Abstract: A container includes a rectangular tray and a removable lid. Each short side of the tray is constructed of two closely spaced walls or partitions and the lid is provided with extensions each of which projects through a slot in the narrow connecting section that joins each pair of short side walls and extends into the space therebetween. With a plurality of these tray in a stack, the connecting sections provide ledges on which each of these trays supports the adjacent higher tray. For each pair of short side walls, the inner one thereof is provided with a panel at both ends thereof. Each panel has an end or distal section that overlaps and is cemented to the adjacent long side wall and a joining or connecting section that extends diagonally between this long side wall and the main central section of the short wall. These joining sections serve to support the adjacent upper tray in the stack.
