BOITE DE CONDITIONNEMENT ETANCHE, NOTAMM ENT POUR UN SEALED PACKAGING BOX, NOTAMM ENT FOR ONE
PRODUIT ALIM ENTAIRE FOODSTUFF
Domaine technique : Technical area :
L' invention concerne une boîte de conditionnement étanche, notamment destinée au conditionnement d'un produit alimentaire, cette boîte de conditionnement comportant un corps de boîte tubulaire réalisé avec un matériau ayant des propriétés d'étanchéité et de thermoscellage. un fond, un opercule d'étanchéité et un couvercle de fermeture, au moins le fond et ledit opercule étant assemblés audit corps de boîte de manière à rendre la boîte de conditionnement étanche aux gaz et à l'humidité. The invention relates to a sealed packaging box, especially for the packaging of a food product, this packaging box comprising a tubular box body made of a material having sealing and heat sealing properties. a bottom, a sealing cap and a closure lid, at least the bottom and said cap being assembled to said can body so as to make the packaging box gas-tight and moisture-proof.
Technique antérieure : Le brevet européen EP 668 151 B l décrit un emballage tubulaire à base de carton comprenant un corps tubulaire réalisé en un matériau complexé, un fond et un couvercle de fermeture, ainsi qu'un opercule d'étanchéité disposé entre le produit contenu dans la boîte de conditionnement et le couvercle, pour assurer de façon satisfaisante l'étanchéité primaire de la boîte de conditionnement. A cet effet, le fond et l'opercule sont assemblés audit corps de manière à rendre la boîte étanche. Le fond peut être fait avec le même matériau complexé que le corps tubulaire. Dans ce type de boîte, après la première ouverture, l'etanchéité secondaire de la boîte n'est assurée que par le couvercle et reste insuffisante dans la plupart des cas. Le couvercle est souvent rattaché au corps de boîte par une zone d'absence de ligne de prédécoupe comme dans les publications US 2.1 52.400 et EP 0 61 1 703. PRIOR ART European Patent EP 668 151 B1 discloses a tubular package based on cardboard comprising a tubular body made of a complexed material, a bottom and a closure cap, and a sealing cap disposed between the product contained in the packaging box and the lid, to satisfactorily ensure the primary seal of the packaging box. For this purpose, the bottom and the cover are assembled to said body so as to make the box tight. The bottom may be made of the same complexed material as the tubular body. In this type of box, after the first opening, the secondary seal of the box is provided only by the cover and remains insufficient in most cases. The cover is often attached to the can body by a zone of absence of precut line as in the publications US 2.1 52.400 and EP 0 61 1 703.
II existe d'autres boîtes de conditionnement proches de ce type d'emballage, notamment des boîtes utilisées pour le conditionnement du tabac, ces boîtes étant constituées d'un corps tubulaire. d'un opercule en aluminium thermoscellé au corps de boîte et d'un couvercle rapporté. L'opercule est conçu pour assurer de façon satisfaisante l'étanchéité primaire de la boîte de conditionnement et de ce fait il est scellé à la paroi intérieure de la boîte. L'étanchéité secondaire est assurée par un couvercle rapporté qui est réalisé par injection, thermoformage ou similaire en une matière thermoplastique, par exemple du polypropylène ou tout autre matériau adéquat. Le corps de boîte comporte un rebord et le couvercle de fermeture peut être mis en place de force pour passer par-dessus ce rebord et fermer la boîte en préservant le contenu de l'humidité extérieure tout en limitant les pertes d'arômes du tabac, Les normes environnementales imposent actuellement des taxes appelées par exemple « Eco-Taxes » aux utilisateurs d'emballages. Ces taxes sont augmentées pour des articles qui sont plus difficilement recyclables car constitués de plusieurs éléments dissociés, non directement liés entre eux, qu'il faut donc trier séparément. C'est par exemple le cas de boîtes telles que mentionnées ci-dessus dans lesquelles le corps de boîte d'une part, l'opercule d'étanchéité primaire d'autre part et, le cas échéant, le couvercle de fermeture assurant une étanchéité secondaire sont des pièces séparées et indépendantes à trier séparément. There are other packaging boxes close to this type of packaging, including boxes used for packaging tobacco, these boxes being made of a tubular body. a heat seal aluminum foil seal with a box body and an attached lid. The operculum is designed to ensure satisfactory the primary sealing of the packaging box and thus it is sealed to the inner wall of the box. The secondary seal is provided by an attached lid which is made by injection, thermoforming or the like in a thermoplastic material, for example polypropylene or any other suitable material. The box body has a rim and the closure lid can be force-fitted to pass over this rim and close the box preserving the contents of the external moisture while limiting the loss of aromas tobacco, The environmental standards currently impose taxes called for example "Eco-Taxes" to the users of packaging. These taxes are increased for items that are more difficult to recycle because they consist of several elements dissociated, not directly related to each other, which must therefore be sorted separately. This is for example the case of boxes as mentioned above in which the box body on the one hand, the primary sealing cover on the other hand and, where appropriate, the closure lid ensuring a seal secondary are separate and independent parts to be sorted separately.
11 n'existe actuellement aucune boîte de conditionnement dans laquelle l'opercule d'étanchéité primaire d'une part et le couvercle d'étanchéité secondaire restent tous deux solidaires du corps de boîte après une consommation partielle du produit contenu dans la boîte de conditionnement, ce qui nécessite une refermeture de la boîte pour garantir la préservation de ce produit. La publication DE 20 2005 010315 U 1 décrit une solution d'un container étanche et sécurisé par superposition de deux couvercles dont un premier couvercle lié au corps du container par un premier film charnière et un second couvercle lié au premier couvercle par un second film charnière. Toutefois, cette solution n'est pas transposable à un embal lage en carton et l 'agencement en cascade des deux couvercles liés entre eux n'est pas compatible avec le conditionnement de produits alimentaires. There is currently no packaging box in which the primary seal on the one hand and the secondary seal cover both remain integral with the can body after partial consumption of the product contained in the packaging box, which requires a reclosing of the box to guarantee the preservation of this product. The publication DE 20 2005 010315 U1 describes a solution of a sealed and secured container by superposition of two covers including a first cover connected to the container body by a first hinge film and a second cover connected to the first cover by a second hinge film . However, this solution can not be transposed to a carton and the cascading arrangement of the two Lids bound together is not compatible with food packaging.
L'un des problèmes à résoudre est d'éviter que la liaison de ces éléments avec le corps de boîte ne s'avère gênante pour l'utilisateur après une première ouverture suivie d'une refermeture. One of the problems to be solved is to avoid that the connection of these elements with the box body is inconvenient for the user after a first opening followed by a reclosing.
Un autre problème qui se pose est celui du développement d'outils de fabrication pour permettre de réaliser cette liaison sans pour autant perturber les caractéristiques basiques de la boîte de conditionnement, à savoir les propriétés d'étanchéité tout particulièrement. Another problem that arises is the development of manufacturing tools to enable this connection to be made without disturbing the basic characteristics of the packaging box, namely sealing properties in particular.
Exposé de l'invention : La présente invention vise à pallier l'ensemble des inconvénients relevés en proposant une boîte de conditionnement comprenant les divers composants indispensables pour garantir l'intégrité du produit contenu dans la boîte ainsi qu'une parfaite étanchéité protégeant ce contenu contre l'humidité, aussi bien en ce qui concerne l'étanchéité primaire, c'est-à-dire avant une première ouverture, que l'étanchéité secondaire, c'est-à-dire après une première ouverture, tout en proposant une boîte de conditionnement respectueuse de l'environnement et formant un tout indissociable plus aisé et moins coûteux à trier, permettant ainsi d'éviter des surtaxes pénalisantes pour non respect des normes environnementales actuelles et futures qui seront de plus en plus draconiennes. DISCLOSURE OF THE INVENTION The present invention aims to overcome all the drawbacks identified by proposing a packaging box comprising the various components necessary to guarantee the integrity of the product contained in the box and a perfect seal protecting this content against humidity, both as regards the primary seal, that is to say before a first opening, the secondary seal, that is to say after a first opening, while proposing a box packaging environmentally friendly and forming a whole inseparable easier and less expensive to sort, thus avoiding penalizing surcharges for non-compliance with current and future environmental standards that will be increasingly draconian.

Illustrations de l'invention et meilleure manière de la réaliser: Illustrations of the invention and best way to achieve it:
En référence aux figures, la boîte 10 comporte un corps de boîte 1 1 tubulaire, en l'occurrence cylindrique, qui est fermé des deux cotés, respectivement par un fond 12 et un couvercle 13. La section circulaire du corps de boîte représentée n'est bien entendu pas limitative et s'étend à toute autre section utilisée dans les boîtes de conditionnement telle qu'une section triangulaire, carrée, rectangulaire, ovoïde, polygonale. Le couvercle 1 3 comporte un rebord de préhension 13a constitué d'un bourrelet destiné à faciliter l'ouverture de la boîte 10. Dans l'état fermé de la boîte 1 0. représentée par les figures 1 A et 3A, le couvercle 1 3 est partiellement encastré dans le haut du corps de boîte 1 1 et délimité du corps de boîte 1 1 par une prédécoupe 15 facilitant son ouverture. Les figures ΓΒ et 3B représentent la boîte 1 0 partiellement ouverte, le couvercle 13 ayant été basculé autour d'une articulation ou charnière 13b qui le relie de façon permanente au corps de boîte 1 1 . Le rebord de préhension 1 3a est pourvu d'ergots 13c (figure 1 C) issus de la prédécoupe 1 5 et garantissant l'inviolabilité de la boîte 10. A ce stade, la boîte 10 est encore fermée par un opercule 14 qui est soudé intérieurement à la paroi intérieure du corps de boîte 1 1 . Cet opercule 14 est étanche et avantageusement découpé dans une bande d'un matériau barrière qui peut être constitué d'un feuillard d'aluminium enrobé d'une matière thermoscellable, d'un complexe à base de papier, de feuillard d'aluminium et de matière thermoscellable, ou d'un ou plusieurs films synthétiques combinant les fonctions d'étanchéité et de thermoscellage. Il est soudé à la paroi intérieure du corps de boîte 1 1 qui est avantageusement réalisé à partir d'un matériau complexé semi-rigide en forme de bande, ayant des propriétés d'étanchéité et de thennoscellage. Ce matériau complexé peut être constitué d'un ou de plusieurs couches de carton, recouvertes d'une couche d'une matière étanche et thermoscellable, comme par exemple du poh'éthylène. En fonction des besoins, l'étanchéité de ce matériau complexé peut être améliorée en ajoutant entre le carton et la matière de thermoscellage, une couche barrière additionnelle, comme par exemple un feuillard d'aluminium ou tout autre film synthétique ayant des propriétés d'étanchéité. La bande de matière complexée peut être obtenue soit par co-extrusion, laminage, ou tout autre procédé. Referring to the figures, the box 10 comprises a tubular box body 1 1, in this case cylindrical, which is closed on both sides, respectively by a bottom 12 and a cover 13. The circular section of the box body shown n ' is of course not limiting and extends to any other section used in the packaging boxes such as a triangular section, square, rectangular, ovoid, polygonal. The lid 1 3 comprises a gripping flange 13a consisting of a bead intended to facilitate the opening of the box 10. In the closed state of the box 1 0. shown in Figures 1 A and 3A, the lid 1 3 is partially embedded in the top of the box body 1 1 and delimited the box body 1 1 by a pre-cut 15 facilitating its opening. Figures ΓΒ and 3B show the box 10 partially open, the lid 13 having been tilted about a hinge or hinge 13b which permanently connects it to the box body 1 1. The gripping flange 1 3a is provided with lugs 13c (FIG. 1C) issuing from the pre-cut 1 5 and guaranteeing the inviolability of the box 10. At this stage, the box 10 is still closed by a cover 14 which is welded internally to the inner wall of the can body 1 1. This cap 14 is sealed and advantageously cut into a strip of a barrier material which may consist of a coated aluminum foil with a sealable material, a paper-based complex, aluminum foil and heat-sealable material, or one or more synthetic films combining the sealing and heat-sealing functions. It is welded to the inner wall of the box body 1 1 which is advantageously made from a semi-rigid complex material strip-shaped, having sealing and heat-sealing properties. This complexed material may consist of one or more layers of cardboard, covered with a layer of a waterproof and heat-sealable material, such as for example poh'éthylène. Depending on the requirements, the tightness of this complexed material can be improved by adding between the cardboard and the heat-sealing material, an additional barrier layer, such as for example an aluminum strip or any other synthetic film having sealing properties. . The complexed material web may be obtained either by coextrusion, rolling, or any other method.
Les figures 1 D et 3C représentent la boîte 10 entièrement ouverte. On notera que l'opercule 14 reste également attaché au corps de boîte 1 1 par une articulation permanente 14a qui est liée en permanence au corps de boîte 1 1. Pour faciliter l'arrachage de l'opercule 14, ce dernier est équipé d'une languette 14b qui est représentée repliée sur les figures 1 B et 3B et déployée sur les figures 1 D et 3C. Cette construction présente la particularité d'avoir à la fois un couvercle 13 articulé et un opercule 14 articulé, ces deux éléments étant attachés en permanence au corps de boîte 1 1 . même après une première ouverture dite ouverture primaire. De ce fait, la boîte 10 selon l'invention présente une meilleure étanchéité secondaire, l'étanchéité secondaire étant celle qui est réalisée après une ouverture primaire et une première consommation de produits conditionnés dans la boîte. La charnière 1 3b du couvercle 13 et l'articulation 14a de l'opercule 14 sont disposées du même coté du corps de boîte 1 1 et de manière superposée permettant une ouverture totale de la boîte 10 afin d'en prélever facilement le contenu et de vider la boîte de son contenu. Figures 1D and 3C show the box 10 fully open. Note that the cover 14 also remains attached to the box body 1 1 by a permanent joint 14a which is permanently connected to the box body 1 1. To facilitate the tearing of the cover 14, the latter is equipped with a tab 14b which is shown folded in Figures 1B and 3B and deployed in Figures 1D and 3C. This construction has the particularity of having both an articulated lid 13 and an articulated lid 14, these two elements being permanently attached to the box body 11. even after a first opening called primary opening. Therefore, the box 10 according to the invention has a better secondary seal, the secondary seal being that which is performed after a primary opening and a first consumption of packaged products in the box. The hinge 1 3b of the lid 13 and the hinge 14a of the lid 14 are disposed on the same side of the box body 1 1 and superimposed allowing full opening of the box 10 to easily remove the contents and of empty the box of its contents.
En référence plus particulièrement aux figures 4A et 4B, pour faciliter les ouvertures successives de la boîte de conditionnement 10 après une ouverture primaire, l'opercule 14 peut être solidarisé au couvercle 13 par sa languette 14b qui peut s'accrocher autour du rebord de préhension 13a du couvercle 13. En complément ou en remplacement de cet accrochage mécanique, il est possible de prévoir un assemblage par adhérence, notamment par un ou plusieurs points de colle 16 ou similaire disposés sur ou sous le couvercle 13 pour lier l'opercule 14 après son ouverture. Referring more particularly to Figures 4A and 4B, to facilitate successive openings of the conditioning box 10 after a primary opening, the cover 14 can be secured to the cover 13 by its tongue 14b which can hang around the gripping flange 13a of the cover 13. In addition to or in replacement of this mechanical attachment, it is possible to provide an assembly by adhesion, in particular by one or more points of glue 16 or the like placed on or under the cover 13 to bind the cover 14 after its opening.
La figure 2 est une vue à plat de l'opercule 14. Sa découpe est faite de manière à former une languette d'arrachage 14b sur un de ses cotés et une patte 14c disposée à l'opposé pour constituer l'articulation 14a. Cet opercule 14 est de préférence prédécoupé, mais pourrait aussi être découpé après sa mise en place et façonné sur le corps de boîte 1 1 au moment de la fabrication de ladite boîte 10. Le diamètre de l'opercule 14 correspond au diamètre intérieur du corps de boîte 1 1 additionné de la hauteur d'un rebord 14e destiné au scellage de l'opercule 14 à la paroi intérieure du corps de boîte 1 1 . La découpe de la languette d'arrachage 14b prévoit deux petites encoches 14d disposées de part et d'autre qui ont comme fonction de faciliter le décollement progressif du rebord 14e de l'opercule 14 sans le déchirer, ni détruire la face intérieure du corps de boîte 1 1 , comme représenté sur les ligures 5A et 5B. Figure 2 is a flat view of the lid 14. Its cut is made so as to form a pull tab 14b on one of its sides and a tab 14c disposed opposite to form the hinge 14a. This cover 14 is preferably pre-cut, but could also be cut after its introduction and shaped on the box body 1 1 at the time of manufacture of said box 10. The diameter of the cover 14 corresponds to the internal diameter of the body of box 1 1 added with the height of a flange 14e for sealing the cover 14 to the inner wall of the box body 1 1. The cutting of the tear tab 14b provides two small notches 14d arranged on either side which serve to facilitate the progressive separation of the rim 14e of the operculum 14 without tearing it or destroying the inner face of the box body 11, as shown in FIGS. 5A and 5B.
La figure 3 A est une vue en coupe axiale de la boîte 1 0 fermée représentée par la figure 1A. 'fous les éléments sont en place sur le corps de boîte 1 1 , à savoir le fond 12, le couvercle 13 et l'opercule 14. La ligure 3 B est une vue en coupe axiale correspondant à la figure 1 B qui montre le couvercle 1 3 ouvert, basculé autour de sa charnière 13b. La figure 3C est une vue en coupe axiale correspondant à la figure 1D qui montre le couvercle 1 3 ouvert, basculé autour de sa charnière 13b et l'opercule 14 ouvert basculé autour de son articulation 14a avec sa languette d'ouverture 14b déployée. Figure 3A is an axial sectional view of the closed box 10 shown in Figure 1A. 'Mad elements are in place on the box 1 body 1, namely the base 12, the lid 13 and the lid 14. The Ligure B 3 is an axial sectional view corresponding to Figure 1 B which shows the lid 1 3 open, tilted around its hinge 13b. Figure 3C is an axial sectional view corresponding to Figure 1D which shows the lid 1 3 open, tilted around its hinge 13b and the lid 14 open tilted around its hinge 14a with its opening tab 14b deployed.
La figure 3D est une vue de détail agrandie qui illustre la soudure de l'opercule 14 à la paroi intérieure du corps de boîte 1 1. On notera également que le corps de boîte 1 1 est pourvu à sa partie supérieure d'une prédécoupe 15 partielle qui offre à l'utilisateur une ouverture rapide et facile du couvercle 13, lui permettant de replier ledit couvercle 13 autour de sa charnière 13b. Cette prédécoupe 15 partielle s'étend à la périphérie du corps de boîte 1 1 , à la hauteur de la charnière 13b du couvercle 13. et s'arrête de part et d'autre de la charnière 13b pour former ladite charnière. Comme on le voit sur les figures, le rebord de préhension 13a du couvercle 1 3 est formé par l'extrémité correspondante du corps de boîte 1 1 qui est ourlé avec et/ou autour du rebord de la cuvette formant le couvercle 13. La patte 14c prévue sur l'opercule 14 est prise en sandwich entre le rebord du couvercle 13 et la paroi intérieure du corps de boite 1 1 et maintenue liée audit corps de boîte 1 1 par scellage et par le rebord de préhension 1 3a. Dans l 'exemple représenté, les charnières 1 3b du couvercle 1 3 et 14a de l'opercule 14 sont juxtaposées et superposées. Rien entendu, toute autre forme de réalisation est envisageable pour permettre l' ouverture de la boîte de conditionnement 10 sans désolidariser ni le couvercle 13. ni l'opercule 14. FIG. 3D is an enlarged detail view which illustrates the sealing of the cover 14 to the inner wall of the can body 1 1. It will also be noted that the can body 11 is provided at its upper part with a precut 15 partial which offers the user a quick and easy opening of the lid 13, allowing it to fold said lid 13 around its hinge 13b. This partial pre-cut extends at the periphery of the box body 1 1, at the height of the hinge 13b of the cover 13. and stops on either side of the hinge 13b to form said hinge. As seen in the figures, the gripping flange 13a of the cover 1 3 is formed by the corresponding end of the box body 1 1 which is hemmed with and / or around the rim of the bowl forming the lid 13. The leg 14c provided on the cover 14 is sandwiched between the rim of the cover 13 and the inner wall of the box body 1 1 and maintained connected to said box body 1 1 by sealing and the gripping flange 1 3a. In the example shown, the hinges 1 3b of the lid 1 3 and 14a of the lid 14 are juxtaposed and superimposed. Nothing understood, any other embodiment is possible to allow the opening of the packaging box 10 without detaching the lid 13. and the lid 14.
Application industrielle Les boîtes 10 de conditionnement sont réalisés de préférence sur une ligne de fabrication en continu comportant au moins une machine de formage du corps de boîte suivie d'une première machine de fermeture d'une des extrémités du corps de boîte par un opercule et un couvercle. Le fond est ensuite rapporté sur l 'autre extrémité du corps de boîte après remplissage sur une seconde machine de fermeture. Industrial application The packaging boxes 10 are preferably made on a continuous production line comprising at least one forming machine of the can body followed by a first machine for closing one of the ends of the can body by a lid and a lid . The bottom is then attached to the other end of the can body after filling on a second closure machine.
Lors de la fermeture de la boîte avant remplissage, on cherche à positionner précisément les moyens de liaison de l'opercule 14 et du couvercle 13 par rapport au corps de boîte pour garantir la superposition de la charnière 13b du couvercle 13 et de l'articulation 14a de l'opercule 14, ceci afin d'obtenir une boîte 10 qui s'ouvre totalement pour pouvoir la vider aisément de son contenu, notamment lorsqu'il s'agit de produits alimentaires en pièces tels que des chips, bouchées, flocons, etc. Si la charnière 13b prévue pour le couvercle 13 est réalisée sur la même machine que celle qui réalise l'articulation 14a de l'opercule 14, l'orientation et le positionnement de ces moyens de liaison 13b, 14a sont parfaitement maîtrisés et ne nécessitent pas de système d'indexage spécifique. A l'inverse, si la charnière 13b du couvercle 1 3 est réalisée sur une autre machine, par exemple la machine de formage du corps de boîte 1 1 , que celle qui réalise l'articulation 14a de l'opercule 14, par exemple la machine de fermeture du corps de boîte 1 1 , alors il faut, lors de l'introduction du corps de boîte 1 1 déjà muni de la charnière 13b, par exemple par l'absence, de la prédécoupe 1 5. orienter le corps de boîte 1 1 de telle façon que cette charnière 13b se superpose à l'articulation 14a de l'opercule 14, qui est toujours réalisée avec la même orientation sur la machine de fermeture du corps de boîte 1 1 . When closing the box before filling, it is sought to precisely position the connecting means of the cover 14 and the cover 13 relative to the box body to ensure the superposition of the hinge 13b of the cover 13 and the joint 14a of the lid 14, this in order to obtain a box 10 which opens completely to be able to empty easily its contents, especially when it comes to food products in pieces such as chips, bites, flakes, etc. If the hinge 13b provided for the cover 13 is made on the same machine as the one that makes the articulation 14a of the cover 14, the orientation and positioning of these connecting means 13b, 14a are perfectly controlled and do not require specific indexing system. Conversely, if the hinge 13b of the cover 1 3 is made on another machine, for example the forming machine of the box body 1 1, that which performs the articulation 14a of the cover 14, for example the closing machine of the box body 1 1, then it is necessary, during the introduction of the box body 1 1 already provided with the hinge 13b, for example by the absence of the precut 1 5. guide the box body 1 1 so that this hinge 13b is superimposed on the hinge 14a of the lid 14, which is always made with the same orientation on the box body closing machine 1 1.
De même, si l'articulation 14a de l 'opercule 14 est réalisée sur une autre machine que la machine de fermeture du corps de boîte 1 1 , alors il faut également, lors de Γ introduction de l'opercule 14 dans le corps de boîte 1 1 , orienter l'opercule 14 de telle façon que son articulation 14a se superpose à la charnière 13b du couvercle 13. Similarly, if the hinge 14a of the cover 14 is made on a machine other than the closing machine of the can body 1 1, then it is also necessary, when Γ introduction of the cover 14 in the box body 1 1, orient the cover 14 so that its hinge 14a is superimposed on the hinge 13b of the cover 13.
Pour faciliter l'orientation du corps de boîte 1 1 par rapport à l'opercule 14 ou inversement, on repère la charnière 13b du couvercle 13 soit en détectant l'absence de la prédécoupe 15 soit en ajoutant un repère 1 7 mécanique et/ou optique. Ce repère 1 7 peut être formé mécaniquement par déformation ou découpe de matière pour créer un relief, une encoche, une languette ou similaire. Il peut être aussi formé par impression pour créer une marque, un code ou similaire. Ce repère 1 7 peut être identifié par tout procédé de repérage connu tel que par lecture optique au moyen d'une caméra, détection mécanique au moyen d'un doigt palpeur, détection pneumatique par variation de flux, ou similaire. Si le repère 17 est une encoche, on peut l'utiliser comme détiOmpeur avec une forme correspondante sur la machine concernée. Tout autre moyen d'indexage est possible dans le but d'orienter correctement le corps de boîte 1 1 et l'opercule 14 ou inversement en vue de superposer lesdites charnières 13b et 14a. To facilitate the orientation of the box body 1 1 with respect to the lid 14 or vice versa, the hinge 13b of the lid 13 is identified either by detecting the absence of the precut 15 or by adding a mechanical mark 17 and / or optical. This marker 17 may be mechanically formed by deformation or cutting of material to create a relief, a notch, a tongue or the like. It can also be formed by printing to create a mark, a code or the like. This marker 17 can be identified by any known identification method such as by optical reading by means of a camera, mechanical detection by means of a probe finger, pneumatic detection by flow variation, or the like. If the mark 17 is a notch, it can be used as a deflector with a corresponding shape on the machine concerned. Any other indexing means is possible for the purpose of correctly orienting the box body 1 1 and the cover 14 or vice versa in order to superpose said hinges 13b and 14a.
