Description

BOITE POLYGONALE, ET PLANCHE PREDECOUPEE UTILE POUR LA FABRIQUER POLYGONAL BOX, AND PRE-CUT BOARD USEFUL TO MANUFACTURE
La présente invention concerne l'industrie de l'emballage.The present invention relates to the packaging industry.
Plus précisément, l'invention concerne une boîte polygonale comportant (I) des première, deuxième et troisième faces, (II) une surface apicale comprenant un premier couvercle, et (III) une surface basale comprenant un deuxième couvercle, chacune des première, deuxième et troisième face présentant (a) une première arête commune avec la surface apicale, et (b) une deuxième arête commune avec la surface basale, le premier couvercle étant lié à la première arête commune de la première face, la deuxième face comprenant un premier volet repliable, lié à la première arête commune, ledit premier volet repliable venant s'insérer sous le premier couvercle.More specifically, the invention relates to a polygonal box comprising (I) first, second and third faces, (II) an apical surface comprising a first cover, and (III) a basal surface comprising a second cover, each of the first, second and third face having (a) a first edge common with the apical surface, and (b) a second edge common with the basal surface, the first cover being linked to the first common edge of the first face, the second face comprising a first folding shutter, linked to the first common edge, said first folding shutter being inserted under the first cover.
Des boîtes de ce type sont bien connues de la technique et utilisées avec succès depuis de très nombreuses années. Ces boîtes peuvent être ouvertes et fermées un très grand nombre de fois sans modification apparente de leur aspect, leur assurant ainsi une grande durabilité.Boxes of this type are well known in the art and have been used successfully for many years. These boxes can be opened and closed a very large number of times without any apparent change in their appearance, thus ensuring great durability.
Cependant, en raison même de l'absence de modification apparente de leur aspect, ces boîtes sont vulnérables aux manipulations frauduleuses visant, par exemple à en substituer le contenu en produit originel par d'autres produits indésirables.However, due to the very absence of an apparent change in their appearance, these boxes are vulnerable to fraudulent manipulation aimed, for example, at replacing the original product content with other undesirable products.
Ainsi, un besoin en solutions permettant de détecter une manipulation frauduleuse des produits contenus dans les boîtes tout en permettant de garantir un maintien de possibilités d'ouverture et de fermeture répétées a été ressenti.Thus, a need was felt for solutions allowing fraudulent manipulation of the products contained in the boxes to be detected while making it possible to guarantee that repeated opening and closing possibilities were maintained.
Des techniques visant à détecter une ouverture indésirable sont connues. Par exemple, une solution couramment proposée consiste à apposer un sceau sur le dispositif d'ouverture. Cependant, cette solution est facilement contournée par un manipulateur malveillant, par le repositionnement par collage du sceau arraché ou par l'apposition d'un sceau de remplacement, la production d'un sceau étant généralement peu coûteuse. La présente invention pallie tous ces inconvénients. Ainsi, ladite boîte polygonale est caractérisée en ce que le premier volet repliable comprend une première surface qui présente, sur son périmètre, une première zone ayant une résistance mécanique relativement faible, et en ce que la première surface est appliquée contre, et rendue solidaire du premier couvercle, lorsqu'il est rabattu et rendu coplanaire avec la surface apicale.Techniques for detecting an unwanted opening are known. For example, a commonly proposed solution is to affix a seal to the opening device. However, this solution is easily circumvented by a malicious manipulator, by repositioning by gluing the torn seal or by affixing a replacement seal, the production of a seal being generally inexpensive. The present invention overcomes all these drawbacks. Thus, said polygonal box is characterized in that the first folding flap comprises a first surface which has, on its perimeter, a first zone having a relatively low mechanical resistance, and in that the first surface is applied against, and made integral with the first cover, when folded down and made coplanar with the apical surface.
De ce fait, lorsqu'une une boîte selon l'invention est ouverte par pivotement du premier couvercle autour de l'axe constitué par la première arête commune entre le premier couvercle et la première face, l'ouverture provoque le déchirement du premier volet le long de la première zone ayant une résistance mécanique relativement faible, la première surface restant solidaire du premier couvercle.Therefore, when a box according to the invention is opened by pivoting the first cover around the axis formed by the first common edge between the first cover and the first face, the opening causes the first flap to tear the along the first zone having a relatively low mechanical resistance, the first surface remaining integral with the first cover.
L'intérêt de l'invention réside également dans la grande difficulté à réparer la boîte dans le cas où un manipulateur souhaiterait cacher le fait que la boîte ait été ouverte.The advantage of the invention also lies in the great difficulty in repairing the box in the event that a manipulator wishes to hide the fact that the box has been opened.
Selon un mode de réalisation préféré, le deuxième couvercle peut être relié à la première face par sa deuxième arête commune, et la boîte peut comprendre en outre un deuxième volet repliable, relié à la deuxième face par sa deuxième arête commune. Le deuxième volet repliable peut venir s'insérer sous le deuxième couvercle. De façon préférée, le deuxième volet repliable peut comprendre une deuxième surface qui présente, sur son périmètre, une deuxième zone ayant une résistance mécanique relativement faible, et la deuxième surface est appliquée contre, et rendue solidaire du deuxième couvercle, lorsqu'il est rabattu et rendu coplanaire avec la surface basale.According to a preferred embodiment, the second cover can be connected to the first face by its second common edge, and the box can also comprise a second folding flap, connected to the second face by its second common edge. The second folding flap can be inserted under the second cover. Preferably, the second folding flap may comprise a second surface which has, on its perimeter, a second zone having a relatively low mechanical resistance, and the second surface is applied against, and made integral with the second cover, when it is folded down and made coplanar with the basal surface.
Ainsi, une protection selon l'invention peut également s'appliquer conjointement au dispositif de fermeture de la face basale de la boîte.Thus, protection according to the invention can also be applied jointly to the device for closing the bottom face of the box.
Selon un mode de réalisation préféré, le premier couvercle comprend en outre une première languette repliable qui s'insère sous la troisième face lorsque le premier couvercle est rabattu, la troisième face comprenant une troisième surface qui présente, sur son périmètre, une troisième zone ayant une résistance mécanique relativement faible. La ladite première languette peut alors être appliquée contre, et rendue solidaire de la troisième surface.According to a preferred embodiment, the first cover further comprises a first folding tab which is inserted under the third face when the first cover is folded down, the third face comprising a third surface which has, on its perimeter, a third zone having mechanical resistance relatively small. Said first tab can then be applied against, and made integral with the third surface.
Selon un mode de réalisation préféré, le deuxième couvercle peut comprendre une deuxième languette repliable qui s'insère sous la troisième face. La troisième face peut comprendre une quatrième surface qui présente, sur son périmètre, une quatrième zone ayant une résistance mécanique relativement faible. La deuxième languette peut être appliquée contre, et rendue solidaire de la quatrième surface.According to a preferred embodiment, the second cover may include a second folding tab which is inserted under the third face. The third face may include a fourth surface which has, on its perimeter, a fourth zone having a relatively low mechanical resistance. The second tab can be applied against, and made integral with the fourth surface.
Selon une caractéristique très préférée de l'invention, le matériau constitutif de la boite polygonale est anisotrope.According to a very preferred characteristic of the invention, the material constituting the polygonal box is anisotropic.
L'utilisation d'un matériau anisotrope lors de la fabrication de la boîte permet d'accroître les difficultés rencontrées par un manipulateur malveillant pour masquer l'opération d'ouverture de la boîte. En effet, il a été trouvé que, de façon surprenante, l'utilisation d'un matériau anisotrope conduisait à l'obtention de déchirures avec plus ou moins d'efforts selon l'orientation de l'anisotropie du matériau par rapport à la première zone présentant une résistance mécanique relativement plus faible.The use of an anisotropic material during the manufacture of the box makes it possible to increase the difficulties encountered by a malicious manipulator to mask the operation of opening the box. Indeed, it has been found that, surprisingly, the use of an anisotropic material leads to obtaining tears with more or less effort depending on the orientation of the anisotropy of the material relative to the first area with relatively lower mechanical strength.
De façon préférée, le matériau anisotrope peut présenter une résistance à la traction relativement accrue selon un axe parallèle à une arête choisie parmi les première et deuxième arêtes communes.Preferably, the anisotropic material may have a relatively increased tensile strength along an axis parallel to an edge chosen from the first and second common edges.
Dans ce cas, le matériau anisotrope peut être considéré comme comportant une succession ininterrompue de zones parallèles présentant une résistance mécanique relativement faible. La génération de déchirures sur, par exemple le premier rabat, peut alors se produire avec une probabilité non négligeable sur une zone autre que la première zone de résistance mécanique relativement plus faible.In this case, the anisotropic material can be considered as comprising an uninterrupted succession of parallel zones having a relatively low mechanical resistance. The generation of tears on, for example the first flap, can then occur with a significant probability on an area other than the first area of relatively lower mechanical strength.
L'intérêt d'un tel matériau pour cette application est double : - Lors de l'ouverture d'un échantillon de boîtes présentant cette caractéristique, une proportion très forte de boîtes peut comporter des déchirures à des endroits différents du premier rabat, rendant plus difficile une normalisation des opérations de camouflage de l'ouverture. En raison de la possibilité de déchirage à des endroits différents de la première zone de résistance mécanique relativement plus faible, il peut être envisagé de s'affranchir de la génération d'une telle première zone de résistance mécanique relativement plus faible. En conséquence, les étapes de fabrication de la boîte s'en trouvent réduites.The advantage of such a material for this application is twofold: - When opening a sample of boxes having this characteristic, a very high proportion of boxes can have tears at different places on the first flap, making it more difficult a standardization of the camouflage operations of the opening. Because of the possibility of tearing at different places in the first zone of relatively weak mechanical strength, it can be envisaged to dispense with the generation of such a first zone of relatively weak mechanical resistance. Consequently, the steps for manufacturing the box are reduced.
De façon préférée, la résistance à la traction relativement accrue du matériau anisotrope peut être obtenue par l'incorporation de fibres textiles orientées.Preferably, the relatively increased tensile strength of the anisotropic material can be obtained by the incorporation of oriented textile fibers.

La présente invention concerne également une planche prédécoupée, pliable, utile pour la fabrication d'une boite polygonale.The present invention also relates to a pre-cut, foldable board, useful for the manufacture of a polygonal box.
La présente invention est illustrée ci-après par un exemple non limitatif dans lequel :The present invention is illustrated below by a nonlimiting example in which:
- La figure 1 représente une vue en perspective d'une boîte conforme à un mode de réalisation préféré de l'invention ;- Figure 1 shows a perspective view of a box according to a preferred embodiment of the invention;
- La figure 2 représente une planche prédécoupée, utile pour la fabrication d'une boîte représentée en figure 1. Elle correspond bien entendu à l'aspect qu'a cette boite lorsqu'elle est dépliée.- Figure 2 shows a pre-cut board, useful for the manufacture of a box shown in Figure 1. It of course corresponds to the appearance of this box when unfolded.
Sur la figure 1 est présentée une boîte polygonale 1. Cette dernière comporte (I) des première, deuxième et troisième faces notées respectivement 2, 3, 4, (II) une surface apicale 5, comprenant un premier couvercle 6, et (III) une surface basale 7, comprenant un deuxième couvercle 8.In FIG. 1 is presented a polygonal box 1. The latter comprises (I) first, second and third faces noted respectively 2, 3, 4, (II) an apical surface 5, comprising a first cover 6, and (III) a basal surface 7, comprising a second cover 8.
Chacune des première, deuxième et troisième faces 2, 3, 4 présente (a) une première arête commune, respectivement 9, 10, 11 avec la surface apicale 5, et (b) une deuxième arête commune respectivement 12, 13, 14 avec la surface basale 7. Le premier couvercle 6 est lié à la première arête commune 9 de la première face 2. La deuxième face 3 comprend un premier volet repliable 15, lié à la première arête commune 10. Le premier volet repliable 15 vient s'insérer sous le premier couvercle 6.Each of the first, second and third faces 2, 3, 4 has (a) a first common edge, respectively 9, 10, 11 with the apical surface 5, and (b) a second common edge respectively 12, 13, 14 with the basal surface 7. The first cover 6 is linked to the first common edge 9 of the first face 2. The second face 3 comprises a first foldable flap 15, linked to the first common edge 10.

This first surface 16 comprises, on its perimeter, a first zone 17 having a relatively low mechanical resistance.
La résistance relativement faible de la première zone 17 est obtenue par piquage ou découpage partiel le long du périmètre de la surface 16. Un autre moyen de produire une telle zone de résistance moindre peut consister en la diminution de l'épaisseur du matériau constitutif de la boîte, ou encore en une combinaison de tous ces moyens. Lorsque le premier couvercle 6 est rabattu et rendu coplanaire avec la surface apicale 5, la première surface 16 est appliquée contre, et rendue solidaire du premier couvercle 6. La solidarisation entre la première surface 16 et le premier couvercle 6 peut être obtenue au moyen d'une colle appropriée ou d'une soudure dans le cas ou le soudage du matériau constitutif de la boîte est possible, par exemple lorsqu'il s'agit de certaines matières plastiques.The relatively low resistance of the first zone 17 is obtained by stitching or partial cutting along the perimeter of the surface 16. Another means of producing such a zone of lower resistance may consist in reducing the thickness of the material constituting the box, or in a combination of all these means. When the first cover 6 is folded down and made coplanar with the apical surface 5, the first surface 16 is pressed against, and made integral with the first cover 6. The connection between the first surface 16 and the first cover 6 can be obtained by means of 'A suitable glue or a weld in the case where the welding of the material of the box is possible, for example when it comes to certain plastics.

La figure 2 représente une planche prédécoupée 34, utile pour la fabrication d'une boîte telle que décrite à la figure 1. La planche prédécoupée 34 comporte des première, deuxième, troisième et quatrième faces, respectivement 2, 3, 4, 27, séparées par des pliures 37 à 39. Une languette latérale 35 est solidaire de la première face 2 et en est séparée par une pliure 36 parallèle aux pliures 37 à 39. La première face 2 comporte également des pliures 40, 41 perpendiculaires aux pliures 36 et 37. La première face est ainsi représentée par un parallélépipède rectangle délimité par des arêtes qui sont les pliures 36, 37 et 40, 41.FIG. 2 represents a precut board 34, useful for the manufacture of a box as described in FIG. 1. The precut board 34 has first, second, third and fourth faces, respectively 2, 3, 4, 27, separated by folds 37 to 39. A lateral tongue 35 is integral with the first face 2 and is separated from it by a fold 36 parallel to the folds 37 to 39. The first face 2 also includes folds 40, 41 perpendicular to the folds 36 and 37. The first face is thus represented by a rectangular parallelepiped delimited by edges which are the folds 36, 37 and 40, 41.
Un premier couvercle 6 est solidaire de la première face 2 et en est séparé par la pliure 40. De même, un deuxième couvercle 8 est solidaire de la première face 2 et en est séparé par la pliure 41.A first cover 6 is secured to the first face 2 and is separated from it by the fold 40. Likewise, a second cover 8 is secured to the first face 2 and is separated from it by the fold 41.
Des première et deuxième languettes 21, 24 repliables sont séparées respectivement des premier et deuxièmes couvercles 6, 8 par des pliures 42 et 43. Ces pliures 42 et 43 sont parallèles aux pliures 40 et 41.First and second foldable tongues 21, 24 are separated respectively from the first and second covers 6, 8 by folds 42 and 43. These folds 42 and 43 are parallel to the folds 40 and 41.
Des premier et deuxième volets repliables 15, 18 sont solidaires et séparés de la deuxième face 3 par des pliures 44, 45 parallèles aux pliures 40 et 41.First and second foldable flaps 15, 18 are integral with and separated from the second face 3 by folds 44, 45 parallel to the folds 40 and 41.
Le premier volet repliable 15 comprend une première surface 16 qui présente, sur son périmètre, une première zone 17 ayant une résistance mécanique relativement faible. La première zone 17 correspond ici à un piquage ou une découpe.The first folding flap 15 comprises a first surface 16 which has, on its perimeter, a first zone 17 having a relatively low mechanical resistance. The first zone 17 here corresponds to a stitching or a cutting.
De même, le deuxième volet repliable 18 comprend une deuxième surface 19 qui présente, sur son périmètre, une deuxième zone 20 ayant une résistance mécanique relativement faible.Likewise, the second folding flap 18 comprises a second surface 19 which has, on its perimeter, a second zone 20 having a relatively low mechanical resistance.
La troisième face 4 comporte des troisième et quatrième surfaces 22, 25 qui présentent, sur leur périmètre, des troisième et quatrième zones, respectivement 23, 26 ayant une résistance mécanique relativement faible. Les troisième et quatrième zones 23, 26 correspondent ici à un piquage ou une découpe.The third face 4 has third and fourth surfaces 22, 25 which have, on their perimeter, third and fourth zones, respectively 23, 26 having a relatively low mechanical resistance. The third and fourth zones 23, 26 here correspond to a stitching or a cutting.
Des troisième et quatrième volets repliables 28, 29 sont solidaires et séparés de la quatrième face 27 par des pliures 46, 47 colinéaires aux pliures 44 et 45. Le troisième volet repliable 28 comprend une cinquième surface 30 qui présente, sur son périmètre, une cinquième zone 31 ayant une résistance mécanique relativement faible. La cinquième zone 31 correspond ici à un piquage ou une découpe.Third and fourth foldable flaps 28, 29 are integral with and separated from the fourth face 27 by folds 46, 47 collinear with folds 44 and 45. The third folding flap 28 comprises a fifth surface 30 which has, on its perimeter, a fifth zone 31 having a relatively low mechanical resistance. The fifth zone 31 here corresponds to a stitching or a cutting.
De même, le quatrième volet repliable 29 comprend une sixième surface 32 qui présente, sur son périmètre, une sixième zone 33 ayant une résistance mécanique relativement faible, se présentant sous la forme d'une découpe.Likewise, the fourth folding flap 29 comprises a sixth surface 32 which has, on its perimeter, a sixth zone 33 having a relatively low mechanical resistance, being in the form of a cutout.
Le matériau constitutif de la planche prédécoupée 34 est anisotrope. L'anisotropie est représentée par la double flèche 48 qui indique l'axe dans lequel le matériau présente une plus grande résistance à la traction, relativement à une direction perpendiculaire. La double flèche 48 est orientée parallèlement aux pliures 40 à 47.The material of the pre-cut board 34 is anisotropic. The anisotropy is represented by the double arrow 48 which indicates the axis in which the material has a greater tensile strength, relative to a perpendicular direction. The double arrow 48 is oriented parallel to the folds 40 to 47.
Dans le cas présent, l'axe d'anisotropie, représenté par la double flèche 48, est également parallèle aux première, deuxième, cinquième et sixième zones, respectivement 17, 20, 31 et 33. Cela présente l'avantage de faciliter le détachement de ces dernières lorsqu'elles sont soumises à des contraintes, tout en limitant le risque d'un déchirement en dehors de ces zones.In the present case, the anisotropy axis, represented by the double arrow 48, is also parallel to the first, second, fifth and sixth zones, respectively 17, 20, 31 and 33. This has the advantage of facilitating detachment of the latter when they are subjected to stresses, while limiting the risk of tearing outside these zones.
Selon un mode de réalisation non représenté, l'axe d'anisotropie peut présenter de légères variations angulaires sans modifier significativement les propriétés du matériau. Ainsi, une déviation de quelques degrés, par exemple de +/- 10 degrés permet de maintenir des propriétés mécaniques satisfaisantes. Par ailleurs, si on souhaite favoriser le détachement des troisième et quatrième surfaces 22 et 25, il sera utile d'orienter l'axe d'anisotropie parallèlement à au moins une partie des troisième et quatrième zones 23 et 26, ce qui peut contribuer, dans certains cas, à orienter l'axe d'anisotropie perpendiculairement à la position représentée sur la figure 2. According to an embodiment not shown, the anisotropy axis can have slight angular variations without significantly modifying the properties of the material. Thus, a deviation of a few degrees, for example +/- 10 degrees, makes it possible to maintain satisfactory mechanical properties. Furthermore, if it is desired to promote the detachment of the third and fourth surfaces 22 and 25, it will be useful to orient the anisotropy axis parallel to at least part of the third and fourth zones 23 and 26, which can contribute, in some cases, orient the anisotropy axis perpendicular to the position shown in Figure 2.
