Description

The present invention relates to the packaging industry.
More particularly, the present invention relates to a polygonal box comprising (I) first, second and third surfaces, (II) a top surface forming a first lid, and (III) a bottom surface forming a second lid. And each of the first, second and third surfaces has (a) a first edge common to the top surface and (b) a second edge common to the bottom surface. The lid of the first surface is connected to a first common edge of the first surface, the second surface includes a first folding flap that connects to the first common edge, the first folding flap being Inserted under the first lid.

  This type of box is well known in the art and has been used successfully for many years. This box can be opened and closed numerous times without its apparent change, thus giving it great durability.

  However, as a result of the fact that there is no visible change in its appearance, this box is subject to deceptive operations that aim, for example, to replace its original contents with other undesirable products.

  Accordingly, there is a recognized need for a solution that allows detection of fraudulent handling of products contained in a box while at the same time ensuring performance with repeated opening and closing.

  Techniques for detecting undesirable opening are known. For example, a commonly proposed solution consists of putting a seal on the opening mechanism. However, a confident vicious person can solve the above problem by applying a peeled seal or by applying a replacement seal, i.e. applying a seal that is generally fairly inexpensive to create. You can easily dodge the law.

  The present invention alleviates all these deficiencies. Thus, in the polygonal box described above, the first folding flap includes a first surface having a first border around which the mechanical strength is relatively low, and the surface is folded and the top. It is characterized by being pressed against and secured to the first lid when coplanar with the surface.

  As a result, the mechanical strength is relatively low when the box of the present invention is opened by rotating the first lid about an axis consisting of a first edge common to the first lid and the first surface. The first flap is torn off by opening along the first boundary, and the first surface is secured to the first lid and remains.

  An advantage of the present invention is that there is a great difficulty in repairing the box when a malicious person tries to hide that the box has been opened.

According to a preferred embodiment, the second lid may be connected to the first surface by its second common edge, and the box is connected to the second surface by the second common edge. Further folding flaps may be included. The second folding flap can be inserted under the second lid. Preferably, the second folding flap may include a second surface having a second border around which the relatively low mechanical strength is present, and the surface is folded and coplanar with the bottom surface. When pressed, it is pressed against and secured to the second lid.

  Therefore, the protection according to the present invention may be applied simultaneously to a device for closing the bottom surface of the box.

  According to a preferred embodiment, the first lid further includes a first folding tab that is inserted below the third surface when it is folded, which third surface has a relatively low mechanical strength. A third surface having a perimeter at its periphery. In this case, the first tab can be pressed against and secured to the third surface.

  According to a preferred embodiment, the second lid may include a second folded tab that is inserted under the third surface. The third surface may include a fourth surface having a fourth boundary around which the mechanical strength is relatively low. The second tab can be pressed against and secured to the fourth surface.

  In accordance with the highly preferred features of the present invention, the material from which the polygonal box is made is anisotropic.

  The use of anisotropic materials when manufacturing the box can increase the difficulty that a confident villain encounters when hiding the operation of opening the box. In fact, the use of anisotropic materials can result in tearing with a greater or lesser degree of force depending on the anisotropic orientation of the material with respect to the first boundary where the mechanical strength is relatively low. I understood.

  Preferably, the anisotropic material may have a relatively high tensile strength along an axis parallel to an edge selected from the first and second common edges.

  In this case, the anisotropic material can be considered to continuously have parallel boundaries with relatively low mechanical strength. For example, tearing may occur on the first flap, and this tearing occurs with a probability that cannot be ignored at boundaries other than the first boundary where the mechanical strength is relatively low.

The benefits from such materials in the present application are double as follows.
-When opening a sample of a box exhibiting this feature, a very large percentage of boxes will tear at sites other than the first flap, making it difficult to standardize the operation of camouflaging the opening.
-Since there is a possibility of tearing other than the first boundary where the mechanical strength is relatively low, it is also conceivable to omit making such a first boundary where the mechanical strength is relatively low. As a result, the steps associated with manufacturing the box are thereby reduced.

  The relatively high tensile strength of the anisotropic material can preferably be obtained by including oriented textile fibers.

The oriented textile fibers are preferably selected from the group consisting of cellulose, viscose, cotton, flax, hemp, nettle, wool, silk, polyester, nylon, polyolefin, aramid.
These textile fibers may be present in the form of woven yarns.

  According to a more preferred embodiment, the polygonal box of the present invention comprises (I) a third folding flap inserted under the first lid and (II) a fourth folding inserted under the second lid. It further includes a fourth surface with a flap.

  A common example of a box that meets this definition would be a rectangular parallelepiped box with four sides, one top surface, and one bottom surface.

  According to a more preferred embodiment, the third folding flap may include a fifth surface having a fifth boundary around its relatively low mechanical strength. When the first lid is folded and coplanar with the top surface, this fifth surface is pressed against and secured to the first lid. The fourth folding flap may include a sixth surface having a sixth boundary around the periphery thereof that has a relatively low mechanical strength. When the second lid is folded and coplanar with the bottom surface, this sixth surface is pressed against and secured to the second lid.

  The polygonal box of the present invention is more preferably still made primarily from cardboard.

  After printing the design on the surface of the cardboard, the cardboard may be coated with a polymer film that gives it protection from moisture. Of course, this polymer film should not have a significant influence on the material properties required here. Acceptable polymer films include polyethylene, polypropylene, polystyrene, halogenated polyolefins such as polyvinyl chloride or polyfluoroethylene.

  The invention also relates to a pre-cut folded sheet that can be used to produce a polygonal box.

The invention is illustrated by the following non-limiting examples:
1 depicts a perspective view of a box according to a preferred embodiment of the invention;
FIG. 2 depicts a precut sheet that can be used to manufacture the box depicted in FIG. This figure, of course, corresponds to the appearance when this box is unfolded.

  FIG. 1 shows a polygon box 1. The polygonal box includes (I) first, second and third surfaces labeled 2, 3, 4 respectively, (II) a top surface 5 containing the first lid 6, and (III) It includes a bottom surface 7 that includes a second lid 8.

  The first, second and third surfaces 2, 3, 4 each have (a) a corresponding first edge 9, 10, 11 in common with the top surface 5, and (b) a corresponding first Two end edges 12, 13, 14 are shared with the bottom surface 7.

  The first lid 6 is connected to the first common edge 9 of the first surface 2. The second face 3 includes a first folding flap 15 that is connected to a first common edge 10. The first folding flap 15 is inserted under the first lid 6. As a special feature, the polygon box 1 has a first surface 16 on a first folding flap 15. The first surface 16 has a first boundary 17 having a relatively low mechanical strength at its periphery.

This relatively low mechanical strength of the first boundary 17 is obtained by piercing or partially cutting along the periphery of the surface 16. Another way of creating such a border with less strength may consist of reducing the thickness of the material from which the box is made, or also all combinations of these methods.

  When the first lid 6 is folded and coplanar with the top surface 5, the first surface 16 is pressed against and secured to the first lid 6. The fixing between the first surface 16 and the first lid 6 can be done by means of a suitable adhesive or if the material from which the box is made is weldable, for example in the case of certain plastics. .

  The second lid 8 is connected to the first surface by its second common edge 12. The second folded flap 18 is connected to the second surface by its second common edge 13.

  The second folding flap 18 is inserted under the second lid 8. The second folding flap 18 includes a second surface 19 that has a second border 20 around it that has a relatively low mechanical strength. The method of creating a boundary having a relatively low mechanical strength at the second boundary 20 can be selected from methods that can be used for the first boundary 17 having a relatively low mechanical strength.

  The second surface 19 is pressed against and secured to the second lid 8 shown here being folded and coplanar with the bottom surface 7. As before, acceptable fixing methods include bonding with adhesives and welding.

  The first lid 6 further includes a first folding tab 21 which is inserted under the third surface 4 when the first lid 6 is folded. The third surface 4 includes a third surface 22, which has a third boundary 23 around its relatively low mechanical strength. The first tab 21 is pressed against and secured to the third surface 22 when the box is closed.

  Similarly, the second lid 8 includes a second folding tab 24 which is inserted under the third face 4. The third surface 4 includes a fourth surface 25, which has a fourth boundary 26 around its relatively low mechanical strength. The second tab 24 is pressed against and secured to the fourth face 25 when the box is closed.

  Polygon box 1 includes a fourth face 27. This face includes (I) a third folding flap 28 inserted under the first lid 6 and (II) a fourth folding flap 29 inserted under the second lid 8.

  The third folding flap 28 includes a fifth surface 30, which has a fifth boundary 31 around it that has a relatively low mechanical strength.

  Although not shown, when the lid 6 is in the closed position, the fifth surface 30 is pressed against the first lid 6 when it is folded and coplanar with the top surface 5. It is fixed.

  The fourth folding flap 29 includes a sixth surface 32, which has a sixth boundary 33 around it that has a relatively low mechanical strength. The sixth surface 32 is pressed against and secured to the second lid 8 which is coplanar with the bottom surface 7.

  The first surface 2 includes lateral tabs 35 that are pressed against and secured to the fourth surface 27.

The polygon box 1 is mainly made from cardboard. That is, cardboard is the primary component of the box, and the box can be combined with an additional layer of insulation such as a paper covering and / or polymer film.

  FIG. 2 depicts a pre-cut sheet 34 that can be used to produce the box shown in FIG.

  The pre-cut sheet 34 includes first, second, third, and fourth surfaces 2, 3, 4, and 27 that are divided by fold lines 37 to 39, respectively. Lateral tabs 35 are secured to the second surface and separated from surface 2 by creases 36 parallel to creases 37-39.

First surface 2 includes folds 40, 41 perpendicular to folds 36 and 37. Therefore, the first surface is represented by a quadrangular parallelepiped with boundaries of the folds 36, 37 and 40, 41 as boundaries.
The first lid 6 is fixed to the first surface 2 and is separated from the surface 2 by a crease 40.

  Similarly, the second lid 8 is fixed to the first surface 2 and is separated from the surface 2 by a crease 41.

  The first and second folding tabs 21 and 24 are separated from the first and second lids 6 and 8 by folds 42 and 43, respectively. These folds 42 and 43 are parallel to the folds 40 and 41.

  The first and second folding flaps 15, 18 are secured to and separated from the second face 3 by folds 44, 45 parallel to the folds 40 and 41.

  The first folding flap 15 includes a first surface 16, which has a first boundary 17 around which the mechanical strength is relatively low. Here, the first boundary 17 corresponds to a fistula or a cut.

  Similarly, the second folding flap 18 includes a second surface 19 that has a second border 20 around it that has a relatively low mechanical strength.

  The fourth surface includes third and fourth surfaces 22, 25, which have third and fourth boundaries 23, 26 around them with relatively low mechanical strength. Here, the third and fourth boundaries 23 and 26 correspond to fistulas or cuts.

  The third and fourth folding flaps 28, 29 are secured to and separated from the fourth surface 27 by folds 46, 47 that are collinear with the folds 44 and 45.

  The third folding flap 28 includes a fifth surface 30, which has a fifth boundary 31 around which the mechanical strength is relatively low. Here, the fifth boundary 31 corresponds to a fistula or a cut.

  Similarly, the fourth folding flap 29 includes a sixth surface 32, which has a sixth boundary 33 in the form of a cut around its periphery, which has a relatively low mechanical strength.

  The material from which the precut sheet 34 is made is anisotropic. This anisotropy is represented by a double-headed arrow 48 indicating the axis, which material has the greatest tensile strength along this axis compared to the vertical direction. The double-headed arrow 48 is parallel to the fold lines 40-47.

  In this case, the anisotropic axis represented by the double-headed arrow 48 is also parallel to the first, second, fifth and sixth boundaries, 17, 20, 31 and 33, respectively. This has the advantage of making them easier to pull apart when stressed and at the same time limiting the risk of tearing outside these boundaries.

  When in accordance with an embodiment not drawn above, the anisotropic axis can show a slight angular change without significantly changing the properties of the material. Thus, it is possible to maintain satisfactory mechanical properties even if the angle is shifted slightly, for example by +/− 10 °. Further, if the third and fourth surfaces 22 and 25 should be pulled apart, it is beneficial to orient the anisotropic axis parallel to at least some of the third and fourth boundaries 23 and 26. However, and in some cases this will serve to orient the anisotropic axis at right angles to the position depicted in FIG.

It is a perspective view of the box of the present invention. It is a figure which shows the precut sheet | seat used in order to manufacture the box of this invention.
