Softening Cushion for Shock Protection

A packaging method and means wherein a plurality of cushions in the form of generally semicircular polyethylene foam arch members are used in a container to protect a part or the like from shock.

A plurality of resilient polyethylene foam cushions, each formed as an arch member 1 (Fig. 1), are interposed between, and in snug contact with, a part 2 to be cushioned and an outer container 3. When a dynamic load is applied normal to the top of the arch, each member 1 is initially very stiff at small displace- as displacement of the arch continues, ments; however, as displacement of the arch continues, the structural integrity of the arch member is reduced and it thus becomes softer. Since the arch member is bent rather than compressed, the effect of air flow is significantly reduced, providing lower acceleration values (see Fig. 2).
