ABSTRACT:
A foldable box having, in addition to primary folding lines and flat segments, a number of latent score lines in a direction perpendicular to the length of the unfolded box. The latent score lines do not interfere with the formation and the normal function of the box. However, they serve to facilitate an irreversible destruction of the box, when the box is forced to be folded into a log-like structure.
