  • Patent number: 5452033
    Abstract: A recyclable, single use photographic film package and camera comprising a light-tight camera mechanism having a frame forming exposure gate, a roll of unexposed film withdrawn from its cartridge and pre-wound on a film takeup spool disposed on one side of the exposure gate, the cartridge disposed on the other side of the exposure gate, and an externally operable film winding thumbwheel for winding the filmstrip through the exposure gate and back into its cartridge as the film is exposed frame by frame. When all frames are exposed, the exposed film is removed and processed, and the package is recycled by substituting a fresh film cartridge and new packaging for resale. To prevent unauthorized reuse of the camera mechanism by refilling it with other than genuine film, a component of the takeup spool is intentionally damaged upon winding the last image frame into the film cartridge.
