Each retention flap is foldable inwardly and has a free end substantially parallel to said opposing two parallel vertical walls in the first pair. The free end is indented to form a first cutout. Form one of the opposing vertical walls in a second pair continuously extends a ramp flap. The ramp flap is foldable inwardly and has a pair of latch lugs.
