    • A toothbrush includes a head having a bristle carrying surface formed from a thin resilient flexible dome shaped membrane. An air space is located between the base of the head and the membrane so that the membrane is capable of flexing to alter its original shape during use of the toothbrush and then recover to the original shape randomly during use. In a further practice of the invention the head and/or handle have elastomeric portions at least partially surrounding an open area. These portions are readily deflectable under pressure during use to improve handling of the toothbrush and orientation of the cleaning elements. Alternatively the toothbrush includes a longitudinal hinge collinear with the longitudinal axis of the toothbrush head so as to separate the head into a pair of side by side longitudinal sections, each of which has outwardly extending cleaning elements. The hinge is made of a resilient spring-like material to urge the sections to return to their original position after the hinge has been opened as a result of the cleaning elements contacting the teeth.
    • 牙刷包括具有由薄弹性弹性圆顶形膜形成的刷毛承载表面的头部。 在头部的基部和膜之间设置有空气空间,使得膜在使用牙刷期间能够弯曲以改变其原始形状,然后在使用期间随机恢复到原始形状。 在本发明的进一步实践中,头部和/或手柄具有至少部分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容易偏转,以改善牙刷的处理和清洁元件的取向。 或者,牙刷包括与牙刷头的纵向轴线共线的纵向铰链,以将头部分离成一对并排的纵向部分,每个纵向部分具有向外延伸的清洁元件。 铰链由弹性弹簧状材料制成,以便在清洁元件接触牙齿之后铰链已经打开之后促使部件回到其原始位置。
