## Abstract

A drink filling system including: a bottle molding section; a sterilizing section that sterilizes a molded bottle; a rinsing section that rinses the bottle; a filling section that fills and seals the bottle; and a conveying unit that conveys the bottle from the molding section to the filling section. A chamber covers a portion extending from the sterilizing section to the filling section, an atmosphere shut-off chamber is between a sterilizing section chamber and a rinsing section chamber, an exhaust unit for exhausting the atmosphere shut-off chamber and/or the sterilizing section chamber, a clean air supply unit for flowing a clean air from a filling section chamber into the atmosphere shut-off chamber through the rinsing section chamber or for further flowing the air into the sterilizing section chamber, and the air-flow flowing therein is exhausted by the exhaust unit.

## Claims

### Claim 1

A drink filling system comprising:
a molding section that molds a bottle from a heated preform by a blow-molding treatment;
a sterilizing section that contacts a sterilizer to the molded bottle:
a rinsing section that rinses the bottle discharged from the sterilizing section;
a filling section that fills the bottle rinsed in the rinsing section with a drink and then seals the bottle filled up with the drink;
a bottle conveying path that continuously conveys the bottle from the molding section to the filling section through the sterilizing section and the rinsing section,
a chamber that covers a portion extending from the molding section to the filling section;
an atmosphere shut-off chamber that shuts off an atmosphere between the sterilizing section chamber and the rinsing section chamber;
an exhaust blower that exhausts out at least one of the atmosphere shut-off chamber and the sterilizing section chamber;
an exhaust duct that is connected to the exhaust blower;
a conveyor for discharging the bottle near a side of an exhaust port of the filling section chamber, the conveyor for discharging the bottle extending from a discharge wheel toward the exhaust port of the filling section chamber;
a sterilizing tank for sterilization of the conveyor by dipping; and
a duct connected to the exhaust duct for exhausting a sterilizer evaporated from the sterilizing tank by the exhaust blower.
