  • the core 46 extends from the assembly surface 54 and comprises successively: a connection portion 60; a support portion 62, a hinge portion 64 and an end portion 66.
  • connection portion 60 is adjacent to the assembly surface 54 and has a first maximum dimension 70, perpendicularly to the main axis 32.
  • the support portion 62 is adjacent to the connection portion 60 and has a second maximum dimension 72, perpendicularly to the main axis 32.

  • the hinge portion 64 extends from the front surface 74.
  • the hinge portion 64 is formed from at least one truncated stud 76 the widest end whereof is adjacent to the front surface 74.
  • the hinge portion 64 comprises two substantially identical truncated studs 76 disposed side by side on the front surface 74.
  • the end portion 66 forms an end of the core 46 opposite the assembly surface 54.
  • the end portion 66 is integral with the thinnest end or the or each truncated stud 76 of the hinge portion 64.
  • the end portion 66 preferably has a decorative or ornamental shape.
  • the first material 43 forming the main body 40 is preferably a polymer type plastic material. More preferentially, the first material 43 is chosen from thermoplastic elastomers such as Hytrel®, polybutylene terephthalate (PBT), and polyolefins such as polyethylene or polypropylene.

  • the fluid cosmetic product 28 is preferably a composition that is liquid, viscous or in gel form.
  • the fluid cosmetic product 28 is transparent or translucent to visible light.
  • the diffraction effect renders the tip 42 less visible, for a better visibility of the end portion 66 in the reservoir 12.
  • a method of using the conditioning and application device 10 will now be described.
  • a user unscrews the gripping member 14 from the neck 22 and extracts the applicator 16 from the reservoir 12.
  • the application head 80 traverses the squeezing device 24, the latter scrapes the cosmetic product 28 remaining on said head, except at the level of the application zone 82 which remains loaded with product.
  • the user then applies said application zone 82 on a keratinous surface such as the skin, in order to deposit the cosmetic product 28 thereon.
  • the truncated shape of the studs 76 of the hinge portion 64 enables the core 46 to be flexible so as to accompany an elastic deformation of said application head 80.
  • the presence of the shoulder 73 prevents the tip 42 from being detached from the main body 40 during the use of the applicator 16.
  • the tabs 78 overmolded in the notches 56 enhance the durability of the main body 40 / tip 42 assembly.
  • the applicator 16 as described above makes it possible to readily vary the appearance of said applicator 16 and the associated device 10. Indeed, the ornamental shape of the end portion 66 of the core 46 is readily adapted without fundamental modifications of the method of manufacturing the applicator 16.
  • the second mold of the method of manufacturing by bi-injection can be used for several different shapes of the end portion 66.
  • the shape of the hinge portion 64 is also adapted according to the shape of the end portion 66 and/or the flexibility sought for the core 46.
  • the number of truncated studs 76 of the hinge portion 64 is between one and five.
