Abstract

Improvements in protectors for photographic film reels, characterized by comprising two semi-cylindrical halves of a body, made of light-proof material, each with its end walls provided with semicircular openings in their centers, prepared to receive the core of a film reel and with inter-adjustable tabs and grooves, at the radial edges of said walls; one of the halves has a tangentially arranged edge, and the other a tangentially opposite edge; the edges leave between them a narrow slot for the passage of the film; edge surfaces have mutually adjustable tabs and grooves; These protectors have the halves of the body joined by an integral, thin and flexible hinge, which extends over the entire length of them.
