This invention is a paperboard box and a lid having a paper with a design placed on the outside surface. The paper is held in position by being glued to the inside of the finished carton. The box or lid has four squared corners. The finished decorative box has adhesive on the interior panels and may be shipped in flat form and erected at or near the point of use. Because the paper is thick it is difficult to form square corners on the box or lid. The box or lid has a paperboard web between a side panel and an end panel which is folded to make a square corner. It has been found that a slit can be cut in the paper bisecting the corner which will allow the paper to be folded without bunching and making an attractive square corner. Once the slit is cut in the paper the side and end panels can be folded to produce a square corner without any bulging paper. The bulging paper is not attractive as a gift-wrap box and also may prevent the locking of the corner as required to form a box and lid with square corners.

Method of forming a paperboard blank with attached giftwrapping paper into one component of a giftbox with square corners

A multiply blank for forminmg a tray base or lid comprising a a a flat paperboard substrate (S) to which an outer decorative sheet (16) is secured. The paperboard substrate comprises a main panel (m) having opposed side edges to each of which a pair of side wall panels (s) is hinged for forming respectively outer and inner side walls when the tray base or lid is erected, and having opposed end edges to which a pair of end wall panels (e) is hinged for forming respectively outer and inner end walls when the tray base or lid is erected, and foldable web panels (w) interconnecting the outer side- and end wall panels. The decorative sheet is adhered to the flat paperboard substrate along strips of adhesive extending along those side- and end wall panels which become the inner side- and end walls when the tray base or lid is erected. The decorative sheet is further adhered to the foldable web panels (w) between the mentioned longitudinal and transverse strips of adhesive.

Multi-ply carton, carton blank & method of forming the blank

A multiply carton tray base or lid comprising a paperboard substrate (S) to which an outer sheet material (16) is secured. The tray has a main panel (m) across which the sheet material is stretched so that it is normally out of contact with a substantial part of the main panel and is secured to the tray only at locations internally of the carton side panels (s) and end panels (e) and not at all to the main panel (m).

Multi-ply carton, blank and method of forming the blank

An apparatus (10) is provided for erecting boxes from blanks (11) having sides panels (13) with three score lines (20, 22 and 24). The apparatus has a base plate (40), two side folding mechanisms (44) and two end folding mechanisms (45). The side folding mechanisms have a proximal plate (51) pivotally mounted to the base plate, an intermediary plate (53) pivotally mounted to the proximal plate, and a distal plate (55) pivotally mounted to the intermediary plate. Linkage (68) coupled to a handle (76) actuates the movement of the proximal, intermediary and distal plates.
