FR2869593A1 - Package for transport of e.g. medical collections, has three seams, where one seam is extended along edge of bag and other seams are inclined from edge of bag towards inner side of bag to delimit opening of bag - Google Patents

Abstract

The package has a bag, made of plastic material, with an opening (3) that is closed by a pre-pasted foldable flap (4) on a side. Each side of the bag has an end portion near its opening (3) and three seams (6-8). The seam (6) is extended along the edge of the bag and the seams (7, 8) are inclined from the edge of the bag towards an inner side of the bag to delimit the opening of the bag.

Description

The present invention relates to a package especially for transport

objects.

  More particularly, the invention relates to a package especially for the transport of objects such as funds, for example in the form of bills, in a pneumatic network.

  The applicant has already proposed in EP A 0 664 264, a package of this type which comprises a bag made of welded plastic material and having an opening closable by a pre-bonded flap and on at least one side of this bag, a pocket propulsion of this packaging by compressed air network.

  Such packages have many applications for example in large areas between the boxes and a fund receiving room.

  It has been demonstrated that the use of a propulsion pocket on each side of the bag made it possible to obtain very reliable transport.

  Other applications of these packages have been considered.

  For example, such packaging and such networks can also be used, for example, in hospitals to transport objects such as, for example, blood or other blood samples, between a sampling room and a room. analysis.

  It is then appropriate that the packaging has a very good seal.

  The object of the invention is therefore to propose such a package.

  For this purpose, the subject of the invention is a packaging, in particular for transporting objects in a pneumatic network, comprising a bag made of welded plastic and having an opening that can be closed by a pre-glued flap and on at least one face of this bag, a bag of propulsion of this packaging by the compressed air of the network, characterized in that each side of the bag has on at least one end portion located near its opening at least two weld lines of which one extends along the edge of the bag and the other is inclined from this edge to the inside of the bag to define the opening thereof.

  According to other characteristics: the bag has on its periphery two weld lines, and the bag comprises a propulsion pocket on each of its faces.

  The invention will be better understood from the following description given solely by way of example and with reference to the appended drawing which shows a perspective view of an exemplary embodiment of a packaging according to the invention. invention.

  It has in fact illustrated in this figure, a particular packaging for the transport of objects such as medical samples in a pneumatic network implanted for example in a hospital or other.

  This package is designated by the general reference 1 and comprises a bag designated by the general reference 2 made of welded plastic material.

  This bag has at one end an opening designated by the general reference 3, closable by a pre-glued folding flap designated by the general reference 4.

  At the other end, this bag has on at least one of its faces, and preferably on each of them, a propulsion pocket of this packaging by compressed air network.

  One of these pockets is illustrated in this figure and is designated by the general reference 5.

  The aforementioned EP A 0 664 264 describes in detail the production of such a bag and such bags.

  As illustrated, the bag has on its periphery at least one weld line which is designated by the general reference 6.

  In the illustrated example, this weld line then extends over the three free edges of the bag to define the opening 3 of the package.

  According to the invention, each side of the bag has on at least one end portion located near its opening, at least two weld lines, one of which corresponds to the weld line 6 described above and which extends along the edge of the bag and the other is inclined from this edge to the inside of the bag to define the opening thereof.

  These lines of inclined welds are for example designated by the general references 7 and 8 in this figure.

  The bag then has at least on this end portion located near its opening, at least two weld lines that provide a very good seal of the package when the pre-glued flap is folded to close the- this.

  Of course, other embodiments can be envisaged and other configurations of the inclined weld lines can be envisaged.

  Similarly, a double weld line may be provided along the three edges of the bag to further ensure a better seal thereof.

  It is then conceivable that, thanks to such a structure, the packaging according to the invention is perfectly adapted to the transport of objects such as, for example, blood samples or the like in pneumatic networks implanted in hospitals because of their good sealing, which makes it possible to avoid any contamination of the network in case of problems at the object such as for example breakage or leakage.

Claims (3)

  1. Packaging especially for the transport of objects in a pneumatic network, comprising a bag (2) made of welded plastic material having an opening (3) closable by a pre-glued folding flap (4) and on at least one side thereof bag, a pocket (5) for propelling this package by the compressed air of the network, characterized in that each side of the bag has on at least one end portion located near its opening (3), at least two weld lines (6, 7, 8), one of which (6) extends along the edge of the bag and the other (7, 8) of which is inclined from that edge towards the inside of the bag so delimit the opening (3) thereof.   2.
