Definitions

  • the present invention relates to a manufacturing process of a box or case as well as the chain of manufacture and the box or the box obtained.
  • French Patent No. 1,251,772 describes the manufacture from such a paper box.
  • This box includes a box body with a cover telescopically mounted on the end of the box body.
  • the manufacturing process for this type of box consists to wind several layers of paper so helical around a longitudinal axis thanks to a shaping mandrel and a winding machine classic.
  • An internal tube is then produced in an external tube then cutouts are made from the outside inward so as to cut out the layers of the outer tube to the inner tube and then from inside to outside so as to cut out the layers of the inner tube outward to outer tube.
  • top and bottom sealing the internal tubes and external forming the box body and the cover may for example be metallic and are of the type known. It allows to obtain the complete closure of the box.
  • Such boxes are easily made of paper because this material lends itself easily to winding helical, especially in thin, but such manufacturing process seems difficult to transpose to the realization of wooden boxes, in material plastic or any other sheet material such as by leather or certain fabrics, in addition to rendering more complex manufacturing.
  • the problem of helical winding is to require a double cut, one outside for the outer tube and the other inner tube for the inner tube, which becomes tricky for wooden boxes, or boxes difficult to cut.
  • wood Another advantage of wood is that it can receive various forms of "printing" so reported, like labels, that made in the mass by direct printing.
  • the process involves gluing sheets of wood on an expandable mandrel.
  • Tubes obtained with different diameters and heights are nested and glued to each other.
  • this process provides for the realization of sections of tubes, independent of each other, which are then assembled.
  • the product obtained is composed of several parts (cover, body, top, bottom) made independently with their own tolerances which moves this process away from solutions to resolve problems to which the present invention overcomes.
  • the purpose of the present invention is to provide a manufacturing process which makes it possible to carry out packaging, especially for luxury products from sheet materials, including wood unrolled or sliced, packaging with no protruding part when the cover is fitted on the body of the box, which has a good mechanical strength, which can be achieved more wide than high or higher than wide indifferently, whose steps can be automated, whose accuracy is very high which leads to an excellent fit of the nesting.
  • the method according to the invention comprises a variant of the main embodiment in which the adjustments of rolled sheets are made on board franc.
  • the invention also relates to the production line of this box which allows to put in implements the main embodiment of the process, this chain comprising an original succession of machines of known type, according to claims 9 and 10.
  • the device allowing the implementation of the variant provides an original arrangement of means known.
  • the invention also relates to the box thus obtained which has a cylindrical shape, but whose profile can vary endlessly and whose accuracy of fitting of the cover on the body is remarkable since they come from the same room.
  • a packaging box especially made of wood for elaborate food products, includes a box body with two coaxial tubes with a bottom as well as a cover with a top and is characterized in that it comprises the steps described in claim 1.
  • the invention also relates to a production line allowing the implementation of the process, this chain being defined in claim 9.
  • the invention also relates to the box made according to the process by means of the production line of the invention, this box characterized by what the cover is telescopic socket relative to the box body and in that the winding is concentric.
  • the box when made of wood includes outer layers of the box body and cover made of noble essence while the layers intermediaries when making boxes multilayers are in essence economical.
  • Figure 1 there is shown schematically the different stages of manufacturing a box according to the invention, these steps being referenced by the letters A to J.
  • Step A is to prepare the material sheets for the subsequent steps.
  • step B the plate 10 intended for manufacturing the first strips is sanded bevel by means of an inclined belt sander 26, likewise the plate 12 is sanded on the opposite side by a inclined belt sander 28.
  • step C the plate 10 is cut to generate several first strips 30, only one of them being shown for the simplification of the diagram.
  • plates 14 and 16 are marked in view of their cutting, these plates 14 and 16 being provided respectively for making tackles 36 from above and 38 from below and bodies 40 and 42 above and below the box.
  • step D there is a first strip 30, bevelled in its part 31, a second strip 32, bevelled in its part 33 and presented inverted, the mention 34 then being shown in broken lines.
  • Step E corresponds to the abutment of the first strip with the second and to the mounting of the bodies above and below the box, on the tackles of the above and below the box.
  • This assembly is generally carried out by simple bonding.
  • step E provision is also made for gluing the first and second strips before the subsequent winding step.
  • the two bands have a width L , and lengths respectively P1 for the first band and P2 for the second band with P2 greater than P1 so as to take account of the increase in diameter during the subsequent winding as it will be described later.
  • the two strips are abutted using an adhesive tape 44, disposed on a height l which determines the exterior height of the box body.
  • the overlap zone ⁇ is located at the end of the first strip and juxtaposed with the abutment zone.
  • the second strip is coated with glue over its entire length P2 and over a height l , as well as over the entire overlap zone located at the free end of this second strip and referenced ⁇ .
  • This glue zone is referenced 46.
  • the winding phase is shown in the figure 1 and the result obtained in FIG. 4.
  • step F the first and second abutting strips are wound on themselves, the first strip 30 then substantially forming a tube with the overlap zone ⁇ , while the second abutting strip is wound so concentric to form a second tube with the overlap zone ⁇ .
  • the part 46 comprising adhesive makes it possible to secure the first and second tubes to one another, always along the length ⁇ .
  • step G it is planned to sand and mill the box body thus obtained, so as to create an upper 52 and lower 54 over-bore, using a milling machine 50, the assembly being sanded using a sander 48.
  • step H the top and bottom of the box can be arranged in the upper and lower part of the box body because the top box body 40 and the bottom box body 42 penetrate inside the second tube and are positioned in abutment on the walls of the first tube thanks to the overbores 52 and 54
  • Top and bottom tackles respectively 36 and 38, come flush with the upper part and lower of the box body and overflow outside.
  • step I Peripheral sanding of these claddings, shown in step I , makes it possible to obtain a box body without any projecting element.
  • Step J is the final step which consists in cutting the box body, only on the thickness of the outer tube along line 56, shown in broken lines in Figures 1 and 5, in order to separate the upper part of the second strip 32 which forms the peripheral wall of the cover, this cover being completed by the box top body 40 and the box top plating 36.
  • the actual body of the box includes the part bottom of the second strip with glue 46 and the first corresponding inner tube when winding the first strip, the cover coming to cap this first tube telescopically.
