Abstract
Abstract A cushion for packaging an article in a container comprising flexible foam material and a pliable non-porous cover contiguously surrounding the foam material. The cover may include a lip which may be secured to the container. A plurality of air vents in the cover adjacent the lip control the flow of air out of the cover when the foam is compressed. By controlling the air flow out of the foam material, the dynamic resistance of the cushion may be increased, so that more force is absorbed by the cushion when an external force is applied to the container than would be absorbed if exposed foam material were used. A plurality of cushions may be secured to the inside of the container to hold the article snugly in place.
