Definitions
- the present invention relates to a new folding box structure with curved faces, which can be stored flat and capable of being shaped by simple manual pressure on the deformable sides.
- the object of the invention is to propose a box structure allowing an easy production and storage, the box being in the folded and flat state, and a shaping no less easy without carrying out any mounting or joining of elements. any of the box.
- the object of the invention is also to propose a particular version of box fulfilling the above requirements and capable of constituting a cup which, once in shape, can be placed upright on a flat horizontal surface.
- Such a structure is relatively complex, not very economical in material due to the provision of the folding parts which extend from the top to the bottom of the cup and over practically its entire width and the stability of the cup is precarious due to the instability of the parts. folded down with free ends.
- the method of folding and shaping the cup does not allow a wide and stable opening and prohibits any printing for example of an advertising message on the visible faces of the cup once in shape since these faces are in contact with the food content of the cup when it is not open.
- a tetrahedral box which can be stored flat, but which has no curved faces, the configuration being such that it cannot pass from the flat position to the position in volume, without the box being in the open position.
- the invention aims to improve these known structures and to eliminate the drawbacks mentioned.
- the subject of the invention is a folding box with curved faces, storable empty flat and shaped by simple pressure, consisting, flat, of two sheets facing each other and of the same dimensions, of polygonal outline , sealingly contiguous on all sides of said polygonal contour except one and in which, in line with at least one of said contiguous sides, the two sheets comprise two arcuate creasing lines, superimposed, ending at the ends, or at in the vicinity of the ends, of the junction line of the sheets delimiting said contiguous side, the shaping of the box being effected by pressing towards the center of the box in the middle of the contiguous side or sides provided with said creasing lines, characterized in that that the sheets extend beyond at least one joined side by a strip where the sheets are joined, said strip, during the depression of the middle of said side for the shaping of the a box, folding against the concave face thus formed.
- said contour is rectangular, square or trapezoidal, the contiguous sides, except that opposite to the non-contiguous side, being provided with said creasing lines, the extensions beyond said contiguous sides of said sheets having a rim in the extension of the end edge associated with said contiguous side not provided with creasing lines and extending over a distance sufficient to delimit with said end edge, after folding against the concave faces of the cup, a support polygon for placing the cup in standing form on a flat horizontal surface.
- one of the sheets is made of cardboard and the other sheet is a sheet of preformed plastic material which is preferably transparent, the cardboard possibly being treated as a whole or on its face facing the another sheet so as to allow the connection between the two sheets by welding to the right of said contiguous sides and their possible extensions.
- the box shown flat in Figure 1 comprises two sheets 1a and 1b of rectangular cardboard, of the same dimensions and superimposed.
- the two sheets consist of a single sheet folded back on itself along a line 2.
- Lines 2, 3 and 4 define a rectangular outline, the fourth side of which, symbolized by FIG. 5, is said to be non-contiguous in the sense that the opposite parts of the two sheets can, at this point, move apart to give access to the interior of the box.
- the two sheets are extended by forming overlapping strips 6, 7 and 8 respectively.
- the strips 6 and 7 corresponding to lines 3 and 4 are joined together over their entire surface, while the strips 8 are not and can be opened, giving access to the inside of the box.
- Each sheet 1a, 1b comprises four arcuate creasing lines 9, 10, 11 and 12, in line with the four lines or sides 2 to 5 respectively.
- the arcuate lines 9 and 12 respectively connect the ends of the associated sides 2 and 5, while the arcuate lines 10 and 11 join the sides 3 and 4 respectively at some distance from their ends.
- the two sheets 1a, 1b are identically grooved, the lines 9 to 12 being thus superimposed but not joined so that the box can be shaped as shown in Figures 2 and 3 by pressing in the middle of the sides 2,3 and 4 to push these towards the center of the box.
- the box is thus given the general shape of a carton with two convex star-shaped faces with four branches delimited by the sheets 1a and 1b, between the arched lines 9 to 12 and three concave side faces designated by the references 13 , 14 and 15 in Figure 2.
- the narrow side strips 6 and 7 are curved and fold down by pressing against the faces 14 and 15 thus marrying their concavity. Their role is to serve as stiffening ribs and to maintain the formed position of the box.
- means for closing the box which may vary in their nature. It may be a closure by sealing or welding along the side 5 or to the right of the strips 8 or any system allowing at will the opening and closing of the box.
- the side 2 can be extended by strips for securing the two sheets, similar to strips 6 and 7.
- the two sheets 1a, 1b are made of the same material or not. When they are different, one may be made of plastic, preferably transparent, and the other of cardboard treated as a whole or on its face facing the plastic sheet to allow the two sheets to be welded in line with the contiguous sides (2,3,4) and any bands (6,7) adjacent to these sides.
- Such a box advantageously serves as packaging for the presentation and sale of all kinds of unitary or bulk products, food or not, which can be perfectly observed through the transparent plastic sheet if such a sheet is provided.
- the berlingot shape is a harmonious shape and the convex faces of the box lend themselves easily to all kinds of aesthetic and / or informative impressions.
- FIGS. 1 to 3 are perfectly suitable for packaging on display stands with hanging rods.
- the arcuate lines 12 of the two sheets 1a, 1b can be deleted if necessary.
- the polygonal contour formed by the contiguous sides such as 2,3 and 4 and the non-contiguous side such as 5, can be any, the number of sides being equal to or greater than three, with at least one of the sides can be opened to access the inside of the box.
- the pairs of arcuate lines are arranged in line with at least one of the contiguous sides, all of the latter being able to be provided with them as illustrated in FIG. 1.
- Figures 4 to 6 illustrate an alternative embodiment according to which only one of the contiguous sides, that (17) affixed to the opening side of the box, is provided with arcuate lines 18 on the two constituent sheets 1′a, 1′b of the box.
- Figure 4 it is a box whose outline, flat, is rectangular with two adjoining lateral sides 19 and 20 not provided with arcuate lines.
- the three contiguous sides 17,19,20 are extended by narrow bands 21 to 23 similar to bands 6 and 7 of the figure 1.
- arcuate lines 18 extend beyond the ends of the side 17 as far as in the external corner of the connection zone of the adjacent strips 21,22,23.
- One of the sheets (1′a) is, for example, of transparent plastic, of the type used for the blister, while the other sheet (1′b) is made of treated cardboard to allow the sheets to be welded at right sides 17,19,20 and peripheral bands 21,22,23.
- the box is closed by two flaps 24 in the form of a biconvex lens, superimposed when the box is flat, and folded against one another in the formed position of the box so as to completely block its orifice.
- this system is also well known. Said flaps 24 are separated from the body of the box by arcuate lines 25.
- the contiguous sides 19 and 20 could of course be provided with arcuate lines analogous to lines 10 and 11 in FIG. 1, the box thus formed would then have the shape of a real carton, with four concave side faces.
- Figures 7 to 9 illustrate an alternative embodiment of the box according to the invention intended to serve as a cup once shaped.
- the two sheets 1 ⁇ a and 1 ⁇ b are, for example, square in shape and linked together along the lines 26, 27 and 28 as well as in line with the strips 29 adjacent to the side 26, and two triangular extensions 30 and 31 associated with lines 27 and 28.
- the non-contiguous edges 32 are extended by strips 33 which can move apart to give access to the interior of the cup once the latter has been shaped (FIGS. 8 and 9).
- the two opposite contiguous sides 27 and 28 are associated with arcuate lines 34 and 35 extending to the ends of the sides 27 and 28.
- the sheet 1 ⁇ a preferably has a rigidity greater than that of the sheet 1b in order to have a preferential folding of the triangular parts 30 and 31 against the part of the sheet 1 ⁇ b between the side 28 and the line 35 of this last sheet.
- the particular shape of the triangular parts 30 and 31 is determined so that the lower edges 30a and 31a are of sufficient length so that once folded substantially at 90 ° from the bands 29, they determine with the latter a support polygon allowing the cup , once in shape (Figure 9), to stand with its substantially horizontal upper orifice.
- the shaped cup has two concave flanks 36 and 37 (FIG. 8) similar to the two lateral flanks 14 and 15 of the box in FIG. 2.

Description
La présente invention a trait à une nouvelle structure de boîte pliante à faces incurvées, pouvant être stockée à plat et susceptible d'être mise en forme par simple pression manuelle sur les côtés déformables.The present invention relates to a new folding box structure with curved faces, which can be stored flat and capable of being shaped by simple manual pressure on the deformable sides.
Le but de l'invention est de proposer une structure de boîte permettant une réalisation et un stockage faciles, la boîte étant à l'état pliée et à plat, et une mise en forme non moins facile sans effectuer aucun montage ou solidarisation d'éléments quelconques de la boîte.The object of the invention is to propose a box structure allowing an easy production and storage, the box being in the folded and flat state, and a shaping no less easy without carrying out any mounting or joining of elements. any of the box.
Le but de l'invention est également de proposer une version particulière de boîte remplissant les desiderata ci-dessus et apte à constituer un gobelet pouvant, une fois en forme, être posé debout sur une surface plane horizontale.The object of the invention is also to propose a particular version of box fulfilling the above requirements and capable of constituting a cup which, once in shape, can be placed upright on a flat horizontal surface.
Par le document EP-A-290 356, pour ce qui concerne le contenu du document de priorité FR-A-2 614873, qui constitue un art antérieur au sens de l'article 54 (3) CBE, on connaît une structure de gobelet pliable à faces incurvées stockable à vide à plat et à mise en forme par simple pression, les parois du gobelet étant prolongées en partie supérieure pour former des parties rabattables définissant par leurs extrémités un polygone de sustentation pour le gobelet.By document EP-A-290 356, as regards the content of priority document FR-A-2 614873, which constitutes a prior art within the meaning of article 54 (3) EPC, a cup structure is known foldable with curved faces which can be stored empty flat and which can be shaped by simple pressure, the walls of the cup being extended at the top to form foldable parts defining at their ends a support polygon for the cup.
Une telle structure est relativement complexe, peu économe de matière du fait de la prévision des parties rabattables qui s'étendent du haut en bas du gobelet et sur pratiquement toute sa largeur et la stabilité du gobelet est précaire du fait de l'instabilité des parties rabattues dont les extrémités sont libres.Such a structure is relatively complex, not very economical in material due to the provision of the folding parts which extend from the top to the bottom of the cup and over practically its entire width and the stability of the cup is precarious due to the instability of the parts. folded down with free ends.
En outre, le mode de pliage et mise en forme du gobelet n'autorise pas une ouverture large et stable et interdit toute impression par exemple d'un message publicitaire sur les faces visibles du gobelet une fois en forme puisque ces faces sont au contact avec le contenu alimentaire du gobelet lorsque celui-ci n'est pas ouvert.In addition, the method of folding and shaping the cup does not allow a wide and stable opening and prohibits any printing for example of an advertising message on the visible faces of the cup once in shape since these faces are in contact with the food content of the cup when it is not open.
Par ailleurs, par le document DE-B-1.105.701 on connaît une boîte tétraédrique et stockable à plat, mais quine comporte pas de faces incurvées, la configuration étant telle qu'elle ne peut passer de la position à plat à la position en volume, sans que la boîte soit en position ouverte.Furthermore, from document DE-B-1.105.701 a tetrahedral box is known which can be stored flat, but which has no curved faces, the configuration being such that it cannot pass from the flat position to the position in volume, without the box being in the open position.
L'invention vise à perfectionner ces structures connues et à éliminer les inconvénients cités.The invention aims to improve these known structures and to eliminate the drawbacks mentioned.
A cet effet, l'invention a pour objet une boîte pliante à faces incurvées, stockable à vide à plat et à mise en forme par simple pression, constituée, à plat, de deux feuilles se faisant face et de mêmes dimensions, de contour polygonal, jointives de manière étanche sur tous les côtés dudit contour polygonal sauf un et dans laquelle, au droit d'au moins l'un desdits côtés jointifs, les deux feuilles comportent deux lignes de rainage arquées, superposées, se terminant aux extrémités, ou au voisinage des extrémités, de la ligne de jonction des feuilles délimitant ledit côté jointif, la mise en forme de la boîte s'effectuant par enfoncement vers le centre de la boîte du milieu du ou des côtés jointifs munis desdites lignes de rainage, caractérisée en ce que les feuilles se prolongent au delà d'au moins un côté jointif par une bande où les feuilles sont solidarisées, ladite bande, au cours de l'enfoncement du milieu dudit côté pour la mise en forme de la boîte, se rabattant contre la face concave ainsi constituée.To this end, the subject of the invention is a folding box with curved faces, storable empty flat and shaped by simple pressure, consisting, flat, of two sheets facing each other and of the same dimensions, of polygonal outline , sealingly contiguous on all sides of said polygonal contour except one and in which, in line with at least one of said contiguous sides, the two sheets comprise two arcuate creasing lines, superimposed, ending at the ends, or at in the vicinity of the ends, of the junction line of the sheets delimiting said contiguous side, the shaping of the box being effected by pressing towards the center of the box in the middle of the contiguous side or sides provided with said creasing lines, characterized in that that the sheets extend beyond at least one joined side by a strip where the sheets are joined, said strip, during the depression of the middle of said side for the shaping of the a box, folding against the concave face thus formed.
Suivant une application particulière de la structure selon l'invention à l'obtention d'un gobelet, ledit contour est rectangulaire, carré ou trapézoïdal, les côtés jointifs , hormis celui opposé au côté non jointif, étant munis desdites lignes de rainage, les prolongements au delà desdits côtés jointifs desdites feuilles présentant un rebord dans le prolongement du bord extrême associé audit côté jointif non pourvu de lignes de rainage et s'étendant sur une distance suffisante pour délimiter avec ledit bord extrême, après rabattage contre les faces concaves du gobelet, un polygone de sustentation permettant de poser le gobelet en forme debout sur une surface plane horizontale.According to a particular application of the structure according to the invention for obtaining a cup, said contour is rectangular, square or trapezoidal, the contiguous sides, except that opposite to the non-contiguous side, being provided with said creasing lines, the extensions beyond said contiguous sides of said sheets having a rim in the extension of the end edge associated with said contiguous side not provided with creasing lines and extending over a distance sufficient to delimit with said end edge, after folding against the concave faces of the cup, a support polygon for placing the cup in standing form on a flat horizontal surface.
Suivant encore un autre mode de mise en oeuvre, l'une des feuilles est en carton et l'autre feuille est une feuille de matière plastique préformée de préférence transparente, le carton étant éventuellement traité dans sa masse ou sur sa face tournée vers l'autre feuille de façon à permettre la liaison entre les deux feuilles par soudage au droit desdits côtés jointifs et de leurs éventuels prolongements.According to yet another mode of implementation, one of the sheets is made of cardboard and the other sheet is a sheet of preformed plastic material which is preferably transparent, the cardboard possibly being treated as a whole or on its face facing the another sheet so as to allow the connection between the two sheets by welding to the right of said contiguous sides and their possible extensions.

La boîte représentée à plat sur la figure 1 comprend deux feuilles 1a et 1b de carton rectangulaire, de mêmes dimensions et superposées.The box shown flat in Figure 1 comprises two
Plus précisément, dans le mode de réalisation représenté, les deux feuilles sont constituées par une seule et même feuille repliée sur elle-même le long d'une ligne 2.More specifically, in the embodiment shown, the two sheets consist of a single sheet folded back on itself along a
Les deux feuilles sont solidarisées entre elles, outre le long de ladite ligne 2, le long de deux lignes 3 et 4 parallèles entre elles et perpendiculaires à la ligne 2. Les lignes 2, 3 et 4 délimitent un contour rectangulaire dont le quatrième côté, symbolisé par la figure 5, est dit non jointif en ce sens que les parties en regard des deux feuilles peuvent, à cet endroit, s'écarter pour donner accès à l'intérieur de la boîte.The two sheets are joined together, in addition to along said
Au-delà des lignes 3, 4 et 5 les deux feuilles se prolongent en formant des bandes superposées respectivement 6, 7 et 8. Les bandes 6 et 7 correspondant aux lignes 3 et 4 sont solidarisées entre elles sur toute leur surface, cependant que les bandes 8 ne le sont pas et peuvent s'ouvrir, donner accés à l'intérieur de la boîte.Beyond
Chaque feuille 1a,1b comporte quatre lignes de rainage arquées 9,10,11 et 12, au droit des quatre lignes ou côtés 2 à 5 respectivement.Each
Les lignes arquées 9 et 12 relient respectivement les extrémités des côtés 2 et 5 associés, cependant que les lignes arquées 10 et 11 rejoignent les côtés 3 et 4 respectivement à quelque distance de leurs extrémités.The
Les deux feuilles 1a,1b sont rainées identiquement, les lignes 9 à 12 étant ainsi superposées mais non solidarisées de façon que la boîte puisse être mise en forme comme représentée aux figures 2 et 3 par pression au milieu des côtés 2,3 et 4 pour enfoncer ces derniers vers le centre de la boîte.The two
On donne ainsi à la boîte la forme générale d'un berlingot avec deux faces convexes en forme d'étoile à quatre branches délimitées par les feuilles 1a et 1b, entre les lignes arquées 9 à 12 et trois faces latérales concaves désignées par les références 13,14 et 15 sur la figure 2.The box is thus given the general shape of a carton with two convex star-shaped faces with four branches delimited by the
Ces faces concaves sont formées par la mise dans le prolongement et dans le même plan des parties homologues en regard des deux feuilles 1a,1b, en forme de cordes d'arc, telles que 16a et 16b sur les figures 1 et 3, délimitées entre lesdits côtés 2,3 et 4 et les lignes arquées associées 9,10 et 11 respectivement.These concave faces are formed by placing in the extension and in the same plane of the homologous parts opposite the two
Les bandes étroites latérales 6 et 7 se trouvent cintrées et se rabattent en se plaquant contre les faces 14 et 15 épousant ainsi leur concavité. Leur rôle est de servir de nervures de rigidification et de maintien en position formée de la boîte.The
Au niveau des côtés et bandes 5 et 8 sont prévus des moyens (non représentés) de fermeture de la boîte pouvant varier dans leur nature. Il peut s'agir d'une fermeture par scellement ou soudage le long du côté 5 ou au droit des bandes 8 ou d'un système quelconque permettant à volonté l'ouverture et la fermeture de la boîte.At the sides and
Dans le cas des deux feuilles 1a,1b totalement séparées, le côté 2 peut être prolongé par des bandes de solidarisation des deux feuilles, analogues aux bandes 6 et 7.In the case of the two completely separated
Les deux feuilles 1a,1b sont en même matière ou non. Lorsau'elles sont différentes, l'une peut être en matière plastique, de préférence transparente, et, l'autre en carton traîté dans sa masse ou sur sa face tournée vers la feuille en plastique pour permettre le soudage des deux feuilles au droit des côtés jointifs (2,3,4) et des éventuelles bandes (6,7) adjacentes à ces côtés.The two
Une telle boîte sert avantageusement de conditionnement pour la présentation et la vente de toutes sortes de produits unitaires ou en vrac, alimentaires ou non, que l'on peut parfaitement observer à travers la feuille plastique transparente si une telle feuille est prévue.Such a box advantageously serves as packaging for the presentation and sale of all kinds of unitary or bulk products, food or not, which can be perfectly observed through the transparent plastic sheet if such a sheet is provided.
La forme de berlingot est une forme harmonieuse et les faces convexes de la boîte se prêtent aisément à toute sorte d'impressions esthétiques et/ou informatives.The berlingot shape is a harmonious shape and the convex faces of the box lend themselves easily to all kinds of aesthetic and / or informative impressions.
Les boîtes telles qu'illustrées par les figures 1 à 3 conviennent parfaitement pour des conditionnements sur des présentoirs à tringles de suspension.The boxes as illustrated in FIGS. 1 to 3 are perfectly suitable for packaging on display stands with hanging rods.
Les lignes arquées 12 des deux feuilles 1a,1b peuvent être supprimées le cas échéant.The
D'une manière générale, le contour polygonal formé par les côtés jointifs tels que 2,3 et 4 et le côté non jointifs tel que 5, peut être quelconque, le nombre des côtés étant égal ou supérieur à trois, avec au moins un des côtés susceptible d'être ouvert pour accéder à l'intérieur de la boîte.In general, the polygonal contour formed by the contiguous sides such as 2,3 and 4 and the non-contiguous side such as 5, can be any, the number of sides being equal to or greater than three, with at least one of the sides can be opened to access the inside of the box.
Les paires de lignes arquées sont ménagées au droit d'au moins un des côtés jointifs, la totalité de ces derniers pouvant en être munis comme illustré par la figure 1.The pairs of arcuate lines are arranged in line with at least one of the contiguous sides, all of the latter being able to be provided with them as illustrated in FIG. 1.
Les figures 4 à 6 illustrent une variante de réalisation selon laquelle un seul des côtés jointifs, celui (17) apposé au côté d'ouverture de la boîte, est muni de lignes arquées 18 sur les deux feuilles constitutives 1′a,1′b de la boîte.Figures 4 to 6 illustrate an alternative embodiment according to which only one of the contiguous sides, that (17) affixed to the opening side of the box, is provided with
Sur la figure 4, il s'agit d'une boîte dont le contour, à plat, est rectangulaire avec deux côtés latéraux jointifs 19 et 20 non munis de lignes arquées.In Figure 4, it is a box whose outline, flat, is rectangular with two adjoining
Les trois côtés jointifs 17,19,20 sont prolongés par des bandes étroites 21 à 23 analogues aux bandes 6 et 7 de la figure 1.The three
Il est à noter que les lignes arquées 18 se prolongent au delà des extrémités du côté 17 jusque dans l'angle externe de la zone de raccordement des bandes adjacentes 21,22,23.It should be noted that the
L'une des feuilles (1′a) est, par exemple, en matière plastique transparente, du type utilisé pour le blister, cependant que l'autre feuille (1′b) est en carton traité pour permettre le soudage des feuilles au droit des côtés 17,19,20 et des bandes périphériques 21,22,23.One of the sheets (1′a) is, for example, of transparent plastic, of the type used for the blister, while the other sheet (1′b) is made of treated cardboard to allow the sheets to be welded at
Au niveau du côté non jointif la boîte est fermée par deux volets 24 en forme de lentille biconvexe, superposés lorsque la boîte est à plat, et rabattus l'un contre l'autre en position formée de la boîte de manière à obturer totalement son orifice d'entrée (figure 6), ce système étant par ailleurs bien connu. Lesdits volets 24 sont séparés du corps de la boîte par des lignes arquées 25.At the non-contiguous side, the box is closed by two
Il est à noter que lors de la mise en forme de la boîte, du fait des différences de rigidité entre les matériaux des deux feuilles 1′a et 1′b, les bandes périphériques 21 à 23 ont tendance à se rabattre préférentiellement en direction de la feuille de carton 1′b, ce qui facilite la mise en forme et rigidifie la structure tridimensionnelle ainsi constituée.It should be noted that during the shaping of the box, due to the differences in rigidity between the materials of the two sheets 1′a and 1′b, the
Les côtés jointifs 19 et 20 pourraient bien entendu être munis de lignes arquées analogues aux lignes 10 et 11 de la figure 1, la boîte ainsi formée aurait alors la forme d'un véritable berlingot, avec quatre faces latérales concaves.The contiguous sides 19 and 20 could of course be provided with arcuate lines analogous to
Les figures 7 à 9 illustrent une variante de réalisation de la boîte selon l'invention destinée à servir de gobelet une fois mise en forme.Figures 7 to 9 illustrate an alternative embodiment of the box according to the invention intended to serve as a cup once shaped.
A cet effet, les deux feuilles 1˝a et 1˝b sont, par exemple, de forme carrée et liées entre elles le long des lignes 26,27 et 28 ainsi qu'au droit des bandes 29 adjacentes au côté 26, et de deux prolongements triangulaires 30 et 31 associés aux lignes 27 et 28.For this purpose, the two sheets 1˝a and 1˝b are, for example, square in shape and linked together along the
Les bords non jointifs 32 sont prolongés par des bandes 33 qui peuvent s'écarter pour donner accès à l'intérieur du gobelet une fois celui-ci mis en forme (figures 8 et 9).The non-contiguous edges 32 are extended by
Aux deux côtés jointifs opposés 27 et 28 sont associées des lignes arquées 34 et 35 s'étendant jusqu'aux extrémités des côtés 27 et 28.The two opposite
La feuille 1˝a présente de préférence une rigidité supérieure à celle de la feuille 1 b afin d'avoir un pliage préférentiel des parties triangulaires 30 et 31 contre la partie de la feuille 1˝b comprise entre le côté 28 et la ligne 35 de cette dernière feuille.The sheet 1˝a preferably has a rigidity greater than that of the
La forme particulière des parties triangulaires 30 et 31 est déterminée de façon que les bords inférieurs 30a et 31a soient de longueur suffisante pour qu'une fois rabattus sensiblement à 90° des bandes 29, ils déterminent avec ces dernières un polygone de sustentation permettant au gobelet, une fois en forme (figure 9), de tenir debout avec son orifice supérieur sensiblement horizontal.The particular shape of the
Le gobelet en forme présente deux flancs concaves 36 et 37 (figure 8) analogues aux deux flancs latéraux 14 et 15 de la boîte de la figure 2.The shaped cup has two
On peut, bien entendu, jouer sur la forme du gobelet en modifiant la longueur du côté 26. C'est ainsi qu'on peut lui donner une même longueur que le côté 32, en conservant aux parties triangulaires 30 et 31 les mêmes dimensions pour des questions de stabilité du gobelet, le contour général des feuilles 1˝a et 1˝b étant alors non plus carré mais trapézoïdal avec la grande base en partie inférieure.We can, of course, play on the shape of the cup by changing the length of the
