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.

First claim

The invention claimed is:

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.

2. 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.

3. 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.
