ABSTRACT:
An unlocking tool for opening a container operates by the action of a lever. The container includes a first half and a second half connected to each other for rotation. The first half includes a latch finger, and the second half has a hole for receiving the latch finger and engaging with it to keep the container closed. The second half also includes a second hole adjacent to the first hole for suspension of said container. The unlocking tool of the invention functions as a lever along which the tool has an effort point, a fulcrum and an acting point. The tool is formed to pass in part through the second hole of the second half and rotate around the fulcrum positioned in the second hole. When the tool is rotated around the fulcrum positioned in the second hole, the acting point of the tool urges the latch finger to release the engagement between the latch finger and the first hole of the second member, thereby opening the container.
