Patent attributes
A container sealing device includes a plug-opening mechanism part belonging to the inner plug 10 and the upper lid 20; and the plug-opening mechanism part has an upper-moving plug-opening mechanism A that opens the plug by rotating the upper lid 20 in a direction of loosening the upper lid with respect to the container 1 to thereby separate the separation part 12 from the body part 11 while holding the separation part 12 by a support part provided on an inner side of the upper lid 20; and a lower-moving plug-opening mechanism B that opens the plug by rotating the upper lid 20 in a direction of tightening the upper lid 20 with respect to the container 1 to thereby separate the separation part 12 from the body part 11 while holding the separation part 12 by the support part.
