  • Patent number: 6102343
    Abstract: A step and lift refuse liner removal system is disclosed, consisting of a conventional refuse container main housing. A conventional refuse liner rests on a support plate, located inside the main housing, above the bottom of the main housing. Air holes in the support plate facilitate air flow throughout the main housing, thus reducing the vacuum between the refuse liner and the side walls of the main housing. A dual fulcrum and curved lever system permits the operator to lift the support plate by pressing down on a foot bar located outside the main housing near the ground. As such, the present invention facilitates the easy and effortless removal of a conventional refuse liner. A set of foot pads are provided to enable the operator to restrict the movement of the main housing relative to the ground.
