Abstract:

A material dispensing brush having a substantially rigid holding chamber and a resiliently, deformable bulb attached to the chamber for the purpose of pressurizing the same. The bulb is positioned proximate to the handle of the brush so that an operator may use his thumb to depress the bulb and thus increase the air pressure within the holding chamber so as to effect an ejectment of treatment material outwardly from the chamber through a plurality of dispensing orifices extending through the bristle retaining portion of the brush. The dispensing orifices have a truncated shaped portion proximate to the holding chamber so as to facilitate the delivery of the treatment material into the orifices during a pressurization of the chamber. A pressure relief hole is provided on the deformable bulb so that it may be quickly reinflated by the operator, simply by removing his thumb from the bulb, and the dispensing orifices are substantially aligned in a straight line within the same plane to permit an accurate and controlled dispensing of the treatment material.
