Abstract

The invention concerns a container obtained by folding a sheet (2) of semirigid material such as paper or cardboard, along pre-folding lines formed in said sheet and by closure with a linking element passing through holes perforated near the terminal edges of said sheet. The pre-folding lines define: (a) a first central zone (6) in the shape of a polygon with N sides, (b) N substantially rectangular second zones (7) adjacent to the N sides (18) of the first central zone (6) and, (c) N sets of third folding zones arranged between the N second zones. The invention is characterised in that in each set there are n third folding zones (8), n being an even number, each formed by an angular portion whereof the apex is more or less one the apices (9) of the central polygonal zone (6); furthermore, there are as many holes (10) as third folding zones (8) and the holes (10) are located in said third folding zones (8) such that, when the container (1) has been completely folded, the n holes (10) of a common set of third folding zones (8) are aligned outside the volume formed by the N second zones (7).

Description

RECIPIENT OBTENU PAR PLIAGE D'UNE FEUILLE DE PAPIER OU DE CARTON CONTAINER OBTAINED BY FOLDING A SHEET OF PAPER OR CARDBOARD
La présence demande concerne un récipient léger , jetable, qui est obtenu par un simple pliage d'une feuille de papier ou de carton selon des lignes de pré-pliage formées dans ladite feuille. L'invention concerne en particulier un récipient étanche à l'eau qui puisse faire office de vase pour accueillir notamment un bouquet de fleurs.The demand presence relates to a light, disposable container, which is obtained by a simple folding of a sheet of paper or cardboard according to pre-folding lines formed in said sheet. The invention relates in particular to a watertight container which can act as a vase to accommodate in particular a bouquet of flowers.
Il n'est pas toujours évident qu'un vase soit disponible pour accueillir des fleurs. De plus, les vases sont des récipients en matière cassable et qui occupent beaucoup de place, lorsqu'ils ne sont pas utilisés.It is not always obvious that a vase is available to accommodate flowers. In addition, vases are receptacles made of breakable material and which occupy a lot of space, when not in use.
On a déjà cherché à proposer des récipients qui soient éventuellement jetables et surtout faciles à stocker , sous la forme d'une simple feuille ou flan de papier ou de carton.Attempts have already been made to propose containers which are possibly disposable and above all easy to store, in the form of a simple sheet or blank of paper or cardboard.
Par exemple dans le document FR.2.778.324 , le flan£ en matière semi-rigide , par exemple en carton ondulé enduit sur au moins une face d'une matière hydrophobe, présente un contour extérieur sensiblement en forme de polygone régulier. Plusieurs séries de lignes de pliage , formées dans le matériau semi-rigide , délimitent : a) une zone centrale polygonale à N côtés , destinée à constituer le fond du récipient , b) N zones rectangulaires adjacentes au N côtés de la zone centrale, c) 2 N zones triangulaires disposées deux par deux entre les N zones rectangulaires.For example in document FR.2.778.324, the blank £ in semi-rigid material, for example corrugated cardboard coated on at least one face with a hydrophobic material, has an outer contour substantially in the shape of a regular polygon. Several series of fold lines, formed in the semi-rigid material, delimit: a) a polygonal central zone with N sides, intended to constitute the bottom of the container, b) N rectangular zones adjacent to the N sides of the central zone, c ) 2 N triangular zones arranged two by two between the N rectangular zones.
Lors de la formation du récipient, les zones rectangulaires forment les montants intérieurs du récipient. Les zones triangulaires sont repliées l'une contre l'autre et rabattues sur la face extérieure des zones rectangulaires , contre lesquelles elles sont collées. Dans l'exemple illustré, des trous sont percés selon les lignes de pliage , lesdits trous définissant des épaulements par lesquels le récipient peut venir en appui sur un support.When the container is formed, the rectangular areas form the interior uprights of the container. The triangular areas are folded against each other and folded down on the outside of the rectangular areas, against which they are glued. In the example illustrated, holes are drilled along the fold lines, said holes defining shoulders by which the container can come to bear on a support.
L'inconvénient majeur d'un tel récipient est que pour réaliser sa fermeture il est nécessaire de disposer de colle, avec de plus le risque que le collage ne soit pas fait dans de bonnes conditions et que le récipient s'ouvre en tout ou partie sous la pression de l'eau qu'il contient.The major disadvantage of such a container is that to achieve its closing it is necessary to have glue, with the risk that the gluing is not done in good conditions and that the container opens in whole or in part under the pressure of the water it contains.
Dans le document EP.28O.721, cet inconvénient du collage est résolu par l'utilisation d'un lien , des trous étant percés vers les extrémités supérieures des zones rectangulaires formant les montants latéraux du récipient dont le fond est en l'occurrence de forme carrée. Cependant, comme cela apparaît clairement à l'examen de la figure 2 , dans ce document les zones de pliage qui s'étendent entre les montants latéraux sont repliées totalement vers l'intérieur dudit récipient de sorte que cela limite considérablement le volume intérieur disponible de celui-ci.In document EP.28O.721, this drawback of bonding is solved by the use of a link, holes being drilled towards the upper ends of the rectangular zones forming the lateral uprights of the container, the bottom of which is in this case square shape. However, as is clear from an examination of FIG. 2, in this document the folding zones which extend between the lateral uprights are folded completely towards the interior of said container so that this considerably limits the available internal volume of this one.
Le but de la présente invention est de remédier à cet inconvénient. Ce but est parfaitement atteint par le récipient qui , de manière connue , est obtenu par pliage d'une feuille d'un matériau semi-rigide tel que du papier ou du carton, selon des lignes de pré-pliage formées dans ladite feuille et par fermeture à l'aide d'un lien passant par des trous percés vers les bords extrêmes de ladite feuille. De manière également connue, les lignes de pré-pliage délimitent : a) une première zone centrale de forme polygonale à N côtés , b) N secondes zones , sensiblement rectangulaires , adjacentes auxThe object of the present invention is to remedy this drawback. This object is perfectly achieved by the container which, in known manner, is obtained by folding a sheet of a semi-rigid material such as paper or cardboard, along pre-folding lines formed in said sheet and by closing with a link passing through holes drilled towards the extreme edges of said sheet. In a manner also known, the pre-folding lines delimit: a) a first central zone of polygonal shape with N sides, b) N second zones, substantially rectangular, adjacent to the
N côtés de la première zone centrale et , c) N ensembles de troisièmes zones de pliage, disposés entre les N zones.N sides of the first central zone and, c) N sets of third folding zones, arranged between the N zones.
De manière caractéristique , selon l'invention, dans chaque ensemble il y a n troisièmes zones de pliage , n étant un nombre pair, chacune étant constituée par une portion angulaire dont le sommet est approximativement l'un des sommets de la zone centrale polygonale ; de plus il y a autant de trous que de troisièmes zones de pliage ; enfin les trous sont localisés dans lesdites troisièmes zones de pliage en sorte que 7ie pliage du récipient étant réalisé , les n trous d'un même ensemble de troisièmes zones de pliage sont alignés et extérieurs au volume développé par les N secondes zones.Typically, according to the invention, in each assembly there are third folding zones, n being an even number, each consisting of an angular portion whose apex is approximately one of the apices of the polygonal central zone; moreover there are as many holes as there are third folding zones; finally the holes are located in said third folding zones so that 7 ie the container is folded, the n holes of the same set of third folding zones are aligned and outside the developed volume by the N second zones.
Ainsi contrairement à l'enseignement du document EP.28O.721, les troisièmes zones de pliage sont au moins partiellement formées vers l'extérieur du volume délimité par les secondes zones rectangulaires , ce qui augmente corrélativement le volume intérieur disponible du récipient. De plus , après pliage , il suffit d'enfiler le lien dans les trous alignés des zones de pliage et d'enserrer le lien sur tout le pourtour extérieur du récipient dont les montants sont formés par les N secondes zones , sensiblement rectangulaires. Dans un mode préféré de réalisation, la zone centrale est un carré et le nombre n de troisièmes zones de pliage est égal à 6.Thus, contrary to the teaching of document EP.28O.721, the third folding zones are at least partially formed towards the outside of the volume delimited by the second rectangular zones, which correlatively increases the available internal volume of the container. In addition, after folding, it suffices to thread the link into the aligned holes of the folding zones and to grip the link around the entire outer periphery of the container, the uprights of which are formed by the N second zones, which are substantially rectangular. In a preferred embodiment, the central zone is a square and the number n of third folding zones is equal to 6.
Avantageusement une entaille est pratiquée entre deux trous adjacents en sorte de permettre l'introduction du lien après pliage des troisièmes zones de pliage. De préférence , dans ce cas , l'entaille est complétée par une découpe , par exemple triangulaire , dans chaque troisième zone de pliage de part et d'autre de la ligne de pliage correspondante. Selon cette disposition particulière , lors de la mise en forme du récipient , il suffit pour chaque ensemble de troisièmes zones de pliage d'introduire le lien dans les différentes entailles et de le glisser jusqu'aux trous correspondants. Il n'est plus nécessaire d'enfiler le lien dans les différents trous adjacents.Advantageously, a notch is made between two adjacent holes so as to allow the introduction of the link after folding of the third folding zones. Preferably, in this case, the notch is completed by a cut, for example triangular, in each third folding zone on either side of the corresponding folding line. According to this particular arrangement, during the shaping of the container, it suffices for each set of third folding zones to introduce the link into the different notches and to slide it to the corresponding holes. It is no longer necessary to thread the link in the different adjacent holes.
Dans une variante préférée de réalisation dans laquelle le récipient a une forme sensiblement pyramidale, ledit récipient comporte en outre 2 N lignes de pré-pliage délimitant , vers l'intérieur des N secondes zones sensiblement rectangulaires, 2N quatrièmes zones de pliage , non perforées , chacune étant constituée par une portion angulaire dont le sommet est approximativement l'un des sommets du polygone constituant la première zone centrale et ayant un côté commun avec une seconde zone , sensiblement rectangulaire. La particularité de la présence de ces quatrièmes zones est d'une part de modifier la configuration des montants délimitant intérieurement le volume du récipient , lesdits montants n'étant plus les N zones sensiblement rectangulaires mais de ce fait N zones ayant la configuration d'un trapèze isocèle dont la grande base est l'un des côtés du polygone de la première zone centrale. Le récipient a donc une forme pyramidale. D'autre part les N ensembles de troisièmes zones de pliage , lorsque le récipient est mis en forme , ont de ce fait une partie qui se trouve à l'intérieur du volume intérieur du récipient, celle qui est en regard des quatrièmes zones de pliage.In a preferred alternative embodiment in which the container has a substantially pyramidal shape, said container further comprises 2 N pre-folding lines delimiting, towards the interior of the N second substantially rectangular zones, 2N fourth folding zones, non-perforated, each consisting of an angular portion, the apex of which is approximately one of the vertices of the polygon constituting the first central zone and having a common side with a second zone, substantially rectangular. The particularity of the presence of these fourth zones is on the one hand to modify the configuration of the amounts internally delimiting the volume of the container, said uprights no longer being the N substantially rectangular zones but therefore N zones having the configuration of an isosceles trapezium whose large base is one of the sides of the polygon of the first central zone. The container therefore has a pyramidal shape. On the other hand, the N sets of third folding zones, when the container is shaped, therefore have a part which is inside the interior volume of the container, that which is opposite the fourth folding zones. .
Dans ce cas, de préférence , les 2 N lignes complémentaires de pré- pliage , délimitant les quatrièmes zones de pliage , sont telles qu'elles affleurent les trous alignés , lorsque les troisième et quatrième zones de pliage sont en position repliée. Dans ces conditions, lorsque le lien est mis en place pour la fermeture du récipient , il enserre au plus près les faces extérieures des N montants du récipient. S'agissant d'un récipient étanche destiné à servir de vase , le matériau semi-rigide , du type papier ou carton , a au moins une face qui est traitée hydrophobe.In this case, preferably, the 2 N complementary pre-folding lines delimiting the fourth folding zones are such that they are flush with the aligned holes, when the third and fourth folding zones are in the folded position. Under these conditions, when the link is put in place for closing the container, it encloses the outer faces of the N uprights of the container as closely as possible. Being a sealed container intended to serve as a vase, the semi-rigid material, of the paper or cardboard type, has at least one side which is treated hydrophobic.
Dans un autre mode de réalisation d'un récipient étanche , la feuille de matériau semi-rigide , notamment papier ou carton , n'est pas hydrophobe ni traitée hydrophobe et le récipient comporte une poche intérieure hydrophobe. Eventuellement cette poche peut être constituée par une feuille à plat , qui sera mise en forme à l'occasion ou à l'issue de la mise en forme du récipient. Eventuellement , la feuille de matériau hydrophobe constituant ladite poche est collée localement sur la feuille de matière semi-rigide constituant le récipient , vers les bords supérieurs des N secondes zones sensiblement rectangulaires. Ainsi la poche se forme en même temps que se constitue le récipient , par pliage selon les lignes de pré-pliage de la feuille semi-rigide.In another embodiment of a sealed container, the sheet of semi-rigid material, in particular paper or cardboard, is not hydrophobic or hydrophobic treated and the container has an interior hydrophobic pocket. Optionally, this pocket may consist of a flat sheet, which will be shaped on the occasion or at the end of the shaping of the container. Optionally, the sheet of hydrophobic material constituting said pocket is bonded locally on the sheet of semi-rigid material constituting the container, towards the upper edges of the N second substantially rectangular zones. Thus the pocket is formed at the same time as the container is formed, by folding along the pre-folding lines of the semi-rigid sheet.
Il a été remarqué que lorsque le nombre n de troisièmes zones de pliage est élevé , notamment égal ou supérieur à 6, cela peut occasionner une certaine fragilisation de la feuille de matériau semi-rigide à proximité des différents sommets du polygone de la première zone centrale, destinée à constituer le fond du récipient. En effet c'est ce sommet qui est le point de départ desdites lignes de pliage . Pour éviter cette fragilisation et surtout pour faciliter ce pliage , il est possible de prévoir des trous au niveau des N dits sommets. Bien sûr dans ce cas , si l'on veut un récipient qui soit étanche , il faut nécessairement y adjoindre une poche intérieure dans un matériau hydrophobe.It has been noted that when the number n of third folding zones is high, in particular equal to or greater than 6, this can cause a certain embrittlement of the sheet of semi-rigid material nearby. different vertices of the polygon of the first central zone, intended to constitute the bottom of the container. Indeed, it is this vertex which is the starting point of said fold lines. To avoid this embrittlement and above all to facilitate this folding, it is possible to provide holes at the level of the N so-called vertices. Of course in this case, if you want a container that is waterproof, you must necessarily add an inner pocket in a hydrophobic material.
Chacune des n troisièmes zones de pliage est une portion angulaire ayant comme sommet sensiblement l'un des sommets du polygone constituant la première zone centrale. Toutes ces troisième zones de pliage sont identiques les unes aux autres. De préférence le contour extérieur de la feuille semi-rigide , au niveau de ces troisièmes zones de pliage est soit un arc de cercle soit une succession de lignes brisées de sorte que chaque troisième zone de pliage a la configuration d'un triangle isocèle.Each of the n third folding zones is an angular portion having as apex substantially one of the vertices of the polygon constituting the first central zone. All these third folding zones are identical to each other. Preferably the outer contour of the semi-rigid sheet, at the level of these third folding zones is either an arc of a circle or a succession of broken lines so that each third folding zone has the configuration of an isosceles triangle.
La présente invention sera mieux comprise à la lecture de la description qui va être faite d'un exemple préféré de réalisation d'un récipient pyramidal à fond carré et à quatre ensembles de six troisièmes zones de pliage , illustré dans le dessin annexé dans lequel : La figure 1 est une représentation à plat de la feuille de carton permettant d'obtenir le récipient par pliage,The present invention will be better understood on reading the description which will be given of a preferred embodiment of a pyramidal container with a square bottom and four sets of six third folding zones, illustrated in the appended drawing in which: FIG. 1 is a flat representation of the cardboard sheet making it possible to obtain the container by folding,
La figure 2 est une vue schématique partielle en coupe du récipient selon l'axe II-II de la figure 3 , etFIG. 2 is a partial schematic view in section of the container along the axis II-II of FIG. 3, and
La figure 3 est une vue de côté du récipient monté. Le récipient 1 qui est illustré à la figure 3 est obtenu par prélèvement et par pliage de la portion 2 de la feuille de carton 3 qui est illustrée à la figure 1. Cette feuille 3 est une feuille rectangulaire qui , pour des raisons de présentation et d'encombrement est de préférence repliée sur elle-même selon les deux axes Dl et D2. Dans l'exemple illustré , la partie supérieure 4 de la feuille 3, au-dessus de l'axe Dl, est destinée à recevoir , par impression, la notice de montage et toutes explications souhaitables. L'axe D2 est quant à lui un axe de pliage , nécessaire au montage du récipient comme cela sera compris à la lecture de la description ci-après. La portion 2 de la feuille 3 en carton, qui est la seule utile pour la réalisation du récipient 3 est facilement détachable du reste de la feuille 3 notamment par des pré-découpes semi-continues , voire en pointillés réalisées dans ladite feuille 3.Figure 3 is a side view of the mounted container. The container 1 which is illustrated in FIG. 3 is obtained by removing and folding the portion 2 of the cardboard sheet 3 which is illustrated in FIG. 1. This sheet 3 is a rectangular sheet which, for reasons of presentation and size is preferably folded back on itself along the two axes Dl and D2. In the example illustrated, the upper part 4 of the sheet 3, above the axis Dl, is intended to receive, by printing, the assembly instructions and all explanations desirable. The axis D2 is in turn a folding axis, necessary for mounting the container as will be understood on reading the description below. The portion 2 of the cardboard sheet 3, which is the only one useful for making the container 3, is easily detachable from the rest of the sheet 3, in particular by semi-continuous or even dotted pre-cuts made in said sheet 3.
Bien sûr cette présentation intégrée dans une feuille rectangulaire 3 n'est pas strictement nécessaire , le récipient 1 pouvant être obtenu directement à partir d' une feuille en carton se présentant comme la portion 2 ci-dessus. Pour cette raison, dans la suite du présent texte, la portion 2 sera dénommée sous le terme feuille.Of course, this presentation integrated into a rectangular sheet 3 is not strictly necessary, the container 1 being able to be obtained directly from a cardboard sheet presenting itself as the portion 2 above. For this reason, in the remainder of this text, portion 2 will be referred to as the sheet.
La feuille 2 comporte une pluralité de zones , délimitées par des lignes de pré-pliage , préformées dans ladite feuille 2.Sheet 2 comprises a plurality of zones, delimited by pre-folding lines, preformed in said sheet 2.
La première zone est une zone centrale 6 qui est de forme polygonale, avec un nombre N de côtés. Dans l'exemple illustré ce nombre N est égal à 4, la zone centrale 6 étant carrée. Cette zone centrale est destinée à constituer le fond du récipient 1.The first zone is a central zone 6 which is polygonal in shape, with a number N of sides. In the example illustrated, this number N is equal to 4, the central zone 6 being square. This central zone is intended to constitute the bottom of the container 1.
Les secondes zones 7 sont au nombre de N ; elles sont de forme rectangulaire et prolongent chacun des N côtés de la zone centrale 6. Elles sont destinées à constituer , au moins en partie , les montants, délimitant le volume intérieur du récipient 1.The second zones 7 are N in number; they are rectangular in shape and extend each of the N sides of the central zone 6. They are intended to constitute, at least in part, the uprights, delimiting the interior volume of the container 1.
Entre chaque seconde zone 7 se trouvent n zones de pliage 8 , qui se présentent sous la forme de portions angulaires dont le sommet est sensiblement au niveau de chacun des sommets 9 de la zone centrale 6 polygonale. Toutes ces troisièmes zones 8 ont la même configuration, avec, dans l'exemple illustré , un contour extérieur 8a qui est en arc de cercle. Ainsi , la zone centrale 6 étant un carré , les n troisièmes zones de pliage 8 entre deux secondes zones 7 forment un quart de cercle. De plus il y a donc , sur la feuille 2 , quatre ensembles de n troisièmes zones de pliage 8.Between each second zone 7 are n folding zones 8, which are in the form of angular portions whose apex is substantially at the level of each of the vertices 9 of the polygonal central zone 6. All these third zones 8 have the same configuration, with, in the example illustrated, an external contour 8a which is in an arc of a circle. Thus, the central zone 6 being a square, the n third folding zones 8 between two second zones 7 form a quarter of a circle. Furthermore, there are therefore, on sheet 2, four sets of n third folding zones 8.
Le nombre n est un nombre pair , de manière à permettre à deux zones de pliage d'être appliquées l'une contre l'autre , lors du montage du récipient 1. Ce nombre n est choisi en fonction du nombre N de côtés de la première zone 6 en fonction de l'encombrement que l'on souhaite pour le récipient 1. Par exemple , dans le cas d'une zone centrale 6 carrée , il est préférable de choisir un nombre n égal à 6 , comme dans l'exemple illustré , de manière à ce que les six troisièmes zones de pliage 8 occupent un encombrement réduit par rapport au volume extérieur du récipient 1, comme illustré à la figure 3 lorsqu'elles sont repliées l'une sur l'autre en accordéon. Bien sûr dans le cas où la zone centrale serait un hexagone ou un octogone , le nombre n pourrait être inférieur à 6 et être égal à 4 voire à 2.The number n is an even number, so as to allow two folding zones to be applied one against the other, during assembly of the container 1. This number n is chosen as a function of the number N of sides of the first zone 6 as a function of the space required for container 1. For example, in the case of a central square area 6, it is preferable to choose a number n equal to 6, as in the example illustrated, so that the six third folding areas 8 occupy a reduced space compared to the external volume of the container 1, as illustrated in FIG. 3 when they are folded one on the other in accordion. Of course in the case where the central zone is a hexagon or an octagon, the number n could be less than 6 and be equal to 4 or even 2.
Le contour extérieur 8a de chaque troisième zone de pliage 8 pourrait être rectiligne et non en arc de cercle , sans préjudice sur la formation du récipient mais simplement pour des raisons esthétiques. Chaque troisième zone de pliage 8 est percée d'un trou 10 destiné à permettre le passage d'un lien 11 dont la fonction est de réaliser la mise en forme définitive et le blocage en position du récipient 1, comme illustré à la figure 3. Les différents trous 10 sont localisés à proximité du contour extérieur 5 de la feuille 2, en sorte que le lien 11 enserre toute la périphérie supérieure du récipient 1.The outer contour 8a of each third folding zone 8 could be straight and not in an arc, without prejudice to the formation of the container but simply for aesthetic reasons. Each third folding zone 8 is pierced with a hole 10 intended to allow the passage of a link 11 whose function is to carry out the final shaping and the blocking in position of the container 1, as illustrated in FIG. 3. The different holes 10 are located near the outer contour 5 of the sheet 2, so that the link 11 encloses the entire upper periphery of the container 1.
De plus , pour faciliter l'introduction du lien jusqu'au trou 10, des entailles 12 relient deux trous 10, deux à deux , appartenant à 2 troisièmes zones de pliage 8 adjacentes. De plus , au niveau de la ligne de pré-pliage 13 séparant lesdites 2 troisièmes zones successives , est également prévue une découpe en losange 14 qui , lorsque les deux dites zones de pliage 8 sont repliées l'une contre l'autre , délimitent un cône d'introduction 15 pour le passage du lien 11 dans l'entaille 12 jusqu'au trou 8 comme cela apparaît sur le figure 3.In addition, to facilitate the introduction of the link to the hole 10, notches 12 connect two holes 10, two by two, belonging to 2 third folding zones 8 adjacent. In addition, at the pre-folding line 13 separating said 2 third successive zones, a diamond cutting 14 is also provided, which, when the two said folding zones 8 are folded one against the other, delimit a introduction cone 15 for the passage of the link 11 in the notch 12 to the hole 8 as shown in FIG. 3.
Pour obtenir un vase 1 ayant des montants latéraux de forme trapézoïdale et donnant à l'ensemble du vase une configuration pyramidale, il est également prévu dans la feuille 2 des lignes complémentaires de pré-pliage 15 qui sont situées vers l'intérieur des secondes zones 7 rectangulaires, partant de chacun des sommets 9 du polygone de la zone centrale 6. Ces lignes complémentaires de pré-pliage 15 délimitent des quatrième zones de pliage 16, ayant un côté commun 17 avec les secondes zones 7.To obtain a vase 1 having lateral uprights of trapezoidal shape and giving the entire vase a pyramidal configuration, it is also provided in sheet 2 of the lines complementary pre-folding 15 which are located towards the inside of the second rectangular zones 7, starting from each of the vertices 9 of the polygon of the central zone 6. These complementary pre-folding lines 15 delimit fourth folding zones 16, having a common side 17 with the second zones 7.
Le montage du récipient se fait en procédant aux étapes suivantes. La portion de feuille 2 ayant été prélevée de la feuille rectangulaire 3, l'utilisateur met à profit les lignes de pré-pliage déjà formées dans ladite feuille 2 d'une part pour relever , par rapport à la première région centrale 6 deux des quatre secondes zones 7 grâce aux lignes de pré-pliage 18 correspondant à deux côtés adjacents de la zone centrale 6 et d'autre part pour disposer les troisièmes zones de pliage 8 les unes contre les autres , en accordéon, selon les lignes de pré-pliage 13,13'. Plus particulièrement les lignes de pré-pliage 13 qui comportent une découpe 14 sont tournées vers l'extérieur du récipient 1 tandis que les autres lignes de pré-pliage 13' qui ne comportent pas de telles découpes sont tournées vers l'intérieur du récipient 1. De même la ligne de pré-pliage 17 qui constitue l'un des côtés de la seconde zone 7 est également tournée vers l'intérieur du récipient 1. Lorsqu'il a effectué ce pliage , l'utilisateur maintient d'une main les différents plis obtenus , se saisit du lien , l'introduit grâce aux découpes coniques 14, à travers les entailles 12 jusqu'aux trous 10 des différents plis et réalise , de préférence comme illustré à la figure 3, un double passage du lien dans les mêmes trous après avoir formé une boucle autour du contour extérieur 5 de la feuille , de manière à maintenir bloquées en position les troisièmes zones 8 et quatrièmes zones 16 les unes contre les autres. Il réalise successivement la même opération pour les zones de pliage qui se trouvent situées au niveau des autres sommets du polygone de la zone centrale 6, en s'assurant que le lien est bien appliqué également contre la face extérieure de ce qui constitue les montants du récipient 1 à savoir les secondes zones rectangulaires 7 amputées des quatrièmes zones de pliage 16. Dans l'exemple illustré à la figure 1 , les trous 10 sont disposés de manière médiane, c'est-à-dire selon la bissectrice de la portion angulaire constituant chaque troisième zone de pliage 8. Ce mode de réalisation n'est pas exclusif. Il importe de respecter deux conditions. La première est que les trous 10 soient alignés lorsque les différentes troisièmes zones 8 de pliage sont appliquées les unes contre les autres , en accordéon, de manière à permettre soit l'enfilage facile du lien 11 à travers la continuité des trous 10 superposés soit permettre l'introduction aisée grâce aux entailles 12 comme indiqué ci-dessus. Quant à la seconde condition, s'agissant d'un récipient à structure pyramidale comme décrit ci-dessus , il importe que les trous 10 soient , après repliement des quatrièmes zones de pliage 16 selon la ligne de pré-pliage 17, encore accessibles à l'utilisateur , c'est-à-dire soient situés vers l'extérieur du volume du récipient délimité par les quatre montants. Dans l'exemple illustré à la figure 3, on voit que le trou 10 est toujours extérieur à la ligne de prépliage 15 de la quatrième zone de pliage 16.The container is assembled using the following steps. The sheet portion 2 having been taken from the rectangular sheet 3, the user takes advantage of the pre-folding lines already formed in said sheet 2 on the one hand to raise, relative to the first central region 6 two of the four second zones 7 thanks to the pre-folding lines 18 corresponding to two adjacent sides of the central zone 6 and on the other hand to arrange the third folding zones 8 against each other, in accordion, according to the pre-folding lines 13.13. More particularly, the pre-fold lines 13 which include a cutout 14 are turned towards the outside of the container 1 while the other pre-fold lines 13 'which do not include such cutouts are turned towards the inside of the container 1 Similarly, the pre-folding line 17 which constitutes one of the sides of the second zone 7 is also turned towards the interior of the container 1. When this folding has been carried out, the user holds the different folds obtained, takes hold of the link, introduces it thanks to the conical cutouts 14, through the notches 12 to the holes 10 of the different folds and performs, preferably as illustrated in FIG. 3, a double passage of the link in the same holes after forming a loop around the outer contour 5 of the sheet, so as to keep locked in position the third zones 8 and fourth zones 16 against each other. It successively performs the same operation for the folding zones which are located at the level of the other vertices of the polygon of the central zone 6, ensuring that the bond is also applied correctly against the external face of what constitutes the uprights of the container 1, namely the second rectangular zones 7 amputated from the fourth folding zones 16. In the example illustrated in FIG. 1, the holes 10 are arranged in a median manner, that is to say along the bisector of the angular portion constituting each third folding zone 8. This embodiment is not exclusive . Two conditions must be met. The first is that the holes 10 are aligned when the different third folding zones 8 are applied against each other, in an accordion fashion, so as to allow either easy threading of the link 11 through the continuity of the superimposed holes 10 or allow easy introduction thanks to the notches 12 as indicated above. As for the second condition, in the case of a container with a pyramidal structure as described above, it is important that the holes 10 are, after folding of the fourth folding zones 16 along the pre-folding line 17, still accessible to the user, that is to say are located towards the outside of the volume of the container delimited by the four uprights. In the example illustrated in FIG. 3, it can be seen that the hole 10 is always outside the pre-folding line 15 of the fourth folding zone 16.
Un tel récipient peut être étanche s'il est réalisé à partir d'un matériau dont au moins la face intérieure a été traitée de manière à le rendre hydrophobe. Cependant une autre solution est d'introduire à l'intérieur du récipient , une fois celui-ci préformé ou au cours de son pliage , une poche qui est elle-même dans un matériau hydrophobe ou rendue hydrophobe par traitement.Such a container can be waterproof if it is made from a material of which at least the inner face has been treated so as to make it hydrophobic. However, another solution is to introduce inside the container, once it is preformed or during its folding, a bag which is itself made of a hydrophobic material or made hydrophobic by treatment.
C'est cette seconde variante qui sera notamment mise en œuvre pour rendre étanche et utilisable comme vase, le récipient faisant l'objet de la figure 1. En effet pour faciliter le pliage au niveau des quatre sommets 9 de la zone centrale carrée 6 , la feuille 2 a été percée de quatre découpes 20. Cette disposition facilite le pliage et également évite la fragilisation excessive, susceptible de créer des trous intempestifs , au niveau desdits sommets 9.It is this second variant which will in particular be implemented to make the container which is the subject of FIG. 1 leakproof and usable as a vase. Indeed to facilitate folding at the level of the four vertices 9 of the central square area 6, the sheet 2 has been pierced with four cutouts 20. This arrangement facilitates folding and also avoids excessive embrittlement, liable to create untimely holes, at the level of said vertices 9.
De préférence on met en œuvre , comme matériau susceptible de former une poche étanche à l'eau un matériau tel que celui qui fait l'objet du document WO.99/O8784.Preferably, as material capable of form a waterproof pocket a material such as that which is the subject of document WO.99 / O8784.
La feuille destinée à constituer la poche intérieure hydrophobe , peut être une poche ayant la même configuration extérieure que la feuille 5 2 précitée. Elle peut éventuellement , dans ce cas , être solidarisée aux secondes zones 7, en partie haute de celles-ci. Elle peut éventuellement être constituée et rapportée une fois que le récipient 1 est mis en forme. Sur la figure 2 on a représenté une poche 21. Du fait de la présence d'une partie des troisièmes zones de pliage 8 tournées vers l'intérieur du volume o intérieur du récipient 1 , il se crée entre la poche 21 et le récipient proprement dit 1 des espaces libres 22, pour le passage de l'air. Une circulation d'air peut être en particulier alimentée par ces passages sur toute la hauteur du récipient grâce aux découpes évidées 20, ce qui occasionne une circulation d'air par effet de cheminée. Ceci est tout-à-fait 5 bénéfique lorsqu'on utilise un matériau du type papier , traité conformément au procédé du document WO.99/08784 qui non seulement est hydrophobe mais qui est également perméable à l'air. On obtient ainsi une meilleure oxygénation de l'eau contenue dans la poche 20 et une meilleure conservation des fleurs qui sont stockées dans le récipient o faisant office de vase.The sheet intended to constitute the interior hydrophobic pocket, can be a pocket having the same external configuration as the aforementioned sheet 52. It can possibly, in this case, be secured to the second zones 7, in the upper part thereof. It can optionally be formed and added once the container 1 is shaped. In Figure 2 there is shown a pocket 21. Due to the presence of a portion of the third folding zones 8 facing inwardly of the interior volume of the container 1, it is created between the pocket 21 and the container itself says 1 of the free spaces 22, for the passage of air. An air circulation can in particular be supplied by these passages over the entire height of the container thanks to the recessed cutouts 20, which causes air circulation by chimney effect. This is most beneficial when using a paper type material, treated according to the method of WO.99 / 08784 which is not only hydrophobic but which is also permeable to air. This gives better oxygenation of the water contained in the bag 20 and better conservation of the flowers which are stored in the container o acting as a vase.
La présente invention n'est pas limitée au mode de réalisation qui a été décrit à titre d'exemple non exhaustif. Le lien est de préférence en raphia, qui est biodégradable et complète le côté rustique du récipient, s'agissant d'un vase pour fleurs. Le récipient peut accueillir des fleurs, 5 mais aussi une plante en pot ou tout autre objet. Le fond du récipient peut être consolidé en lui superposant, lors du montage, une pièce de renfort ayant la même configuration que la zone centrale polygonale dans un matériau plus rigide que celui de la feuille.The present invention is not limited to the embodiment which has been described by way of non-exhaustive example. The link is preferably made of raffia, which is biodegradable and completes the rustic side of the container, being a vase for flowers. The container can accommodate flowers, 5 but also a potted plant or any other object. The bottom of the container can be consolidated by superimposing on it, during assembly, a reinforcement piece having the same configuration as the central polygonal zone in a material more rigid than that of the sheet.
Le lien peut bien sûr être passé dans les trous sur la feuille à plat, 0 avant montage, et aider au pliage. Mais ceci entraîne une manipulation longue et onéreuse, qu'il est préférable d'éviter. The link can of course be passed through the holes on the flat sheet, 0 before mounting, and help with folding. But this leads to a long and expensive handling, which is preferable to avoid.
