Definitions
- the present invention relates to a device for applying a product, such as, for example, a cosmetic product (e.g., make-up) and/or a care product, to the skin, hair, eyelashes, fingernails, and/or toe nails.
- a product such as, for example, a cosmetic product (e.g., make-up) and/or a care product
- the device may be used to apply cosmetic products such as those defined in Counsel Directive 93/35/EEC (European Economic Community) dated Jun. 14, 1993, which provides merely one example of a definition of cosmetic products and should not be considered as limiting.
- the present invention also relates, for example, to a fiber used for applying a substance and/or a fiber used as a filler in a substance.
- the invention includes a device for applying a product.
- the device includes a plurality of fibers for applying the product.
- At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of an amount of a liquid having a weight at least equal to a weight of the particles and a compound in solution in a liquid, and dissolving in a liquid.
- the particles may lack cotton.
- the weight of the particle prior to being placed in contact with a liquid is compared to the weight of the given particle after having been placed in contact with the liquid for a period of time such that further contact with the liquid does not result in an appreciable amount of additional liquid being absorbed.
- the difference in the weight of the particle prior to contacting the liquid and the particle's weight after absorbing the liquid for a period of time represents the weight of the liquid absorbed.
- the term “fiber” means any generally elongate body (e.g., a bristle of a brush (e.g., a bristle of a mascara brush, nail varnish brush, paint brush, or blusher brush), a fiber in a flocking, a bristle in a paint brush, a fiber for applying a powder, fibers included in a filler for a product intended to be applied to the eyelashes (e.g., for lengthening the eyelashes)).
- the fibers may be relatively flexible, for example, elastically deformable, and the fibers may comprise a synthetic material.
- liquid means any liquid that is acceptable for use in either a cosmetic product and/or a care product, including, for example, but not limited to, water, an oil, an aqueous solution, an alcohol solution, or an oil solution that can be applied on the human body. Such liquid may be contained in the product to be applied. It is not necessary, however, that the liquid be contained in the product.
- a device for applying a product including a plurality of fibers for applying the product.
- At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid.
- the particles may lack clay, may lack silica, and may lack cotton.
- a device for applying a product including a plurality of fibers for applying the product.
- At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid.
- the at least one fiber may be substantially untapered and the particles may lack clay, may lack silica, and may lack cotton.
- at least one of the fibers may have a diameter ranging from about 0.5 ⁇ m to about 500 ⁇ m.
- a fiber for a device for applying a product including a synthetic material, and particles associated with the synthetic material.
- the particles may be configured to be capable of at least one of absorbing at least one of an amount of a liquid having a weight at least equal to a weight of the particles and a compound in solution in a liquid, and dissolving in a liquid.
- the particles may lack cotton.
- a fiber for a device for applying a product including a synthetic material and particles associated with the synthetic material.
- the particles may be configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid.
- the particles may lack clay, may lack silica, and may lack cotton.
- a fiber for a device for applying a product may be provided including a synthetic material and particles associated with the synthetic material.
- the particles may be configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid.
- the fiber may be substantially untapered and the particles may lack clay, may lack silica, and may lack cotton.
- At least one of the fibers may have a cross-section that is substantially constant, and at least one of the fibers may be formed by one of extruding and co-extruding at least one of a thermoplastic material and an elastomeric material.
- At least one of the particles may be at the surface of the at least one fiber.
- at least a portion of at least one fiber may include particles only at the surface of the at least one fiber.
- at least one fiber may include particles dispersed throughout the at least one fiber.
- the fiber may be formed by co-extrusion of two materials (e.g., synthetic materials) with one of the materials being filled, for example, with the particles.
- the particles may be present, for example, at least at the surface of at least a portion of the fibers, at the surface only of the fibers, or dispersed throughout the material of the fibers.
- the particles may include a material configured to increase in volume on contact with at least a portion of the product to be applied.
- at least one of the fibers may include a material capable of swelling on contact with at least a portion of the product to be applied.
- the particles may be capable of swelling when coming in contact with a solvent (e.g., water) contained in the product to be applied.
- a solvent e.g., water
- Such an increase in volume may serve to create surface irregularities at the surface of the fiber, which may form zones for retaining the product.
- Such surface irregularities may be desired, for example, when the fibers are used for application purposes and are dipped in a receptacle containing a supply of a cosmetic product and/or a care product.
- the use of particles capable of absorbing liquid, and possibly of swelling in contact therewith, or of dissolving in contact with the liquid may serve to create special zones for anchoring on the fiber the cosmetic product and/or care product to be applied, for example, by affinity of the particles for hydrophilic or lipophilic compounds contained in the product.
- the product may exhibit improved adherence to the fiber and the applicator may be capable of carrying a larger quantity of the product.
- the presence of particles suitable for absorbing liquid and/or for swelling on contact with the liquid may also be useful in retarding the drying out of the cosmetic product and/or care product present on the surface of the fiber.
- the solvent e.g., water
- the solvent contained in the cosmetic product and/or care product may evaporate and the particles which have absorbed the liquid may then release the liquid back into the substance present around the fiber.
- Retarding the drying out of product present on the surface of an applicator fiber may be desired because it may serve not only to enable the applicator to be used for a greater length of time, but it may also retard the drying out when, for example, the applicator is not in contact with the product (e.g., while not being used (e.g., while being protected merely by a protective cap)).
- the particles may be in a crystalline state when dry and may be capable of softening when placed in contact with the liquid contained in the product. This may render the fiber more flexible after absorption of the liquid.
- the nature of the particles and the amount introduced for example, one may form fibers having a desired flexibility.
- the particles may include, but are not limited to, at least one material chosen from polymers that swell in the presence of at least one of water and lipids, super-absorbent reticulated polyacrylates having a high swelling factor in water, polyvinyl alcohols, carboxyvinyl polymers, semi-synthetic derivatives of cellulose, starches, biogums, biosaccharides, scelro-glucanes, casein, phytocolloids, alginates, gelatins, gelanes, xanthans, laponites, silicas, and colloidal silica.
- These particles may, for example, increase their volume upon coming into contact with the product to be applied (e.g., upon coming into contact with water).

- a compound e.g., a compound that swells when placed in contact with a liquid
- FIG. 1B shows the fiber of FIG. 1A after it has contacted the liquid.
- the fiber 11 may be solid and may be circular in cross-section. As explained herein, however, the fiber 11 may have other cross-sections.
- the fiber 11 may be formed using an arrangement as shown in FIG. 10.
- Such an exemplary arrangement may comprise an extruder 20 and a bath 21 of liquid (e.g., a cooling liquid) into which the fibers 11 may be immersed upon leaving the extruder 20 .
- liquid e.g., a cooling liquid
- the swelling of the particles 30 may serve to produce a relief effect on the surface of the fiber 11 .
- a relief may be useful, for example, for enabling the fiber 11 to pick up a greater quantity of a product (e.g., a cosmetic product and/or a care product) or for improving the ability of the fiber 11 to catch hold of eyelashes, for example, when the fiber 11 is being used as a bristle in a mascara brush.
- the particles 30 may also be useful for absorbing one or more substances within the fiber 11 (e.g., preservatives and/or agents that are cosmetically and/or dermatologically active). For example, referring to FIGS.
- the bath 21 used for cooling the fibers 11 upon leaving the extruder 20 may include one or more compounds that may be soluble in the liquid of the bath 21 (e.g., preservatives), and the compounds may be absorbed by the particles 30 when the fibers 11 are contacted with the liquid of bath 21 .
- the fibers 11 leaving the bath 21 may be substantially filled with compounds which have been absorbed by the particles 30 contained in the fibers 11 .
- These compounds may be released progressively on contact with a product (e.g., a cosmetic product and/or a care product) in order to improve, for example, conservation of the product.
- the fibers 11 may optionally be dehydrated on leaving the bath 21 .
- the fibers 11 may contain particles 40 that are soluble in liquid (e.g., the bath 21 of the liquid (e.g., water) used for cooling the fibers 11 on leaving the extruder 20 ).
- Particles 40 may comprise, for example, a salt, a sugar that is soluble in the liquid used, or a gelatin, when the liquid is water.

- FIG. 1 shows a fiber 11 containing particles 40 prior to being dissolved (e.g., immediately after leaving the extruder 20 )
- FIG. 2B shows the fiber 11 of FIG. 2A after passing through the bath 21 .
- the soluble particles 20 that were present at the surface of the fiber 11 have been dissolved by the liquid of the bath 21 , thereby creating roughness at the surface of the fiber 11 .
- the roughness may result in the fiber 11 being porous.
- Such roughness or porosity may be used, for example, for increasing the amount of a product that the fiber 11 can pick up.
- the amount of roughness or porosity obtained may depend on the initial grain size of the particles 40 . Only a portion of the particles 40 may dissolve when the fiber 11 leaves the bath 21 . In such case, the particles 11 may continue to dissolve upon contacting a product (e.g., a cosmetic product and/or a care product) present on the surface of the fiber 11 .
- a product e.g., a cosmetic product and/or a care product
- the particles 40 may comprise one or more substances having a cosmetic and/or a dermatological effect. Under such circumstances, the dissolution of the particles 40 upon contacting the product may be accompanied by the substances (i.e., the substances having a cosmetic and/or a dermatological effect) being released onto the treated surface.
- the fibers 11 may also be exposed to shocks causing and/or facilitating the removal of at least a portion of the particles 40 present at the surface of the fiber 11 .
- the particles 40 may alternatively comprise a material which is not soluble in the liquid (e.g., water) of the bath 21 , but which is soluble, for example, progressively, upon contacting a product to be applied (e.g., a cosmetic product and/or a care product).
- a product to be applied e.g., a cosmetic product and/or a care product.
- a layer of gel 51 may modify the affinity of the fiber 11 to contact the product.
- the layer of gel 51 may also become deposited on the treated surface (e.g., the eyelashes) so as to improve the firmness and/or the appearance of the treated surface, and/or so as to improve the sliding of the applicator on the treated surface.
- the use of particles capable of absorbing a liquid may also be advantageous for retarding the drying of a product (e.g., a cosmetic product and/or a care product) on the surface of the fiber 11 , for example, when the liquid absorbed by the particles is capable of being released progressively in order to compensate for the evaporation of any solvent contained in the composition.
- a product e.g., a cosmetic product and/or a care product
- particles 30 , 40 , and/or 50 may also serve to create privileged anchor zones on the surface of the fiber 11 for the product to be applied, for example, because of the particles' affinity for lipophilic and/or hydrophilic compounds contained in the product.
- the product may be a water/oil emulsion and the fibers 11 may absorb only water, or only oil, or more generally, they may absorb one of the components of the product in a selective manner.
- the particles 30 , 40 , and/or 50 may be present solely on the surface of the fibers 11 , as shown in FIG. 4.
- the initial grain size of the particles 30 , 40 , and/or 50 may range from about 1 ⁇ m to about 300 ⁇ m, for example, from about 5 ⁇ m to about 200 ⁇ m, or from about 10 ⁇ m to about 150 ⁇ m.

- the fibers 11 may include magnetic particles 12 (e.g., particles configured to generate a magnetic field) dispersed in a substantially uniform manner within the material of the fiber 11 .
- the magnetic particles 12 may alternatively be located solely at the surface of the fiber 11 , by a suitable technique (e.g., by coating as shown in FIG. 8A), or the magnetic particles 12 may be located inside the fiber 11 , as shown in FIG. 8B. It may also be possible to replace the magnetic particles 12 with a central core 14 having magnetic properties, as shown in FIG. 8C.
- the concentration by weight of magnetic particles 12 may range from, for example, about 0.2% to about 30%.

- the fibers 11 may also be magnetized after the fibers 11 have been incorporated into an applicator device by subjecting the device, or a batch of such devices, to a magnetizing field. By magnetizing the fibers 11 once they have been placed into an applicator device, it may be possible to limit any risk of the fibers 11 clumping together.

Abstract
The disclosure relates to a fiber and a product application device including a plurality of fibers for applying a product. In one disclosed example of the device, at least one of the fibers includes particles configured to be capable of at least one of absorbing at least one of an amount of a liquid having a weight at least equal to a weight of the particles and a compound in solution in a liquid, and dissolving in a liquid. The particles may lack cotton.
Description
- The present invention relates to a device for applying a product, such as, for example, a cosmetic product (e.g., make-up) and/or a care product, to the skin, hair, eyelashes, fingernails, and/or toe nails. For example, the device may be used to apply cosmetic products such as those defined in Counsel Directive 93/35/EEC (European Economic Community) dated Jun. 14, 1993, which provides merely one example of a definition of cosmetic products and should not be considered as limiting. The present invention also relates, for example, to a fiber used for applying a substance and/or a fiber used as a filler in a substance.
- There exists a need to improve the ease with which fibers, for example, fibers of a brush or a flocking, can take up a relatively large quantity of a product, for example, in order to enable an applicator comprising at least some of the fibers to continue to be used for a greater period of time.
- There also exists a need for bristles in a mascara brush to be capable of catching hold of the eyelashes, for example, in order to smooth out the product on the surface of the eyelashes and/or in order to curve them. There also exists a need to improve conservation of a cosmetic product and/or a care product. There also exists a need to create novel conditions of application for a cosmetic product and/or a care product by means of fibers, and to create novel makeup effects. There also exists a need to reduce the rate at which a cosmetic product and/or a care product dries out on an applicator, for example, when the applicator is not reinserted quickly into its receptacle or when the applicator is kept in moist conditions via a leaktight cap.
- Although the present invention may obviate one or more shortcomings of the related art, it should be understood that some aspects of the invention might not necessarily obviate one or more of those shortcomings.
- In the following description, certain aspects of the invention will become evident. It should be understood that those aspects are intended to be exemplary and that the invention, in its broadest sense, could be practiced without having one or more of these aspects.
- In one aspect, as embodied and broadly described herein, the invention includes a device for applying a product. The device includes a plurality of fibers for applying the product. At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of an amount of a liquid having a weight at least equal to a weight of the particles and a compound in solution in a liquid, and dissolving in a liquid. The particles may lack cotton.
- When determining the amount of liquid absorbed by a given particle, the weight of the particle prior to being placed in contact with a liquid is compared to the weight of the given particle after having been placed in contact with the liquid for a period of time such that further contact with the liquid does not result in an appreciable amount of additional liquid being absorbed. The difference in the weight of the particle prior to contacting the liquid and the particle's weight after absorbing the liquid for a period of time represents the weight of the liquid absorbed.
- As used herein, the term “fiber” means any generally elongate body (e.g., a bristle of a brush (e.g., a bristle of a mascara brush, nail varnish brush, paint brush, or blusher brush), a fiber in a flocking, a bristle in a paint brush, a fiber for applying a powder, fibers included in a filler for a product intended to be applied to the eyelashes (e.g., for lengthening the eyelashes)). The fibers may be relatively flexible, for example, elastically deformable, and the fibers may comprise a synthetic material.
- As used herein, the term “liquid” means any liquid that is acceptable for use in either a cosmetic product and/or a care product, including, for example, but not limited to, water, an oil, an aqueous solution, an alcohol solution, or an oil solution that can be applied on the human body. Such liquid may be contained in the product to be applied. It is not necessary, however, that the liquid be contained in the product.
- In yet another aspect, a device for applying a product may be provided including a plurality of fibers for applying the product. At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid. The particles may lack clay, may lack silica, and may lack cotton.
- In another aspect, a device for applying a product may be provided including a plurality of fibers for applying the product. At least one of the fibers may include particles configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid. The at least one fiber may be substantially untapered and the particles may lack clay, may lack silica, and may lack cotton. In still a further aspect, at least one of the fibers may have a diameter ranging from about 0.5 μm to about 500 μm.
- According to yet another aspect, a fiber for a device for applying a product may be provided including a synthetic material, and particles associated with the synthetic material. The particles may be configured to be capable of at least one of absorbing at least one of an amount of a liquid having a weight at least equal to a weight of the particles and a compound in solution in a liquid, and dissolving in a liquid. The particles may lack cotton.
- In still another aspect, a fiber for a device for applying a product may be provided including a synthetic material and particles associated with the synthetic material. The particles may be configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid. The particles may lack clay, may lack silica, and may lack cotton.
- In a further aspect, a fiber for a device for applying a product may be provided including a synthetic material and particles associated with the synthetic material. The particles may be configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid. The fiber may be substantially untapered and the particles may lack clay, may lack silica, and may lack cotton.
- In an additional aspect, at least one of the fibers may have a cross-section that is substantially constant, and at least one of the fibers may be formed by one of extruding and co-extruding at least one of a thermoplastic material and an elastomeric material.
- In one aspect, at least one of the particles may be at the surface of the at least one fiber. In a further aspect, at least a portion of at least one fiber may include particles only at the surface of the at least one fiber. In yet another aspect, at least one fiber may include particles dispersed throughout the at least one fiber. The fiber may be formed by co-extrusion of two materials (e.g., synthetic materials) with one of the materials being filled, for example, with the particles. The particles may be present, for example, at least at the surface of at least a portion of the fibers, at the surface only of the fibers, or dispersed throughout the material of the fibers.
- In another aspect, the particles may include a material configured to increase in volume on contact with at least a portion of the product to be applied. For example, at least one of the fibers may include a material capable of swelling on contact with at least a portion of the product to be applied. The particles may be capable of swelling when coming in contact with a solvent (e.g., water) contained in the product to be applied. Such an increase in volume may serve to create surface irregularities at the surface of the fiber, which may form zones for retaining the product. Such surface irregularities may be desired, for example, when the fibers are used for application purposes and are dipped in a receptacle containing a supply of a cosmetic product and/or a care product.
- The use of particles capable of absorbing liquid, and possibly of swelling in contact therewith, or of dissolving in contact with the liquid, may serve to create special zones for anchoring on the fiber the cosmetic product and/or care product to be applied, for example, by affinity of the particles for hydrophilic or lipophilic compounds contained in the product. The product may exhibit improved adherence to the fiber and the applicator may be capable of carrying a larger quantity of the product.
- The presence of particles suitable for absorbing liquid and/or for swelling on contact with the liquid may also be useful in retarding the drying out of the cosmetic product and/or care product present on the surface of the fiber. The solvent (e.g., water) contained in the cosmetic product and/or care product may evaporate and the particles which have absorbed the liquid may then release the liquid back into the substance present around the fiber. Retarding the drying out of product present on the surface of an applicator fiber may be desired because it may serve not only to enable the applicator to be used for a greater length of time, but it may also retard the drying out when, for example, the applicator is not in contact with the product (e.g., while not being used (e.g., while being protected merely by a protective cap)).
- The particles may be in a crystalline state when dry and may be capable of softening when placed in contact with the liquid contained in the product. This may render the fiber more flexible after absorption of the liquid. By selecting the nature of the particles and the amount introduced, for example, one may form fibers having a desired flexibility.
- In yet another aspect, the particles may include, but are not limited to, at least one material chosen from polymers that swell in the presence of at least one of water and lipids, super-absorbent reticulated polyacrylates having a high swelling factor in water, polyvinyl alcohols, carboxyvinyl polymers, semi-synthetic derivatives of cellulose, starches, biogums, biosaccharides, scelro-glucanes, casein, phytocolloids, alginates, gelatins, gelanes, xanthans, laponites, silicas, and colloidal silica. These particles may, for example, increase their volume upon coming into contact with the product to be applied (e.g., upon coming into contact with water).
- In another aspect, at least some of the particles may include one or more super-absorbent materials that may be capable of absorbing twice their weight, ten times their weight, fifty times their weight, one-hundred times their weight, or as much as five-hundred times their weight in liquid.
- In a further aspect, the particles may have a grain size ranging from about 0.1 μm to about 300 μm prior to swelling. For example, the particles may have a grain size ranging from about 5 μm to about 200 μm, or from about 10 μm to about 150 μm. The grain size of the particles may be selected, for example, as a function of the degree of roughness of the fiber desired after swelling. The particles may be formed of a material that is capable of swelling when placed in contact with the product to be applied and which, for example, presents a relative increase in volume of about 15%.
- In yet another aspect, the concentration by weight of the particles prior to swelling relative to the total weight of the at least one fiber may range from above about 0% to about 20%. For example, the concentration by weight of the particles prior to swelling relative to the total weight of the at least one fiber may range from above about 0% to about 6%.
- In still another aspect, at least one of the fibers may include at least one plastic material chosen from polyamides, polyethylene terephthalates (PETs), acetates, polyethylenes (PEs), polypropylenes (PPs), polyvinylchlorides (PVCs), amide block polyesters, plasticized RILSAN (which is believed to be a form of polyamide), elastomers, polyester elastomers, PE elastomers, silicone elastomers, and nitril elastomers. The fibers may also include other materials.
- According to another aspect, the particles may be configured to be capable of forming a gel at the surface of the at least one fiber, and/or may be configured to be capable of dissolving on contact with a liquid. For example, at least one of the particles may be one of hydrosoluble and liposoluble. The dissolution of such particles may result in surface roughness on the fiber and/or render the fiber substantially porous.
- In another aspect, the particles may be configured to be capable of absorbing a liquid. For example, at least one of the fibers may include particles suitable for absorbing a liquid such as water with or without swelling. The use of such particles may be desired for enabling one or more compounds to be introduced into the fiber (e.g., for imparting biocidal and/or bactericidal properties to the fiber). In another aspect, the particles may be configured to be capable of absorbing preservatives in solution in a liquid, for example, in an aqueous solution.
- In an additional aspect, the concentration by weight of the particles prior to contact with a liquid relative to the total weight of the at least one fiber may range from above about 0% to about 20%. For example, the concentration by weight of the particles prior to contact with a liquid relative to the total weight of the at least one fiber may range from above about 0% to about 6%.
- In still a further aspect, the cross-section of at least one of the fibers may have at least one shape chosen from circularly symmetrical shapes, circular shapes, solid square shapes, hollow square shapes, disk shapes, disk shapes having a groove, solid triangle shapes, hollow triangle shapes, solid star shapes, hollow star shapes, U-shaped, V-shaped, I-shaped, T-shaped, Z-shaped, dash-shaped, cross-shaped, kidney-shaped, shapes having three branches, and hollow shapes. The at least one fiber may have a cross-section shape that is twisted.
- In one exemplary embodiment, the device may include a wiper member. The device may be configured to be loaded with the product and may be, for example, a mascara brush including a plurality of bristles. At least one of the bristles may include at least one of the fibers according to any of the previously mentioned aspects. The presence of particles configured to be capable of absorbing liquid and/or capable of swelling upon being placed in contact with a liquid or of dissolving in a liquid may render it possible to impart a degree of roughness and/or porosity to the bristles of a brush, thereby encouraging, for example, adherence of mascara to the bristles and thereby retarding drying out of the mascara. The particles (e.g., when they are suitable for generating films) may also deposit a film on the surface of the eyelashes, thereby improving, for example, the firmness and/or the appearance of the eyelashes, and/or encouraging sliding of the applicator on the eyelashes.
- According to yet another aspect, the device may include a paintbrush including a plurality of bristles. At least one of the bristles may include at least one of the fibers according to any of the previously mentioned aspects. In an additional aspect, the device may include a flocking comprising a plurality of the fibers according to any of the previously mentioned aspects. The device may be configured so that the flocking covers at least a portion of one of teeth, bristles, a wiper, a foam member, a porous member, a film, a perforated film, an endpiece, a woven fabric, and a non-woven fabric.
- The fibers may alternatively be included as at least a portion of a filler in a cosmetic product and/or a care product (e.g., a mascara in which the fibers may contribute to lengthening the eyelashes). Incorporating particles configured to be capable of absorbing a liquid and/or of swelling in contact therewith in the fibers may contribute to improving the retention of the fibers on the eyelashes.
- In one aspect of the device, at least one of the fibers may include at least one of at least one magnetized particle and at least one magnetizable particle. The magnetized and/or magnetizable particles may be included in fibers that contain particles capable of absorbing a liquid, particles capable of swelling on contact with a liquid, and/or particles capable of dissolving in a liquid. The device may have at least some fibers including substantially only magnetic and/or magnetizable particles, and other fibers may include particles capable of absorbing a liquid, particles capable of swelling on contact with a liquid, and/or particles capable of dissolving in a liquid. The magnetic and/or magnetizable particles may be particles coated in a resin (e.g., cyanoacrylate), or they may be formed by depositing a magnetic material on a non-magnetic medium (e.g., a microbead of glass or a wood fiber). Fibers having magnetic properties may improve extraction of the product, may improve application of the product to a treated surface, and/or may create novel makeup effects. The magnetic properties may also encourage penetration of active agents by encouraging microcirculation. The fibers may be stationary or moving.
- In an additional aspect, a method of manufacturing a device for applying a product may include extruding a fiber including a plastics material and particles. The particles may be configured to be capable of at least one of absorbing at least one of a liquid and a compound in solution in a liquid, and dissolving in a liquid. The method may further include placing the fiber and a liquid in contact with one another. The extruding may include co-extruding. The particles may swell on contact with the liquid. The particles may have a grain size selected such that a predefined degree of roughness is imparted to the fiber after the particles have swollen.
- In another aspect, the method may include absorbing a preservative in solution in the liquid. The liquid may cool the fibers and at least a portion of the liquid may be at least one of a cosmetic product and a care product. Alternatively, the liquid may not be the product to be applied by the device or a portion of the product.
- Aside from the structural and procedural arrangements set forth above, the invention could include a number of other arrangements, such as those explained hereinafter. It is to be understood, that both the foregoing description and the following description are exemplary.

- Reference will now be made in detail to some possible embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
- FIGS. 1A through 9Q show numerous exemplary embodiments of fibers according certain aspects of the invention which are suitable for use in a device for applying a product (e.g., the devices shown in FIGS.12 to 26).
- According to exemplary embodiments of a fiber, the fibers may be made by extruding a material11 (e.g., a thermoplastic material) containing a filler of particles (e.g., particles that are capable of absorbing a liquid and/or a compound in solution in the liquid, and/or particles that are capable of dissolving in a liquid) along with optional filler particles (e.g., particles that have magnetic properties (e.g., particles that are magnetized and/or magnetizable)).
- FIG. 1A is a schematic axial cross-section view of an embodiment of a fiber containing a filler of
particles 30 of a compound (e.g., a compound that swells when placed in contact with a liquid) prior to the fiber being placed in contact with a liquid (e.g., water), and FIG. 1B shows the fiber of FIG. 1A after it has contacted the liquid. In the exemplary embodiment shown, thefiber 11 may be solid and may be circular in cross-section. As explained herein, however, thefiber 11 may have other cross-sections. - According to one exemplary aspect, the
fiber 11 may be formed using an arrangement as shown in FIG. 10. Such an exemplary arrangement may comprise anextruder 20 and abath 21 of liquid (e.g., a cooling liquid) into which thefibers 11 may be immersed upon leaving theextruder 20. - The swelling of the
particles 30 may serve to produce a relief effect on the surface of thefiber 11. Such a relief may be useful, for example, for enabling thefiber 11 to pick up a greater quantity of a product (e.g., a cosmetic product and/or a care product) or for improving the ability of thefiber 11 to catch hold of eyelashes, for example, when thefiber 11 is being used as a bristle in a mascara brush. Theparticles 30 may also be useful for absorbing one or more substances within the fiber 11 (e.g., preservatives and/or agents that are cosmetically and/or dermatologically active). For example, referring to FIGS. 10 and 11, it may possible for thebath 21 used for cooling thefibers 11 upon leaving theextruder 20 to include one or more compounds that may be soluble in the liquid of the bath 21 (e.g., preservatives), and the compounds may be absorbed by theparticles 30 when thefibers 11 are contacted with the liquid ofbath 21. In this manner, thefibers 11 leaving thebath 21 may be substantially filled with compounds which have been absorbed by theparticles 30 contained in thefibers 11. These compounds may be released progressively on contact with a product (e.g., a cosmetic product and/or a care product) in order to improve, for example, conservation of the product. Thefibers 11 may optionally be dehydrated on leaving thebath 21. - Alternatively, in addition to the
particles 30, thefibers 11 may containparticles 40 that are soluble in liquid (e.g., thebath 21 of the liquid (e.g., water) used for cooling thefibers 11 on leaving the extruder 20).Particles 40 may comprise, for example, a salt, a sugar that is soluble in the liquid used, or a gelatin, when the liquid is water. FIG. 2A shows afiber 11 containingparticles 40 prior to being dissolved (e.g., immediately after leaving the extruder 20), and FIG. 2B shows thefiber 11 of FIG. 2A after passing through thebath 21. FIG. 2B illustrates one example in which thesoluble particles 20 that were present at the surface of thefiber 11 have been dissolved by the liquid of thebath 21, thereby creating roughness at the surface of thefiber 11. In some embodiments, the roughness may result in thefiber 11 being porous. Such roughness or porosity may be used, for example, for increasing the amount of a product that thefiber 11 can pick up. The amount of roughness or porosity obtained may depend on the initial grain size of theparticles 40. Only a portion of theparticles 40 may dissolve when thefiber 11 leaves thebath 21. In such case, theparticles 11 may continue to dissolve upon contacting a product (e.g., a cosmetic product and/or a care product) present on the surface of thefiber 11. Theparticles 40 may comprise one or more substances having a cosmetic and/or a dermatological effect. Under such circumstances, the dissolution of theparticles 40 upon contacting the product may be accompanied by the substances (i.e., the substances having a cosmetic and/or a dermatological effect) being released onto the treated surface. Thefibers 11 may also be exposed to shocks causing and/or facilitating the removal of at least a portion of theparticles 40 present at the surface of thefiber 11. - The
particles 40 may alternatively comprise a material which is not soluble in the liquid (e.g., water) of thebath 21, but which is soluble, for example, progressively, upon contacting a product to be applied (e.g., a cosmetic product and/or a care product). - According to another aspect, it may be possible to introduce
particles 50 into thefiber 11 that are suitable for gelling upon contact with a liquid so as to form a layer ofgel 51 on the surface of thefiber 11, as shown in FIG. 3. Such a layer ofgel 51 may modify the affinity of thefiber 11 to contact the product. The layer ofgel 51 may also become deposited on the treated surface (e.g., the eyelashes) so as to improve the firmness and/or the appearance of the treated surface, and/or so as to improve the sliding of the applicator on the treated surface. - The use of particles capable of absorbing a liquid (e.g., water) may also be advantageous for retarding the drying of a product (e.g., a cosmetic product and/or a care product) on the surface of the
fiber 11, for example, when the liquid absorbed by the particles is capable of being released progressively in order to compensate for the evaporation of any solvent contained in the composition. - The use of
particles fiber 11 for the product to be applied, for example, because of the particles' affinity for lipophilic and/or hydrophilic compounds contained in the product. The product may be a water/oil emulsion and thefibers 11 may absorb only water, or only oil, or more generally, they may absorb one of the components of the product in a selective manner. - According to one exemplary embodiment, the
particles fibers 11, as shown in FIG. 4. - According to one aspect, the initial grain size of the
particles particles - According to another aspect, the
fibers 11 may include magnetic particles 12 (e.g., particles configured to generate a magnetic field) dispersed in a substantially uniform manner within the material of thefiber 11. Themagnetic particles 12 may alternatively be located solely at the surface of thefiber 11, by a suitable technique (e.g., by coating as shown in FIG. 8A), or themagnetic particles 12 may be located inside thefiber 11, as shown in FIG. 8B. It may also be possible to replace themagnetic particles 12 with a central core 14 having magnetic properties, as shown in FIG. 8C. The concentration by weight ofmagnetic particles 12 may range from, for example, about 0.2% to about 30%. - The magnetic material for the
magnetic particles 12 may at least partially include at least one material chosen from soft magnetic materials, hard magnetic materials, ferrites, ferrites based on zinc, ferrites based on nickel, ferrites based on manganese, rare earth elements, barium sulfates, silicon iron alloys, cobalt irons, and cobalt irons filled with molybdenum. Themagnetic particles 12 may be formed, for example, by fragmenting a magnetic substance or by depositing a magnetic substance M on a non-magnetic body C (e.g., a microbead or a wood fiber) as shown in FIG. 31. Theparticles 12 may also be configured in the form of magnetic cores M having non-magnetic outer coverings R (e.g., a layer of resin, for example, a layer of cyanoacrylate), as shown in FIG. 32. - FIGS. 5A and 5B show a
fiber 11 which differs from that of FIGS. 1A and 1B at least by havingmagnetic particles 12 present within thefiber 11. FIGS. 6A and 6B substantially correspond to afiber 11 which differs from that of FIGS. 2A and 2B at least by the presence ofmagnetic particles 12. FIG. 7 shows substantially thefiber 11 of FIG. 3 havingmagnetic particles 12 dispersed throughoutfiber 11. - As described below with reference to FIGS. 9A through 9Q, the
fibers 11 may have a wide variety of cross-sections. Thefibers 11 may be formed (e.g., by extrusion) to have a substantially flat cross-section as shown in FIG. 9A, a cross-shaped section as shown in FIG. 9B, or a three-branch star shape as shown in FIG. 9C. The cross-section of thefibers 11 may also be hollow as shown in FIG. 9D, or solid with a capillary groove as shown in FIG. 9E. Thefibers 11 may also have a cross-section that is U-shaped, as shown in FIG. 9F; I-shaped, as shown in FIG. 9H; C-shaped, as shown in FIG. 9I; V-shaped, as shown in FIG. 9J; Z-shaped, as shown in FIG. 9K; or a combination of the these shapes (e.g., the combination shown in FIG. 9G which combines the shapes that correspond to FIGS. 9B and 9C). FIG. 9L shows an exemplary fiber having a hollow square cross-section; FIG. 9M shows an exemplary fiber having a solid square cross-section; FIG. 9N shows an exemplary fiber having a hollow star-shaped cross-section; FIG. 9O shows an exemplary fiber having a hollow triangular cross-section; FIG. 9P shows an exemplary fiber having a cross-section that forms peripheral grooves; and FIG. 9Q shows an exemplary fiber having a kidney-shaped cross-section. - The
fibers 11 may be exposed to a magnetic field for magnetizing thefibers 11 upon leaving thebath 21 by means of, for example, a magnetizingapparatus 60, as shown in FIG. 11, so as to magnetize thefibers 11 with a predefined polarity. According to an exemplary embodiment, thefibers 11 may also be magnetized after thefibers 11 have been incorporated into an applicator device by subjecting the device, or a batch of such devices, to a magnetizing field. By magnetizing thefibers 11 once they have been placed into an applicator device, it may be possible to limit any risk of thefibers 11 clumping together. - The
fibers 11 may also be used in a variety of devices as described herein. For example, FIG. 12 shows anapplicator device 100 comprising areceptacle 101 for containing a product P for application (e.g., a mascara) and anapplicator 102. Thereceptacle 101 may be provided with awiper member 106 which, in an exemplary embodiment not shown, may be provided with flocking. Theapplicator 102 may include astem 103 provided at one end with ahandle member 104 that may also constitute a cap for closing thereceptacle 101. Abrush 105 may be provided at the opposite end of theapplicator 102. Thebrush 105 may include a core comprising twisted wire with bristles being held in the turns of the twisted wire core. The bristles may comprisefibers 11 configured to generate a magnetic field, for example. Alternatively, the bristles might lack any magnetic properties. - The magnetic poles of the
brush 105 may be oriented either along the axis of thestem 103 or perpendicularly to the axis of thestem 103, for example. The twisted core may be formed from a non-magnetic material (e.g., a non-magnetic stainless steel) or in another embodiment, the twisted wire core may be formed from a material having magnetic properties. The core may thus interact magnetically with the bristles. The bristles of thebrush 105 may be magnetized such that the magnetization of a bristle of thebrush 105 acts on adjacent bristles with the magnetic interactions between the bristles being used, for example, to orient the bristles in a desired manner. Depending on the orientation of the magnetic poles of thebrush 105, the effect on the orientation of the bristles may differ. For example, FIGS. 28A and 28B show one effect of the bristles of thebrush 105 being deflected in the presence of a transverse magnetic field. - The magnetization of the bristles may also be used, during application of a product onto the eyelashes, for example, for the purpose of applying a magnetic field whose action is beneficial on the eyelashes or on some other part of the face (e.g., the eyelids). The magnetic field exerted by the bristles of the
brush 105 may vary over time, for example, when the shape of thebrush 105 is altered (e.g., while the applicator is being withdrawn from a receptacle or during application of the product). - The product P may present magnetic properties (e.g., the product P may contain particles that are magnetized and/or that are magnetizeable). When the product P presents magnetic properties, a brush having bristles which may be configured to generate a magnetic field may encourage loading of the brush with the product P (i.e., by the product P being attracted to the bristles of the brush). The product P may also contain fibers or flakes having magnetic properties and the applicator may interact magnetically with the flakes, for example, to put them into a particular orientation at the time of application (e.g., to encourage sliding of the applicator during application).
- FIG. 13 shows an exemplary embodiment of a
device 110 for applying a product (e.g., nail varnish). Thedevice 110 may comprise areceptacle 111 and anapplicator 112 comprising astem 113 provided at one end with ahandle member 114 that may also constitute a cap for closing thereceptacle 111. The other end of theapplicator 112 may be provided with a bristle tuft 115 (e.g., in the form of a paint brush) comprising a bundle of bristles placed close together. The bristles may be formed from fibers presenting magnetic properties, which may be useful for bringing the bristles of thetuft 115 into a predefined orientation so as to make it easier to load product onto thetuft 115 and/or so as to exert an action on the treated surface. Magnetic interactions between the bristles of thetuft 115, depending on the polarity of the magnetic field of each bristle, may contribute either to bunching the bristles together or to splaying them apart. For example, FIGS. 29A and 29B are schematic representations of one possible effect (i.e., the effect of the bristles being splayed apart due to magnetic interactions between the bristles). The product P may also present magnetic properties. - FIG. 14 shows an exemplary embodiment of an
applicator device 120 which may comprise areceptacle 121 containing a product P (e.g., a liquid lipstick) and anapplicator 122 comprising astem 123 provided at one end with acap 124 for closing thereceptacle 121 which may also serve as a handle, and at its other end with anapplicator endpiece 124 covered in flocking comprising fibers that are configured to generate a magnetic field. Thedevice 120 may also include a wiper comprising a block offoam 125. The block offoam 125 may present magnetic properties. For example, the block offoam 125 may be magnetized in a certain direction by incorporating magnetized and/or magnetizable particles within the block offoam 125. Magnetizing the wiper may be used, for example, to magnetize the flocking on theendpiece 124 while theapplicator 122 is being withdrawn from thereceptacle 121. - FIG. 15 shows another exemplary embodiment of an
applicator device 130 for a product P (e.g., a liquid lipstick) that may include anendpiece 131 covered by flocking 132 comprising fibers presenting magnetic properties. - FIG. 16 shows an exemplary embodiment of a
brush 140 for applying a powder, for example, with bristles of the brush being formed using fibers that present magnetic properties. - FIG. 17 shows an exemplary embodiment of an
applicator 150 comprising afoam member 151 covered on its surface by flocking 152 comprising fibers that present magnetic properties. Such an applicator may be used, for example, to apply blush to the skin. - FIG. 18A shows an exemplary embodiment of a
liquid lipstick applicator 160 including anendpiece 161 of material (e.g., an elastomer) provided with flocking, and FIG. 18B shows an exemplary embodiment of aneyeliner 160′ including anendpiece 161′ of material (e.g., an elastomer) provided with flocking. The flocking may comprise fibers presenting magnetic properties. - The fibers may also be used for flocking on an embodiment of a
powder puff 170, as shown in FIG. 19, or for flocking on an exemplary embodiment of a make-upremoval sponge 180, as shown in FIG. 20. The flocking may also extend on afilm 191 fixed on a block offoam 192 of an exemplary embodiment of anapplicator 190, as shown in FIG. 21. - It may also be possible to use fibers that present magnetic properties in a disk or
wiper 200 comprising at least onelayer 201 of a woven or non-woven fabric incorporating such fibers, as shown in FIG. 22. - FIG. 23 shows an exemplary embodiment of a
comb 210 for applying a product to the eyelashes. The comb may includeteeth 211 provided with flocking. The flocking may be formed using fibers having magnetic properties. - According to an exemplary embodiment, an applicator may include one or more one-piece magnets in addition to fibers having magnetic properties. For example, FIG. 24 shows an
applicator 220 comprising ahandle 221 with amagnet 222 fixed thereto. Themagnet 222 may be covered by a block offoam 223. The block offoam 223 may be provided with flocking 224 comprising fibers presenting magnetic properties. The presence of themagnet 222 may subject the flocking 224 to a magnetic field. For example, the flocking having fibers that extend substantially perpendicularly to the underlying support may become oriented along magnetic field lines M, as shown in FIG. 27. The fibers may tend to stand up on the surface of theapplicator 220 or may tend to take on other orientations depending on their position relative to themagnet 222. This may make it possible, for example, to load more product onto theapplicator 220, which may result in making application of the product softer. In addition, when the product is a powder that is brought into contact with theapplicator 220, and when theapplicator 220 has magnetic properties, the particles of powder may tend to become deposited on the applicator 220 (e.g., on its fibers), thereby reducing the risk of the powder being blown about, which may induce sneezing. - FIG. 25 shows an exemplary embodiment of a
device 230 in which the product may be contained in aflexible bag 231 associated with apump 232 mounted thereon. The applicator may include afoam element 234 coated on a surface with flocking 235 and secured to acap 236. Amagnet 237 may be received in thefoam element 234 and may be carried by thecap 236. The flocking 235 may present magnetic properties and may be subjected to the magnetic field of themagnet 237, as described previously herein. - FIG. 30 shows a portion of an
exemplary applicator 280 comprising flocking on anendpiece 282, which may be received in acap 281 when not in use. By using fibers that contain particles which absorb water or which swell in water, it may be possible to maintain moist conditions within thecap 281, such that theendpiece 282 dries out more slowly. In another aspect, theendpiece 282 could be replaced by some other applicator element (e.g., a brush). - Naturally, the invention is not limited to the embodiments described above. For example, it may be possible to provide a
screen 240 between an applicator and a product contained in a receptacle, as shown in FIG. 26. Under such circumstances, the product P may containmagnetic particles 241 and the applicator may present magnetic properties (e.g., because it comprises an endpiece provided with flocking comprising magnetized and/or magnetizable fibers). Theendpiece 242 may be capable of attracting themagnetic particles 241 contained in the product. By selecting a proper mesh size for thescreen 240, it may be possible to ensure that themagnetic particles 241 attracted by theendpiece 242 are substantially prevented from passing through thescreen 240, while still serving to move the product P towards theendpiece 242, thereby improving loading of theendpiece 242 with product. In another aspect, the product P may itself present magnetic properties (e.g., containing coated magnetic particles) and may pass through the mesh of thescreen 240. - In addition, the fibers may be magnetized over only a fraction of their length. The applicator devices described above may include fibers having magnetic properties mixed with fibers that do not have magnetic properties (e.g., fibers that are filled with particles of a material for absorbing liquid (e.g., water), and/or particles suitable for swelling on contact with a liquid, and/or particles capable of dissolving on contact with the liquid).
- The device and system according to some exemplary embodiments of the invention may be used to apply any cosmetic or care products, such as make-up, dermatological, or pharmaceutical compositions used for treating and/or changing the appearance of eyelashes, hair, skin, lips, or nails. However, in its broadest aspects, the present invention could be used to apply many other substances.
- Furthermore, sizes of various structural parts and materials used to make the above-mentioned parts are illustrative and exemplary only, and one of ordinary skill in the art would recognize that these sizes and materials can be changed as necessary to produce different effects or desired characteristics.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the structure and methodology of the present invention. Thus, it should be understood that the invention is not limited to the examples discussed in the specification. Rather, the present invention is intended to cover modifications and variations.
