Abstract

The applicator is tong-shaped with two crossed arms (2,3) and pressure roller (7,8) on the end (5,6) of each arm. Rollers turn about parallel axis (9,10). When the grips (11,12) of the lever arms are pressed together, the jacket surfaces (13,14) of the rollers are pressed against each other, applying pressure to the hair, treated with a care product. One roller has an elastic material cover, the other has a profiled surface. The applicator may have an electric drive motor (M), and/or a roller heater.

Description

The invention relates to a device for introducing a into a preparation active ingredient contained in hair.

Präparat" wird daher jedes Mittel verstanden, das zur Erzielung einer bestimmten Wirkung auf das Haar aufgetragen wird. Darunter fallen Reinigungsmittel (oder Shampoos), Haarkuren, Wachse, Öle, Mittel zur Strukturumformung von Haar, wie z.B. Haarglättungsmittel oder Dauerwellen und zur Verbesserung der Kämmbarkeit verwendete sogenannte Oberflächen-Glätter". Des weiteren umfaßt der Begriff Präparat" auch Mittel zum Färben oder Ausbleichen von Haar sowie sogenannte Finish-Produkte", d.h. Mittel zum Imprägnieren von Haar, Festigen einer Frisur oder Mittel, die den Eindruck nassen Haars erwecken (sogenanntes Wet-Gel").It is common practice to treat hair with active ingredients contained in preparations for cleaning or care purposes or for cosmetic reasons. Under the label

Preparation "is therefore understood to mean any agent that is applied to the hair to achieve a certain effect. This includes cleaning agents (or shampoos), hair treatments, waxes, oils, agents for structuring hair, such as hair straighteners or permanent waves and to improve combability used so-called Surface smoothers ". The term also includes Preparation "also means for dyeing or bleaching hair and so-called Finish products ", ie means for impregnating hair, setting a hairstyle or means that give the impression of wet hair (so-called Wet gel ").

Such a preparation is usually done by hand, with a brush or Sponge or sprayed on the hair. A high proportion of the active ingredient contained in the preparation is only deposited on the hair surface, while only a comparatively small proportion of the active ingredient inside of the hair penetrates. Because of the influence of water, sun or other Environmental factors of the superficially deposited active ingredient are easily removed or decomposes, the effect of the preparation wears off quickly. To still be one To achieve a sufficiently long-lasting effect of the hair treatment, the Active ingredient can be used in a high dosage. Such an overdose the active ingredient is costly on the one hand. On the other hand, a high dosage of active ingredient may damage the hair.

When applying colorants, it is also disadvantageous that due to the superficial color application the colored hair has a different light refraction as natural hair of a comparable color. Dyed hair does often gives the viewer a dull or lackluster impression and is reflected on it Initially identified as artificial.

The invention is therefore based on the object of introducing a device specify an active ingredient in hair that increases the effectiveness of the Allows preparation containing active ingredient.

With regard to the method, the object is achieved according to the invention by Features of claim 1. There are two about substantially parallel axes rotatable pressure rollers provided for generating a mechanical pressure can be pressed against each other with an area of their lateral surfaces. That too treating hair is used (comparable to one used for pressing steel Slab) passed between the pressure rollers. The pressure rollers are operated at the ends of the action two crossed like a pair of pliers Lever arms attached.

The active ingredient is thus applied to the hair by applying external pressure brought in. The pressure to be applied clearly exceeds the natural pressure Acting on the hair, such as that caused by air pressure or is caused by a head massage. The pressure also exceeds that Clamping force of a z. B. from DE 36 22 232 A1 known static hair clips to apply treatment liquids to the hair.

In principle, it is possible on the one hand to apply the preparation and the To carry out pressure treatment as two temporally separate process steps. On the other hand, the preparation can already be applied to the hair under pressure become. Driven by the pressure application always comes in increased active ingredient in the inside of the hair. This increases the porous suction Hair tissue when the pressure decreases like a sponge that Hair surrounding preparation. Instead of just a superficial application, as is the case when using the well-known hair clip, that is Hair soaked with the preparation after the pressure treatment to an increased extent.

The active ingredient that has penetrated into the inside of the hair is not only high here Measures against rinsing and decomposition - for example due to solar radiation - protected. The active ingredient is also present in the entire volume of the hair tissue distributed and can therefore fully develop its effect. When using Coloring agents get the color pigments as an active ingredient as a result of the pressure treatment in the hair cortex under the surface of the hair. In this The natural color pigments of the hair also lie in the layer. With the help the colored hair retains its natural light refraction.

By combing the near-surface hair tissue, especially with the use of a surface straightener, good combability is achieved. The disadvantageous weighting of the hair is largely avoided. Likewise, when using a Finish product "virtually seals the hair against damaging environmental influences. The improvement achieved is comparable to the improvement which is achieved by high-pressure impregnation of wood compared to a normal wood preservative coating.

The device designed as a pressure tongs advantageously contains one particularly simple mechanics for exerting the mechanical pressure on the hair that can be guided between the pressure rollers. A manufacture of this pliers is therefore possible at low cost. For handling the device and thus to carry out the procedure are not professional Previous knowledge required. Due to the reinforcing effect of the lever arms simply apply enough pressure by hand to treat the hair become. As a result of the rotatable rollers, the hair is only turned laterally, i.e. across its direction of extension. A painful move for the customer the hair in its longitudinal direction is largely avoided. Of the train remaining due to the rolling resistance of the pressure rollers can do so be exploited, a smoothing agent using the device in wavy hair to bring in, and simultaneously pull this straight.

The pressure rollers are preferably angled in this way on the ends of the lever arms placed that the axes of the pressure rollers approximately perpendicular to the crossing plane the lever arms stand. This will handle the device simplified. In addition, the axes of the printing rollers take in this arrangement regardless of the position of the lever arms always the same angle on. In particular, this means that the pressure exerted by hand is always uniform is distributed over the entire length of the roller.

By at least one, but expediently each pressure roller with a jacket an elastic material, especially a rubber or foam-like Material that is provided is a particularly good embedding of the hair in the Roll material achieved. The hair is not squeezed. Rather it becomes a Exerted largely homogeneous pressure over the circumference of a hair. The properties of the jacket material with regard to its hardness, absorbency etc. appropriately selected depending on the application.

Especially when using the device together with viscous colorants it makes sense to cover the lateral surface of at least one pressure roller with a relief-like one To provide surface structure. With smooth outer surfaces of the printing rollers a high proportion of the preparation would be comparable to a bow wave pushed in front of the printing rollers. A relief-like surface structure, for example in the form of knobs, recesses or grooves, increases the adhesion of the preparation on the surface of the printing rollers.

When using circumferentially, annularly closed depressions as the surface structure, it is made possible in a simple manner according to a further development of the invention, so-called To color comb strands ".

This means thin colored strands of hair that alternate one type Stripe pattern lying next to undyed strands.

A pair of rollers provided with a relief-like surface structure can continue be improved if the surface structures of the corresponding Rollers are designed complementary; i.e. if every lead on the Surface of the one roller in a form-fitting manner in a corresponding recess engages on the surface of the other roller. This way the pressure distributed particularly homogeneously over the entire length of the roller.

For a special purpose (i.e. the use of a specific one Preparation) a pair of pressure rollers is used, which with regard to whose properties are particularly well adapted to the intended use. Printing rollers for different purposes differ accordingly in properties such as surface hardness and radius. You can also the surface structure, absorbency and length of the pressure roller vary become. It may also make sense to have your own for different colors To use a pair of pressure rollers. So as not to swap the printing rollers To have to replace the entire device is preferably provided Pressure rollers releasably connected to the effective ends of the lever arms. Here an easy and quick to disconnect connection is preferable. Suitable are, for example, snap or bayonet connections.

On the one hand the pressure treatment with regard to a special application to optimize, and on the other hand with a variety of different Preparations each give the best possible result of the pressure treatment To achieve, in an advantageous embodiment, means for setting a predefined and adapted to this application pressure. Here the pressure to be used is preferably dependent on the preparation regulated. Additionally or alternatively, a variation of the pressure is dependent useful from the properties of the hair to be treated.

The maximum pressure to be applied can be particularly easily limited by in the edge area of each pressure roller to this coaxial spacers from a hard material. Likewise, the attachment of stops or ratchet-like snap connections as pressure limiters on the lever arms possible. Such pressure limiters are e.g. of pliers-shaped end insulators for Power cable known. Of course it is still possible to use mechanical or to provide electrical pressure gauges.

It is advantageous to provide at least one pressure roller with a drive. A painful tension of the hair at the hairline for the customer Pulling the hair through the pair of rollers can be avoided in this way. This drive can mechanically, e.g. done via a crank. Especially for the professional However, use of the device becomes a crucial simplification the handling achieved by an electric drive. Especially at It is of course advisable to take precautions, such as in the form of an electric drive Torque clutch to hit in the event that accidentally too strong Tension is exerted on the hair.

For many preparations, it is advisable to apply additional pressure treatment Support supply of heat. This can, on the one hand, cause swelling of the Hair are encouraged. This in turn facilitates the penetration of the active ingredient inside the hair. On the other hand, e.g. in sheet metal, a chemical Reaction of the active ingredient in the hair can be accelerated by heat. Finally, it may also make sense to use the hair during the Dry pressure treatment with heat. By integrating a heating unit In at least one of the printing rollers there is therefore a combined printing and Heat treatment particularly easy to carry out.

To further simplify the introduction of the active ingredient contained in the preparation in the hair can also according to professional use tailored application of the preparation and the pressure treatment can be combined in one step. This is done in at least one pressure roller a container for the preparation is provided, which with the over the lateral surface of the Pressure roller distributed outlet openings is connected.

Numerous other embodiments are conceivable. So it is advantageous, at least to surround a pressure roller with a trough-shaped collecting housing. With such a collection housing, as is the case with painting rolls is known, an annoying dripping of the preparation from the pressure roller be prevented. This collecting housing can be designed in such a way that the collected preparation is automatically taken along by the pressure roller and is transported back to the hair.

Furthermore, it is also conceivable to connect several pairs of printing rollers in series. This may be useful if different pairs of pressure rollers for different Tasks are specialized. For example, with a first pair of pressure rollers Means for applying the preparation may be provided while a second pair of pressure rollers contains a heating unit. Likewise, the pair of pressure rollers can Comb can be connected upstream. In such an arrangement, the hair is well organized and pulled evenly through the pair of pressure rollers. An irregular one Pressure distribution due to thick knots in the treated strand of hair does not occur. Comb with hair straighteners results in a additional smoothing effect during pressure treatment.

Fig. 1 shows the device designed as pliers 1 for introducing a Active ingredient in hair. This comprises two crossed lever arms 2 and 3. The lever arms 2 and 3 are like a pair of pliers at their crossing point around a common one Lever axis 4 pivotally mounted against each other. At the end of action 5 and 6 of the lever arms 2, 3, a pressure roller 7 and 8 are rotatable appropriate. The axes 9 and 10 of the pressure rollers 7 and 8 are mutually arranged in parallel. In addition, axes 9 and 10 are parallel to the lever axis 4. In other words: the axes 9, 10 are perpendicular to the crossing plane lever arms 2 and 3.

To carry out the method with the aid of FIG. 1 on the The most necessary reduced pressure tongs 1 are first the preparation in a conventional manner Way applied to the hair. For this purpose e.g. used a brush become. After that, a strand of hair is divided and generally close to the Hairline introduced into the gap S formed between the pressure rollers 7 and 8. By manually compressing the actuating ends 11 and 12 of the Lever arms 2, 3 are the pressure rollers in their (not shown) loading position spent. The pressure rollers 7 and 8, which the strand of hair between lead like a slab a piece of steel to be rolled, are now over the unrolled entire hair length. As already mentioned, the handling of the Device and comfort for the customer by means of an electrical or mechanical Drive, preferably in the form of a schematically illustrated motor (M), at least one pressure roller 7,8 significantly simplified or improved become. Such a motor (M) can expediently in the pressure roller 7,8 or in a lever arm 2,3. Furthermore, at least a pressure roller (7,8) a (not shown) heating unit - approximately in shape an electric heating coil - included.

Fig. 2 shows an embodiment of the device, especially for viscous Preparations such as Colorant, is particularly suitable. Here are the lateral surfaces 13 and 14 of the pressure rollers 7, 8 with knobs 15 to produce a relief-like Provide surface structure. Due to the relief-like, i.e. rough surface structure the viscous preparation becomes stronger on the surface of the pressure roller 7.8 bound. A displacement of the viscous preparation by the Pressure rollers 7.8 comparable to a bow wave therefore only take place in a reduced amount Scale instead. A comparable effect can of course also be achieved with others achieve three-dimensional surface patterns, such as grooves. The pressure rollers 7, as shown in FIG. 2, have an approximately star shape Cross section on. For the rotatable mounting of the pressure roller 7,8 includes this a hollow cylindrical roller core 16, which is rotatably connected to the lever arm 2,3 connected axis rod 17 concentrically surrounds. The roller core 16 is again surrounded by a jacket 18. This jacket 18 preferably consists made of an elastic material.

By moving the pressure roller 8 to the pressure roller 7 in the travel path L the pressure roller 8 in its loading position shown in outline in Fig. 3 spent with respect to the pressure roller 7. The pressure roller 8, the axis 10 and the lateral surface 14 are in the position of application with the reference numerals 8 'or 10' or 14 '. As can be seen from Fig. 3, the The outer surface 14 'of the roller 8' with the outer surface 13 of the pressure roller 7 in a form-fitting manner To get involved.

Fig. 4 shows a further development of a printing roller with a relief-like surface structure, especially for the production of so-called For this purpose, the pressure roller has a series of annularly closed recesses 19 which run in the circumferential direction around the circumferential surface 13 of the pressure roller 7. In a longitudinal section through the pressure roller 7 according to FIG. 4, the result is an image of tines on both sides To produce the comb strands, some of the depressions 19 are filled with a coloring agent, after which a strand of hair is inserted between the roller 7 and a pressure roller 8 (not shown) with a complementary surface structure, as was previously the case, when the rollers 7 and 8 and Rolling the rollers 7, 8 over the strand of hair, the hairs lying in the color-filled recesses 19 are dyed as comb strands in a kind of stripe pattern.

In an advantageous embodiment of a pressure roller 7, 8 according to FIG. 5 when the pressure rollers 7,8 are pressed together, a predefined maximum pressure is set become. The roller core 16 is closed in the edge region of the coil 7, 8 a spacer 20 coaxial with the axis 9, 10 widened. Become two each with a spacer 20 provided pressure rollers 7 and 8 in their loading position spent, so the contiguous areas of the elastic jacket 18 compressed until the opposite hard spacers 20 come into contact. Another compression of the Jacket 18 and thus a further increase in pressure is through the spacers 20 prevented.

According to an embodiment of a pressure roller 7, 8 shown in FIGS. 6 and 7 can also be used to apply a preparation. This is in Interior of the pressure roller 7, 8 a container 21 is provided for the preparation. This 6 and 7 is formed as a hollow cylindrical cavity which between the roller core 16 and the jacket 18 is formed. The jacket 18 contains a number of outlet openings distributed over its entire surface 22. Through this, the preparation emerges from the pressure treatment Container 21 on the outer surface 13, 14 and is distributed from there to the hair.

The container 21 can be used as a storage container for the preparation. However, it is equally conceivable to use the container 21 only as a distribution space to use for the preparation. In this case, the preparation is made from an outside the pressure roller 7,8 arranged (not shown) reservoir introduced into the container 21 during the pressure treatment. The exit of the Preparation through the outlet openings 22 can at least in the case of low-viscosity preparations due to gravity. Alternatively, the preparation can exit for example, be supported by compressed air.

The pressure roller 7, 8 shown in FIGS. 6 and 7 has a trough-shaped collecting housing 23 provided for dripping preparation. The drug that is in the collecting housing 23 accumulates, the outer surface 13, 14 becomes rotating pressure roller 7.8 detected and conveyed to the hair.
