Beschreibung
    FIELD OF THE INVENTION
  • [0001]
    The invention involves the field of cosmetic product applicators, typically, mascara.
  • DESCRIPTION OF RELATED ART
  • [0002]
    Mascara applicators are typically designed to operate in conjunction with the neck of a recipient mascara container.
  • [0003]
    These applicators consist of a) a cap, typically threaded, designed to operate in conjunction with the said neck of the recipient in order to seal the recipient by screwing in an axial direction to the said neck, b) a stem longitudinal in relation to the said axial direction, and c) a brush consisting of an axial support and a multiplicity of bristles or tufts of bristles, the said longitudinal stem being connected at its said upper extremity to the said cap and at its said lower extremity to the said support of the said brush.
  • [0004]
    As it is well known by persons skilled in the field, the said axial support is formed by a helical twist of a metallic wire in a “U” form, or of two metallic wires, in such a way as to form turns which attach the multiplicity of bristles, typically in their median part, as illustrated by way of example in the European patents No. 0 239 270, No. 0 329 606, No. 0 574 572, and in the French patent No. 2 607 373.
  • [0005]
    Nearly all the commercial mascara applicator brushes are made by the co-operation of a metallic wire and a multitude of bristles or tuft of bristles.
  • [0006]
    The problems encountered with traditional brushes are of many kinds:
      • on the one hand, the fabrication technique of these brushes imposes its own constraints and therefore results in brushes which are all similar. Even though a large variety of traditional brushes are accessible by varying, notably the nature and/or the quantity of bristles, this variety is constrained to a relatively narrow domain, such that mascara formulas must be adapted to the existing brushes. Now, there is always a demand for new mascara formulas for which the application is not necessarily optimum with traditional brushes.
      • on the other hand, there is a permanent necessity to supply applicators which are not only simple applicators, but which have new functions or which improve the functions of traditional applicators.
      • in addition, in the field of cosmetic products in particular, there is a permanent need to renew both the products offered to consumers as well as the methods of application.
  • SUMMARY OF THE INVENTION
  • [0010]
    According to the invention, the cosmetic product applicator, typically one for mascara, designed to operate in conjunction with the neck of a recipient designed to contain the said cosmetic product, consists of a) a cap, typically threaded, designed to operate in conjunction with the said neck for the purpose of sealing the said recipient by screwing on in a direction axial to the said applicator, b) a stem which is longitudinal to the said axial direction, and c) a brush consisting of an axial support and an application material connected to the said support by means of an attachment method, the said application material typically formed of a multitude of bristles or tufts of bristles, the said longitudinal stem being connected at its upper extremity to the said cap, and at its lower extremity to the axial support of the said brush, and is characterized in that the said support is a support made of plastic including part or all of the said means of attachment.
  • [0011]
    This plastic support is radically different from the state-of-the-art metallic wire coil. In fact, the plastic support according to the invention opens the door to a totally new field for mascara applicators, with the shaping techniques, as with the properties of plastic materials, being totally different from those involved by the use of a twisted metallic wire forming a multitude of turns.
  • [0012]
    As it will appear in the description and the figures, the invention offers a very high degree of fabrication flexibility, whether because of the variety of application materials that can be used, or by the form of the brush itself.
  • [0013]
    For all that, the invention simultaneously enables the high volume fabrication of brushes and applicators, and a “custom-designed” fabrication, or one adapted to short runs, in a way that the advantages of the invention are not negated by a redhibitory fabrication cost overrun.

      • an application material (6) distribution device (91)
      • a retaining clip (8) distribution and insertion device (92)
      • and a unit control (93) device.
  • DETAILED DESCRIPTION OF THE INVENTION
  • [0064]
    Based on the invention, the said axial support (5) may consist of one or more plastic parts.
  • [0065]
    Part or all of the said axial support (5) can form a solid piece (7) with the said longitudinal stem (3).
  • [0066]
    Generally, the said axial support consists of only a single moulded piece of thermoplastic material, and forms but a one-piece moulded part (7) with the longitudinal stem (3), as appears for example in FIGS. 1 a and 2 c.
  • [0067]
    The said axial support (5) can be cylindrical, oval, square or twisted in cross-section, and can have an extremity which is square, cylindrical, semi-cylindrical, solid or hollowed out so as to enable the retention of the product to be applied prior to removal.
  • [0068]
    On the external part or surface, the said axial support (5) may consist of a multitude of cavities or housings (50), each cavity or housing (50) providing a positive connection with at least one tuft of bristles typically in a “U” shape at its base or foot (610), the said multitude of cavities or housings (50) forming part of the said means of attachment.
  • [0069]
    Based on a method of the invention, each cavity or housing (50) can be comprised of a single cavity (51) positively connected to a tuft of bristles (61), as illustrated, for example in FIGS. 1 a to 3 g.
  • [0070]
    Based on another method of the invention, the said cavity or the said multitude of cavities (50) can be comprised of a groove, typically axial (52) or helical (52′) firmly attaching a multitude of tufts of bristles (61), as illustrated in FIGS. 4 a to 4 f.
  • [0071]
    Thus, it is possible to have a series or a row of housings (50), or more than one series or rows of housings, distributed around the axis or in the axial direction (10) of the brush, following a constant angle or not, or stacked up on a single face of the support. It is also possible to have a combination of these two configurations.
  • [0072]
    The number of housings (50) from one series to the other can be constant or variable, by possibly locally varying the length of the tuft of bristles.
  • [0073]
    In addition, the space between each (pair of) housings (50) can be constant or variable, so as to vary the type of brushing.
  • [0074]
    The exterior form of each housing can be level, as illustrated in FIGS. 1 a and 1 b, or conical as illustrated in FIGS. 2 a to 2 c, where the conical part can have a constant or variable height, and can possibly provide a comb function which could vary according to the section of the brush considered.
  • [0075]
    The exterior conical part could possibly be concave or convex, so as to guide the distribution of the cosmetic product withdrawn.
  • [0076]
    The internal diameter of each housing or each cone could be constant or variable from one housing to the next, so as to obtain tufts of bristles of different density or form on the same series or from one series to the other.
  • [0077]
    Based on a variant illustrated notably in FIGS. 1 a to 2 c, the said method of attachment (8) could consist of a multitude of retaining clips (80), each retaining clip being adapted to each cavity (50), so as to attach at least one tuft of bristles (61) to each cavity.
  • [0078]
    In this case, the said support (5) could consist of a multitude of single cavities (51), with each single cavity (51) consisting of a retaining clip (80) blocking a tuft of bristles (61). The multitude of retaining clips could be clipped or snapped in, inserted by force or possibly welded to the support.
  • [0079]
    These retaining clips (80) can be formed of rigid plastic or of elastomer, so as to introduce more flexibility into the brushing.
  • [0080]
    In this way, brushes (4) can be obtained with a length or larger dimension typically going up to 20 to 32 mm, and a width or smaller dimension typically going to 2 to 10 mm.
  • [0081]
