  • Patent number: 4308878
    Abstract: A curling iron holder formed of molded plastic and defining a central cavity sized to receive the heated portion of a conventional curling iron. The diameter of the cavity is greater than that of the heated portion of the curling iron so that there is an annular space between the outer surface of the curling iron and the inner surface of the cavity. Extending into the cavity at longitudinally limited sites is a plurality of centering guides which hold the curling iron centrally of the cavity to maintain such annular space. There are openings at opposite ends of the annular space to afford air circulation therethrough. At one end of the cavity is an enlarged mouth which facilitates entry of the curling iron and which assures that the heated parts thereof are entirely surrounded by the holder. An external linear rib adjacent the mouth prevents the holder from rolling on a flat surface. On the external surface of the holder is a pair of cord cleats which afford compact storage of the curling iron cord.
