  • Opening device for a garbage can having two hinged lid segments
    Patent number: 6626317
    Abstract: A garbage can has a first lid segment hingedly attached to a first wall and a second lid segment hingedly attached to a second side wall. An actuator raises the lid segment from a closed position to an opened position. The actuator includes vertical rods attached to a foot pedal. Depression of the foot pedal causes the vertical rods to move upwardly and move the lid segments into the opened position. The first and second side walls meet a corner and a third arcuate side wall connects the first and second side wall to give the garbage can a sector shape.
