The present invention relates to a flexible plastic bag of the type obtained from at least one strip of plastic film shaped so as to determine by soldering a bottom on which the bag rests, two side walls, an area stiffening and gripping connecting the two side walls and a front face also connecting the two side walls, said front face corresponding to the side where the pouring of the contents of the bag after opening thereof.
Des sachets de ce type sont en eux-memes connus. Sachets of this type are known in themselves.
Ils ont fait par exemple, mais non limitativement, l'objet des demandes de brevet en FRANCE 75-18258, i8-04233, 80-02187, 83-18257 au nom de la demanderesse, demandes auxquelles il est fait ici expressément référence.They have, for example, but not limited to, been the subject of patent applications in FRANCE 75-18258, i8-04233, 80-02187, 83-18257 in the name of the applicant, requests to which express reference is made here.
Ces sachets donnent entière satisfaction et les résultats annoncés dans les demandes précitées sont obtenus. These sachets give complete satisfaction and the results announced in the aforementioned requests are obtained.
Pour les sachets de grande contenance, toutefois, il est apparu qu'il etait encore nécessaire de parfaire la stabilité du sachet pour éviter son renversement sur les côtés ou son basculement vers'l'avant. For large-capacity sachets, however, it appeared that it was still necessary to perfect the stability of the sachet to prevent it from overturning on the sides or tilting forwards.
La presente invention se propose de remédier à ces inconvénients. The present invention proposes to remedy these drawbacks.
Ce résultat est obtenu avec un sachet en matière synthétique souple du type obtenu à partir d'au moins une bande de film de matière synthetique conformée de manière à déterminer par des soudures un fond sur lequel repose le sachet, deux parois latérales, une zone de rigidification et de préhension reliant les deux parois laterales et une face frontale reliant également les deux parois latérales, ladite face frontale correspondant au côte où s'opere le versage du contenu du sachet après ouverture de celui-ci caractérise en ce que la face frontale est munie d'un moyen de rigidification et de stabilisation du sachet. This result is obtained with a flexible plastic bag of the type obtained from at least one strip of plastic film shaped so as to determine by soldering a bottom on which the bag rests, two side walls, a zone of stiffening and gripping connecting the two side walls and a front face also connecting the two side walls, said front face corresponding to the side where the contents of the bag are poured after opening thereof characterized in that the front face is provided with a means of stiffening and stabilizing the bag.
Le moyen de maintien et de stabilisation peut consister par exemple en un contrefort rigide. Ledit contrefort peut être en toute matière, par exemple en carton, PVC, ou toute autre matière synthetique. The holding and stabilizing means may consist, for example, of a rigid buttress. Said buttress can be of any material, for example cardboard, PVC, or any other synthetic material.
Le contrefort pourra également remplir d'autres fonctions, telles que par exemple coopérer à la fermeture du sachet. The buttress may also fulfill other functions, such as for example cooperating in the closure of the bag.
Selon un autre mode de mise en oeuvre, le moyen de maintien consistera en une ou plusieurs nervures de rigidification verticales ménagées au niveau de ladite face latérale. According to another embodiment, the holding means will consist of one or more vertical stiffening ribs formed at the level of said lateral face.
L'invention a également pour objet des procedés pour munir lesdits sachets desdits moyens de maintien et de stabilisation. The invention also relates to methods for providing said sachets with said holding and stabilization means.

On se référera tout d'abord à la figure 1. We will first refer to Figure 1.
Selon ce mode de mise en oeuvre de l'invention, un sachet (1) comportant essentiellement
- deux parois latérales telles que (2)
- un fond (3) sur lequel il est appelé à reposer ;
- une zone de rigidification et de préhension (4) reliant entre elles les deux parois latérales (2) ;
- une face frontale (5) reliant également entre elles les deux parois latérales (2) ; est muni, conformement à l'invention, d'un moyen de rigidification et de stabilisation.According to this embodiment of the invention, a sachet (1) essentially comprising
- two side walls such as (2)
- a bottom (3) on which it is called to rest;
- a stiffening and gripping zone (4) connecting the two side walls (2) together;
- a front face (5) also connecting together the two side walls (2); is provided, in accordance with the invention, with a stiffening and stabilization means.
Il peut s'agir :
- d'un contrefort rigide (6)
- et/ ou d'une ou plusieurs nervures verticales (7).It could be :
- a rigid buttress (6)
- And / or one or more vertical ribs (7).
Le contrefort sera disposé préférentiellement de manière telle que sa base (6') puisse, lorsque le sachet est posé sur une surface plane, prendre appui sur ladite surface plane.The buttress will preferably be arranged in such a way that its base (6 ′) can, when the sachet is placed on a flat surface, bear on said flat surface.
11 pourra être en toute matière, par exemple en matiere synthétique, éventuellement de recyclage pour limiter le prix de revient, en carton etc..., ceci de manière non limitative. It may be of any material, for example synthetic material, possibly of recycling to limit the cost price, of cardboard, etc., this in a nonlimiting manner.
I1 pourra en outre affecter toute forme compatible avec la fonction impartie, telle que par exemple, mais non limitativement
- forme hemi-circulaire, comme représente à la figure 1 ;
- forme quadrangulaire (7), comme représenté à la figure 2 ;
- forme trapezoadale (8), eventuellement tronquée, comme représenté à la figure 3
- forme évidée (9), en fer à cheval, comme representé à la figure 4
- forme trapézoîdale (10), comme représente à la figure 5, les angles de base étant rabattus contre les parois laterales (2) pour renforcer encore la stabilisation.I1 may also affect any form compatible with the outsourced function, such as for example, but not limitatively
- semi-circular shape, as shown in Figure 1;
- quadrangular shape (7), as shown in Figure 2;
- trapezoidal shape (8), possibly truncated, as shown in Figure 3
- hollowed out shape (9), in horseshoe, as shown in figure 4
- trapezoidal shape (10), as shown in Figure 5, the base angles being folded against the side walls (2) to further enhance stabilization.
On constatera que, dans toutes les formes d'illustra- tion proposées, il existe une ligne de contact respectivement (6', 7', 8', 9' 10') entre le contrefort (6, 7, 8, 9, 10) et la surface sur laquelle repose le sachet qui en est muni. It will be noted that, in all the forms of illustration proposed, there is a contact line respectively (6 ', 7', 8 ', 9' 10 ') between the buttress (6, 7, 8, 9, 10 ) and the surface on which the bag which is provided with it rests.
De manière optionnelle, comme representé à la figure 6, on pourra prevoir que le contrefort (6), dans un souci d'économie de matiere, soit découpe dans l'élément (11 > applique dans la zone de rigidification et de prehension (4) precitée. Optionally, as shown in FIG. 6, it will be possible to provide that the buttress (6), for the sake of saving material, is cut out in the element (11> applied in the stiffening and gripping zone (4 ) above.
D'autres formes de contrefort avant pourront être utilises, qui avantageusement rempliront, outre la fonction recherchée, à savoir rigidification et stabilisation du sachet, une ou plusieurs fonctions complémentaires. Other forms of front buttress can be used, which advantageously will fulfill, in addition to the desired function, namely stiffening and stabilization of the bag, one or more complementary functions.
Ainsi il peut etre très avantageusement envisage que le contrefort coopère à la fermeture du sachet, une fois que celui-ci a été ouvert. Thus it can be very advantageously envisaged that the buttress cooperates in the closing of the bag, once it has been opened.
Dans le mode de réalisation des figures 7, 8 et 9 auxquelles on va se réferer maintenant, le contrefort est de forme générale oblongue et trapézoïdale. Il est rendu solidaire du sachet (1) par deux lignes de soudure ou de collage (13, 14) disposées l'une (13) sensiblement à la base de la face avant, l'autre (14) légèrement décalée par rapport à la partie superieure dudit contrefort (12), déterminant ainsi une zone (15) ouverte sur 3 côtés et en particulier en direction du haut du sachet ou doit être pratiquée l'ouverture de versage (16). In the embodiment of Figures 7, 8 and 9 to which we will now refer, the buttress is generally oblong and trapezoidal. It is made integral with the bag (1) by two welding or bonding lines (13, 14) arranged one (13) substantially at the base of the front face, the other (14) slightly offset from the upper part of said buttress (12), thus determining an area (15) open on 3 sides and in particular in the direction of the top of the bag where the pouring opening (16) must be made.
Cette structure de la partie supérieure du sachet est représentée, agrandie, à la figure 8. This structure of the upper part of the bag is shown, enlarged, in FIG. 8.
Pour refermer le sachet après un premier usage, la corne superieure (17) comportant l'ouverture (16) est rabattue contre le contrefort (12) et insérée entre la zone (15) et la face frontale du sachet, comme représenté à la figure 9. To close the bag after a first use, the upper horn (17) comprising the opening (16) is folded against the buttress (12) and inserted between the zone (15) and the front face of the bag, as shown in the figure 9.
Dans la variante des figures 10, 17 et 12, dont la fonction est totalement identique à la précédente, le sachet comporte un contrefort (18) muni à sa partie superieure d'un moyen (19) de fermeture et de pincement de la corne supérieure (17) du sachet. Comme représente à la figure 11 le moyen (19) se compose essentiellement de deux pattes (20, 21) sensiblement symétriques par rapport à l'axe longitudinal du contrefort (18) et cooperant avec un doigt (22) disposé entre lesdites pattes. In the variant of FIGS. 10, 17 and 12, the function of which is completely identical to the previous one, the bag has a buttress (18) provided at its upper part with means (19) for closing and pinching the upper horn. (17) of the sachet. As shown in Figure 11 the means (19) consists essentially of two legs (20, 21) substantially symmetrical with respect to the longitudinal axis of the buttress (18) and cooperating with a finger (22) disposed between said legs.
La fermeture est obtenue en rabattant la corne superieure (17) du sachet de manière à la disposer par dessus les pattes (20, 21), sous le doigt (21), où etle est maintenue par l'effet de pinçage ainsi obtenu. The closure is obtained by folding the upper horn (17) of the bag so as to arrange it over the tabs (20, 21), under the finger (21), where etle is held by the clamping effect thus obtained.
Le contrefort du type décrit ci-dessus et représente aux figures 1 à 12 pourra être rapporté sur le sachet par tout moyen, tel que soudure ou collage, à un moment quelconque du processus de fabrication et de remplissage du sachet. The buttress of the type described above and shown in Figures 1 to 12 may be attached to the bag by any means, such as welding or gluing, at any time during the process of manufacturing and filling the bag.
Par exemple, le contrefort (6, 7, 8, 9, 12, 18) pourra être rapporté par un procedé analogue à celui permettant de fixer l'élément de rigidification et de préhension (11), comme décrit à titre d'exemple dans la demande de brevet en FRANCE 83-18257 au nom de la demanderesse. For example, the buttress (6, 7, 8, 9, 12, 18) can be added by a process analogous to that making it possible to fix the stiffening and gripping element (11), as described by way of example in patent application in FRANCE 83-18257 in the name of the applicant.
Selon un second mode de mise en oeuvre, le moyen de rigidification et de stabilisation pourra consister en une ou plusieurs nervures verticales (7), déjà représentées à la figure 1. Sur cette représentation, ces nervures (7) sont utilisées conjointement à un contrefort tel que (6) du type illustre dans ce qui précède. According to a second embodiment, the stiffening and stabilization means may consist of one or more vertical ribs (7), already shown in Figure 1. In this representation, these ribs (7) are used in conjunction with a buttress such as (6) of the type illustrated in the above.
La ou les nervures (7) peuvent également contribuer seules à l'obtention du résultat recherché, à savoir la rigidification et la stabilisation du sachet. The rib (s) (7) can also alone contribute to obtaining the desired result, namely stiffening and stabilization of the sachet.
Ainsi aux figures 13 et 13 A, on a représenté un sachet (1') muni de deux nervures frontales verticales (23, 24) de ce type. Thus in Figures 13 and 13 A, there is shown a bag (1 ') provided with two vertical front ribs (23, 24) of this type.
Avantageusement, l'arête inférieure de la face frontale du sachet (7') en contact avec la surface sur lequel celui-ci est disposé sera également renforcee par une soudure (25). Advantageously, the lower edge of the front face of the bag (7 ′) in contact with the surface on which it is disposed will also be reinforced by a weld (25).
On a représente aux figures 14 et 14 B un mode de mise en oeuvre du meme type que le précédent, mais avec une seule nervure de rigidification et de stabilisation (26), éventuellement renforcee par une soudure (27) sur l'arête inférieure de la face frontale. FIGS. 14 and 14 B show an embodiment of the same type as the previous one, but with a single stiffening and stabilization rib (26), possibly reinforced by a weld (27) on the lower edge of the front face.
Les nervures (23, 24, 26) pourront être realisées, à titre d'exemple non limitatif, grâce au dispositif suivant. The ribs (23, 24, 26) can be produced, by way of nonlimiting example, using the following device.
Sur un conformateur (28) de type connu de l'homme de l'art, sur lequel un film (29) est amené à être conformé en boudin continu (30), puis à être rempli du liquide à conditionner et transformé en sachets ou coussins individuels par le biais entre autres d'une canule centrale (31), on prévoit des postes d'intervention et de conformation de la ou des nervures (23, 24, 26). On a conformator (28) of a type known to those skilled in the art, on which a film (29) is made to be shaped into a continuous rod (30), then to be filled with the liquid to be packaged and transformed into sachets or individual cushions, inter alia by means of a central cannula (31), intervention and shaping stations of the rib (s) (23, 24, 26) are provided.
On prendra l'exemple de la réalisation de deux nervures (23, 24). Take the example of making two ribs (23, 24).
Au niveau d'un premier poste (32) le film étant à ce stade prêt à être soude pour être transforme en boudin continu (30), un conformateur (33) dans lequel passe le film confère à celui-ci une forme en W. At a first station (32) the film being at this stage ready to be welded in order to be transformed into a continuous rod (30), a former (33) through which the film passes gives the latter a W shape.
Au poste (34) disposé en aval de celui-ci, on procède conjointement ou successivement
- à la soudure du film (29) pour le conformer en boudin (30), de manière classique, par une mâchoire de de soudage (35)
- à la soudure du pli en W précité au niveau de ses deux aretes (36, 37) par deux éléments de soudure (38, 39), un élément isolant (40) étant interpose pour eviter la soudure des deux arêtes (36, 37) entre elles.At the station (34) arranged downstream thereof, one proceeds jointly or successively
- to the welding of the film (29) to conform it to a flange (30), in a conventional manner, by a welding jaw (35)
- at the welding of the aforementioned W-fold at its two edges (36, 37) by two welding elements (38, 39), an insulating element (40) being interposed to avoid the welding of the two edges (36, 37 ) between them.
Enfin, un poste (41) dispose en aval est muni de deux doigts écarteurs (42, 43) qui déplient la zone conformée en W de maniere à lui conférer la structure recherchée pour former la face frontale du f-utur sachet. Finally, a station (41) arranged downstream is provided with two spacer fingers (42, 43) which unfold the zone conformed in W so as to give it the desired structure to form the front face of the f-utur sachet.
Bien entendu l'invention ne se limite pas aux seuls modes de mise en oeuvre decrits. Elle en embrasse toutes les variantes, dans les limites des connaissances de l'homme de l'art. Of course, the invention is not limited to the modes of implementation described. It embraces all variants thereof, within the limits of the knowledge of a person skilled in the art.
