A refuse compactor having a packing blade hinged under the cover of a container and movable through an automatic refuse packing cycle involving initial downward extension of the blade through a packing stroke by atmospheric pressure and gravity, to effectively compact refuse within the container, and final upward return of the blade by air pressure to a normal retracted position against the underside of the cover each time the cover is locked in closed position. The compactor embodies a safety feature whereby the packing blade is securely latched in the retracted position and positively inactivated against extension through its packing stroke except when the compactor cover is locked in closed position.
