Method, apparatus and system of eliminating static charge and filling and sterilizing resin vessel

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.

In a method of sterilizing and filling a resin vessel in which a resin vessel is sterilized by irradiation with an electron beam and a filling nozzle fills the resin vessel with a liquid, the improvement comprises providing a negative charge applying unit for applying a charge on an outer surface of the vessel which is the same polarity as a charge remaining in the interior of a wall section of the resin vessel during the liquid filling step.

A resin vessel sterilizing and filling system, comprising:

• an electron beam irradiator for irradiating a conveyed resin vessel with an electron beam and thereby sterilizing the resin vessel;
• a filling unit comprising a filling nozzle for discharging a liquid into the resin vessel through an upper portion of a mouth portion of the resin vessel which has been irradiated with the electron beam;
• a capping unit for applying a cap on the resin vessel after it is filled with the liquid and a negative charge applying unit for applying a charge onto an outer surface of the resin vessel, wherein the negative charge applying unit applies a charge onto the outer surface of the vessel which is the same polarity as a charge remaining in the interior of a wall section of the resin vessel during the liquid filling of the resin vessel.
