US Patent 7748558 Bear-proof latch for a refuse container

A latch plate slides along a slide plate attached to the body of a refuse container. The latch plate engages a pin on the hinged lid of the container to lock it closed. The plates are spring-biased to keep the container locked. The plates must be moved against the spring to open the lid. The lid can be opened by actuating at least two trigger mechanisms. Rods depressed by the tongs of a garbage truck during pick-up pull cables that overcome the springs disengaging each latch plate from the pins unlocking the lid of the container. Requiring simultaneous actuation of at least two trigger mechanisms makes the latch bear resistant.
