Un véhicule automobile est couramment équipé d'un système d'essuie-glace pour assurer un essuyage du pare-brise et éviter que la vision qu'a le conducteur de son environnement ne soit perturbée. Un tel système comprend généralement un ou deux balais d'essuie-glace qui portent des lames d'essuyage réalisées en une matière élastique. Ces lames, positionnées pour l'une devant le conducteur et pour l'autre devant le passager, frottent contre le pare-brise et évacuent l'eau en l'amenant en dehors de leur champ de vision.A motor vehicle is commonly equipped with a wiper system to wipe the windshield and prevent the driver's vision from being disturbed. Such a system generally comprises one or two wiper blades which carry wiper blades made of an elastic material. These blades, positioned for one in front of the driver and the other in front of the passenger, rub against the windshield and evacuate the water by bringing it out of their field of vision.

Il existe aujourd'hui une nouvelle génération de balais d'essuie-glace dont la particularité est d'être dépourvue de structures à palonniers, contrairement aux balais à lame droite communément employés. Ce nouveau type de balai, appelé balai plat ou « flat bade », dispose toujours d'une lame racleuse souple, mais l'armature externe chargée de la supporter est ici remplacée par une structure flexible qui est directement intégrée à la lame. L'ensemble est agencé de manière à ce qu'au repos, la lame présente longitudinalement une forme concave dans son plan sagittal, mais qu'au contact d'une surface à essuyer, ladite lame soit en mesure de se redresser par déformation élastique de sa structure flexible afin d'épouser au mieux ladite surface tout au long de son déplacement.Today, there is a new generation of wiper blades that have the characteristic of being devoid of pedals, unlike standard straight blade brooms. This new type of broom, called flat blade or "flat bade", still has a flexible scraper blade, but the outer frame responsible for the support is here replaced by a flexible structure that is directly integrated with the blade. The assembly is arranged so that at rest, the blade longitudinally has a concave shape in its sagittal plane, but that on contact with a surface to be wiped, said blade is able to straighten by elastic deformation of its flexible structure to better marry said surface throughout its movement.

Du fait précisément de sa forme incurvée, un tel balai d'essuie-glace à lame courbe peut présenter au repos un encombrement bien supérieur à son homologue à structure à palonniers et lame droite. Il est ainsi souhaitable d'utiliser un dispositif d'emballage de forme allongée qui permet de redresser le balai dans une position droite de manière à réduire l'encombrement du balai.Because of its curved shape, such a wiper blade curved blade can have a rest at a much greater congestion than its pedestal counterweight and straight blade. It is thus desirable to use an elongated packaging device which allows the brush to be straightened in a straight position so as to reduce the bulk of the brush.

Tel qu'il est décrit dans le brevet US 8'434'621 B2 , il est connu à cet effet d'utiliser pour la fabrication du dispositif d'emballage un flan comprenant deux zones longitudinales adjacentes articulables entre elles via une ligne de pliage longitudinale, chaque zone longitudinale étant destinée à former une face longitudinale du dispositif d'emballage. Au moins une des zones longitudinales est en outre articulée à chacune de ses extrémités longitudinales à une zone d'extrémité, via une ligne de pliage transversale. Chaque zone d'extrémité est apte à former une face d'extrémité sensiblement transversale du dispositif d'emballage. Le dispositif d'emballage est alors fabriqué en pliant le flan le long de la ligne, puis en solidarisant les zones longitudinales, par exemple à l'aide d'un rabat longitudinal adhésif relié à l'une des faces longitudinales, de manière à former un contour transversalement fermé comprenant les faces longitudinales du dispositif d'emballage. La fabrication du dispositif d'emballage s'achève en rabattant par pliage les zones d'extrémité du flan en direction du contour transversalement fermé, de manière à former les faces d'extrémité transversales du dispositif d'emballage.As described in the patent US 8,434,621 B2 , it is known for this purpose to use for the manufacture of the packaging device a blank comprising two adjacent longitudinal zones articulatable to each other via a longitudinal fold line, each longitudinal zone being intended to form a longitudinal face of the packaging device . At least one of the longitudinal zones is further articulated at each of its longitudinal ends to an end zone, via a transverse fold line. Each end zone is able to form a substantially transverse end face of the packaging device. The packaging device is then manufactured by folding the blank along the line, then by joining the longitudinal zones, for example by means of an adhesive longitudinal flap connected to one of the longitudinal faces, so as to form a transversely closed contour comprising the longitudinal sides of the packaging device. The manufacture of the packaging device is completed by fold folding the end zones of the blank towards the transversely closed contour, so as to form the transverse end faces of the packaging device.

Un dispositif d'emballage fabriqué à partir d'un tel flan a pour inconvénient d'être fragile vis-à-vis d'un impact extérieur. En particulier, lors d'une chute du dispositif d'emballage ou d'un choc du dispositif avec un objet extérieur, spécialement au niveau des extrémités longitudinales du dispositif, il y a un risque de rupture du dispositif d'emballage et le balai peut être endommagé.A packaging device made from such a blank has the disadvantage of being fragile vis-à-vis an external impact. In particular, during a fall of the packaging device or a shock of the device with an external object, especially at the longitudinal ends of the device, there is a risk of rupture of the packaging device and the broom may be damaged.

La présente invention vise à remédier à ces inconvénients, en proposant un flan pour la fabrication d'un dispositif d'emballage adapté en particulier à l'emballage de balai(s) d'essuie-glace à lame courbe, mais également à l'emballage de balai(s) d'essuie-glace à palonniers, ledit flan permettant de fabriquer un dispositif d'emballage présentant une bonne résistance aux chocs, en particulier aux chocs subis au niveau d'une extrémité transversale du dispositif, typiquement lors d'une chute du dispositif d'emballage.The present invention aims to remedy these drawbacks, by proposing a blank for the manufacture of a packaging device adapted in particular to the wrapping of wiper blade (s) curved blade, but also to the wrapping wiper blade (s) with rudder, said blank for manufacturing a packaging device having good impact resistance, in particular shocks suffered at a transverse end of the device, typically when a fall of the packaging device.

L'invention a ainsi pour objet un flan pour la fabrication d'un dispositif d'emballage d'au moins un balai d'essuie-glace, ledit flan étant de forme allongée et comprenant au moins deux zones longitudinales adjacentes articulables entre elles via une ligne de pliage longitudinale, chaque zone longitudinale étant destinée à former une face longitudinale du dispositif d'emballage, au moins une des zones longitudinales étant en outre articulée à chacune de ses extrémités longitudinales à une zone d'extrémité, via une ligne de pliage transversale, chaque zone d'extrémité étant apte à former une face d'extrémité sensiblement transversale du dispositif d'emballage.The subject of the invention is thus a blank for the manufacture of a device for packaging at least one wiper blade, said blank being of elongate shape and comprising at least two adjacent longitudinal zones articulable to one another via a longitudinal fold line, each longitudinal zone being intended to form a longitudinal face of the packaging device, at least one of the longitudinal zones being further articulated at each of its longitudinal ends to an end zone, via a transverse fold line each end region being adapted to form a substantially transverse end face of the packaging device.

Le flan selon l'invention comprend, du côté de chacune de ses extrémités longitudinales, des moyens d'amortissement longitudinal, situés au niveau de la ligne de pliage longitudinale, et écartés longitudinalement et/ou s'étendant jusqu'à un point écarté longitudinalement de la ou des lignes de pliage transversale(s) de l'extrémité longitudinale correspondante du flan, lesdits moyens d'amortissement comprennent une ou plusieurs fentes, orifices, rainures et/ou encoches.The blank according to the invention comprises, on the side of each of its longitudinal ends, longitudinal damping means located at the level of the longitudinal fold line, and spaced apart longitudinally and / or extending to a longitudinally spaced point. of the transverse folding line (s) of the corresponding longitudinal end of the blank, said damping means comprise one or more slots, orifices, grooves and / or notches.

Dans la présente invention, on entend par moyens d'amortissement des moyens configurés pour atténuer les effets d'un choc, en particulier en cas de chute. Ils peuvent être configurés pour absorber une partie des efforts résultants du choc, par exemple en autorisant une déformation élastique et/ou plastique du dispositif. Ils peuvent par exemple être conçus pour se déformer par écartement ou compression d'une partie du dispositif. Ils peuvent être formés par amincissement, affaiblissement ou évidement localisé du flan.In the present invention, the term damping means means configured to mitigate the effects of an impact, particularly in case of a fall. They can be configured to absorb a part of the forces resulting from the shock, for example by allowing an elastic and / or plastic deformation of the device. They may for example be designed to deform by spacing or compression of a part of the device. They can be formed by thinning, weakening or localized recess of the blank.

Ainsi, avantageusement, la présence de ces moyens d'amortissement permet une déformation longitudinale du dispositif d'emballage sous l'effet d'un impact extérieur, ce qui réduit fortement les risques de rupture du dispositif d'emballage.Thus, advantageously, the presence of these damping means allows longitudinal deformation of the packaging device under the effect of an external impact, which greatly reduces the risk of rupture of the packaging device.

Les moyens d'amortissement sont de préférence situés sur la ligne de pliage longitudinale.The damping means are preferably located on the longitudinal fold line.

Les moyens d'amortissement peuvent en particulier être disposés au moins en partie au-delà d'un plan transversal de jonction sensiblement orthogonal à la ligne de pliage longitudinale et passant sensiblement par les extrémités transversales de la ou des lignes de pliage transversale(s) de l'extrémité longitudinale correspondante du flan, i.e. de la ou des lignes de pliage transversale(s) située(s) du côté desdits moyens d'amortissement et adjacente(s) à la ligne de pliage longitudinale. Les moyens d'amortissement peuvent en particulier s'étendre depuis une extrémité longitudinale du flan et au-delà du plan transversal de jonction. Ils peuvent également être disposés dans une zone d'extrémité longitudinale du flan, par exemple à proximité d'une extrémité longitudinale du flan, et à distance du plan transversal de jonction.The damping means may in particular be arranged at least partly beyond a transverse junction plane substantially orthogonal to the longitudinal fold line and passing substantially through the transverse ends of the transverse fold line (s) of the corresponding longitudinal end of the blank, ie of the transverse folding line (s) located on the side of said adjacent damping means (s) at the longitudinal fold line. The damping means may in particular extend from a longitudinal end of the blank and beyond the transverse junction plane. They may also be arranged in a longitudinal end zone of the blank, for example near a longitudinal end of the blank, and away from the transverse junction plane.

Chaque zone longitudinale peut être articulée à chacune de ses extrémités longitudinales à une zone d'extrémité, via une ligne de pliage transversale.Each longitudinal zone can be articulated at each of its longitudinal ends to an end zone, via a transverse fold line.

Conformément à un premier mode de réalisation, les moyens d'amortissement comprennent au moins une fente qui s'étend depuis une ou chaque extrémité longitudinale du flan, le long de la ligne de pliage longitudinale, et au-delà d'un plan transversal de jonction sensiblement orthogonal à la ligne de pliage longitudinale et passant sensiblement par les extrémités transversales de la ou des lignes de pliage transversale(s) de l'extrémité longitudinale correspondante du flan.According to a first embodiment, the damping means comprise at least one slot which extends from one or each longitudinal end of the blank, along the longitudinal fold line, and beyond a transverse plane of the blank. junction substantially orthogonal to the longitudinal fold line and passing substantially through the transverse ends of the transverse folding line or lines (s) of the corresponding longitudinal end of the blank.

La ou chaque fente peut présenter un contour périphérique en forme de U, de C, de V ou de O.The or each slot may have a peripheral contour in the form of U, C, V or O.

Une fente peut s'étendre sur la ligne de pliage longitudinale depuis chaque extrémité longitudinale du flan.A slot may extend over the longitudinal fold line from each longitudinal end of the blank.

Une des zones longitudinales peut être articulée via une autre ligne de pliage longitudinale à un rabat longitudinal, et au moins une fente peut s'étendre sur ladite autre ligne de pliage longitudinale, depuis une ou chaque extrémité longitudinale du flan, et au-delà d'un plan transversal de jonction sensiblement orthogonal à ladite autre ligne de pliage et passant sensiblement par les extrémités transversales de la ligne de pliage transversale de l'extrémité longitudinale correspondante du flan.One of the longitudinal zones can be articulated via another longitudinal fold line to a longitudinal flap, and at least one slot can extend on said other longitudinal fold line, from one or each longitudinal end of the blank, and beyond a transverse junction plane substantially orthogonal to said other fold line and passing substantially through the transverse ends of the transverse fold line of the corresponding longitudinal end of the blank.

Conformément à un deuxième mode de réalisation, les moyens d'amortissement comprennent, du côté d'une ou de chaque extrémité longitudinale du flan, au moins un orifice situé sur la ligne de pliage longitudinale et à distance d'un plan transversal de jonction sensiblement orthogonal à la ligne de pliage longitudinale et passant sensiblement par les extrémités transversales de la ou des lignes de pliage transversale(s) de l'extrémité longitudinale correspondante du flan.According to a second embodiment, the damping means comprise, on the side of one or each longitudinal end of the blank, at least one orifice situated on the longitudinal fold line and at a distance from a transverse junction plane substantially orthogonal to the longitudinal fold line and passing substantially through the transverse ends of the transverse fold line (s) of the corresponding longitudinal end of the blank.

La ou chaque ligne de pliage longitudinale peut comprendre deux, quatre ou six orifices d'amortissement.The or each longitudinal fold line may comprise two, four or six damping orifices.

L'orifice, ou chaque orifice, peut être de section circulaire, ovale, rectangulaire ou carrée.The orifice, or each orifice, may be of circular, oval, rectangular or square section.

Au moins une des rainures peut déboucher sur une face longitudinale externe d'une ou de plusieurs zone(s) longitudinale(s).At least one of the grooves may open on an outer longitudinal face of one or more longitudinal zone (s).

Chaque orifice peut être relié à une unique rainure située d'un seul côté de la ligne de pliage longitudinale, sur une zone longitudinale, ou à deux rainures situées de part et d'autre de l'orifice, sur deux zones longitudinales.Each orifice may be connected to a single groove located on one side of the longitudinal fold line, on a longitudinal zone, or with two grooves located on either side of the orifice, on two longitudinal zones.

Le flan peut être réalisé en un matériau plastique, de préférence transparent ou translucide, et de préférence en un matériau plastique rigide. Le matériau peut ainsi être choisi parmi le poly(téréphtalate d'éthylène) (couramment appelé PET), le poly(chlorure de vinyle) (PVC) ou encore le polypropylène (PP). Le flan peut également être réalisé en carton.The blank can be made of a plastic material, preferably transparent or translucent, and preferably a rigid plastic material. The material may thus be chosen from polyethylene terephthalate (commonly called PET), polyvinyl chloride (PVC) or polypropylene (PP). The blank can also be made of cardboard.

Lesdites au moins deux zones longitudinales peuvent comprendre des ouvertures configurées de manière à ce qu'elles forment après fabrication du dispositif d'emballage un passage pour un élément d'accroché du dispositif d'emballage.

The openings are for example in the form of "European holes" or any other form allowing the passage of the hooked element.

Le flan peut comprendre uniquement deux zones longitudinales.The blank can comprise only two longitudinal zones.

Les lignes de pliage transversales peuvent avoir une forme incurvée dont les convexités sont orientées l'une vers l'autre, de manière à ce que le dispositif d'emballage présente après fabrication deux faces longitudinales incurvées convexes et deux faces transversales incurvées concaves.The transverse fold lines may have a curved shape whose convexities are oriented toward each other, so that the packaging device has after manufacture two convex curved longitudinal faces and two concave curved transverse faces.

Tel qu'illustré à la figure 1, un flan 1 selon l'invention pour la fabrication d'un dispositif d'emballage d'au moins un balai d'essuie-glace comprend au moins deux zones longitudinales 2, 3 articulées entre elles par une ligne de pliage longitudinale 4. A titre d'exemple, la figure 1 montre un flan muni de seulement deux zones longitudinales 2, 3, ce qui conduira à la fabrication d'un dispositif d'emballage muni de deux faces latérales longitudinales, par exemple une face avant 2' et une face arrière 3' reliées par des arêtes 4' et 10' (figure 7). On peut toutefois concevoir un flan d'emballage 1 comprenant plus de deux zones longitudinales, la pluralité de zones longitudinales définissant alors pour le dispositif d'emballage une fois fabriqué un profil longitudinal polygonal.As illustrated in figure 1 , a blank 1 according to the invention for the manufacture of a device for packaging at least one wiper blade comprises at least two longitudinal zones 2, 3 hinged together by a longitudinal fold line 4. A For example, figure 1 shows a blank provided with only two longitudinal zones 2, 3, which will lead to the manufacture of a packaging device provided with two longitudinal lateral faces, for example a front face 2 'and a rear face 3' connected by edges 4 'and 10' ( figure 7 ). However, it is conceivable to design a packaging blank 1 comprising more than two longitudinal zones, the plurality of longitudinal zones then defining for the packaging device once manufactured a polygonal longitudinal profile.

Au moins une zone longitudinale 2, 3, et de préférence les deux, est articulée à chacune de ses extrémités longitudinales à une zone d'extrémité 21, 22; 31, 32, via une ligne de pliage transversale 5, 6; 7, 8, à savoir deux zones d'extrémités supérieures 21, 31 et deux zones d'extrémité inférieures 22, 32. Les deux zones d'extrémité supérieures 21, 31 sont destinées à former une face d'extrémité sensiblement transversale du dispositif d'emballage, les deux zones d'extrémité inférieures 22, 32 étant destinées à former l'autre face d'extrémité sensiblement transversale du dispositif d'emballage.At least one longitudinal zone 2, 3, and preferably both, is articulated at each of its longitudinal ends to an end zone 21, 22; 31, 32, via a transverse fold line 5, 6; 7, 8, namely two upper end regions 21, 31 and two lower end zones 22, 32. The two upper end zones 21, 31 are intended to form a substantially transverse end face of the end device. packaging, the two lower end zones 22, 32 being intended to form the other substantially transverse end face of the packaging device.

Les lignes de pliage transversales 5, 6, 7, 8 peuvent être courbes, notamment en forme d'arc de cercle, et leurs convexités peuvent être orientées l'une vers l'autre, de manière à ce que le dispositif d'emballage présente après fabrication des faces longitudinales avant 2' et 3' incurvées convexes et deux faces transversales 21', 31' incurvées concaves (figure 7).The transverse fold lines 5, 6, 7, 8 may be curved, in particular in the shape of an arc of a circle, and their convexities may be oriented towards each other, so that the packaging device has after manufacture of the longitudinal front faces 2 'and 3' convex curved and two transverse faces 21 ', 31' concave curved ( figure 7 ).

Chaque zone longitudinale 2,3 peut comprendre dans sa partie supérieure une ouverture 2A, 3A, de manière à ce que les ouvertures 2A, 3A forment après fabrication du dispositif d'emballage un passage 2A' pour un élément d'accroché du dispositif d'emballage (figure 7).Each longitudinal zone 2,3 may comprise in its upper part an opening 2A, 3A, so that the openings 2A, 3A form after manufacture of the packaging device a passage 2A 'for a hooking element of the device. packaging ( figure 7 ).

Le flan 1 comprend avantageusement un rabat longitudinal 9 qui est adjacent à une zone longitudinale 2 et qui est articulé via une deuxième ligne de pliage longitudinale 10 à cette zone longitudinale 2. Les lignes de pliage longitudinales 4, 10 sont ici sensiblement parallèles.The blank 1 advantageously comprises a longitudinal flap 9 which is adjacent to a longitudinal zone 2 and which is articulated via a second longitudinal fold line 10 to this longitudinal zone 2. The longitudinal fold lines 4, 10 are here substantially parallel.

La zone longitudinale 2 est bordée par les lignes de pliage transversales 4, 5, 6, 10 qui lui imposent sa forme, et la zone longitudinale 3 est bordée par les lignes de pliage 4, 7, 8, ainsi que par une bordure longitudinale libre 13. Les zones longitudinales 2, 3 ont globalement la même forme. Les zones d'extrémité 21, 22, 31, 32 ont également globalement la même forme.The longitudinal zone 2 is bordered by the transverse fold lines 4, 5, 6, 10 which impose its shape, and the longitudinal zone 3 is bordered by the fold lines 4, 7, 8, as well as by a free longitudinal border 13. The longitudinal zones 2, 3 generally have the same shape. The end zones 21, 22, 31, 32 also have the same overall shape.

Le rabat longitudinal 9 est avantageusement un rabat qui permet lors de la fabrication du dispositif d'emballage de faire adhérer par adhésif, collage, soudage, une face de ce rabat 9 sur une portion d'une face de la zone longitudinale 3, de préférence de sorte que les lignes 10, 13 soient sensiblement confondues. Le dispositif d'emballage présente alors un contour transversalement fermé comprenant les faces longitudinales 2', 3' du dispositif d'emballage.The longitudinal flap 9 is advantageously a flap which allows during the manufacture of the packaging device to adhere by adhesive, bonding, welding, a face of this flap 9 on a portion of a face of the longitudinal zone 3, preferably so that the lines 10, 13 are substantially merged. The packaging device then presents an outline transversely closed comprising the longitudinal faces 2 ', 3' of the packaging device.

Conformément à l'invention, le flan 1 est muni, du côté de chacune de ses extrémités longitudinales, de moyens d'amortissement longitudinal situés au niveau de la ligne de pliage longitudinale 4, et écartés longitudinalement (et/ou s'étendant jusqu'à point écarté longitudinalement) de la ou des lignes de pliage transversale(s) 5, 6, 7, 8 de l'extrémité longitudinale correspondante du flan 1.According to the invention, the blank 1 is provided, on the side of each of its longitudinal ends, with longitudinal damping means located at the level of the longitudinal fold line 4, and spaced longitudinally (and / or extending up to longitudinally spaced) of the transverse folding line (s) 5, 6, 7, 8 of the corresponding longitudinal end of the blank 1.

Dans un premier mode de réalisation, tel qu'illustré sur les figures 1, 2A et 2B, les moyens d'amortissement comprennent une fente 11, traversante ou non, qui s'étend depuis chaque extrémité longitudinale du flan 1, le long de la ligne de pliage longitudinale 4, et au-delà (i.e. du côté des zones longitudinales 2, 3) d'un plan transversal de jonction P sensiblement orthogonal à la ligne de pliage longitudinale 4 et passant sensiblement par les extrémités transversales E des lignes de pliage transversale(s) 5, 6, 7, 8 de l'extrémité longitudinale correspondante du flan 1.In a first embodiment, as illustrated in the Figures 1, 2A and 2B , the damping means comprise a slit 11, passing through or not, which extends from each longitudinal end of the blank 1, along the longitudinal fold line 4, and beyond (ie on the side of the longitudinal zones 2, 3) of a transverse plane of junction P substantially orthogonal to the longitudinal fold line 4 and passing substantially through the transverse ends E of the transverse fold lines (s) 5, 6, 7, 8 of the corresponding longitudinal end of the blank 1.

Ainsi, du côté de l'extrémité supérieure ou haute du flan 1, la fente 11 s'étend le long de la ligne de pliage longitudinale 4 depuis l'extrémité longitudinale supérieure du flan 1 et jusqu'en dessous du plan P sensiblement orthogonal à la ligne de pliage longitudinale 4 et passant sensiblement par les extrémités transversales E des lignes de pliage transversales 5, 7 de l'extrémité supérieure du flan 1 (figure 2A).Thus, on the side of the upper or upper end of the blank 1, the slot 11 extends along the longitudinal fold line 4 from the upper longitudinal end of the blank 1 and below the plane P substantially orthogonal to the longitudinal fold line 4 and passing substantially through the transverse ends E of the transverse fold lines 5, 7 of the upper end of the blank 1 ( Figure 2A ).

De la même façon, du côté de l'extrémité inférieure ou basse du flan 1, la fente 11 s'étend le long de la ligne de pliage longitudinale 4 depuis l'extrémité longitudinale inférieure du flan 1 et jusqu'au-dessus du plan P sensiblement orthogonal à la ligne de pliage longitudinale 4 et passant sensiblement par les extrémités transversales E des lignes de pliage transversales 6, 8 de l'extrémité inférieure du flan 1 (figure 2B).In the same way, on the side of the lower or lower end of the blank 1, the slot 11 extends along the longitudinal fold line 4 from the lower longitudinal end of the blank 1 and to above the plane P substantially orthogonal to the longitudinal fold line 4 and passing substantially through the transverse ends E of the transverse fold lines 6, 8 of the lower end of the blank 1 ( Figure 2B ).

La fente 11 peut présenter différentes formes, et peut notamment présenter un contour périphérique en forme de U, de C, de V ou de O par exemple. La ou chaque fente 11 peut avoir une dimension longitudinale comprise entre 0,5 et 10 mm, et de préférence entre 1 et 5 mm.The slot 11 may have different shapes, and may in particular have a peripheral contour U-shaped, C, V or O for example. The or each slot 11 may have a longitudinal dimension of between 0.5 and 10 mm, and preferably between 1 and 5 mm.

Grâce à la présence des fentes 11, un jeu est créé au niveau des zones d'extrémité 21, 22, 31, 32 du flan 1 et par suite au niveau des faces d'extrémité transversales du dispositif d'emballage, ce qui permet de créer un amortissement au niveau des fentes 11 en cas de choc ou de chute du dispositif d'emballage.Thanks to the presence of the slots 11, a clearance is created at the end zones 21, 22, 31, 32 of the blank 1 and consequently at the level of the transverse end faces of the packaging device, which makes it possible to create a damping at the slots 11 in case of shock or drop of the packaging device.

Les moyens d'amortissement comprennent avantageusement, à au moins une extrémité longitudinale du flan 1, et de préférence aux deux extrémités longitudinales du flan 1, une autre fente 12 s'étendant sur la deuxième ligne de pliage longitudinale 10, depuis une extrémité longitudinale du flan 1, et au-delà du plan transversal de jonction P. On obtient ainsi un meilleur amortissement, car un jeu est disposé à chaque extrémité transversale du flan 1, et par suite à chaque extrémité transversale du dispositif d'emballage. La ou les fentes 12 s'étendant sur la deuxième ligne de pliage longitudinale 10 sont avantageusement de mêmes dimensions longitudinales et transversales que la ou les fentes 11 s'étendant sur la première ligne de pliage longitudinale 10.The damping means advantageously comprise, at at least one longitudinal end of the blank 1, and preferably at the two longitudinal ends of the blank 1, another slot 12 extending on the second longitudinal fold line 10, from a longitudinal end of the blank. blank 1, and beyond the transverse plane of junction P. This provides a better damping, because a game is disposed at each transverse end of the blank 1, and therefore at each transverse end of the packaging device. The slot or slots 12 extending on the second longitudinal fold line 10 are advantageously of the same longitudinal and transverse dimensions as the slot or slots 11 extending on the first longitudinal fold line 10.

Les moyens d'amortissement peuvent également comprendre, sur la bordure longitudinale 13 du flan 1 opposée au rabat longitudinal 9, un évidement (encoche) 14 qui s'étend depuis au moins une extrémité longitudinale du flan 1, et au-delà du plan transversal de jonction P. L'évidement 14 est avantageusement sensiblement de même dimension longitudinale que les fentes 11 et 12, et a sensiblement pour dimension transversale la moitié de la dimension transversale des fentes 11, 12, formant ainsi sensiblement une demi-fente. Lors de la fabrication du dispositif d'emballage, l'évidement 14 vient avantageusement se superposer sur une partie de la fente 12 correspondante située du côté du rabat longitudinal 9 et située à la même hauteur, ce qui contribue à un meilleur amortissement du dispositif d'emballage une fois fabriqué.The damping means may also comprise, on the longitudinal edge 13 of the blank 1 opposite the longitudinal flap 9, a recess (notch) 14 which extends from at least one longitudinal end of the blank 1, and beyond the transverse plane. The recess 14 is advantageously substantially of the same longitudinal dimension as the slits 11 and 12, and has substantially transverse dimension half of the transverse dimension of the slits 11, 12, thus forming substantially a half-slit. During the manufacture of the packaging device, the recess 14 is advantageously superimposed on a portion of the corresponding slot 12 located on the side of the longitudinal flap 9 and located at the same height, which contributes to a better damping of the device. packaging once manufactured.

Dans un deuxième mode de réalisation, qui peut se combiner au premier mode de réalisation, les moyens d'amortissement longitudinal comprennent, dans deux portions d'extrémité longitudinale du flan 1, à savoir une portion d'extrémité supérieure et une portion d'extrémité inférieure du flan 1, au moins un orifice 15, et de préférence plusieurs, situé(s) sur la ligne de pliage longitudinale 4 et à distance du plan transversal de jonction P tel que défini ci-dessus. Le ou les orifices 15 permettent de créer des zones d'amortissement sous la forme de soufflets.In a second embodiment, which can be combined with the first embodiment, the longitudinal damping means comprise, in two longitudinal end portions of the blank 1, namely an upper end portion and an end portion. bottom of the blank 1, at least one orifice 15, and preferably several, located on the fold line longitudinal 4 and away from the transverse plane of junction P as defined above. The orifice (s) 15 make it possible to create damping zones in the form of bellows.

Les moyens d'amortissement comprennent en outre avantageusement au moins un orifice 16, et de préférence plusieurs, situé(s) sur la deuxième ligne de pliage longitudinale 10 et à distance du plan transversal de jonction P. Le ou les orifices 16 sont de préférence situés à même hauteur que le ou les orifices 15 et présentent de préférence les mêmes dimensions longitudinales et transversales.The damping means further advantageously comprise at least one orifice 16, and preferably several, located on the second longitudinal fold line and at a distance from the transverse junction plane P. The orifices 16 are preferably located at the same height as the or openings 15 and preferably have the same longitudinal and transverse dimensions.

Tel qu'illustré sur les figures 3 à 6, les orifices 15, 16 sont de forme circulaire, mais on peut envisager d'autres formes, en particulier des orifices rectangulaires, carrés, ou en forme de losange ou d'ellipse.As illustrated on Figures 3 to 6 the orifices 15, 16 are of circular shape, but other forms may be envisaged, in particular rectangular, square, or diamond-shaped or elliptical orifices.

Les moyens d'amortissement peuvent également comprendre, sur la bordure longitudinale 13 du flan 1 opposée au rabat longitudinal 9, au moins un évidement (encoche) 17, et de préférence plusieurs, situé(s) à distance du plan transversal de jonction P passant par les extrémités transversales de la ligne de pliage transversale 4, et de préférence à même hauteur que le ou les orifices 16 situé(s) sur la deuxième ligne de pliage longitudinale 10. L'évidement 17 est avantageusement sensiblement de même dimension longitudinale que les orifices 15 et 16, et a une dimension transversale sensiblement égale à la moitié de la dimension transversale des orifices 15 et 16, formant ainsi sensiblement un demi-orifice. Lors du pliage du flan 1 pour la fabrication du dispositif d'emballage, l'évidement 17 vient se superposer avec une partie de l'orifice 16 correspondant situé du côté du rabat longitudinal 9 et de même hauteur, ce qui contribue à un meilleur amortissement du dispositif d'emballage une fois fabriqué.The damping means may also comprise, on the longitudinal edge 13 of the blank 1 opposite the longitudinal flap 9, at least one recess (notch) 17, and preferably several, situated at a distance from the transverse plane of the P junction passing through. by the transverse ends of the transverse fold line 4, and preferably at the same height as the orifices 16 located (s) on the second longitudinal fold line 10. The recess 17 is preferably substantially of the same longitudinal dimension as the orifices 15 and 16, and has a transverse dimension substantially equal to half the transverse dimension of the orifices 15 and 16, thus forming substantially a half-orifice. When folding the blank 1 for the manufacture of the packaging device, the recess 17 is superimposed with a portion of the corresponding orifice 16 located on the side of the longitudinal flap 9 and the same height, which contributes to better damping packaging device once manufactured.

Dans une variante de ce deuxième mode de réalisation, au moins un des orifices 15, 16, et/ou au moins un des évidements 17, est relié à au moins une rainure (ou fente traversante) 18 qui s'étend de préférence dans une direction sensiblement transversale (figure 4). La présence de chaque rainure 18 permet de renforcer l'effet d'amortissement en formant des soufflets d'amortissement de plus grandes dimensions transversales dans le dispositif d'emballage une fois fabriqué.In a variant of this second embodiment, at least one of the orifices 15, 16, and / or at least one of the recesses 17, is connected to at least one groove (or through slot) 18 which preferably extends in a substantially transverse direction ( figure 4 ). The presence of each groove 18 reinforces the damping effect by forming damping bellows of larger transverse dimensions in the packaging device once manufactured.

Chaque rainure 18 est avantageusement sensiblement parallèle à la ligne de pliage transversale la plus proche (figures 5 et 6). Chaque orifice 15, 16 peut être relié à une unique rainure située d'un seul côté de la ligne de pliage longitudinale 4, sur une zone longitudinale 2, 3, ou de préférence à deux rainures 18 situées de part et d'autre de l'orifice 15, 16, sur deux zones longitudinales 2, 3 ou sur le rabat longitudinal 9 et sur la zone longitudinale 3 adjacente au rabat 9. Dans la variante illustrée à la figure 6, les rainures 18 s'étendent sensiblement sur toute la dimension transversale des zones longitudinales 2, 3. Chaque rainure 18 située dans le rabat longitudinal 9 peut également s'étendre sur une grande partie de la dimension transversale du rabat 9.Each groove 18 is advantageously substantially parallel to the nearest transverse fold line ( Figures 5 and 6 ). Each orifice 15, 16 may be connected to a single groove located on one side of the longitudinal fold line 4, on a longitudinal zone 2, 3, or preferably two grooves 18 located on either side of the groove. 15, 16, on two longitudinal zones 2, 3 or on the longitudinal flap 9 and on the longitudinal zone 3 adjacent to the flap 9. In the variant illustrated in FIG. figure 6 , the grooves 18 extend substantially over the entire transverse dimension of the longitudinal zones 2, 3. Each groove 18 situated in the longitudinal flap 9 can also extend over a large part of the transverse dimension of the flap 9.

Les rainures 18 peuvent être formées sur une des faces ou sur les deux faces des zones longitudinales 2, 3. Les orifices 15, 16 ont par exemple un diamètre compris entre 0.5 et 5 mm, et de préférence entre 1 et 3 mm.The grooves 18 may be formed on one or both faces of the longitudinal zones 2, 3. The orifices 15, 16 have for example a diameter of between 0.5 and 5 mm, and preferably between 1 and 3 mm.

Le flan 1 décrit ci-dessus est utilisé pour la fabrication d'un dispositif d'emballage d'au moins un balai d'essuie-glace, tel que représenté à la figure 7. La fabrication du dispositif d'emballage peut comprendre les étapes suivantes :

  • une étape de pliage du flan 1 le long de la ligne de pliage longitudinale 4, de manière à faire adhérer une face du rabat 9 sur une portion d'une face de la zone longitudinale 3, de préférence de sorte que les lignes de pliage longitudinales 10, 13 soient sensiblement confondues,
  • une étape de solidarisation du rabat 9 à la bordure 13, par exemple par collage (la colle peut être déjà présente sur le rabat 9 ou rapportée sur celui-ci), le dispositif présente alors un contour transversalement fermé comprenant les faces longitudinales 2', 3' du dispositif d'emballage, et
  • une étape de pliage des zones d'extrémité 21, 22, 31, 32 du flan 1 vers l'intérieur du contour transversalement fermé, de manière à former les faces transversales 21', 31' du dispositif.
The blank 1 described above is used for the manufacture of a packaging device for at least one windscreen wiper blade, as shown in FIG. figure 7 . The manufacture of the packaging device may comprise the following steps:
  • a step of folding the blank 1 along the longitudinal fold line 4, so as to adhere a face of the flap 9 on a portion of a face of the longitudinal zone 3, preferably so that the longitudinal fold lines 10, 13 are substantially merged,
  • a step of securing the flap 9 to the edge 13, for example by gluing (the glue may already be present on the flap 9 or attached thereto), the device then has a transversely closed contour comprising the longitudinal faces 2 ', 3 'of the packaging device, and
  • a folding step of the end zones 21, 22, 31, 32 of the blank 1 towards the inside of the transversely closed contour, so as to form the transverse faces 21 ', 31' of the device.

La figure 8A montre au repos, dans une configuration normale, non déformée, l'extrémité basse d'un dispositif fabriqué à partir d'un flan selon le premier mode de réalisation. Lorsque l'extrémité basse du dispositif est soumise à un choc, la zone située autour de la fente 11' va se déformer, préservant ainsi le dispositif et son contenu. La figure 8B illustre l'extrémité basse du dispositif dans sa position déformée, la fente 11' ayant adopté une forme plus ouverte, par exemple en V.The figure 8A shows at rest, in a normal configuration, not deformed, the bottom end of a device made from a blank according to the first embodiment. When the lower end of the device is subjected to impact, the area around the slot 11 'will deform, thus preserving the device and its contents. The Figure 8B illustrates the bottom end of the device in its deformed position, the slot 11 'having adopted a more open form, for example V.

De la même façon, la figure 9A montre au repos, dans une configuration normale, non déformée, l'extrémité basse d'un dispositif fabriqué à partir d'un flan selon le deuxième mode de réalisation. Lorsque l'extrémité basse du dispositif est soumise à un choc, la zone située autour des orifices 15' va se déformer, par exemple par compression, préservant ainsi le dispositif et son contenu. La figure 9B illustre l'extrémité basse du dispositif dans sa position déformée.In the same way, Figure 9A shows at rest, in a normal configuration, not deformed, the bottom end of a device made from a blank according to the second embodiment. When the lower end of the device is subjected to impact, the area around the orifices 15 'will deform, for example by compression, thus preserving the device and its contents. The Figure 9B illustrates the low end of the device in its deformed position.

Le dispositif d'emballage est adapté à l'emballage de balai(s) d'essuie-glace, et tout particulièrement à l'emballage de balai(s) à lame courbe de type « flat blade ». On utilise préférentiellement pour le flan un matériau rigide, par exemple un matériau plastique choisi parmi le poly(téréphtalate d'éthylène) (PET), le poly(chlorure de vinyle) (PVC) ou encore le polypropylène (PP). Le flan peut également être réalisé en carton. Le flan a par exemple une épaisseur comprise entre 0.1 et 1 mm, et de préférence comprise entre 0.2 mm et 0,6 mm.The packaging device is suitable for wrapping wiper blades (s), and particularly for wrapping (s) flat blade curved blade (s). A rigid material is preferably used for the blank, for example a plastic material chosen from polyethylene terephthalate (PET), polyvinyl chloride (PVC) or even polypropylene (PP). The blank can also be made of cardboard. The blank has for example a thickness of between 0.1 and 1 mm, and preferably between 0.2 mm and 0.6 mm.
