Description

L'invention concerne le domaine des emballages en carton ou autre matériau semi-rigide. Elle vise l'emballage d'un produit se présentant sous la forme d'une feuille rigide, plate ou galbée, telle qu'un pare-brise, une porte, un capot de véhicule ou autre élément de carrosserie, un vitrage, un panneau d'isolation, ...The invention relates to the field of packaging in cardboard or other semi-rigid material. It refers to the packaging of a product in the form of a rigid sheet, flat or curved, such as a windshield, a door, a hood of a vehicle or other bodywork element, a glazing, a panel insulation, ...

On souhaite souvent emballer les pare-brise dans des emballages individuels, afin de les conditionner et de pouvoir les transporter en les protégeant des chocs, que ce soit depuis leur lieu de fabrication jusqu'au lieu de montage, sur le lieu même du montage pour les déplacer au sein des ateliers ou dans un atelier de réparation. Ces emballages individuels permettent de manipuler, transporter et stocker les pare-brise à l'unité.It is often desired to pack the windshields in individual packages, in order to package them and to be able to transport them by protecting them from shocks, whether from their place of manufacture to the assembly site, at the place of assembly for move them in the workshops or in a repair shop. These individual packages make it possible to handle, transport and store windshields to the unit.

On connaît de tels emballages, par exemple par le brevet EP 0 133 085 . L'emballage décrit dans ce dernier est constitué d'un flan de carton rectangulaire formé d'un panneau central sur lequel le pare-brise est placé, prolongé par deux panneaux latéraux qui sont rabattus sur celui-ci. Des découpes sont pratiquées transversalement sur le flan et servent de logements à deux feuillards cerclant et maintenant la cohésion de l'ensemble.Such packagings are known, for example by the patent EP 0 133 085 . The packaging described in the latter consists of a rectangular cardboard blank formed of a central panel on which the windshield is placed, extended by two side panels which are folded on it. Cuttings are made transversely on the blank and serve as housing with two straps circling and maintaining the cohesion of the whole.

D'autres emballages sont connus de US 6 672 035 B, US 5 860 524 A ou FR 2 760 729 A .Other packages are known to US 6,672,035 B US 5,860,524 A or FR 2 760 729 A .

La présente invention vise :

  • à simplifier les opérations et les manipulations des pièces au moment de la mise sous emballage du produit,
  • à faciliter la prise en main d'un produit emballé,
  • à ce que le produit emballé occupe un volume aussi faible que possible pendant son stockage, et son expédition,
  • à réduire le temps de mise à disposition du produit quand on l'extrait de son emballage,
  • à réduire la quantité de matière utilisée et
  • à assurer une protection efficace contre les chocs éventuels reçus. La demanderesse s'est notamment fixé comme objectif, pour un produit pesant entre 10 et 50 kg, que l'emballage puisse amortir, sans effet négatif sur le produit, plusieurs chutes verticales d'une trentaine de centimètres sur son bord inférieur, et retourné de 180°, sur le bord supérieur.
The present invention aims to:
  • to simplify the operations and handling of the parts at the time of packaging the product,
  • to facilitate the handling of a packaged product,
  • the packaged product occupies as little volume as possible during its storage, and its shipment,
  • to reduce the time of availability of the product when it is extracted from its packaging,
  • to reduce the amount of material used and
  • to provide effective protection against possible shocks received. The plaintiff has set itself the objective, for a product weighing between 10 and 50 kg, that the packaging can cushion, without any negative effect on the produced, several vertical drops of about thirty centimeters on its lower edge, and turned 180 °, on the upper edge.

A cet effet, l'invention concerne un emballage pour le conditionnement en position verticale d'un produit en forme de feuille rigide comprenant une plaque en matériau semi-rigide pour recouvrir au moins partiellement ladite feuille, la plaque comportant un moyen de liaison par adhésif par lequel la feuille rigide est rendue solidaire de la plaque, et peut être maintenue en suspension lorsque la plaque est maintenue dressée en position verticale, caractérisé par le fait que la plaque comprend un bord supérieur, deux panneaux latéraux, articulés autour d'au moins une ligne de pliage, et un panneau inférieur, articulé autour d'au moins une ligne de pliage, destinés à recouvrir au moins en partie la feuille rigide, les panneaux latéraux et le panneau inférieur étant agencés pour former des pieds du côté inférieur, une fois la feuille recouverte par lesdits panneaux, et par le fait que le moyen de liaison comprend au moins un élément en mousse de matière plastique revêtu d'une première matière adhésive côté feuille rigide et une deuxième matière adhésive côté plaque, le moyen de liaison étant agencé pour, en cas de chute depuis une hauteur déterminée et la feuille étant dressée en position verticale, assurer le maintien du produit en position contre la plaque dans l'emballage.To this end, the invention relates to a packaging for the vertical packaging of a rigid sheet-shaped product comprising a plate of semi-rigid material for at least partially covering said sheet, the plate comprising an adhesive bonding means. whereby the rigid sheet is made integral with the plate, and can be kept in suspension when the plate is held upright in a vertical position, characterized in that the plate comprises an upper edge, two side panels, articulated around at least a fold line, and a lower panel, hinged about at least one fold line, for at least partially covering the rigid sheet, the side panels and the bottom panel being arranged to form bottom legs, a the sheet covered by said panels, and in that the connecting means comprises at least one plastic foam element a first adhesive material on the rigid sheet side and a second adhesive material on the plate side, the connecting means being arranged to, in the event of a fall from a given height and the sheet being erected in a vertical position, to maintain the product in position against the plate in the package.

De préférence, l'élément est en forme de feuille, par exemple en mousse de polyéthylène ou de polyuréthane. La mousse est à la fois résiliente et souple.Preferably, the element is in sheet form, for example polyethylene foam or polyurethane. Foam is both resilient and flexible.

La feuille a avantageusement une épaisseur de 1 à 1,5 mm.The sheet advantageously has a thickness of 1 to 1.5 mm.

On a constaté avec surprise que le matériau en mousse résiliente convenait parfaitement au support de charges lourdes et fragiles que sont les pare-brise de véhicules automobiles. La mousse permet un contact de meilleure qualité avec une surface non parfaitement plane comme celle du carton ondulé car elle en épouse le relief. Un contact de meilleure qualité signifie aussi que la surface de la pellicule de matière adhésive au contact des surfaces à lier est optimale donc la liaison plus efficace par rapport à un simple ruban adhésif.It has been surprisingly found that the resilient foam material is ideally suited for supporting heavy and fragile loads that are the windshields of motor vehicles. The foam allows a better quality of contact with a surface not perfectly flat like that of the corrugated cardboard because it marries the relief. Better contact also means that the surface of the adhesive film in contact with surfaces to bind is optimal so the binding more effective compared to a simple tape.

La mousse élastique a également une fonction d'absorption de l'énergie de chute d'où un amortissement élastique et une plus grande efficacité de résistance aux chocs.The elastic foam also has a drop energy absorption function, hence elastic damping and greater impact resistance.

Avantageusement, le moyen de liaison comprend une pluralité d'éléments. Par exemple dans le cas d'un pare brise, le moyen de liaison est constitué de trois ou quatre bandes ou rubans. Ces bandes peuvent par exemple être de 25mm de large sur 500mm de long. Avantageusement encore, l'élément comprend une première matière adhésive côté feuille rigide et une deuxième matière adhésive côté plaque, différentes. L'objectif est notamment d'adapter l'adhésif à la nature de la surface sur laquelle il est apposé ; en outre, industriellement, il est souhaitable que l'adhésif ne laisse pas de traces sur la feuille rigide, pare-brise en particulier.Advantageously, the connecting means comprises a plurality of elements. For example in the case of a windshield, the connecting means consists of three or four bands or ribbons. These strips may for example be 25mm wide by 500mm long. Advantageously, the element comprises a first rigid sheet-side adhesive material and a second, different plate-side adhesive material. The objective is in particular to adapt the adhesive to the nature of the surface on which it is affixed; in addition, industrially, it is desirable that the adhesive does not leave traces on the rigid sheet, windshield in particular.

De préférence dans ce cas, les panneaux latéraux et le panneau inférieur comprennent des moyens de verrouillage les uns aux autres.Preferably in this case, the side panels and the bottom panel comprise locking means to each other.

Selon une autre caractéristique de l'invention, la plaque comprend des lignes de pliage pour faciliter la déformation de la plaque et son application contre la feuille rigide lorsque celle-ci n'est pas plane.According to another characteristic of the invention, the plate comprises fold lines to facilitate the deformation of the plate and its application against the rigid sheet when it is not flat.

Selon une autre caractéristique de l'invention, la plaque comporte des poignées latérales par lesquelles on peut le saisir.According to another characteristic of the invention, the plate has lateral handles through which it can be grasped.

Avantageusement, l'emballage comprend également une enveloppe en matériau plastique thermo-rétractable pour recouvrir l'ensemble formé par la plaque et la feuille.Advantageously, the package also comprises a heat-shrinkable plastic material envelope for covering the assembly formed by the plate and the sheet.

Dans la forme de réalisation préférée de l'invention, la plaque est en carton ondulé, qui comporte des cannelures perpendiculaires au bord supérieur.In the preferred embodiment of the invention, the plate is made of corrugated cardboard, which has grooves perpendicular to the upper edge.

The corrugated cardboard generally comprises two cover sheets, between which are arranged one or more layers of grooves, which extend in the direction shown schematically by the lines contained in the triangle 2 which has been drawn on the plate 1 of the Figures 1 and 2 . This representation of the direction of the grooves is well known to those skilled in the art.

La plaque peut aussi être réalisée à partir d'un autre matériau semi-rigide, par exemple un matériau plastique alvéolaire tel que le produit vendu sous la marque enregistrée Akylux par la demanderesse.The plate may also be made from another semi-rigid material, for example a cellular plastic material such as the product sold under the registered trademark Akylux by the applicant.

La plaque 1 est ici de forme globalement rectangulaire, pour une feuille rigide, par exemple un pare-brise, de forme aussi globalement rectangulaire. D'autres formes sont possibles, par exemple semi-ovale.The plate 1 is here of generally rectangular shape, for a rigid sheet, for example a windshield, also of generally rectangular shape. Other forms are possible, for example semi-oval.

Par raine, on désigne un marquage à la surface de la plaque qui aide à son pliage. Une raine est obtenue par écrasement de la matière le long d'une ligne qui constitue la ligne d'articulation ou bien, dans le cas d'un carton ondulé notamment, par la découpe de l'une des feuilles de couverture le long de cette ligne.By means a marking on the surface of the plate which helps to bend it. A groove is obtained by crushing the material along a line that constitutes the hinge line or, in the case of corrugated cardboard in particular, by cutting one of the cover sheets along this line. line.

La plaque 1 comprend un bord dit supérieur 3, rectiligne. Perpendiculairement à ce bord, deux doubles raines (4, 4') et (5, 5') délimitent un panneau central 6 et deux panneaux latéraux 7, 8. Chaque raine est espacée de l'autre raine de la double raine (4, 4'), (5, 5') à laquelle elle appartient d'une distance "e" correspondant à l'épaisseur, ou un peu plus, de la feuille rigide à emballer.The plate 1 comprises a said upper edge 3, rectilinear. Perpendicular to this edge, two double grooves (4, 4 ') and (5, 5') delimit a central panel 6 and two side panels 7, 8. Each groove is spaced from the other groove of the double groove (4, 4 '), (5, 5') to which it belongs by a distance "e" corresponding to the thickness, or a little more, of the rigid sheet to be wrapped.

Dans la suite de la description, on considérera que la plaque 1 s'étend dans un plan vertical, avec son bord supérieur 3 placé en haut. L'ensemble des éléments de la plaque sera décrit dans ce référentiel. On note que, si la plaque 1 est en carton ondulé, ses cannelures s'étendent verticalement.In the remainder of the description, it will be considered that the plate 1 extends in a vertical plane, with its upper edge 3 placed at the top. All elements of the plate will be described in this reference. Note that if the plate 1 is corrugated cardboard, its grooves extend vertically.

Le panneau central 6 comporte une portion de surface comprenant un moyen de liaison 9 agencé pour retenir la feuille rigide contre le panneau central 6. Ce moyen est décrit plus loin.The central panel 6 has a surface portion comprising a connecting means 9 arranged to retain the rigid sheet against the central panel 6. This means is described below.

Chaque panneau latéral 7, 8 comprend un bord inférieur 7', 8', respectivement, opposé et parallèle au bord supérieur 3 de la plaque 1. Entre ces bords inférieurs 7', 8', s'étend un panneau inférieur 10 qui prolonge le panneau central 6 vers le bas. Le panneau inférieur 10 s'étend sur toute la longueur du panneau central 6, entre les raines intérieures 4, 5 des doubles raines (4, 4'), (5, 5').Each side panel 7, 8 comprises a lower edge 7 ', 8', respectively opposite and parallel to the upper edge 3 of the plate 1. Between these lower edges 7 ', 8', extends a lower panel 10 which extends the central panel 6 down. The lower panel 10 extends over the entire length of the central panel 6, between the inner channels 4, 5 of the double grooves (4, 4 '), (5, 5').

Le panneau central 6 et le panneau inférieur 10 présentent sur la figure six raines verticales 12 qui s'étendent depuis le bord supérieur 3 de la plaque 1 jusqu'au bord inférieur 13 du panneau inférieur 10. Ce nombre est choisi en fonction du galbe de la feuille et de sa largeur, en particulier. Le panneau central 6 comprend une double raine (11, 11') horizontale, dont les raines 11 et 11' sont espacées de la même distance "e" que précédemment. La double raine (11, 11') s'étend sur toute la longueur située entre les deux raines verticales 12 du panneau central 6 les plus proches des panneaux latéraux 7, 8, mais pas entre ces deux raines verticales 12 et les doubles raines (4, 4'), (5, 5'). La raine inférieure 11' de la double raine (11, 11') s'étend à une altitude "h" au-dessus de l'altitude des bords inférieurs 7', 8' des panneaux latéraux 7, 8.The central panel 6 and the lower panel 10 have in the figure six vertical raines 12 which extend from the upper edge 3 of the plate 1 to the lower edge 13 of the lower panel 10. This number is chosen according to the curve of the leaf and its width, in particular. The central panel 6 comprises a double horizontal raine (11, 11 '), whose Raines 11 and 11 'are spaced the same distance "e" as before. The double groove (11, 11 ') extends over the entire length between the two vertical raines 12 of the central panel 6 closest to the lateral panels 7, 8, but not between these two vertical raines 12 and the double raines ( 4, 4 '), (5, 5'). The lower trench 11 'of the double tread (11, 11') extends at an altitude "h" above the altitude of the lower edges 7 ', 8' of the side panels 7, 8.

Le panneau central 6 comprend en outre deux découpes 14, 14', situées dans sa partie basse et à proximité des panneaux latéraux 7, 8, symétriques l'une de l'autre par rapport à un axe vertical central du panneau central 6. Seule la découpe gauche 14 va être décrite, la découpe 14' se déduisant par symétrie.The central panel 6 further comprises two cutouts 14, 14 ', located in its lower part and near the side panels 7, 8, symmetrical to one another with respect to a central vertical axis of the central panel 6. Only the left cut 14 will be described, the cut 14 'being deduced by symmetry.

La découpe gauche 14 présente tout d'abord un premier segment horizontal 14a, qui prend sa source à gauche au niveau de l'extrémité gauche du bord inférieur 7' du panneau latéral 7 gauche et s'étend vers la droite. Elle comprend ensuite un segment oblique 14b qui s'étend vers le haut et vers la droite. A la suite de ce segment oblique 14b, elle comprend un second segment horizontal 14c qui s'étend vers la droite jusqu'à la raine 12 du panneau central 6 la plus proche du panneau latéral gauche 7. Ce deuxième segment horizontal 14c se situe à une altitude "h" au-dessus de la raine supérieure 11 de la double raine horizontale (11, 11'), qui est la même altitude "h" que celle qui sépare le bord inférieur 7' du panneau latéral gauche 7, et donc le premier segment horizontal 14a, de la raine inférieure 11' de la double raine horizontale (11, 11'). A partir du second segment horizontal 14c, la découpe 14 comprend un segment vertical 14d qui s'étend vers le bas, le long de la raine 12 la plus à gauche, jusqu'à la raine horizontale inférieure 11' de la double raine horizontale (11, 11') du panneau central 6.The left cut 14 firstly presents a first horizontal segment 14a, which has its source on the left at the left end of the lower edge 7 'of the left side panel 7 and extends to the right. It then comprises an oblique segment 14b which extends upwards and to the right. Following this oblique segment 14b, it comprises a second horizontal segment 14c which extends to the right to the groove 12 of the central panel 6 closest to the left lateral panel 7. This second horizontal segment 14c is located at an altitude "h" above the upper raine 11 of the horizontal double rane (11, 11 '), which is the same altitude "h" as that which separates the lower edge 7' of the left side panel 7, and therefore the first horizontal segment 14a, of the lower channel 11 'of the horizontal double channel (11, 11'). From the second horizontal segment 14c, the cutout 14 comprises a vertical segment 14d which extends downwards, along the leftmost groove 12, to the lower horizontal groove 11 'of the horizontal double groove ( 11, 11 ') of the central panel 6.

En référence aux figures 3 et 4, le moyen de liaison adhésif 9 se présente sous la forme ici de trois éléments 15a, 15b et 15c en forme de rubans ou de bandes parallèles entre eux, et disposés verticalement à une distance les uns des autres. Sur le mode de réalisation représenté, le rectangle formé à une hauteur au moins deux fois plus grande que la largeur. Sur une première face, la face avant, les éléments 15a, 15b et 15c sont revêtus de façon uniforme d'une enduction d'une première matière adhésive 16a, 16b, 16c. Cette matière adhésive est destinée à former une liaison avec la feuille rigide à emballer, ici le pare-brise. Elle est choisie de telle façon que la résistance aux efforts de cisaillement de la liaison soit suffisante pour que le pare-brise reste suspendu au moyen de liaison 9, en position verticale, mais que, de préférence, le pare-brise puisse être décollé des éléments 15a, 15b et 15c par l'effort d'un opérateur, sans que cela ne lui laisse de traces. Un tel adhésif est par exemple semblable à ceux qui sont collés sur les carrosseries des voitures neuves pour les protéger mais peuvent être décollés sans abîmer la peinture.With reference to Figures 3 and 4 the adhesive connecting means 9 is in the form here of three elements 15a, 15b and 15c in the form of ribbons or strips parallel to each other, and arranged vertically at a distance from each other. In the embodiment shown, the rectangle formed at a height at least twice as large as the width. On a first face, the front face, the elements 15a, 15b and 15c are coated uniformly with a coating of a first adhesive material 16a, 16b, 16c. This adhesive material is intended to form a bond with the rigid sheet to be wrapped, here the windshield. It is chosen such that the resistance to the shearing forces of the connection is sufficient so that the windshield remains suspended from the connecting means 9, in the vertical position, but that, preferably, the windshield can be detached from the elements 15a, 15b and 15c by the effort of an operator, without this leaving him any traces. Such an adhesive is for example similar to those which are stuck on the bodies of new cars to protect them but can be peeled without damaging the paint.

Les éléments 15a, 15b, 15c du moyen de liaison 9 comprennent, sur la face opposée, la face arrière, une deuxième matière adhésive 18a, 18b, 18c. Il peut s'agir des bandes adhésives 18a, 18b, 18c à double face adhésive, une face étant collée sur l'élément correspondant 15a, 15b et 15c et l'autre étant destinée à être collée, selon une liaison forte, au panneau central 6 de la plaque 1. Ces bandes 18a, 18b, 18c peuvent également être obtenues par application d'une colle à chaud sur les éléments.The elements 15a, 15b, 15c of the connecting means 9 comprise, on the opposite face, the rear face, a second adhesive material 18a, 18b, 18c. It may be adhesive tapes 18a, 18b, 18c with double-sided adhesive, one face being bonded to the corresponding element 15a, 15b and 15c and the other being intended to be bonded, in a strong connection, to the central panel 6 of the plate 1. These strips 18a, 18b, 18c can also be obtained by applying a hot glue on the elements.

Conformément à une caractéristique de l'invention les éléments 15a, 15b et 15c sont découpés dans une feuille d'une mousse résiliente telle qu'un mousse de polyéthylène ou de polyuréthane. Ce type de mousse est en soi déjà connu et disponible comme rembourrage dans le domaine de l'emballage. On choisit les dimensions et le nombre des éléments de manière expérimentale en fonction du résultat à obtenir qui est la tenue aux chocs verticaux en particulier.According to a feature of the invention the elements 15a, 15b and 15c are cut from a sheet of a resilient foam such as a polyethylene foam or polyurethane. This type of foam is in itself already known and available as padding in the field of packaging. The dimensions and the number of elements are chosen experimentally as a function of the result to be obtained, which is the resistance to vertical shocks in particular.

Par exemple, le matériau susceptible d'être utilisé est un double adhésif en mousse de polyéthylène d'épaisseur 1100 µm, avec une masse adhésive en acrylique : allongement à la rupture >200%, charge de rupture > 9N/15 mm et résistance à une température de 80°C. La masse adhésive est par exemple un élastomère de synthèse d'épaisseur de 0,08 mm avec un allongement >450%, une charge à la rupture >20N/mm2 et un pouvoir adhésif de 1N/cm.For example, the material that can be used is a double adhesive made of 1100 μm thick polyethylene foam, with an acrylic adhesive mass: elongation at break> 200%, breaking load> 9N / 15 mm and resistance to a temperature of 80 ° C. The adhesive mass is, for example, a synthetic elastomer with a thickness of 0.08 mm with a elongation> 450%, a breaking load> 20N / mm 2 and an adhesive strength of 1N / cm.

La plaque 1 comprend deux découpes 20, 21 de forme ovale chevauchant horizontalement les doubles raines verticales (4, 4'), (5, 5'), à une altitude correspondant environ aux deux tiers de leur hauteur. Chaque découpe 20, 21 est symétrique par rapport à la double raine (4, 4'), (5, 5') qu'elle chevauche et les deux découpes 20, 21 sont symétriques l'une de l'autre par rapport à un axe central vertical du panneau central 6.The plate 1 comprises two oval-shaped cutouts 20, 21 horizontally overlapping the double vertical rakes (4, 4 '), (5, 5'), at an altitude corresponding to approximately two-thirds of their height. Each cutout 20, 21 is symmetrical with respect to the double groove (4, 4 '), (5, 5') that it overlaps and the two cuts 20, 21 are symmetrical to one another with respect to a vertical central axis of the central panel 6.

Chaque panneau latéral 7, 8 comprend une découpe 22, 23, respectivement, destinée à coopérer avec une languette correspondante 24, 25, respectivement, située sur le panneau inférieur 10, lorsqu'une feuille rigide est emballée, comme on le verra plus loin.Each side panel 7, 8 comprises a cutout 22, 23, respectively, intended to cooperate with a corresponding tongue 24, 25, respectively, located on the lower panel 10, when a rigid sheet is packaged, as will be seen later.

Le procédé de mise en place d'un emballage d'une feuille rigide de l'invention va maintenant être décrit plus en détails, en référence aux figures 1, 2 et 5.The method of placing a rigid sheet package of the invention will now be described in more detail with reference to Figures 1, 2 and 5 .

La plaque 1 est mise à plat. On met en place les éléments 15a, 15b et 15c par les bandes adhésives 18a, 18b, 18c de leur face arrière, au centre du panneau central 6 de la plaque 1. On place ces éléments de façon que leurs bords latéraux soient parallèles aux raines 12 du panneau central 6.Plate 1 is laid flat. The elements 15a, 15b and 15c are put in place by the adhesive strips 18a, 18b, 18c of their rear face, in the center of the central panel 6 of the plate 1. These elements are placed so that their lateral edges are parallel to the grooves 12 of the central panel 6.

Si l'enduction 16a, 16b, 16c de la face avant des éléments était protégée par une pellicule de protection, on enlève cette dernière. On dépose un pare-brise 26 à emballer sur la plaque, de façon à ce que son bord inférieur 27 s'étende le long de la raine supérieure 11 de la double raine horizontale (11, 11') du panneau central 6 et que ses bords latéraux 28, 29 s'étendent le long des raines intérieures 4, 5, respectivement, des doubles raines verticales (4, 4'), (5, 5') des panneaux latéraux 7, 8. Son bord supérieur 30 est situé à l'intérieur du panneau central 6, espacé du bord supérieur 3 de ce dernier. Le bord inférieur 27 du pare-brise 26 peut avantageusement s'étendre au-dessus de la raine horizontale supérieure 11, espacés vers le haut de cette dernière ; les avantages de cette configuration seront vus plus loin.If the coating 16a, 16b, 16c of the front face of the elements was protected by a protective film, the latter is removed. A windshield 26 is deposited on the plate, so that its lower edge 27 extends along the upper groove 11 of the horizontal double groove (11, 11 ') of the central panel 6 and that its side edges 28, 29 extend along the inner rims 4, 5, respectively, of the vertical double raines (4, 4 '), (5, 5') of the side panels 7, 8. Its upper edge 30 is located at the inside of the central panel 6, spaced from the upper edge 3 of the latter. The lower edge 27 of the windshield 26 can advantageously extend above the upper horizontal rim 11, spaced upwards thereof; the advantages of this configuration will be seen later.

On replie les panneaux latéraux 7, 8, le long des doubles raines verticales (4, 4'), (5, 5'), sur le pare-brise 26. La surface de largeur "e" entre les raines des doubles raines verticales (4, 4'), (5, 5') permet d'envelopper l'épaisseur du pare-brise 26.The side panels 7, 8 are folded along the vertical double rolls (4, 4 '), (5, 5'), on the windshield 26. The width surface "e" between the grooves of the vertical double rolls (4, 4 '), (5, 5') makes it possible to wrap the thickness of the windshield 26.

Si le pare-brise 26 est galbé, ce qui est le plus souvent le cas, la plaque 1 se déforme autour des raines verticales 12 et sa surface vient au contact de celle du pare-brise 26. On appuie alors dans la région des éléments du moyen de liaison 9 pour former la liaison entre le pare-brise 26 et la plaque 1, par le biais de l'enduction de matière adhésive.If the windshield 26 is curved, which is most often the case, the plate 1 is deformed around the vertical raines 12 and its surface comes into contact with that of the windshield 26. It is then supported in the region of the elements. connecting means 9 to form the connection between the windshield 26 and the plate 1, through the coating of adhesive material.

On replie le panneau inférieur 10, le long de la double raine (11, 11'), sur les panneaux latéraux 7, 8 et le pare-brise 26, la surface de largeur "e" entre les raines 11, 11' permettant d'envelopper l'épaisseur du pare-brise 26. Ce faisant, les découpes 14, 14' pivotent autour de la double raine horizontale (11, 11') du panneau central 6. Le deuxième segment horizontal 14c de la découpe gauche 14 se retrouve alors, d'après les dimensions précédemment évoquées (notamment les deux dimensions h), au niveau du bord inférieur 7' du panneau latéral gauche 7. Il en va de même du côté droit, par symétrie.The lower panel 10 is folded along the double groove (11, 11 '), on the side panels 7, 8 and the windshield 26, the area of width "e" between the raines 11, 11' allowing Wrap the thickness of the windshield 26. In doing so, the cutouts 14, 14 'are pivoted around the horizontal double groove (11, 11') of the central panel 6. The second horizontal segment 14c of the left cut 14 is found then, according to the previously mentioned dimensions (including the two dimensions h), at the lower edge 7 'of the left side panel 7. The same is true of the right side, by symmetry.

En référence à la figure 5, la plaque 1 comprend alors un bord de contention du bord inférieur du pare-brise 26, constitué de la surface entre les deux raines horizontales 11, 11', de largeur e. Il n'y a avantageusement pas contact entre ces deux bords, comme on l'a annoncé plus haut. En dessous de cette surface, la plaque 1 présente deux pieds 31, 32, constitués par la partie basse des panneaux latéraux 7, 8 et les surfaces du panneau central 6, situées entre les découpes 14, 14', qui ont pivoté lorsque l'on a replié le panneau inférieur 10. Ces pieds 31, 32 présentent donc une garde au sol d'une hauteur h.With reference to the figure 5 , the plate 1 then comprises a compression edge of the lower edge of the windshield 26, consisting of the surface between the two horizontal raines 11, 11 ', of width e. There is advantageously no contact between these two edges, as announced above. Below this surface, the plate 1 has two feet 31, 32, constituted by the lower part of the side panels 7, 8 and the surfaces of the central panel 6, located between the cutouts 14, 14 ', which have pivoted when the the bottom panel 10 has been folded up. These feet 31, 32 thus have a ground clearance of a height h.

On rentre les languettes 24, 25 du panneau inférieur 10 dans les découpes 22, 23 des panneaux latéraux 7, 8 afin d'assurer le verrouillage de l'ensemble. Les positions respectives des languettes 24, 25 et des découpes 22, 23 ont été agencées de façon à ce que ces éléments se trouvent en face les uns des autres une fois l'emballage dans cette configuration repliée. Il va de soi que les languettes pourraient être agencées sur les panneaux latéraux 7, 8 et les découpes sur le panneau inférieur 10, l'objectif étant quoi qu'il en soit d'obtenir un système de verrouillage du panneau inférieur 10 sur les panneaux latéraux 7, 8.The tabs 24, 25 of the bottom panel 10 are tucked into the recesses 22, 23 of the side panels 7, 8 to lock the assembly. The respective positions of the tongues 24, 25 and cutouts 22, 23 have been arranged so that these elements face each other once the packaging in this folded configuration. It goes without saying that the tabs could be arranged on the side panels 7, 8 and the cutouts on the bottom panel 10, the objective being anyway to obtain a locking system of the lower panel 10 on the panels lateral 7, 8.

Les découpes 20, 21 qui chevauchaient les doubles raines verticales (4, 4'), (5, 5') forment, une fois l'emballage formé, des poignées de préhension de part et d'autre de l'emballage.The cutouts 20, 21 which overlapped the double vertical raines (4, 4 '), (5, 5') form, once the package is formed, grip handles on either side of the package.

Une fois la plaque 1 et le pare-brise 26 ainsi assemblés, on présente l'ensemble à un poste d'enveloppage, non représenté. Il comporte des moyens pour envelopper l'ensemble d'une pellicule de matériau thermo-rétractable. Ce dernier, en passant sous un flux d'air chaud approprié, s'échauffe jusqu'à la température où il se rétracte. L'enveloppe ainsi formée assure une protection de l'ensemble, et exerce également une pression sur ce dernier, afin de contraindre le pare-brise 26 à rester collé à la plaque 1 et le panneau inférieur 10 à rester solidaire des panneaux latéraux 7, 8, le verrouillage par les languettes 24, 25 et les découpes 22, 23 étant de cette façon complété et assuré.Once the plate 1 and the windshield 26 thus assembled, the assembly is presented to a wrapping station, not shown. It comprises means for wrapping the entire film of heat-shrinkable material. The latter, under a flow of appropriate hot air, heats to the temperature where it retracts. The casing thus formed provides protection of the assembly, and also exerts pressure on the latter, in order to constrain the windshield 26 to remain stuck to the plate 1 and the lower panel 10 to remain attached to the side panels 7, 8, the locking by the tabs 24, 25 and the cutouts 22, 23 being thereby completed and ensured.

L'emballage du pare-brise 26 ainsi formé permet, non seulement de conditionner le pare-brise 26, et de le poser sur les pieds 31, 32 verticalement, mais aussi d'assurer un amortissement des efforts en cas de chute verticale. En effet, supposons que l'emballage, en position verticale, chute verticalement. Il atterrit sur les pieds 31, 32, qui absorbent une partie des efforts, par compression des diverses surfaces du carton qui les composent. En outre, le pare-brise 26 peut avoir été, volontairement, positionné à une altitude supérieure sur le panneau central 6, de façon à ce que son bord inférieur 27 ne soit pas en contact avec la surface située entre les raines horizontales 11, 11'. Cela est réalisable car l'enduction de matière adhésive sur la face avant des éléments 15a, 15b 15c, assure la suspension du pare-brise 26 sur le panneau central 6. Le choc tend à faire glisser le pare-brise 26 vers le bas. Les éléments 15a, 15b et 15c peuvent se déformer et contribuer à absorber les efforts transmis à l'emballage du fait de la chute sans qu'il se produise un décrochage du pare-brise du moyen de liaison adhésifThe packaging of the windshield 26 thus formed makes it possible not only to condition the windshield 26 and to place it on the feet 31, 32 vertically, but also to ensure damping of the forces in the event of a vertical fall. Indeed, suppose that the packaging, in vertical position, falls vertically. It lands on the feet 31, 32, which absorb some of the forces, by compression of the various surfaces of the cardboard that compose them. In addition, the windshield 26 may have been voluntarily positioned at a higher altitude on the central panel 6, so that its lower edge 27 does not come into contact with the surface between the horizontal raines 11, 11 . This is feasible because the adhesive coating on the front of the elements 15a, 15b 15c ensures the suspension of the windshield 26 on the central panel 6. The shock tends to slide the windshield 26 down. The elements 15a, 15b and 15c can be deformed and contribute to absorbing the forces transmitted to the packaging due to the fall without a stall of the windshield of the adhesive connection means.

L'emballage de l'invention est dimensionné de façon à pouvoir assumer, sans détérioration du pare-brise 26, trois à quatre chutes d'une trentaine de centimètres d'altitude, pour un pare-brise pesant 10 à 50 kg. Comme on l'a vu, l'amortissement est assuré par les pieds 31, 32 essentiellement et dans une certaine mesure par le matériau mousse constituant les éléments du moyen de liaison adhésifThe packaging of the invention is dimensioned so as to assume, without damaging the windshield 26, three to four falls of about thirty centimeters in altitude, for a windshield weighing 10 to 50 kg. As we have seen, the damping is provided by the feet 31, 32 essentially and to some extent by the foam material constituting the elements of the adhesive connection means

Il est en outre possible de faire rouler l'emballage le long des ses faces - en passant d'une face à l'autre - car la liaison adhésive entre le panneau central 6 et le pare-brise 26 est suffisamment forte pour conserver le pare-brise en suspension sur le panneau central 6 lors d'une telle opération, notamment lorsque c'est le bord supérieur 3 de la plaque 1 qui vient sur le sol. Une chute sur le bord supérieur 3 ne pourrait toutefois pas être amortie aussi efficacement, car ce dernier ne comprend pas de pieds d'amortissement.It is also possible to roll the package along its faces - from one side to another - because the adhesive connection between the central panel 6 and the windshield 26 is strong enough to keep the screen -brise suspended on the central panel 6 during such an operation, especially when it is the upper edge 3 of the plate 1 which comes on the ground. A fall on the upper edge 3, however, could not be damped so effectively because the latter does not include damping feet.

Avantageusement, le carton ondulé est choisi de façon à ce que ses cannelures soient plus légères que les feuilles de couvertures. On peut par exemple choisir des cannelures de 105 g/m2 et des feuilles de couverture de plus de 200 g/m2. Le carton offre ainsi une meilleure résistance aux efforts d'arrachement, ce qui est important, notamment, pour les languettes 24, 25. Le carton doit en outre pouvoir se déformer - pour absorber les chutes verticales - tout en présentant une résistance suffisante aux déchirures.Advantageously, the corrugated cardboard is chosen so that its flutes are lighter than the sheets of blankets. For example, splines of 105 g / m 2 and cover sheets of more than 200 g / m 2 can be selected. The cardboard thus offers a better resistance to tearing forces, which is important, in particular, for the tongues 24, 25. The cardboard must also be able to deform - to absorb the vertical drops - while having a sufficient resistance to tearing .
