ABSTRACT:
A folding carton has an insertion flap attached to a crease line on a panel of a carton body. The insertion flap has a second crease line parallel to the first within which lies a slot. The slot is used in conjunction with a second added flap attached to the carton body, which added flap is inserted, and attached in a permanent manner so that a portion of the insertion flap becomes a reusable closure means when the added flap is detached from the body.
