Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine du transport de produits par un réseau pneumatique de distribution, et porte tout particulièrement sur un sac de transport par réseau pneumatique. De tels sacs de transport sont utilisés pour acheminer des produits depuis au moins un point de départ vers au moins un point d'arrivée, par le biais du réseau pneumatique.The present invention relates to the field of product transport by a pneumatic distribution network, and relates particularly to a pneumatic conveyor bag. Such carrier bags are used to convey products from at least one point of departure to at least one point of arrival, via the pneumatic network.

Une première application concerne le transport de fonds dans des grandes surfaces commerciales, par exemple entre les caisses et un local de collecte des fonds qui sont reliés au moyen d'un réseau pneumatique permettant d'acheminer des sacs contenant des fonds depuis lesdites caisses vers ledit local, de sorte à vider régulièrement ces caisses.A first application relates to the transportation of funds in large commercial areas, for example between the boxes and a fund collection room which are connected by means of a pneumatic network for conveying bags containing funds from said boxes to said local, to regularly empty these boxes.

Une seconde application concerne le transport de prélèvement et de produits médicamenteux en milieu médical, tels que des prélèvements sanguins, des prélèvements de moelle osseuse, des médicaments, des anesthésiants, des vaccins, voire d'autres produits. A titre d'exemple, dans un centre hospitalier, des prélèvements sanguins sont effectués sur les patients dans différents services médicaux puis sont envoyés au laboratoire d'analyse dudit centre, l'acheminement se faisant par un réseau pneumatique. Dans cette application, les prélèvements sont effectués dans des tubes de prélèvement en verre et sont disposés individuellement dans des sachets qui sont eux-mêmes disposés dans un sac de transport, afin de grouper l'acheminement de plusieurs prélèvements jusqu'au laboratoire par le biais du réseau pneumatique.A second application concerns the transport of specimens and medicinal products in a medical environment, such as blood samples, bone marrow samples, medicines, anesthetics, vaccines or even other products. For example, in a hospital center, blood samples are taken from patients in various medical services and then sent to the analysis laboratory of said center, the routing being done by a pneumatic network. In this application, the samples are taken in glass sampling tubes and are individually arranged in bags which are themselves arranged in a transport bag, in order to group the transport of several samples to the laboratory through pneumatic network.

D'autres applications restent envisageables, comme par exemple l'acheminement de produits ou de composants entre le magasin et les unités de production sur un site industriel.Other applications remain possible, such as the routing of products or components between the store and the production units on an industrial site.

Etat de la techniqueState of the art

Sont notamment connus les documents suivants portant sur un sac de transport par réseau pneumatique : EP0664264B1 , EP1757542B1 et FR2869593A1 . Un tel sac comprend deux feuilles assemblées entre elles de manière à définir un contenant délimité par une ouverture permettant l'introduction des produits. La partie d'extrémité de la première feuille constitue un rabat configuré pour être replié afin de coller la face interne de cette première feuille sur la face externe de la seconde feuille, la partie d'extrémité rabattable comprenant sur sa face interne une couche adhésive revêtue provisoirement d'une bande de protection qui est dégagée lors de la fermeture du sac. Au moins l'une des feuilles comprend sur sa face externe au moins une poche dans laquelle peut s'engouffrer l'air pulsé par un système de soufflerie du réseau pneumatique, ce qui permet le déplacement du sac dans ledit réseau.In particular, the following documents relating to a pneumatic conveyor bag are known: EP0664264B1 , EP1757542B1 and FR2869593A1 . Such a bag comprises two sheets assembled together so as to define a container defined by an opening for the introduction of products. The end portion of the first sheet is a flap configured to be folded to bond the inner face of the first sheet to the outer face of the second sheet, the foldable end portion having on its inner face a coated adhesive layer provisionally a protective band that is released when closing the bag. At least one of the sheets comprises on its outer face at least one pocket in which the pulsed air can be rammed by a blower system of the pneumatic network, which allows the displacement of the bag in said network.

Le déplacement du sac de transport dans le réseau pneumatique s'effectue à des vitesses de l'ordre de 8 m/s. Le réseau pneumatique est constitué de conduits qui comprennent de multiples changements de trajectoire. Le sac de transport est donc soumis à d'éventuels chocs dans ces conduits durant son déplacement. Lorsque le sac de transport contient des tubes de prélèvement, il est primordial de garantir la conservation du prélèvement dans ledit sac, au cas où l'un des tubes de prélèvement se briserait et percerait le sachet contenu lui-même dans le sac de transport, comme expliqué ci-dessus, de sorte à éviter tout risque de contamination du réseau pneumatique.The transport bag is moved in the pneumatic network at speeds of the order of 8 m / s. The pneumatic network consists of ducts that include multiple trajectory changes. The transport bag is therefore subject to possible shocks in these ducts during its movement. When the transport bag contains sampling tubes, it is essential to ensure the preservation of the sample in said bag, in the event that one of the sampling tubes breaks and pierces the bag contained itself in the transport bag, as explained above, so as to avoid any risk of contamination of the pneumatic network.

Selon la conception des sacs de transport décrite dans les documents EP0664264B1 , EP1757542B1 et FR2869593A1 l'utilisateur doit rabattre convenablement le rabat pour que la couche adhésive présente sur sa face interne vienne fermer l'ouverture de sorte à assurer une parfaite étanchéité du sac. Cette conception présente pour inconvénient d'exiger la plus grande vigilance de l'utilisateur qui doit mettre en place le rabat avec précaution. En effet, dans le cas où l'utilisateur replie simultanément les deux feuilles du sac pour venir mettre en place et coller la couche adhésive présente sur la face interne du rabat contre la face externe de la seconde feuille, l'ouverture du sac n'est plus fermée de manière étanche. Il y a donc un risque de contamination permanent des réseaux pneumatiques.According to the design of the transport bags described in the documents EP0664264B1 , EP1757542B1 and FR2869593A1 the user must fold the flap suitably so that the adhesive layer has on its inner face comes close the opening so as to ensure a perfect seal of the bag. This design has the disadvantage of requiring the utmost vigilance of the user who must set up the flap carefully. Indeed, in the case where the user simultaneously folds the two sheets of the bag to come up and stick the adhesive layer present on the inner face of the flap against the outer face of the second sheet, the opening of the bag n ' is more tightly closed. There is therefore a risk of permanent contamination of pneumatic networks.

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de pallier cet inconvénient précité en mettant en oeuvre un système de fermeture du sac de transport par réseau pneumatique permettant d'assurer une étanchéité lors de sa mise en place sans compter sur la vigilance de l'utilisateur.The present invention aims to overcome this drawback mentioned above by implementing a closure system of the transport bag by pneumatic network to ensure a seal during its implementation without relying on the vigilance of the user.

A cet effet, l'invention concerne un sac de transport par réseau pneumatique qui comprend deux feuilles assemblées entre elles au moyen d'un cordon de soudure qui s'étend au moins sur les bords latéraux des feuilles de sorte que lesdites feuilles forment un contenant muni d'une ouverture définie entre les bords libres ou séparés desdites feuilles. Lorsque les deux feuilles sont constituées d'une seule pièce pliée en deux, le cordon de soudure est mis en oeuvre uniquement sur les bords latéraux des feuilles. Et lorsque les deux feuilles sont distinctes, le cordon de soudure est mis en oeuvre entre les bords latéraux des feuilles et entre le bord inférieur desdites feuilles définissant le fond du contenant.To this end, the invention relates to a pneumatic conveyor bag which comprises two sheets assembled together by means of a weld seam which extends at least on the lateral edges of the sheets so that said sheets form a container provided with an opening defined between the free or separate edges of said sheets. When the two sheets are made of a single piece folded in two, the weld bead is implemented only on the side edges of the sheets. And when the two sheets are distinct, the weld bead is implemented between the lateral edges of the sheets and between the lower edge of said sheets defining the bottom of the container.

Selon l'invention, le sac de transport comprend également au moins une poche configurée sur la face externe d'au moins une des feuilles pour permettre à un souffle d'air de s'y engouffrer. L'orientation de la poche définit le sens de déplacement du sac de transport dans un réseau pneumatique. Comme cela sera précisé ci-après, le sac peut comprendre une seule poche agencée dans un sens ou dans l'autre sur l'une ou l'autre des faces externes des deux feuilles, deux poches agencées sur une même face externe en sens opposés, deux poches agencées respectivement sur les deux faces externes dans un même sens ou en sens opposés, quatre poches dont deux en sens opposés sur chacune des faces externes, voire toutes autres variantes.According to the invention, the carrying bag also comprises at least one pocket configured on the outer face of at least one of the sheets to allow a breath of air to engulf. The orientation of the pocket defines the direction of movement of the transport bag in a pneumatic network. As will be specified below, the bag may comprise a single pocket arranged in one direction or the other on one or the other of the outer faces of the two sheets, two pockets arranged on the same outer face in opposite directions. , two pockets respectively arranged on the two outer faces in the same direction or in opposite directions, four pockets, two in opposite directions on each of the outer faces, or other variants.

En outre, selon l'invention, le sac comprend un système de fermeture qui comporte un cordon adhésif s'étendant latéralement sur la face interne d'une des feuilles au niveau de l'ouverture. Les extrémités latérales du cordon adhésif sont sécantes avec les extrémités latérales respectives du cordon de soudure sur les bords latéraux des feuilles. Ce système de fermeture comporte également une bande de protection amovible qui s'étend latéralement en recouvrant provisoirement la quasi-totalité du cordon adhésif. Par ailleurs, les deux portions latérales du cordon adhésif et les deux portions latérales de la bande de protection sont configurées les unes vis-à-vis des autres pour que les extrémités latérales du cordon adhésif soient dégagées des extrémités de la bande de protection et accessibles de manière à être mises en contact avec les extrémités latérales respectives du cordon de soudure. Cette configuration assure une parfaite étanchéité du sac de transport après sa fermeture, c'est-à-dire après le retrait de la bande de protection et le collage de la face interne de la seconde feuille contre la face interne de la première feuille. La mise en oeuvre du système de fermeture entre les faces internes des deux feuilles évite toute erreur de manipulation du sac de transport lors de sa fermeture, puisqu'il suffit de retirer la bande de protection amovible et de plaquer les deux feuilles l'une contre l'autre. Cette conception permet en outre de supprimer la présence d'un rabat de fermeture.In addition, according to the invention, the bag comprises a closure system which comprises an adhesive bead extending laterally on the internal face of one of the sheets at the opening. The lateral ends of the adhesive bead are intersecting with the respective lateral ends of the bead on the side edges of the sheets. This closure system also comprises a removable protective strip that extends laterally temporarily covering substantially all of the adhesive bead. Furthermore, the two side portions of the adhesive bead and the two lateral portions of the protective strip are configured vis-à-vis each other so that the lateral ends of the adhesive bead are released from the ends of the protective strip and accessible so as to be brought into contact with the respective lateral ends of the weld seam. This configuration ensures a perfect sealing of the transport bag after its closure, that is to say after the withdrawal of the protective strip and the bonding of the inner face of the second sheet against the inner face of the first sheet. The implementation of the closure system between the inner faces of the two sheets avoids any error in handling the transport bag when it is closed, since it suffices to remove the removable protective strip and to press the two sheets against each other. the other. This design also eliminates the presence of a closure flap.

Dans une réalisation non limitative du sac de transport selon l'invention, les extrémités latérales du cordon de soudure comprennent chacune un point de soudure additionnel. Ces points de soudure sont configurés pour déborder sur les extrémités latérales respectives du cordon adhésif. Cela permet de renforcer les jonctions des extrémités latérales du cordon de soudure avec les extrémités latérales du cordon adhésif, pour garantir une parfaite étanchéité du sac de transport après sa fermeture, dans toutes les circonstances d'utilisation.In a non-limiting embodiment of the carrying bag according to the invention, the lateral ends of the weld bead each comprise an additional weld point. These solder points are configured to overflow the respective lateral ends of the adhesive bead. This reinforces the junctions of the lateral ends of the weld bead with the lateral ends of the adhesive bead, to ensure a perfect seal of the transport bag after its closure, under all circumstances of use.

Dans une réalisation non limitative du sac de transport selon l'invention, le cordon adhésif comprend une forme en créneau configurée pour que ses portions latérales soient déportées des portions latérales de la bande de protection. D'autres formes restent envisageables, par exemple une forme arquée ou une forme en zigzag, voire toute autre forme permettant la mise en oeuvre de l'invention.In a non-limiting embodiment of the carrying bag according to the invention, the adhesive bead comprises a slot shape configured so that its side portions are offset from the side portions of the protective strip. Other forms remain possible, for example an arched shape or a zigzag shape, or even any other form for implementing the invention.

Dans une autre réalisation du sac de transport selon l'invention, les portions latérales de la bande de protection comportent des découpes permettant le dégagement des portions latérales du cordon adhésif qui présente de préférence une forme droite.In another embodiment of the carrying bag according to the invention, the lateral portions of the protective strip comprise cutouts allowing the release of the lateral portions of the adhesive bead which preferably has a straight shape.

Dans une réalisation du sac de transport selon l'invention, le système de fermeture comprend une bande adhésive additionnelle qui s'étend latéralement de manière attenante ou avoisinante au cordon adhésif sur la face interne de la feuille. Cette bande adhésive est entièrement revêtue provisoirement par la bande de protection amovible, jusqu'à son retrait. Cette bande adhésive renforce l'assemblage entre les deux feuilles, ce qui évite tout risque d'ouverture du sac lorsque celui-ci est fortement rempli et/ou est fortement sollicité durant son déplacement dans le réseau pneumatique.In one embodiment of the carrier bag according to the invention, the closure system comprises an additional adhesive tape that extends laterally adjacent or adjacent to the adhesive bead on the inner face of the sheet. This adhesive strip is entirely temporarily covered by the removable protective strip until it is removed. This adhesive tape strengthens the assembly between the two sheets, which avoids any risk of opening the bag when it is heavily filled and / or is highly stressed during its movement in the pneumatic network.

Dans une réalisation du sac de transport selon l'invention, celui-ci comprend deux poches agencées respectivement sur les faces externes des deux feuilles. De préférence, ces deux poches sont agencées du côté du fond du contenant ou, au contraire, du côté de l'ouverture du contenant. Ces positions précitées des poches définissent l'orientation du sac de transport durant son déplacement dans le réseau pneumatique. Dans une variante, une poche est agencée du côté du fond du contenant sur la première feuille et une poche est agencée du côté de l'ouverture du contenant sur la seconde feuille, ou inversement, ce qui permet d'orienter le sac de transport dans un sens ou dans l'autre dans le réseau pneumatique, ce qui facilite son utilisation.In one embodiment of the carrying bag according to the invention, it comprises two pockets respectively arranged on the outer faces of the two sheets. Preferably, these two pockets are arranged on the bottom side of the container or, on the contrary, on the side of the opening of the container. These aforementioned positions of the pockets define the orientation of the transport bag during its movement in the pneumatic network. In a variant, a pocket is arranged on the bottom side of the container on the first sheet and a pocket is arranged on the side of the opening of the container on the second sheet, or vice versa, which makes it possible to orient the transport bag in one way or the other in the pneumatic network, which facilitates its use.

Dans une autre réalisation du sac de transport selon l'invention, celui-ci comprend quatre poches. Deux poches sont agencées sur chacune des faces externes des deux feuilles, les deux poches sur chaque face externe étant agencées en opposition. Cela permet d'orienter le sac de transport dans un sens ou dans l'autre dans le réseau pneumatique.In another embodiment of the transport bag according to the invention, it comprises four pockets. Two pockets are arranged on each of the outer faces of the two sheets, the two pockets on each outer face being arranged in opposition. This makes it possible to orient the transport bag in one direction or the other in the pneumatic network.

Dans une réalisation du sac de transport selon l'invention, les deux feuilles et l'au moins une poche sont mises en oeuvre au moyen d'une seule et unique feuille.In one embodiment of the transport bag according to the invention, the two sheets and the at least one pocket are implemented by means of a single sheet.

Dans une réalisation du sac de transport selon l'invention, celui-ci comprend des moyens d'ouverture facile du contenant après la mise en place du système de fermeture. Ces moyens d'ouverture facile permettent de déchirer manuellement le sac de transport pour accéder à son contenu, ce qui évite de devoir manipuler en complément un outil de découpe, notamment une paire de ciseaux ou un couteau, afin de conserver les mains libres et, ainsi, de réduire les risques de faire tomber le sac ouvert ou une partie de son contenu.In one embodiment of the carrying bag according to the invention, it comprises means for easy opening of the container after the establishment of the closure system. These easy opening means make it possible to tear the transport bag manually in order to access its contents, which avoids having to manipulate in addition a cutting tool, in particular a pair of scissors or a knife, in order to keep the hands free and, thus, reduce the risk of dropping the open bag or part of its contents.

Dans une réalisation du sac de transport selon l'invention, celui-ci comprend une partie d'en-tête disposée dans le prolongement d'au moins une des deux feuilles. Des moyens de détachement sont agencés entre la partie d'en-tête et ladite feuille. En outre, dans une variante, la partie d'en-tête comprend des moyens d'accrochage à un support. Cette conception permet de livrer les sacs de transport en liasse et, lorsque des moyens d'accrochage sont prévus, d'accrocher la liasse sur un support, les sacs de transport étant détachés individuellement de la liasse pour être utilisés.In one embodiment of the carrying bag according to the invention, the latter comprises a header portion disposed in the extension of at least one of the two sheets. Detachment means are arranged between the header portion and said sheet. In addition, in a variant, the header portion comprises means for attachment to a support. This design makes it possible to deliver the transport bags in a bundle and, when the attachment means are provided, to hang the bundle on a support, the transport bags being individually detached from the bundle to be used.

Description détailléedetailed description

Dans la suite de la description, les mêmes références sont utilisées pour définir les caractéristiques identiques selon les diverses variantes de réalisation du sac de transport par réseau pneumatique, désigné ci-après sac de transport.In the remainder of the description, the same references are used to define the identical characteristics according to the various variants of the transport bag by pneumatic network, hereinafter referred to as the transport bag.

Tel qu'illustré sur les figures 1 à 8, le sac de transport 1 comprend deux feuilles 2, 3 qui peuvent être distinctes ou, au contraire, constituées d'une seule pièce. Lorsque ces deux feuilles sont distinctes, celles-ci sont assemblées entre elles au moyen d'un cordon de soudure 4 qui s'étend sur les bords latéraux 5, 6 et sur le fond 7, comme illustré en figure 6. Lorsque les deux feuilles 2, 3 sont constituées d'une seule pièce, celle-ci est repliée sur elle-même au niveau du fond 7 et le cordon de soudure 4 s'étend uniquement sur les bords latéraux 5, 6. Les deux feuilles 2, 3 assemblées entre elles forment un contenant 8 avec une ouverture 9 définie entre les bords libres 10, 11 desdites feuilles 2, 3.As illustrated on Figures 1 to 8 , the carrying bag 1 comprises two sheets 2, 3 which may be separate or, conversely, consist of a single piece. When these two sheets are distinct, they are assembled together by means of a weld bead 4 which extends on the lateral edges 5, 6 and on the bottom 7, as illustrated in FIG. figure 6 . When the two sheets 2, 3 consist of a single piece, it is folded on itself at the bottom 7 and the weld bead 4 extends only on the side edges 5, 6. The two sheets 2, 3 assembled together form a container 8 with an opening 9 defined between the free edges 10, 11 of said sheets 2, 3.

Tel qu'illustré sur les figures 1 à 8, le sac de transport 1 comprend un système de fermeture 12. Ce système de fermeture 12 comprend un cordon adhésif 13 qui s'étend latéralement jusqu'aux bords latéraux 5, 6 des feuilles 2,3. Le cordon adhésif 13 est agencé sur la face interne 2a de la première feuille 2. Le cordon adhésif 13 présente une forme en créneau telle qu'illustrée sur les figures 2, 4, 6 et 8, avec une portion centrale 13a et deux portions latérales 13b, 13c. En complément, le système de fermeture 12 comprend une bande adhésive 14 qui s'étend latéralement de manière attenante ou avoisinante à la portion centrale 13a du cordon adhésif 13, comme illustré sur les figures 2, 4, 6 et 8. La bande adhésive 14 est de largeur plus importante que le cordon adhésif 13. On prévoit de préférence un rapport entre quatre et six entre la largeur du cordon adhésif 13 et la bande adhésive 14. Par exemple, le cordon adhésif 13 a une largeur de 1 mm et la bande adhésive 14 a une largeur de 5 mm. On pourrait toutefois prévoir une bande adhésive 14 de largeur plus importante ou plus faible, voire sensiblement identique à la largeur du cordon adhésif 13.As illustrated on Figures 1 to 8 , the carrying bag 1 comprises a closure system 12. This closure system 12 comprises an adhesive bead 13 which extends laterally to the side edges 5, 6 of the sheets 2, 3. The adhesive bead 13 is arranged on the inner face 2a of the first sheet 2. The adhesive bead 13 has a slot shape as illustrated in FIGS. figures 2 , 4 , 6 and 8 , with a central portion 13a and two side portions 13b, 13c. In addition, the closure system 12 comprises an adhesive strip 14 which extends laterally adjacent or adjacent to the central portion 13a of the adhesive bead 13, as illustrated in FIGS. figures 2 , 4 , 6 and 8 . The adhesive strip 14 is of greater width than the adhesive bead 13. Preferably, a ratio of between four and six is provided between the width of the adhesive bead 13 and the adhesive strip 14. For example, the adhesive bead 13 has a width of 1 mm and the adhesive strip 14 has a width of 5 mm. However, there could be an adhesive strip 14 of greater or smaller width, or substantially identical to the width of the adhesive bead 13.

Tel qu'illustré sur les figures 1 à 8, le système de fermeture 12 comprend une bande de protection 15 qui est amovible. Cette bande de protection 15 recouvre provisoirement la quasi-totalité du cordon adhésif 13 et toute la bande adhésive 14. Tel qu'illustré sur les figures 2, 4, 6 et 8, la forme en créneau du cordon adhésif 13 permet de déporter ses extrémités latérales 16, 17 au-delà de la bande de protection 15, de sorte que lesdites extrémités latérales 16, 17 rejoignent les extrémités latérales 18, 19 du cordon de soudure 4, ce qui permet d'assurer une parfaite étanchéité au niveau de l'ouverture 9 du sac de transport 1, lors de la mise en place du système de fermeture 12. On pourrait prévoir d'autres formes qu'une forme en créneau pour le cordon adhésif 13, par exemple une forme arquée ou une forme en zigzag. Pour garantir une parfaite jonction entre le cordon de soudure 4 et le cordon adhésif 13, les extrémités latérales 18, 19 dudit cordon de soudure 4 comprennent des points de soudure 20, 21 additionnels qui s'étendent légèrement sur les extrémités latérales 16, 17 du cordon adhésif 13, tel qu'illustré en figures 2, 4 et 6. La mise en place du système de fermeture 12 s'effectue en dégageant la bande de protection 15, ce qui libère le cordon adhésif 13 et la bande adhésive 14, puis en plaquant la face interne 3a de la seconde feuille 3 contre la face interne 2a de la première feuille 2.As illustrated on Figures 1 to 8 , the closure system 12 comprises a protective strip 15 which is removable. This protective strip 15 temporarily covers almost the entire adhesive bead 13 and all the adhesive strip 14. As illustrated in FIG. figures 2 , 4 , 6 and 8 , the crenel shape of the adhesive bead 13 makes it possible to deport its lateral ends 16, 17 beyond the protective band 15, so that said lateral ends 16, 17 meet the lateral ends 18, 19 of the weld bead 4, which makes it possible to ensure a perfect seal at the opening 9 of the transport bag 1, during the establishment of the closure system 12. It could provide other shapes than a slot form for the cord adhesive 13, for example an arcuate shape or a zigzag shape. To ensure a perfect junction between the weld bead 4 and the adhesive bead 13, the lateral ends 18, 19 of said weld bead 4 comprise additional weld points 20, 21 which extend slightly over the lateral ends 16, 17 of the adhesive cord 13, as illustrated in figures 2 , 4 and 6 . The establishment of the closure system 12 is effected by releasing the protective strip 15, which releases the adhesive bead 13 and the adhesive strip 14, then by plating the inner face 3a of the second sheet 3 against the inner face 2a of the first sheet 2.

Tel qu'illustré sur les figures 1 à 8, la première feuille 2 comprend une partie d'en-tête 22 qui s'étend au-delà de son bord libre 10. Une ligne de prédécoupe 23 permet de détacher la partie d'en-tête 22 du bord libre 10 de la feuille 2. La partie d'en-tête 22 comprend deux orifices 24, 25 qui permettent de suspendre le sac de transport 1 à deux tiges de support (non illustrées). Cela permet avantageusement le conditionnement des sacs de transport 1 sous la forme d'une liasse (non illustrée), les sacs de transport 1 pouvant être détachés successivement de la liasse.As illustrated on Figures 1 to 8 the first sheet 2 comprises a header portion 22 which extends beyond its free edge 10. A pre-cut line 23 detaches the header portion 22 from the free edge 10 of the sheet 2. The header portion 22 includes two orifices 24, 25 which allow the transport bag 1 to be suspended from two support rods (not shown). This advantageously allows the packaging of the transport bags 1 in the form of a bundle (not shown), the transport bags 1 can be detached successively from the bundle.

Tel qu'illustré sur les figures 2, 4, 6 et 8, le sac de transport 1 comprend deux entailles 26, 27 agencées respectivement sur les deux bords latéraux 5, 6 des feuilles 2, 3, en-dessous du système de fermeture 12. Ces entailles 26, 27 permettent d'ouvrir manuellement le contenant 8 après la mise en place du système de fermeture 12.As illustrated on figures 2 , 4 , 6 and 8 , the carrying bag 1 comprises two notches 26, 27 respectively arranged on the two side edges 5, 6 of the sheets 2, 3, below the closure system 12. These notches 26, 27 allow manual opening of the container 8 after installation of the closure system 12.

Sur le mode de réalisation des figures 1 et 2, le sac de transport 1 comprend deux poches 28, 29 agencées respectivement sur les faces externes 2b, 3b des feuilles 2, 3, du côté du fond 7 du contenant 8. L'air soufflé par un système de soufflerie d'un réseau pneumatique (non illustré) peut donc s'engouffrer dans le sens des flèches 30, 31 à l'intérieur des poches 28, 29, comme l'illustre la figure 1.On the embodiment of Figures 1 and 2 , the carrying bag 1 comprises two pockets 28, 29 respectively arranged on the outer faces 2b, 3b of the sheets 2, 3, on the side of the bottom 7 of the container 8. The air blown by a blower system of a pneumatic network (not shown) can thus rush in the direction of the arrows 30, 31 inside the pockets 28, 29, as illustrated by FIG. figure 1 .

Sur le mode de réalisation des figures 3 et 4, le sac de transport 1 comprend deux poches 32, 33 agencées respectivement sur les faces externes 2b, 3b des feuilles 2, 3, du côté de l'ouverture 9 du contenant 8. L'air soufflé par un système de soufflerie d'un réseau pneumatique (non illustré) peut donc s'engouffrer dans le sens des flèches 34, 35 à l'intérieur des poches 28, 29, comme l'illustre la figure 3.On the embodiment of Figures 3 and 4 , the carrying bag 1 comprises two pockets 32, 33 respectively arranged on the outer faces 2b, 3b of the sheets 2, 3, on the side of the opening 9 of the container 8. The air blown by a blower system of a pneumatic network (not shown) can therefore rush in the direction of the arrows 34, 35 inside the pockets 28, 29, as shown in FIG. figure 3 .

Sur le mode de réalisation des figures 5 et 6, le sac de transport 1 comprend quatre poches 36, 37, 38, 39, deux poches 36, 37 étant agencées en opposition sur la face externe 2b de la première feuille 2 et deux poches 38, 39 étant agencées en opposition sur la face externe 3b de la seconde feuille 3. L'air soufflé par un système de soufflerie d'un réseau pneumatique (non illustré) peut donc s'engouffrer soit dans le sens des flèches 40, 41 à l'intérieur des poches 36, 38, soit dans le sens des flèches 42, 43 à l'intérieur des poches 37, 39, comme l'illustre la figure 5.On the embodiment of Figures 5 and 6 , the carrying bag 1 comprises four pockets 36, 37, 38, 39, two pockets 36, 37 being arranged in opposition on the outer face 2b of the first sheet 2 and two pockets 38, 39 being arranged in opposition on the outer face 3b of the second sheet 3. The air blown by a blower system of a pneumatic network (not shown) can thus rush in the direction of the arrows 40, 41 inside the pockets 36, 38, or in the direction of the arrows 42, 43 inside the pockets 37, 39, as the illustrates the figure 5 .

Sur le mode de réalisation des figures 7 et 8, le sac de transport 1 comprend deux poches 44, 45 agencées respectivement sur les faces externes 2b, 3b des feuilles 2, 3. La première poche 44 est disposée du côté du fond 7 du contenant 8 et la seconde poche 45 est disposée du côté de l'ouverture 9 du contenant 8. L'air soufflé par un système de soufflerie d'un réseau pneumatique (non illustré) peut donc s'engouffrer dans le sens de la flèche 46 à l'intérieur de la première poche 44 ou dans le sens de la flèche 47 à l'intérieur de la seconde poche 45, comme l'illustre la figure 7, selon le sens d'orientation du sac 1 dans le réseau pneumatique.On the embodiment of Figures 7 and 8 , the carrying bag 1 comprises two pockets 44, 45 respectively arranged on the outer faces 2b, 3b of the sheets 2, 3. The first pocket 44 is disposed on the side of the bottom 7 of the container 8 and the second pocket 45 is disposed on the side of the opening 9 of the container 8. The air blown by a blower system of a pneumatic network (not shown) can therefore rush in the direction of the arrow 46 inside the first pocket 44 or in the direction of the arrow 47 inside the second pocket 45, as illustrated by figure 7 according to the direction of orientation of the bag 1 in the pneumatic network.

De préférence les feuilles sont réalisées dans une matière polyéthylène transparente, ce qui permet de visualiser les produits contenus dans le sac de transport 1 et de détecter si un tube de prélèvement est cassé, avant l'ouverture du contenant 8.Preferably the sheets are made of a transparent polyethylene material, which makes it possible to visualize the products contained in the transport bag 1 and to detect if a sampling tube is broken, before the opening of the container 8.

La description détaillée qui précède, de variantes de réalisation du sac de transport 1 selon l'invention, n'a aucun caractère limitatif. Bien au contraire, elle a pour objectif d'ôter toute éventuelle imprécision quant à sa portée. Ainsi, de nombreuses variantes pourront être envisagées dans le cadre de l'invention, notamment quant à la conception des poches sur les faces externes 2b, 3b des feuilles 2, 3.The foregoing detailed description of embodiments of the carrying bag 1 according to the invention is not limiting in nature. On the contrary, it aims to remove any imprecision as to its scope. Thus, many variants may be envisaged within the scope of the invention, in particular as regards the design of the pockets on the outer faces 2b, 3b of the sheets 2, 3.

A titre d'exemple, sur la figure 9, le cordon adhésif 13 s'étend en ligne droite sur toute sa largeur jusqu'aux bords latéraux 5, 6 sur la feuille 2. En outre la bande de protection 15 comprend au niveau de ses portions latérales 15a, 15b des découpes 48, 49 qui permettent le dégagement des portions latérales 13b, 13c du cordon adhésif 13, ce qui permet aux extrémités latérales 18, 19 du cordon de soudure 4 de venir en contact avec les extrémités latérales 16, 17 dudit cordon adhésif 13. Il est possible de prévoir deux points de soudure 20, 21 complémentaires au niveau des extrémités latérales 18, 19 dudit cordon de soudure 4.For example, on the figure 9 , the adhesive bead 13 extends in a straight line across its width to the side edges 5, 6 on the sheet 2. In addition, the protective strip 15 comprises at its side portions 15a, 15b cutouts 48, 49 which allow the release of the lateral portions 13b, 13c of the adhesive bead 13, which allows the lateral ends 18, 19 of the weld bead 4 to come into contact with the lateral ends 16, 17 of said adhesive bead 13. It is possible to provide two complementary welding points 20, 21 at the lateral ends 18, 19 of said weld seam 4.

Dans un autre exemple, sur la figure 10, le sac de transport 1 est réalisé au moyen d'une seule et unique feuille repliée plus ou moins en formant un « M », de manière à constituer la première feuille 2 et la seconde feuille 3, ainsi que deux poches 50, 51 disposées respectivement sur les deux feuilles 2, 3 du côté de l'ouverture 9 du contenant 8, après la mise en place du cordon de soudure sur les bords latéraux (non illustré sur la figure 10).In another example, on the figure 10 , the carrying bag 1 is made by means of a single and single sheet folded more or less forming an "M", so as to constitute the first sheet 2 and the second sheet 3, and two bags 50, 51 arranged respectively on the two sheets 2, 3 on the side of the opening 9 of the container 8, after the introduction of the weld seam on the side edges (not shown in FIG. figure 10 ).

De manière comparable, sur la figure 11, le sac de transport 1 est réalisé au moyen d'une seule et unique feuille repliée plus ou moins en formant un « N» de sorte à constituer la première feuille 2 et la seconde feuille 3, ainsi qu'une poche 52 disposée sur l'une des feuilles 2 du côté de l'ouverture 9 du contenant 8, après la mise en place du cordon de soudure sur les bords latéraux (non illustré sur la figure 11).In a comparable way, on the figure 11 , the carrying bag 1 is made by means of a single and only one sheet folded more or less forming an "N" so as to constitute the first sheet 2 and the second sheet 3, and a pocket 52 disposed on the one of the sheets 2 on the side of the opening 9 of the container 8, after the positioning of the weld seam on the lateral edges (not shown on the figure 11 ).

De manière comparable, sur la figure 12, le sac de transport 1 est réalisé au moyen d'une seule et unique feuille repliée plus ou moins en formant un « V » et en rabattant la portion d'extrémité en pointe dudit « V », de sorte à constituer la première feuille 2 et la seconde feuille 3, ainsi qu'une poche 53 disposée sur l'une des feuilles 3 du côté du fond 7 du contenant 8, après la mise en place du cordon de soudure sur les bords latéraux (non illustré sur la figure 11).In a comparable way, on the figure 12 , the carrying bag 1 is made by means of a single single sheet folded more or less forming a "V" and folding the tip end portion of said "V", so as to constitute the first sheet 2 and the second sheet 3, as well as a pocket 53 disposed on one of the sheets 3 on the bottom side 7 of the container 8, after placing the weld seam on the side edges (not shown in FIG. figure 11 ).
