A method of forming a box is discussed. A sheet of foldable material has a central region and tabs extending from the central region around its perimeter. Each tab includes a first fold line at the central region, and second and third spaced apart fold lines parallel to the first fold line. A reinforcement ring has a perimeter corresponding to the perimeter of the central region and a thickness greater than a thickness of the sheet. The reinforcement ring is disposed on the central region. Each tab is folded along the first fold line to extend transversely to the central region against the reinforcement ring, along the second fold line to extend inwardly over the reinforcement ring, and along the third fold line to extend transversely to the central region against the reinforcement ring. The tabs folded around the reinforcement ring define side wall(s) of the box.

A machine for forming and printing cardboard boxes, each box including a bottom wall, two pairs of side walls and a closing wall, the machine includes supply means for supplying a continuous web of cardboard, first cutting means for cutting the continuous web, that are adapted to form an elongate element with upper and lower surfaces, second cutting and creasing means for forming, in the elongate element, a first panel configured to define the first pair of side walls, the bottom wall and the closing wall, and second and third separate panels configured to define the second pair of side walls of the box. The machine also includes printing means interposed between the first cutting means and the second cutting and creasing means. The printing means have at least one lower and upper printing unit, adapted to print on the lower and upper surfaces of the elongate element respectively.

A packing box has a bottom panel, end panels raised from first edges of the bottom panel, side panels arranged adjacently to the end panels, edge panels connected to side edges of the end panels via outer panel fold lines, fold-back panels arranged on inner side surfaces of the edge panels, inner panels arranged on inner side surfaces of the end panels, and reinforcing panels continuously formed with the fold-back panels via first fold lines and the inner panels via second fold lines. The reinforcing panel 16 is formed in an inwardly projecting manner between the fold-back panel and the inner panel. Any of the first and second fold lines positioned on a side closer to the outer panel fold line than a projecting top portion is arranged away from the outer panel fold line by a distance.

The tabs folded around the reinforcement ring define side wall(s) of the box.

A frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.

The present invention provides a shaping tool for shaping a package formed of a foldable blank, the tool comprising: an overhead conveyor comprising a plurality of downwardly protruding spaced apart counter-means; a first conveyor extending between a receiving end towards an output end, and adapted to receive the foldable blank from an incoming conveying line at the receiving end and to position the foldable blank below one of the downwardly protruding counter-means; a shaping station extending away from the receiving end, the shaping station comprising: a pair of parallel shaping tracks, each positioned on one side of the first conveyor, the pair of generally parallel shaping tracks comprising a plurality of pairs of independently movable shaping lugs, each pair of shaping lugs having a predetermined shape and adapted to receive one of the foldable blanks there-between; the pair of lugs movable towards each other to form a package having a desired shape.

A box having a base wall having an outer surface defined by a central region of a folded sheet, and one or more side walls forming a closed perimeter and extending from an inner surface of the base wall. Each side wall has spaced apart inner and outer layers being defined by a folded tab of the folded sheet, the folded tab defining an enclosure. A reinforcement ring is received in the enclosure defined by the folded tabs of the side wall(s). The reinforcement ring has a thickness greater than that of the folded sheet. A method of forming a box is also discussed.

A repulpable moisture resistant poultry box having a composite structure with a fluted medium, a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium. The backing boards and the fluted medium are impregnated with a hydrogenated triglyceride. The backing boards each have an outer surface coated with an emulsion of hydrogenated triglyceride and styrene acrylic to provide moisture resistance repulpable and recyclable box.

A method for wrapping a cardboard box with a wrapping sheet, includes: providing a cardboard box with a continuous edge delimiting an opening of the box; providing a wrapping sheet; coupling the box and the sheet; placing on a supporting surface the box coupled to the sheet so that the opening of the box is opposed to the supporting surface; positioning a closing system on the continuous edge of the box so as to define a closed chamber that is comprised between the box and the closing system; supplying air inside the closed chamber so as to make the box adhere to the sheet.

A packing box has a bottom panel, end panels raised from first edges of the bottom panel, side panels arranged adjacently to the end panels, edge panels connected to side edges of the end panels via outer panel fold lines, fold-back panels arranged on inner side surfaces of the edge panels, inner panels arranged on inner side surfaces of the end panels, and reinforcing panels continuously formed with the fold-back panels via first fold lines and the inner panels via second fold lines. The reinforcing panel 16 is formed in an inwardly projecting manner between the fold-back panel and the inner panel. Any of the first and second fold lines positioned on a side closer to the outer panel fold line than a projecting top portion is arranged away from the outer panel fold line by a distance.
