Abstract
Description
La présente invention concerne une boîte de section polygonale en une matière en feuille de carton ondulé double face ou analogue comportant un fond, un dessus et une paroi latérale externe, ladite paroi latérale externe étant constituée de plusieurs panneaux, à savoir deux panneaux dits d'extrémité reliés d'un côté l'un à l'autre par l'intermédiaire d'une languette de fixation et reliés respectivement de l'autre côté, directement par une ligne de pliage, à une suite d'au moins deux panneaux intermédiaires, chaque panneau intermédiaire étant lui-même relié directement par une ligne de pliage à chacun des deux panneaux qui lui sont adjacents de part et d'autre.The present invention relates to a box of polygonal cross-section made of a sheet material of double-sided corrugated cardboard or the like comprising a bottom, a top and an external side wall, said external side wall consisting of several panels, namely two so-called panels. end connected on one side to the other by means of a fixing tab and connected respectively on the other side, directly by a fold line, to a series of at least two intermediate panels, each intermediate panel itself being directly connected by a fold line to each of the two panels which are adjacent to it on either side.
L'invention concerne également un procédé de fabrication d'une telle boîte.The invention also relates to a method of manufacturing such a box.
On a constaté que, selon le type de produits qu'elles sont destinées à contenir, de telles boîtes ne présentent pas toujours la rigidité nécessaire, notamment au niveau de leur paroi latérale. Augmenter l'épaisseur de la matière en feuille utilisée pour former de telles boîtes ne constitue pas une solution entièrement satisfaisante dans la mesure où, comme ces boîtes sont généralement réalisées à partir d'un flan unique, cela revient à augmenter l'épaisseur de paroi de la boîte en des endroits où cela n'est pas forcément nécessaire pour les besoins recherchés, comme par exemple le dessus ou le fond de celle-ci. La consommation de matière, le coût de la boîte et son poids augmentent donc inutilement.It has been found that, depending on the type of products they are intended to contain, such boxes do not always have the necessary rigidity, especially at their side wall. Increasing the thickness of the sheet material used to form such boxes is not a completely satisfactory solution since, since these boxes are generally made from a single blank, this amounts to increasing the wall thickness of the box in places where this is not necessarily necessary for the needs sought, such as the top or the bottom thereof. Material consumption, the cost of the box and its weight therefore unnecessarily increase.
On connaît déjà (US-A-5.108.028) des boîtes en carton ondulé muni d'un renfort interne solidarisé par collage. Ces boîtes sont obtenues à partir d'un flan sur lequel le renfort est collé, à plat et nécessitent de prévoir des parties intermédiaires entre panneaux du flan présentant un pli supplémentaire de rattrapage d'épaisseur, pour permettre la formation ultérieure de la boîte par pliage. Une telle disposition, qui permet le montage et le démontage de la caisse, nécessite cependant un montage manuel et un ajustage du renfort sur le flan lors du collage qui n'est pas simple à mettre en oeuvre.We already know (US-A-5,108,028) corrugated boxes provided with an internal reinforcement secured by gluing. These boxes are obtained from a blank on which the reinforcement is glued, flat and require the provision of intermediate parts between panels of the blank having an additional fold of thickness take-up, to allow the subsequent formation of the box by folding . Such an arrangement, which allows the assembly and disassembly of the box, however requires manual assembly and adjustment of the reinforcement on the blank during bonding which is not simple to implement.
On connaît également (EP-A-0.231.082 ; US-A-2.710.134) des caisses en carton ondulé à paroi renforcée par une épaisseur simple face de carton ondulé encollée automatiquement sur une feuille double face, aux endroits nécessitant un renfort. Si une telle disposition permet un pliage en souplesse pour former la caisse, elle est cependant compliquée et coûteuse à mettre en oeuvre.Also known (EP-A-0.231.082; US-A-2.710.134) corrugated cardboard boxes with wall reinforced by a single-sided thickness of corrugated cardboard automatically glued on a double-sided sheet, in places requiring reinforcement. If such an arrangement allows a flexible folding to form the box, it is however complicated and expensive to implement.
On connaît également (US-A-3.960.312) une caisse à renfort interne tubulaire non encollé que l'on vient glisser dans la caisse préformée de forme tubulaire. La solidité et la rigidité d'une telle caisse n'est pas bonne.There is also known (US-A-3,960,312) a box with non-glued tubular internal reinforcement which has just been slid into the preformed box of tubular shape. The strength and rigidity of such a box is not good.
On connaît également (US-A-4.053.102) des caisses en carton plat à paroi renforcée par une deuxième épaisseur.Also known (US-A-4,053,102) are flat cardboard boxes with walls reinforced by a second thickness.
Si une telle caisse, de paroi mince, ne pose donc pas le problème du pli de rattrapage, elle ne présente cependant pas les mêmes avantages que le carton ondulé, notamment concernant la tenue à la pression dans le sens de la feuille.If such a box, of thin wall, does not therefore pose the problem of the take-up fold, it does not however have the same advantages as the corrugated cardboard, in particular concerning the pressure resistance in the direction of the sheet.
La présente invention vise à fournir une boîte répondant mieux que celles antérieurement connues aux exigences de la pratique, notamment en ce qu'elle propose une caisse très rigide, consolidée de façon simple et aisée à mettre en oeuvre, en automatique.The present invention aims to provide a box that better meets those previously known to the requirements of practice, in particular in that it offers a very rigid body, consolidated in a simple and easy to implement, automatic.
Pour ce faire, la caisse est formée par enroulement ou plaquage successif d'au moins deux feuilles en carton ondulé sur un mandrin, en utilisant par exemple un appareil de montage tel que décrit dans le document FR-A-2.629.012.To do this, the box is formed by winding or successively plating at least two sheets of corrugated cardboard on a mandrel, for example using a mounting device as described in document FR-A-2,629,012.
Dans ce but l'invention propose notamment une boîte de section polygonale comportant un fond, un dessus et une paroi latérale externe, en feuille de carton ondulé double face ou analogue, ladite paroi latérale externe étant constituée de plusieurs panneaux, à savoir deux panneaux dits d'extrémité reliés d'un côté l'un à l'autre par l'intermédiaire d'une languette de fixation et reliés respectivement de l'autre côté, directement par une ligne de pliage, à une suite d'au moins deux panneaux intermédiaires, chaque panneau intermédiaire étant lui-même relié directement par une ligne de pliage à chacun des deux panneaux qui lui sont adjacents de part et d'autre,
caractérisée en ce que ladite boîte comprend un renfort interne constitué par une feuille en carton ondulé double face ou analogue, solidarisé par collage sur une partie au moins de sa surface aux faces internes d'au moins deux panneaux correspondants de ladite paroi latérale, la ou les arêtes dudit renfort coïncidant respectivement avec la ou les lignes de pliages correspondantes desdits panneaux.To this end, the invention notably proposes a box of polygonal cross section comprising a bottom, a top and an external side wall, of double-sided corrugated cardboard sheet or the like, said external side wall consisting of several panels, namely two so-called panels. end connected on one side to the other by means of a fixing tab and connected respectively on the other side, directly by a fold line, to a series of at least two panels intermediary, each intermediate panel itself being directly connected by a fold line to each of the two panels which are adjacent to it on either side,
characterized in that said box comprises an internal reinforcement constituted by a sheet of corrugated double-sided cardboard or the like, secured by gluing on at least part of its surface to the internal faces of at least two corresponding panels of said side wall, the or the edges of said reinforcement respectively coinciding with the corresponding fold line or lines of said panels.
Une telle caisse ne présente donc pas de pli de rattrapage contrairement à celles de l'art antérieur.Such a box therefore does not have a catch-up fold unlike those of the prior art.
Autrement dit, la boîte selon l'invention présente une superposition exacte des lignes de pliage du flan externe sur les arêtes du renfort interne préformé, arêtes formées autour des lignes de pliage dudit renfort interne.In other words, the box according to the invention has an exact superposition of the fold lines of the external blank on the edges of the preformed internal reinforcement, edges formed around the fold lines of said internal reinforcement.
Une telle disposition a été rendue possible grâce au montage autour d'un mandrin, les parois latérales et le fond de la caisse étant pliés sur le renfort interne, lui-même formé autour dudit mandrin.Such an arrangement has been made possible by mounting around a mandrel, the side walls and the bottom of the box being folded on the internal reinforcement, itself formed around said mandrel.
Dans un mode de réalisation avantageux, ledit renfort interne est constitué par une succession de volets reliés les uns aux autres par des lignes de pliage et constituant une ceinture de renfort interne correspondant à ladite paroi latérale, chacun des volets de la ceinture de renfort étant solidarisé, sur une partie au moins de sa surface, à la face interne du panneau correspondant de ladite paroi latérale.In an advantageous embodiment, said internal reinforcement consists of a succession of flaps connected to each other by fold lines and constituting an internal reinforcement belt corresponding to said side wall, each of the flaps of the reinforcement belt being secured , on at least part of its surface, to the internal face of the corresponding panel of said side wall.
Dans ce cas, ladite ceinture de renfort interne peut être associée, de plus, à un panneau de fond en une seule pièce, solidarisé à ladite boîte.In this case, said internal reinforcing belt can be associated, in addition, with a bottom panel in one piece, secured to said box.
En particulier, dans le cas où la boîte présente une section transversale rectangulaire ou carrée, ladite ceinture de renfort interne comporte quatre volets correspondant chacun à un panneau de ladite paroi latérale.In particular, in the case where the box has a rectangular or square cross section, said internal reinforcement belt has four flaps each corresponding to a panel of said side wall.
Dans la cas d'une boîte de section transversale rectangulaire ou carrée à coins coupés, la ceinture de renfort interne présente par contre huit volets correspondant de même chacun à un panneau de ladite paroi latérale.In the case of a rectangular or square cross-section box with cut corners, the belt internal reinforcement, on the other hand, has eight flaps corresponding in the same way each to a panel of said side wall.
Dans un autre mode de réalisation avantageux, le renfort interne comporte un volet central, formant panneau de fond pour ladite boîte, relié directement, sur au moins un côté ou sur au moins deux côtés opposés de celui-ci, à un volet latéral par une ligne de pliage, lesdits volets latéraux étant, chacun, solidarisé, sur une partie au moins de leur surface, à un panneau correspondant à ladite paroi latérale.In another advantageous embodiment, the internal reinforcement comprises a central flap, forming a bottom panel for said box, connected directly, on at least one side or on at least two opposite sides thereof, to a side flap by a fold line, said side flaps each being secured, on at least part of their surface, to a panel corresponding to said side wall.
Avantageusement, ledit renfort interne présente, en coupe transversale, une forme de U, et est constitué par trois volets dont le volet central forme, au moins particulièrement, le fond de ladite boîte et dont les deux volets latéraux sont solidarisés aux faces internes de panneaux opposés correspondants de ladite paroi latérale.Advantageously, said internal reinforcement has, in cross section, a U shape, and is constituted by three flaps whose central flap forms, at least particularly, the bottom of said box and whose two side flaps are secured to the internal faces of panels corresponding opposites of said side wall.
Avantageusement, la solidarisation entre les différents panneaux et volets peut être faite sur toute leur surface, ou sur une partie seulement, par exemple sur une surface en forme de bande périphérique de l'ordre de 1 à 3 cm sur le pourtour desdits volets ou panneaux.Advantageously, the connection between the various panels and shutters can be made over their entire surface, or over only a part, for example on a surface in the form of a peripheral strip of the order of 1 to 3 cm around the periphery of said shutters or panels. .
Dans un mode de réalisation avantageux, au moins deux panneaux en vis à vis de la paroi latérale comprennent des rabats inférieurs reliés directement auxdits panneaux par une ligne de pliage unique, c'est-à-dire sans plis de rattrapage, et un fond collé sur lesdits rabats pour constituer une surface interne lisse pour la boîte.In an advantageous embodiment, at least two panels facing the side wall include lower flaps connected directly to said panels by a single fold line, that is to say without take-up folds, and a glued bottom on said flaps to form a smooth internal surface for the box.
Avantageusement la boîte comprend deux ou plusieurs renforts internes en feuille de carton ondulé double face, superposés sur au moins une portion de leurs surfaces, solidaires entre eux sur au moins une partie de, ou sur toute, ladite portion de surface de contact entre lesdits renforts.Advantageously, the box includes two or more internal reinforcements made of cardboard sheet. corrugated double face, superimposed on at least a portion of their surfaces, integral with each other on at least a part of, or over all, said portion of contact surface between said reinforcements.
La boîte peut aussi comprendre un renfort interne et un renfort externe en feuille de carton ondulé double face, toujours sans présenter de plis de rattrapage, ledit renfort étant solidarisé par collage sur une partie au moins de leur surface de contact avec les parois latérales et/ou le fond.The box may also include an internal reinforcement and an external reinforcement made of double-sided corrugated cardboard sheet, always without presenting any folds of take-up, said reinforcement being secured by gluing on at least part of their contact surface with the side walls and / or the bottom.
Avantageusement, le sens des cannelures de la paroi latérale de la boîte peut être perpendiculaire au sens des cannelures du renfort interne.Advantageously, the direction of the grooves in the side wall of the box can be perpendicular to the direction of the grooves in the internal reinforcement.

Les figures 10 à 13 montrent différents flans pour la réalisation d'une boîte du type montré sur la figure 9.Figures 10 to 13 show different blanks for making a box of the type shown in Figure 9.
La figure 14 est une vue en perspective et coupe transversale d'une boîte à simple fond collé, réalisée grâce à la méthode selon l'invention.Figure 14 is a perspective view and cross section of a box with a single glued bottom, produced by the method according to the invention.
Sur la figure 1, on a représenté un premier exemple de réalisation d'une boîte 1 conforme à l'invention, ayant dans cet exemple une section rectangulaire. Toutefois, on notera que l'invention s'applique, bien entendu et tout aussi bien, à des boîtes ayant d'autres sections polygonales.In Figure 1, there is shown a first embodiment of a
La boîte selon l'invention est réalisée en une matière en feuille du type carton ondulé ou analogue, par exemple et notamment en carton ondulé double face présentant une certaine épaisseur, par exemple de 1 à 5 mm, ou en carton ondulé dit double-double d'épaisseur pouvant atteindre 8 mm, et comporte une paroi latérale 2 constituée d'une pluralité de panneaux 3 (quatre dans cet exemple) reliés directement c'est-à-dire sans ligne de pliage de rattrapage en épaisseur supplémentaire, par des lignes de pliage 4, ainsi que d'un rabat ou languette 5 permettant la solidarisation des "premier" et "dernier" panneaux 3 de la ceinture latérale 2 (figures 2 et 3). Par ailleurs, la boîte 1 présente des premiers volets 6 formant le fond de la boîte 1 et des seconds volets 7 formant le dessus de celle-ci, les premiers et seconds volets 6 et 7 étant reliés à la ceinture latérale 2 par les lignes de pliage respectives 8 et 9.The box according to the invention is made of a sheet material of the corrugated cardboard or similar type, for example and in particular of double-sided corrugated cardboard having a certain thickness, for example from 1 to 5 mm, or of said corrugated cardboard double-double thickness up to 8 mm, and has a
Comme on le voit clairement sur la figure 1, la boîte 1 comprend un renfort interne 10, constitué d'une matière en feuille, en carton ondulé double face ou analogue, solidarisé, sur une partie de sa surface par exemple de l'ordre de 1/10e, ou compris entre 5/100e et 1/3 de ladite surface, respectivement aux faces internes des panneaux 3 correspondants de la paroi latérale 2.As can be clearly seen in FIG. 1, the
Dan sun mode de réalisation particulièrement avantageux des boîtes selon l'invention, le renfort interne est collé sur les parois de la façon suivante. La colle est appliquée verticalement, sous forme de traits ou cordons verticaux de faible épaisseur ou d'épaisseur comprise entre 1 mm et 5 à 10 mm, continus ou discontinus, avantageusement aux emplacements de la boîte qui subissent la plus forte compression lors d'un empilage des boîtes les unes sur les autres et suivant la disposition dudit empilage.In a particularly advantageous embodiment of the boxes according to the invention, the internal reinforcement is bonded to the walls in the following manner. The glue is applied vertically, in the form of vertical lines or cords of small thickness or thickness between 1 mm and 5 to 10 mm, continuous or discontinuous, advantageously at the locations of the box which undergo the greatest compression during a stacking boxes on top of each other and according to the arrangement of said stacking.
Avantageusement, il est par exemple prévu un ou plusieurs cordons sur la hauteur de la boîte à une distance comprise entre 25 mm et 80 mm de l'arête, par exemple deux cordons, l'un à 25 mm et l'autre à 80 mm, ces distances dépendant par ailleurs de la forme et de la dimensions de la boîte et pouvant être adaptées par l'homme du métier.Advantageously, it is for example provided one or more cords on the height of the box at a distance between 25 mm and 80 mm from the edge, for example two cords, one at 25 mm and the other at 80 mm , these distances depending moreover on the shape and the dimensions of the box and can be adapted by a person skilled in the art.
Plus particulièrement, dans l'exemple montré sur la figure 1, le renfort interne 10 est constitué par une succession de volets 11 reliés directement les uns aux autres par des lignes de pliage 12 et constituant une ceinture de renfort interne correspondant à la paroi latérale 2. Un rabat 13 permet de solidariser les "premier" et "dernier" volets de la ceinture de renfort 10. Chacun des volets 11 de la ceinture de renfort 10 est solidarisé, sur une partie de sa surface, par collage, à la face interne du panneau 3 correspondant de la paroi latérale 2, la surface de chaque volet 11 correspondant à la surface du panneau 3 auquel il est solidarisé.More particularly, in the example shown in FIG. 1, the
Comme on le voit sur la figure, les lignes de pliage 4 de la paroi latérale de la boîte sont parfaitement superposées aux lignes de pliage 12 du renfort.As seen in the figure, the
La figure 2 montre le flan 1, et le renfort interne 10, à partir desquels peut être réalisée, par pliage, la boîte 1 montrée sur la figure 1.FIG. 2 shows the blank 1, and the
Les dimensions relatives, et notamment les distances entre lignes de pliage sont calculées au préalable par exemple par informatique (CAO/DAO), de façon à permettre les superpositions exactes des lignes lors du montage.The relative dimensions, and in particular the distances between fold lines are calculated beforehand, for example by computer (CAD / CAM), so as to allow the exact superimpositions of the lines during assembly.
Sur la figure 3, on a représenté un flan pour la réalisation d'une boîte du type montré sur la figure 1, mais présentant une section rectangulaire à coins coupés, c'est-à-dire dont la paroi latérale 2 présente huit panneaux 3. Dans ce cas, la ceinture de renfort interne 10 présente, de même, huit volets 11.In Figure 3, there is shown a blank for the production of a box of the type shown in Figure 1, but having a rectangular section with cut corners, that is to say whose
L'exemple de réalisation de la boîte 1 montré sur la figure 4 se distingue de celui de la figure 1 par le fait que, dans ce cas, la ceinture de renfort interne 10 est associée à un panneau de fond 14, en une seule pièce, solidarisé à la boîte 1.The embodiment of the
Cette dernière présente alors, intérieurement, un fond lisse, évitant de marquer éventuellement les produits qu'elle est destinée à contenir.The latter then has, internally, a smooth bottom, avoiding possibly marking the products that it is intended to contain.
Par ailleurs, les volets de fond 6 peuvent alors ne constituer qu'une partie du fond de la boîte 1, comme on le voit clairement sur la figure 4 notamment. La face externe du panneau 14, de forme rectangulaire, est solidarisée par collage, aux volets 6.Furthermore, the bottom flaps 6 can then constitute only part of the bottom of the
La figure 5 montre le flan 1, et la ceinture de renfort interne 10 et le panneau de fond 14 qui pourrait éventuellement être relié à l'un des volets 11 par une ligne de pliage, à partir desquels peut être réalisée, par pliage, la boîte 1 montrée sur la figure 4.FIG. 5 shows the blank 1, and the
Dans le cas du fond relié par une ligne de pliage à un des volets, cette ligne de pliage est parfaitement superposée à la ligne 8 dans la boîte montée.In the case of the bottom connected by a fold line to one of the flaps, this fold line is perfectly superimposed on
La figure 6 montre un flan ne se différenciant du précédent (figure 5) que par la configuration de deux premiers volets 6 (opposés lorsque la boîte est mise en forme), c'est-à-dire présentant une partie rectangulaire prolongeant la configuration de "base" des volets.Figure 6 shows a blank differing from the previous one (Figure 5) only by the configuration of the first two flaps 6 (opposite when the box is shaping), that is to say having a rectangular part extending the "basic" configuration of the flaps.
Sur les figures 7 et 8, on a représenté deux flans pour la réalisation d'une boîte du type montré sur la figure 4, mais présentant une section rectangulaire à coins coupés, c'est-à-dire dont la paroi latérale 2 présente huit panneaux 3, et la ceinture de renfort interne 10 huit volets 11. Dans ce cas, le panneau 14 présente, de même, une forme rectangulaire à coins coupés.In FIGS. 7 and 8, two blanks have been shown for making a box of the type shown in FIG. 4, but having a rectangular section with cut corners, that is to say of which the
La figure 9 montre un troisième exemple de réalisation d'une boîte 1 conforme à l'invention, comportant, comme précédemment, une paroi latérale 2 constituée de panneaux 3, des premiers volets 6 formant, partiellement, le fond de la boîte 1 et des seconds volets 7 formant le dessus de celle-ci. Toutefois, dans ce cas, le renfort interne 10 comporte un volet central 15, formant panneau de fond pour ladite boîte 1, relié, sur au moins deux côtés opposés de celui-ci, à un volet latéral 16, 17 par une ligne de pliage 18, lesdits volets latéraux étant, chacun, solidarisés, sur toute leur surface, à un panneau correspondant 3 de ladite paroi latérale 2.Figure 9 shows a third embodiment of a
Plus particulièrement, ledit renfort interne 10 présente, en coupe transversale, une forme de U, et est constitué par trois volets dont le volet central 15 forme, au moins partiellement, le fond de ladite boîte 1 et dont les deux volets latéraux 16, 17 sont solidarisés aux faces internes de panneaux opposés correspondants 3 de ladite paroi latérale 2, notamment par collage. Le volet central 15 peut être solidarisé, notamment par collage, à la face interne des volets de fond 6 ne pouvant constituer qu'une partie du fond de la boîte 1, comme dans l'exemple précédent.More particularly, said
La figure 10 montre le flan 1, et le renfort en U constitué du panneau de fond ou volet central 15 et des deux volets latéraux 16, 17, à partir desquels peut être réalisée, par pliage, la boîte 1 montrée sur la figure 9. La figure 11 montre le même flan 1 que celui de la figure 6, pouvant être utilisé pour réaliser la boîte 1 conforme à ce troisième exemple de réalisation.FIG. 10 shows the blank 1, and the U-shaped reinforcement consisting of the bottom panel or
Les figures 12 et 13, de même que les figures 3, 7 et 8, illustrent des flans 1, et des renforts en U 15, 16, 17, pour la réalisation d'une boîte 1 du type montré sur la figure 9, mais à section rectangulaire à coins coupés. On notera que les volets latéraux 16, 17 peuvent présenter des rabats longitudinaux 19, par exemple rectangulaire, renforçant la solidarisation aux faces internes de la paroi latérale 2 de la boîte 1.Figures 12 and 13, as well as Figures 3, 7 and 8, illustrate
Comme indiqué précédemment, la boîte selon l'invention est réalisée par exemple en utilisant les machines décrites dans les brevets FR-2.629.012 et FR-2.665.137, particulièrement adaptées, après modification à la portée de l'homme du métier, à la mise en place et à la solidarisation de la ceinture de renfort interne et du renfort en U.As indicated above, the box according to the invention is produced for example using the machines described in patents FR-2,629,012 and FR-2,665,137, which are particularly suitable, after modification within the reach of the skilled person, to the establishment and securing of the internal reinforcement belt and the U-shaped reinforcement.
De telles machines permettent, en effet, de solidariser efficacement sur une partie seulement ou sur toute sa surface, le renfort interne, aux panneaux correspondants de la paroi latérale de la boîte.Such machines make it possible, in fact, to efficiently secure the internal reinforcement, on only a part or over its entire surface, to the corresponding panels of the side wall of the box.
La figure 14 montre comme la figure 1 une boîte 1 réalisée avec le procédé selon l'invention.Figure 14 shows like Figure 1 a
La boîte 1 est réalisée en une matière en feuille de carton ondulé double face ou analogue. Elle comporte une paroi latérale 2 constituée d'une pluralité de panneaux 3 (quatre dans cet exemple) reliés par des lignes de pliage 4, ainsi que d'un rabat 5 permettant la solidarisation des "premier" et "dernier" panneaux 3 de la ceinture latérale 2 (figures 2 à 5). Par ailleurs, la boîte 1 présente des premiers volets 6 formant, partiellement, le fond de la boîte 1 et des seconds volets 6 et 7 formant le dessus de celle-ci, les premiers et seconds volets 6 et 7 étant reliés à la ceinture latérale 2 par les lignes de pliage respectives 8 et 9.
Comme on le voit clairement sur la figure 14, le fond de la boîte 1 est constitué, intérieurement à celle-ci, par un panneau 20 en une seule pièce solidarisé à la boîte 1. Dans ce mode de réalisation, la face externe du panneau 10, de forme rectangulaire, est solidarisée par collage aux premiers volets 6. Comme déjà indiqué, on obtient ainsi, intérieurement à la boîte 1, un fond lisse permettant d'éviter le marquage éventuel des produits qui y sont contenus.As can be clearly seen in FIG. 14, the bottom of the
On va maintenant décrire plus précisément le procédé selon l'invention appliqué à la boîte de la figure 14.We will now describe more precisely the method according to the invention applied to the box of FIG. 14.
Après dimensionnement précis du fond et du flan destiné à former la boîte, on commence par plaquer le fond sur un mandrin de même dimension, en ajustant automatiquement la position du fond sur ce dernier par guidage.After precise dimensioning of the bottom and the blank intended to form the box, we start by pressing the bottom on a mandrel of the same dimension, by automatically adjusting the position of the bottom on the latter by guiding.
Puis on enroule le flan autour du mandrin, le fond ou les rabats inférieurs de la paroi latérale ayant été encollés, et on rabat lesdits rabats, une boîte parfaitement équerrée étant ainsi obtenue.Then wrap the blank around the mandrel, the bottom or the bottom flaps of the side wall having been glued, and said flaps are folded down, a perfectly square box being thus obtained.
