ABSTRACT:
A flosser has an elongate configuration with a forked arm at one end and an enlarged opposite end for housing a spool of unused dental floss, and a take-up reel for storing the dental floss as it is used. The dental floss is strung from the spool, across the arm, and back to the reel. There is a free knob having a spindle which connects the reel so that the feed knob and reel rotate in unison to reel in the spent floss. There is a cylindrical crown projection at the housing end that mates with the feed knob and encases the spool of unused dental floss. The feed knob and crown projection have a clutch mechanism allowing the feed knob and take-up reel to rotate in only one direction and to frictionally engage and hold the floss at the spool end and to temporarily disengage the floss when the feed knob is rotated to allow a measured amount of fresh floss to unwind from the freely rotatable spool, while simultaneously reeling in a like amount of spent floss into the take-up reel. The clutch mechanism rotates in incremental steps to advance new floss across the forked arm. The clutch mechanism also prevents the take-up reel from unwinding when the feed knob is at its at-rest position. Additional guide posts and guideways on the frame also provide tautness to the strung dental floss to keep it sufficiently taut while the invention is being used to floss teeth.
