Abstract: A unitary structure for packaging a shock sensitive article within a container is provided. The structure has a side flange adapted to contact a side end portion of the article and a number of sidewall structures disposed about the periphery of the flange which extend over the side end portion of the article to contactingly support the article. Each of the sidewalls cushions the article against shocks by having an outboard wall which operably and supportingly contacts the container and a bridge section integral with the inboard wall and the outboard wall to cushioningly space the outboard wall from the inboard wall. The structure also includes a crush depression integral to the flange, inward of the sidewall and generally extending away from the article to supportingly contact a lateral sidewall of the container thereby forming a cushion distance. The crush button is configured to absorb shock loading of the article directed generally toward the sidewall.
