Abstract: A void filler including a casing with opposed vertical side walls and opposed face walls. The casing confines an expandable and collapsible core formed of centrally folded strips with the opposed ends of each strip secured to the opposed side walls. The strips are formed in two facing groups, each of a general chevron pattern with the strips collapsing entirely within the casing upon an inward movement of the opposed side walls into parallel overlying engagement, the strips folding between the side walls and defining a minimal layering of panels between the side walls.

Abstract: A portable disposable container comprising a top closure including two inner centrally apertured panels independently lockable across the open upper end of the container in overlying relation to each other. An imperforate closure panel includes a remote handle flap for manipulation of the top container. The closure panel, upon a closing of the container, overlies the inner panels, sealing the openings therein. The handle flap is positioned immediately adjacent a similarly configured handle panel and is locked thereto by a locking extension wrapped about both handles components.
