PROBLEM TO BE SOLVED: To reduce the total cost by a method wherein a formed plastic over- cap to seal and cover a liquid-stopping sealing cap, is fitted on the outer rim protruding part of a charging/discharging port. SOLUTION: For a charging/discharging port 6 having a liquid-stopping sealing cap 32, which is provided on a composite container for liquid wherein a plastic internal bag 20 is housed in an external box made of bond paper, a formed plastic over cap 30 is fitted on the outer rim protruding part 62 of the charging/discharging port 6 so that the liquid-stopping sealing cap 32 can be sealed and covered. The formed plastic over cap 30 is fixed by fitting on the outer rim protruding part 62 of the charging/discharging port 6. The bag- shaped over cap is heat-welded to the outer rim protruding part 62 of the charging/discharging port 6 so that the liquid-stopping sealing cap 32 may be sealed and covered. By this method, a filling work for a content can be highly efficiently performed, and a troublesome state wherein an exclusive measuring device to confirm a sterilization effect is required, can be eliminated. |
