  • Patent number: 11655133
    Abstract: A cap sterilizer (50) includes an infeed chamber (52), a sterilant atomizing chamber (53), and an air rinse chamber (54). At least the infeed chamber (52) and the air rinse chamber (54) are exhausted. Both an exhaust pressure (E2) in the infeed chamber (52) and an exhaust pressure (E4) in the air rinse chamber are higher than an exhaust pressure (E3) in the sterilant atomizing chamber (53), or the sterilant atomizing chamber (53) is not exhausted.

  • Publication number: 20210179410
    Abstract: An aseptic filling machine and an aseptic filling method are provided with which a petaloid-shape bottle or an unstable bottle which is filled with sterilized content and sealed with a sterilized cap in an aseptic atmosphere is discharged without a delay from an aseptic zone to a non-aseptic zone. Further, even if a petaloid-shape bottle or an unstable bottle falls over on a discharging conveyor when being discharged from an aseptic zone to a non-aseptic zone, a stopping time of the aseptic filling machine can be shortened. A barrier chamber into which air containing a gas of a sterilizer is supplied is provided downstream of a sealing portion that fills content into the bottle and seals the bottle with a cap. Further, a discharge portion chamber that shields a discharge portions provided downstream of the sealing portion that fills content into the bottle and seals the bottle with a cap.
