Abstract
A flat, dental floss dispenser in a credit card format having a flat coil of floss in a well within the dispenser. A cutting blade is formed as a tab projecting from a plate which is supported on a step projecting from the well bottom inside a peripheral edge. Wall members project from the well bottom and surround at least a portion of the plate. The blade is a substantially U-shaped tab raised from the plate and forms two spaced acute angular intersections at its line of intersection with the plate, one being larger than the other. The larger functions to cut the floss, and the smaller to retain the cut end on the dispenser. The supply coil has a wrapping to assist in maintaining its integrity during manufacturing and in the dispensing process and the floss is withdrawn through the center of the coil.
