Method of eliminating static charge from resin vessel, method of sterilizing and filling resin vessel, method of filling and capping resin vessel, apparatus for eliminating static charge from resin vessel, and resin vessel sterilizing and filling system

Abstract

To eliminate charges accumulated inside a wall structure of a resin vessel 2, which is sterilized by an electron beam irradiator 16, an ionizer 134 disposed outside a filler 112 emits to the outer surface of the resin vessel 2 with negative ions having the same polarity as that of charges accumulated in the wall section of the resin vessel 2, while conveying the resin vessel 2 sterilized by the electron beam irradiator 16 to the filler 112, by which liquid fills the resin vessel 2. A filling nozzle 132 is connected to ground, and an ion flowing path is formed through a liquid column La filling the interior of the resin vessel 2 from the filling nozzle 132 .

What is claimed is: 
     
         1 . A method of eliminating static charge from a resin vessel by using an apparatus including a liquid supply unit for supplying a liquid into a resin vessel and a charge applying unit for applying charge to an outer surface of the resin vessel, wherein, by applying charge having a same polarity as that of charge remaining in an interior of a wall section of the resin vessel, while supplying the liquid into the resin vessel, ion carrying charge having a polarity reverse to that of the charge remaining in an interior of the wall section of the resin vessel is attracted to an inner surface of the resin vessel. 
     
     
         2 . The method of eliminating static charge from a resin vessel according to  claim 1 , wherein the charge applying unit is a device for emitting to the outer surface of the resin vessel with ions. 
     
     
         3 . An apparatus for eliminating static charge from a resin vessel comprising a liquid supply unit for supplying a liquid into a resin vessel and a charge applying unit for applying charge to an outer surface of the resin vessel which is filled with the liquid by the liquid supply unit, wherein charge having a same polarity as that of charge remaining in an interior of a wall section of the resin vessel is applied to the outer surface of the resin vessel by the charge applying unit during the supply of the liquid into the resin vessel by the liquid supply unit. 
     
     
         4 . The apparatus for eliminating static charge from a resin vessel according to  claim 3 , wherein the charge applying unit is a device for emitting to the outer surface of the resin vessel with ions.
