Abstract

An applicator for applying a substance to a fringe of eyelashes or eyebrows, may include a stem, a support associated with the stem and extending along a longitudinal axis, and a plurality of applicator elements extending from the support substantially transversely relative to the longitudinal axis. The applicator elements may extend over a distance along the longitudinal axis of the support such that when the longitudinal axis extends substantially tangentially to the fringe, the applicator elements can at most come into contact simultaneously with no more than one-fourth of the eyelashes or the eyebrows of the fringe.

Description

This application claims benefit of U.S. Provisional Application No. 60/628,533, filed Nov. 18, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. 04 52397, filed Oct. 21, 2004, the contents of which are also incorporated herein by reference.
The present invention relates to an applicator for applying a substance (e.g., mascara) to the eyelashes or the eyebrows.
Various applicators are proposed in the following patent applications: EP 1 070465, EP 1 070466, EP 1 070467, EP 1 070468, EP 1 115503, EP 1 115304, EP 1 115 305, EP 1 157 629, EP 1 157 632, EP 1 169 941, and FR 2 810 861, the contents of each of which are incorporated in the present application by reference in their entirety.
Patent application FR 2 564 712 discloses a cosmetic applicator comprising an elongate handle provided with a plurality of bristles or teeth molded integrally therewith and extending axially from one of the ends of the handle.
There may exist a need to benefit from an applicator enabling novel makeup effects to be obtained on the eyelashes and/or the eyebrows, for example, enabling substance to be deposited only on a single patch of eyelashes or eyebrows.
Using an applicator of the paintbrush type for this kind of application may not be very satisfactory since if the brush is not sufficiently wiped, then it may retain a drop of substance at its tip which may create a blob on the eyelashes.
If the brush is wiped too much, then the amount of substance that remains may turn out to be insufficient.
The use of a flocked applicator may make it possible to obtain a good quantity of substance but it may be difficult, if so desired, to separate eyelashes that have become stuck together by the substance.
Although the present invention may obviate one or more of the above-mentioned needs, it should be understood that some aspects of the invention might not necessarily obviate one or more of those needs.
In the following description, certain aspects and embodiments will become evident. It should be understood that the invention, in its broadest sense, could be practiced without having one or more features of these aspects and embodiments. It should be understood that these aspects and embodiments are merely exemplary.
One exemplary aspect may relate to an applicator for applying a substance to a fringe of eyelashes or eyebrows. The applicator may include a stem, a support associated with the stem and extending along a longitudinal axis, and a plurality of applicator elements. The plurality of applicator elements may include only two applicator elements, may be disposed on the support, and may extend substantially transversely to the longitudinal axis of the support.
In another aspect, the applicator elements may extend over a distance along the longitudinal axis of the support such that when the longitudinal axis extends substantially tangentially to the fringe, the applicator elements can at most come into contact simultaneously with no more than a fraction of the eyelashes or the eyebrows of the fringe, for example, one-fourth, one-fifth, or one-sixth of the eyelashes or the eyebrows of the fringe.
In a further aspect, a made-up patch of eyelashes or eyebrows may correspond, for example, to no more than a fraction of the length of the fringe, for example, one-fourth, one-fifth, or one-sixth of the length of the fringe.
In yet another aspect, the applicator elements may comprise teeth and/or bristles.
In yet a further aspect, the applicator may enable the eyelashes to be covered suitably, for example, while exerting a combing action.
In still another aspect, the applicator elements may extend on the support over a distance that is short enough to enable one or a few patches of eyelashes or eyebrows to be made up, for example, so as to enable somewhat unique makeup effects to be obtained.
In a still further aspect, it may be possible to create colored patches or stripes in the eyelashes. For example, it may be possible to make up the eyelashes in a given fringe using at least two different colors.
As used herein, the word “fringe” refers to the eyelashes of the top eyelid or those of the bottom eyelid, going from the inner corner to the outer corner of the eyelid, or the eyebrow arch over one or the other of a user's eyes.
In another aspect, the applicator elements may extend along the support over any suitable distance, for example, in the range of about 0.1 centimeters (cm) to 1 cm, less than or equal to 8 millimeters (mm), less than or equal to 7 mm, less than or equal to 6 mm, lying in the range of 2 mm to 5 mm, or in the range of 2 mm to 3 mm.
In a further aspect, an applicator for applying a substance on the eyelashes or the eyebrows may include a stem, a support associated with the stem and extending along a longitudinal axis, and at least one row of applicator elements The applicator elements may constitute teeth. The applicator elements of the at least one row may each extend substantially transversely to the longitudinal axis of the support and may present free ends at distances from the longitudinal axis that may vary in a non-monotonic manner between the two opposite end applicator elements of the row.
As used herein, the term “varying in non-monotonic manner” should be understood as meaning that the line interconnecting the free ends of the applicator elements has a distance from the longitudinal axis of the support that passes through at least one extremum, e.g., a maximum distance of a free end of a longest applicator element from the longitudinal axis of the support.
The presence of a maximum in the row of applicator elements may enable applicator elements to penetrate progressively further into the eyelashes, for example, to make it easier to apply makeup to a patch.
In another aspect, the number of applicator elements in the row, in particular the number of teeth, may be any suitable number, for example, in the range of 3 to 9, in the range of 3 to 8, and/or in the range of 3 to 7.
In a further aspect, the support and the applicator elements may be made as a single piece, for example, by molding or by machining. In a variant, the applicator elements may be separate from the support and may be fitted to the support.
In yet another aspect, the support and the stem may be made as a single piece, for example, by molding, or in a variant the support may be separate from the stem and may be fitted to the stem. Under such circumstances, the support may include an endpiece arranged to engage on or within a housing of the stem, or the stem may include an endpiece arranged to engage on or within a housing of the support.
In a yet further aspect, the stem may extend along a longitudinal axis that is different from the longitudinal axis of the support. Under such circumstances, the longitudinal axis of the stem and the longitudinal axis of the support, for example, the respective portions thereof carrying the applicator element, may form between them any suitable angle. For example, the angle may lie in the range of 5° to 45°, in the range of 15° to 25°, or equal to about 20°. Such a configuration may make the applicator more comfortable to handle while applying substance to the eyelashes. The longitudinal axis of the support may be curvilinear or rectilinear.
In still another aspect, the stem may extend along a longitudinal axis that substantially coincides with the longitudinal axis of the support.
In a still further aspect, the applicator and/or the support may be made at least in part out of a material that is flexible or rigid, for example, at least in part out of a thermoplastic, an elastomer, or a thermoplastic elastomer material. The material may be molded. The applicator may be made at least in part out of any material or combination of materials, for example, wood and/or metal. The material may be machined.
In another aspect, the support may be made of an elastically deformable material. The elastically deformable material may enable one side of the support to be wiped preferentially.
In a further aspect, the stem and the support may be made out of different materials.
In yet another aspect, when the applicator is observed from the side, a line interconnecting the free ends of the applicator element may present a distance from the longitudinal axis of the support that passes through at least one extremum, for example, a maximum distance from the longitudinal axis of the support, which may enable the applicator to penetrate more progressively further into the eyelashes.
In a further aspect, any line defined herein or any portion of any line defined herein may have any suitable shape, for example, a triangular shape, a rounded shape, a circular shape, or a bullet-like shape.
In still another aspect, any line disclosed herein may include a profile. The profile may include a maximum distance and a minimum distance, for example, relative to the longitudinal axis of the support. A first straight line may interconnect free ends of a longest applicator element associated with the maximum distance from the longitudinal axis of the support and a shortest applicator element associated with a minimum distance from the longitudinal axis of the support closest to the longest applicator element. A second straight line may include the normal to the longitudinal axis of the support. The normal may pass through the free end of the longest applicator element. The angle formed between the first line and the second line may lie in the range of 25° to about 60°, in the range of 25° to 50°, in the range of 25° to 45°, in the range of 30° to 45°, or be equal to about 43°.
In a still further aspect, the distance of any line defined herein, as measured from the longitudinal axis of the support, may pass through two or more extremum.
In another aspect, the applicator elements may be disposed in a single row or in at least two rows. When there are at least two rows, the applicator elements in a first row and those in a second row may extend in different directions. Alternatively, the applicator elements in the first row and those in the second row may extend in substantially parallel directions. The two rows may be disposed substantially opposite to each other relative to the support.

MORE DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
The device 1 shown in FIGS. 1 to 4 may include a receptacle 2 containing a supply of a cosmetic P, for example, mascara, and may include an applicator 3 having a stem 4 extending along a longitudinal axis X.
The stem 4 may be provided at one end with a support 5 having a plurality of applicator elements 6, and may at its opposite end be configured to be connected to a closure cap 7 for closing the receptacle 2. The stem 4 also may constitute a handle element.
The closure cap 7 may have an inside thread (not visible), for example, for screwing the closure cap 7 onto the neck 11 of the receptacle 2. The neck 11 may have an outside thread. However, the closure cap 7 may be connected to the neck 11 in any suitable manner.
The receptacle 2 may include a wiper member 8, for example, disposed in the neck 11. The wiper member 8 may have a wiper lip 9 arranged to wipe the stem 4 and/or the support 5 carrying the applicator elements 6.
The wiper member 8 may be deformable, for example, when the applicator elements 6 passes through the wiper member 8.
The wiper member 8 may be made by injection molding and may be made of polyolefin. However, the wiper member 8 may be made using any suitable method and out of any suitable material.
The receptacle 2 may be configured to be closed in a leaktight manner when not in use, for example, by screwing the closure cap 7 onto the neck 11.
The applicator 3 may include a comb and the applicator elements 6 may constitute teeth. The support 5 may extend along a longitudinal axis Y that forms a non-zero angle α relative to the longitudinal axis X of the stem 4, for example, as can be seen in FIG. 3. Angle α may lie in the range of 5° to 45°.
The applicator elements 6 may be disposed in a row 10. The applicator elements 6 may include any number of applicator elements 6, for example, six (6) applicator elements.
The applicator elements 6 may be situated on the support 5 in any suitable configuration(s).
The row 10 may have a first series of teeth 6 a and a second series of teeth 6 b. The first series of teeth 6 a and the second series of teeth 6 b may be disposed in any suitable configuration. The first series of teeth 6 a and the second series of teeth 6 b may be respectively situated on opposites sides of a separation plane S. The separation plane S may be a middle plane of symmetry of the comb, may be parallel to the plane in which FIG. 3 is disposed, and may constitute a join plane for molding the comb.
The teeth 6 a and 6 b may extend in alternation on opposite sides of a common core 15 of the support 5. Support 5 may act as a skeleton with the bottom end of the teeth 6 a and 6 b being connected thereto. The teeth 6 a and 6 b may be connected to the support 5 in any suitable manner.
The support 5 may have any suitable configuration. The support 5 may have a rounded nose 17 at its front, for example, to make it easier to place the support 5 into the receptacle 2.
At its rear end, the support 5 may have a bulge 18, for example, that may make it easier to pass the support 5 through the wiper member 8 when the support 5 is being extracted from the receptacle 2.
Each applicator element 6 may have a top portion 20 terminating in a free end 30, and may have a bottom portion 22 extending from the core 15 of the support 5.
The applicator elements 6 may extend substantially perpendicular to the axis Y of the support 5.
The free ends 30 of the applicator elements may be situated at a distance from the longitudinal axis Y that varies in non-monotonic, continuous manner between the applicator elements disposed on the end of the row 10, e.g., from the left end of the applicator 3 to the right end of the applicator 3 in FIG. 3.
In the example shown in FIG. 3, when the applicator is observed from its side, the line L interconnecting the free ends 30 may present, in a direction perpendicular to the longitudinal axis of the stem 4 and to the above-mentioned separation plane S, any suitable shape. The suitable shape may be a substantially triangular shape. For example, the line L may include two rectilinear segments forming between them any suitable angle, for example, substantially equal to 90°.
Teeth 6 a and 6 b may have any suitable length, which may be the same lengths or different lengths relative to each other. For example, the longest teeth 6 a and 6 b in each set of applicator elements 6 may have substantially the same length.
The straight line D₁passing through the free end of the shortest applicator element starting from the distal end of the applicator and the free end of the longest applicator element that is closer to the shortest element may coincide with the first rectilinear segment of the line L.
The angle al formed between the line D₁and the perpendicular line N₁to the axis Y passing through the free end of the above-mentioned longest applicator element may form any angle, for example, in the range of 25° to 60°, or substantially equal to about 43°.
The line D₂passing through the shortest applicator element starting from the proximal end of the support 5 and the longest applicator element that is closer to said shortest element may coincide with the second rectilinear segment of the line L.
The angle α₂formed between the line D₂and the perpendicular line N₂to the axis Y passing through the free end of this longest applicator element may lie in the same range of values as the angle α₁, for example, angle α₂may be substantially equal to α₁. The angle at the apex between the segments of the line L may be less than or equal to 120°, for example, less than or equal to 90°.
The applicator elements 6 may extend on the support 5 over any suitable distance, for example, a relatively short distance d. Distance d may lie in the range of about 0.1 cm and about 1 cm. For example, as shown in FIG. 2, using the applicator 3, it may be possible to apply a substance (e.g., makeup) to a single patch of eyelashes at a time, without touching all of the eyelashes on the eyelid. For example, the applicator elements 6 may be configured, at most, to come into contact simultaneously with no more than one-fourth of the eyelashes of the top eyelid.
The substance P may be applied to eyelashes or eyebrows that have already have had a substance (e.g., makeup) applied thereto.
The substance P may include an suitable formulation, for example, a reversible polymer formulation, e.g., a vinyl formulation. The substance P may be configured to withstand cold water and/or dissolve in hot water.
The substance P may constitute a mascara having any suitable color, for example, black and/or colored. The formulation of the substance P may make it compatible with an underlying mascara, for example, so that when the substance P is applied to form a patch on eyelashes that have already been made up, it may not remove the mascara that is already present on the eyelashes.
The support 5 and the applicator elements 6 may be made integrally as a single piece. However, the support 5 and the applicator elements 6 may also be made as separate pieces. The support 5 and the applicator elements 6 may be made out of a plastic material, for example, via molding. However, the support 5 and the applicator elements 6 may be made using any suitable method and out of any suitable material. The support 5 may be fitted to the stem 4 in any suitable manner, for example, the manner that is described in greater detail below with reference to FIGS. 10 and 11.
The top portions 20 of two consecutive applicator elements 6 may leave between them a notch 21 extending substantially down to the core 15, for example, when the comb is observed from the side as shown in FIG. 3. The notches 21 may make it easier to take hold of the eyelashes, e.g., for the purposes of separating them, combing them, and/or smoothing out the substance that has been deposited on the surface of the eyelashes.
It will be understood that by varying the lengths of the applicator elements and/or the gaps between them, it may easier to control the total quantity of substance picked up by the applicator.
The distance between the tips of two successive applicator elements 6 a or 6 b, for example, situated on the same side of the separation plane, may be any suitable distance. For example, the distance may be considerably greater than the width of an applicator element as measured at half height of the applicator 3, e.g., in a direction parallel to the axis Y of the support 5.
When the applicator 3 is observed from the side, each applicator element 6 a may extend over substantially half the distance between two adjacent applicator elements 6 b, and vice versa.
The top portions 20 of the applicator elements 6 may all point in substantially the same direction.
The bottom portions 22 of two successive applicator elements, for example, situated on the same side of the core 15, may have any suitable configuration. For example, the bottom portions 22 of two successive applicator elements may co-operate with each other and/or with the core 15 to form a cavity 23 that may hold a supply of substance.
The spacing between the applicator elements 6 a or 6 b may be any suitable spacing. For example, the spacing may be relatively large, which may increase the quantity of substance that the applicator can pick up without the applicator losing the ability to take hold of the eyelashes. This may be made possible by the applicator elements 6 being offset from each other and/or by the fact that the notches 21 formed by the top portion 20 of the applicator elements 6 may remain sufficiently narrow.
The applicator elements 6 may present numerous configurations without going beyond the ambit of the present invention. For example, the top portions may be oriented in different directions.
The applicator elements 6 may be arranged on the support in a various configurations.
FIGS. 5 and 6 show another example of an applicator comprising a plurality of teeth 6, e.g., extending along a row 10. For example, the plurality of teeth may include seven teeth, however, any suitable number of teeth 6 may be used. As can be seen in FIG. 6, the bases 22 of teeth 6 may be in alignment and/or the top portions 20 of two consecutive teeth 6 a and 6 b may diverge.
FIG. 7 shows that it is may be possible to make the stem 4 with a longitudinal axis X that coincides with the longitudinal axis Y of the support 5.
