Abstract

The automatic film developer system uses a two-chambered bag-bottle for dispensing and solution changing. Container 11 has a rigid outer bottle 13 which surrounds collapsible inner bag 15 that holds the developer solution. Bag 15 is connected to bottle 13 at pierceable seal 17. Container 11 is placed in position such that tubes 19 and 21 pierce seals 17 and 23. Tube 19 extends into bag 15 and tube 21 extends into cavity 25 between bottle 13 and bag 15. Tube 21 is connected to a source of water under pressure which is controlled by valve 27. The latter directs the water into cavity 25 and forces developer liquid into delivery tube 29 and out of heated spray nozzle 31 onto the surface of film 33. Water is then directed by valve 27 into tube 29 and nozzle 31 to clean them of developer.
