  • Patent number: 7325556
    Abstract: This invention has two components, a side delivery spray wand and a transparent plastic package with two compartments. One compartment serves for storage and display of the spray wand, and for guiding and limiting the wand's use in delivering the spray to the paint roller surface. The other compartment serves for storage and display of a paint roller, and is the protective chamber within which a roller is cleaned and spin-dried. The enclosure possesses a small top opening for insertion of the spray wand, and a bottom opening for rapid exhaust of paint-laden solvent. Its two halves are hinged, book-like. When open multiple units nest conveniently. When closed, the compartments are completed, a segment of a paint roller handle is captured, and the seam seals to force all of the paint laden solvent to vent at the exit port.

  • Patent number: 6116255
    Abstract: Disclosed herein is an apparatus whereby a paint roller can quickly be cleaned, fluffed, and rendered damp-dry with the operator and cleaning area completely shielded from the splatter of solvent and paint. The washing and spin drying actions are produced by a high velocity single jet of water or other solvent delivered through a hand-held spray wand within the confines of a hand-held, tapered cylindrical enclosure.The enclosure is open at the top for insertion of both the paint laden roller and the spray wand, and for visual access into the cleaning process. It's in-rolled upper rim eliminates egress of random splatter. It's open bottom affords rapid exhaust, and being tapered throughout, permits enclosure elements to be nested for efficient quantity packaging. The detachable handle, when affixed to the enclosure and properly adjusted, accommodates nearly any paint roller handle design.
