Definitions

  • the present invention relates to a method for manufacturing a box, intended in particular for packaging and / or presenting objects.
  • a box the sides of which, respectively forming sides and at least one bottom, are coated with a covering material, such as for example leather or fabric, having the appearance of a quality material.
  • a covering material such as for example leather or fabric
  • the invention relates to a so-called luxury packaging and / or presentation box, in particular obtained by this method.
  • the conventional method of manufacturing boxes covered with a covering material constituted for example by leather, fabric or by a similar material having the appearance consists in carrying out, by a thermoplastic injection technique, a shell whose shape already corresponds to the finished configuration of the box, this shell then being covered with the covering material.
  • thermofluidifiable material during injection risks causing expansion of the covering material, or even deterioration of the latter. This process therefore limits the choice of covering materials to compatible, very specific materials.
  • the present invention aims to remedy these drawbacks by providing a method of manufacturing a packaging box and / or presentation of objects allowing, on the one hand, to considerably reduce the production costs, and on the other hand, to ensure the realization of boxes with a minimum of defects, that is to say meeting the criteria of high quality.
  • preassembled elements which can be finished or semi-finished, such as pre-dressed or plated
  • pre-dressed or plated it is possible to implement automated methods producing these elements in strips and plates in large numbers and at great speed.
  • these elements can be pre-dressed, that is to say worked or semi-worked and then assembled to form the box, they can be made in different materials, or even in materials of the same nature but of different colors or of appreciably different aspects. It is thus possible to obtain boxes meeting the "luxury" criterion, or comprising a fancy aspect which conforms particularly well to the search for exclusivity.
  • the introduction of the resin in any form and with little or no expansion makes it possible to avoid any mechanical stress on the preassembled elements which therefore fit perfectly together without offset or deviation from their contiguous edges.
  • the coating or coating of the resin inside the box by rotation of the mold, ensures perfect covering of the inside face of the box, which gives it, after hardening, excellent solidity. Thanks to this resin which forms an assembly means, it is therefore possible to assemble elements having a very small thickness.
  • step (c) mentioned above a resin capable of forming, after polymerization, is provided to stiffen the box.
  • the present invention also relates to a packaging box and / or presentation of objects, comprising panels respectively forming sides and at least one bottom, at least some of these panels may be externally finished or semi- finished, this box being characterized in that it consists at least in part of pre-assemblable elements, capable of being developed and to be produced in an automated manner, these elements being associated with each other to reconstitute the three-dimensional or elevated shape of the box via a resin may or may not expand, internally coated on at least the contiguous regions of the elements, this resin forming a means of assembling the elements together.
  • the box 1 comprises sections 2 respectively forming at least one bottom 4 and sides 6, only one of which is shown here.
  • the panels 2 are coated with a covering material 8, such as for example leather or fabric, or a natural or synthetic material having the appearance of a high quality material.
  • these sections 2 could include a veneer, for example wood, or an external coating giving the box a finished aesthetic appearance.
  • these sections are formed by elements respectively EU1, EU2 and EU3 shaped into modular elements capable of being preassembled before their final connection.
  • the element EU3 forms a support means which defines a cavity C intended to receive an object to be presented.
  • a cover which is not shown here and which can be advantageously obtained by the method according to the invention, can be adapted on the box 1 to come at least partially cover the elements respectively EU2 and EU3.
  • the element EU1 has a frame 10, while the elements EU2 and EU3 have a similar or identical frame referenced 12.
  • the frame 10 is made of a rigid or semi-rigid material
  • the frame 12 is made of a preferably semi-rigid material, particularly suitable for being folded.
  • the frames 10 and 12 are made of cardboard.
  • the different elements EU1 to EU3 are individually dressed with covering material 8 which can pre-dress the frames 10 and 12 respectively before the assembly of the unitary elements EU1 to EU3.
  • These unit elements are shaped and are assembled together so that they can be developed and therefore produced by automated operations.
  • the elements EU1 to EU3 are therefore associated with one another by means of a resin R, preferably little or not expandable, which internally coats at least the contiguous regions of the above-mentioned elements.
  • the assembly of these elements EU1 to EU3 with one another and their connection by the resin R makes it possible to reconstitute the three-dimensional or elevated shape of the box 1 by simple and inexpensive operations, since they are largely easily achievable by machines of classic production.
  • the elements EU1 to EU3 are joined against each other by means of covering edges 14.
  • the covering edges 14 of the unitary element EU2 which forms the sides 6 of the box 1 are plated and glued to the corresponding reinforcement 12, while the edge 14 of the bottom 4 is left free and rises in a direction substantially parallel to that of the associated sides 6.
  • the two edges 14 respectively of the bottom 4 and of the side 6 shown are applied against each other to form a contiguous region and form a sealing means intended to prevent the exit of the resin R outside of the box 1.
  • the overlapping edges 14 being pressed one against the other inside the box 1 constitute a re-entrant seal.
  • the resin R is not interposed between the two edges 14 like a conventional adhesive, but that it simultaneously covers the two edges 14 laid bare directly against each other and sandwiched, on the one hand by the frame 12, and on the other hand, by the resin R.
  • the resin R covers at least partially the interior surface of the elements EU1 and EU2.
  • the resin R which is for example a resin of the polyurethane type, covers or coats the entire interior surface of the bottom 4 and the sides 6, in a substantially uniform manner to form a uniformly distributed layer which is particularly suitable for stiffen the box 1.
  • the resin R in addition to its function as a means of assembly between the different elements EU1 to EU3 therefore forms a stiffening means.
  • the elements EU1 and EU2 can be constituted by thin strips, for example by wooden veneer.
  • FIGS. 1 to 1 e describe the steps of the process for manufacturing the elements EU2 forming the sides 6 of the box 1 according to the invention.
  • rollers 20 and 22 are provided from which, on the one hand, bare and continuous strips 24 of the reinforcement 12 are supplied, and on the other hand, strips 26 of the material of covering 8.
  • the frame 12 is therefore filled with covering material 8 as they come out of the rollers 20 and 22, this process being carried out without interruption, of course up to the capacity limit. rollers 20 and 22 respectively. With large capacity rollers, a continuous production process is obtained in large series.
  • this process consists in superimposing, in the same orientation, the two strips 24 respectively of the frame 12 and 26 of the covering material 8, then in applying them continuously one on the other with interposition of an adhesive agent 28.
  • This adhesive agent is applied to one or both strips, for example the strip 26 of the covering material, by means of a conventional adhesive delivery device, not shown.
  • One or both strips 24 and 26 can also be pre-glued.
  • the strip 26 of the covering material 8 is provided so that it has a width L at less in the upper part than that referenced from the strip 24 of the frame 12, in order to provide the covering material 14 with covering edges 14 on the strip 26.
  • the cover 12 is then folded down, as seen in FIG. 1 and as indicated by the arrow 13, the covering edges 14 with interposition of the adhesive agent 28.
  • the segment S is folded against a jig 30 to preform it appropriately.
  • an EU2 element has been obtained and supplied, individually preformed and pre-dressed, the free ends of which can be abutted to form a frame constituting the outline of the box 1.
  • the sides 6 are therefore formed. of the box 1 by making the element EU2 from strips 24 and 26 which advantageously comprise the foldable frame 12.
  • the frame 12 can be made of a composite material comprising semi-rigid regions, thus only particularly foldable regions to constitute the four corners of the box 1.
  • FIGS. 2a to 2e other stages of the manufacturing process according to the invention are shown, representing the production of the element EU1 intended to form the bottom 4 of the box 1 seen in FIG. 6.
  • plates 44 of the rigid or semi-rigid frame 10 are cut by stamping or stamping using a tool 40, from a panel 42 of which half has been shown not cut.
  • the cut dishes 44 are glued by interposition of an adhesive agent 48 on a panel 46 of the covering material 8.
  • a cut is made using a stamping or stamping tool 50 the covering material 8 in dishes 52, leaving overlapping edges 14, as shown in FIG. 2c.
  • the dishes 52 are cut from the covering material 8 (FIG. 2b) and then there is bonded, by interposition of the adhesive agent 48, the precut dishes 44 of the rigid or semi-rigid frame 10 on the precut plates 52 of the covering material 8.
  • the dishes P are thus obtained which are formed of superimposed and glued dishes 52 and 44, these composite dishes P also being individually pre-dressed.
  • the dishes P form unitary elements EU1 intended to constitute the bottom 4, or alternatively, a part of the cover of the box 1, not shown.
  • modular elements were provided intended to form the sides of the box 1, in an at least partially developed form, these elements being able to have at least one side with a finished or semi-finished appearance. finished.
  • segment S constituting the element EU2 inside the mold M to preform the sides 6 of the box 1.
  • segment S are properly butted together which form a first contiguous region.
  • a plate P intended to form the bottom 4 of the box 1 is introduced and adjusted into the enclosure formed by this segment S.
  • the edge of covering 14 of this dish fit inside the preformed box, that is to say cover part of the interior surface of segment S.
  • the surface of the frame 10 is chosen so that it is substantially equal to that inscribed in the segment S.
  • the resin R is introduced in a liquid, viscous or semi-viscous form into the box which is preformed by the two elements EU1 and EU2.
  • the resin R is contained in a reservoir 60, shown here very schematically.
  • the mold M, and therefore the future box 1 is given a so-called coating movement represented by the arrow N.
  • This movement is intended to spread the resin R over at least the joining regions of the elements EU1 to EU2 formed respectively by the plate P and by segment S, and spread it preferably over the major part of the interior faces of the preformed box 1.
  • the mold M is mounted on a plate 62 which has an appropriate movement for causing the resin R to flow where desired.
  • the polymerizing resin is allowed to harden, preferably at room temperature.
  • This dish forming the unitary element EU3 is produced like the dishes forming the bottom 4, but with additional folding steps, not shown.
  • the box 1 is extracted from the mold M. The box is then finished and ready, without the need for touch-ups, to be marketed.
