Description
[0001] This application is a CIP of U.S. application Ser. No.
10/666,368, filed Sep. 19, 2003, the contents of which are
incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] Mascaras are commonly prepared as wax-based formulations
according to two types. Washable mascaras, which can be removed
with soap and water, generally come in the form of an emulsion of
waxes in water such as creams, as well as in gels. Waterproof
mascaras, which require use of oils for removal, generally come in
the form of dispersions of waxes in organic solvents.
[0003] Each type of mascara has advantages and disadvantages.
Application of washable mascaras enhances volume; that is, they
thicken the eyelashes. However, they are prone to smudge such as
when rubbed. In addition, they are not resistant to water.
Waterproof mascaras on the other hand are relatively
water-resistant and are less likely to run or smudge. However,
unlike washable mascaras, they cannot be removed simply with soap
and water. They require the use of organic based cleansing agents
such as mineral oil.
[0004] There have been many developments in cosmetics for
application to eyelashes and eyebrows aimed at improvement one or
more of these properties, or other properties such as ease of
application, homogeneity, comfort and good hold. For example,
mixtures of waxes have been used to combine properties such as film
hardness and adhesion to the lash. See, e.g., WO-A-95/15741. U.S.
Pat. No. 6,464,967 teaches the use of specific polyolefin waxes in
mascara compositions. U.S. Pat. No. 6,375,941 is directed to a
wax-free mascara composition that contains film-forming
polyurethane. U.S. Pat. No. 5,879,668 teaches waterproof mascara in
the form of a water-in-oil (W/O) emulsion in which water (the
disperse phase) is emulsified in oil (the continuous phase). The
oil is preferably a C.sub.10-C.sub.14 saturated, linear or
branched, hydrocarbon, more preferably a C.sub.11-C.sub.13
saturated, linear or branched, hydrocarbon, more preferably a
branched C.sub.12 saturated hydrocarbon such as isododecane. Of
course, mixtures of these hydrocarbons may be used and often are
provided by commercial "technical" grades of these hydrocarbons.
The emulsions are contain solid particles, preferably pigment
particles and preferably at least two different types of
surfactants, one being an a "oil surfactant" having a
hydrophobic-lipophobic balance (HLB) of from 3-4.5, the other being
a "water surfactant" having an HLB of 5.5-7.5.
SUMMARY OF THE INVENTION
[0005] A first aspect of the present invention is directed to a
method of applying mascara to eyelashes, comprising: a) applying a
washable mascara composition to the eyelashes; followed by b)
applying a waterproof mascara composition to the eyelashes, wherein
the washable mascara composition, the waterproof mascara
composition, or both, contain fibers. Eyelashes treated in
accordance with the method of the present invention--which includes
real and false eyelashes--may have enhanced thickness and exhibit
greater water- and smudge-resistance, and ease of removal, compared
to typical waterproof and washable mascaras when used alone.
[0006] A second aspect of the present invention is directed to a
product or system for applying mascara to eyelashes, comprising a)
a first reservoir that contains a washable mascara composition, b)
a second reservoir that contains a waterproof mascara composition,
wherein the washable mascara composition, the waterproof mascara
composition, or both contain fibers, and c) at least one applicator
comprising first and second applicator members for applying the
respective mascara compositions.
[0007] A third aspect of the present invention is directed to a
package containing a system for applying mascara to eyelashes,
comprising a) a first reservoir that contains a washable mascara
composition, b) a second reservoir that contains a waterproof
mascara composition, wherein the washable mascara composition, the
waterproof mascara composition, or both contain fibers, and c) at
least one applicator comprising first and second applicator
elements or members for applying the respective mascara
compositions.

DETAILED DESCRIPTION
[0011] Washable mascaras can be removed simply by use of soap and
water. Waterproof mascaras are not as easily removable, and require
use of oil such as mineral oil. Washable or aqueous mascaras
generally come in the form of an emulsion of waxes in water
(sometimes referred to as cream mascaras), or gels, whereas
waterproof mascaras generally come in the form of dispersions of a
fatty phase that includes one or more waxes in organic solvents
(which when lacking water are sometimes referred to as anhydrous
mascaras), or water-in-oil emulsions (see, e.g., U.S. Pat. No.
5,879,668). Washable mascaras and waterproof mascaras may contain
many similar ingredients (e.g., waxes and film-forming polymers),
the main differences between them being in the relative amounts of
the ingredients, particularly water. Generally, water content of
washable mascaras ranges from about 20 to about 80% by weight, and
preferably from about 30 to about 60% by weight of the mascara
composition. In contrast, water content of waterproof mascaras
generally ranges from about 0 to about 60% by weight, and
preferably from about 0 to about 35% by weight of the mascara
composition. One or more water-miscible solvents may also be
present in either type of mascara. Examples include lower
monoalcohols containing from 1 to 5 carbon atoms, C.sub.3-C.sub.4
ketones and C.sub.3-C.sub.4 aldehydes. A preferred water-miscible
solvent is ethanol. The content of water-miscible solvents
generally ranges from about 0.1% to about 15% by weight, and
preferably from about 1% to about 8% by weight relative to the
total weight of the mascara composition.
[0012] Washable and waterproof mascaras usually have different
viscosities. Viscosity is important from the standpoints of fast
and easy application of the composition, as well as uniform coating
over the entire length of the eyelashes. Generally, viscosity of
washable mascaras ranges from about 10 to about 60 pascal seconds
(Pa*s), and preferably from about 20 to about 40 Pa*s, whereas
viscosity of waterproof mascaras ranges from about 10 to about 70
Pa*s, and preferably from about 10 to about 40 Pa*s. Viscosity is
measured at 25.degree. C. with a Rheomat RM 180 viscometer fitted
with a No. 4 rotor, wherein the measurement is carried out after
spinning the rotor for 10 minutes (after which time stabilization
of the viscosity and of the rotor spin speed are observed), at a
shear rate of 200 s.sup.-1.
[0013] Viscosity may be adjusted by adding a thickener.
Representative examples include cellulose-based thickeners, for
example, water-soluble cellulose-based thickeners, such as
hydroxyethylcellulose, methylcellulose, hydroxypropylcellulose and
carboxymethylcellulose. Among these thickeners, specific examples
include the gums sold under the name "Cellosize QP 4400 H" by the
company Amerchol, guar gum, in particular, those sold under the
name Vidogum GH 175 by the company Unipectine and under the name
Jaguar C by the company Meyhall, the quaternized guar gum sold
under the name "Jaguar C-13-S" by the company Meyhall, nonionic
guar gums comprising C.sub.1-C.sub.6 hydroxyalkyl groups, e.g.,
hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.
Such guar gums are sold, in particular, under the trade names
Jaguar HP8, Jaguar HP60, Jaguar HP120 and Jaguar HP105 by the
company Meyhall, or under the name Galactasol 40H4FD2 by the
company Aqualon. Other examples of thickeners include xanthan gum,
carob gum, scleroglucan gum, gellan gum, rhamsan gum and karaya
gum, alginates, maltodextrin, polysaccharide resins such as starch
and its derivatives, hyaluronic acid and its salts, clays, and, in
particular, montmorillonites, hectorites and laponites, crosslinked
polyacrylic acids, such as the "Carbopol" products from the company
Goodrich, the polyglyceryl (meth)acrylate polymers sold under the
names "Hispagel" or "Lubragel" by the companies Hispano Quimica or
Guardian, polyvinylpyrrolidone (PVP), polyvinyl alcohol,
crosslinked acrylamide polymers and copolymers, such as those sold
under the names "PAS 5161" or "Bozepol C" by the company Hoechst,
"Sepigel 305" by the company SEPPIC, crosslinked
methacryloyloxyethyltrimethylammonium chloride homopolymers sold
under the name "Salcare SC95" by the company Allied Colloid, and
associative polymers and, in particular, associative
polyurethanes.
[0014] The mascaras suitable for use in the present invention
typically contain a thickener in an effective amount for the
composition to have the viscosity as defined above. The thickener
content can range, for example, from 0.1% to 10% by weight relative
to the total weight of the composition, and preferably from 0.5% to
5% by weight.
[0015] A variety of waxes may be present in the mascaras of the
present invention, including waxes of animal origin, waxes of plant
origin, waxes of mineral origin and waxes of synthetic origin.
Examples of waxes of animal origin include beeswaxes, lanolin waxes
and Chinese insect waxes. Examples of waxes of plant origin include
rice waxes, carnauba wax, candellila wax and ouricurry wax, cork
fibre waxes, sugar cane waxes, Japan waxes, sumach wax and cotton
wax. Examples of waxes of mineral origin include paraffins,
microcrystalline waxes, montan waxes and ozokerites. Examples of
waxes of synthetic origin include polyolefin waxes, e.g.,
polyethylene waxes, waxes obtained by Fischer-Tropsch synthesis,
waxy copolymers and their esters, and silicone waxes.
[0016] Alternatively, hydrogenated oils of animal or plant origin
may be used. Examples include hydrogenated jojoba waxes and
hydrogenated oils which are obtained by catalytic hydrogenation of
fats composed of a C.sub.8-C.sub.32 linear or nonlinear fatty
chain, hydrogenated sunflower oil, hydrogenated castor oil,
hydrogenated copra oil, hydrogenated lanolin and hydrogenated palm
oils. The waxes are preferably solid and rigid at temperatures
below 50.degree. C.
[0017] Generally, wax content of washable mascaras ranges from
about 0 to about 50% by weight, and preferably from about 10 to
about 45% by weight of the mascara composition. Wax content of
waterproof mascaras generally ranges from about 0 to about 40% by
weight, and preferably from about 5 to about 35% by weight of the
mascara composition.
[0018] The fibers useful in the present invention may be chosen
from natural and synthetic fibers. Natural fibers include, but are
not limited to, cotton, silk, wool, and other keratin fibers.
Synthetic fibers include, but are not limited to, polyester, rayon,
nylon and other polyamide fibers.
[0019] Yet other fibers useful in the present invention include
those described in EP 1172078. The fibers disclosed in this
publication include types of elastofibers. These fibers are
chemical fibers, extremely stretchable, and which regain their
primary shape as soon as the tractive force is interrupted.
Representative examples include elastane (abbreviations: EL or
Spandex.RTM.)), highly polymerized fibers, which contain at least
85% by weight of segmented polyurethane, and elastodiene fibers
(abbreviation: ED) containing synthetic polyisoprenes or high
polymers, which are obtained from the polymerization of one or more
dienes, by optionally adding one or several vinyl monomers. Rubbery
fibers (abbreviation: LA) issued from natural rubber may also be
included in the second group. The elastodienes are often
vulcanized. A fiber composed of both polyamide and polyurethane
also has elastic properties.
[0020] The fibers, may, for example, be present in the washable
composition, the waterproof composition, or in both compositions,
and may be the same or different. The fibers are present in an
amount generally ranging from about 0.1% to about 20% relative to
the total weight of the composition. In some embodiments, the
fibers are present in an amount ranging from about 0.2% to about
10% relative to the total weight of the composition. The fibers
typically have an average length ranging from about 0.5 mm to about
4.0 mm, such as from about 1.5 mm to about 2.5 mm.
[0021] The composition according to the invention may additionally
comprise a film-forming polymer which can be solubilized and/or in
the form of particles in dispersion in the aqueous phase. The
film-forming polymer can be selected from keratin derivatives, such
as keratin hydrolysates and sulphonic keratins; anionic, cationic,
amphoteric or nonionic derivatives of chitin or chitosan; cellulose
derivatives such as hydroxyethylcellulose, hydropropylcellulose,
methylcellulose, ethylhydroxyethylcellulose,
carboxymethylcellulose, and quaternized derivatives of cellulose;
acrylic polymers or copolymers, such as polyacrylates or
polymethacrylates; polyvinylpyrrolidones (PVP) and vinyl
copolymers, such as methyl vinyl ether-maleic anhydride copolymers,
or vinyl acetate-crotonic acid copolymer; water-dispersible anionic
polyesteramide and/or polyester polymers comprising monomers
bearing a functional group--SO.sub.3M, in which M represents a
hydrogen atom, an ammonium ion NH.sub.4.sup.+ or a metal ion, such
as, for example, an Na.sup.+, Li.sup.+, K.sup.+, Mg.sup.2+,
Ca.sup.2+, Cu.sup.2+, Fe.sup.2+ or Fe.sup.3+ ion. Specific examples
of the polymers described in U.S. Pat. Nos. 3,734,874, 4,233,196
and 4,304,901. Polyurethane polymers, especially anionic, cationic,
nonionic or amphoteric polyurethanes, acrylic polyurethanes,
polyvinylpyrrolidone polyurethanes, polyester polyurethanes,
polyether polyurethanes, polyureas, polyurea/polyurethanes, and
mixtures thereof; and polymers of natural origin, modified if
desired, such as gum arabic, guar gum, xanthan derivatives, karaya
gum; alginates and carragheenates; glycoaminoglycans, hyaluronic
acid and its derivatives; shellac, sandarac gum, dammars, elemis
and copals, are also useful. The film-forming polymer can be
present in the mascara compositions in an amount of dry matter
generally ranging from about 0.1% to about 20% by weight relative
to the total weight of the mascara composition.
[0022] Preferred film-formers include combinations of a first tacky
film former soluble or dispersible in water, and a second tacky
film former soluble in oil. For purposes of this invention, the
term "soluble or dispersible in water" means that the substance in
question will not precipitate out or coagulate, e.g., that it
dissolves up to the limit of saturation. The term "soluble in oil"
means "miscible in oil"; in other words, if a substance is not
soluble in oil, it is immiscible, forming distinct layering in the
oil phase, an indication that the substance is not compatible or
soluble in the oil phase. For purposes of this invention, "tacky"
is defined as sticky or adhesive to the touch. The combination of
tacky film formers may allow, in at least some embodiments, one or
more of the following to occur: allow the fibers to adhere to the
eyelashes, allow optimal water resistance and allow minimal
flaking.
[0023] Examples of the at least one tacky film former soluble or
dispersible in water include polyvinyl alcohols (such as the AIRVOL
series from Air Products); polyvinyl acetates (such as FULATEX (R)
sold by H.B. Fuller Co.); cellulose acetate phthalate aqueous
dispersions (such as AQUACOAT CPD sold by FMC Corp.); and acrylates
copolymers, such as DAITOSOL 5080 AD sold by Kobo Products,
vinylpyrrolidone/acrylates/lau- ryl methacrylate copolymers (such
as STYLEZE 2000 sold by ISP), acrylates/C.sub.1-2
succinates/hydroxyacrylates copolymers (such as ALLIANZ LT-120 sold
by ISP), PVP/DMAPA acrylates copolymers (such as STYLEZE CC-10 sold
by ISP), and crosslinked poly (2-ethylhexyl acrylates) in water
(such as GEL-TAC 100 series sold by API). In one embodiment, the at
least one tacky film former soluble or dispersible in water is
chosen from an acrylates copolymer and polyvinyl acetates. The at
least one tacky film former soluble or dispersible in water is
present in the mascara composition in an amount of dry matter
generally ranging from about 0.1% to about 20% relative to the
total weight of the composition. In some embodiments, the at least
one tacky film former soluble or dispersible in water is present in
an amount ranging from about 1% to about 15%, relative to the total
weight of the composition. In yet other embodiments, the at least
one tacky film former soluble or dispersible in water is present in
an amount ranging from about 1% to about 10%, relative to the total
weight of the composition.
[0024] The at least one tacky film former soluble in oil is
preferably chosen from hydrogenated polyisobutenes, adipic
acid/diethylene glycol/glycerin crosspolymers (such as that sold as
LEXOREZ 100 by Inolex), polyethylenes, and polyvinyl laurates. In
some embodiments, the at least one oil-soluble tacky film former is
chosen from hydrogenated polyisobutenes. Hydrogenated
polyisobutenes are available from, for example, Collaborative
Laboratories, East Setauket, N.Y., under the name POLYSYNLANE. In
some embodiments, the hydrogenated polyisobutenes to be used in the
claimed invention have a weight average molecular weight of greater
than 1500. In other embodiments, the hydrogenated polyisobutenes
have a weight average molecular weight greater than 2000 and in yet
other embodiments, they have a weight average molecular weight
greater than 3000. The at least one tacky film former soluble in
oil may, for example, be present in the composition in an amount
generally ranging from about 0.5% to about 30%, relative to the
total weight of the composition. In some embodiments, the at least
one tacky film former soluble in oil is present in the composition
in an amount ranging from about 1% to about 20%, relative to the
total weight of the composition. In yet other embodiments, the at
least one tacky film former soluble in oil may be present in the
composition in an amount ranging from about 1% to about 15%,
relative to the total weight of the composition.
[0025] The mascara compositions of the invention may contain
emulsifying surfactants. Surfactants can be selected from
amphoteric, anionic or nonionic surfactants. See, e.g.,
Encyclopedia of Chemical Technology, KIRK-OTHMER, volume 22, pp.
333-432, 3rd edition, 1979, Wiley, for the definition of the
properties and (emulsifying) functions of the surfactants, in
particular pp. 347-377 of this publication regarding anionic and
nonionic surfactants. Examples of surfactants useful in the mascara
compositions of the invention are include as nonionic surfactants,
fatty acids, fatty alcohols, polyethoxylated fatty alcohols or
polyglycerolated fatty alcohols, such as polyethoxylated stearyl
alcohols or cetylstearyl alcohols, esters of fatty acid and
sucrose, and glucose alkyl esters, in particular polyoxyethylenated
C.sub.1-C.sub.6 alkyl glucose fatty esters, and as anionic
surfactants, C.sub.16-C.sub.30 fatty acids neutralized by amines,
ammonia or the alkali metal salts thereof. Examples of amphoteric
surfactants include betaines, sultaines, hydroxysultaines, alkyl
amphodiacetates, alkyl amphodipropionates, and imidazolines, or
salts thereof. Other fatty acid condensates such as those formed
with amino acids, proteins, and the like are suitable as well.
Specific examples include cocamphodipropionate, e.g., Miranol
C2M-SF (disodium cocamphodipropionate), in its salt-free form,
available from Rhone-Poulenc, and Crosultaine C-50 (cocamidopropyl
hydroxysultaine), available from Croda.
[0026] In washable mascaras, surfactants are selected in order to
obtain an oil-in-water emulsion. Preferred examples include
triethanolamine and stearic acid. In waterproof mascaras,
surfactants are often used to facilitate dispersion of pigments.
Preferred examples include lecithins. Lecithins are mixtures of
phospholipids, i.e., of diglycerides of fatty acids linked to an
ester of phosphoric acid. Preferably, lecithins are diglycerides of
stearic, palmitic, and oleic acids linked to the choline ester of
phosphoric acid. Lecithin is usually defined either as pure
phosphatidyl cholines or as crude mixtures of phospholipids which
include phosphatidyl choline, phosphatidyl serine, phosphatidyl
ethanolamine, phosphatidyl inositol, other phospholipids, and a
variety of other compounds such as fatty acids, triglycerides,
sterols, carbohydrates, and glycolipids. See, e.g., U. S. Pat. Nos.
6,015,574 and 6,221,389. Lecithins may also be present in washable
mascaras. Surfactants are generally present in amounts ranging from
about 2 to about 30% by weight, and preferably from about 5% to
about 15% by weight, relative to the total weight of the mascara
composition.
[0027] The composition of the invention may additionally comprise
ingredients that are commonly used in cosmetics, such as
plasticizers, coalescence agents, fillers, dyestuffs, such as
pigments or dyes, preserving agents, oils, cosmetic agents, such as
moisturizers and anti-UV agents vitamins, trace elements,
softeners, sequestrants, perfumes, oils, silicones, proteins,
ceramides, cohesion agents, and the basifying or acidifying agents
that are commonly employed in the cosmetics field.
[0028] Pigments include organic, white or colored, and coated or
uncoated particles. Among the mineral pigments which may be useful
are titanium dioxide, optionally surface-treated, zirconium oxide,
zinc oxide or cerium oxide, as well as iron oxide, chromium oxide,
manganese violet, ultramarine blue, chromium hydrate and ferric
blue. Among the organic pigments that may be useful is carbon
black, pigments of D&C type, and lakes based on cochineal
carmine or on barium, strontium, calcium or aluminium. For example,
these organic pigments may include D&C Red No. 7 Calcium Lake,
D&C Red No. 21 Aluminum Lake, FD&C Yellow No. 5 Aluminum
Lake, and FD&C Blue No. 1 Aluminum Lake. The at least one
pigment of the invention may be chosen from the above and any other
pigment or treated pigment known in the cosmetic arts. The at least
one pigment may also be chosen from pearling agents, such as, for
example, mica, iron oxides, titanium dioxide and any other pearling
agent known in the cosmetic arts. The mascara compositions may
contain at least one pigment in an amount generally ranging from
about 0.5% to about 15% by weight relative to the total weight of
the composition. In some embodiments, the at least one pigment is
present in an amount ranging from about 1% to about 12% by weight
relative to the total weight of the composition.
[0029] In terms of fillers, silica is particularly useful to obtain
a thicker make-up effect on the eyelashes. Starches such as rice
starch, talc and polytetrafluoroethylene are highly compatible with
aqueous medium and allow a smooth, shiny film of make-up to be
obtained. Fillers are generally present in the mascara compositions
in an amount of about 0.1% to about 6% by weight relative to the
total weight of the mascara composition.
[0030] In addition to the foregoing teachings, examples of specific
washable and waterproof mascara compositions are legion in the
prior art. See, e.g., U.S. Pat. No. 6,264,933 for examples of
waterproof mascaras, and U.S. Pat. No. 5,985,258 for examples of
washable mascaras.
[0031] The methods of the present are practiced simply by applying
to the eyelashes the washable mascara, followed by applying the
waterproof mascara. The waterproof mascara may be applied
immediately after application, but generally anytime from about 30
seconds to about 10 minutes after application of the washable
mascara.
[0032] With reference to FIGS. 1-3, the mascara compositions of the
invention may be provided in a mascara product or system comprising
two reservoirs, each of which contains one of the mascara
compositions, and applicators for applying each of the compositions
to the eyelashes. This mascara product or system may be
conveniently packaged in a variety of forms. As best shown in FIG.
1, one example of such preferred packaging includes a blister pack
10. The reservoirs 14 and 16 are housed in the blister pack 10,
which comprises translucent plastic material (not shown) attached
to a cardboard substrate backing 12. The backing may be generally
rectangular in shape. Any shape that is capable of preventing any
direct handling of the products by customers is contemplated and
within the scope of the present invention. See, e.g., U.S. Pat. No.
6,378,727.
[0033] Each reservoir 14 and 16 is positioned within the blister
pack 10, preferably in a side-by-side manner. Each reservoir
includes corresponding applicator portions 18 and 20, which are
discussed below in detail.
[0034] The reservoirs typically are provided with an opening 15, 17
that accommodates a liquid-removal (or applicator) system. As best
seen in FIG. 2, the applicator portions 18, 20 typically comprise a
rod 22, 24 equipped at a first end with an applicator member 26, 28
such as a brush, and at a second end with a handle component 30, 32
that acts as both a means for manipulating the applicator by the
user, and as a cap for closing the reservoir, preferably in a
leak-tight manner (e.g., the handle component itself is configured
to close the reservoir).
[0035] The applicator member 26, 28 preferably comprises bristles
34, 36 arranged radially around a twisted core 38, 40, such as a
metal core. The brush can be of varied shapes and can comprise
cutout sections. Mascara brushes are described, for example, in
French Patent Application No. FR-A-2,607,373 and European Patent
Application Nos. EP-A-611,170, EP-A-811,336, EP-A-811,337 and
EP-A-842,620.
[0036] The respective applicator members 26, 28 may be the same or
different. In some embodiments, they are different. For example,
application of the washable mascara may be facilitated with a
relatively full and soft brush 34. An example of such a brush is
described in U.S. Pat. No. 4,887,622. The disclosed brushes include
a central core formed by a twisted iron wire holding a helical
array of radial bristles in a regular manner characterized by the
fact that the bristles have a diameter between about 0.10 and about
0.25 millimeters (mm), and the number of bristles per turn being
between about 10 and about 40.
[0037] A preferred example of an applicator member 28 for applying
waterproof mascara is described in U.S. Pat. No. 4,993,440. The
brushes disclosed in this patent contain a central elongate core
around which are implanted bristles disposed in a substantially
radial fashion and regularly distributed. Each bristle 36 of at
least one portion of the brush comprises on its surface at least
one capillary channel (not shown) extending substantially from its
base as far as its tip. Preferably, all the bristles of the brush
have capillary channels. The brush is evenly charged and a
homogeneous distribution of the mascara on the eyelashes is
achieved. Further, the systems and packages of the present
invention may further contain indicia such as directions or
instructions (e.g., printed information) for using the mascara
compositions.
[0038] Alternate embodiments of mascara systems are shown in FIGS.
3A and 3B. In FIG. 3A, the reservoirs 14 and 16 are integral with
each other, e.g., their respective bottom or side surfaces are
fastened together in some manner. In another alternate embodiment
shown in FIG. 3B, one applicator 50 is provided, which contains a
single handle component 18' and two stems 22, 24 oppositely opposed
from the handle component, wherein each stem has an applicator
member 26, 28 at its opposite end. The handling component contains
a cap configured to close each of the reservoirs, preferably in a
leak-tight manner.
[0039] The present invention is further described in terms of the
following non-limiting examples. Unless otherwise indicated, all
parts and percentages are on a weight-by-weight basis.
