Abstract: The present invention is an improved vial-type floss dispenser. The floss dispenser has a spool of floss mounted upright in a cylindrical container with a unique cap design that allows floss to be smoothly dispensed through the cap of the dispenser, essentially parallel to the axis of the spool of floss. Tangling and snagging problems previously encountered with top-dispense floss vials of this type are avoided by the improved cap design that allows the free spinning of the spool within the container. The top-dispense mechanism of the present invention enables the use of a number of other improved features, including a protective lid that fully covers an exposed leader of floss between uses.
