Description

CONTENANT POUR FLUIDE COMPORTANT UNE POCHE  FLUID CONTAINER COMPRISING A POCKET
DESTINEE A CONTENIR LEDIT FLUIDE, ET FUT ASSOCIE  INTENDED TO CONTAIN THIS FLUID, AND WAS ASSOCIATED
Domaine technique Technical area
L'objet de la présente invention a trait au domaine des contenants pour fluide, et notamment des contenants pour liquide ou pâte.  The subject of the present invention relates to the field of containers for fluid, and in particular containers for liquid or paste.
Plus particulièrement, l'objet de !a présente invention trouve des applications particulièrement avantageuses pour des liquides tels que de la bière ou de l'eau.  More particularly, the object of the present invention finds particularly advantageous applications for liquids such as beer or water.
L'objet de la présente invention trouve également d'autres applications avantageuses notamment dans le domaine de l'agro-alimentaire, de la cosmétique ou encore dans le domaine pharmaceutique, phytosanitaire ou chimique.  The object of the present invention also finds other advantageous applications in particular in the field of food processing, cosmetics or in the pharmaceutical, phytosanitary or chemical field.
Etat de la technique State of the art
Il existe de nombreuses solutions permettant de conditionner, stocker, et/ou transporter des fluides.  There are many solutions for conditioning, storing, and / or transporting fluids.
Généralement, les contenants qui sont inférieurs à un volume de 10 à 20 litres sont pré-rempiis et utilisent le principe de la gravité pour distribuer le fluide qu'ils contiennent.  Generally, containers that are less than a volume of 10 to 20 liters are pre-filled and use the principle of gravity to dispense the fluid they contain.
Dans ce cas, l'utilisateur doit retourner le contenant pour permettre l'écoulement du fluide.  In this case, the user must return the container to allow the flow of fluid.
A titre d'exemple, on connaît les bouteilles d'eau commercialisées sous le format d'un gallon ou d'un gallon et demi.  For example, water bottles marketed in the format of a gallon or a gallon and a half are known.
Pour ce genre de contenants, il faut pivoter le contenant pour que le goulot soit positionné vers le bas en sorte de permettre la distribution de l'eau.  For this type of container, it is necessary to rotate the container so that the neck is positioned downward so as to allow the distribution of water.
On peut également citer l'exemple du mini-fût de bière qui est pré-rempli, qui fonctionne selon le même principe, et qui n'est pas réutilisable.  Another example is the mini-barrel of beer, which is pre-filled, operates on the same principle, and is not reusable.
Ce genre de contenant pour fluide présente de nombreux inconvénients qui sont notamment leur coût de fabrication, le fait qu'ils faillent les manipuler pour permettre la distribution de leur contenu, et le fait qu'ils ne soient pas réutilisables.  This type of fluid container has many disadvantages which are in particular their manufacturing cost, the fact that they fail to manipulate to allow the distribution of their content, and the fact that they are not reusable.
Il existe des contenants qui tentent de résoudre ce genre de problématiques. Le document EP 1 736 421 divulgue un baril pour fluide, également connu sous le nom anglais « keg », comprenant une coque sphérique en plastique résistant à la pression, et à l'intérieur de laquelle on positionne une poche destinée à contenir un fluide. There are containers that try to solve this kind of problem. EP 1 736 421 discloses a fluid barrel, also known as "keg", comprising a pressure-resistant plastic spherical shell, and within which is positioned a pouch for containing a fluid.
La coque présente au niveau de sa portion supérieure une valve reliée à (a poche, cette valve étant destinée à permettre le remplissage de cette poche avec le fluide.  The shell has at its upper portion a valve connected to (a pocket, this valve being intended to allow the filling of this pocket with the fluid.
Le baril selon ce document EP L 736 421 comprend en outre des moyens de support en carton permettant à la fois le support de la coque et la préhension du baril.  The barrel according to this document EP L 736 421 further comprises cardboard support means for both the support of the shell and the gripping of the barrel.
Un tel baril présente de nombreux inconvénients.  Such a barrel has many disadvantages.
La demanderesse soumet notamment que le positionnement de la poche dans une telle coque est très complexe.  The Applicant submits in particular that the positioning of the pocket in such a shell is very complex.
En effet, la poche utilisée dans un tel baril est composée de deux feuilles polygonales flexibles qui sont thermo-soudées entre elles le long de leurs bords.  Indeed, the pocket used in such a barrel is composed of two flexible polygonal sheets which are heat-welded together along their edges.
Lors du thermosoudage de ces deux feuilles, on procède de sorte que la poche comporte entre les deux feuilles des canaux d'acheminement pour permettre l'écoulement uniforme et progressif du fluide dans la poche.  During the heat-sealing of these two sheets, the procedure is such that the bag has between the two sheets of the delivery channels to allow smooth and uniform flow of fluid in the bag.
Cet agencement permet également une bonne vidange du fluide en minimisant le résiduel.  This arrangement also allows good fluid drainage by minimizing the residual.
La vidange se fait « tête en bas », la pression exercée sur la poche pousse le produit via les canaux vers la valve, cette pression pouvant entraîner la rupture de la poche ou du thermosoudage.  The emptying is done "head down", the pressure exerted on the pocket pushes the product via the channels towards the valve, this pressure being able to cause the rupture of the pocket or the heat-sealing.
L'absence de tout élément permettant la distribution du fluide par le bas de la poche impose la formation de tels canaux d'acheminement. Or, la fabrication d'une telle poche, et notamment des canaux d'acheminement, est complexe.  The absence of any element allowing the distribution of the fluid through the bottom of the pocket requires the formation of such routing channels. However, the manufacture of such a pocket, including routing channels, is complex.
Le remplissage se fait quant à lui « tête en haut ».  The filling is done "head up".
Cet agencement nécessite donc de nombreuses manipulations, et notamment de nombreux retournements.  This arrangement therefore requires many manipulations, including many reversals.
On constate également que le positionnement d'une telle poche dans la coque est complexe dans ia mesure où les canaux d'acheminement doivent s'étendre de la valve vers la portion inférieure de la coque pour permettre un remplissage continu et progressif de la poche. It is also noted that the positioning of such a pocket in the hull is complex in that the delivery channels must extend from the valve to the lower portion of the shell to allow continuous and progressive filling of the bag.
Ainsi, sur le plan pratique, l'ensemble formé par la coque sphérique et la poche est complexe et est à usage unique dans la mesure où le positionnement de la poche ne peut pas être fait intuitivement par un simple utilisateur, de tels ensembles étant exclusivement assemblés par leur fabricant lors de leur fabrication.  Thus, in practical terms, the assembly formed by the spherical shell and the pocket is complex and is disposable insofar as the positioning of the pocket can not be done intuitively by a simple user, such sets being exclusively assembled by their manufacturer during their manufacture.
Par ailleurs, les moyens de support qui sont caractéristiques du document EP 1 736 421 ne sont pas adaptés au domaine des fluides, ceci du simple fait que ces moyens sont en carton.  Furthermore, the support means which are characteristic of document EP 1 736 421 are not adapted to the field of fluids, this simply because these means are made of cardboard.
En effet, dans le domaine des fluides, il est fréquent que de tels moyens soient mouillés, ce qui rend les moyens de support inutilisables.  Indeed, in the field of fluids, it is common for such means to be wet, which makes the support means unusable.
La solution proposée ci-dessus est donc une solution ergonomique et esthétique en termes de conditionnement. Toutefois, elle est destinée à un usage unique, les coûts de celles-ci sont prohibitifs, et le remplissage du fluide se fait uniquement en retournant le contenant.  The solution proposed above is therefore an ergonomic and aesthetic solution in terms of packaging. However, it is intended for a single use, the costs of these are prohibitive, and the filling of the fluid is done only by turning the container.
Il existe d'autres solutions plus simples utilisant une poche destinée à contenir un fluide.  There are other simpler solutions using a pocket for containing a fluid.
Toutefois, il est nécessaire que la poche utilisée soit extrêmement propre, voire aseptique, pour pouvoir conditionner le fluide, ceci notamment lorsqu'il s'agit d'un fluide destiné à la consommation ou à une composition pharmaceutique.  However, it is necessary that the bag used is extremely clean or even aseptic, to be able to condition the fluid, especially when it is a fluid for consumption or a pharmaceutical composition.
Comme évoqué ci-dessus, la poche utilisée doit donc être une poche jetable et à usage unique, ou à tout le moins cette poche doit pouvoir être nettoyé facilement.  As mentioned above, the bag used must be a disposable and disposable bag, or at least this bag must be easily cleaned.
Par ailleurs, il est préférable que, lorsqu'il est conditionné dans une poche, le fluide ne perde pas de sa qualité et/ou de ses propriétés physiques, chimiques et/ou aromatiques lors du remplissage.  Furthermore, it is preferable that, when packaged in a pocket, the fluid does not lose its quality and / or its physical, chemical and / or aromatic properties during filling.
Pour pallier au moins partiellement à ces différents inconvénients, ie document FR 2 756 470 divulgue un réservoir destiné à recevoir un volume de liquide, et comprenant un goulot de remplissage, une buse, une enveloppe à capacité extensible constituée dans un élastomère tel que par exemple un éiastomère thermoplastique. Le réservoir selon ce document comporte en outre un organe mécanique agencé à l'intérieur de l'enveloppe par l'intermédiaire d'un système de base et de contre-embase de sorte qu'aucune pression supplémentaire ne soit exercée dans l'enveloppe lors que l'enveloppe se remplit et/ou se vide. To at least partially overcome these various drawbacks, document FR 2 756 470 discloses a reservoir intended to receive a volume of liquid, and comprising a filler neck, a nozzle, an expandable capacity envelope constituted in an elastomer such as for example a thermoplastic elastomer. The reservoir according to this document also comprises a mechanical member arranged inside the envelope via a base and counter-base system so that no additional pressure is exerted in the envelope during that the envelope fills up and / or empties itself.
A cet effet, l'organe mécanique selon le document FR 2 756 470 consiste en une structure linéaire télescopique constituée de plusieurs éléments tubulaires emboîtés les uns dans les autres, et montés en rotation dans le goulot de remplissage.  For this purpose, the mechanical member according to the document FR 2 756 470 consists of a telescopic linear structure consisting of several tubular elements nested in each other, and mounted in rotation in the filler neck.
Cet agencement de l'organe mécanique avec le système de base, contre- embase et enveloppe permet ainsi le développement linéaire de la structure lors du remplissage ou de (a vidange du réservoir.  This arrangement of the mechanical member with the base system, counter-base and envelope thus allows the linear development of the structure during filling or emptying of the tank.
La demanderesse observe donc que, dans ce document, le déploiement du réservoir se fait par l'effet conjoint de l'organe mécanique et de l'enveloppe qui est dans un matériau élastiquement déformable.  The Applicant therefore observes that, in this document, the deployment of the reservoir is done by the joint effect of the mechanical member and the envelope which is in an elastically deformable material.
La demanderesse observe en outre qu'avec un tel agencement la propulsion des liquides se fait par l'élasticité de l'enveloppe qui a tendance à revenir à sa configuration au repos, ce qui implique une pression de sortie qui est fonction de la pression exercée par le liquide sur les parois de l'enveloppe et donc qui est irrégulière tout au long de la vidange.  The Applicant further observes that with such an arrangement the propulsion of the liquids is by the elasticity of the envelope which tends to return to its configuration at rest, which implies an outlet pressure which is a function of the pressure exerted by the liquid on the walls of the envelope and therefore that is irregular throughout the emptying.
Un tel agencement implique donc inévitablement un résiduel dans la mesure où, moins il y a de liquide à l'intérieur de l'enveloppe, moins la pression permettant l'évacuation du liquide est forte. La demanderesse soumet qu'un tel résiduel dans l'enveloppe n'est pas acceptable sur le plan économique.  Such an arrangement therefore inevitably involves a residual insofar as the less liquid there is inside the casing, the less the pressure allowing the evacuation of the liquid is strong. The Applicant submits that such a residual in the envelope is not economically acceptable.
Par ailleurs, la demanderesse soumet que le réservoir selon ce document n'est pas adapté pour permettre un bon stockage ni un bon transport.  Furthermore, the applicant submits that the tank according to this document is not suitable for good storage or transport.
En effet, pour une bonne manutention, et donc un stockage et un transport facile, il est préférable de disposer le contenant dans un fût.  Indeed, for good handling, and therefore easy storage and transport, it is preferable to dispose the container in a drum.
Pour ce faire, il est souhaitable que, pour chaque utilisation, on puisse introduire le contenant vide dans le fût, puis remplir le contenant d'un fluide. Ensuite, une fois vidée, il faut pouvoir ressortir le contenant usée pour pouvoir le remplacer par un nouveau contenant vide, et ainsi de suite. Ceci répond à des contraintes de normes de stockage et de transport et de normes sanitaires. La demanderesse soumet que l'introduction du réservoir selon le document FR 2 756 470 dans un fût présentant une ouverture d'introduction étroite ainsi que son retrait n'est pas facile, voire impossible, au regard du matériau utilisé pour l'enveloppe et de !a structure complexe et fragile de l'organe mécanique. To do this, it is desirable that for each use, we can introduce the empty container into the drum, and fill the container with a fluid. Then, once emptied, it is necessary to be able to leave the used container to be able to replace it by a new empty container, and so on. This meets the constraints of storage and transport standards and sanitary standards. The Applicant submits that the introduction of the tank according to FR 2 756 470 into a drum having a narrow introduction opening and its removal is not easy or impossible with regard to the material used for the envelope and the complex and fragile structure of the mechanical organ.
La demanderesse soumet également que le contrôle sanitaire du réservoir selon ce document n'est pas possible étant donné que l'enveloppe est dans un matériau opaque, et que l'organe mécanique à l'intérieur de l'enveloppe ne permet pas un accès d'une sonde de contrôle à l'intérieur de l'enveloppe.  The applicant also submits that the sanitary control of the tank according to this document is not possible since the envelope is in an opaque material, and that the mechanical member inside the envelope does not allow access to a control probe inside the envelope.
Le réservoir selon le document FR 2 756 470 est donc difficile, voire impossible à nettoyer.  The reservoir according to document FR 2 756 470 is therefore difficult or impossible to clean.
La demanderesse soumet donc qu'il n'existe pas de poche pratique, simple d'utilisation, à moindre de coût, et adaptée pour être introduite aisément dans un fût rigide par une entrée unique étroite.  The applicant therefore submits that there is no practical pocket, easy to use, at less cost, and adapted to be easily introduced into a rigid barrel by a narrow single inlet.
Objet et résumé de la présente invention Object and summary of the present invention
L'objet de l'invention est donc d'apporter une solution aux différents problèmes précités parmi d'autres problèmes, les problèmes de coût et de fabrication étant bien évidemment pris en considération dans le cadre de la présente invention.  The object of the invention is therefore to provide a solution to the various problems mentioned above among other problems, problems of cost and manufacturing being obviously considered in the context of the present invention.
Un des problèmes techniques que résout l'objet de la présente invention consiste notamment en la fabrication d'un contenant pour le conditionnement, le stockage et/ou le transport d'un fluide, l'objet de la présente invention étant notamment adapté pour permettre d'introduire et de retirer aisément un tel contenant dans un fût, et de remplir ou vider aisément et de façon complète ce contenant.  One of the technical problems that the object of the present invention solves consists in particular in the manufacture of a container for the packaging, storage and / or transport of a fluid, the object of the present invention being especially adapted to allow to easily introduce and remove such a container into a drum, and fill or empty this container easily and completely.
L'objet de la présente invention concerne donc un contenant pour fluide adapté à cet effet.  The object of the present invention therefore relates to a fluid container adapted for this purpose.
Selon la présente invention, le fluide utilisé peut être par exemple un liquide tel que de la bière ou de l'eau, ou une pâte ou un produit pâteux tel qu'une sauce ou un condiment alimentaire. Le fluide peut également être tout autre type de fluide par exemple dans le domaine cosmétique, pharmaceutique, phytosanitaire ou chimique. Le contenant selon la présente invention est configuré pour être introduit aisément dans un fût. According to the present invention, the fluid used may be for example a liquid such as beer or water, or a dough or a pasty product such as a sauce or a food condiment. The fluid may also be any other type of fluid, for example in the cosmetic, pharmaceutical, phytosanitary or chemical field. The container according to the present invention is configured to be easily introduced into a drum.
Le contenant selon la présente invention comporte une poche souple destinée à contenir un tel fluide et présentant une ouverture sur sa partie supérieure, cette ouverture étant apte à permettre l'introduction dans la poche d'un plongeur longiligne de remplissage et/ou de vidange.  The container according to the present invention comprises a flexible bag intended to contain such a fluid and having an opening on its upper part, this opening being adapted to allow the introduction into the pocket of a long-necked plunger filling and / or emptying.
Contrairement au réservoir selon le document FR 2 756 470, la poche selon la présente invention n'est pas dans un matériau élastiquement déformable tel qu'un élastomère.  Unlike the tank according to the document FR 2 756 470, the bag according to the present invention is not in an elastically deformable material such as an elastomer.
Le contenant selon la présente invention comporte également une embase fixée à l'intérieur de la poche au niveau de l'ouverture, et apte à permettre le maintien du plongeur dans l'ouverture.  The container according to the present invention also comprises a base fixed inside the pocket at the opening, and adapted to allow the retention of the plunger in the opening.
Le contenant selon la présente invention comporte en outre une contre- embase fixée à l'intérieur de la poche au niveau de sa partie inférieure, et apte à être assemblée de façon temporaire avec l'embase.  The container according to the present invention further comprises a counter-base fixed inside the pocket at its lower part, and able to be assembled temporarily with the base.
Ainsi, grâce à cet assemblage entre la base et la contre-embase, le contenant selon la présente invention est apte à se conformer dans une première configuration, dite de repos, dans laquelle la poche est sensiblement vide de fluide.  Thus, thanks to this assembly between the base and the counter-base, the container according to the present invention is able to comply in a first configuration, said rest, in which the pocket is substantially empty of fluid.
Avantageusement, le contenant dans cette configuration au repos est peu encombrant.  Advantageously, the container in this configuration at rest is compact.
Lorsqu'on introduit un plongeur dans la poche à travers son ouverture, la contre-embase forme un élément d'appui pour l'extrémité d'un plongeur introduit dans la poche à travers l'ouverture, et l'embase coulisse le long dudit plongeur.  When a plunger is introduced into the pocket through its opening, the counter-base forms a support element for the end of a plunger inserted into the pocket through the opening, and the base slides along said diver.
Ainsi, lorsqu'on introduit un tel plongeur dans la poche, et qu'on éloigne la partie supérieure de la partie inférieure de cette poche, l'embase se désassemble de la contre-embase en sorte que le contenant soit conformé selon une deuxième configuration, dite active.  Thus, when such a plunger is introduced into the pocket, and the upper portion of the lower portion of this pocket is moved away, the base disassembles from the counter-base so that the container is shaped according to a second configuration. , called active.
Cette configuration active permet d'une part l'introduction du contenant dans un fût présentant une ouverture ; cette configuration active permet d'autre part un remplissage et/ou une vidange progressi(f)(ve)(s) et uniforme de ia poche. Comme évoqué ci-dessus, la contre-embase forme un élément d'appui du plongeur. Ainsi, lorsqu'on introduit un plongeur dans la poche, la poche ne se déchire pas. This active configuration allows on the one hand the introduction of the container into a drum having an opening; this active configuration also allows a filling and / or emptying progressi (f) (ve) (s) and uniform pocket. As mentioned above, the counter-base forms a support element of the plunger. Thus, when a plunger is introduced into the pocket, the pocket does not tear.
De façon générale, l'agencement selon la présente invention permet d'éviter le déchirement de la poche et/ou que des pressions additionnelles soient exercées sur les parois de la poche et/ou au niveau de la fixation de la poche avec l'embase et/ou la contre-embase, lorsqu'on remplit la poche.  In general, the arrangement according to the present invention makes it possible to avoid tearing of the pocket and / or that additional pressures are exerted on the walls of the pocket and / or at the level of the fixing of the pocket with the base and / or counter-base, when filling the pocket.
Ainsi, selon la présente invention, l'embase et la contre-embase sont adaptées pour être temporairement assemblées l'une à l'autre afin de permettre de conformer le contenant selon au moins deux configurations, dont : a) une première configuration dite au repos dans laquelle l'embase et la contre-embase sont assemblées l'une à l'autre pour réduire l'encombrement du contenant, et b) une deuxième configuration dite active dans laquelle, lorsqu'on introduit un plongeur longiligne dans la poche à travers l'ouverture en sorte qu'il vienne prendre appui sur la contre-embase, l'embase se désassemble de la contre- embase et l'embase coulisse le long du plongeur ; cette deuxième configuration prend la forme d'un « parapluie » à l'état replié.  Thus, according to the present invention, the base and the counter-base are adapted to be temporarily assembled to each other in order to make it possible to shape the container according to at least two configurations, including: a) a first configuration known as rest in which the base and the counter-base are assembled to each other to reduce the size of the container, and b) a second so-called active configuration in which, when an elongated plunger is introduced into the pocket to through the opening so that it comes to bear on the counter-base, the base disassembles the counter-base and the base slides along the plunger; this second configuration takes the form of an "umbrella" in the folded state.
Le contenant dans cette configuration active permet alors une introduction facile du contenant dans un fût, et permet en outre un remplissage et/ou une vidange progressif(ve)(s) et uniforme(s) de la poche.  The container in this active configuration then allows easy introduction of the container into a drum, and further allows a filling and / or a gradual drain (ve) (s) and uniform (s) of the bag.
Selon un mode de réalisation de la présente invention, l'embase et la contre-embase comportent respectivement un premier et un deuxième moyen d'assemblage temporaire aptes à s'emboîter ou à s'encliqueter l'un dans l'autre.  According to one embodiment of the present invention, the base and the counter-base respectively comprise a first and a second temporary assembly means able to fit or snap into each other.
Selon un autre mode de réalisation de la présente invention, l'embase et la contre-embase comportent respectivement un premier et un deuxième moyen d'assemblage temporaire présentant une jonction en plastique commune qui est détachable ou sécable.  According to another embodiment of the present invention, the base and the counter-base respectively comprise a first and a second temporary assembly means having a common plastic junction which is detachable or breakable.
Avantageusement, l'ouverture de la poche est fixée au centre de la partie supérieure de celle-ci, et la contre-embase est fixée au centre de sa partie inférieure. Ainsi, l'embase et la contre-embase sont centrées et sont en regard l'une vis-à-vis de l'autre. Un tel agencement permet une déformation et un déploiement symétrique de la poche lorsque celle-ci se remplit ou se vide du fluide ; ceci est particulièrement avantageux notamment lorsque le contenant est destiné à une introduction dans un fût de forme symétrique Advantageously, the opening of the pocket is fixed at the center of the upper part thereof, and the counter-base is fixed at the center of its lower part. Thus, the base and the counter-base are centered and are facing one vis-à-vis the other. Such an arrangement allows deformation and symmetrical deployment of the bag when it fills or empties the fluid; this is particularly advantageous especially when the container is intended for introduction into a symmetrically shaped drum
Dans le cas d'un fût asymétrique, l'embase et la contre-embase seront positionnées pour obtenir les mêmes effets par rapport au remplissage et la vidange de la poche que pour un fût symétrique.  In the case of an asymmetric shaft, the base and the counter-base will be positioned to obtain the same effects compared to filling and emptying the pocket as for a symmetrical shaft.
Avantageusement, l'embase et/ou la contre-embase est (sont respectivement) fixée(s) à l'intérieur de la poche par thermosoudage, par thermoscellage ou par collage. De façon contraire, la demanderesse observe que, dans ie document FR 2 756 470, l'embase et la contre-embase sont surmoulées sur l'enveloppe qui est dans un matériau élastiquement déformabie.  Advantageously, the base and / or the counter-base is (are respectively) fixed (s) inside the pocket by heat sealing, heat sealing or gluing. On the contrary, the Applicant observes that, in document FR 2 756 470, the base and the counter-base are overmoulded on the envelope which is in an elastically deformable material.
Avantageusement, l'embase et/ou la contre-embase est (sont) en matière plastique, et, de préférence, est (sont) obtenue(s) par un procédé de moulage par injection.  Advantageously, the base and / or the counter-base is (are) made of plastic, and preferably is (are) obtained (s) by an injection molding process.
Avantageusement, la contre-embase consiste notamment une pièce cylindrique présentant au moins un canal d'écoulement du fluide permettant de faciliter le remplissage et/ou la vidange de celle-ci.  Advantageously, the counter-base consists in particular of a cylindrical piece having at least one fluid flow channel facilitating the filling and / or emptying thereof.
La poche selon la présente invention présente une structure comportant au moins un film plastique.  The pouch according to the present invention has a structure comprising at least one plastic film.
De préférence, chaque film plastique est obtenu par co-laminage, par complexage ou par co-extrusion, et comporte au moins un film plastique intérieur et un film plastique extérieur ; le film plastique peut éventuellement comporter un film plastique intermédiaire pour améliorer l'herméticité de la poche.  Preferably, each plastic film is obtained by co-rolling, by complexing or by co-extrusion, and comprises at least one inner plastic film and one outer plastic film; the plastic film may optionally comprise an intermediate plastic film to improve the hermeticity of the pocket.
Avantageusement, le film plastique extérieur présente des caractéristiques de résistance mécanique aux frottements et le film plastique intérieur est fin, isolant, et présente de préférence des propriétés hygiéniques.  Advantageously, the outer plastic film has characteristics of mechanical resistance to friction and the inner plastic film is thin, insulating, and preferably has hygienic properties.
Avantageusement, le film plastique, et notamment le film plastique intérieur, est adapté pour résister au thermosoudage, au thermoscellage et/ou au collage de l'embase et/ou de la contre-embase avec l'intérieur de la poche.  Advantageously, the plastic film, and in particular the inner plastic film, is adapted to withstand heat sealing, heat sealing and / or bonding of the base and / or counter-base with the inside of the pocket.
Corrélativement, l'objet de la présente invention porte également sur un fût comportant en son intérieur un contenant tel que décrit précédemment. De préférence, le fût selon la présente invention comporte également un plongeur longiligne. Correlatively, the object of the present invention also relates to a barrel having in its interior a container as described above. Preferably, the barrel according to the present invention also comprises an elongated plunger.
Le fût selon la présente invention comprend en outre une ouverture sur sa portion supérieure par laquelle on peut introduire et/ou ressortir ledit contenant lorsque celui-ci est dans sa configuration dite active.  The drum according to the present invention further comprises an opening on its upper portion through which one can introduce and / or remove said container when it is in its so-called active configuration.
De préférence, le fût selon la présente invention comporte en outre une buse fixée au plongeur, et vissée au niveau de l'ouverture du fût. L'utilisation d'une buse permet avantageusement d'éviter i'oxydation des produits à l'intérieur de la poche.  Preferably, the barrel according to the present invention further comprises a nozzle attached to the plunger, and screwed at the opening of the barrel. The use of a nozzle advantageously avoids the oxidation of the products inside the pocket.
Cet agencement permet également de pouvoir extraire le fluide à une pression constante.  This arrangement also makes it possible to extract the fluid at a constant pressure.
Avantageusement, la buse est équipée d'un élément de protection détachable permettant de garantir l'intégrité de la poche.  Advantageously, the nozzle is equipped with a detachable protective element to ensure the integrity of the pocket.
Avantageusement, la buse et/ou le plongeur est (sont) constitué(e)(s) dans un matériau rigide ou semi-rigide te! qu'un acier ou un plastique.  Advantageously, the nozzle and / or the plunger is (are) constituted (s) in a rigid or semi-rigid material te! than steel or plastic.
L'objet de la présente invention présente ainsi de nombreux avantages par rapport à l'état de la technique, et notamment une réduction des coûts de fabrication, une réduction du stockage et de l'encombrement, ainsi que des améliorations conséquentes sur les plans logistiques, sanitaires et environnementaux.  The object of the present invention thus has many advantages over the state of the art, and in particular a reduction in manufacturing costs, a reduction in storage and space, as well as significant improvements in logistics plans. , health and environmental.

Description détaillée d'un mode de réalisation  Detailed description of an embodiment
Un contenant et un fût conformes à un mode de réalisation particulier de la présente invention vont maintenant être décrits en référence conjointement aux figures 1 à 5.  A container and a drum according to a particular embodiment of the present invention will now be described with reference to Figures 1 to 5.
Permettre le conditionnement, le stockage et/ou le transport d'un fluide F tel qu'un liquide est un des objectifs de la présente invention.  Allowing the conditioning, storage and / or transport of a fluid F such as a liquid is one of the objectives of the present invention.
Par fluide, on entend dans toute la présente description tous types de substance qui se déforment continuellement sous l'action d'un effort de cisaillement. Ainsi, par fluide, on entend dans toute la présente description tous types de liquide, de gaz, de poudres ou de pâtes.  Fluid means throughout the present description all types of substance that continuously deform under the action of a shearing force. Thus, by fluid means throughout the present description all types of liquid, gas, powder or pasta.
Dans l'exemple décrit ici, le fluide est un liquide tel que de la bière ou de l'eau. Bien évidemment, on comprendra qu'il peut s'agir de tout autre fluide.  In the example described here, the fluid is a liquid such as beer or water. Of course, it will be understood that it can be any other fluid.
Dans l'exemple décrit ici, l'objet de la présente invention concerne donc un contenant 10 adapté pour contenir de !a bière ou de l'eau, et configuré pour être introduit aisément dans un fût 20 lorsque le contenant 10 est vide.  In the example described here, the object of the present invention therefore relates to a container 10 adapted to contain beer or water, and configured to be easily introduced into a drum 20 when the container 10 is empty.
Dans l'exemple décrit ici, le contenant 10 selon la présente invention comporte une poche souple 1 illustrée en figures 2a et 2b.  In the example described here, the container 10 according to the present invention comprises a flexible bag 1 illustrated in Figures 2a and 2b.
La poche 1 selon la présente invention, destinée à contenir de la bière ou de l'eau F, présente une partie supérieure et une partie inférieure formées respectivement par un film plastique supérieure la et un film plastique inférieur lb. Dans l'exemple décrit ici, les deux films plastiques la et 1b sont thermo- soudés entre eux au niveau de leur contour extérieur ; tous autres modes d'assemblage pouvant être utilisés : thermoscellage, collage ou tout autre mode d'assemblage de deux films plastiques. The bag 1 according to the present invention, intended to contain beer or water F, has an upper part and a lower part respectively formed by an upper plastic film 1a and a lower plastic film 1b. In the example described here, the two plastic films 1a and 1b are heat-welded together at their outer contour; all other methods of assembly that can be used: heat sealing, gluing or any other method of joining two plastic films.
La demanderesse soumet que l'assemblage par thermosoudage des films plastiques la et 1b permet une grande résistance aux chocs.  The Applicant submits that the assembly by heat-sealing plastic films 1a and 1b allows a high impact resistance.
Dans l'exemple décrit ici, chaque film plastique la et 1b présente la forme d'un disque. On comprend bien évidemment que ces films plastiques la et lb pourront présenter d'autres formes, ceci en fonction notamment de la forme du fût 20 dans lequel on cherche à positionner le contenant 10.  In the example described here, each plastic film la and 1b has the shape of a disk. It is of course understood that these plastic films 1a and 1b may have other shapes, this depending in particular on the shape of the barrel 20 in which it is sought to position the container 10.
Dans l'exemple décrit ici, comme illustré en figure 2b, chaque film plastique la et lb est constitué d'un film plastique intérieur fiia, fiib et d'un film plastique extérieur feia/ feib ; l'ensemble formé par les films extérieurs feia, eib et intérieurs fiia, fiib étant obtenu par co-extrusion, par co-!aminage, ou par compiexage. In the example described here, as illustrated in Figure 2b, each plastic film Ia and Ib consists of an inner plastic film fii has IIFB and an outer plastic film fe ia / ib fe; the assembly formed by the outer films fei, eib and interior FIIA, IIFB being obtained by co-extrusion, co! aminage, or compiexage.
De préférence, chacun des deux films plastiques extérieurs fela et feib présente des caractéristiques de résistance mécanique aux frottements, et chacun des deux films plastiques intérieurs fiia et fii est fin, isolant, présente de préférence des propriétés hygiéniques. Preferably, each of the two outer plastic film fe and the FEIB has mechanical strength characteristics to friction, and both inner plastic films has fii and fii is thin, insulating, preferably hygienic properties.
Les films plastiques intérieurs fiia et fii présentent également des bonnes caractéristiques d'étanchéité et évitent notamment le phénomène de « flex- cracking » par micro-glissements entre les films, également connu sous le nom de craquelures par flexion. The inner plastic film has fii and fii also have good sealing characteristics and especially avoid the phenomenon of "flex-cracking" micro-shifts between the films, also known as the flex cracking.
L'agencement des films plastiques extérieurs et inférieurs feia, feib, fiia et fiib permettent également de renforcer la résistance aux chocs du contenant 10. The arrangement of external and lower plastic films fei, fei b FIIA IIFB and also allow to enhance the impact resistance of the container 10.
La poche selon la présente invention est ainsi configurée pour pouvoir contenir et stocker tous types de fluide F dans de bonnes conditions sanitaires tout en conservant les propriétés physiques, chimiques, aromatiques ou encore gustatives du fluide F.  The pouch according to the present invention is thus configured to be able to contain and store all types of fluid F in good sanitary conditions while retaining the physical, chemical, aromatic or taste properties of the fluid F.
Dans le cas de la bière par exemple, la poche 1 est adaptée pour conserver notamment les arômes de la bière ainsi que son caractère pétillant. La poche 1 selon la présente invention comporte en outre sur sa partie supérieure et en son centre une ouverture 4 qui va permettre le remplissage et la vidange de la poche 1, In the case of beer for example, the bag 1 is adapted to retain the particular aromas of beer and its sparkling character. The pocket 1 according to the present invention further comprises on its upper part and in its center an opening 4 which will allow the filling and emptying of the pocket 1,
Le contenant 10 selon la présente invention comporte en outre une embase 2 et une contre-embase 3.  The container 10 according to the present invention further comprises a base 2 and a counter-base 3.
Dans l'exemple décrit ici, et comme illustré en figure 2a ou 3, l'embase 2 est fixée à l'intérieur de la poche 1 au niveau de son ouverture 4, et la contre- embase 3 est fixée à l'intérieur de la poche 1 en son centre au niveau de sa partie inférieure ; la fixation de l'embase 2 et de la contre-embase avec l'intérieur de la poche 1 est obtenue par thermosoudage, par thermoscellage ou encore par collage.  In the example described here, and as illustrated in FIG. 2a or 3, the base 2 is fixed inside the pocket 1 at its opening 4, and the counter base 3 is fixed inside the pocket 1 at its center at its lower part; fixing the base 2 and the counter-base with the inside of the pocket 1 is obtained by heat sealing, heat sealing or gluing.
Par ailleurs, on note que, dans l'exemple décrit ici, l'embase 2 et la contre- embase 3 sont en matière plastique, et sont obtenues par un procédé de moulage par injection ou par usinage.  Furthermore, it is noted that, in the example described here, the base 2 and the counter-base 3 are made of plastic, and are obtained by an injection molding process or by machining.
Comme évoqué précédemment, un des objectifs de la présente invention consiste à proposer un contenant 10 dont le remplissage et la vidange du fluide F se fait indifféremment par le haut ou par le bas, et est exécuté de façon progressive et uniforme.  As mentioned above, one of the objectives of the present invention is to provide a container 10, the filling and emptying of the fluid F is indifferently from above or below, and is performed gradually and uniformly.
De plus, le contenant 10 selon la présente invention est simple de fabrication, présente un coût de fabrication peu élevé, et tient compte notamment des problématiques de stockage et des problématiques environnementales.  In addition, the container 10 according to the present invention is simple to manufacture, has a low manufacturing cost, and takes into account in particular storage issues and environmental issues.
Par ailleurs, un des objectifs de la présente invention est également la possibilité d'introduire aisément un tel contenant 10 dans un fût 20 présentant une ouverture O sur sa portion supérieure.  Furthermore, one of the objectives of the present invention is also the possibility of easily introducing such a container 10 into a barrel 20 having an opening O on its upper portion.
L'embase 2 et la contre-embase 3 selon la présente invention sont caractéristiques de la présente invention, et permettent d'atteindre ces différents objectifs.  The base 2 and the counter-base 3 according to the present invention are characteristic of the present invention, and allow to achieve these different objectives.
Comme illustré sur les figures la et 1b, l'embase 2 et la contre-embase 3 sont adaptées pour être assemblées temporairement i'une à l'autre.  As illustrated in Figures 1a and 1b, the base 2 and the counter-base 3 are adapted to be temporarily assembled to one another.
Dans une première variante de réalisation, l'embase 2 et la contre-embase In a first embodiment, the base 2 and the counter-base
3 comportent respectivement un premier 5 et un deuxième 6 moyen d'assemblage temporaire aptes à coopérer ensemble en sorte que l'embase 2 et la contre- embase 3 s'assemblent par emboîtage ou par encliquetage. 3 comprise respectively a first 5 and a second 6 assembly means temporary able to cooperate together so that the base 2 and the counter-base 3 are assembled by casing or snap.
Dans une deuxième variante de réalisation (illustré en figure lb), l'embase 2 et la contre-embase 3 comportent respectivement un premier 5 et un deuxième 6 moyen d'assemblage temporaire présentant une jonction en plastique 8 commune qui est détachable ou sécable.  In a second variant embodiment (illustrated in FIG. 1b), the base 2 and the counter-base 3 respectively comprise a first 5 and a second 6 temporary assembly means having a common plastic junction 8 which is detachable or breakable.
Ainsi, comme illustré en figure lb, l'embase 2 et la contre-embase 3 sont assemblées l'une avec l'autre, et, comme illustré en figure la, l'embase 2 et la contre-embase 3 peuvent se désassembler.  Thus, as illustrated in FIG. 1b, the base 2 and the counter-base 3 are assembled with each other, and, as illustrated in FIG. 1a, the base 2 and the counter-base 3 can disassemble.
L'embase 2 et la contre-embase 3 sont ainsi agencées pour permettre de conformer le contenant 10 seion au moins deux configurations Cl et C2 caractéristiques de la présente invention,  The base 2 and the counter-base 3 are thus arranged to make it possible to form the container 10 with at least two configurations C1 and C2 characteristic of the present invention,
Comme illustré en figure 3, la première configuration Cl, dite au repos, permet d'avoir un contenant 10 vide qui est peu encombrant ; ce qui n'est pas le cas, par exemple, dans l'état de la technique tel que représenté par l'enseignement du document EP 1 736 421,  As illustrated in FIG. 3, the first configuration C1, said to be at rest, makes it possible to have a vacuum container which is not bulky; which is not the case, for example, in the state of the art as represented by the teaching of EP 1 736 421,
Une telle configuration au repos Ci illustrée en figure 3 représente un gain de place appréciable notamment sur le plan logistique.  Such an idle configuration Ci illustrated in FIG. 3 represents an appreciable saving of space, in particular logistically.
La demanderesse observe en outre que l'organe mécanique dans le document FR 2 756 470 placé dans l'enveloppe implique une certaine épaisseur du réservoir, même lorsque celui-ci est vide. La présente invention permet de résoudre ce problème d'encombrement.  The Applicant further observes that the mechanical member in the document FR 2 756 470 placed in the envelope implies a certain thickness of the reservoir, even when it is empty. The present invention solves this congestion problem.
Comme illustré aux figures 4a, 4b et 4c, la deuxième configuration C2, dite active, consiste en ce que, lorsqu'on introduit un plongeur P longiligne dans ia poche 1 à travers l'ouverture 4 et qu'on éloigne la partie supérieure de la partie inférieure, l'extrémité par laquelle on introduit le plongeur P vient prendre appui sur la contre-embase 3, puis l'embase 2 se désassemble de la contre-embase 3.  As illustrated in FIGS. 4a, 4b and 4c, the second configuration C2, called the active one, consists in that, when a long plunger P is introduced into the pocket 1 through the opening 4 and the upper part of the the lower part, the end by which the plunger P is inserted bears on the counter-base 3, then the base 2 disassembles the counter-base 3.
Dans l'exemple décrit ici, l'introduction du plongeur P à travers l'ouverture de la poche entraîne la rupture de l'assemblage entre les premier 5 et deuxième 6 moyens d'assemblage temporaire.  In the example described here, the introduction of the plunger P through the opening of the pocket causes the rupture of the assembly between the first 5 and second 6 temporary assembly means.
De plus, la contre-embase 3 empêche une rupture de la poche 1 si l'introduction du plongeur P est trop brutale. Une telie configuration active illustrée 4b ou 4c permet l'introduction aisée d'un contenant 10 dans un fût 20 ; cette configuration permet en outre le retrait du contenant 10 dudit fût lorsque celui-ci est vidé de son fluide F. La demanderesse observe qu'une telle introduction n'est pas possible avec un réservoir tel que décrit dans le document FR 2 756 470. In addition, the counter-base 3 prevents a rupture of the pocket 1 if the introduction of the plunger P is too abrupt. Such an active configuration illustrated 4b or 4c allows the easy introduction of a container 10 into a drum 20; this configuration also allows the container 10 to be withdrawn from said drum when it is emptied of its fluid F. The Applicant observes that such an introduction is not possible with a reservoir as described in the document FR 2 756 470.
On peut également envisager le cas dans lequel ia poche 1 est constituée dans un matériau très résistant. Dans ce cas, la contre-embase 3 peut éventuellement être optionnelle, et le plongeur P peut prendre appui directement sur la poche 1.  We can also consider the case in which the pocket 1 is made of a very strong material. In this case, the counter-base 3 may optionally be optional, and the plunger P can bear directly on the pocket 1.
Toujours dans ce cas, la contre-embase 3 pourra être remplacé par une pièce rigide ou semi-rigide positionnée à l'extérieure de (a poche, mais présentant les mêmes avantages que la contre-embase 3 (voir ci-dessous).  Still in this case, the counter-base 3 may be replaced by a rigid or semi-rigid piece positioned outside the pocket (but with the same advantages as the counter-base 3 (see below).
La contre-embase 3 contribue à la déformation et au déploiement symétrique de la poche 1 lorsque celle-ci se remplit ou se vide du fluide F.  The counter-base 3 contributes to the deformation and the symmetrical deployment of the bag 1 when it fills or empties the fluid F.
De plus, la contre-embase 3 consolide l'ensemble de la structure du contenant 1, notamment lorsque celui-ci se remplit du fluide F.  In addition, the counter-base 3 consolidates the entire structure of the container 1, especially when it fills with fluid F.
On remarque notamment que la contre-embase 3 évite la rupture de la fixation entre l'embase 2 et la poche 1.  Note in particular that the counter-base 3 avoids the rupture of the binding between the base 2 and the pocket 1.
L'agencement de la contre-embase 3 avec la poche 1 permet donc un remplissage fiable, progressif et uniforme du contenant 1.  The arrangement of the counter-base 3 with the pocket 1 thus allows a reliable, progressive and uniform filling of the container 1.
En tout état de cause, une fois i'embase 2 désassemblée de la contre- embase 3, celle-ci 2 est apte à coulisser le long du plongeur P pour conformer le contenant 10 dans la configuration active C2.  In any event, once the disassembled base 2 of the counter-base 3, the latter 2 is slidable along the plunger P to form the container 10 in the active configuration C2.
Dans le mode de réalisation décrit ici, et comme illustré en figure 4a, lorsqu'on introduit le plongeur P dans le contenant 10 initialement dans sa configuration au repos Cl, l'embase 2 et la contre-embase 3 se désassemblent, et la poche 1 prend naturellement la forme d'un « tutu » centré à mi-hauteur du plongeur P.  In the embodiment described here, and as illustrated in FIG. 4a, when the plunger P is introduced into the container 10 initially in its idle configuration C1, the base 2 and the counter-base 3 disassemble, and the pocket 1 naturally takes the form of a "tutu" centered halfway up the plunger P.
Comme illustré aux figures 4b et 4c, il suffit de rabattre ce « tutu » vers le bas ou vers le haut en fonction du résultat qu'on cherche à obtenir : configuration de « parapluie » tourné vers le bas ou de « parapluie » tourné vers le haut. Bien évidemment, il est également possible de rabattre ce « tutu » à la fois partiellement vers le haut, puis partiellement vers le bas. As illustrated in Figures 4b and 4c, simply fold down this "tutu" down or up depending on the result you want to get: configuration of "umbrella" turned down or "umbrella" turned towards the top. Of course, it is also possible to fold this "tutu" both partially upwards, then partially down.
De cette façon, dans cette configuration active C2 avec une forme en « parapluie » tourné vers le bas et/ou vers le haut, le contenant 10 peut d'une part être aisément introduit dans un fût 20 comme illustré en figure 5a, et peut, d'autre part, permettre un remplissage progressif et uniforme du fluide F par ie haut de la poche 1 comme illustré en figure 5b.  In this way, in this active configuration C2 with an "umbrella" shape turned downwards and / or upwards, the container 10 can be easily introduced into a drum 20 as illustrated in FIG. 5a, and can on the other hand, allow a gradual and uniform filling of the fluid F by the top of the bag 1 as illustrated in Figure 5b.
Pour obtenir un contenant 10 compact et favoriser son introduction dans un fût 20, il est possible d'optimiser le volume occupé par le contenant 10 dans cette configuration active C2 en procédant à une désaération au moins partielle à l'intérieur de la poche 1, une telle désaération étant possible par i'intermédiaire d'une buse B.  To obtain a compact container 10 and facilitate its introduction into a drum 20, it is possible to optimize the volume occupied by the container 10 in this active configuration C2 by performing at least partial deaeration inside the bag 1, such deaeration is possible through a nozzle B.
Dans l'exemple décrit ici, et comme illustré en figure la, la contre-embase 3 consiste notamment une pièce cylindrique présentant des moyens d'écoulement 7 permettant de faciliter le remplissage et/ou la vidange du fluide F, notamment lorsque une des extrémités du plongeur P prend appui sur celle-ci dans la configuration active C2.  In the example described here, and as illustrated in FIG. 1a, the counter-base 3 consists in particular of a cylindrical piece having flow means 7 making it possible to facilitate the filling and / or the emptying of the fluid F, in particular when one of the ends of the plunger P takes support on it in the active configuration C2.
Plus précisément, sur la pian structurel, et dans l'exemple décrit ici en figures la et lb, la contre-embase 3 comporte une partie basse en forme de disque présentant une surface d'appui, et une partie haute à forme d'ensemble sensiblement cylindrique avec au moins trois ailes s'étendant le long de l'axe du cylindre et formant les canaux d'écoulements 7 entre chaque ailes.  More precisely, on the structural yoke, and in the example described here in FIGS. 1a and 1b, the counter-base 3 comprises a low part in the form of a disc having a bearing surface, and an upper part in overall shape. substantially cylindrical with at least three wings extending along the axis of the cylinder and forming the flow channels 7 between each wing.
Ainsi, selon la présente invention, un opérateur en possession d'un tel contenant 10 dispose d'un moyen pratique, économique et facile pour contenir un fluide F.  Thus, according to the present invention, an operator in possession of such a container 10 has a convenient, economical and easy way to contain a fluid F.
On comprend que l'objet de la présente invention peut être livré soit directement pré-assemblé avec un plongeur P. Dans ce cas, l'objet de la présente invention est livré sous la forme d'un contenant 10 tel que décrit ci-dessus avec un plongeur P déjà introduit dans celui-ci : le contenant 10 sera livré dans sa configuration active C2 avec un plongeur P (illustré figures 4b et 4c). L'objet de la présente invention pourra également être livré sous la forme d'un contenant 10 seul : le contenant 10 sera livré dans sa configuration au repos Cl (illustré figure 3). It is understood that the object of the present invention can be delivered either directly pre-assembled with a plunger P. In this case, the object of the present invention is delivered in the form of a container 10 as described above. with a plunger P already introduced into it: the container 10 will be delivered in its active configuration C2 with a plunger P (illustrated in FIGS. 4b and 4c). The object of the present invention may also be delivered in the form of a container 10 alone: the container 10 will be delivered in its idle configuration C1 (illustrated in FIG. 3).
Dans ce cas, en possession d'un tel contenant 10, il suffit à un opérateur d'introduire un plongeur P dans l'ouverture 4 du contenant 10 pour conformer ce dernier dans la configuration active C2.  In this case, in possession of such a container 10, it is sufficient for an operator to introduce a plunger P into the opening 4 of the container 10 to form the latter in the active configuration C2.
Dans l'exemple décrit ici, et comme illustré en figure 5a, le plongeur P comprend en son extrémité supérieure une buse B ; une telle buse B permettant d'exploiter, de façon séparée, le flux d'air et le fluide nécessaires au remplissage et/ou à la vidange du contenant 10.  In the example described here, and as illustrated in FIG. 5a, the plunger P comprises at its upper end a nozzle B; such a nozzle B to operate, separately, the flow of air and fluid necessary for filling and / or emptying the container 10.
Dans l'exemple décrit ici, la buse B comprend un premier élément de protection G consistant par exemple en une goupille détachable ; ce premier élément de protection G permettant d'assurer l'intégrité du contenu du contenant 10.  In the example described here, the nozzle B comprises a first protective element G consisting for example of a detachable pin; this first protection element G to ensure the integrity of the contents of the container 10.
Un deuxième élément de protection peut également être positionné au niveau de i'embase 2 (non illustrée ici) pour permettre d'assurer l'intégrité du contenant de la poche 1 avant remplissage, ou après remplissage si on positionne ce deuxième élément de protection après remplissage.  A second protection element may also be positioned at the base 2 (not shown here) to ensure the integrity of the container of the bag 1 before filling, or after filling if positioning the second protection element after filling.
Pour un tel contenant 10, le flux d'air permet de gérer en contre-pression le remplissage plus ou moins rapide de la poche 1. Il permet également lors de la vidange d'injecter la pression nécessaire pour pousser le fluide qui est dans la poche 1, ou de laisser passer l'air si le fluide est simplement pompé. Lors du soutirage, le volume de fluide doit être compensé par une intrusion d'air pour laisser sortir le liquide.  For such a container 10, the air flow makes it possible to manage in counter-pressure the more or less rapid filling of the bag 1. It also allows, during the emptying, to inject the pressure necessary to push the fluid which is in the pocket 1, or let air through if the fluid is simply pumped. When racking, the volume of fluid must be compensated by an intrusion of air to let out the liquid.
Ensuite, conformément à la figure 5a, il lui suffit d'introduire le contenant Then, according to Figure 5a, it is sufficient to introduce the container
10 dans cette configuration active C2 à travers l'ouverture O du fût 20. 10 in this active configuration C2 through the opening O of the barrel 20.
En effet, grâce aux différentes caractéristiques décrites ci-dessus, le contenant 10 selon la présente invention est particulièrement apte à être introduit aisément dans un fût 20.  Indeed, thanks to the different characteristics described above, the container 10 according to the present invention is particularly suitable for being easily introduced into a drum 20.
Par fût, on entend dans ia présente description tous types de récipient rigide ou semi rigide pouvant contenir un contenant 10 tel que décrit précédemment II peut donc s'agir d'un récipient, d'un fût, d'un baril, d'un bidon, d'un « keg », d'un tonneau ou de tous autres dispositifs de stockage à cet effet. By barrel, in the present description is meant any type of rigid or semi-rigid container that can contain a container 10 as described Previously it can be a container, a barrel, a barrel, a can, a "keg", a barrel or any other storage device for this purpose.
De préférence, le fût 20 selon la présente invention est un fût supérieur ou égal à 20 litres, dont le diamètre est inférieur à 90% de sa hauteur.  Preferably, the barrel 20 according to the present invention is a barrel greater than or equal to 20 liters, the diameter of which is less than 90% of its height.
Dans cet exemple, le fût 20 présente une ouverture 0 qui est étroite, et qui est comprise entre de l'ordre de 60 à 90 millimètres, de préférence égale à de l'ordre 75 millimètres.  In this example, the barrel 20 has an opening 0 which is narrow, and which is between about 60 to 90 millimeters, preferably equal to about 75 millimeters.
Une fois introduit dans le fût 20, dans l'exemple décrit ici, la buse B est vissée au niveau de l'ouverture O dudit fût 20.  Once introduced into the barrel 20, in the example described here, the nozzle B is screwed at the opening O of said barrel 20.
Une fois vissée, il est très facile pour cet opérateur de procéder au remplissage du contenant 10 par le fluide F grâce notamment à la buse B (voir notamment figure 5b).  Once screwed, it is very easy for this operator to fill the container 10 with the fluid F thanks in particular to the nozzle B (see in particular Figure 5b).
Les performances en termes de vidange de la poche 1 obtenues avec un tel contenant 10 sont particulièrement avantageuses dans la mesure où le taux résiduel du fluide est de 1 pour 1000, voire de 1 pour 10 000, ce qui représente de très bonnes performances en termes de conditionnement et de rendement pour un contenant.  The performance in terms of emptying the bag 1 obtained with such a container 10 is particularly advantageous insofar as the residual rate of the fluid is 1 per 1000, or even 1 per 10,000, which represents very good performance in terms of conditioning and yield for a container.
Ainsi, le contenant 10 et le fût 20 selon la présente invention, grâce notamment à l'agencement d'une embase 2 et d'une contre-embase 3, permettent un conditionnement pratique, peu coûteux, et écologique d'un fluide F.  Thus, the container 10 and the barrel 20 according to the present invention, thanks in particular to the arrangement of a base 2 and a counter-base 3, allow a convenient, inexpensive and environmentally friendly packaging of a fluid F.
Il permet en outre le remplacement des barils jetables lourds utilisés notamment dans la chimie.  It also allows the replacement of heavy disposable barrels used in particular in chemistry.
Il devra être observé que cette description détaillée porte sur un mode de réalisation particulier de la présente invention, mais qu'en aucun cas cette description ne revêt un quelconque caractère limitatif à l'objet de l'invention ; bien au contraire, elle a pour objectif d'ôter toute éventuelle imprécision ou toute mauvaise interprétation des revendications qui suivent.  It should be observed that this detailed description relates to a particular embodiment of the present invention, but in no case this description is of any nature limiting to the subject of the invention; on the contrary, its purpose is to remove any imprecision or misinterpretation of the claims that follow.
