US Patent 7234475 Dental flosser

A dental flosser is moveable between a stored, non-use position where the flosser is substantially planar, and an engaged or in-use position where a portion of the flosser is angled relative to the handle to aid in reaching back teeth. The dental flosser preferably includes a holder (which may be a U-shaped holder) that is movable between the non-use and in-use position; a handle; a living hinge between the holder and the handle, and a locking arm designed to secure the holder in the in-use position.
