Abstract: A multi-sheet separator for use in dividing a foldable box comprises at least first and second separator sheets adapted to be shifted between folded and unfolded positions wherein each of the first and second separator sheets includes first and second strip groups that are hingedly interconnected by first and second flap groups. Each of the first and second strip groups include a plurality of longitudinally extending and laterally spaced strip members which are interconnected by respective laterally extending strips. The first and second separator sheets are arranged such that the respective strip and flap groups are positioned in a substantially common plane when the separator sheet is in its folded position and the first and second strip groups are positioned in substantially parallel planes which are spaced a distance defined by the flap groups when the separator sheet is in its unfolded position.
