Definitions

  • the invention relates to a blank and a protective angle for a package, and to a method of producing a plate, constituting a blank and an angle from the plate.
  • the delivery of goods requires a packaging to protect the goods, adapted to the products, easy to achieve, economical, and ecological.
  • Some products are transported in cardboard, wood or plastic boxes that can be placed on pallets.
  • This operation often causes damage to the crates at the location of the contact between the crates and the strapping means used, especially at the edges formed by the sides of the crates.
  • This damage is most often characterized by a crushing of the edge located under the strapping means or a general torsion of the body.
  • Another solution is to make corrugated board angles.
  • US 4,212,394 discloses an angle constituted by a corrugated cardboard blank and comprising, when shaped, three faces determining a trihedron.
  • One of the faces serves as a maintenance guide to the other two faces, which present, for one of the battlements, and for the other, merlons leaning perpendicularly against the crenellations.
  • the setting volume of this bracket causes many difficulties of industrial implementation.
  • the flattening can not be obtained industrially, and when it is done manually, it generates many damages especially at the level of the merlons.
  • the document FR 2 673 603 describes an economical solution consisting of a single plate folded and glued on itself so as to form the two wings of the angle, these wings thus comprising a double thickness of cardboard over at least a portion of their width. .
  • a gap is formed between the free edges of the two side flaps folded so as to bring the free edge of one of the flaps in the gap during the final shaping of the element to obtain a blocking dihedral volume.
  • the present invention proposes to overcome these drawbacks by providing a protective angle provided with guiding and locking means in the use position, easy to implement both manually and industrially, and allowing the angle iron to be reused several times.
  • the invention relates to a blank made of cardboard or similar material, delivered flat and intended to be volume for the constitution of an L-shaped protective angle for a package consisting of a single plate having a longitudinal direction, a transverse direction and a given thickness, on which extend a fold line and at least one flap line, longitudinal and parallel, respectively defining two adjacent panels called "external” with reference to the angle bracket volume, and at least one so-called “doubling" panel located at one of the transverse ends of the plate and intended to be folded and fixed on the outer panel which is adjacent to it, in which at least one oblong slot is disposed in overlap on a section of the bending line, and at least one doubling panel has a free longitudinal edge crenellated and provided with a number of so-called "main” slots such that the doubling panel has as many main merlon as lights, each main merlon being arranged for substantially covering a lumen when the blank is flat and the doubling panel is folded and attached to the outer panel adjacent thereto.
  • the invention also relates to a method of forming the preceding blank, comprising the steps of folding on itself a plate obtained by the above method, by folding the panel (s) of the doubling against the panel external adjacent along the flap lines and (s) maintain in this position by fastening means.
  • the invention also relates to a method of constituting an angle from the previous blank comprising the steps of folding the blank on itself along the fold line so that the outer panels are turned towards the outside. outside the L-shape, and each main merlon forcefully inserted into the corresponding oblong slot to lock the angle in the position of use.
  • the blank 10 of Figure 1 is shown flat after cutting a strip or a cardboard plate and has only one thickness e (see Figure 8).
  • a fold line 1 and a flap line 2 extend parallel in the longitudinal direction of the blank 10, thus determining respectively two adjacent panels “external” 4 and 5, and a panel called “dubbing" 6 located at the transverse end of the outer panel 5.
  • the depth p of the main slots is such that when the doubling panel 6 is folded along the flap line 2 on the outer panel 5 adjacent thereto, the merlons substantially overlap the oblong slots 7 ( Figure 2).
  • This operation can be done in the factory using for example hot glue or staples.
  • the stack of several blanks 10 is turned upside down to avoid imbalance of the stack due to the double thickness of cardboard of the panel assembly doubling 6 / outer panel 5 and the simple thickness of cardboard outer panel 4.
  • the inner face of the outer panel 5 and / or the lining panel 6 may be provided with fixing means activated at the time of use by the user such as double-sided transfer tape, adhesive prolonged effect protected by silicone tape, plastic clips or tape.
  • a gap between the edge of the lights 7 and the edge of the merlons 9 has been shown to be relatively large for the sake of clarity in Figure 2, but in reality this space is restricted so that the edges of the merlons and lights are substantially aligned to a few degrees. millimeters. It is the same for Figures 4 and 5.
  • the oblong slots 7 have a width lt substantially equal to the thickness of the plate multiplied by a tolerance factor a in the range of 1.05 to 6, preferably 1.5 to 3.5, typically 2 at 3, and the merlon (s) present (s) a width p substantially equal to the thickness e of the plate multiplied by a tolerance factor ⁇ in a range of 1.05 to 2, preferably of 1.1 to 1.7, typically 1.15 to 1.5, and a length L M less than the length L LUX of the light (s) oblong (s) by a factor of between 0, 5 and 0.99, preferably 0.8 to 0.95, typically 0.85 to 0.90.
  • the width p - of 2 mm in FIG. 1 - merlons was chosen to be equal to the thickness e of the plate multiplied by a factor ⁇ of 1.05; therefore e is 5 mm and was chosen with a factor of 2.63.
  • the oblong slots 7 are arranged in overlap on the fold line 1 so that, on the opposite side to the corresponding merlon 9, they extend only over a width l f substantially equal to the thickness e of the plate.
  • FIGS 3 to 9 show another embodiment of the invention wherein each of the outer panels - 24 a and 24 b of a blank 20 is extended respectively along fold lines 22, 23, by a lining panel 26 a , 26 b adapted to be folded down and held against the outer panels 24 a and 24 b .
  • Five oblong slots 27 are arranged in overlap on a section of the fold line 21.
  • the two doubling panels 26 a, 26 b each having a free longitudinal edge 25 a, 25 b serrated and provided with sufficient slots 28 major, 28b so that they have three main merlons 29, 29b arranged to cover substantially oblong openings 27 a, 27 b when the blank 20 is flat and that the folding panels 26 a, 26 b are folded and fixed to the outer panel 24 a, 24 b adjacent thereto.
  • Both lining panels 26, 26b have merlons 29, 29b.
  • the merlons 29 have a lining panel 26 a are alternately disposed with respect to the merlons 29 b of another lining panel 24 b, the openings 27 a, 27 b being arranged alternately overlapped on the line in such a manner that, on the side opposite the merlon 29 a , 29 b corresponding, they extend only over a width l f substantially equal to the thickness of the plate e .
  • each main slot 28 a, 28 b have a base 30, 30b in which is formed a niche "secondary" 31a, 31b.
  • the second slots 31a and 31b are located opposite the main merlons respectively 29 a and 29 b ( Figure 4).
  • Step (f) may be conducted before or concurrently with steps (a) or (b).
  • step (c) of the method consists in cutting a side slot 31a, 31b in each main slot 28, 28b, the cutout being located substantially on either side of the axis of symmetry of each main slot 28 a , 28 b .
  • Step (d) is a critical step when cutting blanks. Indeed, the manufacturing is mechanized and the rate of cutting and evacuation must be maximum to improve the profitability of the operation.
  • One solution proposed by the invention is to provide that the direction of the grooves is transverse, that is to say that the grooves are perpendicular to the longitudinal edges of the merlons. This stiffens the merlon and reduces the risk of bad cutting.
  • Another solution that can be used alone or in combination with the previous one consists in cutting side slots 31a, 31b in the bottom 30a, 30b of the main slots 28 a, 28 b to provide an upper contact surface the means of evacuation of the cardboard waste and thus to facilitate and improve the evacuation of cardboard waste.
  • step (c) the shape of the side slots 31 a, 31 b cut in step (c) is chosen to allow the application, in step (d) discharge means falls sufficiently large to perform an thrust able to completely evacuate the falls, and so that the evacuation means are not torn off when the process is carried out at high speed.
  • One secondary slot 28, 28b makes it possible to achieve this result, but it can be advantageous to provide a plurality of secondary slots in the bottom of a main slot, particularly when key slots extend over a substantial width.
  • the secondary slots cut in step (c) of the blank manufacturing process may be uniformly distributed with respect to the axis of symmetry of each main slot so that the pushing force applied in step (d) is uniformly distributed. distributed along each main slot.
  • crenellated shape of the cutting line inside the main slots prevents the material close to the edge does bend, thus promoting a clean and precise cutting, effective blocking of the volume blank and an alternation of blocking / unblocking without altering the quality of the blockages as will be explained later.
  • fastening means (32) for example taken from the group consisting of glue, adhesive effect, double-sided tape transfer, staples, plastic clips and tape.
  • the two wings of the angle are thus constituted.
  • Figures 5 to 7 illustrate a method of implementing the blank of Figures 4 and 5 to obtain a protective angle ready for use.
  • the wing 35 has - constituted by the outer panel 24a and the trim panel 26 a - is folded towards the flange 35 b formed by the outer panel 24b and the trim panel 26 b in the direction of the arrows F1.
  • the blank 20 is thus folded upon itself along the fold line 21 so that the outer panels 24 a, 24 b are turned outwardly of the L-shape (Figure 7), and that each merlon main 29, 29b is forcibly inserted into the oblong opening 27a, 27 b corresponding to block the bracket in the use position ( Figure 6).
  • the locking of the angle at an angle d of about 90 ° is obtained by pressing the main merlons against the edge of the lights: when one of the wings is folded towards the other, each merlon crosses the corresponding light being guided by the transverse edges of the latter, and the longitudinal edges of the light pinch the merlon.
  • the direction of the grooves 40 ( Figure 8) is transverse, that is to say that the grooves are perpendicular to the longitudinal edges of the merlons ( Figure 8).
  • Blocking a blank comprising only a crenellated doubling panel may be sufficient, but in some cases it is preferable to provide two crenellated doubling panels ( Figures 3 to 9).
  • a structure according to the invention therefore makes it possible to shape the angle easy, effective and robust, but it also makes it easy to unfold and unblock the angle to put it back flat, store it and reuse it.
