Abstract

The panel is made from a core of a corrugated material between two plain layers that are stuck to the core, and has one surface impressed to receive the bottoms of the cans. The impressions (11) have circular edges (12), forming round areas in which the corrugations are completely crushed in the centre and partially round the outside. Each end of the panel has a projecting strip (104) with slits (105) and rectangular U-shaped cuts (106) that allow them to be folded.

Description

La présente invention concerne le conditionnement de récipients, par exemple de boítes ou conteneurs de liquide, notamment des conteneurs de liquide alimentaire connus sous le nom de « cans » ; elle consiste notamment en une plaque de positionnement adaptée pour positionner de manière juxtaposée des récipients du type « cans » afin de faciliter leur enveloppement dans une enveloppe ou housse en matière synthétique ou même éventuellement en cartonnage pour former un paquet, et de sécuriser leur transport ainsi conditionnés ; elle consiste également en un paquet de récipients connu sous le nom de « pack » comportant une telle plaque, et un procédé de conditionnement de récipients mis en oeuvre au moyen d'une telle plaque de positionnement, afin de former un tel paquet.The present invention relates to the packaging of containers, for example boxes or containers of liquid, in particular containers liquid food known as "cans"; it consists in particular in a positioning plate adapted to position juxtaposed containers of the type "cans" to facilitate their wrap in an envelope or cover made of synthetic material or even possibly in cardboard to form a package, and secure their transport thus conditioned; it also consists of a packet of containers known as a "pack" containing such a plate, and a a method of packaging containers implemented by means of a such a positioning plate, to form such a package.

Actuellement, le conditionnement en quantité, sous feuille en matière synthétique, de récipients tels que des cans ou des bouteilles, nécessite d'importantes précautions afin d'empêcher que les récipients, même en contact mutuel, se déplacent les uns par rapport aux autres préalablement à et lors de leur enveloppement en commun par la même feuille en matière synthétique. Pour éviter le glissement des récipients les uns contre les autres une fois enveloppés, il est nécessaire que la feuille d'enveloppement soit en matériau très étirable à froid, ou thermorétractable.Currently, quantity packaging, under sheet in synthetic material, containers such as cans or bottles, important precautions to prevent the containers, even in mutual contact, move relative to each other prior to and during their joint wrapping by the same sheet of synthetic material. To avoid slipping containers against each other once wrapped, it is necessary that the sheet wrapping either in very cold-stretchable material, or heat-shrinkable.

Le conditionnement en quantité sous cartonnage permet d'éviter le glissement des récipients les uns contre les autres une fois enveloppés, à condition de créer dans la feuille de carton initiale, des ouvertures disposées convenablement pour coïncider avec des régions saillantes des récipients de telle manière qu'une fois le carton replié autour du groupe de récipients, ces régions saillantes fassent proéminence à travers les ouvertures vers l'extérieur du cartonnage et qu'ainsi les récipients soient empêchés de se déplacer dans le cartonnage et de déformer celui-ci ; il est également nécessaire de créer dans la feuille de carton initiale un système de fentes et de languettes adapté pour « verrouiller » le cartonnage après enveloppement des récipients. En revanche, le déplacement mutuel des récipients tant que leurs régions saillantes n'ont pas pénétré dans les ouvertures correspondantes reste difficile à éviter. Packaging in quantities under cardboard makes it possible to avoid sliding of the containers against each other once wrapped, to condition of creating in the initial cardboard sheet openings arranged suitably to coincide with salient regions of the containers in such a way that once the carton is folded around the group of containers, these protruding areas make prominence through the openings towards the outside of the cartonnage and thus the receptacles are prevented from move in the cartonnage and deform it; he is also necessary to create in the initial cardboard sheet a system of slots and of tabs adapted to "lock" the carton after wrapping of the containers. On the other hand, the mutual displacement of containers until their projecting areas have penetrated into the corresponding openings remains difficult to avoid.

On connaít également, par exemple de US 4 474 293 A, des paquets de récipients comprenant un cartonnage de base comportant une âme en carton ondulé et une housse en matière synthétique enveloppant entièrement le cartonnage et les récipients, dont une face du cartonnage présente des empreintes constituées chacune par une ligne en creux s'étendant circonférentiellement le long de laquelle les ondulations de l'âme ondulée sont écrasées, empreintes dans lesquelles les nervures annulaires respectives des fonds des conteneurs sont reçues lors de la dépose des conteneurs sur le cartonnage. Cependant, de telles lignes écrasées ne positionnent pas très efficacement les conteneurs.Also known, for example from US 4,474,293 A, packets of containers comprising a basic carton having a corrugated core and a cover synthetic material completely enclosing the carton and the receptacles, of which one side of the carton has imprints each made up by a hollow line extending circumferentially along which the undulations of the wavy soul are crushed, imprints in which the respective annular ribs of the bottoms of the containers are received when removing containers from the carton. However, such crushed lines do not position containers very efficiently.

L'invention a pour but de remédier à ces inconvénients et plus précisément de permettre d'envelopper des récipients en quantité en évitant leur déplacement préalablement à leur enveloppement, lors de celui-ci, et également ultérieurement, sans nécessiter l'emploi d'une machine extrêmement puissante.The object of the invention is to remedy these drawbacks and more precisely to allow containers to be wrapped in quantity avoiding their displacement prior to their envelopment, during this one, and also later, without the need for a machine extremely powerful.

Grâce à cette configuration, les récipients posés sur la plaque de telle manière que leur fond soit en relation d'engagement chacun avec une empreinte de celle-ci, sont empêchés de glisser sur la plaque et ainsi de se déplacer les uns par rapport aux autres, à moins d'exercer sur eux une poussée latérale d'intensité notable.With this configuration, the containers placed on the plate of in such a way that their bottom is in relation of engagement each with a impression of it, are prevented from slipping on the plate and thus from to move relative to each other unless they exercise a lateral thrust of notable intensity.

La plaque de positionnement représentée sur les figures est destinée à entrer dans la constitution d'un paquet de récipients connu sous le nom de « pack », notamment de récipients sous la forme de conteneurs métalliques de forme générale cylindrique connus sous le nom de « cans », ce paquet comprenant, outre les récipients et cette plaque en tant que support de base sur lequel repose le fond de ceux-ci, une housse en matière synthétique par exemple thermorétractable entourant au moins partiellement l'ensemble formé par la plaque et les récipients.The positioning plate shown in the figures is intended to enter into the constitution of a package of containers known as the name 'pack', in particular containers in the form of containers generally cylindrical shaped metal known as "cans", this package including, besides the containers and this plate as basic support on which the bottom of these, a cover made of synthetic, for example heat-shrinkable, at least partially surrounding the assembly formed by the plate and the containers.

Cette plaque présente une structure multicouches, et plus précisément comporte une âme constituée au moins d'une feuille 1A en matériau ondulé, et des feuilles 1B,1C de revêtement extérieur constituées chacune en matériau sans ondulations et qui sont collées respectivement de part et d'autre de l'âme; l'âme constituée ici d'une unique feuille 1A ondulée et les deux feuilles de revêtement 1B, 1C sont par exemple en carton.This plate has a multilayer structure, and more precisely comprises a core consisting of at least one sheet 1A in corrugated material, and outer cover sheets 1B, 1C formed each made of material without corrugations and which are glued respectively from on both sides of the soul; the core constituted here of a single corrugated sheet 1A and the two covering sheets 1B, 1C are for example made of cardboard.

La plaque comporte une face 10 présentant en creux des empreintes 11 de positionnement des récipients destinées à recevoir en relation d'engagement le fond de ceux-ci, afin d'empêcher les récipients de glisser sur la plaque et ainsi de se déplacer les uns par rapport aux autres à moins d'exercer sur eux une poussée latérale d'intensité notable, que ce soit avant leur enveloppement, au moment de celui-ci, et une fois qu'ils sont enveloppés.The plate comprises a face 10 having hollow imprints 11 for positioning the receptacles intended to receive in commitment relation the bottom of these, in order to prevent the containers from slide on the plate and so to move relative to each other to less to exert on them a lateral thrust of notable intensity, whether before their wrap, at the moment of it, and once they are wrapped.

La plaque comporte un nombre d'empreintes en creux 11 égal au nombre de récipients destinés à entrer dans la constitution du paquet, par exemple, comme sur la figure 1, douze empreintes réparties en trois lignes droites longitudinales de quatre empreintes également alignées transversalement pour constituer quatre lignes droites transversales de trois empreintes.The plate has a number of indentations 11 equal to number of receptacles intended to enter into the constitution of the package, by example, as in Figure 1, twelve prints divided into three lines longitudinal lines of four imprints also aligned transversely to form four transverse straight lines of three fingerprints.

Les empreintes s'étendent chacune sur une surface délimitée par au moins une ligne de contour 12 le long de laquelle la feuille de revêtement 1C de la face 10 est découpée de part en part, surface sous laquelle les ondulations de la feuille en matériau ondulé 1A sont au moins partiellement écrasées de telle manière que l'empreinte présente une profondeur d'au moins quelques dixièmes de millimètre. En variante, la ligne de contour 12 peut être non pas une ligne découpée mais une ligne rainée, le long de laquelle les ondulations sont écrasées. Les ondulations situées sous la surface délimitée par la ou les lignes de contour peuvent être écrasées en totalité, ou encore peuvent être seulement rainées dans une direction sécante par rapport à la direction des ondulations. Dans la forme de réalisation des figures 1 et 2, la surface sous laquelle les ondulations sont au moins partiellement écrasées est limitée par un seul contour, extérieur, mais il est également possible de prévoir une telle surface délimitée par deux lignes de contour, la deuxième ligne de contour s'étendant intérieurement à la première, et pouvant être également une ligne le long de laquelle la feuille est découpée de part en part, ou une ligne rainée.The footprints each extend on a surface delimited by minus one contour line 12 along which the coating sheet 1C of the face 10 is cut from one side to the other, the surface under which the corrugations of the sheet of corrugated material 1A are at least partially crushed in such a way that the impression has a depth of at least minus a few tenths of a millimeter. In a variant, the contour line 12 can not be a cut line but a slotted line, along which ripples are crushed. The undulations located under the surface bounded by the contour line (s) can be overwritten whole, or can only be slotted in one direction secant relative to the direction of the undulations. In the form of embodiment of FIGS. 1 and 2, the surface under which the corrugations are at least partially crushed is limited by a single outline, exterior, but it is also possible to provide such a surface delimited by two contour lines, the second contour line extending internally to the first, and can also be a line along which sheet is cut right through, or a slotted line.

Le fond des conteneurs ici approximativement cylindriques devant être positionnés par la plaque comportant une nervure circonférentielle de diamètre inférieur au diamètre extérieur des conteneurs, les empreintes sont de forme sensiblement circulaire, et leur ligne de contour 12 est en totalité ou sur la plus grande partie de sa longueur un arc de circonférence dont le diamètre est légèrement supérieur à celui de la nervure et inférieur à celui du pourtour approximativement cylindrique des conteneurs. Dans le cas où la surface sous laquelle les ondulations sont au moins partiellement écrasées est en outre limitée par une ligne de contour intérieure, cette dernière peut être une circonférence approximativement concentrique à la ligne de contour extérieure 12, et la surface sous laquelle les ondulations sont au moins partiellement écrasées s'étend alors approximativement en forme de couronne annulaire. Dans une application particulière à des conteneurs de sodas ou d'eau minérale classiques, la ligne de contour 12 présente approximativement un diamètre de 53 mm ; dans cette application, il est possible de prévoir une autre ligne de contour s'étendant intérieurement à la ligne de contour 12, à une dizaine de millimètres de celle-ci. L'écartement entre les empreintes est ici identique dans les directions longitudinale et transversale de la plaque, et choisi de telle manière que les pourtours ici approximativement cylindriques des conteneurs positionnés par les empreintes soient en contact dans ces deux directions.The bottom of the containers here approximately cylindrical in front positioned by the plate having a circumferential rib of diameter smaller than the outside diameter of the containers, the impressions are of substantially circular shape, and their contour line 12 is in full or over most of its length an arc of circumference whose diameter is slightly greater than that of the rib and smaller than that around the cylindrical periphery of the containers. In the case where the surface under which the undulations are at least partially crushed is further limited by an inner contour line, this last can be an approximately concentric circumference at the outer contour line 12, and the surface under which the undulations are at least partially crushed then extends approximately annular ring shape. In a particular application to classic soda or mineral water containers, contour line 12 has a diameter of approximately 53 mm; in this application, it is possible to provide another contour line extending internally at the contour line 12, about ten millimeters from it. The distance between the impressions is here identical in the longitudinal and transverse directions of the plate, and chosen from such way that the perimeters here approximately cylindrical of containers positioned by the footprints are in contact in these two directions.

La plaque, de forme générale approximativement rectangulaire, présente deux bords longitudinaux constitués chacun en alternance d'un segment rectiligne et d'un segment arqué, comme on le verra dans la suite, s'étendant dans la même direction que les lignes longitudinales d'empreintes, et deux bords transversaux rectilignes s'étendant dans la même direction que les lignes transversales d'empreintes.The plate, of approximately rectangular general shape, has two longitudinal edges, each consisting alternately of a rectilinear segment and an arched segment, as will be seen later, extending in the same direction as the longitudinal lines of impressions, and two rectilinear transverse edges extending into the same direction as the transverse lines of footprints.

Plus précisément, les empreintes des deux lignes longitudinales d'empreintes les plus proches respectivement des deux bords longitudinaux de la plaque ont une partie de leur ligne de contour qui est en arc de circonférence 121, et également une partie en segment de droite 122 qui constitue en outre une partie de la ligne de contour de la plaque.More precisely, the imprints of the two longitudinal lines of the nearest impressions respectively of the two longitudinal edges of the plate have a part of their contour line which is in arc of circumference 121, and also a segment in right segment 122 which further constitutes a part of the contour line of the plate.

A cette fin, la partie en segment de droite 122 peut être sécante à l'arc de circonférence 121 dudit contour; en alternative, elle peut être approximativement tangente à l'arc de circonférence ou ne pas le couper, mais lui être raccordée par exemple par deux tangentes 123; en outre, le contour des empreintes d'extrémités de chacune des deux lignes longitudinales d'empreintes qui sont les plus proches respectivement des deux bords longitudinaux de la plaque a une partie 124 en arc de circonférence qui constitue également une partie de la ligne de contour de la plaque, reliée à la partie en segment de droite 122 du contour de la même empreinte.For this purpose, the right segment segment 122 may be secant to the circumference arc 121 of said contour; alternatively, it can be approximately tangent to the circumference arc or not to cut it, but be connected to it for example by two tangents 123; in addition, the outline of the end imprints of each of the two lines fingerprints that are closest to each other respectively two longitudinal edges of the plate has a portion 124 in an arc of circumference which is also a part of the contour line of the plate, connected to the straight segment portion 122 of the contour of the same footprint.

Il faut noter que les segments rectilignes des bords longitudinaux de la plaque ne se limitent pas aux parties en segment de droite du contour de chaque empreinte, chacune de ces parties étant prolongée extérieurement à l'empreinte, en direction de la partie en segment de droite du contour de l'empreinte voisine, sans l'atteindre, par un segment de droite additionnel 101.It should be noted that the rectilinear segments of the longitudinal edges of the plate are not limited to the straight segment parts of the contour of each print, each of these parts being extended externally to the imprint, in the direction of the segment in the right segment of the contour of the neighboring footprint, without reaching it, by an additional line segment 101.

Les segments rectilignes de chaque bord longitudinal de la plaque sont raccordés l'un à l'autre par une échancrure 102 de la plaque, présentant un fond arqué relié par deux côtés tangents respectivement aux deux segments rectilignes du bord voisins; chacun de ces deux côtés tangents au fond arqué de l'échancrure 102 est sécant à la projection sur la plaque, du pourtour des conteneurs voisins de l'échancrure.The rectilinear segments of each longitudinal edge of the plate are connected to each other by a notch 102 of the plate, having an arched bottom connected by two sides tangent respectively to two rectilinear segments of the neighboring edge; each of these two sides tangents to the arcuate bottom of the notch 102 is secant to the projection on the plate, around the edge of the containers next to the notch.

Grâce à cette géométrie, le pourtour des conteneurs positionnés par les empreintes en creux déborde des bords longitudinaux de la plaque, d'une partie de contour en arc de circonférence 124 à l'autre incluses, sauf dans le fond arqué des échancrures 102 ; il en résulte que la housse en matière synthétique du paquet n'a pas à épouser les formes du chant des bords longitudinaux de la plaque et en particulier les angles vifs de ce chant, et on peut noter que la matière synthétique, généralement thermorétractable, constituant la housse, ne se rétracte pas entre les conteneurs suffisamment pour venir en contact avec le chant du fond, au demeurant arqué, des échancrures ; ainsi, les risques de déchirure de la housse sont minimisés.Thanks to this geometry, the periphery of the containers positioned by the indentations protrude from the longitudinal edges of the plate, of a circumferential contour portion of circumference 124 to the other inclusive, except in the arched bottom of the indentations 102; it follows that the cover synthetic material of the package does not have to marry the shapes of the singing of longitudinal edges of the plate and in particular the sharp angles of this song, and it can be noted that the synthetic material, generally heat shrink, constituting the cover, does not retract between containers sufficiently to come into contact with the bottom remaining arched, indentations; thus, the risks of tearing the cover are minimized.

Les régions d'extrémités des bords longitudinaux de la plaque sont des segments rectilignes 103 se raccordant aux parties en arc de circonférence 124 du contour des empreintes, situés dans le prolongement du diamètre des empreintes qui est parallèle au segment de droite 122 de celles-ci.The end regions of the longitudinal edges of the plate are rectilinear segments 103 connecting to the arcuate portions of circumference 124 of the outline of the imprints, located in the extension of the diameter of the footprints which is parallel to the line segment 122 of them.

Parallèlement à chaque bord transversal de la plaque, une ligne de moindre résistance s'étend entre les segments rectilignes 103 des régions d'extrémités des bords longitudinaux ; les deux lignes de moindre résistance définissent ainsi avec le bord libre transversal correspondant de la plaque, deux bandes d'extrémités 104 faisant partie intégrante de la plaque, s'étendant parallèlement l'une à l'autre, pliables autour de la ligne de moindre résistance.Parallel to each transversal edge of the plate, a line of least resistance extends between the rectilinear segments 103 of the regions ends of the longitudinal edges; the two lines of least resistance so define with the corresponding transverse free edge of the plate, two end strips 104 forming an integral part of the plate, extending parallel to each other, foldable around the line of less resistance.

La ligne de moindre résistance comporte des fentes 105 alignées traversant la plaque de part en part ; entre les fentes 105, des découpes en U 106 délimitant des languettes 107 sont formées par des fentes traversant également la plaque de part en part.The line of weakness has slots 105 aligned crossing the plate from side to side; between the slots 105, cut-outs U 106 delimiting tabs 107 are formed by through slots also the plate from side to side.

Les bandes d'extrémités 104 sont ainsi adaptées pour être pliées à 90° du côté de la face 10 de la plaque qui comporte les empreintes 11, pour constituer des cloisons d'extrémités transversales du paquet ; les extrémités libres des languettes 107 sont alors en saillie du côté opposé de la plaque et permettent un positionnement correct du paquet sur un autre paquet identique.The end strips 104 are thus adapted to be folded to 90 ° on the side of the face 10 of the plate which comprises the fingerprints 11, for constituting transverse end walls of the package; the extremities free of the tabs 107 are then projecting from the opposite side of the plate and allow correct positioning of the package on another package identical.

Une ou plusieurs empreintes, par exemple, comme sur les figures, deux empreintes disposées symétriquement par rapport au centre de la plaque, sont trouées de part en part par une lumière 13 permettant de lire le code-barres imprimé sous le conteneur positionné dans l'empreinte. Cette lumière peut par exemple présenter la forme d'une ellipse dont le grand axe s'étend dans la même direction que les bords transversaux de la plaque (figure 1) ou que les bords longitudinaux de celle-ci.One or more imprints, for example, as in the figures, two imprints arranged symmetrically with respect to the center of the plate, are pierced through by a light 13 to read the printed barcode under the container positioned in the impression. This light may for example have the shape of an ellipse whose major axis extends in the same direction as the transverse edges of the plate (Figure 1) or that the longitudinal edges thereof.

Ainsi, pour former le paquet de récipients, on forme tout d'abord, en creux dans une face 10 de la plaque, des empreintes 11 de positionnement des récipients que l'on constitue chacune en découpant la feuille de revêtement 1 C de cette face 10 de part en part le long d'au moins une ligne de découpe ou en rainant la feuille pour constituer au moins une ligne rainée afin de délimiter la surface de l'empreinte et en écrasant au moins partiellement les ondulations de la feuille 1A en matériau ondulé sur la surface délimitée par ladite au moins une ligne de manière que celle-ci constitue un contour d'empreinte délimitant une surface sous laquelle les ondulations sont au moins partiellement écrasées. Thus, to form the package of containers, one forms first, in hollow in a face 10 of the plate, positioning fingerprints 11 containers that each constitutes by cutting the sheet of coating 1 C of this face 10 from side to side along at least one line cutting or grooving the sheet to form at least one score line in order to delimit the surface of the impression and at least partially the corrugations of the sheet 1A corrugated material on the surface delimited by said at least one line so that it constitutes an imprint contour delimiting a surface under which the ripples are at least partially crushed.

Puis, on dispose des récipients présentant chacun un fond sur la surface de l'empreinte de manière que ce fond soit bordé extérieurement par la ligne de découpe ou rainée.Then, we have containers each having a bottom on the surface of the impression so that the bottom is bordered externally by the cutting line or slotted.

Enfin, on enveloppe au moins partiellement l'ensemble formé par la plaque et les récipients, au moyen d'une housse en matière synthétique, de préférence une matière thermorétractable.Finally, at least partially the assembly formed by the plate and receptacles, by means of a cover of synthetic material, preferably a heat-shrinkable material.

Bien entendu, l'invention n'est pas limitée aux formes et au modes de réalisation ci-dessus décrits et représentés, et on pourra en prévoir d'autres sans sortir de son cadre.Of course, the invention is not limited to forms and modes described above and shown, and may be provided others without leaving the frame.

Par exemple, on pourra prévoir une forme de réalisation simplifiée dans laquelle la partie de la ligne de contour 12 des empreintes qui constitue en outre une partie de la ligne de contour de la plaque n'est par un segment de droite mais un arc de circonférence, et les échancrures sont également en arc de circonférence, de telle manière que chacun des deux bords longitudinaux de la plaque soit constitué en alternance de segments arqués en sens inverses et se raccordant continûment, par exemple des arcs de circonférence tangents. Une telle forme de réalisation peut être dénuée de bandes d'extrémités, les bords transversaux de la plaque étant alors constitués de la même manière que les bords longitudinaux, en alternance de segments arqués en sens inverses bordant respectivement les empreintes et les échancrures.For example, a simplified embodiment may be provided in which the portion of the contour line 12 of the fingerprints which constitutes furthermore a part of the contour line of the plate is by a segment right but an arc of circumference, and the notches are also in circumference arc, so that each of the two edges of the plate consists alternately of arcuate segments in opposite directions and connecting continuously, for example arcs of circumference tangents. Such an embodiment may be devoid of end strips, the transverse edges of the plate being then formed in the same way as the longitudinal edges, alternately of arcuate segments in opposite directions respectively bordering the footprints and indentations.
