    Abstract: A toothbrush comprising a head having a flat surface facing upwardly, the head joined to a handle. The tufts of bristles are arranged in two groups of rows, each row extending transversely of the head. The rows of the first and second groups alternate with each other along the longitudinal axis of the head. In the first group, the two laterally outermost tufts of each row tilt sidewise towards their respective nearest side of the head, this tilt being about 12 degrees. The middle tuft of each of the second group extends substantially vertically upwardly from the head. The laterally outermost tufts of the second group tilt laterally inwardly toward each other by about 8 degrees. The tufts define three functional groups of tufts. The tuft arrangement is such that the cleaning action is substantially independent of any particular brushing technique employed by the user.

    Abstract: A toothbrush whose tufts comprise three distinct groups of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first group are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third group are nearest the end of the head farthest from the handle and diverge from each other. In one embodiment, each tuft of the third kind tilts laterally at an angle of about 30 degrees and forwardly at about 14 degrees. In a first embodiment, each row of the first group comprises a single, wide tuft. In a second embodiment, each row of the first group has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first group comprises a plurality of laterally spaced quadrangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing. The arrangement and orientation of the tufts yields a uniform cleaning action substantially independent of brushing direction or technique.

    Abstract translation: 一种牙刷，其刷毛簇包括三组不同的排，其中每排横向于头部的纵向轴线。 第一组的簇数最短。 第二种类型的每一行的最末端的一束向外横向倾斜大约12度。 第三组的簇最接近离手柄最远的头部，并彼此分开。 在一个实施例中，第三类的每个簇以横向方向以约30度的角度倾斜并以约14度向前倾斜。 在第一实施例中，第一组的每一行包括单个宽的簇。 在第二实施例中，第一组的每一列具有多个横向间隔的圆形簇。 在第三实施例中，第一组的每一行包括多个横向间隔开的四边形簇。 所有的簇也可以被认为是定义簇的四个功能组，这四组中的每一个在刷牙过程中都具有特定的功能。 刷毛束的布置和取向产生基本上与刷洗方向或技术无关的均匀的清洁作用。
