One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top.

  • Patent number: 5826408
    Abstract: A rotary flap tucker comprising a tube sector having a smaller arc length end, a larger arc length end, a longitudinal edge, and an edge which helically advances generally from the small arc length end to the large arc length end. The tube sector has end plates each with an edge contoured to avoid contact with a carton flap as the flap tucker rotates about its center axis which is aligned with the carton travel direction. The leading edge of a flap entering the flap tucker follows the helical edge of the flap tucker as it rotates without contacting the flap for a majority of the rotation. Rotation brings the flap tucker's longitudinal edge in contact with the flap along a majority of the flap's length. Continued rotation plows the majority of the length of the flap simultaneously, thereby preventing the flap from misaligning on the carton when the flap is closed. The outside surface of the rotating flap tucker runs against the closed flap of the advancing carton, preferably along the carton's center line.

  • Patent number: 5484373
    Abstract: A kit for making boxes from a paper card stock is described. The kit comprises a flat plate having a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. The card stock preferably comes in two sizes for each size box, one for the bottom and one for the top. The card stock used for the top is slightly larger than the stock used for the bottom so that the same spacers may be used for scoring folding lines for both the top and the bottom and, at the same time, providing a mating fit therebetween.

  • Patent number: 4820253
    Abstract: A container blank particularly suitable for carrying liquids formed from a paperboard web fed in from a roll, the upper and lower edges of which are provided with short cut lines along the score lines forming the side panels. The method for obtaining such as blank consists of a set of rectilinear cut lines spaced apart from each other in correspondence of said upper and lower edges executed at the same time as said short cut lines or during a following stage, the lips defined by short cut lines and by score lines parallel to the edges being folded over and brought into contact with the corresponding panels simultaneously with the carrying out of short cut lines or later after the side seaming of the blank; in this way the container can selectively exhibit different types of top and bottom end closures.

  • Patent number: 4548593
    Abstract: The invention provides a process for making a dry powder box with greater geometrical stability and free of pin holes, gaps and the like through which powder may sift. The process uses a carton blank having a bottom closure wherein a pair of relatively large, opposing dust flaps are first folded into the carton tube, in order to define, maintain and stabilize the cross section of the carton. Then, a pair of relatively smaller, opposing major flaps are folded and glued over the open sides of the large dust flaps. This combination of flaps keeps the large flaps from working out of alignment and helps maintain the cross sectional stability of the box. The top of the carton may be a gable having panels at the ends of the gables which are slightly larger than the cross section, of the gable roof sides. When the gable is formed, the larger ends are pushed down to create a leverage which closes the top opening more securely. The cut lines which form and define the flaps extend across approximately 80.degree.
