ELECTRON BEAM STERILIZATION METHOD FOR BOTTLE CAP AND ELECTRON BEAM STERILIZATION DEVICE

Title:

ELECTRON BEAM STERILIZATION METHOD FOR BOTTLE CAP AND ELECTRON BEAM STERILIZATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/166698

Kind Code:

A1

Abstract:

An electron beam sterilization method for a bottle cap has the following steps when a bottle cap (C) is sterilized by sequentially lowering the bottle cap (C) along a sterilization path (15e) in the vertical direction while the bottle cap (C) is oriented such that the cap axis thereof through the center of an opening surface is substantially horizontal, and radiating an electron beam on the bottle cap (C). First, in the sterilization path (15e), atmospheric gas is sucked through a suction hole (25) formed along the vertical direction in a guide wall, thereby drawing the closed surface of the bottle cap (C) toward the guide wall, and an electron beam is radiated on the opening surface of the bottle cap (C). Next, in the sterilization path, the atmospheric gas is sucked through the suction hole formed along the vertical direction in the guide wall, thereby drawing the opening surface of the bottle cap toward the guide wall, and an electron beam is radiated on the closed surface of the bottle cap.
