ABSTRACT:
A box for containing goods during storing, mailing, or shipping. The box has at least one end panel secured to a body panel by a locking tab extendable through a slit in a closure flap of an end panel, so that the end panel cannot be unsecured without providing visible evidence of tampering. The locking tab is foldable for insertion through the slit, after which a surface of the locking tab engages the underside of the flap to prevent withdrawing the locking tab through the slit. Flanges on the locking tab engage the locked box, further preventing withdrawal of the locking tab. The locking tab is joined to the remainder of the box by perforated lines of selective weakness, which tear to provide visible evidence of tampering with the locking tab.
