Abstract
The invention is a locking device for a garbage dumpster. The invention includes a vertical channel attached to the front wall of a dumpster. A spring loaded vertical post extends through the vertical channel. A locking mechanism is attached to the spring loaded vertical post and rotatably attached to the top of the vertical channel. When a dumpster is on the ground, the weight of the dumpster against the ground engages the lock on top of the dumpster lid. When the dumpster is lifted from ground, the lock is disengaged from the dumpster lid via a spring.
