A cassette constructed to serve as a film holder for X-ray film or the like. The cassette is a rectangular container or box having a hinged cover, hinged by way of a piano type hinge and having a catch member opposite the hinge for holding the cover in closed position. A light trap is provided around the peripheral edges of the box and cover to make the container light tight. Preferably the hinge and catch members are fabricated from continuous metal strips.
