Definitions

  • 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.
  • 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.
  • 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.
  • a medical environment such as blood samples, bone marrow samples, medicines, anesthetics, vaccines or even other products.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the weld bead is implemented only on the side edges of the sheets.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

  • 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.
  • the carrying bag in one embodiment, it comprises two pockets respectively arranged on the outer faces of the two sheets.
  • 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.
  • 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.
  • the transport bag in another embodiment, 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.
  • the two sheets and the at least one pocket are implemented by means of a single sheet.
  • the carrying bag 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.
  • 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.
  • 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.
