A latch is provided for latching and automatically unlatching a lid from a waste container. The latch mechanism includes a release weight that moves responsive to gravity in a housing from a first position to a second position to cause the latch to disengage from a striker when the latch is rotated to a dump angular orientation. The latch includes a damper that controls movement of the release weight in the housing such that an amount of time for the release weight to move responsive to gravity from the first position to the second position is at least two times an amount of time the release weight would take to move responsive to gravity from the first position to the second position absent the effect of the damper.
