ABSTRACT:
A self-processing film unit, including a sheet-like photosensitive film component, is provided with a liquid applicator holding a supply of a low viscosity procesing liquid that is to be applied to a given area of an outer surface of the film component, following its exposure, to initiate processing. The applicator includes a folded and releasably sealed enclosure section having therein liquid holding means, such as an absorbent pad soaked with the liquid, a leader tab forming section between one end of the film component and the enclosure section, and a mechanical ground section. In response to applying a longitudinally directed compression force on the film unit, the leader tab forming section folds to form a protruding leader tab. When a tension force is applied progressively to the leader tab and then following portions of the film unit, the ground section provides an appropriate reaction force for effecting the unsealing of the enclosure section and its movement to an extended position to bring the soaked pad into liquid yielding contact with the film component outer surface.
