  • Drip collar for a paint brush
    Patent number: 5084932
    Abstract: A removable drip collar for a paint brush to prevent paint from running back over the handle of the paint brush and also to prevent paint from flowing to the proximal ends of the brush bristles. The collar includes an elastomeric sleeve which tightly fits around the brush handle and extends over a portion of the brush bristles to tightly compress the proximal ends of the bristles together to create a liquid-tight seal between adjacent bristles and between the bristles and the sleeve.
