Claims

[Scope of Claim for Utility Model Registration] 1. A threaded portion A that can be screwed into the threaded portion A′ of a pressurized liquid gas filled can, which progresses in the screwing direction by the screwing operation of the screwed portion A′ and the threaded portion A. A fixed or attached destruction member B that destroys a part of the wall of the enclosure can to form an opening in the enclosure can, a passage configuration C that allows communication between the opening and the atmosphere, and a passageway from the opening to the atmosphere. On the way to the atmosphere via configuration C, communication between the opening and the atmosphere is temporarily blocked at least at the stage when the opening is formed, and after a required period of time, the communication between the opening and the atmosphere is released and the blockage is released. A time-limited can opening device for a pressurized liquid gas-filled can having an erodible member D. 2. A time-limited can opener for pressurized liquid gas-filled cans as set forth in claim 1 of the utility model registration claim, in which the erodible member D is replaceable. 3. The time-limited can opener for pressurized liquid gas-filled cans according to claim 1 or 2, wherein at least a portion of the passage configuration C is transparent.
