Abstract:
In a carton having an interior, a vertical side wall and a paperboard pour spout assembly comprising a pour spout front panel formed from a section of the side wall and hingedly connected thereto along a horizontal fold line for pivoting between a closed position and an open position, the pour spout front panel have a pair of opposed generally vertical side edges and an upper edge bridging the side edges, a perimeter of the pour spout front panel on an interior surface of the side wall defining a pour spout opening having two opposed vertical edges, a cutout above the pour spout front panel to enable on to grasp the upper edge of the pour spout front panel, a pour spout back panel adhered to the interior surface of the pour spout front panel, a pair of wings hingedly connected to the pour spout back panel along opposed parallel fold lines, and a vertical backboard adhered to the interior surface of the side wall such that the vertical backboard occludes the cutout, the improvement wherein the pour spout back panel, wings and vertical backboard are provided by a separate component comprising a first section comprising the pour spout back panel and the wings, and a second section comprising the vertical backboard the first section having a sinuous first upper edge extending along a top edge of the pour spout back panel and along an upper margin of each wing, and the second section hang a second upper edge and a sinuous second lower edge, the separate component having a frangible score separating the first and second sections, the frangible score extending entirely along the sinuous second lower edge and partially along the sinuous first upper edge to include the top edge of the pour spout back panel and a portion of the upper margins of the wings, the vertical backboard having a pair of prongs along the sinuous second lower edge that project downwardly into corresponding indentations in the top edge of the pour spout back panel along the sinuous first upper edge, each of the prongs defining a narrow channel between an edge of each of the prongs and one vertical edge of the two opposed vertical edges of the pour spout opening, the narrow channel for receiving one wing of the pair of wings, whereby the one wing is held in abutting relationship with the one vertical edge in a plane that is substantially perpendicular to the plane of the side wall, the vertical backboard being cut-off entirely along the upper edge thereof.
