Benefits of technology

[0011]The first thermochromic plastic is added to improve handling of blow-drying. The second thermochromic plastic is used to improve handing during cooling down. In this way, the ending of both processes is clearly indicated to the user by and color change easily visible with the eye.

Problems solved by technology

A problem during use of known hair curlers is the determination of the period of time during which the hair curler needs to be kept in place at the head after having wound up the hair.
If the unwinding process is started too early, there is the danger of the shape of the curls being destroyed and being negatively influenced, respectively.

Embodiment Construction

[0025]Referring now in greater detail to the drawings, FIG. 1 illustrates a first exemplary embodiment of the novel hair curler 1. The hair curler 1 includes a base body 2 being designed as a form body made of plastic, metal, and the like. Preferably, the base body 2 is designed to be hollow. As seen in an axial direction, the base body 2 includes a center portion 3 and two fixing portions 4 being arranged at its ends. The two fixing portions 4 have the same diameter being greater than the diameter of the center portion 3. In this way, the hair curler 1 has the shape of a coil or a roller with end portions extending in a radial outer direction. Preferably, the entire axial extension of the circumference of the fixing portions 4 is covered by a hook band 5. Such hook bands 5 are known as parts of Velcros. They include a woven or seemed portion including outwardly protruding spikes or hooks 6. Especially, the hooks 6 may be designed as loops which have been opened by cutting. The cent...

Abstract

A hair curler (1) includes a base body (2) including a center portion (3) being designed and arranged to support hair to be wound up. The hair curler (1) includes a first thermochromic substance (20) being designed and arranged to indicate a first temperature during a temperature increase of the hair curler (1) within a first temperature range by a first color change. The hair curler (1) includes a second thermochromic substance (35) being designed and arranged to indicate a lower second temperature during a temperature decrease of the hair curler (1) within a lower second temperature range by a second color change.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to co-pending German Patent Application No. DE 10 2008 007 539.6 entitled “Lockenwickler und seine Verwendung”, filed Feb. 5, 2008.FIELD OF THE INVENTION[0002]The present invention generally relates to a hair curler including a base body including a center portion being designed and arranged for winding up human hair to attain curls.
