Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a device for penetrating the active ingredient contained in a preparation into hair.

[0002]

BACKGROUND OF THE INVENTION It is generally common to treat hair with the active ingredients contained in its preparations, either for cleaning or care purposes, or for cosmetic reasons. Thus, under the term "preparation", any medium that is applied to obtain a defined action on the hair is understood. This includes cleaning agents (or shampoos), hair care agents, waxes, oils, media for modifying the structure of the hair (such as Haarglaettungsmittel or permanents) and used to improve combing. So-called “surface smoother”. Furthermore, the term "preparation" is used to describe media for dyeing or bleaching hair as well as so-called "finished products", i.e. hair penetrants, hair fixatives or media that give the impression of wet hair (so-called "wet gels"). ).

[0003] Generally, such preparations are applied to the hair using a hand, brush or sponge, or as a spray. In this case, only a relatively small amount of the active ingredient penetrates into the interior of the hair, whereas the majority of the active ingredient contained in the preparation merely deposits on the surface of the hair.
Under the influence of water, the sun or other environmental factors, the effectiveness of the preparation is rapidly diminished since the superficially deposited active ingredient is easily exfoliated or decomposed. Nevertheless, in order to obtain a hair treatment effect which lasts long enough, the active ingredients must be used in high dosages. Such overdosage of the active ingredient, on the other hand, is costly.
On the other hand, high active ingredient dosages can lead to hair damage in some cases.

[0004] In addition, the application of dyes has the disadvantage that, due to the superficial dye application, the dyed hair has a different light refraction from natural hair of comparable shades. . Dyed hair often gives the observer a matte or dull impression, which is immediately perceived as unnatural.

[0005]

The object of the present invention is therefore to make it possible to increase the effectiveness of preparations containing the active ingredient,
It is an object of the present invention to provide a device for penetrating an active ingredient into hair.

[0006]

In order to solve this problem, the present invention provides two lever arms crossed in the form of a tongue, each of which has one press at its working end. A roller is supported and the press roller is rotatable about a substantially parallel axis, and the press roller presses against the operating end of the lever arm to release the hair to be treated with the preparation. The area of the outer peripheral surface for applying a pressure can be pressed against each other.

[0007]

With respect to the method, the object is solved by an arrangement according to the invention as set forth in the characterizing part of claim 1. In this case, two press rollers which are rotatable about substantially parallel axes are provided, which can be pressed against one another in the region of their outer peripheral surface in order to generate mechanical pressure. In this case, the hair to be treated is guided between press rollers (like a slab used for pressing steel). The press rollers are each mounted on two intersecting lever arms in the form of tongs for operation at the working end.

[0008] The active ingredient is therefore penetrated into the hair using external pressure. In this case, the pressure to be applied clearly exceeds the natural load on the hair, which can be created, for example, by air pressure or head massage. This pressure is, for example, the effect of DE-A-362 362.
It also exceeds the clamping force of a static hair clip for loading hair with a treatment liquid, which is known from U.S. Pat.

[0009] While it is possible in principle to carry out the application of the preparation and the pressure treatment as two method steps separated in time, it is also possible to apply the preparation to the hair already under pressure. . Rolling under pressure increases the amount of active ingredient that penetrates into the hair in any case. The porous hair fibers absorb more of the preparation surrounding the hair in the form of a sponge when the pressure drops. Instead of applying the preparation only superficially as when using known hair clips, the hair is infiltrated with an increased amount of preparation after pressure treatment.

In this case, the active ingredient which has penetrated into the interior of the hair is not only protected to a considerable extent by washing and, for example, by degradation by sunlight,
This active ingredient is further distributed throughout the volume of the hair fiber,
Thereby, the effect can be fully exhibited. If a dye is used, the pigment as an active ingredient penetrates into the hair cortex located below the surface of the hair due to pressure treatment. This cortical layer also contains the natural pigments of the hair. Thereby, the hair dyed by the pressure treatment retains its natural light refraction.

The compression of the hair fibers near the surface results in good combing, especially with the use of a surface smoother. In this case, the disadvantageous burden on the hair is largely avoided. Similarly,
Even when using "finished products", the hair is somewhat sealed against harmful environmental effects. The improvement obtained is comparable to the improvement obtained by high pressure infiltration of wood over standard wood protective coatings.

The device formed as a press tong advantageously has a particularly simple mechanism for applying mechanical pressure to the hair which can be guided between the press rollers. The production of this preston is therefore possible with little cost. Furthermore, no special prior knowledge is required to operate this device and thus to carry out the method. Due to the enhancing effect of the lever arm, it is possible to easily apply a sufficient high pressure for hair treatment by hand.
In this case, the hair is only loaded laterally, that is to say in a direction perpendicular to the direction in which it extends, due to the rotatable rollers. Longitudinal pulling of the hair, which causes pain to the customer, is largely avoided. The remaining tension due to the roller resistance of the press roller can be used to penetrate the wavy hair with the smoothing agent through the device and at the same time elongate the hair.

It is advantageous if the press roller is fitted at right angles to the working end of the lever arm, so that the axis of the press roller lies substantially perpendicular in the plane of intersection of the lever arm. This simplifies the operation of the device.
Furthermore, in this arrangement, the axis of the press roller always occupies the same angle, irrespective of the position of the lever arm. This in particular ensures that the pressure applied by hand is always evenly distributed over the entire length of the roller.

The at least one press roller, but preferably each press roller, is provided with a peripheral wall made of a resilient material, in particular of a rubber-like or foam-like material, so that the hair is particularly good in the roller material. Embedded in This does not crush the hair. Rather, a sufficiently uniform pressure is applied over the entire circumference of the hair. The characteristics of the peripheral wall material are advantageously selected variously in relation to the altitude of the peripheral wall, the absorbing power, etc., depending on the purpose of use.

If this device is used with viscous dyes, it is particularly advantageous to provide a relief-like surface structure on the outer peripheral surface of at least one press roller. In other words, if the outer peripheral surface of the press roller is smooth, a considerable part of the preparation is displaced in front of the press roller like a crest. The relief-like surface structure, the generally protruding shape, the recesses or the grooves enhance the adhesion of the preparation on the surface of the press roller.

If a circumferentially extending annularly closed recess is used as the surface structure, an advantageous embodiment of the invention provides that
It is easily possible to dye so-called "combed hair tresses". The "combed hair bundle" is a thin dyed hair bundle, which is positioned next to an uncolored hair bundle so as to form a streak pattern alternately. I have.

A pair of rollers provided with a relief-shaped surface structure is formed so that the surface structure of the corresponding roller is formed to have a complementary shape, that is, each of the protrusions provided on the surface of one roller. Can be further improved if they are positively engaged with corresponding recesses in the surface of the other roller. In this way, the pressure is distributed particularly uniformly over the length of the roller.

For special purposes of use (that is, use of a given preparation), a pair of press rollers is provided, each of which is particularly well suited for the purpose of use in relation to its properties. Have been combined. Accordingly, press rollers for different purposes of use differ in properties such as surface hardness and radius of curvature. Further, the surface structure, absorbency, and length of the press roller can vary. In addition, it is advantageous to use one unique pair of press rollers for different shades. In order to replace the press roller without having to replace the entire device, the press roller is advantageously detachably connected to the working end of the lever arm. In this case, it is advantageous to use a connection that is easily and quickly released. For example, a snap connection or a bayonet connection is suitable.

In order to obtain, on the one hand, optimization in view of the particular application and, on the other hand, to obtain as good a pressing as possible when using a large number of different preparations, an advantageous embodiment is used. Means are provided for adjusting the pre-defined pressing force according to the intended use. In this case, the pressure to be used is advantageously controlled in relation to the preparation. It is advantageous, if additionally or alternatively, for the pressure to be variable in relation to the properties of the hair to be treated.

The maximum pressure used can be limited particularly simply by providing in the edge region of each press roller a spacer disk of a hard material which is coaxial with this press roller. Similarly, it is also possible to attach a stopper or a ratchet-type locking connection as a pressure limiting member to the lever arm. A pressure-limiting member of this type is known, for example, as a tong-shaped end insulation for electrical cables. Of course, it is also possible to provide a mechanical or electric pressure gauge.

It is advantageous if at least one press roller with a drive is provided. This avoids tension that would cause the customer to feel the hair at the hairline when the hair is pulled by the roller pair. This drive is performed mechanically, for example, via a crank. For the professional use of this device, the operation is greatly simplified by the provision of an electric drive. Particularly in the case of an electric drive, it is advantageous to use a means configured as a torque clutch in case of inadvertently applying too much tension to the hair.

In many preparations, it is advantageous to assist the pressure treatment by additionally supplying heat.
This, on the one hand, can promote the swelling of the hair. This facilitates penetration of the active ingredient into the interior of the hair. On the other hand, the heat promotes the chemical reaction of the active ingredient in the hair, for example during bleaching. In some cases, it is also advantageous to dry the hair with heat during the pressing operation. Therefore, by incorporating a heating device inside at least one of the press rollers, a process combining pressing and heating can be particularly easily performed.

To further facilitate the penetration of the preparations present in the preparation into the hair, the application and the pressure treatment of the preparations can be carried out in a single application, also with a configuration adapted for professional use. Can be combined in stages. For this purpose, a container for the preparation is provided in at least one press roller, which is connected to a discharge opening distributed over the outer circumference of the press roller.
Numerous variations are possible. It is advantageous if at least one press roller is surrounded by a trough-shaped housing casing. With a housing of this type, such as is known on the basis of ink rollers in painting, it is possible to avoid the hassle of dripping of the preparation from the press rollers. In this case, such a storage casing can be configured such that the stored preparation is automatically entrained by a press roller and fed back to the hair.

It is also conceivable to connect a number of pairs of press rollers one after another. This is advantageous if different pairs of press rollers are specified for different tasks. Thus, for example, means for applying the preparation to the first pair of press rollers can be provided, whereas the heating device can be accommodated in the second pair of press rollers. Similarly, a comb can be pre-connected to the pair of press rollers. In such an arrangement, the hair is neat and evenly stretched by the pair of press rollers. Irregular pressure distribution due to the presence of thick knots in the treated hair bundle is avoided. Combs in combination with a hair smoothing agent provide an additional smoothing effect in the pressure treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to embodiments shown in the drawings.

FIG. 1 shows a device configured as a preston 1 for penetrating the active ingredient into the hair. This device 1 comprises two crossed lever arms 2
And 3. The lever arms 2 and 3 are supported in the form of a tongue (Zangen) at their intersection so as to be pivotable with respect to one another about a common lever axis 4. A single press roller 7 or 8 is rotatably attached to the working ends 5 and 6 of the lever arms 2 and 3, respectively. The axes 9 and 10 of the press rollers 7 or 8 are arranged parallel to each other. Moreover, these axes 9, 10 extend parallel to the lever axis 4. In other words, the axes 9 and 10 lie perpendicular to the plane of intersection of the lever arms 2 and 3.

In order to carry out the treatment shown in FIG. 1 using the reduced preston 1, the preparation is first applied to the hair in a conventional manner. For this purpose, for example, a brush is used. The bundle of hair is then split and introduced into the gap S formed between the press rollers 7 and 8, generally near the hairline. By pressing the operating ends 11 and 12 of the lever arms 2, 3 against each other manually, the press roller is brought into its loaded position (not shown). The press rollers 7 and 8, which guide the bundle of hair between these rollers like slabs or rolled steel, are then rolled over the entire length of the hair. As mentioned above, the operation of the device and the comfort for the customer are greatly simplified by an electric or mechanical drive, advantageously as a schematically shown motor (M). Or improved. A motor (M) of this type can be mounted in an advantageous manner on the press rollers 8, 9 or on the lever arms 2, 3. Furthermore, at least one of the press rollers (7, 8) has a heating device (not shown, for example in the form of an electric heating coil).

FIG. 2 shows a variant of the device which is particularly suitable for viscous liquids, for example dyes. In this case, projections 15 for forming a relief-shaped or relief-shaped surface structure are provided on the outer peripheral surfaces 13 and 14 of the press rollers 7 and 8. Due to the embossed or rough surface structure, the viscous preparation is more strongly bonded to the surface of the press rollers 7,8. The pressing of the viscous preparation by the press rollers 7, 8 is therefore performed only on a small scale, as in the case of a Bugwelle. The same effect can of course be obtained by other three-dimensional surface patterns (for example, grooves). The press rollers 7, 8 shown in FIG. 2 have a substantially star-shaped cross-sectional shape, as shown in FIG. The press rollers 7, 8 have a hollow cylindrical roller core 16, which is rotatable relative to the lever arms 2, 3, in order to realize a bearing in which the press rollers 7, 8 can rotate. It concentrically surrounds a shaft 17 which is immovably (that is, rotates together). The roller core 16 is again surrounded by a peripheral wall 18. This peripheral wall 18 is advantageously made of an elastic material.

As the press roller 8 approaches the press roller 7 in the travel stroke L, the press roller 8 is brought into the load position for the press roller 7, shown schematically in FIG. The axis 10 and the outer peripheral surface 14 of the press roller 8 at the load position are indicated by reference numerals 8 'or 10' or 14 '. As shown in FIG.
The outer peripheral surface 14 ′ of the roller 8 ′ is engaged with the outer peripheral surface 13 of the roller 7 in a form-locking manner.

FIG. 4 shows a press roller with an embossed surface structure which is particularly suitable for forming a so-called "combed hair bundle". For this purpose, the press roller has a recess 19 closed in a circumferential direction around the outer peripheral surface 13 of the press roller 7. Thereby, according to the longitudinal sectional view of the press roller 7 shown in FIG. 4, a comb having teeth on both sides is formed. Some of the recesses 19 are filled with dye to form a combed hair bundle. The hair tress is then guided in a conventional manner between a roller 7 and a press roller 8 (not shown) with a corresponding surface structure. The combed hair bundle introduced into the dye-filled recess 19 in a kind of streak pattern by pressing the rollers 7 and 8 against each other and rolling the rollers 7, 8 over the hair bundle. As the dye is colored on the hair.

In a preferred embodiment of the press rollers 7, 8 shown in FIG. 5, a predetermined maximum pressure is set when the press rollers 7, 8 are pressed together. At this time, the roller core 16 is in the edge region of the rollers 7 and 8,
It is enlarged to a spacer disk 20 coaxial with the axes 9, 10. When two press rollers 7, 8 each with one spacer disk 20 are brought into their loading position,
The areas of the resilient peripheral wall 18 that abut each other are compressed until the opposing rigid spacer disks 20 abut. Further compression of the peripheral wall 18 and thus further pressure build-up is prevented by the spacer disk 20.

The press rollers 7, 8 shown in FIGS.
According to an embodiment of the invention, these press rollers 7, 8 are used for applying the preparation. For this purpose, a container 21 for the preparation is provided in the inner chamber of the press rollers 7,8. This container, according to FIGS. 6 and 7,
It is configured as a hollow cylindrical hollow chamber formed between the roller core 16 and the peripheral wall 18. In this case, the peripheral wall 18
Has a number of discharge openings 22 distributed over the entire surface. Through these discharge openings 22, during the pressing operation, the preparation is discharged from the container 21 to the outer peripheral surfaces 13, 14, from where it is distributed to the hair.

In this case, the container 21 can be used as a storage container for the preparation. However, it is also conceivable to use the container 21 simply as a dispensing chamber for the preparation. In this case, the preparation is introduced into the container 21 during the pressing operation from a storage container (not shown) arranged outside the press rollers 7, 8. The discharge of the preparation through the discharge opening 22 is based on gravity, at least in the case of a fluid preparation. Alternatively, the dispensing of the preparation can be assisted, for example, by compressed air.

The press rollers 7, 8 shown in FIGS.
Is provided with a trough-shaped storage casing 23 for the preparation in the form of droplets. The preparations collected in the storage container 23 are caught by the outer peripheral surfaces 13 and 14 of the rotating press rollers 7 and 8 and supplied to the hair.
