Abstract
This relates to a clasp lock for interlocking two overlapping closure panels of a carton. The clasp lock is made adjustable to compensate for different sizes of articles being packaged in the same carton. In order to effect the adjustment of the lock between the closure panels, the primary locking tab is of a stepped height and the closure panel carrying the primary locking shoulders is cut so that the primary locking shoulders are also stepped with respect to the free edge of the associated closure panel. In the interlocking of the closure panel portions, the primary locking tab will automatically engage the proper primary locking shoulder in accordance with the objects which are being packaged within the carton.
