  • Brush
    Patent number: 6745427
    Abstract: The invention relates to a brush, especially a toilet brush, comprising a brush head and a brush head holder, wherein the brush head can be detachably mounted on the brush head holder, especially in such a way that the two interlock. According to the invention, the brush head can be slid onto the brush head holder with a friction fit. It is therefore possible to exchange a used brush head for a new, germ-free replacement. This not only avoids the unattractive appearance that conventional brushes acquire after repeated use, but also prevents health risks to the user.
