Abstract: An impact resistant container system particularly useful for products such as stacked, thin sheets of photographic-film or printing plates and other articles that must be kept distortion free. The system has an inner container wherein the product is sandwiched between upper and lower protection sheets that extend beyond the corner margins of the product and the product is restrained from movement within the sandwich. The sandwich is snugly positioned within an outer container so that the article is spaced apart on all sides from the vertical walls of the outer container to provide impact protection crush zones.

Abstract: The seating spring assembly includes a series of elongate sinuous spring wires with each of the wires touching each of the adjacent spring wires at frequent intervals along their length. Frangible welds, in the form of spot welding, are provided at spaced apart touching locations along the lengths of the wires to temporarily secure the adjacent spring wires together. A sleevelike plastic coating surrounds the wires and the frangible welds are broken when the seat is occupied by a person so that the plastic coating then constitutes the sole element holding the spring wires together and the full flexibility and comfort of the seating spring assembly is retained.
