Abstract
A dual carton formed from two substantially identical single cartons adhered to one another with adhesive which remains tacky after the cartons are separated. Each carton has a top and tuck-in flap, and the flaps of the two joined cartons are overlapped to seal the dual carton. The tuck-in portion of the flap of one carton is adhered to the top portion of the flap of the other carton with similar adhesive as used to join the cartons. After the cartons are separated, the cartons may be individually sealed by reusing the adhesive on the wall of one carton and on the tuck-in portion of the flap of the other carton to adhere the tuck-in portion of the flaps of the cartons to the outside of the wall opposite the wall from which the flaps extend. 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.
