Abstract: A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

Abstract: A system and method of at least partially forming reinforced packages. The method comprises moving a web of material in a downstream direction through a web forming section, at least partially forming at least a bag portion in the web of material during the moving the web of material through the web forming section, forming an attached web by adhering a construct to the bag portion of the web of material, and moving the attached web through a separating station. The moving the attached web can comprise moving the construct with the web of material. The method further can comprise separating the bag portion from a remainder of the web of material to form a bag during the moving the attached web through the separating station, the bag being attached to the construct.

Abstract: A machine and method for applying reinforcing strapping to bulk boxes. The machine includes a plurality of strapping head assemblies arranged in series, with each adapted to apply a strap in encircling relationship to a box at a predetermined location on the box. As the box advances through successive strapping head assemblies, straps are applied in predetermined spaced relationship on the box, until the desired number of straps have been applied. The number, spacing and tension of the straps may be quickly and easily adjusted. In an embodiment of the invention, the strapping head assemblies are arranged in pairs in individual modules. A recovery strapping head assembly is provided just prior to exit from the machine to apply any strapping missed by a preceding strapping head assembly.

Abstract: A shipping container having an internal plastic bag is described, as is the method of forming the container. A flat container blank if first formed. This differs from a conventional blank only in that it has blind score lines centered vertically on each of the end panels. Adhesive strips are placed on or adjacent the major score lines separating the face and end panels of the container. Either a flat or gusseted bag is then laid on the blank with a sealed bottom edge adjacent the outside edges of the bottom flaps of the container. An open end of the bag extends beyond the upper edge of the container. The blank is then folded along the blind score lines to form a partially assembled container that can be shipped flat. Final assembly can be readily done in the field. The container eliminates the need for field insertion of the bag where one is required.

Abstract: A method of forming a paper container uses a three ply corrugated material having at least one inner or outer sheet of paper that may be stretched or compressed circumferentially to permit subsequent rolling of the corrugated material about a mandrel. A flattening of the upper and lower edges of the corrugated material permit rolling and seaming operations to be used to assemble the bottom to the cup and to form a lip in the upper edge.

Abstract: A process for the automatic centering of a corrugated liner onto a corrugated blank, comprising the steps of providing a pair of opposed, longitudinally extending first fold lines in the blank with the distance between the first fold lines being the width of the liner and defining therebetween a central portion on the blank; providing a pair of longitudinally extending second fold lines adjacent the sides of the blank and that are parallel to the first fold lines, the first and second fold lines being spaced apart a distance equal to the thickness of the liner and an outer edge panel being defined on the blank between the second fold line and the sides of the blank; gluing the liner generally onto the central portion of the blank; folding the outer edge panels 90.degree. upwardly about the first fold line; and bending downwardly the outer edge panels another 90.degree. to contact the liner. A blank for use in such process is also disclosed.

Abstract: An improved forming block (10) is described for forming double packages including a liner enclosed within a carton. The forming block (10) includes a mandrel (12) having a free, open end (30) partially closed by an end piece (14).

Abstract: For the fabrication of a bag-in-box (BIB) package, there is first provided a semifinished, collapsed BIB package wherein a flattened bag is placed within a collapsed box and secured to at least one of its inside surfaces by means of an adhesive. After erecting the package, the bag is inflated into close internal contact with the box by introducing a gas under pressure through a fitment attached to the bag and projecting outwardly of the box. The opposite ends of the box are closed with sets of foldable end flaps, with the aid of an adhesive. Preferably, the bag is further secured to the inside surfaces of a pair of opposed ones of the four bottom end flaps of the box. The opposed pair of bottom flaps are held folded out during the introduction of the pressurized gas into the bag, in order that the bottom end portion of the inflated bag may make neat contact with the inside surfaces of the box. There is also disclosed herein an apparatus for thus fabricating the BIB package.
