Open the CIPO recordAbstract From the Canadian patent
The present invention is an improved flosser device for holding and manipulating floss during flossing. The flosser employs a forked tine design for retaining the floss, whereby the floss is maintained in an orientation essentially perpendicular to the longitudinal axis of the handle of the flosser but offsets the tines both onto, one side of the handle to make it much easier to view the area being flossed. Aslanted base is also provided to allow the flosser to be stored on end with the tines, kept away from contamined surfaces.

Why it's free to use
- Filed November 3, 1995 and granted May 2, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 3, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 3, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
