A shipping and storage container for spent cylindraceous cartridges comprising

• a pair of sidewalls
• a pair of endwalls
• a top wall
• a bottom wall
• wherein the top wall is formed by four co-operating flaps, three of said four co-operating flaps each being provided with apertures, a first pair of said four co-operating flaps extending from said side walls and a second pair of said four co-operating flaps extending from said end walls,
• a first flap of said first pair having an aperture of a predetermined size formed therein, said first flap of said first pair being folded closed first so that it becomes part of the topwall of the container,
• a first flap of said second pair closing over the first flap of said first pair so as to partially overlap said first flap of said first pair in such a manner that the aperture in said first flap of said first pair remains uncovered,
• a second flap of said second pair being folded over said first flap of said first pair so that said apertures in said first flap of said first pair and in the second flap of said second pair are in registry,
• a second flap of said first pair being folded over said previously folded flaps so that all three apertures of the flaps forming the assembled topwall are in registry, to form a port in said topwall of said container,
• said second flap of said first pair being locked into said container to prevent inadvertent opening of said container,
• and wherein said second flap of said second pair is of sufficient length to permit said second flap of said second pair to be folded back upon itself to cover the aperture contained in said second flap of said second pair.
