    • A toothbrush (10) includes a head (14) having a bristle carrying surface formed from a thin flexible dome shaped membrane (24). An air space (28) is located between the base of the head and the membrane so that the membrane can be capable of flexing to alter its shape during use and then resuming the original shape. In a second embodiment, the head (114) and/or handle (112) have elastomeric portions at least partially surrounding an open area. These portions are readily deflectable under pressure during use to improve handling of the toothrush and orientation of the cleaning elements (124). Alternatively the toothbrush includes a resilient spring-like longitudinal hinge (222) collinear with the longitudinal axis of the toothbrush head so as to separate the head into a pair of side by side longitudinal sections having extending cleaning elements (228) wherein the hinge urges the sections to return to their original position after the hinge has been opened as a result of the cleaning elements contacting teeth.
    • 牙刷(10)包括具有由薄柔性圆顶形膜(24)形成的刷毛承载表面的头部(14)。 空气空间(28)位于头部的基部和膜之间,使得膜可以在使用期间能够弯曲以改变其形状,然后恢复原始形状。 在第二实施例中,头部(114)和/或手柄(112)具有至少部分地围绕开放区域的弹性体部分。 这些部分在使用期间在压力下易于偏转,以改善牙刷的处理和清洁元件(124)的取向。 或者,牙刷包括与牙刷头的纵向轴线共线的弹性弹簧状纵向铰链(222),以便将头部分离成具有延伸的清洁元件(228)的一对并排的纵向部分,其中铰链促使 由于清洁元件接触牙齿,铰链已经打开之后返回到其原始位置。

    • A toothbrush, either manual or powered, including an elongated member with a head at one end and a handle at the other end. The toothbrush is generally aligned along a central longitudinal axis. The head having a brush face including a brush cavity from which a plurality of bristles extend. The bristles being arranged in a plurality of bristle tufts so as to extend generally perpendicular to the central longitudinal axis. The toothbrush also includes a plurality of lateral support members extending upwardly from a base of the brush cavity. The bristles are attached to the toothbrush by an attachment device provided in the brush cavity. The attachment device engages at least one of the tufts and secures the tuft between adjacent lateral support members. The attachment device includes a bottom edge and a top edge. Each of the lateral support members extend to a predetermined height from the base of the brush cavity so as to reach at least the height of the bottom edge of said attachment device in the brush cavity.
    • 一种手动或动力的牙刷,包括在一端具有头部的细长构件和另一端的手柄。 牙刷通常沿着中心纵向轴线对准。 头部具有包括多个刷毛延伸的刷腔的刷面。 刷毛被布置成多个刷毛簇,以便大致垂直于中心纵向轴线延伸。 牙刷还包括从刷腔的基部向上延伸的多个侧向支撑构件。 刷毛通过设置在刷腔中的附接装置附接到牙刷。 附接装置接合至少一个刷毛束并且将刷毛束固定在相邻的横向支撑构件之间。 附接装置包括底部边缘和顶部边缘。 每个侧向支撑构件从刷腔的基部延伸到预定高度,以便至少达到刷腔中所述附接装置的底部边缘的高度。
