Ce sachet comprend un corps de sachet 10 ainsi qu'un soufflet 11 replié sur lui-même et un moyen d'ouverture/fermeture. Ce moyen d'ouverture/fermeture est constitué de deux éléments distincts que sont un élément de liaison 12 permettant de maintenir le sachet replié sur lui-même et un élément de liaison 13 susceptible d'ouvertures/fermetures multiples.FIG. 1 shows a packaging bag according to the prior art, once closed. This bag comprises a bag body 10 and a bellows 11 folded on itself and an opening / closing means. This opening / closing means consists of two distinct elements that are a connecting element 12 for maintaining the folded bag on itself and a connecting element 13 capable of multiple openings / closures.

Sur la description qui va suivre, tous les dessins annexés sont présentés avec un unique soufflet situé au niveau de l'embouchure du sachet. Le sachet peut cependant avoir plusieurs soufflets et notamment deux soufflets, dont l'un est disposé au niveau de l'embouchure, l'autre étant disposé sur une face opposée à l'embouchure.In the description which follows, all the accompanying drawings are presented with a single bellows located at the mouth of the bag. The bag may however have several bellows and in particular two bellows, one of which is disposed at the mouth, the other being disposed on a face opposite the mouth.

On a représenté schématiquement sur les figures 2 et 3 annexées, un sachet conforme à la présente invention, à deux stades successifs de sa fabrication.Schematically shown in Figures 2 and 3 attached, a bag according to the present invention, in two successive stages of its manufacture.

Comme on le voit sur la figure 2, à l'origine, le sachet conforme à la présente invention comprend un corps de sachet 20 globalement tubulaire présentant une embouchure d'ouverture 22 et un fond 24 à son extrémité opposée. De préférence, le corps de sachet 20 est défini par quatre parois principales orthogonales entre elles. Sa section est ainsi globalement carrée ou rectangulaire. Deux de ces parois sont illustrées sur la figure 1 sous les références 25 et 26, Les deux parois additionnelles sont respectivement parallèles à chacune de ces deux parois 25 et 26.As seen in FIG. 2, the pouch according to the present invention comprises a generally tubular bag body 20 having an opening mouth 22 and a bottom 24 at its opposite end. Preferably, the bag body 20 is defined by four main walls orthogonal to each other. Its section is thus globally square or rectangular. Two of these walls are illustrated in FIG. 1 under the references 25 and 26, The two walls additional are respectively parallel to each of these two walls 25 and 26.

Les parois du sachet peuvent faire l'objet de nombreux modes de réalisation.The walls of the bag can be the subject of many embodiments.

Il s'agit de préférence de parois en matériau thermoplastique.It is preferably walls of thermoplastic material.

Ces parois peuvent être mono ou multi-couche(s) et mono ou multi-matériau(x). Le cas échéant, il peut s'agir d'un support papier revêtu d'une couche de matériau thermoplastique, ou encore d'une couche thermoplastique métallisée.These walls can be single or multi-layer (s) and mono or multi-material (x). If necessary, it may be a paper support coated with a layer of thermoplastic material, or a metallized thermoplastic layer.

Le sachet 20 peut être réalisé à l'aide d'une feuille unique ou de plusieurs feuilles, par exemple deux feuilles soudées entre elles au niveau de leurs bords, de préférence selon des arêtes reliant les parois principales, par exemple l'arête commune aux parois 25 et 26.The bag 20 can be made using a single sheet or several sheets, for example two sheets welded together at their edges, preferably along edges connecting the main walls, for example the edge common to walls 25 and 26.

Comme on l'a évoqué précédemment, dans le cadre de la présente invention, une partie 30 du corps de sachet 20 est destinée à être repliée sur elle-même sous forme d'un soufflet. L'embouchure 22 et le fond 24 peuvent tous deux être munis d'un soufflet, le sachet 20 comprend donc au moins un soufflet. Cependant, de préférence, cette partie 30 du sachet est formée au niveau de l'embouchure 22. La partie 30 du sachet 20 repliée sous forme d'un soufflet possède une hauteur ℓ1 sensiblement égale à deux fois la largeur ℓ2 du sachet. La hauteur ℓ1 et la largeur ℓ2 précitées du sachet sont considérées perpendiculairement à la ligne 32 de pliage du soufflet.As mentioned above, in the context of the present invention, a portion 30 of the bag body 20 is intended to be folded on itself in the form of a bellows. The mouth 22 and the bottom 24 can both be provided with a bellows, the bag 20 therefore comprises at least one bellows. However, preferably, this portion 30 of the bag is formed at the mouth 22. The portion 30 of the bag folded in the form of a bellows has a height ℓ1 substantially equal to twice the width ℓ2 of the bag. The above-mentioned height ℓ1 and width ℓ2 of the bag are considered perpendicular to the line 32 for folding the bellows.

L'opération de pliage précitée est schématisée par la flèche référencée P sur la figure 2. Le soufflet obtenu est référencé 50 sur la figure 3.The aforementioned folding operation is shown schematically by the arrow referenced P in FIG. 2. The bellows obtained is referenced 50 in FIG.

Le soufflet 50 peut être maintenu ouvert ou fermé par un moyen d'ouverture/fermeture comportant lui-même un premier élément de liaison amovible placé sur le soufflet et un second élément de liaison, les premier et second éléments de liaison étant au moins en partie disposés sur un élément commun. En particulier, les premier et second éléments de liaison peuvent être intégralement disposés au sein d'un seul et unique élément commun. Ces éléments de liaison peuvent faire l'objet de nombreuses variantes de réalisation.The bellows 50 can be held open or closed by an opening / closing means itself comprising a first removable connecting element placed on the bellows and a second connecting element, the first and second connecting elements being at least partly arranged on a common element. In particular, the first and second connecting elements can be fully arranged within a single and unique common element. These connecting elements can be the subject of numerous variants.

Selon un premier mode de réalisation, l'élément de liaison amovible du moyen d'ouverture/fermeture peut être formé d'une bande autocollante. Une telle bande autocollante peut être prévue sur l'extrémité du sachet et du soufflet sous forme de la bande référencée 42 sur la figure 2 et située sur une paroi 26, ou encore sur une paroi opposée à celle portant la bande 42, c'est-à-dire sous la forme de la bande référencée 43 sur la figure 2, ou encore de deux bandes autocollantes complémentaires correspondant aux deux bandes 42 et 43 représentées sur la figure 2. (Ces deux bandes 42 et 43 étant portées en contact lors du pliage du soufflet 50).According to a first embodiment, the removable connection element of the opening / closing means may be formed of a self-adhesive strip. Such a self-adhesive strip may be provided on the end of the bag and the bellows in the form of the band referenced 42 in FIG. 2 and situated on a wall 26, or on a wall opposite to that carrying the strip 42; in the form of the band referenced 43 in FIG. 2, or else two complementary adhesive strips corresponding to the two strips 42 and 43 shown in FIG. 2. (These two strips 42 and 43 being brought into contact during the folding the bellows 50).

Les bandes 42 et/ou 43 précitées s'étendent parallèlement à la ligne de pliage 32 sensiblement sur toute la longueur ℓ3 du sachet, ladite longueur ℓ3 étant considérée parallèlement à la ligne de pliage 32. Les bandes 42 et/ou 43 sont disposées sur des faces internes du sachet 10.The aforementioned strips 42 and / or 43 extend parallel to the fold line 32 substantially over the entire length ℓ3 of the bag, said length ℓ3 being considered parallel to the fold line 32. The strips 42 and / or 43 are arranged on internal faces of the bag 10.

Selon une autre variante de réalisation, l'élément de liaison amovible peut être formé d'éléments complémentaires situées respectivement en lieu et place des bandes 42, 43 précitées et représentées sur la figure 2, c'est-à-dire l'un sur l'extrémité de la paroi 26 du sachet coïncidant avec une extrémité du soufflet 50 et l'autre au niveau de la paroi opposée à la paroi 26 du corps de sachet et destinée à recevoir l'extrémité du soufflet 50 précitée.According to another variant embodiment, the detachable connecting element may be formed of complementary elements located respectively in place of the aforementioned strips 42, 43 and shown in FIG. 2, that is to say one on the end of the wall 26 of the bag coinciding with one end of the bellows 50 and the other at the wall opposite the wall 26 of the bag body and intended to receive the end of the aforementioned bellows 50.

A titre d'exemple non limitatif, de tels éléments complémentaires peuvent être formés de structures complémentaires de type velours/crochet ou encore de profilés mâle/femelle complémentaires, ou même de structures en crochets complémentaires (éventuellement actionnés par un curseur).By way of nonlimiting example, such complementary elements may be formed of complementary structures of velvet / hook type or complementary male / female profiles, or even complementary hook structures (possibly actuated by a slider).

De tels éléments de liaison sont bien connus de l'homme de l'art et ne seront donc pas décrits dans le détail par la suite.Such connecting elements are well known to those skilled in the art and will therefore not be described in detail later.

Selon une variante de mise en oeuvre, toutes les réalisations précédemment citées, peuvent être prévues au sein d'un tape en U installé sur l'extrémité de la paroi 26 du sachet. Dans ce cas, aucune bande ou moyen équivalent n'est nécessaire à l'extrémité de la paroi opposée à la paroi 26. En effet, le cas échéant cette bande 43 ou moyen équivalent est disposée au sein du tape en U, en regard de la bande 42 ou d'un moyen équivalent complémentaire au moyen équivalent de la bande 43.According to an alternative embodiment, all the embodiments mentioned above can be provided within a U-shaped step installed on the end of the wall 26 of the bag. In this case, no band or equivalent means is necessary at the end of the wall opposite to the wall 26. Indeed, if necessary this band 43 or equivalent means is disposed within the U-shaped tape, opposite the band 42 or equivalent means complementary to the equivalent means of the band 43.

Le cas échéant et de façon préférentielle, un curseur 60, représenté sur la figure 3, peut être prévu au niveau de l'élément de liaison 42, 43 amovible pour commander son ouverture/fermeture. Le curseur est un moyen bien connu de l'homme de l'art, il ne sera donc pas décrit en détail.Where appropriate and preferably, a slider 60, shown in Figure 3, may be provided at the connecting member 42, 43 removable to control its opening / closing. The cursor is a means well known to those skilled in the art, so it will not be described in detail.

Le second élément de liaison du moyen d'ouverture/fermeture est de préférence une bande 41 formant partie de l'élément 40. comme représenté sur la figure 2, cet élément 40 est donc constitué de l'ensemble formé par le moyen 42 du premier élément de liaison amovible 42 et/ou 43 et par ladite bande 41. Les premier et second éléments de liaison du moyen d'ouverture/fermeture sont donc disposés sur un élément commun en ce sens que la bande 41 et le moyen 42 appartiennent physiquement à un même élément commun 40.The second connecting element of the opening / closing means is preferably a band 41 forming part of the element 40. as represented in FIG. 2, this element 40 therefore consists of the assembly formed by the means 42 of the first removable connecting element 42 and / or 43 and said band 41. The first and second connecting elements of the opening / closing means are therefore arranged on a common element in that the band 41 and the means 42 physically belong to the same common element 40.

Le cas échéant, la bande 41 peut être constituée d'un support papier revêtu d'une couche de matériau thermoplastique, ou encore d'une couche thermoplastique métallisée.Where appropriate, the band 41 may consist of a paper support coated with a layer of thermoplastic material, or a metallized thermoplastic layer.

Plus précisément encore, et de préférence, la dimension ℓ4 de la bande 41 est telle que l'élément de liaison amovible 42 et/ou 43 ne soit pas sollicité par le contenu du sachet quand le soufflet 50 est maintenu replié sur lui-même, comme schématisé figure 3.More precisely still, and preferably, the dimension ℓ4 of the band 41 is such that the detachable connecting element 42 and / or 43 is not stressed by the contents of the bag when the bellows 50 is kept folded back on itself, as shown schematically in Figure 3.

La bande 41 formant ainsi le second élément de liaison et permettant le maintien à l'état replié sur lui-même du soufflet peut faire l'objet de nombreuses variantes. Il peut s'agir d'une bande autocollante, d'éléments complémentaires de type velours/crochet, d'éléments complémentaires de type mâle/femelle ou encore d'éléments complémentaires de type crochet. Dans tous les cas celui-ci vient se fixer, s'attacher ou se coller au niveau d'une zone 80 externe du corps de sachet 20.The band 41 forming the second connecting element and allowing the maintenance in the folded state on itself of the bellows can be subject to many variants. It may be a self-adhesive tape, complementary elements of velvet / hook type, complementary elements of the male / female type or complementary hook-type elements. In any case, this one comes fix, attach or stick at an outer zone 80 of the bag body 20.

Une fois fixé sur le corps de sachet 20 au niveau de la zone 80, l'élément de liaison 41 assure une fermeture qui ne peut être ouverte qu'une seule fois selon un mode de réalisation. Cependant, et de préférence, un curseur 70 commandant une ouverture/fermeture de l'élément de liaison 41 est prévu. Celui-ci est installé sur la face externe de l'élément de liaison 41 de sorte qu'il soit accessible quand le soufflet 50 est replié sur lui-même, et prévu pour se déplacer selon une ligne 45, s'étendant longitudinalement sur l'élément 41, et séparant ou joignant les deux parties 44 et 46 de l'élément de liaison 41.Once attached to the bag body 20 at the area 80, the connecting member 41 provides a closure that can be opened only once in one embodiment. However, and preferably, a slider 70 controlling opening / closing of the connecting member 41 is provided. It is installed on the outer face of the connecting element 41 so that it is accessible when the bellows 50 is folded on itself, and intended to move along a line 45, extending longitudinally on the outside. element 41, and separating or joining the two parts 44 and 46 of the connecting element 41.

On a représenté sur la figure 4 un mode de réalisation particulier où l'élément de liaison 41 est cette fois-ci complémentaire à la bande 43 du premier élément de liaison pour former un ensemble commun 40 alors disposé avant l'opération de pliage sur la face du corps de sachet 20 située à l'opposé de la paroi 26.FIG. 4 shows a particular embodiment where the connecting element 41 is this time complementary to the band 43 of the first connecting element to form a common assembly 40 then disposed before the folding operation on the face of the bag body 20 located opposite the wall 26.

Dans ce mode de réalisation, on retrouve tous les moyens décrits précédemment. Ce mode de réalisation présente toutefois l'inconvénient de rendre accessible depuis l'extérieur, le premier élément de liaison 42 et/ou 43 amovible contrairement au mode de réalisation présenté sur la figure 3.In this embodiment, all the previously described means are found. This embodiment however has the disadvantage of making accessible from the outside, the first connecting element 42 and / or 43 removable unlike the embodiment shown in Figure 3.

On a représenté sur les figures 5a et 5b le moyen d'ouverture/fermeture conforme au mode de réalisation préféré de l'invention et présenté sur la figure 3.FIGS. 5a and 5b show the opening / closing means according to the preferred embodiment of the invention and shown in FIG.

Selon un mode de réalisation de l'invention présenté sur la figure 5a, le moyen d'ouverture/fermeture est constitué de deux ensembles physiques distincts, l'un formé par le moyen 43 et l'autre formé par la bande 40 comprenant elle-même le moyen 42 et la bande 41.According to one embodiment of the invention presented in FIG. 5a, the opening / closing means consists of two distinct physical assemblies, one formed by the means 43 and the other formed by the band 40 comprising itself. even the medium 42 and the band 41.

Selon un autre mode de réalisation de la présente invention présenté sur la figure 5b, le moyen d'ouverture/fermeture est constitué d'un tape en U. Dans ce cas, les éléments complémentaires que sont les moyens 42 et 43 et l'élément de liaison 41 appartiennent tous à un même élément commun 40, qui dans le cas présent est le tape en U lui-même. Dans le cas de l'utilisation d'un tape en U, on comprend qu'une partie 400, située à l'extérieur de cet élément commun 40 doit prévoir des moyens d'adhésion au soufflet.According to another embodiment of the present invention shown in FIG. 5b, the opening / closing means consists of a U-shaped tap. In this case, the complementary elements that are the means 42 and 43 and the element link 41 all belong to the same common element 40, which in this case is the U-shaped itself. In the case of the use of a U-shaped tape, it is understood that a portion 400, located outside this common element 40 must provide means for adhesion to the bellows.

Dans les deux variantes présentées sur les figures 5a et 5b, on note la présence des curseurs 60 et 70 pouvant être mis en oeuvre et dont la structure est représentée de façon schématique. De plus, dans les deux cas, le sachet ne peut pas être ouvert sans que l'élément de liaison 41 n'ait été séparé en deux parties par le déplacement du curseur 70 (ouvertures/fermetures multiples) ou par la rupture d'une ligne de faiblesse (ouverture/fermeture unique) en lieu et place du curseur le cas échéant. Dans ces variantes de réalisation du moyen d'ouverture/fermeture, l'élément de liaison 41 permet donc de remplir une fonction de témoin d'inviolabilité à l'ouverture du sachet. De plus, dans le cas de l'utilisation d'un tape en U, il faut de plus rompre une ligne de faiblesse 410 pour accéder au contenu du sachet.In the two variants shown in FIGS. 5a and 5b, note the presence of sliders 60 and 70 that can be implemented and whose structure is schematically represented. In addition, in both cases, the bag can not be opened without the connecting element 41 being separated in two parts by the displacement of the slider 70 (multiple openings / closures) or by the breaking of a line of weakness (single opening / closing) in place of the cursor if any. In these alternative embodiments of the opening / closing means, the connecting element 41 thus makes it possible to fulfill a function of inviolability control at the opening of the bag. In addition, in the case of using a U-shaped tape, it is also necessary to break a line of weakness 410 to access the contents of the bag.

La figure 6 présente une variante de réalisation du moyen d'ouverture/fermeture et ce conformément à la réalisation présentée sur la figure 4, c'est-à-dire où l'élément 40 est formé par le moyen 43 et la bande 41. Dans ce mode de réalisation, bien que l'élément de liaison 42, 43 soit accessible depuis l'extérieur, le tape en U assure une fonction d'inviolabilité du contenu du sachet dans la mesure où une ligne de faiblesse 410 doit être rompue pour accéder au contenu du sachet. Là encore des curseurs 60 et 70 sont représentés sur le moyen d'ouverture/fermeture et peuvent être mis en oeuvre conformément à la description réalisée à l'appui de la figure 4.FIG. 6 shows an alternative embodiment of the opening / closing means and in accordance with the embodiment shown in FIG. 4, that is to say, where the element 40 is formed by the means 43 and the band 41. In this embodiment, although the connecting element 42, 43 is accessible from the outside, the U-shaped tape provides a tamper-proof function of the contents of the bag insofar as a line of weakness 410 must be broken for access the contents of the bag. Again sliders 60 and 70 are shown on the opening / closing means and can be implemented in accordance with the description made in support of Figure 4.

Contrairement aux modes de réalisation présentés sur les figures 5a et 5b et 6, il peut également être envisagé que le moyen d'ouverture/fermeture ne soit pas constitué d'une ou plusieurs pièces rapportées sur le corps de sachet 20 mais qu'il soit une partie même du corps de sachet 20, formant ainsi un appendice de ce sachet.In contrast to the embodiments shown in FIGS. 5a and 5b and 6, it can also be envisaged that the opening / closing means does not consist of one or more inserts on the bag body 20 but that it is a portion of the bag body 20, thereby forming an appendix of this bag.

Dans tous les cas, la présente invention est avantageuse vis-à-vis de l'art antérieur du fait que la mise en oeuvre et la fabrication d'un sachet d'emballage avec les caractéristiques présentées sont simplifiées.In any case, the present invention is advantageous vis-à-vis the prior art because the implementation and manufacture of a packaging bag with the features presented are simplified.
