Abstract
Abstract A steam curling iron having a tubular body with apertures therein, a heating element disposed in a heating chamber in the tubular body, and a fluid dispensing device mounted at one end of the tubular body including a reservoir for storing a fluid and a metering mechanism for supplying a metered quantity of the fluid from the reservoir to the heating chamber such that the heating element evaporates a predetermined amount of fluid for application through the apertures to hair wound around the tubular body. The tubular body has axial depressions in the outer surface thereof with the apertures positioned in the axial depressions to emit steam tangentially of the tubular body, and a clip extends along the tubular body for holding the ends of a tress of hair wound around the tubular body, the clip being mounted in a housing at an end of the tubular body opposite the fluid dispensing device to be pivotally biased against the tubular body and to be movable away from the tubular body in a direction transverse to the longitudinal axis of the tubular body to permit hair wound around the tubular body to be axially removed therefrom.
