Description

Récipient à section évolutive entre un contour carré et un contour rectangulaire  Container with an evolutionary section between a square outline and a rectangular outline
L'invention a trait au domaine des récipients en matière thermoplastique tel que PET, et plus particulièrement, bien que non exclusivement, les récipients, tels que les bouteilles, pouvant être remplis à chaud. The invention relates to the field of thermoplastic containers such as PET, and more particularly, although not exclusively, the containers, such as bottles, which can be filled hot.
Un récipient est généralement fabriqué par soufflage ou étirage soufflage d'une préforme injectée, laquelle est d'abord chauffée au défilé dans un four muni d'éléments de chauffe par rayonnement, puis introduite chaude dans un moule muni d'une cavité définissant la contre-empreinte du récipient.  A container is generally manufactured by blow molding or stretch blow molding of an injected preform, which is first heated on the run in a furnace equipped with radiant heating elements, then introduced hot into a mold provided with a cavity defining the counterweight. -print of the container.
A titre indicatif, la température du liquide lors d'un remplissage à chaud dépasse fréquemment 60°C, et atteint couramment 90°C à 95°C (soit une température supérieure à la température de transition vitreuse du PET).  As an indication, the temperature of the liquid during a hot filling frequently exceeds 60 ° C, and commonly reaches 90 ° C to 95 ° C (ie a temperature above the glass transition temperature of PET).
Un récipient ordinaire offre une tenue mécanique insuffisante qui, lors d'un remplissage à chaud, se traduirait par des déformations importantes résultant du choc thermique qui accompagne un tel remplissage. En outre, lors du refroidissement ultérieur du contenu, le récipient se déformerait encore, en raison de la dépression interne accompagnant la diminution de la température.  An ordinary container has an insufficient mechanical strength which, during hot filling, would result in significant deformations resulting from the thermal shock that accompanies such a filling. In addition, during the subsequent cooling of the contents, the container would deform further, due to the internal depression accompanying the decrease in temperature.
Aussi les récipients destinés au remplissage à chaud (dénommés HR, acronyme de l'expression anglaise « heat résistant ») bénéficient- ils d'une fabrication adaptée et de dispositions structurelles particulières les rendant moins sensibles aux déformations et leur permettant de conserver durablement leur forme générale.  Also the containers for hot filling (called HR, acronym for the expression "heat resistant") benefit from a suitable manufacturing and special structural provisions making them less sensitive to deformations and allowing them to maintain their shape for a long time. General.
On prévoit en général sur le récipient des zones déformables à déformation contrôlée. Ainsi, il est connu de munir le corps du récipient de panneaux qui, lors du remplissage, vont se bomber sous l'effet combiné de la température et de la pression hydrostatique, et qui, lorsque le liquide va refroidir, vont, à l'inverse, se rétracter pour accompagner la réduction du volume de liquide.  The container is generally provided with deformable zones with controlled deformation. Thus, it is known to provide the container body panels which, during filling, will bulge under the combined effect of temperature and hydrostatic pressure, and which, when the liquid will cool, go to the reverse, retract to accompany the reduction of the volume of liquid.
On connaît ainsi des récipients à section approximativement carrée, munis de panneaux reliés par des facettes légèrement bombées, disposées aux quatre coins du carré, et destinées à se déformer par aplatissement pour absorber la dépression accompagnant le refroidissement du contenu, cf. par ex. le brevet américain US 7 699 183 (COCA COLA). Containers of approximately square cross-section are thus known, provided with panels connected by slightly convex facets arranged at the four corners of the square and intended to deform by flattening to absorb the accompanying depression. the cooling of the contents, cf. eg. US Pat. No. 7,699,183 (COCA COLA).
Si, en théorie, la déformation du récipient est contrôlée, on constate dans la pratique que tel n'est pas le cas. En effet, le récipient a tendance à se déformer d'une manière globale, s'aplatissant depuis sa forme initialement carrée vers une forme en losange dans laquelle les angles entre les panneaux ne sont plus droits. Il en résulte un défaut de rigidité du récipient lors de la prise en main. Ce défaut tend à s'aggraver avec la diminution de la quantité de matière employée (ce qui est la tendance générale actuelle chez les fabricants de récipients, essentiellement pour des raisons de coût et d'évolution des normes anti-pollution).  If, in theory, the deformation of the container is controlled, it is found in practice that this is not the case. Indeed, the container tends to deform in a global manner, flattening from its initially square shape to a diamond shape in which the angles between the panels are no longer right. This results in a lack of rigidity of the container when taken in hand. This defect tends to worsen with the decrease in the amount of material used (which is the current general trend among container manufacturers, mainly for reasons of cost and evolution of anti-pollution standards).
On constate en outre que cette déformation est d'autant plus grande dans à mi-hauteur du corps.  It is further noted that this deformation is all the greater in mid-height of the body.
Diverses solutions existent pour remédier à ce problème.  Various solutions exist to remedy this problem.
Une première solution, évidente, consiste à augmenter l'épaisseur du récipient.  A first, obvious solution is to increase the thickness of the container.
Une deuxième solution consiste à munir le récipient d'une ceinture, cf. par ex. la demande de brevet européen EP 2 473413 (SIDEL PARTICIPATIONS).  A second solution is to provide the container with a belt, cf. eg. European Patent Application EP 2 473413 (SIDEL PARTICIPATIONS).
Mais ces solutions nécessitent toutes deux un surcroît de matière pour la fabrication du récipient, ce qui est contraire aux cahiers des charges actuels, qui requièrent au contraire une diminution de la quantité de matière employée.  But these solutions both require an additional material for the manufacture of the container, which is contrary to current specifications, which require on the contrary a decrease in the amount of material used.
Un premier objectif est de proposer un récipient offrant une meilleure résistance aux déformations, notamment dues à une dépression accompagnant le refroidissement du contenu lorsque celui- ci a été introduit à chaud.  A first objective is to provide a container with better resistance to deformation, in particular due to a depression accompanying the cooling of the contents when it was introduced hot.
Un deuxième objectif est de proposer une solution permettant au récipient de conserver sa forme générale lorsqu'il est soumis à une dépression interne.  A second objective is to propose a solution allowing the container to retain its general shape when it is subjected to an internal depression.
Un troisième objectif est de proposer un récipient à section carrée qui n'ait pas tendance à adopter une forme en losange lorsqu'il est soumis à une dépression interne.  A third objective is to provide a square section container that does not tend to adopt a diamond shape when subjected to an internal depression.
Afin d'atteindre au moins l'un - et de préférence l'ensemble - de ces objectifs, il est proposé un récipient en matière plastique, comprenant un corps qui s'étend suivant un axe principal, une épaule qui s'étend dans le prolongement du corps d'un côté supérieur, et un fond qui s'étend dans le prolongement du corps d'un côté inférieur, le corps comprenant quatre faces, à savoir une première paire de faces qui, en section transversale, sont parallèles entre elles, et une deuxième paire de faces qui, en section transversale, sont parallèles entre elles et perpendiculaires aux faces de la première paire, les faces de la première paire étant écartées, en section transversale au voisinage de l'épaule comme au voisinage du fond, d'une distance D et les faces de la deuxième paire étant écartées, en section transversale au voisinage de l'épaule comme au voisinage du fond, d'une distance D', ce récipient étan tel que : In order to achieve at least one - and preferably all - of these objectives, there is provided a plastic container, comprising a body which extends along a main axis, a shoulder which extends in the extension of the body of an upper side, and a bottom which extends in the extension of the body of a lower side, the body comprising four faces, namely a first pair of faces which, in section transverse, are parallel to each other, and a second pair of faces which, in cross section, are parallel to each other and perpendicular to the faces of the first pair, the faces of the first pair being spaced, in cross section near the shoulder as in the vicinity of the bottom, a distance D and the faces of the second pair being spaced, in cross section near the shoulder as in the vicinity of the bottom, a distance D ', this container etan such that:
les valeurs de D et D' sont sensiblement égales, c'est-à-dire qu'elles vérifient la relation suivante :  the values of D and D 'are substantially equal, that is, they verify the following relation:
D'  OF
0,95 <— < 1,05  0.95 <- <1.05
en section transversale dans une zone médiane du corps, les faces de la première paire sont écartées d'une première distance D1 et les faces de la deuxième paire sont écartées d'une deuxième distance D2 différente de D1.  in cross section in a middle zone of the body, the faces of the first pair are separated by a first distance D1 and the faces of the second pair are separated by a second distance D2 different from D1.
Il résulte de cette forme une meilleure résistance du récipient aux déformations, notamment lors d'une dépression intérieure accompagnement le refroidissement du contenu.  It results from this form a better resistance of the container to the deformations, in particular during an internal depression accompanying the cooling of the contents.

D'autres objets et avantages de l'invention apparaîtront à la lumière de la description d'un mode de réalisation, faite ci-après en référence aux dessins annexés dans lesquels :  Other objects and advantages of the invention will become apparent in the light of the description of an embodiment, given hereinafter with reference to the accompanying drawings, in which:
la figure 1 est une vue de face réaliste montrant un récipient en matière plastique ;  Figure 1 is a realistic front view showing a plastic container;
- la figure 2 est une vue de côté du récipient de la figure 1, tournée de 90° par rapport à cette figure ; - Figure 2 is a side view of the container of Figure 1, rotated 90 ° with respect to this figure;
la figure 3 est une section transversale du récipient de la figure 1, prise indifféremment suivant le plan lll-lll ou le plan 111 '— 111 ' ;  Figure 3 is a cross section of the container of Figure 1, taken indifferently along the plane III-III or plane 111 '- 111';
la figure 4 est une section transversale du récipient de la figure 1, prise suivant le plan IV-IV.  Figure 4 is a cross section of the container of Figure 1, taken along the plane IV-IV.
Sur les figures 1 et 2 est représenté un récipient 1 (en l'occurrence une bouteille) en matière plastique telle que PET. Dans l'exemple illustré, le récipient est d'une capacité de 0,5 I, mais cette capacité pourrait être de n'importe quelle valeur appropriée ou connue, qu'elle soit inférieure (typiquement 0,33 I ou 0,25 I) ou supérieure (typiquement de 1,5 I, ou encore de 2 I).  In Figures 1 and 2 is shown a container 1 (in this case a bottle) of plastic such as PET. In the illustrated example, the container has a capacity of 0.5 I, but this capacity could be of any suitable or known value, be it lower (typically 0.33 I or 0.25 I). ) or higher (typically 1.5 I, or 2 I).
Le récipient 1 comprend plusieurs parties, à savoir un corps 2, une épaule 3 qui s'étend dans le prolongement du corps 2 à partir d'une extrémité supérieure de celui-ci, un col 4 qui surmonte l'épaule 3, et un fond 5 qui s'étend dans le prolongement du corps 2 à partir d'une extrémité inférieure de celui-ci.  The container 1 comprises several parts, namely a body 2, a shoulder 3 which extends in the extension of the body 2 from an upper end thereof, a neck 4 which overcomes the shoulder 3, and a bottom 5 which extends in the extension of the body 2 from a lower end thereof.
Le corps 2, qui forme la majeure partie du volume du récipient 1, s'étend suivant un axe X principal reliant approximativement le centre géométrique du col 4 et celui du fond 5. En supposant que le récipient 1 est destiné à être posé à plat sur un plan horizontal, l'axe X du récipient définit une direction verticale, tout plan orthogonal à l'axe X étant qualifiée de transversale et toute direction perpendiculaire à l'axe X étant qualifiée de radiale. The body 2, which forms the major part of the volume of the container 1, extends along a main axis X approximately connecting the geometric center of the neck 4 and that of the bottom 5. Assuming that the container 1 is intended to be laid flat on a horizontal plane, the X axis of the container defines a vertical direction, any plane orthogonal to the X axis being described as transverse and any direction perpendicular to the X-axis being qualified as radial.
L'épaule 3 complète le volume du récipient 1 et forme une jonction sensiblement conique entre le corps 2 et le col 4. Le fond 5 ferme transversalement le corps 2 vers le bas.  The shoulder 3 completes the volume of the container 1 and forms a substantially conical junction between the body 2 and the neck 4. The bottom 5 transversely closes the body 2 downwards.
Ce récipient 1, obtenu par soufflage, ou de préférence par étirage soufflage à partir d'une ébauche (c'est-à-dire une préforme ou un récipient intermédiaire ayant subi un premier soufflage non définitif) est particulièrement destiné à être rempli à chaud, la température du liquide de remplissage pouvant atteindre 95°C, soit une température qui peut être supérieure à la température de transition vitreuse du récipient 1, tout dépendant de son matériau (rappelons que la température de transition vitreuse du PET est d'environ 80°C).  This container 1, obtained by blowing, or preferably by stretching, from a blank (that is to say a preform or an intermediate container having undergone a first non-definitive blowing) is particularly intended to be hot filled. , the temperature of the filling liquid up to 95 ° C, a temperature that may be greater than the glass transition temperature of the container 1, depending on its material (remember that the glass transition temperature of the PET is about 80 ° C).
Selon un mode de réalisation préféré illustré sur les figures 1 et 2, le corps 2 est symétrique par rapport à un plan P médian situé sensiblement à mi-distance des extrémités du corps 2. Dans ce mode de réalisation, le corps 2 présente, au niveau du plan P médian, une ceinture 6 où le corps 2 est cintré, c'est-à-dire que ses dimensions transversales sont réduites.  According to a preferred embodiment illustrated in Figures 1 and 2, the body 2 is symmetrical with respect to a median plane P located substantially midway from the ends of the body 2. In this embodiment, the body 2 has, at the level of the median plane P, a belt 6 where the body 2 is bent, that is to say that its transverse dimensions are reduced.
La ceinture 6 divise le corps 2 en une section 7 supérieure, qui s'étend entre la ceinture 6 et l'épaule 3, et une section 8 inférieure, symétrique de la section 7 supérieure par rapport au plan P médian, et qui s'étend entre la ceinture 6 et le fond 5.  The belt 6 divides the body 2 into an upper section 7, which extends between the belt 6 and the shoulder 3, and a lower section 8, symmetrical with the section 7 greater than the median plane P, and which extends between the belt 6 and the bottom 5.
Le corps présente, dans sa section 7 supérieure comme dans sa section 8 inférieure, quatre faces qui s'étendent sensiblement verticalement de l'épaule 3 (respectivement du fond 5) à la ceinture 6, à savoir :  The body has, in its upper section 7 as in its lower section 8, four faces which extend substantially vertically from the shoulder 3 (respectively bottom 5) to the belt 6, namely:
une première paire de faces 9 latérales qui, en section transversale, sont parallèles entre elles,  a first pair of side faces 9 which, in cross section, are parallel to each other,
- une deuxième paire de faces 10 latérales qui, en section transversale, sont parallèles entre elles et perpendiculaires aux faces 9 de la première paire. - A second pair of side faces 10, in cross section, are parallel to each other and perpendicular to the faces 9 of the first pair.
Ainsi que représenté sur la figure 3, en section transversale au voisinage de l'épaule (plan de coupe lll-lll de la figure 1) comme au voisinage du fond (plan de coupe 111 '— 111 ' de la figure 1), les faces 9 de la première paire sont écartées d'une distance D, et les faces 10 de la deuxième paire sont écartées d'une distance D' égale ou sensiblement égale à la distance D entre les faces 9 de la première paire, l'expression « égale ou sensiblement égale » signifiant que l'écart entre les distances D et D' est strictement inférieur à 5%. As shown in FIG. 3, in cross section in the vicinity of the shoulder (section plane III-III of FIG. 1) as in the vicinity of the bottom (section plane 111 '- 111' of FIG. faces 9 of the first pair are separated by a distance D, and the faces 10 of the second pair are separated by a distance D 'equal to or substantially equal to the distance D between the faces 9 of the first pair, the expression "equal or substantially equal" meaning that the difference between the distances D and D 'is strictly less than 5%.
En d'autres termes :  In other words:
D' = D  D = D
avec :  with:
D'  OF
0,95 <— < 1,05  0.95 <- <1.05
Les faces 9 de la première paire ont de préférence la même largeur, notée L1. Les faces 10 de la deuxième paire ont également, de préférence, la même largeur, notée L2. Les largeurs L1 et L2 sont avantageusement égales ou sensiblement égales (au sens indiqué ci- dessus) :  The faces 9 of the first pair preferably have the same width, denoted L1. The faces 10 of the second pair also preferably have the same width, denoted L2. The widths L1 and L2 are advantageously equal to or substantially equal (in the sense indicated above):
Ll≥ L2  Ll≥ L2
avec : with:
En section transversale au voisinage de l'épaule 3 comme au voisinage du fond 5, les faces 9, 10 latérales sont ainsi inscrites dans un contour carré (ou quasiment carré) de côté D. Par abus de langage, on assimile à un carré un rectangle dont les côtés D, D' sont égaux ou sensiblement égaux au sens indiqué ci-dessus, en admettant par conséquent une variation de 5%.  In cross section in the vicinity of the shoulder 3 as in the vicinity of the bottom 5, the side faces 9, 10 are thus inscribed in a square (or almost square) outline of side D. By abuse of language, we consider a square a rectangle whose sides D, D 'are equal to or substantially equal to the direction indicated above, thus admitting a variation of 5%.
En revanche, en section transversale dans une zone médiane du corps 2 (en l'espèce au voisinage de la ceinture 6), les faces 9 de la première paire sont écartées d'une distance D1, tandis que les faces 10 de la deuxième paire sont écartées d'une distance D2 différente de D1, le terme « différent » signifiant que l'écart entre D1 et D2 est supérieur ou égal à 5%.  On the other hand, in cross-section in a median zone of the body 2 (in this case in the vicinity of the belt 6), the faces 9 of the first pair are separated by a distance D1, whereas the faces 10 of the second pair are separated by a distance D2 different from D1, the term "different" meaning that the difference between D1 and D2 is greater than or equal to 5%.
Comme le récipient 1 peut admettre une symétrie de rotation d'un quart de tour autour de son axe X principal, on peut arbitrairement décréter que D2 est strictement supérieure à D1 :  Since the container 1 can admit a rotational symmetry of a quarter turn around its main axis X, it can arbitrarily be decreed that D2 is strictly greater than D1:
D2 > Dl  D2> Dl
au sens où :  in the sense that:
Dl  Dl
—— < 0,95  - <0.95
Dl  Dl
Le rapport entre D1 et D2 ne dépasse toutefois pas 15%. Dans ce cas, les distances D1 et D2 sont dans un rapport tel que : Dl The ratio between D1 and D2, however, does not exceed 15%. In this case, the distances D1 and D2 are in a ratio such that: Dl
0,85 <— < 0,95  0.85 <- <0.95
Dans l'exemple illustré, ce rapport est de 0,93 environ :  In the example shown, this ratio is approximately 0.93:
Dl  Dl
——≥ 0,93  --≥ 0.93
D2  D2
En d'autres termes, en section transversale dans la zone médiane précitée, les faces 9, 10 sont inscrites dans un contour rectangle dont les côtés ont pour longueurs respectives D1 et D2, le terme « rectangle » signifiant, par opposition au carré défini ci-dessus, que le rapport entre ses côtés est supérieur ou égal à 5%.  In other words, in cross-section in the aforementioned median zone, the faces 9, 10 are inscribed in a rectangle contour whose sides have for respective lengths D1 and D2, the term "rectangle" meaning, as opposed to the square defined herein. above, that the ratio between its sides is greater than or equal to 5%.
En section transversale dans cette même zone médiane, les faces 9 de la première paire ont avantageusement la même longueur L1'. De même, les faces 10 de la deuxième paire ont avantageusement la même longueur L2'.  In cross-section in this same median zone, the faces 9 of the first pair advantageously have the same length L1 '. Similarly, the faces 10 of the second pair advantageously have the same length L2 '.
L'une au moins des distances D1 et D2 est de préférence inférieure à la distance D ; avantageusement, les distances D1 et D2 sont toutes deux inférieures à la distance D, de sorte que, comme illustré sur la figure 4, le rectangle dans lequel se trouve inscrit le corps 2 en section transversale au voisinage du col 4 comme au voisinage du fond 5 est strictement inclus dans le carré dans lequel se trouve inscrit le corps 2 en section transversale au voisinage du col 4 comme au voisinage du fond 5 (en pointillés sur la figure 3).  At least one of the distances D1 and D2 is preferably less than the distance D; advantageously, the distances D1 and D2 are both less than the distance D, so that, as illustrated in FIG. 4, the rectangle in which the body 2 is registered in cross-section in the vicinity of the neck 4 as well as in the vicinity of the bottom 5 is strictly included in the square in which is located the body 2 in cross section in the vicinity of the neck 4 as in the vicinity of the bottom 5 (dashed in Figure 3).
Comme on le voit bien sur les figures 1 et 2, les distances entre les faces 9, 10 parallèles deux à deux varient continûment le long de l'axe X du corps 2, respectivement de la valeur D (que l'on peut considérer maximale lorsque le plan de la section considéré est aussi proche que possible de l'extrémité supérieure ou, inversement, inférieure du corps 2) à la valeur D1, et de la valeur D à la valeur D2.  As can be seen in FIGS. 1 and 2, the distances between the faces 9, 10 parallel two by two vary continuously along the axis X of the body 2, respectively by the value D (which can be considered as maximum when the plane of the considered section is as close as possible to the upper end or, conversely, lower body 2) to the value D1, and the value D to the value D2.
En d'autres termes, la largeur du corps 2, mesurée transversalement, diminue progressivement - et non brusquement - depuis les extrémités du corps 2 jusqu'à sa zone médiane.  In other words, the width of the body 2, measured transversely decreases gradually - not abruptly - from the ends of the body 2 to its central zone.
Selon un mode de réalisation préféré, le corps 2 comprend en outre des facettes 11 en biseaux reliant les faces 9, 10.  According to a preferred embodiment, the body 2 further comprises facets 11 bevels connecting the faces 9, 10.
Comme on le voit sur la figure 3, en section transversale au voisinage de l'épaule (dans le plan lll-lll) comme au voisinage du fond (dans le plan 111 '— 111 ' ) , les facettes 11 forment de préférence avec les faces 9, 10 un angle A de 45° environ. En revanche, cet angle n'est pas constant le long de l'axe X du récipient 1. En effet, en section transversale dans ladite zone médiane du corps 2, les facettes 11 forment avec les faces 9 de la première paire un premier angle A1 strictement inférieur à 45°, tandis qu'inversement les facettes 11 forment avec les faces 10 de la deuxième paire un angle A2 strictement supérieur à 45°, complémentaire de l'angle A1 : As seen in FIG. 3, in cross section in the vicinity of the shoulder (in the plane III-III) as in the vicinity of the bottom (in the plane 111 '- 111'), the facets 11 form preferably with the faces 9, an angle A of about 45 °. On the other hand, this angle is not constant along the axis X of the container 1. Indeed, in cross-section in said median zone of the body 2, the facets 11 form with the faces 9 of the first pair a first angle A1 strictly less than 45 °, while conversely the facets 11 form with the faces 10 of the second pair an angle A2 strictly greater than 45 °, complementary to the angle A1:
A1 + A2 = 90°  A1 + A2 = 90 °
Selon un mode particulier de réalisation préféré, l'angle A1 est compris entre 37° environ (auquel cas l'angle A2 est de 53° environ) et 43° environ (auquel cas l'angle A2 est de 47° environ). De préférence, l'angle A1 est de 40° environ (l'angle A2 étant alors de 50° environ).  According to a particular preferred embodiment, the angle A1 is between about 37 ° (in which case the angle A2 is about 53 °) and about 43 ° (in which case the angle A2 is about 47 °). Preferably, the angle A1 is about 40 ° (the angle A2 is then about 50 °).
Comme on le voit bien sur les figures 3 et 4, les facettes 11 donnent au corps 2 une section transversale sensiblement octogonale. On peut cependant, par abus de langage, qualifier de carrée cette section, compte tenu de la largeur sensiblement plus faible des facettes 11 devant celle des faces 9, 10.  As can be seen in FIGS. 3 and 4, the facets 11 give the body 2 a substantially octagonal cross-section. However, by abuse of language, it can be described as square this section, given the significantly smaller width of the facets 11 before that of the faces 9, 10.
L'évolution d'une section sensiblement carrée (au voisinage des extrémités du corps 2) à une section sensiblement rectangulaire (dans une zone médiane du corps 2) évite une déformation en losange du corps 2 lorsque celui-ci est soumis à une dépression interne.  The evolution of a substantially square section (in the vicinity of the ends of the body 2) to a substantially rectangular section (in a central zone of the body 2) avoids a diamond deformation of the body 2 when it is subjected to an internal depression .
En effet, la section rectangulaire du corps 2 dans la zone médiane tend, sous l'effet d'une dépression dans le récipient 1, à s'aplatir encore par diminution de la distance D1 et augmentation conjointe de la distance D2, sans altération notable de la perpendicularité des faces 9 aux faces 10. On a illustré en trait mixte sur la figure 4 la section ainsi déformée du corps 2.  Indeed, the rectangular section of the body 2 in the median zone tends, under the effect of a depression in the container 1, to flatten further by decreasing the distance D1 and joint increase of the distance D2, without significant alteration. from the perpendicularity of the faces 9 to the faces 10. The dashed section of the body 2 has been shown in broken lines in FIG.
Cette déformation contrôlée est favorisée par les facettes 11, dont l'angle A1 tend à se refermer tandis qu'à contrario l'angle A2 tend à s'ouvrir, comme illustré par le trait mixte de la figure 4.  This controlled deformation is favored by the facets 11, whose angle A1 tends to close while in contrast the angle A2 tends to open, as illustrated by the broken line in Figure 4.
Cette déformation contrôlée permet de maintenir la rigidité du récipient 1, notamment lors de sa prise en main, et également d'en préserver l'esthétique, l'aplatissement du corps 2 dans la zone médiane demeurant imperceptible pour le consommateur.  This controlled deformation makes it possible to maintain the rigidity of the container 1, in particular during its handling, and also to preserve its aesthetics, the flattening of the body 2 in the central zone remaining imperceptible to the consumer.
Comme on le voit sur les figures 1 et 2, des panneaux 12 déformables peuvent être inclus dans les faces 9, 10, de sorte à absorber une partie des déformations dues aux variations de pression dans le récipient 1. As can be seen in FIGS. 1 and 2, deformable panels 12 can be included in the faces 9, 10, so that absorb some of the deformations due to pressure variations in the container 1.
En outre, des raidisseurs 13 peuvent également être prévus, notamment sur les facettes 11 pour limiter les déformations de celles-ci et ainsi favoriser la déformation contrôlée de la section rectangulaire du corps 2 dans la zone médiane, comme révélé ci-dessus.  In addition, stiffeners 13 may also be provided, especially on the facets 11 to limit the deformations thereof and thus promote the controlled deformation of the rectangular section of the body 2 in the central zone, as disclosed above.
