Abstract: The stem extended from the handle has a slot in the center dividing it into two halves. The ends of two halves branch out to form a ‘Y’ structure and then each extended forwards to form two prongs. Each prong is bent downwards 90 degrees at two thirds of its length with a ‘T’ shaped slit in the tip. The ends of the arms of the ‘Y’ structure are connected by a link. A sliding button holds the new floss and the return floss. With the button in the slot and the floss routed through the guiding rings in the arms of the ‘Y’ structure, under the link, up and over the prongs and through the ‘T’ slits, pulling the button towards the handle creates the tension in the floss, rotating the button feeds new floss across the tips and rewinds the used floss onto the button.
