ABSTRACT:
Packaging of the type comprising an outer rectangular box (100) of rigid cardboard or the like, and a flexible inflatable structure (200, 300) situated inside the box and comprising, overlying each of the inside faces of the box, an inflatable cushion for coming into close contact with the article to be packaged. The box includes a bottom closure (120) and a top closure (130) each having self-locking flaps. The inflatable structure comprises two unit assemblies (200, 300) each comprising a central cushion (220, 330) overlying a respective one of the closures (120, 130) of the box, and two side cushions (211, 213; 312, 314) overlying respective side walls (111, 113; 112, 114) of the box, with each assembly further including means (270-274; 370-374; 500) for simultaneously inflating its three cushions, with at least one of the assemblies being inflatable from outside the box. The bottom and top closures of the box are held in the locked position by the pressure exerted thereon by the respective central cushions of the two assemblies (200, 300) of the inflatable structure, once inflated.
