Description

FIELD OF THE INVENTION

The invention relates to the field of packaging cosmetic or make-up products typically in powder form, and relates more particularly to means of applying these products, as well as to the field of cases that include these cosmetic products.

PRIOR ART

Powders intended for make-up are generally packaged in receptacles called “cases”.

These cases typically include as a means of applying said powder, a powder puff.

Furthermore, people who apply make up at home also often have available make-up brushes, typically in the shape of an artist's paintbrush.

Problems Posed

The problems posed by the means of applying powder according to the prior art take numerous forms:

on the one hand, people using powder wish to be able to have available at all times, even outside the bathroom, different application means such as brushes,

on the other hand, the traditional powder puff has some drawbacks, both in terms of hands getting dirty, and of its single texture and, consequently the limited possibilities it gives of obtaining different effects or looks, on the face,

furthermore, as far as the brushes themselves are concerned, on the one hand, they typically constitute an autonomous accessory independent of the case, and on the other hand, a number of brushes are needed if different looks or effects are to be obtained on the face,

moreover, powder puffs or brushes are typically meant to be applied flat, whereas the face, particularly in the cheekbone area, has a rather angular contour,

lastly, in the make-up field particularly, it is important for the commercial product offer to be renewed on a regular basis, since novelty often takes precedence over tradition in the mind of the purchaser.

DESCRIPTION OF THE INVENTION

According to the invention, the brush intended to apply, typically onto a support, typically the face, at least one powdered product, typically a compacted make-up powder and/or a blusher, includes a typically rigid mount M, acting as a means of gripping said brush manually, and a means of applying said product integral with said mount including a typically flexible application material, and is characterised in that:

a) said mount M acts as a support to at least two different application means, typically two different tufts T of said application material, with each application means or different tuft T _iincluding a foot or base B_iso as to anchor each application means to said mount M, and a sheaf F_iincluding or constituted by said typically flexible application material, each sheaf F_iemerging from a different portion of said mount M along a different surface S_iof said mount, each sheaf F_idefining a lateral envelope E_ilimited at its end by an application surface A_i, so as typically to allow at least two different applications of said powder onto said support, and in that:

b) said mount forms a typically two-dimensional object, of larger dimension D typically less than 50 mm, and of thickness E typically less than 0.3 D, in such a way that said brush is able to be placed typically in a make-up case.

This combination of means allows the problems posed to be resolved.

Indeed, brushes according to the invention are brushes adapted to cases containing said powder. These brushes include a mount constituting manual gripping means and a support for at least the two different application means, such that by playing on the shape and/or the nature of these application means, as will be shown particularly in the figures, it is thereby possible to resolve the problems posed.

DESCRIPTION OF THE FIGURES

FIGS. 1[0017] a and 1 b are three-dimensional views of brushes (1) with only the mount (2) being show for reasons of clarity.
These show a perspective view of said mount ([0018] 2) typically two-dimensional in form in a plane P, a plane Ps, Ps′ perpendicular to the plane P sharing said mount typically in two parts, each including a different surface S_i(or S₁and S₂in the case shown in FIGS. 1a and 1 b), being the surface of said mount from which said application means emerges.

DETAILED DESCRIPTION OF THE INVENTION

According to the invention, said mount M ([0043] 2) is able to form an object of maximum thickness E typically less than 10 mm, each sheaf F_ihaving a length L_Ffrom 0.5.D to 1.5.D, said length LF being the distance between said mount M and said application surface A_i. Thus, said brush forms a typically flat object able to be placed in a case, the tufts being able to be compressed so as to have a thickness at most equal to that of the mount.
See for example FIG. 1[0044] b.
As shown in most of the figures, said mount M ([0045] 2) may include two different tufts T₁and T₂, each tuft T₁(3, 4) and T₂(3′, 4′) forming a sheaf F₁(31, 41) and F₂(31′, 41′) respectively emerging from said mount M along two different surfaces S₁(20) and S₂(20′) respectively.
These different surfaces correspond to portions of the envelope surface of said mount, from which the tufts T[0046] ₁(3, 4) and T₂(3′, 4′) emerge. They have been shown in FIGS. 1a and 1 b in hatched lines, the tufts not having been shown in these figures.
As shown in FIGS. 1[0047] a, 1 b, 2 d, 5 b and 7 a, said different surfaces S₁(20) and S₂(20′) may be longitudinal, typically rectangular or oblong surfaces, of length or larger dimension L typically from 5 to 20 mm, and of width or smaller dimension 1 from 1 to 5 mm, with L/l from 2 to 10, so as to form two typically longitudinal sheaves F₁and F₂typically forming two flexible curtains.
However, as shown in FIGS. 3[0048] a to 3 c, said surfaces S₁(20) and S₂(20′) may typically be circular, or semi-circular surfaces, of diameter d typically from 2 to 10 mm.
As shown in FIGS. 7[0049] a and 7 b, said different surfaces S₁(20) and S₂(20′) may be contiguous, on one side or at a common point.
However, as shown in FIGS. 2[0050] a and 2 c, said different surfaces S₁(20) and S₂(20′) may be spaced apart by a distance e, measured from edge to edge, or by a distance e′, measured from centre to centre, said distance e typically being less than 0.4.D, and e′ typically from 0.2.D to 0.8.D.
As shown in FIGS. 2[0051] a and 2 b, and in FIGS. 3a and 3 b, said sheaves F_i(31, 31′, 41, 41′) may have a maximum angle of aperture of α>0 and possibly a minimum angle of aperture α′>0, with α′<α. These angles are taken relative to the median plane of the sheaves. It is possible to have an angle α, typically from 15° to 45° and an angle α′ typically from 5° to 30°.
As shown in FIGS. 2[0052] a and 2 b, said surfaces S₁(20) and S₂(20′) may be non-contiguous and be spaced apart by a distance e such that said corresponding application surfaces A₁(32, 42) and A₂(32′, 42′) are contiguous, given said angle of aperture α, said distances e or e′ and said length L_F.
The application surfaces may be contiguous to a more or less significant degree, namely just contiguous, as shown in FIG. 5[0053] c, slightly contiguous as shown in FIG. 3a, and largely contiguous as shown in FIG. 4a.
But, as shown for example in FIG. 4[0054] b, said surfaces S₁(20) and S₂(20′) may be non-contiguous and be spaced apart by a distance e such that said corresponding application surfaces A₁(32, 42) and A₂(32′, 42′) are non-contiguous, given said angle of aperture α, said distances e or e′ and said length L_F.
According to a form of mount ([0055] 2) shown in FIGS. 1a and 2 a, said surfaces S₁(20) and S₂(20′) may be in one and the same plane P′ which is typically perpendicular to said medium plane P.
According to a form of mount ([0056] 2) shown in FIGS. 1, 4b and 5 a, said surfaces S₁(20) and S₂(20′) may be located in different planes P′₁and P′₂respectively, typically perpendicular to said medium plane P, and forming between them an angle β, typically equal to 150°±25°, in such a way that, with said corresponding application surfaces A₁(32, 42) and A₂(32′, 42′) forming between them an angle typically close to said angle β, said application surfaces may conform in shape to the outlines and contours of the face, typically the cheekbones of the face.
According to the invention, at least one of the planes P′[0057] ₁and P′₂is able not to be perpendicular to said medium plane P. Indeed, it is not necessary for the planes P′₁and P′₂which include the surfaces S₁(20) and S₂(20′) to be perpendicular to the medium plane P of the mount (2). These planes may indeed form with said plane P an angle slightly different from 90°.
As shown in FIGS. 1[0058] a, 1 b and 2 a, said different tufts T₁(3, 4) and T₂(3′, 4′) may be geometrically symmetrical relative to a plane of symmetry Ps perpendicular to said plane P.
However, given the nature of the invention, it is possible to have tufts that are dissymmetrical by their shape and/or their volume. [0059]
As shown diagrammatically and partially in FIG. 2[0060] a, said different tufts T₁(3, 4) and T₂(3′, 4′) may be tufts of hair (4, 4′). These tufts of hair may be constituted by hairs PL of the same nature or texture.
However, said different tufts T[0061] ₁(3, 4) and T₂(3′, 4′) may be tufts of hairs (4, 4′) constituted by hairs of different nature or texture PL1 and PL2, so as to be able to form two applications, that are different by texture or grain, of one and the same product or of two products.
According to the invention, said different tufts T[0062] ₁(3, 4) and T₂(3′, 4′) may be formed by one and the same fibrous or alveolar material able to provide a transfer of said product, or by two different fibrous or alveolar materials able to provide a transfer of said product.
As shown in FIG. 1[0063] b, said application surfaces A₁(32, 42) and A₂(32′, 42′) may project themselves orthogonally over a plane Pp perpendicular to said plane Ps typically according to a rectangle S_Aof length L_Aand of width l_A, each application surface (32, 32′, 42, 42′) projecting itself typically along a length L_A/2, in the case of contiguous application surfaces A₁and A₂, with L_Atypically less than D and with l_Atypically less than 3.E.
According to one form of the invention, and as shown in FIGS. 2[0064] a to 2 c, 3 a, 3 c, 4 b, 5 a, 6, said mount (2) may include as many different cavities Ci (24, 24′) as tufts T_i, said foot or base B_iof each tuft T_ibeing anchored into said cavity C_i.
According to another form of the invention shown in FIG. 4[0065] a, said foot or base B_iof each tuft T_imay be anchored, typically by bonding, to said surface S_iof said mount (2), the mount (2) not including any cavities.
It is also possible to anchor the tufts to the mount by snapping them on. [0066]
Another subject of the invention is constituted by a case ([0067] 5) for dispensing product typically in the form of compacted powder (9) including a brush (1) according to the invention, said brush (1) forming a means of application of said product and being of dimensions adapted to those of said case, so as to be able to be placed in said closed case (5) between a bottom (6) of said case fitted with at least one pot (8) containing said compacted powder (9) and a lid (7) of said case typically including a mirror (70).
Engagement between the typically two-dimensional brush ([0068] 1) and the case (5) has been shown in FIG. 4b.
As shown in FIGS. 6 and 8[0069] a, this case (5) may include a single pot (8) containing a single compacted product PC and in which the compacted product has a contact surface S_Cwith a dimension or width L_Csuch that the ratio L_A/L_Cis close to 1 and typically between 0.7 and 1.1, so as to apply the same product using two different tufts T₁and T₂as shown for example in FIG. 6.
But, as shown for example in FIG. 8[0070] a, said compacted product (9) includes two different compacted products PC₁and PC₂typically forming a single block of compacted powder, and separated along a typically straight line of demarcation LD, so that, said brush being applied against said compacted product and said central common area ZC of said tufts along said line of demarcation LD, it is thus possible to take up simultaneously two different products typically in a single movement.
Each of these two different compacted products PC[0071] ₁and PC₂may form a block placed in one and the same pot, as shown in FIGS. 8b to 8 d, or in two pots side by side along a line of demarcation LD′, as shown in FIG. 5c, in such a way that the two blocks are typically at the most 2 mm apart.
As shown in FIG. 8[0072] b or in FIG. 6, said compacted products PC1 and PC2 may form a total contact surface S_Cwith an average dimension L_C, taken perpendicularly to said line of demarcation LD or LD′ comparable to a straight portion, such that the ratio L_A/L_Cis close to 1 and typically between 0.7 and 1.1, so as to have a contact surface adapted to said brush (1).
As shown in FIGS. 8[0073] c and 8 d, said contact surface S_Cmay form an angle γ typically close to 180°±40° or possibly 360°-β, in such a way that said brush, according to the geometric shape of said application surface A₁or A₂is able to take up powder from said two products uniformly by passing said sheaves of hair F₁and F₂over said contact surface S_C.
Exemplary Embodiments [0074]
The figures constitute exemplary embodiments. [0075]
Brushes ([0076] 1) were manufactured with mounts (2) as in FIGS. 1a to 2 d for rectangular cases of 60 mm×80 mm.
Brushes ([0077] 1) were manufactured with mounts (2) as in FIGS. 3a to 6 for round cases of 60 mm diameter as shown in FIG. 8a.
The mounts ([0078] 2) were formed by moulding.
Different types of compressed powder blocks were formed as shown in FIGS. 5[0079] c, 6, 8 a to 8 d.
The large dimension D of the mount ([0080] 2) was taken as equal to 40 mm, and the thickness E as equal to 8 mm.
Tufts of hair were formed that corresponded substantially to what is shown in the figures. These tufts were anchored to the mounts by anchoring the foot of the tuft into a cavity in the mount, or by bonding the foot onto the mount in the case of the brush in FIG. 4[0081] a.
The cases fitted with brushes and blocks of powder according to the invention were tested by a group of users, comparatively to conventional cases fitted with a puff as a means of applying the powder. [0082]

ADVANTAGES OF THE INVENTION

Brushes according to the invention and cases fitted with these brushes were acknowledged by the user group as resolving all the problems posed by powder application means of the prior art. [0083]
Indeed, on the one hand, the users considered using a brush to be more appropriate than using a puff for make-up purposes. [0084]
On the other hand, it is much less messy to handle a brush than a puff. [0085]
Furthermore, the brushes according to the invention, particularly through their different texture depending on the tuft considered, allow different effects or looks to be obtained on the face. [0086]
Moreover, given the possibility of having brushes with two application surfaces forming an angle between them, they are adapted to applying make-up to the face, particularly to the cheekbone area, which has a somewhat angular contour. [0087]
Furthermore, as can be seen from the different brush forms shown in the figures, the invention allows a wide variety of new shapes and functions to be offered. [0088]
