  • Patent number: 3933401
    Abstract: The rear and side panels of a drawer are formed from a single slab of foamed rigid poly(vinyl chloride) having a reinforcing densified core and a densified outer skin with a wood grain pattern thereon. A longitudinal groove is formed in one surface of the slab adjacent the bottom edge thereof, and two V-shaped grooves are cut across the width of the same surface at appropriate ultimate corner forming locations. Appropriate guide slots and drawer front fastening configurations are formed on the slab. The slab is heated and bent at the V-shaped groove locations to form the rear and side panels of the drawer. A drawer bottom panel is installed in the longitudinal groove adjacent the bottom edge of the rear and side panels and the drawer front is attached. The drawer looks, feels, sounds, and handles like wood, but is less expensive and has many desirable qualities not possessed by wood.
