Abstract
A carton having a tuck-in flap extending from each wall which travels substantially parallel to the path of travel through a tax-stamping machine. At least one tuck-in flap is provided with a tapered tuck-in portion which is positioned and dimensioned so that the hold-down guide positioned to hold down the shorter of a pair of lap flaps of a conventional cigarette carton will hold down the tuck-in flap having the taper as if it were a short lap flap. Moreover, the longer portion of the tapered tuck-in flap is properly held down as well, without being snagged by the hold-down guide. An additional extension panel may be provided along the free edge of the tuck-in portion of either or both tuck-in flaps. The tuck-in portion may be folded under the top closure portion of the tuck-in flap, and the additional extension panel tucked between the cigarette packs in the carton and the wall from which the folded tuck-in flap extends. The folded tuck-in flap thus resembles a short lap flap which may be sufficiently held down by the hold-down guide for a short lap flap.
