## 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 through to the filling section. A chamber covers a portion extending from the sterilizing section to the filling section, and an atmosphere shut-off chamber is provided between a sterilizing section chamber and a rinsing section chamber. An exhaust unit is provided for the atmosphere shut-off chamber and/or the sterilizing section chamber, a clean air supply unit is provided for a filling section chamber so that a clean air flows from the filling section chamber into the atmosphere shut-off chamber through the rinsing section chamber or further flows into the sterilizing section chamber, and the air-flow flowing therein is exhausted by an 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, which has an interior, that is between the molding section chamber and the sterilizing section chamber;
a first clean air supply unit that flows clean air from the interior of the air supply section chamber into the molding section chamber and the sterilizing section chamber;
an atmosphere shut-off chamber that shuts off an atmosphere between the sterilizing section chamber and the rinsing section chamber;
a second clean air supply unit that flows clean air from the filling section chamber into the atmosphere shut-off chamber through the rinsing section chamber or further into the sterilizing section chamber; and
an exhaust blower for at least one of the atmosphere shut-off chamber and the sterilizing section chamber, the exhaust blower exhausts the flowing air that flows from the filling section chamber into the atmosphere shut-off chamber through the rinsing section chamber or further into the sterilizing section chamber and from the interior of the air supply section chamber into the sterilizing section chamber.

### Claim 2 (depends on 1)

The drink filling system according to claim 1, further comprising a heater that supplies a heated clean air from the first clean air supply unit into the air supply chamber.

### Claim 3 (depends on 1)

The drink filling system according to claim 1, wherein a portion of the sterilizing section chamber at which the bottle travels while being applied with a sterilizer is covered with a tunnel member.

### Claim 4 (depends on 2)

The drink filling system according to claim 2, wherein a portion of the sterilizing section chamber at which the bottle travels while being applied with a sterilizer is covered with a tunnel member.
