内部の薬液等が見えなくなってしまう。However, in the conventional steam sterilizer, the temperature in the sterilization container is set to the temperature required for heat sterilization (eg, 12
(About 0 to 130 ° C.), the temperature of the storage container housed therein tends to be uneven, and a large difference occurs between the temperature of the storage container and the ambient temperature. When the storage container is made of polyethylene, not only does the storage container become cloudy based on this temperature unevenness and a large temperature difference, and the appearance becomes poor,
The chemical solution inside will be invisible.
本発明の液体を収納したポリエチレン製容器の加熱方
法は、上述の様な不都合を解消するものである。The method for heating a polyethylene container containing a liquid according to the present invention eliminates the above-mentioned disadvantages.

る。(Means for Solving the Problem) In the method for heating a polyethylene container containing a liquid according to the present invention, a polyethylene container containing a liquid such as a chemical solution is stored in a sterile container, and the sterile container is sealed. As shown by the solid line a in the drawing, the temperature in the sterilization container is raised to a temperature necessary for heat sterilization while repeating the process of slightly increasing the temperature in the sterilization container and then leaving the container to stand for a predetermined time.

容器内の薬液等の液体を収納したポリエチレン製容器の
温度は、図面に破線ｂで示す様に、徐々に上昇する。(Operation) As described above, when the temperature in the sterilization container is increased stepwise by repeating the operation of heating and leaving a plurality of times, the temperature of the polyethylene container storing the liquid such as a chemical solution in the sterilization container is increased. Gradually rises as shown by the broken line b in the drawing.
この為、液体を収納したポリエチレン製容器に温度む

度との間に大きな差が生じて白濁するのを防止できる。In addition, after maintaining the temperature in the sterilization container for a predetermined time at a temperature necessary for heat sterilization, when lowering the temperature in the sterilization container, as shown by a solid line a in the drawing as necessary, for example, The temperature is decreased stepwise while repeating the operation of stopping the supply of cooling air for a short time, causing uneven temperature in the polyethylene container or a large difference between the temperature of the polyethylene container and the ambient temperature. Clouding can be prevented.
