  • 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.
