Definitions

  • the present invention relates to a method for making a composite item comprising at least one cast (i.e. poured) cosmetic product and at least one solid decorative element such as a stone, crystal, or gem.
  • the decorated cosmetic products known in the art can also be in the form of composite items in which a different decorative cosmetic product is associated with a base cosmetic product by means of mechanical or chemical bonds (such as gluing).
  • the Spanish patent application ES 2.027.585 in the name of AVON relates to a method for incorporating suitably shaped decorative cosmetic products within a base cosmetic product, such as cast in a mould and then solidified.
  • the method by AVON provides that the decorative product, though being of a different colour from the base cosmetic product, has the same composition of the latter and is previously cast, within a suitable removable mask, within the mould intended for the casting of the base cosmetic product.
  • the mask can be removed and the base cosmetic product can be cast within the mould, such that the decorative cosmetic product is incorporated within the base product.
  • the method by AVON assumes that the decorative cosmetic product has the same composition as the base cosmetic product and that this decorative cosmetic product can adhere, after it has solidified, to the inner walls of the mould for the base cosmetic product.
  • the method by AVON when the decorative cosmetic product does not sufficiently adhere to the mould of the base cosmetic product, obviously, the achievement of the decoration in the finished product can be compromised.
  • the method by AVON teaches to make decorations that are always substantially flush with the outer surface of the base cosmetic product, without providing for these decorations to be made in relief relative to the latter.
  • the Applicant has finally suggested to couple, such as by means of gluing, solid decorative elements, such as for example objects of glass, crystal or stones, either semiprecious or precious, with a base cosmetic product, of the type preferably obtained by pressing cosmetic powders or by means of extrusion and solidification of an initial cosmetic slurry.
  • a base cosmetic product of the type preferably obtained by pressing cosmetic powders or by means of extrusion and solidification of an initial cosmetic slurry.
  • Another object of the present invention is to propose a method for making a composite item comprising a cast base cosmetic product and a solid decorative element that does not suffer from the drawback of the prior art, and thus allows a firm coupling of a solid decorative element to a cast cosmetic product, even when the materials of the decorative element and cosmetic product are essentially different from each other.
  • Another object of the present invention is to provide a method for making a composite item comprising a cast cosmetic product and a solid decorative element, which is simple to implement, allows the solid decorative element to possibly protrude from the cosmetic product surface and ensures a firm coupling of this cosmetic product and decorative element, even when the latter is an object made of glass, crystal, stone, plastics or any other non-cosmetic material.
  • Yet another object of the present invention is to provide an equipment for implementing the method claimed herein to provide a composite item of the type described above. Summary of the invention
  • the method for making a composite item comprising at least one cast (i.e. poured) cosmetic product within a filling volume defined by the inner walls of a mould, and subsequently solidified, and at least one solid decorative element comprises the steps of: a. holding, due to suitable holding means, the solid decorative element at a portion of an inner wall of the mould for the cast cosmetic product such that the solid decorative element projects at least partially within said filling volume; b. then pouring the cast cosmetic product, substantially in the liquid state, within the mould until when this filling volume is reached; c. solidifying the cosmetic product; d. removing the solidified cosmetic product from the mould after said step of holding the solid decorative element has been completed.
  • solid decorative element any solid element, such as a stone or crystal or an object made of plastic or glass, substantially different from the cast cosmetic product with which it is associated, and which is in the solid state also and mainly during the casting of this cosmetic product.
  • This solid decorative element can thus be held to, such as mechanically or preferably by means of suction, a portion of the inner surface of mould for said cast cosmetic product, and it is not substantially subjected to deformations or breakage upon casting (pouring) of the latter.
  • the method provides that the solid decorative element is first bonded, and usually fixed, to a support made of plastics provided with a portion shaped to be anchored to the cosmetic product, when the latter, after it has solidified, completely wraps this anchorage portion. Due to the plastic support, that is for instance thermo-formed, it is obtained both a firmer anchorage between the solid decorative element and the finished cosmetic product, and, also as a function of the shape of this support, a possible simplification of the mechanical, magnetic or fluid hold of the solid decorative element at a wall of the mould for the cosmetic product, when the latter is being cast.
  • the method provides that the solid decorative element is held at an inner surface portion of the mould for the cosmetic product, due to fluid suction holding means, which provide that at least one through hole is formed within the inner surface of the mould.
  • fluid suction holding means which provide that at least one through hole is formed within the inner surface of the mould.

  • - Fig. 2 illustrates a composite item obtained by means of the method of the present invention
  • Fig. 3 show a side sectional view of a particular support for the solid decorative element that can be also used in the method in Fig. I a-If.
  • the method of the present invention for making a composite item comprising a cast cosmetic product 10 for make up, such as a lipstick, gloss, or a cosmetic composition for the eye contour area, etc., and a solid decorative element 1 provides the steps of: a) opening the mould 3a, 3b for the cast cosmetic product 10, or however gain access to the inner walls 5a, 5b of at least one half-mould 3a, in order to place said solid decorative element 1 in a predetermined portion of these inner walls 5a, 5b; b) holding (Fig.
  • this embodiment provides a first step (Fig. I a and I b) of placing and bonding a solid decorative element 1 , such as a crystal, glass or stone, either precious or semiprecious, or any other object desired to be incorporated within the finished item, to a respective support 2, preferably made of a thermo-formed plastic material.
  • a solid decorative element 1 such as a crystal, glass or stone, either precious or semiprecious, or any other object desired to be incorporated within the finished item
  • the bond between the decorative element 1 and the support 2, which bond preferably causes the two entities 1 and 2 to be integral to each other, can be obtained by gluing the latter, or as shown in Fig. 3, by means of a shape-coupling between a duly shaped rest portion 8 of the support 2 and a corresponding engaging portion of the decorative element 1.
  • this support 2 when the support 2 is used, as shown in Fig. 3, this support 2 comprises a rest portion 8, having a substantially cylindrical development with a circular base, provided with an inner seat having at least one elastically-deformable edge, which allows the snap-fitting and subsequent integral mechanical hold of a complementary outer surface portion of the decorative element 1 , such as to substantially mount the latter within the rest portion 8.
  • the rest portion 8 of the support 2 allows the decorative element 1 to partially project in a protruding manner from the upper surface of the support 2.
  • the support 2 also comprises an anchorage portion 7, which is intended to be incorporated within the cosmetic product 10 during the casting and subsequent solidification of the latter, and as in the embodiment in Fig. 3, it can consist of a sort of circular flange placed at the base of said rest portion 8.
  • the support 2 can be preferably made by thermoforming a plastic material, or alternatively, by means of any other suitable method and material (such as by forging a metallic material) which allows the bond between the decorative element 1 and the support 2 and between the latter and the cosmetic product 10.
  • the support 2 can provide any other shape of the anchorage portion 7, such as for example the provision of wings or bent portions or the like, which allows the support 2 to be firmly bonded to the cosmetic product 10, once the latter, after casting (i.e. pouring), has solidified about this anchoring portion 7.
  • the decorative element 1 can be shaped such as to have an anchorage portion relative to the cosmetic product 1 , such as projecting parts intended to be coated by the cosmetic product 1 after it has been cast and solidified.

  • the half-mould 3a which, with the complementary half- mould 3b, defines an inner volume 6 to be filled with the cosmetic product 10 in the substantially liquid state (also with high viscosity), is provided with holding means for the decorative element 1 comprising, in the particular embodiment shown herein, a through hole 4 connecting the inner volume 9 of the mould 3a, 3b, when assembled, to the external environment.
  • the through hole 4 can be connected to, at an outlet section 1 I b thereof, a suitable machine for generating a suction fluid flow (not shown), such a way that the decorative element 1 , by resting at the opposite inlet section 1 I a of the hole 4, allows this decorative element 1 to be held to the inner wall 5a of the half-mould 3a by suction.
  • the assembly of the mould 3a, 3b provided with mechanic and/or preferably fluid suction 4 holding means on at least part of an inner wall 5a thereof, constitutes the equipment for making a composite item of the type described herein, according to the method of the present invention.
  • This equipment preferably comprises a through hole 4 that is formed within a portion of an inner wall 5a of the mould 3a, 3b, which is fluidically fastened, at a section 1 1 b thereof, to a machine (not shown) for generating a suction fluid (air) flow and has a fluid flow inlet section 1 1 ⁇ that is shaped such as to hold said decorative element 1 substantially in a sealed manner in correspondence to at least one surface portion thereof.
  • the suction intended to hold the decorative element 1 in the desired position within the filling volume 6, does not interfere with the casting of the cosmetic product 10 within the volume 6.
  • mechanical means such as staples or clips can be alternatively used, this being however a more complicated use, which are shaped to hold the solid decorative element 1 , or the support 2 thereof, to the wall 5a of the half-mould 3a during the casting and solidification of the cosmetic product 10.
  • the decorative element 1 is substantially fixed to the surface 5a of the half-mould 3a at the part thereof which is desired to be viewed in the finished composite item and is also placed to project only partially within the filling volume 6 of the mould 3a, 3b.
  • the anchorage portion 7 of the support 2 for the decorative element 1 completely projects within the filling volume 6, such as to be completely surrounded by the cosmetic product 10 during the casting and subsequent solidification of the latter.
