Dimensionally variable lid manufacturing method for boxes of different sizes
A recently granted patent (Publication Number: US11833774B2) discloses a dimensionally variable lid manufacturing method and device for creating lids that fit various sizes of boxes. The method involves preparing rectangular lid sheets with scorelines and perforated lines, cutting off portions of the lid sheets along adjustment sides, and forming additional scorelines for bending the lids along different sides of the box openings. The cut-off width of the portions is adjusted based on the box size, ensuring a precise fit for each lid. Additionally, the lid sheets include dimension adjustment areas and reference areas for printing, allowing for customization and identification of the lids.
Furthermore, the patent details a manufacturing device that automates the process by cutting the lid sheets, forming scorelines, and adjusting the cut-off width according to the box size. The device includes cutters, a scoreline roller, and a mechanism for adjusting the cut-off width. It also features a lid sheet conveying system and a cutter moving device for precise cutting along the adjustment sides. The device streamlines the manufacturing process by efficiently producing lids of varying sizes for individual boxes, enhancing productivity and customization in lid production.
