Definitions

  • the present invention relates to applying makeup to the eyelashes and/or the eyebrows.
  • the invention seeks to obtain an effective lengthening of the eyelashes or other human keratinous fibers .
  • the invention relates more particularly to packaging and applicator devices including an applicator comprising a stem and, at one end thereof, an applicator member for applying the composition to the eyelashes or the eyebrows .
  • compositions filled with fibers for lengthening the eyelashes .
  • Application EP 1 070 465 discloses an applicator device to apply a make-up product to the eyelashes, comprising an application element with at least one row of teeth where the geometric configuration of the teeth allows the eyelashes to be gripped, lengthened, and separated by the teeth.
  • the teeth may be flocked to increases the amount of product with which the application element becomes laden.
  • This document describes several mascara products of fluid to pasty consistency, even a solid cake of product. If the mascara includes fibers, EP 1 070 465 teaches orienting the fibers with the teeth such that the fibers are substantially parallel to the eyelashes as the product is applied.
  • Exemplary embodiments of the invention provide a packaging and applicator assembly for applying makeup to the eyelashes or the eyebrows, said assembly comprising:
  • At least one applicator including a flocked applicator member for applying the composition to the eyelashes or the eyebrows, preferably with at least one applicator element projecting from the applicator member.
  • the user benefits from an applicator that is capable of depositing the fibers in satisfactory manner by means of the presence of the flocking, which flocking reduces the drawbacks encountered in the prior art.
  • Composition including fibers
  • fibers means generally elongate bodies presenting, for example, a form factor lying in the range
  • the form factor is defined by the ratio
  • L L/D, where L is the length of the fiber and D is the diameter of the circle in which the widest cross-section of the fiber is inscribed.
  • the cross-section of the fibers may be inscribed in a circle having a diameter lying in the range 100 nanometers (nm) to 400 micrometers (ym) , better in the range 1 ym to 400 ym, better still in the range 1 ym to 50 ym.
  • the fibers of the composition preferably have a length lying in the range 0.2 millimeters (mm) to 3 mm, better in the range 0.2 mm to 1.5 mm.
  • the composition may comprise a mixture of fibers of different length and/or diameters of cross-section.
  • the fibers may present a weight lying in the range 0.15 denier to 30 denier (weight in grams (g) per 9 kilometers (km) of thread) , better in the range 0.18 denier to 18 denier.
  • the concentration of fibers in the composition lies in the range 100% to about 94% by weight .
  • the container is not filled completely when it is made available to the consumer, in order to leave a free space so as to make it easier to load the applicator member with composition, and distribute the fibers uniformly in the composition, e.g. by shaking the container prior to opening it.
  • the container preferably leaves a free space of volume that is at least equal to one fourth of its total inside volume.
  • the cross-section of the fibers may be of any shape, e.g. circular, or polygonal, in particular square, hexagonal, or octagonal.
  • the fibers may be in the form of glitter or flakes.
  • the composition may include solid or hollow fibers that may be independent or interlinked, e.g. braided.
  • the fibers are free.
  • the term "free fibers" should be understood to mean fibers that are not immersed in a liquid.
  • the fibers may optionally be coated in a binder, e.g. in an amount lying in the range 0.5% to 6% by weight within the composition.
  • the composition may be formed exclusively by the fibers.
  • composition comprising the fibers may not be a lotion, a gel, a solid block.
  • composition comprising the fibers may have the same behavior as a free powder, for example tends to flow by gravity.
  • the composition may include fibers having ends that are blunted and/or rounded.

  • the fibers may be of the same type or they may be of different types.
  • the fibers may be of plant origin, e.g. made of cotton, or of synthetic origin, e.g. made of: polyamide, in particular nylon; acetate; polyethylene terephthalate (PET) ; polyolefin, in particular polyethylene (PE) or polypropylene (PP) ; polyvinyl chloride (PVC) ; polyester block amide; plasticized Rilsan®; elastomer, in particular polyester elastomer, polyethylene (PE) elastomer, silicone elastomer, nitrile elastomer; or a mixture of these materials, this list not being limiting.
  • the composition may include fibers made by extruding or co-extruding one or more polymeric materials, in particular thermoplastics and/or elastomers.
  • the composition may contain composite fibers obtained by covering a synthetic core, or a core of plant or mineral origin, with a synthetic material, the core being composed, for example, of a fiber made of: wood or of another plant material; rayon; polyamide; or polyolefin, in particular polyethylene; Nylon®; polyimide-amide ; or aramid; this list not being limiting.

  • the bristles may be made of: polyamide, e.g. nylon®; polyacrylic; polyester; cotton; or cellulose, e.g. viscose or rayon.
  • the bristles may be selected from bristles of any color.
  • the flocking bristles are fastened to the applicator member, e.g. by means of a layer of adhesive that covers the body of the applicator member, and they are oriented at the surface of the applicator member by an electrostatic field while the adhesive is setting.
  • the flocking is constituted by different flocking bristles, e.g. bristles of shapes and/or dimensions that are different.
  • the difference in shape and/or the difference in length makes it possible to create interstices that are suitable for holding supplies of composition.
  • the mixture may include flocking bristles of different lengths, diameters, and/or sections.
  • the term "diameter” should be understood to mean the diameter of the circle when the section is circular, or else the diameter of the circle that circumscribes the section when it is not circular.
  • the flocking mixture may comprise both straight flocking bristles and curved flocking bristles.
  • the flocking may come from a flocking mixture comprising at least two kinds of flocking having respective mean lengths that are different, in particular a short first flocking and a longer second flocking, the difference between the respective mean lengths of the two kinds of flocking being at least 0.5 mm, for example.

Abstract

The present invention relates to a packaging and applicator assembly (10) for applying a composition (P) to the eyelashes or the eyebrows, said assembly comprising: at least one container (2) containing the composition (P), said composition containing fibers; and at least one applicator (3) including a flocked applicator member (8).

Description

AN ASSEMBLY INCLUDING A COMPOSITION CONTAINING FIBERS FOR MAKING-UP THE EYELASHES.
The present invention relates to applying makeup to the eyelashes and/or the eyebrows.
Numerous devices for applying makeup to the eyelashes claim to obtain an effect of lengthening the eyelashes. Quite often, the lengthening is considered as being the visual impression that results from greater visibility of the eyelashes, associated with coloring them all the way to their tips. Few compositions procure real lengthening of the eyelashes in the sense in which the composition actually adds length to the eyelashes.
The invention seeks to obtain an effective lengthening of the eyelashes or other human keratinous fibers .
The invention relates more particularly to packaging and applicator devices including an applicator comprising a stem and, at one end thereof, an applicator member for applying the composition to the eyelashes or the eyebrows .
It is known, e.g. from application EP 1 264 562, to use compositions filled with fibers for lengthening the eyelashes .
Application EP 1 070 465 discloses an applicator device to apply a make-up product to the eyelashes, comprising an application element with at least one row of teeth where the geometric configuration of the teeth allows the eyelashes to be gripped, lengthened, and separated by the teeth. The teeth may be flocked to increases the amount of product with which the application element becomes laden. This document describes several mascara products of fluid to pasty consistency, even a solid cake of product. If the mascara includes fibers, EP 1 070 465 teaches orienting the fibers with the teeth such that the fibers are substantially parallel to the eyelashes as the product is applied. However, a need exists to improve the application of such compositions containing fibers, so as to deposit the fibers on the eyelashes or the eyebrows in a manner that is satisfactory in terms of quantity and orientation. In practice, the fibers tend to be wiped off the applicator on passing through the wiper member present in the container, and as a result some of the benefit expected of the composition is lost.
In addition, depending on the types of mascara brush and of wiper member used, certain applicators take too many fibers and deposit them in irregular manner on the eyelashes, while, on the contrary, other applicators are wiped too much and deposit almost no fibers. Thus, during application, twisted-core brushes tend to eliminate the fibers previously deposited on the eyelashes, and often such brushes add little composition and few fibers to the eyelashes.
Mascaras are known for application in two steps, using two conventional twisted-core brushes for applying two compositions in succession. EP 1 188 393 discloses a packaging and applicator assembly including two twisted- core brushes of different sizes for applying makeup to eyelashes of different lengths.
Exemplary embodiments of the invention provide a packaging and applicator assembly for applying makeup to the eyelashes or the eyebrows, said assembly comprising:
• at least one container containing a composition containing fibers for application to the eyelashes or the eyebrows; and
· at least one applicator including a flocked applicator member for applying the composition to the eyelashes or the eyebrows, preferably with at least one applicator element projecting from the applicator member.
By means of the invention, the user benefits from an applicator that is capable of depositing the fibers in satisfactory manner by means of the presence of the flocking, which flocking reduces the drawbacks encountered in the prior art.
Composition including fibers
The term "fibers" means generally elongate bodies presenting, for example, a form factor lying in the range
3.5 to 2500, better in the range 5 to 500, e.g. in the range 5 to 150. The form factor is defined by the ratio
L/D, where L is the length of the fiber and D is the diameter of the circle in which the widest cross-section of the fiber is inscribed.
By way of example, the cross-section of the fibers may be inscribed in a circle having a diameter lying in the range 100 nanometers (nm) to 400 micrometers (ym) , better in the range 1 ym to 400 ym, better still in the range 1 ym to 50 ym.
The fibers of the composition preferably have a length lying in the range 0.2 millimeters (mm) to 3 mm, better in the range 0.2 mm to 1.5 mm.
The composition may comprise a mixture of fibers of different length and/or diameters of cross-section.
By way of example, the fibers may present a weight lying in the range 0.15 denier to 30 denier (weight in grams (g) per 9 kilometers (km) of thread) , better in the range 0.18 denier to 18 denier.
By way of example, the concentration of fibers in the composition lies in the range 100% to about 94% by weight .
Preferably, the container is not filled completely when it is made available to the consumer, in order to leave a free space so as to make it easier to load the applicator member with composition, and distribute the fibers uniformly in the composition, e.g. by shaking the container prior to opening it.
Above the composition, the container preferably leaves a free space of volume that is at least equal to one fourth of its total inside volume. The cross-section of the fibers may be of any shape, e.g. circular, or polygonal, in particular square, hexagonal, or octagonal. The fibers may be in the form of glitter or flakes.
The composition may include solid or hollow fibers that may be independent or interlinked, e.g. braided.
In the composition, the fibers are free. The term "free fibers" should be understood to mean fibers that are not immersed in a liquid. The fibers may optionally be coated in a binder, e.g. in an amount lying in the range 0.5% to 6% by weight within the composition. The composition may be formed exclusively by the fibers.
In particular the composition comprising the fibers may not be a lotion, a gel, a solid block.
The composition comprising the fibers may have the same behavior as a free powder, for example tends to flow by gravity.
The composition may include fibers having ends that are blunted and/or rounded.
The shape of the fibers may not be significantly modified when they are inserted into the medium of the composition, with said fibers being initially rectilinear and sufficiently rigid to keep their shape. In a variant, the fibers may present flexibility that enables them to be substantially deformed within the composition.
All of the fibers may be of the same type or they may be of different types. By way of example, the fibers may be of plant origin, e.g. made of cotton, or of synthetic origin, e.g. made of: polyamide, in particular nylon; acetate; polyethylene terephthalate (PET) ; polyolefin, in particular polyethylene (PE) or polypropylene (PP) ; polyvinyl chloride (PVC) ; polyester block amide; plasticized Rilsan®; elastomer, in particular polyester elastomer, polyethylene (PE) elastomer, silicone elastomer, nitrile elastomer; or a mixture of these materials, this list not being limiting. The composition may include fibers made by extruding or co-extruding one or more polymeric materials, in particular thermoplastics and/or elastomers.
The composition may contain composite fibers obtained by covering a synthetic core, or a core of plant or mineral origin, with a synthetic material, the core being composed, for example, of a fiber made of: wood or of another plant material; rayon; polyamide; or polyolefin, in particular polyethylene; Nylon®; polyimide-amide ; or aramid; this list not being limiting.
The fibers may optionally be colored. Preferably, the fibers are black in color or of the color of the medium present around them in the composition.
The fibers may be magnetic or they may include positive or negative charges. The term "magnetic fibers" means fibers that include a magnetic body or particles, e.g. black iron oxides. Applications EP 1 264 562 and EP 1 726 234 describe such fibers. Applicator member
Flocking
The applicator member may be flocked completely or in part. In the meaning of the invention, the term "flocking" means the set of flocking bristles that cover the flocked portion of the applicator member.
Flocked mascara brushes are described in patent FR 2 663 826.
When the applicator member is "completely flocked", all of the visible surface of the applicator member, including the applicator elements, is covered in flocking bristles .
The flocking makes it easier to load the applicator member with composition and with fibers, and makes it possible to retain said fibers while passing through the wiper member. The presence of the flocking also enables application to be very gentle, and also helps to orientate the fibers and make it easier to transfer them to the eyelashes or the eyebrows during application. While applying makeup, if the user passes over a zone of the eyelashes on which fibers have already been deposited, e.g. so as to smooth the composition, the fibers remain more easily on the eyelashes and are less likely to be picked back up by the applicator.
The flocking used may be of any type, including natural types. The flocking may be magnetizable and/or electrically conductive.
The flocking bristles may be treated or may include additives such as for example: slip additives; absorbent agents; anti-UV agents; magnetic or magnetizable particles; bactericidal agents; etc....
The bristles of the flocking of the applicator member may be of the same length, type, shape, and/or section, e.g. being identical.
In a variant, the flocking includes bristles of types, lengths, and/or sections that are different.
The envelope surface of the applicator member, defined by the free ends of the flocking bristles, may be of any shape, in particular optionally circularly symmetrical, cylindrical, egg-shaped, flat, conical, biconical, prismatic. This envelope surface may reveal one or more stripes, a cavity, or even a through opening.
The length of the flocking bristles lies in the range 0.2 mm to 2.5 mm, for example. The diameter of the flocking bristles lies in the range 10 ym to 500 ym, for example .
The flocking bristles may have a cross-section that is: circular; oval; polygonal; cross-shaped; three-lobed; four-lobed; C, E, F, H, I, L, N, S, T, V, W, X, Y, or Z shaped; star shaped; or crescent shaped. The bristles may be made of: polyamide, e.g. nylon®; polyacrylic; polyester; cotton; or cellulose, e.g. viscose or rayon. The bristles may be selected from bristles of any color.
The flocking bristles are fastened to the applicator member, e.g. by means of a layer of adhesive that covers the body of the applicator member, and they are oriented at the surface of the applicator member by an electrostatic field while the adhesive is setting.
Flocking mixture
In these exemplary embodiments of the invention, the flocking is constituted by different flocking bristles, e.g. bristles of shapes and/or dimensions that are different. The difference in shape and/or the difference in length makes it possible to create interstices that are suitable for holding supplies of composition.
In particular, the mixture may include flocking bristles of different lengths, diameters, and/or sections. The term "diameter" should be understood to mean the diameter of the circle when the section is circular, or else the diameter of the circle that circumscribes the section when it is not circular.
The flocking mixture may comprise both straight flocking bristles and curved flocking bristles.
The flocking may come from a flocking mixture comprising at least two kinds of flocking having respective mean lengths that are different, in particular a short first flocking and a longer second flocking, the difference between the respective mean lengths of the two kinds of flocking being at least 0.5 mm, for example. By way of example, the relative proportions by number between two kinds of flocking lies in the range 30/70 to 70/30, e.g. 50/50.
The flocked coating may be obtained by mixing together a greater number of types of bristles.
Furthermore, the surface of the applicator member may be covered in various mixtures of different types. Support for supporting the applicator elements
The applicator member advantageously includes projecting applicator elements that make it possible to separate and to comb the eyelashes.
The applicator elements are connected to a support that is present at the end of a stem of the applicator, for example, the support constituting the body of the applicator member, at least in part.
The applicator member is different from a conventional twisted-core brush. The support may thus be different from a twisted core.
The applicator member may include a support that includes an opening and two opposite regions on which applicator elements may optionally be connected, e.g. in manner similar to that described in European patent EP 1 169 941 or application EP 1 726 234.
In other embodiments, the applicator member may include a support that is of polygonal cross-section and has a plurality of sides and at least two of the projecting applicator elements extend away from the support substantially in continuation of different sides of the support and in different directions from one another. Alternatively, the support may have a non- polygonal cross-section and at least one projecting applicator element extending away from the support such that an axis of the projecting applicator element is in a direction substantially at a tangent to the support where the applicator elements meets the support.
The applicator member may include at least two projecting applicator elements oriented in the same direction of gyration about a longitudinal axis of the support .
Such applicator member are described in patent US 6 343 607. The stem of the applicator and the support may optionally be made out of different materials.
The body of the applicator member and the stem of the applicator may be made as a single part, in particular by injection-molding, or, in a variant, the body of the applicator member may be fitted to the stem. In this fitted configuration, the body of the applicator member may include an endpiece that is arranged to be engaged in a housing of the stem, or vice versa.
In exemplary embodiments, the applicator element (s) and its/their support (s) is/are made as a single part, in particular by molding or by machining. In a variant, the applicator elements are fitted on the support.
The applicator member, in particular the support of the applicator element (s), may be made, at least in part, out of a flexible or rigid material, in particular out of a thermoplastic material, an elastomer, or a thermoplastic elastomer, preferably by molding.
It would not be beyond the ambit of the present invention for the applicator member to be made, at least in part, out of wood or out of metal, or out of still other materials, in particular by machining.
The applicator member may be of longitudinal axis that is optionally rectilinear. For a longitudinal axis that is rectilinear, said longitudinal axis may optionally extend the longitudinal axis of the stem.
The material of the applicator member may include a biocidal compound.
Applicator elements
When present, the applicator element (s) may define one or more portions in relief such as stripes, teeth, pegs, disks, and grooves that may be straight, annular, or helical.
The applicator elements may present various shapes, in particular they may be elongate in shape, e.g. peg or tooth shaped, e.g. a peg shape that is cylindrical of optionally-circular cross-section, conical, frustoconical , or pyramidal, and of optionally rectilinear longitudinal axis. The applicator elements may be straight, i.e. each may extend along a longitudinal axis that is rectilinear, e.g. perpendicular to the longitudinal axis of the support .
In a variant, each of the applicator elements may extend along a longitudinal axis that is curvilinear.
The applicator elements may present rounded free ends .
The applicator elements may form at least one row. The row may be oriented along the longitudinal axis X of the applicator member, or transversally thereto.
Within any one row, the applicator elements may be of different shapes and/or unevenly spaced.
The applicator member may comprise at least two rows of applicator elements, said rows being similar or different. The rows being different allow an applicator member having different application characteristics. The rows may be different, by virtue of the material of the applicator elements, their shape, length, thickness, disposition in the row, and/or implantation on the support, amongst other criteria.
Two rows of the same type may be situated opposite one to the other on the support.
In a variant the applicator member comprises several types of rows, the different types of rows optionally alternate around the longitudinal axis of the support at its periphery.
By way of example, in cross-section, the applicator elements present a longest dimension that is greater than or equal to 0.2 mm, better 0.5 mm.
The applicator elements may be pegs, in particular of cylindrical or frustoconical shape and of diameter at their bases lying in the range 0.2 mm to 1 mm. In a variant, the applicator elements are teeth, in particular having bases that are not circular. By way of example, the height of the applicator elements may lie in the range 1 mm to 12 mm, 2 mm to 6 mm, 3 mm to 12 mm, or 5 mm to 8 mm.
The applicator member may include at least one opening or cavity, e.g. between two rows of applicator elements. An opening or cavity makes it easier to hold a supply of composition on the applicator.
The applicator member may include at least one helical groove that extends over at least a fraction of the applicator member. The applicator member thus presents a helical thread that serves as an applicator element. The helical groove may extend from the visible proximal end of the applicator member to its distal end.
The applicator member may include a closed cavity, or it may include an opening that may be a through opening over all or part of its length.
The or each applicator element is preferably flocked, optionally over all of its height. Assembly
In the invention, a second container may be provided containing a second composition P' that is different from the first composition P, and, where appropriate, an applicator including an applicator member for applying the second composition to the eyelashes or the eyebrows. This makes it possible to coat the eyelashes completely with the second composition before depositing the fibers for actually lengthening the eyelashes.
The first and second containers may be secured together, at least when the associated applicator ( s ) is/are not being used, e.g. being secured together by means of an optionally-removable coupling member.
In a variant, the first and second containers are independent, with no means being provided to secure them together.
When the containers are secured together, the second container may be situated in alignment with the first, along its longitudinal axis; in a variant, the first and second containers are arranged side by side, optionally top to tail.
When one of the applicators remains secured to the container associated with the other applicator during its use, at least one of the containers may serve as a handle while the composition contained in the other container is being applied.
The first applicator, which is used to apply the composition containing the fibers or constituted by fibers, may be configured to close the first container. The same applies for the second applicator, which may be configured to close the second container.
The second composition P' may be of any type known to the person skilled in the art, for applying to the eyelashes and/or the eyebrows, in particular it may be liquid at ambient temperature or pasty or it may be in the form of gel.
The second composition P' may optionally include fibers, in particular free fibers. The fibers in the second composition may be identical or different from the fibers of the first composition. In exemplary embodiments, the second composition does not include fibers, said fibers being applied exclusively by means of the first composition.
The second composition may optionally be colored.
The second composition P' may include negative or positive charges, e.g. that can be combined with negative or positive charges of the fibers of the first composition P so as to promote the adhesion and/or the orientation of said fibers.
The second applicator may be of any usual type, arranged to apply a composition to the eyelashes or the eyebrows .
The second applicator may include an applicator member, e.g. a twisted-core brush, or it may be made by injection-molding a thermoplastic material. Preferably, if the second composition includes fibers, the second applicator is flocked, at least in part .
The same applicator may also be used to apply the compositions P and P'.
Where appropriate, after applying the composition P to the eyelashes coated with composition P', the composition P' is reapplied to the eyelashes and the fibers .
Wiper member (s)
Each of the first and/or second containers is preferably provided with a wiper member that defines a wiper orifice, e.g. a circular orifice, through which the corresponding applicator member passes when said applicator member is removed from the container, the diameter of the wiper orifice being matched to the diameter of the stem, and lying in the range 2.5 mm to 5.5 mm, for example.
The wiper orifice may be of cross-section other than circular, e.g. undulating or slotted.
When the wiper member of the first and/or second container includes one or more slots, said slots may be oriented radially or tangentially relative to the orifice.
The wiper member of the first and/or second container may include a block of foam that may be slotted .
The wiper member could also be as described in the following patents or patent applications:
US 2005/0028834; US 6 328 495; US 6 375 374;
US 2004/0258453; or US 2005/0175394.
The wiper member of the first and/or second container may be rigid or flexible, preferably being flexible, e.g. since it is made out of an elastomeric material . The body of the first and/or second applicator member may be flexible or rigid. The applicator member and the wiper member may be arranged in such a manner that the body of the applicator member deforms on passing through the wiper member. In a variant, the applicator member and the wiper member may be arranged in such a manner that the applicator member does not deform on passing through the wiper member. Kit
The invention also provides a packaging and applicator system (also known as a kit) for applying a makeup composition to the eyelashes or the eyebrows, the system comprising:
· a first container containing a first composition P including fibers or constituted by fibers, as defined above, and a first applicator including a flocked applicator member for depositing the composition on the eyelashes or the eyebrows; and
· a second container containing a second composition
P', and possibly a second applicator for depositing the second composition P' on the eyelashes or the eyebrows.
The two containers are made available to the consumer together, with their associated applicator ( s ) .
When the applicator ( s ) is/are not being used, the first and second containers may be secured together, e.g. by means of coupling means fitted on the containers.
The two containers may be made available to the user within a common package, together with their applicator ( s ) , and they may then be used independently after opening the package, the compositions being applied successively to the eyelashes, for example, as explained above . Method
Other exemplary embodiments of the invention provide a method of applying makeup to the eyelashes or the eyebrows, said method comprising applying, to the eyelashes, a composition P including fibers or constituted by fibers, in particular free fibers as mentioned above, by means of a flocked applicator member, preferably including at least one projecting applicator element .
The method of the invention is implemented with an applicator and a composition from an assembly or system as defined above.
The method advantageously includes a step prior to, or subsequent to, applying the composition containing the fibers, in which step a second composition is applied in a quantity that is sufficient to promote the adhesion of the fibers to the eyelashes.
By way of example, the second composition is a conventional mascara, a paste or a gel.
In a variant, the method:
• begins by taking fibers from the container containing the composition including the fibers; and
· continues by applying the fibers to the eyelashes by means of a flocked applicator; and then
• terminates by applying a second composition, in particular a gel, to the eyelashes that have already received the fibers, by means of any mascara brush.
In another variant, this other step constitutes a prior step, during which the other composition, also known as a base coat, is preferably spread in regular manner over all of the eyelashes, so as to coat them, and this then promotes the adhesion of the fibers. In this variant:
• a base composition is applied to the eyelashes, e.g. a gel that does not have free fibers;
• fibers are taken from a container containing the composition including the fibers, preferably free fibers; and
• by means of the flocked applicator, the fibers are applied to the eyelashes coated with base composition. By means of the flocked applicator, the user delicately deposits the fibers on the eyelashes that are already coated with base-coat composition, orientating said fibers all the way to the ends of the eyelashes. The base-coat composition may not have any fibers, as mentioned above.
After the fibers have been deposited on the eyelashes, a composition may be applied that tends to hold the fibers on the eyelashes, e.g. a gel, preferably the same gel or composition as the gel or composition used as the base composition. The same applicator may be used to apply the gel and the free fibers, or different applicators may be used.
In a variant, the second composition includes fibers, and the second composition is preferably applied with a flocked applicator.
The invention can be better understood on reading the following detailed description of non-limiting embodiments thereof, and on examining the accompanying drawings, in which:
• Figure 1 is a longitudinal section view showing an embodiment of a packaging and applicator assembly made in accordance with the invention;
• Figure 2 is a section view showing another embodiment of a packaging and applicator assembly of the invention ;
• Figure 3 shows an example of a suitable wiper member in isolation;
• Figures 4A and 4B are elevation views showing two examples of applicator elements;
• Figures 5A to 5G are side or perspective views of various applicator members;
• Figures 6A to 61 show various possible cross sections, amongst others, of applicator members;
· Figures 7 and 8 show other examples of assemblies of the invention; and
• Figure 9 shows an example of a fiber in isolation. The packaging and applicator assembly 10 shown in Figure 1 comprises: first and second containers 2, 2' containing respective first and second compositions P, P' for application to the eyelashes or the eyebrows; and associated first and second applicators 3, 3'. As shown, the applicators may be fastened in removable manner on the respective containers 2 and 2 ' .
The composition P of the invention is the first above-defined composition, and includes fibers or is constituted exclusively by fibers.
The applicator 3 includes an applicator member 8 that is covered in flocking 85, with projecting applicator elements 80, e.g. and as shown, in the form of annular ribs perpendicular to the axis X.
The flocking 85 may cover all of the visible surface of the applicator member 8 that is suitable for loading with composition.
In the embodiment shown, the flocking 85 comprises flocking that is uniform, such that the envelope surface defined by the free ends of the flocking bristles follows the outline of the underlying annular ribs.
By way of example, the body of the applicator member 8 is molded with the annular ribs, and constitutes their support .
The invention is not limited to a particular applicator member 8. Other examples of applicator members 8, shown in Figures 5A to 5G, are described in greater detail below.
Figures 4A and 4B show two examples of projecting applicator members 80.
In Figure 4A, the applicator element 80 presents a cylindrical peg shape.
In Figure 4B, the applicator element 80 is in the shape of a tooth having a wide base.
The general orientation of the bristles of the flocking 85 is preferably substantially orthogonal to the surface of the projecting applicator elements 80 and of the support 81.
The longitudinal axis R of the applicator element 80 may be locally perpendicular to the support or it may be oriented obliquely relative to the normal to the support, e.g. towards the left or the right when the applicator member is observed along its longitudinal axis.
Figure 9 shows an example of a fiber. When the fiber is curvilinear, its length L is measured along its longitudinal axis.
The applicator member 8 is connected to the distal end of a stem 5 that is connected at its other end to a handle 11 that also constitutes a closure member for closing the container 2 in leaktight manner. The container includes a threaded neck 14 on which the closure member 11 may be screwed. In a variant, the applicator may be fastened on the container in some other way. As shown, the neck 14 may receive a wiper member 20 that is fitted in the neck 14, for example.
Naturally, the invention is not limited to a particular wiper member 20 or to a particular method of fastening the wiper member 20 on the container, and said wiper member may be fastened in the neck 14 by any means, e.g. by force-fitting, snap-fastening, adhesive, heat- sealing, or over-molding. Where appropriate, the container may be made without a neck having a section that is constricted relative to the body of the container. The wiper member 20 may also be molded as a single part out of the same material as the body of the container 2.
The wiper member 20 may advantageously be as shown in Figure 3, and may include a wiper lip 20a that is undulating, having a radially-inner free edge defining an orifice 122, and including undulations 120 that extend around the orifice 122. The number of undulations 120 may lie in the range 3 to 12, for example. The wiper lip 20a may extend generally along a cone that converges towards the bottom of the container, and that has a generator line G forming an angle i_ with the axis X of the container. In a variant, the wiper lip 20a may extend generally perpendicularly to the axis X, or even along a cone that converges towards the outlet of the container.
Where appropriate, the wiper member 20 may also be adjustable, and this makes it possible, for example, to act on the quantity of fibers that are present on the applicator after it has been removed from the container.
The composition P' contained in the second container 2 ' is for application to the eyelashes or the eyebrows by means of the second applicator 3' that is arranged so as to be fastened in removable manner on the second container 2 ' .
The composition P' advantageously contributes to holding the fibers of the first composition on the eyelashes, and it is applied to said eyelashes before the first composition P, and possibly also after.
The second applicator 3 ' includes a stem 5 ' of longitudinal axis X' that is provided at one end with an applicator element 8'. By way of example, the applicator element 8' may be a twisted-core brush, as shown. At its other end, the stem 5 is connected to a closure member 11' for closing the container 2' and constituting a handle of the applicator 3'. A wiper member 20' is fastened in the neck 14' of the container 2'.
The applicator member 8' of the second applicator 3' is not limited to a twisted-core brush, and in particular an applicator such as a comb or an injection-molded brush may be used to apply the composition P' to the eyelashes or the eyebrows .
In another variant that is not shown, the composition P' includes fibers, and the applicator member of the second applicator is flocked. In the embodiment in Figure 1, the two containers 2 and 2 ' are secured to each other by means of a coupling member 100 that may be removable, as in the variant shown, so as to make it possible to remove one of the containers and its applicator in order to replace it, for example .
The invention is not limited to the particular containers 2 and 2 ' , and said containers may be of any shape .
In the variant shown in Figure 2, the assembly 10 includes a double closure member 11 that serves both to close the container 2 containing the composition P including the fibers, and the container 2' containing the auxiliary composition P'. The closure member thus acts as a coupling member 100 between the containers.
The containers 2 and 2 ' are arranged in alignment with each other along the axis X.
In order to use the applicator 3', the user may leave the container 2 secured to the closure member 11, and thus use the container 2 as a handle. Similarly, the user may then leave the container 2 ' secured to the closure member 11, and use it as a handle in order to use the applicator 3.
In a variant that is not shown, the containers are still in alignment with each other, but the respective closure members are independent.
In another variant that is not shown, the containers are situated in alignment with each other, one of the containers being secured to the closure member of the other container.
There exist still other possibilities for securing the devices together, at least when not in use.
By way of example, the containers and the corresponding applicators are housed in a common housing when not in use.
In the embodiment shown in Figure 2, the applicator member 8 includes a molded support 81 that is formed of two branches 81a and 81b, each covered in respective flocking 85 and defining between them an opening 83 of elongate shape. Each of the branches 81a and 81b supports two rows of projecting applicator elements 80 in the form of regularly spaced apart pegs, e.g. arranged in a staggered configuration, distributed over at least a main face 180 of the support 81, which main face is observed in face view in Figure 2.
In the variant shown in Figure 8, the main face 180 does not have applicator elements 80 in the proximity of the axial ends 8a and 8b of the applicator member 8.
In other variants, and as shown in Figures 5A to 5C, the applicator member 8 comprises a body made of foam or of some other material, preferably an elastically- deformable and compressible material, and suitable for loading with the composition for application.
Figure 5A shows an applicator member 8 that is completely flocked, that is of shape that is circularly cylindrical over the major fraction of its length, and that presents a distal end 8a in the shape of a point that makes it easy to deposit fibers on the smallest eyelashes .
The applicator member 8 shown in Figure 5B comprises: end portions 8a and 8b that are frustoconical , making it possible to pass more easily through the wiper orifice; and a central portion having a cross-section that progressively narrows from the end portions 8a and 8b towards a middle zone. In elevation, the applicator member 8 thus presents a shape that is outwardly bi- concave, making it easier for a supply of composition to form on the applicator member and for fibers to accumulate .
The applicator member 8 may be circularly symmetrical, as shown in Figures 5A and 5B, or it may be of shape that is flat, as shown in Figure 5C.
In a variant, the applicator member 8 includes a support 81 that includes two branches 81a, 81b that surround a through opening 83, as shown in Figure 5D. In this example, the branch 81a carries a row 88 of applicator elements 80 that are in the form of teeth, e.g. said teeth projecting from a main face 180 of the support 81, as shown. Each of the applicator elements 80 may extend generally parallel to the normal N to the plane of the opening 83. As shown, the applicator member may also include a row of applicator elements 80 on the face 181 opposite the face 180. The branch 81b does not include applicator elements in the example shown. The user may choose to deposit more or less composition on the eyelashes depending on which branch 81a or 81b of the applicator member that is used. The inside edge 183 of the opening 83 and the opposite, outside faces 186 of the branches 81a and 81b may be flocked while not having any applicator elements. The side faces 186 may be generally plane, or they may present an outwardly-convex rounded profile, as shown.
Along the longitudinal axis X, the total length I occupied by a row of applicator elements 80 is greater than or equal to 20 mm, for example.
It would not be beyond the ambit of the invention for the applicator member to include applicator elements that are distributed in a plurality of rows and/or that are present on both branches, or elsewhere on the support, e.g. on the inside edge of the opening 83 and/or at the periphery of the support. Optionally the plurality of rows presents rows differing by one or several characteristics such as the material of the applicator elements, their shape, length, thickness, disposition in the row, and/or implantation on the support.
In a variant that is not shown, the two branches of the support form a cavity that is not a through cavity, opening out in one of the faces of the support, or two cavities that open out in two respective opposite faces of the support. In Figure 5E, the applicator elements 80 are in the form of ribs that are oriented obliquely relative to the longitudinal axis X. In a variant, the applicator member 8 presents a helical thread.
The applicator in Figure 5F includes applicator elements 80 that are arranged in a grid pattern.
The applicator in Figure 5G includes a succession of constrictions that are axially spaced apart. The applicator may be of cross-section that is triangular, as shown in Figure 6D.
Over at least a fraction of its visible length, the body of the applicator member 8, with or without the applicator elements, may present a cross-section that is: circular, as shown in Figure 6A; oval, as shown in Figure 6B; polygonal, e.g. in the shape of a lozenge, a triangle, a square, or an octagon, as shown in Figures 6C to 6F respectively; this list not being limiting.
The support 80 may constitute a core of the applicator member 8 as illustrated figures 6G-6K.
Figures 6G and 6H show cross-sectional views of applicator members 8 including a square support 81 and projecting applicator elements 80 extending away from the support substantially in continuation of different sides 81a of the support 81 and in different directions from one another.
Figure 6J and 6K illustrate embodiments comprising supports 81 having pentagonal and respectively hexagonal cross sections.
The projecting applicator elements 80, in the form of teeth, of rows 88 of figure 6K are optionally different, being of two kinds that alternate.
The sides of the support may be planar or non- planar, such as convex or concave for example. The rows of projection elements 80 are disposed substantially in the continuation of the sides 81a of the support 81. The support may also have a non-polygonal cross section, for example a cross section of elliptical shape, as illustrated in Figure 61.
Figure 61 shows two rows 88 of projecting applicator elements 80 disposed on the support 81 such that they extend away from the support. An axis of the projection elements is in a direction substantially at a tangent to the support where the projecting applicator elements 80 each meet the support 81. The rows 88 of projecting applicator elements in Figure 61 are disposed on the support substantially diametrically opposite from one another .
In particular, the applicator member may present any number of longitudinal faces, which faces optionally carry one or more applicator elements and that are optionally flocked.
In Figure 7, the containers 2 and 2' are independent, but may be made available to the user within a common package.
Figure 8 shows a single container 2 generally in the shape of a ball that is filled with a single composition P containing the fibers .
The generally non-cylindrical shape of the container 2 is particularly advantageous for benefiting from a free space in the container, above the composition, and this makes it possible to avoid compressing the fibers, and makes it easier to homogenize the composition before application, e.g. by shaking the container.
The container containing the composition filled with fibers and the flocked applicator may be made available to the user as a complementary device for lengthening keratinous fibers, the user being able to associate the mascara of choice with the use of the composition of the invention containing the fibers, which composition is applied with the flocked applicator.
The expression "comprising a" is synonymous with "comprising at least one", and "lying in the range" should be understood as including the limits of the range .
The invention is not limited to the containers nor to the applicators shown, and the characteristics of the above-described embodiments may be combined together within variants that are not shown.
In the applicators shown, the stem presents a longitudinal axis that coincides with the longitudinal axis of the applicator member. It would not be beyond the ambit of the invention for the applicator member to present a longitudinal axis that is rectilinear or curvilinear, forming an angle with the longitudinal axis of the stem.
