A method for producing reusable packaging from a carton. A rectangular blank has sides X and Y, a total area xy, 2(a+h)≤x≤3(a+h)+a, and y−2(h+r)≤b≤y, where a and b are side dimensions, h is height, and r is width, or width reduced by height h, of the periphery region R of the finished packaging. The method includes: producing folding lines B in the blank parallel to a first side Y at these distances from the latter: B.sub.1: a.sub.1=h; B.sub.2: a.sub.2=h+a; B.sub.3: a.sub.3=2h+a; severing of two severing lines T, each starting from opposite sides X, along one of the folding lines B, or the extension thereof; selecting the distance between two end points E.sub.T of the severing lines T which are closer to an axis of symmetry S.sub.1, which is parallel to the side X, such that the distance corresponds to a side B″ of the finished packaging or length of a side M of a packaging insert.

A method and system are disclosed for forming a can from a re-configurable blank. A blank is also disclosed that may be a paper based blank and may be of multi-layer construction. The method may comprise: (a) supporting the blank in a first orientation; (b) positioning a first portion of an outward facing surface of a blank support device proximate a first portion of the blank while the blank is in the first orientation; (c) while the first portion of the blank is in the first orientation, rotating a second portion of the blank around a second portion of the outward facing surface of the blank support device; and (d) rotating a third portion of the blank from the first orientation, around a third portion of the outward facing surface of the blank support device. A generally tubular side wall may thus be formed for a can.

An apparatus for use in the packaging industry comprises a first member for collecting a tubular box in a flattened configuration from a store positions the tubular box in a lowered position, retaining the box with first suction means at a first wall of the box. A second member, a third member and a fourth member are provided for movement of a fifth member which, when activated in rotation, abuts and retains, via second suction means a second wall of the tubular box, causing it to rotate with respect to the first wall, to open out the tubular box. A sixth member is included, with third suction means which is moved by a system to abut and retain the box in the opened-out configuration and transfer it, following the disengagement of the first member and of the fifth member, at a receiving station.

A supply apparatus that supplies corrugated cardboard sheets to a supply position in a box-making section that opens folded corrugated cardboard sheets and makes boxes. The supply apparatus comprises a conveying unit, a drive unit, and a control unit. The conveying unit conveys a plurality of the corrugated cardboard sheets to the supply position with the corrugated cardboard sheets stacked. The drive unit drives the conveying unit. A controller, serving as the control unit, estimates the total quantity of the plurality of stacked corrugated cardboard sheets on a conveying surface of the conveying unit. The controller acquires a value pertaining to the drive force of the drive unit when the drive unit drives the conveying unit, and estimates the total quantity of the plurality of stacked corrugated cardboard sheets on the basis of the acquired value.

A continuous case blank delivery system, its function and use are provided. The main components of the system include a staging area, an elevator area, a safety door positioned therebetween, and a carriage movable therebetween when the safety door is in the open position. The elevator has a right side wall a left side wall and an elevator platform. The platform is vertically moveable between a lowered position and a predetermined height. In the lowered position the elevator platform is below the height of the carriage. The walls each define a plurality of support finger housings, each of which contain an extendable support finger. When the elevator platform is in the lowered position each support finger is retracted and contained entirely within its housing. When the elevator reaches a predetermined height each support finger is extended.

A method and apparatus are disclosed for forming containers. The containers may be cans, including composite cans. The apparatus may include a cylindrical mandrel and a blank may be formed into a cylindrical tube around the mandrel. Rotational apparatuses may engage portions of a blank that may be in a flat configuration and may rotate the portions around the outward cylindrical surface of the mandrel. Free edges of the tubular blank may be sealed by a sealing strip that may be T-shaped in cross section. A cup may be installed in an end opening, such as a bottom end, of the cylindrical tube. The cup may be sealed in the end opening by a seaming process using a seaming apparatus.

A box forming machine includes a converter assembly, a fold assembly, and an attachment assembly. The converter assembly converts sheet material into a box template. The fold assembly engages a first end of the box template and moves the first end of the box template to a predetermined position. The attachment assembly engages a second end of the box template and moves the second end of the box template toward and into engagement with the first end of the box template to attach the first and second ends of the box template together.

A paper box package forming apparatus includes a continuous feeding device, a box folding mechanism and a cover sealing mechanism. The continuous feeding device includes a paperboard stacking frame, an adsorption mechanism and a roll extrusion conveying mechanism. A paperboard is absorbed from a back side of the paperboard stacking frame through the adsorption mechanism and conveyed to a box folding device through the roll extrusion conveying mechanism. The box folding device includes a downward-pressing inner punch, a box folding outer mold and a pushing mechanism. The pushing mechanism conveys a bottom box to the cover sealing mechanism. The downward-pressing and attaching mechanism includes downward-pressing driving mechanism, a top-pressing plate, side-pressing plates and overturning cylinders. The side-pressing plates are hinged to side edges of the top-pressing plate through the driving of the overturning cylinders.

The present invention relates generally to a new and improved paper-based container. More specifically, the invention relates to a paper-based container that is comprised of a relatively low-density polyethylene coating on one or both surfaces of the container and at least two skive flaps, wherein each of said skive flaps is created during the manufacturing process. The skive flap further comprises at least one leading edge of the container body, and prevents unwanted moisture from entering the container and the contents of the container from saturating the paper-based material. One skive flap is preferably folded in a manner in which a portion of the outside surface of the container is adhered to the inside surface, a second skive flap is adhered to the outside surface and a third skive is formed at the bottom of the container.
