Integral film unit assembly

Abstract

Abstract A FILM ASSEMBLY OF THE SELF-PROCESSING TYPE HAS CERTAIN OF ITS COMPONENT PARTS ADAPTED TO BE SEPARATED BY A SEVERING DEVICE. THE FILM ASSEMBLY COMPRISES A PREREGISTERED INTEGRAL FILM UNIT INCLUDING A PHOTOSENSITIVE ELEMENT AND A SUPERPOSED PROCESS ELEMENT HAVING IMAGE PORTIONS THAT ARE SEPARABLE TO ADMIT A PROCESSING COMPOSITION THEREBETWEEN, A PROCESSING COMPOSITION CONTAINER FOR SUPPLYING THE COMPOSITION TO THE FILM UNIT, AND A PROCESSING COMPOSITION RECEIVER FOR RECEIVING ANY EXCESS COMPOSITION FROM THE FILM UNIT. INTERPOSED BETWEEN AND EXTENDING BEYOND THE PHOTOSENSITIVE AND PROCESS ELEMENTS IS A MASKING MEMBER FOR DEFINING THE IMAGE PORTIONS AND A PREDETERMINED SPACE THEREBETWEEN, FOR CONNECTING THE TWO ELEMENTS WITH EACH OTHER AND THE FILM UNIT WITH THE CONTAINER AND RECEIVER, AND FOR DIRECTING THE PROCESSING COMPOSITION FROM THE CONTAINER TO THE IMAGE PORTIONS AND THE EXCESS COMPOSITION FROM SAID PORTIONS TO THE RECEIVER. THE RECEIVER MAY BE DEFINED BY ONE END OF THE MASKING MEMBER FOLDED BACK UPON ITSELF TO PROVIDE A MAIN PORTION AND A BACK-FOLDED PORTION BETWEEN WHICH THE EXCESS COMPOSITION IS RECEIVED. A PROCESSING-COMPOSITION-ACTIVATED ADHESIVE IS PROVIDED ON APPROPRIATE SURFACES OF THE MASKING MEMBER FOR SEALING THE TWO ELEMENTS TOGETHER AND THE RECEIVER CLOSED AFTER THE PROCESSING COMPOSITION HAS BEEN DIRECTED FROM THE CONTAINER TO THE IMAGE PORTIONS AND THE EXCESS COMPOSITION HAS BEEN DIRECTED TO THE RECEIVER. TO FACILITATE SEPARATION OF THE FILM UNIT FROM THE CONTAINER AND RECEIVER, MEANS ARE PROVIDED FOR GUIDING A SEVERING DEVICE ALONG PREDETERMINED PATHS BETWEEN THE FILM UNIT AND CONTAINER AND BETWEEN THE FILM UNIT AND RECEIVER, THE GUIDING MEANS INCLUDING OPPOSING GUIDE SURFACES DEFINING ELONGATE SLOTS EXTENDING ACROSS THE MASKING MEMBER FOR DEFINING THE PREDETERMINED PATHS AND FOR GUIDING THE SEVERING DEVICE THEREALONG. THE MASKING MEMBER IS ADAPTED TO BE FLEXIBLE ALONG THE PREDETERMINED PATHS IN ORDER TO PERMIT ALTERNATIVE FOLDING OF THE CONTAINER AND RECEIVER OVER ONE OF THE TWO ELEMENTS TO PROVIDE A BACKING FOR THE FINISHED PRINT.
