Definitions

  • the present invention relates to a cap for a container with a neck, intended to block a stopper in the neck of said container.
  • the invention relates in particular to a locking cap suitable for vials, for example for a pharmaceutical product, requiring the total removal of the stopper and the cap for the extraction or reconstitution of the product.
  • EP2814752 which offers a cap locking device on a container with a neck, completely removable.
  • This device comprises an outer ring shaped to cover the stopper and surround the upper flange of the neck of the container. It also comprises an internal ring in the form of a ring, suitable for being housed in the external ring and provided with lower internal notches intended to bear under said flange in order to be fixed on the container.
  • the inner ring also includes outer notches allowing it to be secured in the outer ring.
  • Such a cap makes it possible to block a stopper in the neck of the container, said stopper being held in the internal ring.
  • locking devices are commonly used to store pharmaceuticals in vials. Some products are taken using a syringe, inserted through the elastomer stopper, after removing a protective cap from the upper part of the locking device. Other products require the full opening of the bottle to be extracted or to be reconstituted.
  • the aforementioned document provides a frangible zone, at the level of the outer ring of the locking device, capable of being broken in order to allow the opening of said ring and its withdrawal with respect to the collar of the container.
  • the internal ring is for its part provided with a deformable and breakable bridge, capable of being broken to allow the removal of said ring relative to the flange, allowing access to the stopper and its removal from the neck of the container.
  • a drawback of this solution comes from the lack of repeatability of the opening between two devices, in particular from the breaking of the breakable deformable bridge, because it is difficult to pull repeatedly on the inner ring until the bridge breaks.
  • Another drawback of this solution comes from the lack of repeatability of the assembly between the inner and outer rings, which assembly must ensure the tightness of the closure.
  • the document EP2464577 presents a device for locking a stopper in the neck of a container which is reliable and repeatable in terms of closure sealing but does not allow the complete removal of said device to extract the stopper.
  • This device comprises the characteristics of the preamble of claim 1.
  • the document US5269429 provides a closure cap comprising a breaking point, so as to allow removal of said cap.
  • the present invention proposes an alternative solution to known solutions and aimed at remedying all or part of the drawbacks of the state of the art.
  • a locking cap reliably sealing the closure and allowing ergonomic and secure removal of the cap on the one hand, and on the other hand, repeatable on a plurality of caps, to extract the elastomeric stopper and access the contents of the container.
  • the present invention relates to a locking cap 100 for a container 200 with a neck, intended to block a stopper 10 in the neck 201 of said container 200.
  • the container 200 may in particular take the form of a bottle, having a neck 201 of. circular opening, terminating in a flange 202 flared with respect to the outer perimeter of the neck 201.
  • the outer diameter of the flange 202 is greater than the outer diameter of the neck 201, as illustrated in Figures la, lb.
  • the stopper 10 has a circular section and a T-shape with a head 11 and a foot 12, the head 11 having a diameter greater than the foot 12.
  • the foot 12 of the stopper 10 is completely inserted into the neck 201, the head 11 locks against the collar 202.
  • the stopper 10 when the contents of the bottle is intended to be lyophilized, the stopper 10 has an opening 13 in its base 12, to allow the passage of the evaporative flows as long as the stopper 10 is not completely inserted into the neck 202 ( figures 1b and 1d ).
  • the cap 100 when it is associated with the stopper 10, is capable of adopting two positions on the container 200: a first position, called the intermediate holding position, in which the stopper 10 is partially inserted into the neck 201 ( figures 1a, 1b ). It is in this position that the container 200 can be subjected to a freeze-drying step, because the partial depression of the stopper allows the evaporative flows to pass through the opening 13 made in the base 12 of the stopper 10.
  • a first position called the intermediate holding position
  • the stopper 10 is partially inserted into the neck 201 ( figures 1a, 1b ). It is in this position that the container 200 can be subjected to a freeze-drying step, because the partial depression of the stopper allows the evaporative flows to pass through the opening 13 made in the base 12 of the stopper 10.
  • the cap 100 associated with the stopper 10 can also adopt a second position, called a locking position, in which the stopper 10 is fully inserted, and locked in the neck 201 by the cap 100 ( figures 1c, 1d ). In this position, the stopper 10 hermetically closes the container 200, the foot 12 (and therefore the opening 13 when it is present) being completely surrounded by the neck 201 of the container 200.
  • the cover 100 comprises an outer body 30 and a cage 20 configured to fit together and lock axially in said outer body 30.
  • the cage 20 comprises an upper ring 21, a plurality n of branches 22 connected to the upper ring 21 and defining therewith a general cylindrical shape of the cage 20, of central axis z ( figures 2a, 2b ).
  • the cage 20 also includes n / 2 first bridges 25 and n / 2 second bridges 26, each connecting two neighboring branches 22 between them.
  • the first bridges 25 and the second bridges 26 are arranged alternately around the perimeter of the cage 20.
  • the cage has six branches 22, three first bridges 25 and three second bridges 26.
  • the first bridges 25 occupy between 20% and 40% of the perimeter of the cage 20, for example 30%; and the second bridges 26 occupy between 40% and 70% of said perimeter, for example 60%.
  • the residual perimeter to reach 100% is occupied by branches 22.
  • the cage 20 comprises a plurality of first tongues 23, each being supported by a first bridge 25.
  • Each first tongue 23 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, at an angle between 20 ° and 60 °, advantageously around 45 °, in the direction of the upper ring 21.
  • first tabs 23 are intended to block the stopper 10 inside the cage 20, against the upper ring 21, when the stopper 10 is associated with the cap 100.
  • the first tabs 23 flex to allow the head 11 of the device to pass through. stopper 10 when the latter is introduced into the cage 20, and come to be blocked under the head 11, to prevent the stopper 10 from coming out of said cage 20.
  • the cap 10 remains firmly attached to the cap 100 and no accidental separation between cap 10 and cap 100 can take place, in particular, when the cap 100 is in its intermediate holding position on the container. 200.
  • the cage 20 advantageously comprises a plurality of second tongues 24, each supported by a second bridge 26.
  • Each second tongue 24 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, with a angle between 20 ° and 60 °, advantageously around 30 °, in the direction of the upper ring 21.
  • These second tabs 24 are intended to remain above the collar 202, slightly raised or in contact thereon, when the cap 100 is in the intermediate holding position ( figure 1a ). In this intermediate holding position, the second bridges 26 and the branches 22 are intended to at least partially surround the collar 202. This configuration allows a more stable and secure mechanical holding of the plug 10 / cap 100 assembly, during potentials. lyophilization steps.
  • the second tabs 24 are intended to bear under the collar 202 of the neck 201 of the container 200, when the cap 100 is in the locking position ( figures 1c ). Indeed, during the passage in the locked position, the cap 10 / cap 100 assembly will descend into / around the neck 201 of the container 200, so as to completely depress the foot 12 of the stopper 10 in the neck 201, until that its head 11 rests on the collar 202. When driving in, the second tabs 24 flex and retract to allow the collar 202 to pass through, and come to be blocked under the latter, thus locking the stopper 10 on the container 200.
  • the first tabs 23 are erased because they are resting against the peripheral edge of the collar 202. They therefore do not remain under the head 11 of the plug 10 and let the latter rest on the collar 202.
  • the first bridges 25 then surround the peripheral edge of the collar 202.
  • the second tabs 24 are configured to allow a passage from the intermediate holding position to the locking position of the cover 100 associated with the stopper 10, when a low force between 30 N and 70 N, preferably between 30N and 50N , is applied on the cap 100.
  • the second tabs 24 have an inclination relative to the branches 22 of the order of 20 ° to 60 °, a thickness between 0.6 and 1.3mm and a flexibility conferred by the choice of the material forming the cage 20 .
  • This advantageous configuration thanks to which the passage into the locking position is made possible by applying a force of low amplitude, makes it possible to collectively lock a plurality of caps 100 on their respective containers 200, by means of a plate exerting a force. in the upper part of the plurality of caps 100.
  • This low closing force also makes it possible to compensate for the large variations in height of the containers 200 and thus to achieve closure of all of said containers present under the closing plate without generating any broken.
  • the locking cap 100 according to the present invention is completely removable and allows the removal of the stopper 10 for full opening of the container.
  • the cage 20 comprises at least one second bridge 26 supporting an opening tab 27 inclined towards the outside of the cage 20, in the direction of the upper ring 21.
  • the (at least one) second bridge 26 also has a zone breakable 28 adjacent to said opening tab 27 ( figures 2a, 2b ).
  • the outer body 30 also has a breakable part 35 ( figures 3a, 3b ).
  • the outer body 30 is in a generally cylindrical shape with a central axis z. One end 30a of the outer body 30 is closed and the other end 30b is open. The open end 30b is designed to accommodate the cage 20, which will fit into the outer body 30, placing the upper ring 21 against the inner surface of the closed end 30a.
  • the breakable part 35 may for example consist of a portion of the closed end 30a and of the cylindrical wall, said portion being delimited by a double groove at which the thickness of the outer body 30 is reduced ( figure 3b ).
  • the outer body 30 is configured to completely surround the cage 20 when the latter is fitted, so as to prevent any access to said cage 20 from the outside, when the cap 100 locks the stopper 10 on the container 200. In the position of locking the cover 100, the outer body 30 therefore prevents in particular access to the opening tab 27.
  • a capsule 32 is fixed to the outer surface of the closed end 30a of the outer body 30.
  • the capsule 32 may include a tenon intended to pass through an orifice (visible on the figure 3a ) present for example at the center of the closed end 30a of the outer body 30, and in particular in the portion of the end belonging to the breakable part 35.
  • the fixing between the cap 32 and the outer body 30 can be done by snap-fastening .
  • the opening tab 27 is initially designed so that it is inclined towards the outside of the cage 20, in the direction of the upper ring 21; due to its elastic properties, it is able to fold back parallel to the inner walls of the outer body 30, when the cage 20 is axially locked in the outer body 30.
  • the opening tab 27 is recovered.
  • the opening tab 27 advantageously has an elongated shape, which makes gripping all the more easier.
  • the gripping and the application of a tension force on the opening tab 27 causes the breakage at the level of the breakable zone 28 of the second bridge 26: the cage 20 can then be easily detached from the neck 201 of the container 200 leaving free access to removing the cap 10.
  • the opening tongue 27, by virtue of its shape, its inclination and its location relative to the breakable zone 28 formed on a second bridge 26, promotes reliable and repeatable rupture on a plurality of cages 20.
  • the outer body 30 comprises a circular groove 31, formed in its cylindrical inner walls and able to cooperate with complementary means of the cage 20, to axially lock the cage 20 in the outer body 30 ( figure 3b ).
  • These means are, for example, notches 221 arranged on the branches 22 of the cage 20 (visible on the figures 2a and 2b ) and designed to come to lock in the groove 31, when the cage 20 is completely inserted into the outer body 30.
  • the outer body 30 can thus rotate freely around the central axis z, when the cap 100 is in the locking position on the container 200, without damaging the cage 20 and risk affecting the reliability and tightness of closure of the container 200.
  • each first bridge 25 is designed to provide an open space 251 between it and the flange 202, when the cap 100 is in its intermediate holding position ( figure 2b ).

Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne une coiffe pour un récipient à col, destinée à bloquer un bouchon dans le col dudit récipient. L'invention concerne en particulier une coiffe de verrouillage adaptée à des flacons, par exemple pour produit pharmaceutique, nécessitant le retrait total du bouchon et de la coiffe pour l'extraction ou la reconstitution du produit.The present invention relates to a cap for a container with a neck, intended to block a stopper in the neck of said container. The invention relates in particular to a locking cap suitable for vials, for example for a pharmaceutical product, requiring the total removal of the stopper and the cap for the extraction or reconstitution of the product.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

On connaît le document EP2814752 qui propose un dispositif de verrouillage de bouchon sur un récipient à col, totalement retirable. Ce dispositif comprend une bague externe conformée pour recouvrir le bouchon et entourer la collerette supérieure du col du récipient. Il comprend également une bague interne en forme d'anneau, apte à être logée dans la bague externe et pourvue de crans internes inférieurs destinés à prendre appui sous ladite collerette pour se fixer sur le récipient. La bague interne comprend également des crans externes permettant sa solidarisation dans la bague externe. Une telle coiffe permet de bloquer un bouchon dans le col du récipient, ledit bouchon étant maintenu dans la bague interne.We know the document EP2814752 which offers a cap locking device on a container with a neck, completely removable. This device comprises an outer ring shaped to cover the stopper and surround the upper flange of the neck of the container. It also comprises an internal ring in the form of a ring, suitable for being housed in the external ring and provided with lower internal notches intended to bear under said flange in order to be fixed on the container. The inner ring also includes outer notches allowing it to be secured in the outer ring. Such a cap makes it possible to block a stopper in the neck of the container, said stopper being held in the internal ring.

Ces dispositifs de verrouillage sont usuellement utilisés pour conserver des produits pharmaceutiques dans des flacons. Certains produits sont prélevés à l'aide d'une seringue, enfoncée à travers le bouchon en élastomère, après retrait d'une capsule de protection en partie supérieure du dispositif de verrouillage. D'autres produits nécessitent l'ouverture complète de la bouteille pour en être extraits ou pour être reconstitués.These locking devices are commonly used to store pharmaceuticals in vials. Some products are taken using a syringe, inserted through the elastomer stopper, after removing a protective cap from the upper part of the locking device. Other products require the full opening of the bottle to be extracted or to be reconstituted.

Le document précité prévoit une zone frangible, au niveau de la bague externe du dispositif de verrouillage, apte à être cassée pour autoriser l'ouverture de ladite bague et son retrait par rapport à la collerette du récipient. La bague interne est quant à elle pourvue d'un pontet déformable et sécable, apte à être cassé pour autoriser le retrait de ladite bague par rapport à la collerette, autorisant l'accès au bouchon et son retrait du col du récipient.The aforementioned document provides a frangible zone, at the level of the outer ring of the locking device, capable of being broken in order to allow the opening of said ring and its withdrawal with respect to the collar of the container. The internal ring is for its part provided with a deformable and breakable bridge, capable of being broken to allow the removal of said ring relative to the flange, allowing access to the stopper and its removal from the neck of the container.

Un inconvénient de cette solution vient du manque de répétabilité de l'ouverture entre deux dispositifs, en particulier de la rupture du pontet déformable sécable, car il est difficile de tirer de façon répétable sur la bague interne jusqu'à rupture du pontet. Un autre inconvénient de cette solution vient du manque de répétabilité de l'assemblage entre les bagues interne et externe, lequel assemblage doit assurer l'étanchéité de la fermeture.A drawback of this solution comes from the lack of repeatability of the opening between two devices, in particular from the breaking of the breakable deformable bridge, because it is difficult to pull repeatedly on the inner ring until the bridge breaks. Another drawback of this solution comes from the lack of repeatability of the assembly between the inner and outer rings, which assembly must ensure the tightness of the closure.

Le document EP2464577 présente un dispositif de verrouillage d'un bouchon dans le col d'un récipient fiable et répétable en termes d'étanchéité de fermeture mais ne permettant pas le retrait complet dudit dispositif pour extraire le bouchon.The document EP2464577 presents a device for locking a stopper in the neck of a container which is reliable and repeatable in terms of closure sealing but does not allow the complete removal of said device to extract the stopper.

Ce dispositif comprend les caractèristiques du préambule de la revendication 1.This device comprises the characteristics of the preamble of claim 1.

Le document US5269429 propose un capuchon de fermeture comprenant un point de rupture, de manière à permettre le retrait dudit capuchon.The document US5269429 provides a closure cap comprising a breaking point, so as to allow removal of said cap.

La présente invention concerne une coiffe de verrouillage 100 pour un récipient 200 à col, destinée à bloquer un bouchon 10 dans le col 201 dudit récipient 200. Le récipient 200 peut en particulier adopter la forme d'un flacon, présentant un col 201 d'ouverture circulaire, se terminant par une collerette 202 évasée par rapport au périmètre extérieur du col 201. En d'autres termes, le diamètre extérieur de la collerette 202 est supérieur au diamètre extérieur du col 201, comme illustré sur les figures la,lb.The present invention relates to a locking cap 100 for a container 200 with a neck, intended to block a stopper 10 in the neck 201 of said container 200. The container 200 may in particular take the form of a bottle, having a neck 201 of. circular opening, terminating in a flange 202 flared with respect to the outer perimeter of the neck 201. In other words, the outer diameter of the flange 202 is greater than the outer diameter of the neck 201, as illustrated in Figures la, lb.

Dans le domaine des applications pharmaceutiques, il existe des standards en termes de diamètre intérieur de col 201 de récipient 200 : 13mm et 20mm en sont des exemples.In the field of pharmaceutical applications, there are standards in terms of the inside diameter of the neck 201 of the container 200: 13mm and 20mm are examples.

Le bouchon 10 présente une section circulaire et une forme en T avec une tête 11 et un pied 12, la tête 11 étant de diamètre supérieur au pied 12. Ainsi, lorsque le pied 12 du bouchon 10 est complètement enfoncé dans le col 201, la tête 11 se bloque contre la collerette 202.The stopper 10 has a circular section and a T-shape with a head 11 and a foot 12, the head 11 having a diameter greater than the foot 12. Thus, when the foot 12 of the stopper 10 is completely inserted into the neck 201, the head 11 locks against the collar 202.

Notons que lorsque le contenu du flacon est destiné à être lyophilisé, le bouchon 10 présente une ouverture 13 dans son pied 12, pour permettre le passage des flux évaporatoires tant que le bouchon 10 n'est pas complètement enfoncé dans le col 202 (figures 1b et 1d).Note that when the contents of the bottle is intended to be lyophilized, the stopper 10 has an opening 13 in its base 12, to allow the passage of the evaporative flows as long as the stopper 10 is not completely inserted into the neck 202 ( figures 1b and 1d ).

La coiffe 100, lorsqu'elle est associée au bouchon 10, est susceptible d'adopter deux positions sur le récipient 200 : une première position, dite de maintien intermédiaire dans laquelle le bouchon 10 est partiellement enfoncé dans le col 201 (figures 1a, 1b). C'est dans cette position que le récipient 200 peut être soumis à une étape de lyophilisation, car l'enfoncement partiel du bouchon permet à aux flux évaporatoires de transiter à travers l'ouverture 13 aménagée dans le pied 12 du bouchon 10. Nous décrirons plus loin les caractéristiques avantageuses de la coiffe 100 qui permettent la circulation efficace de ces flux évaporatoires.The cap 100, when it is associated with the stopper 10, is capable of adopting two positions on the container 200: a first position, called the intermediate holding position, in which the stopper 10 is partially inserted into the neck 201 ( figures 1a, 1b ). It is in this position that the container 200 can be subjected to a freeze-drying step, because the partial depression of the stopper allows the evaporative flows to pass through the opening 13 made in the base 12 of the stopper 10. We will describe further on the advantageous characteristics of the cap 100 which allow the efficient circulation of these evaporative flows.

La coiffe 100 associée au bouchon 10 peut également adopter une deuxième position, dite de verrouillage, dans laquelle le bouchon 10 est totalement enfoncé, et verrouillé dans le col 201 par la coiffe 100 (figures 1c, 1d). Dans cette position, le bouchon 10 ferme de manière hermétique le récipient 200, le pied 12 (et donc l'ouverture 13 quand elle est présente) se trouvant totalement entouré par le col 201 du récipient 200.The cap 100 associated with the stopper 10 can also adopt a second position, called a locking position, in which the stopper 10 is fully inserted, and locked in the neck 201 by the cap 100 ( figures 1c, 1d ). In this position, the stopper 10 hermetically closes the container 200, the foot 12 (and therefore the opening 13 when it is present) being completely surrounded by the neck 201 of the container 200.

La coiffe 100 comprend un corps externe 30 et une cage 20 configurée pour s'emboiter et se verrouiller axialement dans ledit corps externe 30.The cover 100 comprises an outer body 30 and a cage 20 configured to fit together and lock axially in said outer body 30.

La cage 20 comporte un anneau supérieur 21, une pluralité n de branches 22 reliées à l'anneau supérieur 21 et définissant avec celui-ci une forme générale cylindrique de la cage 20, d'axe central z (figures 2a, 2b).The cage 20 comprises an upper ring 21, a plurality n of branches 22 connected to the upper ring 21 and defining therewith a general cylindrical shape of the cage 20, of central axis z ( figures 2a, 2b ).

La cage 20 comprend également n/2 premiers ponts 25 et n/2 deuxièmes ponts 26, chacun reliant deux branches 22 voisines entre elles. Les premiers ponts 25 et les deuxièmes ponts 26 sont disposés en alternance sur le pourtour de la cage 20. Dans les exemples illustrés sur les figures 2a et 2b, la cage comporte six branches 22, trois premiers ponts 25 et trois deuxièmes ponts 26.The cage 20 also includes n / 2 first bridges 25 and n / 2 second bridges 26, each connecting two neighboring branches 22 between them. The first bridges 25 and the second bridges 26 are arranged alternately around the perimeter of the cage 20. In the examples illustrated on the figures 2a and 2b , the cage has six branches 22, three first bridges 25 and three second bridges 26.

De manière avantageuse, les premiers ponts 25 occupent entre 20% et 40% du périmètre de la cage 20, par exemple 30% ; et les deuxièmes ponts 26 occupent entre 40% et 70% dudit périmètre, par exemple 60%. Le périmètre résiduel pour atteindre 100% est occupé par les branches 22.Advantageously, the first bridges 25 occupy between 20% and 40% of the perimeter of the cage 20, for example 30%; and the second bridges 26 occupy between 40% and 70% of said perimeter, for example 60%. The residual perimeter to reach 100% is occupied by branches 22.

Préférentiellement, la cage 20 comprend une pluralité de premières languettes 23, chacune étant supportée par un premier pont 25. Chaque première languette 23 est flexible et inclinée par rapport aux branches 22 vers l'intérieur de la cage 20, d'un angle compris entre 20° et 60°, avantageusement autour de 45°, en direction de l'anneau supérieur 21.Preferably, the cage 20 comprises a plurality of first tongues 23, each being supported by a first bridge 25. Each first tongue 23 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, at an angle between 20 ° and 60 °, advantageously around 45 °, in the direction of the upper ring 21.

Ces premières languettes 23 sont destinées à bloquer le bouchon 10 à l'intérieur de la cage 20, contre l'anneau supérieur 21, lorsque le bouchon 10 est associé à la coiffe 100. Les premières languettes 23 fléchissent pour laisser passer la tête 11 du bouchon 10 lorsque celui-ci est introduit dans la cage 20, et viennent se bloquer sous la tête 11, pour empêche le bouchon 10 de s'extirper de ladite cage 20.These first tabs 23 are intended to block the stopper 10 inside the cage 20, against the upper ring 21, when the stopper 10 is associated with the cap 100. The first tabs 23 flex to allow the head 11 of the device to pass through. stopper 10 when the latter is introduced into the cage 20, and come to be blocked under the head 11, to prevent the stopper 10 from coming out of said cage 20.

Grâce à ces premières languettes 23, le bouchon 10 reste bien solidaire de la coiffe 100 et aucune séparation accidentelle entre bouchon 10 et coiffe 100 ne peut s'opérer, en particulier, lorsque la coiffe 100 est dans sa position de maintien intermédiaire sur le récipient 200.Thanks to these first tabs 23, the cap 10 remains firmly attached to the cap 100 and no accidental separation between cap 10 and cap 100 can take place, in particular, when the cap 100 is in its intermediate holding position on the container. 200.

La cage 20 comprend avantageusement une pluralité de deuxièmes languettes 24, chacune supportée par un deuxième pont 26. Chaque deuxième languette 24 est flexible et inclinée par rapport aux branches 22 vers l'intérieur de la cage 20, d'un angle compris entre 20° et 60°, avantageusement autour de 30°, en direction de l'anneau supérieur 21.The cage 20 advantageously comprises a plurality of second tongues 24, each supported by a second bridge 26. Each second tongue 24 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, with a angle between 20 ° and 60 °, advantageously around 30 °, in the direction of the upper ring 21.

Ces deuxièmes languettes 24 sont destinées à demeurer au-dessus de la collerette 202, un peu surélevées ou en contact sur celle-ci, lorsque la coiffe 100 est dans la position de maintien intermédiaire (figure 1a). Dans cette position de maintien intermédiaire, les deuxièmes ponts 26 et les branches 22 sont destinés à entourer au moins en partie la collerette 202. Cette configuration permet un maintien mécanique plus stable et sécurisé de l'ensemble bouchon 10 / coiffe 100, durant de potentielles étapes de lyophilisation.These second tabs 24 are intended to remain above the collar 202, slightly raised or in contact thereon, when the cap 100 is in the intermediate holding position ( figure 1a ). In this intermediate holding position, the second bridges 26 and the branches 22 are intended to at least partially surround the collar 202. This configuration allows a more stable and secure mechanical holding of the plug 10 / cap 100 assembly, during potentials. lyophilization steps.

Par ailleurs, les deuxièmes languettes 24 sont destinées à prendre appui sous la collerette 202 du col 201 du récipient 200, lorsque la coiffe 100 est dans la position de verrouillage (figures 1c). En effet, lors du passage en position verrouillée, l'ensemble bouchon 10 / coiffe 100 va descendre dans / autour du col 201 du récipient 200, de manière à enfoncer complètement le pied 12 du bouchon 10 dans le col 201, jusqu'à ce que sa tête 11 s'appuie sur la collerette 202. Lors de l'enfoncement, les deuxièmes languettes 24 fléchissent et s'effacent pour laisser passer la collerette 202, et viennent se bloquer sous cette dernière, verrouillant ainsi le bouchon 10 sur le récipient 200.Furthermore, the second tabs 24 are intended to bear under the collar 202 of the neck 201 of the container 200, when the cap 100 is in the locking position ( figures 1c ). Indeed, during the passage in the locked position, the cap 10 / cap 100 assembly will descend into / around the neck 201 of the container 200, so as to completely depress the foot 12 of the stopper 10 in the neck 201, until that its head 11 rests on the collar 202. When driving in, the second tabs 24 flex and retract to allow the collar 202 to pass through, and come to be blocked under the latter, thus locking the stopper 10 on the container 200.

Notons que, en position de verrouillage, les premières languettes 23 s'effacent car elles se trouvent en appui contre la bordure périphérique de la collerette 202. Elles ne restent donc pas sous la tête 11 du bouchon 10 et laissent celle-ci prendre appui sur la collerette 202. Les premiers ponts 25 entourent alors la bordure périphérique de la collerette 202.Note that, in the locked position, the first tabs 23 are erased because they are resting against the peripheral edge of the collar 202. They therefore do not remain under the head 11 of the plug 10 and let the latter rest on the collar 202. The first bridges 25 then surround the peripheral edge of the collar 202.

Avantageusement, les deuxièmes languettes 24 sont configurées pour autoriser un passage de la position de maintien intermédiaire à la position de verrouillage de la coiffe 100 associée au bouchon 10, lorsqu'une force faible comprise entre 30 N et 70 N, préférentiellement entre 30N et 50N, est appliquée sur la coiffe 100. Pour cela, les deuxièmes languettes 24 présentent une inclinaison par rapport aux branches 22 de l'ordre 20° à 60°, une épaisseur entre 0.6 et 1.3mm et une flexibilité conférée par le choix du matériau formant la cage 20.Advantageously, the second tabs 24 are configured to allow a passage from the intermediate holding position to the locking position of the cover 100 associated with the stopper 10, when a low force between 30 N and 70 N, preferably between 30N and 50N , is applied on the cap 100. For this, the second tabs 24 have an inclination relative to the branches 22 of the order of 20 ° to 60 °, a thickness between 0.6 and 1.3mm and a flexibility conferred by the choice of the material forming the cage 20 .

Cette configuration avantageuse, grâce à laquelle le passage en position de verrouillage est rendu possible par application d'une force de faible amplitude, permet de verrouiller collectivement une pluralité de coiffes 100 sur leurs récipients 200 respectifs, au moyen d'un plateau exerçant une force en partie supérieure de la pluralité de coiffes 100. Cette force de fermeture faible permet aussi de compenser les importantes variations de hauteur des récipients 200 et d'arriver ainsi à une fermeture de l'intégralité desdits récipients présents sous le plateau de fermeture sans générer de casse.This advantageous configuration, thanks to which the passage into the locking position is made possible by applying a force of low amplitude, makes it possible to collectively lock a plurality of caps 100 on their respective containers 200, by means of a plate exerting a force. in the upper part of the plurality of caps 100. This low closing force also makes it possible to compensate for the large variations in height of the containers 200 and thus to achieve closure of all of said containers present under the closing plate without generating any broken.

La coiffe de verrouillage 100 selon la présente invention est complètement retirable et permet le retrait du bouchon 10 pour une ouverture totale du récipient.The locking cap 100 according to the present invention is completely removable and allows the removal of the stopper 10 for full opening of the container.

La cage 20 comprend au moins un deuxième pont 26 supportant une languette d'ouverture 27 inclinée vers l'extérieur de la cage 20, en direction de l'anneau supérieur 21. Le (au moins un) deuxième pont 26 présente en outre une zone sécable 28 adjacente à ladite languette d'ouverture 27 (figures 2a, 2b).The cage 20 comprises at least one second bridge 26 supporting an opening tab 27 inclined towards the outside of the cage 20, in the direction of the upper ring 21. The (at least one) second bridge 26 also has a zone breakable 28 adjacent to said opening tab 27 ( figures 2a, 2b ).

Le corps externe 30 présente lui aussi une partie sécable 35 (figures 3a, 3b). Le corps externe 30 se présente sous une forme générale cylindrique d'axe central z. Une extrémité 30a du corps externe 30 est fermée et l'autre extrémité 30b est ouverte. L'extrémité ouverte 30b est prévue pour accueillir la cage 20, qui viendra s'emboiter dans le corps externe 30, disposant l'anneau supérieur 21 contre la surface intérieure de l'extrémité fermée 30a. La partie sécable 35 pourra par exemple consister en une portion de l'extrémité fermée 30a et de la paroi cylindrique, ladite portion étant délimitée par une double rainure au niveau de laquelle l'épaisseur du corps externe 30 est réduite (figure 3b).The outer body 30 also has a breakable part 35 ( figures 3a, 3b ). The outer body 30 is in a generally cylindrical shape with a central axis z. One end 30a of the outer body 30 is closed and the other end 30b is open. The open end 30b is designed to accommodate the cage 20, which will fit into the outer body 30, placing the upper ring 21 against the inner surface of the closed end 30a. The breakable part 35 may for example consist of a portion of the closed end 30a and of the cylindrical wall, said portion being delimited by a double groove at which the thickness of the outer body 30 is reduced ( figure 3b ).

Le corps externe 30 est configuré pour entourer complètement la cage 20 lorsque cette dernière est emboitée, de manière à empêcher tout accès à ladite cage 20 par l'extérieur, lorsque la coiffe 100 verrouille le bouchon 10 sur le récipient 200. Dans la position de verrouillage de la coiffe 100, le corps externe 30 interdit donc notamment l'accès à la languette d'ouverture 27.The outer body 30 is configured to completely surround the cage 20 when the latter is fitted, so as to prevent any access to said cage 20 from the outside, when the cap 100 locks the stopper 10 on the container 200. In the position of locking the cover 100, the outer body 30 therefore prevents in particular access to the opening tab 27.

Une capsule 32, illustrée sur les figures 3c et 3d, est fixée sur la surface externe de l'extrémité fermée 30a du corps externe 30. Pour cela, la capsule 32 peut comporter un tenon destiné à traverser un orifice (visible sur la figure 3a) présent par exemple au centre de l'extrémité fermée 30a du corps externe 30, et en particulier dans la portion de l'extrémité appartenant à la partie sécable 35. La fixation entre la capsule 32 et le corps externe 30 pourra se faire par bouterollage.A capsule 32, illustrated on figures 3c and 3d , is fixed to the outer surface of the closed end 30a of the outer body 30. For this, the capsule 32 may include a tenon intended to pass through an orifice (visible on the figure 3a ) present for example at the center of the closed end 30a of the outer body 30, and in particular in the portion of the end belonging to the breakable part 35. The fixing between the cap 32 and the outer body 30 can be done by snap-fastening .

En pratique, lorsque l'on souhaite accéder au contenu du récipient 200, on soulève un bord de la capsule 32 pour s'en saisir et exercer un effort d'arrachement. Cet effort est transmis de la capsule 32 à la partie sécable 35 par l'intermédiaire du tenon bouterollé dans l'orifice de l'extrémité fermée 30a du corps externe 30. Cet effort, s'il est suffisant, va induire une rupture au niveau de la double rainure, du fait de son épaisseur réduite. Une portion de l'extrémité fermée 30a et de la paroi cylindrique du corps externe 30 étant supprimée, le corps externe 30 peut être aisément retiré.In practice, when it is desired to access the contents of the container 200, an edge of the capsule 32 is lifted in order to grip it and exert a tearing force. This force is transmitted from the capsule 32 to the breakable part 35 by means of the tenon snapped into the orifice of the closed end 30a of the outer body 30. This force, if it is sufficient, will induce a rupture at the level. of the double groove, due to its reduced thickness. With a portion of the closed end 30a and the cylindrical wall of the outer body 30 removed, the outer body 30 can be easily removed.

Cela donne accès à la cage 20 qui verrouille le bouchon 10 dans le col 201 du récipient 200. Rappelons que la languette 27 d'ouverture est initialement élaborée de sorte qu'elle soit inclinée vers l'extérieur de la cage 20, en direction de l'anneau supérieur 21 ; du fait de ses propriétés élastiques, elle est apte à se rabattre parallèlement aux parois intérieures du corps externe 30, lorsque la cage 20 est verrouillée axialement dans le corps externe 30. Lorsque le corps externe 30 est retiré, la languette 27 d'ouverture retrouve avantageusement son inclinaison initiale, vers l'extérieur de la cage 20, ce qui facilite sa préhension par l'utilisateur. La languette d'ouverture 27 présente avantageusement une forme allongée, qui facilite d'autant plus la préhension.This gives access to the cage 20 which locks the stopper 10 in the neck 201 of the container 200. Remember that the opening tab 27 is initially designed so that it is inclined towards the outside of the cage 20, in the direction of the upper ring 21; due to its elastic properties, it is able to fold back parallel to the inner walls of the outer body 30, when the cage 20 is axially locked in the outer body 30. When the outer body 30 is withdrawn, the opening tab 27 is recovered. advantageously its initial inclination, towards the outside of the cage 20, which facilitates its gripping by the user. The opening tab 27 advantageously has an elongated shape, which makes gripping all the more easier.

La préhension et l'application d'un force en tension sur la languette d'ouverture 27 provoque la casse au niveau de la zone sécable 28 du deuxième pont 26 : la cage 20 peut alors être aisément désolidarisée du col 201 du récipient 200 laissant libre accès au retrait du bouchon 10.The gripping and the application of a tension force on the opening tab 27 causes the breakage at the level of the breakable zone 28 of the second bridge 26: the cage 20 can then be easily detached from the neck 201 of the container 200 leaving free access to removing the cap 10.

La languette d'ouverture 27, de par sa forme, son inclinaison et sa localisation par rapport à la zone sécable 28 formée sur un deuxième pont 26, favorise une rupture fiable et répétable sur une pluralité de cages 20.The opening tongue 27, by virtue of its shape, its inclination and its location relative to the breakable zone 28 formed on a second bridge 26, promotes reliable and repeatable rupture on a plurality of cages 20.

Revenant à la description d'autres éléments de la coiffe 100 selon l'invention, le corps externe 30 comprend une rainure 31 circulaire, aménagée dans ses parois intérieures cylindriques et apte à coopérer avec des moyens complémentaires de la cage 20, pour verrouiller axialement la cage 20 dans le corps externe 30 (figure 3b). Ces moyens sont, par exemple, des crans 221 disposées sur les branches 22 de la cage 20 (visibles sur les figures 2a et 2b) et prévus pour venir se bloquer dans la rainure 31, lorsque la cage 20 est complètement introduite dans le corps externe 30. Le corps externe 30 peut ainsi tourner librement autour de l'axe central z, lorsque la coiffe 100 est en position de verrouillage sur le récipient 200, sans endommager la cage 20 et risquer d'affecter la fiabilité et l'étanchéité de fermeture du récipient 200.Returning to the description of other elements of the cap 100 according to the invention, the outer body 30 comprises a circular groove 31, formed in its cylindrical inner walls and able to cooperate with complementary means of the cage 20, to axially lock the cage 20 in the outer body 30 ( figure 3b ). These means are, for example, notches 221 arranged on the branches 22 of the cage 20 (visible on the figures 2a and 2b ) and designed to come to lock in the groove 31, when the cage 20 is completely inserted into the outer body 30. The outer body 30 can thus rotate freely around the central axis z, when the cap 100 is in the locking position on the container 200, without damaging the cage 20 and risk affecting the reliability and tightness of closure of the container 200.

Selon un mode de réalisation particulièrement adapté à la mise en œuvre d'étapes de lyophilisation, chaque premier pont 25 est conçu pour ménager un espace ouvert 251 entre lui et la collerette 202, lorsque la coiffe 100 est dans sa position de maintien intermédiaire (figure 2b). La cage 20 présente ainsi n/2 espaces ouverts 251, répartis sur le pourtour de la cage 20, permettant une évacuation efficace des flux évaporatoires lors d'étapes de lyophilisation.According to an embodiment particularly suitable for the implementation of lyophilization steps, each first bridge 25 is designed to provide an open space 251 between it and the flange 202, when the cap 100 is in its intermediate holding position ( figure 2b ). The cage 20 thus has n / 2 open spaces 251, distributed around the periphery of the cage 20, allowing efficient evacuation of the evaporative flows during lyophilization steps.

Avantageusement, chaque espace ouvert 251 présente une hauteur, selon la direction axiale z, comprise entre 0,2mm et 2mm, et une largeur, selon le périmètre de la cage 20, sensiblement égale à la largeur d'un premier pont 25. La hauteur de l'espace ouvert 251 peut-être défini comme la distance, selon la direction axiale z, entre le premier pont 25 et une ligne marquant le début de l'inclinaison des deuxièmes languettes 24 vers l'intérieur de la cage 20. En effet, c'est au niveau de cette ligne de début d'inclinaison que le contact entre la collerette 202 et les deuxièmes languettes 24 est susceptible de s'établir, définissant ainsi la position de maintien intermédiaire.Advantageously, each open space 251 has a height, in the axial direction z, of between 0.2mm and 2mm, and a width, according to the perimeter of the cage 20, substantially equal to the width of a first bridge 25. The height of the open space 251 can be defined as the distance, in the axial direction z, between the first bridge 25 and a line marking the start of the inclination of the second tabs 24 towards the inside of the cage 20. Indeed , it is at this line of the start of inclination that the contact between the collar 202 and the second tongues 24 is likely to be established, thus defining the intermediate holding position.

Les différents éléments formant la coiffe 100 selon la présente invention (cage 20, corps externe 30, capsule 32) sont préférentiellement réalisés par moulage d'une matière plastique, compatible avec les procédés de lyophilisation (lorsque requis), avec les procédés de stérilisation gamma, autoclave et à l'oxyde d'éthylène (ETO), et avec les domaines d'applications visés. Par exemple, la cage 20, le corps externe 30 et la capsule 32 pourront être formés à partir de matériaux tels que le polycarbonate (PC), le polypropylène (PP) ou le polytéréphtalate de butylène (PBT). Notons que la capsule 32 pourra être formée à partir de matériaux plastiques souples tels que, par exemple, le polypropylène (PP), pour faciliter sa préhension.The various elements forming the cap 100 according to the present invention (cage 20, outer body 30, capsule 32) are preferably made by molding a plastic material, compatible with lyophilization processes (when required), with gamma sterilization processes. , autoclave and ethylene oxide (ETO), and with the intended fields of application. For example, the cage 20, the outer body 30 and the capsule 32 could be formed from materials such as polycarbonate (PC), polypropylene (PP) or polybutylene terephthalate (PBT). Note that the capsule 32 may be formed from flexible plastic materials such as, for example, polypropylene (PP), to facilitate its gripping.

On notera aussi que, comme le bouchon 10 peut être introduit dans la coiffe 100 après assemblage de la cage 20, du corps externe 30 et de la capsule 32 formant la coiffe 100, on peut avantageusement stocker séparément la coiffe de verrouillage 100 et le bouchon avant utilisation.It will also be noted that, as the cap 10 can be inserted into the cap 100 after assembly of the cage 20, the outer body 30 and the cap 32 forming the cap 100, the locking cap 100 and the cap can advantageously be stored separately. before use.

Bien entendu, l'invention n'est pas limitée aux modes de mise en œuvre et exemples décrits, et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiments and examples described, and variant embodiments can be provided without departing from the scope of the invention as defined by the claims.
