ABSTRACT:
This relates to a closure interlock for closure panels of cartons of the wrap around type. Each closure interlock includes a primary locking tab on an outer closure panel and a secondary locking tab and primary and secondary locking shoulders on an inner closure panel. The locking tabs are generally in alignment and the locking shoulders are spaced a very short distance transversely of the length of the closure interlock. This permits a very shallow angle of entry of the secondary locking tabs so that the closure interlocks may be aligned with and generally underlie items being packaged within the associated carton.
