Description
FIELD OF THE INVENTION
[0001] The invention relates to the field of cosmetic product
applicators, particularly brushes intended to apply to the face a
solid product in a divided state such as a powder, or again pencil
brushes intended to apply to the nails a liquid product such as a
nail varnish.
PRIOR ART
[0002] Numerous applicators are already known such as brushes
intended to apply a make-up powder to the face, mascara brushes
intended to apply mascara to the eyelashes, pencil brushes intended
to apply nail varnish.
[0003] These applicators may or may not engage with a dispenser of
said cosmetic product.
[0004] Generally, these applicators, typically longitudinal,
include a first part forming manual gripping means, a second
intermediate part integral with said first part at one end, and at
the other end, acting as a support for an application material, and
a third part forming said application material.
[0005] These applicators may include a second flexible part, as is
known for example in U.S. Pat. Nos. 4,509,540 and 6,341,912.
PROBLEMS POSED
[0006] In many cases, known applicators on the one hand allow only
a single method of manually gripping said applicator, with the
result that these applicators allow only one type of effect to be
obtained on the medium.
[0007] On the other hand, they do not therefore allow the way of
using the applicator to be modulated or controlled manually, with
the result that there is a need for applicators that allow great
sensitivity and great delicacy in applying said product to said
medium to be obtained.
DESCRIPTION OF THE INVENTION
[0008] According to the invention, the applicator of a product,
typically a brush intended to apply a cosmetic product such as a
make-up powder to a medium such as the skin, includes a) a
so-called lower part forming a typically rigid means of manually
gripping said applicator, b) a so-called central part, anchored to
said lower part by its lower end, forming a means of resiliently
straining said applicator under a manual constraint, c) a typically
rigid so-called upper part bearing an application material, said
upper part being anchored to said central part at its upper end,
and d) said application material anchored to said upper part, and
is characterised in that:
[0009] 1) said lower and central parts have mean visible
cross-sections, denoted respectively S.sub.A and S.sub.B such that
the relative deviation ER.sub.1=|S.sub.A-S.sub.B|/S.sub.A is less
than 0.1,
[0010] 2) said lower and central parts form a first longitudinal
component having an axial direction, said first component having a
first shape factor L/D between 3 and 7, L and D denoting
respectively the largest axial dimension or axial length of said
first component, and the largest dimension or diameter of said
first component perpendicular to said axial direction.
[0011] The term "visible cross-section" is used for that
cross-section which is formed by the most peripheral radial parts
which alone can be grabbed manually and thus form a grip surface.
Geometrically speaking, this is the casing surface, typically
cylindrical, parallel to said axial direction, which embodies
either said lower part in the case of the cross-section S.sub.A, or
said central part in the case of the cross-section S.sub.B.
[0012] A "mean cross-section" is considered when the gripping
surface of said lower or central part is not straight but includes
a withdrawn part or a raised part.
[0013] This applicator resolves the problems posed since it allows
said applicator to be gripped manually over the whole length L of
said first component, including therefore over said central part,
which allows said manual constraint to be modulated or controlled
manually, if necessary, and thus provides great sensitivity and
great delicacy in applying said product to said medium, such as the
face.
DESCRIPTION OF THE FIGURES
[0014] FIGS. 1a to 2f, 4a and 4b are side views of applicators (1)
in the form of brushes (1').
[0015] In FIG. 1a, the resiliently straining central part (3) is a
helical spring (35) anchored to the lower part (2) by means of a
central axial projection (22) anchored to the lower end (30) of
said central part (3), and anchored to said upper part (4) by a
first portion (40) forming an axial projection anchored to the
upper end (31) of said central part (3).
[0016] FIGS. 1b and 1c include as the central part (3) a succession
or alternation (34) of full parts (340) and hollowed-out parts

of said lower part (2) and of said central part (3)
respectively.
[0018] In FIG. 1b, said succession (34) forms a component cast in
one piece and anchored to said lower part (2) by means of a cavity
(23) formed at the upper end of said lower part.
[0019] FIG. 1d shows a photograph of a brush (1,1') whose lower (2)
and central (3) parts form a so-called first component (6) of the
same diameter over its whole length, and typically forms a moulded
component cast in one piece (8).
[0020] In FIG. 1e, similar to FIG. 1d, said central part (3)
includes 3 helical threads (32), the core of said central part (3)

is variable over all or part of the length of said component cast
in one piece, as shown in FIG. 4c.
[0025] In this figure, said lower (2), central (3) and upper (4)
parts have one and the same diameter.
[0026] FIGS. 2e and 2g show the situation where said central part

projection (22) of said lower part and a projection formed by said
first portion (40) of said upper part (4).
[0027] In FIG. 2f, the central part (3) forms, with the lower part
(2) a telescopic device (36) which includes a rod (360) able to be
displaced in a cavity (20) formed in said lower part, an external
helical spring (361) exerting pressure against said upper part (4)
while being supported against said lower part (2).
[0028] The cavity (20) has been closed up at its lower end by an
auxiliary applicator (1'').

an applicator pressed against an application medium (9), said lower
(2), central (3) and upper (4) parts being of rectangular
cross-section, so as to have, by a 90.degree. rotation, two ways of
bending said central part (3) of very different amplitude.
[0030] FIG. 3a represents one way of bending said central part (3)
forming a beam portion of "substantial" relative thickness, whereas
FIG. 3b represents a way of bending said central part (3) forming a
beam portion of "reduced" relative thickness.

(4) parts has been shown in dotted lines, above said lower part
(2).
[0032] FIGS. 4a and 4b show another embodiment in which a rigid
bush (21') is able to slide from said lower part (2) to said
central part (3), so as to rigidify said central part (3) if need

DETAILED DESCRIPTION OF THE INVENTION
[0040] According to the invention, said central (3) and upper (4)
parts may have mean visible cross-sections, denoted S.sub.B and
S.sub.C respectively such that the relative deviation
ER.sub.2=|S.sub.B-S.sub.C|/S.sub.B is less than 0.1, in such a way
that said lower (2), central (3) and upper (4) parts of said
applicator (1,1') form a second longitudinal component (7) of
length L' and of shape factor L'/D>L/D.
[0041] As shown in the figures, the applicators of the invention
are longitudinal applicators, with a relatively high shape factor
L/D or L'/D, as shown in FIGS. 1d and 1e.
[0042] As shown for example in FIGS. 1b to 2e, said central part
(3) forming said means of resiliently straining said applicator
under a manual constraint, may include a material chosen by its
nature and/or cross-section, in such a way that said central part
(3) is able to strain when said manual constraint is exerted
typically during said application of said product to said medium
(9), then is able to resume its initial shape as soon as said
manual constraint ceases.
[0043] According to the invention, and as shown in FIGS. 3a and 3b,
said strain may include bending.
[0044] As shown in FIG. 2f, said strain may include axial
compression.
[0045] But, in the situation in FIG. 1a, said strain may include
both bending and compression.
[0046] According to one embodiment of the invention, and as shown
for example in FIG. 2b, said lower (2) and central (3) parts may
include or be formed of different materials, a first and a second
material respectively, said second material having mechanical
characteristics, typically bending and compression moduli lower
than the bending or compression moduli of said first material.
[0047] Said first material may be constituted by or include a
plastic material, typically a non-elastomeric thermoplastic
material, and said second material may be constituted by or include
an elastomer.
[0048] However, as shown in FIG. 2d, said lower (2) and central (3)
parts may include or be formed of one and the same material,
typically an elastomer or a polymer mixture including an
elastomer.
[0049] Typically, said lower (2) and central (3) parts may have one
and the same cross-section, and form a first typically cylindrical
component (6), which is advantageous for easy manual gripping, and
to obtain different application effects depending on whether the
gripping fingers are farther from or nearer to said upper part
(4).
[0050] According to one variant of the invention, shown for example
in FIGS. 1b and 1c, said central part (3) may have, over all or
part of its axial length, a minimum material cross-section
S.sub.Bm, typically less than 0.5.S.sub.A, selected to obtain said
strain under manual constraint.
[0051] According to another variant shown in FIGS. 1e and 2c, said
central part (3) may include a plurality of N axial or helical
threads (32), each thread (32) having a material cross-section
S.sub.F, such that S.sub.Bm is equal to N.S.sub.F, with N typically
between 2 and 6.
[0052] According to another variant shown in FIG. 2a, said central
part may have an axial profile in the shape of a bobbin (33) the
minimum cross-section of said bobbin (33) being S.sub.Bm.
[0053] According to another variant shown in FIGS. 1b and 1c, said
central part (3) may have an axial succession or alternation (34)
of full parts (340) and typically annular hollowed-out annular
parts (341), said hollowed-out parts (341) having said material
cross-section S.sub.Bm.
[0054] According to another variant shown in FIG. 1a, said central
part (3) may form or include a helical spring (35), either of
metal, or of a plastic material forming a helix of external
diameter D.sub.H typically close to D.
[0055] According to the variant shown in FIG. 2f, said central part
(3) may form a telescopic system (36) with a central rod (360) able
to penetrate into an axial cavity (20) formed in said lower part
(2) and a helical spring (361), either of metal, or of a plastic
material, surrounding said central rod (360).
[0056] As shown in FIGS. 1c, 1d, 2a, 2c, 2d and 4d, said lower (2)
and central (3) parts may form a moulded component cast in one
piece (8).
[0057] As shown in FIGS. 5a to 6b, said moulded component cast in
one piece (8) may be a hollow component, typically of elastomer,
and preferably of silicon resin, said central part forming a
typically undulating surface having greater bending capability than
said non-undulating lower part (2).
[0058] But, as shown in FIGS. 1a, 1b, 2b and 2e, said lower (2) and
central (3) parts may form distinct components anchored by an
assembly means (61) typically by being snapped on, by bonding or by
welding.
[0059] In an applicator (1) according to the invention, and as
shown in most of the figures:
[0060] a) said application material (5) may include a material
absorbent of said cosmetic product, and typically a plurality of
bristles (50) typically parallel and orientated along said axial
direction (60), and,
[0061] b) said upper part (4) may form a double sleeve (4'), with a
first portion (40) for anchoring to said central part, and with a
second portion (41) for anchoring to said plurality of bristles
(50), so as to form a brush (1') or a pencil brush (1'').
[0062] Typically, said lower (2), central (3) and upper (4) parts
may have a round or oval or polygonal external transverse
cross-section, typically constant over said length L or L'.
[0063] However, said lower (2) central (3) and upper (4) parts may
have a flattened external transverse cross-section with a thickness
e such that D/e is between 2 and 6, so as to form a two-dimensional
applicator able to be housed in a dispenser of said cosmetic
product.
[0064] According to another variant of the invention, said minimum
material cross-section S.sub.Bm may be a rectangular cross-section
of length l and width l' with a shape factor l/l' between 2 and 4,
in such a way that said applicator (1; 1', 1'') has two distinct
levels of resistance to bending depending on whether said bending
constraint is exerted parallel to the direction of said length l or
said width l'.
[0065] FIGS. 3a and 3b show the situation where the cross-sections
S.sub.A and S.sub.B have such a rectangular side cross-section 1
and 1'.
[0066] As shown in FIGS. 4a and 4b, said lower part (2) may include
a locking means (21) typically a sliding bush (21') so as to
prevent, if need be, said central part (3) from undergoing said
strain under said manual constraint.
[0067] Another purpose of the invention is constituted by a process
of manufacturing an applicator according to the invention, wherein
said component cast in one piece (8) can be formed typically by
injection moulding in sequence of said first and second
materials.
[0068] The applicator in FIG. 1d was made in this way.
[0069] According to another embodiment of this process, and as
shown in FIGS. 4c and 4d, said component cast in one piece (8) can
be formed typically by simultaneous injection moulding of said
first and second materials, A and B, with pre-set profiles of
concentration C.sub.A and C.sub.B along said length L of said
component cast in one piece, said profile C.sub.A relating to said
first material and said profile C.sub.B relating to said second
material, in such a way that said component cast in one piece
typically has a minimum resistance to bending in said central
part.
EMBODIMENT EXAMPLES
[0070] Brushes (1,1') according to FIGS. 1a to 2f, according to
FIGS. 3a to 4b, and according to FIG. 4d have been
manufactured.
[0071] To do this, on the one hand said first longitudinal
components (6) constituted by said lower (2) and central (3) parts
were manufactured.
[0072] On the other hand said upper parts (4) fitted with said
application material (5) were manufactured or supplied.
[0073] Said longitudinal components (6) were then assembled, by
being snapped on or by bonding, with said upper parts, fitted with
