The objective of the present invention is to provide a container sealing device with which the user clearly perceives an opening sensation upon breaking the seal of an inner plug. This container sealing device is provided with an inner plug (10) and an upper lid (20), and the upper lid (20) can be attached and detached by first screw fitting parts (51) provided between the upper lid (20) and a container (1) or the inner plug (10). The upper lid (20) has a support part that, upon cap removal, uses second screw fitting parts (52) to catch a detachment part (12) provided to the inner plug (10) and detaches the detachment part (12) from the inner plug (10). The forward screwing direction of the second screw fitting part (52) is the opposite to the forward screwing direction of the first screw fitting part (51). First stoppers (16t, 20u) that define the assembly space between the upper lid (20) and the detachment part (12) of the inner plug (10) are provided therebetween. |
