Abstract
A manually operated internally fed paint brush having a resilient handle forming a refillable paint reservoir and a brush head with a fluid delivery path connecting the reservoir to the brush head via a siphon tube having an inlet positioned at a lowermost region of the reservoir when the paint brush is generally horizontal. A combined valve and O-ring seals an outlet of the siphon tube and selectively opens in response to compression of the reservoir. A latching mechanism retains the brush head to the handle. A trough having a spout is provided for filling the paint brush.
