チャネルの凹状の湾曲部の半径58:0.01mm
凹状の湾曲部の半径58に対する外径56の比率:29.5
突起部の先細りα:15°
突起部の湾曲部の直径62:0.04mm
半径58に対する直径62の比率:4
内径64:0.1mm。
外径28:0.309mm
凹状の湾曲部の半径30:0.06mm
凹状の湾曲部の半径30に対する外径28の比率:5.15
突起部の先細りα:10°
突起部42の湾曲部の直径42:0.04mm
半径30に対する直径42の比率:0.67
内径70:0.12mm。
ロボット試験:
複数のフィラメント68(例示的な実施形態1)を備えた図4に示される毛束66(毛束の直径:1.7mm)、複数のフィラメント74(比較実施例2)を備えた図5に示される毛束72(毛束の直径:1.7mm)、及び複数のフィラメント54(比較実施例3)を備えた図6に示される毛束76(毛束の直径:1.7mm)を、人工歯(typodont)上での代替的歯垢除去のそれらの効率に関して比較した。
図8は、本開示に基づき、かつ約46%の詰込み率を有するフィラメント(例示的な実施形態4)を備えた毛束(毛束の直径:1.7mm)の「スラリー取り込み質量」を、約80%の詰込み率を有する(比較実施例5)ダイヤモンド形状のフィラメント(図10参照)を備えた毛束(毛束の直径:1.7mm)の「スラリー取り込み質量」及び比較実施例2による毛束72の「スラリー取り込み質量」と比較した図を示す。
外径:0.269mm
チャネルの凹状の湾曲部の半径:0.05mm
凹状の湾曲部の半径に対する外径の比率:5.38
突起部の先細りα:14°
突起部の湾曲部の直径:0.029mm
チャネルの凹状の湾曲部の半径に対する、突起部の湾曲部の直径の比率:0.58
内径:0.102mm
長い方の対角線長さ92:0.29mm
短い方の対角線長さ94:0.214mm
例示的な実施形態4並びに比較実施例2及び5による毛束を備えるブラシヘッドを、フィラメントが下向きに尖った水平位置において固定した。練り歯磨きスラリーの皿(練り歯磨き:水=1:3)を、はかりと共に、ブラシヘッド直下に定置させた。このスケールを用いて、皿内のスラリー量を測定した。試験が開始されると、ブラシは100mm/秒で下方に移動し、かつスラリー中に2mmの深さで浸液した。次に、ブラシを練り歯磨きスラリー中で5秒間保持して、再び100mm/分で引き上げた。この垂直方向の力を、経時的に測定した。
