US Patent 7731112 Underside particle flap for shredder

Disclosed herein is a shredder having a closure located adjacent an output opening of a shredder housing that is selectively positioned to prevent shredded materials from being discharged from the output opening. The closure may be connected to the shredder housing, and the container may comprise a removable waste bin. The closure may be actuated via an actuator to a closed position in response to the container and the shredder housing being moved out of an operative position relative to each other, such as when the waste bin is being emptied. The closure may assist in reducing or eliminating waste from being distributed in or around the shredder.
