刷子，特别是牙刷，以及相关的生产方法
Brush, in particular toothbrush, and associated production method
US-8109686-B2用于清洁，可释放活性物质。
专利摘要
一种刷子，特别是牙刷，包括具有清洁结构的头部，该清洁结构带有刷毛，手柄部分和颈部部分，在头部或颈部中具有带有至少一个用于活性物质的出口的腔体。在一个实施例中，腔体包含活性物质元件，该元件在载体材料中含有活性物质，并在与水接触时以受控方式释放该物质。在另一个实施例中，腔体通过限定的外部轮廓适应活性物质元件的形状。腔体的体积优选为活性物质元件体积的1-2倍，且不超过4倍，确保在使用过程中活性物质元件优选被水包围。这使得活性物质能够有效计量，并确保刷子易于使用。

In one embodiment, the cavity incorporates an active substance element, which contains the active substance in a carrier material and releases the substance in a controlled manner when it comes into contact with water. In another embodiment, the cavity is adapted to the shape of an active substance element by means of defined external contours. The volume of the cavity is preferably 1-2 times and no more than 4 times greater than the volume of the active substance element, ensuring that the latter is preferably surrounded by water during use.
