an extensible device supporting a multidimensional sorting method for the concurrent sorting and filling of lightweight materials into plastic bags , with interlocking strip fasteners . the device comprising a planar array of at least one ribbed tubular insert , integrated vertically onto a thin plate , and supported above a work surface . each ribbed tubular insert having an exterior surface comprising a plurality of ridges and grooves circumscribing the perimeter of the insert about its elongated axis , and containing a smooth - wall hollow core , with a top opening for loading , and a bottom opening for discharging at a distal end . the tongue and groove of the bag strip fastener securely engages with the insert ridges and grooves , thereby allowing the bags and associated fill material to be vertically suspended above the work surface . the array of inserts and bags are labeled similarly to associate the selected sorting criteria with the applicable bag contents .
