  • the liquids used in these processes are reacted during the operation of the device of chemicals with the material to be developed, so that in the Bad contained chemical exhausted over time.
  • the liquids in the baths depending on the amount of water processing material, replenished from external containers to the already partially Regenerate used liquid again. Because the bath of each liquid only has a limited volume corresponding to the volume supplied a volume of the liquid can be discharged again. This is usually done by Return the liquid to the container itself.
  • connection between chemical containers and processing baths is generally made over hoses loosely suspended in the container, whereby in the inflow to the Processing bath a pump device is provided.
  • a disadvantage of this arrangement is not just a bad mix between the returning Liquid and the unused chemical present in the container, but due to the possibility of oxygen entering the tank at a high level Oxidation rate of the chemical contained in the container.
  • the chemicals used often come with increased Temperatures are used so that the liquids themselves have to be heated.
  • the Heating of the liquids is generally carried out in such a way that the container or in the bath to an optimal temperature for processing heated and kept there.
  • volatile components such as amines or aminal alcohols
  • the escaping gases often they can have a corrosive effect, they can control the electrical system of the development company adversely affect because they have controls such as chips and others in the device attack existing computer hardware.
  • US-A-5,148,208 discloses a container for containing a photographic processing liquid described, in which the liquid in the container from the outside, is heated over the surface of the container. The heat supplied to the container is controlled by a device for temperature measurement, which is also with the Wall of the container is in contact.
  • An object of the present invention is therefore a new container for Recording and distribution of one used in the development of photographic recordings Provide liquid with which the oxidative degradation of the liquid itself can be reduced to a minimum. In addition, the useful life of the used Chemicals are extended.
  • Another task is to provide a container with which contamination of the environment when changing the containers on the developing device is essentially avoided.
  • a container to hold and distribute one liquid used in photographic developments, in which a Liquid line starting from a near the bottom of the container Place one at the top of the container attached to the container Container arranged connector for receiving a connecting device extends.
  • the connector on the bottom of the Container opposite wall attached. Furthermore, the connector further through a separator into a suction area and a return area be divided, the suction area with the liquid line in a continuous Contact is there.
  • the connector and the liquid line are preferably integral with the container educated.
  • the container 1 for holding a liquid has a conventional structure a floor and side walls.
  • the container can be shaped like a canister parallel walls, i.e. a bottom wall, 4 side walls and a lid or can be in the form of a conically tapering bell-shaped container are present.
  • the connector 3 itself represent the top of the container.
  • Others suitable for such containers Shapes are also possible and only from the conditions in the developing device limited.
  • the container is usually made of plastic, especially polyethylene, Polypropylene, PET or composite materials.
  • Liquid line 2 is arranged, via which in the lower region of the container 1st liquid is sucked in and to a in the upper region of the container arranged connector 3 can be performed.
  • the liquid line 2 can with the container 1 may be formed in one piece.
  • the container faces on a wall in a distance from the floor Area an opening in which there is a connector 3 for receiving a Device for removing the liquid from the container is located.
  • the Connector 3 is connected to the container in a sealing connection, for example using conventional fasteners such as a thread or clamps or, in a preferred embodiment, can be made in one piece with the container 1 be trained.
  • the connector 3 has an opening on one of its walls for receiving the liquid line, the opening of the container in such a way is spaced that easy attachment of the liquid line 2 to the connector 3 can be done.
  • the connector 3 contains a separating device 6, the inner volume of the connector 3 in a suction area 4th and a return region 5, wherein a connection to the liquid line 2 is given such that it opens into the suction area 4.
  • a subdivision into a suction area 4 'and a Return area 5 ' is also provided in the device 7 for removing the liquid his.
  • the device 7 is inserted into the connector 3 and through suitable seals, for example O-ring seals, on the connector 3 sealed itself or on the container.
  • the liquid line be designed such that this simultaneously as Handle can serve, whereby handling of the container is facilitated.
  • kits can be supplied by several containers.
  • a kit generally consists of at least two containers containing a developing liquid and a fixing liquid contain.
  • the containers are made using conventional means, such as metal strips, where appropriate with carrying devices provided for receiving and fixed Attachment of containers, etc. summarized.
  • the further containers Activators, secondary developers, bleaching baths, clarifying baths, etc. can contain.
  • Activators, secondary developers, bleaching baths, clarifying baths, etc. can contain.
  • containers for Improvement in the durability of the developed material can be achieved with devices that work without watering, also containers for residual thiosulfate disruptor, rinsing liquids, Stop liquids, stabilizers and liquids for final baths may be provided.
  • the Number of containers assembled into a kit is only due to the spatial Limited conditions in the developing device.
  • the containers 1 Remove from attached to the container 1 itself or to the connector 3 Transport closures the container 1 manually or automatically with a device connected to the removal of the liquid 7.
  • the device 7 for Withdrawal / return of the liquid supplied a separation of inlet and outlet, or such a separation is already provided in connector 3. Doing so the removal device 7 is inserted into the connector 3 such that the suction area 4 'the area of the wall of the connector 3, in which the opening located for the liquid line 2, completely includes and a contact of the return area 5 'is prevented.
  • a separating device for subdivision into a suction area 4 and a return area 5 is provided, only the respective connections with the corresponding supply and discharge lines to and from the processing bath be ensured.
  • connection between the containers and the processing baths is made according to the invention via a device sealingly connected to the connector 3 7 for taking / returning the liquid. This will give further access to Avoided atmospheric oxygen in the chemical container, reducing durability and thus the degree of utilization of the liquids used also increases.
  • a pump device in the lines leading to the processing baths attached, with which the liquid from the container via the supply lines, to be circulated via the processing baths and via the discharge lines can.
