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.

The invention claimed is: 1. An internally fed paint brush comprising: a brush head having a plurality of filaments and an internal passageway in fluid communication with the plurality of filaments, the internal passageway including a fluid inlet; a handle that is removably connected to the brush head, the handle and brush head separable for cleaning; a latching mechanism configured to retain and selectively release the brush head from the handle; a reservoir and a siphon tube in the handle, the reservoir and siphon tube connected to draw paint from a lowermost region of the reservoir when the handle is generally horizontal and deliver paint to the brush head via the siphon tube and internal passageway of the brush head, the reservoir having an outlet and a fill opening, the siphon tube having a fluid outlet; a seal disposed on the reservoir, between the fluid inlet of the internal passageway and the fluid outlet of the siphon tube; a valve on the handle between the seal and the fluid outlet of the siphon tube, the valve opening when the reservoir is compressed and closing when the reservoir is not compressed; and a removable cap closing the fill opening, the fill opening providing fluid communication with the reservoir when the removable cap has been removed such that the reservoir can be filled with paint without removing the brush head from the handle; wherein the seal and removable cap permit the handle to be removed from the brush head without spilling paint from within the reservoir. 2. The paint brush of claim 1 wherein the seal has an O-ring portion connected to the valve. 3. The paint brush of claim 1 further comprising a vacuum breaker valve to prevent vacuum in the reservoir as paint is delivered from the reservoir to the brush head. 4. The paint brush of claim 1 wherein the latching mechanism comprises at least one ear on one of the handle and brush head and at least one mating aperture on the other of the handle and brush head wherein when the ear is received in the aperture the brush head is retained to the handle, and when the ear is displaced from the aperture, the brush head is released from the handle. 5. The paint brush of claim 1 wherein the handle has a pair of concave depressions on opposite sides of the handle sized and positioned to receive a thumb and a forefinger of a user grasping the paint brush. 6. The paint brush of claim 1 wherein the handle further comprises a hook and the brush head further comprises a recess, the hook and recess in combination providing a pivoting connection between the handle and brush head that aligns the latching mechanism.
