New arrangement for closing container boxes, characterized in that the edge of the mouth of the box, presents on each of its sides, a projection perpendicular to the plane of that and half thickness, from the outer plane in the middle of its length and of the interior plane in the other half, so that two opposite corners have that exterior projecting relief, and the other two interior inside the box; and on the other hand, on the cover, there are internal and external protrusions respectively, so that by juxtaposing each other they form a homogeneous contour of the box.
