Abstract

The small box is made from a rectangular sheet of flexible material which is sub-divided into five panels (1 to 5) by four parallel fold lines (7,8,9,10). The sheet is folded so that the panels (1) and (3) form side walls, the panel (2) forms a base, the panel (4) forms a lid and the panel (5) forms a lid securing flap. End walls (12) are made of plastics and have U-shaped grooves on one face to fit the end edges of the side walls and base. An additional groove (17) is formed near the edge of each end wall to receive the edges of the securing flap.

Description

La présente invention a pour objet un procédé pour La fabrication de boites à coffret. ELLe concerne aussi Les boîtes à coffret qui résultent dudit procédé, ainsi que des éléments caractéristiques à utiliser pour La formation de ces boites.The present invention relates to a method for the manufacture of box boxes. It also relates to the box boxes which result from said process, as well as characteristic elements to be used for the formation of these boxes.

La fabrication de boites de qualité supérieure résulte coûteuse en raison de La nécessité d'effectuer sur Les flans des encollages, dont L' exécution complique Les appareiLLages et aLLonge Les temps de travail. En outre, L'opportunité d'acheminer Les boites au Lieu d'utilisation en une forme aplatie pour en réduire L'encombrement oblige à adopter des formes spécifiques, qui pas toujours correspondent aux qualités désirées pour La boite, et comporte sur Le Lieu d'utilisation des opérations manuelles ou des appareillages très complexes pour Le déploiement des boîtes. En particulier il n'est pas possible, avec ces techniques, de réaLiser d'une façon satisfaisante des boîtes à coffret, c'est-à-dire pourvues d'un couvercle souLevabLe et abaissable constituant l'une des faces Les plus grandes de La boîte. En outre, avec Les techniques connues L' on a des difficultés pour réaliser des moyens efficaces de retenue en position fermée du couvercle, qui puissent facilement être neutralisés pour L'ouverture de La boite, ou/et des moyens de retenue en fermeture ayant Le caractère de scellés, c'est-à-dire ouvrant seulement par arrachement.The manufacture of boxes of superior quality is costly due to the need to carry out gluing on the blanks, the execution of which complicates the equipment and lengthens the working times. In addition, the opportunity to send the boxes to the place of use in a flattened form to reduce the size requires specific forms, which do not always correspond to the desired qualities for the box, and includes on the place of use of manual operations or very complex equipment for the deployment of boxes. In particular, it is not possible, with these techniques, to satisfactorily produce box boxes, that is to say provided with a liftable and lowerable cover constituting one of the largest faces of The box. In addition, with known techniques, it is difficult to produce effective means of retaining the closed position of the lid, which can easily be neutralized for opening the box, or / and closing retaining means having the character of seals, that is to say opening only by tearing off.

• Le but de La présente invention est de réaliser un procédé pour La fabrication de boîtes à coffret, qui permette de rationaliser de La meilleure façon Les opérations de fabrication et d'utilisation industrielle de La boite, qui en outre rende possible, dans Les cas où cela est désiré, L'éLimination totale des opérations d'encollage, ainsi que La réalisation de moyen de retenue en fermeture ouvrant ou/et ayant Le caractère de scellés.• The purpose of the present invention is to provide a process for the manufacture of boxed boxes, which makes it possible to rationalize in the best way the operations of manufacture and industrial use of the box, which in addition makes it possible, in the cases where desired, the total elimination of the sizing operations, as well as the realization of retaining means in closing opening or / and having the character of seals.

Ce but est atteint, selon l'invention, par un procédé qui comprend Les opérations de:

  • - prédisposer un élément découpé formé par un matériel LameLLaire flexible portant au moins quatre rainurages gravés, paralléles entre eux et perpendiculaires à deux côtés opposés de L'éLément découpé, lequel résulte ainsi subdivisé en au moins cinq sections;
  • - prédisposer deux flancs formés en matériel synthétique, chacun desquels présente, creusé dans une face, un premier canal en U ayant des bras dont Les Longueurs correspondent, dans Le même ordre, aux distances de quatre successifs des rainurages susdits, chacun du rainurage précé- dent ou du bord initial de L'éLément découpé, et présente en outre un deuxième canal substantiellement rectiligne, parallèle et adjacent à l' extérieur à L'un des deux bras parallèles du premier canal en U;
  • plier Les sections de l'élément découpé lelong 'des rainurages, ainsi donnant à l'élément découpé La forme générale de La boite à réaliser, ouverte et dépourvue des flancs;
  • - et insérer et fixer Les extrémités d'au moins trois des sections de L'éLément découpé plié dans Les bras correspondants desdits canaux en U des deux flancs;
  • - deux sections de L'éLément découpé restant ainsi Libres des flancs, L'une d'elle formant un couvercle abaissable et soulevable et l' autre, terminale, formant une patte de fermeture que L'on peut insérer dans Ledit deuxième canal des flancs.
This object is achieved, according to the invention, by a method which comprises The operations of:
  • - predispose a cut element formed by a flexible LameLLaire material carrying at least four engraved grooves, parallel to each other and perpendicular to two opposite sides of the cut element, which thus results subdivided into at least five sections;
  • - Predispose two flanks formed of synthetic material, each of which has, hollowed in one face, a first U-shaped channel having arms whose lengths correspond, in the same order, to the distances of four successive grooves aforesaid, each of the grooves previously tooth or the initial edge of the cut element, and further has a second substantially straight channel, parallel and adjacent to the outside of one of the two parallel arms of the first U-shaped channel;
  • folding the sections of the cut element along the grooves, thus giving the cut element the general shape of the box to be made, open and devoid of the sides;
  • - And insert and fix the ends of at least three of the sections of the cut element folded in the corresponding arms of said U-shaped channels of the two sides;
  • - two sections of the cut element thus remaining free from the sides, one of them forming a lowerable and liftable cover and the other, terminal, forming a closing tab which can be inserted in said second flank channel .

Grâce à ces caractéristiques, L'éLément découpé peut être produit facilement et économiquement, iL peut être fourni en forme déployée à l' utilisation et il est facile à plier, manuellement ou par des appareillages simples, grâce au parallélisme des Lignes de pliage définies par Les rainurages; Les flancs peuvent être facilement et économiquement produits dans Les formes désirées par moulage ou par injection de matières plastiques et ils peuvent aussi être fournis à L'utiLisation en des ensembles compacts de petit encombrement; et L'insertion des extrémités des sections de L'éLément découpé plié dans Le canal correspondant des flancs est une opération facile à exécuter et à organiser aussi bien manuellement que par des appareillages automatiques simples et de fonctionnement sûr.Thanks to these characteristics, the cut element can be produced easily and economically, iL can be supplied in a deployed form for use and it is easy to fold, manually or by simple devices, thanks to the parallelism of the folding lines defined by The grooves; The sidewalls can be easily and economically produced in the desired shapes by molding or by injection of plastics and they can also be supplied for use in compact assemblies of small size; and The insertion of the ends of the sections of the cut out element folded in the corresponding channel of the sides is an operation easy to execute and to organize as well my only by simple and safe automatic devices.

La fixation des extrémités des sections dans Le canal en U peut être exécutée, lorsque cela ne représente pas un inconvénient, par encollage, mais plus avantageusement elle peut être exécutée par engagement mécanique irréversible de conformations des bords de l'élément découpé et du canal en U des flancs, ainsi évitant tout encollage. Enfin, des simples conformations opportunes des pattes latérales de La section formant patte de fermeture, et des canaux d'insertion correspondants des flancs, permettent de réaliser des moyens efficaces de retenue en position fermée du couvercle, facilement ouvrant ou/et formant scellés.The fixing of the ends of the sections in the U channel can be carried out, when this does not represent a drawback, by gluing, but more advantageously it can be carried out by irreversible mechanical engagement of conformations of the edges of the cut element and of the channel in U of the sides, thus avoiding any gluing. Finally, simple convenient conformations of the lateral tabs of the section forming the closing tab, and corresponding insertion channels of the sides, make it possible to produce effective means of retaining the closed position of the cover, easily opening or / and forming seals.

Ces caractéristiques et d'autres des objets de L'invention ressortiront plus clairement de La description suivante d'un mode exemplificatif et non Limitatif de réalisation de L'invention, schématiquement représenté dans les dessins annexés, dans LesqueLs:

  • Fig. 1 montre en petite échelle une boite à coffret réalisée en application de L'invention, en condition fermée;
  • Fig. 2 montre La même boîte à coffret de La figure 1, mais en condition ouverte après arrachement des sceLLés;
  • Fig. 3 montre l'un des flancs en échelle plus grande et en vue interrompue de La face destinée à être tournée vers L'intérieur de La boîte;
  • Fig. 4 montre en echelle encore plus grande un détail du deuxième canal d'un flanc, avec indication de La section de La patte de fermeture de l'élément découpé plié, y insérée;

  • Fig. 6 montre La forme des découpages exécutés dans l'élément découpé pour réaliser l'accrochage illustré dans La figure 5.
These characteristics and others of the objects of the invention will emerge more clearly from the following description of an illustrative and nonlimiting embodiment of the invention, schematically represented in the accompanying drawings, in LesqueLs:
  • Fig. 1 shows on a small scale a box box produced in application of the invention, in closed condition;
  • Fig. 2 shows the same box box of FIG. 1, but in open condition after tearing off the sceLLes;
  • Fig. 3 shows one of the sides in a larger scale and in interrupted view of the face intended to be turned towards the interior of the box;

  • Fig. 6 shows the shape of the cuts made in the cut element to achieve the attachment illustrated in FIG. 5.

L'élément découpé destiné à former La boite selon Les figures 1 et 2 a une forme substantiellement rectangulaire et présente principalement cinq sections: 1 formant Le front de La boite; 2 formant Le fond; 3 formant Le dos; 4 formant Le couvercle soulevable et abaissable; et 5 formant une patte de fermeture. Dans La forme représentée, L'éLément découpé présente encore une sixième section 6, d'extension réduite, destinée à former une patte repliée à L'intérieur à L'ouverture de La boite, spécialement pour raidir Le front 1. Lesdites sections, de forme rectangulaire, sont séparées L'une de L'autre par des rainurages, respectivement 7, 8, 9, 10 et 11. L'éLément découpé 1-6 peut être réalisé en n' importe quel matériel LameLLaire quelque peu flexible, comme du carton, du carton couplé avec du Laminé plastique ou/et métallique, de La mince tôle métallique, du matériel plastique Laminé, etc.The cut element intended to form the box according to FIGS. 1 and 2 has a substantially rectangular shape and mainly presents five sections: 1 forming the front of the box; 2 forming the bottom; 3 forming the back; 4 forming The liftable and lowerable cover; and 5 forming a closure tab. In the form shown, the cut element also has a sixth section 6, of reduced extension, intended to form a folded tab inside the opening of the box, especially to stiffen the front 1. Said sections, rectangular shape, are separated from each other by grooves, respectively 7, 8, 9, 10 and 11. The cutout element 1-6 can be made of any somewhat flexible Lamellar material, such as cardboard, cardboard coupled with plastic or / and metallic laminate, thin sheet metal, laminated plastic material, etc.

Chacun des flancs destinés à former La boite en combinaison avec l' élément découpé 1-6 a - en ce cas - une forme substantiellement rectangulaire, lelong de trois côtés de LaqueLLe, celles avant, dessous et arrière, s'étendent Les trois bras 13, 14, 15 d'un canal en U creusé dans La face du fLanc 12 qui est tournée vers L'intérieur de La boite. Dans La forme représentée, Le bras arrière 15 du canal en U est ouvert supérieurement, tandis que Le bras avant 13 se raccorde supérieurement à un court tronçon de canal 16, substantiellement parallèle du bras dessous 14. Les Longueurs respectives de ces bras de canal 13 à 16 correspondent, dans Le même ordre, aux Largeurs des sections 1, 2, 3 et 6 de L'élément découpé 1-6, mesurées entre les rainurages qui Les Limitent ou (pour La section 6) entre Le rainurage 11 et Le bord qui Limite l'élément découpé.Each of the sides intended to form the box in combination with the cutout element 1-6 has - in this case - a substantially rectangular shape, along three sides of the lacquer, those front, bottom and rear, extend the three arms 13 , 14, 15 of a U-shaped channel dug in the face of the side 12 which is turned towards the interior of the box. In the form shown, the rear arm 15 of the U-shaped channel is open at the top, while the front arm 13 is connected at the top to a short section of channel 16, substantially parallel to the arm below 14. The respective lengths of these channel arms 13 to 16 correspond, in the same order, to the widths of sections 1, 2, 3 and 6 of the cut element 1-6, measured between the grooves which limit them or (for section 6) between the grooving 11 and the edge which limits the cut element.

En outre, chaque flanc 12 présente lelong du côté avant, parallèlement et à L'extérieur du bras avant 13 du canal en U, un deuxième canal rectiligne 17, ouvert supérieurement.In addition, each sidewall 12 has along the front side, parallel to and outside the front arm 13 of the U-shaped channel, a second rectilinear channel 17, open at the top.

Au moment et sur Le Lieu du montage de La boite - qui peuvent être différents du moment et du Lieu de fabrication des éléments composants - l'élément découpé 1-6 est plié lelong des rainurages 7-11, en Lui donnant substantiellement La forme qui résulte de La figure 2, et ensuite ses deux bords opposés sont insérés dans Le canal en U 13-16 des flancs 12 et y sont fixés; par cette opération La boite à coffret est assemblée, ouverte et prête pour être remplie avec les articles qu'elle doit contenir. Pour la fermeture de La boite, Le couvercle 4 est abaissé jusqu'au contact avec le côté dessus 18 des flancs 12, en insérant Les côtés de La patte de fermeture 5 dans Le deuxième canal 17 des flancs 12. La boite, ainsi remplie et fermée, peut être scellée de n'importe quelle façon et envoyée aux opérations ultérieures.At the time and at the place of assembly of the box - which may be different from the time and place of manufacture of the component elements - the cut element 1-6 is bent along the grooves 7-11, giving it substantially the shape which follows from Figure 2, and then its two opposite edges are inserted into the U channel 13-16 of the sides 12 and are attached thereto; by this operation The box box is assembled, opened and ready to be filled with the articles which it must contain. To close the box, the cover 4 is lowered until it contacts the top side 18 of the sides 12, by inserting the sides of the closing tab 5 in the second channel 17 of the sides 12. The box, thus filled and closed, can be sealed in any way and sent to subsequent operations.

Pour obtenir une fermeture plus parfaite du couvercle 4, de préférence Le côté dessus 18 des flancs 12 est courbé avec une légère convexité vers L'extérieur, de façon que, à boite fermée, Le couvercle 4 résulte Lui aussi Légèrement courbé.To obtain a more perfect closure of the cover 4, preferably the top side 18 of the sides 12 is curved with a slight convexity towards the outside, so that, with the box closed, the cover 4 is also slightly curved.

Un moyen très avantageux pour La fixation de L'éLément découpé 1-6 par rapport aux flancs 12 est représenté dans Les figures 3, 5 et 6. L' une des parois des bras de 13 à 15 (et éventuellement du bras 16 aussi) du canal en U des flancs 12 présente à des distances régulières des dents 19, tandis que des saillies 20 sortent, à une certaine distance des dents 19, de La paroi opposée du canal. Dans les points des bords de l'élément découpé 1-6, qui correspondent aux dents 19, sont pratiqués des découpages 22 en forme de C, comme il le montre La figure 6; chaque découpage définit une patte 22 élastiquement soulevable. Lorsque Les bords de L'éLément découpé sont insérés dans Le canal en U des flancs, La patte 22 reste légèrement soulevée par La dent 19 correspondante, tandis que Les saillies latérales 20 gardent Le bord 21 du découpage sûrement engagé avec La dent 19, comme montré par la figure 5. Par cette disposition, L'insertion des bords de l'élément découpé dans Les canaux en U des flancs donne Lieu à un engagement mécanique irréversible qui fixe définitivement entre eux les flancs et les parois de La boîte.A very advantageous means for fixing the cut element 1-6 relative to the sides 12 is shown in Figures 3, 5 and 6. One of the walls of the arms from 13 to 15 (and possibly from the arm 16 also) of the U-shaped channel of the sides 12 present at regular distances from the teeth 19, while protrusions 20 come out, at a certain distance from the teeth 19, from the opposite wall of the channel. In the points of the edges of the cut element 1-6, which correspond to the teeth 19, cutouts 22 are made in the form of C, as shown in FIG. 6; each cutout defines an elastically liftable tab 22. When the edges of the cut element are inserted into the U-shaped channel of the sides, the tab 22 remains slightly raised by the corresponding tooth 19, while the lateral projections 20 keep the edge 21 of the cut securely engaged with the tooth 19, as shown in Figure 5. By this arrangement, the insertion of the edges of the cut element in the U-shaped channels of the sides gives rise to an irreversible mechanical engagement which definitively fixes between them the sides and the walls of the box.

De préférence Les saillies latérales 20 ne sont pas prévus seulement aux côtés des dents 19, mais elles sont régulièrement espacées lelong de toute La paroi correspondante du canal en U, et ont une Longueur choisie de sorte que Le bord de l'élément découpé résulte inséré avec un certain forcement entre ces saillies et La paroi opposée du canal en U. De cette façon on obtient une immobilisation réciproque efficace entre Les flancs et L'éLément découpé, LaqueLLe donne une rigidité particulière à La boîte, spécialement dans sa condition ouverte.Preferably, the lateral projections 20 are not provided only at the sides of the teeth 19, but they are regularly spaced along the entire corresponding wall of the U-shaped channel, and have a length chosen so that the edge of the cut element is inserted. with a certain forcing between these projections and the opposite wall of the U-shaped channel. In this way we obtain an effective reciprocal immobilization between the sides and the cut element, which gives a particular rigidity to the box, especially in its open condition.

IL est en outre avantageux que le deuxième canal 17 des flancs 12 présente une dent 23 tournée à L'intérieur, tandis que des découpages correspondants 24 de Longueur Limitée définissent lelong des bords latéraux de La patte de fermeture 5 de La boite des petites pattes 25 qui, au moment de La fermeture de La boîte, vont se disposer sous La dent 23 des canaux 17 des flancs, comme iL Le montre La figure 4, ainsi tenant stablement fermée La boîte. Cependant, iL est suffisant d'exercer de l' extérieur une pression sur Les pattes 25, selon La flèche IV de La figure 4, pour déformer élastiquement Les pattes 25 en Les déplacant en 25' (figure 4), ainsi permettant alors L'ouverture de La boite. De cette façon, Les pattes 25 forment un système permanent de fermeture ouvrant, que l'on peut utiliser indéfiniment dans L'empLoi successif de La boîte.It is further advantageous that the second channel 17 of the sides 12 has a tooth 23 turned inside, while corresponding cutouts 24 of limited length define along the lateral edges of the closing tab 5 of the box of small legs 25 which, at the time of closing the box, will be disposed under the tooth 23 of the channels 17 of the sides, as shown in Figure 4, thus keeping the box stably closed. However, iL is sufficient to exert external pressure on the legs 25, according to arrow IV of Figure 4, to elastically deform the legs 25 by moving them in 25 '(Figure 4), thus allowing L' opening of the box. In this way, the tabs 25 form a permanent opening closure system, which can be used indefinitely in the successive use of the box.

Dans Les cas où L'on désire que La boite puisse être mise en vente en un état scellé, une deuxième dent 26, celle-ci tournée vers l'extérieur, peut être formée dans Le canal 17 sous La dent 23 (si celle-ci a été prévue), tandis qu'une ligne d'arrachement 27 sépare de La patte de fermeture 5 de La boîte des petites pattes arrachables correspondantes 28. CeLLes-ci s'engagent sous La dent 26 du canal 17 et ensuite elles empêchent positivement L'ouverture de La boîte. Pour ouvrir La boite, iL faut appliquer un effort suffisant à arracher Les pattes 28, qui se détachent de La patte de fermeture 5 en permettant L'ouverture de La boîte, LaqueLLe toutefois montre d'avoir été ouverte par Le manque des pattes 28, qui forment donc des scellés de garantie.In cases where it is desired that the box can be put on sale in a sealed state, a second tooth 26, the latter facing outwards, can be formed in the channel 17 under tooth 23 (if this- ci was provided), while a tearing line 27 separates from the closing tab 5 of the box small corresponding tear-off tabs 28. These engage under tooth 26 of the channel 17 and then they positively prevent The opening of the box. To open the box, iL must apply sufficient effort to tear off the tabs 28, which detach from the closing tab 5 allowing the opening of the box, which however shows that it was opened by the lack of tabs 28, which therefore form guarantee seals.

Un manche en matière plastique flexibte 29 peut être appliqué au front 1 de La boite, et il resulte accessible à travers une fente 30 de La patte de fermeture 5, en permettant Le transport de La boite comme une petite valise et en assurant La fermeture de La boite pendant Le transport. Ce moyen de fermeture et de transport peut remplacer Les pattes 25 ou en compléter L'action.A flexible plastic handle 29 can be applied to the front 1 of the box, and it results accessible through a slot 30 of the closing tab 5, allowing the transport of the box like a small suitcase and ensuring the closing of The box during transport. This means of closure and transport can replace the legs 25 or complete the action.

Comme on Le comprend, l'invention n'est pas limitée à l'application à des boites substantiellement parallélépipèdes, comme celle illustrée à titre d'exemple; Les parois principales de la boîte, et donc les côtés des flancs, peuvent être en nombre différent de quatre, et de plus lesdites parois peuvent être aussi courbes, de sorte que La boîte peut prendre n'importe quelle forme prismatique et même partiellement ou totalement cylindrique.As will be understood, the invention is not limited to application to substantially parallelepiped boxes, such as that illustrated by way of example; The main walls of the box, and therefore the sides of the sides, can be in number different from four, and moreover said walls can also be curved, so that the box can take any prismatic shape and even partially or totally cylindrical.

Les conformations coopérant des bords de l'élément découpé et du canal en U, visant à coopérer réciproquement afin de réaliser un engagement irréversible, peuvent être changées par rapport à celles illustrées à titre d'exemple et, comme moyens de fermeture de la boite, peuvent aussi être adoptés des moyens traditionnels, comme des crochets, des boutons à pression, etc., au lieu des dispositions originales décrites.The cooperating conformations of the edges of the cut element and of the U-shaped channel, aiming to cooperate reciprocally in order to achieve an irreversible engagement, can be changed compared to those illustrated by way of example and, as means of closing the box, can also be adopted by traditional means, such as hooks, snaps, etc., instead of the original arrangements described.

En outre, dans Les cas où une opération d'encollage n'est pas considérée comme un inconvénient, ou bien de toute façon si l'on désire faire recours à celle-ci, La fixation des bords de l'élément découpé dans Le canal en U des flancs peut être réalisé par un collant, Le procédé selon l'invention demeurant de toute façon avantageux en vue de La simplification soit de La conformation de l'élément découpé que des opérations de pliage de cet élément lors de l'assemblage de La boîte.In addition, in cases where a gluing operation is not considered a drawback, or in any case if one wishes to use it, fixing the edges of the cut element in the channel U-shaped sidewalls can be produced by a sticker. The method according to the invention remains advantageous in any case with a view to simplification either of the conformation of the cut element than of operations for folding this element during the assembly of The box.
