Description

La présente invention concerne un dispositif d'emballage et de protection antichoc, et particulièrement un dispositif pour emballer et protéger des objets fragiles à transporter tel que des bouteilles en verre ou analogues ainsi qu'un procédé de fabrication du dispositif d'emballage et de protection associé.The present invention relates to a packaging and shockproof protection device, and particularly a device for packaging and protecting fragile objects to be transported, such as glass bottles or the like, as well as a method of manufacturing the packaging and protection device. associated.

L'emballage d'objets structurellement fragiles à transporter devient de plus en plus primordial pour les consommateurs, devant ainsi permettre une protection optimale tout en ne représentant pas un encombrement important, et devant être esthétiquement satisfaisant.The packaging of structurally fragile objects to be transported is becoming more and more essential for consumers, thus having to allow optimum protection while not representing a significant bulk, and having to be aesthetically satisfactory.

On connait des emballages papiers, ou cartonnés comprenant une structure multicouche et comprenant au moins une structure comportant au moins une couche de papier ondulé ou alvéolaire, apte à absorber les chocs en cas de chute de l'objet ou de contact avec une surface dure. Ces surfaces ne permettent en revanche pas d'épouser la forme de l'objet à protéger ce qui permet le mouvement de l'objet dans ledit emballage.Paper or cardboard packaging comprising a multilayer structure and comprising at least one structure comprising at least one layer of corrugated or alveolar paper, capable of absorbing shocks in the event of the object falling or coming into contact with a hard surface, is known. These surfaces, on the other hand, do not make it possible to match the shape of the object to be protected, which allows the movement of the object in said packaging.

On connait aussi des emballages épousant la forme de l'objet à protéger, n'accordant cependant pas une protection satisfaisante au regard de la fragilité de l'objet à protéger.There are also known packages that match the shape of the object to be protected, but do not provide satisfactory protection with regard to the fragility of the object to be protected.

On connait en outre des dispositifs de calage à insérer dans un emballage de forme standard, ces dispositifs de calage comportant au moins une couche de carton de type en accordéon. Ces dispositifs ne couvrent en général pas toute la surface de l'objet à protéger et sont à utiliser en combinaison avec un emballage plus robuste.We also know wedging devices to be inserted into a package of standard shape, these wedging devices comprising at least one layer of concertina-type cardboard. These devices generally do not cover the entire surface of the object to be protected and are to be used in combination with more robust packaging.

On connaît des documents DE202017 003177U1 , FR2571028A3 , US1940596A et US2646165A des dispositifs d'emballage et de protection d'un objet ayant un axe de révolution.We know documents DE202017 003177U1 , FR2571028A3 , US1940596A And US2646165A devices for packaging and protecting an object having an axis of revolution.

L'invention remédie à ces inconvénients et améliore la situation.The invention overcomes these drawbacks and improves the situation.

Elle porte sur un dispositif d'emballage et de protection pour emballer un objet à protéger ayant un axe de révolution vertical.It relates to a packaging and protection device for packaging an object to be protected having a vertical axis of revolution.

Selon une définition générale de l'invention, le dispositif d'emballage et de protection comprend un corps constitué d'un assemblage de feuilles de papier contrecollées selon une structure en accordéon comportant des arêtes verticales, ledit corps étant déployable radialement autour de l'axe de révolution de l'objet d'une condition plate dans laquelle l'assemblage de feuilles est à plat à une condition déployée dans laquelle l'assemblage de feuilles enveloppe et épouse sensiblement la totalité de la surface externe de l'objet à protéger et le corps en condition déployée comprend une surface externe en accordéon comportant des arêtes verticales, et dans lequel le grammage des feuilles de papier est compris entre 100 g/m2 et 400 g/m2 tandis que le nombre de feuilles est compris entre 20 et 50 feuilles, nombre et grammage choisis l'un et l'autre en fonction des propriétés de protection et d'indice anti choc à conférer vis-à-vis de l'objet à protéger.According to a general definition of the invention, the packaging and protection device comprises a body consisting of an assembly of sheets of paper laminated according to an accordion structure comprising vertical edges, said body being deployable radially around the axis of revolution of the object from a flat condition in which the sheet assembly is flat to an expanded condition in which the sheet assembly wraps and conforms substantially to the entire outer surface of the object to protect and the body in the deployed condition comprises an outer concertina surface having vertical edges, and in which the grammage of the sheets of paper is between 100 g/m2 and 400 g/m2 while the number of sheets is between 20 and 50 sheets, number and weight both chosen according to the protection properties and anti-shock index to be conferred on the object to be protected.

Avantageusement, une telle structure permet un calage optimisé de l'objet à protéger dans le dispositif tout en garantissant une protection intégrale de celui-ci, ladite structure en accordéon conférant des propriétés anti choc amélioré.Advantageously, such a structure allows optimized wedging of the object to be protected in the device while guaranteeing full protection of the latter, said concertina structure conferring improved anti-shock properties.

Le choix de propriétés particulières de grammage et de nombre de feuilles dans cette gamme de grammage n'est pas un choix générique qui serait évident pour l'homme du métier, ni commun dans la pratique, car celui permet, en combinaison avec la structure interne et externe du dispositif de permettre une rigidité suffisante pour ne pas trop se déformer en cas de choc, et suffisamment flexible de manière à absorber ledit choc afin que l'objet à protéger ne soit pas endommagé par transmission du choc.The choice of particular properties of grammage and number of sheets in this range of grammages is not a generic choice which would be obvious to those skilled in the art, nor common in practice, since that allows, in combination with the internal structure and external of the device to allow sufficient rigidity not to deform too much in the event of an impact, and sufficiently flexible so as to absorb said impact so that the object to be protected is not damaged by transmission of the impact.

En pratique, le corps en condition déployée comprend une surface externe en accordéon, apte à être mise en contact avec un élément percutant lors d'un choc, et apte à absorber une partie de l'énergie dudit choc.In practice, the body in the deployed condition comprises an concertina-like outer surface, capable of being brought into contact with a striking element during an impact, and capable of absorbing part of the energy of said impact.

Selon un mode de réalisation de l'invention, le corps comprend deux plaques d'extrémités, disposées sur chaque extrémité de l'assemblage de feuilles de papier, lesdites plaques étant éloignées l'une de l'autre lorsque que le corps est en condition plate, et en contact l'une à l'autre lorsque le corps est en condition déployée de manière à envelopper et épouser sensiblement la surface externe de l'objet à protéger.According to one embodiment of the invention, the body comprises two end plates, arranged on each end of the assembly of sheets of paper, said plates being remote from each other when the body is in working condition. flat, and in contact with each other when the body is in the deployed condition so as to envelop and substantially conform to the outer surface of the object to be protected.

A titre d'exemple, les plaques d'extrémités sont réalisées en matériau renforcé appartenant au groupe formé par : carton rigide, plexiglass, bois, métal.By way of example, the end plates are made of reinforced material belonging to the group formed by: rigid cardboard, plexiglass, wood, metal.

En outre, les deux plaques d'extrémités du corps comprennent des moyens de verrouillage, apte à verrouiller le dispositif lorsque le corps est en condition déployée.In addition, the two end plates of the body comprise locking means, capable of locking the device when the body is in the deployed condition.

Selon un mode de réalisation particulier de l'invention, les deux plaques d'extrémités du corps comprennent chacune une structure formant languette, disposée sur une partie supérieure de chaque plaque d'extrémité, et permettant le déploiement et le pliage du corps de la condition plate à la condition déployée et vice versa.According to a particular embodiment of the invention, the two end plates of the body each comprise a structure forming a tongue, arranged on an upper part of each end plate, and allowing the deployment and folding of the body in the condition flat to the deployed condition and vice versa.

En pratique, les moyens de verrouillage appartiennent au groupe formé par mécanisme magnétique, mécanisme à bouton, mécanisme à scratch, mécanisme scotch double face, ruban.In practice, the locking means belong to the group formed by magnetic mechanism, button mechanism, scratch mechanism, double-sided tape mechanism, tape.

L'invention porte en outre sur un procédé de fabrication d'un dispositif d'emballage et de protection conforme à l'invention.The invention further relates to a method for manufacturing a packaging and protection device according to the invention.

Selon une définition générale de l'invention, le procédé comprend les étapes suivantes :

  • contrecoller sélectivement et partiellement des feuilles de papier de grammage et nombre choisis et selon des positions choisies ;
  • Découper l'assemblage de feuilles ainsi contrecollé selon un plan de découpe interne choisi, lorsque le nombre de feuille à contrecoller est atteint ;
  • Découper un plan de découpe externe choisi ; et
  • Contrecoller les tranches des parties haute et basse du corps du dispositif d'emballage ainsi obtenu.
According to a general definition of the invention, the method comprises the following steps:
  • selectively and partially laminating sheets of paper of chosen weight and number and according to chosen positions;
  • Cut the assembly of sheets thus laminated according to a chosen internal cutting plan, when the number of sheets to be laminated is reached;
  • Cut a selected external cutting plane; And
  • Laminate the edges of the upper and lower parts of the body of the packaging device thus obtained.

De manière surprenante, le Demandeur a observé que la structure en accordéon du dispositif selon l'invention combiné à sa structure interne épousant la forme de l'objet à protéger permet d'obtenir une protection antichoc améliorée, tout en étant léger, spatialement non encombrant, facile d'utilisation et à produire, et peu onéreux pour l'utilisateur.Surprisingly, the Applicant has observed that the concertina structure of the device according to the invention combined with its internal structure matching the shape of the object to be protected makes it possible to obtain improved shock protection, while being light, spatially not bulky. , easy to use and produce, and inexpensive for the user.

La tranche interne 231 dispose en outre d'une partie basse interne 241 et d'une partie haute interne 251 disposées selon un axe, ci-après nommé axe de révolution, autour duquel le déploiement du corps 2 du dispositif 1 s'effectue.The internal slice 231 also has an internal lower part 241 and an internal upper part 251 arranged along an axis, hereinafter called the axis of revolution, around which the deployment of the body 2 of the device 1 takes place.

La tranche interne 231 comprend en outre une découpe selon un plan de révolution 6 de l'objet à protéger 5 de manière à épouser la forme de celui-ci lors du passage en condition déployée.The inner edge 231 further comprises a cutout along a plane of revolution 6 of the object to be protected 5 so as to match the shape of the latter during the transition to the deployed condition.

Selon un mode de réalisation conforme à l'invention, en condition plate le corps 2 comprend en outre au moins deux plaques d'extrémités 3, disposées sur chaque extrémité de l'assemblage de feuilles de papier 23.According to an embodiment in accordance with the invention, in flat condition the body 2 further comprises at least two end plates 3, arranged on each end of the assembly of sheets of paper 23.

En pratique, les deux plaques d'extrémités 3 sont parallèles l'une par rapport à l'autre lorsque que le corps 2 est en condition plate, et sont configurées pour être mises en contact l'une à l'autre lorsque le corps 2 est en condition déployée de manière à envelopper et épouser sensiblement la surface externe 24 de l'objet à protéger 5.In practice, the two end plates 3 are parallel to each other when the body 2 is in the flat condition, and are configured to be brought into contact with each other when the body 2 is in the deployed condition so as to envelop and substantially hug the outer surface 24 of the object to be protected 5.

A titre d'exemple non limitatif, matériau renforcé appartient au groupe formé par : carton rigide, plexiglass, bois, métal.By way of non-limiting example, reinforced material belongs to the group formed by: rigid cardboard, plexiglass, wood, metal.

Les deux plaques d'extrémités 3 du corps 2 comprennent en outre des moyens de verrouillage 4, apte à verrouiller le dispositif 1 lorsque le corps 2 est en condition déployée autour de l'objet 5, permettant ainsi de maintenir une protection uniforme de l'objet 5 en cas de choc.The two end plates 3 of the body 2 further comprise locking means 4, capable of locking the device 1 when the body 2 is in the deployed condition around the object 5, thus making it possible to maintain uniform protection of the object 5 in the event of impact.

En pratique, les moyens de verrouillage 4 appartiennent au groupe formé par mécanisme magnétique, mécanisme à bouton, mécanisme à scratch, scotch double face, ruban.In practice, the locking means 4 belong to the group formed by magnetic mechanism, button mechanism, scratch mechanism, double-sided tape, tape.

Selon un mode de réalisation particulier, chaque plaque d'extrémité 3 comprend au moins un moyen magnétique 42 de verrouillage 4 disposé sur sa partie haute 25, et au moins un moyen magnétique 42 de verrouillage 4 disposé sur sa partie basse 24, permettant ainsi une mise en contact des moyens magnétiques 42, respectivement en partie haute 25 et basse 24 en condition déployée, initiant ainsi le verrouillage du dispositif 1.According to a particular embodiment, each end plate 3 comprises at least one magnetic locking means 42 4 placed on its upper part 25, and at least one magnetic locking means 42 4 placed on its lower part 24, thus allowing a bringing the magnetic means 42 into contact, respectively at the top 25 and bottom 24 in the deployed condition, thus initiating the locking of the device 1.

Alternativement, la tranche externe 232 comprend une dépression, apte à former un évidement annulaire 41 en condition déployée, configurée pour recevoir un ruban circulaire, parcourant complètement le périmètre externe du corps 2 ainsi déployé, et apte à permettre le verrouillage du dispositif 1 en condition déployée.Alternatively, the outer edge 232 comprises a depression, capable of forming an annular recess 41 in the deployed condition, configured to receive a circular ribbon, completely traversing the outer perimeter of the body 2 thus deployed, and capable of allowing the device 1 to be locked in the deployed condition. deployed.

La structure formant languette 26 permet une meilleure préhension des plaques d'extrémités 3 pour que l'utilisateur exécute la transition entre la condition plate et la condition déployée.The tongue structure 26 allows better gripping of the endplates 3 for the user to perform the transition between the flat condition and the deployed condition.

En condition déployée, le corps 2 comprend une surface externe 21 en accordéon correspondant à la version déployée de la tranche externe 232, et apte à être mise en contact avec un élément percutant lors d'un choc afin d'absorber une partie de l'énergie dudit choc.In deployed condition, the body 2 comprises an accordion-shaped outer surface 21 corresponding to the deployed version of the outer edge 232, and capable of being brought into contact with a striking element during an impact in order to absorb part of the energy of said shock.

Le corps 2 du dispositif 1 comprend en outre une surface interne 22 correspondant à la version déployée de la tranche interne 231, formant en condition déployée un évidemment radial central dans lequel l'objet à protéger 5 est inséré.The body 2 of the device 1 further comprises an internal surface 22 corresponding to the deployed version of the internal edge 231, forming in the deployed condition a central radial recess in which the object to be protected 5 is inserted.

Selon un mode de réalisation de l'invention, la surface interne 22 est aménagée selon une révolution du plan de révolution 6 formé par la tranche interne 231, de manière à épouser la forme de l'objet à protéger 5, et ainsi permettre un calage précis, limitant la capacité de mouvement dudit l'objet 5 dans le dispositif 1.According to one embodiment of the invention, the internal surface 22 is arranged according to a revolution of the plane of revolution 6 formed by the internal edge 231, so as to match the shape of the object to be protected 5, and thus allow a wedging precise, limiting the movement capacity of said object 5 in device 1.

Lorsque le dispositif 1 est complètement déployé, la surface interne 22 recouvre la totalité de l'objet à protéger 5, de manière à assurer une protection uniforme en tout point de l'objet 5.When the device 1 is completely deployed, the internal surface 22 covers the whole of the object to be protected 5, so as to ensure uniform protection at all points of the object 5.

En pratique, le déploiement radial s'effectue sur 360°.In practice, the radial deployment takes place over 360°.

Selon un premier mode de réalisation conforme à l'invention, la tranche externe 232 du corps 2 dispose d'un plan de coupe vertical droit, formant sensiblement un rectangle, permettant ainsi en condition déployée de former une surface externe 21 cylindrique.According to a first embodiment in accordance with the invention, the outer edge 232 of the body 2 has a straight vertical section plane, substantially forming a rectangle, thus making it possible, in the deployed condition, to form a cylindrical outer surface 21 .

Selon un second mode de réalisation conforme à l'invention, la tranche externe 232 du corps 2 dispose d'une découpe comportant une arête parallèle à la tranche interne 231, permettant ainsi en condition déployée de former une surface externe 21 reproduisant la surface externe de l'objet à protéger 5 et permettant d'obtenir un corps 2 d'épaisseur égale en tout point de l'objet 5.According to a second embodiment in accordance with the invention, the outer edge 232 of the body 2 has a cutout comprising an edge parallel to the inner edge 231, thus making it possible, in the deployed condition, to form an outer surface 21 reproducing the outer surface of the object to be protected 5 and making it possible to obtain a body 2 of equal thickness at all points of the object 5.

En pratique, la tranche externe 232 du corps 2 dispose d'une découpe selon un plan de coupe externe 62 choisi, permettant ainsi en condition déployée de former une surface externe 21 de forme appartenant non limitativement au groupe formé par pomme, oeuf, toupie, cloche, ou tout autre forme comportant un axe de révolution 61.In practice, the outer edge 232 of the body 2 has a cutout according to a chosen outer cutting plane 62, thus making it possible, in the deployed condition, to form an outer surface 21 of a shape belonging, without limitation, to the group formed by apple, egg, spinning top, bell, or any other shape comprising an axis of revolution 61.

Selon un mode de réalisation de l'invention, l'assemblage de feuilles de papier contrecollées 23 comprend un nombre de feuilles et un grammage choisis l'un et l'autre en fonction des propriétés de protection et d'indice antichoc à conférer vis-à-vis de l'objet à protéger 5.According to one embodiment of the invention, the assembly of laminated sheets of paper 23 comprises a number of sheets and a basis weight both chosen according to the protective properties and the shockproof index to be conferred vis- against the object to be protected 5.

En pratique, plus le grammage est élevé, plus le dispositif 1 est résistant aux chocs.In practice, the higher the weight, the more the device 1 is shock resistant.

Conformément à l'invention, le grammage choisi est compris entre 100 g/m2 et 400 g/m2, de manière à obtenir un dispositif 1 suffisamment rigide pour ne pas trop se déformer en cas de choc, et suffisamment flexible de manière à absorber ledit choc contre le dispositif.In accordance with the invention, the basis weight chosen is between 100 g/m 2 and 400 g/m 2 , so as to obtain a device 1 which is sufficiently rigid not to deform in the event of an impact, and flexible enough to absorb said impact against the device.

Conformément à l'invention, le nombre de feuilles compris dans l'assemblage de feuilles de papier contrecollées 23 est compris entre 20 et 50 feuilles.According to the invention, the number of sheets included in the assembly of laminated paper sheets 23 is between 20 and 50 sheets.

De manière surprenante, le Demandeur a observé que le choix de grammage et de nombre de feuilles permet d'obtenir un niveau de protection de l'objet adapté à la structure implémentée tout en garantissant l'absorption des chocs, la déformation du dispositif et la minimisation du transfert de l'énergie libérée dans le dispositif pour éviter que l'objet à protéger soit endommagé.Surprisingly, the Applicant has observed that the choice of weight and number of sheets makes it possible to obtain a level of protection of the object adapted to the structure implemented while guaranteeing the absorption of shocks, the deformation of the device and the minimization of the transfer of the energy released in the device to prevent the object to be protected from being damaged.

Le choix de propriétés particulières de grammage et de nombre de feuilles dans cette gamme de grammage n'est pas un choix générique qui serait évident pour l'homme du métier, ni commun dans la pratique, car celui permet, en combinaison avec la structure interne et externe du dispositif de permettre une rigidité suffisante pour ne pas trop se déformer en cas de choc, et suffisamment flexible de manière à absorber ledit choc afin que l'objet à protéger ne soit pas endommagé par transmission du choc.The choice of particular properties of grammage and number of sheets in this range of grammages is not a generic choice which would be obvious to those skilled in the art, nor common in practice, since that allows, in combination with the internal structure and external of the device to allow sufficient rigidity not to deform too much in the event of an impact, and sufficiently flexible so as to absorb said impact so that the object to be protected is not damaged by transmission of the impact.

A titre d'exemple, un tel grammage et nombre de feuille appliqué à la structure du corps 2 permet de maintenir l'intégrité physique d'une bouteille telle qu'une bouteille de champagne de 75cl remplie de liquide et pesant entre 1,5 et 2 Kg, lâchée en chute libre depuis un point de chute à un mètre de hauteur et dont l'impact est effectué sur une surface dure (sol de type carrelage, béton, ou surface de dureté similaire).By way of example, such a weight and number of sheets applied to the structure of the body 2 makes it possible to maintain the physical integrity of a bottle such as a 75 cl bottle of champagne filled with liquid and weighing between 1.5 and 2 Kg, dropped in free fall from a point of fall at a height of one meter and whose impact is carried out on a hard surface (floor of the tiled type, concrete, or surface of similar hardness).

Ces choix particuliers de grammage et de nombre de feuilles adaptés à la structure du corps 2 permet donc au dispositif d'être suffisamment rigide pour ne pas trop se déformer en cas de choc, et suffisamment flexible de manière à absorber ledit choc tout en optimisant le degré de protection de l'objet à protéger.These particular choices of grammage and number of sheets adapted to the structure of the body 2 therefore allow the device to be sufficiently rigid not to deform too much in the event of an impact, and sufficiently flexible so as to absorb said impact while optimizing the degree of protection of the object to be protected.

Selon l'invention, le contrecollage des feuilles 23 à assembler est effectué de manière à ce que la structure en accordéon comporte des arrêtes verticales.According to the invention, the lamination of the sheets 23 to be assembled is carried out so that the concertina structure has vertical edges.

Selon un mode de réalisation particulier conforme à l'invention, le dispositif 1 selon l'invention comprend un corps 2 en deux parties formant chacun une révolution à 180°.According to a particular embodiment in accordance with the invention, the device 1 according to the invention comprises a body 2 in two parts each forming a 180° revolution.

La structure formant languette 26 permet une meilleure préhension des plaques d'extrémités 3 pour que l'utilisateur exécute la transition entre la condition plate et la condition déployée, ladite structure formant languette étant disposé sur chaque extrémité de déploiement.The structure forming a tongue 26 allows better gripping of the end plates 3 so that the user executes the transition between the flat condition and the deployed condition, said structure forming a tongue being arranged on each deployment end.

En condition déployée, le corps 2 en deux parties comprend une surface externe 21 en accordéon correspondant à la version déployée de chaque tranche externe 232, et apte à être mise en contact avec la seconde partie identique pour former le corps 2 selon une révolution de 360° autour de l'objet à protéger, et formant en condition déployée un évidemment radial central dans lequel l'objet à protéger 5 est inséré.In the deployed condition, the two-part body 2 comprises an accordion-shaped outer surface 21 corresponding to the deployed version of each outer slice 232, and capable of being brought into contact with the second identical part to form the body 2 according to a revolution of 360 ° around the object to be protected, and forming in deployed condition a central radial recess in which the object to be protected 5 is inserted.

Selon un mode de réalisation de l'invention, la surface interne 22 est aménagée selon une révolution du plan de révolution 6 formé par la tranche interne 231, de manière à épouser la forme de l'objet à protéger 5, et ainsi permettre un calage précis, limitant la capacité de mouvement dudit l'objet 5 dans le dispositif 1 par verrouillage de chaque extrémité plate l'une par rapport à l'autre par mise en place de moyens de verrouillage.According to one embodiment of the invention, the internal surface 22 is arranged according to a revolution of the plane of revolution 6 formed by the internal edge 231, so as to match the shape of the object to be protected 5, and thus allow a wedging precise, limiting the movement capacity of said object 5 in device 1 by locking each flat end relative to the other by installing locking means.

En pratique, les moyens de verrouillage appartient au groupe formé par moyen magnétique 42 de verrouillage 4 disposé sur sa partie haute 25, et au moins un moyen magnétique 42 de verrouillage 4 disposé sur sa partie basse 24, permettant ainsi une mise en contact des moyens magnétiques 42, respectivement en partie haute 25 et basse 24 en condition déployée, initiant ainsi le verrouillage du dispositif 1, languette insérable dans un évidemment sur la surface complémentaire, bouton à clip ou analogue.In practice, the locking means belongs to the group formed by magnetic locking means 42 4 disposed on its upper part 25, and at least one magnetic locking means 42 4 disposed on its lower part 24, thus allowing contacting of the means magnetic 42, respectively in the upper part 25 and lower part 24 in deployed condition, thus initiating the locking of the device 1, tongue insertable in a recess on the complementary surface, clip button or the like.

En référence à la figure 10 , l'invention porte aussi sur un procédé de fabrication du dispositif de protection tel que décrit.With reference to the figure 10 , the invention also relates to a method of manufacturing the protection device as described.

Le procédé selon l'invention comprend les étapes suivantes :The method according to the invention comprises the following steps:

Selon une première étape S1 chaque feuille 23 est contrecollé partiellement sur des zones précises sélectionnées de manière à obtenir une structure en accordéon.According to a first step S1, each sheet 23 is partially laminated on specific areas selected so as to obtain an accordion structure.

Selon une seconde étape S2, après chaque contrecollage, chaque feuille est assemblée jusqu'à ce que le nombre de feuilles 23 cible soit atteint.According to a second step S2, after each lamination, each sheet is assembled until the target number of sheets 23 is reached.

Selon une troisième étape S3, l'assemblage de feuilles ainsi contrecollé 23 obtenu subit une découpe selon un plan de découpe choisi correspondant au plan de révolution 6 de l'objet à protéger 5. Additionnellement, l'assemblage de feuilles ainsi contrecollé 23 obtenu subit une découpe selon un plan de découpe externe 62 choisi.According to a third step S3, the assembly of sheets thus laminated 23 obtained undergoes cutting according to a chosen cutting plane corresponding to the plane of revolution 6 of the object to be protected 5. Additionally, the assembly of sheets thus laminated 23 obtained undergoes a cut according to an external cutting plane 62 chosen.

Selon une dernière étape S4, les tranches 241, 251 des parties haute 25 et basse 24 du corps 2 du dispositif d'emballage 1 ainsi obtenu sont contrecollées de manière à permettre le déploiement radial du dispositif 1.According to a last step S4, the edges 241, 251 of the upper 25 and lower 24 parts of the body 2 of the packaging device 1 thus obtained are laminated so as to allow the radial deployment of the device 1.

De manière surprenante, le Demandeur a observé que le dispositif 1 selon l'invention permettait d'obtenir un élément de protection léger, résistant et comportant des propriétés d'absorption anti choc optimisées, et facilement utilisable et adaptable à tout type d'objet comprenant un axe de révolution 61.Surprisingly, the Applicant has observed that the device 1 according to the invention makes it possible to obtain a light, resistant protective element comprising optimized anti-shock absorption properties, and easily usable and adaptable to any type of object comprising an axis of revolution 61.

Les choix de grammage et de nombre de feuilles à contrecoller de grammage ciblé en combinaison avec une structure choisie et des conditions de stockage de l'objet à protéger bien définies dans le dispositif permettent d'obtenir un effet technique singulier permettant le déploiement aisé de la structure radialement tout en renforçant significativement la protection des objets intégrés dans le dispositif, dénotant un choix technique spécifique et non une pratique générique dont serait capable l'homme du métier.The choice of grammage and number of sheets to be laminated with a targeted grammage in combination with a chosen structure and well-defined storage conditions for the object to be protected in the device make it possible to obtain a singular technical effect allowing the easy deployment of the structure radially while significantly reinforcing the protection of the objects integrated into the device, denoting a specific technical choice and not a generic practice of which a person skilled in the art would be capable.
