PROBLEM TO BE SOLVED: To measure the amount of electrons reaching the inside of a resin-made container 2 for confirming the execution of proper sterilization, in an apparatus for performing sterilization by irradiating the resin-made container 2 with an electron beam.SOLUTION: The apparatus executes the sterilization by irradiating a resin-made container 2 held and conveyed by a gripper 28 of a container conveying device 20 with an electron beam from an electron beam irradiator 16. When performing the irradiation with the electron beam, an electron capturing member (earth rod) 60 is inserted from a mouth opening 2b of the resin-made container 2 into the inside, and a current flowing from the electron capturing member 60 to the earth side is measured by a current measure (ammeter) 76. Accordingly, the amount of electrons reaching the inside of the resin-made container 2 is measured.COPYRIGHT: (C)2012,JPO&INPIT【課題】樹脂製容器2に電子線を照射して殺菌する装置において、適正な殺菌が行われたことを確認するために、樹脂製容器2の内部に到達した電子量を測定する。【解決手段】容器搬送装置20のグリッパ28に保持されて搬送される樹脂製容器2に電子線照射手段16から電子線を照射して殺菌を行う装置であり、電子線を照射する際に、樹脂製容器2の口部2bから内部に電子捕捉部材(アースロッド)60を挿入し、この電子捕捉部材60からアース側に流れる電流を電流測定手段(電流計)76で測定することにより、樹脂製容器2の内部側に到達した電子の量を測定する。【選択図】図2
