摘要： The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member connected to a toothbrush head member. The head is divided into two regions. A "toe" region is defined as the part of the head which is furthest from the handle and a "heel" region is the portion of the head which is closest to the handle. A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end. Likewise, a multiplicity of bristles extend from the toe region of the head, wherein said bristles extending from the toe portion of the head are at least as tall as the general height of said bristles extending from the heel portion when viewed from the side and wherein the side profile view of the distal ends of the bristles extending from the toe portion form a generally linear surface which forms an angle relative to the general plane of the bristles extending from the heel portion of from 0.degree. to about 45.degree. declining from the edge of the toe portion distal to the heel portion to the edge of the toe portion which is proximal to the heel portion.

摘要翻译：本发明涉及牙刷，其显示出优异的邻间和牙龈边缘清洁。牙刷包括连接到牙刷头部件的细长手柄部件。头部分为两个区域。 “脚趾”区域被定义为距手柄最远的头部的一部分，并且“跟部”区域是头部最接近手柄的部分。多个刷毛从头部的跟部区域延伸; 当从末端看时，这些刷毛的远端形成纵向对准的凹形。类似地，多个刷毛从头部的趾部区域延伸，其中从头部的趾部延伸的所述刷毛至少与从侧面观察时从后跟部分延伸的所述刷毛的总高度一样高，并且其中从趾部延伸的刷毛的远端的侧剖视图形成大致线性的表面，其相对于从0°至约45°的跟部延伸的刷毛的总平面形成一角度，从0°至约45°的边缘的脚趾部分远离脚跟部分到脚趾部分的靠近跟部部分的边缘。
