II est connu de conditionner de la cire à épiler dans des boîtes en métal ou en une matière plastique bonne conductrice de la chaleur. Avant une opération d'épilation, la boîte de cire doit être placée dans la cuve d'un appareil de chauffage, appelé chauffe-cire, pour faire fondre le contenu de la boîte de cire, afin que la cire fondue puisse être ensuite appliquée et étalée sur la ou les parties du corps humain devant être épilées, soit au moyen d'une spatule, soit au moyen de bandes de tissu selon la nature de la cire. Les boîtes de cire à épiler contiennent généralement une quantité relativement importante de cire, usuellement environ 800 g, de sorte que le temps nécessaire pour que l'appareil de chauffage puisse faire fondre la totalité du contenu de la boîte est relativement long, usuellement plus de 10 minutes, voire plus de 20 minutes. Cela constitue manifestement une gêne pour les utilisateurs.The present invention relates to an assembly for waxing, of the type comprising on the one hand at least one box made of a material which is good conductor of heat, containing depilatory wax, and on the other hand, a heating device comprising at least one tank which is capable of receiving said box of wax, and electrical heating means which are in thermal relation with the wall of the tank to heat the latter and the box of wax which it contains. It is known to condition depilatory wax in metal boxes or in a plastic material that is good at conducting heat. Before a hair removal operation, the wax box should be placed in the tank of a heater, called a wax heater, to melt the contents of the wax box, so that the melted wax can then be applied and spread on the part or parts of the human body to be depilated, either by means of a spatula, or by means of strips of fabric depending on the nature of the wax. Boxes of depilatory wax generally contain a relatively large amount of wax, usually about 800 g, so that the time required for the heater to melt the entire contents of the box is relatively long, usually more than 10 minutes or more than 20 minutes. This clearly constitutes a nuisance for users.

D'autres caractéristiques et avantages de la présente invention ressortiront au cours de la description détaillée suivante de deux modes de réalisation de l'invention donnés à titre d'exemple en référence aux dessins annexés sur lesquels :Other characteristics and advantages of the present invention will emerge during the following detailed description of two embodiments of the invention given by way of example with reference to the appended drawings in which:
- la figure 1 est une vue en perspective éclatée d'un ensemble pour épilation à la cire selon un premier mode de réalisation de l'invention ; - la figure 2 est une vue en coupe verticale, à plus grande échelle, de l'ensemble de la figure 1 ;- Figure 1 is an exploded perspective view of an assembly for waxing according to a first embodiment of the invention; - Figure 2 is a vertical sectional view, on a larger scale, of the assembly of Figure 1;
- la figure 3 est une vue schématique, en coupe verticale, d'un ensemble selon un second mode de réalisation de l'invention. L'ensemble 1 pour épilation à la cire représenté dans les figures 1 et 2 comporte, de façon connue en soi, d'une part une boîte 2 contenant de la cire à épiler 3, et d'autre part un appareil de chauffage 4.- Figure 3 is a schematic view, in vertical section, of an assembly according to a second embodiment of the invention. The assembly 1 for waxing represented in FIGS. 1 and 2 comprises, in a manner known per se, on the one hand a box 2 containing depilatory wax 3, and on the other hand a heater 4.
La cire 3 peut être n'importe quelle cire à épiler connue, sous forme solide, par exemple en granulés, semi-solide ou pâteuse, nécessitant d'être chauffée pour l'amener dans un état suffisamment liquide pour qu'elle puisse être appliquée et étalée sous le forme d'une couche. La boîte 2 est usuellement munie d'un couvercle 5 qui est enlevé avant que la boîte 2 soit placée dans l'appareil de chauffage 4. L'appareil de chauffage 4 comprend, de façon connue en soi, une cuve 6 en un matériau bon conducteur de la chaleur, par exemple en aluminium, en alliage d'aluminium ou en acier inoxydable, qui est montée dans une cavité 7 formée dans la paroi supérieure 8a d'un coffret ou boîtier 8. Le coffret 8 contient un bloc chauffant 9 (figure 2) qui est en relation thermique avec la cuve 6 et qui peut être alimenté en courant électrique par l'intermédiaire d'un interrupteur 11, par exemple un interrupteur à bouton poussoir 12, et d'un câble d'alimentation 13 muni d'une fiche de connexion 14 pouvant être branchée dans une prise de courant (non-montrée). L'appareil de chauffage 4 comporte en outre, de façon connue, un témoin lumineux 15, qui est connecté dans le circuit d'alimentation du bloc chauffant 9 et qui est allumé lorsque ce dernier est sous tension. L'appareil de chauffage 4 peut en outre comporter, de façon connue, un régulateur de température (non-montré) constitué par exemple par un thermostat, tel qu'un bilame, ou par une résistance dépendant de la température, et agencé pour assurer une température de chauffage constante ou sensiblement constante. Le régulateur de température peut être également conçu de manière à permettre un ajustement de la température de chauffage à une valeur désirée selon la nature de la cire à épiler contenue dans la boîte 2.The wax 3 can be any known depilatory wax, in solid form, for example in granules, semi-solid or pasty, requiring to be heated to bring it into a sufficiently liquid state so that it can be applied. and spread as a layer. The box 2 is usually provided with a cover 5 which is removed before the box 2 is placed in the heater 4. The heater 4 comprises, in a manner known per se, a tank 6 made of a good material heat conductor, for example made of aluminum, aluminum alloy or stainless steel, which is mounted in a cavity 7 formed in the upper wall 8a of a box or box 8. The box 8 contains a heating block 9 ( Figure 2) which is in thermal relation with the tank 6 and which can be supplied with electric current by means of a switch 11, for example a push button switch 12, and a power cable 13 provided with 'a plug 14 which can be plugged into a power outlet (not shown). The heater 4 further comprises, in a known manner, an indicator light 15, which is connected in the supply circuit of the heating block 9 and which is lit when the latter is energized. The heating appliance 4 may further comprise, in a known manner, a temperature regulator (not shown) constituted for example by a thermostat, such as a bimetallic strip, or by a resistance depending on the temperature, and arranged to ensure a constant or substantially constant heating temperature. The temperature regulator can also be designed to allow adjustment of the heating temperature to a desired value according to the nature of the depilatory wax contained in the box 2.
Dans l'ensemble 1 selon l'invention, la boîte 2 comporte une ouverture 16 dans la région centrale de sa paroi de fond 17, et une partie 18 en forme de cloche, dont la paroi périphérique est raccordée d'un seul tenant au bord de l'ouverture 16 de la paroi de fond 17. La boîte 2 et sa partie en cloche 18 peuvent être par exemple réalisées par moulage d'une matière plastique bonne conductrice de la chaleur, par exemple du polypropylène. A titre de variante, la boîte 2 et sa partie en cloche 18 pourraient être réalisées en métal, par exemple en fer blanc ou autre métal approprié bon conducteur de la chaleur, selon des techniques semblables à celles utilisées pour la fabrication des boîtes de conserves.In assembly 1 according to the invention, the box 2 has an opening 16 in the central region of its bottom wall 17, and a part 18 in the shape of a bell, the peripheral wall of which is connected in one piece to the edge of the opening 16 of the bottom wall 17. The box 2 and its bell-shaped portion 18 can for example be produced by molding a plastic material that is good at conducting heat, for example polypropylene. Alternatively, the box 2 and its bell portion 18 could be made of metal, for example tin or other suitable metal good conductor of heat, according to techniques similar to those used for the manufacture of cans.
Dans l'appareil de chauffage 4 selon l'invention, il est prévu un élément chauffant 19 qui s'étend coaxialement à l'intérieur de la cuve 6 à partir de la paroi de fond 21 de celle-ci. Ainsi, lorsque la boîte 2 est placée dans la cuve 6, l'élément chauffant 19 est engagé dans la cavité de la partie en cloche 18 de ladite boîte. De préférence, la partie en cloche 18 a un diamètre et une hauteur qui sont sensiblement égaux respectivement au tiers du diamètre et au tiers de la hauteur de la boîte 2, comme montré dans la figure 2. En outre, l'élément chauffant 19 a de préférence une forme et des dimensions correspondant à celles de la cavité interne de la partie en cloche 18, de façon à assurer une bonne relation de transfert de chaleur entre l'élément chauffant 19 et la partie en cloche 18 lorsque la boîte 2 est placée dans la cuve 6. Dans le mode de réalisation représenté sur la figure 2, le bloc chauffant 9 est constitué par une plaque électrique chauffante 20, qui est en contact thermique avec la face inférieure de la paroi de fond 21 de la cuve 6. En son milieu, la plaque électrique chauffante 20 porte l'élément chauffant 19 qui passe à travers un trou 22 formé dans la région centrale de la paroi de fond 21, de manière à faire saillie à l'intérieur de la cuve 6. La plaque électrique chauffante 20 et l'élément chauffant 19 peuvent être réalisés sous le forme d'un seul bloc qui est fixé à la paroi de fond 21 de la cuve 6.In the heater 4 according to the invention, there is provided a heating element 19 which extends coaxially inside the tank 6 from the bottom wall 21 thereof. Thus, when the box 2 is placed in the tank 6, the heating element 19 is engaged in the cavity of the bell portion 18 of said box. Preferably, the bell portion 18 has a diameter and a height which are substantially equal to one third of the diameter and one third of the height of the box 2, respectively, as shown in Figure 2. In addition, the heating element 19 has preferably a shape and dimensions corresponding to those of the internal cavity of the bell portion 18, so as to ensure a good heat transfer relationship between the heating element 19 and the bell portion 18 when the box 2 is placed in the tank 6. In the embodiment shown in Figure 2, the heating block 9 is constituted by an electric heating plate 20, which is in thermal contact with the underside of the bottom wall 21 of the tank 6. In its middle, the electric heating plate 20 carries the element heater 19 which passes through a hole 22 formed in the central region of the bottom wall 21, so as to protrude inside the tank 6. The electric heating plate 20 and the heating element 19 can be produced under the shape of a single block which is fixed to the bottom wall 21 of the tank 6.
De préférence, la plaque électrique chauffante 20 a une superficie pratiquement égale à celle de la paroi de fond 21 de la cuve 6. La paroi périphérique 23 de la cuve 6 a de préférence un diamètre intérieur à peine plus grand que le diamètre extérieur de la boîte 2 et une hauteur telle qu'elle entoure la paroi périphérique de la boîte 2 sur la majeure partie de sa hauteur, de manière à obtenir un bon transfert thermique entre la paroi périphérique 23 de la cuve 6 et la paroi périphérique de la boîte 2 lorsque cette dernière est placée dans ladite cuve. Grâce à cela et grâce à la présence de l'élément chauffant 19, on est ainsi assuré, en service, que la masse de cire 3 contenue dans la boîte 2 sera chauffée uniformément dans tout son volume et que la cire sera amenée dans un état suffisamment liquéfié en un temps nettement plus court qu'avec les ensembles connus du même genre.Preferably, the electric heating plate 20 has an area practically equal to that of the bottom wall 21 of the tank 6. The peripheral wall 23 of the tank 6 preferably has an inside diameter barely larger than the outside diameter of the box 2 and a height such that it surrounds the peripheral wall of the box 2 over most of its height, so as to obtain good thermal transfer between the peripheral wall 23 of the tank 6 and the peripheral wall of the box 2 when the latter is placed in said tank. Thanks to this and thanks to the presence of the heating element 19, it is thus ensured, in service, that the mass of wax 3 contained in the box 2 will be heated uniformly throughout its volume and that the wax will be brought into a state sufficiently liquefied in a much shorter time than with known sets of the same kind.
Le coffret 8 de l'appareil de chauffage 4 peut être composé de deux pièces moulées 24 et 25, par exemple en matière plastique, qui, après installation du bloc chauffant 9, de l'interrupteur 11 et du témoin lumineux 15 dans la pièce moulée supérieure 24, sont fixées l'une à l'autre par exemple au moyen de plusieurs vis telle que la vis 26 montrée dans la figure 2. La figure 3 montre un second mode de réalisation de l'ensemble selon l'invention. Dans la figure.3, les éléments qui sont identiques ou qui jouent le même rôle que ceux du mode de réalisation des figures 1 et 2 sont désignés par les mêmes numéros de référence et ne seront donc pas décrits à nouveau en détail. Le mode de réalisation de la figure 3 diffère essentiellement du mode de réalisation des figures 1 et 2 en ce que le coffret ou boîtier 8 de l'appareil de chauffage 4, qui a ici la forme d'un parallélépipède rectangle, porte deux cuves 6 aptes à recevoir chacune une boîte de cire 2 identique ou semblable à celle des figures 1 et 2. A chaque cuve 6 est associé un bloc chauffant 9 identique ou semblable à celui de la figure 2. Les deux blocs chauffants 9 peuvent être alimentés en courant par un circuit d'alimentation comportant un unique interrupteur de marche/arrêt, mais on peut aussi prévoir deux interrupteurs de marche/arrêt, un pour chaque bloc chauffant 9, de telle façon que les deux blocs chauffants puissent être mis en service soit indépendamment l'un de l'autre par fermeture de l'interrupteur correspondant, soit en même temps par fermeture des deux interrupteurs.The box 8 of the heater 4 can be made up of two molded parts 24 and 25, for example of plastic, which, after installation of the heating block 9, the switch 11 and the indicator light 15 in the molded part upper 24, are fixed to each other for example by means of several screws such as the screw 26 shown in Figure 2. Figure 3 shows a second embodiment of the assembly according to the invention. In the figure . 3, the elements which are identical or which play the same role as those of the embodiment of FIGS. 1 and 2 are designated by the same reference numbers and therefore will not be not described again in detail. The embodiment of FIG. 3 essentially differs from the embodiment of FIGS. 1 and 2 in that the box or case 8 of the heating appliance 4, which here has the shape of a rectangular parallelepiped, carries two tanks 6 able to each receive a wax box 2 identical or similar to that of FIGS. 1 and 2. Each tank 6 is associated with a heating block 9 identical or similar to that of FIG. 2. The two heating blocks 9 can be supplied with current by a supply circuit comprising a single on / off switch, but two on / off switches can also be provided, one for each heating block 9, in such a way that the two heating blocks can be put into operation either independently 'from each other by closing the corresponding switch, or at the same time by closing the two switches.
Avec l'appareil de chauffage 4 de la figure 3, il est ainsi possible de chauffer simultanément deux boîtes de cire 2 contenant des cires de même nature ou des cires ayant des natures différentes selon les nécessités.With the heater 4 of Figure 3, it is thus possible to simultaneously heat two boxes of wax 2 containing waxes of the same kind or waxes having different natures as required.
Il va de soi que les modes de réalisation de l'invention qui ont été décrits ci-dessus ont été donnés à titre d'exemple purement indicatif et nullement limitatif, et que de nombreuses modifications peuvent être facilement apportées par l'homme de l'art sans pour autant sortir du cadre de l'invention. C'est ainsi notamment qu'au lieu de réaliser l'élément chauffant 19 et la plaque électrique chauffante 20 sous le forme d'un seul bloc chauffant 9, l'élément chauffant 19 et la plaque électrique chauffante 20 pourraient être constitués par des éléments séparés. Par exemple, l'élément chauffant 19 peut être constitué par une pièce en un matériau bon conducteur de la chaleur, qui peut faire partie intégrante de la cuve 6 et qui est chauffée en même temps que cette dernière par la plaque électrique chauffante 20 ou par une résistance électrique chauffante distincte de la plaque électrique chauffante.It goes without saying that the embodiments of the invention which have been described above have been given by way of purely indicative and in no way limitative example, and that numerous modifications can be easily made by those skilled in the art. art without departing from the scope of the invention. Thus in particular that instead of making the heating element 19 and the electric heating plate 20 in the form of a single heating block 9, the heating element 19 and the electric heating plate 20 could be constituted by elements separated. For example, the heating element 19 may consist of a part made of a material which is a good conductor of heat, which can be an integral part of the tank 6 and which is heated at the same time as the latter by the electric heating plate 20 or by an electric heating resistor separate from the electric heating plate.
Dans un autre mode de réalisation, au lieu d'être fixé à la face inférieure de la paroi de fond 21 de la cuve 6, le bloc chauffant 9 peut être porté par la pièce moulée inférieure 25 du coffret 8 de l'appareil de chauffage 4, de préférence par l'intermédiaire de cales de positionnement et d'espacement en matière isolante, de telle façon que la plaque électrique chauffante 20 du bloc chauffant 9 soit en contact thermique avec la face inférieure de la paroi de fond 21 de la cuve 6 lorsque les deux pièces moulées 24 et 25 du coffret 8 sont assemblées et fixées l'une à l'autre.In another embodiment, instead of being fixed to the lower face of the bottom wall 21 of the tank 6, the heating block 9 can be carried by the lower molded part 25 of the box 8 of the heating appliance 4, preferably by means of positioning and spacing shims made of insulating material, so that the electric heating plate 20 of the heating block 9 is in thermal contact with the underside of the bottom wall 21 of the tank 6 when the two molded parts 24 and 25 of the box 8 are assembled and fixed to one another.
Dans un autre mode de réalisation, au heu d'être en contact thermique avec la paroi de fond 21 de la cuve 6, les moyens électriques de chauffage 9 peuvent être conformés pour être disposés en contact thermique avec la paroi périphérique 23 de la cuve 6. In another embodiment, instead of being in thermal contact with the bottom wall 21 of the tank 6, the electrical heating means 9 can be configured to be arranged in thermal contact with the peripheral wall 23 of the tank 6 .
