Description

L'invention concerne un récipient contenant un fluide, ainsi qu'un procédé d'ouverture dudit récipient.The invention relates to a container containing a fluid, and to a method of opening said container.

L'invention s'applique notamment, mais non exclusivement, aux récipients contenant une solution stérile destinée à un usage médical unique.The invention is particularly, but not exclusively, applicable to containers containing a sterile solution for a single medical use.

On connaît d'une part des récipients semi-rigides thermoformés réalisés avec un matériau polymère stérilisable, tel que le PET. Ces récipients sont par exemple fermés par des bouchons vissés ou encliquetés qui doivent être manipulés par un utilisateur pour l'ouverture du récipient, ce qui présente un certain nombre d'inconvénients en ce qui concerne l'asepsie.Thermoformed semi-rigid containers made with a sterilizable polymeric material, such as PET, are known on the one hand. These containers are for example closed by screwed or snap-on plugs which must be handled by a user for the opening of the container, which has a number of disadvantages with respect to asepsis.

Le document US-A-5 312 189 décrit un récipient ayant toutes les caracteristiques du préambule de la revendication 1.The document US-A-5,312,189 discloses a container having all the features of the preamble of claim 1.

On connaît également des récipients souples, formés par la solidarisation d'au moins deux feuilles au voisinage de leur périphérie (ou par une feuille repliée dont les deux portions sont solidarisées l'une à l'autre), de sorte à former deux parois latérales et, éventuellement, un fond permettant le maintien vertical du récipient. De tels récipients sont par exemple décrits dans le document FR-A-2 215 359 .Flexible containers are also known, formed by the joining of at least two sheets in the vicinity of their periphery (or by a folded sheet whose two portions are secured to one another), so as to form two side walls. and, optionally, a bottom for maintaining the vertical container. Such containers are for example described in the document FR-A-2,215,359 .

Pour pouvoir vider ces récipients souples, l'utilisateur doit découper un coin du récipient afin de créer un orifice de vidange.In order to empty these flexible containers, the user has to cut a corner of the container to create a drain hole.

Pour faciliter la vidange, certains récipients souples sont munis d'un bec verseur constitué d'un tube surmonté d'un bouchon amovible. Comme décrit dans le document WO-A-01/98167 , le bec verseur peut être recouvert d'une enveloppe afin de le protéger de la pollution. Dans cette réalisation, le bouchon et l'enveloppe sont deux organes dissociés, et possèdent des fonctions distinctes (respectivement boucher et protéger).To facilitate emptying, some flexible containers are provided with a spout consisting of a tube surmounted by a removable cap. As described in the document WO-A-01/98167 , the spout can be covered with an envelope to protect it from pollution. In this embodiment, the cap and the envelope are two dissociated organs, and have distinct functions (respectively clog and protect).

Cependant, pour ouvrir ces récipients, un utilisateur doit dans un premier temps détacher l'enveloppe protectrice, afin de pouvoir accéder au bouchon amovible, puis manipuler ce bouchon pour permettre de dégager l'ouverture du tube.However, to open these containers, a user must first detach the protective envelope, in order to access the removable cap, then manipulate the cap to clear the opening of the tube.

Ainsi, il existe un risque de pollution de l'orifice de vidange et donc de la solution contenue dans les récipients. Si la solution est destinée à un usage médical, cette pollution augmente le risque de contamination et d'apparition d'infections de type nosocomiales.Thus, there is a risk of pollution of the drain hole and therefore of the solution contained in the containers. If the solution is intended for medical use, this pollution increases the risk of contamination and the appearance of nosocomial infections.

En outre, les récipients contenant des solutions médicales sont généralement à usage unique, c'est-à-dire qu'ils doivent être utilisés ou jetés après usage. Les récipients semi-rigides ou souples fermés par un simple bouchon ne peuvent garantir cet usage unique, puisqu'il est possible de refermer les récipients après une utilisation incomplète.In addition, containers containing medical solutions are generally single-use, that is, they must be used or discarded after use. Semi-rigid or flexible containers closed by a simple plug can not guarantee this unique use, since it is possible to close the containers after incomplete use.

Enfin, dans le cas d'un récipient souple, une fois le récipient ouvert, il existe trois éléments séparés les uns des autres, à savoir le récipient en lui-même, le bouchon, et l'enveloppe protectrice. Ceci est peu pratique, en particulier si le bouchon peut être réutilisé pour refermer le récipient tandis que l'enveloppe doit être jetée.Finally, in the case of a flexible container, once the container is open, there are three elements separated from each other, namely the container itself, the cap, and the protective envelope. This is impractical, especially if the cap can be reused to close the container while the envelope has to be discarded.

L'invention propose donc un récipient muni d'un dispositif verseur et d'un organe de fermeture, simple de fabrication et d'utilisation, qui assure une protection efficace contre la pollution des parties en contact avec la solution lors de la vidange du récipient. De plus, une fois le récipient selon l'invention ouvert, il n'est pas possible de le refermer, de sorte que l'usage unique du récipient est garanti.The invention therefore proposes a container provided with a pouring device and a closure member, simple to manufacture and use, which provides effective protection against pollution of the parts in contact with the solution during the emptying of the container. . In addition, once the container according to the invention is open, it is not possible to close it, so that the unique use of the container is guaranteed.

Selon un premier aspect, l'invention porte sur un récipient comprenant :

  • une enveloppe principale définissant une première chambre contenant ou destinée à contenir un fluide, en particulier à usage médical ;
  • un dispositif verseur comprenant un corps tubulaire formant passage de déversement du fluide, ledit corps tubulaire présentant une extrémité amont fixée à l'enveloppe principale de sorte à mettre en communication fluidique la première chambre avec l'extérieur de l'enveloppe principale, et une extrémité aval par laquelle le fluide peut être déversé ;
  • un organe de fermeture du dispositif verseur, ledit organe comprenant un moyen de fermeture de l'extrémité aval du corps tubulaire ;
l'organe de fermeture comprenant en outre une enveloppe de protection qui est associée de façon étanche d'une part au moyen de fermeture, par des moyens d'association fixes, et d'autre part à l'enveloppe principale, par des moyens d'association détachables, ladite enveloppe de protection étant agencée pour former, avec l'enveloppe principale, une deuxième chambre dans laquelle est logé le dispositif verseur.According to a first aspect, the invention relates to a container comprising:
  • a main envelope defining a first chamber containing or intended to contain a fluid, in particular for medical use;
  • a pouring device comprising a tubular body forming a fluid discharge passage, said tubular body having an upstream end secured to the main casing so as to fluidly communicate the first chamber with the outside of the main casing, and an end downstream through which the fluid can be discharged;
  • a closure member of the pouring device, said member comprising means for closing the downstream end of the tubular body;
the closure member further comprising a protective envelope which is sealingly associated on the one hand with the closure means, by fixed association means, and on the other hand with the main envelope, by means of detachable association, said protective envelope being arranged to form, with the main envelope, a second chamber in which is housed the pouring device.

Selon un deuxième aspect, l'invention a pour objet un procédé pour ouvrir un récipient selon le premier aspect de l'invention, dans lequel l'organe de fermeture est actionné de sorte à séparer le moyen de fermeture du corps tubulaire et à détacher l'enveloppe de protection de l'enveloppe principale, de façon à ouvrir l'extrémité aval du corps tubulaire et à permettre le déversement du fluide à l'extérieur du récipient.According to a second aspect, the subject of the invention is a method for opening a container according to the first aspect of the invention, in which the closure member is actuated so as to separate the closure means from the tubular body and to detach the protective envelope of the main envelope, so as to open the downstream end of the tubular body and to allow the discharge of fluid to the outside of the container.

For example, the fluid is a sterile sterile NaCl or sterile water solution used for washing wounds or worktops in a hospital setting.

Le récipient est idéalement à usage unique, c'est-à-dire qu'il doit être jeté après usage même partiel. Ainsi, après ouverture du récipient, s'il reste de la solution dans le récipient, celle ci doit être jetée avec le récipient et non pas conservée pour une utilisation ultérieure.The container is ideally disposable, that is to say it must be discarded even after partial use. Thus, after opening the container, if there remains solution in the container, it must be discarded with the container and not stored for future use.

En référence à la figure 1, le récipient 1 comprend une enveloppe principale 2 définissant une première chambre contenant ou destinée à contenir un fluide, en particulier à usage médical.With reference to the figure 1 , the container 1 comprises a main envelope 2 defining a first chamber containing or intended to contain a fluid, in particular for medical use.

L'enveloppe principale 2 est souple, rigide ou semi-rigide. Elle est réalisée notamment en matière thermoplastique stérilisable tel que le polychlorure de vinyle ou une polyoléfine, par exemple le polypropylène, le polyéthylène ou un complexe à base de polypropylène.The main envelope 2 is flexible, rigid or semi-rigid. It is made in particular of sterilizable thermoplastic material such as polyvinyl chloride or a polyolefin, for example polypropylene, polyethylene or a complex based on polypropylene.

Selon une première réalisation, l'enveloppe 2 est formée par l'assemblage d'une première et deuxième feuilles souples solidarisées par soudage ou collage l'une à l'autre de sorte à former la première chambre.According to a first embodiment, the casing 2 is formed by assembling a first and second flexible sheet secured by welding or bonding to one another so as to form the first chamber.

Selon une deuxième réalisation illustrée par la figure 2, l'enveloppe principale du récipient comprend en outre un fond permettant le maintien vertical du récipient. Le fond est constitué d'une troisième feuille souple 5 solidarisée aux première et deuxième feuilles souples 3,4.According to a second embodiment illustrated by the figure 2 , the main envelope of the container further comprises a bottom for maintaining the vertical container. The bottom consists of a third flexible sheet 5 secured to the first and second flexible sheets 3,4.

Sur une autre réalisation représentée en figure 3, l'enveloppe principale est constituée d'une unique feuille souple 6 pliée et soudée de façon à former les parois latérales et éventuellement le fond du récipient.On another embodiment represented in figure 3 , the main envelope consists of a single flexible sheet 6 folded and welded to form the side walls and possibly the bottom of the container.

Selon les figures 1 et 1A, le récipient 1 comprend également un dispositif verseur 7 comprenant un corps tubulaire 8 formant passage de déversement du fluide, ledit corps tubulaire présentant une extrémité amont 9 fixée à l'enveloppe principale 2 de sorte à mettre en communication fluidique la première chambre avec l'extérieur de l'enveloppe principale, et une extrémité aval 10 par laquelle le fluide peut être déversé.According to Figures 1 and 1A , the container 1 also comprises a pouring device 7 comprising a tubular body 8 forming a fluid discharge passage, said tubular body having an upstream end 9 fixed to the main casing 2 so as to put in fluid communication the first chamber with the outside of the main envelope, and a downstream end 10 through which the fluid can be discharged.

Selon l'invention, le récipient 2 comprend en outre un organe de fermeture du dispositif verseur, ledit organe comprenant un moyen de fermeture 11 de l'extrémité aval du corps tubulaire, et une enveloppe de protection 12.According to the invention, the container 2 further comprises a closure member of the pouring device, said member comprising a closing means 11 of the downstream end of the tubular body, and a protective envelope 12.

Le moyen de fermeture 11 obture le passage de déversement du fluide formé par le corps tubulaire 8 du dispositif verseur 7, empêchant ainsi le fluide contenu dans la première chambre de s'écouler vers l'extérieur de la première chambre du récipient.The closure means 11 closes the spill passage of the fluid formed by the tubular body 8 of the pouring device 7, thereby preventing the fluid contained in the first chamber from flowing outwardly of the first chamber of the container.

L'enveloppe de protection 12 est associée de façon étanche d'une part au moyen de fermeture 11, par des moyens d'association fixes 13, et d'autre part à l'enveloppe principale, par des moyens d'association détachables 14. L'enveloppe de protection 12 est agencée pour former, avec l'enveloppe principale 2, une deuxième chambre dans laquelle est logé le dispositif verseur 7.The protective envelope 12 is associated sealingly on the one hand with the closure means 11, by fixed association means 13, and on the other hand with the main envelope, by detachable association means 14. The protective envelope 12 is arranged to form, with the main envelope 2, a second chamber in which the pouring device 7 is housed.

L'organe de fermeture possède deux fonctions principales. D'abord, il empêche le déversement du fluide par le corps tubulaire 7 du dispositif verseur. Ensuite, il protège le dispositif verseur 7 de la pollution extérieure.The closure member has two main functions. First, it prevents the spillage of fluid by the tubular body 7 of the pouring device. Then, it protects the pouring device 7 from external pollution.

De par l'association originale de l'enveloppe de protection 12 au moyen de fermeture 11 et à l'enveloppe principale 2, le dispositif verseur 7 ne peut être complètement dégagée de l'enveloppe de protection 12 que lorsque le dispositif verseur 7 est libéré du moyen de fermeture 11, permettant le passage du fluide vers l'extérieur de la première chambre. Et inversement, le dispositif verseur 7 n'est complètement libéré du moyen de fermeture 11 que lorsque le dispositif verseur est dégagé de l'enveloppe de protection 12.By the original combination of the protective envelope 12 with the closure means 11 and the main envelope 2, the pouring device 7 can be completely disengaged from the protective envelope 12 only when the pouring device 7 is released. closing means 11, allowing the passage of fluid to the outside of the first chamber. Conversely, the pouring device 7 is completely released from the closing means 11 only when the pouring device is disengaged from the protective envelope 12.

Ainsi, lorsque le récipient est à usage médical et est stérilisé, l'asepsie du dispositif verseur 7 et en particulier de l'extrémité aval 10 du corps tubulaire 8 est préservée jusqu'au moment de son utilisation, c'est-à-dire du déversement du fluide.Thus, when the container is for medical use and is sterilized, the asepsis of the pouring device 7 and in particular of the downstream end 10 of the tubular body 8 is preserved until the moment of its use, that is to say fluid spill.

L'enveloppe de protection 12 est réalisée notamment en matière thermoplastique stérilisable tel que le polychlorure de vinyle ou une polyoléfine, par exemple le polypropylène, le polyéthylène ou un complexe à base de polypropylène.The protective envelope 12 is made in particular of sterilizable thermoplastic material such as polyvinyl chloride or a polyolefin, for example polypropylene, polyethylene or a complex based on polypropylene.

L'enveloppe de protection est associée de façon étanche à l'enveloppe principale, de sorte que, si le récipient est stérilisé, la deuxième chambre l'est également et le reste jusqu'à l'ouverture du récipient.The protective casing is sealingly associated with the main casing, so that if the container is sterilized, the second chamber is also sterilized and the remainder until the container is opened.

En particulier, le récipient comprend au moins une première et une deuxième feuilles souples solidarisées l'une à l'autre de sorte à former les première et deuxième chambres. La solidarisation est réalisée par soudage ou collage.In particular, the container comprises at least a first and a second flexible sheet secured to one another so as to form the first and second chambers. Bonding is achieved by welding or gluing.

Selon une autre variante de réalisation représentée sur la figure 3, les première et deuxièmes chambres du récipient sont formées d'une seule feuille souple 6, pliée et soudée. Cette réalisation simplifie le procédé de fabrication du récipient.According to another embodiment variant represented on the figure 3 the first and second chambers of the container are formed of a single flexible sheet 6, folded and welded. This embodiment simplifies the manufacturing process of the container.

Sur la figure 1, lorsque l'enveloppe principale 2 présente la forme d'un rectangle dont un coin est tronqué, l'enveloppe de protection 12 est reliée à l'enveloppe principale au niveau dudit coin tronqué.On the figure 1 when the main envelope 2 has the shape of a rectangle whose corner is truncated, the protective envelope 12 is connected to the main envelope at said truncated corner.

En variante non représentée, l'enveloppe principale présente sensiblement la forme d'un rectangle, et l'enveloppe de protection représente une excroissance du rectangle.In variant not shown, the main envelope has substantially the shape of a rectangle, and the protective envelope represents a protrusion of the rectangle.

Dans les différentes réalisations, l'enveloppe principale et l'enveloppe de protection sont associées par des moyens d'association détachables.In the various embodiments, the main envelope and the protective envelope are associated by detachable association means.

Selon la figure 1A, les moyens d'association détachables 14 comprennent par exemple des soudures frangibles ou une amorce de rupture périphérique 15 agencée pour que l'enveloppe de protection 12 puisse être facilement détachée de l'enveloppe principale 2.According to Figure 1A the detachable association means 14 comprise, for example, frangible welds or a peripheral rupture primer 15 arranged so that the protective envelope 12 can be easily detached from the main envelope 2.

L'amorce de rupture est notamment une encoche et/ou une ligne de découpe comprenant des perforations.The incipient fracture is in particular a notch and / or a cutting line comprising perforations.

L'enveloppe de protection 12 est également associée au moyen de fermeture du corps tubulaire 8 du dispositif verseur 7 par des moyens d'associations fixes 13, tels qu'une soudure.The protective envelope 12 is also associated with the means for closing the tubular body 8 of the pouring device 7 by means of fixed associations 13, such as a weld.

En relation avec les figures 1A et 4, le moyen de fermeture comprend un bouchon 16 dont l'extrémité aval 17 est fixée à l'enveloppe de protection 12 et dont l'extrémité amont 18 présente une zone de faiblesse 19 associée à l'extrémité aval 10 du corps tubulaire 8.In relation to Figures 1A and 4 , the closure means comprises a plug 16 whose downstream end 17 is fixed to the protective envelope 12 and whose upstream end 18 has a zone of weakness 19 associated with the downstream end 10 of the tubular body 8.

Le bouchon 16 obture l'extrémité aval 10 du corps tubulaire 8, empêche le déversement du fluide contenu dans la première chambre du récipient 1. Le bouchon 16 comprend par exemple un corps tubulaire plein.The plug 16 closes the downstream end 10 of the tubular body 8, prevents the spillage of the fluid contained in the first chamber of the container 1. The cap 16 comprises for example a solid tubular body.

Lorsque le récipient 2 comprend au moins une première et une deuxième feuilles souples solidarisées l'une à l'autre ou une feuille souple repliée sur elle même de sorte à former les première et deuxième chambres, l'extrémité amont 9 du corps tubulaire et l'extrémité aval 17 du bouchon 16 sont fixées entre les deux feuilles.When the container 2 comprises at least a first and a second flexible sheet secured to one another or a flexible sheet folded on itself to form the first and second chambers, the upstream end 9 of the tubular body and the downstream end 17 of the plug 16 are fixed between the two sheets.

La zone de faiblesse 19 est agencée pour pouvoir être rompue par une action manuelle de sorte à séparer le bouchon 16 du corps tubulaire 8 et permettre le déversement du fluide vers l'extérieur du récipient.The zone of weakness 19 is arranged to be broken by a manual action so as to separate the plug 16 of the tubular body 8 and allow the discharge of fluid to the outside of the container.

Notamment, la zone de faiblesse est susceptible d'être rompue lors d'une sollicitation latérale à travers l'enveloppe de protection.In particular, the zone of weakness is likely to be broken during a lateral bias through the protective envelope.

Comme illustrée sur les figures 1, 1A et 8, la zone de faiblesse 19 et l'amorce de rupture 15 sont décalées axialement l'une par rapport à l'autre de sorte que, lorsque le bouchon 16 et le corps tubulaire 8 ont été séparés par rupture de la zone de faiblesse 19 et l'enveloppe de protection 12 détachée de l'enveloppe principale 2, l'espace entourant le corps tubulaire 8 est dégagé, le déversement du fluide étant facilité.As illustrated on Figures 1, 1A and 8 , the zone of weakness 19 and the rupture primer 15 are offset axially with respect to each other so that, when the plug 16 and the tubular body 8 have been separated by rupture of the zone of weakness 19 and the protective casing 12 detached from the main casing 2, the space surrounding the tubular body 8 is clear, the fluid spill being facilitated.

En outre, ce décalage favorise la non contamination de l'extrémité aval 10 du corps tubulaire par laquelle est déversé le fluide, puisque les moyens d'association détachables 14 de l'enveloppe de protection à l'enveloppe principale sont éloignés de cette extrémité aval.In addition, this offset promotes the non-contamination of the downstream end of the tubular body through which the fluid is discharged, since the detachable association means 14 of the protective envelope to the main envelope are remote from this downstream end. .

En relation avec les figures 4 à 6, le corps tubulaire 8 et le bouchon 16 sont réalisés d'une seule pièce en matière thermoplastique. En variante, le corps tubulaire et le bouchon sont formés de plusieurs pièces assemblées pour former une pièce unitaire.In relation to Figures 4 to 6 , the tubular body 8 and the cap 16 are made in one piece of thermoplastic material. Alternatively, the body tubular and the plug are formed of several pieces assembled to form a unitary piece.

La zone de faiblesse 19 est alors par exemple une zone de plus faible épaisseur que celle du corps tubulaire et du bouchon (fig. 6).The zone of weakness 19 is then, for example, a zone of smaller thickness than that of the tubular body and the plug ( Fig. 6 ).

Selon les figures 4 et 5, l'extrémité amont 9 du corps tubulaire 8 et/ou l'extrémité aval 17 du bouchon 16 comprend une pièce présentant, en coupe transversale, la forme générale d'une ellipse effilée au voisinage des extrémités de son grand axe.According to Figures 4 and 5 , the upstream end 9 of the tubular body 8 and / or the downstream end 17 of the plug 16 comprises a part having, in cross section, the general shape of a tapered ellipse near the ends of its major axis.

Ces pièces ellipsoïdales facilitent la fixation de corps tubulaire et du bouchon à l'enveloppe principale et à l'enveloppe de protection respectivement, notamment lorsque celles ci sont sous forme de feuilles souples.These ellipsoidal parts facilitate the fixation of the tubular body and the cap to the main envelope and the protective envelope respectively, especially when they are in the form of flexible sheets.

Sur les figures 4 et 5, ces pièces ellipsoïdales comprennent des nervures 20 qui augmentent la liaison aux feuilles souples formant les enveloppes principales et de protection.On the Figures 4 and 5 these ellipsoidal pieces comprise ribs 20 which increase the bond to the flexible sheets forming the main and protective envelopes.

Le bouchon comprend en outre une zone sensiblement plane 21 agencée pour faciliter la prise en main de l'organe de fermeture en vue de la rupture de la zone de faiblesse, et une partie tubulaire 22 disposée en prolongement du corps tubulaire, entre la zone de faiblesse 19 et la zone sensiblement plane 21.The stopper further comprises a substantially planar zone 21 arranged to facilitate the grip of the closure member in order to break the zone of weakness, and a tubular portion 22 disposed in extension of the tubular body, between the zone of weakness 19 and the substantially planar area 21.

Dans la réalisation des figures 4 à 6, le bouchon ne peut pas être replacé à l'extrémité aval 10 du dispositif verseur 7, garantissant l'emploi à usage unique du récipient.In the realization of Figures 4 to 6 , the cap can not be replaced at the downstream end 10 of the pouring device 7, guaranteeing the single use of the container.

Selon un réalisation particulière du dispositif verseur représenté sur la figure 7, la partie aval et externe du corps tubulaire 8 est de forme conique, de sorte à former un raccord conique mâle de type Luer.According to a particular embodiment of the pouring device represented on the figure 7 , the downstream and outer portion of the tubular body 8 is conical in shape, so as to form a male conical connector Luer type.

Ce raccord conique mâle est susceptible d'être assemblé à un raccord conique femelle 23 de type Luer d'un dispositif (fig. 10). Un tel dispositif est par exemple une seringue, une aiguille, une tubulure ou un appareil de transfusion ou perfusion.This male conical connection is capable of being assembled to a female Luer-type conical connector 23 of a device ( Fig. 10 ). Such a device is for example a syringe, needle, tubing, or transfusion or infusion apparatus.

Selon un deuxième aspect, on décrit maintenant en relation avec les figures 8 à 10, un procédé pour ouvrir le récipient selon l'invention.According to a second aspect, we now describe in relation to the Figures 8 to 10 , a method for opening the container according to the invention.

Pour ouvrir le récipient 2, l'organe de fermeture est actionné de sorte à séparer le moyen de fermeture 11 du corps tubulaire 8 et à détacher l'enveloppe de protection 12 de l'enveloppe principale 2, de façon à ouvrir l'extrémité aval 10 du corps tubulaire et à permettre le déversement du fluide à l'extérieur du récipient.To open the container 2, the closing member is actuated so as to separate the closure means 11 from the tubular body 8 and to detach the protective casing 12 from the main casing 2, so as to open the downstream end 10 of the tubular body and to allow the discharge of the fluid outside the container.

La séparation du moyen de fermeture et du corps tubulaire, d'une part, et l'action consistant à détacher l'enveloppe de protection de l'enveloppe principale, d'autre part, sont simultanées.The separation of the closure means and the tubular body, on the one hand, and the action of detaching the protective envelope from the main envelope, on the other hand, are simultaneous.

En variante, on sépare tout d'abord le moyen de fermeture du corps tubulaire avant de détacher l'enveloppe de protection de l'enveloppe principale.As a variant, the closure means of the tubular body are first separated before detaching the protective envelope from the main envelope.

En relation avec le mode de réalisation représenté sur la figure 1A, on sépare le bouchon 16 du corps tubulaire 8 par sollicitation latérale, puis on retire l'enveloppe de protection 12 par déchirement au niveau de la découpe. Le corps tubulaire 8 du dispositif verseur est ainsi libéré sans qu'il n'ait été pollué par contact. La solution contenue dans le récipient est ensuite déversée.In connection with the embodiment shown on the Figure 1A , the plug 16 is separated from the tubular body 8 by lateral biasing, then the protective envelope 12 is removed by tearing at the cut. The tubular body 8 of the pouring device is thus released without being polluted by contact. The solution contained in the container is then poured.

En relation avec la figure 10, après séparation du bouchon 16 et de l'enveloppe de protection 12, le dispositif verseur en forme de raccord conique mâle est complètement libéré. Il est alors possible de connecter un raccord conique femelle 23 d'un dispositif approprié, pour vidanger la solution contenue dans le récipient.In relation to the figure 10 after separation of the plug 16 and the protective casing 12, the pouring device in the form of a conical male connector is completely released. It is then possible to connect a female conical connector 23 of a suitable device, to drain the solution contained in the container.

Après l'ouverture et utilisation du récipient, il ne reste que deux déchets, à savoir d'une part le bouchon 16 associé à l'enveloppe de protection 12 et d'autre part l'enveloppe principale 2.After the opening and use of the container, only two wastes remain, namely on the one hand the plug 16 associated with the protective envelope 12 and on the other hand the main envelope 2.
