Abstract

A tubular body has four or more fold lines, of which two (1, 4) converge towards one end of the tubular body and the two remaining ones (2, 3) converge towards the other end thereof. Two side regions (11, 13) can be folded back against the inner surface of a third region (12). The dimensions of the fourth side region (14) are such that, when the body is folded, the said region readily fits between bounding fold lines (1, 4). When the tubular body is expanded, it undergoes maximum deformation, so that it remains stable both in the folded state and in the expanded state. The invention is useful for obtaining varying shapes, stabilising the body in its expanded state and making housings to be used as disposable vases, containers for liquids or creams, or boxes.

Description

Corps tubulaire pliable, et enveloppes, notamment boîte ou vase de fleurs jetable, munies d'un tel corps Foldable tubular body, and envelopes, in particular a disposable box or vase of flowers, provided with such a body

DESCRIPTION La présente invention concerne un corps tubulaire pliable, réalisé notamment en carton, et destiné par exemple à constituer la paroi latérale d'un étui.DESCRIPTION The present invention relates to a foldable tubular body, made in particular of cardboard, and intended for example to constitute the side wall of a case.

La présente invention concerne également une enveloppe, contenant ou étui muni d'un tel corps. La présente invention s'applique notamment à la réalisation de vases de fleurs livrés plies, destinés à être conservés ou au contraire jetés après utilisation.The present invention also relates to an envelope, container or case provided with such a body. The present invention applies in particular to the production of vases of flowers delivered folded, intended to be preserved or, on the contrary, discarded after use.

On connaît de nombreuses formes d'étui pliant. Ils ont l'avantage de pouvoir être livrés à l'état plié, donc sous un faible volume, à l'utilisateur.Many forms of folding case are known. They have the advantage of being able to be delivered in the folded state, therefore in a small volume, to the user.

La plupart du temps, de tels étuis pliables ont une forme géométrique déterminée, le plus souvent parallélépipédique. En outre, chaque principe de pliage est le plus souvent lié à une forme géométrique déterminée ou à une famille restreinte de telles formes, en général peu attrayantes sur le plan esthétique.Most of the time, such foldable cases have a determined geometric shape, most often parallelepiped. In addition, each folding principle is most often linked to a specific geometric shape or to a small family of such shapes, generally unattractive from an aesthetic point of view.

Il a été imaginé selon l'invention de rechercher un principe de pliage qui permette de réaliser des formes attrayantes et variées, permettant la fantaisie et une réelle recherche esthétique. En particulier, il a été imaginé selon l'invention de réaliser des vases de. fleurs pliants, destinés à être offerts à l'état plié en même temps qu'un bouquet de fleurs. Ceci ôte à la personne recevant le bouquet le souci de la recherche, souvent difficile, d'un vase adéquat pour le contenir.It has been imagined according to the invention to search for a folding principle which makes it possible to produce attractive and varied shapes, allowing fantasy and real aesthetic research. In particular, it has been imagined according to the invention to produce vases of. folding flowers, intended to be offered in the folded state together with a bouquet of flowers. This removes from the person receiving the bouquet the concern of finding, often difficult, a suitable vase to contain it.

Le but de la présente invention est ainsi de proposer un corps tubulaire pliable dont la structure de pliage offre une grande liberté dans le choix de l'esthétique du corps tubulaire à l'état mis en volume. Suivant l'invention, le corps tubulaire pliable définissant une première, une deuxième, une troisième et une quatrième régions latérales successives reliées les unes aux autres par une première, une deuxième, une troisième et une quatrième lignes d'articulation, est caractérisé en ce que la première, la deuxième et la troisième lignes d'articulation permettent, à partir de l'état mis en volume du corps tubulaire, de rabattre la première et de la troisième régions latérales en chevauchement mutuel contre la face intérieure de la deuxième région, et de rabattre la face intérieure de la quatrième région contre celle de la première région, en ce que la deuxième et la troisième lignes d'articulation, définissant entre elles la deuxième région latérale, ou les deux autres lignes d'articulation, convergent vers l'une des extrémités du corps tubulaire, en ce que la quatrième ligne d'articulation est inversible pour passer à l'état concave jusqu'à rabattre la face extérieure de la quatrième région contre celle de la troisième région, et ce que la quatrième région est dimensionnée pour s'inscrire sensiblement sans contrainte entre la première et la quatrième lignes d'articulation lorsque les première et troisième régions sont rabattues en chevauchement contre la deuxième région.The object of the present invention is thus to provide a foldable tubular body whose folding structure offers great freedom in the choice of the aesthetics of the tubular body in the set state. According to the invention, the foldable tubular body defining a first, a second, a third and a fourth successive lateral regions connected to each other by a first, a second, a third and fourth lines of articulation, is characterized in that the first, second and third lines of articulation make it possible, from the expanded state of the tubular body, to fold down the first and the third regions lateral overlapping against the inner face of the second region, and folding the inner face of the fourth region against that of the first region, in that the second and third lines of articulation, defining between them the second lateral region , or the two other articulation lines, converge towards one of the ends of the tubular body, in that the fourth articulation line is invertible so as to pass into the concave state until the outer face of the fourth region is folded down against that of the third region, and that the fourth region is sized to fit substantially without constraint between the first and the fourth lig nes of articulation when the first and third regions are folded in overlap against the second region.

Cette structure est extrêmement simple à réaliser puisqu'il suffit de donner au corps tubulaire quatre lignes d'articulation positionnées particulièrement. Elle permet de choisir très librement la forme qu'aura le corps tubulaire à l'état mis en volume. Cette forme peut être quasiment régulière ou au contraire très irrégulière, en fonction du positionnement des lignes d'articulation. Le passage de l'état mis en volume à l'état plié et inversement est très facile. Le nombre minimum de quatre lignes d'articulation, peut être augmenté à volonté, chaque région latérale pouvant elle- même être composée de plusieurs faces.This structure is extremely simple to produce since it suffices to give the tubular body four lines of articulation positioned particularly. It allows you to choose very freely the shape that the tubular body will have in the set volume state. This shape can be almost regular or, on the contrary, very irregular, depending on the positioning of the articulation lines. The transition from the set state to the folded state and vice versa is very easy. The minimum number of four articulation lines can be increased at will, each lateral region can itself be composed of several faces.

Selon un autre aspect de l'invention, une enveloppe comprend un corps tubulaire selon le premier aspect et des moyens pour fermer l'une au moins des extrémités du corps tubulaire, de façon à réaliser une boîte. Il est également prévu selon l'invention que l'enveloppe comprenne un tel corps tubulaire et une poche étanche raccordée au pourtour intérieur du corps tubulaire, par exemple au voisinage de son extrémité supérieure, pour que l'ensemble constitue un vase de fleurs jetable.According to another aspect of the invention, an envelope comprises a tubular body according to the first aspect and means for closing at least one of the ends of the tubular body, so as to produce a box. It is also provided according to the invention that the envelope comprises such a tubular body and a sealed pocket connected to the inner periphery of the tubular body, for example in the vicinity of its upper end, so that the assembly constitutes a disposable vase of flowers.

Selon un autre aspect de l'invention, l'enveloppe, comprenant toujours le corps tubulaire du premier aspect, est fixée autour d'un contenant souple et/ou déformable pour substance liquide ou pâteuse.According to another aspect of the invention, the envelope, still comprising the tubular body of the first aspect, is fixed around a flexible and / or deformable container for liquid or pasty substance.

Il est encore prévu que le corps tubulaire fasse directement partie du contenant étanche pour substance liquide ou pâteuse. Dans un cas comme dans l'autre, l'invention permet de chasser progressivement la substance, telle que dentifrice, lait concentré, produits de nettoyage, etc, en faisant progressivement passer le corps de l'état mis en volume à l'état plié. Il est ainsi très commode d'épuiser efficacement la substance initialement contenue dans l'enveloppe. D'autres particularités et avantages de l'invention ressortiront encore de la description ci- après, relative à des exemples non limitatifs. Aux dessins annexés :It is also expected that the tubular body is directly part of the sealed container for liquid or pasty substance. In one case as in the other, the invention makes it possible to gradually remove the substance, such as toothpaste, condensed milk, cleaning products, etc., by gradually passing the body from the set state to the folded state. . It is thus very convenient to effectively exhaust the substance initially contained in the envelope. Other particularities and advantages of the invention will emerge from the description below, relating to nonlimiting examples. In the accompanying drawings:

Comme le montre la figure 3, le corps tubulaire est réalisé à partir d'un flan 21 en forme de parallélogramme raccordé d'un côté à une languette de collage 22. Depuis ce côté jusqu'au côté opposé du parallélogramme, celui-ci est subdivisé en quatre régions 11, 12, 13, 14 qui se succèdent entre une première ligne d'articulation 1 correspondant au côté du parallélogramme adjacent à la languette 22, jusqu'au côté opposé 23 du parallélogramme. Les régions 11 à 14 sont en outre séparées entre elles par une deuxième, une troisième et une quatrième lignes d'articulation 2, 3 et 4 qui s'étendent chacune entre les deux autres côtés 24 et 26 du parallélogramme. Ainsi, comme le montrent les figures 1 et 2, une fois la languette 22 collée à la région 14 de façon que la ligne d'articulation 1 se superpose au côté 23 du parallélogramme, il est formé un tube déformable ayant quatre régions latérales 11 à 14 se succédant le long de la périphérie du corps tubulaire en étant séparées les unes des autres par quatre lignes d'articulation 1, 2, 3, 4 s'étendant chacune d'une extrémité à l'autre du corps tubulaire sans se couper mutuellement. Les côtés 24 et 26 du parallélogramme forment alors les extrémités du corps tubulaire.As shown in Figure 3, the tubular body is made from a blank 21 in the form of a parallelogram connected on one side to a bonding tab 22. From this side to the opposite side of the parallelogram, it is subdivided into four regions 11, 12, 13, 14 which follow one another between a first articulation line 1 corresponding to the side of the parallelogram adjacent to the tongue 22, to the opposite side 23 of the parallelogram. The regions 11 to 14 are further separated from one another by a second, a third and a fourth articulation lines 2, 3 and 4 which each extend between the two other sides 24 and 26 of the parallelogram. Thus, as shown in FIGS. 1 and 2, once the tongue 22 is stuck to the region 14 so that the articulation line 1 is superimposed on the side 23 of the parallelogram, a deformable tube is formed having four lateral regions 11 to 14 succeeding each other along the periphery of the tubular body, being separated from each other by four articulation lines 1, 2, 3, 4 each extending from one end to the other of the tubular body without cutting each other . The sides 24 and 26 of the parallelogram then form the ends of the tubular body.

Le corps tubulaire est réalisé en une matière de préférence semi-rigide telle que du carton. La défor abilité du corps tubulaire réside d'une part dans sa structure articulée le long des lignes d'articulationThe tubular body is made of a preferably semi-rigid material such as cardboard. The deformability of the tubular body resides on the one hand in its articulated structure along the lines of articulation

I à 4, et d'autre part dans la flexibilité des régionsI to 4, and secondly in the flexibility of the regions

II à 14 entre les lignes d'articulation 1 à 4. Les lignes d'articulation sont par exemple obtenues par des affaiblissements de matière tels que des rainages du carton, ou des réductions d'épaisseur si le corps est en matière plastique. La deuxième et la troisième lignes d'articulation 2 et 3, définissant entre elles la deuxième région latérale 12, convergent vers l'une des extrémités du corps tubulaire, à savoir l'extrémité supérieure 24 dans la représentation des figures 1 à 3. Au contraire les deux autres lignes d'articulation 1 et 4 définissant entre elles la quatrième région latérale 14 convergent vers l'autre extrémité du corps tubulaire, à savoir l'extrémité inférieure 26 dans la représentation des figures 1 à 3.II to 14 between the articulation lines 1 to 4. The articulation lines are for example obtained by weakening of material such as creasing of the cardboard, or reductions in thickness if the body is made of plastic. The second and third articulation lines 2 and 3, defining between them the second lateral region 12, converge towards one of the ends of the tubular body, namely the upper end 24 in the representation of FIGS. 1 to 3. Au on the contrary, the two other articulation lines 1 and 4 defining between them the fourth lateral region 14 converge towards the other end of the tubular body, namely the lower end 26 in the representation of FIGS. 1 to 3.

La première, la deuxième et la troisième lignes d'articulation 1 à 3 permettent de rabattre la face intérieure de la quatrième région 14 contre celle de la première région 11, ainsi que la face intérieure de chacune des première et troisième régions 11 et 13 contre la face intérieure de la deuxième région 12, pour aboutir à la configuration pliée représentée à la figure 1, dans laquelle la première région latérale 11 chevauche la troisième région latérale 13. Chacune des lignes d'articulation 1 et 4 est alors entièrement située d'un même côté de l'axe de l'autre. Autrement dit, les axes géométriques 31 et 34 des lignes d'articulation 1 et 4 se coupent en un point 16 situé en dehors de ces deux lignes, c'est-à-dire dans le prolongement de celles-ci. A la limite, il est possible que le point 16 soit situé à une extrémité commune des lignes 1 et 4, comme on le verra dans l'un des exemples de dimensionnement donnés en référence aux figures 5 à 13.The first, second and third articulation lines 1 to 3 allow the inner face of the fourth region 14 to be folded against that of the first region 11, as well as the inner face of each of the first and third regions 11 and 13 against the inner face of the second region 12, to lead to the folded configuration shown in the figure 1, in which the first lateral region 11 overlaps the third lateral region 13. Each of the articulation lines 1 and 4 is then entirely situated on the same side of the axis of the other. In other words, the geometric axes 31 and 34 of the articulation lines 1 and 4 intersect at a point 16 situated outside these two lines, that is to say in the extension of these. Ultimately, it is possible that point 16 is located at a common end of lines 1 and 4, as will be seen in one of the design examples given with reference to FIGS. 5 to 13.

Ce type de chevauchement implique que, le long de l'extrémité 24 du corps tubulaire, la somme des longueurs Lx et L3 (figure 1) de la première et de la troisième régions latérales soit supérieure, d'une part à la longueur L2 de la deuxième région latérale 12 et d'autre part à la longueur L4 de la quatrième région latérale 14. Ce qui précède s'exprime de la façon suivante :This type of overlap implies that, along the end 24 of the tubular body, the sum of the lengths L x and L 3 (FIG. 1) of the first and third lateral regions is greater, on the one hand than the length L 2 of the second lateral region 12 and on the other hand to the length L 4 of the fourth lateral region 14. The above is expressed as follows:

Lι + L3 > L2 Ll + L3 > L4. L ι + L 3> L 2 L l + L 3> L 4.

Les même constatations peuvent être faites le long de l'extrémité inférieure 26. La quatrième région latérale 14 est dimensionnée pour s'étendre sans déformation notable entre les lignes d'articulation 1 et 4 ainsi positionnées l'une par rapport à l'autre. Cette configuration pliée du corps tubulaire est permise par la propriété de la quatrième ligne d'articulation 4 de prendre un état inversé, c'est-à-dire saillant vers l'intérieur du tube, de manière que la quatrième région latérale s'appuie par sa face extérieure contre la face extérieure de la troisième région latérale. La configuration pliée, représentée à la figure 1, constitue pour le corps tubulaire un état de déformation minimale dans lequel la seule énergie élastique emmagasinée est celle, éventuelle, de déformation des lignes d'articulation 1 à 4.The same observations can be made along the lower end 26. The fourth lateral region 14 is dimensioned to extend without appreciable deformation between the articulation lines 1 and 4 thus positioned relative to one another. This folded configuration of the tubular body is enabled by the property of the fourth articulation line 4 to assume an inverted state, that is to say protruding towards the inside of the tube, so that the fourth lateral region is supported by its outer face against the outer face of the third lateral region. The folded configuration, represented in FIG. 1, constitutes for the tubular body a state of minimal deformation in which the only elastic energy stored is that, if any, of deformation of the articulation lines 1 to 4.

Le corps tubulaire est capable de passer de cette configuration pliée à la configuration mise en volume de la figure 2 en ouvrant la première région latérale 11 par rapport à la deuxième région 12 autour de la ligne 2 puis en poussant la quatrième ligne d'articulation 4 vers l'extérieur. On passe ainsi par un maximum de déformation sensiblement lorsque la troisième et la quatrième régions 13 et 14 sont à peu près coplanaires, puis l'énergie de déformation diminue à mesure que la ligne d'articulation 4 devient plus convexe vers l'extérieur du corps tubulaire, jusqu'à atteindre un deuxième minimum lorsqu'est atteinte la configuration, par conséquent stable, de la figure 2. Dans cet exemple, au moins la première et la troisième régions latérales prennent alors une configuration courbe, les quatre lignes d'articulation étant convexes vers l'extérieur du corps tubulaire. Dans la variante de réalisation de la figure 4, on a ajouté deux lignes d'articulation supplémentaires 6 et 9 chacune selon une diagonale de la première région 11 et respectivement de la troisième région 13, qui se trouvent ainsi subdivisées chacune en deux faces lia, 11b et respectivement 13a, 13b. Toutes ces faces peuvent ainsi prendre des formes sensiblement planes lorsque le corps tubulaire est à l'état mis en volume. Les lignes d'articulation 6 et 9 sont représentées en traits mixtes à double point à la figure 3. La ligne d'articulation 6 s'étend entre l'angle supérieur de la deuxième région et l'angle inférieur de la quatrième région, autrement dit selon la grande diagonale de la première région 11 et elle définit une arête concave lorsque le corps tubulaire est en volume. Au contraire, la ligne d'articulation supplémentaire 9 s'étend selon la petite diagonale de la troisième région 13, donc entre l'angle supérieur de la quatrième région 14 et l'angle inférieur de la deuxième région 12, et elle définit une arête convexe sur le corps tubulaire à l'état mis en volume. Ceci n'est qu'illustratif, et on aurait pu réaliser deux arêtes concaves selon les deux grandes diagonales des régions 11 et 13, ou deux arrêtes convexes selon les deux petites diagonales, on aurait pu également placer la ligne de pliage supplémentaire dans des positions autres que diagonales.The tubular body is capable of passing from this folded configuration to the volume configuration of FIG. 2 by opening the first lateral region 11 relative to the second region 12 around the line 2 and then pushing the fourth articulation line 4 outwards. We thus go through a maximum of deformation substantially when the third and fourth regions 13 and 14 are roughly coplanar, then the energy of deformation decreases as the articulation line 4 becomes more convex towards the outside of the body. tubular, until reaching a second minimum when the configuration, therefore stable, of Figure 2 is reached. In this example, at least the first and third lateral regions then take a curved configuration, the four lines of articulation being convex towards the outside of the tubular body. In the variant embodiment of FIG. 4, two additional articulation lines 6 and 9 have each been added along a diagonal of the first region 11 and respectively of the third region 13, which are thus each subdivided into two faces 11a, 11b and 13a, 13b respectively. All of these faces can thus take on substantially planar shapes when the tubular body is in the set state. The articulation lines 6 and 9 are shown in double-dashed dashed lines in FIG. 3. The articulation line 6 extends between the upper corner of the second region and the lower corner of the fourth region, otherwise said along the long diagonal of the first region 11 and it defines a concave edge when the tubular body is in volume. On the contrary, the additional articulation line 9 extends along the small diagonal of the third region 13, therefore between the upper corner of the fourth region 14 and the lower corner of the second region 12, and it defines an edge convex on the tubular body in the set state. This is only illustrative, and we could have produced two concave edges along the two large diagonals of regions 11 and 13, or two convex edges along the two small diagonals, we could also have placed the additional fold line in positions other than diagonal.

A partir de l'état mis en volume représenté aux figures 2 et 4, il est facile de plier le corps tubulaire pour revenir à la configuration de la figure 1, qui s'applique également à l'exemple de la figure 4 à l'état plié. Pour cela, il suffit dans un premier temps d'appliquer une poussée P (figure 2) sur la ligne d'articulation 4, de préférence au voisinage de l'extrémité 24 du corps tubulaire le long de laquelle la quatrième région latérale 14 est la plus longue. Ceci permet de franchir la position où l'énergie de déformation est maximale. Après cela, le pliage se poursuit quasiment seul, mais on peut bien entendu l'aider en rabattant la première région 11 contre la deuxième région 12. Au besoin, un repère 27 (figures 2 et 4) peut être prévu pour indiquer le point du corps tubulaire où la pression P doit être exercée pour provoquer le pliage. L'observation de la figure 1 permet d'apprécier qu'à l'état plié, la position relative des lignes d'articulation 1 et 4 serait la même si l'on plaçait la troisième région 13 en chevauchement sur, et non plus sous, la première région 11. Par conséquent, dans ce mode de pliage également, la quatrième région latérale relie sans contrainte les lignes d'articulation 1 et 4.From the set state shown in Figures 2 and 4, it is easy to fold the tubular body to return to the configuration of Figure 1, which also applies to the example of Figure 4 to the folded state. For this, it suffices at first to apply a thrust P (FIG. 2) on the articulation line 4, preferably in the vicinity of the end 24 of the tubular body along which the fourth lateral region 14 is the longer. This makes it possible to cross the position where the deformation energy is maximum. After that, the folding continues almost alone, but it can of course be helped by folding the first region 11 against the second region 12. If necessary, a mark 27 (Figures 2 and 4) can be provided to indicate the point of the tubular body where pressure P must be exerted to cause folding. The observation of FIG. 1 makes it possible to appreciate that in the folded state, the relative position of the articulation lines 1 and 4 would be the same if the third region 13 were overlapped on, and no longer under , the first region 11. Consequently, in this folding mode also, the fourth lateral region connects without constraint the articulation lines 1 and 4.

Dans ce cas la quatrième région se replie par sa face intérieure contre la troisième région et par sa face extérieure contre la première région. Il est pour cela nécessaire que la première ligne d'articulation 1 puisse s'inverser pour former un pli concave et que la quatrième ligne d'articulation 4 puisse former un pli convexe. Dans le cas d'une réalisation en carton, l'un - 9 - ou l'autre des deux modes de pliage est en général possible. Un deuxième repère 28 (figure 2) peut être prévu pour indiquer sur la ligne 1 le point où l'application d'une pression de fermeture Q permet le pliage selon le deuxième mode. Conceptuellement, les deux modes de pliage peuvent être décrits identiquement, à condition de permuter convenablement les noms donnés aux régions latérales et aux lignes d'articulation.In this case the fourth region folds back by its inner face against the third region and by its outer face against the first region. It is therefore necessary that the first line of articulation 1 can be inverted to form a concave fold and that the fourth line of articulation 4 can form a convex fold. In the case of a cardboard production, one - 9 - or the other of the two folding modes is generally possible. A second mark 28 (Figure 2) can be provided to indicate on line 1 the point where the application of a closing pressure Q allows folding according to the second mode. Conceptually, the two folding modes can be described identically, provided that the names given to the lateral regions and to the articulation lines are properly swapped.

L'exemple des figures 5 à 13 ne sera décrit que pour ses différences par rapport au précédent, et les numéros de référence seront conservés pour désigner les éléments analogues. Dans cet exemple, le corps tubulaire possède huit faces sensiblement égales constituées par des triangles, tous ou certains seulement ayant un sommet tronqué. Ces triangles se succèdent tête-bêche de façon que le corps tubulaire ait deux extrémités de forme carrée, dont certains au moins des sommets sont biseautés. Le carré d'une extrémité est décalé de 45° autour de l'axe du corps par rapport à celui de l'autre extrémité. Le flan prévu pour réaliser un tel corps tubulaire (figure 5) comporte comme précédemment des première, deuxième, troisième, et quatrième lignes d'articulation 1, 2, 3 et 4 représentées par des traits pleins, et des lignes d'articulation supplémentaires 6, 7, 8 et 9 représentées en traits mixtes pour permettre de les distinguer plus facilement. Les première et troisième régions latérales 11 et 13 ont sensiblement la forme de parallélogrammes et les lignes de pliage supplémentaires 6 et 9 s'étendent sensiblement selon la petite diagonale de ces parallélogrammes de façon à faire apparaître des arêtes supplémentaires convexes comme le visualise la figure 13. Les lignes de pliage supplémentaires 7 et 8 subdivisent la deuxième région 12 en trois faces triangulaires. Les lignes 7 et 8 s'étendent chacune depuis le milieu du bord le plus long de la région 12 jusqu'à l'une respective des extrémités de son bord le plus court. La quatrième région 14 ne correspond qu'à un seul triangle. Les faces lia et 11b de la région 11 sont situées aux deux extrémités du flan ce qui permet de réaliser le collage avec la languette 22 le long de la ligne d'articulation supplémentaire 6. Ainsi, le collage est plus fiable car les lignes supplémentaires sont moins sollicitées que les lignes 1 à 4 lors des opérations de pliage et mise en volume du corps.The example of FIGS. 5 to 13 will only be described for its differences from the previous one, and the reference numbers will be kept to designate the similar elements. In this example, the tubular body has eight substantially equal faces formed by triangles, all or some only having a truncated top. These triangles succeed each other head to tail so that the tubular body has two square ends, at least some of the vertices of which are bevelled. The square of one end is offset by 45 ° around the axis of the body with respect to that of the other end. The blank provided for producing such a tubular body (FIG. 5) comprises, as before, first, second, third and fourth articulation lines 1, 2, 3 and 4 represented by solid lines, and additional articulation lines 6 , 7, 8 and 9 shown in dashed lines to make it easier to distinguish them. The first and third lateral regions 11 and 13 have substantially the shape of parallelograms and the additional fold lines 6 and 9 extend substantially along the small diagonal of these parallelograms so as to reveal additional convex edges as shown in FIG. 13 The additional fold lines 7 and 8 subdivide the second region 12 into three triangular faces. Lines 7 and 8 each extend from the middle of the longest edge of region 12 to a respective one of the ends of its shortest edge. The fourth region 14 corresponds to only one triangle. The faces 11a and 11b of the region 11 are located at the two ends of the blank which allows bonding with the tongue 22 along the additional articulation line 6. Thus, the bonding is more reliable because the additional lines are less stressed than the lines 1 to 4 during the folding operations and volume setting of the body.

Les figures 6 à 8 montrent que par pliages successifs du flan d'abord le long de la ligne d'articulation 3 puis en sens inversé le long de la ligne d'articulation 4 puis dans le sens naturel le long de la ligne 2 et enfin le long de la ligne 1 on amène la face lia à venir se superposer à la languette 22 préalablement encollée pour obtenir directement le corps tubulaire à l'état plié.Figures 6 to 8 show that by successive folds of the blank first along the line of articulation 3 then in reverse direction along the line of articulation 4 then in the natural direction along the line 2 and finally along line 1, the face 11a is brought to be superimposed on the tongue 22 previously glued to directly obtain the tubular body in the folded state.

Pour que cette fabrication par pliages successifs soit réalisable, il faut avoir au préalable positionné les lignes d'articulation 1 à 4 de façon que la quatrième région s'inscrive sensiblement sans contrainte entre les lignes d'articulation 1 et 4 à l'état plié.For this manufacture by successive folding to be feasible, it is necessary to have previously positioned the articulation lines 1 to 4 so that the fourth region is inscribed substantially without constraint between the articulation lines 1 and 4 in the folded state .

Dans l'exemple des figures 5 à 13, cela nécessite de légers écarts par rapport à la stricte égalité des huit faces triangulaires. En particulier l'examen de la figure 9 permet de comprendre, sans tenir compte pour 1'instant des sommets tronqués de certaines faces triangulaires, que si les bords B2- et B4 de la deuxième et de la quatrième région 12, 14 le long de l'extrémité supérieure du corps sont d'égale longueur, les bords Bi et B3 ne peuvent pas avoir eux aussi cette même longueur puisqu'ils sont sensiblement positionnés comme les diagonales d'un rectangle dont deux côtés opposés seraient B2 et B4. On sait en effet que les diagonales d'un rectangle sont plus longues que chacun de ses côtés. On va donc choisir chacun des bords B1 et B3 un peu plus long que chacun des bords B2 et B4.In the example of FIGS. 5 to 13, this requires slight deviations from the strict equality of the eight triangular faces. In particular the examination of FIG. 9 makes it possible to understand, without taking account for the moment of the truncated vertices of certain triangular faces, that if the edges B 2 - and B 4 of the second and of the fourth region 12, 14 the along the upper end of the body are of equal length, the edges Bi and B 3 cannot also have this same length since they are substantially positioned like the diagonals of a rectangle whose two opposite sides would be B 2 and B 4 . We know that the diagonals of a rectangle are longer than each of its sides. We will therefore choose each of the edges B 1 and B 3 a little longer than each of the edges B 2 and B 4 .

A l'autre extrémité du corps tubulaire, on voit d'après la figure 9 que si les bords Cλ et C3 de la première et de la troisième régions il, 13 sont choisis égaux, ils sont nécessairement plus grands chacun que la moitié du bord C2 de la deuxième région puisque la somme de deux côtés C et C3 d'un triangle est toujours plus grande que le troisième côté C2. La quatrième région 14 a une longueur nulle ou quasi-nulle le long de cette extrémité du corps tubulaire, selon que le triangle constituant cette quatrième région est tronqué ou non. On a représenté par un agrandissement au bas de la figure 9 la configuration de repliement au bas de la région 14 lorsque celle-ci est constituée par un triangle tronqué. Lorsque le triangle n'est pas tronqué, le point de concourance 16 des lignes d'articulation 1 et 4 coïncide avec l'extrémité de celles-ci, comme illustré à la figure 5. Ainsi, le long de l'extrémité supérieure du corps tubulaire, on voit alterner les bords longs et courts, à savoir Bx (long) , B2 (court) , B3 (long) , et B (court) . Au contraire, le long de l'autre extrémité du corps tubulaire, deux bords courts C21 et C 2 (faisant partie du bord C2 de la deuxième région 12) , sont suivis de deux bords longs C3 et C .At the other end of the tubular body, it can be seen from FIG. 9 that if the edges C λ and C 3 of the first and third regions 11, 13 are chosen equal, they are necessarily larger each than half of the edge C 2 of the second region since the sum of two sides C and C 3 of a triangle is always greater than the third side C 2 . The fourth region 14 has a zero or almost zero length along this end of the tubular body, depending on whether the triangle constituting this fourth region is truncated or not. There is shown by an enlargement at the bottom of FIG. 9 the folding configuration at the bottom of the region 14 when the latter consists of a truncated triangle. When the triangle is not truncated, the point of concourance 16 of the articulation lines 1 and 4 coincides with the end of these, as illustrated in FIG. 5. Thus, along the upper end of the body tubular, we see alternating the long and short edges, namely B x (long), B 2 (short), B 3 (long), and B (short). On the contrary, along the other end of the tubular body, two short edges C 21 and C 2 (forming part of the edge C 2 of the second region 12), are followed by two long edges C 3 and C.

A titre d'exemple pratique, correspondant à un corps tubulaire ayant une longueur de 105 mm, on peut approximativement donner aux bords courts une longueur de 40 mm et aux bords longs une longueur de 41,5 mm. Les triangles dont la base est un bord court peuvent alors ne pas être tronqués, tandis que les triangles ayant pour base un bord long peuvent être tronqués de façon à avoir au sommet une largeur "S" (figure 5) égale à la différence de la longueur entre les bords longs et les bords courts, soit environ 1,5 mm dans l'exemple. On obtient ainsi deux avantages. D'une part toutes les lignes d'articulation du flan de la figure 5 sont parallèles à l'une ou à l'autre de deux directions et deux seulement, ce qui facilite grandement la fabrication. D'autre part, la largeur "S" des sommets des triangles tronqués, situés à certains angles de chaque extrémité du corps tubulaire, permet de réduire la surlongueur à donner aux bords longs. L'effet esthétique est donc amélioré aussi bien par l'égalité d'inclinaison des arêtes que par les faibles écarts de longueur entre bords longs et courts le long de chaque extrémité du corps tubulaire.As a practical example, corresponding to a tubular body having a length of 105 mm, one can approximately give the short edges a length of 40 mm and the long edges a length of 41.5 mm. The triangles whose base is a short edge can then not be truncated, while the triangles having for base a long edge can be truncated so as to have at the top a width "S" (Figure 5) equal to the difference of the length between the long edges and the short edges, approximately 1.5 mm in the example. Two advantages are thus obtained. On the one hand all the lines of articulation of the blank of Figure 5 are parallel to one or the other of two directions and only two, which greatly facilitates manufacturing. On the other hand, the width "S" of the vertices of the truncated triangles, located at certain angles of each end of the tubular body, makes it possible to reduce the extra length to give to the long edges. The aesthetic effect is therefore improved both by the equal inclination of the edges and by the small differences in length between long and short edges along each end of the tubular body.

On peut encore améliorer l'aspect en faisant en sorte que des biseaux soient présents à tous les angles, autrement dit que tous les triangles soient tronqués, d'une manière plus ou moins importante selon la longueur de leur base, toujours pour respecter le parallélisme de toutes les lignes d'articulation avec l'une ou l'autre de deux directions sur le flan.We can further improve the appearance by ensuring that bevels are present at all angles, in other words that all the triangles are truncated, in a more or less significant way according to the length of their base, always to respect the parallelism of all the lines of articulation with one or the other of two directions on the blank.

Selon un exemple particulièrement avantageux, les bords B2, B4, C21 et C22 ont une longueur de 40 mm chacun, les bords Bx et B3 une longueur de 41 mm, et les bords i et C3 une longueur de 42 mm. Chaque face triangulaire a un sommet tronqué dont la largeur est égale à la base du triangle en question, diminuée de 39 mm, ce qui donne un biseau de 1, 2 ou 3 mm selon les cas. Cette configuration a l'avantage que les deux extrémités du corps tubulaire à l'état mis en volume s'inscrivent dans un même cercle lorsqu'elles sont vues selon l'axe du corps. Le corps tubulaire apparaît strictement vertical lorsqu'il est posé par l'une de ses extrémités sur une surface horizontale.According to a particularly advantageous example, the edges B 2 , B 4 , C 21 and C 22 have a length of 40 mm each, the edges B x and B 3 a length of 41 mm, and the edges i and C 3 a length of 42 mm. Each triangular face has a truncated vertex whose width is equal to the base of the triangle in question, reduced by 39 mm, which gives a bevel of 1, 2 or 3 mm depending on the case. This configuration has the advantage that the two ends of the tubular body in the set state are in the same circle when viewed along the axis of the body. The tubular body appears strictly vertical when it is placed by one of its ends on a horizontal surface.

Les figures 10 à 13 illustrent le passage de 1'état plié de la figure 9 à l'état mis en volume de la figure 13, selon un processus similaire à celui décrit à propos de l'exemple des figures 1 à 3. Le pliage peut être déclenché en appuyant sur le repère 27 comme décrit précédemment.Figures 10 to 13 illustrate the transition from the folded state of Figure 9 to the volume state of Figure 13, according to a process similar to that described in connection with the example of Figures 1 to 3. Folding can be triggered by pressing the mark 27 as described above.

Au besoin, le corps tubulaire peut être transformé en contenant tel qu'une boîte ou un extérieur de vase au moyen d'un fond 29 (figure 13) conformé pour s'emboîter dans l'extrémité 26 du corps 3, et fermer cette extrémité. De même, la boîte peut être fermée supérieurement par un couvercle ayant une forme analogue au fond 29. Un fond ou un couvercle tel que 29 mais emboîtable extérieurement est également concevable. En même temps, de tels fonds ou couvercles stabilisent la forme du corps tubulaire mis en volume.If necessary, the tubular body can be transformed into a container such as a box or a vase exterior by means of a bottom 29 (FIG. 13) shaped to fit into the end 26 of the body 3, and close this end. . Similarly, the box can be closed at the top by a cover having a shape similar to the bottom 29. A bottom or a cover such as 29 but externally nestable is also conceivable. At the same time, such bottoms or covers stabilize the shape of the tubular body set in volume.

Les exemples des figures 14 à 25 ne seront décrits que pour leurs différences par rapport à celui des figures 5 à 13. Dans l'exemple des figures 14 et 15, toutes les faces sont triangulaires, aucun sommet n'est tronqué. Ceci oblige à prévoir une plus grande différence entre les bords longs Bx, B3, C1# C3 d'une part et les bords courts C21, C22, B2, B4 d'autre part. Par exemple, toujours pour un corps de 105 mm de long, les bords longs peuvent avoir une longueur d'environ 43 mm et les bords courts une longueur d'environ 40 mm. Ces écarts demeurent cependant difficilement décelables à l'oeil nu, qui perçoit la forme du corps tubulaire comme régulière. Indépendamment de ce qui précède, le corps tubulaire des figures 14 et 15 comporte, le long des bords C21, C22 et C3 des volets respectifs 36, 37, 38 pour réaliser un fond classique, c'est-à-dire non automatique. Le corps tubulaire forme ainsi, avec ces volets, une boîte à fond fermé et dessus ouvert.The examples of FIGS. 14 to 25 will only be described for their differences from that of FIGS. 5 to 13. In the example of FIGS. 14 and 15, all the faces are triangular, no vertex is truncated. This makes it necessary to provide for a greater difference between the long edges B x , B 3 , C 1 # C 3 on the one hand and the short edges C 21 , C 22 , B 2 , B 4 on the other hand. For example, still for a 105 mm long body, the long edges can be around 43 mm in length and the short edges around 40 mm in length. These differences remain difficult to detect with the naked eye, which perceives the shape of the tubular body as regular. Independently of the above, the tubular body of FIGS. 14 and 15 comprises, along the edges C 21 , C 22 and C 3 of the respective flaps 36, 37, 38 for producing a conventional bottom, that is to say not automatic. The tubular body thus forms, with these flaps, a box with closed bottom and open top.

Dans l'exemple des figures 16 et 17, le flan a une forme d'éventail, de façon que l'une des extrémités du corps tubulaire ait un périmètre bien plus grand que l'autre. Le corps tubulaire a ainsi l'aspect général d'un tronc de pyramide. De tels corps tubulaires sont mutuellement emboîtables. Là encore, une configuration quasi-régulière est réalisable grâce à une légère surlongueur des bords Bx et B3 par rapport aux bords B2 et B4, et des bords Qx et C3 par rapport aux bords C21 et C22.In the example of Figures 16 and 17, the blank has a fan shape, so that one end of the tubular body has a much larger perimeter than the other. The tubular body thus has the general appearance of a trunk of a pyramid. Such tubular bodies are mutually nestable. Here again, a quasi-regular configuration is possible thanks to a slight excess length of the edges B x and B 3 relative to the edges B 2 and B 4 , and of the edges Q x and C 3 relative to the edges C 21 and C 22 .

L'exemple des figures 18 et 19 est conforme à celui des figures 5 à 13 excepté que les bords Clf C21/ C22 et C3 sont munis de volets respectifs 31, 32, 33 et 34 pour réaliser un fond dit "automatique" bien connu du spécialiste de l'emballage. On réalise ainsi avec le corps tubulaire mis en volume et ledit fond une boîte à fond fermé et dessus ouvert représentée à la figure 19. Dans l'exemple des figures 20 et 21, les bords Bx, B2 et B3 sont prolongés respectivement par un rabat 39, un couvercle 41 et un rabat 42 pour permettre la fermeture supérieure de ce contenant. Celui-ci est destiné à constituer un vase de fleurs jetable. A cet effet, le couvercle 41 comporte un orifice 43 entouré par des languettes déformables 44 destinées à rassembler le bouquet comme représenté à la figure 22. Après formage du corps tubulaire à partir du flan comme cela est représenté aux figures 6 à 13, on fixe à l'intérieur du corps tubulaire un sac étanche ouvert à son extrémité supérieure. Cette fixation est réalisée par un collage 46 entre la face extérieure du sac et la face intérieure du corps tubulaire sur tout le pourtour à faible distance du bord supérieur du sac et des bords B1-B4 du corps tubulaire. Une fois ce collage réalisé en fabrication, on peut placer le vase en position pliée en exerçant une pression sur l'angle entre les bords B3 et B4 comme il a été dit précédemment. Le sac 45 ne s'oppose pas à ce pliage. Comme le sac 45 forme le fond du vase, le corps tubulaire est ouvert à son extrémité inférieure, pour simplifier au maximum l'opération de mise en volume.The example of Figures 18 and 19 is consistent with that of Figures 5 to 13 except that the edges C lf C 21 / C 22 and C 3 are provided with respective flaps 31, 32, 33 and 34 to achieve a bottom called "automatic "well known to the packaging specialist. Thus, with the tubular body set in volume and said bottom, a box with a closed bottom and an open top shown in FIG. 19 is produced. In the example of FIGS. 20 and 21, the edges B x , B 2 and B 3 are extended respectively by a flap 39, a cover 41 and a flap 42 to allow the upper closure of this container. This is intended to constitute a disposable flower vase. To this end, the cover 41 has an orifice 43 surrounded by deformable tongues 44 intended to bring together the bouquet as shown in FIG. 22. After forming the tubular body from the blank as shown in FIGS. 6 to 13, the device is fixed inside the tubular body a waterproof bag open at its upper end. This attachment is achieved by bonding 46 between the outer face of the bag and the inner face of the tubular body over the entire periphery at a short distance from the upper edge of the bag and the edges B 1 -B 4 of the tubular body. Once this bonding has been made during manufacture, the vase can be placed in the folded position by exerting pressure on the angle between the edges B 3 and B 4 as previously stated. The bag 45 does not oppose this folding. As the bag 45 forms the bottom of the vase, the tubular body is open at its lower end, to simplify the volume setting operation as much as possible.

Lors de l'achat d'un bouquet de fleurs, le fleuriste fournit, gratuitement ou contre supplément, le vase à l'état plié, la personne ayant acheté l'ensemble pouvant à son tour offrir le vase et le bouquet.When purchasing a bouquet of flowers, the florist provides the vase in the folded state, free of charge or at an additional cost, and the person who purchased the set can in turn offer the vase and bouquet.

Le sac 45 sert à contenir l'eau nécessaire pour la conservation du bouquet. Une fois les fleurs flétries, le vase pliable est jeté, de préférence à l'état plié pour minimiser l'encombrement dans la poubelle.The bag 45 serves to contain the water necessary for the conservation of the bouquet. Once the flowers have withered, the foldable vase is discarded, preferably in the folded state to minimize clutter in the trash can.

Dans l'exemple de la figure 23, le corps tubulaire 51 appartient à un récipient étanche dont le fond 52 est fermé par une paroi souple de même que l'extrémité supérieure 53, munie cependant d'un bouchon vissable 54. Le corps tubulaire 51 peut par exemple être réalisé en une matière à rigidité réduite le long des lignes d'articulation, par exemple une matière plastique ou métallique très malléable le long des articulations et nettement plus rigide en dehors des articulations. Avec cette réalisation, l'expulsion progressive du produit (lait concentré, dentifrice, crème d'entretien pour sol, pour chaussures, etc...), au lieu de s'effectuer par une déformation désordonnée d'un tube ou analogue, se fait de manière méthodique en commençant la compression sur le repère 27 et jusqu'à repliage complet de l'enveloppe. Ceci permet de vider très efficacement l'enveloppe sans avoir de grands efforts à effectuer même lorsque le produit s'épuise. L'extrémité du corps tubulaire qui est adjacente au repère 27 est placée à l'opposé de la paroi souple munie du bouchon 53. Ainsi, la compression progressive du récipient étanche commence par l'extrémité opposée à l'orifice d'éjection du produit.In the example of Figure 23, the tubular body 51 belongs to a sealed container whose bottom 52 is closed by a flexible wall as well as the upper end 53, however provided with a screw cap 54. The tubular body 51 may for example be made of a material with reduced rigidity along the articulation lines, for example a plastic material or metallic very malleable along the joints and much more rigid outside the joints. With this embodiment, the gradual expulsion of the product (concentrated milk, toothpaste, maintenance cream for floors, for shoes, etc.), instead of being carried out by a disorderly deformation of a tube or the like, done in a methodical way by starting the compression on the mark 27 and until complete folding of the envelope. This allows the envelope to be emptied very efficiently without having to make great efforts even when the product runs out. The end of the tubular body which is adjacent to the reference 27 is placed opposite the flexible wall provided with the plug 53. Thus, the progressive compression of the sealed container begins at the end opposite the product ejection orifice .

Dans l'exemple de la figure 24 le corps tubulaire 61, par exemple réalisé en carton, serre simplement d'enveloppe périphérique pour une poche étanche 62 en matière plastique, dont l'extrémité supérieure est destinée à être coupée ou déchirée pour libérer le produit. Là encore, le corps tubulaire 61 va aider à comprimer rationnellement la poche 62 pour expulser le produit, en commençant par l'extrémité éloignée de 1'ouverture. Dans l'exemple de la figure 25, les lignes d'articulation, au lieu d'être réalisées par de simples rainages d'un flan en carton par exemple, ont une certaine largeur L. Elles sont constituées par un voile de matière souple réunissant les faces proprement dites, qui sont plus épaisses et quasiment rigides. Ceci facilite la fabrication car toutes les faces peuvent être constituées par des triangles identiques, tronqués ou non. Les écarts de longueur nécessaires pour le pliage sont fournis par la matière souple, qui à l'état plié du corps s'aligne avec les faces dont la dimension doit être plus grande. L'utilisation est également facilitée car le pliage peut être déclenché en appuyant sur n'importe quel sommet de face triangulaire. Bien entendu l'invention n'est pas limitée aux exemples décrits et représentés.In the example of FIG. 24, the tubular body 61, for example made of cardboard, simply squeezes a peripheral envelope for a sealed pocket 62 of plastic material, the upper end of which is intended to be cut or torn to release the product. . Again, the tubular body 61 will help to rationally compress the bag 62 to expel the product, starting at the end remote from the opening. In the example of FIG. 25, the articulation lines, instead of being produced by simple creasing of a cardboard blank, for example, have a certain width L. They consist of a veil of flexible material uniting the faces themselves, which are thicker and almost rigid. This facilitates manufacturing because all the faces can be constituted by identical triangles, truncated or not. The length differences necessary for folding are provided by the flexible material, which in the folded state of the body aligns with the faces whose dimension must be greater. The use is also facilitated because the folding can be triggered by pressing on any triangular face vertex. Of course, the invention is not limited to the examples described and shown.

Il n'est pas nécessaire que la hauteur du corps tubulaire soit la même tout le long de sa périphérie. Par rapport à l'exemple de la figure 4, on pourrait par exemple prévoir au moins une arête supplémentaire sur la deuxième région latérale et aucune sur les trois autres régions. L'invention n'exclut pas non plus la présence de lignes d'articulation sur la quatrième région latérale. Dans le cas de faces toutes identiques ou similaires, leur forme peut être trapézoïdale au lieu de triangulaire par exemple.The height of the tubular body need not be the same all along its periphery. Compared to the example in FIG. 4, one could for example provide at least one additional edge on the second lateral region and none on the other three regions. The invention also does not exclude the presence of articulation lines on the fourth lateral region. In the case of all identical or similar faces, their shape can be trapezoidal instead of triangular for example.

Les nombres de faces supérieurs à huit sont concevables. On peut réaliser le corps tubulaire à partir d'un tube de matière, au lieu de partir d'un flan. On peut réaliser l'invention directement par moulage.The numbers of faces greater than eight are conceivable. The tubular body can be produced from a tube of material, instead of from a blank. The invention can be carried out directly by molding.

Dans le cas d'un corps tubulaire évasé vers l'une de ses extrémités, il n'est pas indispensable que la deuxième et la quatrième région latérale se rétrécissent en sens opposés.In the case of a tubular body flared towards one of its ends, it is not essential that the second and the fourth lateral region shrink in opposite directions.

Il est notamment possible de combiner librement, autrement que décrit, les structures de corps tubulaires décrites, avec les moyens de fermeture totale ou partielle, inférieure ou supérieure décrits et/ou avec les moyens d'étanchéité décrits. It is in particular possible to freely combine, otherwise than described, the tubular body structures described, with the total or partial closing means, lower or upper described and / or with the sealing means described.
