Abstract
A step of letting a preform (1) made of resin adsorb a sterilizer, a step of sterilizing the preform (1) by heating the preform (1) having adsorbed the sterilizer to a temperature suitable for a blow-molding treatment to activate the sterilizer adsorbed by the preform (1) and a step of shaping the preform (1) into a bottle (2) by blowing aseptic air into the preform (1) in a mold (4) are performed sequentially. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.
Claims19
A method of sterilizing a bottle, comprising the steps of:
- letting a preform made of resin adsorb a sterilizer;
- sterilizing the preform by heating the preform having adsorbed the sterilizer to a temperature suitable for a blow-molding treatment to activate the sterilizer adsorbed by the preform;
- and
- shaping the preform into a bottle by blowing air into the preform in a mold,
- wherein the above-mentioned steps are performed sequentially.
An apparatus for sterilizing a bottle, comprising:
- a transfer unit that transfers a preform having adsorbed a sterilizer or a bottle from a supplying stage of the preform to a molding stage of the bottle;
- a heating furnace that heats the preform to a temperature for a blow-molding treatment to activate the sterilizer adsorbed by the preform, thereby sterilizing the preform;
- and
- a mold that blow-molds the preform into the bottle by air,
- wherein the heating furnace and the mold are arranged in series from an upstream side toward a downstream side of the transfer unit.
