Abstract
A carton made from a planar blank by gluing a glue tab hingedly connected to one panel to the inner surface of the adjacent panel. A coupon is hingedly connected to the glue tab by a tear line. Thus, at least a portion of the coupon makes planar abutting contact with the inner surface of the panel to which the glue tab is glued.
