ABSTRACT:
A dispensing carton in which a film wound cylindrically is contained includes a bottom panel, a rear panel, a front panel, both side panels, a lid member which is hingedly joined to the rear panel, a front flange joined to an end of the lid member to overlap the front panel when said lid member is closed, and a cutter mounted along an end of the front flange. The front flange includes a convex edge including, for example, a V-shaped edge. A saw-tooth edge of the cutter mounted along the end of the front flange is arranged into a convex shape such as V-shape. A length from the tip of at least one tooth of the saw-tooth edge nearest to a base of the box to the bottom of a gullet adjacent to the tooth is longer than a length from the tip of other teeth to the bottom of gullets adjacent to the other teeth. When the film is pulled out of the carton and further pulled in the horizontal direction or twisted while being pulled, the tooth of the cutter nearest to the base of the box first cuts into the film. Then, when the film is further pulled, the cut of the film is extended along the arrangement of teeth of the saw-tooth edge so that film is cut easily and completely while keeping the film spread horizontally.
