A paperboard carton blank consisting of a first panel having side walls connected thereto by scored fold lines formed between a respective side wall and a respective edge of the first panel is provided. The blank further includes a second panel having side walls connected thereto by scored fold lines formed between a respective side wall and a respective edge of the second panel with one of the side walls of the first panel and one of the side walls of the second panel being congruent. The second panel additionally includes a region of weakness formed therein for allowing access to the interior of a formed carton. This region of weakness includes a tab extending from the second panel, at least one uncut line of weakness formed in the second panel and at least one cut line of weakness substantially parallel to the uncut line of weakness and formed in the second panel. The carton blank of this type is then used to form a paperboard carton having an opening feature which allows ready access to the contents of the carton. The opening feature preferably includes a pair of regions of weakness which cooperate to form an opening flap when desired. Each pair of regions of weakness include one uncut line of weakness and one cut line of weakness with the uncut lines being formed between the cut lines with each being formed in the external surface of the carton wall.
