Self-developing film pack with improved spread control structure

Image Number 2 for United States Patent #4226519.

A film pack, for use in a self-developing camera, including a film container having improved processing fluid spread control structure embodied in an extended forward wall portion of the container adjacent a film withdrawal slot to locate a spread control surface thereon in closer relation to a pair of pressure rollers in the camera. Although the forward wall is extended, the longitudinal dimension of the container, near its rear wall, has been maintained so that the improved pack will fit existing cameras. Also, the leading end wall of the container has been angled or sloped to improve the upward feed of film units toward an exposure position in the container. An alternative embodiment is disclosed.
