A DEVICE FOR PACKAGING AND APPLYING A SUBSTANCE

Abstract The present invention relates to a device for packaging and applying a substance, the device comprising: a receptacle (2) for containing the substance; an applicator member (4) ; and a wiper member (7) secured to the receptacle (2) to wipe the applicator member (4) as the applicator member (4) leaves the receptacle (2) , the wiper member (7) including at least one undulating wiper lip (17) with a radially inner free edge defining the orifice through which the applicator member (4) passes, undulations of the wiper lip (17) enabling the wiper lip to deploy under thrust from the applicator member (4).
Full Text The present invention relates to devices for packaging
and applying a substance, in particular a cosmetic, e.g.
makeup or a care product, the device including an applicator
and a wiper member for wiping an applicator member.
Numerous known devices have relatively rigid wiper
members that are liable in the long run to damage the
applicator member, in particular when the applicator member
has bristles or flocking.
European patent application EP—A1—1 050 231 and
international application WO 93/01736 describe wiper members
having flaps that can be folded to facilitate inserting the
applicator member in the receptacle containing the substance.
Patent applications EP-A1-0 627 182, EP-A1-1 481 607, and
US 2003/0196672 disclose wiper members having slots that
facilitate deformation of the wiper member while the
applicator member is being inserted into and/or extracted from
the receptacle containing the substance. Such devices can
lead to wiping that is not entirely satisfactory.
Patent application FR 2 753 058 discloses a wiper member
comprising a sleeve configured to hold a reserve of substance
by a surface tension effect. The section of the sleeve is
constant over its entire length extending along the
longitudinal axis.
US patent No. 4 433 928 teaches using an adjustable wiper
member, in particular a member that is adjustable to the
height of the neck of the receptacle containing the substance
for application.
Finally, patent application EP—A1—0 728 426 discloses a
wiper member capable of deforming elastically when the
applicator member passes therethrough.
There exists a need to further improve devices for
packaging and applying a substance, and in particular to
benefit from a wiper member capable of wiping a wide variety
of applicator members in satisfactory manner, in particular
applicator members presenting a cross-section that is
relatively large compared with the cross-section of the stem
2

and/or that are relatively fragile, e.g. because they include
bristles or flocking.
There also exists a need to leave a more uniform load of
substance on applicator members that may present a very wide
variety of cross-sections.
There also exists a need for a wiper member that can
easily be mounted on the corresponding receptacle.
There also exists a need to avoid the piston effect when
the applicator member is taken out from the receptacle.
In one of its aspects, the invention provides a device
for packaging and applying a substance, in particular a
cosmetic, makeup, or a care product, the device comprising:
• a receptacle for containing the substance;
• an applicator member; and
• a wiper member secured to the receptacle to wipe the
applicator member as it leaves the receptacle, the wiper
member comprising at least one wiper lip having a radially
inner free edge defining an orifice through which the
applicator member passes, the perimeter of the free edge being
strictly greater than the perimeter of the orifice observed in
projection from above, e.g. because of the. presence of
undulations. The perimeter of the free edge may be greater
than the perimeter of the stem that is to be wiped, for
example.
In one of its aspects, the invention also provides a
device for packaging and applying a substance, in particular a
cosmetic, makeup, or a care product, the device comprising:
• a receptacle for containing the substance;
• an applicator member; and
• a wiper member secured to the receptacle to wipe the
applicator member as it leaves the receptacle, the wiper
member comprising at least one undulating wiper lip having a
radially inner free edge defining an orifice through which the
applicator member passes.
The device may include an applicator comprising a stem
with the applicator member being secured to one end thereof.
The presence of undulations enables the wiper lip to
deform more easily as the applicator member passes
3

therethrough while it is being inserted into the receptacle
and/or taken out therefrom, but without thereby losing its
ability to wipe the applicator member in satisfactory manner,
and it can also serve to reduce the piston effect.
The invention also makes it easier to provide a wiper
member capable of adapting to an applicator member presenting
relatively large amounts of variation in its cross-section,
while nevertheless also wiping the stem that supports said
applicator member.
By way of example, the applicator member may present a
maximum transverse dimension that is greater than the diameter
of the portion of the stem that is wiped, when said portion is
circular in section.
Depending on the general orientation of the wiper lip
relative to the direction in which the applicator member is
inserted and taken out, the wiper member may deform more
easily, e.g. during insertion or while the wiper member is
being taken out.
For example, it is thus possible to arrange the wiper lip
in such a manner that it deforms more easily while the
applicator member is being returned into the receptacle than
while it is being taken out. For example by having a wiper
lip that is generally converging towards the bottom of the
receptacle, it is possible to obtain relatively thorough
wiping of the applicator member on each use, while reducing
the risk of damage while the applicator member is being
returned into the receptacle.
The wiper member may be more flexible than at least a
portion of the applicator member that comes into contact
therewith.
At rest, the diameter of the wiper member may be close to
that of the stem, and when the applicator member is inserted
through the wiper member, the undulations of the wiper lip
deploy, thereby making it easier to enlarge the orifice
defined by the wiper lip so as to allow the applicator member
to pass through, but without that generating excessive
pressure that might cause damage.
4

The term "undulations" should be understood as
designating a sequence of indentations and/or projections
formed by the wiper lip when going around its circumference.
They may be curved in shape or they may be in the form of
folds that are alternately concave and convex on going round
the circumference. Each undulation of the wiper lip may
extend, when the wiper lip is observed from above, along an
axis that is oriented radially. All of the axes of the
undulations may intersect substantially at the center of the
orifice defined by the wiper lip.
The axes of the undulations may be oriented substantially
perpendicular to the longitudinal axis of the device or they
may substantially occupy a cone, which cone may converge or
diverge towards the bottom of the receptacle.
At least one undulation of the wiper lip may be oriented
along a curvilinear or rectilinear line that is not concentric
about the longitudinal axis of the device, and in particular
that is radial.
The wiper lip need not have any ribs and/or slots, for
example slots extending parallel to the longitudinal axis of
the device or slots extending perpendicularly to the
longitudinal axis of the device, or indeed slots that are
inclined relative to the longitudinal axis of the device. In
particular, unlike certain prior art wiper members, the wiper
member need not have any slots that are substantially closed
when at rest and that extend longitudinally.
The undulations of the wiper member may vary in amplitude
and in number. The wiper member may, for example, have two to
12 undulations, or four to ten undulations, or indeed five to
nine undulations. They may be distributed regularly or
irregularly. They may all have the same amplitude, or in a
variant they may be of different amplitudes.
Two adjacent undulations may present profiles that are
different.
Advantageously, the free edge of the wiper lip, when not
under stress, does not extend entirely in one plane.
The wiper lip may occupy a midplane that is substantially
perpendicular to the longitudinal axis of the device, or it
5

may generally occupy a cone, either a cone that converges
towards the bottom of the receptacle, or a cone that converges
towards the outlet from the receptacle.
The thickness of the wiper member may be constant, or in
a variant its thickness may vary. For example it may be
thinner at points closer to its free edge and thicker at
points further away from its free edge.
In the circumferential direction and at a given distance
from the longitudinal axis of the device, the wiper member may
present a thickness that is substantially constant, e.g.
varying by less than 10% on one complete revolution. However
its thickness may vary on going towards the longitudinal axis.
The thickness of the wiper lip may lie in the range
0.1 millimeters (mm) to 0.8 mm, for example. More
particularly, it may be about 0.2 mm at the free edge and
about 0.5 mm at points of the wiper lip that are further from
the free edge, e.g. at the periphery of the wiper lip.
The wiper lip may deploy under thrust from the applicator
member, possibly prior to stretching in elastic manner.
During deployment of the wiper lip, its undulations may tend
to flatten out, with the wiper lip being observed from the
center of the orifice it defines.
The orifice of the wiper member may be configured to have
an aptitude for passing from a small diameter suitable for
wiping the stem to a larger diameter enabling the applicator
member to be wiped, without necessarily relying on significant
elongation of the material constituting the wiper lip.
The orifice of the wiper lip may be circular, or in a
variant it may be non-circular, e.g. oval, elliptical, kidney-
shaped, or polygonal, e.g. square or rectangular. The shape
of the orifice may be selected as a function of the shape of
the cross-section of the stem and as a function of the manner
in which the applicator is taken out from the receptacle, for
example whether it turns about its own axis or not.
The wiper lip may deform more than the applicator member
while the applicator member is passing through the orifice.
6

The total height of the wiper member, measured along the
longitudinal axis of the device may be greater than that of
the wiper lip and it may remain substantially constant in use,
in particular when the applicator member is taken out from the
receptacle or is introduced therein.
The wiper lip may press against the stem at at least two
distinct levels along the longitudinal axis of the device, for
example in a manner that is discontinuous in the
circumferential direction in the vicinity of the extrema of
the undulations.
The cross-section of the stem of the applicator may be
substantially constant at least over a major fraction of the
length of its portion that comes into contact with the wiper
lip while the applicator is being taken out. Under such
circumstances, the section of the orifice defined by the wiper
lip may correspond substantially to the outside cross-section
of said portion of the stem. The stem may present a distal
portion that tapers in the proximity of the applicator member,
and in particular a distal portion that is conical, which can
improve the quality of wiping.
The applicator member may comprise at least one of: a
brush with an optionally-twisted core, a comb, a tuft of
bristles implanted in the stem to form a paint brush, a
spatula, flocking, a foam, and felt.
The applicator member may, for example, comprise a brush
which may have any shape that is suitable for the making up
that is to be performed. In an embodiment of the invention,
the brush presents an envelope surface in the vicinity of its
proximal end that has a cross-section that decreases going
away from the distal end of the brush. The brush may present
an envelope surface of cross-section that goes through a
maximum between its two longitudinal ends.
The brush may also present an envelope surface of cross-
section that passes through a minimum between its two
longitudinal ends.
The brush may be twisted with a left-hand pitch, as
described in patent application EP 0 611 170, the content of
which is incorporated herein by reference.
7

A wiper member in accordance with the invention can be
used in a variety of packaging devices.
The wiper member may be made out of at least one of the
materials in the following list: an optionally vulcanized
elastomer, silicone, nitrile rubber, butyl rubber, ethylene
propylene terpolymer rubber (EPDM), thermoplastic elastomer,
styrene isoprene styrene (SIS), SEAS, Hytrel®, Pebax®,
polyethylene (PE), polyethylene terephthalate (PET), polyamide
(PA), polyvinyl chloride (PVC), and polystyrene (PS) .
The wiper member may be mounted on a neck of the
receptacle.
The receptacle may include a neck and the wiper member
may include an assembly skirt suitable for securing the wiper
member in the neck. Where appropriate, the wiper member may
include an annular rim that comes to bear against the top
surface of the neck of the receptacle.
In a variant, the wiper member may, for example, be
overmolded on the receptacle or on a support part, or in a
variant it may be secured to the neck of the receptacle by
clamping between the receptacle and a support part. The wiper
member may, for example, be secured to a ring mounted on the
neck of the receptacle.
The device may include means for providing sealing when
the receptacle is closed. By way of example, sealing may be
provided by the wiper member or by some other part coming to
press against the neck of the receptacle.
The wiper member may be mounted in a device having an
adjustable wiper member, including a moving portion. Such a
configuration can enable the wiper member to be subjected to
greater changes in diameter by a displacement of the moving
portion.
The receptacle may contain a cosmetic, makeup, or a care
product, for example at least one of: a mascara, lipstick,
e.g. a liquid lipstick, lip gloss, foundation, nail varnish,
eye shadow, eye liner, or blush.
The wiper member may comprise flocking on all or part of
its inside surface, and in particular on the wiper lip.
8

The substance may be for application to keratinous
fibers, to the eyelashes, and/or to the eyebrows, to
fingernails or toenails, for example, to the skin, to mucous
membranes, to the lips, to the eyelids, or to the cheeks.
The present invention also provides a wiper member as
such.
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 diagrammatic fragmentary axial section
view of a packaging and applicator device constituting a first
embodiment of the invention;

• Figures 7 to 9 are views analogous to Figure 2 showing
variant embodiments of the invention;
• Figure 10 is a diagrammatic and fragmentary cross-
section view of a variant embodiment of a wiper member in
accordance with the invention;
• Figure 11 is a view seen looking along arrow XI of
Figure 10;
• Figures 12 to 14A are views analogous to Figure 4
showing variant embodiments;
• Figures 15 to 17 are diagrammatic and fragmentary
cross-section views of variant embodiments of devices in
accordance with the invention; and
• Figures 18 to 26 show variant embodiments of the
applicator member.
Figure 1 shows a packaging and applicator device 1
comprising a receptacle 2 filled with a substance P containing
a cosmetic, makeup, or a care product, e.g. a mascara.
The device 1 further comprises an applicator 3, itself
comprising an applicator member 4 at a first end of a stem 5,
9

the stem being connected at its second end to a closure cap 6
for closing the receptacle 2, being suitable for screw
fastening thereto. The stem 5 in the example described is of
constant circular section, however the stem of the applicator
could present a different section.
In the example shown in Figure 1, the applicator member 4
is constituted by a brush comprising a metal core twisted to
left or to right, with the bristles being clamped between the
turns of the core. At its proximal end, the brush 4 may
include a chamfer 4a. Naturally, it would not go beyond the
ambit of the present invention for the brush to have a core
that is not twisted or for the applicator to be of some other
kind, as described below.
In the example described, the longitudinal axis of the
applicator member 4 coincides with the longitudinal axis of
the stem 5 and with the axis of the device 1, however the
longitudinal axis of the applicator member 4 could be oriented
in some other way, e.g. substantially perpendicularly to the
longitudinal axis of the stem, e.g. when using a flat stem.
The applicator member 4 could also have a longitudinal axis
that is not rectilinear. The applicator member 4 may have
bristles of different kinds and/or lengths.
The device 1 includes a wiper member 7 shown on its own
in Figures 2 and 3, having a longitudinal axis X and secured
in the neck 8 of the receptacle 2, e.g. by snap-fastening.
For this purpose, the wiper member 7 may include a catch-
forming collar 9 that is arranged to snap beneath the neck 8.
In a variant that is not shown, the collar 9 is replaced by a
shoulder in the outside surface of the wiper member.
The wiper member 7 has an assembly skirt 14 of
longitudinal axis X, terminated by a rim 12 that comes to bear
against the end face 13 of the neck 8 of the receptacle 2, and
that serves advantageously to ensure that the receptacle 2 is
sealed when closed by being compressed by the cap 6 when it is
fully tightened on the neck 8. Naturally, the cap 6 could be
secured onto the receptacle other than by screw fastening, for
example it could be secured by snap-fastening or by friction.
10

In a variant, the wiper member may include an annular rim
defining a downwardly open groove in which the top end of the
neck 8 engages.
A wiper lip 17 is connected to the bottom surface of a
bottom portion of the assembly skirt 14 extending beneath the
catch-forming collar 9.
The wiper lip 17 defines internally an orifice 22 through
which the applicator member 4 passes on being taken out of the
receptacle 2.
In the embodiment of Figures 1 to 3, the wiper lip
generally occupies a cone that converges towards the bottom of
the receptacle, the cone having a generator line W at an angle
a relative to the axis X.
In a variant, and as shown in Figure 7, the wiper lip 17
could generally occupy a midplane perpendicular to the
longitudinal axis of the device. In another variant, as shown
in Figure 8, the wiper lip 17 could generally occupy a cone
that converges towards the outlet of the receptacle.
In the example of Figures 1 to 3, the thickness of the
wiper lip tapers towards the radially inner free edge 23
thereof. The thickness of the wiper lip in the vicinity of
its free edge 23 may be about 0.2 mm, for example, while it is
about 0.5 mm where the wiper lip 17 joins the assembly skirt
14.
The tapering of the wiper lip 17 towards its free edge 23
can make it easier to deform while the applicator member is
being inserted into or taken out from the receptacle 2.
In a variant, the thickness of the wiper lip 17 may be
constant, as shown in Figure 9.
The wiper lip 17 presents undulations 20 extending around
the orifice 22.
In the example of Figures 1 to 3, the wiper lip 17
presents undulations 20 that are all identical, in particular
four undulations 20 that are uniformly distributed around the
orifice 22, so that two successive undulations are angularly
spaced apart by 90°, the undulations being substantially
sinusoidal in profile, as shown in the developed view of
Figure 4 .
11

The wiper lip 17 could have some other number of
undulations 20, e.g. a number lying in the range three to 12,
or in the range four to ten, or indeed five to nine.
Figures 10 and 11 show a wiper member 7 having a wiper
lip 17 with nine undulations 20 that are uniformly distributed
around the orifice 22.
The undulations may form angular folds, as shown in
Figure 12, or crenellations as shown in Figure 13. The
undulations need not be concentric about the longitudinal axis
of the applicator.
The undulations may be constituted by a repeating
periodic pattern.
It would not go beyond the ambit of the present invention
for the undulations to be distributed irregularly. At least
one undulation could be different from the others, e.g. in
shape or in amplitude.
By way of example, Figure 14 shows an embodiment of a
wiper lip that comprises a mixture of curved undulations and
angular undulations.
The undulations may extend on either side of a midline,
in balanced or in unbalanced manner. In Figure 14A, it can be
seen that the undulations project to one side only of the
wiper lip.
The wiper member may be made in at least one of the
materials in the following list: optionally vulcanized
elastomer, silicone, nitrile rubber, butyl rubber, EPDM,
thermoplastic elastomer, SIS, SEAS, Hytrel®, Pebax®, PE, PET,
PA, PVC, and PS.
The above-described device is used as follows, as shown
in Figures 5 and 6.
While the applicator member 4 is being inserted into the
receptacle 2, as shown in Figure 5, or while it is being taken
out, as shown in Figure 6, the undulations 20 are deployed,
thereby making it easier for the applicator member to pass
through.
The wiper lip 17 may also deform elastically by its
material stretching.
12

Figure 15 shows a wiper member 7 having a wiper lip 17
that is overmolded directly onto the neck 8 of the receptacle
2.
The wiper member 7 could also be secured in the neck 8 of
the receptacle 2 not by snap-fastening or by overmolding, but
by any other means, e.g. by adhesive, heat-sealing, or
friction, and it could be made without the catch-forming
collar 9.
By way of example, Figure 16 shows a wiper member 7
having a wiper lip 17 secured to a support part 25, itself
snap-fastened on a portion forming the neck 8 of the
receptacle 2. By way of example, the wiper lip 17 may be
overmolded or stuck onto the support part 25 or it may be held
by friction between the support part 25 and the neck 8. The
support part 25 in the example described is constituted by a
ring snapped onto the neck 8, however it would not go beyond
the ambit of the present invention for the support part 25 to
be secured to the neck 8 by adhesive or by overmolding, for
example.
The support part 25 could be made of a material other
than that of the neck 8, for example the materials used could
present different hardnesses.
In another variant, the device could include means for
deforming the wiper member, e.g. for modifying the dimensions
of the orifice and/or the range of deformation of the wiper
lip as a function of the desired wiping result.
For example, Figure 17 shows a device comprising a first
element 30 and a second element 40 that is capable of turning
relative to the first element 30 about the longitudinal axis X
of the device.
The first element 30 has a generally cylindrical wall 31
of axis X, extended at its top portion by a neck 32 connected
at its bottom end to a transverse wall 33. In the example
shown the first element 30 also presents an internal extension
34 of tubular shape, defining an insertion cone 35 for the
applicator member, that converges towards the inside of the
receptacle, and that is provided at its bottom end with an
annular bead 36.
13

In the example described, the second element 40 comprises
a generally tubular body 41 about the axis X, that is closed
at its bottom end by a bottom wall 42. The bottom portion 43
of the body 41 is surrounded by an outer skirt 44. The top
end of the skirt 44 joins the transverse wall 45 which is
connected perpendicularly to the body 41. The wall thereof
becomes thicker above the transverse wall 45 so as to form a
cylindrical guide surface 46 of outside diameter matching the
inside diameter of the bottom end of the wall 31. The height
of the guide surface 46 is sufficient so that regardless of
the angular position of the second element 40 relative to the
first element 30, the surface 46 remains substantially in
contact with the inside surface of the wall 31.
At its top end, on its radially outside surface, the body
41 presents an annular bead 47 that serves for securing the
wiper member 7. The wiper member has an annular rim 12 at its
top end arranged to snap-fasten onto the bead 47. The
assembly skirt 14 extends in the annular space formed between
the inside extension 34 and the top portion of the body 41.
The second element 40 is provided with a stud 50 and the
first element 30 includes a slot 51 passing through the wall
31 having a longitudinal axis Y that extends over a portion of
a helix, for example, over an annular extent of about 120°,
for example, around the axis X. The inclination of the slot
51 makes it possible, for example, to obtain a maximum stroke
d in the axial direction lying in the range 2 mm to 3 mm as
the stud 50 passes from one extreme position to the other, on
the second element 40 turning relative to the first element
30.
When the second element 40 is in its low abutment
position with the stud 50 bearing against the left-hand end of
the slot 51, the bottom end 49 of the inside extension 34
cannot significantly deform the undulations 20 and the wiper
lip 17 of the wiper member 7. Wiping is then at a maximum and
the load of substance carried by the applicator member 4 is at
a minimum.
14

When the second element is turned, the stud 50 moves
along the slot 51 and rises relative to the first element 30.
The inside extension 34 presses downwards against the wiper
lip 17 and the undulations 20 are deployed. At the end of the
turning stroke, the stud 50 reaches its high abutment position
corresponding to the left-hand half section in Figure 17.
The person skilled in the art can select the degree of
deformation of the wiper member as a function of the desired
result, e.g. depending on whether or not wiping is to occur
regardless of the position of the stud in the slot, or whether
it is to be possible in a given position to wipe only against
the edge of the inside extension 34.
By way of example, there may be two positions
corresponding respectively to wiping against the deformable
wiper member 7 and to wiping against the inside extension 34.
In a variant, it is also possible to have in at least one
position no wiping at all, with the inside extension 34 being
made in such a manner that it cannot normally wipe the
applicator member.
The wiper member 7 may receive any suitable surface
treatment or coating, e.g. flocking.
The bristles of the brush 4 in the embodiment of Figure 1
extend in the example described all around the core, however
it would not go beyond the ambit of the present invention for
the bristles to occupy a smaller annular sector. The brush
may include at least one concave facet or notch.
Where appropriate, the brush may also have an envelope
surface S of cross-section that is not constant, e.g. passing
through a single maximum as shown in Figure 18, or through a
minimum and a maximum, as shown in Figure 19.
The brush 4 may in particular be of the kind described in
US patent No. 5 876 138, with the minimum section being less
than the smallest section of the orifice of the wiper member,
for example.
Figures 18 and 19 show that the stem 5 may have a
tapering portion 5a at its distal end, e.g. of conical shape.
The presence of such a portion 5a can contribute to further
improving wiping.
15

In a variant that is not shown, the stem 5 has a narrow
portion which occupies a position level with the wiper lip 17
when the receptacle is closed and the applicator is in place.
The narrow portion serves to avoid compressing the wiper lip
while at rest, and thus serves to reduce any risk of the wiper
portion becoming permanently deformed.
The invention is not limited to one particular type of
applicator member, and by way of example the applicator member
could be other than a mascara brush, e.g. it could be a comb
as shown in Figure 20, a paint brush as shown in Figure 21, a
pointed felt tip as shown in Figure 22, a foam as shown in
Figure 23, an optionally flocked endpiece extending along an
axis parallel to the longitudinal axis of the stem as shown in
Figure 24, or making an angle relative thereto, as shown in
Figure 25.
The applicator member may have a maximum transverse
dimension that is greater than the diameter of the stem 5.
The cross-section of the applicator member may be
circular or non-circular. By way of example, Figure 26 shows
an applicator member having cross-section that is
substantially square, with elements projecting from its
corners.
Naturally, the characteristics of the various embodiments
described can be combined with one another in variants that
are not shown.
The term "comprising a" should be understood as being
synonymous with "comprising at least one" unless specified to
the contrary.
