Opposite these closures is the one according to the invention Bottom closure has the advantage that the 4 uniform tabs forming the bottom of the box are designed so that When the box is closed, these are initially bent by 160 degrees around their bending edges into the interior of the box body, in order to then return to the old position through the endeavors inherent in the cardboard material, to automatically superimpose one another, that the bottom is completely closed. With flush shaped flaps it may be necessary; the self-acting closing movement to support the flap by alternating gentle pressure on the long edges of the box.
