Abstract: A structure for packaging a shock sensitive article within a container having a plurality of panels includes a flange having a bottom surface, and a peripheral portion including a pair of opposing sides, and the flange defines an article containing space. A first sidewall and a second sidewall are located along the opposing sides of the flange, the first and second sidewalls each include an inboard wall integral with the peripheral portion of the flange, an outboard wall having an article end and a container end depending from the bottom surface, and a bridge portion joining corresponding edges of the inboard wall and the outboard wall to form a cushion space. At least one column formation is formed integrally with the first sidewall and the second sidewall, each of the column formations has an inside wall and an outside wall, and extends from the inboard wall into the article containing space to be closer to the opposing column formation than the inboard walls are to each other.
