Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a dry-color applicator for the human hair
which may be used by men and women safely and inexpensively and
more particularly to an applicator which permits the use of all
available edges of an applicator.
2. Prior Art
One of the major problems with dry-color applicators is the uneven
wearing away of the dry applicator material with use. This
prohibits even coloring of hair especially in the region where the
hair is parted and where uncolored hair roots embarrassingly show.
In order to color uncolored exposed hair roots, a well-defined,
elongated edge of applicator material is desirable which can be
applied into the region where the hair is parted. In prior art
devices where non-liquid hair coloring was applied, the applying
portion wore down rapidly and unevenly, thereby precluding the use
of the majority of such coloring means.
In the design of dry-color as distinguished from liquid
applicators, it has heretofore been proposed (Bova, U.S. Pat. No.
2,785,693) to utilize a comb made entirely of a mixture of pigments
with stearic acid and diluent fillers. In such a construction the
comb itself decreases in dimensions during use, and the teeth soon
become of such small cross-sectional area as to break and lose
their effectiveness. Combs have also been provided with a stick of
crayon, generally wedgeshaped, as in Julien, U.S. Pat. No.
1,707,665, where the crayon fits within a compartment formed by the
comb itself. As the colored crayon wears away, the color-applying
surfaces between the teeth recede and move farther and farther away
from the comb teeth that surround it, embarrassingly leaving
exposed uncolored hair roots. There is no possibility here of
movement of the crayon outwardly to compensate for the receding
coloring areas.
Applicators such as disclosed in McKinley, U.S. Pat. No. 2,818,167
have the disadvantage of not providing multiple sides and their
edges for application. It will be understood that multiple edges
and corners of the block of coloring wax fully facilitate its
application whereas the edges of a single surface product as in
McKinley quickly become blunt. The same holds true for the wax
applicator disclosed in Pischel et al, U.S. Pat. No. 2,379,745 and
the hair applicator of Giddings et al, U.S. Pat. No. 2,477,245.
Though in my U.S. Pat. No. 3,640,288, I have disclosed a hair
applicator characterized by the provision of an unobstructed face
along a block of wax which has a plurality of elongated and
substantially continuous colorapplying surfaces in spaced relation
one from the other along that face of the block, nevertheless, the
subject invention is a desirable improvement in increasing utility
with safety to the consumer for hair coloring devices.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the subject invention to provide a
dry-color hair applicator as opposed to the bottled variety on the
market; a dry color applicator which is perfectly safe for use by
the consumer and free from the toxicity and poisonous liquid hair
colorings which can lead to blindness to say nothing of other
injuries.
It is another object of the subject invention to provide a
dry-color hair applicator which is protected in a container that is
compact, easy to pocket, easy to use, and which at the same time
also protects the user's hands and clothing from unwanted, smeary
wax deposits.
It is yet another object of the subject invention to provide a
dry-color hair applicator in which multiple sides and edges can be
readily exposed for use allowing the user to have an unblunted edge
as needed and which is so necessary to effectively transfer the
coloring wax to root areas of the hair.
Another object of the subject invention is to provide a dry-color
hair applicator in which the container is reuseable and the wax
product may be easily replaced, when and as desired.
Yet another object of the subject invention is to provide a
dry-color hair applicator with fixed or detachable brush and comb
attachments for use, singly or together or not at all, as desired.
The brush or teeth of the comb may, when the hair is stroked with
the coloring wax, facilitate the efficiency of the hair coloring
operation.
In accordance with the subject invention, there is provided an
open-ended enclosure or container for a multi-sided block of hair
coloring wax. In the past, dry-coloring hair applicators have not
provided the consumer with a multiple number of well defined edge
areas which are desirable to color root areas of the hair. In one
preferred embodiment, the block of coloring wax which may be
triangular, or of other suitable geometric configuration, any
number of sides of which are rotatable within said container so
that succeeding sides with their edges and corners may be aligned
with the open end of the container and projected therethrough at
will to provide the consumer with well-defined color-applying
surfaces. The wax block may be easily rotated by means of a
thumbscrew which is inserted into a receiving member, preferably a
nut, secured within the block of coloring wax. The screw in the
above mentioned form, extending through a surface of the container
enables the rotation of the block along with providing clamping
action to lock the wax block firmly in position for application or
storage.
In another preferred embodiment, the enclosure is provided with a
plurality of open ends or sides through which the block of wax may
be propelled for color application to the hair. Thumb-screw means
are utilized to push the coloring wax block in the desired
direction as permitted by slots in a wall of the enclosure. Thus,
the consumer has at his or her disposal a number of welldefined
edges from a number of different surfaces for applying the coloring
wax to the hair.

DETAILED DESCRIPTION
With reference now to the drawings, as shown in FIG. 1, the
dry-color applicator comprises an enclosure 10 having an upper
portion 11 and a lower portion 12 made of any suitable material
such as metal, plastic, or both.
Upper 11 and lower 12 portions are connected by means of a standard
compact-type hinge 13 in which circular extensions 14 and 15 of
lower portion 12 and extension 16 of upper portion 11 pivots about
pin 17, as best seen in FIG. 2 (upside down view of applicator of
FIG. 1). Open end 19 as seen best in FIG. 2 of the container 10
allows a block 18 of coloring wax to protrude outwardly for
application to the hair. In FIG. 1, the open end of the container
10 is shown covered by flap 20 which pivots about pin member 21 to
bottom face surface 22 of container 10 when the applicator is in
use. Any suitable means such as a small clasp or spring means (not
shown) may be used to hold flap 20 in its open position.
As shown in FIG. 1, upper portion 11 has a face area 23 with a
sidewall section 24. Sidewall 24 has knubs 25 which when the upper
portion or lid 11 is closed, lock into depressions 26 of bottom
portion sidewall 27.
In face area 22 of bottom portion 12 there is an elongated slot 28
extending in a direction transverse of open end 19 through which
slot thumb-screw 29 comprising a knurled thumb knob 30 and a
central shaft 31 is insertable. The thumb-screw 29 is threadably
received by a receiving member shown as nut 32 which is secured in
block 18 of wax. Thumb-screw 29 and nut 32 may be made out of
metal, plastic, or other suitable material.
As seen most clearly in FIG. 1, an enlarged or mushroomed portion
33 on the bottom of the thumb-screw 29 is designed to bear against
nut 32 when thumb-screw 29 is unthreaded a couple of turns. This
will cause thumb-screw 29 to lock thus enabling the rotation of the
block 18, in which nut 32 is embedded. Block 18 may thereby be
rotated without the need of the user physically touching it.
Thumb-screw 29 may be threaded into nut 32 to the extent that thumb
knob 30 will bear against the bottom wall of 22 of container 10, as
viewed in FIG. 1, serving to hold wax block 18 firmly in place for
application to the hair. When thumb-screw 29 is loosened, slot 28
provides a pathway for the screw 29 to be moved toward and from
open end 19 for driving the wax block 18 along the slotted
structure to project out of the open end 19 for application or
returned back into container 10 for storage. Thumb-screw 29 may be
tightened anywhere along the slot as desired to provide clamping
action that will hold the coloring wax from unwanted movement
against container bottom 22.
As shown in FIG. 1, the coloring wax block may be triangular 18,
square 18A, or may be of other suitable geometric configuration.
Nut member 32 is secured in recessions 32A of the wax block 18 or
18A.
While enclosure 10 of FIGS. 1 and 2 is shown as essentially
curvilinear with a flat side, the container may be of any suitable
shape as long as its dimensions are sufficient to allow the wax
block 18 to rotate within. The compactness of the article may be
appreciated by the following dimensions.
By way of example only, if a standard size ladies' compact of 23/4
inches in diameter is used as the container size, a chord slightly
greater than 21/4 inches in length may be extended across a portion
of the circular container which represents the open-flat end 19.
Into such a container can be placed an equilateral triangular block
18 of wax 21/4 inches per side or a square block of coloring wax
18A, 13/4 inches per side. Dimensions such as these, while not to
be considered limiting, present an accurate idea of the
surface-applying area of a wax block which may be exposed for
application to the hair.
With reference to FIG. 3, a modification of container 10 of FIGS. 1
and 2 is shown. Container 40 is a permanently closed container not
having the upper and low separable portions of container 10. A slot
41 which may be considered to be in either the top or bottom face
of the container 40, extends from the central region of face 42 to
the flat-sided-open-ended side 43. A flat coloring wax block 18A is
shown being held in place by thumb screw 29. In this embodiment,
the block 18A can be easily replaced by loosening screw 29 and
removing screw 29 and block 18A from container 40 by sliding them
out. A new block of wax 18A or 18 may be inserted and clamped in
place by tightening the screw 29 in the new block of coloring wax.
It is clear that for propelling the coloring wax outwardly for
instant use, that a turn of the screw 29 in one direction releases
the clamping action and a second turn in the opposite direction
locks the coloring wax in place. The block of coloring wax 18A may
then be rotated in the manner described for the block of FIG. 1 by
unthreading thumb screw 29 to the extent permitted so that the
mushroomed portion 33 bears against the bottom of nut 32 preventing
screw 29 from turning relative to nut 32 which when the thumb knob
is rotated will cause the block 18 or 18A to be rotated. Care must
be taken when the screw 29 is unlocked to not let block 18A slip
from container 40, the screw 29 sliding out slot 41.
Referring to FIG. 4, thumb screw 29 is shown with its knurled thumb
knob 30 clamped in place against surface 42. This causes the block
of wax 18A to be locked in place, and as shown with portion 44
extending out of container 40 at open end 43. It will be noted in
this position that raised area or mushroomed portion 33 at the
bottom of screw shank 31 is not bearing against bottom surface 45
of nut 32.
FIGS. 5 and 6 show enlarged portions of FIG. 4 with brush
attachments. Also screw shanks 31 are shown without the raised
portion 33 which locks upon bottom surface 45 of nut 32. This
enables the screw 29 to be completely unthreaded from the nut 32
and removed therefrom. In this type of embodiment, the replacement
unit might comprise a block of coloring wax with a nut embedded in
it, the screw 29 remaining with the container member 10 or 40 as
the case may be.
In FIG. 5, brush member 50 is shown permanently affixed to
container 40. It is also to be noted that the brush member 50
extends below block of wax 18 or 18A.
In FIG. 6, brush member 50 is affixed within holder 51 which is
inserted in groove 52 of container sidewall 53. The brush
attachment thus can be readily removed for storage by sliding
element 51 laterally along and then out of the groove 52. In this
Figure, the wax block 18A is shown adjusted to extend below brush
member 50 and as can be appreciated it may be used either above or
below or coextensive with brush member 50.
As shown in FIG. 7, a hinged-brush attachment may be used. Brush
attachment 60 having bristles 61 is pivotally connected to wall
member 63 by pin 65 at knob area 64. The bristles extend lengthwise
along the open end 43 of container 40 to stroke the hair so the wax
is pressure-applied by a stroking and brushing action. The wax may
be applied with the brush in its downward position, or it may be
applied without the brush when the brush is in the raised position
as shown by the dotted lines in FIG. 7.
A comb attachment 66 is shown attached to the applicator of FIG. 7A
in the manner of brush attachment 60 of FIG. 7. The comb attachment
66 has teeth 67 which serve to separate the hair and expose
additional hair areas on different strokes as the wax is applied.
Both brush 60 and comb 66 attachments are shown mounted on opposite
sides of container 40 in FIG. 7B.
With reference to FIG. 8, the color applicator embodiment shown
therein comprises an enclosure or container 70 having front and
rear faces 71 and 72 connected by four posts or dowels 73
positioned at the corners. The sides 74 are all open allowing the
coloring wax block 75 to be projected outwardly through any of the
sides 74. In FIG. 8, the block 75 is shown projecting out of the
top side of container 70. Front face member 71 has a vertical slot
76A and a horizontal slot 76 which intersect in the central region.
A thumb-screw 77 (as shown in FIG. 11) with knurled knob 78 and
shank 79 and otherwise like thumb-screw 29 of preceding
modifications except for the absence of mushroomed portion 33 is
inserted through intersecting slots 76A or 76 and threaded into nut
80 which is embedded in wax block 75. The thumb-screw 77 and wax
block 76 combination is similar to the embodiment shown in FIG. 1.
However, the need for the raised end 33 on the screw shank is
eliminated in the FIG. 8 embodiment, since block 75 does not have
to be rotated as in FIG. 1 since in FIG. 8 the rotating function of
the thumb screw in an unclamped position is not required.
As can be appreciated from the configuration of th embodiment of
FIG. 8 the wax coloring block 75 is not rotatable, but rather may
be projected outwardly of any of the four open sides or ends 74.
This is done by loosening thumb screw 77 and propelling it up and
down or right or left in either of intersecting slots 76A and 76
which respectively extend transversely of the side openings. When
coloring wax block 75 reaches a position desired for application,
thumb screw 77 is tightened, clamping block 75 firmly in place
against wall 71 to secure it for hair coloring application. For
retracted storage, thumb screw 77 is simply loosened and the block
75 is brought to the central portion of container 70 where the
thumb-screw is tightened once again, clamping block 75 against the
under surface of wall 71.
As shown in FIG. 9, wax coloring block 75 may be easily removed
from container 70 by opening wall member 72 which is locked in a
closed position by mating parts of clasp 81. Any type of simple
closure device may be used to hold member 72 in place and it may be
hinged or completely removable. The nut 80 is shown as remaining in
container 70, however, normally in this embodiment the screw 77
will be unscrewed leaving nut 80 in recession 82 of block 75 and
the block 75 and nut 80 will be removed together once the screw 77
is unthreaded. A refill portion may comprise the block of wax 75
and embedded nut 80 as a unit.
The embodiment of FIGS. 8 and 9 may be modified by having member 72
rigidly secured to the four corner posts 73. The block of wax 75
would then be replaced by unthreading thumb screw 77 and sliding
the wax block 75 out of one of the open ends 74. A refill unit may
be slid into the container by the same means and the nut portion 80
will be placed underneath one of the slots and thumb screw 77
screwed in place to secure block of wax 75 within container 70
which may then be loosened for movement of the coloring wax in all
four directions as desired.
With reference to FIG. 10, an enclosure 85 is shown which is
identical to enclosure 70 of FIGS. 8 and 9 except that it is square
in configuration and has a square wax block 86.
The wax block 86 with embedded nut 80 of FIG. 10 is shown in FIG.
11 as being removed from container 85. Thumb screw 77 is unthreaded
from nut 80 to permit the ready release of wax block 86 and nut 80
from the applicator, the block 86 with embedded nut 80 representing
a replacement unit.
As illustrated in FIG. 12, another embodiment utilizes a triangular
wax block 18 yet differs from the embodiment of FIGS. 1, 2, and 3
in that a triangular enclosure or container 90 is also used which
otherwise may be like the containers of FIGS. 8, 9, and 10 except
for the triangular shape and slot configuration. Intersecting slots
91, 92, and 93 in front face 94 are disposed perpendicular to the
container edges and permit thumb screw 95 when loosened to be
propelled toward any of the edges causing coloring wax block 18 to
be projected out any of the three open ends.
In use, the applicator is held in the hand and is moved through the
hair with the brush 50, 61, or comb 67, or with both brush 50, 61
and comb 67, if used. The coloring wax presented by a peripheral
side is pressure deposited on the hair to color the same to the
desired shade. Observing the wax blocks 18 and 18A of FIG. 1, it
will be noted that the peripheral side of triangular block 18 have
nine edge portions 99. It will be seen that the four peripheral
sides of square block 18A have twelve edge portions 98, the edges
being well defined. Each of these peripheral edge portions present
the user with a relatively well-defined color-applying surface
which gives him or her the ability to color hair substantially
close to the roots by pressure stroking the edge against the hair
to apply the coloring wax as desired. Thus, from the many edges of
the plurality of peripheral sides the user gets advantages lacking
in dispensers where only one surface can be exposed for use.
As the wax begins to recede with use, thumb screw 29 may be
loosened slightly and the block may be propelled outwardly to
expose additional area while the screw 29 is slid along the slot
and tightened at the desired fixed position. As the exposed edge
areas, which are extending from the open end of the container, wear
down and become rounded and blunt, the block of wax may be rotated
for extended use as described with respect to the embodiment of
FIG. 1.
In th embodiments of FIGS. 8-12 well-defined edges may be obtained
when needed by loosening the thumb screw and projecting it to a
position where another peripheral side of the wax block with its
four edges projects from another of the open-ends of the enclosure.
When the block of coloring wax has been used sufficiently to
warrant replacement, the thumb screw is unthreaded and the used
block removed and replaced by another. Alternatively, the enclosure
and block may be considered a unit and discarded when the wax is
used.
While other formulations may be utilized, it is preferred that the
block be made with its primary ingredient either stearic acid, a
derivative of it, candelilla wax with beeswax, some carnauba wax
and the desired coloring material thoroughly mixed therein. In
place of the candelilla wax, paraffine or other suitable wax may be
used.
The proportions to be utilized may be varied in proportion and
ingredients. It is essential that the coloring material be harmless
to human beings and lacking in toxicity or scalp-irritant
properties. It will be desirable to include in the mixture
anti-bacterial and/or anti-fungal properties.
A preferred composition will be as follows:
Triple Pressed Stearic Acid 40 lbs Paraffine 45 lbs Beeswax 10 lbs
Carnauba Wax 5 lbs Dry Color to suit (see below) One and a half
percent of an anti-fungal, anti-bacterial substance having an 80
percent cationic activity consisting of 68 percent stearyl dimenthy
benzyl ammonium chloride and the balance in related cationics; such
as is to be had in Triton X-400 made by Rohm and Haas.
The examples of differing coloring materials are as follows:
For red heads or brunettes, red 12 lbs ochre, burnt sienna, Tuscan
red may be used as pigment. For bond color, one can use as 12 lbs
the pigment golden ochre, yellow ochre, chrome yellow among others.
Titanium Oxide mixed with Zinc 15 lbs Oxide for silver grey and
salt and pepper color. For black hair: Carbon black as desired up
to 61/2 lbs
Having now described several embodiments of the invention, it will
be understood that many variations may be made without departing
from the invention as set forth by the claims. For example, the
particular shapes and configurations of the block of coloring wax
and its container are not critical, as long as the wax block has
more than one peripheral side portion for pressure coloring the
hair.
