Description

ENSEMBLE DE DECOUPES EN CARTON, BOITE ET PROCEDE DE FABRICATION DE BOITE AVEC DE TELLES DECOUPESCARDBOARD CUT ASSEMBLY, BOX AND METHOD OF MANUFACTURING BOX WITH SUCH DECOUPES
La présente invention concerne un ensemble de découpes pour boîte en carton ou carton ondulé comprenant une coiffe arrachable.The present invention relates to a set of blanks for cardboard box or corrugated cardboard comprising a tear-off cap.
Elle concerne également une boîte obtenue avec un tel ensemble et un procédé de fabrication d'une telle boîte. Elle trouve une application particulièrement importante, bien que non exclusive, dans le domaine des emballages pour produits rigides (bocaux, boîtes... ) ou semi rigides (sacs... ) , permettant de présenter facilement les produits de façon immédiate, propre et attractive, notamment sur les étagères des rayons de magasins à grande surface.It also relates to a box obtained with such a set and a method of manufacturing such a box. It finds a particularly important, although not exclusive, application in the field of packaging for rigid products (jars, boxes ...) or semi-rigid (bags ...), making it easy to present products in an immediate, clean and attractive, especially on the shelves of department store shelves.
On connaît déjà (EP 0 637 548) des caisses d' emballage permettant une déconnexion rapide de la partie supérieure de la caisse par rapport à la partie inférieure formant barquette, autorisant une présentation rapide du contenu de l'emballage dans ladite barquette.Already known (EP 0 637 548) packing cases for quick disconnection of the upper part of the box with respect to the lower portion forming tray, allowing rapid presentation of the contents of the package in said tray.
Une telle caisse, obtenue à partir de deux flans différents collés l'un à l'autre présente cependant l'inconvénient de ne pas permettre d'enlever facilement, rapidement et totalement la coiffe de l'emballage, pour présenter sur une étagère les produits à la verticale sans risquer de les faire glisser. On connaît également (US-A-3, 533, 549) une boîte formée par un flan avec ouverture sur le dessus obtenue par arrachage manuel du couvercle, et poignée renforcée. Ici encore une telle boîte rigide ne permet pas d' enlever facilement le couvercle pour rendre les produits accessibles.Such a box, obtained from two different blanks glued to each other, however, has the disadvantage of not allowing to remove easily, quickly and completely the cap of the package, to present on a shelf products vertically without the risk of dragging them. It is also known (US-A-3, 533, 549) a box formed by a blank with an opening on the top obtained by manual tearing of the lid, and reinforced handle. Here again such a rigid box does not It is not easy to remove the cover to make the products accessible.
La présente invention vise à fournir un ensemble de découpes, une boite et un procédé de fabrication d' une boîte répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'elle autorise l'enlèvement rapide et efficace de la coiffe de l'emballage d'un coup, par simple mouvement d'arrachage manuel. Une présentation impeccable des produits dans une embase en forme de barquette est ainsi obtenue directement sur les étagères dans les magasins, l'emballage avec coiffe y ayant été préalablement placé.The present invention aims to provide a set of blanks, a box and a method of manufacturing a box better than those previously known to the requirements of the practice, in particular in that it allows the quick and efficient removal of the cap Packing at once, by simple manual pulling. An impeccable presentation of the products in a tray-shaped base is thus obtained directly on the shelves in the stores, the packaging with cap having been previously placed.
De plus, l'invention permet une fabrication en automatique à forte cadence (supérieure à vingt boîtes/mn) , que cela soit en boîte montée et prête à être remplie, ou en boîte pliée/collée, les boîtes obtenues présentant une grande solidité et étant par ailleurs aisément gerbables sur palettes. Elle permet également de garantir mieux que précédemment une mise en place parfaitement contrôlée, facile et fiable à 100%, tout en autorisant une résistance optimisée de la zone à déchirer afin de prévenir tout risque accidentel de déchirement des points d'attaches, par exemple à cause d'un choc sur la zone fragilisée ou d'un mouvement violent des produits à l'intérieur de l'emballage, les produits pouvant, dans un mode de réalisation avantageux, jouer eux-mêmes un rôle de soutènement autorisant une excellente résistance à la compression de ce fait.In addition, the invention allows automatic manufacture at a high rate (greater than twenty cans / min), whether in box mounted and ready to be filled, or in box folded / glued, the resulting boxes having great strength and being otherwise easily stackable on pallets. It also makes it possible to guarantee better than previously a perfectly controlled, easy and reliable 100% installation, while allowing optimized resistance of the area to be torn in order to prevent any accidental risk of tearing of the points of attachment, for example to because of a shock on the weakened zone or a violent movement of the products inside the packaging, the products being able, in an advantageous embodiment, to play themselves a role of support allowing an excellent resistance to compression of this fact.
Dans ce but, la présente invention propose notamment un ensemble de découpes pour la constitution d'une boîte d'emballage, comprenant deux découpes en matériau en feuille de carton ondulé, à savoir une première découpe comportant une première suite d'au moins quatre volets principaux terminée par une languette de fixation, reliés entre eux par des premières lignes de pliage parallèles entre elles et munie d'un coté d'une première suite de rabats reliés à ladite première suite de volets par des deuxièmes lignes de pliage perpendiculaires aux dites premières lignes de pliage, ladite première suite de volets étant propre à former les parois de l'embase de la boîte et une deuxième découpe comportant une deuxième suite de trois panneaux reliés entre eux par des troisièmes lignes de pliage parallèles entre elles, et muni de l'autre coté d'une deuxième suite de rabats reliés à ladite deuxième suite de panneaux par des quatrièmes lignes de pliage, ladite deuxième découpe étant propre à former la coiffe de ladite boîte, caractérisé en ce que la première suite de volets comporte un premier volet rectangulaire destiné à former la paroi de fond de l'embase, muni de l'autre coté de la première suite de rabats, d'un rabat arrachable relié audit volet par une ligne de jonction perforée, deux volets trapézoïdaux non adjacents destinés à former les parois latérales de l'embase comportant un bord intérieur dirigé au moins en partie en biais vers un volet central de hauteur réduite destiné à former la paroi de face avant de l'embase, et ledit volet central de hauteur réduite, en ce que la deuxième suite de trois panneaux comporte un panneau central rectangulaire et deux panneaux latéraux trapézoïdaux comportant un bord extérieur dirigé au moins en partie en biais dans la direction de la deuxième suite de rabats, selon des directions parallèles aux bords intérieurs en vis à vis des premiers volets trapézoïdaux lorsque les troisièmes lignes de pliage de la deuxième découpe sont alignées ou sensiblement alignées par rapport aux premières lignes de pliage de la première découpe, et en ce que les deux découpes sont agencées pour permettre un recouvrement suffisant pour autoriser un collage de l'une sur l'autre au niveau des bords intérieurs et extérieurs en vis à vis des volets et panneaux trapézoïdaux lorsque la ligne de pliage perforée et les quatrièmes lignes de pliage sont alignées ou sensiblement alignées.For this purpose, the present invention proposes in particular a set of blanks for the constitution of a packaging box, comprising two cuts made of corrugated sheet material, namely a first cut comprising a first sequence of at least four main shutters terminated by a fastening tab, interconnected by first lines of folding parallel to each other and provided on one side with a first series of flaps connected to said first sequence of flaps by second fold lines perpendicular to said first fold lines, said first sequence of flaps being adapted to form the walls the base of the box and a second cutout comprising a second series of three panels interconnected by third fold lines parallel to each other, and provided on the other side with a second series of flaps connected to said second suite of panels by fourth fold lines, said second cutout being adapted to form the cap of said box, characterized in that e that the first sequence of flaps comprises a first rectangular flap for forming the bottom wall of the base, provided on the other side of the first flap suite, a tear-off flap connected to said flap by a junction line; perforated, two non-adjacent trapezoidal flaps for forming the side walls of the base including an inner edge directed at least partly obliquely to a central flap of reduced height for forming the front face wall of the base, and said central panel of reduced height, in that the second series of three panels comprises a rectangular central panel and two trapezoidal lateral panels comprising an outer edge directed at least partly at an angle in the direction of the second series of flaps, in directions parallel to the inner edges facing the first trapezoidal flaps when the third fold lines of the second blank are aligned or substantially aligned with respect to the first fold lines of the first blank, and in that the two blanks are arranged to allow sufficient overlap to allow a bonding of one over the other at the inner and outer edges facing trapezoidal flaps and panels when the perforated fold line and the fourth fold lines are aligned or substantially aligned.
Par ligne de jonction perforée, on entend une ligne de jonction constituée par quelques points d' attache ou parties d' attache entre le rabat et le volet adjacent, ce qui rend les deux éléments facilement désolidarisables l'un de l'autre, par déchirement de la ligne de jonction en combinant une traction perpendiculaire à la ligne et un détachement progressif des points d'attache l'un après l'autre.Per perforated junction line is meant a joining line consisting of a few attachment points or attachment parts between the flap and the adjacent flap, which makes the two elements easily separable from one another by tearing. the junction line by combining a pull perpendicular to the line and a gradual detachment of the attachment points one after the other.
La ligne de jonction prédécoupée est ainsi agencée pour présenter une bonne résistance dans le sens de la ligne, et/ou tant qu'une amorce de déchirement n'a pas été entamée.The pre-cut junction line is thus arranged to have a good resistance in the direction of the line, and / or as a tear initiation has not been started.
Avantageusement un point dur permet d' éviter un début de déchirement de part et d' autre de la ligne et/ou au milieu.Advantageously, a hard point makes it possible to avoid a beginning of tearing on either side of the line and / or in the middle.
Ainsi, la portion prédécoupée et/ou la ligne prédécoupée sont agencées pour présenter une bonne résistance dans le sens vertical tant que les efforts s'exercent essentiellement dans le plan des parois. Cette résistance est notamment suffisante pour permettre le transport ' des produits même si l'emballage est saisi par la partie supérieure.Thus, the pre-cut portion and / or the precut line are arranged to have a good resistance in the vertical direction as the efforts are exerted essentially in the plane of the walls. This resistance is particularly sufficient for allow the carriage 'products even if the package is seized by the upper part.
Classiquement, la ligne prédécoupée est obtenue en perforant le carton en pointillé avec des lames de découpes appelées " filets perforants " . Les pointillés sont donc définis par une alternance régulière de traits perforés dits " coupeurs " et de traits non perforés dits ΛX points d' attache " .Conventionally, the pre-cut line is obtained by perforating the dotted cardboard with cutting blades called "perforating nets". The dotted lines are therefore defined by a regular alternation of perforated lines called "cutters" and unperforated lines called " X points of attachment".
Dans le cas présent, le trajet suivi par les pointillés devant aussi servir de ligne de pliage, les filets ont également une fonction dite de " rainage ", c'est-à-dire qu'entre les perforations, les points d' attache sont écrasés par des filets plus profonds pour faciliter le pliage ultérieur autour de la ligne concernée.In this case, the path followed by the dotted line must also serve as a fold line, the nets also have a function called "creasing", that is to say between the perforations, the attachment points are crushed by deeper threads to facilitate subsequent folding around the line concerned.
Par sensiblement alignées, on entend alignées (par exemple du fait du machage du rainant de la ligne de pliage) ou dans un mode de réalisation, légèrement décalées par rapport à la ligne de pliage en vis-à- vis d' une valeur correspondant au minimum1 à la valeur cumulée des épaisseurs des papiers constituant les flans, mais néanmoins très faible, c'est à dire d'une valeur inférieure à de l'ordre de 1 ou 2 mm, ou comme précisé ci-après par exemple de 0,5 à 0,7 mm entre rainants.By substantially aligned is meant aligned (for example due to the mashing of the groove of the fold line) or in one embodiment, slightly offset from the fold line vis-à-vis a value corresponding to the minimum 1 to the cumulative value of the thicknesses of the papers constituting the blanks, but nevertheless very small, ie of a value less than of the order of 1 or 2 mm, or as specified hereinafter for example of 0 , 5 to 0.7 mm between grooves.
Les lignes de pliage selon les modes de réalisation de l'invention plus particulièrement décrits sont quant à elles des lignes simples, c'est à dire dont le rainant forme une arête dont la crête est uniligne.The fold lines according to the embodiments of the invention more particularly described are in turn simple lines, that is to say whose groove forms an edge whose ridge is one-sided.
Par collage il faut entendre un collage interdisant le mouvement relatif, c'est à dire empêchant le mouvement dans le . sens du plan des volets et panneaux, sans arrachage et délaminage.By collage, we mean a collage prohibiting relative movement, ie preventing movement in the. direction of the plane of shutters and panels, without tearing and delamination.
Par contre un tel collage peut autoriser une désolidarisation ultérieure des éléments de la boîte ainsi formée par arrachage transversal de l'un par rapport à l'autre de façon manuelle, pour libérer la coiffe de l'embase formant barguette.On the other hand, such a bonding may allow subsequent separation of the elements of the box thus formed by transversely pulling the one relative to the other manually, to release the cap of the base forming barguette.

L'invention sera mieux comprise au vu de la description qui suit des modes de réalisation donnés ci-après à titre d'exemples non limitatifs.The invention will be better understood from the description which follows of the embodiments given below by way of non-limiting examples.
Elle se réfère aux dessins qui l'accompagnent dans lesquels :It refers to the accompanying drawings in which:
Les figures IA, IB et IC montrent en perspective la boîte selon un mode de réalisation de l'invention avant, pendant et après ouverture.Figures IA, IB and IC show in perspective the box according to one embodiment of the invention before, during and after opening.
Les figures 2 et 3 sont des vues en plan d'un ensemble de découpes selon un premier mode de réalisation de l'invention, avant et après solidarisation.Figures 2 and 3 are plan views of a set of blanks according to a first embodiment of the invention, before and after joining.
Les figures 4 et 5 montrent un autre mode de réalisation de la boîte selon l'invention après et avant ouverture.Figures 4 and 5 show another embodiment of the box according to the invention after and before opening.
La figure 6 est une vue en plan d'un autre mode de réalisation d'un ensemble de découpes selon l'invention pour boîte à huit côtés.Figure 6 is a plan view of another embodiment of a set of blanks according to the invention for an eight-sided box.
La figure 7 est une vue en plan d'un autre mode de réalisation d'un ensemble selon l'invention. Les figures 8, 9 et 10 sont des vues en plan d'un autre mode de réalisation d'un ensemble de découpes selon l'invention avant collage, après collage et après pliage. Les figures IA à IC montrent une boîte d'emballage 1 de forme parallélépipédique comportant une coiffe 2 et une embase 3, de présentation des produits (non représentés) .Figure 7 is a plan view of another embodiment of an assembly according to the invention. Figures 8, 9 and 10 are plan views of another embodiment of a set of blanks according to the invention before gluing, after gluing and after folding. FIGS. 1A to 1C show a parallelepiped-shaped packaging box 1 comprising a cap 2 and a base 3 for presenting the products (not shown).
La coiffe 2 est fixée par collage sur les parois en biais 4 de l'embase 3 par des points de colle 5, la désolidarisation de la coiffe avec l'embase s 'effectuant par traction latérale 6 et arrachage vertical (flèche 7) comme indiqué sur la figure IA.The cap 2 is fixed by gluing on the angled walls 4 of the base 3 by glue points 5, the disconnection of the cap with the base being effected by lateral traction 6 and vertical tearing (arrow 7) as indicated in Figure IA.
La coiffe 2 est ensuite écartée en étant tirée vers l'avant (flèche 8) pour donner l'embase de présentation ou barquette 3 telle que représentée en figure IC.The cap 2 is then spaced by being pulled forward (arrow 8) to give the presentation base or tray 3 as shown in Figure IC.
En référence aux figures 2 et 3, l'embase 3 est obtenue à partir d'une première découpe 9 à quatre volets, la coiffe 2 étant quant à elle obtenue à partir d'une deuxième découpe 10 à trois panneaux, l'une et l'autre étant par exemple obtenue à partir d'un même flan par découpe.With reference to FIGS. 2 and 3, the base 3 is obtained from a first cut 9 with four flaps, the cap 2 being in turn obtained from a second cutout 10 with three panels, one and the other being for example obtained from the same blank by cutting.
Plus précisément, la première découpe 9 comporte une première suite 11 de quatre volets 12, 13, 14 etMore specifically, the first blank 9 comprises a first suite 11 of four shutters 12, 13, 14 and
15 terminés par une languette de fixation 16 et reliés entre eux par des premières lignes de pliage15 terminated by a fastening tab 16 and interconnected by first folding lines
17 parallèles entre elles.17 parallel to each other.
Cette première suite est munie d'un côté d'une première suite 18 de rabats 19 reliée à ladite première suite de volets par des deuxièmes lignes de pliage 20 perpendiculaires aux dites premières lignes de pliage. La deuxième découpe 10 destinée à former la coiffe de la boîte 1 comporte une deuxième suite 21 de trois panneaux 22, 23 et 24 reliés entre eux par des troisièmes lignes de pliage 25 parallèles entre elles et munies de l'autre côté d'une deuxième suite 26 de rabats 27 reliés à la deuxième suite de panneaux par des quatrièmes lignes de pliage 28.This first suite is provided on one side with a first suite 18 of flaps 19 connected to said first sequence of flaps by second fold lines 20 perpendicular to said first fold lines. The second cutout 10 intended to form the cap of the box 1 comprises a second suite 21 of three panels 22, 23 and 24 interconnected by third fold lines 25 parallel to each other and provided on the other side of a second 26 of flaps 27 connected to the second series of panels by fourth fold lines 28.
Les rabats de la première suite 18 et de la deuxième suite 26 sont par exemple rectangulaires ou sensiblement rectangulaires avec des côtés légèrement en biais pour faciliter la formation du fond et du dessus de la boîte par pliage, sans risquer d'accrocher les bords.The flaps of the first suite 18 and the second suite 26 are for example rectangular or substantially rectangular with slightly angled sides to facilitate the formation of the bottom and top of the box by folding, without the risk of hanging edges.
Selon le mode de réalisation de l'invention plus particulièrement décrit, la première suite 11 de volets comporte un premier volet rectangulaire 12 destiné à former la paroi de fond 29 (Cf. figure IC) de l'embase.According to the embodiment of the invention more particularly described, the first 11 flap suite comprises a first rectangular flap 12 for forming the bottom wall 29 (see Figure IC) of the base.
Il est muni de l'autre côté de la première suite 18 de rabats, d'un rabat arrachable 30 relié au volet 12 par une ligne de jonction perforée 31.-It is provided on the other side of the first flap suite 18, with a tear-off flap 30 connected to the flap 12 by a perforated junction line 31.
Une partie découpée 32 dans la partie du volet 12 en forme de poignée est prévue pour faciliter l'arrachage manuel pour un utilisateur selon la flèche 8 de la figure IB.A cut portion 32 in the portion of the flap 12 in the form of a handle is provided to facilitate manual tearing for a user according to the arrow 8 of Figure IB.
La première suite de volets 18 comporte également deux volets 13 et 15, symétriques par rapport à une droite, non adjacents, trapézoïdaux, destinés à former les parois latérales 4 de l'embase et comportant respectivement chacun un bord intérieur 33,34, dirigé au moins en partie en biais vers le volet 14, central, de hauteur réduite destiné à former la paroi 35 (Cf. figure IC) de face avant de l'embase 3.The first sequence of flaps 18 also comprises two flaps 13 and 15, symmetrical with respect to a straight line, non-adjacent, trapezoidal, intended to form the side walls 4 of the base and respectively comprising respectively an inner edge 33, 34, directed to the at least in part towards Central Panel 14, of reduced height intended for form the wall 35 (see Figure IC) front face of the base 3.
Par hauteur réduite il faut entendre une paroi de hauteur inférieure à celle de la paroi de fond, par exemple 5 à 10 fois inférieure.Reduced height means a wall of height less than that of the bottom wall, for example 5 to 10 times lower.
La deuxième suite de panneaux 21 comprend quant à elle les deux panneaux d'extrémités 22 et 24 trapézoïdaux, comprenant des bord extérieurs en biais 35, 36 de forme complémentaire à celle des bords intérieurs 33, 34 de la première découpe, et le panneau central rectangulaire 23 par exemple de même hauteur que le volet 12.The second series of panels 21 comprises, in turn, the two trapezoidal end panels 22 and 24, comprising external angled edges 35, 36 of shape complementary to that of the inner edges 33, 34 of the first cut, and the central panel rectangular 23 for example of the same height as the flap 12.
Par la suite, on utilise les mêmes numéros de référence pour désigner les mêmes éléments ou des éléments similaires .Subsequently, the same reference numbers are used to designate the same elements or similar elements.
La figure 3 montre l'ensemble de deux découpes collées l'une sur l'autre, avec un recouvrement suffisant pour autoriser un collage aux points de colle 37 au niveau des bords intérieurs et extérieurs en vis à vis des volets et panneaux trapézoïdaux, lorsque la ligne de pliage perforée 31 et les quatrièmes lignes de pliage 28 sont alignées ou sensiblement alignées comme représenté sur les figures . Par sensiblement alignés, on entend une disposition qui permet une meilleure fermeture des rabats du dessus par surchappement des uns sur les autres, de façon à former le dessus des boîtes comme montré sur les figures IA à IC ou 4 et 5. Pour former en effet le dessus de la boîte une fois celle-ci remplie, on plie les petits rabats 27 correspondants des deux volets trapézoïdaux 22 et 24 puis on colle dessus les deux grands rabats 27 et 30 correspondants d'une part au panneau central 23 de la deuxième découpe et d' autre part au volet de fond 12 de la première découpe pour finir la coiffe arrachable. (Cf. notamment figure 4 et figure IC) par l'utilisateur par introduction de sa main et/ou de ses doigts au travers de la portion évidée 32.FIG. 3 shows the set of two cutouts glued one on the other, with sufficient overlap to allow bonding at the glue points 37 at the inner and outer edges facing trapezoidal flaps and panels, when the perforated fold line 31 and the fourth fold lines 28 are aligned or substantially aligned as shown in the figures. By substantially aligned, is meant an arrangement that allows a better closure of the top flaps by over-escaping each other, so as to form the top of the boxes as shown in Figures IA to IC or 4 and 5. To form indeed the top of the box once filled, we fold the corresponding small flaps 27 of the two trapezoidal flaps 22 and 24 and then glue on the two large flaps 27 and 30 corresponding firstly to the central panel 23 of the second blank and secondly to the bottom flap 12 of the first blank to finish the torn cap. (See in particular FIG. 4 and FIG. 1C) by the user by introducing his hand and / or his fingers through the recessed portion 32.
Des petits orifices 33' dans les parois 22 et 23, centrés permettent quant à eux de faciliter le décollement des parois latérales des coiffe et embase.Small holes 33 'in the walls 22 and 23, centered allow them to facilitate the detachment of the side walls of the cap and base.
On a représenté sur les figures 4 et 5 un autre mode de réalisation d'une boîte 34 selon l'invention pour lequel cette fois-ci la coiffe 35 est collée sur l'extérieur 36 des parois en biais trapézoïdales 37 de l'embase 38 et non sur la partie interne comme représenté sur la figure 1 A.FIGS. 4 and 5 show another embodiment of a box 34 according to the invention for which, this time, the cap 35 is glued to the outside 36 of the trapezoidal side walls 37 of the base 38 and not on the inner part as shown in Figure 1 A.
La figure 6 montre un autre mode de réalisation d'un flan 39 à huit côtés selon l'invention.Figure 6 shows another embodiment of an eight-sided blank 39 according to the invention.
Dans ce mode de réalisation l'ensemble de découpes 40, 41 est obtenu à partir du même flan 39 découpé selon la ligne 42 pour obtenir les bords extérieurs en biais des volets et panneaux trapézoïdaux des deux découpes selon l'invention, la deuxième découpe étant ensuite décalée pour permettre le collage. Des volets et panneaux intermédiaires 43, 44 sont par ailleurs prévus pour former les coins coupés du flan à huit cotés.In this embodiment, the set of cuts 40, 41 is obtained from the same blank 39 cut along the line 42 to obtain the external edges at an angle of the flaps and trapezoidal panels of the two blanks according to the invention, the second blank being then shifted to allow gluing. Flaps and intermediate panels 43, 44 are also provided to form the cut corners of the eight-sided blank.
Ici encore et de façon avantageuse, chacun des panneaux trapézoïdaux 22, 24 comprend des évidements 33 à proximité des points de collage pour faciliter le décollage des parois trapézoïdales des volets trapézoïdaux manuellement par simple traction par exemple comme montré sur la figure IA. Dans les modes de réalisation décrits ci-avant les parties inférieures 45 des troisièmes lignes 25 de pliage en vis à vis des premières lignes de pliage 17 du petit volet 14 sont soit découpées soit écrasées de façon à permettre lors de l'enrobage de l'ensemble collé autour d'un mandrin une certaine souplesse notamment suffisante pour empêcher l'arrachage des points de colle.Again and advantageously, each of the trapezoidal panels 22, 24 comprises recesses 33 near the bonding points to facilitate the takeoff of the trapezoidal walls trapezoidal flaps manually by simple traction for example as shown in Figure IA. In the embodiments described above, the lower portions 45 of the third fold lines 25 facing the first fold lines 17 of the small shutter 14 are either cut or crushed so as to allow the coating of the set glued around a mandrel a certain flexibility including sufficient to prevent tearing glue points.
On a représenté sur la figure 7 un autre mode de réalisation d'un ensemble 46 où le rabat 30 relié par une ligne perforée 31 n' est pas solidaire du volet 12 formant le fond de l'embase mais appartient à la deuxième découpe 10 munie d'un quatrième panneau 47 comprenant sur sa partie supérieure ledit rabat, ce qui implique de prévoir des points de collage supplémentaires 48 lors de l'alignement de la ligne 31 avec la ligne supérieure 49 en vis à vis dudit volet de fond de l'embase.FIG. 7 shows another embodiment of an assembly 46 in which the flap 30 connected by a perforated line 31 is not integral with the flap 12 forming the bottom of the base but belongs to the second blank 10 provided with a fourth panel 47 comprising on its upper part said flap, which involves providing additional bonding points 48 during alignment of the line 31 with the upper line 49 opposite said bottom flap of the base.
On a représenté sur les figures 8 à 10 un autre mode de réalisation d'un ensemble 50 selon 1' invention permettant cette fois-ci non plus une formation de la boîte par enrobage autour d'un mandrin comme plus particulièrement décrit en référence aux figures précédentes, mais un emballage plié collé 51.FIGS. 8 to 10 show another embodiment of an assembly 50 according to the invention, this time no longer forming the box by coating around a mandrel as more particularly described with reference to FIGS. previous, but a folded package glued 51.
Plus précisément, la figure 8 montre un ensemble de deux découpes 9, 10 comportant une première découpe 9 à quatre volets 12, 13, 14, 15 et une deuxième découpe 10 à trois panneaux 22, 23, 24, la partie inférieure 51 des troisièmes lignes de pliage 25 étant cette fois-ci non pas pliée, écrasée ou découpée mais ajourée, par exemple par un petit évidement 52 rectangulaire qui va permettre le rattrapage des jeux lors du pliage / collage.More precisely, FIG. 8 shows a set of two cutouts 9, 10 having a first cut 9 with four flaps 12, 13, 14, 15 and a second cutout 10 with three panels 22, 23, 24, the lower portion 51 of the thirds fold lines 25 being this time not folded, crushed or cut but perforated, for example by a small recess 52 rectangular which will allow the catching games during folding / gluing.
Sur la figure 9 on a représenté la deuxième découpe 10 mise en superposition de la première découpe 9, le bord inférieur 53 du panneau 23 étant sensiblement superposé à la ligne de pliage 20 comme également décrit ci-avant en référence aux figures précédentes .In Figure 9 there is shown the second blank 10 superimposed the first blank 9, the lower edge 53 of the panel 23 being substantially superimposed on the fold line 20 as also described above with reference to the previous figures.
Ces évidements ou encoches 52, nécessaires au rattrapage des surépaisseurs, sont notamment une première encoche 52 prévue pour le pliage à 90° d'une première ligne des troisièmes lignes de pliage (à la réouverture de la caisse) et une deuxième encoche, celle-ci plus importante, nécessaire au rattrapage des surépaisseurs lors du pliage à 180° de la troisième ligne de pliage, avant livraison de la caisse à plat comme montré en 51 sur la figure 10.These recesses or notches 52, necessary to compensate for the extra thicknesses, include a first notch 52 provided for the bending at 90 ° of a first line of the third fold lines (at the reopening of the body) and a second notch, that more important, necessary to catch overthicknesses at the 180 ° folding of the third fold line, before delivery of the box flat as shown at 51 in Figure 10.
Celle-ci peut ensuite être ouverte comme une caisse américaine sur une ouvreuse de caisse traditionnelle, ou encore manuellement.This can then be opened as an American fund on a traditional cashier, or manually.
En ce qui concerne la figure 6 qui va permettre donc d'obtenir un emballage à huit côtés, on notera qu' il est prévu un décalage entre la ligne de pliage de la première découpe correspondant au premier petit côté et celui de l'embase de la coiffe correspondante, par exemple de x mm permettant justement le rattrapage après superposition.With regard to FIG. 6, which will therefore make it possible to obtain an eight-sided package, it will be noted that an offset is provided between the fold line of the first cut corresponding to the first short side and that of the base of the corresponding cap, for example of x mm just for catching after superposition.
Ici l' insert peut être situé à l'intérieur de la caisse ou à l'extérieur en option ce qui implique à ce moment là des décalages différents.Here the insert can be located inside the box or outside optional which implies at that moment different offsets.
On va maintenant décrire en référence aux figures 8 à 10 la fabrication, le fonctionnement et l'utilisation selon un mode de réalisation de l' invention.We will now describe with reference to FIGS. 8 to 10 the manufacture, operation and the use according to one embodiment of the invention.
A partir d'un flan 50, on découpe les deux découpes 9 et 10 qu'on sépare l'une de l'autre puis on les superpose en les désolidarisant, après avoir appliqué les points de collage 37 en une et/ou deux parties à proximité des orifices 33 de façon à permettre ensuite un décollage facile de la coiffe par rapport à l'embase. Puis on jonctionne l'ensemble ainsi constitué avec la pâte ou languette de collage 16, par repliage àStarting from a blank 50, the two blanks 9 and 10 are cut out and separated from each other and then superposed by separating them after having applied the bonding points 37 in one and / or two parts. near the orifices 33 so as to then allow easy takeoff of the cap relative to the base. Then the assembly thus formed is joined with the adhesive paste or tongue 16, by folding to
180° de deux lignes de pliage verticales.180 ° of two vertical fold lines.
Une fois chez le conditionneur, l'ensemble de deux découpes peut être ouvert manuellement ou automatiquement selon la même séquence que pour une caisse américaine.Once at the conditioner, the set of two cuts can be opened manually or automatically in the same sequence as for a US fund.
Les rabats supérieurs et inférieurs sont plies quant à eux à 90° puis collés ou scotchés les uns sur les autres. Lors de la mise en rayon de la boite ainsi obtenue, les trois panneaux avant sont retirés selon la séquence suivante.The upper and lower flaps are folded at 90 ° and then glued or taped on each other. When the box thus obtained is shelved, the three front panels are removed in the following sequence.
Après mise en place de la boite sur l'étagère, et en référence à la figure IA, on écarte les parois au niveau des ouvertures latérales pour arracher les points de colle 5.After placing the box on the shelf, and with reference to FIG IA, we remove the walls at the side openings to tear the points of glue 5.
On déchire ensuite (figure IB) les points d'attache de la ligne perforée 31 du rabat supérieurThe points of attachment of the perforated line 31 of the upper flap are then torn (FIG.
30 attenant à l'embase, en attrapant manuellement la poignée découpée 32. On arrache alors la coiffe 2 par un mouvement latéral (flèche 8) puis on dégage complètement les trois panneaux de ce qui constituait un insert, pour obtenir la libération complète de l'embase 3 et la présentation claire et ordonnée des produits directement sur l'étagère.30 is attached to the base, by catching the cut handle 32 manually. The cap 2 is then pulled off by a lateral movement (arrow 8) and the three panels are completely freed from what constituted an insert, to obtain the complete release of the base 3 and the clear and orderly presentation of products directly on the shelf.
On évite ainsi les déplacements d'une embase comportant des produits qui peuvent glisser ou se déplacer lors d'un tel transport.This avoids the movements of a base with products that can slide or move during such transport.
En effet, l'embase est directement mise en rayon, et l'enlèvement de la coiffe ne se fait qu'une fois que l'ensemble n'est plus susceptible de bouger.Indeed, the base is directly shelved, and the removal of the cap is done once the whole is more likely to move.
Dans un autre mode de réalisation, où les deux découpes sont enrobées autour d'un mandrin après collage, on réalise les opérations suivantes.In another embodiment, where the two blanks are coated around a mandrel after gluing, the following operations are carried out.
On découpe et/ou on écrase les troisièmes lignes de pliage 25 en partie basse 45 sur les portions agencées pour être placées en vis à vis des premières lignes de pliage correspondantes.The third fold lines 25 are cut and / or crushed in the lower part 45 on the portions arranged to be placed opposite the corresponding first fold lines.
Puis en encolle les deux volets trapézoïdaux opposés non adjacents.Then glue the two opposite non-adjacent trapezoidal flaps.
On place ensuite la deuxième découpe sur la première découpe, les trois lignes de pliage découpées ou écrasées de la deuxième découpe étant sensiblement alignées par rapport au première ligne de pliage de la première découpe.The second cut is then placed on the first cut, the three cut or creased fold lines of the second cut being substantially aligned with respect to the first fold line of the first cut.
Il s'ensuit une superposition des zones coupées ou écrasées des troisièmes lignes de pliage avec les premières lignes de pliage sur toute leur hauteur et dans un mode de réalisation sur une hauteur un peu supérieure, de sorte que les zones dépassent au dessus du bord sans rabat de la première découpe.It follows a superposition of the cut or crushed areas of the third fold lines with the first fold lines over their entire height and in an embodiment on a slightly higher height, so that the areas exceed above the edge without flap of the first cut.
On applique alors la deuxième découpe sur la première découpe pour solidariser ensemble les deux panneaux et les deux volets non adjacents de façon à ce que tout mouvement translatif dans le sens du plan des flans soit rendu impossible sans destruction c'est à dire sans arrachage et/ou délaminage d'un des deux cartons .The second cut is then applied to the first blank to secure the two panels and the two non-adjacent flaps together so that any translational movement in the direction of the blank plane is made impossible without destruction. that is to say without tearing and / or delamination of one of the two boxes.
On vient ensuite positionner cet ensemble de découpes sous un mandrin, ici sous une face non encollée et on rabat l'ensemble de découpes en enroulant autour du volume déterminé du mandrin, sans glissement de la deuxième découpe par rapport à la première découpe, sauf au niveau des derniers panneaux. Découpes ou écrasements effectués sur les portions des troisièmes lignes de pliage' selon le mode de réalisation de l'invention décrit ci-avant permettent alors la formation sans pli, écrasement ou arrachement des volets et panneaux de la boîte. Mais un autre mode de réalisation est également possible lors de l'enrobage autour d'un mandrin dans le cas où cette fois-ci on autorise le glissement par les points de collage (visqueux) , auquel cas les rattrapages vont pouvoir se faire grâce à un tel glissement.This set of blanks is then positioned under a mandrel, here under an unsized face and the set of blanks is folded by wrapping around the determined volume of the mandrel, without sliding of the second blank with respect to the first blank, except for level of the last panels. Cutting or crushing performed on the portions of the third fold lines ' according to the embodiment of the invention described above then allow the formation without crease, crushing or tearing shutters and panels of the box. But another embodiment is also possible when wrapping around a mandrel in the case where this time is allowed to slip by the sticking points (viscous), in which case the catching up will be done through such a slip.
Comme il va de soi et comme il résulte également de ce qui précède, la présente invention n'est pas limitée aux modes de réalisation plus particulièrement décrits. Elle en embrasse au contraire toutes les variantes et notamment celles où la résistance du carton des première et deuxième découpes n'est pas la même. As is obvious and as also follows from the above, the present invention is not limited to the embodiments more particularly described. It encompasses all variants and especially those where the strength of the carton of the first and second cuts is not the same.
