Description

EMBALLAGE METALLIQUE AVEC PARTIE TUBULAIRE  METALLIC PACKAGING WITH TUBULAR PART

La présente invention concerne le domaine des conditionnements, et en particulier celui des emballages métalliques.  The present invention relates to the field of packaging, and in particular that of metal packaging.

La conception d'un emballage doit tenir compte des contraintes liées à sa fabrication, mais aussi à ses nombreuses manipulations chez le remplisseur depuis sa réception jusqu'aux opérations finales de conditionnement.  The design of a package must take into account the constraints related to its manufacture, but also to its many manipulations in the filler from its reception to final packaging operations.

Or, les emballages, en fonction de leur matériau constitutif, sont obtenus par des techniques de fabrication qui génèrent des contraintes structurelles conduisant à la mise en œuvre d'installations de convoyage qui leur sont respectivement dédiées.  However, packaging, depending on their constituent material, are obtained by manufacturing techniques that generate structural constraints leading to the implementation of conveying facilities which are respectively dedicated to them.

A cet égard, la partie tubulaire formant le goulot des emballages (tels que les bouteilles ou les flacons) réalisés en matière plastique comporte généralement une couronne annulaire, saillante sur la circonférence, désignée « bague de transport », utile pour leur prise en charge individuelle.  In this regard, the tubular portion forming the neck of the packages (such as bottles or flasks) made of plastic generally comprises an annular ring, protruding on the circumference, designated "transport ring", useful for their individual care .

Ces emballages en matière plastique peuvent ainsi être tenus, manipulés et/ou transférés par le positionnement d'un organe de manutention en forme générale de fourchette, en appui sous cette bague de transport.  These plastic packaging can thus be held, manipulated and / or transferred by the positioning of a fork-shaped handling member, supported under this transport ring.

En pratique, pour de tels emballages plastiques, le goulot et sa bague de transport sont formés simultanément, par exemple sur une préforme (pièce semi-finie obtenue par injection) avant une finition par injection-soufflage ou par extrusion-soufflage.  In practice, for such plastic packages, the neck and its transport ring are formed simultaneously, for example on a preform (semi-finished part obtained by injection) before finishing by injection blow molding or by extrusion blow molding.

Les emballages réalisés en un matériau métallique, par exemple en acier ou en aluminium, sont dépourvus d'une telle couronne plane annulaire du fait des contraintes techniques liées au formage du métal.  Packaging made of a metallic material, for example steel or aluminum, do not have such an annular flat ring because of the technical constraints related to the forming of the metal.

La fabrication, la manutention et le remplissage de tels emballages métalliques conduisent ainsi à mettre en œuvre des moyens de manutention dédiés.  The manufacture, handling and filling of such metal packaging and lead to implement dedicated handling means.

Par conséquent, pour le remplisseur, le passage depuis des emballages en plastique vers des emballages en métal nécessite des investissements importants notamment pour la transformation des moyens de manutention.  Therefore, for the filler, the passage from plastic packaging to metal packaging requires significant investment, especially for the transformation of the handling means.

Compte tenu de ce qui précède, la demanderesse a développé une nouvelle structure d'emballage métallique qui est apte à être manipulée au sein d'une installation habituellement dédiée aux emballages plastiques.  In view of the foregoing, the Applicant has developed a new metal packaging structure that is suitable for handling in a facility usually dedicated to plastic packaging.

Pour cela, l'emballage métallique selon l'invention comporte une partie tubulaire définissant un axe longitudinal, laquelle partie tubulaire comporte une structure annulaire monobloc composée d'une ou plusieurs moulures qui sont ménagées sur un plan s'étendant perpendiculairement audit axe longitudinal et sur la circonférence de ladite partie tubulaire, pour former une surface inférieure annulaire contre laquelle un organe pour la manutention est destiné à venir prendre appui.  For this, the metal package according to the invention comprises a tubular part defining a longitudinal axis, which tubular portion comprises a monobloc annular structure composed of one or more moldings which are formed on a plane extending perpendicularly to said longitudinal axis and on the circumference of said tubular portion, to form an annular bottom surface against which a body for handling is intended to come to bear.

La ou les moulures sont ménagées avantageusement en saillie vers l'intérieur (« entrant ») et/ou vers l'extérieur (« sortant ») de la partie tubulaire. Selon une forme de réalisation particulière, la structure annulaire monobloc comporte une moulure annulaire continue s'étendant sur toute la circonférence de la partie tubulaire. Dans ce cas, la moulure annulaire continue présente une forme de nervure ouverte, s'ouvrant vers l'intérieur ou vers l'extérieur de la partie tubulaire ; de manière alternative, cette moulure annulaire continue présente une forme de nervure fermée, constituant une collette monobloc ménagée en saillie vers l'extérieur qui est formée de deux couronnes annulaires planes en appui l'une sur l'autre et reliées par une ligne de pliage périphérique. The one or more moldings are advantageously protruding inwardly ("inward") and / or outwardly ("outgoing") from the tubular portion. According to a particular embodiment, the one-piece annular structure comprises a continuous annular molding extending over the entire circumference of the tubular portion. In this case, the continuous annular molding has an open rib shape, opening towards the inside or towards the outside of the tubular part; alternatively, this continuous annular molding has a closed rib shape, constituting a one-piece collar projecting outwardly which is formed of two planar annular rings bearing against one another and connected by a fold line peripheral.

Selon une autre forme de réalisation, la structure annulaire monobloc comporte au moins une variation de courbure dans le plan perpendiculaire à l'axe longitudinal passant par ladite structure annulaire.  According to another embodiment, the one-piece annular structure comprises at least one variation of curvature in the plane perpendicular to the longitudinal axis passing through said annular structure.

Cette structure annulaire monobloc présente ainsi des discontinuités de courbure, avec avantageusement une variation de la distance radiale horizontale autour de l'axe horizontal.  This monobloc annular structure thus has discontinuities of curvature, with advantageously a variation of the horizontal radial distance around the horizontal axis.

Cette forme de réalisation vise à introduire, en un ou plusieurs points de la circonférence de la partie tubulaire, une discontinuité géométrique au niveau de la structure annulaire monobloc, en particulier une discontinuité géométrique dans la moulure, dans l'une au moins des moulures ou entre deux moulures, qui permet de consolider cette partie de l'emballage et d'augmenter de manière significative la résistance à l'effort vertical.  This embodiment aims to introduce, at one or more points of the circumference of the tubular part, a geometrical discontinuity at the level of the monobloc annular structure, in particular a geometrical discontinuity in the molding, in at least one of the moldings or between two moldings, which consolidates this part of the package and significantly increase the resistance to vertical effort.

Cette discontinuité peut prendre la forme de courbes plus ou moins complexes, et préférentiellement de tronçons de partie tubulaire non moulurés (ou segments verticaux) s'étendant dans la continuité de la forme des parties sus-jacente et sous-jacente de la partie tubulaire par rapport à cette structure annulaire monobloc.  This discontinuity can take the form of more or less complex curves, and preferably unmolded tubular portion portions (or vertical segments) extending in the continuity of the shape of the overlying and underlying portions of the tubular portion by relative to this monobloc ring structure.

En d'autres termes, la section initiale de la partie tubulaire est déformée de sorte à ménager la ou les moulures destinées à constituer la structure annulaire monobloc.  In other words, the initial section of the tubular portion is deformed so as to spare the molding or moldings intended to constitute the monobloc annular structure.

Dans ce cas, la structure annulaire monobloc comprend au moins une moulure s'étendant sur une partie seulement de la circonférence de la partie tubulaire.  In this case, the one-piece annular structure comprises at least one molding extending over only a portion of the circumference of the tubular portion.

Cette structure annulaire monobloc comporte avantageusement plusieurs moulures qui sont réparties sur la circonférence de la partie tubulaire, de manière régulière ou non-régulière (homogène ou non-homogène).  This monobloc annular structure advantageously comprises several moldings which are distributed over the circumference of the tubular part, in a regular or non-regular manner (homogeneous or non-homogeneous).

De préférence, la structure annulaire monobloc comporte des moulures qui sont chacune saillantes vers l'extérieur, et qui sont régulièrement réparties sur la circonférence de la partie tubulaire, ceci dans le plan perpendiculaire à l'axe longitudinal passant par ladite structure annulaire.  Preferably, the one-piece annular structure comprises moldings which are each outwardly projecting, and which are evenly distributed over the circumference of the tubular part, in the plane perpendicular to the longitudinal axis passing through said annular structure.

De préférence, la structure annulaire monobloc comporte une ou plusieurs encoches, ménagées sur la moulure et/ou sur l'une au moins des moulures et/ou séparant deux moulures ; ces encoches présentent avantageusement un axe vertical ou au moins approximativement vertical, et sont formées avantageusement par un tronçon non-mouluré de la partie tubulaire.  Preferably, the one-piece annular structure comprises one or more notches, formed on the molding and / or on at least one of the moldings and / or separating two moldings; these notches advantageously have a vertical axis or at least approximately vertical, and are advantageously formed by an unmolded section of the tubular portion.

De préférence, une encoche est ménagée entrante pour une ou des moulures sortantes ; une encoche est ménagée sortante pour une ou des moulures entrantes. Le fond de l'encoche ou de l'une au moins des encoches s'étend dans la circonférence, ou au moins approximativement dans la circonférence, de la partie tubulaire. Preferably, a notch is formed incoming for one or more outgoing moldings; a notch is formed outgoing for one or more moldings incoming. The bottom of the notch or at least one of the notches extends in the circumference, or at least approximately in the circumference, of the tubular portion.

Selon une forme de réalisation particulière, l'emballage métallique consiste en un récipient (par exemple une bouteille) comportant un col formant ladite partie tubulaire ; et ce col est terminé par un goulot muni d'une partie supérieure pour la réception d'un bouchon et d'une partie inférieure comportant la structure annulaire monobloc.  According to a particular embodiment, the metal package consists of a container (for example a bottle) having a neck forming said tubular portion; and this neck is terminated by a neck provided with an upper part for receiving a cap and a lower part having the monobloc annular structure.

L'invention porte encore sur un procédé pour la fabrication d'un emballage métallique tel que défini ci-dessus, lequel procédé consiste :  The invention further relates to a process for the manufacture of a metal package as defined above, which process comprises:

(a) à fabriquer la partie tubulaire dudit emballage, puis  (a) to manufacture the tubular portion of said package, and

(b) à déformer localement ladite partie tubulaire pour constituer la structure annulaire monobloc composée d'une ou plusieurs moulures.  (b) locally deforming said tubular portion to form the one-piece annular structure composed of one or more moldings.

Les figures 1 et 2 représentent une partie d'un emballage métallique.  Figures 1 and 2 show a part of a metal package.

Un tel emballage métallique est par exemple réalisé en aluminium ou en acier.  Such a metal package is for example made of aluminum or steel.

Cet emballage métallique consiste avantageusement en un récipient ou un contenant, destiné à recevoir par exemple un produit liquide (notamment des boissons), pâteux ou solide (notamment des poudres ou granulés).  This metal package advantageously consists of a container or a container, intended to receive for example a liquid product (including drinks), pasty or solid (including powders or granules).

Un tel emballage métallique consiste par exemple en une bouteille, un flacon ou un bidon.  Such a metal package consists for example of a bottle, a bottle or a can.

Cet emballage comprend avantageusement un corps ou ventre (non représenté), surmonté par une partie tubulaire 1 (figures 1 et 2) constituant un col, terminée par un goulot 2 débouchant par une ouverture terminale 3.  This package advantageously comprises a body or belly (not shown), surmounted by a tubular portion 1 (FIGS. 1 and 2) constituting a neck, terminated by a neck 2 opening through a terminal opening 3.

La partie tubulaire 1 présente un axe longitudinal 1 ', ici orienté verticalement.  The tubular portion 1 has a longitudinal axis 1 ', here oriented vertically.

Cette partie tubulaire 1 est constituée par une paroi métallique monobloc 4 qui définit sa circonférence et qui délimite un conduit intérieur Ç_(figure 3).  This tubular portion 1 is constituted by a one-piece metal wall 4 which defines its circumference and which delimits an inner conduit C (Figure 3).

La section horizontale de cette partie tubulaire 1 , perpendiculairement à l'axe longitudinal 1 ', est ici de forme circulaire, mais elle pourrait tout aussi bien être ovale, rectangulaire ou carrée par exemple.  The horizontal section of this tubular portion 1, perpendicular to the longitudinal axis 1 ', is here circular in shape, but it could equally well be oval, rectangular or square for example.

L'extrémité supérieure 5 de la partie tubulaire 1 est constituée ici par un ourlet périphérique orienté vers l'extérieur, délimitant l'ouverture terminale 3 (figures 1 et 2).  The upper end 5 of the tubular portion 1 is constituted here by an outwardly oriented peripheral hem defining the end opening 3 (Figures 1 and 2).

Du côté de cette extrémité supérieure 5, une partie supérieure 2a du goulot 2 comporte des moyens pour la réception d'un bouchon (non représenté), en l'occurrence un filet hélicoïdal 6.  On the side of this upper end 5, an upper portion 2a of the neck 2 comprises means for receiving a plug (not shown), in this case a helical thread 6.

A distance de cette même extrémité supérieure 5, une partie inférieure 2b du goulot 2 (directement sous-jacente de la partie supérieure 2a) comporte une structure annulaire monobloc 10 composée d'une moulure 1 1 pour former une surface inférieure annulaire 12 contre laquelle un organe de manutention peut venir prendre appui.  At a distance from this same upper end 5, a lower portion 2b of the neck 2 (directly underlying the upper part 2a) comprises a monobloc annular structure 10 composed of a molding 1 1 to form an annular lower surface 12 against which a handling device can come to support.

Cet organe de manutention (non représenté) présente avantageusement une forme de fourchette, du type rencontré classiquement dans le domaine de la manutention de bouteilles plastiques munies d'une bague de transport.  This handling member (not shown) advantageously has a fork shape, of the type conventionally encountered in the field of the handling of plastic bottles provided with a transport ring.

A cet égard, la moulure 1 1 est ménagée sur un plan 13 (figure 2) s'étendant perpendiculairement à l'axe longitudinal 1 ' précité et sur la circonférence de la partie tubulaire 1 .  In this regard, the molding 1 1 is formed on a plane 13 (Figure 2) extending perpendicularly to the longitudinal axis 1 'above and on the circumference of the tubular portion 1.

Par « moulure », on entend notamment un nervurage dans la paroi métallique monobloc 4 (désigné couramment en anglais sous le terme de « bead »), en creux ou en relief, obtenu par exemple par frappe ou par repoussage.  By "molding" is meant in particular a ribbing in the one-piece metal wall 4 (commonly referred to in English as "bead"), recessed or raised, obtained for example by striking or embossing.

La moulure 1 1 est continue, s'étendant sur toute la circonférence de la partie tubulaire 1 . Tel qu'illustré par les figures 1 à 3, la moulure annulaire continue 1 1 est ici ménagée en saillie vers l'extérieur de la partie tubulaire 1 . The molding 1 1 is continuous, extending over the entire circumference of the tubular portion 1. As illustrated by FIGS. 1 to 3, the continuous annular molding 1 1 is here provided protruding outwardly from the tubular part 1.

Comme visible sur la figure 3, cette moulure annulaire continue 1 1 présente une forme de nervure ouverte, s'ouvrant vers l'intérieur de la partie tubulaire 1 .  As can be seen in FIG. 3, this continuous annular molding 11 has an open rib shape, opening towards the inside of the tubular part 1.

La section verticale de cette moulure annulaire continue 1 1 est identique ou au moins approximativement identique sur sa circonférence, sans rupture géométrique (figure 3).  The vertical section of this continuous annular molding 11 is identical or at least approximately identical on its circumference, without geometrical rupture (FIG. 3).

Selon la figure 3, cette section verticale est ici de forme courbe, par exemple en demi- cercle ou demi-ovale, dont la convexité est orientée vers l'extérieur.  According to Figure 3, this vertical section is here of curved shape, for example in a semi-circle or half-oval, whose convexity is oriented outwards.

La surface inférieure annulaire 12 est ainsi formée par, approximativement, la moitié inférieure de cette moulure annulaire continue 1 1 .  The annular lower surface 12 is thus formed by approximately the lower half of this continuous annular molding 11.

La figure 4 représente une variante de réalisation d'une moulure annulaire continue 1 1 constitutive d'une structure annulaire monobloc 10.  FIG. 4 shows an alternative embodiment of a continuous annular molding 1 1 constituting a monobloc annular structure 10.

La section de cette moulure annulaire continue 1 1 se compose ici de deux tronçons : The section of this continuous annular molding 1 1 consists here of two sections:

- un tronçon supérieur incliné 14, divergeant par rapport à l'axe longitudinal 1 ' du haut vers le bas, et an inclined upper section 14, diverging with respect to the longitudinal axis 1 'from the top to the bottom, and

- un tronçon inférieur horizontal 15, s'étendant perpendiculairement par rapport à l'axe longitudinal 1 ' et dont la face inférieure constitue la surface inférieure annulaire 12 pour la manutention.  - A horizontal lower section 15, extending perpendicularly to the longitudinal axis 1 'and whose lower face is the annular lower surface 12 for handling.

En d'autres termes, la moulure annulaire continue 1 1 se compose d'une partie supérieure tronconique et d'une partie inférieure en forme de couronne horizontale.  In other words, the continuous annular molding 1 1 consists of a frustoconical upper part and a lower part in the form of a horizontal ring.

Selon encore une autre forme de réalisation représentée sur la figure 5, la moulure annulaire continue 1 1 présente une forme de nervure fermée, constituant une collette monobloc ménagée en saillie vers l'extérieur.  According to yet another embodiment shown in Figure 5, the continuous annular molding 1 1 has a closed rib shape, constituting a monobloc collar provided projecting outwardly.

Une telle moulure annulaire continue 1 1 , encore dénommée « moulure compressée » ou « compressed bead », est formée de deux couronnes annulaires planes 16 en appui l'une sur l'autre, l'une inférieure formant la surface inférieure annulaire 12 pour la manutention et l'autre supérieure, qui sont reliées par une ligne de pliage périphérique 17.  Such a continuous annular molding 1 1, also called "compressed molding" or "compressed bead", is formed of two planar annular rings 16 resting on one another, the lower one forming the annular bottom surface 12 for the handling and the other upper, which are connected by a peripheral fold line 17.

Les figures 6 à 8 représentent une autre forme de réalisation de l'invention dans laquelle la structure annulaire monobloc 10 comporte, sur la circonférence de la partie tubulaire 1 , au moins une variation de courbure dans le plan 13 perpendiculaire à l'axe longitudinal 1 ' passant par ladite structure annulaire 10.  Figures 6 to 8 show another embodiment of the invention in which the one-piece annular structure 10 comprises, on the circumference of the tubular portion 1, at least one variation of curvature in the plane 13 perpendicular to the longitudinal axis 1 passing through said annular structure 10.

Une telle forme de réalisation permet de consolider le goulot 2 de l'emballage, et d'augmenter de manière significative la résistance à l'effort vertical au niveau de cette structure annulaire monobloc 10.  Such an embodiment makes it possible to consolidate the neck 2 of the package, and to significantly increase the resistance to the vertical force at the level of this monobloc annular structure 10.

A cet effet, la structure annulaire monobloc 10 comprend une « moulure discontinue » For this purpose, the one-piece annular structure 10 comprises a "discontinuous molding"

1 1 s'étendant sur la circonférence de la partie tubulaire 1 . 1 1 extending over the circumference of the tubular portion 1.

Cette structure annulaire monobloc 10 comporte ainsi plusieurs moulures 1 1 distinctes qui sont réparties, de manière homogène ou régulière, sur la circonférence de la partie tubulaire 1 . En l'occurrence, ces moulures 1 1 s'étendent chacune sur une partie de la circonférence de la partie tubulaire 1 . This one-piece annular structure 10 thus comprises a plurality of separate moldings January 1 which are distributed, homogeneously or evenly, around the circumference of the tubular part 1. In this case, these moldings 1 1 each extend over a portion of the circumference of the tubular portion 1.

La structure annulaire monobloc 10 comporte ici trois moulures 1 1 , s'étendant de manière générale chacune sur un secteur angulaire horizontal de l'ordre de 5° à 120° , et de préférence chacune sur un secteur angulaire horizontal de l'ordre de 60° à 1 10° .  The one-piece annular structure 10 here comprises three moldings 1 1, each extending generally over a horizontal angular sector of the order of 5 ° to 120 °, and preferably each on a horizontal angular sector of the order of 60 ° to 1 10 °.

Ces moulures 1 1 sont chacune saillantes vers l'extérieur, et elles sont régulièrement réparties sur la circonférence de la partie tubulaire 1 et dans le plan 13 perpendiculaire à l'axe longitudinal 1 '.  These moldings January 1 are each protruding outwardly, and they are evenly distributed over the circumference of the tubular portion 1 and in the plane 13 perpendicular to the longitudinal axis 1 '.

Les moulures 1 1 forment ensemble la surface inférieure d'appui 12 ; cette dernière est ici discontinue, formée par la surface inférieure de ces différentes moulures 1 1 .  The moldings 1 1 together form the lower bearing surface 12; the latter is here discontinuous, formed by the lower surface of these various moldings January 1.

La section verticale de ces moulures 1 1 peut être adaptée à façon, par exemple courbe ou diédrique tel que décrit ci-dessus.  The vertical section of these moldings January 1 may be adapted, for example curve or dihedral as described above.

Ces moulures 1 1 sont séparées, deux à deux, par une encoche 20 consistant en un tronçon non-mouluré de la partie tubulaire 1 (ici au nombre de trois).  These moldings January 1 are separated, in pairs, by a notch 20 consisting of an unmolded portion of the tubular portion 1 (here three in number).

Ces tronçons non-moulurés 20 forment ainsi des zones de rigidification pour la structure annulaire monobloc 10 à rencontre des efforts verticaux.  These unmolded sections 20 thus form stiffening zones for the one-piece annular structure 10 against vertical forces.

Chaque tronçon non-mouluré 20 consiste en un segment du goulot 2 (ou de la partie tubulaire 1 ), s'étendant selon un axe vertical 20' (figure 8) et dans la continuité de la section des parties directement sus-jacente et sous-jacente de ce goulot 2 (sans discontinuité ou rupture de la section).  Each unmolded section 20 consists of a segment of the neck 2 (or of the tubular part 1), extending along a vertical axis 20 '(FIG. 8) and in the continuity of the section of the directly overlying portions and under -cente of this neck 2 (without discontinuity or rupture of the section).

Ces tronçons non-moulurés 20 s'étendent ainsi dans la circonférence de la partie tubulaire 1 .  These unmolded sections 20 thus extend in the circumference of the tubular portion 1.

De même, le fond 20a de chaque encoche 20 s'étend ainsi avantageusement dans la circonférence de la partie tubulaire 1 .  Similarly, the bottom 20a of each notch 20 thus advantageously extends in the circumference of the tubular portion 1.

Chaque encoche 20 est délimitée latéralement par les extrémités 20b en regard de deux moulures 1 1 juxtaposées.  Each notch 20 is delimited laterally by the ends 20b opposite two moldings January 1 juxtaposed.

Sur une section horizontale, les extrémités 20b de chaque encoche 20 s'étendent par exemple parallèlement l'une par rapport à l'autre, ou divergent vers la périphérie, tel qu'illustré par la suite en relation avec la figure 16. Chaque encoche 20 peut encore présenter une section en arc de cercle.  On a horizontal section, the ends 20b of each notch 20 extend for example parallel to one another, or diverge towards the periphery, as illustrated below in connection with FIG. 16. Each notch 20 may still have a section in an arc.

Le procédé pour la fabrication de l'emballage métallique selon l'invention, comprend avantageusement les étapes suivantes :  The process for the manufacture of the metal package according to the invention advantageously comprises the following steps:

(a) la fabrication de la partie tubulaire 1 de l'emballage, puis  (a) the manufacture of the tubular part 1 of the package, then

(b) le formage de la structure annulaire monobloc 10 dans ladite partie tubulaire 1 , pour constituer la ou les moulures 1 1 , par exemple sous la forme d'une opération de mise en forme locale et discontinue des différentes moulures.  (b) forming the monobloc annular structure 10 in said tubular portion 1, to form the moldings 1 1, for example in the form of a local and discontinuous shaping operation of the various moldings.

Les figures 9 à 14 représentent des exemples de variantes de réalisation de cette structure annulaire monobloc 10 comportant plusieurs moulures 1 1 orientées vers l'extérieur, et séparées deux à deux par un tronçon non-mouluré 20 de la partie tubulaire 1 . Sur ces figures, les structures annulaires monoblocs 10 comportent respectivement :FIGS. 9 to 14 show examples of alternative embodiments of this monobloc annular structure 10 comprising a plurality of outwardly oriented moldings 11, separated in pairs by an unmolded section 20 of the tubular part 1. In these figures, the one-piece annular structures 10 respectively comprise:

- Figure 9 : trois moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 60° à 100 ° , séparées par des tronçons non-moulués 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 20° à 60 ° ; - Figure 9: three moldings 1 1 each extending over a horizontal angular sector of the order of 60 ° to 100 °, separated by unmolded sections 20 each extending over a horizontal angular sector of the order of 20 ° to 60 °;

- Figure 10 : six moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 30 ° à 55° , séparées par des tronçons non-mouluré 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 5° à 30° ; - Figure 10: six moldings 1 1 each extending over a horizontal angular sector of the order of 30 ° to 55 °, separated by unmolded sections 20 each extending over a horizontal angular sector of the order of 5 ° to 30 °;

- Figure 1 1 : trois moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 30 ° à 60° , séparées par des tronçons non-mouluré 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 60° à 90 ° ;  - Figure 1 1: three moldings 1 1 each extending over a horizontal angular sector of the order of 30 ° to 60 °, separated by non-molded sections 20 each extending over a horizontal angular sector of the order from 60 ° to 90 °;

- Figure 12 : six moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 30 ° à 50° , séparées par des tronçons non-mouluré 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 10° à30° ;  - Figure 12: six moldings 1 1 each extending over a horizontal angular sector of the order of 30 ° to 50 °, separated by unmolded sections 20 each extending over a horizontal angular sector of the order of 10 ° to 30 °;

- Figure 13 : trois moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 10 ° à 30° , séparées par des tronçons non-mouluré 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 90° à 1 10° ;  - Figure 13: three moldings 1 1 each extending over a horizontal angular sector of the order of 10 ° to 30 °, separated by unmolded sections 20 each extending over a horizontal angular sector of the order of 90 ° to 110 °;

- Figure 14 : six moulures 1 1 s'étendant chacune sur un secteur angulaire horizontal de l'ordre de 10 ° à 30° , séparées par des tronçons non-mouluré 20 s'étendant chacun sur un secteur angulaire horizontal de l'ordre de 30° à 50 ° .  - Figure 14: six moldings 1 1 each extending over a horizontal angular sector of the order of 10 ° to 30 °, separated by unmolded sections 20 each extending over a horizontal angular sector of the order of 30 ° to 50 °.

La figure 15 montre encore, vue de dessus, une structure annulaire périphérique 10 comportant plusieurs moulures 1 1 séparées par des encoches 20.  FIG. 15 still shows, seen from above, a peripheral annular structure 10 comprising several moldings 1 1 separated by notches 20.

Sur cette figure 15, on peut voir que le fond 20a de chaque encoche 20 s'étend avantageusement dans la circonférence du goulot 2.  In this figure 15, it can be seen that the bottom 20a of each notch 20 advantageously extends in the circumference of the neck 2.

De manière alternative, ce fond 20a de chaque encoche entrante 20 peut s'étendre : - dans un premier cas, dans l'encombrement annulaire défini par les moulures 1 1 et à distance de la circonférence du goulot 2, correspondant en une sorte d'emboutissage partiel, tel que représenté par le fond désigné par le repère 20a1_, ou  Alternatively, this bottom 20a of each incoming notch 20 may extend: - in a first case, in the annular space defined by the moldings 1 1 and at a distance from the circumference of the neck 2, corresponding in a kind of partial stamping, as represented by the bottom designated by the reference 20a1_, or

- dans un second cas, dans le volume interne défini par la partie tubulaire 1 , tel que représenté par le fond désigné par le repère 20a2.  in a second case, in the internal volume defined by the tubular part 1, as represented by the bottom designated by the reference 20a2.

Dans le premier cas, la structure annulaire monobloc 10 consiste en une sorte de moulure annulaire continue 1 1 dans laquelle est ménagée une pluralité d'encoches 20.  In the first case, the one-piece annular structure 10 consists of a kind of continuous annular molding 1 1 in which is formed a plurality of notches 20.

Dans le second cas, la structure annulaire monobloc comporte une alternance de moulures en saillie vers l'intérieur et vers l'extérieur ; on obtient ainsi une combinaison de moulures entrantes/sortantes par rapport à la partie tubulaire.  In the second case, the one-piece annular structure comprises an alternation of moldings projecting inwards and outwards; thus obtaining a combination of incoming / outgoing moldings with respect to the tubular portion.

La fabrication d'une telle structure annulaire monobloc comprend avantageusement - une opération de formage d'une moulure annulaire continue, suivie - d'une opération de formage de la ou des encoches, par exemple par emboutissage.  The manufacture of such a monobloc annular structure advantageously comprises - a forming operation of a continuous annular molding, followed by - an operation of forming the one or more notches, for example by stamping.

On obtient ainsi une sorte de moulure annulaire continue 1 1 qui est interrompue localement, et sur sa circonférence, par des encoches 20. Ces encoches 20, vues de dessus, peuvent présenter tout autre forme obtenue par un outillage adapté, tel qu'illustré sur la figure 16. This gives a kind of continuous annular molding 1 1 which is interrupted locally, and on its circumference, by notches 20. These notches 20, viewed from above, may have any other form obtained by a suitable tool, as illustrated in FIG. 16.

Ainsi, ces encoches 20 peuvent présenter par exemple une forme rectangulaire (A ou B), une forme trapézoïdale (C ou D) ou une forme en arc de cercle (E).  Thus, these notches 20 may have for example a rectangular shape (A or B), a trapezoidal shape (C or D) or an arcuate shape (E).

La figure 17 montre une variante de réalisation de l'invention, dans laquelle la structure annulaire monobloc 10 comprend une moulure 1 1 consistant en une nervure ouverte vers l'extérieur.  FIG. 17 shows an alternative embodiment of the invention, in which the one-piece annular structure 10 comprises a bead 11 consisting of an open-out rib.

Cette moulure 1 1 est ici en forme d'une moulure annulaire continue, générant une surface inférieure d'appui 12. Dans des variations de réalisation on peut envisager encore une pluralité de moulures ouvertes vers l'extérieur, qui sont disposées dans le même plan perpendiculaire à l'axe du goulot et qui sont séparées par des tronçons non moulurés ou par des moulures en saillie vers l'extérieur.  This molding 1 1 is here in the form of a continuous annular molding, generating a lower bearing surface 12. In variations of embodiment it is possible to envisage a plurality of outwardly open moldings, which are arranged in the same plane perpendicular to the axis of the neck and which are separated by unmolded sections or outwardly projecting moldings.

De manière générale, l'emballage métallique selon l'invention est simple à manutentionner, notamment sur une installation dédiée habituellement pour la manutention d'emballages en plastique.  In general, the metal packaging according to the invention is simple to handle, especially on a dedicated facility usually for the handling of plastic packaging.
