Abstract

The enclosure (1) has a bag that is made of a flexible plastic material. The bag has stacking sides (21), where the side has a thinning line (30) with a resistive force that is less than a deflagration force such that the bag is opened along the line, following a deflagration. The lines extend on a major part of dimension of a side for allowing passage of a product that stains a set of stacked articles, after the deflagration. The sides extend on sides of a welded edge (15) of the bag. Each line extends parallel to the edge at a distance comprised between 3 and 30 millimeter.

Description

The present invention relates to the technical field of flexible packaging intended for the transport of articles such as, preferably, banknotes.

In the preferred technical field of fundraising, it is known to stack the notes inside a flexible pouch type envelope. This envelope comprises a welded flexible plastic bag having an access passage to its closed internal volume, closable by a secure closure means such as a secure adhesive tape or a hot melt glue for example.

After filling and closing, these envelopes are intended to be placed next to each other inside a drawer of a container which is equipped with a system for neutralizing articles by smearing in the event of unauthorized opening. of the container. Thus, in case of break-in of the container, a pyrotechnic system is triggered leading to the dispersion of a smearing product inside the container. To allow the smudging of the articles placed in the envelopes, the walls of the envelopes are provided with passage holes for the smudge product which thus renders the articles placed inside these envelopes unusable.

Such an envelope is unsatisfactory in practice because it does not provide all the required security guarantees. Indeed, it has been found the possibility of extraction of notes through the passing holes of the smudge product. Moreover, such an envelope is relatively expensive and difficult to manufacture since it requires the realization of calibrated holes and the removal of material falls corresponding to these passage holes.

The present invention therefore aims to overcome the drawbacks stated above by providing a new envelope with a reduced manufacturing cost and total security while being able to be used in a smudging neutralization system.

To achieve such an objective, the envelope according to the invention is adapted to contain a series of stacked articles resting by their edge and thus forming a stack of articles, the envelope comprising a flexible plastic bag. welded, having an access passage to its closed internal volume, closable by a secure closure means, the bag having a first and second stacking sides extending opposite the slices of the stack of items. At least the first stacking side is provided with at least one line of weakening having a resistance force less than a deflagration force so that after a deflagration, the bag opens from this line of weakening, this line of weakening extending over most of at least one dimension of said side so as to ensure, after the explosion, the passage of a smudge product from smearing all the articles stacked.

According to a preferred embodiment, the envelope has a symmetry of embodiment providing total reversibility. For this purpose, the second stacking side of the envelope is also provided with at least one weakening line having a resistance force less than a deflagration force so that, following a deflagration, the bag opens from this line of weakening, this weakening line extending over most of at least one dimension of said side so as to ensure, after the blast, the passage of a smearing product coming smear all the stacked items.

According to a first embodiment, the first and / or second stacking side extends on either side of a welded edge of the bag, at least one weakening line being arranged on the one and / or or both sides of the welded edge, extending away from said welded edge.

For example, each weakening line extends substantially parallel to the adjacent welded edge at a distance of between 3 mm and 30 mm, and over the greater length of this welded edge.

For example, at least two lines of weakness are arranged on the first and / or second stacking side, on one and / or the other side of the welded edge, extending substantially parallel to each other and at the welded edge, and at a distance from each other and from the welded edge.

According to another embodiment, for which the envelope is intended to be laid flat, each stacking side extends between two welded edges opposite of the bag, at least one line of weakness being arranged between the two welded edges.

For example, the first and / or second stacking side has weakening lines extending diagonally and parallel to the two welded edges.

Advantageously, each weakening line is formed by pre-cuts.

For manufacturing and reversibility issues, the weakening lines are symmetrically formed on the stacking sides.

As is apparent from the invention, the first and second stacking sides respectively form inlet sides for a product smear and support on the bottom of a system of neutralization articles by a smear product .

As is apparent from Figures 1 to 3, the object of the invention relates to an envelope 1 for containing articles such as preferably banknotes and schematically represented by the reference 2. These items 2 are placed next to one another inside the envelope so as to form a stack 3. This envelope 1 is intended to be placed inside a container 4 adapted to be used in the context of a system for neutralizing articles 2 with the aid of a smearing product.

In the example shown, the container 4 is a drawer having a bottom 5 extending opposite an opening 6 from which is distributed a smearing product. The envelope 1 is intended to be placed inside the drawer 4 so that the articles 2 rest by their edge on the bottom 5 of the drawer. The stack 3 of the articles delimits, and by their opposite edges, a support side 8 on the bottom 5 and an opposite side 9 , said arrival of the smearing product and oriented towards the opening 6 of the drawer.

As is more specifically apparent from Figure 2, the casing 1 is in a known manner in the form of a bag 11 of flexible plastic material preferably recyclable such as polyethylene. The bag 11 has a so-called recto face 12 and a so-called reverse side 13 delimited by two opposite transverse edges 14 substantially parallel to each other and two opposite longitudinal edges 15 substantially parallel to each other. In a conventional manner, the envelope 1 has a generally rectangular shape.

The faces 12 and 13 of the bag 11 are made from at least one folded flexible plastic sheet or at least two superimposed flexible plastic sheets, at least some of whose edges are welded so as to delimit a closed internal volume. In the illustrated example, the two longitudinal edges 15 are welded while one of the transverse edges 14 is welded, the other edge being formed by a fold. Of course, it is clear that it can be expected that the four sides of the envelope have welded edges. The closed internal volume of the bag 11 is accessible through an access passage 16. In the illustrated example, the access passage 16 is constituted by means of a slot arranged in the front face 12 between the two longitudinal edges. 15 and near a transverse edge 14. Of course, it is clear that such an access passage 16 can be made at any location of the package. The access passage 16 is closed by means of a secure closure means 17, such as a security adhesive tape constituting a tamper evidence. Such secure closure means 17 may consist of a flap provided with adhesive with a protection.

As is more specifically apparent from FIGS. 1 and 3, the envelope 1 is intended to contain a stack 3 of articles 2 intended to rest by their edge on a support such as the bottom 5 of the drawer 4. In this position, the bag 11 has a first 21 and a second 22 stacking sides extending opposite each other and facing the sides 8, 9 of the stack 3. the example illustrated in the drawings, the first 21 and second 22 stacking sides extend vis-a-vis respectively the arrival side 9 of the smearing product and the support side 8 of the stack 3 . in other words, when the envelope 1 containing a stack 3 of articles 2 is placed within the container 4, the first stacker 21 side is the upper portion of the casing situated substantially opposite the opening 6 of the drawer 4 while the second stacking side 22 corresponds to the lower part of the package situate it is substantially opposite the bottom 5 of the drawer.

According to the invention, at least the first stacking side 21 of the envelope is provided with at least one weakening line 30 having a resistance force less than a deflagration force so that, following a deflagration, the bag opens from this line of weakness 30 which thus constitutes a tear initiation. It should be noted that this line of weakness 30 is designed not to weaken the mechanical strength of the envelope during handling operations, filling and handling.

According to another characteristic of the invention, this weakening line 30 extends over most of at least one dimension of said stacking side 21 so as to ensure, after the blast, the passage of a product of smearing staining all the stacked articles 2. It must be considered that in case of attempted fraudulent access to the container 4, the associated pyrotechnic system is triggered leading to a blast whose blast leads to the appearance of a deflagration force causing the opening of the bag 11 along the line of weakness 30. The pyrotechnic system also causes the emission of a smearing product is distributed from the opening 6 of the drawer. Such a smearing product is therefore able to penetrate the inside of the envelope from the opening of the bag 11 extending along the line of weakness 30.

In the example illustrated in Figures 2 and 3, each stacking side 21, 22 extends on either side of a welded longitudinal edge 15. In this example, a weakening line 30 is arranged from and further the longitudinal welded edge 15 extending away from said welded edge. The weakening line 30 is located at a distance from the adjacent welded longitudinal edge 15 of between 3 mm and 30 mm and for example of the order of 6 mm. According to this embodiment, the first stacking side 21 is thus provided with two weakening lines 30.

It should be understood that the first stacking side 21 is provided with one or more lines of weakness 30 distributed on the surface of this side so as to obtain a smear of all the items 2. In the example 2 and 3, each line of weakness 30 extends over substantially the entire length of the stack 3. The lines of weakness 30 are distributed equally along the width of the stack 3 while being arranged on the on the other hand, the welded edge 15 to allow the smudging of all the products 2. Of course, the weakening lines 30 may be arranged perpendicular to the welded edge 15 and distributed over the entire length of the stacking side 21.

Of course, it can be envisaged to make a single line of weakness in the first stacking side 21. Similarly, as illustrated in FIG. 1, the first stacking side 21 of the envelope can be provided with two weakening lines provided on one and / or the other side of the adjacent welded longitudinal edge 15 extending parallel to each other and to the welded edge and at a distance from each other and the welded edge 15. According to this example, the first stacking side 21 is thus provided with four lines of weakness 30. Of course the first stacking side 21 may be provided with a different number of lines of weakness 30.

It follows from the above description that the width of the stacking sides 21, 22 depends on the width of the stack 3 and consequently the number of stacked articles 2 . The first 21 or second stacking side 22 corresponds to a more or less large part of the front faces 12 and back 13 extending from a longitudinal edge 15.

In the illustrated examples, the weakening line 30 extends in a substantially rectilinear direction parallel to the longitudinal welded edge 15. Of course, it can be envisaged that each line of weakness 30 is not rectilinear. For example, each line of weakness 30 may consist of one or more curved segments.

In the same direction, the weakening lines 30 can be arranged in the front face 12, between the secure closing means 17 and the transverse edge 14 farthest as illustrated in Figure 2. The reverse side 13 may comprise lines of weakening 30 arranged symmetrically with respect to those of the front face 12. Of course, the weakening lines 30 arranged in the reverse side 13 which does not include the secure closing means 17, can extend between the two transverse edges 14 as shown in Figure 3. Similarly, the weakening line or lines 30 arranged on the front face 12 may be extended between the secure closing means 17 and the transverse edge 14 closest, as is apparent on the central packaging shown in Figure 1.

Advantageously, each line of weakness 30 is formed by pre-cuts made in the faces of the envelope mechanically or by laser. It is clear that the number of weakening lines and their distribution on the first stacking side 21 depends on the dimensions of this side and consequently on the format of the envelope.

According to a preferred embodiment, the second stacking side 22 of the envelope is also provided with at least one line of weakening 30 having a resistance force less than a deflagration force so that following a deflagration, the bag 11 opens from this line of weakness. After the blast, this line of weakness, which extends over most of at least one dimension of the underside, allows the passage of the smudge product from smearing all the stacked articles. The second stacking side 22 of the package is provided with one or more lines of weakness 30 as explained above for the first Stacking side 21. For manufacturing and reversibility of the envelope, stacking sides 21, 22 preferably have the same number and organization of lines of weakness 30 . Preferably, the weakening lines 30 are symmetrically formed on both stacking sides 21, 22.

Such an envelope 1 can be placed indifferently, by its first 21 or second stacking side 22, on the bottom 5 of the container in view of its symmetrical embodiment of these stacking sides 21, 22. It should be noted that the weakening lines 30 of the stacking side, which is resting on the bottom 5, namely the second side 22 in the illustrated example, contribute to the smearing of the articles 2 by possibly tearing, soaking and / or by capillarity. It should be noted that the excess staining product is retained by the bottom of the drawer on which the stacking side 22 of the envelope is in contact.

Figures 4 and 5 illustrate an alternative embodiment in which the casing 1 has a large dimension and is placed flat on the bottom 5 (Figure 1). According to this variant embodiment, each stacking side 21, 22 corresponds to the major part of the respectively front face 12 and back 13 of the envelope. Each stacking side 21, 22 thus extends between the two opposite transverse edges 14 and the longitudinal edges 15. In this embodiment, one and preferably each stacking side 21, 22 comprises a series of lines of weakness 30. for example, each side of stack 21 and 22 comprises two weakening lines 30 extending diagonally 30 and a median line of weakness extending parallel to the longitudinal edges welded 15. in the example illustrated in FIG. 4, the diagonal weakening lines 30 are formed discontinuously outside the central part of the face of the envelope. It should be noted that the median weakening line 30 can also be arranged discontinuously to extend outside the central portion of the face of the envelope.

According to this last variant embodiment, the articles 2 extend substantially parallel to the transverse edges 14, unlike the embodiment shown in FIG. 3, where the articles 2 extend substantially parallel to the longitudinal edges 15. note that he can it is expected that the stacking sides 21, 22 extend on either side of the transverse sides 14 or between the two longitudinal sides 15.

According to another characteristic of the invention, the casing 1 may be provided with propulsion means in a pneumatic conveying network. For this purpose, the casing 1 may be provided, for example, with one or more fins or a bottom bellows or any other means of propulsion. For example, these propulsion means may be provided with lines of weakness 30 as described above. The envelope 1 can thus transport articles 2 inside a pneumatic network. It should be noted that the envelopes 1 as described above can be placed in a collection envelope which is itself provided with lines of weakness 30 as described above.
