Definitions
- the invention relates to a bag for the sealed package of components, and a method of packaging components with said bag.
- the invention applies in particular to the packaging of components transferred from a confined and controlled area such as a clean room or an insulator. These components may be sterile and / or contaminants.
- the activity in confined areas such as insulators or clean rooms requires mastering the entrances and exits of components of these areas, without loss of confinement, to avoid contact between the controlled atmosphere of the confined area and the atmosphere exterior.
- This package is typically a flexible bag of significant length, whose mouth is positioned in communication with the interior of the enclosure.
- the flexible bag and the enclosure are advantageously provided with a junction system such as that described in the document WO 2011/023906 .
- Other possible joining systems are described for example in the documents WO 2010/145042 , FR 2,721,289 and EP 2 091 051 .
- components C can be transferred from inside the enclosure to the interior of the bag. Then the pouch is typically heat sealed, as illustrated on the figure 1b , to isolate the components in a closed compartment and detach this compartment from the rest of the bag.
- the bag In order to store the unused length of the bag ergonomically while facilitating its handling, the bag is typically mounted on a rigid tube T.
- the assembly is mostly done manually by gradually fitting the entire length of the bag on the tube. This is a work requiring a significant time and may also cause problems cleaning and sterilization of the tube between the establishment of two successive bags.
- the bag is delivered already pre-mounted on a rigid tube, this tube is generally located inside the fold zone, which requires to throw the tube from the confined area after the bag has been completely used.
- the object of the invention is to propose a system for packaging components from a confined enclosure that does not have the drawbacks of the prior art.
- an object of the invention is to provide a packaging system less cumbersome than the prior art, and not posing a problem of cleaning or sterilization.
- Another object of the invention is to provide a packaging system generating less waste than pouches mounted on tubes ready for use.
- the closure of the compartment is implemented by heat sealing the wall.
- the folds of the bag are detachably connected with at least one other fold, thereby keeping the folds of the bag together and keeping it compact.
- the bag can be unfolded fold by fold thanks to this detachable connection, to be able to deploy an additional band of the flexible body and thus obtain a new volume that can be filled with components, without the need for a rigid structure to support it.
- the entire length of the bag can be gradually used to package components, which reduces the amount of waste generated by the use of such a bag.
- FIG. 9a With reference to the figure 2 there is shown a bag 1 for packaging components from a confined area.
- the confined area represented in Figures 9a to 9d is an enclosure 2 comprising an internal volume 20 whose atmosphere must not communicate with the atmosphere outside the enclosure.
- the confined area may be an insulator, a clean room, etc.
- the bag 1 comprises a flexible body 10, typically made of a plastic material such as polyethylene, or polyurethane.
- the flexible body comprises a mouth or opening of communication 12, and a side wall 13, also flexible.
- the side wall 13 is closed at a bottom 11.
- the volume defined by the flexible body 10, extending between the bottom and the communication opening 12 is an internal volume of the bag.
- the bag 1 also comprises a junction device 14 with the enclosure 2.
- the junction device 14 advantageously comprises a rigid frame 140 mounted around the communication opening 12, and a door 141 closing the frame 140, the door 141 being movable relative to the frame to selectively close or release the communication opening, thereby allowing the passage of component to the interior of the bag.
- the junction device 14 may comprise a sheath (not shown) connecting the rigid frame 140 to the flexible body 10.
- the chamber 2 similarly comprises a frame 21 and a door 22 movable relative to the frame 21 to selectively open or close access to the internal volume of the enclosure 20.
- the junction device 14 of the bag 1 on the one hand, and the frame 21 and the door 22 of the enclosure of on the other hand are advantageously designed in accordance with WO 2011/023906 (or other similar means already mentioned).
- the opening of the chamber is only performed concomitantly with the opening of the bag, so as to form a a sealed zone formed by the internal volume 20 of the enclosure and that of the bag 1, which eliminates the risk of cross-contamination between the outside atmosphere and the indoor atmosphere.
- the outer surface of the connecting device 14 is in sealing contact with that of the frame 21 and the door, for isolating these surfaces from the atmosphere inside the enclosure 2 and the bag 1.
- the bag 1 typically has a longitudinal major dimension longer than its transverse dimension.
- the excess length in the longitudinal direction is as much potential volume available for the packaging of components as the use of the bag.
- a portion of the side wall 13 disposed between the bottom 11 and the mouth 12 is folded accordion to compactly store this excess length.
- the folding accordion is made by folding strips 130 of the side wall against each other in parallel and alternating folds.
- the strips 130 are all of the same length.
- unfolding a fold always corresponds to the addition of a length identical to the bag 1, corresponding to twice the length of a band 130.
- fold 131 a portion of the side wall formed of two consecutive strips 130 facing each other, and fold line 132 the line of intersection of the two bands.
- a fold 131 is formed of two strips 130 facing one another at their inner face
- a fold 131 ' is formed of two bands facing each other at their outer face.
- the bag 1 comprises a reinforcement of at least one fold, and preferably several or all of the folds, to maintain all the folded strips 130 on each others.
- this reinforcement is achieved by temporarily connecting at least one fold 131 with at least one other fold.
- each fold is connected to at least one other fold.
- each fold may be connected to at least one adjacent fold, or even to the two folds between which it is arranged, where appropriate.
- each fold can also be connected to all other folds.
- At least two consecutive strips 130 may be welded together by a peelable weld 133, i.e. an area where the strips are releasably welded.
- the bag comprises, at the level of at least one fold 131, at least one connector 3 with another fold 131.
- the connector does not pass through a wall of the bag intended to be in contact with the components.
- each fold 131 is connected to at least one other fold, preferably at least one adjacent fold, by a connector 3.
- all the connectors 3 are detachable, that is to say they allow a temporary joining of a fold with the adjacent folds or folds.
- the connectors 3 may be the subject of several embodiments.
- a preferred embodiment of a connector 3 comprises a yoke 30 attached to the outer surface of the fold 131. This embodiment is illustrated in FIGS. Figures 4a to 6 .
- the yoke 30 can be directly integrated in the fold. To do this, one part of each band forming the fold is welded to the part of the other strip lying opposite. This weld is a definitive weld. In this case, the area covered by the yoke 30 remains folded when the ply is detached from the other pleats, which slightly reduces the internal volume of the ply. On the other hand, it eliminates the need to bring additional pieces of material onto the fold.
- the bag 1 comprises a connecting member 31 of each yoke to the yokes of other folds, to maintain all the folds connected together.
- each fold is thus kept connected to the other folds by a structure independent of the other folds, formed by the connecting member 31, which makes it possible to form a fixed point for retaining the other folds when pulling on a fold for the detach from others.
- the connecting member 31 may for example comprise a clamp holding the yokes together by clamping, or a hook extending through the inserts.
- the connecting member 31 comprises a through hole 310 formed in the thickness of each yoke.
- the through hole is arranged only in the thickness of the yoke 30, but not in the wall 13 of the bag to not put in communication the internal volume of the bag with the external atmosphere.
- the orifice is arranged in the welded portion of the fold, so that the orifice passes through the wall 13 on either side, without causing communication between the internal volume of the bag and the outside.
- the connecting member 31 also comprises at least one link 311 whose diameter is smaller than that of the openings of the inserts to be able to pass through the orifices and thus connect several inserts together, at the same time that it is thus connected to each of the inserts.
- connecting members 31 are combinable with the embodiments of the inserts.
- a detachable yoke 30 of the wall 13 of the bag can be implemented in various ways, some of which are illustrated in the drawings. Figures 4a and 4b .
- each yoke 30 may for example be peelably welded to the wall 13, that is to say that it can be detached from the wall by a simple tension exercised on it.
- each yoke 30 may be temporarily attached to the wall 13 by a detachable adhesive tape, or by mechanical means that can be detached by applying traction.
- a detachable adhesive tape or by mechanical means that can be detached by applying traction.
- the means described below with reference to Figures 7a, 7b and 7c can be applied to the attachment of the yoke on the wall 13.
- a yoke 30 has a first connecting member and the wall 13 has a second connection element cooperating with the first element.
- figure 4a an embodiment in which the inserts are removably attached to the wall by a detent device 32
- figure 4b an embodiment in which the inserts are reported removably to the wall by Velvet-hook type strips 32 attached to the wall 13 and the yoke, facing one another.
- the yoke is then preferably permanently affixed to the wall 13 of the bag. This is the case of the yoke formed by welding two parts of strips of a fold, on the figure 5c .
- inserts 30 can be welded (in a non-peelable manner) to the wall of the bag.
- the detachment of a yoke from the connecting means 31 can be the subject of several variants.
- the clamping of the clamp can be adjusted to allow to release a yoke of the clamp by pulling on the wall 13.
- each yoke 30 may comprise one or more cutting lines 303, extending from the edge of the through hole 310 to the edge of the yoke 30
- a cut line is a line of weakness that can open when tension is exerted on both sides of the line. This is for example a line along which micro-perforations are made to form a cutting primer.
- this detachment may be a tear of the yoke or a separation along one (or more) cutting line 303 previously made. This is applicable whether the yoke is reported or integrally formed in the bag.
- a cutting line 303 may be provided between a first portion 301 permanently attached to the wall 13, for example by being welded therein (so as to non-peelable), glued, or fixed by any other means known to those skilled in the art, and a second portion 302 separable from the first.
- a cutting line 303 has also been shown for separating a part 302 from the yoke fastened to the connecting member of a part 301. Since the part 301 is part of the zone of the strips welded together, it closes. the bag even after detachment of the portion 302 and thus retains its seal.
- the yokes of the plies connected to a connecting member and / or interconnected by said member allow to gather the folds of the bag in a compact manner, for example in a pre-established configuration.
- the connectors 3 of a fold 131 are shaped to cooperate with the connectors 3 of an adjacent fold, the connectors being preferably arranged facing one another to cooperate.
- the connectors 3 may be arranged on the inner surface or the outer surface of the strips 130, as long as they do not pass through the wall 13 of the bag, so as not to compromise its tightness.
- This other embodiment can also be the subject of several variants.
- connectors 3 of two adjacent folds form a velvet-hook connection device; a connector 3 comprises a zone 321 covered with loops forming the velvet, and the other connector comprises a zone 322 covered with hooks which hook the loops of the opposite zone 321.
- a connector 3 may comprise a male element 331 and the other connector a female element 332 adapted to removably receive the male element.
- the male element and the female element form a snap button.
- connectors 3 comprise adhesive strips 341 attached to the outer face of the side wall, on two strips 130 in look at each other, the adhesive strips being arranged opposite one another.
- the folds are made on the entire circumference of the side wall 13 so as not to hinder the communication from the chamber 2 to the inside of the bag 1.
- a fold may comprise a single connector 3, or a plurality distributed over the circumference of the side wall.
- each fold 131 comprises a single connector 3.
- each fold 131 comprises several connectors 3, for example two connectors 3.
- the side wall 13 may be formed of two panels 133 comprising lateral edges 134 and transverse edges 135, the panels being joined edge to edge at least by their lateral edges and a transverse edge.
- the other transverse edges may be free to form the communication opening 12 of the bag. Alternatively they can be welded together, and in this case the communication opening 12 can be made in one of the sections.
- the two connectors of a fold are advantageously made on the same pan 133, preferably equidistant from the side edges of the pan.
- the connectors then form two distinct alignments.
- the connecting member 31 may comprise at least a first link 311 passing through orifices of a first alignment of inserts, and at least one second passing through orifices of a second alignment of inserts.
- inserts to be attached to the two panels 133, being arranged on the whole of the circumference of the wall 13.
- the variants of the connectors are of course combinable with the variants concerning their number and their arrangement.
- the bag 1 may further comprise at least one additional attachment means 15 disposed on an outer surface of the side wall 13 of the bag, advantageously facing the communication opening 12.
- This additional fastening means 15 may advantageously take the form of an additional insert permanently attached to the wall, that is to say not peelable.
- This additional yoke comprises at least one protruding portion relative to the side wall, to be hooked to another element.
- this part may comprise a through hole 150 for the passage of a link 4.
- This attachment means makes it possible in particular to grip the wall 13 facing the communication opening to keep it away from the communication opening 12. In fact, in the case where the bag is in communication with the enclosure 2 and that it is subjected to a pressure lower than the atmospheric pressure surrounding the enclosure, this pressure differential can tend to drive the bag into the enclosure.
- a bag 1 is fixed to the door 22 of the enclosure by its junction device 14, and then, on the figure 9b opening the door 22 of the enclosure and the door 141 of the junction device of the bag to put in communication the internal volume of the bag with that of the enclosure.
- An operator can then transfer C components contained in the enclosure to the inside of the bag via open communication between the enclosure and the bag.
- a compartment 16 of the bag is closed, preferably by heat-sealing, to isolate the components in the compartment 16 in a sealed manner.
- the compartment 16 can then be detached from the rest of the bag.
- a new bottom of the bag is formed by closing the wall, for example by heat sealing the wall closing the compartment 16.
- a fold is detached from the other folds to obtain an additional volume of sachet.
- the detached fold is preferably the first fold before the bottom 11 of the bag.
- This fold is unfolded to obtain an additional length of pouch equal to the length of two strips 130. Steps 9c to 9d can be reproduced with new components.

Description
L'invention concerne un sachet pour l'emballage étanche de composants, et un procédé d'emballage de composants avec ledit sachet. L'invention s'applique en particulier à l'emballage de composants transférés à partir d'une zone confinée et contrôlée telle qu'une salle blanche ou un isolateur. Ces composants peuvent être stériles et/ou contaminants.The invention relates to a bag for the sealed package of components, and a method of packaging components with said bag. The invention applies in particular to the packaging of components transferred from a confined and controlled area such as a clean room or an insulator. These components may be sterile and / or contaminants.
L'activité dans des zones confinées telles que des isolateurs ou des salles blanches nécessite de maitriser les entrées et sorties de composants de ces zones, sans perte de confinement, pour éviter tout contact entre l'atmosphère contrôlée de la zone confinée et l'atmosphère extérieure.The activity in confined areas such as insulators or clean rooms requires mastering the entrances and exits of components of these areas, without loss of confinement, to avoid contact between the controlled atmosphere of the confined area and the atmosphere exterior.
En particulier pour la sortie de composants de zones confinées, il est connu, afin de limiter le nombre de manipulations et le coût opérationnel de tels transferts, d'utiliser un emballage unique pour une série de transferts, c'est-à-dire pour faire sortir des composants de l'enceinte à plusieurs reprises.In particular for the output of confined zone components, it is known, in order to limit the number of manipulations and the operational cost of such transfers, to use a single package for a series of transfers, that is to say for remove components from the enclosure several times.
Cet emballage est typiquement un sachet souple d'une longueur importante, dont l'embouchure est positionnée en communication avec l'intérieur de l'enceinte. Pour réaliser cette communication sans risque de perte de confinement ou de contamination de l'atmosphère confinée par l'atmosphère extérieure et réciproquement, le sachet souple et l'enceinte sont avantageusement dotés d'un système de jonction tel que celui décrit dans le document
Comme visible sur la
Sur la
Afin de stocker la longueur non utilisée du sachet de façon ergonomique tout en facilitant sa manipulation, le sachet est typiquement monté sur un tube rigide T. Le montage est la plupart du temps réalisé manuellement en chaussant progressivement toute la longueur du sachet sur le tube. Ceci est un travail nécessitant un temps important et pouvant en outre poser des problèmes de nettoyage et de stérilisation du tube entre les mises en place de deux sachets successifs.In order to store the unused length of the bag ergonomically while facilitating its handling, the bag is typically mounted on a rigid tube T. The assembly is mostly done manually by gradually fitting the entire length of the bag on the tube. This is a work requiring a significant time and may also cause problems cleaning and sterilization of the tube between the establishment of two successive bags.
Dans certains autres cas le sachet est livré déjà pré-monté sur un tube rigide, ce tube est généralement situé à l'intérieur de la zone de plis, ce qui impose de jeter le tube depuis la zone confinée après que le sachet a été complètement utilisé.In some other cases the bag is delivered already pre-mounted on a rigid tube, this tube is generally located inside the fold zone, which requires to throw the tube from the confined area after the bag has been completely used.
En outre, dans tous les cas, un tel tube présente un encombrement important.In addition, in all cases, such a tube has a large footprint.
Des solutions permettant de s'affranchir de l'usage d'un tube rigide ont déjà été proposées, comme par exemple dans le document
Il existe donc un besoin pour un sachet d'emballage peu encombrant, d'utilisation simple et moins contraignant du point de vue ergonomique.There is therefore a need for a packaging bag compact, easy to use and less restrictive from an ergonomic point of view.
L'invention a pour but de proposer un système d'emballage de composants à partir d'une enceinte confinée ne présentant pas les inconvénients de l'art antérieur. En particulier, un but de l'invention est de proposer un système d'emballage moins encombrant que l'art antérieur, et ne posant pas de problématique de nettoyage ou de stérilisation.The object of the invention is to propose a system for packaging components from a confined enclosure that does not have the drawbacks of the prior art. In particular, an object of the invention is to provide a packaging system less cumbersome than the prior art, and not posing a problem of cleaning or sterilization.
Un autre but de l'invention est de proposer un système d'emballage générant moins de déchets que les sachets montés sur des tubes prêts à l'emploi.Another object of the invention is to provide a packaging system generating less waste than pouches mounted on tubes ready for use.
A cet égard, l'invention a pour objet un sachet pour l'emballage étanche de composants, comprenant :
- un corps souple délimitant un volume interne, comprenant :
- ∘ une ouverture de communication, et
- ∘ une paroi latérale comprenant une pluralité de bandes repliées les unes contre les autres, et
- un dispositif de jonction pouvant sélectivement fermer ou libérer l'ouverture de communication, et étant conformé pour être monté sur une enceinte pour permettre une communication étanche entre une cavité interne de l'enceinte et le volume interne du sachet,
- a flexible body delimiting an internal volume, comprising:
- ∘ an opening of communication, and
- A side wall comprising a plurality of folded strips against each other, and
- a connecting device that can selectively close or release the communication opening, and being shaped to be mounted on an enclosure to allow tight communication between an internal cavity of the enclosure and the internal volume of the bag,
Avantageusement, mais facultativement, le sachet selon l'invention peut en outre comprendre au moins l'une des caractéristiques suivantes :
- Au moins une bande d'un pli est connectée de manière détachable à au moins une bande se trouvant en regard par une soudure pelable de ces bandes.

L'invention a également pour objet un procédé d'emballage d'au moins un composant contenu dans une enceinte à environnement contrôlé, comprenant les étapes consistant à :
- amener un sachet selon la description qui précède en communication étanche avec l'enceinte,
- amener au moins un composant de l'intérieur de l'enceinte à l'intérieur du sachet,
- fermer un compartiment du sachet comprenant les composants, et
- détacher le premier pli du sachet avant le fond des autres plis, et déplier ledit pli,
- bring a bag as described above in sealed communication with the enclosure,
- bringing at least one component of the interior of the enclosure into the bag,
- close a compartment of the bag comprising the components, and
- detach the first fold of the bag before the bottom of the other folds, and unfold the said fold,
Avantageusement, mais facultativement, la fermeture du compartiment est mise en oeuvre par thermosoudure de la paroi.Advantageously, but optionally, the closure of the compartment is implemented by heat sealing the wall.
Les plis du sachet sont connectés de manière détachable avec au moins un autre pli, ce qui permet de maintenir ensemble les plis du sachet et de le maintenir compact. De plus le sachet peut être déplié pli par pli grâce à cette connexion détachable, pour pouvoir déployer une bande supplémentaire du corps souple et obtenir ainsi un nouveau volume pouvant être rempli de composants, sans nécessité de structure rigide pour le supporter.The folds of the bag are detachably connected with at least one other fold, thereby keeping the folds of the bag together and keeping it compact. In addition, the bag can be unfolded fold by fold thanks to this detachable connection, to be able to deploy an additional band of the flexible body and thus obtain a new volume that can be filled with components, without the need for a rigid structure to support it.
En outre, toute la longueur du sachet peut ainsi être progressivement utilisée pour emballer des composants, ce qui réduit la quantité de déchets générée par l'utilisation d'un tel sachet.In addition, the entire length of the bag can be gradually used to package components, which reduces the amount of waste generated by the use of such a bag.

Par exemple la zone confinée peut être un isolateur, une salle blanche, etc.For example the confined area may be an insulator, a clean room, etc.
Le sachet 1 comprend un corps souple 10, réalisé typiquement en un matériau plastique tel que du polyéthylène, ou du polyuréthane. Le corps souple comprend une embouchure ou ouverture de communication 12, et une paroi latérale 13, souple également. La paroi latérale 13 est fermée au niveau d'un fond 11. Le volume défini par le corps souple 10, s'étendant entre le fond et l'ouverture de communication 12 est un volume interne du sachet.The
Le sachet 1 comprend également un dispositif de jonction 14 avec l'enceinte 2. Le dispositif de jonction 14 comprend avantageusement un cadre rigide 140 monté autour de l'ouverture de communication 12, et une porte 141 obturant le cadre 140, la porte 141 étant mobile par rapport au cadre pour pouvoir sélectivement fermer ou libérer l'ouverture de communication, en autorisant ainsi le passage de composant vers l'intérieur du sachet.The
De manière optionnelle, le dispositif de jonction 14 peut comprendre une gaine (non représentée) reliant le cadre rigide 140 au corps souple 10.Optionally, the
Avantageusement, l'enceinte 2 comprend de façon analogue un cadre 21 et une porte 22 mobile par rapport au cadre 21 pour sélectivement ouvrir ou fermer un accès au volume interne de l'enceinte 20.Advantageously, the
Afin de ne pas contaminer l'atmosphère du volume interne de l'enceinte avec l'atmosphère extérieure, et réciproquement, le dispositif de jonction 14 du sachet 1 d'une part, et le cadre 21 et la porte 22 de l'enceinte d'autre part, sont avantageusement conçus conformément au document
Le sachet 1 présente typiquement une dimension principale longitudinale plus longue que sa dimension transversale. L'excédent de longueur dans la direction longitudinale constitue autant de volume potentiel disponible pour l'emballage de composants au fur et à mesure de l'usage du sachet.The

Avantageusement, les bandes 130 sont toutes de même longueur. Ainsi le dépliage d'un pli correspond toujours à l'ajout d'une longueur identique au sachet 1, correspondant à deux fois la longueur d'une bande 130.Advantageously, the
Dans la suite on appelle pli 131 une portion de la paroi latérale formée de deux bandes 130 consécutives se trouvant en regard l'une de l'autre, et ligne de pliure 132 la ligne d'intersection des deux bandes.In the following is called fold 131 a portion of the side wall formed of two
On constate, comme visible sur la partie en gros plan de la
En l'occurrence ce qui suit s'applique de la même manière aux deux définitions d'un pli. On conserve donc uniquement la référence 131 pour désigner un pli selon l'une ou l'autre définition. Néanmoins, par souci de cohérence, lorsque plusieurs plis sont désignés pour un même mode de réalisation, la même définition doit être appliquée pour l'ensemble des plis.In this case, the following applies in the same way to both definitions of a fold. We therefore keep only the
Afin de conserver un encombrement limité du sachet, tout en facilitant son utilisation, le sachet 1 comprend un renforcement d'au moins un pli, et de préférence de plusieurs voire de la totalité des plis, pour maintenir toutes les bandes 130 repliées les unes sur les autres.In order to maintain a limited bulk of the bag, while facilitating its use, the
Comme décrit plus en détails ci-après, ce renforcement est réalisé en connectant de manière temporaire au moins un pli 131 avec au moins un autre pli.As described in more detail below, this reinforcement is achieved by temporarily connecting at least one
De préférence, chaque pli est connecté à au moins un autre pli. Par exemple chaque pli peut être connecté au moins à un pli adjacent, voire aux deux plis entre lesquels il est disposé, le cas échéant. Selon un mode de réalisation décrit plus en détails ci-après en référence aux
On va maintenant décrire les différentes variantes de réalisation des connexions possibles.We will now describe the various embodiments of the possible connections.
Selon un premier mode de réalisation, représenté sur les

Sur la
Il est possible de réaliser simultanément une soudure pelable de l'ensemble des plis, auquel cas chaque pli est connecté à l'ensemble des autres plis.It is possible to simultaneously achieve a peelable weld of all the folds, in which case each fold is connected to all other folds.
Selon un deuxième mode de réalisation, représenté sur les
Avantageusement, chaque pli 131 est connecté à au moins un autre pli, de préférence au moins à un pli adjacent, par un connecteur 3.Advantageously, each
Ainsi les plis sont tous maintenus liés les uns aux autres, sans moyen de maintien encombrant à l'extérieur ou à l'intérieur du sachet. De plus, afin de permettre un déploiement progressif du sachet pli par pli, tous les connecteurs 3 sont détachables, c'est-à-dire qu'ils permettent une jonction temporaire d'un pli avec le ou les plis adjacents.Thus the plies are all held together, without bulky holding means on the outside or inside the bag. In addition, in order to allow a progressive deployment of the folded bag by fold, all the
Les connecteurs 3 peuvent faire l'objet de plusieurs modes de réalisation.The
Un mode de réalisation préféré d'un connecteur 3 comporte un empiècement 30 rapporté sur la surface extérieure du pli 131. Ce mode de réalisation est illustré sur les
Alternativement, comme visible sur la
En outre le sachet 1 comprend un organe de liaison 31 de chaque empiècement aux empiècements d'autres plis, pour maintenir tous les plis connectés ensemble. De plus chaque pli est ainsi maintenu connecté aux autres plis par une structure indépendante des autres plis, formée par l'organe de liaison 31, qui permet de former un point fixe de retenue des autres plis lorsque l'on tire sur un pli pour le détacher des autres.In addition the
L'organe de liaison 31 peut par exemple comprendre une pince maintenant les empiècements ensemble par serrage, ou un crochet s'étendant au travers des empiècements.The connecting
Alternativement, et de préférence, l'organe de liaison 31 comprend un orifice traversant 310 réalisé dans l'épaisseur de chaque empiècement. L'orifice traversant n'est agencé que dans l'épaisseur de l'empiècement 30, mais pas dans la paroi 13 du sachet pour ne pas mettre en communication le volume interne du sachet avec l'atmosphère externe. Dans le cas de la
Bien entendu, les variantes d'organes de liaison 31 sont combinables avec les variantes de réalisation des empiècements.Of course, the variants of connecting
Comme décrit plus en détails ci-après, le caractère détachable de la connexion entre deux plis peut être obtenu de plusieurs manières :
- Soit l'empiècement peut être détaché de la paroi 13 du sachet,
- Soit l'empiècement peut être désolidarisé de l'organe de
liaison 31, - Ou encore l'empiècement peut être séparé en une partie fixée à la paroi 13 du sachet, et une partie attachée à l'organe de liaison.
- Either the yoke can be detached from the
wall 13 of the bag, - Either the yoke can be detached from the connecting
member 31, - Or the yoke can be separated into a portion attached to the
wall 13 of the bag, and a portion attached to the connecting member.
En premier lieu, un empiècement détachable 30 de la paroi 13 du sachet peut être mis en oeuvre de différentes manières, dont certaines sont illustrées sur les
Dans le cas où les empiècements 30 sont rapportés sur la paroi 13, chaque empiècement 30 peut par exemple être soudé de manière pelable à la paroi 13, c'est-à-dire qu'il peut être détaché de la paroi par une simple tension exercé sur celui-ci.In the case where the
En variante, chaque empiècement 30 peut être rapporté de façon temporaire à la paroi 13 par une bande adhésive détachable, ou encore par un moyen mécanique pouvant se détacher par application d'une traction. Typiquement, les moyens décrits ci-après en référence aux
On a représenté en
En second lieu, si la connexion détachable est réalisée en séparant un empiècement 30 de l'organe de liaison 31, l'empiècement est alors de préférence fixé de manière définitive à la paroi 13 du sachet. C'est le cas de l'empiècement formé par soudure de deux parties de bandes d'un pli, sur la
Alternativement, dans le cas où les empiècements 30 sont rapportés, ils peuvent être soudés (de manière non pelable) à la paroi du sachet.Alternatively, in the case where the
Le détachement d'un empiècement du moyen de liaison 31 peut faire l'objet de plusieurs variantes.The detachment of a yoke from the connecting means 31 can be the subject of several variants.
Par exemple sur la
Alternativement, sur la
Enfin, en dernier lieu, dans le cas où l'empiècement se détache en une partie 301 fixée à la paroi et une partie 302 fixée à l'organe de liaison, ce détachement peut être une déchirure de l'empiècement ou une séparation le long d'une (ou plusieurs) ligne de découpe 303 préalablement réalisée. Ceci est applicable, que l'empiècement soit rapporté ou formé intégralement dans le sachet.Finally, finally, in the case where the yoke is detached in a
Par exemple, comme représenté sur la
Sur la
Les empiècements des plis reliés à un organe de liaison et/ou reliés entre eux par ledit organe, permettent de réunir les plis du sachet de façon compacte, par exemple dans une configuration pré-établie. Lorsqu'une longueur supplémentaire de sachet est désirée, il suffit de tirer sur le premier pli ou bien sur le fond du sachet 11 pour séparer tout ou partie de l'empiècement correspondant de la paroi 13 et déplier les bandes 130 du pli.The yokes of the plies connected to a connecting member and / or interconnected by said member, allow to gather the folds of the bag in a compact manner, for example in a pre-established configuration. When an additional length of bag is desired, simply pull on the first fold or on the bottom of the
Selon un autre mode de réalisation, les connecteurs 3 d'un pli 131 sont conformés pour coopérer avec les connecteurs 3 d'un pli adjacent, les connecteurs étant de préférence disposés en regard l'un de l'autre pour pouvoir coopérer.According to another embodiment, the
Les connecteurs 3 peuvent être agencés sur la surface intérieure ou la surface extérieure de bandes 130, tant qu'ils ne traversent pas la paroi 13 du sachet, pour ne pas compromettre son étanchéité.The
Cet autre mode de réalisation peut également faire l'objet de plusieurs variantes.This other embodiment can also be the subject of several variants.

Comme visible sur les figures, les plis sont réalisés sur toute la circonférence de la paroi latérale 13 pour ne pas gêner la communication depuis l'enceinte 2 vers l'intérieur du sachet 1.As shown in the figures, the folds are made on the entire circumference of the
Or, un pli peut comprendre un seul connecteur 3, ou une pluralité répartis sur la circonférence de la paroi latérale. Ainsi, selon un mode de réalisation visible par exemple sur la
Ainsi par exemple, la paroi latérale 13 peut être formée de deux pans 133 comprenant des bords latéraux 134 et des bords transversaux 135, les pans étant liés bord à bord au moins par leurs bords latéraux et un bord transversal. Les autres bords transversaux peuvent être libres pour former l'ouverture de communication 12 du sachet. Alternativement ils peuvent être soudés ensemble, et dans ce cas l'ouverture de communication 12 peut être réalisée dans l'un des pans.For example, the
Dans ce cas, les deux connecteurs d'un pli sont avantageusement réalisés sur un même pan 133, avantageusement à égale distance des bords latéraux du pan. Les connecteurs forment alors deux alignements distincts.In this case, the two connectors of a fold are advantageously made on the
Dans ce cas où les connecteurs sont des empiècements 30, l'organe de liaison 31 peut comprendre au moins un premier lien 311 passant par des orifices d'un premier alignement d'empiècements, et au moins un deuxième passant par des orifices d'un deuxième alignement d'empiècements.In this case where the connectors are
En variante on peut encore prévoir que des empiècements soient rapportés sur les deux pans 133, en étant disposés sur l'ensemble de la circonférence de la paroi 13.As a variant, it is also possible for inserts to be attached to the two
Les variantes de réalisation des connecteurs sont bien entendu combinables avec les variantes concernant leur nombre et leur disposition.The variants of the connectors are of course combinable with the variants concerning their number and their arrangement.
Toutes les réalisations proposées ci-avant permettent de rigidifier les plis pour les maintenir en position repliée et/ou de relier les plis les uns aux autres de façon temporaire, et de séparer sélectivement un pli des autres lorsqu'une longueur supplémentaire de sachet est désirée.All the embodiments proposed above make it possible to stiffen the folds to maintain them in the folded position and / or to connect the folds to each other. temporarily, and selectively separate a fold from the others when an additional length of bag is desired.
Enfin, en référence à la
Ce moyen d'attache supplémentaire 15 peut avantageusement prendre la forme d'un empiècement supplémentaire rapporté sur la paroi de manière définitive, c'est-à-dire non pelable. Cet empiècement supplémentaire comprend au moins une partie en saillie par rapport à la paroi latérale, pour pouvoir être accrochée à un autre élément. Optionnellement, cette partie peut comprendre un orifice traversant 150 pour le passage d'un lien 4.This additional fastening means 15 may advantageously take the form of an additional insert permanently attached to the wall, that is to say not peelable. This additional yoke comprises at least one protruding portion relative to the side wall, to be hooked to another element. Optionally, this part may comprise a through
Ce moyen d'attache permet en particulier de saisir la paroi 13 en regard de l'ouverture de communication pour la maintenir éloignée de l'ouverture de communication 12. En effet, dans le cas où le sachet se trouve en communication avec l'enceinte 2 et que celle-ci est soumise à une pression inférieure à la pression atmosphérique entourant l'enceinte, ce différentiel de pression peut tendre à entrainer le sachet vers l'intérieur de l'enceinte.This attachment means makes it possible in particular to grip the

Un opérateur peut ensuite transférer des composants C contenus dans l'enceinte vers l'intérieur du sachet via la communication ouverte entre l'enceinte et le sachet.An operator can then transfer C components contained in the enclosure to the inside of the bag via open communication between the enclosure and the bag.
En
Puis en
Ainsi on a proposé un sachet qui peut être utilisé pour l'emballage successif de plusieurs composants contenus dans une enceinte confinée, tout en conservant un excédent de longueur de stockage plié et maintenu de façon ergonomique et peu encombrante. Le besoin pour une structure de support rigide est supprimé, et partant la quantité de déchets ainsi que les exigences de nettoyage ou de stérilisation entre deux sachets successifs.Thus it has been proposed a bag that can be used for the successive packaging of several components contained in a confined space, while maintaining an excess storage length folded and maintained ergonomically and space-saving. The need for a rigid support structure is eliminated, and thus the amount of waste and the requirements for cleaning or sterilization between two successive bags.
