Abstract
A fountain brush has a bristle carrier and a set of bristles on one end thereof, a handle attached to the other end of the bristle carrier and a reservoir a channel extends axially through the bristle carrier from the reservoir into the bristle-bearing end of the carrier; the channel has at least one radial outlet orifice in the sidewall of the carrier. A slide valve member is guided sealingly in the interior of the channel. A closure member is adapted for hermetically closing the reservoir. A connecting rod extends substantially axially through the interior of the reservoir and connects the actuating device and the slide valve member to one another. The closing member is at such distance from the slide valve member that, in a filling position in which medium can be filled into said reservoir, the closing member leaves the open end of the handle free while the slide valve member seals off the reservoir; an elastically deformable bellows is connected hermetically sealingly with the closing member, and with the inner wall of the handle, in actuated as well as in unactuated position of the actuating device, thereby closing the reservoir; the slide valve member obturates the orifice when in the said unactuated position and, upon actuation by pressure on the closing member, is moved into the blind end of the channel past the orifice clearing the latter.
