Abstract
Abstract THE CONTAINER HAS TRIANGULAR SIDE PANELS AND GENERALLY RECTANGULAR END PANELS JOINED TO A PERIPHERAL FLANGE AT THE OPEN END. EACH TRIANGULAR SIDE PANEL HAS A TRIANGULAR RECESS AT EACH CORNER ADJACENT THE PERIPHERAL FLANGE. THE CONTAINER IS ARRANGED FOR NESTING INSIDE AN IDENTICAL CONTAINER AND THE RECESS RELIEVES THE DRAG AT THE CORNERS TO FACILITATE DENESTING. EACH RECESS ALSO PROVIDES AN UPRIGHT SHOULDER FOR LATERALLY ALIGNING THE NESTED CONTAINERS AND FOR GUIDING THE SUBJACENT CONTAINER WHEN DENESTED.
