A container features a pair of stacking features on its top and bottom walls enabling a plurality of such containers to be disposed in a vertically stacked configuration. One of these stacking features is a protrusion with a tip spaced from an outer surface of the respective wall and opposite sides depending from the tip on either side thereof towards the wall's outer surface, and the other one is a groove with a base recessed from an outer surface of the respective wall and opposite sides of the groove extending from the base on either side thereof towards the wall's outer surface. The groove of one such container is thus arranged to matingly receive the protrusion of another such container so that the two containers are interconnectable in the vertically stacked configuration.
