  • the material which constitutes it, the total bearing surface (sum of the bearing surfaces) between said element made of elastomeric material and the inner surface of the shell 18, and the sum of the forces exerted due to the compression of said element made of elastomeric material are determining parameters when determining the configuration of the element made of elastomeric material.
  • the force necessary for the extraction of the refill be at least twice the weight of the full refill, for example of the order two and a half times the weight of the full refill.
  • the pads 9 present, in the example of the figure 6 , a convex or bevelled shape depending on the so-called vertical direction which corresponds, moreover, to the direction of introduction (and extraction) of the refill, which allows a progressive compression of the pads during the insertion of the refill 1 in the shell 13.
  • the position of the pads 9, in the upper part of the tank 2, typically under the rim 5, allows the refill to be largely introduced into a shell 13 without effort, and to immobilize it in the shell by compressing the pads 9 to the end of the introduction.
  • the figure 7 represents, according to a view similar to that of the figure 6 , the interaction between a shell and the recharging of the figure 1 , in a pot formed with such a refill.
  • the embodiment of the figure 7 differs from that shown in figure 6 essentially by the configuration of the element made of elastomeric material 8 and of the pads 9 that it forms. Nevertheless, all the explanations given on the number of studs, the creation of a holding force by contact on the inner surface of the shell 18, etc., given with reference to the figure 6 apply to the embodiment of the figure 7 .
  • the pads 9 of the refill used in the pot of the figure 7 have a vertically elongated shape, that is to say parallel to the direction of introduction and extraction of the refill.
  • the thickness E formed by the stud 9 vis-à-vis the outer surface 7 of the side wall 3 of the tank 2 is greater than the clearance J between said outer surface 7 and the inner surface of the shell 18.
  • each pad 9 of the elastomeric material element 8 is compressed when the refill 1 is in place in the shell 13.
  • a chamfer 19 is formed on the stud 9.
  • the vertically elongated shape of the stud 9 Due to the vertically elongated shape of the stud 9, the latter is gradually introduced into the shell 13, which leads to a gradual increase in the force necessary for placing the refill 1 in the shell 13 (because the contact surface between the studs 9 of the tank 2 and the inner surface of the shell 18 increases progressively and proportionally with the length of the stud introduced) until contact between the rim 5 and the shoulder 17.
  • the present invention is obviously not limited to these embodiments.
  • the configuration of the elastomeric element, of the tank, and also of the shell can be very different from the configurations described above.
  • the presence of pads on the element made of elastomeric material is optional, since at least part of said element made of elastomeric material is in relief with respect to the external surface. of the tank.
  • Very varied shapes of elastomeric material elements are possible.
  • Several distinct elastomeric material elements may be present on the same refill.
  • the tank can have various shapes and constitutions, depending on the application considered.
  • the shell can have various shapes and constitutions.
  • the shell may be cubic, cylindrical, cubic or parallelepiped, spherical, and may or may not have a bottom, or be provided with an orifice in its bottom to facilitate the extraction of a refill.
  • the invention thus developed allows the removable maintenance of a cosmetic product refill in a shell in order to form a device for packaging an aesthetic cosmetic product which is refillable by exchanging the refill.
  • the maintenance is obtained by friction of the element made of elastomeric material on an internal surface of the shell.
  • the retaining means in particular the elastomeric element, can be completely invisible once the pot has been formed, and be hardly visible on the refill.
  • the element made of elastomeric material can also constitute an element of visual or aesthetic differentiation, or an element of haptic differentiation for the product.
  • the shell can have a shape that is simple to produce, since the inner surface of the shell intended to interact with the elastomeric material element of the refill for its maintenance does not require the formation of any particular mechanical device.
  • a pre-existing container for example a conventional glassware container, can thus be used without adaptation as the shell of the device for packaging cosmetic product.
