Abstract

The pourer neck (5) is mounted on the end of a flexible spout (6) which can be retracted inside the container (2) or pulled out in a deployed position for pouring, and is closed by a cap (11). The neck has an inner seal (15) which is connected to it by a zone (16) of reduced resistance and is equipped with a projecting cylinder (17) which has a threaded outer surface to engage with a matching inner surface on a cylinder (9) projecting inwards from the cap (11). The threaded surfaces of the two cylinders are left-handed, so that when the cap is unscrewed the threaded joint tightened, and one sufficient force is applied to it the zone of reduced resistance breaks and the seal and cap can be removed. <IMAGE>

Description

La présente invention concerne le conditionnement de produits divers, plus particulièrement liquides, pulvérulents, voire pâteux, dans des récipients destinés à être utilisés pour la fonction première de conditionnement d'une quantité déterminée de produits et pour une fonction seconde de distribution d'un tel produit.The present invention relates to the packaging of various products, more particularly liquid, powdery or even pasty, in containers intended to be used for the primary function of packaging a determined quantity of products and for a secondary function of dispensing such a product. product.

L'invention concerne plus spécifiquement les bouchons-verseurs qui sont adaptés sous forme fermée sur des récipients, avant ou après la phase de remplissage.The invention relates more specifically to pouring caps which are adapted in closed form on containers, before or after the filling phase.

La technique antérieure connaît des bouchons-verseurs qui sont composés d'un col épanoui ou non et sur lequel peut être montée ou démontée une capsule de fermeture. Pour la fonction de versage, de tels bouchons peuvent être considérés comme particulièrement bien adaptés, au point que la technique ne semble pas receler de développements ou propositions nouvelles.The prior art knows pouring caps which are composed of a blown neck or not and on which can be mounted or dismounted a closure cap. For the pouring function, such plugs can be considered to be particularly well suited, to the point that the technique does not seem to harbor any new developments or proposals.

De tels bouchons-verseurs doivent aussi nécessairement répondre à une autre obligation qui est celle de pouvoir assurer, de façon étanche et inviolable, la fermeture du récipient, de manière à fournir à l'utilisateur, lors de la première mise en service, une certitude que le bouchon n'a fait l'objet d'aucune tentative, réussie ou non, d'ouverture frauduleuse ou de violabilité.Such pouring caps must also necessarily meet another obligation which is that of being able to ensure, in a sealed and inviolable manner, the closure of the container, so as to provide the user, during the first start-up, with certainty that the cap has not been the subject of any attempt, successful or not, to fraudulent opening or violability.

A proprement parler, une telle fonction n'est pas assurée par le bouchon-verseur, mais par des moyens ajoutés qu'il convient de détruire par tout moyen approprié.Strictly speaking, such a function is not ensured by the pouring plug, but by added means which should be destroyed by any suitable means.

Dans le cas d'application de bouchons-verseurs adaptés de façon démontable sur des récipients, généralement à usage unique, une telle méthode s'est avérée peu convenable et a fait naître des propositions de substitution consistant à doter le bouchon-verseur d'une membrane d'étanchéité, operculant la section de passage pour garantir l'inviolabilité du contenant.In the case of application of pouring plugs which can be dismantled and adapted to containers, generally for single use, such a method has proved unsuitable and has given rise to alternative proposals consisting in providing the pouring plug with a sealing membrane, sealing the passage section to guarantee the inviolability of the container.

Les propositions connues font intervenir une membrane qui se caractérise par la nécessité de développer un effort d'arrachage, relativement élevé, créant un inconfort d'utilisation, voire, dans certains cas, une impossibilité d'ouverture manuelle sans recourir à un outillage adapté ou de fortune.The known proposals involve a membrane which is characterized by the need to develop a lifting force, relatively high, creating discomfort in use, or even, in some cases, impossibility of manual opening without using suitable tools or of Fortune.

La fonction d'arrachage ou d'ouverture est généralement telle qu'elle provoque aussi, lors de la déchirure et par la mise en relation du milieu interne avec le milieu externe, des projections plus ou moins importantes, qui ont généralement un effet polluant certain.The tear-off or opening function is generally such that it also provokes, during the tearing and by the connection of the internal medium with the medium external, more or less significant projections, which generally have a certain polluting effect.

De tels inconvénients sont encore plus pénalisants lorsque le bouchon-verseur présente un diamètre d'ouverture faible, rendant encore plus délicat, voire problématique, l'accès à la membrane, soit directement, soit par l'intermédiaire d'un élément de préhension qui lui est associé.Such drawbacks are even more penalizing when the pouring plug has a small opening diameter, making it even more delicate, even problematic, access to the membrane, either directly or via a gripping element which associated with it.

Pour tenter de supprimer les inconvénients ci-dessus, il pourrait être considéré que la solution à adopter consiste à réaliser la membrane ou l'opercule d'inviolabilité avec une épaisseur faible, de telle sorte que l'effort d'arrachage reste modeste. Pour obtenir un tel effet, il est nécessaire de réaliser la membrane avec une épaisseur de quelques centièmes de millimètres qui, en fonction des matières mises en oeuvre, fait naître le risque de micro-perforations préjudiciables au caractère hermétique du conditionnement devant être réalisé. Un tel risque est notamment largement à considérer lorsque le bouchon-verseur est réalisé par moulage en matière plastique, tel que, par exemple, en polyéthylène basse densité.In an attempt to eliminate the above drawbacks, it could be considered that the solution to be adopted consists in making the membrane or the tamper-evident seal with a small thickness, so that the tear-off effort remains modest. To obtain such an effect, it is necessary to produce the membrane with a thickness of a few hundredths of a millimeter which, depending on the materials used, gives rise to the risk of micro-perforations detrimental to the hermetic nature of the packaging to be produced. Such a risk is especially largely to be considered when the pouring plug is made by molding in plastic material, such as, for example, in low density polyethylene.

L'invention a pour objet un nouveau bouchon-verseur dont la structure générale peut être qualifiée comme issue de l'art antérieur, mais qui est pourvue de moyens particuliers, permettant d'assumer la fonction d'inviolabilité lors de la première utilisation, en n'exigeant de la part de l'utilisateur qu'un faible effort physique pour le déchirage de l'opercule qui est, en outre, à même de garantir une ouverture sans risque de projection du contenant interne au récipient.The subject of the invention is a new pouring plug, the general structure of which can be qualified as coming from the prior art, but which is provided with particular means, making it possible to assume the function of inviolability during the first use, in requiring only a slight physical effort on the part of the user to tear off the cover which is, moreover, capable of guaranteeing an opening without risk of projection from the internal container to the container.

Un autre objet de l'invention est de permettre la réalisation d'un bouchon-verseur entièrement en matière plastique moulée, à base de deux éléments constitutifs qui peuvent être montés et assemblés de manière automatique, pour constituer un ensemble garantissant lors de la première utilisation une fonction d'information d'inviolabilité indubitable pour l'utilisateur.Another object of the invention is to allow the production of a pouring stopper made entirely of molded plastic, based on two constituent elements which can be assembled and assembled automatically, to constitute an assembly guaranteeing during the first use. an undeniable inviolability information function for the user.

Un autre objet de l'invention est de garantir la réalisation d'un bouchon-verseur en matière plastique dont le moyen, operculant la section de passage du bouchon-verseur, est à même d'assumer une fonction de fermeture étanche, exempte de micro-trous ou micro-perforations, sans que sa déchirure ou son ouverture n'exige de la part de l'utilisateur une dépense physique importante avec des risques de projection.Another object of the invention is to guarantee the production of a plastic pouring plug, the means of which, sealing the passage section of the pouring plug, is capable of assuming a sealed closure function, free of micro -holes or micro-perforations, without its tearing or opening requiring significant physical expenditure on the part of the user with risks of projection.

Un autre objet de l'invention est d'offrir à l'utilisateur, après une première ouverture, une possibilité de refermeture étanche, efficace, s'opposant à tout échange entre le milieu interne du contenant et le milieu extérieur.Another object of the invention is to offer the user, after a first opening, a possibility of tight, effective reclosing, opposing any exchange between the internal medium of the container and the external medium.

Pour atteindre les objectifs ci-dessus, l'objet de l'invention est caractérisé en ce que

  • le col est obturé intérieurement par un opercule lié audit col par une zone de moindre résistance,
  • un appendice cylindrique s'élève de façon centrée à partir de l'opercule à l'intérieur du col,
  • le capuchon est prévu pour coopérer, en position de fermeture, avec une lèvre du col pour assurer la fermeture de ce dernier et comporte un embout tubulaire axial engageable sur l'appendice et apte à coopérer avec le col par des moyens de vissage
  • et des moyens sont prévus pour lier angulairement l'embout et l'appendice dans le sens de dévissage après un premier montage du capuchon sur le col.
To achieve the above objectives, the object of the invention is characterized in that
  • the neck is closed internally by a cover linked to said neck by a zone of least resistance,
  • a cylindrical appendage rises centrally from the cover inside the neck,
  • the cap is provided to cooperate, in the closed position, with a lip of the neck to ensure the closure of the latter and comprises an axial tubular end piece which can be engaged on the appendix and capable of cooperating with the neck by screwing means
  • and means are provided for angularly connecting the endpiece and the appendage in the unscrewing direction after a first assembly of the cap on the neck.

Diverses autres caractéristiques ressortent de la description faite ci-dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

La figure 1 est une perspective à l'état fermé du bouchon-verseur conforme à l'invention.Figure 1 is a perspective in the closed state of the pouring plug according to the invention.

La figure 2 est une coupe diamétrale prise selon le plan II - II de la figure 1.FIG. 2 is a diametral section taken along the plane II - II of FIG. 1 .

La figure 3 est une perspective éclatée, partie en coupe, mettant en évidence certaines caractéristiques constructives d'une variante de réalisation de l'objet de l'invention.Figure 3 is an exploded perspective, partly in section, highlighting certain constructive characteristics of an alternative embodiment of the object of the invention.

La figure 4 est une coupe-élévation partielle illustrant le bouchon-verseur selon l'invention dans l'état consécutif à la première ouverture.Figure 4 is a partial sectional elevation illustrating the pouring plug according to the invention in the state consecutive to the first opening.

La figure 5 est une coupe-élévation partielle faisant apparaître une variante de réalisation de l'un des moyens de l'invention.Figure 5 is a partial sectional elevation showing an alternative embodiment of one of the means of the invention.

Selon les figures 1 et 2, le bouchon-verseur conforme à l'invention est présenté en tant qu'élément indépendant susceptible d'être rapporté par une base de liaison 1 sur un récipient 2 en toute matière appropriée.According to Figures 1 and 2 , the pourer according to the invention is presented as an independent element capable of being attached by a connecting base 1 to a container 2 of any suitable material.

Les moyens de liaison entre la base 1 et le récipient 2 ne font pas partie directement de l'invention et relèvent de la technique antérieure connue. Dans le même esprit, il doit aussi être considéré que l'objet de l'invention pourrait être mis en oeuvre sur un bouchon-verseur dont la base 1 ferait partie intégrante du récipient 2.The connecting means between the base 1 and the container 2 are not directly part of the invention and fall under the known prior art. In the same spirit, it should also be considered that the object of the invention could be implemented on a pouring plug, the base 1 of which would form an integral part of the container 2 .

Dans l'exemple préféré, tel qu'illustré selon les figures 1 et 2, la base de liaison 1 est constituée par une collerette qui est liée à un col tubulaire cylindrique 3 d'axe x-x' par un soufflet 4 déformable selon une amplitude telle qu'il permette de placer le col 3, soit dans une position invaginée à l'intérieur du récipient 2, soit après traction dans une position d'extension, tel qu'illustré par la figure 2 et correspondant à un état d'utilisation.In the preferred example, as illustrated according to FIGS. 1 and 2 , the connecting base 1 is constituted by a collar which is linked to a cylindrical tubular neck 3 of axis xx ′ by a bellows 4 deformable according to such amplitude that it allows the neck 3 to be placed , either in an invaginated position inside the container 2 , or after traction in an extended position, as illustrated in FIG. 2 and corresponding to a state of use.

De préférence, le bouchon est réalisé en une matière plastique appropriée, telle qu'en polyéthylène basse densité.Preferably, the stopper is made of a suitable plastic material, such as low density polyethylene.

Le col cylindrique tubulaire 3 est prolongé par une partie supérieure 5 de forme épanouie, formant un bec verseur annulaire se terminant par une lèvre 6 à caractère légèrement déformable. Le col cylindrique 3 comporte, par ailleurs, sur sa paroi périphérique intérieure au moins un filet hélicoïdal 7 apte à coopérer avec des moyens de vissage complémentaire 8 présentés par la paroi périphérique extérieure d'un embout tubulaire 9 formé axialement par la face inférieure 10 d'une capsule 11 de fermeture du bec verseur. La capsule 11 comporte, à sa périphérie ou organisée de façon sensiblement équivalente, un anneau de préhension et de traction 12 occupant à l'état de repos une position stable dans le plan de la capsule 11, tel que cela est illustré par les figures 1 et 2. La capsule 11 présente, par ailleurs, à partir de sa face inférieure 10, un rebord annulaire 13 délimitant un logement 14 à l'intérieur duquel s'emboîte la lèvre 6 pour assumer une fonction de fermeture dans la position de montage de la capsule 11 sur le col 3.The tubular cylindrical neck 3 is extended by an upper part 5 of open shape, forming an annular pouring spout ending in a lip 6 of slightly deformable nature. The cylindrical neck 3 also comprises, on its inner peripheral wall at least one helical thread 7 capable of cooperating with complementary screwing means 8 presented by the outer peripheral wall of a tubular end piece 9 formed axially by the lower face 10 d 'A capsule 11 for closing the pouring spout. The capsule 11 comprises, at its periphery or organized in a substantially equivalent manner, a grip and traction ring 12 occupying, in the rest state, a stable position in the plane of the capsule 11 , as illustrated by FIGS. 1 and 2 . The capsule 11 has, moreover, from its lower face 10 , an annular rim 13 delimiting a housing 14 inside which the lip 6 fits to assume a closing function in the mounting position of the capsule 11 on collar 3 .

Selon l'invention, le col 3 est obturé sensiblement dans le plan de raccordement avec le soufflet 4, par un opercule 15 venu de moulage et présentant une zone 16 de moindre résistance qui peut être réalisée de toutes façons convenables. La zone 16 peut correspondre à un sillon périphérique dont le diamètre est, par exemple, voisin ou légèrement inférieur au diamètre intérieur du filet hélicoïdal 7. L'opercule 15 est surmonté par un appendice 17 cylindrique, s'élevant sensiblement sur toute la hauteur du col 3 et de la partie supérieure 5, en étant centré sur l'axe x-x'. De préférence mais non nécessairement, l'appendice 17 est réalisé sous une forme tubulaire, en présentant un diamètre extérieur choisi pour permettre son engagement à l'intérieur de l'embout tubulaire 9.According to the invention, the neck 3 is closed substantially in the connection plane with the bellows 4 , by a cover 15 molded and having an area 16 of lower resistance which can be achieved in any suitable manner. Zone 16 may correspond to a peripheral groove whose diameter is, for example, close to or slightly less than the inside diameter of the helical thread 7 . The cover 15 is surmounted by a cylindrical appendage 17 , rising substantially over the entire height of the neck 3 and the upper part 5 , while being centered on the axis x-x '. Preferably but not necessarily, the appendix 17 is produced in a tubular form, having an outside diameter chosen to allow its engagement inside the tubular end piece 9 .

La réalisation ci-dessus permet, lors du montage de la capsule 11, d'engager l'embout 9 sur l'appendice 17, comme cela est illustré par la figure 2.The above embodiment allows, during assembly of the capsule 11 , to engage the end piece 9 on the appendage 17 , as illustrated in FIG. 2 .

Selon l'invention, il est prévu de faire intervenir, entre l'appendice 17 et l'embout 9, des moyens capables de les lier angulairement dans le sens de dévissage après un premier montage de la capsule 11 sur le col 3, par la coopération des filets 7 et 8. Les moyens de liaison angulaire, désignés dans leur ensemble par la référence 18, sont constitués, dans un premier exemple de réalisation selon les figures 2 et 3, par des crans 18 en forme de dents de loup asymétriques, formées en saillie sur la partie supérieure de l'appendice 17 et plus particulièrement sur le rebord transversal de ce dernier. Chaque cran 18 comprend une rampe 19 inclinée de façon montante dans le sens de vissage normal et se raccordant à une face abrupte 20 qui aboutit à la rampe 19 du cran consécutif.According to the invention, provision is made to involve, between the appendix 17 and the endpiece 9 , means capable of angularly binding them in the unscrewing direction after a first assembly of the capsule 11 on the neck 3 , by the cooperation of nets 7 and 8 . The angular connection means, designated as a whole by the reference 18 , are constituted, in a first embodiment according to FIGS. 2 and 3 , by notches 18 in the form of asymmetrical wolf teeth, formed projecting from the upper part of Appendix 17 and more particularly on the transverse rim of the latter. Each notch 18 comprises a ramp 19 inclined upward in the normal screwing direction and connecting to an abrupt face 20 which terminates in the ramp 19 of the consecutive notch.

Les moyens de liaison angulaire comprennent, par ailleurs, sur le fond 21 de l'embout tubulaire 9, des crans complémentaires 22 présentant une forme conjuguée à celle des crans 18. Ainsi, lors de la première mise en place de la capsule 11, le vissage de l'embout 9 par les moyens 7 et 8 aboutit à faire coopérer les crans 18 et 22, jusque dans la position d'engagement axial maximal dans laquelle les crans 18 et 22 sont en engagement mutuel, s'opposant à toute possibilité de dévissage de la capsule 11.The angular connection means also comprise, on the bottom 21 of the tubular endpiece 9 , complementary notches 22 having a shape conjugated to that of the notches 18 . Thus, during the first positioning of the capsule 11 , the screwing of the end piece 9 by the means 7 and 8 results in the notches 18 and 22 cooperating, even in the position of maximum axial engagement in which the notches 18 and 22 are in mutual engagement, opposing any possibility of unscrewing the capsule 11 .

Les moyens de liaison angulaire, tels que décrits ci-dessus, pourraient être réalisés de façon sensiblement différente, en faisant intervenir des crans équivalents techniquement pour la fonction devant être assumée, mais formés relativement sur la périphérie extérieure de l'appendice 17 et respectivement sur la périphérie intérieure de l'embout 9, soit à proximité du bord transversal et du fond 21, soit à proximité de l'opercule 15.The angular connection means, as described above, could be produced in a substantially different way, by making use of technically equivalent notches for the function to be assumed, but formed relatively on the outer periphery of the appendage 17 and respectively on the inner periphery of the nozzle 9 , either near the transverse edge and the bottom 21 , or close to the cover 15 .

Selon l'invention, il est prévu de faire intervenir également des moyens 23 de liaison axiale, entre l'appendice 17 et l'embout 9. Dans une forme de réalisation avantageuse, les moyens 23 comprennent au moins un filet hélicoïdal 24 formé par la périphérie extérieure de l'embout 17 et au moins un filet hélicoïdal 25 présenté par la paroi périphérique interne de l'embout 9. Les filets 24 et 25 sont formés de manière à permettre un vissage entre eux simultané à celui des filets 7 et 8 décrits précédemment.According to the invention, provision is also made to involve means 23 for axial connection, between the appendix 17 and the endpiece 9 . In an advantageous embodiment, the means 23 comprise at least one helical thread 24 formed by the external periphery of the end piece 17 and at least one helical thread 25 presented by the internal peripheral wall of the end piece 9 . The threads 24 and 25 are formed so as to allow them to be screwed together simultaneously with that of the threads 7 and 8 described above.

Les filets 24 et 25 sont, par ailleurs, réalisés de manière à respecter la condition précédente qui est d'assurer la coopération et l'imbrication ou l'emboîtement des crans 18 et 22 lors du vissage à fond de filets de la capsule 11, par l'intermédiaire de l'embout 9, à la fois par engagement sur l'appendice 17 et par coopération avec le filet 7 du col 3.The threads 24 and 25 are, moreover, made so as to comply with the previous condition which is to ensure cooperation and the nesting or nesting of the notches 18 and 22 when screwing the threads of the capsule 11 to the bottom, by means of the end-piece 9 , both by engagement on the appendix 17 and by cooperation with the thread 7 of the neck 3 .

Ainsi, dans cette position, tel qu'illustré par la figure 2, la capsule 11 est montée de manière ferme et étanche sur le col 3 qui est, par ailleurs, obturé par l'intermédiaire de l'opercule 15. Cet état correspond à une première fermeture du récipient 2 après remplissage de son contenu.Thus, in this position, as illustrated in FIG. 2 , the capsule 11 is mounted in a firm and tight manner on the neck 3 which is, moreover, closed by means of the cover 15 . This state corresponds to a first closure of the container 2 after filling of its content.

Lorsque l'utilisateur souhaite opérer une première ouverture du récipient 2, il agit tout d'abord sur le ou les anneaux 12 pour placer le soufflet 4 dans la position selon la figure 2, à partir d'une position rentrée non représentée, mais bien connue.When the user wishes to operate a first opening of the container 2 , he first acts on the ring or rings 12 to place the bellows 4 in the position according to FIG. 2 , from a retracted position not shown, but indeed known.

Dans cet état, l'utilisateur peut alors agir sur la capsule 11 dans le sens classique de dévissage, pour extraire l'embout 9. Une telle action de dévissage qui est autorisée par la coopération des filets 7 et 8 se trouve, par contre, entravée par l'imbrication des crans 18 et 22.In this state, the user can then act on the capsule 11 in the conventional direction of unscrewing, to extract the end piece 9 . On the other hand, such an unscrewing action which is authorized by the cooperation of the threads 7 and 8 is hampered by the nesting of the notches 18 and 22 .

L'action de dévissage imposée par l'utilisateur se traduit donc par une tendance à l'entraînement en rotation dans le même sens de l'appendice 17, avec pour conséquence une rupture de la zone de moindre résistance 16.The unscrewing action imposed by the user therefore results in a tendency to drive in rotation in the same direction of appendix 17 , with the consequence of a rupture of the zone of least resistance 16 .

Simultanément, l'action de dévissage portée sur la capsule 11 fait coopérer les filets 7 et 8 qui génèrent un déplacement de l'embout 9 dans le sens axial selon la flèche f₁. En raison de la rotation relative entravée, entre l'embout 9 et l'appendice 17, le déplacement même minime de l'embout 9 dans le sens de la flèche f₁ contribue, en combinaison avec l'action précédente, à provoquer la rupture de l'opercule 15 le long de la zone de moindre résistance 16.Simultaneously, the unscrewing action carried on the capsule 11 causes the threads 7 and 8 to cooperate, which generate a displacement of the endpiece 9 in the axial direction along the arrow f₁ . Due to the relative rotation hampered, between the tip 9 and the appendage 17 , the movement even minimal of the tip 9 in the direction of the arrow f₁ contributes, in combination with the previous action, to causing the rupture of the cover 15 along the zone of least resistance 16 .

Ainsi et sans qu'une autre action soit à conduire par l'utilisateur, la première tentative de dévissage et d'ouverture du bouchon-verseur selon l'invention provoque la rupture de l'opercule 15 qui reste associé à l'appendice 17 lui-même lié par les moyens 23 à l'embout 9.Thus and without any other action being carried out by the user, the first attempt to unscrew and open the pouring plug according to the invention causes the rupture of the cover 15 which remains associated with the appendage 17 itself. - even linked by the means 23 to the nozzle 9 .

L'utilisateur est renseigné lors d'une première ouverture sur le caractère d'inviolabilité, en raison de la perception tactile qu'il percoit nécessairement par l'exigence d'un effort de rotation supérieure à la normale pour provoquer, par les deux actions ci-dessus, la rupture de la zone 16.The user is informed during a first opening on the character of inviolability, because of the tactile perception that he necessarily perceives by the requirement of a rotational force greater than normal to cause, by the two actions above, the rupture of zone 16 .

La capsule 11 peut ensuite être dévissée pour ouvrir totalement le col 3, comme illustré par la figure 4 et permettre le vidage partiel du récipient 2.The capsule 11 can then be unscrewed to fully open the neck 3 , as illustrated in FIG. 4 and allow the partial emptying of the container 2 .

Lors de la fermeture ultérieure, le vissage de l'embout 9 s'effectue par coopération du filet 8 avec le filet 7, jusqu'à amener la lèvre 6 à l'intérieur du logement 14 en coopération avec le rebord 13 et la face interne 10, pour assurer la fermeture étanche du col 3 à l'intérieur duquel l'opercule 15 a été replacé.During the subsequent closure, the end piece 9 is screwed by cooperation of the thread 8 with the thread 7 , until the lip 6 is brought inside the housing 14 in cooperation with the flange 13 and the internal face. 10 , to ensure the tight closure of the neck 3 inside which the cover 15 has been replaced.

Les moyens, selon l'invention, permettent de réaliser en une seule opération de moulage en une même matière, d'une part, le col 3 et d'autre part, la capsule 11 qui peuvent être montés, comme dit précédemment, pour assurer une fermeture étanche avec témoignage d'inviolabilité perçu par l'utilisateur lors de la première ouverture.The means according to the invention make it possible to carry out, in a single molding operation in the same material, on the one hand, the neck 3 and on the other hand, the capsule 11 which can be mounted, as said previously, to ensure a watertight closure with evidence of inviolability perceived by the user during the first opening.

L'effort supplémentaire de dévissage nécessité pour la rupture de la zone 16 n'implique pas, pour l'utilisateur, une dépense physique, importante, étant donné qu'il se développe à partir d'une capsule 11 de grand diamètre et que l'entraînement en rotation est transformé par les moyens 18 et les moyens 23, en une double action de déformation tournante dans le plan et de déplacement axial qui, en combinaison, provoquent la déchirure de la zone 16 qui peut être réalisée avec une épaisseur telle qu'elle garantit dans tous les cas l'existence d'une barrière étanche entre le milieu ambiant et le volume interne du récipient 2.The additional unscrewing effort required for the rupture of the zone 16 does not involve, for the user, a significant physical expense, since it develops from a capsule 11 of large diameter and that the the rotational drive is transformed by the means 18 and the means 23 , into a double action of deformation rotating in the plane and of axial displacement which, in combination, causes the region 16 to be torn which can be produced with a thickness such that 'It guarantees in all cases the existence of a tight barrier between the ambient medium and the internal volume of the container 2 .

La figure 5 montre une variante de réalisation dans laquelle les moyens 23 de liaison axiale entre l'appendice 17 et l'embout 9 sont constitués par, au moins, une nervure 26 continue ou discontinue, à section droite transversale asymétrique, formée en saillie par exemple par la face périphérique extérieure de l'appendice 17, pour coopérer avec une conformation complémentaire ou gorge 27 présentée par exemple par la face périphérique intérieure de l'embout 9.FIG. 5 shows an alternative embodiment in which the means 23 for axial connection between the appendix 17 and the endpiece 9 are constituted by, at least, a rib 26 continuous or discontinuous, with asymmetrical cross section, projecting for example from the outer peripheral face of the appendage 17 , to cooperate with a complementary conformation or groove 27 presented for example by the inner peripheral face of the end piece 9 .

La conformation en section droite transversale de la nervure 26 et de la conformation 27, est choisie pour qu'après emboîtement relatif lors du premier montage de la capsule 11 sur le col 3, une liaison axiale soit établie pour s'opposer au déplacement relatif dans le sens de la flèche f₁ de l'embout 9, par rapport à l'appendice 17.The conformation in cross section of the rib 26 and of the conformation 27 is chosen so that after relative fitting during the first mounting of the capsule 11 on the neck 3 , an axial connection is established to oppose the relative displacement in the direction of the arrow f₁ of the end piece 9 , relative to appendix 17 .

Bien que cela ne soit pas représenté, il doit être considéré que la nervure continue ou discontinue 26 pourrait être aussi indifféremment formée en saillie par la paroi périphérique intérieure de l'embout 9.Although this is not shown, it should be considered that the continuous or discontinuous rib 26 could also be equally projecting from the inner peripheral wall of the end piece 9 .

L'emplacement relatif de la nervure 26 et de la conformation 27 peut être choisi de différentes façons sur toute la hauteur utile de l'appendice 17, en fonction des conditions de fabrication retenues.The relative location of the rib 26 and the conformation 27 can be chosen in different ways over the entire useful height of the appendage 17 , depending on the manufacturing conditions adopted.

L'invention n'est pas limitée aux exemples décrits et représentés car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown since various modifications can be made thereto without departing from its scope.
