Abstract: A brush having a bundle of bristles connected to a handle and being provided with a chamber to be filled with a liquid material is disclosed. The chamber includes pressurizing means for maintaining the liquid material under continuous pressure and closure means for preventing the liquid material from flowing from the chamber to the bristles. The chamber is also integrally connected with the brush and is connected to the bundle of bristles in a liquid-conductive relationship by means of a tubular conduit. The bundle of bristles is set into a separate head mounted for sliding movement on the handle, thereby rendering the conduit and bundle axially slidable relative to each other between a first use position and a second filling position.
