Abstract
A disposable kit of the type adapted for use in film processing apparatus in the processing of a roll of exposed instant type transparency film, preferably of the 35 mm format. The kit includes a two-section housing which encloses a roll of sheet material, a container of processing liquid and a nozzle dispenser to apply a coating of the liquid to one side of the sheet material as it is being drawn from the housing prior to being laminated to a length of exposed film. After the appropriate length of sheet material is withdrawn from the kit and the processing cycle is completed, the strip of sheet material is retracted into the kit. A fluted idler roller is mounted in the housing to minimize the sideward migration of any processing liquid remaining on the sheet material when it is retracted into the kit.
