Abstract
A dual carton formed from two cartons each having at least one pair of opposed top flaps. One carton has an extended top flap which extends over the other carton when the cartons are positioned adjacent one another such that the extended top flap may be secured to the top flaps of the other carton to thereby join the two cartons to form a dual carton. The extended portion of the extended top flap is joined to the remainder of the extended top flap along a weakened line to facilitate later separation of the two joined cartons. The dual carton may be a cigarette carton of dimensions compatible with tax-stamping machinery and temporarily sealed in such a manner as to facilitate the opening and later resealing of the carton for tax-stamping purposes.
