Les plateaux de ce type vent en general realises a partir d'un flan unique en carton, carton ondule ou materiau en feuil le analog ue, de forme generale rectangulai re, et dont la tenue mecanique, apres sa mise en volume, ne fait appel a aucun moyen de fixation du type Cardboard tray obtained by folding a pre-cut and precut blank The present invention is in the field of trays intended to transport, protect, store, group or enhance manufactured products such as furniture elements, mechanical parts , electronic components or agricultural products such as fruits and vegetables (peaches, apples, etc ...). The trays of this type are generally produced from a single blank of cardboard, corrugated cardboard or sheet material of the analogous type, generally rectangular in shape, and the mechanical strength of which, after being set in volume, does not require has no fixing means of the type

L'invention concerne plus particulierement un tel plateau, et un procede pour The invention relates more particularly to such a tray, and a method for

Ce type de plateau, dans sa forme de realisation la plus simple, comporte generalement un fond de forme rectangulaire prolonge sur sa peripherie par quatre panneaux lateraux qui vent dresses perpendiculairement audit fond pour This type of tray, in its simplest embodiment, generally includes a rectangular bottom extended on its periphery by four side panels which wind perpendicular to said bottom to

Pour conserver sa forme deployee et sa tenue mecanique sans utiliser de moyens de fixation externes, chaque panneau est. par exemple, muni a chacune de ses extremites laterales d'une languette venant, au cours de la mise en volume du conditionnement, cooperer avec l'extremite du panneau contigu specifiquement configuree a cet effet, soit un systeme classique a tenons To keep its deployed shape and its mechanical behavior without using external fixing means, each panel is. for example, provided at each of its lateral ends with a tongue which, during the packaging of the packaging, cooperates with the end of the adjoining panel specifically configured for this purpose, ie a conventional tenon system

Pour des raisons de place et pour faciliter leur transport, les plateaux vent generalement livres a plat aux industrials, agriculteurs ou autres utilisateurs, ces derniers devant realiser eux-memes le montage tridimensionnel des plateaux sur leur site d'utilisation. Cette derriere operation, meme avec des modeles de plateau aussi simples que ceux mentionnes precedemment, s'avere souvent relativement longue, voire fastidieuse. De plus, les parties contribuant a 3 0 I'assemblage du plateau, comme les languettes precitees, constituent typiquement des zones mecaniquement plus falbles qui peuvent facilement se deteriorer lors de leur mise en contact. Enfin, la tenue mecanique des plateaux For reasons of space and to facilitate their transport, the trays are generally delivered flat to industrialists, farmers or other users, the latter having to carry out themselves the three-dimensional mounting of the trays on their site of use. This rear operation, even with tray models as simple as those mentioned above, often turns out to be relatively long, even tedious. In addition, the parts contributing to the assembly of the plate, like the abovementioned tongues, typically constitute mechanically more falble zones which can easily deteriorate when brought into contact. Finally, the mechanical behavior of the trays

Le but de ['invention est de proposer une solution technique apte a pallier 3 S les inconvenients mentionnes ci-dessus. L'invention vise notamment a l'obtention d'un plateau dont la mise en volume a partir du flan unique a plat peut se faire plus facilement et plus rapidement par rapport aux plateaux de l'art anterieur, dont on puisse en plus modifier l'inclinaison relative de deux parois The object of the invention is to propose a technical solution capable of overcoming 3 S the drawbacks mentioned above. The invention aims in particular to obtain a tray whose volume setting from the single flat blank can be done more easily and more quickly compared to the trays of the prior art, which can be further modified the relative inclination of two walls

A cet effet, le plateau de ['invention, egalement realise a partir d'un flan unique en carton, carton ondule ou materiau en feuille analogue, se caracterise S principalement en ce que ledit flan comprend, articules au dit fond, d'une part, prolongeant les deux cotes paralleles longitudinaux de ce dernier, suivant deux To this end, the tray of the invention, also produced from a single blank of cardboard, corrugated cardboard or similar sheet material, is characterized mainly in that said blank comprises, articulated to said bottom, of a part, extending the two longitudinal parallel dimensions of the latter, following two

angle de (90 +a) avec la ligne de rainage inverse contigue. angle of (90 + a) with the contiguous reverse crease line.
En outre, deux volets decoupes dans ledit fond vent articules respectivement autour des deux lignes de rainage inverses pour venir se 2s redresser au-dessus audit fond en contact avec la face interieure de deux panneaux de liaison replies transversalement d'un meme cote audit fond, qui comporte au surplus deux ouvertures respectivement obtenues au moins en In addition, two cut-out flaps in the said wind bottom hinged respectively around the two reverse creasing lines to come up and rise up above said bottom in contact with the inner face of two connecting panels folded transversely on the same side to said bottom, which also has two openings respectively obtained at least in

Dans le cas de volets trapezordaux, cette configuration est indispensable pour permettre le passage des panneaux transversaux a travers les ouvertures dans de bonnes conditions, notamment lorsque le flan est en carton ondule, a In the case of trapezoidal flaps, this configuration is essential to allow the passage of the transverse panels through the openings in good conditions, especially when the blank is made of corrugated cardboard, a

De preference encore, chaque voles de forme trapezofdale presente des bords lateraux d'inclinaison identique a celle des bords lateraux de l'ouverture adjacente. II s'agit cependant d'une configuration preferentielle, car optimale en termes d'utilisation de la matiere et de facilite de fabrication, mais non exclusive: I'inclinaison des bords lateraux de ltouverture peut en effet etre superieure, typiquement de quelques degree (1 a 3 ), a celle des bords lateraux des volets. Suivant une caracteristique de ['invention, I'organe de verrouillage mentionne plus haut consiste en au moins une languettedecoupee dans le fond en bordure de l'ouverture, et articulee suivant une ligne de rainage entre une position permettant le passage au-dessus audit fond, a travers ladite ouverture, de la portion centrale trapezodale du panneau transversal adjacent sur laquelle vent rabattues les portions triangulaires rattachees, et une position lui interdisant More preferably, each trapezoidal shape of the flights has lateral edges of inclination identical to that of the lateral edges of the adjacent opening. It is however a preferential configuration, because optimal in terms of use of the material and ease of manufacture, but not exclusive: the inclination of the lateral edges of the opening can indeed be greater, typically by a few degrees ( 1 to 3), to that of the lateral edges of the flaps. According to a characteristic of the invention, the locking member mentioned above consists of at least one tab cut in the bottom at the edge of the opening, and articulated along a crease line between a position allowing passage above said bottom , through the said opening, of the central trapezoidal portion of the adjacent transverse panel on which the connected triangular portions are folded down, and a position preventing it

De preference, la ligne de rainage sur laquelle s'articule chacune des Preferably, the crease line on which each of the
2 0 languettes est parallele aux lignes de rainage inverse. 2 0 tabs is parallel to the lines of reverse creasing.
De preference encore, chaque languette est de forme trapezofdale de More preferably, each tongue is trapezoidal in shape
petite base correspondent a la ligne de rainage autour de laquelle elle s'articule. small base correspond to the crease line around which it revolves.
Pour optimiser la fabrication du flan, les bords lateraux de ladite languette trapezofdale vent par exemple decoupes dans le prolongement de ceux du 2 5 voles trapezofdal adjacent, les bords lateraux audit voles presentent une inclinaison identique a celle des bords lateraux des ouvertures, et une decoupe parallele aux lignes d'articulation les separe. Dans ce cas, chacune des deux ouvertures peut de plus etre sensiblement de forme identique aux deux parties reunies. Suivant ce dernier mode de realisation, I'invention permet de ne pratiquer, dans le fond, que le nombre minimal de decoupes, et d'optimiser To optimize the manufacture of the blank, the lateral edges of said trapezoidal tongue are cut, for example, in continuation of those of the adjacent trapezoidal flaps, the lateral edges of said flaps have an inclination identical to that of the lateral edges of the openings, and a cutout. parallel to the articulation lines separate them. In this case, each of the two openings can moreover be substantially identical in shape to the two joined parts. According to this last embodiment, the invention allows practicing, in the background, only the minimum number of cuts, and optimizing
ainsi le procede de fabrication.thus the manufacturing process.
L'invention permet d'obtenir en definitive trots differentes formes de volume de conditionnement en fonction de oc: - Si oc est egal a 0, les panneaux longitudinaux vent perpendiculaires au 3 5 fond du plateau et le volume de conditionnement audit plateau est alors sensiblement de forme parallelepipedique rectangle; - Si x est positif, les panneaux longitudinaux vent inclines vers l'interieur du plateau; - Si oc est negatif, les panneaux longitudinaux vent inclines vers The invention makes it possible to ultimately obtain different shapes of packaging volume as a function of oc: - If oc is equal to 0, the longitudinal wind panels perpendicular to the bottom of the tray and the packaging volume at said tray is then substantially rectangular parallelepipedic shape; - If x is positive, the longitudinal panels are inclined towards the interior of the plate; - If oc is negative, the longitudinal panels are inclined towards
l'exterieurdu plateau.the outside of the plateau.
11 est a noter que la valeur positive ou negative de oc ne fait pas reference a It should be noted that the positive or negative value of oc does not refer to
un sens de rotation trigonometrique ou anti-trigonometrique. a direction of rotation trigonometric or anti-trigonometric.
De preference, oc est compris dans un intervalle de -5 a +5 . Par exemple, lorsque oc est a egale a +5 , les lignes de rainage obliques telles que mentionnees au paragraphe precedent forment un angle de sensiblement 50 avec la ligne de rainage inverse autour de laquelle pivote le panneau transversal. Cela permet done d'obtenir au final un plateau dont les panneaux longitudinaux vent legerement inclines vers l'interieur, en principe d'un angle de 85 par rapport au fond. Ce conditionnement peut ainsi servir a maintenir en place par exemple un panneau rectangulaire en bois ou agglomere constituent un element de meuble, place a plat sur le fond du conditionnement, Preferably, oc is in the range of -5 to +5. For example, when oc is equal to +5, the oblique crease lines as mentioned in the preceding paragraph form an angle of approximately 50 with the reverse crease line around which the transverse panel pivots. This therefore makes it possible in the end to obtain a tray whose longitudinal panels are slightly inclined towards the interior, in principle at an angle of 85 relative to the bottom. This packaging can thus be used to hold in place for example a rectangular wooden or agglomerated panel constituting a piece of furniture, placed flat on the bottom of the packaging,

Les plateaux proposes jusqu'ici dans l'art anterieur vent certes egalement souvent realises a partir d'un flan unique de forme generale rectangulaire preplie et predecoupe de maniere plus ou moins complexe pour ce qui concerne les parties notamment servant a son assemblage final (rabats, pastes, languettes, etc...). Les operations de predecoupage de ces derrieres parties realisees au niveau de ses bords peripheriques engendrent cependant dans la plupart des cas des chutes qui, en s'additionnant avec le nombre des plateaux produits, constituent en definitive une quantite non negligeable de matiere premiere perdue. L'invention permet de supprimer cet inconvenient par le fait que le flan unique reste, meme apres traitement (rainage / decoupage), de forme rectangulai re et depourvu de su rfaces deco u pees. Les pan neaux transversaux et lateraux presentent alors cette meme forme de rectangle, les panneaux de The trays proposed so far in the prior art are also often often produced from a single blank of generally rectangular shape pre-cut and precut in a more or less complex manner as regards the parts in particular used for its final assembly (flaps , pastes, tongues, etc ...). The operations of precutting of these back parts carried out at the level of its peripheral edges however generate in most cases falls which, by adding up to the number of the plates produced, constitute definitively a not insignificant quantity of lost raw material. The invention makes it possible to eliminate this drawback by the fact that the single blank remains, even after treatment (creasing / cutting), of rectangular shape and devoid of decorative surfaces. The transverse and lateral panels then present this same form of rectangle, the panels of
liaison etant subsequemment rectangulaire ou carre. connection being subsequently rectangular or square.
II est cependant possible que le flan soit par exemple de forme octogonale, les panneaux de liaison etant alors de forme triangulaire au lieu d'etre de forme rectangulaire. L'invention concerne egalement un procede de mise en volume d'un plateau tel que defini precedemment a partir d'un flan unique en carton, carton ondule ou materiau en feuille analogue comprenant une partie de fond rectangulaire 3 5 caracterise en ce qu'il comprend les etapes suivantes: - dresser au-dessus audit fond autour de premieres lignes de rainage les panneaux longitudinaux de maniere a ce que chacun fasse un angle de (90 -cc) avec ledit fond; It is however possible that the blank is for example of octagonal shape, the connecting panels then being of triangular shape instead of being rectangular. The invention also relates to a method for setting the volume of a tray as defined above from a single blank of cardboard, corrugated cardboard or similar sheet material comprising a rectangular bottom part 3 5 characterized in that it comprises the following steps: - erect above said bottom around first lines of creasing the longitudinal panels so that each makes an angle of (90 -cc) with said bottom;

II est a noter que l'ordre des deux derrieres etapes du procede peut etre inverse. L'invention va a present etre decrite plus en detail, en reference aux figures annexees, pour lesquelles: - la figure 1 est une vue a plat d'un flan a partir duquel est obtenu un plateau selon ['invention; - les figures 2, 3, 4, 5 et 6 representent des vues en perspective montrant le deploiement progressif audit flan jusqu'a l'obtention du It should be noted that the order of the two last stages of the process can be reversed. The invention will now be described in more detail, with reference to the appended figures, for which: - Figure 1 is a flat view of a blank from which a tray according to the invention is obtained; - Figures 2, 3, 4, 5 and 6 show perspective views showing the gradual deployment of said blank until obtaining the

En reference a la figure 1, le flan unique (1), par exemple en carton, est de forme rectangulaire et comporte une partie centrale rectangulaire formant le fond (2) du plateau. Cel ui-ci est entou re de de ux pan neaux rectangulaires longitudinaux (3, 5) de memes dimensions articules suivant des lignes de rainage (15, 17), et de deux panneaux rectangulaires transversaux (4, 6) de Referring to Figure 1, the single blank (1), for example of cardboard, is rectangular and has a rectangular central portion forming the bottom (2) of the tray. This is surrounded by two longitudinal rectangular panels (3, 5) of the same dimensions articulated along creasing lines (15, 17), and two rectangular transverse panels (4, 6) of
memes dimensions articules suivant des lignes de rainage inverses (16, 18) . same dimensions articulated along reverse creasing lines (16, 18).
Ce rainage est dit inverse car il est preforme pour pouvoir permettre un repli suivant une direction sensiblement opposee a celle du premier rainage (15, 17) This creasing is said to be reverse because it is preformed to be able to allow a fold in a direction substantially opposite to that of the first creasing (15, 17).

En premier lieu, les panneaux longitudinaux (3,5) et les panneaux de liaison First, the longitudinal panels (3,5) and the connecting panels
(7,10; 8, 9) vent redresses perpendiculairement au fond (2). (7,10; 8, 9) wind straightens perpendicular to the bottom (2).
En reference a la figure 3, les panneaux de liaison (7, 8) vent ensuite replies vers l'interieur, de 90 autour des lignes de rainage (19, 20), sensiblement le long d'un des cotes transversaux du fond (2). Ce mouvement provoque le rabat des deux portions triangulaires (4a, 4b) sur la portion centrale trapezoldale (4c) autour des rainages obliques (27', 28'). Le panneau transversal (4) est With reference to FIG. 3, the connection panels (7, 8) are then folded inwards, by 90 around the crease lines (19, 20), substantially along one of the transverse dimensions of the bottom (2 ). This movement causes the flap of the two triangular portions (4a, 4b) on the central trapezoidal portion (4c) around the oblique grooves (27 ', 28'). The cross panel (4) is
simultanement rabattu vers le teas.simultaneously folded back towards the teas.
Le voles (11) est ensuite redresse sensiblement de 90 autour de la ligne de rainage inverse (16) pour venir en contact avec la face interieure des The fly (11) is then straightened substantially by 90 around the reverse creasing line (16) to come into contact with the inner face of the

Cette derriere figure illustre la fin de course de la portion trapezodale (4c) (voir fleche) qui traverse litteralement le plan du fond (2) par en dessous pour venir dans le volume du panneau via l'ouverture (44). La languette (13) (voir figure 4) est alors dressee vers le haut, dans une position permettant le passage de l'extremite libre de ladite portion (4c).

This behind figure illustrates the end of travel of the trapezoidal portion (4c) (see arrow) which literally crosses the plane of the bottom (2) from below to come into the volume of the panel via the opening (44). The tongue (13) (see FIG. 4) is then raised upwards, in a position allowing the passage of the free end of said portion (4c). This tongue (11) is then replaced substantially in the plane of the bottom (2) thus blocking the

La figure 6 montre le plateau (43) tel qu'il se presente lorsqu'ii est monte. Le montage de la quatrieme paroi (42) se fait en procedant de la meme maniere que pour la troisieme paroi (38) qui lui est opposee. Le volume de conditionnement a sensiblement la forme d'un parallelepipede rectangle. Les axes (47) permettent neanmoins d'imaginer la forme que produit l'inclinaison vers l'interieur des panneaux longitudinaux lorsque a est different de 0, et Figure 6 shows the plate (43) as it appears when it is mounted. The mounting of the fourth wall (42) is carried out in the same manner as for the third wall (38) which is opposite it. The packaging volume has substantially the shape of a rectangular parallelepiped. The axes (47) nevertheless make it possible to imagine the shape produced by the inclination towards the interior of the longitudinal panels when a is different from 0, and
positif. Cette inclinaison se ferait vers l'exterieur du plateau si a etait negatif. positive. This inclination would be towards the outside of the plate if it were negative.
Selon la variante illustree de ['invention, on obtient done a partir du flan unique rectangulaire (1) preplie et predecoupe de maniere a conserver son integrite, le plateau (43) qui presente, apres un montage rapide, une excellente According to the illustrated variant of the invention, there is therefore obtained from the single rectangular blank (1) pre-folded and precut so as to retain its integrity, the plate (43) which, after rapid assembly, exhibits excellent
tenue mecanique.mechanical strength.
