  • Patent number: 11534280
    Abstract: A dental floss holder and flosser is provided. The flosser provides a reusable dental device for cleaning between the user's teeth. The flosser comprises a casing, a pair of tines, and a floss advancement reel. A bundle of floss resides within the casing. A length of dental floss from the bundle of floss is fed through the casing and into the floss advancement reel. The length of dental floss is wrapped around the floss advancement reel. The length of dental floss is then strung taut along the pair of tines, forming a fresh segment of dental floss. The remaining length is routed and wrapped back to the floss advancement reel. A user can then rotate the floss advancement reel such that the segment of dental floss is replaced and ready for the next use.

  • Patent number: 11284977
    Abstract: The present disclosure refers to an apparatus for flossing teeth having a handle with a fixed anchor point for holding one end of a length of dental floss that passes through an eyelet and is affixed to a breakaway anchor tab on a lever. Breaking the breakaway anchor tab releases one end of the floss so that it may be pulled through a space between teeth. An adjustment lever allows for the easy transition of the flossing loop from tight for the insertion process to slack to enable the flossing process. The guidelines for flossing require that the flossing loop should form the required “C” shape around the base of the tooth.

  • Patent number: 8127779
    Abstract: The utility model of a dental floss holder concerns a device to handle dental floss to clean the spaces between the teeth consisting of two interconnected but easily separable holder portions: Portion 1—U shape supporter is provided with a U supporter (1) with two folding legs, connecting part (2) with longitudinal groove (6) and external thread (7), a hole (3) in the rear leg, a groove (4) that goes externally from the end of the front leg to the fixed end of U supporter (1) to hold the dental floss in position during cleaning operation. Portion 2—Hollow grip provided with a fixed side with a longitudinal inner blade (8) and the rotating side with a rotary end (9) and an internal thread (10). These two portions constitute a mechanism that limits the maximum floss tension adjusted by the rotary end (9). The device can operate with a piece of floss or from a floss supplier (12) connected to the rotary end (9).

  • Publication number: 20120042897
    Abstract: A flossing tool and dispenser. The flossing tool and dispenser can include a body having a handle end and an operative end, a cavity defined within the body and disposed substantially at the handle end, a first tong and a second tong disposed at the operative end, and defining a gap for tensioning a strand of dental floss therebetween, a recess disposed between the handle end and the operative end, an aperture extending between the cavity and the recess, and a cam disposed within the recess, and movable between a first position and a second position, wherein the cam is positioned such that, when the cam is in the first position, the cam impedes the movement of the strand of floss by causing the strand of floss to be pinched simultaneously at two locations along the length of the strand of floss, and, when the cam is in the second position, the cam does not impede the movement of the strand of floss.

  • Publication number: 20110284023
    Abstract: An orthodontic flosser comprising an elongated handle and a head coupled to the handle at a vertical angle is disclosed. A first and second projection extend from the head for suspending floss, the first projection is sized for insertion of floss between a wire affixed to a tooth and the tooth. A source spool of fresh floss is configured to feed fresh floss incrementally into suspension between the first and second projections while a take-up bobbin is configured for taking up used floss and applying tension to the suspended floss. A button may be used for releasing the source spool to rotate, and for holding the source spool against rotation. The source spool and take-up bobbin may be disposed in separated chambers to reduce cross contamination.
