A foldable case and method of making same are disclosed. The foldable case is collapsible between a closed position and an open position without needing to re-fold the sheet of material. The foldable case is made of a sheet of material. The sheet of material has a central portion, opposing first and second portions, and opposing third and fourth portions. First and second portions adjoin a length of respective top and bottom edges of the central portion. Third and fourth portions adjoin a length of respective left and right edges of central portion. A number of folding lines are provided on the sheet of material. The foldable case can be made by folding along the folding lines and adhering first and second portions to the third and fourth portions so as to form a case in the folded configuration.

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.

A package includes board platform having a folded top platform element and bottom platform element made from cardboard material. The top platform element has cutout portions conforming to shapes of a product to be packaged. A folded cardboard product tray element forms an open cavity conforming to the shape of the product and is secured to at least one of the top platform element and the bottom platform element and is disposed therebetween. A paper platform wrapper covers the exterior surfaces of the top platform element and a paper product tray wrapper covers the interior side wall of the open cavity.

A method for checking and correcting the position of a blank (10) that includes closing the folded right-hand and left-hand flaps (17, 18) of the blank, which are positioned one above the other in an overlapping portion, checking the position of the right-hand edge (13) and of the left-hand edge (14), and comparing the position with a predetermined position in order to determine a positional deviation, if the positional deviation exceeds an admissible deviation value, and before the glue sets, fixing of the central flap (19), then holding the upper face of the right-hand flap and of the left-hand flap by a suction cup (21, 23, 24, 26), and correcting the position of the left-hand flap (18) and/or of the right-hand flap (17) by moving the suction cup (21, 23, 24, 26).

A perforation pattern for multivarible adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.

A method and a system for erecting boxes from box templates of different sizes, said method comprising the steps of: adjusting a size of a frame (5; 105) according to a size of a box template (3; 103) which should be erected; wrapping the box template (3; 103) to be erected around the frame (5; 105); and separating the frame (5; 105) from the box template.

The present invention provides a sheet stacking device, a counter-ejector, and a carton former and is provided with: a hopper unit that stacks cardboard boxes; feed rollers that feed a cardboard box to the hopper unit; a first blower device that blows air from above the hopper unit toward the cardboard box fed by the feed rollers; and a second blower device that blows air between the cardboard box stacked in the hopper unit and the cardboard box fed by the feed roller.

A box erecting machine includes a transport mechanism that can move an un-erected box from an entry portion of the box erecting machine to a forward portion of the box erecting machine. The transport mechanism can include pivot arm(s) and clamp(s) for securing and moving the un-erected box. The machine can also include a box erecting assembly that erects the un-erected box. The box erecting assembly can include an opening or unfolding mechanism that opens or unfolds the un-erected box into a generally rectangular tube. The machine can also include a folding mechanism and a closure mechanism for folding and securing the bottom flaps of the box.

Techniques for corrugate and chipboard knocked-down case inspection and manufacturing are described. In an example, a piece of cardboard is cut according to a shape of a knocked-down case, and a first plurality of measurements are made. The piece of cut cardboard is scored to create a plurality of fold-lines, based at least in part on the first plurality of measurements, and a second plurality of measurements are made. A fold-line between a major panel and a minor panel is folded, based at least in part on the second plurality of measurements, and a third plurality of measurements are made. A fold-line of a tab of the piece of cut cardboard is folded, based at least in part on the third plurality of measured distances. The tab is glued to a panel of the piece of cardboard to form a knocked-down case.

A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.
