A pack of photo-identification cards comprises a casing including an exposure aperture and an exit slot and containing a plurality of photo-identification cards. Each card includes an exposable film chip surrounded by a core spacer and laminated with a transparent cover panel to substantially entirely surround the film chip except for access and venting ports through which processing fluid can be introduced to the film chip and air can be displaced from the volume occupied by the fluid.

Photo-identification card pack

A photographic film unit, which includes a photosensitive sheet and a cover sheet separated by a spacer, is provided with a small access port for introducing a processing fluid from the exterior of the film unit into the space between the sheets and a small venting port for releasing air displaced from such space by the introduction of the processing fluid. The spacer surrounds substantially the entire edge perimeter of the film unit in a border area thereof. The access and venting ports extend through the spacer in this border area at diagonally opposite corners of the film unit.

Instant film unit

In a photographic film unit having a pair of sheets connected in superposition with a photosensitive layer located between the sheets, a container carrying a quantity of fluent processing composition is arranged to provide for the discharge of the composition to between the sheets. A fluid receiver or trap is provided at the opposite edge of the sheets to receive and store excess processing composition after it has been spread between the sheets. The improvement comprises a trap construction wherein an intermediate sheet, which is disposed between the pair of sheets and is coupled to both of them, extends from between the pair of sheets at the trailing end thereof and is folded around one of the sheets at that end to form a trap cover over the trap volume between that folded portion and the outside surface of that one sheet. Spacing elements are formed by embossing the trailing end of that one sheet and fluid flow slits are formed by slitting the trailing edge of that sheet. The spacing elements assure a minimum trap size since the excess processing composition can be accommodated between the convex portions thereof and the trap cover as well as in the concave portions thereof between the pair of sheets.

Fluid receiving trap

A photo-identification card comprises a plastic laminate permanently encasing a photographically-exposable film chip that is developable by a single processing fluid. The laminate includes a core spacer having a compartment for receiving the chip with the spacer surrounding substantially the entire edge perimeter of the chip. Transparent cover panels, fused to the spacer by plastic-to-plastic bonds, physically protect the chip while permitting exposure and viewing through the laminate. Access ports are provided leading from the exterior of the laminate to the compartment for delivering the processing fluid to the chip.
