Title: Tensioning device for a dental flossing apparatus

Abstract: The present invention is an improved tensioning mechanism for use in a dental flossing apparatus. The dental flossing apparatus is used in conjunction with a dental floss container, which has an inner lip and which contains a spool of dental floss. The tensioning mechanism includes a first elongated member and a second elongated member, each of which has a first end and a second end and each of which has a raised tip-portion at its second end which has a hole disposed perpendicularly thereto and adapted to receive the dental floss therethrough. The second elongated member is formed so that it is pivotally coupled to the first elongated member in a scissor-like manner the raised tip-portions of the first and second elongated members will separate from each other when their first ends are brought together. The tensioning mechanism also includes a dispensing mechanism for controlling the dispensing of dental floss from the dental floss container. The dispensing mechanism includes a shaft, which is adapted to be forceably engaged into the dental floss spool, a disc, which is adapted to travel along the inner lip of the dental floss container and which is fixedly coupled to the shaft, and a spool, which is adapted to receive used dental floss and which is mechanically coupled to the shaft by means of a ratchet assembly, which permit rotation in only one direction.
