Abstract
Weatherproof portfolios which are integral moldings of a thermoplastic polymer forming an elongated spine having a first side panel and a second side panel respectively hingedly mounted on respective, opposite, longitudinal edges of said spine, each panel having two integrally molded side flanges connected by an integrally molded top flange to form two, respective, substantially identical enclosures on respective panels, the longitudinal edges of said two side flanges and said top flange of the respective enclosures being aligned when said side panels are swung about their hinges from an open position toward each other and into abutting contact in the closed position, and grooves in the longitudinal edges of the side and top flanges on one side panel and longitudinal mating tongues or ribs on the longitudinal edges of the side and top flanges of the other side panel to provide substantially weathertight seals when the portfolio is closed.
