摘要：A dental floss applicator of this invention comprises a housing, a dental floss stick, a floss spool, a spring rack, a take-up wheel, and a rotary knob with a springy ratchet on the inside. The spring rack has a stop portion engaged with a gear wheel fastened to the floss spool to stretch the dental floss, and a press portion extending to the outside of the housing for pressing by the user to loosen the dental floss on the dental floss stick. The springy ratchet releases the stop portion of the spring rack step by step upon rotation of the rotary knob, allowing the used segment of the dental floss to be taken up.
