| description | A light-tight cassette for holding and dispensing a roll of light-sensitive material and comprising an extrusion moulded shell or casing (11) and injection moulded end caps (12,13). Difficulties which may arise in fitting the end caps upon the ends of the shell are avoided by providing the inner face of the end caps with axially projecting corner tongues (26,27,28) shaped in a three-dimensional form having outwardly facing surfaces which are outwardly convexly curved both in radial planes passing through the axis of the hub portion (44) of the cap and in planes normal to said axis. These corner tongues fit inside corner regions of the shell and have a self-centering action when the caps and shell are pushed together in abaxial and/or relatively angularly skewed relationship. |
