A container lid has a top wall with a series of recessed areas that include therewithin a plurality of geometrical projections and a bottom wall that displays a plurality of recesses complementary in shape to the projections of the top wall whereby identically shaped lids may be stacked or cross-stacked in nested condition with the projections of one lid being received in the corresponding recesses of a superposed lid. The lid is adapted to be affixed to a container having four side pieces and a bottom piece, the configuration of the lid allowing a stacking or cross-stacking arrangement of lid-covered containers with their side pieces in the erected position as well as the stacking or cross-stacking of lid-covered containers with their side pieces in an inwardly folded position.

[ We claim:] [1.] A combination, of a lid and a five-piece container, said container consisting of four side pieces having upper edges and lower edges pivotally connected to side edges of a bottom piece so as to move between two positions including an erected position and an inwardly folded position; said bottom piece displaying, on its upper side, vertically extending post means at each corner thereof and, on its under side, a series of geometrical configurations of projecting ribs defining a plurality of cavities; said lid consisting of a body having a top wall and a bottom wall, said top wall displaying a peripheral edge defining therewithin a series of recessed areas including therewithin a plurality of geometrical projections, each projection having a top face extending in a plane substantially coinciding with said peripheral edge; said bottom wall displaying a plurality of geometrical recesses complementary in shape to that of a corresponding projection of said top wall whereby, when said side pieces of said five-piece container are in said erected position, the peripheral edge of said lid is engaged to said upper edges of said side pieces to cover said lid and lid covered containers may be stacked with said lid projections being received in corresponding cavities of the under side of a superposed container and whereby, when said side pieces of said container are in said inwardly folded position, said lid rests on said post means so that folded containers with lids thereon may be stacked with the projections of the lid being received in corresponding cavities of the under side of a superposed side-folded container.
