Abstract

Provide a flat-wire hair-planting toothbrush with high-density hair-planting of hair bundles, and provide a hair-planting defect that does not cause cracks or whitening, bending, and flat wires that do not fall off when the hair is planted, and is soft and tactile. Good, high-quality toothbrush with good penetration into small gaps. The bundle of hairs (5) bundled with a plurality of bristles (6) is folded in half with a flat wire (4) and planted in the hair-planting hole (3) of the hair-planting surface (2) of the head (1). (4) The thickness (t) is not less than 0.10 mm and not more than 0.22 mm, and the width (h) is not less than 0.9 mm and not more than 2.5 mm. The number of hair-planted hair bundles (5) per unit hair-planting area is more than 25 bundles / cm2 and less than 80 bundles / cm2, and the cross-sectional area of ​​the bristles (6) in the folded state for each hole of the hair-planting hole The sum of them is 1.0mm2 or less.

Description

technical field [0001] The invention relates to a flat-line hair-planting toothbrush which bundles a plurality of brush hairs into bundles, folds them in half with flat lines, and plants the hairs into the hair-planting holes on the hair-planting surface of the head. Background technique [0002] In the past toothbrushes, considering the production efficiency and the ease of flocking, in the flocking holes formed at intervals of more than 1.0 mm on the flocking surface of the toothbrush head, there will be an average of 16 to 60 bristles in each hole. 32 to 120 bristles, the sum of the cross-sectional area of ​​the bristles is 1.0mm 2 The above method makes the bristle bundles of thick hair bundles, and utilizes flat wires to drive in and fix. In the case of such a toothbrush, since the bristle bundles are thick and have high rigidity, the toothbrush has a characteristic of particularly high plaque removal power on a smooth surface or an occlusal surface. [0003] However,...
