Definitions

• the invention relates to cosmetic product applicators.
• An article of mascara, or "mascara”, conventionally includes a holster, a mascara tank and an appiicator.
• mascara applicators including brush-type applicators. These applicators form a brush which comprises bristles formed by fibers trapped in a twisted wire forming the core of the applicator.
• Such applicators give satisfactory results for the user. But the latter is always looking for new or better makeup effects.
• An object of the invention is therefore to improve the applicators of cosmetic product.
• a cosmetic product applicator comprising:
• a core forming a winding on at least one turn around a main axis of the applicator and along this axis so as to delimit a convex internal volume extending from one end of the winding to another end winding, and protuberances extending from the core,
• the applicator being arranged so that no part of the applicator, except possibly some of the protuberances, is in the convex internal volume.
• the convex internal volume serves as a reserve of cosmetic product.
• this volume is filled with product and a greater part of this reserve is always present after the applicator has passed through a wiper. In this way, it limits the number of reloads required during makeup and thus makes it easier for the user to make up.
• the or turns formed by the winding of the core around the main axis of the applicator contribute to particularly sought after makeup effects.
• they contribute to a good separation of the eyelashes as well as an elongating effect.
• they can help to push the eyelashes outwards and thus create a "crowbar" effect particularly sought after by the user.
• a convex volume is a volume in which, whenever we take any two points, the segment joining these two points is entirely contained in the volume.
• the protuberances are present in this space. In this case, these protuberances participate in the storage of the product being themselves loaded product. It is also possible to use a product having a reduced viscosity since the protuberances extending in the volume tend to limit the spontaneous flow of the product out of the volume and thus prevent the product from flowing.
• the winding of the core is helical.
• this winding could also be conical or frustoconical.
• the winding of the core has at least two sections having different helical pitches.
• the different helical pitches translate a more or less inclination, with respect to the main axis of the applicator, of the portion of core forming this pitch.
• an applicator which has sections with different helical pitches makes it possible to obtain different makeup effects along the applicator, which constitutes a makeup effect particularly sought after by the user.
• a cosmetic product applicator for the eyelashes the winding of the core of which has several different steps making it possible to make up the eyelashes by orienting them locally in different respective directions.
• the winding of the core has at least three sections with different helical pitches, preferably at least four sections, for example at least five sections.
• the core forms less than ten turns about the axis, preferably less than six turns, for example less than four turns.
• the protuberances form a single piece with the core, preferably all the protuberances forming a single piece with the core.
• the applicator is faster and / or less expensive to produce.
• At least some of the protuberances have lengths that differ from each other.
• the protuberances of the same applicator can have different functions.
• the longer protuberances are able to store and deposit product on the eyelashes, while the shortest protuberances are able to comb the eyelashes and to smooth the product present on these eyelashes.
• these characteristics make it possible to obtain a makeup result which is particularly satisfactory for the user.
• the core has an internal face oriented in the direction of the axis and an outer face oriented in the direction opposite to the axis, some of the protuberances which extend from the inner face having a longer length than some protuberances extending from the outer face, preferably all protuberances extending from the inner face having a greater length than any protuberances extending from the outer face.
• the longer protuberances that extend from the inner face are partially present in the convex internal volume and can play a role of storage of the cosmetic product, while the shorter protuberances which extend to from the outer face allow them, for example in the case of a product for the eyelashes, combing and separation of the eyelashes, and a smoothing of the cosmetic product which has been deposited for example by some of the longer protuberances.
• the extreme length reached by these protuberances over a good part of the width of the convex volume allows a large amount of mascara deposit.
• the protuberances extending from the inner face have a length of between 1 and 5 mm.
• the protuberances which elongate from the external face have a length of between 0.5 and 1 mm.
• the protuberances are elongated and recfilinear and extend in pans perpendicular to the axis.
• the protuberances have all other compatible forms for makeup, for example a curved shape, wavy or loop.
• the fact that protuberances extend in pans perpendicular to the axis of the applicator makes it possible to better order them and to limit the protuberances having an orientation that is too inclined relative to the axis, which could lead to makeup, especially combing, too irregular in relation to the result desired by the user.
• the applicator forms a cosmetic product applicator for the skin, nails, lips, eyelashes or eyebrows, and preferably forms a mascara applicator.
• a cosmetic article comprising an appiicator as described above.
• an electronic recording medium comprising in recorded form data for implementing the method as described above.
• FIG. 1 is a schematic longitudinal sectional view of a cosmetic article according to one embodiment of the invention.
• FIGS. 2 and 4 are side views in two different positions around the main axis of the applicator of the article of Figure 1;
• FIG. 3 is an end view of this applicator.
• FIG. 5 is a longitudinal sectional view of the applicator of Figures 2 to 4.
• the applicator 1 of mascara described in this embodiment is part of a cosmetic article 2 comprising a cap or a plug 3, to which the applicator 1 is rigidly connected, and a case 4 comprising a mascara reservoir 5 and a wiper 6 (see Figure 1) housed in the neck of the tank on which the cap can be fixed, for example screwed, removably to close the tank rarticle.
• the applicator then extends into the tank and bathes in the mascara.
• the applicator is carried by a rectiiigne rod 8 which connects it to the cap 3.
• the applicator has a generally elongated oval shape along its main axis 9.
• the rod 8 has a generally cylindrical rectiiigne general shape. The rod and the applicator are connected by one of their ends.
• the applicator may have other general forms, for example a frustoconical shape.
• the applicator 1 comprises a core 10 which forms a winding around the axis 9 of the applicator and along this axis (see FIGS. 2 and 4).
• the core forms three complete turns 11, or turns, around the axis 9 of the applicator.
• the core forms a winding comprising a larger or smaller number of turns 11.
• the winding of the core forms one, two, four, five, six or seven turns 11.
• the core is bonded at one of its ends to the rod 8, its other end being free.
• the applicator 1 comprises only a core 10.
• An applicator may be provided comprising a larger number of nuclei, for example two, three, four or five, extending at a distance from each other around of the axis and delimiting a common internal volume.
• the most proximal turn 11 and the most distal turn 11 have a substantially equal helical pitch p1 which is greater than the helical pitch p2 of the medial turn 11. It can of course be provided that all the turns of the applicator have the same pitch of helix p or that they all have a pitch of a helix p different from each other.
• the core 10 has a circular section in a yarn locally perpendicular to the axis of the core. It can be expected that this section has another shape, for example obarian, polygonal or oval.
• the core 10 is solid but it can be expected that it is hollow and / or that its walls form a maiiiage.
• the kernel extends completely away from the axis.
• the winding of the core 10 delimits a convex internal volume 12 extending from one end of the winding to another end of the winding.
• the internal volume 12 has a substantially cylindrical shape of axis 9, circular section in a plane perpendicular to this axis. This volume 12 is able to serve as a reserve of mascara. It can be provided that this convex internal volume 12 has another shape, for example a conical or frustoconical shape.
• the core has an inner face 13 oriented towards the axis and an outer face 14 facing away from the axis. Protuberances extend from these two faces of the core 10.
• the protuberances 15 which extend from the inner face 13 have a greater length than the protuberances 16 which extend from the outer face 14.
• the protuberances are all elongated and rectilinear. It can of course be expected that at least some of the protuberances have another general shape, for example a curved shape, wavy or loop.
• the protuberances 15, 16 here form a single piece with the core 10. It can be expected that this is not the case or that some of the protuberances only form a single piece with the core.
• the sizes of the protuberances are such that the applicator has a generally substantially cylindrical shape (see FIG. 3). This has the particular advantage of promoting regularity in makeup and avoids the presence of portions of the applicator that are prominent, this being likely to cause the user an apprehension approaching the applicator near his eye during makeup.
• protuberances 15, 16 extend all around the core when considering a short stretch of the core. This makes it possible to create a high density of protuberances and thus to further improve the makeup effect.
• this section comprises both long protuberances 15 and short protuberances 16, so that one and the same section of the core makes it possible, by a simple rotation of the applicator around its axis, to obtain at the same time a application of mascara on the eyelashes, the smoothing of this mascara on the eyelashes as well as their combing.
• the cap 3 is aimed at the collar of article 1 and the applicator bathes in the mascara pool and is loaded with mascara. More particularly, the convex internal volume 12 and the protuberances 15 extending from the inner face 14 of the core 10 are loaded with mascara.
• the applicator is closed. The user manipulates the applicator 1 by holding the cap 3 between his fingers and by unscrewing it from the neck.
• the applicator 1 when it leaves the reservoir, passes through the wiper 6 and is wrung out but all or part of the mascara reserve present in the convex internal volume 12 as well as the mascara present on the portion of the long protuberances Present in the internal volume 12 is retained. Mascara is also loaded on the short protuberances but some of the mascara, more important than for the long protuberances, is dewatered.
• the user During use, the user approaches the applicator to her eyelashes makeup them, and uses a conventional makeup movement, essentially vertical and accompanied by a slight rotation of the applicator 1 about its axis 9.
• the long protuberances 15 deposit mascara on the eyelashes and the short protuberances smooth this mascara and separate and paint the eyelashes.
• the core 10 forms a winding around the axis of the applicator can give the latter a certain flexibility according to the characteristics of material and size of the applicator.
• the applicator is locally compressed by the eyelashes, resulting in an output of the mascara present in the convex internal volume 12 at this level.
• the mascara present in volume 12 is thus even more available for makeup.
• the flexibility of the applicator makes makeup more pleasant for the user.
• the shape of the core 10 also allows it to participate in combing and ordering the eyelashes. More particularly, according to the mode of use, it allows the eyelashes to be oriented outwards, which constitutes a particularly desired make-up effect.
• the applicator presented above is here manufactured in one piece. More particularly, this applicator is manufactured by additive synthesis, also called three-dimensional printing.
• any suitable material is suitable for making this applicator.
• This may be a plastic material, for example a polyamide, especially a polyamide 1102, PEBA 2301, or an ABS type resin, or a powder metal such as stainless steel or titanium.
• the material may be rigid but will preferably be elastically flexible. It is It is preferable that the material, in combination with the shape characteristics of the applicator, give it some flexibility.
• a mascara applicator is generally less than 20 mm in length.
• the applicator is initially designed on computer-aided design (CAD) software.
• An STL file including the design data of the designed applicator is then exported. These data determine the shape of the applicator.
• Other standard file formats for additive synthesis can be used.
• This file is then processed by software provided by the manufacturer of the machine used to perform the additive synthesis.
• This software cuts the file into sections in the form of a hundred digital images in the SU or BFF format, each of them corresponding to a layer of the model to be printed, that is to say to a section of the applicator 1 taken in a plane perpendicular to the main axis 9 of the applicator.
• This data is then sent to the printer to produce the applicator.
• treatments can be applied to the applicator, for example to improve the appearance.
• the embodiment disclosed is directed to a mascara applicator but the same features can be envisioned on an applicator of another cosmetic product for the eyelashes, or a cosmetic product for the eyebrows, skin, nails or lips.
• an applicator of elongated oval overall shape has been presented but it is conceivable that the applicator has another general shape, for example a general frustoconical shape.
