Abstract
Abstract A closed, molded box for storing a videocassette includes an open sleeve, a cover and a living hinge connecting the sleeve and the cover, the hinge, the sleeve and the covering being molded simultaneously and integrally. The videocassette box may further include raised ridges on the cover and raised detents on the sleeve which engage to maintain the cover in its closed position. The cover may also include an inwardly directed protrusion adapted to contact a videocassette within the sleeve and prevent movement of the videocassette when the cover is closed.
