Packaging for fragile articles within container

A unitary structure for packaging a shock sensitive article within a container comprising:

• a side flange having a peripheral portion;
• a plurality of peripheral sidewall structures of flexible material, said sidewall structures including an inboard wall integral with said peripheral portion with said sidewall structures arranged about the peripheral portion to form an enclosure about an end portion of the article, said sidewall structures including an outboard wall having a distal end and a proximate end, and a bridge section integral with said inboard wall and said proximate end of said outboard wall and spacing said outboard wall from said inboard wall to form a hollow cushion space, said bridge section forming biasing means to resiliently restrict the movement of said inboard wall toward said outboard wall upon the shock loading of said article;
• lands extending outward from said flange to separate said sidewall structures form each other;
• and
• a crush depression integral with said flange, inward of said first wall and generally extending in a first direction from said flange away from the article to supportingly contact a sidewall of the container and form a cushion distance, said button including means for absorbing shock loading of the article generally in the first direction.
