Document Type and Number:
Japanese Patent JP2008500929
Kind Code:
A
Abstract:
A packaging case (C;C′) erected by folding from a one-piece vacuum-formed molded sheet, has rectangular walls (1-4;71-74) that fold, and are clipped closed, about an article (A;S) to be protected from shock. The ends of the case are almost-completely closed by conformal edge-to-edge abutment of end-flanges (8-11;78-81) of serpentine profile that are upstanding from the walls (1-4;71-74). The flange-edges are each molded with ridges (13, 15) and grooves (14, 16) that nest ridge-within-groove with those of the abutting edges, for absorbing shock. The walls (1-4;71-74) are hinged together edge-to-edge, and at their edges rise in steps (23,24,33.34,43,44) to a central plinth (22,32,42). The steps (23,24,33,34,43,44) of adjacent walls abut one another within the erected case for shock absorption, and each wall (1-4;71-74) is strengthened by circular recesses (25-28,35-38,45-49) of reducing diameter with depth, let into its plinth (22,32.42). The circular recesses produce frusto-conical shock-absorbing projections (57,58,60,62,63) on the outside of the case. The case (C′) may accommodate a stack (S) of component-carrying trays (T) protected by end-caps (83).
