Description

La présente invention concerne une bouteille en matériau thermoplastique biorienté destinée à contenir un liquide plat dont le remplissage s'effectue à froid.The present invention relates to a bottle made of biaxially oriented thermoplastic material intended to contain a flat liquid which is filled cold.

Il est bien connu que les bouteilles en matériau thermoplastique sont de plus en plus légères ce qui crée des problèmes pour obtenir une bonne résistance mécanique de ces bouteilles tant dans le sens longitudinal que dans le sens transversal.It is well known that bottles of thermoplastic material are becoming lighter which creates problems for obtaining good mechanical strength of these bottles both in the longitudinal direction and in the transverse direction.

La Demanderesse s'est proposé de fournir une bouteille en matériau thermoplastique biorienté qui, pour faciliter sa manutention sur la chaîne de conditionnement et de distribution, a une section de forme générale carrée, des angles arrondis, un fond circulaire et qui résiste sans déformation notable, lorsqu'elle est remplie, à une force de compression appliquée selon l'axe longitudinal de la bouteille. Cette force de compression se manifeste lorsque les bouteilles sont empilées les unes au-dessus des autres lors de leur stockage et de leur transport. En outre cette bouteille doit présenter une résistance aux forces de compression transversales développées lors de la tenue en main de celle-ci pour verser le liquide qu'elle contient, sans que le débit du liquide versé soit irrégulier et provoque des éclaboussures.The Applicant has proposed to supply a bottle made of bioriented thermoplastic material which, to facilitate its handling on the packaging and distribution chain, has a generally square section, rounded angles, a circular bottom and which resists without significant deformation , when filled, at a compression force applied along the longitudinal axis of the bottle. This compressive force is manifested when the bottles are stacked one on top of the other during their storage and transport. In addition, this bottle must have a resistance to the transverse compression forces developed during the holding of the latter in order to pour the liquid which it contains, without the flow of the liquid poured being irregular and causing splashes.

L'invention a donc pour objet une bouteille en matériau thermoplastique biorienté, destinée à contenir un liquide plat, comprenant un col, un corps, un fond, une partie intermédiaire ou épaule de forme générale tronconique formant le raccordement entre le col et le corps et une partie inférieure tronconique reliant le fond au corps, bouteille dans laquelle le corps, dont la section par un plan perpendiculaire à l'axe de la bouteille a la forme générale d'un carré, comporte quatre arrondis convexes entre lesquels sont ménagées des nervures longitudinales parallèles à l'axe de la bouteille, lesdits arrondis et lesdites nervures s'étendant sur toute la hauteur du corps.The subject of the invention is therefore a bottle made of bioriented thermoplastic material, intended to contain a flat liquid, comprising a neck, a body, a bottom, an intermediate part or shoulder of generally frustoconical shape forming the connection between the neck and the body and a frustoconical lower part connecting the bottom to the body, a bottle in which the body, the section of which by a plane perpendicular to the axis of the bottle has the general shape of a square, has four convex curves between which are formed longitudinal ribs parallel to the axis of the bottle, said rounded and said ribs extending over the entire height of the body.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, faite en référence aux dessins annexés, donnés uniquement à titre d'exemple non limitatif et parmi lesquels :

Other characteristics and advantages of the invention will become apparent during the description which follows, given with reference to the appended drawings, given solely by way of nonlimiting example and among which:
  • - Fig. 1 is an elevational view of a first embodiment of a bottle according to the invention;
  • - Fig. 2 is a sectional view along line AA of the bottle shown in FIG. 1 '
  • - Fig. 3 is an elevational view of a second embodiment of a bottle according to the invention;
  • - Fig. 4 is a sectional view, along line BB of the bottle shown in FIG. 3.

La bouteille d'axe X-X, représentée aux Fig. 1 et 2, comprend un col 1, un corps 2, un fond 3 circulaire, une partie intermédiaire ou épaule 4, de forme générale tronconique, formant le raccordement entre le col 1 et le corps 2 et une partie inférieure 5 tronconique reliant le corps 2 au fond 3.The X-X axis bottle, shown in Figs. 1 and 2, includes a neck 1, a body 2, a circular bottom 3, an intermediate part or shoulder 4, of generally frustoconical shape, forming the connection between the neck 1 and the body 2 and a frustoconical lower part 5 connecting the body 2 at the bottom 3.

Le col 1 cylindrique se termine à sa partie supérieure par un filetage 6, permettant le vissage d'un bouchon d'obturation, en-­dessous duquel est ménagée une collerette 7, servant à la manutention de la bouteille lors de sa fabrication. Une partie cylindrique 8 termine le col à sa partie inférieure et le raccorde à l'épaule 4.The cylindrical neck 1 ends at its upper part with a thread 6, allowing the screwing of a closure plug, below which is a collar 7, used for handling the bottle during its manufacture. A cylindrical part 8 ends the neck at its lower part and connects it to the shoulder 4.

Le corps 2, d'axe X-X, a, en section par un plan perpendiculaire à l'axe X-X, la forme générale d'un carré dont les angles sont remplacés par des arrondis 9 convexes. Ces derniers s'étendent sur toute la hauteur de corps 2 et sont constitués par deux arcs de cercle 9a et 9b, de même rayon, reliés par une tangente commune 9c. Les centres des cercles auxquels appartiennent les arcs 9a et 9b, respectivement 10a et 10b, sont situés symétriquement deux à deux par rapport aux plans diagonaux DD′ du corps 2. Chaque arrondi s'étent selon un angle au centre C voisin de 45°.The body 2, of axis X-X, has, in section through a plane perpendicular to the axis X-X, the general shape of a square whose angles are replaced by rounded 9 convex. The latter extend over the entire height of the body 2 and are constituted by two arcs of a circle 9a and 9b, of the same radius, connected by a common tangent 9c. The centers of the circles to which the arcs 9a and 9b belong, respectively 10a and 10b, are located symmetrically two by two with respect to the diagonal planes DD ′ of the body 2. Each rounding extends at an angle to the center C close to 45 °.

Entre deux arrondis 9 successifs sont ménagées deux paires de nervures longitudinales, respectivement 11 et 12, symétriques deux à deux par rapport aux plans médians MM′ du corps 2. Ces nervures ont, vues en coupe transversale, le forme d'arcs de cercle de même rayon et sont situées en retrait par rapport aux extrémités des arrondis 9 qu'elles réunissent. Les deux nervures 12 les plus proches des plans médians MM′ sont reliées entre elles par un méplat 13 perpendiculaire aux plans médians MM′. Les nervures 11, 12 et la méplat 13 s'étendent longitudinalement, parallèlement à l'axe X-X de la bouteille sur toute la hauteur du corps 2. Ces nervures et le méplat qui les réunit procurent une bonne résistance à la compression et au flambage à la bouteille lorsque celle-ci est soumise à une charge s'exerçant selon son axe X-X, par augmentation du module d'inertie de la bouteille.Between two successive roundings 9 are formed two pairs of longitudinal ribs, respectively 11 and 12, symmetrical two by two with respect to the median planes MM ′ of the body 2. These ribs have, seen in cross section, the form of arcs of a circle of same radius and are set back relative to the ends of the rounded 9 they join. The two ribs 12 closest to the median planes MM ′ are interconnected by a flat 13 perpendicular to the median planes MM ′. The ribs 11, 12 and the flat 13 extend longitudinally, parallel to the axis XX of the bottle over the entire height of the body 2. These ribs and the flat which joins them provide good resistance to compression and buckling of the bottle when the latter is subjected to a load acting along its axis XX, by increasing the inertia module of the bottle.

Des nervures 14 en creux sont ménagées sur toute la longueur des arrondis 9 du corps 2, perpendiculairement à l'axe X-X. Dans la forme de réalisation représentée à la Fig. 1, ces nervures 14 sont au nombre de dix. Elles ont pour but d'augmenter la rigidité transversale du corps 2 de la bouteille.Hollow ribs 14 are formed over the entire length of the rounded edges 9 of the body 2, perpendicular to the axis X-X. In the embodiment shown in FIG. 1, these ribs 14 are ten in number. They are intended to increase the transverse rigidity of the body 2 of the bottle.

La partie intermédiaire ou épaule 4, de forme générale tronconique d'axe X-X, comporte quatre faces 15 planes et quatre faces 16 convexes. Les faces 15, situées dans le prolongement des nervures 11 et 12 ont la forme de triangles isocèles curvilignes dont un des sommets se raccorde à la base du col 1. Les faces 16 disposées dans le prolongement des arrondis 9 du corps 2 ont elles aussi la forme de triangles isocèles curvilignes dont l'un des sommets se raccorde à la base du col 1. Les bases des faces 16 descendent plus bas que les bases des faces 15 et se raccordent sur les arrondis du corps 2 selon des arcs de cercle 17 dont les rayons sont inférieurs à ceux des arcs de cercle 18 constituant les bases des faces 15.The intermediate part or shoulder 4, of generally frustoconical shape with an axis X-X, has four planar faces 15 and four convex faces 16. The faces 15, located in the extension of the ribs 11 and 12 have the shape of curvilinear isosceles triangles, one of the vertices of which is connected to the base of the neck 1. The faces 16 arranged in the extension of the rounded edges 9 of the body 2 also have the form of curved isosceles triangles, one of the vertices of which is connected to the base of the neck 1. The bases of the faces 16 descend lower than the bases of the faces 15 and are connected to the rounded sides of the body 2 according to arcs of circle 17 of which the radii are smaller than those of the arcs 18 forming the bases of the faces 15.

Le fond 3 est circulaire et légèrement en retrait par rapport au plan défini par l'extrémité inférieure de la bouteille.The bottom 3 is circular and slightly set back from the plane defined by the lower end of the bottle.

Enfin, la partie inférieure 5 de la bouteille qui relie le corps 2 et le fond 3 est de forme générale tronconique et s'étend jusqu'à l'extrémité inférieure des nervures 11 et 12 du corps 2.Finally, the lower part 5 of the bottle which connects the body 2 and the bottom 3 is of generally frustoconical shape and extends to the lower end of the ribs 11 and 12 of the body 2.

Dans un second mode de réalisation représenté aux Fig. 3 et 4, les arrondis 9 du corps 2 se prolongent jusqu'à proximité du fond 3 par des lobes 19 convexes ce qui permet de porter le nombre des nervures 14 transversales au nombre de onze. Comme on peut le voir à la Fig. 4, les nervures 14 s'étendent sur toute la longueur des arrondis 9 du corps 2 et les nervures 12 longitudinales contigües se raccordent entre elles suivant une arête 20 parallèle à l'axe X-X de la bouteille. Enfin, la partie intermédiaire ou épaule 4 de forme générale tronconique est composée de quatre faces 21 planes, en forme de triangles isocèles curvilignes, disposées dans le prolongement des nervures 11 et 12 longitudinales et de quatre faces 22, plans aussi, en forme de triangles isocèles curvilignes, disposées dans le prolongement des arrondis 9 du corps 2, les faces étant renforcées par des nervures 23 en creux ménagées selon les bissectrices des angles au sommet desdites faces.In a second embodiment shown in FIGS. 3 and 4, the rounded edges 9 of the body 2 are extended to near the bottom 3 by convex lobes 19 which allows the number of transverse ribs 14 to be increased to eleven. As can be seen in Fig. 4, the ribs 14 extend over the entire length of the rounded edges 9 of the body 2 and the contiguous longitudinal ribs 12 are connected together along an edge 20 parallel to the axis XX of the bottle. Finally, the intermediate part or shoulder 4 of generally frustoconical shape is composed of four planar faces 21, in the form of curvilinear isosceles triangles, arranged in the extension of the longitudinal ribs 11 and 12 and of four faces 22, also planes, in the form of triangles curvilinear isosceles, arranged in the extension of the rounded 9 of the body 2, the faces being reinforced by hollow ribs 23 formed along the bisectors of the angles at the top of said faces.

En variante, les nervures 11, 12 longitudinales peuvent, au lieu d'avoir vues en coupe la forme d'arcs de cercle, avoir la forme de segments de droite jointifs formant un profil crénelé.Alternatively, the longitudinal ribs 11, 12 may, instead of having seen in section the shape of arcs of a circle, have the shape of contiguous straight line segments forming a crenellated profile.

Ainsi, des bouteilles en polyéthylène téréphtalate (PET), fabriquées selon le premier mode de réalisation décrit ci-avant, d'une contenance de 1,5 litre, d'un poids compris entre 42 et 43 grammes, remplies d'une eau minérale plate, ont résisté en présentant une déformation longitudinale inférieure à 5 millimètres, à une charge de 45 kilogrammes appliquée suivant l'axe longitudinal X-X de la bouteille.Thus, polyethylene terephthalate (PET) bottles, manufactured according to the first embodiment described above, of a capacity of 1.5 liters, of a weight between 42 and 43 grams, filled with mineral water flat, have withstood, with a longitudinal deformation of less than 5 millimeters, a load of 45 kilograms applied along the longitudinal axis XX of the bottle.

Les avantages présentés par la bouteille selon l'invention sont les suivants :
- elle est légère ;
- elle présente une bonne résistance longitudinale à l'écrasement grâce aux nervures 11 et 12 longitudinales qui augmentent son module d'inertie. Ainsi, de telles bouteilles peuvent être empilées sans risque sur une grande hauteur pour leur stockage et leur transport ;
- la forme donnée à la partie intermédiaire ou épaule 4 permet de répartir uniformément la charge sur le corps 2, grâce notamment aux faces convexes 16 qui procurent un effet de voûte ;
- la résistance transversale nécessaire à une bonne tenue en main et à un écoulement régulier du liquide contenu, sans éclaboussement, est obtenue grâce aux nervures 14 transversales et aux arrondis 9 formés de deux arcs de cercle de même rayon reliés par une tangente commune.The advantages presented by the bottle according to the invention are the following:
- it is light;
- It has good longitudinal resistance to crushing thanks to the longitudinal ribs 11 and 12 which increase its module of inertia. Thus, such bottles can be stacked safely over a great height for their storage and transport;
- The shape given to the intermediate part or shoulder 4 makes it possible to distribute the load uniformly over the body 2, thanks in particular to the convex faces 16 which provide an arch effect;
- The transverse resistance necessary for a good grip and a regular flow of the liquid contained, without splashing, is obtained thanks to the transverse ribs 14 and the rounded 9 formed by two arcs of circle of the same radius connected by a common tangent.

L'invention ne se limite pas aux modes de réalisation décrits ci-avant, mais elle en embrasse toutes les variantes.The invention is not limited to the embodiments described above, but it embraces all variants.
