Description
[0001] The present invention relates to an applicator for
cosmetics, in particular mascara.
[0002] A common type of applicator, used particularly for pasty
formulations, presents a brush comprising a stem from which
bristles extend generally in a radial configuration. This brush is
immersed in the product contained in a bottle acting as a
container, generally of cylindrical shape; the container opening
through which the brush is inserted presents a collar of suitable
shape, for example funnel shape, with its minor aperture facing the
container interior, and of diameter such as to interfere with the
brush surface, such as to remove any excess product from the
bristles and leave an optimal quantity thereon for uniform and
adequate application. The collar can be of suitable material, for
example preferably soft plastic.
[0003] The stem can comprise two metal wires entwined together to
retain the bristles, which can have the same or different length.
The tips of the bristles define a surface known for brevity as the
brush lateral surface, which can be a surface of revolution
(cylindrical in the case of bristles of the same length) or not,
either symmetrical or non-symmetrical about a longitudinal axis
substantially contained within the stem.
[0004] The applicator comprises a handgrip (capsule) connected to
one end of the stem, for example by a rod of suitable material and
dimensions; usually the handgrip is shaped to act as a cover for
the container, with which it forms a closure for example by means
of corresponding threads. Brushes can also be formed in other ways,
for example with bristles formed integrally with a stem of suitable
material, for example plastic material.
[0005] To facilitate correct product application, brushes have been
proposed having different types of lateral surface, for example
cylindrical, convex conical, sometimes non-symmetrical. The
rigidity of the bristles, dependent on their structure and the
materials used, can vary, bristles of different type also being
usable. However, the proposed forms are not completely satisfactory
and do not enable the mascara to be distributed adequately and
uniformly along the entire length of the longest eyelashes or on
the shortest eyelashes in proximity to the inner corner of the
eye.
[0006] The aforestated problems have now been solved by an
applicator for cosmetics, in particular mascara, formed in
accordance with the technical teachings of the accompanying
claims.
[0007] The invention will be more apparent from the ensuing
description of preferred embodiments thereof, given by way of
non-limiting example with the aid of the accompanying figures, in
which:
[0008] FIG. 1 shows schematically a brush of an applicator
according to the present invention;
[0009] FIG. 2 shows schematically a brush of an applicator
according to a different aspect of the present invention;
[0010] FIG. 3 shows schematically a brush of an applicator
according to a further aspect of the present invention.
[0011] With reference to FIG. 1, this shows that part of an
applicator presenting the brush, comprising a stem 1 presenting the
bristles 2 disposed substantially radially. The brush has one end
connected to a handgrip (not shown), for example by means of a rod
4, and its opposite end 5 free. It can be seen that the brush
presents a make-up application portion 9 of lesser radius, disposed
on the stem in an end position. Moving towards the handgrip a
definition portion of greater radius is present. The make-up
application portion 9 and the definition portion 8 follow each
other towards the handgrip and are preferably in mutual
contact.
[0012] The lateral surface, defined by the tip (end) of the brush
bristles and intersected by a meridian plane (that of the drawing
sheet) containing the brush axis, forms a line 7, 7'.
[0013] If said lateral surface is a solid of revolution, all the
meridian lines are identical, this representing a preferred aspect
of the invention.
[0014] The definition portion 8, as can be noted, has a distance
from the axis A which is always greater than the make-up
application portion, except at the point where these two portions
join together. At this point 10 the line 7, 7' forms an angular
point with its cusp facing the axis A. The concavity of the line 7,
7' hence faces away from the axis A. However the concavity of the
line 7' pertaining to the definition portion and the line 7
pertaining to the make-up application portion can face the axis
(including in the immediate vicinity of the angular point 10). A
short radiused line with its concavity facing away from the axis
can also be provided, in passing between the two portions.
[0015] In practice, that brush part at the definition portion is
configured as a projection of the make-up application part.
[0016] According to a possible aspect, the definition portion 8 has
its concavity facing towards the axis (it preferably being of
ellipsoidal or spherical configuration), while the make-up
application portion extends rectilinearly, parallel to the axis or
convergent therewith. A rounding 11 can be present at its free end,
in the usual manner.
[0017] FIG. 2 represents a brush according to another aspect. In
this case, the definition portion 28 is frusto-conical rather than
spheroidal or ellipsoidal, and converges towards the free end 25,
as far as the point 30 (which in the preceding embodiment was
indicated by 10) where it connects to the make-up application
portion 29, which is again cylindrical.
[0018] For any unspecified details of this embodiment, the
considerations given for the embodiment of FIG. 1 are valid.
[0019] A further embodiment is shown in FIG. 3. In this case the
line 7, 7' presents a discontinuity between the definition portion
38 positioned at a greater distance from the axis 36 and the
make-up application portion 39. In the illustrated example, both
portions extend substantially cylindrically, with generators 7, 7'
parallel to the axis A.
[0020] A frusto-conical configuration converging towards the end 35
could be provided for one or both portions, or ellipsoidal or
spherical forms, particularly the former, can be present, with
their concavity preferably facing the axis.
[0021] In the aforedescribed embodiments innumerable variants are
possible. For example, the described forms can be ellipsoidal,
spherical, frusto-conical, cylindrical, with bevels at the end
portions and with radiused connections between the two portions. In
the present text the term "spherical form" or "ellipsoidal form"
means a portion of a sphere or ellipsoid (ellipsoids or spheres
sectioned by planes perpendicular to the brush axis A).
[0022] It has been found that the applicator of the present
invention is particularly advantageous for its easy and uniform
mascara distribution on the eyelashes.
[0023] It should be noted that while extracting the applicator from
the mascara bottle the collar acts differently on the two brush
portions. Specifically, the collar acts only minimally on the
make-up application portion (of lesser diameter), hence leaving it
much more impregnated with mascara. In contrast, the collar acts
much more decidedly on the definition portion (of greater
diameter), so removing a large part of the mascara present on the
bristles, to hence leave this portion impregnated with a minimum
quantity of make-up.
[0024] The make-up application portion can hence be used to
distribute the mascara (with which this portion is abundantly
loaded) with extreme accuracy (given its small radial dimensions)
over all the eyelashes and in particular on the base of the
eyelashes and on the (difficultly reachable) short eyelashes
present at the ends of the eye. There is also a better "combing" of
the outer eyelashes.
[0025] The definition portion makes it extremely simple to improve
the definition of the tips of the longer eyelashes by combing them
and separating them from each other, so providing them with volume
and definition. This is facilitated by the minimum quantity of
product present on this applicator portion.
[0026] In other respects, the applicator and its package can be
formed in accordance with the known art. For example the stem can
be formed with entwined metal wires as aforestated, or in any other
known manner. The bristles, of equal or different material and
properties, can be of any suitable type according to requirements,
for example bristles of polypropylene, acetal resin, etc., and if
considered opportune can be different in those brush parts relative
to the two meridian line portions.
[0027] The length of that stem part comprising the bristles (brush
length L1+L2) can be similar to that of brushes of known type,
preferably between 20 and 30 mm, and up to 40 mm.
[0028] The length L2 of the definition portion can be for example
between 1/4 and 3/4 of the total, for example between 7 and 25 mm
(preferably 15 mm), with a diameter D2 also between 7 and 25 mm
(preferably 12 mm).
[0029] The length L1 of the make-up application portion can be
between 5 and 20 mm, preferably 15 mm, with a diameter D1 between 4
and 10 mm (preferably 6 mm).
[0030] Advantageously it has been verified that the optimal ratio
between the definition portion diameter D2 and the make-up
application portion diameter D1 is between 1.8 and 2.5, preferably
2.
[0031] The angle .alpha. present at the angular point (10, 30)
between the tangents at the lines 7, 7' can be about 90.degree. as
improperly represented in FIG. 3 (in fact, here the 90.degree.
angle defines a discontinuity in the line 7, 7'), or between
160.degree. and 120.degree. in the configuration of FIGS. 1 and
2.
[0032] In a different embodiment (not shown), the brush presents an
axis A which is not rectilinear but is curved or at an angle to the
axis of the rod 4. All the aforesaid concepts are adaptable to this
case without problem, by properly adapting them to the new
configuration comprising one or more curves.
[0033] The applicator is particularly suitable for mascara of pasty
consistency, however it can also be used with possible
modifications for formulations of other fluidities.
