Definitions

  • the present invention relates to a method of 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
  • 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.
  • the introduction of the resin in any form and with little or no expansion avoids any mechanical stress on the preassembled elements which therefore adjust perfectly between them 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) there is provided in step (c) above a resin capable of forming after polymerization a stiffening means of the box.
  • 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 aforementioned elements.
  • a resin R preferably little or not expandable
  • 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. 1a to 1e describe the steps of the process for manufacturing the elements EU2 forming the sides 6 of the box 1 according to the invention.
  • two rollers 20 and 22 are provided from which, on the one hand, bare and continuous strips 24 of the reinforcement 12 are provided, and on the other hand, strips 26 of the covering material. 8.
  • the frame 12 is therefore filled with the covering material 8 as they leave the rollers 20 and 22, this process being carried out without interruption, of course up to the capacity limit of the rollers 20 and 22 respectively.
  • large capacity rollers a continuous manufacturing 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 of the 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 least in part greater than that referenced l of the strip 24 of the frame 12, in order to provide on the strip 26 of the material covering the covering edges 14.
  • the flap is subsequently folded down on the frame 12, as seen in FIG. 1b and as indicated by the arrow 13, the overlapping edges 14 with interposition of the adhesive agent 28.
  • the strips which have just been pre-dressed are sectioned, using blades 15, into segments S of a chosen length Ls.
  • the segment S is folded against a template 30 to preform it appropriately.
  • an EU2 element preformed and pre-dressed individually, has been obtained and supplied, the free ends of which can be butted together to form a frame constituting the outline of the box 1.
  • the sides 6 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, as well as particularly foldable regions to form 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 flat 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 therefore 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.
  • FIG. 3 the step of adjusting and pre-assembling the different elements EU1 is shown. and EU2 between them inside a mold M.
  • a pre-dressed segment S constituting the element EU2 inside the mold M to preform the sides 6 of the box 1.
  • one abuts suitably the free ends of the segment S which form a first contiguous region.
  • a dish 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 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
  • a so-called topping movement represented by the arrow N.
  • This movement is intended to spread the resin R over at least the contiguous regions of the elements EU1 to EU2 formed respectively by the plate P and by the segment S, and preferably spread it 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. During this operation, it is allowed to harden, preferably at room temperature, the resin which polymerizes.
  • the resin R is introduced into the box 1, that is to say between the steps represented in FIGS. 4 and 5, it is possible to place in the dish P and the segment S which respectively constitute the enclosure formed by the bottom 4 and the sides 6 of the box 1, at least one additional pre-dressed dish forming the unitary element EU3, intended to constitute an internal part of the box, for example a support for an object to be presented.
  • 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.
  • box any room in volume, having any function, open or closed, intended or not to receive an object.
  • This box can therefore conventionally receive an object but it can also form a support base on which said object is placed.
