application.It will be understood from reading the above description that the device according to the present invention makes it possible to use with great efficiency the new depilatory compositions applied in thin layers mentioned above, since such a device maintains the temperature suitable for these compositions for long periods of application.
On remarquera que le dispositif selon l'invention qui vient d'être décrit permet de réchauffer un bloc de cire à épiler placé dans son réceptacle, ce réchauffage étant facilité par le fait que la cire comporte des composants qui présentent une très faible conductibilité thermique. Par contre, on est confronté aux problèmes résultant de la différence de températures dans le coeur du bloc de cire par rapport aux surfaces extérieures de ce dernier.It will be noted that the device according to the invention which has just been described makes it possible to heat a block of depilatory wax placed in its receptacle, this reheating being facilitated by the fact that the wax comprises components which have a very low thermal conductivity. On the other hand, we are confronted with the problems resulting from the temperature difference in the core of the wax block compared to the outer surfaces of the latter.
Pour cette raison, l'invention prévoit une variante de réalisation dans laquelle on obtient une uniformisation de température dans toute la masse du bloc de cire. Selon cette variante illustrée aux figures 2 à 4, on prévoit d'autres moyens de réchauffage destinés à porter à la température convenable le coeur ou partie centrale du bloc de cire (12), cette température étant celle pour laquelle ce bloc présente une consistance pâteuse à la limite de l'état liquide, de façon que la cire alimente la tête (14), dont le rouleau applicateur (16) assure l'étalement de cette cire en couches minces sur la peau.For this reason, the invention provides an alternative embodiment in which a uniform temperature is obtained throughout the mass of the wax block. According to this variant illustrated in Figures 2 to 4, other heating means are provided intended to bring the core or central part of the wax block (12) to the suitable temperature, this temperature being that for which this block has a pasty consistency. at the limit of the liquid state, so that the wax feeds the head (14), the applicator roller (16) of which spreads this wax in thin layers on the skin.
Dans l''exemple de réalisation de cette variante illustrée par les figures 2 à 4, le moyen de réchauffage du coeur de bloc de cire (12) est réalisé sous la forme d'au moins une résistance (44) alimentée soit directement par le secteur, soit par l'intermédiaire de la pile jetable ou rechargeable (30), cette résistance (44) étant raccordée à la pile par l'intermédiaire des conducteurs (48, 26) d'une part, et (46, 28) d'autre part, connectés aux broches (30, 30′) de la pile (32). De préférence la résistance (44) présente la forme d'une tige dont la longueur est voisine de celle du bloc (12) et qui vient se loger dans un évidement allongé de forme correspondante prévu dans le boîtier (42) dans lequel est logé le bloc de cire (12). Par conséquent ce bloc de cire (12) présente également un évidement longitudinal de façon à s'adapter à la forme correspondante du boîtier (42) du dispositif applicateur.In the exemplary embodiment of this variant illustrated by FIGS. 2 to 4, the means for reheating the wax block core (12) is produced in the form of at least one resistor (44) supplied either directly by the sector, either via the disposable or rechargeable battery (30), this resistor (44) being connected to the battery via the conductors (48, 26) on the one hand, and (46, 28) d on the other hand, connected to the pins (30, 30 ′) of the battery (32). Preferably the resistor (44) has the shape of a rod whose length is close to that of the block (12) and which is housed in an elongated recess of corresponding shape provided in the housing (42) in which is housed the wax block (12). Consequently, this block of wax (12) also has a longitudinal recess so as to adapt to the corresponding shape of the housing (42) of the applicator device.
Comme on le voit sur la figure 2 la résistance chauffante (44) ainsi que ses conducteurs d'alimentation sont logés dans le corps (20) du boîtier dans lequel est positionné le logement qui reçoit le dispositif applicateur (10) durant son réchauffage, comme décrit ci-dessus en référence à la figure 1.As seen in Figure 2 the heating resistor (44) and its supply conductors are housed in the body (20) of the housing in which is positioned the housing which receives the applicator device (10) during heating, as described above with reference to Figure 1.
On peut bien entendu sans sortir du cadre de la présente invention prévoir plus d'une résistance telle que (44), ces résistances présentant de préférence des axes parallèles à l'axe vertical du dispositif applicateur et venant se loger dans des évidements correspondants qui sont prévus sur les différentes faces de ce dernier. Il est possible d'assurer une répartition du chauffage et donc d'obtenir une température homogène dans toute la masse du bloc de cire (12).It is of course without departing from the scope of the present invention to provide more than one resistor such as (44), these resistors preferably having axes parallel to the vertical axis of the applicator device and coming to be housed in corresponding recesses which are provided on the different faces of the latter. It is possible to ensure a distribution of the heating and therefore to obtain a uniform temperature throughout the mass of the wax block (12).
La figure 3 montre clairement la façon selon laquelle la résistance (44) est positionnée à l'intérieur du logement longitudinal prévu sur l'une des faces extérieures du boîtier (42) recevant le bloc de cire (12).Figure 3 clearly shows how the resistor (44) is positioned inside the longitudinal housing provided on one of the outer faces of the housing (42) receiving the wax block (12).
La figure 4 illustre une variante dans laquelle ce bloc de cire (12′) présente une section droite ayant sensiblement la forme d'une cardioïde, la résistance chauffante (44′) présentant sensiblement une forme de section droite triangulaire et venant se loger dans la partie de cette cardioïde adjacente au point de rebroussement de cette dernière, comme on peut le voir sur cette figure.FIG. 4 illustrates a variant in which this block of wax (12 ′) has a cross section having substantially the shape of a cardioid, the heating resistor (44 ′) having substantially a shape of triangular cross section and coming to be housed in the part of this cardioid adjacent to the cusp of the latter, as can be seen in this figure.
Bien entendu, on peut envisager diverses variantes en ce qui concerne les formes tant du bloc de cire rechargeable et du boîtier jetable le recevant que de la ou des résistances telles que (44 ou 44′) destinées à assurer le réchauffage de la partie centrale ou du coeur de ce bloc de cire.Of course, it is possible to envisage various variants as regards the shapes both of the rechargeable wax block and of the disposable casing receiving it as of the resistance or resistors such as (44 or 44 ′) intended to ensure the heating of the central part or from the heart of this block of wax.
Il résulte de la lecture de la description qui précède en regard des figures 2 à 4 que grâce à cette variante, on assure un réchauffage homogène de la totalité de la masse du bloc de cire, ce qui facilite considérablement l'utilisation du dispositif applicateur étant donné que la tête à rouleau d'application de ce dernier, qui est également pourvue de moyens de chauffage comme décrit ci-dessus, est alimentée à l'aide d'une cire à l'état pâteux presque liquide présentant une consistance homogène ce qui permet de réaliser une application efficace des couches minces de cires à épiler.It follows from reading the above description with reference to Figures 2 to 4 that thanks to this variant, it ensures a uniform heating of the entire mass of the wax block, which considerably facilitates the use of the applicator device being given that the roller head for applying the latter, which is also provided with heating means as described above, is supplied with a wax in an almost liquid pasty state having a homogeneous consistency which allows an efficient application of thin layers of depilatory waxes.
Il demeure bien entendu que la présente invention n'est pas limitée aux divers exemples de réalisation décrits et représentés ici, mais qu'elle en englobe toutes les variantes.It remains to be understood that the present invention is not limited to the various embodiments described and shown here, but that it encompasses all variants thereof.
