## 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 air supply section chamber disposed on an upstream side of the sterilizing section chamber; and
an exhaust blower in the sterilizing section for exhausting out of the sterilizing section and maintaining a pressure inside the sterilizing section lower than the atmospheric pressure,
wherein the exhaust blower exhausts an air-flow from the air supply section chamber disposed on the upstream side of the sterilizing section chamber and an air-flow from the rinsing section chamber.

### Claim 2 (depends on 1)

The drink filling system according to claim 1, further comprising the exhaust blower in the sterilizing section for maintaining a pressure inside the sterilizing section in a range of −20 Pa to 0 Pa.

### Claim 3 (depends on 1)

The drink filling system according to claim 1, wherein
the air supply section chamber, which has an interior is between the molding section chamber and the sterilizing section chamber;
an atmosphere shut-off chamber that shuts off an atmosphere is between the sterilizing section chamber and the rinsing section chamber; and
the exhaust blower in the sterilizing section exhausts an air flowed from the air supply section chamber and the atmosphere shut-off chamber.
