Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a waste liquid container for photographic processing liquid, and more particularly to a waste liquid container that can easily store the waste liquid in a waste liquid chamber even when there is no pressure on the processing waste liquid. [Background of the Invention] In general, photographic processing of silver halide photographic materials includes development, fixing, washing, etc. in the case of black and white photographic materials.
In the case of color photosensitive materials, steps such as color development, bleach-fixing (or bleaching and fixing), washing, and stabilization are performed using a processing solution that has one or more of these functions. In photographic processing in which a large amount of light-sensitive material is processed, the components consumed during processing are replenished, and on the other hand, components that increase in the processing solution due to processing (for example, bromide ions in the developer, bromide ions in the fixer) are replenished. A method is used to maintain the performance of the processing solution at a constant level by removing substances (such as silver complex salts) and keeping the processing solution components constant.A replenisher is added to the processing solution to replenish the above. In the photographic processing described above, a part of the processing solution is discarded in order to remove the increasing components. In recent years, the system has been changing to a system in which the amount of replenishment fluid, including the washing water used as a replenishment fluid for washing, has been drastically reduced due to pollution and economic reasons. It is led through a kana drainage pipe, diluted with waste water from flushing water, and disposed of in a sewer, etc. On the other hand, due to constraints from water resources, rising water supply and drainage costs, the ease of installing automatic processors, and the work environment around automatic processors, in recent years stabilization treatments have been used to replace washing with water, and Photographic processing using automatic developing machines (waterless automatic developing machines) that do not require piping for water supply and drainage is becoming popular. In such a process, it is said to be desirable to omit cooling water for keeping the temperature of the process liquid constant. In such photographic processing, the waste liquid from the automatic developing machine is only the waste liquid of the processing liquid using the replenisher, and the amount of waste liquid is significantly smaller than that in the case where water washing is performed. Therefore, the piping outside the machine for supplying and draining liquid can be omitted, which is considered to be a disadvantage of conventional automatic processors. The disadvantages such as the large amount of piping work required during installation and the energy costs required for hot water supply are all eliminated, and the extremely large advantage is that it can be made compact and simple until it can be used as an office machine. Demonstrated. However, although conventional automatic processing machines were certainly compact, they required at least a photographic processing solution container to supply the processing solution and a waste solution container to store the waste solution. There was a minimum of space for six in total, two each for development, bleach-fixing, and water-washing alternative stabilization processing. Recently, there have been attempts to use so-called flexible containers for waste liquid containers in consideration of their ease of handling. Such a container is made by sealing a laminate film or the like, and remains flat until the waste liquid is collected. When collecting waste liquid, it is necessary to support the opening 5. That is, when the container 1 is made of a flexible material, an auxiliary plate 8 or the like as shown in FIG. 5 is used to stabilize the position of the opening 5 of the container 1 when used as a waste liquid collection container.
The auxiliary plate 8 is made of a hard material such as a synthetic resin material or metal, and has an upper surface portion 9 and a side surface portion 1.
0 and a bottom part 11. A mouth fixing part 12 for fixing the opening 5 of the container 1 is formed on the upper surface part 9, and the opening 5 is hooked and fixed to the mouth fixing part 12, so that the opening 5 is fixed directly below the waste liquid outlet. To be able to stay in a fixed position. By the way, Japanese Patent Publication Nos. 55-55942 and 56-131155
No. 58-52065 and Japanese Utility Model Application No. 56-94754 disclose a technique in which one waste liquid container is divided into two by a diaphragm. According to these techniques, the processing liquid supply container and the waste liquid container can be provided in one container, which certainly results in a reduction in space. [Problems to be Solved by the Invention] However, when trying to store waste liquid in a flexible waste liquid container as shown in FIG. It has been found that if there is not enough pressure to spread the waste liquid and allow it to enter the room, the storage of waste liquid will stop or the liquid will overflow. For this reason, it is conceivable to provide a pump in the waste liquid line as a means for applying pressure, but this has the drawback of increasing costs. [Object of the Invention] Therefore, an object of the present invention is to provide a waste liquid container that can easily store waste liquid without applying any pressure to the waste liquid. [Means for Solving the Problems] As a result of intensive studies, the present inventor has developed a waste liquid container for storing waste liquid of photographic processing liquid for photographic light-sensitive materials, the waste liquid container being flexible and having liquid absorption. It has been discovered that the technical problems can be achieved by a waste liquid container for photographic processing liquid, which is characterized by containing an expandable substance, and has led to the present invention. In a preferred embodiment of the present invention, the waste liquid container has at least two compartments separated by a diaphragm, one of the compartments is a supply chamber for photographic processing solution, and the other is a waste liquid chamber, and the waste liquid container has at least two compartments separated by a diaphragm. A liquid-absorbing and expanding substance is provided in the chamber. [Specific Configuration of the Invention] Hereinafter, an example of a specific configuration of the present invention will be described based on the accompanying drawings. FIGS. 1 and 2 are cross-sectional views showing an embodiment of the present invention, and FIG. 1 shows a photographic processing solution stored in a supply chamber before the liquid-absorbing and expanding material absorbs waste liquid.

At this time, the rectangular flexible film F2 has an opening 4, and the opening 4 is sealed S while penetrating the through hole of the rectangular flexible film F1. As a result of the above, the waste liquid chamber 3 in which the liquid-absorbing and expanding substance 6 is provided is formed. The flexible film F3 forming the supply chamber 2 is then sealed S. Note that it is preferable that the openings 4 and 5 be threaded so that a lid can be attached thereto. Reference numeral 6 denotes a liquid-absorbing and expanding substance, which is housed in the waste liquid chamber 3 so that it expands by absorbing liquid and can press and move the diaphragm 1A. The storage amount of the liquid-absorbing and expanding substance 6 may be arbitrarily determined depending on the purpose.

From this state, the processing liquid is supplied through the opening 4 to an automatic developing machine (not shown). The waste liquid from the automatic developing machine is sent into the waste liquid chamber 3 through the opening 5. At this time, the waste liquid to which no pressure is artificially applied comes into contact with the liquid-absorbing and expanding substance 6 in the waste liquid chamber 3 and is absorbed. As this absorption continues, the liquid-absorbing and expanding material 6 expands, and at the same time the liquid in the supply chamber 2 decreases, gradually approaching the state shown in FIG. 2.
