Description

The invention relates to a method for producing a packaging box or

  presentation, typically for luxury goods, a cabinet made by such a method, a blank for the implementation of such a method, and an assembly comprising such a cabinet.

  It is known to produce packaging or presentation boxes of material such as typically cardboard having a certain thickness. Such boxes generally comprise a carcass of the form of the box and a cover sheet to give the box a proper aesthetic. io

  In order to stiffen the box and thus offer a longer life and greater wear resistance, it is known to rigidly associate corners of the carcass brackets also a material such as adhesive kraft or heat sealable. These angles are arranged between the carcass and the decorative sheet.

  Such an embodiment, however, has a disadvantage. Indeed, the angle is placed in overthickness of the corner of the carcass on the outer face thereof. Thus, when the carcass is dressed by a dressing sheet, the angles appear protruding from the carcass and the box does not have a smooth external appearance. The aesthetics of the cabinet is therefore less satisfactory while it is a determining criterion for the packaging or presentation of luxury products.

  In addition, so that the outer face of the cabinet has no part not dressed by the cover sheet, it is provided with side flaps provided to be covered by another part of the dressing sheet on the extreme parts small sides of the carcass. The side flaps thus cover some angles and their thickness is added to that of the angles thus forming an extra thickness more important.

  The invention aims to overcome this disadvantage by proposing a method of producing a packaging or presentation box whose external appearance is substantially smooth. The box thus produced therefore has an aesthetic appropriate to the type of products packaged or presented.

  For this purpose and according to a first aspect, the invention relates to a method for producing a packaging or presentation box, typically for luxury goods, in which: firstly, there is a flank made of material such as typically cardboard having a certain thickness, cut to the desired shape and grooved to form fold lines for volume, secondly a dressing sheet such as typically paper, fabric, leather or imitation leather, plastic material or the like and thirdly angle fixing angles; the flank is shaped to form a carcass in the shape of the box; the corner angles are placed at the desired locations and fixed rigidly to the carcass; and finally, the carcass thus stiffened is coated with the covering sheet; the method using a locally compressible material with regard to the sidewall and comprising an operation consisting in producing on the sidewall or on the carcass hollow cavities having a shape making it possible to accommodate the angles, these reserves being placed at the locations in front of to be occupied by the angles and the angles are placed in these reserves.

  According to one embodiment, additional reserves, particularly those intended to be located on the edges of the short sides of the carcass, are made with a shape that can also accommodate side flaps of the cover sheet and the flaps are placed in these reserves.

  In one embodiment, the reserves have a depth close to the thickness of the angles.

  According to another embodiment, some reserve have a depth close to the thickness of the angles added to that of the flaps.

  Thus, after dressing the carcass, the box has a substantially smooth external appearance, which gives it a particularly satisfactory aesthetic.

  According to a second aspect, the invention relates to a packaging or presentation box, typically for luxury goods, comprising: a casing-shaped casing, made of a locally compressible material such as typically cardboard having a certain thickness, provided with recessed reserves, corner angles fixed rigidly to the carcass at angles thereof and occupying the recessed and shaped reserves, a covering sheet covering the carcass and the angles.

  Such a cabinet can be made by the method described above.

  According to a third aspect, the invention relates to a blank specifically intended for carrying out the method for producing a packaging or presentation box as described above, the blank comprising hollow reserves having a shape enabling to house the angles, these reserves being placed at the places to be occupied by the angles.

  According to a fourth aspect, the invention relates to an assembly comprising a cabinet as described above and a content such as typically a luxury product, especially food or cosmetic.

  Other objects and advantages of the invention will become apparent from the following description, made with reference to the accompanying drawings.

  Figure 1 is a schematic perspective view of a portion of a cabinet according to the invention wherein the angles are represented in transparency.

  Figure 2 is a schematic sectional representation of the box of Figure 1 according to a plane P substantially perpendicular to the elevation direction of the box.

  Figure 3 is an enlargement of the area A of Figure 2.

  Referring to the figures, there is described a box 1 comprising at least one carcass 2, corner angles 3 and a covering sheet 4.

  It will be noted that the thicknesses shown in FIGS. 2 and 3 have been enlarged for the sake of clarity.

  The carcass 2 has substantially the shape of the box. According to the embodiment shown, the carcass 2 is substantially parallelepipedal and has an upper opening 5 giving access to the interior of the cabinet 1. Other shapes by volume can be envisaged. Similarly one can provide a cover (not shown) for the cabinet 1, covering the opening 5. The cover has a shape complementary to that of the carcass and similar characteristics.

  The carcass shown in Figure 1 comprises side walls 6 and a bottom 7. The side walls 6 have an inner face 9 and an outer face 10. For a carcass of rectangular shape in section, there are small sides 14 of the long sides 15.

  The carcass 2 is made of a locally compressible material such as typically cardboard having a certain thickness. Other materials capable of being compressed locally may be envisaged, such as a plastic material. The constituent material of the carcass 2 has a thickness of the order of a few millimeters, in particular of the order of 0.8 to 3 mm. By compressible material is meant a material whose compression is permanent, that is to say that once compressed, the material does not decompress and keeps the thickness that it has conferred compression.

  The carcass 2 has hollow reserves 8, as shown in FIG. 2. These reserves 8 are zones situated at the angles joining the side walls 6. The reserves 8 thus form at least a part of the corners of the carcass 2. At level of the reserves 8, the walls 6 have a thickness s less than that of the rest of the walls. Thus, two adjacent walls 6 have adjacent end portions of which at least two adjacent portions are of lesser thickness.

  The intaglio reserves 8 can be provided on all the corners of the carcases io 2 and over the entire height of the walls 6. They are made on the outer face 10 of these walls 6, as shown in the figures.

  Angled corners 3 are fixed rigidly to the carcass 2 in corners thereof and occupy the hollow reserves 8. These angles have a shape appropriate to the shape of the reserves. Thus an angle bracket 3 comprises two panels 11 and 12 forming between them an angle substantially equal to 90 in the case where the carcass 2 has right angles, as shown in the figures. These angles 3 allow to stiffen the carcass 2 at its corners. They are made of a material adapted to this stiffening, such as adhesive kraft or heat sealable.

  As represented in FIGS. 2 and 3, the reserves 8 have a depth close to the thickness of the angles 3 and an external shape complementary to that of the angles 3, so that the angles 3 are flush with the internal face 9 and / or external 10 of the carcass 2.

  Thus, provision is made for example that the reserves 8 have a depth and the angles 3 a thickness of the order of a fraction of mm, in particular of the order of 0.15 mm.

  The cabinet 1 comprises a covering sheet 4 covering the outer face of the carcass 2, namely the outer faces 10 of the walls 6 and the outer face of the base 7. The covering sheet 4 may also cover at least a portion of the internal walls 9 of the walls 6. The cover sheet 4 is for example a sheet of paper bonded to the carcass 2 by means of an animal glue or a white glue and has an exterior aesthetic suitable for packaging applications or presentation of luxury goods. This cover sheet 4 may have patterns printed on its outer surface to further improve the aesthetics of the box 1. This cover sheet is for example a sheet of paper, card, fabric, leather or imitation leather, plastic material or the like.

  According to the embodiment shown in Figures 2 and 3, the cover sheet 4 comprises side flaps 13 provided to prevent the outer face of the carcass 2 does not have a zone devoid of dressing. These flaps 13 are intended to be covered by another part of the covering sheet 4. The flaps 13 are provided to be associated with the carcass 2 in the end portions of the short sides 14 of the carcass. For this purpose, reserves 16 are provided on the end portions of the short sides 14 made to a depth sufficient to accommodate, in addition to angles 3, the side flaps 13.

  These reserves 16 of the end portions of the short sides 14 have a depth close to the thickness of the side flaps 13 and a complementary external shape of the side flaps 13 so that the side flaps are flush with the face 10 of the carcass 2 and are substantially invisible. once she dressed.

  The lateral flaps 13 may be longer or shorter than the panels of the angles 3. In the case where the flaps are longer, it is expected to make reserves 16 of suitable dimensions and therefore of length substantially equal to that of the flaps 13. From In this way, the reserves 8 and 16 can have a staircase shape seen in section.

  Because the angles 3 are flush with the outer face 10 of the carcass 2 on the long sides 15 and the flaps 13 of the covering sheet 4 are flush with the outer face 10 of the carcass 2 on the short sides 14, the box 1 provided with its covering sheet 4 has a substantially smooth external appearance and the angles and the flaps 13 are substantially invisible behind the cover sheet 4.

  The cabinet 1 may further include internal setting elements or positioning (not shown) to place objects in the cabinet. These internal elements are supported on the bottom 7 between the walls 6 and comprise for example a plastic material frame provided with fingerprints for receiving the packaged or presented objects.

  As indicated above, the cabinet 1 may also include a lid for closing the cabinet. This cover has a structure similar to the carcass 2, that is to say that it is made in the same way with reserves, corner angles and a cover sheet comprising side flaps.

  Such a box allows for an assembly comprising a box 1 as described above and a content such as typically a luxury product, including food or cosmetics. The content is for example received or wedged in the internal elements of wedging or positioning.

  We now describe a method of making a cabinet 1, as described above.

  Firstly, there is a flank of locally compressible material such as typically paperboard having a certain thickness, cut to the desired shape and grooved to form fold lines for the purpose of setting volume.

  Secondly, there is provided a cover sheet 4 such as paper, card, fabric, leather or imitation leather, plastic or the like, and thirdly corner fixing angles 3.

  The flank is conformed to form a casing 2 in the form of casing 1.

  The corner angles 3 are placed at the desired locations and fixed rigidly to the carcass 2. For this purpose, the angles 3 can be fixed to the carcass 2 by heat-sealing or by means of an adhesive.

  The carcass 2 thus stiffened is coated with the covering sheet 4. The covering sheet can be glued by means of an animal glue or a white glue.

  During the steps described above, it is provided an operation of r to realize on the sidewall or on the carcass 2 recesses 8 recessed having a shape to accommodate the angles 3. These reserves 8 are placed at the locations in front of be occupied by the angles 3.

  We can also provide an operation of making on the sidewall or on the carcass 2 hollow reserves 16 having a shape to accommodate, in addition to angles 3, the flaps 13 of the cover sheet 4. These reserves 16 are placed at the places to be occupied by the flaps 13, that is to say for example in the end portions of the short sides 14, as shown in FIGS. 2 and 3.

  The reserves 8 and 16 can be made on the outer face 10 of the sidewall or the carcass 2. According to another embodiment, the reserves are made on the inner face 9 of the sidewall or the carcass 2. Their depth may be close to the width the thickness of the angles 3, and where appropriate close to the thickness of the angles 3 added to that of the flaps 13, and have an outer shape complementary to that of the angles 3, and if appropriate that of the flaps 13. Thus, as indicated above, the box 1 has a substantially smooth outer surface after the dressing of the carcass 2 by the cover sheet 4, which gives a satisfactory aesthetic to the box 1.

  According to a first embodiment, the reserves 8 and 16 are made on the sidewall before its conformation, before, during or after cutting. We then obtain a blank with hollow reserves 8 having a shape to accommodate the angles 3, these reserves 8 being placed at the locations to be occupied by the angles 3. In addition, the blank has reserves 16 for There, the angles 3 and the flaps 13. The reserves 8 and 16 on the sidewall can be made by stamping, for example by means of a cold or hot press.

  According to a second embodiment, the reserves 8 and 16 can be made during the conformation of the blank.

  According to a third embodiment, the reserves 8 and 16 are made on the carcass 2 before dressing the carcass 2 by the covering sheet 4. The reserves 8 and 16 can then be achieved by means of crushing rollers.

  Once the reserves are made, the angles 3 are placed in these reserves 15 8, as indicated above.

  One can also provide a step of placing the flaps 13 of the cover sheet 4 in the reserves 16 provided for this purpose.

  In the case where the box comprises a lid, it can be made by the same method as that described above. i0
