Do not twist, twist do not twist, and you will not be able to open the desired bottle of cognac - all "attempts" on the rare drink will be suppressed. Now the place of the usual plug is taken by a lock, but not a simple one, but a code lock, and only the bearer (or custodian) of the top-secret code has access to the life-giving moisture.
The principle of operation of the mechanism is unusually light. A four-digit number - one turn of the plug - the lock is locked. And only the given combination of numbers will unlock it.
