Definitions

  • the invention concerns a case produced by folding a complex comprising a sheet of thin flexible material and a sheet of thick rigid material, a blank intended for producing such a case, and a method of producing such a blank.
  • This type of closure is complex to produce for a package comprising a rigid layer and does not make it possible to keep it firmly closed.
  • the invention aims to permit the production of a package comprising a layer of flexible material and a rigid layer able to be closed and maintained firmly in the closed state using the rigidity of the rigid layer.
  • the invention concerns a case produced by folding a complex, the said complex comprising a sheet of flexible thin material such as cardboard or plastics material with which there is associated a sheet of rigid thick material such as wood or metal, the said case comprising:
  • the invention concerns a blank intended for producing a case as described above, this blank being produced from a complex comprising a sheet of flexible thin material such as cardboard or plastics material with which there is associated a sheet of rigid thick material such as wood or metal, the said blank comprising:
  • the invention concerns a method of producing a blank as described above, the said method comprising the following steps:
  • FIG. 1 is a plan view of the internal face of a blank according to one embodiment of the invention.
  • FIG. 2 is a perspective view of a case with its closure lug open, issuing from the making up of the blank according to FIG. 1 .
  • a blank 1 is described produced from a complex comprising a sheet of flexible thin material, such as cardboard or plastics material, and a sheet of rigid thick material, such as wood or metal.
  • Flexible thin material means a sheet produced from a material whose nature and thickness make it possible to deform the sheet.
  • Sheet of rigid thick material means a sheet produced from a material whose nature and thickness limit the deformation of the sheet. In particular examples, the thickness of the sheet of flexible material is around a few tens of millimetres and that of the sheet of rigid material is around twice that of the sheet of flexible material.
  • the internal face 3 of the blank 1 is defined as being the face of the blank which will be situated inside the case 2 when the blank is made up, the external face 4 forming the visible face of the case 2 when the latter is formed.
  • the sheet of flexible thin material forms the internal face 3 of the blank 1 and the sheet of rigid material forms the external face 4 .
  • the sheet of flexible thin material forms the internal face 3 of the blank 1 and the sheet of rigid material forms the external face 4 .
  • an external appearance with a particular aesthetic appeal according to the material chosen for the sheet of rigid material.
  • the blank 1 comprises lateral panels, including at least one front panel 5 and one rear panel 6 .
  • a first lateral panel 7 is articulated on the rear panel 6 by a folding line 8 .
  • a second lateral panel 9 is articulated on the rear panel 6 by a folding line 10 .
  • the second lateral panel 9 is articulated on the front panel 5 by a folding line 11 .
  • the set of lateral panels 5 , 6 , 7 and 9 define the body 36 of the case with a cylindrical shape overall, for example substantially parallelepipedal, when the blank 1 is made up. According to other embodiments which are not shown, it is possible to envisage interposing additional lateral panels between the front 5 and rear 6 panels in order to produce cases with different shapes. Moreover, it is possible to provide for at least one lateral panel 5 , 6 , 7 and/or 9 to comprise an opening produced by a cut in the complex.
  • the lateral panels are substantially polygonal, for example rectangular, and the folding lines separating the lateral panels are substantially parallel to each other. It is however possible to provide for the panels to have a trapezoidal shape so as to form a case having an inclined opening.
  • a gluing lug 12 is articulated on the front panel 5 along a folding line 13 substantially parallel to the folding lines 8 , 10 and 11 .
  • An opening/closing panel 14 is adjacent to the rear panel 6 and articulated on this along a folding line 15 substantially perpendicular to the folding lines separating the lateral panels.
  • the opening/closing panel 14 has a substantially rectangular shape where the length of the large side corresponds substantially to the length of the small sides of the lateral panels 7 and 9 .
  • An entering lug 16 is articulated on the opening/closing panel 14 at its end opposite to the folding line 15 .
  • the entering lug 16 can be folded at right angles with respect to the opening/closing panel 14 along a folding line 17 substantially parallel to the folding line 15 .
  • the assembly consisting of opening/closing panel 14 and entering lug 16 form a closure lug intended to close the case 2 when the blank 1 is made up.
  • the folding line 17 comprises, at each of its end parts, a removal of material 18 .
  • These removals of material 18 consist of complete cuts of the complex comprising the sheet of flexible material and the sheet of rigid material.
  • the cuts being produced through each of the sheets of the complex, the edges of the removals of material 18 have a certain rigidity and a certain thickness. They extend along the folding line 17 towards the centre of the closure lug, having dimensions which are small compared with the length of the folding line 17 .
  • the folding line 17 comprises a cut 19 produced solely in the sheet of rigid material.
  • the cut 19 is substantially perpendicular to the folding line 17 and extends partially over the opening/closing panel 14 on the one hand and over the entering lug 16 on the other hand.
  • the cut 19 marks the end of the removal of material 18 .
  • the cut 19 also comprises, on the side of the opening of the closing panel, a wing 20 .
  • This wing 20 produced in the sheet of rigid material, is intended to form a projection substantially perpendicular to the opening/closing panel 14 when the entering lug 16 is folded at right angles with respect to this panel 14 , as depicted in FIG. 2 .
  • the cut 19 stiffens the folding line 17 close to the removals of material 18 . It prevents the removal of material 18 from tearing and “propagating” along the folding line when the case 2 is handled.
  • the entering lug 16 can have rounded edges 21 in order to facilitate its insertion when the closure lug is closed.
  • Lateral lugs 24 and 25 are adjacent to and articulated respectively on opposite edges situated on each side of the rear panel 6 , for example the lateral panels 7 and 9 , through folding lines 26 and 27 .
  • These lateral lugs extend on the same side as the opening/closing panel 14 and have a substantially trapezoidal shape.
  • the folding lines 26 and 27 form the large bases of the trapezia.
  • the lateral lugs 24 and 25 each comprise a step, respectively 28 and 29 .
  • These steps 28 , 29 comprising a part of the sheet of flexible material and a part of the sheet of rigid thick material, are themselves rigid and thick. These rigid steps project towards the front panel 5 when the blank 1 is made up. Their function will be described in relation to the description of the case 2 .
  • the blank 1 comprises a second closure lug 22 articulated on the rear panel 6 through a folding line 23 , on the opposite edge to the folding line 15 of the rear panel 6 .
  • Lateral lugs 30 and 31 are provided on the opposite sides to the folding lines 26 and 27 of the lateral panels 7 and 9 .
  • Folding lines 32 and 33 separate the lateral lugs 30 and 31 from the lateral panels 7 and 9 .
  • These lateral lugs 30 and 31 also comprise rigid steps projecting towards the front panel 5 when the blank 1 is made up.
  • All the folding lines of the blank 1 are produced by cutting the sheet of rigid material solely and tracing lines on the sheet of flexible material. This type of cut is referred to as a “half-way cut”, only one of the two sheets in the complex being cut.
  • the first step of the method consists of producing the complex comprising sheets of flexible thin material, such as cardboard or plastics material, and a sheet of rigid thick material, such as wood or metal or plastic.
  • the sheet of rigid material and the sheet of flexible material are associated by fixing the sheet of rigid material to one of the faces of the sheet of flexible material. This fixing is for example provided by gluing the sheet of rigid material to the sheet of flexible material.
  • the complex is cut so as to form the lateral panels, the closure lug or lugs, the gluing lug and the lateral lugs.
  • the sheet of rigid material is cut along the folding lines and the folding lines are traced on the sheet of flexible material.
  • the blank 1 thus has conferred on it the flexibility necessary for its folding and its making up around the folding lines.
  • the cut 19 can also be made by cutting the sheet of rigid material during this step.
  • the removals of material 18 are then performed by complete cutting of the complex.
  • the case 2 is therefore produced by making up the blank 1 , which is folded along the folding lines. It should be noted that the gluing lug 12 makes it possible to fix the front panel 5 to the lateral panel 7 so as to maintain the volume formed by the folding of the blank 1 .
  • the blank 1 is folded so that the sheet of flexible material forms the internal face 3 of the case and the sheet of rigid material forms its external face 4 .
  • a blank 1 like the one depicted in FIG. 1 forms a case with a substantially parallelepipedal shape comprising a body 36 formed by the lateral panels 5 , 6 , 7 and 9 , two openings, one of which 34 is visible in FIG. 2 , defined by the edges of the lateral panels 5 , 6 , 7 and 9 .
  • the body of the case can comprise an opening produced by a cutting of the complex.
  • the lateral lugs 25 and 24 are folded at right angles with respect to the lateral panels 7 and 9 , so that they partially cover the opening 34 .
  • the rigid steps 28 and 29 of these lugs then project towards the front panel 5 and are situated close to the folding lines 26 and 27 .
  • the folding lug is folded above the opening 34 , so that the opening/closing panel covers this opening when it is wished to close the case 2 .
  • the dimensions of the opening/closing panel are adapted to correspond to those of the opening 34 .
  • the entering lug 16 is folded at right angles with respect to the opening/closing panel 14 .
  • the lug 16 is inserted between the front panel 5 and the lateral lugs 24 and 25 . This insertion is facilitated by rounded edges 21 of the entering lug 16 .
  • the insertion of the entering lug 16 has the effect of making the rigid steps 28 and 29 enter the removals of material 18 .
  • the rigidity and thickness of the sheet of rigid thick material confers on the steps 28 , 29 and on the edges of the removals of material 18 sufficient rigidity and thickness to make it possible to obtain a snapping of the rigid steps 28 , 29 into the removals of material 18 , so that the closure position of the case is firmly maintained and can be defeated only by manual manipulation of the closure lug.
  • the steps 28 , 29 can have a generally trapezoidal shape, the small base being produced on the edge close to the front panel 5 , and a dimension parallel to the folding lines 27 , 26 allowing their insertion in the removals of material 18 without projection.
  • the second opening is closed in a similar fashion by the second closure lug 22 .
  • the cuts 19 project substantially perpendicular to the opening/closing panel 14 when the entering lug 16 is folded at right angles with respect to this panel 14 , so that the folding line 17 is stiffened close to the removals of material 18 in order to prevent any tearing of this folding line 17 , which is subjected to stresses when the case 2 is opened or closed.
