  • Patent number: 6913164
    Abstract: A versatile drawer organizer structure for segregating a plurality of items. The structure includes a front and back wall and a blank of sheet material wherein a filler is sandwiched between a lower liner and an upper liner. The blank is folded transversely along break lines to define end walls, dividing walls and floor panels between successive walls. The blank is then adjusted in accordion fashion to the inside width of a drawer and held in that shape by attaching a front and a back wall. Thus the structure can be easily sized to precisely fit the inside width of a large number of different drawers and many other enclosed spaces.
