Abstract: A waste dumpster is disclosed that includes a container defined by vertically oriented walls, a fixed floor that closes the bottom of the dumpster and a hinged lid opposite the floor. A moveable floor is above the fixed floor and moves unaided in the walled container depending on the orientation of the dumpster. The moveable floor can be a planar member congruent in size and shape to the fixed floor and is coupled to the fixed floor by a plurality of fixed length restraints that define the movement of the false floor when the container is tilted from a non-upright position towards an inverted position. The movable floor has flexible edges coplanar with the remainder of the movable floor for allowing the movable floor to move more easily when the container is tilted.

Abstract: A dumpster having a moveable false floor which moves from a bottom of the dumpster toward a top opening when the dumpster is tilted to a substantially inverted orientation during collection of trash. The moveable false floor has freedom to move a predetermined length toward the top opening, where upon reaching the predetermined length a restraining device abruptly stops the floor causing the dumpster to shake dislodging adhered trash. Upon being returned to an upright orientation the moveable false floor moves back to the bottom.
