Abstract
A flossing device includes a housing that can be gripped as a handle. The housing has a hollow interior with first pawl teeth. A spool is placed inside the hollow interior and includes second and third pawl teeth disposed on opposite ends. The second pawl teeth, when engaged with the first pawl teeth with assistance from a spring, allow the spool to rotate in a first direction relative to the housing. The flossing device also includes a tail cap that has fourth teeth that engage the third pawl teeth to urge the spool in the first direction. The flossing device also includes a fork for suspending a length of floss received from the spool and used for flossing. The length of floss is tightened by rotation of the spool in the first direction. The length of floss can be replaced by rotation of the spool in a second direction opposite the first direction.
