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.
