Abstract

A box made from cardboard or other semi-rigid material has side and end walls and a base made from two inner and two outer (42,82) parallel flaps, joined together by fastenings. The base flaps have diagonal fold lines (43,83) and a system (23,63) for separating the inner base flaps from the outer ones along the fold lines. The base flaps are joined together by areas of adhesive between their facing surfaces. The separating system is made in the form of cuts in the inner and outer flaps which cause them to separate from one another when pushed inwards.

Description

L'invention concerne le domaine des emballages en carton ou autre matériau semi-rigide. Elle vise en particulier un emballage du type comprenant une partie avec quatre panneaux formant une ceinture et au moins une partie constituant une paroi de fond.The invention relates to the field of packaging made of cardboard or other semi-rigid material. It relates in particular to a packaging of the type comprising a part with four panels forming a belt and at least one part constituting a bottom wall.

Les emballages connus sous le nom de caisses américaines sont largement utilisés pour le stockage et le transport d'articles de consommation courante. Les caisses comprennent une ceinture à quatre panneaux et deux parois, l'une inférieure et l'autre supérieure. Ces dernières sont réalisées, après mise en forme de la ceinture, par pliage de rabats qui prolongent les quatre panneaux de la ceinture. Plus précisément, on dépose des pavés de colle sur la face externe de deux rabats opposés, on les plie à 90° et on plie ensuite les deux autres rabats sur les premiers. Ainsi les quatre rabats se retrouvent solidaires deux par deux, l'un intérieur l'autre extérieur, et forment la paroi de fond. Après chargement, on ferme la caisse de la même façon. Il est certain que ces opérations peuvent être automatisées.The packaging known as American crates is widely used for the storage and transportation of everyday consumer items. The crates include a belt with four panels and two walls, one lower and the other upper. The latter are produced, after shaping the belt, by folding flaps which extend the four panels of the belt. More precisely, glue blocks are deposited on the external face of two opposite flaps, they are folded at 90 ° and then the other two flaps are folded on the first. Thus the four flaps are joined together two by two, one inside the other outside, and form the bottom wall. After loading, the box is closed in the same way. It is certain that these operations can be automated.

Après usage, la caisse est démontée pour faciliter son stockage et son évacuation en vue de sa destruction ou du recyclage du carton, le cas échéant. Dans les magasins à grande surface de vente, le nombre de caisses que le personnel est amené à manipuler peut être très important. Un moyen permettant une remise à plat aisée de ces caisses après qu'elles aient été vidées de leur contenu est donc souhaitable.After use, the box is dismantled to facilitate its storage and evacuation with a view to its destruction or recycling of the cardboard, if necessary. In stores with a large sales area, the number of cases that staff have to handle can be very large. It is therefore desirable to provide a means allowing these cases to be easily flattened out after they have been emptied of their contents.

On connaît par ailleurs des emballages de ce type mais séparables en deux parties, l'une, inférieure, formant une barquette présentoir, l'autre, supérieure, constituant la coiffe que l'on retire sur le lieu de vente des articles contenus dans la barquette. Pour ce modèle d'emballage, il est également souhaitable de pouvoir aisément remettre à plat la coiffe.We also know packaging of this type but separable into two parts, one, lower, forming a display tray, the other, upper, constituting the cap that is removed at the point of sale of the items contained in the tray. For this packaging model, it is also desirable to be able to easily flatten the cap.

La présente invention se propose de résoudre ce problème.The present invention proposes to solve this problem.

Conformément à l'invention, on propose un emballage en carton ou autre matériau semi-rigide du type comprenant quatre parois formant une ceinture et au moins une paroi de fond formée de deux rabats intérieurs parallèles et de deux rabats extérieurs parallèles rendus solidaires par deux, l'un intérieur l'autre extérieur, par des moyens d'attache, caractérisé en ce que la paroi de fond comprend un moyen de pliage selon une diagonale et deux moyens pour désolidariser les rabats intérieurs des rabats extérieurs de part et d'autre de la dite diagonale.In accordance with the invention, a cardboard or other semi-rigid material of the type is proposed comprising four walls forming a belt and at least one bottom wall formed by two parallel inner flaps and two parallel outer flaps joined together in pairs, one inside the other outside, by fastening means, characterized in that the bottom wall comprises a means of folding along a diagonal and two means for separating the inner flaps from the outer flaps on either side of the so-called diagonal.

Un tel emballage peut être aisément mis à plat grâce à la mise en oeuvre combinée des moyens sous l'action d'une simple pression exercée sur la paroi de fond vers l'intérieur.Such packaging can be easily flattened thanks to the combined implementation of the means under the action of a simple pressure exerted on the bottom wall inward.

Les moyens d'attache des rabats entre eux sont constitués de préférence par des pavés de colle, notamment de colle dite hotmelt, appliqués à chaud au moyen de pistolets applicateurs.The means for attaching the flaps to each other preferably consist of blocks of glue, in particular hotmelt glue, applied hot by means of applicator guns.

Le moyen de pliage est constitué par exemple par une découpe alternée réalisée sur au moins l'un des rabats extérieurs à partir de l'un des angles du fond. L'axe de pliage ainsi formé a pour fonction de faciliter le rapprochement en ciseaux des deux parois formant le dit angle. On rend le pliage encore plus aisé si on prévoit une découpe alternée sur le rabat intérieur parallèlement à celle du rabat extérieur. Une découpe alternée est préférée à un simple rainage car elle permet un pliage plus efficace. Le rainage n'est cependant pas à exclure.The folding means consists, for example, of an alternating cut made on at least one of the outer flaps from one of the corners of the bottom. The folding axis thus formed has the function of facilitating the scissors coming together of the two walls forming the said angle. The folding is made even easier if an alternate cutting is provided on the inner flap parallel to that of the outer flap. Alternate cutting is preferred to simple creasing because it allows more efficient folding. Creasing is not to be excluded, however.

Les moyens pour désolidariser les rabats intérieurs des rabats extérieurs de chaque côté de la diagonale sont de préférence constitués par des prédécoupes délimitant une portion détachable des rabats intérieurs. Cette portion comprend le moyen d'attache entre le rabat intérieur et le rabat extérieur correspondant. Ainsi, on facilite l'ouverture de l'angle formé par les deux parois situées d'un même côté de la diagonale.The means for separating the inner flaps from the outer flaps on each side of the diagonal are preferably constituted by pre-cuts delimiting a detachable portion of the inner flaps. This portion includes the attachment means between the inner flap and the corresponding outer flap. Thus, it facilitates the opening of the angle formed by the two walls located on the same side of the diagonal.

Un avantage particulier de la solution de l'invention est qu'elle ne modifie pas la découpe du carton. L'utilisateur peut mettre en volume cet emballage comme un emballage traditionnel sans avoir à modifier son installation de formation et fermeture des rabats.A particular advantage of the solution of the invention is that it does not modify the cutting of the cardboard. The user can volume this packaging like a traditional packaging without having to modify his training facility and closing the flaps.

D'autres avantages et caractéristiques apparaîtront à la lecture de la description qui suit d'un mode de réalisation de l'invention en référence aux dessins annexés sur lesquelles :

  • La figure 1 représente une plaque de carton pour la formation d'une caisse américaine comprenant les caractéristiques de la présente invention.
  • La figure 2 représente la caisse réalisée à partir de la plaque de carton selon la figure 1.
  • La figure 3 représente une plaque de carton pour la réalisation d'un emballage présentoir incorporant les caractéristiques de la présente invention.
Other advantages and characteristics will appear on reading the following description of an embodiment of the invention with reference to the appended drawings in which:
  • FIG. 1 represents a cardboard plate for the formation of an American box comprising the characteristics of the present invention.
  • FIG. 2 represents the box made from the cardboard plate according to FIG. 1.
  • FIG. 3 represents a cardboard plate for producing a display packaging incorporating the characteristics of the present invention.

On a représenté sur la figure 1 une plaque 1 de carton ou autre matériau équivalent, découpée et rainée pour former une caisse américaine. Celle-ci, après montage, a été représentée à la figure 2. La plaque 1 comprend, comme cela est bien connu, des panneaux 2, 4, 6, 8, délimités par les rainages respectifs 21, 24, 46, 68 (représentés par des traits interrompus) et le bord 85, ainsi qu'un tenon 3 entre le rainage 21 et le bord. De part et d'autre de cet alignement, les panneaux 2, 4, 6, 8 sont prolongés respectivement par des panneaux 21, 22, 41, 42, 61, 62, 81, et 83. A la mise en volume de la caisse, on forme d'abord la ceinture en pliant les panneaux autour des rainages et en fixant le tenon 3 au panneau 8 le long du bord 85, par collage ou agrafage. Pour former le fond, on rabat à 90° les panneaux 22 et 62 qui constituent alors les rabats intérieurs. On dépose de la colle sur ces deux rabats, par exemple deux pavés de colle hotmelt, chacun dans une zone à proximité des angles libres. On plie ensuite les deux autres rabats en les maintenant appuyés contre les deux premiers le temps que la colle durcisse. Les rabats 42, 82 constituent les rabats extérieurs. Ainsi les pavés de colle constituent les moyens d'attache des rabats entre eux. Les rabats sont solidaires par deux, c'est-à-dire un rabat intérieur avec un rabat extérieur. On a ainsi quatre liaisons : 22/42, 22/82, 62/42 et 62/82.There is shown in Figure 1 a plate 1 of cardboard or other equivalent material, cut and grooved to form an American box. This, after assembly, has been shown in Figure 2. The plate 1 comprises, as is well known, panels 2, 4, 6, 8, delimited by the respective grooves 21, 24, 46, 68 (shown by broken lines) and the edge 85, as well as a stud 3 between the creasing 21 and the edge. On either side of this alignment, the panels 2, 4, 6, 8 are extended respectively by panels 21, 22, 41, 42, 61, 62, 81, and 83. When the body is placed in volume , the belt is first formed by folding the panels around the grooves and fixing the post 3 to the panel 8 along the edge 85, by gluing or stapling. To form the bottom, the panels 22 and 62 which constitute then the interior flaps. Glue is deposited on these two flaps, for example two blocks of hotmelt glue, each in an area close to the free angles. Then fold the other two flaps, keeping them pressed against the first two until the glue hardens. The flaps 42, 82 constitute the outer flaps. Thus the adhesive pavers constitute the means for attaching the flaps together. The flaps are joined in pairs, that is to say an inner flap with an outer flap. There are thus four connections: 22/42, 22/82, 62/42 and 62/82.

Après chargement, on procède de la même façon pour fermer la caisse. Il est possible également d'utiliser un ruban adhésif ou un autre moyen pour la fermeture.After loading, we proceed in the same way to close the box. It is also possible to use an adhesive tape or other means for closing.

Conformément à l'invention, on a ménagé sur cette plaque de carton des moyens destinés à faciliter la mise à plat de la caisse après usage.In accordance with the invention, means have been provided on this cardboard plate to facilitate the flattening of the box after use.

On a ménagé un moyen de pliage préférentiel du rabat extérieur 42. Celui-ci est constitué par une découpe alternée 43 rectiligne du rabat 42, tracée depuis l'angle adjacent au rainage 24 jusqu'à son bord libre. Par prédécoupe ou découpe alternée, on entend la découpe de la plaque le long d'une succession de segments séparés par des zones non découpées et constituant des tenons ou points d'attache. Dans le cas d'une découpe alternée les points d'attache sont plus longs que dans la prédécoupe. Cette découpe 43 forme un angle alpha avec le bord du rabat situé dans le prolongement du rainage 24. Cet angle vaut par exemple 45° mais il peut en dévier sensiblement. On a ménagé une deuxième découpe alternée 83, identique à la première, sur le rabat 82 qui est non adjacent au rabat 42. Cette prédécoupe forme le même angle alpha avec le bord du rabat 82 situé dans l'alignement du rainage 68. Afin de rendre le pliage plus aisé, on prévoit également deux découpes alternées, 23' et 63' respectivement, sur les rabats 22 et 62. Elles forment un angle alpha avec le rainage délimitant leur rabat respectifA preferential folding means has been provided for the outer flap 42. This consists of an alternating straight cut 43 of the flap 42, traced from the angle adjacent to the creasing 24 to its free edge. By precut or alternate cutting is meant cutting the plate along a succession of segments separated by uncut areas and constituting tenons or attachment points. In the case of alternating cutting, the attachment points are longer than in the precut. This cut 43 forms an angle alpha with the edge of the flap located in the extension of the creasing 24. This angle is for example 45 ° but it can deviate substantially. A second alternating cut 83, identical to the first, has been provided on the flap 82 which is not adjacent to the flap 42. This precut forms the same angle alpha with the edge of the flap 82 situated in alignment with the creasing 68. In order to make folding easier, two alternate cuts are also provided, 23 'and 63' respectively, on the flaps 22 and 62. They form an alpha angle with the creasing delimiting their respective flap

On a ménagé également un moyen 23 de désolidarisation des rabats 22 et 82 et un moyen 63 de désolidarisation des rabats 62 et 42. Ces moyens 23 et 63 sont constitués par des prédécoupes qui délimitent une portion, 25 et 65 respectivement, susceptible d'être détachée du rabat. Cette portion s'étend sur le rabat, 22 resp. 62, de telle sorte que le moyen d'attache, 22/82 resp. 62/42, soit compris dans la zone ainsi délimitée.A means 23 for separating the flaps 22 and 82 and a means 63 for separating the flaps 62 and 42 have also been provided. These means 23 and 63 are formed by precuts which delimit a portion, 25 and 65 respectively, capable of being detached from the flap. This portion extends over the flap, 22 resp. 62, so that the attachment means, 22/82 resp. 62/42, that is to say included in the zone thus delimited.

La mise en volume de la caisse conforme à l'invention n'est pas différente de celle qui a été décrite ci-dessus. On a représenté à la figure 2 la caisse retournée de façon à voir la paroi de fond. Les rabats intérieurs 22 et 62 sont visibles par transparence.The volume of the box according to the invention is no different from that which has been described above. FIG. 2 shows the body turned over so as to see the bottom wall. The inner flaps 22 and 62 are visible by transparency.

Lorsque après usage, on souhaite mettre la caisse à plat, il suffit d'exercer une pression sur le fond dans le sens de la flèche; par exemple un coup de poing. Les moyens d'attache constitués par les pavés de colle sont prévus pour résister aux contraintes ainsi créées. Cependant, en raison des prédécoupes 23 et 63, les points d'attache reliant les portions 25 et 65 à leur rabat 22, 62 respectif cèdent, et autorisent la rotation des rabats autour de leur rainage respectif. Ces portions 25 et 65 restent solidaires des rabats 42 et 82 respectivement En continuant à exercer la pression sur le fond, on amène chaque rabat contre le panneau auquel il est attaché. Ce mouvement est guidé par les deux lignes 43 et 83 autour desquelles pivotent les rabats 22 et 42 d'une part, et 62 et 82 d'autre part. A la fin du mouvement le ciseau formé par les panneaux 6 et 8 est fermé ainsi que celui formé par les panneaux 2 et 4. La mise à plat est achevée. Afin de faciliter le pivotement des rabats en réduisant la résistance due aux frottements contre les parois adjacentes, on peut prévoir des rainages auxiliaires 26, 46, 66, 86.When after use, you want to put the box flat, it suffices to apply pressure on the bottom in the direction of the arrow; for example a punch. The attachment means constituted by the adhesive pavers are provided to resist the stresses thus created. However, due to the precuts 23 and 63, the points attachment connecting the portions 25 and 65 to their respective flap 22, 62 give way, and allow the rotation of the flaps around their respective creasing. These portions 25 and 65 remain integral with the flaps 42 and 82 respectively. By continuing to exert pressure on the bottom, each flap is brought against the panel to which it is attached. This movement is guided by the two lines 43 and 83 around which the flaps 22 and 42 pivot on the one hand, and 62 and 82 on the other hand. At the end of the movement the chisel formed by the panels 6 and 8 is closed as well as that formed by the panels 2 and 4. The flattening is completed. In order to facilitate pivoting of the flaps by reducing the resistance due to friction against the adjacent walls, auxiliary grooves 26, 46, 66, 86 can be provided.

On a représenté sur la figure 3 une plaque de carton permettant la réalisation d'un emballage présentoir ainsi que cela est décrit dans la demande de brevet EP 93402026. Cette plaque présente l'avantage de pouvoir être mise en volume de la même façon qu'une caisse américaine ordinaire. On applique la présente invention de manière avantageuse à la partie I de la caisse qui constitue la coiffe de l'emballage. Celle-ci peut être mise à plat après avoir été détachée de la portion II formant barquette présentoir.There is shown in FIG. 3 a cardboard plate allowing the production of a display packaging as described in patent application EP 93402026. This plate has the advantage of being able to be set in volume in the same way as an ordinary American fund. The present invention is advantageously applied to part I of the box which constitutes the cover of the packaging. This can be flattened after being detached from the portion II forming a display tray.
