  • Patent number: 4899918
    Abstract: A dispensing carton in which a roll film is contained includes a box consisting of a bottom panel, a rear panel, a front panel, both side panels and an opening formed in an upper portion thereof, a lid member which is hingedly joined to an upper end of the rear panel, and a front flange joined to an end of the lid member to overlap the front panel when the lid member is closed. A cutter is provided in an end of the front flange and an intermediate portion of the cutter is protruded toward a base of the box. When the film pulled out from the box is led between the front flange and the front panel and is further pulled in the horizontal direction with the lid member being closed, the middle portion of the film is cut by the protruded portion of the cutter and the cutting operation of the film is advanced along the cutter so that the film is smoothly and completely cut into a slightly V-letter shape when the film is further pulled in the horizontal direction as it is.
