Packaging

A packaging case of molded-sheet construction for enclosing one or more articles to protect them against damage and shock during storage and transit, wherein the case has rectangular walls of sheet material molded with recesses for strengthening the walls, the walls are hinged together for erection of the packaging case from a flat condition to an erect condition, each wall has two longitudinal edges each of which abuts a respective one of the two longitudinal edges of another of the walls in the erect condition of the packaging case to form abutting pairs of edges between the walls in the erect condition of the packaging case, and the walls have upstanding end-flanges each of which has an elongate edge that abuts the elongate edge of another of the flanges in the erect condition of the packaging case to form abutting pairs of edges between the flanges in the erect condition of the packaging case, and wherein each abutting edge of each individual pair of abutting edges of the walls and of each individual pair of abutting edges of the flanges has both ridges and grooves running along the edge for ridge-to-groove nesting with the grooves and ridges respectively of the other abutting edge of the respective pair for strengthening the packaging case in its erect condition.

A packaging case for enclosing one or more articles to protect the one or more articles against damage and shock during storage and transit, wherein the case has walls which are of sheet material, the walls have recesses therein for strengthening the walls, and the walls have pairs of abutting edges for edge-to-edge abutment of the two abutting edges of each pair with one another, and each abutting edge of each individual pair of abutting edges has both ridges and grooves for ridge-within-groove nesting with the grooves and ridges respectively of the other abutting edge of the pair when those edges are in mutual abutment, the walls have flanges that abut one another edge-to-edge, and the abutting edges of the flanges are each formed with ridges and grooves to nest with one another ridge-within-groove when in mutual abutment, and wherein the walls are rectangular and are hinged longitudinally to one another for erection of the case from a flat form, and the flanges are upstanding from ends of the walls to be brought into edge-to-edge abutment one with another on erection of the case.
