Description of the Related Art As a light-sensitive material processing apparatus for processing an exposed light-sensitive material, for example, there is a light-sensitive material processing apparatus which continuously conveys the light-sensitive material to each processing tank for color development, bleaching, fixing or bleach-fixing, stabilization, and the like. In order to prevent deterioration of the finish quality of the photosensitive material due to deterioration of the processing liquid in the processing of the photosensitive material or consumption of the processing agent component, for example, a new processing liquid is stored in the processing tank in which these processing liquids are stored. The processing liquid container described above is connected, and the processing liquid is supplied from the processing liquid container to the processing tank by driving the pump. This processing liquid is supplied by adding water to several types of liquid (powder) called a kit consisting of a concentrated liquid or a powder to dissolve it into a use liquid state, or a process liquid in a use liquid state is treated liquid. It is transferred to the container. In recent years, a method has also been proposed in which a liquid in a used liquid state is contained in a processing liquid container and the entire processing liquid container is replaced.

In addition, when using the low replenishment process, which is a recent trend, or the method of processing paper using the overflow liquid from the negative film, the amount of liquid brought in from the previous tank increases and the pH of the processing liquid for color paper is maintained. Therefore, a large amount of pH buffer such as acetic acid must be used, and there are problems such as unpleasant sensation due to leakage of odor from the treatment liquid container and poor health.

Further, the container used in the kit and the like is formed of a resin bottle such as polyethylene, which causes a problem that the container is bulky at the time of disposal and the cost for disposal is high.
