Abstract

A light-tight cassette (1) suitable for holding a roll of web-like light-sensitive photographic material (2) wound around a core (6) and for dispensing the photographic material through a slit (19) provided in the cassette which is in the form of a box comprising a hollow shell portion (3) whose wall at three of its corners is at least partly and locally realized as a double wall and two end closure walls (4, 5) which are secured to the shell portion (3) by perforations provided in the outer wall of the double wall portions of the shell and cooperating detent fingers on the end closure walls. The inner wall of the double wall portions of the shell prevents light from intruding into the cassette through perforations in the outer shell wall and makes the cassette perfectly light-tight.
