Description

La présente invention concerne des moyens de bouchage inviolables d'un récipient du type comportant une capsule constituée par une jupe ou manchon cylindrique, pourvue d'une ouverture centrale, assurant le verrouillage d'un obturateur de l'orifice du récipient, et sur laquelle est fixé par collage ou soudage un opercule déchirable en feuille d'aluminium ou similaire, l'opercule étant dimensionné de manière à déborder par rapport à la capsule à laquelle il est fixé et sa partie débordante, c'est-à-dire toute sa périphérie, étant rendue solidaire par collage, scellage ou autres, d'une bague rigide de préhension engagée, au moins partiellement, sur la capsule.The present invention relates to tamper-evident closure means for a container of the type comprising a capsule constituted by a cylindrical skirt or sleeve, provided with a central opening, ensuring the locking of a shutter of the orifice of the container, and on which is fixed by gluing or welding a tear-off cover made of aluminum foil or the like, the cover being dimensioned so as to project beyond the capsule to which it is fixed and its projecting part, that is to say all of its periphery, being made integral by bonding, sealing or other, of a rigid gripping ring engaged, at least partially, on the capsule.

De tels moyens sont décrits dans le brevet français 2 529 531 déposé au nom de la Demanderesse. Ce type de bouchage peut être utilisé sur certains récipients contenant des produits pharmaceutiques liquides stériles à injecter. L'obturateur est un bouchon étanche en matière souple enfoncé dans l'orifice du col du récipient et apte à être traversé par l'aiguille d'une seringue pour le prélèvement du produit. La capsule verrouillant cet obturateur est pourvue d'un cran engagé élastiquement sous un épaulement du col du récipient et d'une ouverture centrale permettant le passage de l'aiguille et est fermée, avant usage, par un opercule déchirable qui lui est fixé par collage thermoscellage ou autres et qui permet d'isoler totalement le bouchon obturateur vis-à-vis des impuretés extérieures et de garantir ainsi la stabilité du produit contenu dans le récipient. Cet opercule est également fixe à une bague rigide de préhension reliée à la capsule par des ponts de matières et permettant l'arrachage sûr, facile et praticable d'une seule main, de l'opercule afin de donner accès à l'obturateur par l'ouverture centrale de la capsule.Such means are described in French patent 2,529,531 filed in the name of the Applicant. This type of closure can be used on certain containers containing sterile liquid pharmaceutical products for injection. The obturator is a tight plug made of flexible material inserted into the orifice of the neck of the container and capable of being crossed by the needle of a syringe for withdrawing the product. The capsule locking this obturator is provided with a notch engaged elastically under a shoulder of the neck of the container and with a central opening allowing the passage of the needle and is closed, before use, by a tear-off seal which is fixed to it by bonding. heat-sealing or others and which makes it possible to completely isolate the plug vis-à-vis external impurities and thus guarantee the stability of the product contained in the container. This cover is also fixed to a rigid gripping ring connected to the capsule by bridges of materials and allowing the safe, easy and practicable tearing off of the cover in order to give access to the shutter by the central opening of the capsule.

Cette réalisation, si elle convient tout à fait aux injectables, n'est pas adaptée aux autres produits pharmaceutiques stériles, par exemple pulvérulents, pour lesquels il est nécessaire d'ôter complètement la capsule de verrouillage afin de pouvoir enlever l'obturateur et avoir accès au produit contenu.This embodiment, if it is entirely suitable for injectables, is not suitable for other sterile pharmaceutical products, for example pulverulent, for which it is necessary to completely remove the locking capsule in order to be able to remove the obturator and have access to the product contained.

Le but de la présente invention est donc de fournir des moyens de bouchage assurant une étanchéité parfaite tout en permettant un déchirage sûr et facile de la capsule de verrouillage, qui devra pouvoir être effectué rapidement et pratiquement d'une seule main et donner systématiquement un résultat satisfaisant.The object of the present invention is therefore to provide sealing means ensuring perfect sealing while allowing safe and easy tearing of the locking capsule, which must be able to be carried out quickly and practically with one hand and systematically give a result. satisfactory.

Ces buts sont atteints par la présente invention du fait que dans les moyens de bouchage inviolables d'un récipient qu'elle concerne et qui sont du type précité, la bague rigide de préhension est reliée par un pont de matière à une partie de l'extrémité supérieure de la jupe cylindrique de la capsule, au voisinage d'au moins une ligne de déchirage s'étendant sur toute la hauteur de la jupe cylindrique et étant associée a une découpe partielle ménagée sur la paroi d'extrémité de la capsule et s'étendant de la ligne de déchirage considérée jusqu'à l'ouverture centrale de la capsule, de sorte que cette jupe se déchire suivant la ligne de déchirage lors de l'arrachage de l'opercule déchirable à l'aide de la bague rigide de préhension.These objects are achieved by the present invention because in the tamper-evident closure means of a container which it relates to and which are of the aforementioned type, the rigid gripping ring is connected by a bridge of material to a part of the upper end of the cylindrical skirt of the capsule, in the vicinity at least one tear line extending over the entire height of the cylindrical skirt and being associated with a partial cut formed on the end wall of the capsule and extending from the tear line considered up to l 'central opening of the capsule, so that this skirt is torn along the tear line when the tear-off seal is torn off using the rigid gripping ring.

Cette manipulation aisée de la bague conduit simultanément à l'arrachage de l'opercule et à la déchirure de la capsule sur toute la hauteur de sa jupe. Il suffit donc de la retirer pour avoir accès à l'obturateur.This easy manipulation of the ring leads simultaneously to tearing off the cover and tearing of the capsule over the entire height of its skirt. So just remove it to access the shutter.

Dans ces moyens de bouchage, l'opercule présente l'avantage de protéger la partie visible du bouchon en caoutchouc contre toute pollution, qu'elle soit liquide ou sous forme de poussière. Cet opercule présente aussi l'avantage supplémentaire de pouvoir servir de support à toute information concernant le produit conditionné dans le récipient telle que, notamment, son identification ou toute autre précision.In these sealing means, the cover has the advantage of protecting the visible part of the rubber stopper against any pollution, whether it is liquid or in the form of dust. This cover also has the additional advantage of being able to serve as a support for any information concerning the product packaged in the container such as, in particular, its identification or any other precision.

Suivant une forme préférée de réalisation de l'invention, le pont de matière reliant la bague rigide de préhension a la jupe cylindrique est délimité circonférentiellement par les deux extrémités supérieures de deux lignes de déchirage parallèles aux génératrices de la jupe cylindrique.According to a preferred embodiment of the invention, the material bridge connecting the rigid gripping ring to the cylindrical skirt is delimited circumferentially by the two upper ends of two tear lines parallel to the generatrices of the cylindrical skirt.

De préférence, le pont de matière est prolongé jusqu'à l'ouverture centrale de la capsule par une languette définie par deux découpes partielles ménagées sur la paroi d'extrémité de la capsule dont chacune est comprise dans le plan diamétral d'une ligne de déchirage.Preferably, the material bridge is extended to the central opening of the capsule by a tongue defined by two partial cutouts formed on the end wall of the capsule, each of which lies in the diametral plane of a line of scrapping.

Conformément a une disposition intéressante de l'invention, la bague rigide de préhension est équipée, dans la région sensiblement diamétralement opposée au pont de matière, d'un bec s'étendant vers l'extérieur apte à faciliter la manipulation de ladite bague.In accordance with an advantageous arrangement of the invention, the rigid gripping ring is equipped, in the region substantially diametrically opposite the bridge of material, with a spout extending outwards capable of facilitating the handling of said ring.

Afin d'éviter tout arrachage accidentel de la bague de préhension, elle est liée à la capsule par au moins un bras de matière, de préférence deux, conçus comme des amorces de rupture faciles à briser, ces bras de matières étant avantageusement disposés au niveau du bec de la bague de préhension.In order to avoid any accidental tearing off of the gripping ring, it is linked to the capsule by at least one arm of material, preferably two, designed as breaking initiators easy to break, these arms of material being advantageously arranged at the level of the grip ring spout.

Pour renforcer le caractère inviolable de ces moyens de bouchage, la capsule est réalisée en un matériau thermoplastique tel que le polypropylène apte à se fendre dès lors que l'on essaye de procéder à l'ouverture du récipient par un autre moyen que la bague de préhension.To reinforce the tamper-evident nature of these sealing means, the capsule is made of a thermoplastic material such as polypropylene able to split as soon as an attempt is made to open the container by means other than the grip ring.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif, une forme d'exécution de ces moyens de bouchage dans le cas de leur application à la fermeture d'un récipient contenant un produit pharmaceutique stérile :

  • Figure 1 en est une vue éclatée en perspective,
  • Figure 2 en est une vue en coupe suivant la ligne II-II de figure 1,
  • Figure 3 en est une vue en coupe suivant la ligne III-III de figure 2, le col du récipient et l'obturateur n'étant pas représentés ;
  • Figure 4 en est une vue en perspective éclatée montrant la bague rigide sans l'opercule déchirable et la jupe cylindrique de la capsule après son déchirage.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, representing by way of nonlimiting example, an embodiment of these plugging means in the case of their application to the closure of a container containing a sterile pharmaceutical product:
  • Figure 1 is an exploded perspective view,
  • Figure 2 is a sectional view along the line II-II of Figure 1,
  • Figure 3 is a sectional view along line III-III of Figure 2, the container neck and the shutter not being shown;
  • Figure 4 is an exploded perspective view showing the rigid ring without the tearable cap and the cylindrical skirt of the capsule after tearing.

Le récipient de l'ensemble illustré sur le dessin est un flacon dont seul le col 2 est visible. Près de son extrémité supérieure qui entoure l'orifice 3 du flacon, le col 2 présente un épaulement externe 4 dont la présence est mise à profit pour assurer la fixation par engagement élastique d'une capsule 5 en matière thermoplastique, de préférence le polypropylène, ou similaire, qui assure elle-même le verrouillage d'un obturateur 6 en matière élastique naturelle ou synthétique ou autre.The container of the assembly illustrated in the drawing is a bottle of which only the neck 2 is visible. Near its upper end which surrounds the orifice 3 of the bottle, the neck 2 has an external shoulder 4 whose presence is used to ensure the fixing by elastic engagement of a capsule 5 made of thermoplastic material, preferably polypropylene, or the like, which itself ensures the locking of a shutter 6 made of natural or synthetic elastic material or the like.

La capsule 5 est constituée par un manchon ou jupe cylindrique 7 pourvu d'une ouverture centrale 8a ménagée dans sa paroi d'extrémité 8. The capsule 5 is constituted by a cylindrical sleeve or skirt 7 provided with a central opening 8a formed in its end wall 8.

Un opercule déchirable 9 en feuille d'aluminium recouvre l'ouverture centrale 8a du manchon ou jupe cylindrique 2 pour protéger l'obturateur 6 contre toute atteinte de poussières ou autres impuretés. Dans l'exemple illustré sur le dessin, et comme il ressort en particulier de la figure 2, l'opercule déchirable 9 est fixé par thermoscellage à la paroi d'extrémité 8 du manchon 7, tandis que la partie débordante 9a par rapport à la jupe cylindrique 7 est assemblée de la même façon a une bague rigide de préhension 10 engagée sur la capsule 5. A tearable lid 9 made of aluminum foil covers the central opening 8a of the sleeve or cylindrical skirt 2 to protect the shutter 6 against any attack by dust or other impurities. In the example illustrated in the drawing, and as is apparent in particular from FIG. 2, the tearable lid 9 is fixed by heat sealing to the end wall 8 of the sleeve 7, while the projecting part 9a relative to the cylindrical skirt 7 is assembled in the same way to a rigid gripping ring 10 engaged on the capsule 5.

Cette bague rigide de préhension 10 est reliée par un pont de matière 11 à une partie de l'extrémité supérieure de la jupe cylindrique 7 délimitée circonférentiellement par les deux extrémités supérieures de deux lignes de déchirage 12 parallèles aux génératrices de la jupe cylindrique 7 et s'étendant sur toute la hauteur de cette dernière. Il s'agit, en fait, de deux gorges 12 suivant lesquelles la jupe cylindrique 7 comporte une moindre épaisseur de matière et est fragilisée. La traction exercée par l'intermédiaire du pont de matière 11 à l'aide de la bague rigide de préhension 10 suffit ainsi au déchirage de la capsule suivant ces deux lignes 12. This rigid gripping ring 10 is connected by a material bridge 11 to a part of the upper end of the cylindrical skirt 7 delimited circumferentially by the two upper ends of two tear lines 12 parallel to the generatrices of the cylindrical skirt 7 and s extending over the entire height of the latter. It is, in fact, two grooves 12 along which the cylindrical skirt 7 has a lesser material thickness and is weakened. The traction exerted via the material bridge 11 using the rigid gripping ring 10 is thus sufficient to tear the capsule along these two lines 12.

Le pont de matière 11 est prolongé jusqu'à l'ouverture centrale 8a de la capsule 5 par une languette 13 définie par deux découpes partielles 14 ménagées dans la paroi d'extrémité 8 de la capsule 5. Chaque découpe 14 est comprise dans le plan diamétral d'une ligne de déchirage 12. The material bridge 11 is extended to the central opening 8a of the capsule 5 by a tongue 13 defined by two partial cutouts 14 formed in the end wall 8 of the capsule 5. Each cutout 14 is included in the plane diametral of a tear line 12.

Dans la région de la capsule 5 diamétralement opposée à la languette 13, la bague rigide de préhension 10 est reliée à la paroi d'extrémité 8 par l'intermédiaire de deux bras de matière conçus comme des amorces de rupture faciles à briser. Au niveau de ces bras 15, la bague rigide de préhension 10 présente un bec 16 saillant vers l'extérieur et prévu pour faciliter sa manipulation.In the region of the capsule 5 diametrically opposite to the tongue 13, the rigid gripping ring 10 is connected to the end wall 8 by means of two arms of material designed as fracture primers easy to break. At the level of these arms 15, the rigid gripping ring 10 has a spout 16 projecting outwards and intended to facilitate its handling.

Le déchirage de la capsule 5 s'opère comme suit :The tearing of the capsule 5 takes place as follows:

L'utilisateur applique l'extrémité de son pouce en-dessous du bec 16 et exerce une poussée du bas vers le haut de manière à briser les deux amorces de rupture 15. Il ne reste plus qu'à tirer sur la bague 10 pour arracher l'opercule déchirable 9 de la paroi d'extrémité 8 et déchirer la partie de la jupe cylindrique 7 comprise entre ses deux lignes de déchirage 12. La bague 10 se trouve ainsi totalement désolidarisée de la capsule 5 qu'il est alors aisé d'enlever du col 2 du récipient en jouant sur son élasticité. La figure 4 illustre parfaitement cette situation.The user applies the end of his thumb below the spout 16 and exerts a push from the bottom upwards so as to break the two starting points 15. All that remains is to pull on the ring 10 to tear off the tearable lid 9 of the end wall 8 and tear the part of the cylindrical skirt 7 between its two tear lines 12. The ring 10 is thus completely detached from the capsule 5 that it is then easy to remove from the neck 2 of the container by playing on its elasticity. Figure 4 illustrates this situation perfectly.

L'obturateur 6 n'étant plus verrouillé par la capsule 5, il suffit à l'utilisateur de l'ôter pour avoir accès au produit stérile et conservé comme tel contenu dans le récipient.The shutter 6 is no longer locked by the capsule 5, it suffices for the user to remove it to gain access to the sterile product and stored as such contained in the container.

Il est clair que les moyens de bouchage inviolables conformes à l'invention permettent à la fois un arrachage de l'opercule 9 et un déchirage de la capsule 5 aisés, tout en assurant l'étanchéité parfaite du récipient.It is clear that the tamper-evident closure means in accordance with the invention allow both easy removal of the cover 9 and easy tearing of the capsule 5 , while ensuring perfect sealing of the container.

Afin de diminuer la durée d'encapsulage des récipients à l'aide de ces moyens de bouchage, la capsule est équipée de butées 17 de positionnement de l'obturateur 6 de l'orifice du col 2 du récipient. Comme le montre notamment la figure 2, ces butées 17 sont réparties uniformément sur l'extrémité supérieure de la paroi intérieure de la jupe cylindrique 7. Elles permettent de bloquer l'obturateur élastique 6 par rapport à la capsule et d'engager, ainsi, simultanément ces deux éléments sur le col 2 du récipient au moment de son bouchage.In order to reduce the duration of encapsulation of the containers using these capping means, the capsule is equipped with stops 17 for positioning the shutter 6 of the orifice of the neck 2 of the container. As shown in particular in FIG. 2, these stops 17 are distributed uniformly over the upper end of the inner wall of the cylindrical skirt 7. They make it possible to block the elastic shutter 6 relative to the capsule and thus to engage, simultaneously these two elements on the neck 2 of the container when it is capped.

Comme il va de soi et comme il ressort de ce qui précède, l'invention ne se limite pas à la seule forme d'exécution de ces moyens de bouchage, qui a été décrite ci-dessus à titre d'exemple non limitatif elle en embrasse, au contraire, toutes les variantes.As is obvious and as is clear from the above, the invention is not limited to the sole embodiment of these plugging means, which has been described above by way of nonlimiting example, it embraces, on the contrary, all variants.

C'est ainsi que, par exemple, la jupe cylindrique 7 pourrait ne comporter qu'une seule ligne de déchirage 12 associée a une découpe partielle 14 de la paroi d'extrémité 8, ou bien que la bague 10 pourrait ne pas être liée par une ou plusieurs amorces de rupture 15 à la capsule 5, ou bien encore que celle-ci ne comporte pas de butées de positionnement de l'obturateur 6. Thus, for example, the cylindrical skirt 7 could have only one tear line 12 associated with a partial cut 14 of the end wall 8, or else the ring 10 could not be linked by one or more initiations of rupture 15 at the capsule 5, or even that the latter does not comprise stops for positioning the shutter 6.

2. Closure means according to Claim 1, characterised in that the bridge of material (11) connecting the rigid ring grip (10) to the cylindrical skirt (7) is defined circumferentially by the two upper ends of two tearing lines (12) parallel to the generating lines of the cylindrical skirt (7).
3. Closure means according to Claim 2, characterised in that the bridge of material (11) is extended as far as the central opening (8a) of the capsule (5) by a tongue (13) defined by two partial cut-outs (14) provided on the end wall (8) of the capsule (5), each said cut-out being comprised in the diametral plane of a tearing line (12).
4. Closure means according to any one of Claims 1 to 3, characterised in that the rigid ring grip (10) is equipped, in the region substantially diametrally opposite the bridge of material (11), with a tab (16) extending towards the exterior, and adapted to facilitate manipulation of the said ring (10).
5. Closure means according to any one of Claims 1 to 4, characterised in that the ring grip (10) is connected to the capsule (5) by at least one fracture start point (15) which is easy to break.
6. Closure means according to Claim 5, characterised in that the fracture start points (15) are two in number, and connect the tab (16) of the ring grip (10) to the capsule (5).
7. Closure means according to any one of Claims 1 to 6, characterised in that there are provided positioning stops (17) for the seal (6) of the mouth (3) of the container (2), disposed on the inner wall of the cylindrical skirt (7), enabling the seal (6) to be fixed to the capsule (5), and enabling these two elements to be engaged together on the neck (2) of the container when it is closed.
8. Closure means according to any one of Claims 1 to 7, characterised in that the capsule is made of a thermoplastic material such as polypropylene which tends to split when any attempt is made to open the container by a means other than the ring grip.
