Abstract

In a carbonated drink filling method, a preform is continuously transferred and introduced into a heating furnace, heated to a temperature for molding the preform into a container, molded into the container in a molding die after the preform exits the heating furnace, conveyed in an upright position during which a coolant (F) is injected to a bottom of the container to cool the bottom. The container is filled with a carbonated drink (a) through a mouth portion of the container, and the mouth portion is then sealed. The coolant is injected in the cooling to the bottom of the container from a nozzle opening on either or both sides of a conveyance line of the container, and the nozzle opening is directed diagonally upward to the bottom of the container in such a manner that an extension of the nozzle opening intersects with the conveyance line of the container.

First claim

The invention claimed is:

1. A carbonated drink filling method, comprising the steps of:
transferring a preform continuously,
introducing the preform into a heating furnace,
heating the preform to a temperature for molding the preform into a container in the heating furnace,
molding the heated preform into the container in a molding die after the preform exits the heating furnace,
conveying the container in an upright position,
applying a first coolant to a bottom of the container to cool the bottom of the container, the first coolant being applied to the bottom of the container from a nozzle opening on either or both sides of a conveyance line of the container, and a centerline of the nozzle opening is directed diagonally upward to the bottom of the container in such a manner that an extension of the nozzle opening intersects with the conveyance line of the container,
sterilizing the container after applying the first coolant and before the container is filled with a carbonated drink,
applying a second coolant to the bottom of the container after the sterilizing of the container,
filling the container with the carbonated drink through a mouth portion of the container, and
sealing the mouth portion of the container.

2. The carbonated drink filling method according to claim 1 , the method further comprising the steps of:
water rinsing the container after the sterilizing of the container, and
applying the second coolant to the bottom of the container after the water rinsing.

3. A carbonated drink filling system, comprising:
a transfer device that transfers a preform from where the preform is supplied and molded into a container, and that transfers the container from where the container is filled with a carbonated drink and sealed;
a heating furnace that heats the preform to a molding temperature;
a blow molding device that blow-molds the preform into the container;
a first coolant applying nozzle that applies a first coolant to a bottom of the container discharged from a blow molding die in an upright position to cool the bottom of the container, the first coolant applying nozzle being provided on either or both sides of a conveyance line which the container moves along, and the first coolant applying nozzle applying the first coolant from a nozzle opening, such that a centerline of the nozzle opening is directed diagonally upward to the bottom of the container in such a manner that an extension of the nozzle opening intersects with the conveyance line of the container;
a sterilization device which performs a sterilization process on the container, is provided downstream of the first coolant applying nozzle
a second coolant applying nozzle, which applies a second coolant to the bottom of the container after the sterilization process on the container, is provided downstream of the sterilization device,
a filler that fills the container with the carbonated drink through a mouth portion of the container; and
a capper that seals the mouth portion of the container,
wherein the heating furnace, the blow molding device, the first coolant applying nozzle, the sterilization device, the second coolant applying nozzle, the filler and the capper are arranged in this order from an upstream side to a downstream side, with the first coolant applying nozzle and the second coolant applying nozzle being along the transfer device.

4. The carbonated drink filling system according to claim 3 , wherein a water rinsing device is provided downstream of the sterilization device, and the second coolant applying nozzle is provided between the water rinsing device and the filler.
