  • Patent number: 8393562
    Abstract: A plastic shredder is provided for shredding plastic and depositing it directly into a garbage receptacle. An interior channel extends between a top and a bottom of a housing. An upper roller and a lower roller are positioned in and extend across the interior channel. The upper roller is positioned parallel to the lower roller in spaced relationship forming a gap. Upper teeth extend from an outer surface of the upper roller. Lower teeth extend from an outer surface of the lower roller. The lower teeth mesh with the upper teeth for pulling plastic through the gap where the plastic is shredded. A lip extends outwardly from a middle section of the outer wall of the housing. The lip is positionable to engage an upper edge of a container such that the interior channel empties into the container for collecting the plastic after the plastic is shredded.
