Description

The invention relates to a method according to the preamble of claim 1 and an apparatus for performing the method according to the genus of Preamble of claim 2.

• Wärmestrahlgeräte heizen den ganzen Kopf einer Person auf. Dadurch sind nur geringe Temperaturerhöhungen des Behandlungsmittels an der Kopfhaarsträhne möglich, wodurch eine Behandlung zur Farbveränderung der Haarsträhnen sehr lange dauert (ungefähr 20 bis 45 Minuten).
• Lange Behandlungsdauer, auch wenn nur wenige farbveränderte Haarsträhnen erzeugt werden sollen.
• Hoher Energieverbrauch, da das Wärmestrahlgerät den ganzen Kopf erwärmt.
• Unangenehmes Ziehen an den Haarsträhnen bei einer so genannten Kunststofffolienhaubentechnik, bei der mit einer Häkelnadel die Kunststofffolienhaube durchstoßen und eine Haarsträhne herausgezogen wird.
• Das Behandlungsmittel kann an unerwünschten Stellen gelangen.

Such methods and devices for changing the color of hair tresses by means of a treatment agent are known in various versions from obvious prior use. For example, hair strands to be bleached are produced with heat radiation devices for the purpose of shorter treatment times. This method has the following disadvantages:

• Radiant heaters heat up a person's entire head. As a result, only slight increases in the temperature of the treatment agent on the hair strand are possible, which means that a treatment for changing the color of the hair strands takes a very long time (approximately 20 to 45 minutes).
• Long treatment time, even if only a few color-changed strands of hair are to be created.
• High energy consumption because the radiant heater warms the entire head.
• Unpleasant pulling on the strands of hair with a so-called plastic film hood technique, in which a crochet hook pierces the plastic film hood and a strand of hair is pulled out.
• The treatment agent can get to unwanted places.

It is therefore an object of the invention to provide a method and apparatus for Color change (color accentuation) of hair strands using a To create treatment agent that does not have these disadvantages.

This object is achieved according to the features of the characterizing part of claim 1 and claim 2. Further advantageous
Further developments / refinements of the invention emerge from the subclaims

The invention is described in more detail by an embodiment.

First, a device 1 for performing the method for Color change of hair tresses closer with a treatment agent 1 shows a device 1 for changing the color of Hair strands 2 shown by means of a treatment agent 3. The device 1 consists of a separate, flat strand pad 4 and a separate, electric heating unit 5, which is provided with a flat heating plate 6, the Hair strand 2 is enclosed by a protective film 7 and on the Streak pad 4 lies. The hair section 2 stands for a heat treatment for a predetermined time with the heating plate 6 in thermal contact. Preferably, the Hair section 2 of a heat-resistant and transparent (plastic) Protective film 7 enclosed.

Fig. 2 shows a section through the heating unit 5, the heating plate 6 with a Spacer 8 is provided to the flat side of the strand pad 4, whereby it is avoided that the treatment agent 2 through the heating plate 6 from the Protective film 7 can be pressed. A distance of approximately 2 mm has proven useful. For heating the heating plate 6, an electric heating element 30 is provided which by a cable 31 is supplied with electrical energy. The heating unit 5 is with one Provided housing 32 which by means of a heat insulating mass 33 against heating of the heating element 30 is protected. Optionally, the heating unit is 5 with one Timing device 17 provided, with which the duration of the heat transfer to the Hair section 2 can be checked. The time lapse device is optional 17 coupled to a signaling device 18 with which a start button 17.1 when the process expires an optical and / or acoustic signal occurs at a predetermined time.

3 to 6 show the heating unit 5 in different views.

For better handling of the strand base 4, this is as a spatula 9 (Fig. 7) - preferably made of suitable plastic - designed and optionally at one end provided with a mounting comb 10 (Fig. 14 to 23), whereby the spatula 9 on a hairline 34 (Fig. 19 and 20) or the beginning of the hair of the hair section 2 again can be releasably attached. For this purpose, the spatula 9 has a fastening comb 10 first, fixed row of tines 11 with tines 15 (Fig. 7 to 11) with one below arranged, spring-loaded second tine row 12 (Fig. 12 and 13) of a lower Comb part 35 corresponds in such a way that a spring 13 (FIG. 12) with flanks of the Tines 14 of the second row of tines 12 against flanks of the tines 15 of the first Row of tines 11 presses (Fig. 16). By manually pressing an actuation button 36 against the force of the spring 13, both rows of tines 11, 12 are pivoted 37, 38 brought into congruence (FIG. 14), with which a strand of scalp hair 2 Tine spaces 16 of the first row of tines 11 and tine spaces 16 of the second row of tines 14 are continuous. The pivot bearing 37.38 is as one Snap connection formed, with which an easy removal of the lower comb part 35 is possible for cleaning both parts (spatula 9 and comb part 35). The spring 13 corresponds to a counter bearing 39, which is on the lower side of the spatula 9 is arranged. The spring 13 is in one piece with the lower comb part 35 made of plastic designed, optionally using a separate spring made of metal can.

In order to thread the hair of the hair section 2 into the fastening comb 10, the tines 14 of the lower comb part 35 with the actuation button 36 under the tines 15 of the upper first row of tines 11 are pushed. Now the mounting comb 10 opened and the hair can be brought in (Fig. 19). Are the hair in the Fastening comb 10, the actuation button 36 is released. The spring 13 presses the tines 14 of the second row of tines 12 now into the tine spaces 16 of the upper first row of tines 15. The hair is now pretensioned by the spring 13 between the prongs 14 of the lower comb part 35 and the prongs 15 of the upper first row of tines 11 clamped (Fig. 20). The hair is now firm with the spatula 9 connected. The spatula 9 is released from the hair by pressing the Actuation button 36 and the removal of the strand of hair 2.

So that the hair is always on the right side of the prongs 14, 15 the tines 15 of at least the upper first row of tines 11 are L-shaped. With this design, the tines 14 of the second row of tines sink 12 in actuated state in the tines 15 of the first row of tines 11. The design of the Prongs 15 in a U shape are also possible, but more difficult to manufacture.

Another advantage results from the sealing effect of the fastening comb 10. If the attachment comb 10 is attached to a strand of hair 2, the Tine spaces 16 closed. When subsequently applying chemical preparations can not get on the scalp. The poet Effect can be increased if at least one of the touching Tooth flanks are coated with an elastic material. This coating would also increase the friction between the prongs 14, 15 and hair 2 and thus the holding force on the hair strand 2 enlarge.

21 shows an enlarged representation of tines 15 of the first row of tines 12 and tines 14 of the second row of tines 12 in a first and second position. The Fig. 22 and 23 show corresponding two further exemplary embodiments of tines 14, 15.

A top view of the device 1 with the heating unit 5 on the strand base 4 (Spatula 9) in a heat treatment position is shown in FIG 25 shows a corresponding side view. A corresponding section XXVI-XXVI 25 is shown in FIG. 26.

The method for changing the color of hair strands 2 by means of a Treatment agent 3 under the influence of heat is that first a Protective film 7 is placed on a flat tress pad 4 and the Lock of hair 2, on which the treatment agent 3 is then applied, then a free part of the protective film 7 is folded and placed on the hair section 2 and then a heating plate 6 is placed on the hair strand 2 for a predetermined time, the treatment agent 3 then being rinsed out of the hair strand 2 and is neutralized if necessary.

1. Schutzfolie 7 auf den Spatel 9 legen.

2. Kopfhaarsträhne 2 abteilen.

3. Spatel 9 an die Kopfhaarsträhne 2 legen bzw. befestigen und die Kopfhaarsträhne 2 auf die Schutzfolie 7 legen.

4. Behandlungsmittel (Blondier-/Färbmittel) 3 auf die Kopfhaarsträhne 2 auftragen, beispielsweise mittels eines Pinsels.

5. Schutzfolie 7 falten und die Heizplatte 6 an der vorgesehenen Stelle auf den Spatel 9 setzen und die Zeitablaufeinrichtung 11 starten (wobei die Kopfhaarsträhne 2 auf ungefähr 85 Grad erwärmt wird).

6. Je nach gewünschtem Behandlungsgrad (Aufhellungs- bzw. Färbegrad) wird die Heizeinheit 5 nach ungefähr 1 bis 2 Minuten wieder von der Kopfhaarsträhne 2 entfernt.

7. Kopfhaarsträhne 2 auswaschen und neutralisieren, nachdem zuvor die Oberseite der Schutzfolie 7 aufgeklappt oder auch ganz entfernt wird. Das Auswaschen (Spülen) der Kopfhaarsträhne 2 erfolgt vorteilhafterweise auch mit dem Spatel 9, der dann gleichzeitig als eine Abflussrinne dient. Danach wird der Spatel 9 vom Haaransatz 34 getrennt und kann für eine weitere zu behandelnde Kopfhaarsträhne 2 eingesetzt werden.

The process sequence with the device 1 for carrying out the method for changing the color of hair strands 2 by means of a treatment agent 3 under the influence of heat is as follows:

1. Place protective film 7 on spatula 9.

2. Divide hair section 2.

3. Place or fix spatula 9 on the hair section 2 and place the hair section 2 on the protective film 7.

4. Apply treatment agent (bleaching / coloring agent) 3 to the lock of hair 2, for example using a brush.

5. Fold the protective film 7 and place the heating plate 6 on the spatula 9 at the intended location and start the timing device 11 (the hair section 2 being heated to approximately 85 degrees).

6. Depending on the desired degree of treatment (degree of lightening or coloring), the heating unit 5 is removed from the hair section 2 after about 1 to 2 minutes.

7. Wash out and neutralize the hair section 2 after the top of the protective film 7 has been opened or removed entirely. The washing out (rinsing) of the hair section 2 is advantageously also carried out with the spatula 9, which then simultaneously serves as a trough. The spatula 9 is then separated from the hairline 34 and can be used for another section of hair 2 to be treated.

These steps take between 2 and 5 minutes. In the same Working can then directly on the same strand of hair 2 with pulling colors still special color effects can be achieved. Also Oxidation hair colors can be made in the manner described above.
