Abstract
Dental floss loop devices are formed by a pair of parallel floss strands extending between and having their ends secured to a pair of spaced apart gripping elements. These devices are made by feeding a pair of continuous strands of floss from a source, molding onto these strands gripping elements at successively large and small intervals along the length of the strands, and cutting the strands at the small intervals. In a variation single gripping elements are molded onto continuous parallel strands at equal intervals afterwhich each single element is divided into separate halves, with the spaced apart halves being the pair of gripping elements for each device. The invention also includes dispenser packages for these devices.
