Abstract: front page image
(EN)An interdental brush is provided which can be easily inserted between the teeth. This interdental brush has a handle part 10, a core part 20, and a brush part 30. The core part 20 extends in a straight line from the handle part 10. The brush part 30 is formed from multiple filaments which extend from the core part 20 in a direction that intersects the direction of extension of the core part 20. The brush part 30 includes n filament bundles (n being an integer greater than or equal to 3) which are formed from single groups of filaments continuous along the direction of extension of the core part 20. The interval between the filament bundle 33 nearest the tip 20a of the core part 20 and the adjacent filament bundle is wider than the average interval of the n filament bundles.
(FR)L’invention fournit une brosse interdentaire facile à insérer entre les dents. Cette brosse interdentaire (1) est équipée d’une partie manche (10), d’une partie âme (20) et d’une partie brosse (30). La partie âme (20) se prolonge sous forme de droite à partir de la partie manche (10). La partie brosse (30) est constituée d’une pluralité de filaments se prolongeant à partir de la partie âme (20) dans une direction croisant la direction de prolongement de celle-ci. La partie brosse (30) inclut n faisceaux de filaments (n étant un nombre entier supérieur ou égal à 3) constitués d’un groupe de filaments continu dans la direction de prolongement de la partie âme (20). L’intervalle entre le faisceau de filaments (33) le plus proche d’une extrémité avant (20a) de la partie âme (20) parmi les faisceaux de filaments et le faisceau de filaments le plus éloigné, est plus large que l’intervalle moyen entre les n faisceaux de filaments.
