Abstract
A filler flat construction for accommodating a plurality of fragile articles is provided which includes a plurality of article-accommodating cells arranged in side by side relation and forming substantially parallel rows. Adjacent cells in a row are separated by upstanding first shoulders, and corresponding cells in adjoining rows are separated by upright second shoulders. The first and second shoulders of a cell are angularly disposed and interconnected by upstanding hollow corner posts. Each post projects upwardly to a greater extent than the interconnected shoulders and the portion of the post which is elevated relative to the interconnected shoulders is provided with open side walls facing adjacent cells. The upper end portions of the open side walls of the post are interconnected by a cap section. Each cell includes a base section which is substantially delimited by wall segments extending divergently upwardly therefrom. The wall segments form surfaces of the shoulders and corner posts surrounding each cell.
