Abstract
A fluid dispensing brush head includes bristles whose base portions engage apertures in a resilient member to create seal which is disrupted when the bristles are deflected as in use to selectively dispense a fluid. The bristles may be affixed to or form part of a unitary bristle carrier which, along with the resilient member, is removably secured to the body of the brush head so as to permit the brush head to be disassembled and thoroughly cleaned.
