Abstract
A box for containing an article having a relatively stiff planar portion positioned flush against the front or back wall of the box and an internal tuck closure flap hinged to the front or back wall at an end of the box includes a tab hinged to the wall of the box opposite the closure flap hinge that folds inwardly so that when the closure flap is tucked inside the box to close off an end of the box the closure flap overlaps the tab. The tab prevents the article from hanging up on the edge of the closure flap or interfering with the tucking of the closure flap inside the box.
