(54) Carton closure interlock


(57) This relates to a closure interlock between closure panels of a carton of the wrap around type. The closure interlock provides for a primary locking tab on an outer one of the closure panels and a secondary locking tab on the inner one of the closure panels whereby a primary lock and a secondary lock may be formed generally in alignment longitudinally of the closure interlock thus providing for a savings of carton forming stock corresponding to the normal spacing of the primary lock and the secondary lock transversely of the general line of the closure interlock. The secondary locking tab passes through the outer closure panel and returns generally into the opening from which it is formed.
