ABSTRACT:
The cartridge is made of plastic material and comprises a shell having an exit slot and end covers mounted at the ends of said shell. The cartridge consists of three substantially semicylindrical members, which by means of two hinges are connected to each other so that two semicylindrical members when folded together constitute a shell which encloses the roll of film and the third semicylindrical member covers said shell and defines a film passage in the shape of an arc of a circle, and the exit slot of the cartridge, and the two outer semicylindrical members are interconnected.
