DE2318868C2 - Device for applying a hair dye - Google Patents

Description

The invention relates to a device for applying a hair colorant to human hair with a color wax block containing the hair colorant, which has at least two edge surfaces with essentially straight edges that can be used for applying color wax to the hair and which can be used in a container with at least one opening , due to the soft edge of the colored wax block protruding when applied to the hair
One of the major difficulties with dry hair dye applicators is the uneven wear of the material during use. This combines an even coloring of the hair, especially where the hair is divided and the uncolored hair roots are unpleasantly visible. For coloring the uncolored, exposed hair roots, an application material with an elongated edge which can be applied in the area in which the hair is divided is desirable. In known devices for applying non-liquid hair dyes, the part that can be applied wears out quickly and unevenly, so that most of the dye device becomes unusable.

For the application of dry paint (as opposed to applicators for liquid paint) in the

«US-PS 27 85 693 suggested the use of a comb which consists entirely of a mixture of pigments with stearic acid and thinning fillers With this construction, the comb wears itself out during use, and so does the cross-section the prongs become so small over time that they break off and the comb also loses its effectiveness combs were provided with an overall wedge-shaped pastel pencil (US-PS 17 07 665), in which the pastel pencil in a chamber formed by the comb itself

so sits With the wear and tear of the pastel color, the areas of application of paint between the prongs become more and more more of the comb teeth surrounding them, so that the uncolored hair roots become more uncomfortable Way to remain free. The colored pencil cannot be moved outwards to reveal the receding colored areas compensate or replace.

Application devices according to US Pat. No. 28 18 167 have the disadvantage that they do not have multiple pages and their edges for application. Several

Edges and corners on the colored wax block make it easier to identify while the product is being kneaded quickly become dull with a single surface. The same applies to the application device according to the US-PS24 77 245.

In DE-AS 21 37 788 of the applicant, although a hair Adftragvorrichtung was described, which characterized by an open area along a block of wax, the several elongated and substantially

has continuous paint application surfaces that run lengthways this face of the block are spaced from each other. Still, there is another improvement desirable in order to increase the usefulness and safety of hair dyeing devices since also here after a certain period of use the applicability of the colored wax block is limited. the end British Patent 5,37,600 is an apparatus to apply lip red or eyebrow directions are used dszu to the color wax block in the desired direction, which is given by slots in one wall of the container, v ^ rzuscWe ben. Df, ii, it the user has the w ^ hI between eint. Number of well-defined edges from a number of different surfaces for applying the color wax Hui the hair.

Further advantages and refinements of the invention emerge from the subclaims. Using the in

In one embodiment of FIG. 7A, a comb 66 is attached to the applicator, namely just as in the embodiment of FIG. 7 the brush. The prongs 6? of the comb 66 separate the hair and also expose areas of hair in different strokes when the wax is applied. Fig. 7B shows an exemplary embodiment that has both a Brush 60 -Is also has a comb 66

The in Fig. The embodiment of the color wax application device shown in FIG. 8 contains a box or a container 70 with a front and rear side 71 and 72, which are connected to one another by four pins or supports 73 arranged at the corners. The sides 74 are all open so that the color wax block 75 can be pushed out through each of the sides 74. In FIG. 8, the block 75 has been pushed out of the top of the box 70. The front side 71 is provided with a vertical slot 76A and a horizontal slot 76 which intersect in the central area. A clamping screw 77 (Fig. II) with a knurled button 78 and a shaft 79, which resembles the clamping screw 29 except for the missing mushroom-shaped part 33, is screwed through the intersecting slots 76/4 or 76 into a nut 80 which is embedded in the color wax block 75. The clamping screw 77 and the colored wax block 75 are similar to the embodiment of FIG. I. In the embodiment of FIG. 8, however, the raised or mushroom-shaped part 33 on the screw shaft is unnecessary, since the block 75 is not as in FIG. 1 needs to be rotated, generally in the embodiment of Figure 8 a clamping effect of the clamping screw in the released position is not required

In the embodiment of FIG. 8, the color wax block 75 cannot be rotated. Rather, he can go out each of the four open sides or ends 74 of the box can be slid out. This is done through Loosen the clamping screw 77 and move the block up, down, right or left in one of the intersecting slots 76-4 or 76. If the color wax block 76 is one desired for application Position reached, the clamping screw 77 is tightened, whereby the block 75 firmly and securely against the Wall 71 is clamped and secured to apply the color to the hair. For storage in the withdrawn Position the clamping screw 77 is only loosened and the block 75 in the middle position of the Box 70, where the clamping screw is tightened again so that it holds the block 75 against the lower one The surface of the wall 71 is stuck

According to FIG. 9, the color wax block 75 can be easily removed from the box 70 by removing the wall 72 which is opened in the closed position by the cooperating parts of hooks or tabs 81 are clamped. It can be any simple locking means can be used to hold the wall 72 in place. You can by means of attached to a hinge or completely removable. The embodiment shown here remains the nut 80 in the box 70. However, the screw 77 is normally unscrewed and the Nut 80 remains in recess 82 of block 73. Block 75 and nut 80 are unscrewed the screw 77 removed. The refill unit consists of the wax block 75 and one unit in this embedded nut 80.

The embodiment of Figures 8 and 9 can there

be modified by that the side 72 is rigidly attached to the four corner supports. The wax block 75 can then replaced by unscrewing the clamping screw 77 and removing the wax block 75 from one of the open Ends 74 is pushed out. The refill unit can be pushed into the container in the same way and the nut 80 can be brought under one of the slots. The clamping screw 77 is then screwed in and the colored wax block 75 fastened in the box 70. It can then be detached and in be moved in one of the four directions.

10 shows a box 85 that is the box 70 the F i g. 8 and 9 are similar except that they are square and contain a square block of wax 86.

The nut 80 is embedded in the wax block 86 of FIG. 10. It is shown alone in FIG. 11, without the box 85 shown. The clamping screw 77 is unscrewed from the nut 80. Wax block 86 and nut 80 can be easily removed from the applicator. The block 86, with the nut 80 embedded in it, represents a refill unit.

Fig. 12 shows a further embodiment with a triangular wax block, which differs from that of the 1, 2 and 3 differ in that a triangular box 90 is also used. Except for the triangular shape and the slot arrangement resembles the box 90 that of FIGS. 8, 9 and 10 perpendicularly the edges of the box run in the front 94 intersecting slots 91, 92 and 93. The Clamping screw 95 can be pushed forward to one of the three edges after it has been released, so that the colored wax block 18 protrudes from one of the three open ends.

In use, the applicator is held in the hand and moved with the brush 50 or 61 or the comb 67 or with brushes 50, 61 and comb 67 through the hair. The color wax is applied to the hair under pressure, the same colored in the desired shade will. Looking at the color wax blocks 18 and 18Λ of Fig. 1, it can be seen that the triangular block 18 has nine edges 99. The square block ISA has twelve well-defined edges 98. Each of these edges offers the user a relatively well-defined paint application surface, so that the hair can be colored very close to the roots by brushing the edge against the hair under pressure to apply the color wax to the desired extent. This means that many edges are available to the user, in contrast to application devices in which only one surface can be exposed for use

As the wax wears off over time, the clamping screw 29 can be loosened somewhat and the block advanced outwardly, exposing additional area while the clamping screw 29 is slid along the slot and tightened in the desired position. When the exposed edge areas that protrude from the open end of the box are worn and rounded and blunt, the wax block can be rotated for further use, as shown in the exemplary embodiment in FIGS. 1 was explained.
In the exemplary embodiments of FIGS. 8 to 12, if necessary, well-defined edges can be obtained if the clamping screw is loosened and advanced into a position in which one other side of the wax block with its four edges comes from another

open ends of the box protrudes. Is the colored wax block worn so far that it will be replaced can, the clamping screw is unscrewed, the used block is removed and replaced with a new one. Alternatively, the box and pad can be viewed as a unit and thrown away if that Wax is used up.

The colored wax block preferably consists mainly of stearic acid or a derivative thereof, Candelwla wax with beeswax, some car-

10

nauba wax and the coloring material carefully mixed in it. Instead of candelilla wax you can use paraffin or another suitable wax can be used.

The proportions to be used can be in terms of content and components are changed. It is important that the coloring material is safe for humans and non-toxic and does not irritate the scalp. The mixture is expediently bactericidal and / or fungicidal Properties bestowed.
