Abstract

A saturated polyester resin high pressure bottle has a spherical bottom and is provided with a standing leg (7). The bottle body (1) has a reduced dia. part (5a) at its lower part. Standing leg (7) is formed with peripheral walls (8,9) and bottle holder (10).

Description

La présente invention se rapporte à une bouteille de grandes dimensions en résine polyester saturée, destinée à être remplie, sous forte pression, d'un liquide tel qu'une boisson carbonatée et elle vise plus spécialement une bouteille d'un tel type, capable de se tenir debout, même si son fond est de forme sphérique.The present invention relates to a large bottle of saturated polyester resin, intended to be filled, under high pressure, with a liquid such as a carbonated drink and more specifically relates to a bottle of such a type, capable of stand upright, even if its bottom is spherical.

Il est courant d'utiliser des bouteilles en verre de grandes dimensions, que l'on remplit sous une pression élevée et dont le contenu est destiné à être utilisé par petites quantités. Toutefois, en raison des grandes dimensions de la bouteille, le poids du liquide dont elle est remplie est très grand et, de- plus, la bouteille doit avoir une très grande épaisseur pour résister à la pression élevée à laquelle est soumis son contenu. Il en résulte que le poids total de la bouteille remplie est très grand, ce qui rend peu commode le maniement de la bouteille et augmente le prix de son transport.It is common to use large glass bottles, which are filled under high pressure and whose contents are intended to be used in small quantities. However, due to the large dimensions of the bottle, the weight of the liquid with which it is filled is very large and, moreover, the bottle must have a very large thickness in order to withstand the high pressure to which its contents are subjected. As a result, the total weight of the filled bottle is very large, which makes handling of the bottle inconvenient and increases the cost of transporting it.

Dans le prix des boisssons carbonatées indiquées plus haut, le quotient du prix du stockage et du transport par rapport aux autres frais est beaucoup plus élevé que pour d'autres dentrées. La bouteille de grandes dimensions mentionnée ci-dessus vise à diminuer le prix du stockage, mais sa possibilité de transport est limitée. En vue de remédier à un tel inconvénient, il a déjà été imaginé une bouteille de grandes dimensions, en résine synthétique, étirée suivant deux axes, comportant un col incliné, une partie principale cylindrique et un fond en forme de calotte sphérique convexe vers le bas. Si l'on moule une bouteille en lui donnant une telle forme, l'expérience confirme que cette bouteille est en mesure de supporter une forte pression intérieure, même si elle est mince et légère. Mais, du fait que si son fond a une telle forme sphérique convexe vers le bas, une telle bouteille ne peut pas se tenir debout elle-même, il est indispensable de lui fixer un support. Or, aucun support pour bouteille ne s'est révélé satisfaisant du point de vue de son prix de revient, d'un maniement facile la bouteille et de sa résistance sous l'effet du poids vé de la bouteille remplie de liquide.In the price of carbonated beverages indicated above, the quotient of the price of storage and transport compared to other costs is much higher than for other inputs. The large bottle mentioned above aims to reduce the price of storage, but its possibility of transport is limited. In order to remedy such a drawback, a bottle of large dimensions, made of synthetic resin, stretched along two axes, has already been imagined, comprising an inclined neck, a cylindrical main part and a bottom in the shape of a convex spherical cap downwards. . If we mold a bottle by giving it such a shape, experience confirms that this bottle is able to withstand strong internal pressure, even if it is thin and light. But, since its bottom has such a downward convex spherical shape, such a bottle cannot stand upright itself, it is essential to fix a support for it. However, no bottle holder has proved satisfactory from the point of view of its cost price, of an easy handling. the bottle and its resistance under the effect of the weight of the bottle filled with liquid.

L'objet de l'invention est de maintenir fermement n position droite une bouteille dont le fond est de forme sphérique pour pouvoir supporter une charge soumise à une pression élevée, en fixant un support à cette bouteille. La paroi périphérique verticale de ce support et la partie qui retient le fond de la bouteille sont d'un seul tenant ; la surface de l'extrémité inférieure de cette paroi péri- ohérique verticale est élargie de manière à assurer le main- ien de la bouteille, ou bien cette paroi comporte des ervures destinées à augmenter sa résistance.The object of the invention is to firmly maintain an upright position in a bottle whose bottom is spherical in order to be able to support a load subjected to high pressure, by fixing a support to this bottle. The vertical peripheral wall of this support and the part which retains the bottom of the bottle are in one piece; the surface of the lower end of this vertical periherical wall is widened so as to maintain the bottle, or else this wall has grooves intended to increase its resistance.

On donne à la bouteille en résine polyester saturée selon l'invention de grandes dimensions en étirant suivant deux axes une paraison moulée par injection. Le corps 1 de la bouteille est muni d'un goulot 2 comportant des filets 3 servant à fixer un bouchon. Plus bas que ce goulot, se trouve un col incliné 4, au-dessous duquel se trouve une partie cylindrique 5. L'extrémité inférieure de cette partie cylindrique 5 est fermée par une paroi de fond 6 ayant la forme d'une calotte sphérique convexe vers le bas. La partie inférieure de cette partie cylindrique 5 constitue une partie 5a de plus petit diamètre, et le gradin 5b situé à l'extrémité extérieure de cette partie 5a permet de retenir l'extrémité supérieure d'un support de bouteille, que l'on décrira ci-après.The bottle in saturated polyester resin according to the invention is given large dimensions by stretching along two axes an injection molded parison. The body 1 of the bottle is provided with a neck 2 comprising threads 3 used to fix a stopper. Lower than this neck is an inclined neck 4, below which is a cylindrical part 5. The lower end of this cylindrical part 5 is closed by a bottom wall 6 having the shape of a convex spherical cap. down. The lower part of this cylindrical part 5 constitutes a part 5a of smaller diameter, and the step 5b located at the outer end of this part 5a makes it possible to retain the upper end of a bottle support, which will be described below.

Ce support de bouteille 7 est façonné suivant un cylindre muni d'un fond, dont la paroi périphérique supérieure 8 s'adapte fermement sur la partie de plus petit diamètre 5a, de telle manière que l'extrémité supérieure de cette paroi périphérique 8 soit retenue dans la partie en gradins 5b de la bouteille. La partie inférieure 9 de la paroi périphérique du support 7 est repliée de telle manière que sa ligne de pliage soit contenue dans un plan. La partie 10 du support 7 destinée à recevoir le fond de la bouteille est de formesphérique et convexe vers le bas pour recevoir la paroi de fond 6 de la bouteille, cette partie 10 du support étant telle que son centre se trouve dans le plan de l'extrémité inférieure de la paroi périphérique inférieure 9.This bottle support 7 is shaped according to a cylinder provided with a bottom, the upper peripheral wall 8 of which fits firmly on the part of smaller diameter 5a, so that the upper end of this wall device 8 is retained in the stepped portion 5b of the bottle. The lower part 9 of the peripheral wall of the support 7 is folded so that its fold line is contained in a plane. The part 10 of the support 7 intended to receive the bottom of the bottle is spherical and convex downwards to receive the bottom wall 6 of the bottle, this part 10 of the support being such that its center is in the plane of the the lower end of the lower peripheral wall 9.

Comme on le voit plus nettement sur la fig. 2, le support 7 est un cylindre muni d'un fond, con titué par une partie 10' de forme sphérique, destinée à recevoir le fond d'une bouteille, par une paroi périphérique supérieure 8' d'un diamètre plus grand et par une paroi périphérique inférieure 9' d'un diamètre plus petit. Ce support 7 ainsi constitué prend la forme d'une pièce moulée mince d'un seul tenant, par moulage sous vide d'une feuille en une résine synthétique appropriée. De façon plus précise, on plie la pièce moulée ainsi obtenue vers l'intérieur, suivant le bord supérieur de la petite paroi périphérique inférieure 9', puis on replie cette pièce moulée en direction de l'extérieur, suivant le pourtour de la partie 10' destinée à recevoir le fond d'une bouteille.As can be seen more clearly in FIG. 2, the support 7 is a cylinder provided with a bottom, constituted by a part 10 'of spherical shape, intended to receive the bottom of a bottle, by an upper peripheral wall 8' of a larger diameter and by a lower peripheral wall 9 'of a smaller diameter. This support 7 thus formed takes the form of a thin molded piece in one piece, by vacuum molding of a sheet of a suitable synthetic resin. More precisely, the molded part thus folded is folded inwards, along the upper edge of the small lower peripheral wall 9 ′, then this molded part is folded towards the outside, along the periphery of the part 10 'intended to receive the bottom of a bottle.

La bouteille en résine polyester saturée ainsi réalisée peut avoir d'excellentes propriétés mécaniques même si elle est mince, du fait qu'elle est obtenue par moulage suivant le procédé d'étirage suivant deux axes.The bottle made of saturated polyester resin thus produced can have excellent mechanical properties even if it is thin, because it is obtained by molding according to the drawing process along two axes.

Une telle bouteille peut également supporter de fortes pressions étant donné qu'elle comporte un col incliné 4, une partie cylindrique 5 et une paroi inférieure 6 en forme de calotte sphérique convexe vers le bas. En outre, étant donné qu'en dépit de sa paroi inférieure 6, en forme de calotte sphérique,vers le bas, la bouteille est retenue par le support 7, elle peut demeurer en position bien droite , ce qui permet de stocker de façon satisfaisante une telle bouteilles remplies d'un liquide. De plus, du fait que la partie périphérique inférieure du support 7 est une paroi double, un tel support peut être suffisamment résistant pour supporter la charge d'une bouteille remplie d'un liquide.Such a bottle can also withstand high pressures since it has an inclined neck 4, a cylindrical part 5 and a bottom wall 6 in the form of a convex downwardly domed cap. In addition, given that despite its bottom wall 6, in the form of a spherical cap, downwards, the bottle is retained by the support 7, it can remain in a very upright position, which makes it possible to store satisfactorily such a bottles filled with liquid. In addition, since the lower peripheral part of the support 7 is a double wall, such a support can be strong enough to support the load of a bottle filled with a liquid.

En outre, étant donné que le support 7 est obtenu par moulage, sous la forme d'une pièce mince d'un seul tenant, d'une résine polyester saturée, la quantité de matériau moulé est si faible et la construction du support est si simple que son prix de revient est faible. Enfin, ce qui représente un grand avantage, du fait que l'ensemble de la bouteille peut être léger au point de rendre négligeable le prix du transport, une telle -bouteille convient remarquablement pour des liquides soumis à une forte pression mais de faible valeur, comme par exemple les boissons carbonatées.Furthermore, since the support 7 is obtained by molding, in the form of a thin piece in one piece, of a saturated polyester resin, the amount of molded material is so small and the construction of the support is so simple that its cost price is low. Finally, which represents a great advantage, owing to the fact that the whole of the bottle can be light to the point of making the transport price negligible, such a bottle is remarkably suitable for liquids subjected to high pressure but of low value, like carbonated drinks for example.

Dans le cas de la forme de réalisation précédente, si, pour donner au support 7 une assise plus grande, on introduit un matériau de remplissage 11 dans l'intervalle compris entre la partie inférieure 9a et la partie extérieure 9b de la paroi périphérique inférieure 9 de ce support (fig. 3), on peut améliorer la stabilité de la bouteiLle.In the case of the previous embodiment, if, to give the support 7 a larger seat, a filling material 11 is introduced in the interval between the lower part 9a and the external part 9b of the lower peripheral wall 9 of this support (fig. 3), the stability of the bottle can be improved.

Selon une variante, on peut prévoir une saillie 12 de forme annulaire (fig. 4) sur le côté intérieure du bord supérieur de la paroi périphérique B du support 7, ou bien une saillie 13, également de forme annulaire mais creuse, au même endroit de la paroi 8 (fig. 5), et prévoir également, à l'extrémité supérieure de la partie cylindrique de petit diamètre 5a de la bouteille, une rainure annulaire 14, correspondant soit à la saillie 12, soit à la saillie 13. Avec une telle forme de réalisation, étant donné que la saillie annulaire 12 ou la saillie annulaire, mais creuse, 13, s'enfonce d'un coup sec dans la rainure annulaire correspondante 14, le support 7 se trouve fixé plus fermement à la bouteille et la partie cylindrique de cette bouteille se trouve renforcée.According to a variant, it is possible to provide a projection 12 of annular shape (FIG. 4) on the inner side of the upper edge of the peripheral wall B of the support 7, or else a projection 13, also of annular shape but hollow, in the same place. of the wall 8 (fig. 5), and also provide, at the upper end of the small-diameter cylindrical part 5a of the bottle, an annular groove 14, corresponding either to the projection 12, or to the projection 13. With such an embodiment, given that the annular projection 12 or the annular, but hollow projection, 13, snaps into the corresponding annular groove 14, the support 7 is more firmly attached to the bottle and the cylindrical part of this bottle is reinforced.

On décrira ci-après, en se reportant à la fig. 6, une forme de réalisation selon laquelle la surface de contact avec le sol est plus grande. Dans ce nouvel exemple, la partie retournée vers le haut 9a' de la paroi périphérique inférieure 9 du support 7 délimite, avec la partie extérieure 9b de la paroi périphérique 9, un espace A qui donne une plus grande largeur à l'assise 9c de cette paroi périphérique inférieure 9. En outre, l'extrémité supérieure de la partie redressée 9a' touche la partie extétieure 9b de la paroi périphérique inférieure, tandis que la partie 10' en forme de calotte sphérique, destinée à recevoir le fond d'une bouteille et qui se raccorde sur cette partie retournée 9a', a son centre situé plus haut que l'extrémité inférieure de la paroi périphérique 9.We will describe below, referring to FIG. 6, an embodiment according to which the contact surface with the soil is larger. In this new example, the part turned upwards 9a ′ of the lower peripheral wall 9 of the support 7 defines, with the external part 9b of the peripheral wall 9, a space A which gives greater width to the seat 9c of this lower peripheral wall 9. In addition, the upper end of the straightened part 9a 'touches the outer part 9b of the lower peripheral wall, while the part 10' in the form of a spherical cap, intended to receive the bottom of a bottle and which is connected to this inverted part 9a ′, at its center located higher than the lower end of the peripheral wall 9.

Dans la forme de réalisation que l'on a décrite ci-dessus, l'assise 9c du support de bouteille présente une grande surface de contact avec le sol, ce qui permet de maintenir la bouteille bien stable en position droite, même si la partie 10' du support servant à retenir le fond de cette bouteille ne touche pas la surface sur laquelle repose ce support. De plus, même si le chariot ou la table sur lequel on pose la bouteille est soumis à des vibrations, ces dernières ne se transmettent à la bouteille que par la paroi périphérique inférieure 9 qui comporte l'espace A, de telle sorte que le support 7 selon cette forme de réalisation peut avoir un effet amortisseur.In the embodiment which has been described above, the seat 9c of the bottle support has a large contact surface with the ground, which makes it possible to keep the bottle very stable in an upright position, even if the part 10 'of the support serving to retain the bottom of this bottle does not touch the surface on which this support rests. In addition, even if the carriage or the table on which the bottle is placed is subjected to vibrations, the latter are transmitted to the bottle only through the lower peripheral wall 9 which comprises the space A, so that the support 7 according to this embodiment can have a damping effect.

On décrira ci-après, en se reportant aux fig. 7A et 7B, une autre forme de réalisation, selon laquelle la paroi périphérique 15 du support 7 comporte des nervures servant à augmenter sa résistance. Dans ce nouvel exemple de réalisation, il est prévu un espace entre la partie intérieure 9a et la partie extérieure 9b de la paroi périphérique inférieure 9 du support, afin d'augmenter le contact de ce dernier avec la surface sur laquelle il repose, et il est prévu en outre un certain nombre de nervures verticales 16 sur la partie extérieure 9b de la paroi 9. On notera que ces nervures 16 pourraient se trouver sur la partie intérieure 9b. Le centre de la partie 10 du support, qui est destinée à recevoir le fond d'une bouteille et qui se raccorde sur la partie rabattue vers le haut de la paroi périphérique inférieure 9, se trouve au même niveau que l'extrémité inférieure de la paroi périphérique inférieure 9.We will describe below, referring to Figs. 7A and 7B, another embodiment, according to which the peripheral wall 15 of the support 7 has ribs serving to increase its resistance. In this new embodiment, a space is provided between the inner part 9a and the outer part 9b of the lower peripheral wall 9 of the support, in order to increase the contact of the latter with the surface on which it rests, and it is also provided a number of vertical ribs 16 on the outer part 9b of the wall 9. Note that these ribs 16 could be on the inner part 9b. The center of part 10 of the support, which is intended to receive the bottom of a bottle and which is connected to the part folded up towards the top of the lower peripheral wall 9, is at the same level as the lower end of the lower peripheral wall 9.

Au contraire, dans le cas du support de bouteille 7 représenté sur les fig. BA et 8B, les nervures 16 sont plus longues et elles montent plus haut que celles de la fig. 7A. De plus, il n'y a plus de partie 10 pour retenir le fond de la bouteille, et le bord intérieur de la partie du support inclinéevers le haut et vers l'intérieur, se présente sous la forme d'une couronne circulaire ouverte 17 sur laquelle vient reposer la paroi inférieure de la bouteille. Dans une telle forme de réalisation, la partie centrale de cette paroi inférieure 6 de la bouteille peut être maintenue plus haut que l'extrémité inférieure du support 7.On the contrary, in the case of the bottle support 7 shown in FIGS. BA and 8B, the ribs 16 are longer and they rise higher than those of FIG. 7A. In addition, there is no longer any part 10 for retaining the bottom of the bottle, and the inner edge of the part of the support inclined upwards and inwards is in the form of an open circular crown 17 on which rests the bottom wall of the bottle. In such an embodiment, the central part of this lower wall 6 of the bottle can be held higher than the lower end of the support 7.

Grâce à la présence des nervures 16 dans les formes de réalisation décrites ci-dessus, la résistance du support 7 se trouve accrue, et la bouteille peut demeurer bien stable, étant donné que sa surface de contact avec le plan sur lequel elle repose est plus grande.Thanks to the presence of the ribs 16 in the embodiments described above, the resistance of the support 7 is increased, and the bottle can remain very stable, since its contact surface with the plane on which it rests is more big.

On décrira maintenant, en se reportant à la fig. 9A, une forme de réalisation selon laquelle le support 7 comporte, dans sa paroi extérieure 18, des gradins dont les diamètres sont de plus en plus petits du haut vers le bas. La partie 10, en forme de calotte sphérique, destinée à recevoir le fond d'une bouteille, se trouve à l'intérieur par rapport à la partie du support retournée vers le haut, obtenue en rabattant la paroi extérieure en gradins 18 à partir de son extrémité inférieure. La partie centrale de cette partie 10 servant à recevoir le fond d'une bouteille se trouve plus haut que l'extrémité inférieure de la paroi extérieure en gradins 18.We will now describe, referring to FIG. 9A, an embodiment according to which the support 7 comprises, in its outer wall 18, steps whose diameters are smaller and smaller from top to bottom. Part 10, in the form of a spherical cap, intended to receive the bottom of a bottle, is located inside with respect to the part of the support turned upwards, obtained by folding the outer wall in steps 18 from its lower end. The central part of this part 10 serving to receive the bottom of a bottle is higher than the lower end of the stepped outer wall 18.

Dans la forme de réalisation représentée sur la fig. 9B, la partie 19 du support 17 retournée vers le haut comporte, elle aussi, des gradins.In the embodiment shown in FIG. 9B, the part 19 of the support 17 turned upwards also comprises steps.

Dans la forme de réalisation que l'on vient de décrire, en raison de l'existence de gradins dans le support 7, la résistance aux forces extérieures dans la direction transversale peut se trouver augmentée, tout comme dans les formes de réalisation précédentes comportant des nervures. En outre, on peut obtenir un effet d'amortissement dans la direction verticale, ce qui permet d'atténuer les chocs éventuellement subis par la bouteille.In the embodiment which has just been described, due to the existence of steps in the support 7, the resistance to external forces in the transverse direction can be increased, as in the previous embodiments comprising ribs. In addition, a damping effect can be obtained in the vertical direction, which makes it possible to attenuate the shocks possibly suffered by the bottle.

On décrira ci-après, en se reportant à la fig. 10A, une nouvelle forme de réalisation, selon laquelle le support, comporte un fond plat. Dans ce cas, le support 7 se compose d'une paroi inférieure 20 qui constitue un cercle plat, d'une assise 21, de forme annulaire, entourant cette paroi de fond 20 et faisant saillie vers le bas et d'une paroi cylindrique 22 qui monte du pourtour extérieur de cette assise 21. L'extrémité supérieure de cette paroi cylindrique 22 comporte un bord de retenue 23, qui vient s'adapter fermement sur l'extrémité supérieure de la partie cylindrique de petit diamètre 5a de la bouteille. A cette fin, ce bord de retenue 23 est légèrement incliné vers le haut et vers l'intérieur.We will describe below, referring to FIG. 10A, a new embodiment, according to which the support has a flat bottom. In this case, the support 7 consists of a bottom wall 20 which constitutes a flat circle, a seat 21, of annular shape, surrounding this bottom wall 20 and projecting downwards and a cylindrical wall 22 which rises from the outer periphery of this seat 21. The upper end of this cylindrical wall 22 has a retaining edge 23, which fits firmly on the upper end of the small diameter cylindrical part 5a of the bottle. To this end, this retaining edge 23 is slightly inclined upwards and inwards.

Un tel support 7 s'obtient, comme on le voit clairement d'après la fig. 10B, en moulant par soufflage deux supports d'un seul tenant dont les parois cylindriques 22 se raccordent l'une à l'autre, puis en coupant cette pièce moulée dans sa partie centrale. Dans ce cas, l'une des poitiés de cette pièce moulée d'un seul tenant comporte une ouverture 24 destinée à l'entrée d'air comprimé et que l'on utilise au cours de l'opération de moulage par soufflage ; il convient de remarquer que,-si l'on enlève cette ouverture 24 en la coupant au ras de sa base, cela ne nuit aucunement à l'utilisation du support correspondant.Such a support 7 is obtained, as can be clearly seen from FIG. 10B, by blow molding two supports in one piece, the cylindrical walls 22 of which are connected to one another, then cutting this molded part in its central part. In this case, one of the pulleys of this integrally molded part has an opening 24 intended for the entry of compressed air and which is used during the blow molding operation; it should be noted that, if this opening 24 is removed by cutting it flush with its base, this does not in any way harm the use of the corresponding support.

Dans la forme de réalisation que l'on vient de décrire, la bouteille peut demeurer bien stable, étant donné que l'assise 21 du support forme un anneau d'assez grandes dimensions. En outre, du fait que la partie 20 du support, destinée à recevoir le fond d'une bouteille, se trouve un peu plus haut que l'assise 21, il est possible d'atténuer les chocs éventuellement subis par la bouteille. Enfin, étant donné que l'on peut réaliser deux supports par une unique opération de moulage, la fabrication est plus économique.In the embodiment which has just been described, the bottle can remain very stable, since the seat 21 of the support forms a ring of fairly large dimensions. In addition, since part 20 of the support, intended to receive the bottom of a bottle, is located a little higher than the seat 21, it is possible to reduce any shocks suffered by the bottle. Finally, since two supports can be produced by a single molding operation, the production is more economical.
