Abstract
A disposable processing kit for use in developing a photographically exposed roll of instant type film. The kit includes first and second sections which are adapted to mate with each other so as to provide a chamber for enclosing a roll of flexible sheet material such that a free end thereof extends therebetween to the exterior of the kit. The first section includes means for supporting a package containing a supply of viscous processing liquid, a reservoir into which the processing liquid is adapted to flow upon rupturing of the package, and a nozzle for applying a layer of the liquid to one side of the sheet material as the latter is being withdrawn from the kit. The second section includes an integral resilient member which functions to press the sheet material against the nozzle during the spreading of the processing liquid on the sheet material, and to seal the nozzle after the sheet material has been rewound into the chamber thereby substantially sealing off any remainign liquid in the reservoir and the liquid coated sheet material from the exterior of the kit.
