AI Technical Summary

Technical Problem

Existing dental floss has limited effectiveness in cleaning teeth, especially round dental floss. Furthermore, the material of traditional flat single-fiber dental floss is controversial and its cleaning quality is insufficient, which may cause wear and tear on teeth.

Method used

The structure is formed by interlacing at least three filaments along the same plane to form a flat structure. The interlacing method is that each filament is folded from one side to the other and alternately passes through the bottom or top to form undulating concave and convex parts. The material is nylon, polyester, polyethylene or polypropylene and may be coated with a lubricating substance.

Benefits of technology

It increases the friction area between the dental floss and teeth, improves the cleaning effect, reduces wear on teeth, protects dental health, and the concave-convex structure enhances cleaning ability.

Abstract

The utility model discloses a flat multi-cellosilk dental floss which at least comprises a first cellosilk thread body and a second cellosilk thread body, a second wire body; and a third thread body; wherein the first silk thread body, the second silk thread body and the third silk thread body are of a flat structure formed by interweaving the first silk thread body, the second silk thread body and the third silk thread body together along the same plane, and meanwhile, the utility model further discloses a tooth cleaning device applying the flat type multi-fiber-thread dental floss. The plurality of silk thread bodies are mutually interwoven together along the same plane to form the flat structure, so that the whole surface area of the flat type multi-fiber-thread dental floss is larger than that of a traditional cylindrical dental floss, the contact with the tooth surface is closer to surface contact, the friction area is increased, and the friction resistance of the dental floss is improved. And residues or dental plaque on teeth and in slits between the teeth can be better cleaned, so that the teeth are better protected.
