Description

[Detailed description of the invention]

0001

FIELD OF INDUSTRIAL APPLICATION The present invention involves pre-wetting the hair and wrapping it in a strip over the curlers, applying a liquid or harmonic perm preparation, i.e. a cream or gel preparation, to the curlers, and then applying it to the curlers. Heat energy is applied to the hair curler for a predetermined period of time for treatment, after which the permanent reshaping preparation is washed away and the curler is removed after additional treatment with a liquid neutralizing agent and rinse solution. The present invention relates to a hair shaping device configured as described above.

0002

BACKGROUND OF THE INVENTION During the permanent reshaping of hair by this procedure, the active composition of the permanent wave preparation (e.g. thioglycolate) is reduced by a reductive treatment coupled with applied heat. HS of hair keratin
Split into groups. After neutralization, which recombines the HS groups into disulfide bonds, preferably with a liquid oxidant based on hydrogen peroxide, the permawave conditioning agent is washed away. In principle, the hot air or the heat of the radiator promotes and increases the action of the permwave preparation, but this can also cause some discomfort to the person applying the perm. It is clear that the temperature of the applied hot air or radiator heat must be chosen not to be too high, in order to avoid injury or unnecessary discomfort to persons. Whatever the proportion, the hair structure is more or less damaged by the permanent waving process.

0003

SUMMARY OF THE INVENTION The present invention aims at modifying the known perm-waving process, allowing the person applying the perm to use a less unpleasant method, while at the same time causing damage to the hair structure. The present invention provides a hair shaping device that can reduce the degree of hair loss.

[0004] Based on the procedure first described in the present invention, this problem can be solved by applying thermal energy in a predetermined temperature range to the curlers for a short period of time after wrapping the hair strip onto the curlers and applying the perm preparation. The solution is that the thermal energy stored in the curler is transferred onto the hair curls to which the permanent preparation has already been applied. In other words, the heat is applied over a longer process time, rather than by spraying or radiation.
It is applied by the curler, ie through the internal part of the curler, and practically allows higher temperatures to be applied to the curler, without the risk of burning the hair of the person applying the perm. Due to the higher operating temperature, it is possible to substantially reduce the processing time and it is also possible to use permanent formulations with a low proportion of reducing compositions (for example thioglycolates), thus making it possible to reduce the processing time according to the invention. Waving can be done in less time and causes less damage to the hair structure.

Although it is advantageous to heat the curler between 55°C and 95°C, preferably between 75°C and 85°C, this range also varies depending on different hair tissues or hair damage and (or) may be higher or lower depending on the application of the permanent preparation with various active agents or concentrations.

[0006] In order to carry out the said procedure, a number of hair curlers having electrical resistance heating elements suitable for connection to a power supply are connected and disconnected from the power supply, with electrical connectors led to the outside of the curler. Manually operable contact elements are planned. In this way, the heating of the curlers is started after winding the hair and using the perming preparation, and this is done by connecting said contact elements for a short time to each curler, thereby causing these curlers to are heated to a predetermined temperature, after which the heat is released again after a time delay depending on their heat storage capacity.

Resistance heating elements contemplated for the curler are preferably low temperature heating elements, ie they have a positive temperature coefficient. This means that they have a lower electrical resistance at normal room temperature, and once connected to a power source, they draw electrical energy rapidly;
This means that they are heated very rapidly, so to speak, simultaneously.

With respect to the curler of the present invention, the resistive heater element is preferably one with heat-resistant properties, such that the electrical resistance increases significantly at temperatures significantly above 75° C. and 85° C. , the planned temperature range is held for a very short time.

To ensure that a predetermined temperature is not exceeded, the invention has been extended to a time control device by means of a pair of curler connection devices, which is activated when a pair of curlers is connected to a power source. The power supply is then cut off after a predetermined short period of time which ensures that the curler has just heated up to the given temperature. For example, the power supply can be controlled by program-controlled timing with varying connection times, and in this way it is also possible to heat the curlers to various high temperatures.

Additionally or additionally, each curler is provided with an overtemperature control switch that interrupts the power supply from the contact element connected to the curler when a predetermined temperature of the resistive heater element is reached. You can leave it there.

[0011] In order to ensure that the connection of the contact element to one or the other curler is not missed during the perming process, a cover is placed over (at least partially) the surface of the curler and the set temperature is It is recommended to ensure that a color change occurs when . Lacquers or foils that change color under the influence of temperature are also available. Curlers that have not yet been overheated,
Therefore, it can be recognized at a glance.

A curler connection may be provided at the tip of the curler, in which case the curler connection and the corresponding contact on the contact element may be suitably shaped as a bipolar contact.

Alternatively, the curler connection may also be led to both ends of each curler, in which case the contact elements are in the form of a pair of contact clamps, with each of the two arms positioned on each end. The curlers can then be placed and contact can be released for each curler connection.

The invention will be explained in more detail below with reference to the drawings.

EXAMPLE The curler 10 shown in FIG.
Alternatively, it has a spindle-shaped external shape;
Just like the commonly known curlers, they can be made in various lengths and diameters. Inside the curler 10, a low-temperature conductor with a positive temperature coefficient, ie an electrical resistance heater element 12, is held as a heater element, which is made of a mixture having sufficient heat resistance and insulation properties for heat conduction. 16 is clamped in a cylindrical or spindle-shaped external part defining the shape of the curler, for example a light alloy cartridge 13. This insulating mixture 16 transfers the heat generated in the resistive heater element 12 to the cover element 14 and has some heat storage properties. The outer surface of the metal cartridge 13 is further functionally protected against the aggressiveness of the permanent preparation by a plastic cover 14.

A resistive heater element 12, as shown here.
Both electrical connectors have connector contacts 18a, 1 protruding from the tip cap 11 at both ends of the curler 10.
8b, for which adjusted connector contacts 20a, 20b, as schematically illustrated on the contact elements 22, as in FIG. 2, are fixed as a pair of connecting clamps. Preferably, the clamp is further connected to a power source by a wire 24. Here, the handle 26 of the contact element 22 may hold a power supply element, in which the voltage is reduced to a non-hazardous value for safety reasons.

The power supply element may also be a time control device, which is activated whenever the contact element 22 connected to the curler 10 is switched on by means of a pushbutton 28. . On the one hand, the arm 23 of the clamp is thereby guided to the connector contacts 18a, 18b, and on the other hand, the timing of the power supply is defined by an adjustable and controllable liquid crystal indicator 25 and a push button 28. curler 10 on the outer surface of cover 14 by a single operation of
to a suitable temperature between 75°C and 85°C. By using a cold conductor as the resistive heater element 12, this temperature can be reached in 1 to 2 seconds, so we can also refer to "flash heating" of the curler. In order to prevent the curler from overheating due to the possibility of multiple actuations of the pushbutton 28, each curler is additionally equipped with an overheating switch (or alternatively instead of a time-controlled switch in the power pack). may be provided, which is formed, for example, as a bimetallic switch located between the connector contact 18a or 18b and the resistive heater element 12.

The entire surface of the cover or also all visible end parts after the hair has been wrapped may be coated with some kind of coating, for example a heat-sensitive lacquer or a foil, which is heated to a predetermined temperature. It shows a clear color change in the curler, allowing you to see at a glance whether a particular curler has already been activated by heating or not. On the curler 10 shown in FIG. 1, this coating is simply a time-delayed dot of a suitable heat-sensitive lacquer shown on the left-hand tip cap 11, which is also shown as a round mark. can also be considered.

In the context of the present invention, it will be obvious that modifications and improvements in the process steps or arrangements for carrying out the invention are possible, including, for example, the method of arranging the connector contacts on the curler; It concerns the shape of the contact point and the contact element attached thereto. 3 to 6 show the connector contacts 18 of the curler 10.
Possible modifications regarding the shape and arrangement of a, 18b are shown. Therein, FIG. 3 shows a tip cap 11 with a connector contact 18a, which instead of the spherical part shown in FIG.
9 and is adapted to suitably mate with a corresponding protrusion on the connector contact 20a of the contact element 22.

FIG. 4 shows the arrangement of the connector contacts 18a in the tip cap 11, which are made flush with the flat portion of the tip cap 11 and also have a recess 19. and is adapted to suitably mate with the protruding portion of the connector contact 20a of the contact element 22.

[0021] All the construction examples described so far have contact elements in the form of a pair of connecting clamps, two movable opposing arrangements for holding the curler 10 at its ends. It is equipped with a tong arm 23. Figures 5 and 6 show a tip cap 11 with two connector contacts 18a, 18b, a concentric metallized contact surface 18a and a concentric outer circular connector surface 18b. It is shown. Such a tip cap 11
In order to heat the curler 10 with the curler, the contact tip cap 11 of the curler is placed on one side. It would be necessary to develop a contact element (not shown) that is suitably modified and held in place by a suitably developed notch in the contact element of the tip cap.

It becomes clear that in the context of the invention modifications and improvements to the example described above are possible. Instead of the described curlers for curling the hair, one modification is to use hair clamps to hold the curled or wavy hair between the levers. However, it is important that these hair clamps also be able to be properly heated to the desired temperature by a short-term supply of energy.
