摘要： FOR TRAPPING AND RETAINING THE EXCESS PROCESSING FLUID DISTRIBUTED BETWEEN AN EXPOSED PHTOTSENSITIVE SHEET AND A SECOND SHEET SUPERPOSED THEREWITH WHEN THE TWO ARE MOVED LONGITUDINALLY BETWEEN A PAIR OF PRESSURE APPLYING MEMBERS TO RUPTURE A POD CONTAINING AN AMOUNT OF PROCESSING SOLUTION IN EXCESS OF THAT REQUIRED TO PROCESS THE EXPOSED LATENT IMAGE, THE TRAILING END OF ONE OF THE SHEETS IS EXTENTED BEYOND THE IMAGE AREA THEREOF AND IS MEDIALLY FOLDED BACK UPON ITSELF TO PROVIDE A FLAP THE FREE END OF WHICH WILL EXTEND BACK AT LEAST TO THE TRAILING END OF THE OTHER SHEET, AND PROBABLY BEYOND AND UNDER THE TRAILING END OF THE OTHER SHEET, TO FORM A TRAP FOR THE EXCESS PROCESSING FLUID. THE SHEET WHOSE TRAILING END IS FOLDED BACK TO FORM THE TRAP SHOULD BE MADE OF MATERIAL HAVING SUFFICIENT RIGIDITY AND/OR RESILIENCE THAT IT RESISTS FOLDING SO THAT THE FREE END OF THE FOLDED-BACK FLAP NORMALLY REMAINS SPACED FROM THE SHEET PROPER TO FROM AN OPEN MOUTH FOR RECEIVING EXCESS PROCESSING FLUID. THE LONGITUDINAL EDGES OF THE FOLDED-BACK TRAP ARE SEALED TOGETHER IN SUCH A WAY AS TO PREVENT THE FLOW OF PROCESSING FLUID FROM THE EDGES BUT TO ALLOW THE ESCAPE OF AIR THEREFROM. AT LEAST ONE PROTUBERANCE IS EMBOSSED IN EACH OF THE SEALED EDGES TO EFFECT A SIGNIFICANT SEPARATION OF THE PRESSURE APPLYING MEMBERS AS THE TRAP PASSES THEREBETWEEN WHEREBY THE FOLDED-BACKED FLAP WILL NOT BE COMPRESSED SUFFICIENTLY TO CAUSE A BACK FLOW OF ANY FLUID WHICH HAS ENTERED THE TRAP.

摘要： A film pack for use in an in-camera processing system comprising a container in which a plurality of individual film units, each including a light-sensitive film and an image-receiving sheet coupled by means including a leader, a pull tab connected to said leader, are arranged in stacked relation so that after the film of each unit is exposed it can be moved into superposed relation with its corresponding image-receiving sheet for processing when the pull tab extending from the container, and camera it is associated with, is pulled. The pull tabs of all of the film units are folded back upon themselves and interleaved with the film units so as to be confined wholly within the container until they are pulled successively therefrom by pulling on the pull tab of the preceding film unit. The pull tab on the first film unit is adhered to a safety cover sheet which is wrapped around the stack of film units to protect them against being fogged during handling of a pack outside of the camera, and is withdrawn from the pack and the camera after the pack is placed in the camera to ready the first film unit for exposure. To permit ready assemblage of the film units, the pull tabs are provided with patches or stripes of a cohesive adhesive material so arranged that the pull tabs become adhesively connected together, and the pull tab of the first film unit becomes adhesively connected to the safety cover sheet, with bonds having the necessary shear and peel strengths by the mere application of pressure to the stack of film units after the pull tabs have been folded back into interleaved relation with the film units.
