ABSTRACT:
A self-dispensing dental floss applicator has a U-shaped elongated housing (1) with two hollow prongs (4a, 4b) at one end and a larger opposite end to contain the locking mechanism and the spool (3) of fresh floss. The locking mechanism composed of a casing (5), two grip pads (7), a spring 8 and a lever (6) with two eccentric friction parts is used to hold the floss in position thus creating the right tension on the floss. After rotating the lever (6) up, a length of floss from the spool (3) is initially pulled through one side of the locking mechanism, spanned through the two prongs (4a, 4b) and then pulled through the other side of the locking mechanism. The used end (16b) of the floss passes through an aperture in the cover (2) and a surplus length thereof is cut off by a cutter. By pulling the floss by hand at the bottom part of the instrument, fresh floss (16A) is spanned between the prongs for use.
