Abstract: A machine is configured to transition a blank having a fold line extending therein directly between first and second panels thereof. The machine includes a side support configured to abut an underside of the first panel, and a vacuum gripper including a suction cup that is extendable into suctioning engagement with an underside of the second panel, and that is retractable while maintaining suctioning engagement with the underside of the second panel. The vacuum gripper is configured to pull the second panel downward by retraction of the suction cup while maintaining suctioning engagement with the underside of the second panel and while the side support abuts the first panel, whereby the first panel bends along the fold line upwardly relative to the second panel. A rod is extendable into engagement with the underside of the first panel for further bending of the first panel along the fold line.

Abstract: A method and device for end closing tubular wrappings of products, whereby the arms of a scissor-type parting device, once inserted in a closed position inside an end portion of a tubular wrapping, are allowed to part, and are pushed by springs into a fully open position throughout an extraction stroke to crease the end portion and enable the end portion to be pressed taut and accurately by the opposing thrust of two folding-sealing members.

Abstract: A system for re-assembling collapsed collapsible topless containers which have four side walls pivotal to each other and a pallet. The system unfolds a collapsed container by lifting it up by one of the sides. The unfolded container is transferred to an assembling sub-unit which tips the unfolded container upright and deposits it on the pallet which releasably engages two opposing side walls.

Abstract: A reusable assembled box and a method of transport thereof are provided, in that the box has a base with greater strength, and is capable of disassembled into compact pieces facilitating sending back thereof, thus reducing a transport cost and enabling reuse of the box in higher frequency. The box comprises a first member, a second member, and coupling members. The first member is in a substantially rectangular shape, comprises a base and a pair of opposing side walls folded up from the base. The second member is in a substantially rectangular shape and comprises a base, overlain on the base of the first member, in a shape substantially identical to that of the first member, and a pair of side walls adjacent to the walls of the first member. The coupling members detachably couples upper end corners of adjacent side walls of the first and second members assembled into a box by overlaying the bases of the first and second members.

Abstract: An improved method for packaging perishable goods comprises an inner insulating container that is quickly and easily formed from a flat sheet of metalized bubble pack material to a finished state that very closely approximates the size and dimensions of the carton. The constructed inner container can be quickly collapsed and reconstructed to improve the stackability and diminish the amount of space required to store the containers prior to use.

Abstract: A collapsible container (30) includes a collapsible section (31), having orthogonally shaped walls (3), each having a fold line (6) extending in a common direction from a bottom corner (7) on a bottom edge (8) to a diagonally opposite top corner (9) on a top edge (10). A base section (32) and top section (33) which may or may not be collapsible are attached to opposite sides of the collapsible section (31). The container (30) may be collapsed or extended by twisting the base section (32) relative to the top section (33). It thus provides, for example, a convenient means for containing products such as concentrates or two pot mixes, which can be mixed within the container (30) when extended.

Abstract: A collapsible bottomless storage pen having a continuous articulated peripheral wall including parallel sidewalls and interconnecting end walls. Each end wall includes a bend line. Interior connecting flaps are hingedly attached to the end walls and cooperatively engage each other to retain the pen in an operative position. The end walls and connecting flaps are sized to permit folding of the pen to the length of the sidewalls, such that the connecting flaps and end walls are parallel to and between the parallel collapsed sidewalls.

Abstract: A spreader device for the lower end of a forming and filling tube of a form, fill and seal machine has an operator located on the outside of the upper end of the tube. The operator may effect oscillations causing the finger to swing into and out of spreading position, or the operator may cause the finger to reciprocate into and out of spreading position.

Abstract: Disclosed are carton assembling method and equipment for sucking and taking out flatwise folded cartons one by one from a magazine by means of suction cups, unfolding each carton squarely on a conveyance path while transferring it downward along a rotative path, and supplying the thus-unfolded cartons to an encasing machine by means of a conveyance mechanism. Each carton is held squarely by a pair of stoppers, utilizing its reaction force acting in the returning direction. Thereafter, the carton is reverse-folded against such reaction force and then unfolded again to remove the folding tendency of the carton acting in the folded direction, thereby permitting the carton to hold itself in a square shape. And at the time of reverse folding, the flaps of each carton are expanded so that a contents charging conveyor can be disposed in close proximity to the cartons.

Abstract: This folding packaging case or box of parallelipipedic configuration comprises a bottom, a front panel, a back panel and two lateral panels, and a folding lid, the various panel elements being hingedly interconnected by flexible joints. The bottom comprises at least one joint through which it is hingedly connected to one of the lateral panels, and a peripheral ledge engageable by the peripheral panels so as to lock the peripheral panels in position and thus permit the assembling of the case into a rigid structure.

Abstract: A collapser/collector and strapping apparatus for processing box partitions to place them in condition for shipment. The assembled partitions are collapsed and moved vertically into transversely indexed slots of a collector. From the indexed slots, the partitions are placed into bundles of a preselected number of partitions. The bundles are then delivered to a strapping section where straps are applied to hold each bundle together for further processing.

Abstract: The present invention provides a method and an apparatus for producing a packaging sleeve of polygonal cross-section, particularly adapted to be foldably collapsed, wherein circular or tubular sleeve stock is formed on a stationary spindle or mandrel from a plurality of glued, thin layers of paper, fabric, plastic material or the like, wound or wrapped one over the other. The sleeve is thereafter shaped into a polygonal cross-section. During the shaping of the tubular packaging sleeve while it is in the glue-wetted state, at least one continuous folding edge impressed into the sleeve wall and extending in the longitudinal direction of said sleeve is press-formed at the desired longitudinally extending edge corners of the polygonal cross-section.
