Abstract

A high quality toothbrush capable of preventing defective hair implantation such as cracking, whitening, warpage, and flat plate extraction from occurring at a head part in hair implanting though it is of a flat plate implanting type formed by densely implanting hair bundles in the head part , comfortably touching flexibly to teeth and gums, and easily advanced into small clearances. In this toothbrush, the hair bundles (5) formed by binding a plurality of pieces of brush hairs (6) are folded into two parts and implanted in implanting holes (3) in the implanted surface (2) of the head part (1) by using flat plates (4). The thickness (t) of the flat plate (4) is 0.10 to less than 0.22 mm, the width (h) thereof is 0.9 to 2.5 mm, the quantity of implanted hair bundles (5) per unit implant area is 25 to 80 bundles / cm<2>, and the total sum of the cross sections of the brush hairs (6) implanted for each implant hole (1) in a folded state is 1.0 mm<2> 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,...
