【発明の詳細な説明】 （産業上の利用分野） この発明は、ポリエチレン容器等の可撓性を有する容
器内に貯溜された液体の加熱滅菌方法に関し、上記容器
内の圧力上昇により、この容器が破裂する事の防止を図
るものである。Description: TECHNICAL FIELD The present invention relates to a method for heat sterilization of a liquid stored in a flexible container such as a polyethylene container. Is to prevent the rupture.
（従来の技術） 医療用として使用される薬品等の液体は、ポリエチレ
ン容器等の可撓性を有する貯溜容器に入れ、この貯溜容
器の口を密閉した状態で、上記貯溜容器ごと、蒸気滅菌
器等により加熱滅菌処理する。(Prior Art) A liquid such as a medicine used for medical use is put in a flexible storage container such as a polyethylene container, and the storage container is sealed with its mouth closed. And heat sterilize.
ところで、この様にして貯溜容器中の液体を加熱滅菌
処理する場合、温度上昇に伴なって貯溜容器内の圧力が
上昇する。貯溜容器内の圧力と滅菌容器内の圧力とがほ
ぼ等しい場合、或は滅菌容器内の圧力の方が少し高い様
な場合には、特に問題を生じる事はないが、貯溜容器内
の圧力が滅菌容器内の圧力よりも高くなった場合には、
上記貯溜容器が膨らみ、更に破裂する危険性がある。By the way, when the liquid in the storage container is subjected to the heat sterilization treatment in this manner, the pressure in the storage container increases with the temperature rise. When the pressure in the storage container is substantially equal to the pressure in the sterilization container, or when the pressure in the sterilization container is slightly higher, there is no particular problem. If it becomes higher than the pressure in the sterilization container,
There is a risk that the reservoir swells and further explodes.
この様な原因による貯溜容器の破裂を防止する為の技

内に貯溜された液体の温度から、このサンプル容器内の
圧力を求め、このサンプル容器内の圧力と滅菌容器内の
圧力とがほぼ等しくなる様に、滅菌容器内の圧力を制御
する技術が記載されている。As a technique for preventing the rupture of the storage container due to such a cause, Japanese Utility Model Publication No. Sho 63-7242 discloses a liquid stored in a sample container having the same configuration as the storage container storing the liquid to be heat-sterilized. A technique is described in which the pressure in the sample container is determined from the temperature of the sample container, and the pressure in the sterilization container is controlled such that the pressure in the sample container is substantially equal to the pressure in the sterilization container.
（発明が解決しようとする課題） ところが、上記公報に記載された従来技術の場合、解
決すべき次の様な問題がある。(Problems to be Solved by the Invention) However, the prior art described in the above publication has the following problems to be solved.
即ち、サンプル容器内に貯溜された液体の温度の測定
が正しく行なわれていれば良いが、サンプル容器中への
温度計の差し込み不良等により、上記温度測定が正しく
行なわれないと、サンプル容器内の圧力を正確に求める
事が出来ず、このサンプル容器と同様構成の貯溜容器内
の圧力と滅菌容器内の圧力との間に差が生じ、貯溜容器
が破裂する可能性が生じる。That is, it is sufficient that the temperature of the liquid stored in the sample container is correctly measured. However, if the temperature measurement is not performed correctly due to a poor insertion of the thermometer into the sample container, etc. Cannot be determined accurately, and a difference occurs between the pressure in the storage container having the same configuration as that of the sample container and the pressure in the sterilization container, which may cause the storage container to burst.
本発明の可撓性を有する容器内に貯溜された液体の加
熱滅菌方法は、上述の様な不都合を解消するものであ
る。The heat sterilization method for a liquid stored in a flexible container according to the present invention eliminates the above-mentioned disadvantages.

１を加熱滅菌する。(Means for Solving the Problems) The heat sterilization method of the liquid stored in the flexible container according to the present invention is similar to the conventional heat sterilization method, as shown in the drawing. The storage container 2 having flexibility is accommodated in the sterilization container 3, and in a state where the sterilization container 3 is sealed, the temperature in the sterilization container 3 is increased by sending steam into the sterilization container 3. The liquid 1 in the container 2 is sterilized by heating.

としている。Further, in the heat sterilization method for the liquid stored in the flexible container according to the present invention, the liquid level sensor 4 for detecting the liquid level in the storage container 2 stored in the sterilization container 3 is provided. In addition, the pressure in the sterilization container 3 is adjusted so as to keep the liquid level detected by the liquid level sensor 4 constant.

を調節する事により行なう。As the liquid level sensor 4, a water level sensor (with or without a float), a photoelectric switch, an ultrasonic sensor, or the like can be used. The pressure in the sterilization container 3 is adjusted by adjusting the amount of steam or compressed air to be sent into the sterilization container 3 by opening and closing the valve 5, as in the prior art described in the above publication.

貯溜容器２が破裂したり、変形したりする事を防止出来
る。(Operation) The method for heat sterilizing liquid stored in a flexible container according to the present invention is configured as described above, but the liquid level in the storage container 2 detected by the liquid level sensor 4 is determined. In order to make the pressure inside the sterilization container 3 constant, the pressure in the storage container 2 and the pressure in the sterilization container 3 are set to be substantially the same.
The storage container 2 can be prevented from being ruptured or deformed.
即ち、貯溜容器２内の圧力が滅菌容器３内の圧力に比

下する傾向となり、反対に、貯溜容器２内の圧力が滅菌
容器３内の圧力に比べて低くなると、上記貯溜容器２が
押し潰されて、液位が上昇する傾向となる。That is, when the pressure in the storage container 2 becomes higher than the pressure in the sterilization container 3, the storage container 2 expands and the liquid level tends to decrease, and conversely, the pressure in the storage container 2 increases. When the pressure becomes lower than the internal pressure, the storage container 2 is crushed and the liquid level tends to rise.
この為、上述の様に、液位センサ４が検出する貯溜容
器２内の液位を一定にすれば、貯溜容器２内の圧力と滅
菌容器３内の圧力とをほぼ同じとして、貯溜容器２が破
裂したり、変形したりする事を防止出来る。Therefore, as described above, if the liquid level in the storage container 2 detected by the liquid level sensor 4 is kept constant, the pressure in the storage container 2 and the pressure in the sterilization container 3 are set to be substantially the same, and the storage container 2 Can be prevented from exploding or deforming.
