Abstract:

A disposable film developing assembly comprises a container having a developing chamber and an additional chamber upstream thereof for receiving a film wrap. A developer envelope containing film treating fluid is disposed inside the container, tabs on the envelope being connected to the container for tearing open the envelope and permitting the release of fluid therefrom upon a withdrawal of the envelope from the container. Linking elements for coupling a film to the envelope are provided, whereby the film is drawn from the film wrap into the developing chamber during a withdrawal of the envelope from the container. The envelope has a fluid containing pocket with a pair of longitudinally staggered extensions projecting from the longitudinal edges of the envelope towards the longitudinal edges of the container. Tabs are connected to the envelope at the extensions of the envelope pocket and are folded at creases over the respective extensions. Each tab is provided with a respective cut and is torn along a line extending from the cut through the respective extension.
