Abstract
A dental floss dispenser in a credit card format permitting the dispenser to be conveniently carried in a wallet. The dispenser comprises a base panel having a peripheral ridge to define a shallow well within which is nested a supply of dental floss in flattened coil form. The leading end of the coil passes out of the well through an aperture and is caught by a lug adjacent an edge notch cut in the base panel. Anchored in the well is a blade whose cutting edge is exposed by the notch, whereby when floss is pulled out of the well to provide a usable length, the trailing end thereof may be cut by the blade. The dispenser is completed by a face panel bonded to the ridge to encapsulate the floss supply, the face panel having a corresponding notch.
