PROBLEM TO BE SOLVED: To provide a container-unsealing device which is applicable to a paper-made container, and satisfactory in the unsealability and re-sealability of the container. SOLUTION: A mounting member 12 surrounding an area to be unsealed is joined onto the upper wall plate 11A of a hermetic container main body 11, and a lead-out tube 13 is engaged with the mounting member 12. The lower part of the lead-out tube 13 forms a pointed end part 13A, and the upper wall plate 11A can be broken with the pointed end 13A. The upper part of the lead- out tube 13 forms a nozzle part 13E, and above the nozzle part 13E a stopper plate 13J is supported with support legs 13H. Onto the lead-out tube 13 an upward/downward movable cap 14 is fitted, and a liquid-contents discharging opening 14c and the stopper plate 13J are tightly engaged with each other accompanying the upward/downward movement of the upward/downward movable cap 14. In such a configuration, a container can be provided without making an opening in its hermetic container main body 11 and improvement in hygiene is made. Also, by the simple operation of the upward/downward movable cap, unsealability and re-sealability can be improved. |
