The invention is characterised in that the method consists in cutting out said flaps (10-13) all around the side panels (2-5) along a median line (17) between the bonding zone (16) of said flaps on said panels (2-5) and their linking zone with the central panel (9) so as to separate the cover 88) from the can-band carton(1) without cutting out the latter. The invention is applicable to drum-like boxes equipped with heat-shrinkable film (18).

Description

BOITE EN CARTON A OUVERTURE FACILE AVEC RUBAN D'ARRACHEMENT EASY OPENING CARDBOARD BOX WITH TAPPING TAPE
La présente invention concerne un système de déchirage rapide du fond et/ou du couvercle d'une caisse en carton ou matériau analogue, du type "tambour", c'est-à- dire comportant une ceinture prismatique et au moins une coiffe fixée à la ceinture de manière à former le fond et/ou le couvercle de la caisse.The present invention relates to a system for rapid tearing of the bottom and / or the lid of a cardboard box or similar material, of the "drum" type, that is to say comprising a prismatic belt and at least one cap fixed to the belt so as to form the bottom and / or the cover of the box.
Parmi les caisses tambour utilisées actuellement pour le conditionnement, l'expédition et le cas échéant, la présentation d'objets divers, certaines d'entre elles sont en outre équipées d'un film thermorétractable qui est fixé à la caisse de toutes manières pour pouvoir s'étendre librement à l'intérieur de la caisse pour recouvrir des articles logés dans la caisse. Après chauffage, le film se rétracte sur les articles conditionnés et il assure leur maintien ferme sur le fond de la caisse, pendant leur transport .Among the drum boxes currently used for packaging, shipping and if necessary, the presentation of various objects, some of them are also equipped with a heat-shrinkable film which is fixed to the box in any way to be able extend freely inside the box to cover items housed in the box. After heating, the film shrinks on the conditioned articles and ensures their firm hold on the bottom of the box, during their transport.
Ces caisses tambour à film interne thermorétractable, si elles sont particulièrement adaptées au conditionnement et au calage d'objets divers tels que boîtes, flacons, médicaments, documents divers, pris en groupe ou disposés unitairement dans un même emballage, ne présentent pas moins certains inconvénients.These drum boxes with heat-shrinkable internal film, if they are particularly suitable for the packaging and wedging of various objects such as boxes, bottles, medicaments, various documents, taken in a group or arranged individually in the same packaging, do not have less drawbacks. .
En premier lieu, après l'ouverture de la caisse au lieu de destination des articles expédiés, le film plastique rétracté sur les articles conditionnés doit être déchiré pour pouvoir libérer ces articles. Généralement, cette opération de libération des articles est réalisée au moyen d'un outil de coupe, et l'opération de coupe qui est pratiquée est non seulement peu commode mais encore dangereuse pour les articles conditionnés. Notamment, lorsqu'il s'agit d'articles relativement fragiles, tels que livres, documents en papier, boîtes en carton compact imprimées, il arrive très souvent que ces objets soient rayés par suite de l'action de l'outil de coupe allant au- delà du film et pénétrant dans les articles. Un autre inconvénient de ces caisses tambour est que le carton constituant la ceinture et la coiffe d'une part, et la feuille plastique constituant le film thermorétractable d'autre part, ne peuvent pas être séparés commodément l'un de l'autre lorsqu'ils doivent être récupérés dans des containers différents en vue de leur recyclage .Firstly, after opening the box at the place of destination of the items shipped, the plastic film shrunk on the conditioned items must be torn in order to release these items. Generally, this article release operation is carried out by means of a cutting tool, and the cutting operation which is practiced is not only inconvenient but also dangerous for the conditioned articles. In particular, when it comes to relatively fragile articles, such as books, paper documents, printed compact cardboard boxes, it very often happens that these objects are scratched as a result of the action of the cutting tool going beyond the film and entering articles. Another disadvantage of these drum boxes is that the cardboard constituting the belt and the cover on the one hand, and the plastic sheet constituting the heat-shrinkable film on the other hand, cannot be separated conveniently from one another when they must be collected in different containers for recycling.
La présente invention vise à remédier aux inconvénients précités grâce à une caisse tambour, équipée ou non d'un film interne thermorétractable, qui est pourvue d'un système d'ouverture d'un emploi très commode n'exigeant pas de faire appel à un outil de coupe extérieur et permettant de séparer aisément et donc de récupérer dans les meilleures conditions les éléments constitutifs principaux de la caisse tambour, c'est-à-dire le carton d'un côté, le film plastique éventuel de l'autre.The present invention aims to remedy the aforementioned drawbacks by means of a drum box, whether or not equipped with an internal heat-shrinkable film, which is provided with a very convenient job opening system which does not require the use of a external cutting tool and allowing easy separation and therefore recovery in the best conditions of the main constituent elements of the drum box, that is to say the cardboard on one side, the possible plastic film on the other.
A cet égard et conformément à l'un des premiers buts de l'invention, il est proposé une caisse en carton ou analogue, du type caisse tambour comportant naturellement une ceinture prismatique constituée de panneaux latéraux verticaux attenant les uns aux autres, et au moins une coiffe de fond comportant un panneau central de même forme que la section horizontale polygonale de la ceinture et qui est prolongé, le long de ses côtés, par des rabats, repliés perpendiculairement vers le haut et collés par leurs bords externes aux parties inférieures des surfaces externes des panneaux constituant la ceinture, est caractérisée en ce qu'elle comprend un élément d'ouverture allongé, de petite section transversale, tel qu'un fil ou un ruban, apposé, d'une manière aisément détachable, sur les parties inférieures des surfaces externes des panneaux de la ceinture en faisant tout le tour de cette ceinture parallèlement aux chants inférieurs de ces panneaux et chacun des rabats de la coiffe présente une zone linéaire de moindre résistance qui, une fois les rabats collés sur les panneaux de la ceinture, se trouve être située au niveau de l'élément d'ouverture de telle façon qu'en exerçant une traction sur une partie extrême accessible de l'élément d'ouverture et en détachant cet élément des panneaux successifs de la ceinture, tout autour de celle- ci, on provoque une rupture successive des zones linéaires de moindre résistance des rabats entraînant une séparation totale de la coiffe et de la ceinture.In this regard and in accordance with one of the first objects of the invention, a cardboard box or the like is proposed, of the drum box type naturally comprising a prismatic belt made up of vertical side panels adjoining each other, and at least a bottom cover comprising a central panel of the same shape as the horizontal polygonal section of the belt and which is extended, along its sides, by flaps, folded perpendicularly upwards and glued by their external edges to the lower parts of the surfaces external of the panels constituting the belt, is characterized in that it comprises an elongated opening element, of small cross section, such as a wire or a ribbon, affixed, in an easily detachable manner, on the lower parts of the outer surfaces of the belt panels around the entire belt parallel to the lower edges of these panels and each of the flaps of the cap has a linear zone of least resistance which, once the flaps are glued to the panels of the belt, is located at the level of the opening element in such a way that by exerting a traction on an extreme part accessible from the opening element and by detaching this element from the successive panels of the belt, all around the latter, a successive rupture of the linear zones of least resistance of the flaps is caused, causing total separation of the cap and the belt.
Antérieurement à 1 ' invention on connaissait le brevet américain US-3.850.363 qui décrivait un carton dont la ceinture est aisément détachable du fond pour servir de présentoir lorsque la caisse est à destination. Pour cela il était déjà prévu de disposer intérieurement aux parois latérales de la ceinture un ruban périmétrique dont l'arrachement par l'extérieur du carton permettait le détachement de ladite ceinture de son fond sur lequel pouvaient apparaître les produits à présenter. Selon ce document, il était donc préconiser de fendre la ceinture du carton à une hauteur pré-déterminée en vue de son extraction ; au contraire dans l'invention, ce sont les rabats du fond du couvercle que l'on fend, laissant ainsi totalement intacte la ceinture du carton ; à cet effet d'ailleurs, le cordon d'arrachage est disposé sur les faces externes de la ceinture, de manière à venir collaborer avec les rabats de la coiffe ou du fond de la caisse en vue de leur détachement ultérieur.Prior to the invention, US patent US Pat. No. 3,850,363 was known, which described a carton whose belt is easily detachable from the bottom to serve as a display when the case is at its destination. For this it was already planned to have internally to the side walls of the belt a perimeter tape whose tearing from the outside of the cardboard allowed the detachment of said belt from its bottom on which could appear the products to be presented. According to this document, it was therefore recommended to split the belt of the cardboard at a predetermined height for its extraction; on the contrary in the invention, it is the flaps at the bottom of the cover that are split, thus leaving the belt of the carton completely intact; for this purpose, moreover, the tear-off cord is arranged on the external faces of the belt, so as to come to collaborate with the flaps of the cap or of the bottom of the box for their subsequent detachment.
On comprend bien l'avantage considérable de séparer la ceinture d'une caisse tambour de sa coiffe de fond supportant en principe les objets transportés sans toucher à l'intégrité de cette même ceinture. En effet, il est au moins une application particulièrement avantageuse de la caisse selon l'invention consistant à disposer à 1 ' intérieur un film rétractable permettant de fixer des lots d'objets dans une même caisse ainsi équipée en s 'exonérant pour une large part, du nombre et de la forme d'objets à encaisser.It is easy to understand the considerable advantage of separating the belt of a drum box from its bottom cover in principle supporting the objects transported without affecting the integrity of this same belt. In fact, there is at least one particularly advantageous application of the box according to the invention consisting in having inside a retractable film making it possible to fix batches of objects in the same box thus equipped, being largely exempt. , the number and the form of objects to collect.
C'est d'ailleurs un deuxième but poursuivi par l'invention que de procurer un procédé pour le détachement de la coiffe de fond et/ou de fermeture, de la ceinture d'une caisse tambour en carton ou en matériau analogue, ladite ceinture étant prismatique et constituée de panneaux latéraux verticaux attenant les uns aux autres, ladite coiffe comportant un panneau central de même forme et de mêmes dimensions que la section horizontale polygonale de la ceinture et étant prolongé le long de ses côtés par des rabats repliés perpendiculairement vers le haut et collés par leurs bords extrêmes sur les parties inférieures des surfaces externes des panneaux constituant la ceinture, ladite caisse tambour étant munie d'au moins un film plastique thermorétractable attenant à l'un au moins de ses panneaux latéraux, thermoretracte pour bloquer des objets déposés sur la coiffe de fond de la caisse tambour, procédé qui est caractérisé en ce que l'on découpe lesdits rabats tout autour des panneaux latéraux suivant une ligne moyenne comprise entre la zone de collage desdits rabats sur lesdits panneaux et les lignes de leur raccordement au panneau central de manière à séparer la coiffe de la ceinture sans découpage de celle-ci, et sans couper ou détacher préalablement ledit film de la ceinture de la caisse tambour. Selon ce procédé, il est donc possible d'ouvrir une caisse tambour munie d'un film thermoretracte bloquant des objets divers posés sur la coiffe de fond, sans avoir à découper ledit film rétracté au moyen d'objets contondants susceptibles d'altérer voire de détériorer les produits ainsi déballés ; pour cela il est clair qu'il convient d'utiliser des caisses tambour munies de films qui soient uniquement attenants aux panneau de la ceinture : dans ces conditions, puisque la ceinture peut, selon l'invention, être détachée de la coiffe de fond, dans son intégralité et sans altération, on amène simultanément le film rétracté recouvrant les objets, qu'il est donc possible de récupérer ou encore d'exposer à la vente en les laissant dans la coiffe de fond servant alors de barquette de présentation.It is, moreover, a second object pursued by the invention to provide a method for detaching the bottom and / or closure cap, from the belt of a drum case made of cardboard or similar material, said belt. being prismatic and made up of panels vertical lateral panels adjoining each other, said cap comprising a central panel of the same shape and dimensions as the horizontal polygonal section of the belt and being extended along its sides by flaps folded perpendicularly upwards and glued by their edges extremes on the lower parts of the outer surfaces of the panels constituting the belt, said drum body being provided with at least one heat-shrinkable plastic film attached to at least one of its side panels, heat-shrinkable for blocking objects deposited on the bottom cover of the drum body, a method which is characterized in that said flaps are cut all around the side panels along a medium line between the bonding area of said flaps on said panels and the lines of their connection to the central panel so as to separate the cover from the belt without cutting it, and without cutting or detaching r said film of the drum body belt beforehand. According to this method, it is therefore possible to open a drum box provided with a heat-shrinkable film blocking various objects placed on the bottom cover, without having to cut said shrunk film by means of blunt objects capable of altering or even deteriorate the products thus unpacked; for this it is clear that it is advisable to use drum boxes provided with films which are only adjacent to the belt panel: under these conditions, since the belt can, according to the invention, be detached from the bottom cover, in its entirety and without alteration, the retracted film covering the objects is brought in simultaneously, which it is therefore possible to recover or even exhibit for sale by leaving them in the bottom cover then serving as a presentation tray.
On décrira ci-après à titre d'exemple non limitatif, une forme d'exécution de l'invention en référence au dessin annexé sur lequel :An embodiment of the invention will be described below by way of non-limiting example, with reference to the attached drawing in which:
- la figure 1 est une vue en perspective d'une caisse tambour suivant l'invention, respectivement avant et après la séparation de sa ceinture et de sa coiffe inférieure,- Figure 1 is a perspective view of a drum box according to the invention, respectively before and after the separation of his belt and his lower cap,
- la figure 2 est une vue en coupe verticale, à plus grande échelle, faite suivant la ligne II-II de la figure 1, - la figure 3 est une vue en coupe verticale semblable à celle de la figure 2, après séparation de la coiffe inférieure à partir de la ceinture de la caisse,- Figure 2 is a vertical sectional view, on a larger scale, taken along line II-II of Figure 1, - Figure 3 is a vertical sectional view similar to that of Figure 2, after separation of the lower cover from the body belt,
- la figure 4 est une vue en coupe horizontale faite suivant la ligne IV- IV de la figure 2, - la figure 5 est une vue en perspective partielle de la caisse tambour représentée sur les figures 1 à 4,FIG. 4 is a view in horizontal section taken along the line IV - IV of FIG. 2, - FIG. 5 is a partial perspective view of the drum box shown in FIGS. 1 to 4,
- la figure 6 est une vue en plan d'un flanc ou d'une découpe de carton destinée à constituer une coiffe de la caisse tambour, - la figure 7 est une vue en plan d'un flanc ou d'une découpe préparée pour constituer la ceinture d'une caisse tambour suivant l'invention.- Figure 6 is a plan view of a flank or a cutout of cardboard intended to constitute a cover of the drum box, - Figure 7 is a plan view of a flank or of a cutout prepared for constitute the belt of a drum case according to the invention.
La caisse tambour suivant l'invention qui est représentée montée dans la partie gauche de la figure 1, comprend une ceinture prismatique 1 de section horizontale polygonale, par exemple rectangulaire comme il est représenté sur le dessin. Cette ceinture 1, réalisée par exemple en carton ondulé rigide, comprend une succession de panneaux attenants les uns aux autres et alignés pour former une découpe telle que représentée à plat sur la figure 7. Dans le cas d'une caisse rectangulaire la ceinture 1 comprend donc successivement un grand panneau 2, un petit panneau 3, un autre grand panneau 4, un autre petit panneau 5 et pour terminer la découpe, une patte de fixation 6, tous ces panneaux et la patte étant séparés par des lignes de pliage transversales 7. Ces lignes de pliage 7 forment les arêtes du prisme que constitue la ceinture 1, une fois celle-ci fermée sur elle-même au moyen de la patte de fixation 6 collée à l'intérieur du grand panneau opposé 2.The drum body according to the invention which is shown mounted in the left part of FIG. 1, comprises a prismatic belt 1 of polygonal horizontal section, for example rectangular as shown in the drawing. This belt 1, made for example of rigid corrugated cardboard, comprises a succession of panels adjoining each other and aligned to form a cutout as shown flat in FIG. 7. In the case of a rectangular box, the belt 1 comprises so successively a large panel 2, a small panel 3, another large panel 4, another small panel 5 and to complete the cutting, a fixing tab 6, all these panels and the tab being separated by transverse fold lines 7 These fold lines 7 form the edges of the prism formed by the belt 1, once the latter is closed on itself by means of the fixing tab 6 glued inside the large opposite panel 2.
La caisse tambour comporte également au moins une coiffe 8 qui est fixée à la ceinture 1 comme il est représenté dans la partie gauche de la figure 1. Sur cette figure, la caisse ne comporte qu'une coiffe inférieure 8, constituant le fond de la caisse, mais il est bien évident qu'une coiffe similaire pourrait être fixée à la partie supérieure de la ceinture 1, pour fermer totalement la caisse.The drum body also comprises at least one cover 8 which is fixed to the belt 1 as shown in the left part of FIG. 1. On this Figure, the box has only a lower cover 8, constituting the bottom of the box, but it is obvious that a similar cover could be attached to the upper part of the belt 1, to completely close the box.
La coiffe 8 est formée à partir d'un flanc ou d'une découpe de carton qui peut être un carton plus léger et de moindre qualité que le carton constituant la ceinture 1. La découpe destinée à former la coiffe 8, présente un panneau central 9 de même forme et de mêmes dimensions que celles de la section horizontale de la ceinture 1, c'est-à-dire de forme rectangulaire dans l'exemple particulier décrit. Ce panneau central 9 est prolongée vers 1 ' extérieur par des rabats s ' étendant à partir de ses quatre côtés, à savoir successivement un grand rabat 10, un petit rabat 11, un autre grand rabat 12 et un autre petit rabat 13. Ces rabats 10-13 sont reliés au panneau central rectangulaire 9 par l'intermédiaire de lignes de pliage 14 de manière que ces rabats 10 puissent être repliés verticalement vers le haut, c'est-à-dire perpendiculairement au plan du panneau central 9, en vue de leur fixation par collage sur les parties inférieures des panneaux respectifs 2-5 de la ceinture 1.The cover 8 is formed from a flank or a cutout of cardboard which can be a lighter and lower quality cardboard than the cardboard constituting the belt 1. The cutout intended to form the cover 8, has a central panel 9 of the same shape and the same dimensions as those of the horizontal section of the belt 1, that is to say of rectangular shape in the particular example described. This central panel 9 is extended towards the outside by flaps extending from its four sides, namely successively a large flap 10, a small flap 11, another large flap 12 and another small flap 13. These flaps 10-13 are connected to the rectangular central panel 9 by means of fold lines 14 so that these flaps 10 can be folded vertically upwards, that is to say perpendicular to the plane of the central panel 9, in view of their fixing by gluing on the lower parts of the respective panels 2-5 of the belt 1.
Suivant l'invention, la caisse tambour est pourvue d'un élément d'ouverture 15 allongé, de petite section transversale, tel qu'un fil ou un ruban, qui est apposé d'une manière aisément détachable sur les parties inférieures des surfaces externes des quatre panneaux 2-5 de la ceinture 1, en faisant tout le tour de cette ceinture, parallèlement aux chants inférieurs de ses panneaux 2-5. L'élément d'ouverture 15 est situé à l'extrémité inférieure de la zone 16 où a lieu le collage des parties extrêmes supérieures des rabats 10-13 de la coiffe 8 sur les panneaux 2-5 de la ceinture 1, comme on peut mieux le voir sur les figures 2 et 3.According to the invention, the drum body is provided with an elongated opening element 15, of small cross section, such as a wire or a ribbon, which is affixed in an easily detachable manner on the lower parts of the external surfaces. of the four panels 2-5 of the belt 1, going all around this belt, parallel to the lower edges of its panels 2-5. The opening element 15 is located at the lower end of the zone 16 where the upper end parts of the flaps 10-13 of the cover 8 take place on the panels 2-5 of the belt 1, as can be see it better in Figures 2 and 3.
L'un des rabats, en l'occurrence le grand rabat 12, présente, à l'une de ses extrémités, un évidemment 12a, pour permettre la sortie à l'extérieur d'une partie extrême 15a de l'élément d'ouverture 15.One of the flaps, in this case the large flap 12, has, at one of its ends, a recess 12a, to allow the exit outside of a part end 15a of the opening element 15.
Par ailleurs, chacun des rabats 10-13 de la coiffe 8 présente une zone linéaire de moindre résistance 17 horizontale, c'est-à-dire s ' étendant parallèlement à la ligne de pliage 14 entre le rabat et le panneau central 9 de la coiffe 8. La distance entre la zone de moindre résistance 17 et la ligne de pliage correspondante 14 correspond sensiblement à la distance entre l'élément d'ouverture 15 et le chant inférieur de chacun des panneaux 2-5 de la ceinture 1.Furthermore, each of the flaps 10-13 of the cover 8 has a linear zone of least resistance 17 horizontal, that is to say extending parallel to the fold line 14 between the flap and the central panel 9 of the cap 8. The distance between the zone of least resistance 17 and the corresponding fold line 14 corresponds substantially to the distance between the opening element 15 and the lower edge of each of the panels 2-5 of the belt 1.
Ainsi qu'il est représenté sur les figures 2 et 3 , la caisse tambour peut être équipée, dans son volume interne, d'au moins un film en matière plastique thermorétractable 18 qui sert, une fois rétracté, à maintenir fermement des objets conditionnés 19 disposés sur le panneau central ou le fond 9 de la coiffe 8.As shown in FIGS. 2 and 3, the drum box can be equipped, in its internal volume, with at least one film of heat-shrinkable plastic material 18 which, once retracted, for firmly holding packaged objects 19 arranged on the central panel or the bottom 9 of the cover 8.
Parmi les nombreuses caisses connues dans l'art antérieur et équipées de film thermorétractable, on connaît les caisses munies de films qui sont attachés au fond des caisses ou sur les rabats de fond par exemple ; d'autres catégories d'emballages comportant des films rétractables ont adopté le principe d'une fixation des films thermorétractables sur les panneaux verticaux des caisses ainsi équipées, c'est-à-dire sur les parties internes des ceintures lorsqu'il s'agit de caisses tambour ; dans cette dernière catégorie, deux variantes sont encore connues : dans la première, les films plastiques sont directement collés sur les parois internes, et selon une autre variante plus élaborée, les films plastiques peuvent être collés sur la ou les faces externes de la ceinture et repliés vers l'intérieur de la caisse en bénéficiant du coincement de la ceinture à 1 ' intérieur de la coiffe de fond par exemple pour renforcer leur résistance à l'arrachement lors des transports notamment. Dans la description qui va suivre, il sera fait exclusivement référence à ces deux dernières variantes.Among the numerous boxes known in the prior art and equipped with heat-shrinkable film, boxes are known provided with films which are attached to the bottom of the boxes or on the bottom flaps for example; other categories of packaging comprising shrink films have adopted the principle of fixing heat-shrinkable films on the vertical panels of the boxes thus equipped, that is to say on the internal parts of the belts when it comes to drum boxes; in this latter category, two variants are still known: in the first, the plastic films are directly bonded to the internal walls, and according to another more elaborate variant, the plastic films can be bonded to the external face or faces of the belt and folded towards the inside of the body while benefiting from the jamming of the belt inside the bottom cover for example to reinforce their resistance to tearing during transport in particular. In the description which follows, reference will be made exclusively to these last two variants.
Lorsque l'on désire libérer les objets 19 conditionnés dans la caisse tambour ainsi équipée de film thermorétractable 18 solidarisé sur les panneaux 2-5 de la ceinture 1, il suffit de tirer sur la partie extrême 15a de l'élément d'ouverture 15, vers l'extérieur, dans le sens des flèches F sur les figures 1 et 2. Cette traction entraîne le détachement de la partie initiale de l'élément d'ouverture 15 du grand panneau 4 auquel il est attaché, et ensuite l'arrachement de la zone de moindre résistance 17 du rabat 12 adjacent. Ce détachement et cet arrachement se poursuivent successivement sur les panneaux 5, 2 et 3 et sur les rabats 13,10,11. Seules les parties supérieures, c'est-à-dire celles situées au-dessus des zones de moindre résistance 17, des rabats 10-13 demeurent attachées aux panneaux de la ceinture 1. La coiffe 8 portant les objets 19 précédemment conditionnés peut alors être utilisée comme présentoir de ces objets, comme il est représenté dans la partie droite de la figure 1.When it is desired to release the objects 19 packaged in the drum box thus equipped with film heat-shrinkable 18 secured to the panels 2-5 of the belt 1, it suffices to pull on the end part 15a of the opening element 15, towards the outside, in the direction of the arrows F in FIGS. 1 and 2. This traction results in the detachment of the initial part of the opening element 15 from the large panel 4 to which it is attached, and then the tearing of the zone of least resistance 17 from the adjacent flap 12. This detachment and this tearing continues successively on the panels 5, 2 and 3 and on the flaps 13, 10, 11. Only the upper parts, that is to say those situated above the zones of least resistance 17, flaps 10-13 remain attached to the panels of the belt 1. The cap 8 carrying the previously conditioned objects 19 can then be used as a display of these objects, as shown in the right part of Figure 1.
On voit donc, d'après ce qui précède, que les objets 19 précédemment conditionnés ne peuvent subir aucun dommage au cours de l'opération d'ouverture de la caisse puisqu'on ne fait pas appel pour cette opération à un quelconque outil de coupe. Par ailleurs, il est très facile de récupérer le film plastique thermoretracte 18 qui reste solidaire de la ceinture 1 puisqu'il est aisément accessible du dessous et peut donc être séparé sans difficulté en vue d'un recyclage éventuel.It is therefore seen, from the above, that the previously conditioned objects 19 can not suffer any damage during the operation of opening the box since no cutting tool is used for this operation. . Furthermore, it is very easy to recover the heat-shrinkable plastic film 18 which remains integral with the belt 1 since it is easily accessible from below and can therefore be separated without difficulty with a view to possible recycling.
En référence à la figure 7 montrant en vue de dessus une découpe à plat préparée pour constituer la ceinture 1 d'une caisse tambour et selon une dernière caractéristique avantageuse de l'invention, l'élément d'ouverture 15 pouvant être, comme on l'a vu, un fil ou un ruban, s'étendre le long du bord longitudinal de la découpe à plat de la ceinture en adhérant un minimum, aux quatre panneaux 2-5 constituant ladite ceinture, et le cas échéant à la patte de fixation 6 ; la mise en place de cet élément d'ouverture 15 peut donc être aisément opéré, par exemple en apposant quelques points de colle sur la découpe tout le long du bord longitudinal correspondant à la partie inférieure de la caisse montée ; cette opération peut être facilement effectuée en continu, soit au moment de la fabrication des découpes à plat, soit le cas échéant, juste avant l'introduction de la découpe sur un mandrin de formation au moment du montage de la caisse tambour. Referring to Figure 7 showing a top view of a flat cutout prepared to form the belt 1 of a drum case and according to a last advantageous characteristic of the invention, the opening element 15 may be, as shown 'saw, a wire or a ribbon, extend along the longitudinal edge of the flat cut of the belt while adhering a minimum, to the four panels 2-5 constituting said belt, and if necessary to the fixing lug 6; the establishment of this opening element 15 can therefore be easily operated, for example by affixing a few dots of glue on the cutout along the longitudinal edge corresponding to the lower part of the mounted box; this operation can be easily carried out continuously, either at the time of the manufacture of the flat blanks, or if necessary, just before the introduction of the blank on a training mandrel at the time of assembly of the drum box.
