Abstract

The invention relates to a flexible bag for carrying articles, comprising a closed lower part and lateral walls 2-5, characterised in that it furthermore comprises at least one flexible internal partition 8 whose two opposite edges 15 are at least locally fastened to the said lateral walls in order to define with the latter at least two pockets 9, 10 which are separated by the said internal partition for the reception of articles without contact between them, the said flexible internal partition being able either to be folded back against the lateral walls, or to be deployed for the definition of the said two pockets by deformation of at least the internal partition.

Description

The invention relates to flexible bags for transporting articles, in particular

  particular, but not exclusively, for the transport of food products, these products

  being themselves in bulk or packaged.

  These flexible bags can be made of any material

  suitable known, for example made of paper, plastic or textile.

  The invention applies very particularly, but not limited to, such flexible bags which are used by the consumer for the transport of food articles,

  especially in the field of fast food.

  It is often desirable, in particular in the field of fast food, to be able to isolate an article from the others, that is to say to put it out of contact with the latter. This is particularly the case of an article which is in the form of a refrigerated drink, the packaging of which may be covered with condensation water, of which

  we wish to avoid contact with other food items (for example bread). This is also the case for 2 an item which, if it is brought into contact with other items, can deteriorate or on the contrary deteriorate these articles by reception or transmission of odor or taste.

  Soft bags of this kind currently available on the market are in the form of a single pocket in which the various articles are arranged successively and

  are therefore in contact with each other, which causes the above-mentioned drawback.

  The object of the invention is to provide a flexible bag of the kind in question which, without appreciable increase in the cost price and without requiring delicate handling on the part of the user, allows the latter, if he so desires. , to be able to

isolate items.

  To this end, the flexible bag according to the invention comprising a closed lower part and side walls is characterized in that it also comprises at least one flexible interior partition, two opposite edges of which are at least locally subject to said walls side to define with them at least two pockets which are separated by said interior partition, for the reception of articles without X:: -: ::: :: \:

  contact between them, said flexible interior partition being able to be either folded against the side walls, or deployed for the definition of said two pockets by deformation of at least said interior partition.

  With such an arrangement, the user therefore has two pockets, namely a main pocket and an auxiliary pocket, the latter being obtained by deployment and

  deformation of the interior partition and possibly of at least one of the side walls for the reception of at least one particular article which is thus separated, by the interior partition, from the other articles contained in the main pocket.

  The flexible interior partition advantageously extends

  from the bottom of the bag over all or part of the height thereof. It is preferably subject to the side walls by its two substantially vertical longitudinal edges, the connection of the flexible interior partition with the side walls being over all or part of the height of said partition.

  According to a first embodiment, the bag is.

  foldable flat and it has a bellows on two opposite side walls, the flexible interior partition also being in the form of a bellows and extending in the vicinity of one of said side bellows walls so that it can be folded with and against it. The flexible interior partition is preferably secured by its longitudinal edges on the two side walls which border said side bellows wall. In this embodiment, the flexible interior partition defines, with said side bellows wall, the auxiliary pocket, the horizontal cross section of which can either decrease downwards or be constant.

  According to a second embodiment, the bag is also foldable flat and it still has a bellows on two opposite side walls, but this time the flexible interior partition is secured by its longitudinal edges, for example vertical, on one of the walls side which connect the side walls of bellows, the flexible internal partition extending along said side wall the connection so that it can be left flat against rejection- Arn4a-o a'nit Ztre deformed towards the inside of the bag 1à -. r -3

to define the auxiliary pocket.

  In the first embodiment, the auxiliary pocket is obtained by deployment of the flexible intermediate partition in the form of a bellows, which makes it possible not to deform or to deform only slightly the adjacent side wall 5 of bellows. In the second embodiment, the auxiliary pocket is obtained again by deformation of the flexible interior partition, but this time with approximation of its longitudinal edges, which also deforms the wall

  lateral which receives the interior partition.

  The invention will be clearly understood on reading the description which follows and with reference to the accompanying drawings in which: Figure 1 - is a schematic perspective view of a flexible bag drawn up according to a first embodiment of the invention, this bag being of the folding type and being shown in the partially open state, the interior partition being folded against a side wall of bellows .; Figure 2 - is a view similar to Figure 1 and shows the bag in the fully open state, the interior partition being 2 deployed for the formation of the auxiliary pocket; Figure 3 - is a plan view of the bag of Figure 1 .; Figure 4 - is a plan view of the sacdan 'state of Figure 2, the bag containing articles which are separated by the interior partition .; 2 Figure 5 - is a horizontal section in the plane V-V of Figure 2; Figure 6 - is a section cut away in the vertical plane VI-VI of Figure 2; Figure 7 - is a view similar to Figure 6 and shows 3 a variant for the shape of the auxiliary pocket; Figure 8 - is a view similar to Figure 2 and shows a bag established according to the second embodiment of the invention; Figure 9 - is a horizontal section of the bag of Figure 8 taken in the plane IX-IX; Figure 10 - is a vertical section of the bag of Figure 8

taken in the X-X plane.

  By way of nonlimiting example, there is shown in the drawings according to two embodiments a bag which is 259868s. made entirely of paper and which is of the folding type, this bag being intended to receive food products in bulk or packaged for the particular application

fast food.

  As shown in the drawings, the bag has a bottom 1 and side walls 2, 3, 4, and 5. In known manner, this bag is obtained by folding and gluing a sheet of paper, lines 6 of pre- folding being provided on the walls

  side 2 to 5 to allow the folding of the bag flat.

  The two opposite side walls 3 and 5 are of the O bellows type and, for this purpose, they each have a vertical folding line 7 participating in the flat folding and in the deployment of the bag. According to the invention, the bag is also made to comprise, as described above, at least one flexible interior partition, two opposite edges of which are at least locally secured to the side walls 2 to 5 to define with them at least two pockets, namely a main pocket and an auxiliary pocket which are separated by said interior partition for receiving articles without contact with each other, this flexible interior partition can be folded against one of said walls

  i lateral, or deployed for the definition of said two I | pockets by deformation of at least said interior partition.

  In the two embodiments shown, the interior partition extends from the bottom 1, preferably over the entire height of the bag, that is to say to the upper edge of the side walls 2 to 5. interior partition

  is secured to the side walls by its two longitudinal edges which are substantially vertical.

  In the first embodiment, represented in FIGS. 1 to 7, the interior partition 8, which is made of paper

  like the rest of the bag, is also in the form of a bellows and it extends in the vicinity of the side wall 5 of bellows.

  The internal partition 8 is subject to the two opposite lateral walls 2 and 4 which border the lateral bellows partition 5. It is fixed to the internal face of the lateral walls 2 and 4, in the vicinity of the junction of

these with the wall 5.

  In FIGS. 1 and 3, the bag is shown in the partially open state, the internal partition 8 being in its

  initial position folded against the side wall of the bellows 5.

  In FIGS. 1 and 3, the bag is shown in the partially open state, the internal partition 8 being in its initial position folded against the side wall of bellows 5. In this state of the bag, the user, if he continues deploying the bag without manually acting on the interior partition 8, has only the main pocket 9, the auxiliary pocket 10, which is defined between the interior partition 8, the side wall 5 and the two marginal zones of the side walls 2 and 4 which are close to the wall 5, being of zero volume. In FIGS. 2 and 4 to 7, the bag is in the fully deployed state, the partition 8 having been manually moved away from the side wall 5 for the definition of the auxiliary pocket, As shown in FIG. 4, the user can place in the auxiliary pocket 10 at least one conditioned article 11 or loose articles 12 which are separated from the conditioned articles 13 or loose 14 received in the main pocket 2 9, In the arrangement of FIGS. 1 to 6, the internal partition flexible 8 is secured to the side walls 2 and 4 along its two longitudinal zones 15, the width of which goes downwards increasing, so that, as visible in particular in FIGS. 2 and 6, the horizontal cross section 2 of the auxiliary pocket 10 decreases downwards until it is, for example, substantially at the level of the bottom 1. In

  this arrangement, the internal partition 8 may have at its lower part, a flap 16 which, from the junction between the side wall of bellows 5 and the bottom 1, extends along the latter towards the inside from the bag.

  In the arrangement of FIG. 7, the two vertical longitudinal marginal zones 15 ′ for fixing the internal partition 8 to the side walls 2 and 4 (the side wall 2 is not visible in this figure) are of constant width. so that the auxiliary pocket 10 has a sectio

  constant horizontal right from top to bottom of the bag.

  The bag 3 according to the second embodiment of the invention, represented in FIGS. 8 to 10, differs from that {-j LEn of FIGS. 1 to 7 only by the arrangement and the arrangement of the interior partition. In this embodiment, the interior partition 108 is rectangular in shape, substantially the same area as the side walls 2 and 4, and it is fixed by gluing along its two vertical marginal zones 115 to the partition 2 its 2, respectively at in the vicinity of the side walls of the bellows 3 and 5. The internal partition 108 extends over the same width and the same height as the side wall 2, the marginal bonding zones 115 extending over a portion

  only from the height of the bag, from the bottom 1, but alternatively extending over the entire height of the bag.

  In the state shown in Figure 8, the bag is deployed but the interior partition 108 is left against the side wall

  2, so that the auxiliary pocket 110 is of zero volume.

  On the opposite side, in the state shown in FIGS. 9 and 10, the partition 108 has been moved towards the inside of the bag by bringing together its marginal zones 115, while the side wall 2 has been deformed towards the outside, this which causes the deformation of the auxiliary pocket 110 for the reception of at least one conditioned article 111 or loose articles 112 12 which are separated, by the partition 108, from the conditioned articles 113 or loose 114 contained in the main pocket 109. As shown in phantom in line 10, the part of the partition 108 which is located above the marginal zones can be folded down either towards the pocket 109 or towards the

2 pocket 110.

  It appears from the above that the invention allows, without appreciable increase in its price, to obtain a bag, in particular a paper throwing bag, intended to receive food products which allows the user to have 3 to an optional pocket in which he can place at least one article while keeping it out of contact with

  the item (s) contained in the main pocket.
