Definitions

  • the invention relates to an applicator device for a fusible product such as depilatory wax, of those comprising a casing which can be held with one hand and is open at the upper part, delimiting a cavity which, in the form of a receptacle, receives the insertion of a wax-storing container which is provided with dispensing means.
  • a fusible product such as depilatory wax
  • the technique of depilation by the application of a heat-fusible product consists of melting a certain amount of this product, which at room temperature is in a solid or pasty state, and of applying a layer of the product on the area which is to be depilated. After the hardening, i.e., after the cooling, the film of cold wax is removed with aid of any suitable means, the hair then being extracted from the skin because it is bonded with the wax.
  • Depilatory wax applicators are currently known which are provided with an exchangeable wax container and with heating means for raising the temperature of the stored wax, which is heated until reaching the temperature suitable for keeping it liquid enough to be able to be spread.
  • some of the known compact applicators such as the one described in ES2138309T3 , need an additional component, formed by a base connected to the mains and provided with converting means for providing the suitable voltage to the heating means.
  • the base has electric terminals suitable for being connected to other complementary electric terminals provided in the applicator when the latter is coupled to the base.
  • the heating means of the applicator are thus powered until the wax acquires the level of temperature suitable for its use; the applicator must then be separated from the base to use it.
  • this type of applicator provided with a base has drawbacks since it has electric terminals exposed both in the base and in the applicator which can easily become dirty in case molten wax is spilled and stop making good contact, requiring a periodic cleaning to be able to be effective.
  • the applicator device for fusible products of the invention comprises a casing which can be held with one hand and is open at the upper part, delimiting a cavity which, in the form of a receptacle, receives the insertion of a wax-storing container which is provided with dispensing means.
  • the device is essentially characterized in that the casing is provided with a plug for its direct connection to the slots of an electrical socket, the prongs of the plug being permanently connected by means of low resistivity electrical connection means, such as electric cables, to heating means, essentially powered at the voltage of the mains and arranged in the receptacle facing at least one of the faces of the wax-storing container.
  • low resistivity electrical connection means such as electric cables
  • the heating means comprise a PTC thermistor, i.e., a resistor which is variable according to the temperature thereof, and a dissipation plate in contact with the PTC thermistor which allows homogeneously distributing the heat generate by the latter.
  • the switching temperature of the PTC thermistor i.e., the equilibrium temperature of the PTC thermistor at which its resistivity prevents the sufficient passage of electric current to allow increasing the temperature
  • said temperature is 40°C, a suitable temperature for the wax to be liquid enough to be easily spread, without causing burns, on the user's skin.
  • the container is parallelepiped and the surface area of the dissipation plate in contact with the container is essentially equal to the surface area of one of the faces of said container.
  • the dissipation plate can be provided with conducting extensions surrounding the PTC thermistor to achieve conducting as much heat as possible towards the container in an effective manner.
  • the surface area of the dissipation plate is 1200 mm 2
  • the volume of the container is 25 ml
  • the maximum power dissipated by the PTC thermistor is 4 W, said ratios being those suitable to allow sufficiently heating the wax of the container.
  • the surface area of the dissipation plate is 2400 mm 2
  • the volume of the container is 50 ml
  • the maximum power dissipated by the PTC thermistor is 4 W, said ratios also being those suitable to allow sufficiently heating the wax of the container.
  • the mouth of the wax-storing container is cylindrical, the mentioned mouth having a diameter of 12 to 15 mm, which allows the hot wax in a liquid or semi-liquid state to be able to flow to the dispensing means and be applied by means of the roller on the user's skin.
  • the device furthermore comprises first and second heat insulation means, applied in the inner and outer part of the casing, respectively, and arranged facing the heating means to prevent the heat produced by the heating means from excessively heating the casing and the user's hand during the use thereof.
  • the device depicted in Figure 1 is especially intended for the application of depilatory wax.
  • Said device comprises a casing 2, formed by two halves 2a, 2b, couplable according to a longitudinal plane of the device, which houses therein heating means 9 comprising a PTC thermistor 9a and a metallic dissipation plate 9b aiding in uniformly distributing the heat produced by the heating means 9.
  • Said dissipation plate 9b is separated from the second half 2b of the casing 2, by means of first heat insulation means 10, to prevent an excessively high level of heat from being transmitted to the second half 2b of the casing 2 and, consequently, to prevent burns from occurring in the latter or in the user's hand when holding the device 1.
  • the device 1 also incorporates second heat insulation means 11 in the outer part of the second half 2b of the casing 2 which, in addition to offering a better grip for the user's hand, prevent the heat which may be transmitted through the second half 2b of the casing 2 from burning the user's hand or hindering the use of the device when the casing 2 is hot.
  • the second half 2b of the casing 2 advantageously has securing means 10a for fixing the first insulation means 10 on which the dissipation plate 9b is arranged in a snap-fit manner.
  • the first half 2a is provided with a series of suitably distributed housings (not shown) which act in functional correspondence with respective protrusions 13 located in the second half 2b, the protrusions 13 being snap-fit into the housings in the coupling position.
  • the second half 2b furthermore has bent tabs 14b suitable for being housed in projections 14a provided in the first half 2a of the casing 2, the device 1 being thus firmly coupled, as shown in Figures 2a and 2b .
  • the second half 2b of the casing 2 furthermore has ventilation grooves 12 for allowing the exchange of air between the inside and the outside of the device 1 thus preventing an overheating of the device 1.
  • a cavity 3 is formed inside the device 1, with an opening 3a at the upper part thereof, delimited by the dissipation plate 9b and the casing 2, which allow tightly fitting a wax container 4.
  • Said wax container 4 is provided at its upper part with a mouth 4a connected to dispensing means 5 comprising a roller 5a to allow the exit of the wax from the inside of the container 4 and the spreading of the wax on the user's skin when the latter is sufficiently hot.
  • the PTC thermistor 9a has electrical connection means 9c which in the depicted variant are formed by electric cables sheathed with protective plastic material and connected to the prongs 7 arranged in the plug 6. Said plug 6 is located in the rear part of the second half 2b of the casing 2 and is permanently fit into the slots of an electrical socket of those usually known, thus powering the PTC thermistor 9a at the voltage of the mains.
  • the PTC thermistor 9a has to be properly designed to correctly withstand the mains voltages of each region, a maximum operating voltage therefore being determined which, in the depicted variant, is 230V.
  • the morphology of the plug must also be adapted according to the electrical sockets available in each region, the depicted variant being suitable for Type C European sockets.
  • the plug 6 is integrated in the casing 2 and allows the direct connection of the device 1 to the mains.
  • the PTC thermistor 9a increases its resistivity proportionally to its temperature, producing heat by the Joule effect until reaching an equilibrium temperature, after which its resistivity is high enough to not allow the passage of electric current and therefore produce heat, the PTC thermistor 9a being stabilized at said equilibrium temperature.
  • the equilibrium temperature of the PTC thermistor 9a it is necessary for the equilibrium temperature of the PTC thermistor 9a to be above the room temperature and to be suitable for melting the wax of the container 4, such that the wax can be easily spread by means of the dispensing means 5 on the user's skin, without causing burns.
  • a wax container 4, to which the dispensing means 5 have been previously coupled in its mouth 4a, must be introduced in the cavity 3, and the device 1 must be plugged into the mains such that the heating means 9 heat the wax until the desired level.
  • the heating means 9 heat the wax until the desired level.
  • the device 1 is furthermore reusable, because when the wax of the container 4 is used up, since the latter is detachable, the user can remove the empty container 4 and replace it with another full one, being able to reuse the device 1 for successive wax applications.
  • the device 1 since all the electrical connections are insulated from the user during the wax heating process, the device 1 meets the safety requirements to be directly powered at the voltage of the mains, without requiring a transformer for reducing said voltage, a compact and cost-effective applicator device 1 for wax therefore being achieved.
