Abstract

In this box, the opening of each lateral wall (12) is parallel to the groove line (10) between the wall (12) and the base (6), while attachment lugs (14) project from the lateral edges of the upper wall portions (8) and form hooks oriented in the direction of the longitudinal wall (7), these hooks being separated from the groove line (4) by a distance (1) which is less than that (L) so that, after the box has been made up and the lugs (14) have been inserted in the openings (15), the elasticity of the tabs (13) ensures attachment of these lugs over the edges of the openings. <IMAGE>

Description

L'invention est relative à une boîte portable et empilable.The invention relates to a portable and stackable box.

Elle vise plus particulièrement les boîtes réalisées à partir d'un flan dans lequel des lignes de rainage délimitent,de part et d'autre d'un fbnd,d'une part,longitudinalement,une paroi longitudinale,une portion de paroi supérieure et une poignée,d'autre part,latéralement,une paroi latérale et,de plus,des languettes saillant des parois latérales ou longitudinales ,ces divers éléments étant assemblés par introduction de pattes d'accrochage s'engageant dans des ouvertures des parois latérales.It relates more particularly to the boxes produced from a blank in which creasing lines delimit, on either side of an fbnd, on the one hand, longitudinally, a longitudinal wall, an upper wall portion and a handle, on the other hand, laterally, a side wall and, moreover, tongues projecting from the side or longitudinal walls, these various elements being assembled by introduction of hooking lugs engaging in openings in the side walls.

En général,dans ce type de boîte,et comme décrit dans le brevet français 940.449, les pattes d'accrochage sont disposées à l'extrémité des poignées et les ouvertures ménagées dans les parois latérales sont verticales,afin que le poids du contenu reposant sur le fond se transmette aux poignées par l'intermédiaire des parois latérales et desdites pattes d'accrochage.Ce mode d'assemblage,qui améliore la répartition de la charge lorsque la boite est portée, conduit à des inconvénients lorsque celle-ci est posée.En effet,dans ces conditions,le fond et les parois latérales ne transmettent pas la charge aux poignées,de sorte que les parois longitudinales,à l'extrémité desquelles les poignées sont ménagées,tendent à bailler,c'est-à-dire à former des ouvertures dans leur partie jouxtant les parois latérales. Ces ouvertures déparent l'aspect général de l'emballage, même lorsque les parois longitudinales ou latérales sont munies de languettes d'obturation.In general, in this type of box, and as described in French patent 940,449, the hanging tabs are arranged at the end of the handles and the openings in the side walls are vertical, so that the weight of the content rests on the bottom is transmitted to the handles via the side walls and said attachment tabs. This method of assembly, which improves the distribution of the load when the box is carried, leads to drawbacks when it is placed. Indeed, under these conditions, the bottom and the side walls do not transmit the load to the handles, so that the longitudinal walls, at the end of which the handles are arranged, tend to yawn, that is to say to form openings in their part adjoining the side walls. These openings deviate from the general appearance of the packaging, even when the longitudinal or lateral walls are provided with closure tabs.

Par ailleurs,la liaison des poignées avec les parois latérales,liaison obligeant les premières à rester perpendiculaires à la paroi supérieure de la boite,interdit tout pliage de ces poignées et empêche donc l'empilage de telles boîtes.Furthermore, the connection of the handles with the side walls, connection forcing the former to remain perpendicular to the upper wall of the box, prohibits any folding of these handles and therefore prevents stacking of such boxes.

La présente invention a pour but de fournir une boîte qui remédie à ces inconvénients,c'est-à-dire ait une excel- lente présentation,qu'elle soit portée ou posée,et puisse être empilée si cela s'avère nécessaire pour stocker son contenu.The present invention aims to provide a box which overcomes these drawbacks, that is to say have a exce l - slow presentation, whether carried or placed, and can be stacked if necessary to store its content.

Dans la boite selon l'invention,l'ouverture de chaque paroi latérale est parallèle à la ligne de rainage entre cette paroi et le fond,tandis que les pattes d'accrochage font saillie des bords latéraux des portions de paroi supérieure et forment des crochets orientés en direction de la paroi longitudinale correspondante,crochets dont le fond est séparé de la ligne de rainage,entre la portion de paroi supérieure et la paroi longitudinale correspondante,par une distance 1 inférieure à celle L séparant le bord de l'ouverture du bord juxtaposé de la paroi dans laquelle cette dernière est ménagée,afin qu'après formage de la boite et introduction des pattes dans les ouvertures, l'élasticité des languettes assure l'accrochage de ces pattes sur les bords des ouvertures.In the box according to the invention, the opening of each side wall is parallel to the crease line between this wall and the bottom, while the hooking tabs protrude from the side edges of the upper wall portions and form hooks oriented towards the corresponding longitudinal wall, hooks the bottom of which is separated from the crease line, between the upper wall portion and the corresponding longitudinal wall, by a distance 1 less than that L separating the edge from the edge opening juxtaposed with the wall in which the latter is arranged, so that after forming the box and introducing the tabs into the openings, the elasticity of the tabs ensures the attachment of these tabs on the edges of the openings.

Grâce à cet agencement,la mise en place des pattes d'accrochage dans les ouvertures des'parois latérales nécessite de comprimer légèrement les languettes solidaireso des parois latérales ou longitudinales.Cette compression entraine,grâce à l'élasticité de la matière constitùtive du flan,une réaction qui,lorsque les pattes d'accrochage sont engagées dans les fentes,sollicite en traction les portions de paroi supérieure et oblige le fond des pattes d'accrochage à venir en contact avec le bord des ouvertures.De la sorte,à l'état posé,l'emballage a exactement la même forme que lorsqu'il est porté.With this arrangement, the installation of fastening tabs in the side openings des'parois requires slightly compress the tabs integral o sidewalls or longitudinales.Cette compression causes, thanks to the elasticity of the constituent material of the blank , a reaction which, when the fastening tabs are engaged in the slots, tensile stresses the upper wall portions and forces the bottom of the fastening tabs to come into contact with the edge of the openings. Once installed, the packaging has exactly the same shape as when it was worn.

Par ailleurs,la disposition des pattes d'accrochage dans le prolongement des portions de paroi supérieure permet de rendre les poignées totalement indépendantes des parois latérales,ce qui permet de rabattre ces poignées contre les portions de paroi supérieure lorsque l'emballage doit être empilé et permet donc de former avec cette boîte des piles stables,ce qui n'est pas le cas avec les boîtes de type traditionnel.Furthermore, the arrangement of the hooking lugs in the extension of the upper wall portions makes it possible to make the handles completely independent of the side walls, which makes it possible to fold these handles against the upper wall portions when the packaging is to be stacked and therefore allows stable batteries to be formed with this box, which is not the case with traditional type boxes.

A la figure 1, 2 désigne un flan réalisé en carton ou tout autre matériau.Des lignes de rainage 3,4 et 5 délimitent dans ce flan et,de part et d'autre d'un fond 6,des parois longitudinales 7, des portions de paroi supérieure 8 et des poignées 9.Le fond 6 est séparé,par des lignes de rainage 10,de deux parois latérales 12 munies chacune de languettes 13.In FIG. 1, 2 denotes a blank made of cardboard or any other material. Creasing lines 3, 4 and 5 delimit in this blank and, on either side of a bottom 6, longitudinal walls 7, upper wall portions 8 and handles 9. The bottom 6 is separated, by creasing lines 10, from two side walls 12 each provided with tongues 13.

Selon l'invention,chacune des portions de paroi supérieure comporte,en saillie de ses bords latéraux,des pattes d'accrochage 14 formant des crochets orientés en direction des parois longitudinales 7. En outre,les parois latérales 12 comportent chacune au moins une ouverture 15 qui,parallèle à'la ligne de rainage 10 correspondante,est disposée sensiblement au milieu de cette paroioAccording to the invention, each of the upper wall portions comprises, projecting from its lateral edges, hooking lugs 14 forming hooks oriented in the direction of the longitudinal walls 7. In addition, the lateral walls 12 each comprise at least one opening 15 which, parallel to the corresponding creasing line 10, is arranged substantially in the middle of this wall

Chaque ouverture 15 est séparée de la ligne de rainage 10 par une distance d sensiblement égale à la hauteur h des parois longitudinales 4. En outre,la distance L séparant le bord de chaque ouverture 15 du bord juxtaposé de la paroi latérale dans laquelle elle est ménagée,est supérieure à la distance 1 entre la ligne de rainage 4 et le fond du crochet formé par la patte d'accrochage correspondante.Les pattes d'accrochage sont à proximité de la ligne de rainage séparant la portion de paroi supérieure de la poignée correspondante.Each opening 15 is separated from the crease line 10 by a distance d substantially equal to the height h of the longitudinal walls 4. In addition, the distance L separating the edge of each opening 15 from the juxtaposed edge of the side wall in which it is formed, is greater than the distance 1 between the crease line 4 and the bottom of the hook formed by the corresponding hooking tab. The hooking tabs are close to the crease line separating the upper wall portion of the corresponding handle.

Pour monter cette boîte,il suffit de plier les languettes 13 perpendiculairement aux parois latérales 12, puis de rabattre ces parois,comme montré à la figure 2, tandis que,simultanément,les parois longitudinales 7 et les portions de paroi supérieure 8 sont pliées et ramenées l'une contre l'autre.Pour mettre en place les pattes d'accrochage 14 dans les ouvertures 15,il est nécessaire de communiquer aux poignées 9 et aux portions de paroi supérieure 8 un déplacement dans le sens de la flèche 25 de figure 3. Ce déplacement tend à faire rentrer la paroi longitudinale 7 correspondante entre les deux parois latérales 12 et tend donc à cintrer,vers l'intérieurm, les languettes 13 correspondantes.Dès que les pattes d'accrochage 14 sont engagées dans les ouvertures 15, les languettes 13 tendent,par élasticité,à communiquer à la portion de paroi supérieure 8 correspondante un déplacement dans le sens de la flèche 26 de figure 5,déplacement ayant pour effet d'amener le fond du crochet formé par les pattes d'accrochage contre le bord de la découpe 15 et,en conséquence, d'affirmer le verrouillage assuré par les pattes 14.Pour faciliter l'engagement des pattes d'accrochage,chacune des portions de paroi supérieure a une longueur inférieure à la moitié de la longueur du fondoTo mount this box, it suffices to fold the tabs 13 perpendicularly to the side walls 12, then to fold down these walls, as shown in FIG. 2, while, simultaneously, the longitudinal walls 7 and the upper wall portions 8 are folded and brought against each other. To put the hooking lugs 14 in the openings 15, it is necessary to communicate to the handles 9 and to the upper wall portions 8 a movement in the direction of the arrow 25 in the figure. 3. This movement tends to bring in the corresponding longitudinal wall 7 between the two side walls 12 and therefore tends to bend, inwardly, the corresponding tongues 13. As soon as the lugs 14 are engaged in the openings 15, the tongues 13 tend, by elasticity, to communicate to the corresponding upper wall portion 8 a displacement in the direction of the arrow 26 of FIG. 5, displacement having the effect of bringing the bottom of the hook formed by the lugs against the edge of the cutout 15 and, therefore, to confirm the locking provided by the lugs 14. To facilitate the engagement of the lugs, each of the upper wall portions has a length less than half the length of the fondo

A la fin de l'opération de montage,et que la boîte soit chargée ou non,elle présente une forme parallélépipédique régulière.Cette régularité est obtenue grâce à la différence de longueur entre les distances L et 1 précisées plus haut,différence qui peut être de l'ordre de 1 à quelques millimètres en fonction des caractéristiques élastiques des languettes 13,donc des caractéristiques du matériau constituant le flan à partir duquel l'emballage est réaliséoAt the end of the assembly operation, and whether the box is loaded or not, it has a regular parallelepiped shape. This regularity is obtained thanks to the difference in length between the distances L and 1 specified above, difference which can be in the range of 1 to a few millimeters depending on the elastic characteristics of the tongues 13, therefore on the characteristics of the material constituting the blank from which the packaging is made.

Il est à noter que,grâce à la disposition horizontale des pattes d'accrochage 14,les deux poignées 9 sont absolument indépendantes de la partie supérieure 12a des parois latérales 12 et peuvent donc être rabattues contre les portions de paroi supérieure 8,comme montré en traits mixtes à la figure 3.Ce rabattement permet,comme montré à la figure 4,d'empiler sans aucun problème plusieurs boites selon l'invention et permet donc d'utiliser ces boites pour l'emballage de produits non comestibles nécessitant un stockage par empilage,telle que de la lingerie.Il est évident que les proportions et les formes des différentes parois peuvent varier en fonction de la nature des produits à emballer et des goûts des consommateursoIt should be noted that, thanks to the horizontal arrangement of the hooking lugs 14, the two handles 9 are absolutely independent of the upper part 12a of the side walls 12 and can therefore be folded against the upper wall portions 8, as shown in dashed lines in Figure 3.This fold allows, as shown in Figure 4, stack without problem several boxes according to the invention and therefore allows these boxes to be used for packaging inedible products requiring storage by stacking, such as lingerie. It is obvious that the proportions and shapes of the different walls can vary depending on the nature of the products to be packaged and the tastes of consumers.

Dans la variante de réalisation représentée aux figures 6 à 8,les poignées 2 sont prolongées latéralement,de manière à présenter,dans le prolongement des pattes d'accrochage 14, des pattes d'accrochage 30 dont les ouvertures 31 sont opposées à celles des pattes 14 précitées.En outre, chacune des ouvertures 12 des parois latérales 12 comporte,sensiblement à mi-longueur,une fente verticale 32 ménagée dans une découpe arrondie 33.De la sorte,lorsque la boîte est montée comme montré à la figure 7, les ouvertures 31 de chacune des pattes 30 peuvent coopérer avec les fentes 32 pour assurer le positionnement et le maintien des poignées 90In the embodiment shown in Figures 6 to 8, the handles 2 are extended laterally, so as to present, in the extension of the lugs 14, lugs 30 whose openings 31 are opposite to those of the lugs In addition, each of the openings 12 of the side walls 12 comprises, substantially at mid-length, a vertical slot 32 formed in a rounded cutout 33. In this way, when the box is mounted as shown in FIG. 7, the openings 31 of each of the legs 30 can cooperate with the slots 32 to ensure the positioning and the maintenance of the handles 90

Ces moyens d'accrochage améliorent la rigidité générale de l'emballage et empêchent que,sous les effets du poids de son contenu,les deux poignées aient tendance à se cintrer lorsqu'elles sont saisies pour soulever l'emballage .These attachment means improve the general rigidity of the packaging and prevent the two handles from tending to bend under the effects of the weight of its contents when they are grasped to lift the packaging.

La figure 8 montre que ces moyens de liaison des poignées avec les parois latérales 12 permettent néanmoins de rabattre les poignées 9 sur les portions de paroi supérieure 8,notamment pour permettre son empilage.Ce rabattement est rendu possible,grâce à la découpe arrondie 33 autorisant le pivotement des poignées lorsque leurs ouvertures 31 sont désengagées des fentes 32. A cette fin,le rayon de la découpe 33 est supérieur à la distance e (figure 6) séparant le fond des ouvertures 31 des pattes d'accrochage 30 de la ligne de rainage 5 entre chaque poignée et la portion supérieure 8 correspondanteoFIG. 8 shows that these means of connecting the handles with the side walls 12 nevertheless make it possible to fold the handles 9 onto the wall portions upper 8, in particular to allow it to be stacked. This folding is made possible, thanks to the rounded cut 33 allowing the handles to pivot when their openings 31 are disengaged from the slots 32. To this end, the radius of the cut 33 is greater than the distance e (FIG. 6) separating the bottom of the openings 31 of the hooking lugs 30 of the crease line 5 between each handle and the corresponding upper portion 8

Exceptées ces différences de détail,cette boite est en tous points similaire à celle décrite dans la forme d'exécution antérieure.Except for these differences in detail, this box is in all respects similar to that described in the previous embodiment.

La boîte décrite en référence aux figures 9 à 11 se différencie des précédentes,d'une part,par ses languettes 34 qui sont ménagées dans le prolongement des parois longitudinales 7 et,d'autre part,par la présence de lignes de rainage 35 sur les parois latérales 12. Ainsi,chaque paroi latérale est divisée,par deux lignes de rainage 35 délimitant une sorte de V,en un volet central 12a et deux volets latéraux 12b.Les volets latéraux reçoivent,après découpage du flan 2a ,une certaine quantité de produit adhésif 36 .Ce produit est disposé localement sur la face des volets qui correspond normalement à l'intérieur de la boîte. Avant stockage,la boîte est prémontée ,c'est-à-dire que ses languettes 34 sont appliquées contre les zones encollées. Après séchage du produit adhésif,les deux volets centraux 12a des parois latérales se rabattent contre le fond 6 de la boîte. Durant ce mouvement,et comme montré à la figure 10,les volets latéraux 12b,basculant autour de lignes de rainage 35, viennent en contact avec la face extérieure d'un volet central 12a correspondant , tandis que les languettes 34 s'intercalent chacune entre la portion de paroi supérieure 8 correspondante et le volet latéral 12b auquel elle est liée .The box described with reference to Figures 9 to 11 differs from the previous ones, on the one hand, by its tongues 34 which are formed in the extension of the longitudinal walls 7 and, on the other hand, by the presence of crease lines 35 on the side walls 12. Thus, each side wall is divided, by two crease lines 35 delimiting a sort of V, into a central flap 12a and two side flaps 12b. The side flaps receive, after cutting the blank 2a, a certain amount adhesive product 36. This product is placed locally on the face of the flaps which normally corresponds to the inside of the box. Before storage, the box is pre-assembled, that is to say that its tongues 34 are applied against the glued areas. After the adhesive product has dried, the two central flaps 12a of the side walls fold back against the bottom 6 of the box. During this movement, and as shown in FIG. 10, the side flaps 12b, tilting around creasing lines 35, come into contact with the outside face of a corresponding central flap 12a, while the tongues 34 are each inserted between the corresponding upper wall portion 8 and the side flap 12b to which it is linked.

Après pliage pour stockage à plat,la boite présente ainsi la forme représentée à la figure 11.After folding for flat storage, the box thus has the shape shown in FIG. 11.

Pour amener la boite dans sa forme d'utilisation,il suffit de saisir les deux volets centraux 12a et de les éloigner du fond 6 dans le sens des flèches 37 de figure 11. Cette simple opération assure la formation de la partie inférieure de la boîte qui,après remplissage,est fermée grâce aux pattes d'accrochage 14 et 30 pénétrant dans les ouvertures 32 et 33 ménagées dans les volets centraux. Il est à noter que,là encore,les pattes 14 sont verrouillées par l'élasticité des languettes 34,élasticité aidée par la liaison de ces languettes avec les volets latéraux 12b.To bring the box into its form of use, it suffices to grasp the two central flaps 12a and to move away from the bottom 6 in the direction of the arrows 37 in FIG. 11. This simple operation ensures the formation of the lower part of the box which, after filling, is closed by means of the hooking lugs 14 and 30 penetrating into the openings 32 and 33 arranged in the central shutters. It should be noted that, here again, the tabs 14 are locked by the elasticity of the tongues 34, elasticity aided by the connection of these tongues with the side flaps 12b.
