A modular test tube rack for assembly with similarly constructed racks comprise a flat rectangular body displaying, in a first position, a series of wells extending from its top wall to its bottom wall and adapt to receive tubes therein. A pair of handles vertically extend at opposite end walls of the body, each handle having a lower portion adapted to tightly engage an extension on each end wall and a hand gripping upper portion. The lower portion has a bottom edge configured to anchor with the top edge of the handle of an underposed similarly constructed rack to thereby enable a stacking of two more of these racks. In one embodiment, the body displays a second series of wells extending from the bottom wall to the top wall whereby the body, when in a second position reversed relative to the first position, may also receive test tubes, the handles being reversably mountable to the end wall extension to still enable a stacking of racks in the second position.

The container of claim 1 wherein each of said four corner panels defines a tab recess having a size and shape corresponding to one of said interlocking tabs formed in each corner panel above the apertures, whereby said interlocking tabs of the similar container extending through the apertures of the container can be received by the recesses. 6. The container of claim 1 further comprising: two movable half covers, each extending from the top of a corresponding one of said side panels, the half covers having a predetermined thickness; a base extension formed on each interlocking tab, wherein the base extension corresponds in height to the thickness of said half covers, wherein each of said half covers defines a tab channel that is arranged to receive the interlocking tabs of the container when the half covers are folded over the open container. 7. The container of claim 1 wherein said container defines a plurality of ventilation holes. 8. The container of claim 1 further comprising one or more lowered regions of side wall or end wall whereby the height of a portion of said side or end wall is lower than that portion of the side wall or end wall to which the corner panel is attached. 9. The container of claim 1 wherein the container is formed from at least three separate blanks. 10. The container of claim 1 wherein the container is formed from a main blank and two secondary blanks, the main blank comprising the bottom panel and side panels, and each of the secondary blanks comprising one of the end panels and at least two of the corner panels. 11. The container of claim 10 wherein each secondary blank further comprises an extension flap extending at a right angle from the end panel of the corresponding secondary blank and an attachment flap secured to the end panel of the corresponding secondary blank. 12. The container of claim 10 wherein each secondary blank further comprises a corner flap extending from the end panel, and an attachment flap extending from each of the corner panels, the attachment flap being secured to the side panel of the corresponding secondary blank. 13. The container of claim 10 wherein the secondary blanks are formed of a heavier material than the main blank, thereby providing the container with increased vertical stacking strength. 14. The container of claim 1 further comprising: a corrugated cardboard top defining a plurality of similar tab channels formed therein and arranged to cover the cardboard container and receive the interlocking tabs of the stackable self-aligning corrugated cardboard container that it covers; and, a base extension, of a thickness corresponding to the thickness of said top, formed below the wide base of a corresponding one of said tabs, wherein the corresponding tab is of a sufficient height to assure that the entire corresponding tab will protrude through said top. 15. A stackable, self-aligning, box formed from a single sheet of foldable material comprising: a rectangular bottom panel having a pair of opposite ends and a pair of opposite sides generally perpendicular to said opposite sides; two rectangular side panels, each with two ends and two foldable end flaps, extending upwardly from the opposite sides of said bottom panel; two rectangular end panels extending upwardly to approximately the same height as said side panels, from opposite sides of said bottom panel, said end panels meeting said ends of said side panels to form four corners; four corner panels of the same height as said end panels, each corner panel being folded from one of the end flaps, extending diagonally across each corner, and having one end attached to the corresponding end panel and the other end attached to one of the side panels from which the flap extends; and at least four shaped interlocking tabs, each tab having a relatively wide
