Abstract

Abstract The subject-matter of the invention is an implement for removing dental plaque and massaging gums in a form of a slender rod-like body of appropriate length comprising a fibrous structure obtained by bundling or bundling and bonding a plurality of fibers such as synthetic fibers in a longitudinal direction and a shell layer on the outer peripheral section of the fibrous structure. The shell layer is partly cut or ground to expose the fibrous layer in the interior thereof to form a brushing section. The fibrous layer may contain substances such as hygienically harmless alkali substances, surfactant, bactericide, deodorant, perfumes or the like.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 90 words
(1) A dental implement for removing plaque and massaging gums, characterized by forming, on the outer peripheral section of a fibrous structure obtained by bundling or bundling and bonding a plurality of fibers in a longitudinal direction, a shell layer having a greater physical strength at least as compared with that of the fibrous layer in the interior section to form a slender rod-like body of an appropriate length, then cutting or grinding the shell layer to expose the fibrous layer in the interior thereof to form a brushing section.
Claim 2
Dependent Claim 27 words
(2) A dental implement for removing plaque and massaging gums as described in Claim (1), characterized in that said shell layer comprises a tubular thermoplastic synthetic resin.
Claim 3
Dependent Claim 32 words
( 3 ) A dental implement for removing plaque and massaging gums as described in Claim (1), characterized in that said shell layer comprises a thermally melt-adhered fibrous layer of thermoplastic resin.
Claim 4
Dependent Claim 42 words
(4) A dental implement for removing plaque and massaging gums as described in Claim (1), characterized in that said shell layer comprises a synthetic fibrous layer and at least a layer of adhesive selected from thermoplastic synthetic resins or thermosetting synthetic resins.
Claim 5
Dependent Claim 30 words
(5) A dental implement for removing plaque and massaging gums as described in Claim (1), characterized in that the fibrous layer of the brushing section is formed from synthetic fibers.
Claim 6
Dependent Claim 32 words
(6) A dental implement for removing plaque as described in Claim (2), characterized in that the fibrous layer in the brushing section is formed from inorganic high molecular fibers or metal fibers.
Claim 7
Dependent Claim 38 words
(7) A dental implement for removing plaque and massaging gums as described in Claim (1), characterized in that the fibrous layer contains one or more kinds of hygienically harmless alkali substances, surfactant, bactericide, deodorant, perfume or the like.
