ABSTRACT:
A device for use with a cap having a rubber plug which is inserted into the mouth of a container and which can be tightened and loosened by the turn of a lever provided thereto. The device comprises a cap cover loosely but undetachably fitted over the cap so as to enclose its lever, and a pin slidably supported by the cap cover for movement into and out of engagement with the cap lever. The pin can be padlocked out of engagement with the cap lever, so that the cap is loosenable by the manual turn of the cap cover only when the padlock is opened to permit the pin to move into engagement with the cap lever.
