Abstract
A blank for forming a parallelepipedal box or a parallelepipedal box element is constructed with a removal strip in such a manner that parallel tear lines extend through three connected wall sections of the blank. The tear lines end in one wall section at an articulation area. The tear lines delimit the removal strip which can be torn out of a finished pack or box and upon which a pulling force can be exerted in such a manner that the removal strip is bent about the articulation area, thus causing objects to be lifted from the box by the removal strip.
