PURPOSE: A container sealing apparatus is provided to prevent the generation of pin holes by pressing the whole opening part at a constant pressure to thermally weld. CONSTITUTION: A container sealing apparatus comprises a retractile member, an upper die(130), a lower die(140), and a heater. The retractile member is positioned corresponding to an opening part of a container and extends to and retracts from the opening part. The upper die is fixed on the end of the retractile member. The lower die is mounted on the upper die to be tilted and presses the opening part of the container to thermally weld. The heater is mounted on the lower die to generate heat. |
