1. A container sealing device comprising:
an inner plug having a body part disposed integrally at a mouth part of a container and a separation part joined to the body part via a score and forming an opening by being separated from the body part; and an upper lid engaged with the separation part and screwed to the container or the body part so as to cover the inner plug, wherein a plug-opening mechanism part belonging to the inner plug and the upper lid is provided; and the plug-opening mechanism part has an upper-moving plug-opening mechanism that opens the plug by rotating the upper lid in a direction of loosening the upper lid with respect to the container to thereby separate the separation part from the body part while holding the separation part by a support part provided on an inner side of the upper lid; and a lower-moving plug-opening mechanism that opens plug by rotating the upper lid in a direction of tightening the upper lid with respect to the container to thereby separate the separation part from the body part while holding the separation part by the support part. |
