To provide a method and a device for charging high-temperature fruit juice or tea or the like without remarkable shrinkage or deformation and sterilizing the container and the plug by the retained heat, even in an inexpensive and low heat-resistant thermoplastic resin container, a PET container having a low crystallinity for instance.

When fruit juice or tea or other drinks are charged at a high temperature for chiefly sterilizing purposes into a low heat-resistant thermoplastic resin container, a PET container having a low crystallinity for instance, The whole body below the neck of the container 1 is contained in another large container 7 and the gap between the containers 1, 7 is filled with cooling water 14. The outside face of the container is continuously cooled and hardened and the container is pressurized from the outside by the water pressure thereof to prevent a remarkable shrinkage or deformation during the charge or after the charge.
