ABSTRACT:
A motion picture film reel is constructed so as to be readily disassembled into its component parts to permit film to be removed therefrom without breaking the component parts of the reel. Furthermore, the component parts of the film reel can be rapidly reassembled for repeated reuse. Moreover, the structure is completely plastic so that it may be melted down and is totally recyclable. The film reel is comprised of a pair of side retainers that are releasably engaged with a disk-shaped hub. Each of the side retainers has a pair of posts with catches on the ends thereof which may be inserted through post receiving apertures in a transverse web in the hub. The posts are also provided with cam surfaces which interact with each other to hold the catches engaged with the web. A latching mechanism immobilizes the side retainers relative to each other and relative to the hub until or unless released.
