Abstract Hair curler including a cylindrical wall made of plastic material and a guide tube provided with stop means adjacent each end thereof and mounted within such cylindrical wall so as to form an air space between the cylindrical wall and the guide tube. A central core having substantially the same length as the curler itself and made of a material having a large specific heat is adapted for axial displacement within the guide tube between a first position in which it is completely inserted into the curler and a second position in which one end of the core is projecting from the curler. The core has means cooperating with the above end stops for stopping the core at the above mentioned first and second positions. Pressure means are associated with the core and the guide tube for providing sufficient friction against displacement of the core with respect to the tube.
Hair curler comprising: a. a cylindrical curler wall made of plastic material; b. a guide tube provided with end stops adjacent each end thereof, and mounted within said wall so as to form an air space between said wall and said guide tube; c. a central core having substantially the same length as the curler itself and made of a material having a large specific heat, said core being adapted for axial displacement within said guide tube between a first position in which it is completely inserted into the curler and a second position in which one end of the core is projecting from the curler, said core being provided with means cooperating with said end stops for stopping the core at said first and second positions corresponding to the inserted and projecting positions of the core; and d. pressure means associated witH said core and said guide tube for providing sufficient friction against displacement of said core into said guide tube.
