A locking mechanism is disclosed. In one particular embodiment, the locking mechanism may include a hook component configured to be mounted onto an interior surface of a body of a container, a swivel component configured to engage with the hook component when the locking mechanism is locked, and a mount component to which the swivel component is rotatably mounted. The mount component may be configured to be mounted onto an interior surface of a lid of the container. When the container is in an upright position, the locking mechanism may be unlocked by applying an upward force onto the swivel component. When the container is an upside down position, the locking mechanism may unlock automatically.
