Description

L'invention a trait à la fabrication des récipients, notamment bouteilles ou pots, obtenus par soufflage ou étirage soufflage à partir de préformes en matière plastique, telle que du polyéthylène téréphtalate (PET).The invention relates to the manufacture of containers, especially bottles or jars, obtained by blow molding or stretch blow molding from plastic preforms, such as polyethylene terephthalate (PET).

La fabrication par soufflage d'un récipient consiste ordinairement à introduire dans un moule à l'empreinte du récipient une ébauche (une préforme ou un récipient intermédiaire obtenu par présoufflage d'une préforme) préalablement chauffée à une température supérieure à la température de transition vitreuse de la matière, et à injecter dans l'ébauche un fluide (notamment un gaz tel que de l'air) sous pression. Le soufflage peut être complété par un étirage préalable de l'ébauche au moyen d'une tige coulissante.The manufacture by blowing of a container usually consists in introducing into a mold to the imprint of the container a blank (a preform or an intermediate container obtained by pre-blowing a preform) previously heated to a temperature above the glass transition temperature of the material, and to inject into the blank a fluid (in particular a gas such as air) under pressure. The blowing can be completed by preliminary stretching of the blank by means of a sliding rod.

La double orientation moléculaire que subit la matière au cours du soufflage (axiale et radiale, respectivement parallèlement et perpendiculairement à l'axe général du récipient) confère au récipient une certaine rigidité structurelle.The double molecular orientation that the material undergoes during blowing (axial and radial, respectively parallel and perpendicular to the general axis of the container) gives the container a certain structural rigidity.

Mais la diminution - dictée par le marché - de la quantité de matière employée pour la fabrication des récipients amène les fabricants à recourir à des astuces de fabrication ou de forme pour rigidifier leurs récipients, la bi-orientation se révélant insuffisante. Il en résulte qu'à poids égal deux récipients n'ont pas nécessairement les mêmes performances mécaniques (tenue, rigidité).But the decrease - dictated by the market - of the amount of material used for the manufacture of containers leads manufacturers to use manufacturing tips or form to stiffen their containers, the bi-orientation being insufficient. As a result, with equal weight, two containers do not necessarily have the same mechanical performance (strength, rigidity).

Un procédé bien connu d'accroissement de la rigidité d'un récipient est la thermofixation, qui consiste à chauffer la paroi du moule pour augmenter par voie thermique le taux de cristallinité. Ce procédé, illustré par le brevet français FR 2 649 035 (Sidel ) et son équivalent américain US 5,145,632 , est employé notamment pour les applications HR (initiales du terme anglais "heat resistant", soit résistant à la chaleur), dans lesquelles le récipient est rempli à chaud.A well-known method of increasing the stiffness of a container is heat-setting, which involves heating the mold wall to thermally increase the crystallinity level. This process, illustrated by the French patent FR 2 649 035 (Sidel ) and its American counterpart US5,145,632 , is used in particular for HR applications (initials of the term "heat resistant" or heat resistant), in which the container is filled hot.

EP 2 133 277 A1 montre, comme art antérieur, un récipient équipé d'un fond renforcé qui comporte des rainures s'étendant radialement à partir d'une zone voûtée centrale jusqu'à une zone annulaire d'assise. Un pli sépare ladite zone centrale d'une autre partie voûtée dudit fond. Ce pli se termine aux bords desdites rainures, et ne s'étend donc pas dans leur fond. EP 2 133 277 A1 shows, as prior art, a container equipped with a reinforced bottom which has grooves extending radially from a central vaulted area to an annular seating area. A fold separates said central zone from another vaulted portion of said bottom. This fold ends at the edges of said grooves, and therefore does not extend in their bottom.

Mais, en raison de son coût et de la réduction de cadence qu'il impose, ce type de procédé ne saurait se généraliser aux applications ordinaires du type eau plate. Pour ces applications, la rigidité structurelle du fond dépend essentiellement de sa forme. Il est connu de rigidifier le fond au moyen de rainures radiales, cf. par ex. le brevet français FR 2 753 435 (Sidel ), qui décrit un récipient ayant les caractéristiques du préambule de la revendication 1. Le fond de ce récipient conserve sa tenue mécanique sans se retourner tant que les conditions de volume et/ou de pression dans le récipient sont normales. Cependant, lorsque ces conditions sont extrêmes, le fond a tendance à s'affaisser, allant jusqu'à se retourner. Ainsi, lorsque le récipient est stocké par forte chaleur, typiquement lorsqu'il est entreposé en palette en extérieur en plein soleil, la température du contenu peut atteindre ou dépasser 50°C, et l'augmentation de pression induite par la dilatation du contenu dépasser le seuil au-delà duquel le fond se retourne. Le récipient devient alors instable, avec un risque élevé d'affaissement de toute la palette. De même, lorsque le récipient est stocké en congélateur à des températures auxquelles le contenu gèle, la dilation induite par la solidification provoque un retournement du fond, le récipient devenant également instable.But, because of its cost and the reduction in cadence it imposes, this type of process can not be generalized to ordinary applications of the flat water type. For these applications, the structural rigidity of the bottom depends essentially on its shape. It is known to stiffen the bottom by means of radial grooves, cf. eg. the patent French FR 2 753 435 (Sidel ), which discloses a container having the features of the preamble of claim 1. The bottom of this container retains its mechanical strength without turning as long as the conditions of volume and / or pressure in the container are normal. However, when these conditions are extreme, the bottom tends to sag, even going back. Thus, when the container is stored in high heat, typically when stored in a pallet outdoors in full sun, the temperature of the contents may reach or exceed 50 ° C, and the pressure increase induced by the expansion of the contents exceed the threshold beyond which the bottom turns. The container then becomes unstable, with a high risk of collapse of the entire pallet. Similarly, when the container is stored in the freezer at temperatures at which the content freezes, the expansion induced by solidification causes a reversal of the bottom, the container also becoming unstable.

Il serait en théorie possible de former sur le fond de profondes réserves en creux (notamment une voûte profonde) susceptibles d'accroître la résistance mécanique du fond. Cependant, cette astuce de forme, aussi efficace soit-elle, nécessite à la fois un surcroît de matière, incompatible avec les exigences d'allègement précitées, et une pression de soufflage élevée, incompatible avec les exigences d'économie d'énergie, qui supposent au contraire une diminution de la pression de soufflage nécessaire au formage du récipient. A titre d'exemple, les cahiers des charges actuels pour le formage de bouteilles d'eau plate de capacité 0,5 litre imposent ordinairement une masse de l'ordre de 10 g, pour une pression de soufflage de l'ordre de 20 bar.It would be theoretically possible to form deep caverns on the bottom (in particular a deep vault) likely to increase the mechanical strength of the bottom. However, this trick of form, as effective as it is, requires both an additional material, incompatible with the aforementioned lightening requirements, and a high blowing pressure, incompatible with the energy saving requirements, which on the contrary, suppose a decrease in the blowing pressure necessary for forming the container. By way of example, the current specifications for forming flat water bottles with a capacity of 0.5 liters usually require a mass of the order of 10 g, for a blowing pressure of the order of 20 bar. .

Un premier objectif est d'améliorer les performances mécaniques des récipients à soufflabilité (c'est-à-dire capacité du récipient à être formé par soufflage) équivalente.A first objective is to improve the mechanical performance of the blowing containers (i.e. capacity of the container to be formed by blowing) equivalent.

Un deuxième objectif est de proposer un récipient dont la forme optimisée du fond lui confère un bon compromis entre soufflabilité, légèreté et rigidité.A second objective is to propose a container whose optimized bottom shape gives it a good compromise between breathability, lightness and rigidity.

Un troisième objectif est de proposer un récipient dont le fond offre une bonne résistance au retournement, et qui, dans des conditions extrêmes de pression et/ou de volume interne, puisse demeurer stable.A third objective is to provide a container whose bottom offers good resistance to overturning, and which, under extreme conditions of pressure and / or internal volume, can remain stable.

A cet effet, il est proposé un récipient en matière plastique, muni d'un corps et d'un fond s'étendant à partir d'une extrémité inférieure du corps, le fond comprenant une assise périphérique définissant un plan de pose, une voûte concave qui s'étend à partir d'une zone centrale jusqu'à l'assise et une série de rainures de renfort qui s'étendent radialement à partir de la zone centrale jusqu'à l'assise au moins, récipient dans lequel la voûte présente deux régions concentriques, à savoir une région centrale et une région périphérique, séparées par un décrochement axial médian qui s'étend annulairement de manière continue autour de la zone centrale, en sorte que la région centrale se trouve surélevée par rapport à la région périphérique.For this purpose, it is proposed a plastic container, provided with a body and a bottom extending from a lower end of the body, the bottom comprising a peripheral base defining a laying plane, a concave arch which extends from a central zone to the seat and a series of reinforcing grooves which extend radially from the central zone to at least the seat, a vessel in which the vault has two concentric regions, namely a central region and a peripheral region, separated by a median axial recess which extends annularly continuously around the central zone so that the central region is elevated in relation to the peripheral region.

Grâce à ce décrochement, le fond garantit la stabilité du récipient même dans des conditions de pression et/ou de volume extrêmes.Thanks to this recess, the bottom guarantees the stability of the container even under extreme pressure and / or volume conditions.

  • the figure 4 is a central sectional view, in perspective, of the container of the figure 3 ;
  • the figure 5 is a central sectional view of the container of the figure 3 .

Sur la figure 1 est représenté un récipient 1, en l'occurrence une bouteille, réalisé par étirage soufflage à partir d'une préforme en matière thermoplastique, par exemple en PET (polyéthylène téréphtalate).On the figure 1 there is shown a container 1, in this case a bottle, made by stretch blow molding from a thermoplastic preform, for example PET (polyethylene terephthalate).

Ce récipient 1 comprend, à une extrémité supérieure, un col 2, muni d'un buvant 3. Dans le prolongement du col 2, le récipient 1 comprend dans sa partie supérieure une épaule 4 allant en s'évasant dans la direction opposée au col 2, cette épaule 4 étant prolongée par une paroi latérale ou corps 5, de forme généralement cylindrique de révolution autour d'un axe X principal du récipient 1. This container 1 comprises, at an upper end, a neck 2, provided with a rim 3. In the extension of the neck 2, the container 1 comprises in its upper part a shoulder 4 flaring in the opposite direction to the neck 2, this shoulder 4 being extended by a side wall or body 5, of generally cylindrical shape of revolution about a main axis X of the container 1.

Le récipient 1 comprend en outre un fond 6 qui s'étend à l'opposé du col 2, à partir d'une extrémité inférieure du corps 5. Le fond 6 comprend une assise 7 périphérique sous forme d'un bourrelet annulaire qui s'étend sensiblement axialement dans le prolongement du corps 5. L'assise 7 se termine par un plan 8 de pose perpendiculaire à l'axe X du récipient 1, lequel plan 8 de pose définit l'extrémité inférieure du récipient 1 et lui permet d'être posé, debout, sur une surface plane.The container 1 further comprises a bottom 6 which extends opposite the neck 2, from a lower end of the body 5. The bottom 6 comprises a peripheral seat 7 in the form of an annular bead which extends substantially axially in the extension of the body 5. The seat 7 terminates in a laying plane 8 perpendicular to the axis X of the container 1, which laying plane 8 defines the lower end of the container 1 and allows it to stand on a flat surface

On note D1 le diamètre du plan 8 de pose, le terme « diamètre » couvrant non seulement le cas (illustré) où le récipient 1 (et donc le fond 6) est à contour circulaire, mais également le cas où le récipient 1 serait à contour polygonal (par exemple carré), auquel cas le terme « diamètre » désignerait le diamètre du cercle dans lequel s'inscrirait ce polygone.Note D1 the diameter of the laying plane 8 , the term "diameter" not only covering the case (illustrated) where the container 1 (and thus the bottom 6) is circular contour, but also the case where the container 1 would be at polygonal contour (for example square), in which case the term "diameter" would designate the diameter of the circle in which this polygon would be inscribed.

Vers l'intérieur du récipient 1, l'assise 7 comprend une joue 9 annulaire tronconique qui s'étend vers l'intérieur du récipient 1 dans le prolongement du plan 8 de pose, le tronc de cône formé par la joue 9 s'ouvrant vers le bas (en dépouille) et présentant un angle au sommet d'au moins 70°. Cette joue 9 peut présenter une hauteur comprise entre 1 mm et 3 mm, par exemple d'environ 1,5 mm.Towards the interior of the container 1, the seat 7 comprises a frustoconical annular cheek 9 which extends towards the interior of the container 1 in the extension of the laying plane 8 , the truncated cone formed by the cheek 9 opening downward (in relief) and having an apex angle of at least 70 °. This cheek 9 may have a height of between 1 mm and 3 mm, for example about 1.5 mm.

Le fond 6 comprend en outre une voûte 10 concave, sous forme d'une calotte sensiblement sphérique à concavité tournée vers l'extérieur du récipient 1 en l'absence de contrainte, c'est-à-dire en l'absence de contenu dans le récipient 1. La voûte 10 s'étend à partir de l'assise 7, dans le prolongement de la joue 9, jusqu'à une zone 11 centrale du fond 6 formant un pion en saillie vers l'intérieur du récipient 1, avec en son centre une pastille 12 amorphe qui correspond à la zone d'injection du matériau constitutif de la préforme ayant servi à réaliser le récipient et peut remplir une fonction de centrage lors du formage, par soufflage, du récipient 1. The bottom 6 further comprises a concave arch 10 , in the form of a substantially spherical cap with concavity turned towards the outside of the container 1 in the absence of stress, that is to say in the absence of content in the container 1. The arch 10 extends from the seat 7, in the extension of the cheek 9, to a central zone 11 of the bottom 6 forming a pin projecting towards the inside the container 1, with at its center an amorphous pellet 12 which corresponds to the injection zone of the constituent material of the preform used to make the container and can fulfill a centering function during the blow molding of the container 1 .

Comme cela est visible sur les figures, et en particulier sur la figure 2, le fond 6 comprend une série de rainures 13 principales de renfort formées en creux vers l'intérieur du récipient 1, qui s'étendent radialement à partir de la zone 11 centrale, jusqu'à l'assise 7 au moins. Selon un mode préféré de réalisation, illustré sur les figures, les rainures 13 principales de renfort se prolongent radialement au-delà de l'assise 7, remontant latéralement sur une partie inférieure du corps 5. As can be seen in the figures, and in particular on the figure 2 , the bottom 6 comprises a series of main reinforcing grooves 13 formed recessed towards the inside of the container 1, which extend radially from the central zone 11 , to the seat 7 at least. According to a preferred embodiment, illustrated in the figures, the main reinforcing grooves 13 extend radially beyond the seat 7, rising laterally on a lower part of the body 5.

En d'autres termes, les rainures 13 principales s'étendent radialement sur la totalité de la voûte 10, à cheval sur l'assise 7 et partiellement sur le corps 5. On comprend par conséquent que le plan 8 de pose est discontinu, puisqu'interrompu au droit de chaque rainure 13 principale. Les rainures 13 principales sont par exemple au nombre de cinq (comme dans l'exemple illustré, qui correspond à un récipient d'une capacité de 0,5 litre), mais ce nombre pourrait être supérieur, notamment de six dans le cas d'un récipient d'une capacité supérieure ou égale à 1 litre, ou encore de sept dans le cas d'un récipient d'une capacité supérieure ou égale à 2,5 litre.In other words, the main grooves 13 extend radially over the entire roof 10, straddling the seat 7 and partially on the body 5. It is therefore understood that the laying plane 8 is discontinuous, since interrupted at the right of each main groove 13 . The main grooves 13 are for example five in number (as in the example illustrated, which corresponds to a container with a capacity of 0.5 liter), but this number could be higher, especially six in the case of a container with a capacity greater than or equal to 1 liter, or seven in the case of a container with a capacity greater than or equal to 2.5 liters.

Selon un mode préféré de réalisation, le fond 6 est en outre pourvu d'une série de rainures 14 intercalaires de renfort, situées entre les rainures 13 principales, et qui s'étendent localement à cheval sur l'assise 7 qu'elles contribuent ainsi à rigidifier. Ainsi que représenté sur les figures 2 et 3, les nervures 14 intercalaires se prolongent vers l'extérieur au-delà de l'assise 7 en remontant latéralement sur une partie inférieure du corps 5, comme les rainures 13 principales. On voit également sur les figures 2 et 3 que les nervures 14 intercalaires chevauchent la joue 9 mais sont interrompues à la périphérie de la voûte 10. According to a preferred embodiment, the bottom 6 is further provided with a series of interleaving reinforcement grooves 14 , located between the main grooves 13 , and which extend locally astride the seat 7, which they thus contribute. to stiffen. As shown on the figures 2 and 3 , the intermediate ribs 14 extend outwardly beyond the seat 7 upwards laterally on a lower part of the body 5, as the main grooves 13 . We also see on figures 2 and 3 that the intermediate ribs 14 overlap the cheek 9 but are interrupted at the periphery of the vault 10.

Comme on le voit sur les figures, et plus nettement sur les figures 2, 4 et 5, la voûte 10 présente deux régions concentriques, à savoir une région 15 centrale annulaire entourant la zone 11 centrale du fond 6, et une région 16 périphérique annulaire entourant la région 15 centrale, séparées par un décrochement 17 qui s'étend axialement sur une hauteur H prédéterminée. Ce décrochement 17 est médian par rapport à la voûte 10, c'est-à-dire que la région 15 centrale et la région 16 périphérique présentent sensiblement la même extension radiale.As we see in the figures, and more clearly on the figures 2 , 4 and 5 , The vault 10 has two concentric parts, namely a central area 15 surrounding the central annular zone 11 of the bottom 6, and an annular peripheral region 16 surrounding the central region 15, separated by a shoulder 17 which extends axially over a predetermined height H. This offset 17 is median with respect to the arch 10, that is to say that the central region 15 and peripheral region 16 have substantially the same radial extension.

Selon l'invention, ce décrochement 17 s'étend de manière continue, c'est-à-dire qu'il n'est pas interrompu au droit des rainures 13 principales mais s'étend jusqu'au fond de celles-ci.According to the invention, this recess 17 extends continuously, that is to say, it is not interrupted to the right of the main grooves 13 but extends to the bottom thereof.

Le décrochement 17 axial s'étend annulairement autour de la zone 11 centrale. Dans le mode de réalisation représenté, où le récipient 1 est de forme sensiblement cylindrique de révolution autour de son axe X, le décrochement 17 forme un anneau à contour circulaire dont on note D2 le diamètre. Dans des variantes déjà évoquées, où le récipient 1 présenterait en section transversale un contour polygonal, le décrochement 17 présenterait également un contour polygonal, homothétique au contour extérieur du récipient 1. D2 désignerait alors le diamètre du cercle dans lequel s'inscrirait le contour polygonal du décrochement.The axial recess 17 extends annularly around the central zone 11 . In the embodiment shown, where the container 1 has a substantially cylindrical shape of revolution about its axis X, the recess 17 forms a ring with a circular contour whose diameter D2 is noted. In variants already mentioned, where the container 1 has a polygonal contour in cross section, the recess 17 also has a polygonal contour, homothetic to the outer contour of the container 1. D2 then denotes the diameter of the circle in which the polygonal contour would be inscribed. of the detachment.

Par la présence du décrochement 17 axial, la région 15 centrale, bien qu'ayant un rayon de courbure sensiblement identique à celui de la région 16 périphérique, se trouve légèrement surélevée par rapport celle-ci, en étant décalée vers l'intérieur du récipient 1. By the presence of the axial offset 17, the central region 15, although having a radius of curvature substantially identical to that of the peripheral region 16, is slightly raised relative thereto, being offset towards the interior of the container 1.

Selon un mode de réalisation, le diamètre D2 du décrochement 17 est compris entre 40% et 60% du diamètre D1 du plan 8 de pose. Dans l'exemple illustré, le rapport D2/D1 est d'environ 50%.According to one embodiment, the diameter D2 of the recess 17 is between 40% and 60% of the diameter D1 of the laying plane 8 . In the illustrated example, the ratio D2 / D1 is about 50%.

Quant à la hauteur H du décrochement 17, elle est sensiblement constante sur son contour, en étant avantageusement comprise entre 0,4 mm et 1,2 mm. Pour un récipient d'une capacité de 0,5 litre (ce qui correspond à l'exemple illustré), cette hauteur H est plutôt comprise entre 0,4 mm et 0,7 mm, et par exemple d'environ 0,5 mm. Pour un récipient d'une capacité de 1,5 litre ; la hauteur H du décrochement 17 est plutôt comprise entre 0,7 et 1,2 mm, et par exemple d'environ 1 mm.As for the height H of the recess 17, it is substantially constant on its contour, being advantageously between 0.4 mm and 1.2 mm. For a container with a capacity of 0.5 liter (which corresponds to the example shown), this height H is rather between 0.4 mm and 0.7 mm, and for example about 0.5 mm . For a container with a capacity of 1.5 liters; the height H of the recess 17 is rather between 0.7 and 1.2 mm, and for example about 1 mm.

Le décrochement 17 a pour fonction de maintenir la stabilité du récipient 1 dans des conditions de pression et/ou de volume extrêmes, notamment lorsqu'il règne dans le récipient 1 une surpression induite par une dilatation du contenu et du volume sous col, due par exemple à une exposition du récipient 1 (plein) au soleil, ou lorsque le contenu subit une dilatation induite par sa solidification, due par exemple au stockage du récipient 1 (plein) en congélateur.The recess 17 serves to maintain the stability of the container 1 under extreme pressure and / or volume conditions, particularly when there is a pressure in the container 1 caused by expansion of the contents and the volume under the neck, caused by example to an exposure of container 1 (full) to the sun, or when the contents undergoes a dilation induced by its solidification, due for example to the storage of the container 1 (full) in the freezer.

Dans ces conditions, le contenu exerce sur le fond 6 une pression qui tend à l'affaisser. Le décrochement 17 s'oppose toutefois au retournement complet du fond 6 en induisant une rigidification de la voûte 10 dans sa région médiane, et en limitant la déformation de la voûte 10 de sorte à élargir l'assise 7 (comme suggéré par les pointillés sur la figure 5) vers le centre du fond 6. Au maximum, le fond 6 subit effectivement un retournement mais de manière contrôlée, la région 15 centrale de la voûte 10 formant alors une assise secondaire par laquelle le récipient 1 peut reposer de manière stable sur une surface support.Under these conditions, the content exerts on the bottom 6 a pressure that tends to collapse. The recess 17 opposes, however, the complete reversal of the bottom 6 by inducing a stiffening of the vault 10 in its central region, and limiting the deformation of the vault 10 so as to widen the seat 7 (as suggested by the dotted lines on the figure 5 ) Toward the bottom center 6. At maximum, the bottom 6 but actually undergoes a reversal in a controlled manner, the central region 15 of the arch 10, so forming a secondary seat by which the container 1 can rest stably on a support surface .

Si le diamètre D2 du décrochement 17 était trop faible (typiquement inférieur à 40% du diamètre D1 du plan 8 de pose), la surface de l'assise secondaire formée par la région 15 centrale retournée serait trop faible et le récipient serait instable. Si au contraire le diamètre D2 du décrochement 17 était trop important (typiquement supérieur à 60% du diamètre D1 du plan de 8 pose), le risque de retournement du fond 6 serait accru, la déformation de la voûte 10 moins bien contrôlée, et il en résulterait une instabilité du récipient.If the diameter D2 of the recess 17 is too small (typically less than 40% of the diameter D1 of the plane 8 setting), the surface of the secondary seat formed by the central region 15 returned would be too low and the container would be unstable. If instead the diameter D2 of the recess 17 was too large (typically greater than 60% of the diameter D1 of the plane 8 setting), the risk of rollover of the bottom 6 is increased, the deformation of the 10 less well controlled arch, and resulting in instability of the container.

Un décrochement 17 axial (c'est-à-dire cylindrique) s'étendant sur une hauteur H relativement faible offre un bon compromis entre le contrôle de la déformation du fond 6 telle qu'elle vient d'être décrite, et une bonne soufflabilité du fond 6. An axial (ie cylindrical) recess 17 extending over a relatively low height H offers a good compromise between the control of the deformation of the bottom 6 as just described, and a good blowing ability. from the bottom 6.

Ainsi, un récipient 1 en PET correspondant à la forme illustrée, d'une capacité de 0,5 litre, d'une masse de 10 g, a pu être soufflé sans difficulté à une pression d'air de 19 bars, le récipient 1 final rempli d'eau plate offrant de bonnes performances mécaniques dans les conditions extrêmes précitées (exposition au soleil à 50°C et congélation à -18°C) : la déformation du fond 6 demeure contrôlée, la région 15 centrale de la voûte 10 formant une assise secondaire permettant au récipient 1 reposant sur une surface horizontale de conserver une bonne stabilité.Thus, a container 1 of PET corresponding to the illustrated form, with a capacity of 0.5 liter, a mass of 10 g, could be easily blown at an air pressure of 19 bar, the container 1 final filled with plain water with good mechanical performance in the above extreme conditions (sun exposure at 50 ° C and freezing at -18 ° C): the deformation of the base 6 remains controlled, the central region 15 of the arch 10 forming a secondary seat allowing the container 1 resting on a horizontal surface to maintain good stability.

Une augmentation de la hauteur H du décrochement 17 pourrait accroître la rigidité du fond 6, mais induirait parallèlement une diminution de sa soufflabilité au niveau du décrochement 17, sauf à donner à celui-ci de la dépouille, ce qui diminuerait alors la rigidité du fond 6. An increase in the height H of the recess 17 could increase the stiffness of the bottom 6, but at the same time induce a decrease in its blowing at the recess 17, except at give it one's body, which would then reduce the rigidity of the bottom 6.

Le récipient 1 muni de ce fond 6 présente un bon compromis entre les performances mécaniques (c'est-à-dire la capacité du récipient 1 à résister aux déformations et, lorsque celles-ci surviennent, à les subir de manière contrôlée) et la soufflabilité (c'est-à-dire la capacité du récipient 1 à être formé par soufflage).The container 1 provided with this bottom 6 has a good compromise between the mechanical performance (that is to say the capacity of the container 1 to resist deformations and, when they occur, to undergo them in a controlled manner) and the blowing (that is to say the capacity of the container 1 to be formed by blowing).
