Definitions

  • the present invention relates to packaging systems and application of cosmetic product to be heated, as well as uses of such systems.
  • the invention relates to a system for packaging and applying a cosmetic product as defined in the appended claims.
  • the document GB 2448 039 describes an example of an applicator device comprising a heating device.
  • the document EP1827160A1 discloses an example of an applicator device in which the heating element is in the form of a resistive wire twisted or helically wound along its direction of extension inside the groove formed in the applicator head, around a support element of dielectric material.
  • These measures applicator has the disadvantage of requiring a significant energy to heat the resistive wire, because of its length, which involves using a high power source of energy to heat the wire to reach the desired temperature to make melt the loaded cosmetic product on the applicator head.
  • this energy source is integrated in the product packaging and application system, and more particularly to the applicator device, it is necessary to provide a housing of sufficient size to accommodate this energy source, which generates important constraints in particular in terms of size and design of the applicator device.
  • the use of a twisted resistive wire as heating element in the applicator head also has the disadvantage of requiring a relatively long heating time, of the order of 30 seconds for a head having, for example, a length of order of 15 to 20 mm, to reach a temperature sufficient to melt the loaded cosmetic product on the applicator head, which makes it tedious the use of an applicator device equipped with such an applicator head.
  • a twisted resistive wire having a large footprint its integration into the applicator head generates significant design and design constraints.
  • the applicator head described in this document EP1827160A1 is of great complexity and is largely inspired by the heating heads of "curlers", or curling devices, which are well known for curling eyelashes by the sole effect of heat, especially in Asia. These heads are not suitable for both the heating and the application of a cosmetic product on the eyelashes.
  • the twisted resistive element is generally placed in a central groove large width, which induces strong constraints, especially in terms of design of the applicator head.
  • This type of heating head has many other drawbacks because it only allows the product to be heated on one side of the applicator head and the liquid product once at a temperature is very poorly distributed and therefore very poorly distributed on the head. As a result, the product in liquid form is not completely applied and accumulates on and around the resistive element.
  • combing means typically teeth forming a brush, are inefficient because imperatively located on a given area of the head and without direct fluid communication with the central groove.
  • the present invention is intended to overcome these disadvantages.
  • the invention proposes a system for packaging and applying a cosmetic product comprising an applicator device of the aforementioned type wherein the heating element comprises a resistive wire having a main portion extending along the axis of extension of the main portion of the throat, over the entire length of said main portion of the throat.
  • the main portion of the resistive wire forming the heating element extends over the entire length of the main portion of the groove along its axis of extension.
  • the resistive wire forming the heating element has in its main portion a shape corresponding to the main portion of the groove.
  • the main portion of the resistive wire will have a curved shape, zigzag or corresponding straight line.
  • the rise in temperature of the heating element to reach a temperature sufficient to melt the cosmetic product loaded on the applicator head can be performed more quickly and may require less energy than with the applicator heads.
  • the resistive wire implemented on the applicator head according to the invention having in its main portion a shape corresponding to that of the main portion of the groove in which it is arranged, its length can be reduced compared to the twisted wire implemented in the applicator heads of the prior art, which allows a temperature rise faster and requiring less energy than in existing devices.
  • the temperature drop is faster than with a twisted resistive wire, which makes it possible to avoid heating the product contained in a tank, and having not yet been heated, when the applicator head is to be recharged into the product to be applied and is immersed in this product reservoir. This avoids unnecessarily subjecting the cosmetic product contained in this tank repeated cycles of heating / cooling likely to alter its physicochemical properties.
  • heating element makes it possible to have a great freedom of design of the applicator head, in particular in terms of shapes and dimensions, in particular in order to be able to have means of combing / product application as effective as the brushes of the applicator heads of the prior art devoid of heating element, in order to maintain an optimal gesture and comfort of use.
  • One of the major problems generally associated with cosmetic product applicators using a heated applicator head is that there is always a quantity of product on the applicator head on or off the applicator head. vicinity of the heating element after application. This residue of product is inevitably intended to be heated again but also to be brought into contact with the product that has never been heated when the applicator head is plunged into a reservoir to be recharged product. This phenomenon is not desirable and it should therefore be possible to limit it as much as possible. Indeed, the cosmetic product may lose its properties after multiple heating, the mixture of heated and unheated product can cause the formation of pack within the reservoir and / or on the applicator head, and finally the applicator head becomes dirty over time. There is therefore a need for a device for dosing the amount of product to be heated and to limit the accumulation on the applicator head after application and in particular at the level of the heating element.
