PROBLEM TO BE SOLVED: To provide a sealing plug which prevents the reduction of cool feeling and flavor as a carbonated beverage due to the degasification of carbon dioxide in drinking water with the lapse of time even if being sealed with a cap attached to a bottle when temporarily opening a commercial household carbonated drinking water container and storing drinking residue, which is used for housing and storing in a household refrigerator and whose detaching operation is easy.SOLUTION: A sealing plug instead of a cap attached to a container performs the sealing of a carbonated drinking water container after opening by pressurization with a compact pressure pump. A piston part (4) is housed in a cylinder part (5) to keep a shortest length shown in [Fig 4] after finishing a pressure operation and can be housed in the door panel pocket of a household refrigerator. Further, the detachment of the sealing plug can be easier than the drinking water container with a smaller force and one operation by making the diameter of a pump head cap (1) larger if necessary when fitting (2) to (1) and being integrated shown in [Fig 4]. |
