ABSTRACT:
A dispensing carton for a web in roll form wherein the lid is closed on the roll with an end of the web emerging between the lid and the wall of the carton. The wall of the carton is provided with a longitudinal relatively stiff strip, preferably of plastic, adjacent the opening in the carton through which the web is drawn. The strip has a serrated edge for tearing the web after a desired length is drawn. The strip is extended onto adjacent sealing or dust flaps of the carton which are secured to the end walls of the carton so that when the sealing or dust flaps are folded into engagement with the end walls of the carton during manufacture of the carton, reinforced corners for the carton are formed at the areas of greatest stress where the web is first torn against the serrated edge, or reinforcement is obtained by using a multi-ply underlay for supporting serrated edge strip. The serrated edge strip may be mounted to extend beyond a side wall or a bottom wall of the carton. The invention also includes the method of making the carton having a serrated web in which a pair of cartons are juxtaposed or a single blank is die cut in the form of a pair of cartons. A strip is laid at the seam or that area between the cartons which is to form the upper edge of the wall adjacent the opening in the finished cartons and the blanks for the two cartons and the strip are cut apart by a member which forms matching serrated edges as well as the reinforcements above described. The two cartons thus separated may then be separately formed by appropriate machinery and filled with the roll of material to be kept in the carton and withdrawn therefrom.
