Description

DESCRIPTION DESCRIPTION
TITRE : Conteneur pliable notamment pour le transport de fruits et légumes TITLE: Collapsible container especially for the transport of fruits and vegetables
Domaine technique de l’invention Technical field of the invention
L’invention concerne un conteneur pliable pour le transport de produits et plus particulièrement pour le transport de fruits et légumes, spécialement en matière plastique, constitué d'un fond de conteneur et de quatre parois latérales articulées à celui-ci. The invention relates to a collapsible container for the transport of products and more particularly for the transport of fruit and vegetables, especially in plastic material, consisting of a container bottom and four side walls hinged thereto.
Arrière-plan technologique de l’invention Technological background of the invention
On connaît bien des conteneurs de ce type, dont les parois latérales sont reliées au fond du conteneur soit par des charnières articulées et espacées, disposées sur la circonférence du fond, soit par des charnières en film moulé d'un seul tenant sous la forme d’une ligne de pliage. Les parois latérales peuvent ainsi être rabattues vers l'intérieur sur le fond après utilisation du conteneur, ce qui réduit l'espace nécessaire pour le transport de retour et le stockage des conteneurs vides. Les charnières sous forme de lignes de pliage présentent l’avantage d'être faciles à nettoyer et de fabrication facile. Containers of this type are well known, the side walls of which are connected to the bottom of the container either by articulated and spaced hinges, arranged on the circumference of the bottom, or by hinges in molded film in one piece in the form of a fold line. The side walls can thus be folded inwards on the bottom after use of the container, which reduces the space required for the return transport and storage of empty containers. Hinges in the form of folding lines have the advantage of being easy to clean and easy to manufacture.
De tels conteneurs sont décrits notamment dans les demandes de brevet WO 96/11144, EP1060999, EP1480887, EP2419344, EP2477902 et EP2548809. Such containers are described in particular in patent applications WO 96/11144, EP1060999, EP1480887, EP2419344, EP2477902 and EP2548809.
Le document WO96/11144 décrit un récipient repliable en matière plastique comportant une base et plusieurs parois qui sont chacune reliées à la base via au moins une articulation à charnière de telle sorte qu’on peut les faire basculer jusque dans une position dans laquelle elles sont au moins approximativement parallèles à ladite base, l’articulation à charnière comprenant d’une part un logement d’articulation à charnière comprenant au moins une section d’entrée par poussée et une section terminale se suivant l’une l’autre dans une direction d’entrée par poussée et étant séparées par un espace libre, ainsi qu’un passage qui traverse totalement la section d’entrée par poussée et au moins une partie de la section terminale, une cheville de charnière étant montée en rotation dans le passage dans une position de chevauchement avec la section terminale et avec la section d’entrée par poussée. Le récipient comporte, par ailleurs, un mécanisme de verrouillage des parois latérales dudit récipient en plastique pliable. Chaque paroi latérale, qui se replie d'abord vers l'intérieur, comporte une rallonge de crochet à chacun de ses angles supérieurs. La rallonge de crochet comporte une toile de capture qui pointe en direction de la paroi latérale adjacente et qui est apte à coopérer avec un verrou muni d’une poignée de déverrouillage à chacune des extrémités du panneau latéral.

Each side wall, which folds inward first, has a hook extension at each of its top corners. The hook extension comprises a capture web which points in the direction of the adjacent side wall and which is capable of cooperating with a lock provided with a release handle at each of the ends of the side panel.
Le document EP1060999 décrit un conteneur, en particulier pour le transport de fruits et légumes, comportant un fond et quatre parois latérales qui peuvent être rabattues sur le fond. Les parois latérales sont reliées au fond par des charnières qui sont conçues comme des éléments de connexion enfichables, de sorte que les parois latérales peuvent être enfichées avec leurs charnières disposées sur leur bord inférieur dans les ouvertures correspondantes du fond du conteneur et verrouillées dans celles-ci par des éléments de verrouillage. Document EP1060999 describes a container, in particular for transporting fruit and vegetables, comprising a bottom and four side walls which can be folded down on the bottom. The side walls are connected to the bottom by hinges which are designed as plug-in connection elements, so that the side walls can be plugged with their hinges arranged on their lower edge into the corresponding openings of the bottom of the container and locked therein. ci by locking elements.
Le document EP1480887 décrit un récipient, notamment réutilisable, comportant des parois latérales repliables et un fond sur lequel lesdites parois latérales sont articulées. Ledit récipient comprend des moyens de fermeture par encliquetage comprenant un levier de pression qui peut être pressé vers l'intérieur et qui interagit avec un ergot de positionnement qui est configuré sur la paroi latérale adjacente, disposé en diagonale à travers celle-ci. The document EP1480887 describes a container, in particular reusable, comprising collapsible side walls and a bottom on which said side walls are hinged. Said container comprises snap closure means comprising a pressure lever which can be pressed inwards and which interacts with a positioning pin which is configured on the adjacent side wall, arranged diagonally therethrough.
Le document EP2419344 décrit une caisse pliable avec un fond et chaque fois deux parois extérieures rabattables par rapport au fond du côté longitudinal et du côté transversal, opposés par paire, chacune des parois extérieures du côté longitudinal présentant, à au moins une extrémité du côté transversal, une saillie s’étendant, à l’état replié vers le haut, en direction des parois latérales du côté transversal qui limite l’aptitude au rabattement vers l’extérieur des parois extérieures du côté transversal. Chacune des parois extérieures du côté transversal comporte un mécanisme de verrouillage à pré-tension de ressort disposé du côté extérieur de la paroi extérieure du côté transversal qui présente, à l’état rabattu vers le haut, un élément d’encliquetage déplaçable dans la direction verticale par rapport à la surface du fond. Le document EP2477902 décrit une caisse utilisable de manière flexible, comprenant un fond et quatre parois latérales opposées par paires qui s'étendent dans une direction verticale du fond vers le haut. Une des quatre parois latérales est configurée comme une paroi d'ouverture qui recouvre complètement une région de surface latérale quand elle est fermée et est mobile quand elle est ouverte, la paroi d'ouverture ne recouvrant qu'une partie de la région de surface latérale, de sorte que la paroi d'ouverture recouvre au moins en partie, quand elle est ouverte, une des parois latérales adjacentes ou le fond de la caisse. The document EP2419344 describes a collapsible box with a bottom and each time two folding outer walls with respect to the bottom of the longitudinal side and the transverse side, opposite in pairs, each of the outer walls of the longitudinal side having, at at least one end of the transverse side , a protrusion extending, in the folded state upwards, in the direction of the side walls of the transverse side which limits the outward folding ability of the outer walls of the transverse side. Each of the transverse side outer walls has a spring pre-tensioned locking mechanism disposed on the outer side of the transverse side outer wall which, in the folded-up state, has a latching element movable in the direction vertical to the bottom surface. EP2477902 discloses a flexibly usable crate comprising a bottom and four pairwise opposing side walls which extend in a vertical direction from the bottom upwards. One of the four side walls is configured as an opening wall which completely covers a side surface region when closed and is movable when open, the opening wall covering only part of the side surface region , so that the opening wall covers at least in part, when it is open, one of the adjacent side walls or the bottom of the body.
On connaît également le document EP2548809 qui décrit un récipient pliable comprenant une base, une première paire de parois opposées et une deuxième paire de parois opposées, la première paire de parois opposées et la deuxième paire de parois opposées définissant une ouverture dans le haut du récipient, dans lequel le récipient comprend en outre au moins un élément d'empilage qui, lorsque le récipient est érigé, est mobile entre une position d'empilage dans laquelle l'élément d'empilage est positionné pour supporter la base d'un autre conteneur sur celui-ci et une position de remplissage dans laquelle l'élément d'empilage est sensiblement retiré de l'ouverture dans le haut du conteneur, et dans lequel le conteneur comprend en outre au moins un élément de verrouillage (20) pour fixer le au moins un élément d'empilage au conteneur. Document EP2548809 is also known, which describes a collapsible container comprising a base, a first pair of opposed walls and a second pair of opposed walls, the first pair of opposed walls and the second pair of opposed walls defining an opening in the top of the container , wherein the container further comprises at least one stacking member which, when the container is erected, is movable between a stacking position in which the stacking member is positioned to support the base of another container thereon and a filling position in which the stacking element is substantially withdrawn from the opening in the top of the container, and in which the container further comprises at least one locking element (20) for securing the at least one stacking element to the container.
Tous ces conteneurs pliables pour le transport de fruits ou légumes ou similaires présentent l’inconvénient d’être lourds, chaque paroi latérale, longitudinale et de fond étant réalisée dans du plastique injecté, et d’être onéreux à produire. Par ailleurs, ces conteneurs présentent également l’inconvénient de procurer un encombrement trop important lorsqu’ils sont empilés en position repliée. All these collapsible containers for transporting fruit or vegetables or the like have the drawback of being heavy, each side, longitudinal and bottom wall being made of injected plastic, and of being expensive to produce. Furthermore, these containers also have the disadvantage of providing too much space when they are stacked in the folded position.
Divulgation de l’invention Disclosure of Invention
L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant un conteneur repliable comprenant une paroi de fond, deux parois latérales opposées articulées à la paroi de fond, deux parois longitudinales opposées articulées à ladite paroi de fond, lesdites parois latérales et longitudinales définissant une ouverture dans la partie supérieure du conteneur et étant rabattables vers la paroi de fond, caractérisé en ce qu’il est constitué d’une découpe dans un matériau en feuille rigide comprenant un volet central de forme sensiblement rectangulaire, deux volets latéraux formant les parois latérales du conteneur, lesdits volets latéraux étant reliés au volet central par une première ligne de pliage respectivement, et lesdits volets latéraux comportant respectivement deux rabats latéraux s’étendant de part et d’autre de chaque volet latéral et étant relié audit volet latéral par une seconde ligne de pliage respectivement, deux volets longitudinaux formant les parois longitudinales, lesdits volets longitudinaux étant reliés au volet central par une troisième ligne de pliage respectivement et comportant des moyens de fixation aptes à coopérer avec des moyens de fixation complémentaires solidaires des rabats latéraux. One of the aims of the invention is therefore to remedy these drawbacks by proposing a collapsible container comprising a bottom wall, two opposite side walls hinged to the bottom wall, two opposite longitudinal walls hinged to said bottom wall, said lateral and longitudinal walls defining an opening in the upper part of the container and being hinged towards the bottom wall, characterized in that it consists of a blank in a rigid sheet material comprising a central flap of substantially rectangular shape, two side flaps forming the side walls of the container, said side flaps being connected to the central flap by a first fold line respectively, and said side flaps comprising respectively two side flaps extending on either side of each side flap and being connected to said side flap by a second fold line respectively, two longitudinal flaps forming the longitudinal walls, said longitudinal flaps being connected to the central flap by a third fold line respectively and comprising fixing means capable of cooperating with complementary fixing means secured to the side flaps.
Selon une caractéristique de l’invention, la feuille rigide est en plastique. According to one characteristic of the invention, the rigid sheet is made of plastic.
Selon une caractéristique de l'invention, la feuille rigide est un moulage sensiblement plan. According to one characteristic of the invention, the rigid sheet is a substantially planar molding.
Ainsi, le conteneur est facile à fabriquer car il est formé par une unique découpe, c’est-à-dire d’un seul tenant sensiblement plan. Thus, the container is easy to manufacture because it is formed by a single cutout, that is to say in a single substantially flat piece.
Les lignes de pliage sont formées par un film moulé d’un seul tenant avec la découpe. Ainsi, les lignes de pliage sont formées dans le même matériaux que la découpe. Les lignes de pliage peuvent être pliées à 90° ou à 180°. The fold lines are formed by a film molded in one piece with the cutout. Thus, the fold lines are formed in the same material as the cutout. Bend lines can be bent 90° or 180°.
Lorsque le conteneur est en position d’utilisation, les rabats latéraux viennent en contact avec les volets longitudinaux. Les rabats latéraux s’étendent alors dans le plan dans lequel s’étendent les volets longitudinaux. Les rabats latéraux sont donc dans un plan perpendiculaire au plan dans lequel s’étendent les volets latéraux. Les rabats latéraux permettent de maintenir le conteneur en position d’utilisation. When the container is in the position of use, the side flaps come into contact with the longitudinal flaps. The side flaps then extend in the plane in which the longitudinal flaps extend. The side flaps are therefore in a plane perpendicular to the plane in which the side flaps extend. The side flaps keep the container in position for use.
En position repliée, les volets longitudinaux sont repliés vers la paroi de fond de sorte que les volets longitudinaux s’étendent dans le même plan que la paroi de fond. In the folded position, the longitudinal flaps are folded towards the bottom wall so that the longitudinal flaps extend in the same plane as the bottom wall.
En position repliée, le conteneur présente une faible hauteur totale, comprise entre quatre et dix épaisseurs de la découpe, préférentiellement six. En effet, la hauteur totale est formée par au moins l’épaisseur du volet central, du volet latéral, du rabat latéral, et du volet longitudinal. In the folded position, the container has a low total height, between four and ten thicknesses of the blank, preferably six. Indeed, the total height is formed by at least the thickness of the central flap, the side flap, the side flap, and the longitudinal flap.
Selon une caractéristique de l'invention, chaque rabat latéral comporte à son extrémité distale une languette latérale reliée au rabat latéral par une quatrième ligne de pliage. La quatrième ligne de pliage forme un axe de rotation entre le rabat latéral et la languette latérale. Il existe donc un degré de liberté entre le rabat latéral et la languette latérale. De cette manière, il est possible de replier le rabat latéral sur la languette latérale en position repliée. According to one characteristic of the invention, each side flap has at its distal end a side tab connected to the side flap by a fourth fold line. The fourth fold line forms an axis of rotation between the side flap and the side tab. There is therefore a degree of freedom between the side flap and the side tab. In this way, it is possible to fold the side flap over the side tab in the folded position.
Selon une caractéristique de l'invention, la quatrième ligne de pliage forme un angle de 45° avec les deuxième et troisième lignes de pliage. According to a feature of the invention, the fourth fold line forms an angle of 45° with the second and third fold lines.
Ainsi, la mise en position repliée du conteneur est facilitée. Thus, placing the container in the folded position is facilitated.
Selon une caractéristique de l'invention, les moyens de fixation complémentaires sont solidaires des languettes latérales des rabats latéraux. According to one characteristic of the invention, the complementary fastening means are secured to the side tongues of the side flaps.
Ainsi, un passage entre une position repliée et un position d’utilisation est facilitée. En effet, la languette latérale est fixée au volet longitudinal et reste fixée au volet longitudinal lors d’une mise en position repliée. Thus, a passage between a folded position and a position of use is facilitated. Indeed, the side tongue is fixed to the longitudinal flap and remains fixed to the longitudinal flap when placed in the folded position.
Lors d’une ouverture du conteneur, c’est-à-dire lors du passage d’une position repliée à une position d’utilisation, un utilisateur tire sur chaque volet latéral qui entraine le rabat latéral puis la languette latérale et enfin le volet longitudinal par le jeu des différentes lignes de pliage. When opening the container, that is to say when passing from a folded position to a use position, a user pulls on each side flap which causes the side flap then the side tab and finally the flap longitudinal by the play of the different folding lines.
Selon une caractéristique de l'invention, les moyens de fixation complémentaires s’étendent depuis une face intérieure des rabats latéraux. According to a characteristic of the invention, the complementary fastening means extend from an inner face of the side flaps.
La face intérieure des volets, des rabats ou des languettes du conteneur sont les faces venant au contact du volet central en position repliée. The inner face of the flaps, flaps or tabs of the container are the faces coming into contact with the central flap in the folded position.
La face extérieure des volets, des rabats ou des languettes du conteneur sont les faces opposées aux faces venant au contact du volet central en position repliée. The outer face of the flaps, flaps or tabs of the container are the faces opposite the faces coming into contact with the central flap in the folded position.
Ainsi les rabats latéraux viennent se fixer sur une face extérieure, c’est-à-dire la face opposée à la face venant au contact du volet central en position repliée, des volets latéraux. Le volet latéral vient en contact avec le volet central en position repliée. Thus the side flaps are fixed on an outer face, that is to say the face opposite to the face coming into contact with the central flap in the folded position, of the side flaps. The side flap comes into contact with the central flap in the folded position.
Selon une caractéristique de l'invention, les moyens de fixation complémentaires s’étendent depuis une face extérieure des rabats latéraux. According to one characteristic of the invention, the complementary fastening means extend from an outer face of the side flaps.
Ainsi les rabats latéraux viennent se fixer sur une face intérieure, c’est-à-dire la face venant au contact du volet central en position repliée, des volets latéraux. Le volet latéral est espacé du volet central par le rabat latéral, en position repliée. Selon une caractéristique de l'invention, les moyens de fixation des volets longitudinaux consistent en des lumières oblongues et en ce que les moyens de fixation complémentaires des rabats latéraux consistent en deux pattes diamétralement opposés s’étendant depuis l’une des faces desdits rabats latéraux et dont les extrémités sont munies de crochets s’étendant vers l’extérieur, lesdits crochets étant aptes à coopérer par déformation plastique avec le bord intérieur des lumières oblongues. Thus the side flaps are fixed on an inner face, that is to say the face coming into contact with the central flap in the folded position, of the side flaps. The side flap is spaced from the central flap by the side flap, in the folded position. According to one characteristic of the invention, the means for fixing the longitudinal flaps consist of oblong openings and in that the complementary means for fixing the side flaps consist of two diametrically opposed lugs extending from one of the faces of said flaps side and whose ends are provided with hooks extending outwards, said hooks being able to cooperate by plastic deformation with the inner edge of the oblong slots.
Ainsi les pattes viennent se clipper dans les lumières oblongues. Thus the legs are clipped into the oblong slots.
Selon une caractéristique de l'invention, les moyens de fixation des volets longitudinaux consistent en des lumières munies d’un élément central et en ce que les moyens de fixation complémentaires des rabats latéraux consistent en deux ergots opposés s’étendant depuis l’une des faces desdits rabats latéraux. Ainsi les ergots viennent se clipper de part et d’autre de l’élément central de la lumière. According to one characteristic of the invention, the means for fixing the longitudinal flaps consist of openings provided with a central element and in that the complementary means for fixing the side flaps consist of two opposite lugs extending from one of the faces of said side flaps. Thus the lugs are clipped on either side of the central element of the light.
Selon une caractéristique de l'invention, les volets longitudinaux présentent une forme de trapèze isocèle, dont les côtés forment un angle de 45° avec les troisièmes lignes de pliage. According to one characteristic of the invention, the longitudinal flaps have the shape of an isosceles trapezium, the sides of which form an angle of 45° with the third folding lines.
Ainsi le rabat latéral vient compléter, en position d’utilisation, le volet longitudinal de manière à former une paroi longitudinale complète entre les deux parois latérales. La quatrième ligne de pliage vient au contact des côtés du volet longitudinal formant un angle de 45° et uniquement la languette latérale vient en surépaisseur sur le volet longitudinal de manière à rigidifier le conteneur en position d’utilisation. Thus the side flap completes, in the position of use, the longitudinal flap so as to form a complete longitudinal wall between the two side walls. The fourth fold line comes into contact with the sides of the longitudinal flap forming an angle of 45° and only the lateral tongue comes in extra thickness on the longitudinal flap so as to stiffen the container in the position of use.
Selon une caractéristique de l'invention, le trapèze isocèle a des côtés qui forment un angle de 45° avec les troisièmes lignes de pliage. According to a characteristic of the invention, the isosceles trapezium has sides which form an angle of 45° with the third folding lines.
Selon une caractéristique de l'invention, les volets latéraux comportent respectivement au moins un premier évidement le long de son bord proximal avec le volet central. According to a characteristic of the invention, the side flaps respectively comprise at least a first recess along its proximal edge with the central flap.
Ainsi, l’évidement forme d’une part une poignée de préhension et d’autre part permet de libérer de l’espace pour un plot de gerbage. Thus, the recess forms on the one hand a gripping handle and on the other hand frees up space for a stacking block.
Ainsi il est facile de déplacer manuellement le conteneur. Thus it is easy to manually move the container.
Selon une caractéristique de l'invention, les volets latéraux comportent respectivement un second évidement le long de son bord distal, lesdits second évidement formant une zone de dégagement. According to one characteristic of the invention, the side flaps respectively comprise a second recess along its distal edge, said second recess forming a clearance zone.
Ainsi il est possible de limiter l’utilisation de matière lors de la fabrication du conteneur et de permettre que des objets positionnés dans le conteneur sortent en partie de celui-ci par le second évidement. Thus, it is possible to limit the use of material during the manufacture of the container and to allow objects positioned in the container to partly come out of it through the second recess.
Selon une caractéristique de l'invention, le volet central comporte un plot de gerbage s’étendant depuis la face intérieure du volet central et muni d’un évidement depuis la face extérieure du volet central, ledit évidement du plot étant apte à recevoir l’extrémité supérieure d’un plot de gerbage d’un second conteneur empilé sous le premier conteneur. According to one characteristic of the invention, the central flap comprises a stacking stud extending from the inner face of the central flap and provided with a recess from the outer face of the central flap, said recess of the stud being adapted to receive the upper end of a stacking stud for a second container stacked under the first container.
Ainsi, l’empilement des conteneurs est facilité. Thus, the stacking of containers is facilitated.
Selon une caractéristique de l'invention, le volet central comprend des lumières, s’étendant au droit des lumières des volets longitudinaux lorsque ces derniers sont repliés sur le volet central. According to a characteristic of the invention, the central pane comprises slots, extending to the right of the slots of the longitudinal panes when the latter are folded over the central pane.
Ainsi, les lumières du volet central permettent le passage des pattes et des crochets des rabats latéraux ou des ergots lorsque les volets longitudinaux et latéraux sont repliés sur la volet central. Thus, the openings of the central flap allow the passage of the tabs and the hooks of the side flaps or the lugs when the longitudinal and lateral flaps are folded over the central flap.
Selon une caractéristique de l'invention, les bords distaux des volets latéraux comprennent des crochets s’étendant depuis la face intérieure desdits volets latéraux et aptes à coopérer avec des lumières pratiquées dans le volet central. Ainsi, il est possible d’assurer la fixation des volets latéraux sur le volet central lorsque le conteneur est en position repliée. According to a characteristic of the invention, the distal edges of the side flaps comprise hooks extending from the inner face of said side flaps and capable of cooperating with slots made in the central flap. Thus, it is possible to ensure the fixing of the side flaps on the central flap when the container is in the folded position.
Selon une caractéristique de l'invention, les volets longitudinaux et/ou les volets latéraux comprennent des nervures. According to one characteristic of the invention, the longitudinal flaps and/or the side flaps comprise ribs.
Ainsi il est possible de rigidifier les parois longitudinales et/ou latérales respectivement. Thus it is possible to stiffen the longitudinal and/or lateral walls respectively.
Selon une caractéristique de l'invention, au moins un volet latéral comprend au moins un crochet apte à maintenir le volet latéral contre le volet central et apte à maintenir un deuxième conteneur positionné sur ledit conteneur. According to one characteristic of the invention, at least one side flap comprises at least one hook able to hold the side flap against the central flap and able to hold a second container positioned on said container.
Le crochet a deux fonctions distinctes, d’une part il permet de maintenir le volet latéral contre le volet central en position repliée, et d’autre part, il permet de maintenir un deuxième conteneur positionné sur ledit premier conteneur en position d’utilisation. The hook has two distinct functions, on the one hand it keeps the side flap against the central flap in the folded position, and on the other hand, it keeps a second container positioned on said first container in the position of use.
Selon une caractéristique de l'invention, un bord distal d’au moins un rabat latéral comprend au moins une attache apte à coopérer avec une boucle positionnée sur un bord distal d’au moins une paroi longitudinale. According to one characteristic of the invention, a distal edge of at least one side flap comprises at least one fastener capable of cooperating with a loop positioned on a distal edge of at least one longitudinal wall.
De cette manière, en position d’utilisation, le rabat latéral est parfaitement maintenu contre la paroi longitudinale. In this way, in the position of use, the side flap is perfectly held against the longitudinal wall.
Selon une caractéristique de l'invention, la boucle comprend un évidement en son centre. According to one characteristic of the invention, the loop comprises a recess in its center.
Ainsi, la boucle présente des caractéristiques de souplesse et de rigidité permettant une déformation de celle-ci adaptée à faciliter la coopération avec l’attache. Thus, the loop has characteristics of flexibility and rigidity allowing a deformation of the latter adapted to facilitate cooperation with the fastener.
Selon une caractéristique de l'invention, l’attache présente une forme de T. Vue en coupe, l’attache présente une forme de T. Ainsi, une première partie du T est destiné à coopérer avec la boucle tandis qu’une deuxième partie du T permet de maintenir un deuxième conteneur positionné sur ledit premier conteneur en position d’utilisation. According to one characteristic of the invention, the attachment has a T shape. Seen in section, the fastener has a T shape. Thus, a first part of the T is intended to cooperate with the loop while a second part of the T makes it possible to maintain a second container positioned on said first container in the position of use.

En référence aux figures 1 et 2, le conteneur suivant l’invention comprend une paroi de fond 1 , deux parois latérales 2 opposées articulées à la paroi de fond 1 , deux parois longitudinales 3 opposées articulées à ladite paroi de fond 1 , lesdites parois latérales 2 et longitudinales 3 définissant une ouverture 4 dans la partie supérieure du conteneur et étant rabattables vers la paroi de fond 1 , comme il sera détaillé plus loin. Referring to Figures 1 and 2, the container according to the invention comprises a bottom wall 1, two opposite side walls 2 hinged to the bottom wall 1, two opposite longitudinal walls 3 hinged to said bottom wall 1, said side walls 2 and longitudinal 3 defining an opening 4 in the upper part of the container and being foldable towards the bottom wall 1, as will be detailed below.
Ledit conteneur est constitué d’une découpe 5 obtenue dans un matériau en feuille plastique rigide comprenant un volet dit central 6 de forme sensiblement rectangulaire, formant la paroi de fond 1 , deux volets latéraux 7 formant les parois latérales 2 du conteneur, lesdits volets latéraux 7 étant reliés au volet central 6 par une première ligne de pliage 8 respectivement, et lesdits volets latéraux 7 comportant respectivement deux rabats latéraux 9 s’étendant de part et d’autre de chaque volet latéral 7 et étant relié audit volet latéral 7 par une seconde ligne de pliage 10 respectivement, deux volets longitudinaux 11 formant les parois longitudinales 3, lesdits volets longitudinaux 11 étant reliés au volet central 6 par une troisième ligne de pliage 12 respectivement et comportant des moyens de fixation 13 aptes à coopérer avec des moyens de fixation complémentaires 14 solidaires des rabats latéraux 9. On observera que la découpe 5 pourra être obtenu dans tout matériau plastique ou composite rigide bien connu de l’homme du métier. Said container consists of a cutout 5 obtained in a rigid plastic sheet material comprising a so-called central flap 6 of substantially rectangular shape, forming the bottom wall 1, two side flaps 7 forming the side walls 2 of the container, said side flaps 7 being connected to the central flap 6 by a first folding line 8 respectively, and said flaps 7 respectively comprising two side flaps 9 extending on either side of each side flap 7 and being connected to said side flap 7 by a second fold line 10 respectively, two longitudinal flaps 11 forming the longitudinal walls 3, said flaps longitudinal 11 being connected to the central flap 6 by a third fold line 12 respectively and comprising fixing means 13 capable of cooperating with complementary fixing means 14 integral with the side flaps 9. It will be observed that the cutout 5 can be obtained in any rigid plastic or composite material well known to those skilled in the art.
Chaque rabat latéral 9 comporte à son extrémité distale une languette latérale 15 relié au rabat latéral 9 par une quatrième ligne de pliage 16 formant un angle de 45° avec les deuxième 10 et troisième 12 lignes de pliage. Par ailleurs, les moyens de fixation complémentaires 14 sont solidaires des languettes latérales 15 des rabats latéraux 9. En référence aux figures 1 ,2 et 7, lesdits moyens de fixation complémentaires 14 des rabats latéraux 9 consistent en deux pattes 17 diamétralement opposés s’étendant depuis l’une des faces desdits rabats latéraux 9, en l’espèce la face dite intérieure des rabats latéraux 9, et dont les extrémités sont munies de crochets 18 s’étendant vers l’extérieur, lesdits crochets 18 étant aptes à coopérer par déformation plastique avec le bord intérieur des moyens de fixation 13 des volets longitudinaux 11 qui consistent en des lumières oblongues 19. Each side flap 9 has at its distal end a side tab 15 connected to the side flap 9 by a fourth fold line 16 forming an angle of 45° with the second 10 and third 12 fold lines. Furthermore, the complementary fixing means 14 are secured to the side tabs 15 of the side flaps 9. With reference to Figures 1, 2 and 7, said complementary fixing means 14 of the side flaps 9 consist of two diametrically opposed tabs 17 extending from one of the faces of said side flaps 9, in this case the so-called inner face of the side flaps 9, and whose ends are provided with hooks 18 extending outwards, said hooks 18 being capable of cooperating by deformation plastic with the inner edge of the fastening means 13 of the longitudinal flaps 11 which consist of oblong slots 19.
Il est bien évident que les lumières oblongues 19 pourront être substituées par des lumières circulaires sans pour autant sortir du cadre de l’invention. It is obvious that the oblong slots 19 could be substituted by circular slots without departing from the scope of the invention.
Par ailleurs, dans cet exemple particulier de réalisation, le grand axe des lumières oblongues 19 forme un angle avec les troisièmes lignes de pliage 12 compris entre 30 et 40°. De plus, les volets longitudinaux 11 présentent une forme de trapèze isocèle dont les côtés forment un angle de 45° avec les troisièmes lignes de pliage 12. Furthermore, in this particular embodiment, the major axis of the oblong slots 19 forms an angle with the third fold lines 12 of between 30 and 40°. In addition, the longitudinal flaps 11 have the shape of an isosceles trapezium whose sides form an angle of 45° with the third folding lines 12.
De manière avantageuse, les volets latéraux 7 comportent respectivement un premier évidement 20 le long de son bord proximal avec le volet central 6, lesdits premiers évidements 20 formant une poignée de préhension. Chaque volet latéral 7 comporte également un second évidement 21 le long de son bord distal, lesdits seconds évidements 21 formant une zone de dégagement. Advantageously, the side flaps 7 respectively comprise a first recess 20 along its proximal edge with the central flap 6, said first recesses 20 forming a grip handle. Each pane side 7 also includes a second recess 21 along its distal edge, said second recesses 21 forming a clearance zone.
De plus, le volet central 6 comporte le long des premières lignes de pliage 8, dans la partie médiane, respectivement un plot dit de gerbage 22 en forme général de prisme et s’étendant depuis la face intérieure du volet central 6 et muni d’un évidement 23 depuis la face extérieure du volet central 6, ledit évidement 23 du plot de gerbage 22 étant apte à recevoir l’extrémité supérieure d’un plot de gerbage 22 d’un second conteneur empilé sous le premier conteneur comme on peut le voir sur la figure 10. In addition, the central flap 6 comprises along the first folding lines 8, in the middle part, respectively a so-called stacking stud 22 in the general shape of a prism and extending from the inner face of the central flap 6 and provided with a recess 23 from the outer face of the central flap 6, said recess 23 of the stacking block 22 being capable of receiving the upper end of a stacking block 22 of a second container stacked under the first container as can be seen in Figure 10.
De manière avantageuse, afin de limiter la hauteur du conteneur en position repliée, le volet central 6 comprend des secondes lumières oblongues 24, s’étendant au droit des lumières oblongues 19 des volets longitudinaux 11 lorsque ces derniers sont repliés sur le volet central 6, et de dimensions supérieures aux dimensions des lumières oblongues 19 des volets longitudinaux 11 afin de permettre le passage des pattes 17 et des crochets 18 des rabats latéraux 7 lorsque les volets longitudinaux 11 et latéraux 7 sont repliés sur le volet central 6. Advantageously, in order to limit the height of the container in the folded position, the central flap 6 comprises second oblong slots 24, extending to the right of the oblong slots 19 of the longitudinal flaps 11 when the latter are folded on the central flap 6, and of dimensions greater than the dimensions of the oblong slots 19 of the longitudinal flaps 11 in order to allow the passage of the tabs 17 and the hooks 18 of the side flaps 7 when the longitudinal flaps 11 and side flaps 7 are folded over the central flap 6.
Par ailleurs, afin de maintenir les volets latéraux 7 et les volets longitudinaux 11 contre le volet central 6 en position repliée, les bords distaux des volets latéraux 7 comprennent des crochets 25 s’étendant depuis la face intérieure desdits volets latéraux 7 et aptes à coopérer avec des lumières rectangulaires pratiquées dans le volet central 6 pour assurer la fixation des volets latéraux 7 sur le volet central 6 lorsque le conteneur est en position repliée. Furthermore, in order to maintain the side flaps 7 and the longitudinal flaps 11 against the central flap 6 in the folded position, the distal edges of the side flaps 7 comprise hooks 25 extending from the inner face of said side flaps 7 and capable of cooperating with rectangular openings made in the central flap 6 to ensure the fixing of the side flaps 7 on the central flap 6 when the container is in the folded position.
Accessoirement les volets longitudinaux 11 et les volets latéraux 7 comprennent des nervures 27 afin de rigidifier les parois longitudinales 11 et latérales 7 respectivement, lesdites nervures 27 formant des raidisseurs. Incidentally, the longitudinal flaps 11 and the side flaps 7 comprise ribs 27 in order to stiffen the longitudinal 11 and lateral walls 7 respectively, said ribs 27 forming stiffeners.
On expliquera maintenant le fonctionnement, et plus particulièrement l’assemblage, du conteneur suivant en référence aux figures 2 à 10. We will now explain the operation, and more particularly the assembly, of the following container with reference to Figures 2 to 10.
En référence aux figures 1 et 2, les pattes 17 et les crochets 18 des moyens de fixation complémentaires 14 des rabats latéraux 9 des volets latéraux 7 sont introduits dans les lumières oblongues 19 des moyens de fixation 13 des volets longitudinaux 11 jusqu’à ce que les crochets 18 coopèrent avec le bord intérieur, par déformation élastique, des lumières oblongues 19 (figure 7). Les volets latéraux 7 sont alors articulés aux volets longitudinaux 11 autour des lignes de pliage 16 formant ainsi un soufflet accordéon et permettant le déploiement depuis une position repliée jusqu’à une position dépliée (figures 1 et 6). With reference to Figures 1 and 2, the lugs 17 and the hooks 18 of the complementary fixing means 14 of the side flaps 9 of the side flaps 7 are introduced into the oblong slots 19 of the fastening means 13 of the longitudinal flaps 11 until the hooks 18 cooperate with the inner edge, by elastic deformation, of the oblong slots 19 (FIG. 7). The side flaps 7 are then hinged to the longitudinal flaps 11 around the folding lines 16 thus forming an accordion bellows and allowing deployment from a folded position to an unfolded position (FIGS. 1 and 6).
Les conteneurs dépliés peuvent alors aisément être gerbés comme on peut le voir sur la figure 8, et les conteneurs repliés, les conteneurs étant maintenus en position repliés grâce aux crochets 25 des volets latéraux coopérant avec les lumières rectangulaires pratiquées dans le volet central 6, peuvent également être gerbés comme on peut le voir sur la figure 10, les évidements 23 des plots de gerbage 22 recevant l’extrémité supérieure d’un plot de gerbage 22 d’un second conteneur empilé sur le premier conteneur. The unfolded containers can then easily be stacked as can be seen in Figure 8, and the folded containers, the containers being held in the folded position thanks to the hooks 25 of the side flaps cooperating with the rectangular openings made in the central flap 6, can also be stacked as can be seen in Figure 10, the recesses 23 of the stacking studs 22 receiving the upper end of a stacking stud 22 of a second container stacked on the first container.
Selon une variante d’exécution du conteneur suivant l’invention, en référence aux figures 11 à 14, le conteneur suivant l’invention comprend de la même manière que précédemment, une paroi de fond 1 , deux parois latérales 2 opposées articulées à la paroi de fond 1 , deux parois longitudinales 3 opposées articulées à ladite paroi de fond 1 , lesdites parois latérales 2 et longitudinales 3 définissant une ouverture 4 dans la partie supérieure du conteneur et étant rabattables vers la paroi de fond 1 . Ledit conteneur est constitué d’une découpe 5 obtenue dans un matériau en feuille plastique rigide comprenant un volet dit central 6 de forme sensiblement rectangulaire, formant la paroi de fond 1 , deux volets latéraux 7 formant les parois latérales 2 du conteneur, lesdits volets latéraux 7 étant reliés au volet central 6 par une première ligne de pliage 8 respectivement, et lesdits volets latéraux 7 comportant respectivement deux rabats latéraux 9 s’étendant de part et d’autre de chaque volet latéral 7 et étant relié audit volet latéral 7 par une seconde ligne de pliage 10 respectivement, deux volets longitudinaux 11 formant les parois longitudinales 3, lesdits volets longitudinaux 11 étant reliés au volet central 6 par une troisième ligne de pliage 12 respectivement et comportant des moyens de fixation 13 aptes à coopérer avec des moyens de fixation complémentaires 14 solidaires des rabats latéraux 7. Chaque rabat latéral 9 comporte à son extrémité distale une languette latérale 15 relié au rabat latéral 9 par une quatrième ligne de pliage 16 formant un angle de 45° avec les deuxième 10 et troisième 12 lignes de pliage. Par ailleurs, les moyens de fixation complémentaires 14 sont solidaires des languettes latérales 15 des rabats latéraux. Lesdits moyens de fixation complémentaires 14 des rabats latéraux 9 consistent en deux pattes 17 diamétralement opposés s’étendant depuis l’une des faces desdits rabats latéraux 9 et dont les extrémités sont munies de crochets 18 s’étendant vers l’extérieur, lesdits crochets 18 étant aptes à coopérer par déformation plastique avec le bord intérieur des moyens de fixation 13 des volets longitudinaux 11 qui consistent en des lumières 19. According to a variant embodiment of the container according to the invention, with reference to FIGS. 11 to 14, the container according to the invention comprises, in the same way as above, a bottom wall 1, two opposite side walls 2 hinged to the wall bottom 1, two opposite longitudinal walls 3 hinged to said bottom wall 1, said side walls 2 and longitudinal walls 3 defining an opening 4 in the upper part of the container and being hinged towards the bottom wall 1 . Said container consists of a cutout 5 obtained in a rigid plastic sheet material comprising a so-called central flap 6 of substantially rectangular shape, forming the bottom wall 1, two side flaps 7 forming the side walls 2 of the container, said side flaps 7 being connected to the central flap 6 by a first fold line 8 respectively, and said side flaps 7 respectively comprising two side flaps 9 extending on either side of each side flap 7 and being connected to said side flap 7 by a second fold line 10 respectively, two longitudinal flaps 11 forming the longitudinal walls 3, said longitudinal flaps 11 being connected to the central flap 6 by a third fold line 12 respectively and comprising fixing means 13 capable of cooperating with fixing means complementary 14 attached to the side flaps 7. Each side flap 9 has at its distal end a side tab 15 connected to the side flap 9 by a fourth fold line 16 forming an angle of 45° with the second 10 and third 12 fold lines. Furthermore, the complementary fastening means 14 are secured to the side tabs 15 of the side flaps. Said complementary fixing means 14 of the side flaps 9 consist of two diametrically opposite tabs 17 extending from one of the faces of said side flaps 9 and whose ends are provided with hooks 18 extending outwards, said hooks 18 being able to cooperate by plastic deformation with the inner edge of the fixing means 13 of the longitudinal flaps 11 which consist of slots 19.
Cette variante d’exécution se distingue de celle précédemment décrite par le fait que les pattes 17 s’étendent depuis la face extérieure des rabats latéraux 9, et non depuis la face intérieure des rabats latéraux 9, et que les lumières 19 présentent une forme circulaire et non oblongue. This alternative embodiment differs from that previously described in that the tabs 17 extend from the outer face of the side flaps 9, and not from the inner face of the side flaps 9, and that the slots 19 have a circular shape. and not oblong.
Selon cette construction les volets longitudinaux 11 sont repliés vers la paroi de fond 1 vers l’extérieur du conteneur de sorte que, en position repliée, les volets longitudinaux s’étendent dans le même plan que la paroi de fond de chaque côté de cette dernière et non au-dessus de la paroi de fond comme dans la variante d’exécution précédente. According to this construction, the longitudinal flaps 11 are folded towards the bottom wall 1 towards the outside of the container so that, in the folded position, the longitudinal flaps extend in the same plane as the bottom wall on each side of the latter. and not above the bottom wall as in the previous variant.
Selon une seconde variante d’exécution du conteneur suivant l’invention, en référence aux figures 15 et 16, le conteneur suivant l’invention comporte toutes les caractéristiques du conteneur décrit en référence aux figures 1 à 10 ainsi que deux couvercles additionnels 30 articulés le long des bords distaux des volets latéraux 7 du conteneur. According to a second alternative embodiment of the container according to the invention, with reference to FIGS. 15 and 16, the container according to the invention comprises all the characteristics of the container described with reference to FIGS. along the distal edges of the side flaps 7 of the container.
Selon une troisième variante d’exécution du conteneur suivant l’invention, en référence aux figures 17 à 18, le conteneur suivant l’invention comporte toutes les caractéristiques du conteneur décrit en référence aux figures 1 à 10. According to a third alternative embodiment of the container according to the invention, with reference to Figures 17 to 18, the container according to the invention comprises all the characteristics of the container described with reference to Figures 1 to 10.
Cette variante d’exécution se distingue de celle précédemment décrite par le fait que les moyens de fixations 13’ sont aptes à coopérer avec des moyens de fixation complémentaires 14’. Lesdits moyens de fixation complémentaires 14’ des rabats latéraux 9 consistent en deux ergots opposés s’étendant depuis la face intérieure des rabats latéraux 9. Les ergots sont aptes à coopérer par déformation plastique avec les moyens de fixation 13’ des volets longitudinaux 11 qui consistent en des lumières sensiblement rectangulaires munies d’un élément central. Les ergots sont introduits de part et d’autre de l’élément central des moyens de fixation 13’. This alternative embodiment differs from that previously described in that the fixing means 13' are capable of cooperating with complementary fixing means 14'. Said complementary fastening means 14' of the side flaps 9 consist of two opposite lugs extending from the inner face of the side flaps 9. The lugs are capable of cooperating by plastic deformation with the fixing means 13' of the longitudinal flaps 11 which consist of substantially rectangular slots provided with a central element. The lugs are introduced on either side of the central element of the fixing means 13'.
Les crochets 25 permettent également de maintenir un deuxième conteneur positionné sur ledit premier conteneur en position d’utilisation comme on peut le voir à la figure 20. Dans ce cas, le crochet 25 vient coopérer avec la paroi latérale 2 du deuxième conteneur grâce à un évidement ménagé entre la paroi de fond 1 et la paroi latérale 2 du deuxième conteneur. The hooks 25 also make it possible to maintain a second container positioned on said first container in the position of use as can be seen in FIG. 20. In this case, the hook 25 cooperates with the side wall 2 of the second container thanks to a recess made between the bottom wall 1 and the side wall 2 of the second container.
Un bord distal d’un rabat latéral 9 comprend également une attache 100 ayant une forme de T qui permet d’une part de coopérer avec une boucle 101 positionnée sur un bord distal d’une paroi longitudinale 3 de sorte à maintenir le rabat latéral 9 contre la paroi longitudinale 3 en position d’utilisation, et d’autre part de maintenir un deuxième conteneur positionné sur ledit premier conteneur en position d’utilisation comme on peut le voir à la figure 20. Dans ce cas, le l’attache 100 vient coopérer avec la paroi longitudinale 3 du deuxième conteneur grâce à un évidement ménagé entre la paroi de fond 1 et la paroi longitudinale 3 du deuxième conteneur. A distal edge of a side flap 9 also comprises a fastener 100 having a T shape which allows on the one hand to cooperate with a loop 101 positioned on a distal edge of a longitudinal wall 3 so as to hold the side flap 9 against the longitudinal wall 3 in the use position, and secondly to maintain a second container positioned on said first container in the use position as can be seen in Figure 20. In this case, the fastener 100 cooperates with the longitudinal wall 3 of the second container through a recess formed between the bottom wall 1 and the longitudinal wall 3 of the second container.
Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières en aucun cas limitatives quant aux domaines d'application de l'invention. Finally, it is quite obvious that the examples which have just been given are only particular illustrations in no way limiting as to the fields of application of the invention.
