Photographic developing tanks are described of improved and simplified construction. In particular, the tank has a cylindrical base, the top of which can be closed off in light-tight fashion by a wide funnel member extending right across it. The funnel member fits into the base by a modified latching bayonet fitting constituted by cooperating formations on the inside of the walls of the base member near their top and on the outside of the funnel member. |
