ABSTRACT:
A box includes one or more cover elements having a closure panel from which a tongue extends. The tongue can be introduced into the box as the cover is closed and through the tongue an elongated window is provided, at and near which a hole is formed through the cover closure panel. Under the cover closure panel there are provided flaps which project from one or more main panels of the box. The flaps being folded and arranged under the closure panel as the related cover is closed. From at least one of the flaps there extends a hook shaped tooth which projects in the window and is locked therein. The tooth being separated by its respective flaps by way of a preset breakage line, so that the tooth operates as a seal element and is torn from the flap as the cover is opened. The presence of the tooth and accordingly the untampered condition of the box can be checked through the hole formed through the closure panel.
