Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an ornamental wig such as a
toupee or a hairpiece that can change a color thereof principally
in response to the existence of a light irradiation such as an
ultraviolet ray.
[0003] 2. Descriptions of the Related Art
[0004] In recent years, especially among young men and women,
changing their hair color to brown, yellow, red and so on has been
in fashion. In this hair color change, his or her own hair, for
example, black hair is decolorized and dyed in other favorite
colors. Some time later, when his or her hair grows, since the
new-growth portion of the hair coming out of a scalp is black, its
color difference relative to the dyed hair portion is conspicuous.
As a result, the new-growth portion must be decolorized and dyed
again. Accordingly, additional cost and labor are required
therefor, and the hair itself is subject to damage. Although there
is another method for changing the hair color, in which the hair is
dyed with an exclusive dye, a similar problem occurs since the live
hair is used in this method as well.
[0005] On the other hand, there have been toupee and hairpiece used
as imitation hair. Among them, there have been ones subjected
initially to a dyeing treatment and coloring. However, each of
these imitation hair pieces has a single color, and there has been
no imitation hair that can change its color to other colors.
[0006] As described above, both the natural and imitation hair
pieces require troublesome treatment such as decolorization and
dyeing for changing their color, and the color change can not be
easily performed. Accordingly, hair that can change its color
instantaneously has not been known up to the present.
SUMMARY OF THE INVENTION
[0007] The present invention was made with the foregoing problems
in mind. The object of the present invention is to provide an
ornamental wig such as a toupee or a hairpiece, which does not
require a special treatment in a specialty store such as a hair
parlor and can easily change its color in response to light
irradiation such ultraviolet ray radiation and or upon a change in
temperature.
[0008] In order to solve the foregoing problems, an ornamental wig
according to the present invention comprises reversible
photosensitive discoloring imitation hair containing a photochromic
compound at least in a portion thereof, in which the wig is of a
size to be attachable to a human head, and an attaching means is
fitted to a portion of the wig.
[0009] Note that, an hair ornamental wig is preferably constituted
of a polyolefin fiber that contains an organic photochromic
compound having a molecular weight of 300 or more, and further,
according to needs, contains a pigment and wax series
dispersant.
[0010] Moreover, the imitation hair may be constituted by combining
reversible photosensitive discoloring imitation hair and reversible
thermosensitive discoloring imitation hair.
[0011] Furthermore, the imitation hair may change its color
entirely or partially.
[0012] Still further, the attaching means preferably has an
ornament portion, a hairpin portion and an imitation hair fitting
portion.
[0013] Still further, the ornament portion has an engaging portion
with the hairpin portion freely detachable, and the attaching means
and the imitation hair may be freely detachable from each
other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] In FIG. 1, a reference numeral 1 generally denotes an
ornamental wig. The wig 1 is constituted such that attaching
devices 4 are attached to a net-shaped base member 3 having hair 2
implanted therein. The hair 2 is imitation hair made of a synthetic
resin (fiber) or a regenerated resin (fiber). The wig 1 has a size
set so as to be attachable to a person's hair.
[0034] The wig 1 is not limited to a wig that covers all of a
person's hair. As shown in FIGS. 2A and 2B, the wig 1 may be such
as to only partially cover a person's. These partial wigs 1 also
have the imitation hair 2 implanted on the base members 3 (not
shown in FIGS. 2A and 2B).
[0035] Moreover, as more fashionable wigs, the following are
exemples: a wig in which the ornamental imitation hair 2 is fitted
to a tip end of a pin 5 (clasp-cum-base member) as shown in FIG.
3A; a wig in which the ornamental imitation hair 2 is fitted along
a long rubber member 6 (clasp-cum-base member) as shown in FIG. 3B;
and a wig in which the ornamental dummy hair 2 is fitted to an
ornament portion 10 of a hairpin 4 as shown in FIG. 3C. As such
types of wigs, other than the ones exemplified as described above,
there are various types of the wigs I such as a braid type, a
long-hair type, a chignon type, a screw type, a twist type and a
zigzag type.
[0036] As described above, the imitation hair 2 may be fitted to
the base member 3 in any manner, and the fitting manner is not
limited to implanting. Moreover, the base member itself is not
limited to a planar member. For example, the base member may be a
belt-shaped member, or each of a member combined with the attaching
device or devices such as the base member of each of FIGS. 3A and
3B. Furthermore, the attaching device or devices 4 do not have any
limitation, in particular, and may be freely selected from a
hairpin, an America pin, a comb, a barrette, a rubber member
(ring-shaped or string-shaped), a string, a wire, a net and the
like can be freely selected.
[0037] The imitation hair 2 used in the wig 1 is a reversible
photosensitive discoloring hair that changes its color with a light
irradiation of an ultraviolet ray and the like as described later,
and changes a certain color thereof to another color by irradiating
a light thereon.
[0038] The imitation hair 2 may be uniformly changed in color over
its entirety, or only partially changed in (i.e., with only a
portion thereof changed in color). In the case where the entire
imitation hair 2 The color of the entire imitation hair 2 that is
initially shown may be changed to another color. Alternatively, the
color of a portion that is initially shown differently from another
portion may be changed to the other color of the entire imitation
hair 2 together with the other portion. On the other hand, in the
case where the color of the imitation hair 2 is partially changed,
as shown in FIG. 4A, groups of the imitation hair 2 that change
their colors respectively may be made to exist in such a manner
that small numbers of the hair groups are mixed with each other so
that the entire imitation hair 2 can look like the hair having a
single color by changing the respective colors. For example, it is
conceived that red hair and white hair are mixed so that the mixed
hair can look pink. And, in addition to the red and white colors
being obtained by changing the other colors, the portion of the
white color is left so as not to change its color, but the red
color of the other portion may be obtained by changing the other
color. Moreover, as shown in FIG. 4B, groups of the imitation hair
2 having different colors from each other may change their colors
while each group is collected to some extent. In this case, the
groups of the imitation hair 2 may change their colors only
partially with the light irradiation of the ultraviolet rays and
the like though they have a single color initially. Alternatively,
the groups of the imitation hair 2 that have different colors
initially may change their colors to another uniform color.
Furthermore, as shown in FIG. 4C, the imitation hair 2 may change
its color for each portion. In this case, a striped pattern may be
formed with the light irradiation of the ultraviolet ray or the
like. For example, the imitation hair 2 having entirely a striped
pattern may be obtained by changing the color of a predetermined
portion thereof having initially the same color as other portions
by irradiating the light. Alternatively, the imitation hair 2
having a striped pattern initially may be changed to one that has
another striped pattern having a different color from the original
color with the light irradiation of the ultraviolet ray or the
like.
[0039] Herein, as the imitation hair 2 used for the wig 1, a fiber
material having a feature of containing a photochromic compound can
be listed. The photochromic compound is a substance that has a
function of changing a color reversibly with a light having a
specified wavelength such as the ultraviolet ray. As such a
photochromic compound, any compound can be used as long as it has
been conventionally known as a photochromic compound. The
photochromic compound is not subjected to particular
limitations.
[0040] As examples of the photochromic compound, the following can
be listed: an azobenzene series compound, a thioindigo series
compound, a dihydrobromide series compound, a spiropyran series
compound, a naphthopyran series compound, a benzopyran series
compound, a spirooxazine series compound, a silver series compond
and the like.
[0041] On the other hand, as the fiber material, various types of
synthetic fibers and regenerated fibers can be listed.
[0042] By containing such a photochromic compound, the imitation
hair 2 of the present invention has a reversible photosensitive
discoloring function of changing the color of the imitation hair 2
by irradiating the light such as the ultraviolet ray and returning
the changed color to the original color by stopping the
irradiation.
[0043] Incidentally, as a more preferable constitution of such
imitation-hair having the reversible photosensitive discoloring
property, a polyolefin fiber that contains an organic photochromic
compound having a molecular weight of 300 or more can be listed.
This polyolefin fiber has a good processing property, a low
toxicity to a human body, the low toxicity being essential for such
an application, and a low possibility of generating a toxic
substance such as a dioxin due to burning after being discarded. As
such, the polyolefin fiber has various advantages. However, since
the polyolefin fiber itself does not typically have a polarity,
when it is made to contain a substance having a polarity such as
the photochromic compound, a blooming phenomenon occurs. For this
reason, the present invention was made in an attempt to solve such
a problem as the blooming phenomenon by selectively using an
organic photochromic compound having a molecular weight of 300 or
more.
[0044] Herein, the organic photochromic compound implies an organic
compound among the foregoing photochromic compounds. As long as the
organic photochromic compound has a molecular weight of 300 or
more, the type thereof does not matter. However, it is particularly
preferable to use at least a type of the compound selected from
among a spiropyran series compound, a naphthopiran series compound,
a benzopyran series compound and a spirooxazine series compound,
which have high coloring density during the light irradiation and
are rich in color types.
[0045] Specifically, the following can be listed:
[0046] (1)
1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl)-spiro[2H-indole--
2,3'-[3H] naphtho[2,1-b] [1,4]oxazine] (molecular weight 411);
[0047] (2)
6'-(2,3-dihydro-1H-indole-1-il-1,3-hydro-1,3,3-trimethylspiro[2-
H-indole-2,3'-[3H]naphtho[2,1-b] [1,4]oxazine] (molecular weight
445);
[0048] (3)
1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl)-4-(triple-ole-me-
thyl)spiro[2H-indole-2,3'-[3H]naphtho[2,1-b] [1,4]oxazine]
(molecular weight 479);
[0049] (4)
1,3-dihydro-1,3,3,4,5-pentamethyl-spiro[2H-indole-2,3'-[3H]naph-
tho[2,1-b] [1,4]oxazine] (molecular weight 356);
[0050] (5) 3,3-diphenyl-3H-naphtho[2,1-b] pyran (molecular weight
334); and
[0051] (6) 6-methoxi-2,2-diphenyl-2H-1-benzopyran (molecular weight
314).
[0052] On the other hand, as the polyolefin fiber, any
conventionally known polyolefin fiber can be used, and the
polyolefin fiber is not subjected to any limitation. A wide range
of fibers, for example, the polyolefin fiber, a polypropylene
fiber, an ethylene-propylene copolymer fiber and the like can be
employed. Note that these fibers may be partially bridged fibers.
Alternatively, the fibers may be fibers in which acrylonitrile,
(meta-) acrylic acid, (meta-) ester acrylate, vinyl acetate,
styrene, vinyl chloride, vinylidene chloride and the like are
copolymerized or singly compounded.
[0053] Moreover, since the above-described organic photochromic
compound typically exhibits discoloring between a solid color and a
chromatic color in many cases, various types of pigments may be
compounded in the concerned polyolefin fiber for the purpose of
further enriching color variation thereof and so on. In this case,
it is preferable to use a dispersant in order to increase
dispersibility of the pigments in the fiber, and it is particularly
preferable to use a wax type dispersant that does not inhibit the
discoloring property of the above-described photochromic
compound.
[0054] As examples of the pigments, the following can be listed:
organic pigment, inorganic pigment, fluorescent pigment, luminous
pigment, pearl pigment, metallic pigment, gold powder, silver
powder, glass powder, thermochromic capsule pigment, a microcapsule
containing perfume and the like. However, the pigments are not
limited to the above examples.
[0055] Moreover, as examples of the wax type dispersants, a
polyethylene wax, a polypropylene wax, a paraffin wax, an amide
wax, a wax, a carnauba wax, a microcrystalline wax and the like can
be listed. However, the wax type dispersants are not limited to the
above examples.
[0056] As a method of manufacturing the imitation hair of the
present invention constituted of the reversible photosensitive
polyolefin fiber as described above, any conventionally known
method may be employed, and the manufacturing method is not
subjected to any limitation. For example, the above-described
respective components are previously classified in a color palette,
or directly mixed with a polyolefin resin as a fiber forming
polymer, and then fusing and spinning are performed by use of a
fusing/spinning apparatus. Thus, the reversible photosensitive
polyolefin fiber can be obtained. Moreover, in this case, by
varying a shape of a spinneret, a spinning speed, a drawing
magnification or the like, the reversible photosensitive polyolefin
fiber having various cross-sectional shapes (for example, circular
shape, oval shape, star shape, triangular shape and gear shape) and
various sizes (for example, 0.1 to 500 .mu.m) can be obtained.
[0057] Note that the imitation hair of the present invention can
contain various conventionally known additives other than the
above-described components according to desires.
[0058] As examples of the additives, the following can be listed:
ultra-violet ray absorbent; optical stabilizer; filler; dye;
fluorescent dye; electrochromic agent; liquid crystal; ultraviolet
ray emitting type coloring matter; perfume; flame retardant; flame
proofing agent; deodorizer; antimicrobial agent; antiseptic;
fungicide; repellent; and light catalyst. However, the additives
are not limited to the above-described examples.
[0059] Moreover, as examples of the imitation hair of the present
invention other than the above-described examples, conjugate series
imitation hair of a center/sheath type that contains an organic
photochromic compound in a center thereof can be listed (see
Japanese Patent Laid-Open No. Hei 4-202811).
[0060] Next, a method of attaching the wig of the present invention
will be described below. For example, when the wig 1 shown in FIGS.
3A and 3B is attached, it is recommended that a hair portion 7 be
bundled in a dumpling shape at a side portion of the head as shown
in FIG. 5A or a high position of the head as shown in FIG. 5B or be
shaped in a pony-tail. Then, the imitation hair 2 is attached to
the person's natural hair by the attaching device 4 on devices.
When the wig 1 of FIG. 3A is attached to the natural hair of FIG.
5A, the result shown in FIG. 6A appears. When the wig 1 of FIG. 3A
is attached to the hair of FIG. 5B, the result shown in FIG. 6B
appears. In any case, although the wig may be attached so as to be
identified purposely, the base of the wig 1 may be preferably
hidden with the hair, a bandanna, a turban or the like. Naturally,
two or more types of the wig may be combined and attached to the
natural hair.
[0061] Furthermore, the wig shown in FIG. 3C will be described in
detail below. The attaching device shown in FIG. 3C has an ornament
portion, a hairpin portion and an imitation hair fitting part. As
shown in FIG. 3D, the imitation hair is fitted between the ornament
portion and the hairpin portion in a winding manner, as shown in
FIG. 3D, and is fixed by simple engaging member such as a rubber
band. Moreover, the imitation hair may be fixed by the engaging
member as shown in FIG. 3E, or naturally may be fixed with adhesive
or the like.
[0062] Moreover, the hairpins as shown in FIGS. 3F and 3G have been
conventionally available. In order to fit the imitation hair to
these hairpins, the engaging member 9 with the hairpin portion may
be provided in the ornament portion as shown in FIG. 3F so as to
make the imitation hair freely detachable. Furthermore, when the
hairpin 10, shown in FIG. 3G, is used, the imitation hair may be
wound around the hairpin portion to be engaged with the rubber band
or the like similar to that described above.
[0063] When light having a specified wavelength such as the
ultraviolet ray is irradiated to the wig 1 after the wig 1
manufactured with the imitation hair 2 constituted as described
above is attached to the head of a wearer, the imitation hair 2
changes its color to blue, red, yellow, green, etc. And when the
light irradiation stops, the color is returned to the original
color. As described above, since the color of the imitation hair 2
is changed only by irradiating the light such as the ultraviolet
ray, the color of the imitation hair 2 of the wig 1 is changed
between the cases, for example, where the wearer goes outside from
the inside of a building and the imitation hair 2 receives
sunlight, and where the wearer comes inside the building from the
outside. Because of this color change, the impression of the wearer
given to others is changed, thus the wearer can change his/her
image during a day.
[0064] Moreover, since the color of the wig 1 is automatically
changed without any special care or treatment, handling thereof is
very easy.
[0065] Furthermore, since the trouble of performing any special
treatment to the imitation hair in a specialty store such as a
beauty parlor can be eliminated and the imitation hair can be
easily discolored in response to the existence of the light
irradiation such as the ultraviolet ray, the imitation hair is low
in cost and is convenient.
[0066] Still further, since the hair of the wearer is not directly
subjected to the dyeing treatment, the hair cannot be damaged.
[0067] Still further, as shown in FIG. 7, by use of the wig 1 by a
child, he or she can obtain a sense of unity with his/her mother or
a doll 8 changing its hair color. Specifically, if the color of
his/her mother's hair is green, the child may use the wig 1, the
original color or the changed color of which is green.
Alternatively, if the color of the doll's hair is changed from pink
to green, the child may attach the wig 1 changing his or her color
similarly. In such a manner, the child can feel a sense of unity
with his/her mother or the doll.
[0068] Still further, a portion of the imitation hair 2 can change
its color reversibly from a certain color to another color upon a
change in temperature. Specifically, the imitation hair 2 may be a
combination of the reversible photosensitive discoloring imitation
hair that changes its color depending on the existence of the light
irradiation such as the ultraviolet ray and the reversible
thermosensitive discoloring imitation hair that changes its color
depending on the temperature change.
[0069] In this case, as the thermosensitive discoloring substance,
for example, as disclosed in U.S. Pat. No. 3,560,229, a composite
having a combination of an electron impartable colorable compound
(leuco coloring matter) and an electron receivable developer
(phenol group and the like) as a base and a three-component series
composite obtained by adding organic solvent to the above-described
two components can be listed. Moreover, in Japanese Patent
Publication No. Sho 62-28990, a thermosensitive discoloring
substance having these composites encapsulated in so-called
microcapsules is disclosed. Such a thermosensitive discoloring
substance can also be preferably used. And, these thermosensitive
discoloring substances are uniformly mixed with the polyolefin
resin, the polypropylene, polyamide and the like, and the mixture
is subjected to extrusion forming a filament-shaped body. Thus, the
reversible thermosensitive discoloring imitation hair can be
manufactured (see Japanese Patent No. 2519484, Japanese Patent
Publication No. Sho 51-37180 and so on).
[0070] It is preferable that a portion that is the reversible
thermosensitive discoloring imitation hair changes its color to
blue, green, yellow, red and so on when the temperature of the
imitation hair rises to a predetermined temperature by heating it
with a device such as a hair dryer. The discolored state is held
for a while after stopping the heating. Thereafter, when the
temperature of the imitation hair is lowered to below a
predetermined temperature, the color returns to the original color
again. Note that, if a thermosensitive discoloring substance that
changes its color at about body temperature is used, the discolored
state can be maintained while the wig 1 is attached to the wearer's
head. Naturally, the foregoing pigments can be added to the
reversible thermosensitive discoloring imitation hair depending on
the purpose of enriching the color variation and so on.
[0071] By combining the reversible photosensitive discoloring
imitation hair and the reversible thermosensitive discoloring
imitation hair, a certain portion of the imitation hair changes its
color depending on the existence of the light irradiation such as
the ultraviolet ray, and another portion thereof changes its color
depending on the temperature change. Accordingly, a complicated
color change can be enjoyed.
[0072] Also in this case, the color can be easily changed at a low
cost, and since the natural hair of the wearer is not directly
subjected to the discoloring treatment, the hair cannot be damaged.
As such, an effect similar to the case of the reversible
photosensitive discoloring imitation hair can be obtained.
[0073] Thus, according to a first aspect of the present invention,
when the light such as the ultraviolet ray is irradiated to the wig
attached to the hair of the wearer by the attaching device or
devices, the color of the imitation hair is changed. And when the
light irradiation stops, the color returns to its original color.
In such a manner, the color of the hair is changed only by
irradiating with the ultraviolet ray. Accordingly, the color of the
wig hair is changed between the case where the wearer goes outside
from the inside of a building such that the wig receives sunlight,
and the case where the wearer comes inside the building from the
outside. Because of this color change, the impression of the wearer
given to others is changed, and thus he or she can change his/her
image during a day. And, since the color is changed by irradiating
the light, no special tool or apparatus is required, and the color
of the ornamental wig is automatically changed without any special
care or treatment. Accordingly, handling thereof is very easy.
[0074] Furthermore, since the trouble of performing special
treatment of the imitation hair in a specialty store such as a
beauty parlor can be eliminated and the imitation hair can be
easily discolored in response to the existence of the light
irradiation such as the ultraviolet ray, the imitation hair is low
in cost and is convenient.
[0075] Still further, since the natural hair of the wearer is not
directly subjected to the dyeing treatment, the hair cannot be
damaged.
[0076] According to a second aspect of the present invention, the
imitation hair can have a good processing property, low toxicity to
the human body and a low possibility of generating a toxic
substance. Moreover, there is no fear that the organic photochromic
compound will bloom in the concerned imitation hair.
[0077] According to a third aspect of the present invention, since
the pigment can be favorably dispersed without adversely affecting
the organic photochromic compound, the imitation hair can be rich
in the color variation.
[0078] According to a fourth aspect of the present invention, by
combining the reversible photosensitive discoloring imitation hair
and the reversible thermosensitive discoloring imitation hair, a
complicated color change can be enjoyed.
[0079] According to a fifth aspect of the present invention, since
the color of the entire imitation hair is changed, the changed
color is conspicuous and the impression of the entire hair can be
greatly changed.
[0080] According to a sixth aspect of the present invention, since
the color of the partial imitation hair is changed, a subtle color
change can be enjoyed.
[0081] According to a seventh aspect of the present invention,
since the wig has the attaching device or devices, the ornament
portion, the hairpin portion and the imitation hair fitting
portion, the wig can be easily attached to the head, and does not
become as exaggerated as a conventional toupee, and the cost
thereof is low. Moreover, since the imitation hair is attached by
one or more small engaging members such as a rubber band, the
engaging member(s) is inconspicuously hidden in the imitation
hair.
[0082] According to an eighth aspect of the present invention,
since the ornament portion and the imitation hair are set freely
detachable, the ornament portion and the imitation hair can be
easily fitted to the conventional hairpin. Accordingly, a novel
hair ornamental wig can be provided.
