FLOSS-O-MAT is an improvement on the automated dental floss dispensing apparatus based on and described in the Ippisch model, U.S. Pat. No. 5,645,206 dated Jul. 8, 1997. The changes and improvements to the Ippisch patent as well as the intended use and rational for intended locations and placement of this apparatus are described below. The Ippisch patent claims that it can dispense waxed and un-waxed dental floss and other cordage for dental or medical use. It does not however, claim that the same can dispense "sterile" dental floss or other medical and dental cordage. References to sterility are however implied in the information included in the "BACKGROUND OF THE INVENTION" column 1 lines 20 thru 56. The assumption of any such claim according to the Ippisch Model as described would be misleading and untrue, if not impossible, since the non-sterile air and the dispensing mechanism inside of the housing, i.e. the rollers 26 , cutter 22 , dispensing receptacle 16 , discharge aperture 18 , spool of floss 19 , dispensing aperture 20 with which the floss 12 and 19 come into contact are not being maintained in a sterile environment according to the Ippisch model. Thusly, any sterile floss or medical/dental cordage loaded into the "unsterile" environment of the Ippisch apparatus would be rendered unsterile after only a short period of time. In order to remedy this situation, Floss-o-Mat contains an internal sterilization system.
