<p>Photographic sheet material is processed using a processing cell (12) through which the sheet material passes. Process liquid is fed from a collapsible storage container (15) to the cell (12) and returned from the cell (12) to the container (15). The returning liquid is caused to enter the container (15) as a jet stream. A cap assembly for the container (15) comprises a body (28) releasably connected to an upwardly facing mouth (16) of the container (15). Inlet and outlet passages (54, 55) pass through the body (28), the inlet passage (54) opening into the container (15) with a cross-sectional area smaller than that of the outlet passage (55) to enable the jet stream to be achieved. Mixing of the returning process liquid in the container in a simple and economical manner is possible without compromising the ability of the container to collapse.</p> |
