Patent number: 8330120Abstract: Even in a case where a spark is generated in an electron beam irradiation device 28, all the vessels 2 being conveyed are sterilized by the irradiation with the electron beam. The electron beam is emitted by heating filaments 42 arranged in a vacuum chamber 40 and the vessels 2 are irradiated with the electron beam taken out into the atmosphere through a window foil 48 of an irradiation window 46 formed to an irradiation section 44. The vessels 2 are conveyed in a state of being held by vessel holding portions 36A and 36B of a vessel conveying device 24 and pass in front of the irradiation window 46.

Patent number: 8172290Abstract: A gripper has a pair of supports 22A, 22B positioned on opposite sides of a bottle made of resin, and abutments 24A, 24B disposed respectively on the supports 22A, 22B for holding the bottle 4 made of resin, each of the abutments 24A, 24B have two thin plates 26A, 28A, 26B, 28B which are vertically spaced from each other. The abutments 24A, 24B hold the bottle 4 by gripping a neck 4a of the bottle 4 on its opposite sides. While holding the bottle 4, the supports 22A, 22B are held out of contact with an outer surface of the bottle 4, allowing the electron beam to travel around the neck 4a to sterilize the entire surface of the bottle 4.Type: GrantFiled: January 18, 2008Date of Patent: May 8, 2012Assignee: Shibuya Kogyo Co., Ltd.Inventors: Yukinobu Nishino, Tokuo Nishi, Yukihiro Yamamoto

Patent number: 8117803Abstract: Atmosphere in a sterilization box 18 is prevented from entering into a filler chamber 44 side, and also, atmosphere on the filler side is prevented from flowing on the sterilization box 18 side. An intermediate chamber 40 is disposed between the sterilization box 18 for performing sterilization by electron beam irradiation to a vessel 2 and the chamber 44 in which a filler 42 is disposed for filling the sterilized vessel 2 with inner content. A pressure in the intermediate chamber 40 is controlled, by a pressure control device, so as to be higher than a pressure in the sterilization box 18 and higher than a pressure in the chamber 44 provided with the filler 42. Since the pressure in the intermediate chamber 40 is highest, atmosphere in the upstream-side sterilization box 18 is prevented from flowing in the filler 42 side and atmosphere in the chamber 44 for the filler 42 is also prevented from flowing in the sterilization box 18 side.Type: GrantFiled: December 26, 2007Date of Patent: February 21, 2012Assignee: Shibuya Kogyo Co., Ltd.Inventors: Yukinobu Nishino, Tokuo Nishi, Yukihiro Yamamoto
