    • The invention relates to a brush, in particular a toothbrush, comprising a head part (10) with a cleaning structure (12) that comprises bristles (14), a hand part (62) and a neck part (52), a cavity (22) comprising at least one outlet opening (36) for an active substance being located in the head or neck part (10, 52). In one embodiment, the cavity incorporates an active substance element (24), which contains the active substance in a carrier material and releases said substance in a controlled manner when it comes into contact with water. In another embodiment, the cavity (22) is adapted to the shape of an active substance element (24) by means of defined external contours. The volume of the cavity (22) is preferably 1-2 times and no more than 4 times greater than the volume of the active substance element (24), ensuring that the latter is preferably surrounded by water during use. This allows the active substance to be effectively metered and ensures that the brush is easy to use.
    • 刷具有具有刷毛(14)的头部(10),其中头部或颈部是具有用于主动清洁物质的出口(36)的中空区域(22)。 中空区域与具有限定的外部形状的活性物质元件(24)的形状匹配。 中空区域的体积比活性物质元素的体积更大,优选最多达4倍,使得在使用过程中用水在所有侧面上冲洗。 刷子优选在中空区域的区域中是柔性的,使得刷子在使用过程中变形,并且水被吸入和移出中空区域。 独立权利要求描述了通过在硬组分中提供中空区域来制造刷子的方法。
