A one piece stowage bin (10) has a generally rectangular, polygonal open-fronted box-type structure. Right and left end panels (14) and (18) rise up from the sides of the bottom panel (12) to form side walls. Three fold lines allow the stowage bin (10) to comprise the rear lower panel (22), the rear upper panel (26) and the top panel (30) of the stowage bin. Tenons (51), (52), (53), (54), (57), (58), (59), and (60) extend from the margins of the right and left end panels (14) and (18). Mortise pockets (63), (64), (65), (66), (71), (72), (73), and (74) are formed in the side margins of the rear upper panel 26 and the top panel (30). The mortises and tenons create interlocking mortise and tenon joints that do not require a bonding adhesive. Right and left formed angle brackets (38) and (40) secure the right and left end panels (14) and (18) to the top panel (30). Rear upper panel edge margins (27) and (28) and the top panel edge margins (30) and (32) contain outwardly extended bulges in the region of the mortise pockets that define minimum edge margins around each mortise pocket. Right extending minimum edge margin bulges (81), (82), (83), and (84) are staggered relative to left extending minimum edge margin bulges (89), (90), (91), and (92). Protrusions (120) extend into the interior of the mortise pockets from the sidewalls thereof to extend into the interior of the mortise pockets. The protrusions are sized to form an interference fit with the tenon tabs through a combination of spring deflection of the protrusions by the tenon tabs and local material removal from the tips of the protrusions as the tenons are inserted.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.]1. A self aligning mortise and tenon joint structure, comprising:(a) a mortise panel having portions defining at least one mortise pocket in the mortise panel, the mortise pocket having a perimeter wall;(b) a tenon panel comprising at least one flat tenon tab protruding from the tenon panel, the tenon tab having parallel, continuous, planar opposite sides devoid of transverse projections, recesses or hooks and of constant thickness, the tenon tab being shaped to correspond to the cross-sectional shape of the mortise pocket, said protruding tenon tab being insertable into said mortise pocket; and(c) at least one protrusion extending inwardly from the perimeter wall of the mortise pocket and into the interior of the mortise pocket, said protrusion being sized to form an interference fit with the flat tenon tab received within the mortise pocket through a combination of local material removal and spring deflection of the protrusion by the tenon tab, said protrusion acting as a self-tooling feature, capable of independently securing the tenon panel to the mortise panel.
