CONTAINER WITH GRAVITY RELEASABLE LOCKING LIDS

A container comprises a body having an opening, a lid for selectively covering the opening, and a lock system for securing the lid. The lock system comprises a pivot pin mounted to the lid, a lock pin mounted on the body adjacent the opening and generally vertically aligned with the pivot pin when the container is upright, a first and second latch members pivotally mounted on the pivot pin and configured to engage the lock pin from first and second sides thereof, and a limiter slidably mounted on the pivot pin between the first and second latch members and configured to engage and control the rotation of the first and second latch members, the limiter weighted such that when the container is upright the limiter is biased by gravity towards the pivot pin when the first and second latch members engage the lock pin and prevent the first and second latch members from disengaging the lock pin. The latch members each comprise a latch body having a recess sized to receive the lock pin, and a bottom surface shaped to pivot the latch member away from the lock pin when the latch body contacts the lock pin as the lid closes.
