Boxes of trilaminar cardboard with corrugated core - are made by folding and joining three components and build into pigeon holed furniture units

摘要

The construction of a cuboid bar module may utilize three components forming the outer skins, the core to the top, bottom and lateral panels, and the core to the rear panel. The primary component comprises a rectangular strip which is sub-divided by fold lines (7) into four square panels (6). One extremity of the strip has a lap flap (15), four square flaps (8) extend from one long edge, and two flaps (12) spaced at panel intervals extended from the opposite long edge. Panels (6) form the top, bottom and lateral outer module faces. Panels (8) fold in to form the inner faces and contain the core strip (16). Panels (12) form the module rear and sandwich core panel (18).
