Definitions

  • the present invention relates to a method for producing three-dimensional containers provided with relief decorations.
  • These shopping bags are normally produced from a sheet of preprinted material which is glued and folded to form the bag. Further paper or cardboard pieces can be disposed or glued on particular regions of the sheet, for example that intended to form the base or the upper edge where the handles are attached, to provide greater strength.
  • An object of the invention is to produce a container provided with relief decoration able to increase its visual effect on the consumer.
  • Another object of the invention is to utilize reliefs obtained on deformable material to vary the mechanical properties of the articles formed from said material.
  • Another object of the invention is an automatic production process for such articles starting from materials either in sheet, in punched-out pieces or in rolls which uses traditional machines possibly modified to obtain said reliefs on the articles.
  • a method for producing shopping bags consists of unwinding from a reel 2 a web of papery material having plastic yielding characteristics, in both the transverse and longitudinal direction, of not less than 5%, then subjecting it in a suitable station 6 to the traditional operations of punching, crease-lining, folding and gluing to form a flattened tubular web comprising a plurality of pleats 7 along its longitudinal edges.
  • the tubular web is then fed to a forming unit 8 consisting of a roller 10 comprising on its lateral surface one or more reliefs 12 corresponding to the design to be formed on the shopping bag, and a die 14 facing the roller and made of soft material.
  • a forming unit 8 consisting of a roller 10 comprising on its lateral surface one or more reliefs 12 corresponding to the design to be formed on the shopping bag, and a die 14 facing the roller and made of soft material.
  • the two outer surfaces of the flattened tubular web become provided respectively with a depression 16 and a projecting portion corresponding to the roller motif.
  • the web is then cut in a cutting station 20 to form individual pieces which at one end are subjected to application of the support handles 28 and at the other end are folded to form the bag base 26.
  • the shopping bag obtained in this manner is then fed to a storage station 22 where the bags can be easily stacked on each other by virtue of the co-penetration of the deformations 16, 18 of superimposed bags.
  • the paper web can be advanced stepwise to enable a male/female deformation element to be used, with the male element consisting of a punch producing a positive of the three-dimensional form, or an elastic membrane extended and pressed onto the web and then subjected to an overpressure from the opposite side by a compressed fluid, for example air.
  • a male/female deformation element consisting of a punch producing a positive of the three-dimensional form, or an elastic membrane extended and pressed onto the web and then subjected to an overpressure from the opposite side by a compressed fluid, for example air.
  • the web leaving the roll is subjected, at least in a region which will later form the face of the shopping bag, to a deformation to create the desired motif.
  • the method comprises firstly completing the shopping bag 24 by applying the base 26 and the handles 28, and then subjecting the bag while in the flat configuration to plastic deformation with a deforming element consisting of a punch 30 and a die 32.
  • Figure 5 shows an additional step of the method of producing the shopping bag, which comprises ornamental relief motifs on both the opposing vertical walls.
  • the method consists of firstly making the bag 24 and then inserting it into the cavity 34 of a mould 36 having the same shape and dimensions as the bag when completely unfolded, in which the two walls corresponding to those walls of the bag to be decorated comprise a depression 38 corresponding to the relief motif. Compressed air is then fed into the shopping bag while inserted in the mould, to urge the wall portion of the shopping bag made of yieldable papery material into the mould depression to create the final relief motif 40 in the shopping bag by stretch-moulding.
