ABSTRACT:
A manually powered hygienic dental floss dispenser enclosed in a housing. A user pulls a lever connected to a first drive belt engaging a free wheel and an inner ratchet wheel, causing the wheels to rotate clockwise. When the user releases the lever, a spring pushes the lever back toward its original position, causing the inner ratchet wheel to engage an outer ratchet wheel engaged with a second drive belt and a daisy wheel. Counterclockwise rotations of the wheels cause the daisy wheel to engage and advance a string of dental floss at pairs of opposing radial extensions of the daisy wheel. When the lever reaches its original position it activates a cutting mechanism that severs the string of dental floss at a measured length. The measured length of dental floss passes from the interior to the exterior of the housing through a feed tube.
