ABSTRACT:
This relates to a lock arrangement particularly adapted for use in locking together closure panels of paper board cartons and the like. The lock arrangement utilizes a conventional basic type of lock including a primary locking tab and a secondary locking tab. The primary locking tab engages in a cutout having as part of its boundary a straight line primary locking shoulder. The new feature of the lock arrangement is an arrangement for receiving the secondary locking tab. This arrangement is in the form of a cut line which will define an opening through the associated closure panel and also define a secondary locking ear for engagement beyond a prong on the secondary locking tab. The closure panel in which the cutout and the cut line are formed is provided adjacent the cut line either with an opening or a hinged locking flap with there being between the cutout and either the opening or the locking flap a narrow strap. When a nose of the secondary locking tab engages the panel between the narrow strap and the cut line, the panel is locally bowed through a twisting of the narrow strap facilitating the opening of the panel along the cut line so as to automatically receive the nose of the secondary locking tab.
