  • Patent number: 6499177
    Abstract: A novel end cap assembly for attachment to a commercially available paint roller assembly allows the application of a coating material, such as paint, uniformly to two intersecting surfaces such as in a corner. The inventive end cap comprises a unitary disc like base having a prong projecting laterally therefrom, the base and prong being formed unitarily from a suitable polymer. A textured material such as fabric, open celled foam, or sheepskin bearing natural wool is adhered to the base. A single prong engages a space existing between the inner surface of the roller cover and the outer surface of the roller frame barrel so that the possibility of damage to the possibly damp paper tube of the roller cover is avoided when the end cap is installed. The prong is straight where joined to the cap at its proximal end, and is curved at its distal or free end. The prong is formed from a material imparting spring qualities.
