  • Patent number: 10906793
    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.
