The two small lateral faces 7 are each extended, on either side, by two articulated flaps 8 glued to the ends of the two large lateral faces 3; the latter comprise oblique folding lines 4 starting from the corners 12 of the bottom 1 and delimiting triangular sections 5. The articulated flaps 8 each have, on their bottom edge 11, a locking tab 10 which, in the deployed position of the box, is retained on the folding line 2 by which the bottom 1 is connected to one of the large lateral faces 3. Application: shoe boxes.

Description

La présente invention concerne une boîte en carton, de forme générale parallélépipédique, formée d'un fond rectangulaire et de quatre faces latérales articulées respectivement le long des quatre côtés du fond, les deux petites faces latérales étant prolongées chacune, de part et d'autre, par deux volets articulés collés respectivement aux extrémités des deux grandes faces latérales, ces dernières comportant des lignes de pliage obliques partant des angles du fond et délimitant des parties triangulaires. The present invention relates to a cardboard box, of generally parallelepiped shape, formed of a rectangular bottom and four side faces articulated respectively along the four sides of the bottom, the two small side faces being extended each on either side. , by two articulated flaps respectively glued to the ends of the two large lateral faces, the latter comprising oblique fold lines starting from the corners of the bottom and delimiting triangular parts.

Une boîte en carton de ce genre peut être stockée à plat, donc sous un faible encombrement, ses quatre faces latérales étant rabattues contre le fond, et être déployée seulement au moment de son rernplissage. Il s'agit, par exemple, d'une boîte en carton destinée à recevoir une paire de chaussures. A cardboard box of this kind can be stored flat, so in a small footprint, its four side faces being folded against the bottom, and be deployed only at the time of its rernplissement. It is, for example, a cardboard box intended to receive a pair of shoes.

Une difficulté rencontrée avec ce genre de boîte en carton est le maintien de celle-ci en position déployée. Dans ce but, on a déjà envisagé des systèmes de languettes s'introduisant dans des fentes de blocage ménagées en bordure du fond de la boîte. En raison de la présence de ces fentes, traversées par les languettes, les boîtes en question présentent un aspect peu esthétique, et ces boîtes risquent de s'accrocher les unes aux autres, notamment si elles sont empilées, en raison du dépassement des languettes. A difficulty encountered with this kind of cardboard box is the maintenance of the latter in the deployed position. For this purpose, it has already been envisaged systems of tabs which are introduced into blocking slots provided at the edge of the bottom of the box. Due to the presence of these slots, through which the tongues, the boxes in question have an unattractive appearance, and these boxes may cling to each other, especially if they are stacked, due to the protrusion of the tabs.

La présente invention vise à éliminer ces inconvénients. The present invention aims to eliminate these drawbacks.

A cet effet, l'invention a pour objet une boîte en carton, appartenant au genre défini plus haut, dans laquelle les volets articulés qui prolongent les deux petites faces latérales et qui sont collés aux extrémités des deux grandes faces latérales présentent chacun, sur leur bord inférieur, au moins un ergot de blocage tourne vers le fond de la boîte et apte à être retenu, dans la position déployée de cette boîte, sur la ligne de pliage par laquelle le fond se raccorde à l'une des grandes faces latérales. To this end, the invention relates to a cardboard box, belonging to the genre defined above, in which the hinged flaps which extend the two small side faces and which are glued to the ends of the two large side faces each have, on their lower edge, at least one locking lug turns towards the bottom of the box and capable of being retained, in the deployed position of this box, on the fold line by which the bottom is connected to one of the large lateral faces.

Ainsi on réalise un système de blocage des quatre volets articulés qui ne nécessite aucune fente, ce qui confère à la boîte un aspect définitif plus agréabie et, en supprimant tout dépassement des ergots à l'extérieur, évite aussi que les boîtes ne s'accrochent entre elles. Thus a blocking system for the four articulated flaps is produced which requires no slits, which gives the box a more pleasant final appearance and, by eliminating any protrusion of the pins on the outside, also prevents the boxes from catching on between them.

Selon une forme de réalisation préférée de l'invention, chaque volet articulé comporte un seuil ergot de blocage formé à-l'extrémité du bord inférieur du volet la plus éloignée de l'angle correspondant du fond, et ce bord inférieur suit une ligne légèrement montante entre l'angle et l'ergot. According to a preferred embodiment of the invention, each articulated flap has a locking pin threshold formed at the end of the lower edge of the flap furthest from the corresponding angle of the bottom, and this lower edge follows a slightly rising between the angle and the lug.

De toute façon, I'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette boîte en carton
Figure I représente un flan de carton, à partir duquel est réalisable la boîte conforme à l'invention ;
Figure 2 montre, en perspective, cette boîte en cours de déploiement ;
Figure 3 est une vue en perspective de la même boîte, entièrement déployée.In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this cardboard box
Figure I shows a cardboard blank, from which the box according to the invention can be produced;
Figure 2 shows, in perspective, this box being deployed;
Figure 3 is a perspective view of the same box, fully deployed.

Comme le montre la figure 1, la boîte en carton objet de l'invention est réalisée à partir d'un flan, possédant une partie centrale rectangulaire (1) destinée à former le fond de la boîte. Le long des deux côtés longitudinaux (2) du fond (1) sont articulées les deux grandes faces latérales (3) de la boîte. Sur chaque grande face latérale (3), vers les extrémités de celle-ci, sont prévues deux lignes de pliage obliques (4), inclinées à 450, qui partent des angles du fond (I ) et s'étendent jusqu'au bord extérieur, et qui délimitent ainsi deux parties triangulaires (5). As shown in Figure 1, the cardboard box object of the invention is made from a blank, having a rectangular central portion (1) intended to form the bottom of the box. Along the two longitudinal sides (2) of the bottom (1) are articulated the two large side faces (3) of the box. On each large lateral face (3), towards the ends thereof, there are two oblique fold lines (4), inclined at 450, which start from the corners of the bottom (I) and extend to the outer edge , and which thus delimit two triangular parts (5).

Le long des deux côtés transversaux (6) du fond (i) sont articulées les deux petites faces latérales (7) de la boîte. Chaque petite face latérale (7) est prolongée, de part et d'autre, par deux volets (8) raccordés à cette face (7) suivant des lignes de pliage (9). Chaque volet articulé (8), de forme approximativement carrée, est collé contre la face intérieure de la partie triangulaire voisine (5) appartenant à l'une des grandes faces latérales (3). Along the two transverse sides (6) of the bottom (i) are articulated the two small side faces (7) of the box. Each small lateral face (7) is extended, on both sides, by two flaps (8) connected to this face (7) along fold lines (9). Each articulated flap (8), of approximately square shape, is glued against the inner face of the neighboring triangular part (5) belonging to one of the large lateral faces (3).

Selon l'invention, chaque volet articulé (8) comporte un ergot de blocage (10), formé sur son bord inférieur (II) et plus précisément à l'extrémité de ce bord (11) éloignée de l'angle correspondant (12) du fond (1). Entre cet angle (12) et l'ergot (Il), le bord inférieur (10) du volet articulé (8) suit une ligne qui n'est pas rigoureusement parallèle au bord supérieur de ce volet (8), mais est au contraire légèrement montante. According to the invention, each articulated flap (8) comprises a locking lug (10), formed on its lower edge (II) and more precisely at the end of this edge (11) distant from the corresponding angle (12) from the bottom (1). Between this angle (12) and the lug (II), the lower edge (10) of the articulated flap (8) follows a line which is not strictly parallel to the upper edge of this flap (8), but is on the contrary slightly rising.

La boîte en carton, ainsi constituée, est initialement stockée à plat, dans une position où:
- les deux grandes faces latérales (3) sont rabattues contre le fond (I)
- ies parties triangulaires (5) sont rabattues contre les parties médianes des grandes faces latérales (3) ;
- les deux petites faces latérales (7) sont appliquées sur les grandes faces latérales (3);
- les volets articulés (8), collés aux parties triangulaires (5), sont repliés sous les petites faces latérales (3).The cardboard box, thus formed, is initially stored flat, in a position where:
- the two large side faces (3) are folded against the bottom (I)
- The triangular parts (5) are folded against the middle parts of the large lateral faces (3);
- the two small side faces (7) are applied to the large side faces (3);
- the articulated flaps (8), glued to the triangular parts (5), are folded under the small side faces (3).

Lorsque l'on désire utiliser la boîte, partant de cette position de stockage, on la déploie comme montré à la figure 2 en relevant simultanément les grandes faces latérales (3) et les petites faces latérales (7), qui pivotent relativement au fond (I), autour des articulations formées par les côtés (2,6) du fond (1). Au cours de ce mouvement, les volets articulés (8) s'écartent des petites faces latérales (7) et tendent à se placer, avec les parties triangulaires (5), dans les plans des parties médianes des grandes faces latérales (3). When it is desired to use the box, starting from this storage position, it is deployed as shown in FIG. 2 by simultaneously raising the large side faces (3) and the small side faces (7), which pivot relative to the bottom ( I), around the joints formed by the sides (2,6) of the bottom (1). During this movement, the articulated flaps (8) move away from the small lateral faces (7) and tend to be placed, with the triangular parts (5), in the planes of the median parts of the large lateral faces (3).

En fin de déploiement, comme représenté sur la figure 3, les quatre faces latérales (3 et 7) sont redressées perpendiculairement au fond (1). Les volets (8), également redressés, sont plaqués entièrement contre les grandes faces latérales (3). Les ergots inférieurs (10), alors tournés vers le fond (1) de la boîte, viennent s'accrocher sur les côtés longitudinaux (2) du fond (1), pour assurer un blocage de l'ensemble. At the end of deployment, as shown in Figure 3, the four side faces (3 and 7) are straightened perpendicular to the bottom (1). The flaps (8), also straightened, are pressed entirely against the large side faces (3). The lower pins (10), then turned towards the bottom (1) of the box, come to hang on the longitudinal sides (2) of the bottom (1), to ensure that the assembly is blocked.

Ces côtés longitudinaux (2) peuvent comporter une rainure plus ou moins marquée assurant une retenue encore meilleure des ergots (10r des volets (8). Pour améliorer encore la retenue des ergots de blocage (10) sur les côtés (2) du fond (I), il peut être prévu que l'angle (0 < ) de chaque partie triangulaire (5) situé vers le fond (1), autrement dit l'angle inférieur de cette partie (5), possède une valeur non pas rigoureusement égale à 45 , mais légèrement inférieure à 45" et égale, par exemple, à 430. Il en résulte qu'en fin de déploiement de la boîte, les deux petites faces latérales (7) se trouvent légèrement inclinées sur la verticale, vers l'intérieur de la boîte, et que les volets (8) rattachés à ces faces (7) occupent eux aussi une position légèrement inclinée, donnant une pression supplémentaire des ergots de blocage (10) sur les côtés (2) du fond (1).These longitudinal sides (2) may have a more or less marked groove ensuring even better retention of the lugs (10r of the flaps (8). To further improve the retention of the locking lugs (10) on the sides (2) of the bottom ( I), it can be provided that the angle (0 <) of each triangular part (5) situated towards the bottom (1), in other words the lower angle of this part (5), has a value which is not strictly equal at 45, but slightly less than 45 "and equal, for example, to 430. As a result, at the end of deployment of the box, the two small lateral faces (7) are slightly inclined towards the vertical, towards the inside the box, and that the flaps (8) attached to these faces (7) also occupy a slightly inclined position, giving additional pressure to the locking pins (10) on the sides (2) of the bottom (1).

On obtient ainsi une boîte en carton de forme parallélépipédique, pouvant recevoir un couvercle adapté, et utilisable par exemple comme boîte à chaussures. A cardboard box of parallelepiped shape is thus obtained, capable of receiving a suitable cover, and usable for example as a shoe box.

Bien entendu, l'invention ne se limite pas à la seule forme d'exécution de cette boîte en carton qui a été décrite ci-dessus, à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe.  Of course, the invention is not limited to the only embodiment of this cardboard box which has been described above, by way of example; on the contrary, it embraces all of the variant embodiments and applications respecting the same principle.
