    摘要： A toothbrush having a handle a head extending from the handle, and a plurality of tufts of bristles secured to the head. One of the tufts is secured to the head at a location such that no other tuft is secured to the head at a location which is more distal from the handle than the location where the one tuft is secured to the head. The one tuft is angled by about 81 degrees or less relative to an imaginary line which is tangent to or co-planar with a surface of the head through which the one tuft is secured to the head. The one tuft is tilted away from the handle towards a direction along which the head extends from the handle.

    摘要翻译： 具有从手柄延伸的头部的手柄的牙刷和固定到头部的多个刷毛簇。 其中一个刷毛束在一个位置被固定到头部，使得在距离手柄更远的位置处，没有其他刷毛簇固定到头部，而该位置比一个绒头固定到头部的位置更靠近头部。 相对于与头部的表面相切或共面的假想线，一个簇与所述头部固定在头部上的角度相差约81度或更小。 一个毛簇从手柄向着朝向头部从手柄延伸的方向倾斜。
