Description

La présente invention concerne une boîte pour l'emballage et le transport d'objets, par exemple destinée à être fournie par les commerçants à leurs clients, en vue permettre à ces derniers d'emporter leurs achats.The present invention relates to a box for packaging and transporting objects, for example intended to be provided by merchants to their customers, with a view to enabling the latter to carry their purchases.

Par le brevet GB-A-831 456, on connaît déjà un sac pour l'emballage et le transport d'objets comportant une poche comprenant un fond rectangulaire, deux grandes faces planes opposées, deux soufflets latéraux et des moyens de préhension disposés à sa partie opposée au fond. Ces moyens de préhension sont constitués par un système d'ouvertures de rabat, faisant partie intégrante du sac et assurant le rapprochement des bords supérieurs de l'ouverture de la poche et l'obturation de celle-ci, lesdits soufflets étant pourvus de lignes de pliage longitudinales. De par sa matière constitutive, ce sac connu doit comporter des bandes de renfort collées à l'emplacement desdits moyens de préhension, de sorte que son coût est onéreux. Il ne peut être utilisé que pour l'emballage et le transport de produits de luxe. De plus, sa résistance mécanique est limitée et il peut se déchirer lorsque les objets qui y sont enfermés sont lourds et/ou présentent des parties anguleuses. Enfin, il ne peut présenter deux volumes d'emballage différents.By patent GB-A-831,456, a bag is already known for packaging and transporting objects comprising a pocket comprising a rectangular bottom, two large opposite flat faces, two lateral bellows and gripping means arranged at its part opposite the bottom. These gripping means are constituted by a system of flap openings, forming an integral part of the bag and ensuring the approximation of the upper edges of the opening of the pocket and the closing of the latter, said bellows being provided with lines of longitudinal folding. Due to its constituent material, this known bag must include reinforcing strips glued to the location of said gripping means, so that its cost is expensive. It can only be used for the packaging and transport of luxury goods. In addition, its mechanical strength is limited and it can tear when the objects enclosed therein are heavy and / or have angular parts. Finally, it cannot have two different packaging volumes.

Par ailleurs, par le brevet CH-A-591 993, on connaît une boîte en une matière rigide, telle que le carton, présentant une partie inférieure en forme de parallélépipéde et une partie supérieure en forme de toit. Cependant, une telle boîte ne peut offrir qu'un seul volume d'emballage.Furthermore, from patent CH-A-591 993, a box is known of a rigid material, such as cardboard, having a lower part in the form of a parallelepiped and an upper part in the form of a roof. However, such a box can only offer one volume of packaging.

La présente invention a pour objet une boîte pouvant présenter deux volumes d'emballage différents en fonction des objets à transporter et pouvant être fabriquée de façon simple.The present invention relates to a box which can have two different packaging volumes depending on the objects to be transported and which can be manufactured in a simple manner.

A cette fin, selon l'invention, la boîte pour l'emballage et le transport d'objets, du type comportant une poche comprenant un fond rectangulaire ou carré, deux faces principales opposées et deux soufflets latéraux et pourvue de moyens de préhenrion à sa partie opposée audit fond, cette boîte étant réalisée par pliage et collage d'un flanc unique d'une matière rigide telle que le carton et lesdits moyens de Préhension étant constitués par un système d'ouvertures et de rabat, faisant partie intégrante dudit flanc et assurant le rapprochement des bords supérieurs de l'ouverture de la poche et l'obturation de celle-ci, lesdits soufflets étant pourvus de lignes de pliage longitudinales, est caractériséeen ce que chaque soufflet est pourvu d'un ensemble intermédiaire de lignes de pliage situe entre fond et la partie supérieure de la boîte deux à deux symétriques par rapport à la ligne de pliage longitudinale correspondante, les jeux intermédiaires de lignes de pliage étant semblables et disposés à la même hauteur à partir du fond de la boîte, pour qu'on puisse donner à la boîte, au choix, soit une section se rétrécissant de façon continue du fond vers les moyens de préhension, soit une section constante entre le fond et lesdits ensembles intermédiaires de lignes de pliage, puis une section se rétrécissant de façon continue desdits ensembles intermédiaires de lignes de pliage vers les moyens de préhension.To this end, according to the invention, the box for packaging and transporting objects, of the type comprising a pocket comprising a rectangular or square bottom, two opposite main faces and two lateral bellows and provided with means for gripping at its part opposite to said bottom, this box being produced by folding and gluing a single flank of a rigid material such as cardboard and said gripping means being constituted by a system of openings and flap, forming an integral part of said flank and ensuring the approximation of the upper edges of the opening of the pocket and the sealing thereof, said bellows being provided with longitudinal fold lines, is characterized in that each bellows is provided with an intermediate set of fold lines located between the bottom and the upper part of the box two by two symmetrical with respect to the corresponding longitudinal fold line, the intermediate sets of fold lines being similar and different placed at the same height from the bottom of the box, so that the box can be given, as desired, either a section narrowing continuously from the bottom to the gripping means, or a constant section between the bottom and said intermediate sets of fold lines, then a continuously narrowing section from said intermediate sets of fold lines to the gripping means.

Ainsi, la boîte selon l'invention peut être réalisée par les machines. de cartonnage connues, ce qui diminue fortement son coût de revient. De plus, étant réalisée en carton, sa résistance mécanique est bonne et à cause de ses lignes de pliage intermédiaires, elle peut présenter deux volumes d'emballage différents.Thus, the box according to the invention can be produced by machines. of known cardboard, which greatly reduces its cost price. In addition, being made of cardboard, its mechanical strength is good and because of its intermediate fold lines, it can have two different packaging volumes.

Le flanc de carton, montré par la figure 1 et destiné à la réalisation d'une boîte selon l'invention, comporte deux faces principales rectangulaires 1 et 2, reliées entre elles par une face latérale 3 dans laquelle sont pratiquées des lignes de prépliage, destinées à donner à ladite face latérale 3 la forme d'un soufflet au moment de l'utilisation de ladite boîte. Pour cela, ces lignes de prépliage comportent deux portions 4a et 4b formant les deux côtés d'un triangle isocèle et prévues au voisinage du fond de la boîte et une portion 4c, médiane à la face 3 et s'étendant sur la plus grande partie de celle-ci. Les faces 1 et 2 sont respectivement reliées à la face 3 par des lignes de prépliage 5 et 6 parallèles entre elles et à la ligne de prépliage 4c. Du côté opposé à la face latérale 3, la face principale 1 est reliée par une autre ligne de Prépliage 7 parallèle aux lignes de prépliage 5 et 6, à une autre face latérale 8, identique à la face latérale 3 et pourvue comme elle de lignes de prépliage 9a, 9b et 9c, destinées à lui permettre de prendre, en utilisation, la forme d'un soufflet et correspondant respectivement aux lignes de prépliage 4a, 4b et 4c. Par ailleurs, du côté opposé à la face latérale 3, la face principale 2 est reliée, par une autre ligne de prépliage 10 parallèle aux lignes de Prépliage 5, 6 et 7, à un volet 11, destiné à être collé sur le côte intérieur de la face latérale 8, pour former la boîte.The cardboard side, shown in FIG. 1 and intended for the production of a box according to the invention, comprises two main rectangular faces 1 and 2, connected together by a lateral face 3 in which are pre-fold lines, intended to give said lateral face 3 the shape of a bellows when said box is used. For this, these pre-folding lines include two portions 4a and 4b forming the two sides of an isosceles triangle and provided in the vicinity of the bottom of the box and a portion 4c, median to the face 3 and extending over most of it. of it. The faces 1 and 2 are respectively connected to the face 3 by pre-folding lines 5 and 6 parallel to each other and to the pre-folding line 4c. On the side opposite to the lateral face 3, the main face 1 is connected by another pre-folding line 7 parallel to the pre-folding lines 5 and 6, to another side face 8, identical to the side face 3 and provided like it with pre-folding lines 9a, 9b and 9c, intended to allow it to take, in use, the form of a bellows and corresponding respectively to the pre-folding lines 4a, 4b and 4c. Furthermore, on the side opposite to the lateral face 3, the main face 2 is connected, by another pre-folding line 10 parallel to the pre-folding lines 5, 6 and 7, to a flap 11, intended to be glued to the inner side. from the side face 8, to form the box.

A la partie inférieure des faces 1, 2, 3 et 8 sont prévus différents volets 12, 13, 14a-14b et 15a-15b articulés autour d'une ligne de prépliage 16 perpendiculaire aux lignes de prépliage 5, 6, 7 et 10 et destinés à former de façon connue un fond automatique, c'est-à-dire un fond susceptible d'être mis à plat dans un plan orthogonal à son propre plan, mais de se former spontanément lorsque l'on écarte l'une de l'autre les faces de la boîte de pliage à laquelle il appartient. A cet effet, les volets 12 et 13 sont rectangulaires, tandis que les volets 14a-14b et 15a-15b présentent des parties 14a et 15a en forme de triangle isocèle et des parties 14b et 15b, respectivement articulées autour d'un côté isocèle desdits triangles et susceptibles d'êrte collées sur les volets 13 et 12.At the lower part of the faces 1, 2, 3 and 8 are provided various flaps 12, 13, 14a-14b and 15a-15b articulated around a pre-folding line 16 perpendicular to the pre-folding lines 5, 6 and 7 and intended to form an automatic bottom in a known manner, that is to say a bottom capable of being laid flat in a plane orthogonal to its own plane, but of forming spontaneously when one moves aside one of the other sides of the folding box to which it belongs. To this end, the flaps 12 and 13 are rectangular, while the flaps 14a-14b and 15a-15b have parts 14a and 15a in the form of an isosceles triangle and parts 14b and 15b, respectively articulated around an isosceles side of the said flaps. triangles and likely to be stuck on flaps 13 and 12.

A la partie supérieure de la face 1 est prévu un rabat 17 articulé à celle-ci au moyen de deux lignes de prépliage espacées 18 et 19, parallèles entre elles et perpendiculaires aux lignes de prépliage 5, 6, 7 et 10.At the upper part of the face 1 is provided a flap 17 articulated thereto by means of two spaced pre-folding lines 18 and 19, parallel to each other and perpendicular to the pre-folding lines 5, 6, 7 and 10.

Dans les faces 1 et 2 et dans le rabat 17 sont prévues des ouvertures 20, 21 et 22 susceptibles de venir en concordance les unes avec les autres lorsque le flanc est mis en forme de boîte et que le rabat 17 est rabattu autor des lignes de prépliage 18 et 19.In the faces 1 and 2 and in the flap 17 are provided openings 20, 21 and 22 capable of coming into concordance with each other when the flank is box-shaped and that the flap 17 is folded over lines of pre-folding 18 and 19.

Dans l'ouverture 22 du rabat 17 est prévue une languette 31, articulée autour d'une ligne de prépliage inférieure 32 s'étendant sur la partie intermédiaire de ladite languette, parallèlement aux lignes de prépliage 18 et 19.In the opening 22 of the flap 17 is provided a tongue 31, articulated around a lower pre-folding line 32 extending over the intermediate part of said tongue, parallel to the pre-folding lines 18 and 19.

Par ailleurs, selon une caractéristique importante de la présente invention, les faces 3 et 8, en plus de leur sysème de lignes de prépliage 4a, 4b, 4c et 9a, 9b 9c leur permettant de prendre la forme de soufflets se rétrécissant du fond vers l'ouverture de la boîte, comportent un ensemble de lignes de pliage intermédiaires 4d, 4e, 4f, 4g et 9d, 9e, 9f, 9g, situé entre le fond et la partie supérieure de la boîte symétriques deux à deux respectivement par rapport aux lignes de prépliage longitudinales médianes 4c ou 9c.Furthermore, according to an important characteristic of the present invention, the faces 3 and 8, in addition to their system of pre-folding lines 4a, 4b, 4c and 9a, 9b 9c allowing them to take the form of bellows narrowing from the bottom towards the opening of the box, include a set of intermediate fold lines 4d, 4e, 4f, 4g and 9d, 9e, 9f, 9g, located between the bottom and the upper part of the box symmetrical two by two respectively with respect to the median longitudinal pre-folding lines 4c or 9c.

On voit ainsi que le flanc de la figure 1 peut aisément, d'une part, être réalisé par les machines usuelles de fabrication de flancs de carton ou de matières analogues, et, d'autre part, être ensuite plié, par exemple autour des lignes de prépliage 6, 7 et 16, pour permettre le collage du volet 11 sur la face 8 et des parties 14b et 15b, respectivement sur les volets 13 et 12. Grâce au fond automatique 12, 13, 14a-14b et 15a-15b on obtient alors un flanc replié à plat et assemblé tel que montré, de l'avant et de l'arrière, par les figures 2 et 3. Dans cette position à plat, les boîtes selon l'invention peuvent être stockées facilement.It can thus be seen that the flank of FIG. 1 can easily, on the one hand, be produced by the usual machines for manufacturing flanks of cardboard or similar materials, and, on the other hand, be then folded, for example around the pre-folding lines 6, 7 and 16, to allow bonding of the flap 11 on the face 8 and of the parts 14b and 15b, respectively on the flaps 13 and 12. Thanks to the automatic bottom 12, 13, 14a-14b and 15a-15b one then obtains a side folded flat and assembled as shown, from the front and rear, by Figures 2 and 3. In this flat position, the boxes according to the invention can be stored easily.

Lorsque l'on désire utiliser la boîte selon l'invention, on prend un flanc replié et assemblé tel que montré par les figures 2 et 3 et on écarte l'une de l'autre les faces 1 et 2 par rotation autor des lignes de prépliage 5, 6, 7 et 10, de manière à obtenir une boîte de forme parallélépipédique ouverte à son extrémité supérieure. A ce moment le fond automatique se met en place et l'on peut disposer dans la boîte selon l'invention les objets à emballer et/ou à transporter. Lorsque ceux-ci sont mis en place, on obture l'ouverture de ladite boîte en rabattant le rabat 17 et en pressant l'un en direction de l'autre les bords supérieurs des faces 1 et 2.When it is desired to use the box according to the invention, take a folded and assembled side as shown in FIGS. 2 and 3 and move the sides 1 and 2 away from each other by autorotating the lines of pre-folding 5, 6, 7 and 10, so as to obtain a box of parallelepiped shape open at its upper end. At this time the automatic bottom is set up and the objects to be packaged and / or transported can be placed in the box according to the invention. When these are put in place, the opening of said box is closed by folding down the flap 17 and pressing one towards the other the upper edges of the faces 1 and 2.

De plus, la languette 31 est rabattue à travers les ouvertures 20 et 21 qui se trouvent alors en correspondance.In addition, the tongue 31 is folded down through the openings 20 and 21 which are then in correspondence.

La boîte selon l'invention peut alors présenter la forme généraie montrée sur la figure 4, les ensembles de lignes de prépliage 4a, 4b, 4c, et 9a, 9b, 9c permettant aux faces 3 et 8 de former des soufflets se rétrécissant du fond vers l'ouverture de la boïte. Dans ce cas, les lignes de pliage 4d, 4e, 4f, 4g et 9d, 9e, 9f, 9g restent dans le plan des parties des soufflets dans lesquelles ils sont pratiqués, et la boîte selon l'invention est telle que sa section va en se rétrécissant de façon continue depuis le fond jusqu'à la partie supérieure de ladite boîte. En revanche, il est également possible de faire en sorte que les lignes de pliage 4f, 4g et 9f, 9g forment des plis convexes dans les parties correspondantes des soufflets, alors que les lignes de pliage 4d, 4e et 9d, 9e forment des plis concaves dans lesdites parties des soufflets. Dans ce cas, la boîte selon l'invention présente l'allure représentée sur la figure 5, la section de la boîte étant rectangulaire et constante entre son fond et les ensembles de firmes de pliage 4d, 4e, 4f, 4g et 9d, 9e, 9f, 9g, et allant en se rétrécissant de façon continue entre lesdits ensembles de lignes et la partie supérieure de ladite boîte. Ainsi, à volonté et en fonction de la forme et de l'encombrement des objets contenus dans ladite boîte, il est possible de choisir la forme extérieure de celle-ci, pour lui donner soit la forme représentée sur la figure 4, soit la forme représentée sur la figure 5.The box according to the invention can then have the general form shown in FIG. 4, the sets of pre-folding lines 4a, 4b, 4c, and 9a, 9b, 9c allowing the faces 3 and 8 to form bellows narrowing from the bottom towards the opening of the box. In this case, the fold lines 4d, 4e, 4f, 4g and 9d, 9e, 9f, 9g remain in the plane of the parts of the bellows in which they are made, and the box according to the invention is such that its section goes shrinking continuously from the bottom to the top of said box. On the other hand, it is also possible to make the fold lines 4f, 4g and 9f, 9g form convex folds in the corresponding parts of the bellows, while the fold lines 4d, 4e and 9d, 9e form folds concave in said parts of the bellows. In this case, the box according to the invention has the shape shown in FIG. 5, the section of the box being rectangular and constant between its bottom and the sets of folding firms 4d, 4e, 4f, 4g and 9d, 9e , 9f, 9g, and continuously narrowing between said sets of lines and the upper part of said box. Thus, at will and depending on the shape and size of the objects contained in said box, it is possible to choose the exterior shape of the latter, to give it either the shape shown in FIG. 4, or the shape shown in Figure 5.

Dans la variante de réalisation des figures 6 et 7, les bords latéraux 33 et 34 de la languette 31 sont convergents vers l'extérieur. De plus, dans l'ouverture 20 est prévue une languette 23 articulée autor d'une ligne de prépliage inférieure 24 s'étendant sur la partie intermédiaire de ladite languette, parallèlement à la ligne de prépliage 16. De même, dans l'ouverture 21 est prévue une languette 25, articulée autor d'une ligne de prépliage inférieure 26 s'étendant sur la partie intermédiaire de ladite languette parallèlement à la ligne de prépliage 16. Les languettes 23 et 25 présentent des éléments 27 et 28 susceptibles de coopérer l'un avec l'autre pour verrouiller lesdites languettes en position repliée. Par ailleurs, les bords latéraux 29 et 30 de la partie supérieure de l'ouverture 21 sont obliques et convergent vers l'extérieur.In the alternative embodiment of FIGS. 6 and 7, the lateral edges 33 and 34 of the tongue 31 are converging towards the outside. In addition, in the opening 20 is provided a tongue 23 articulated autor of a lower pre-folding line 24 extending over the intermediate part of said tongue, parallel to the pre-folding line 16. Similarly, in the opening 21 is provided a tongue 25, articulated autor of a lower pre-folding line 26 extending over the intermediate part of said tongue parallel to the pre-folding line 16. The tongues 23 and 25 have elements 27 and 28 likely to cooperate with each other to lock said tabs in the folded position. Furthermore, the lateral edges 29 and 30 of the upper part of the opening 21 are oblique and converge towards the outside.

En position dépliée de la boîte (voir maintenant la figure 7) le rabat 17 est rabattu sur la face 2 par pliage autor des lignes de prépliage 18 et 19 et les ouvertures 20, 21 et 22 se trouvent en regard l'une de l'autre. On replie les languettes 23 et 25 l'une vers l'autre et l'on fait coopérer les moyens 27 et 28 pour les fixer l'un à l'autre. Ces languettes permettent donc d'obturer la boîte au niveau des ouvertures 20, 21 et 22.In the unfolded position of the box (now see FIG. 7) the flap 17 is folded down on the face 2 by automatic folding of the pre-folding lines 18 and 19 and the openings 20, 21 and 22 are located opposite one of the other. The tongues 23 and 25 are folded back towards each other and the means 27 and 28 are made to cooperate to fix them to one another. These tabs therefore make it possible to close the box at the openings 20, 21 and 22.

Par ailleurs, la languette 31 est repliée vers l'intérieur et vers le haut de manière que ses bords obliques 33 et 34 coopèrent respectivement avec les bords 29 et 30 de l'ouverture 21 pour assurer le verrouillage en position de ladite languette. Ce verrouillage assure également celui du rabat 17 sur la face 2.Furthermore, the tongue 31 is folded inwards and upwards so that its oblique edges 33 and 34 cooperate respectively with the edges 29 and 30 of the opening 21 to ensure the locking in position of said tongue. This locking also ensures that of the flap 17 on the face 2.

Ainsi, les ouvertures 20, 21 et 22 délimitent, dans les faces 1 et 2 et dans le rabat 17, une poignée susceptible de permettre la préhension à la main de la boîte. On remarquera que cette poignée est particulièrement confortable grâce à la languette rabattue 31, qui évite le contact de la main avec les bords supérieurs des ouvertures 20,21 et 22.Thus, the openings 20, 21 and 22 delimit, in the faces 1 and 2 and in the flap 17, a handle capable of allowing the hand to grip the box. It will be noted that this handle is particularly comfortable thanks to the folded tongue 31, which prevents hand contact with the upper edges of the openings 20, 21 and 22.

Dans la variante de réalisation de la figure 8, des découpes 35, 36, par exemple circulaires, sont prévues à cheval sur les lignes de prépliagP 4c, et 9c de façon à former des encoches dans lesquelles viennent s'encliqueter élastiquement les bords latéraux 33 et 34 de la languette 31, lorsque celle-ci est rabattue vers l'intérieur et vers le haut. Le verrouillage de cette languette 31 et donc celui du rabat 17, est donc dans ce cas obtenu par la coopération des bords latéraux 33 et 34 avec les encoches 35 et 36 (voir la figure 9). Bien entendu, il est alors nécessaire que la largeur de la languette 31 (du bord 33 au bord 34) soit plus grande que la distance séparant, en position d'utilisation de la boîte selon l'invention, le pli 4c du pli 9c.In the alternative embodiment of FIG. 8, cutouts 35, 36, for example circular, are provided straddling the pre-folding lines P 4c, and 9c so as to form notches in which the lateral edges are snapped into place 33 and 34 of the tongue 31, when the latter is folded inwards and upwards. The locking of this tongue 31 and therefore that of the flap 17, is therefore in this case obtained by the cooperation of the lateral edges 33 and 34 with the notches 35 and 36 (see FIG. 9). Of course, it is then necessary for the width of the tongue 31 (from the edge 33 to the edge 34) to be greater than the distance separating, in the position of use of the box according to the invention, the fold 4c from the fold 9c.
