本発明は、非炭酸飲料その他の缶詰製品を充填シタ未封
の薄肉のアルミ等の金属缶又はプラスチック缶等の開口
容器に、液化窒素等の液化不活性ガスを注入供給する装
置に関する。Detailed Description of the Invention The present invention is a method of injecting liquefied inert gas such as liquefied nitrogen into an open container such as an unsealed thin-walled metal can such as aluminum or plastic can filled with non-carbonated beverages or other canned products. It relates to a feeding device.
従来、非炭酸飲料その他の缶詰製品を、薄肉のアルミ等

ため、密封後の容器内の圧力を高め、かつ、内容物の酸
化を防止することを目的として、液体窒素等の液化不活
性ガスを、密封直前に入れる方法がとられてきた。Conventionally, when filling non-carbonated beverages and other canned products into thin-walled metal cans such as aluminum or plastic cans, etc., 1). In order to increase the pressure inside the container and prevent the contents from oxidizing, a method has been adopted in which a liquefied inert gas such as liquid nitrogen is introduced immediately before sealing.
そして、液化不活性ガスを供給する方法としては、主と
して、コンベア等で送られてくる未封の容器を検知して
、その中に、液化ガスを間欠的に滴下する方法が用いら
れて来た。The main method of supplying liquefied inert gas has been to detect unsealed containers sent by a conveyor or the like and intermittently drip liquefied gas into them. .
しかし、このような方法では、わずかの時間のずれ、液
滴の大きさのバラツキ、液滴の数のバラツキ等によって
、供給される液化不活性ガスの量かバラツキ、密封後の
容器の圧力に大きな差が生じていた。However, with this method, slight differences in time, variations in the size of droplets, variations in the number of droplets, etc. can cause variations in the amount of liquefied inert gas supplied and the pressure in the container after sealing. There was a big difference.
このような問題を解決するため、本発明者らは、鋭意研

）、密封容器内のガス圧のバラツキを、格段に小さくす
ることに、初めて成功した。In order to solve these problems, the inventors of the present invention have conducted extensive research and succeeded in turning the liquefied inert gas into a trickle by exuding it through an r-permeable receiver. Developed a device for continuously flowing liquefied inert gas into a container to be supplied (Patent application No. 57-24879).
), succeeded for the first time in significantly reducing the variation in gas pressure inside a sealed container.
しかしながら、この装置について、更に詳細に調べてみ
ると、容器内に残留する液化不活性ガスの賦の比率が、
予想されるほどの１には達していないことが判った。However, when we examine this device in more detail, we find that the proportion of liquefied inert gas remaining in the container is
It was found that it did not reach the expected value of 1.
本発明者らは、このような問題に着目して、種種調査し
たところ、その原因が、開口容器と流下する液化不活性
ガスとの間にかなりの大きさの水下方向の速度差がある
こと、及び、開口容器中の内容物の液面と流下する液化
不活性ガスとの間にもかなりの大きさの東部方向の速度
差があることを見出し、鋭意研究の結果、本発明を完成
するに到った。The inventors focused on this problem and investigated various types, and found that the cause was a considerable difference in velocity in the downward direction between the open container and the flowing liquefied inert gas. They also discovered that there was a considerable speed difference in the eastern direction between the liquid level of the contents in the open container and the flowing liquefied inert gas, and as a result of intensive research, they completed the present invention. I came to the conclusion.
本発明は、移動する開口容器に液化不活性ガスを連続的
に流下供給する装置において、細流となって非直に流下

性ガスを開口容器に供給することを特徴とする液化不活
性ガスの供給方法である。The present invention is an apparatus for continuously supplying liquefied inert gas to a moving open container, in which the liquefied inert gas flowing non-directly in the form of a trickle is applied to an extent that the inner wall is not wetted by the liquefied inert gas. A method for supplying liquefied inert gas, which is characterized by introducing the liquefied inert gas into a heated curved pipe and supplying the liquefied inert gas to an open container as a horizontally obliquely downward or lateral trickle in the same direction as the moving direction of the open container. It is.
本発明の第一の要点は、非直に落下する液化不活性ガス
の流れを、開口容器の移動方向に曲げて、斜下方に、好
ましくは、はぼ水平になるようにして、液化不活性ガス
の流出速度と開口容器の移動速度との差を小さくするこ
と、好ましくは、液化不活性ガスの非直流下距離等を調
節して、両者の速度をほぼ等しくすることにある。The first point of the present invention is to bend the flow of liquefied inert gas that falls non-directly in the direction of movement of the open container so that it is diagonally downward, preferably almost horizontally, and The purpose is to reduce the difference between the outflow speed of the gas and the moving speed of the open container, preferably by adjusting the distance under the non-direct flow of the liquefied inert gas so that the two speeds are approximately equal.
また、このように、非直の流れを横方向に変えることに
より、液化不活性ガスの流れの非直方向の速度を非常に
小さくすることができ２曲管の先端を開口容器の縁にす
れすれの状態にすれば、注入の際の非直方向の速度を殆
ど零とすることができる。In addition, by changing the non-straight flow to the lateral direction in this way, the velocity of the flow of liquefied inert gas in the non-straight direction can be made very small. In this state, the velocity in the non-orthogonal direction during injection can be made almost zero.
本発明の第二の要点は、液化不活性ガスの堆直の流れを
横方向に変えるに当（）、゛内壁が液化不活性ガスで濡
れない程度に加温された曲管を一部いたことにある。The second point of the present invention is that in changing the vertical flow of liquefied inert gas to the lateral direction (), ``a part of the curved pipe is heated to the extent that the inner wall is not wetted by the liquefied inert gas.'' There is a particular thing.
通常、液化不活性ガスのような液体を曲管で誘導する場
合は、液体は、曲管の底を流れて行き、先端で液滴状に
落下するのが普通である。そして、液化不活性ガスが液
滴状に落下するようになれば、供給端にバラツキを生ず
る。Normally, when a liquid such as a liquefied inert gas is guided through a curved pipe, the liquid flows at the bottom of the curved pipe and falls in the form of droplets at the tip. If the liquefied inert gas falls in the form of droplets, variations will occur at the supply end.

曲管内でも、また、注入する場合でも、液化不活性ガス
を細流として維持することに初めて成功した。In order to prevent such droplet-like falling, the present inventors investigated various methods and found that the surface temperature of the inner wall of the curved pipe was lowered by contacting the inner wall with the boiling point of the liquefied inert gas. By dividing the temperature by 1 to a temperature at which the partially vaporized inert gas acts as a lubricant (in the case of liquefied nitrogen gas, set the temperature of the curved pipe to 150°C or higher).
For the first time, we succeeded in maintaining a trickle of liquefied inert gas both inside a curved pipe and when injected.
