审中-公开
具有进步和张力调节机制的牙科睫毛膏
摘要：
A handle houses a dental floss supply reel and a dental floss take-up reel in separate chambers. Movement and tension of a single long strand of dental floss through a pair of arched flossing arms is controlled by a new dental floss supply control knob, and a used dental floss take-up control knob. Spring loaded ratchets control the action of the reels. A hygienic cover protects the flossing arms. A small brush stored in the cover cleans the used dental floss of debris.
