Description
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.
Sont notamment connus les documents suivants portant sur un sac de transport par réseau pneumatique :
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
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.
