Definitions

  • the invention relates to a hair curler for winding human hair, comprising a base body of a formative shaped part having a central region with a winding surface for winding a hair part, wherein the curler has a first thermochromic substance which at a temperature increase when passing through a first temperature range by a occurring color change indicates a first temperature.
  • a curler of the type described above is known from the German patent application DE 198 43 800 A1 known.
  • the curler has a main body, which preferably consists of plastic and is covered with a foam layer.
  • the foam as part of the hair curler can contain a temperature-activatable substance, suitably a thermochromic color concentrate, which shows a color change when the temperature rises when a predetermined temperature is reached.
  • hair curlers are known in numerous forms and design options, for example from the German patent applications DE 102 41 772 A1 . DE 199 18 742 A1 or DE 37 13 280 A1 , Such curlers are used to wind up human hair to create curls. They usually have a base body from a formative molding made of hard or soft plastic or metal. Basic body made of hard plastic or metal are usually very stable in shape and thus little yielding and deformable. Basic body of soft plastic, in particular of plastic foam, can be resiliently compressed, bent or otherwise deformed and converted into a corresponding shape. Basic metal body can also consist of metal mesh. Likewise, injection-molded plastic body can be provided with a plurality of openings.
  • All of these basic bodies usually have a central region which has a winding surface for winding up a hair section.
  • the hair section is brought in the known manner either by applying the hair tips or the head end of the hairline on the winding surface and added by appropriate twisting or winding on the winding surface.
  • the invention has for its object to provide a hair curler, which gives the user of the curler on the head of a decision aid, when a hair dryer and when a cooling process should be terminated or can.
  • a problem with using known hair curlers is to maintain appropriate temperatures and / or times during which the hair curler is attached to the head after winding a hair piece.
  • a foehn process takes place, which is to be carried out over a certain time and with an increase in temperature of the wound-up hair part and the curler so that the stability of the curl is favored or ensured as possible.
  • a foehn process is usually followed by a chilling process, ie a period of time in which the hair curler remains intact with the wound hair on the head until the desired temperature reduction has taken place. Only then does it make sense to start the unwinding process to create beautiful and permanently shaped curls receive.
  • the unwrapping process is initiated too early, there is the risk that the curl shape will be at least partially destroyed or impaired.
  • the invention is based on the idea, at least a portion of the body or other component of the hair curler with a first thermochromic substance indicating a temperature increase by passing a temperature range by a color change occurring a first temperature or a first temperature range, and a second thermochromic substance that indicates a second temperature or a second temperature range at a temperature decrease when passing through a lower second temperature range by an occurring color change.
  • the new curler is particularly well suited for home use. However, it can also be used by professionals in hairdressing salons, etc.
  • thermochromic substances can be incorporated into the material of the base body, so that the entire base body has the thermochromic substance as an ingredient. But it is also possible to apply the thermochromic substances only on a part of the body. It is even possible to use the thermochromic substance on another component of the hair curler than the main body, for example on an adhesive strip which surrounds the main body, or on a transverse pin which serves to fasten the main body to the head.
  • the thermochromic substances can also be applied by coating at least on a part of the main body or the curler. This is especially true when a relatively hard plastic or even a metal is used as the material for the main body or another part of the curler.
  • thermochromic substances should be used on a part of the main body or the curler, which remains well visible even after winding a hair part.
  • the end regions of the basic body are suitable in which the hair curler is grasped and handled when the hair section is wound up. It is also sufficient if only one of these end regions is provided on the outside with the thermochromic substances or the thermochromic plastics. It is also possible to arrange only the first thermochromic substance in the first end region and only the second thermochromic substance in the second end region. In this way, the first end region indicates the desired temperature during blow-drying and the second end region indicates the desired temperature during cooling.
  • the end regions may be for the user, e.g. B. by a label to be marked accordingly.
  • thermochromic substances depend on the temperature or temperature range at which the color changes occurring are desired.
  • the thermochromic substances do not show the color change in a digital manner at a very specific temperature, but rather within a certain temperature range.
  • the first occurring color change is thus used in temperature increase, to indicate by reaching the temperature that a termination of the Föhnvorgangs is useful to avoid too high temperatures and thus occurring impairments of the hair.
  • the second thermochromic substance with the second occurring color change is reversed used in lowering the temperature, as it makes sense in particular for a sufficiently low temperature and the course of an associated cooling time. Cooling times in the range of 12 to 20 minutes are sought, at the end of which room temperature or a temperature slightly above room temperature in the range from 20 to 30 ° C., in particular from about 24 to 27 ° C., can be reached.
  • thermochromic plastics are adjusted, selected and possibly used in a mixture of two thermochromic plastics at the same time that both the blow-drying and the cooling-occurring color change on one and the same curler can be seen.
  • the main body can have at least about 2 to 6%, in particular about 4%, of the two thermochromic plastics.
  • the thermochromic plastics may, for. B. be mixed with the base material of the body.
  • Suitable materials for the production of the body are plastics such as polypropylene, polyethylene, polystyrene, acrylic, polyvinyl chloride, polyamide, polyethylene terephthalate, polyester o. The like. In question. These materials apply both to injection molded basic bodies as well as those basic body, which consist of appropriate plastic foam. As plastic foams in particular polyethylene foam, ethylene vinyl acetate foam, polyurethane foam, polyether-amide block copolymers foam, polyester-amide block copolymers foam and polyether foam come into question. In particular, a material for the production of the main body shows good results, which z. B. consists of 92% polypropylene and 8% thermochromic additives. The thermochromic additives may in particular consist of 82% polypropylene and 18% microencapsulated thermochromic substance. The thermochromic substances may also be, for example, polyethylene, polypropylene, polystyrene, etc.
  • the invention is generally directed to the use of a plurality of thermochromic substances on at least a portion of a hair curler for indicating a temperature at a temperature elevation and a temperature at a temperature decrease.
