Abstract

Abstract The waste receptacle cover has an upper portion and a lower portion. The upper portion has a swinging top which, along with the supports for the top, cover the top of the waste receptacle. Depending from the upper portion is a lower portion including a baffle which has walls angled toward the center of the container and generally vertical walls depending from the angled walls. The vertical walls create an opening so that waste dropped through the upper portion when the top is swung open can fall through the opening. The angled walls and the vertical walls together create a baffle that directs combustion products back down onto waste within the container if a fire starts and prevents oxygen from reaching the fire. The bottom of the swinging top may be closed to further restrict the amount of oxygen within the container. The connection between the upper portion and the lower portion includes a guide for camming the cover into place on top of the waste receptacle.
