Abstract: A self-dispensing dental floss applicator that has a U-shaped elongated housing (1) with two hollow prongs (4a, 4b) set perpendicularly to the body at one end and a larger opposite end to contain the locking mechanism, the dispensing mechanism, the spool (3) of fresh floss and the spool (18 or 21) of used floss. The locking mechanism composed of a casing (5), an axle (9), two lower grip pads (17a, 17b), two upper grip pads (7a, 7b), two strip springs (8a and 8b) 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. A tension pin (19) containing a screw (20) is provided to increase floss tension if/when needed by the user. Rotating the lever (6) up unlocks the floss. Further repeated rotations of the lever backward action the sliding mechanism containing a rack-and-pinion gear (23 and 21), together with springs 24 and 26, that in turn causes the spool of used floss (21) to rotate.

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.
