Description

EMBALLAGE EN CARTON ET FLAN POUR CELUI-CI CARDBOARD AND BLANK PACKAGING THEREFOR

La présente invention concerne un procédé de fabrication d'un emballage à partir d'un flan de carton ou de matière similaire. Elle concerne également le flan de carton ou de matière similaire pour la mise en œuvre du procédé et l'emballage obtenu par la mise en volume de ce flan ; elle concerne aussi un procédé de conditionnement de produit(s) au moyen du flan en question. La mise en volume ou la fermeture des emballages réalisés à partir d'un flan unique de carton ou de matière similaire s'effectue bien souvent au moyen de rabats, de volets ou de languettes d'assemblage qui sont aménagées dans le prolongement des portions de matière qui assurent le conditionnement proprement dit. Or, ces éléments de prolongement augmentent la surface de flan nécessaire à la réalisation de l'emballage et ils augmentent de ce fait son coût de revient.The present invention relates to a method of manufacturing a packaging from a blank of cardboard or similar material. It also relates to the blank of cardboard or similar material for the implementation of the process and the packaging obtained by the volume of this blank; it also relates to a process for packaging product (s) by means of the blank in question. The packaging or closing of the packaging produced from a single blank of cardboard or similar material is very often carried out by means of flaps, flaps or assembly tabs which are arranged in the extension of the portions of material which ensures the actual packaging. However, these extension elements increase the blank surface necessary for producing the packaging and they therefore increase its cost price.

Il est possible de supprimer ces éléments de prolongement et de prévoir des structures d'assemblage complémentaires, tel qu'un cerclage au moyen d'un feuillard, ou tel qu'un suremballage au moyen d'un film plastique, mais ces structures complémentaires nécessitent la mise en œuvre de moyens techniques qui sont eux aussi d'un coût de revient assez élevé et qui ne sont pas toujours faciles à mettre en œuvre.It is possible to remove these extension elements and to provide additional assembly structures, such as a strapping by means of a strip, or such as an overpack by means of a plastic film, but these complementary structures require the implementation of technical means which are also of a relatively high cost price and which are not always easy to implement.

La présente invention propose une nouvelle technique de fabrication d'emballage qui permet de remédier à cet inconvénient. Ce procédé permet en particulier de limiter, voire même de supprimer les prolongements d'assemblage du flan de carton de base, sans imposer la présence de structures complémentaires d'assemblage tels les feuillards ou les films plastiques de suremballage connus dans l'état de la technique.The present invention provides a new packaging manufacturing technique which overcomes this drawback. This process makes it possible in particular to limit, or even to eliminate the assembly prolongations of the blank of cardboard base, without imposing the presence of complementary assembly structures such as the strips or the plastic overwrapping films known in the state of the art. technical.

Le procédé de fabrication d'emballage(s) conforme à la présente invention consiste à prélever au moins une pièce de matière dans le flan de base, puis, après mise en volume dudit flan, à utiliser ladite pièce de matière pour assembler les bordures supérieures de deux parois latérales dudit emballage et former ainsi un volet de recouvrement des produits conditionnés. On utilise la pièce de matière prélevée pour assurer le maintien du volume, pour compléter les moyens de maintien en volume et/ou pour fermer l'emballage.The method of manufacturing packaging (s) according to the present invention consists in removing at least one piece of material from the blank base, then, after volume setting of said blank, to use said piece of material to assemble the upper edges of two side walls of said packaging and thus form a cover for covering the packaged products. The piece of material removed is used to maintain the volume, to complete the volume maintenance means and / or to close the packaging.

L'invention concerne également le flan de carton pour la mise en œuvre de ce procédé et l'emballage en carton obtenu par la mise en volume de ce flan au moyen de la technique précitée.The invention also relates to the cardboard blank for the implementation of this process and the cardboard packaging obtained by the volume of this blank using the aforementioned technique.

Selon une forme de réalisation particulière, cet emballage comporte au moins une pièce de matière qui est prélevée dans le flan de carton et qui est utilisée pour assembler les bordures supérieures de deux des parois latérales. L'emballage comprend de préférence un fond à partir duquel s'étendent au moins deux parois latérales en opposition ; il comporte également au moins une pièce de matière assurant l'assemblage desdites parois en opposition, laquelle pièce de matière est découpée au moins partiellement dans le fond et/ou dans l'une au moins desdites parois latérales. De préférence, cette pièce d'assemblage est totalement découpée dans le fond et/ou dans l'une au moins des parois latérales et elle comporte un volet de recouvrement qui est prolongé latéralement par deux pattes d'extrémités qui viennent se solidariser avec lesdites parois latérales. Conformément à un second mode de réalisation, la pièce d'assemblage est partiellement découpée dans le flan de base et elle reste attenante à l'une des parois latérales. Cette pièce d'assemblage comporte un volet de recouvrement qui est prolongé par une patte d'extrémité venant se solidariser avec l'autre paroi latérale. Selon une autre caractéristique de l'invention, l'emballage comporte une pièce d'assemblage dont le volet de recouvrement est prélevé sur toute la longueur du fond et dont la ou les pattes d'extrémités sont prélevées sur l'une ou sur les deux parois latérales, selon le cas.According to a particular embodiment, this packaging comprises at least one piece of material which is taken from the cardboard blank and which is used to assemble the upper edges of two of the side walls. The packaging preferably comprises a bottom from which extend at least two opposing side walls; it also comprises at least one piece of material ensuring the assembly of said opposing walls, which piece of material is cut at least partially in the bottom and / or in at least one of said side walls. Preferably, this assembly part is completely cut out in the bottom and / or in at least one of the side walls and it comprises a covering flap which is extended laterally by two end tabs which come to join with said walls side. According to a second embodiment, the assembly part is partially cut out from the base blank and it remains adjacent to one of the side walls. This assembly part comprises a covering flap which is extended by an end tab coming to join with the other side wall. According to another characteristic of the invention, the packaging comprises an assembly part whose covering flap is taken from the entire length of the bottom and the end tab (s) of which are taken from one or both of the side walls, as the case may be.

Toujours selon l'invention, l'emballage comporte une pièce d'assemblage dont le volet de recouvrement et la ou les pattes d'extrémités sont positionnées en correspondance des découpes de prélèvement dans le fond et dans la ou les parois latérales. Cette particularité permet de former des organes de calage qui stabilisent les empilements.Still according to the invention, the packaging comprises an assembly part, the covering flap and the end tab or tabs of which are positioned in correspondence with the sampling cut-outs in the bottom and in the side wall or walls. This feature makes it possible to form wedging members which stabilize the stacks.

Toujours selon l'invention, l'emballage est constitué d'un fond carré ou rectangulaire dont deux côtés en opposition se prolongent par deux premières parois latérales munies de rabats latéraux et reliées entre elles par la pièce d'assemblage. Les deux autres côtés du fond se prolongent par des volets qui sont destinés à former les deux autres parois latérales, ou des portions de parois latérales, lesquelles sont solidarisées avec les rabats latéraux précités qui prolongent lesdites premières parois latérales.Still according to the invention, the packaging consists of a square or rectangular bottom, two opposing sides of which extend by two first side walls provided with side flaps and connected to each other by the assembly part. The other two sides of the bottom are extended by flaps which are intended to form the other two side walls, or portions of side walls, which are secured to the aforementioned side flaps which extend said first side walls.

L'invention concerne encore un procédé de conditionnement de produit(s) au moyen du flan de carton, lequel procédé consiste, après prélèvement de la pièce de matière, à mettre en volume ledit flan sur les produits que l'on désire conditionner, ou bien à mettre en volume ledit flan puis à introduire les produits dans l'ouverture supérieure de l'emballage ainsi formé, avant d'assembler les bordures supérieures de deux parois latérales au moyen de la pièce de matière prélevée, pour terminer le cloisonnement du ou des produit(s). • The invention also relates to a method of packaging product (s) by means of the cardboard blank, which method consists, after removal of the piece of material, to volume said blank on the products which it is desired to package, or well to volume said blank then to introduce the products into the upper opening of the packaging thus formed, before assembling the upper edges of two side walls by means of the piece of material removed, to complete the partitioning of the or some products). •

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante de deux modes de réalisation particuliers, donnés uniquement à titre d'exemples et représentés sur les dessins annexés dans lesquels :However, the invention will be further illustrated, without being in any way limited, by the following description of two particular embodiments, given solely by way of examples and represented in the appended drawings in which:

- la figure 1 est une vue à plat d'un flan de carton permettant la réalisation d'un emballage conforme à la présente invention ; - la figure 2 est une vue en perspective qui montre l'emballage mis en volume à partir du flan de la figure 1 ; - la figure 3 est une vue à plat d'un flan de carton permettant la réalisation d'un autre emballage conforme à la présente invention ;- Figure 1 is a flat view of a cardboard blank for making a package according to the present invention; - Figure 2 is a perspective view which shows the packaging set in volume from the blank of Figure 1; - Figure 3 is a flat view of a cardboard blank for making another package according to the present invention;

- la figure 4 est une vue en perspective qui montre l'emballage obtenu à partir du flan de la figure 3, en cours d'assemblage. Le flan 1 représenté à plat sur la figure 1 comprend un fond rectangulaire 2 bordé par deux parois d'extrémités 3 et 4 raccordées respectivement par les lignes de pliage 5 et 6. Les deux parois 3 et 4 ont la même hauteur a et la même largeur b.- Figure 4 is a perspective view which shows the packaging obtained from the blank of Figure 3, during assembly. The blank 1 shown flat in FIG. 1 comprises a rectangular bottom 2 bordered by two end walls 3 and 4 connected respectively by the fold lines 5 and 6. The two walls 3 and 4 have the same height a and the same width b.

Les grands côtés du fond 2 comportent des volets de prolongement 8 raccordés par une ligne de pliage 9. Ces volets 8 s'étendent sur toute la longueur du fond 2 et leur hauteur ç est inférieure à la hauteur a des parois d'extrémités 3 et 4.The long sides of the bottom 2 have extension flaps 8 connected by a fold line 9. These flaps 8 extend over the entire length of the bottom 2 and their height ç is less than the height of the end walls 3 and 4.

D'autre part, les parois d'extrémités 3 et 4 comportent des rabats latéraux 10 raccordés par les lignes de pliage 11. Ces rabats 10 s'étendent sur toute la hauteur a des parois 3 et 4 ; leur largeur d correspond à la hauteur ç des prolongements 8.On the other hand, the end walls 3 and 4 have side flaps 10 connected by the fold lines 11. These flaps 10 extend over the entire height has walls 3 and 4; their width d corresponds to the height ç of the extensions 8.

Le fond 2 et les parois d'extrémités 3, 4 sont placés sur l'axe longitudinal 12 du flan 1 ; ce dernier est découpé dans une plaque de carton ondulé dont les cannelures, repérées en 13, sont orientées dans le sens de l'axe longitudinal 12.The bottom 2 and the end walls 3, 4 are placed on the longitudinal axis 12 of the blank 1; the latter is cut from a corrugated cardboard plate, the grooves of which, identified at 13, are oriented in the direction of the longitudinal axis 12.

Dans la partie centrale du flan 1 , on remarque la présence d'une pièce de matière 14 en forme de bande qui est délimitée, latéralement, par une ligne de coupe 15 et par une ligne de prédécoupe 16 parallèles entre elles et, au niveau de ses extrémités, par des lignes de prédécoupe 17, 18 également parallèles entre elles.In the central part of the blank 1, we note the presence of a piece of material 14 in the form of a strip which is delimited, laterally, by a cutting line 15 and by a precut line 16 parallel to each other and, at the level of its ends, by precut lines 17, 18 also parallel to each other.

La ligne de coupe 15 et les lignes de prédécoupe 16, 17, 18 sont adaptées pour permettre le détachement complet de la bande de matière 14 du flan de carton 1.The cutting line 15 and the precut lines 16, 17, 18 are adapted to allow complete detachment of the strip of material 14 from the cardboard blank 1.

Cette bande 14 de largeur constante s'étend sur toute la longueur du fond 2 et sur une partie des parois d'extrémités 3 et 4. Elle est divisée en trois tronçons : une partie centrale 20 prolongée à chacune de ses extrémités par des pattes 21 raccordées par des lignes de pliage 22. Les lignes de pliage 22 sont pratiquement positionnées sur les lignes de pliage 5 et 6 qui raccordent le fond 2 et les parois d'extrémités 3, 4 ; elles sont en fait légèrement décalées extérieurement par rapport auxdites lignes 5 et 6, d'une distance qui correspond à l'épaisseur du carton utilisé. La partie centrale 20 de la pièce de matière 14 est disposée légèrement en biais par rapport à l'axe longitudinal 12 du flan 1 mais cette pièce de matière 14 reste tout de même symétrique par rapport audit axe longitudinal 12. Selon une forme de réalisation voisine, la bande 14 pourra être rectiligne et s'étendre parallèlement à l'axe longitudinal 12, de préférence centrée sur ce dernier.This strip 14 of constant width extends over the entire length of the bottom 2 and over part of the end walls 3 and 4. It is divided into three sections: a central part 20 extended at each of its ends by lugs 21 connected by fold lines 22. The fold lines 22 are practically positioned on fold lines 5 and 6 which connect the bottom 2 and the end walls 3, 4; they are in fact slightly offset externally with respect to said lines 5 and 6, by a distance which corresponds to the thickness of the cardboard used. The central part 20 of the piece of material 14 is disposed slightly at an angle with respect to the longitudinal axis 12 of the blank 1 but this piece of material 14 remains nevertheless symmetrical with respect to said longitudinal axis 12. According to a neighboring embodiment , the strip 14 may be straight and extend parallel to the longitudinal axis 12, preferably centered on the latter.

Tel que représenté figure 2, la mise en volume du flan de carton s'effectue après enlèvement de la bande de matière 14, en dressant verticalement les parois d'extrémités 3 et 4 et en solidarisant les rabats latéraux 10 avec les volets de prolongements 8. Cette solidarisation est réalisée par collage ou agrafage des extrémités inférieures des rabats 10 avec la face externe ou avec la face interne des extrémités des prolongements 8.As shown in Figure 2, the volume of the cardboard blank is made after removal of the strip of material 14, vertically erecting the end walls 3 and 4 and securing the side flaps 10 with the extension flaps 8 This joining is carried out by gluing or stapling the lower ends of the flaps 10 with the external face or with the internal face of the ends of the extensions 8.

La mise en volume de l'emballage peut être réalisée sur les produits que l'on désire conditionner, par exemple un groupement de 5 boîtes ou étuis 24, après avoir positionné ces derniers sur le fond 2 ; une autre possibilité consiste, après avoir mis l'emballage en volume, à introduire le ou les produits par l'ouverture supérieure. Les volets de prolongement 8 et les rabats 10 maintiennent latéralement le ou les produits conditionnés.The packaging of the volume can be carried out on the products which it is desired to condition, for example a group of 5 boxes or cases 24, after having positioned the latter on the bottom 2; another possibility consists, after having put the packaging in volume, to introduce the product (s) through the upper opening. The extension flaps 8 and the flaps 10 laterally hold the packaged product or products.

La bande de matière 14 prélevée dans le flan de carton 1 sert à fermer l'ouverture supérieure de l'emballage. Cette fermeture partielle est obtenue en plaçant la bande 14 sur les produits 24 et en solidarisant ses pattes d'extrémités 21 par collage, agrafage ou autre, avec la face externe des parois d'extrémités 3 et 4. La bande 14, et en particulier sa partie centrale 20, définit une sorte de coiffe ou de couvercle partiel qui permet de réunir les bordures supérieures des parois 3 et 4 et qui permet de terminer le cloisonnement des produits. Les lignes de pliage 22 qui relient la partie centrale 20 et les pattes d'extrémités 21 sont adaptées pour venir se positionner sur les bordures supérieures des parois 3 et 4.The strip of material 14 taken from the cardboard blank 1 serves to close the upper opening of the packaging. This partial closure is obtained by placing the strip 14 on the products 24 and by joining its end tabs 21 by gluing, stapling or the like, with the external face of the end walls 3 and 4. The strip 14, and in particular its central part 20 defines a kind of cap or partial cover which allows the upper edges of the walls 3 and 4 to be joined together and which enables the partitioning of the products to be completed. The fold lines 22 which connect the central part 20 and the end tabs 21 are adapted to be positioned on the upper edges of the walls 3 and 4.

De préférence, la bande 20 et les pattes d'extrémités 21 sont placées en correspondance de la découpe de prélèvement 25 aménagée dans le fond 2 et dans la partie inférieure des parois d'extrémités 3, 4. La pièce de matière 14 s'étend en surépaisseur au-dessus de la bordure supérieure de l'emballage et la découpe 25 définit un léger évidement.Preferably, the strip 20 and the end tabs 21 are placed in correspondence with the sampling cutout 25 arranged in the bottom 2 and in the lower part of the end walls 3, 4. The piece of material 14 extends in excess thickness above the upper edge of the packaging and the cutout 25 defines a slight recess.

Lorsque les emballages sont empilés, la pièce d'assemblage 14 de l'emballage du dessous pénètre dans la découpe 25 de l'emballage situé juste au-dessus et cela permet d'assurer un certain calage qui stabilise les empilements.When the packages are stacked, the assembly part 14 of the package below penetrates into the cutout 25 of the package located just above and this ensures a certain wedging which stabilizes the stacks.

On obtient un emballage parallélépipédique qui assure un conditionnement correct des produits et qui, du fait de la simplicité de son flan de réalisation, a un coût de revient très intéressant. En outre, la bande supérieure 20 peut servir de poignée pour l'emballage ; on peut aussi l'utiliser pour recevoir un marquage quelconque, par exemple publicitaire.A parallelepipedic packaging is obtained which ensures correct packaging of the products and which, because of the simplicity of its blank, has a very attractive cost price. In addition, the upper strip 20 can serve as a handle for packaging; it can also be used to receive any marking, for example advertising.

La figure 3 montre un autre type de flan qui permet l'obtention d'un emballage similaire illustré sur la figure 4. Ce flan de carton 26 comporte un fond rectangulaire 27 qui est bordé par deux parois d'extrémités 28, 29 raccordées par les lignes de pliage 30, 31 , et par deux volets de prolongements 32 raccordés par les lignes de pliageFIG. 3 shows another type of blank which makes it possible to obtain a similar packaging illustrated in FIG. 4. This cardboard blank 26 has a rectangular bottom 27 which is bordered by two end walls 28, 29 connected by the fold lines 30, 31, and by two extension flaps 32 connected by the fold lines

33.33.

Les parois d'extrémités 28 et 29 comportent des rabats latéraux 34 qui sont destinés à être assemblés avec les prolongements 32 pour maintenir l'emballage en volume.The end walls 28 and 29 have lateral flaps 34 which are intended to be assembled with the extensions 32 to maintain the packaging in volume.

Le flan 26 comporte également une pièce d'assemblage en forme de bande 35 qui s'étend sur la longueur du fond 27 et partiellement sur les deux parois d'extrémités 28 et 29. La bande d'assemblage 35 s'étend sur l'axe longitudinal 36 du flan 26. Elle est attenante au flan 26 par une ligne de raccordement 37 située sur la paroi d'extrémité 29. Par ailleurs, elle est délimitée par une ligne de coupe ou de prédécoupe 38, en forme générale de U.The blank 26 also includes an assembly piece in the form of a strip 35 which extends over the length of the bottom 27 and partially on the two end walls 28 and 29. The assembly strip 35 extends over the longitudinal axis 36 of the blank 26. It adjoins the blank 26 by a connection line 37 located on the end wall 29. Furthermore, it is delimited by a cutting or precut line 38, in general U shape.

La ligne de raccordement 37 est parallèle à la ligne de pliage 31 et à la bordure supérieure 39 de la paroi 29. Elle s'étend sensiblement à mi- hauteur de ladite paroi 29, entre la ligne de pliage 31 et la bordure supérieure 39.The connection line 37 is parallel to the fold line 31 and to the upper edge 39 of the wall 29. It extends substantially at mid-height of said wall 29, between the fold line 31 and the upper edge 39.

La bande d'assemblage 35 comporte ainsi un volet central 40 prélevé sur le fond 27, une première patte d'extrémité 41 prélevée sur la paroi 29 et une seconde patte d'extrémité 42 prélevée sur la paroi 28. La mise en volume de l'emballage s'effectue en solidarisant les prolongements 32 avec les rabats latéraux 34, par exemple par collage. Tel qu'on l'a représenté sur la figure 4, la bande d'assemblage 35 est dégagée du fond 27 ; elle est retournée par l'extérieur et elle est positionnée sur la partie supérieure de l'emballage pour venir raccorder les deux parois d'extrémités 28 et 29. La patte 41 reste attenante à la paroi 29 par la ligne de raccordement 37. Le maintien final de la mise en volume, ou la fermeture, est réalisé après conditionnement des produits, en solidarisant la patte d'extrémité 42 avec la paroi 28. Dans ce mode de réalisation, la ligne de pliage 43 qui raccorde le volet central 40 de la bande d'assemblage 35 avec la patte d'extrémité 41 , vient se positionner sur la bordure supérieure 39 de la paroi d'extrémité 29 ; de l'autre côté, la ligne de pliage 44 qui raccorde le volet central 40 et la patte d'extrémité 42 vient se positionner sur la bordure supérieure de la paroi d'extrémité 28. Ces lignes de pliage 43 et 44 sont positionnées en conséquence sur le flan 26.The assembly strip 35 thus comprises a central flap 40 taken from the bottom 27, a first end tab 41 taken from the wall 29 and a second end tab 42 taken from the wall 28. The volume of the 'packaging is done by securing the extensions 32 with the side flaps 34, for example by gluing. As shown in Figure 4, the assembly strip 35 is released from the bottom 27; it is turned over from the outside and it is positioned on the upper part of the packaging to connect the two end walls 28 and 29. The tab 41 remains attached to the wall 29 by the connection line 37. The maintenance final volume setting, or closing, is carried out after packaging the products, by joining the end tab 42 with the wall 28. In this embodiment, the fold line 43 which connects the central flap 40 of the assembly strip 35 with the end tab 41, is positioned on the upper edge 39 of the end wall 29; on the other side, the fold line 44 which connects the central flap 40 and the end tab 42 is positioned on the upper edge of the end wall 28. These fold lines 43 and 44 are positioned accordingly on the blank 26.

Pour faciliter le retournement et le positionnement de la bande d'assemblage partiellement découpée 35, on peut prévoir une ligne de pliage sur la ligne de raccordement 37.To facilitate the turning and positioning of the partially cut assembly strip 35, a fold line can be provided on the connection line 37.

Dans ce mode de réalisation, également, la bande d'assemblage 35 fait légèrement saillie au-dessus des bordures supérieures de l'emballage et elle constitue un élément de calage, en association avec sa découpe 45 aménagée dans le fond, qui permet de stabiliser les empilements. In this embodiment, too, the assembly strip 35 protrudes slightly above the upper edges of the packaging and it constitutes a wedging element, in association with its cutout 45 in the bottom, which stabilizes the stacks.
