Abstract: A locking mechanism for a container having a hinged lid comprising a shaft adapted to be secured to a container and journaled for rotation about its axis. A locking bar is removably secured to the shaft and rotatable about the axis with the shaft between a locked position and an unlocked position. A lock lever is secured to the shaft between the locked position and the unlocked position and a roller is mounted on a track over the lock lever for motion into and out of an engagement with a lock lever. The shaft is held from rotation when the roller and the locking bar is in the locking position. The locking bar is free to move into and out of its locked and unlocked position and the roller is moved from its locking position.
