Abstract
A filamentary article (8) free of silk-like fibers is disclosed, made out of an elastomeric material for use in dental hygiene. The article (8) is stretchable for proportionately reducing its cross section so that a sector (1) thereof, can enter between the teeth. The article (8) provides cuts along the edge, is twisted, or knotted at predetermined intervals along its length for furnishing radially directed edges or surfaces to help wipe food remanants, when longitudinally drawn through the larger interproximal openings, usually found in between teeth near the gums.
Claims6
A filament comprising a slender structure and a generally uniform rectangular cross section for cleaning interproximal spaces between teeth and gums;
- said cross section comprising a narrow side determining its thickness and a wider side determining its width;
- wherein said filament is free of silk-like fibers, for cleaning teeth without leaving fibers behind;
- said filament being made out of an elastomeric material so it can be soft to gums and be stretchable for easy insertion between teeth along its narrow side;
- while its wider side wipes over the teeth of the interproximal space;
- and wherein said filament is further comprising surface discontinuity means in terms of cuts at least along a lower edge;
- thereby, such cuts providing edges which are effective in brushing out food remnants, especially in large interproximal spaces near the gums.
A filament comprising a slender structure and generally uniform cross section used in oral hygiene for cleaning interproximal spaces between teeth and gums;
- wherein said filament is free of silk-like fibers, for cleaning teeth without leaving fibers behind;
- said filament being made out of an elastomeric material so it can be soft to gums and be stretchable for easy insertion between teeth;
- wherein said filament further comprises releasable knot means at predetermined intervals along its length for providing wiping action to food remnants, as said filament is longitudinally drawn through larger interproximal openings, usually found in between teeth near the gums;
- wherein said releasable knot means can be made during manufacture at any point of said filament without the need of cutting said filament for passing ends through filament bights;
- thereby enabling easy manufacture of said filament of any desired length.
