Abstract

A container for friable or granular material facilitates unfilled flat shipment of the container plus later user articulation, deployment and filling towards secure material containment. At least one containment cell is seated upon a bottom panel of a tray having side and end flaps for restrainably securing the cell. Emanating outwardly from the tray end flaps at attachment flap fold regions are attachment flaps that envelope interpositioned ones of juxtaposed cell end walls to restrainably secure them. With at least a portion of a side wall of an articulatable cell preliminarily attached to a tray side flap that may be articulated with respect to the bottom panel, folding the tray side flap down to a first position generally coplanar with the bottom panel enables the cell to collapse into a pair of juxtaposed stacked layers. Moving the tray side flap to a second position generally perpendicular to the bottom panel and articulation of the attached cells creates material fillable positions with the bottom region of the cells seated upon the bottom panel of the tray. A master pack carton is provided for receiving a plurality of trays with filled containment cells.
