Description

La présente invention concerne un sac filtrant pour rétention de particules physiques, dont une application constitue un sac à poussière pour aspirateur, comportant une partie perméable aux fluides, essentiellement gazeux, comme l'air par exemple, présentant au moins une ouverture destinée à permettre l'introduction d'un conduit par lequel le fluide chargé de particules s'écoule dans le réceptacle.The present invention relates to a filter bag for retaining physical particles, one application of which constitutes a dust bag for a vacuum cleaner, comprising a part permeable to fluids, essentially gaseous, such as air for example, having at least one opening intended to allow the introduction of a conduit through which the fluid charged with particles flows into the receptacle.

Les sacs à poussière connus sont généralement constitués d'une partie perméable à l'air, attenante à une embase de fixation en carton, ou matière similaire, munie d'une ouverture d'arrivée pour l'air chargé de poussières, cette embase servant de support au sac à poussière lorsqu'il est mis en place dans l'aspirateur.Known dust bags generally consist of an air-permeable part, adjoining a cardboard fixing base, or similar material, provided with an inlet opening for the air charged with dust, this base serving support for the dust bag when it is placed in the vacuum cleaner.

Cette embase complique considérablement la fabrication du sac à poussière, ce qui en accroît le coût du fait de la nécessité soit, d'une main d'oeuvre plus importante, soit d'investissements en matériels spéciaux, sans parler de la quantité de matière supplémentaire qui vient grever les coûts de transport.This base considerably complicates the manufacture of the dust bag, which increases the cost due to the need either for a larger workforce or investment in special materials, not to mention the amount of additional material which adds to the transport costs.

D'autres systèmes ne présentent pas cette embase attenante au sac, mais sont, soit d'une mise en place complexe, hasardeuse ou malaisée, soit ne permettent pas d'obtenir une étanchéité suffisante aux orifices d'introduction du conduit d'arrivée d'air, ou à ceux nécessités pour la fixation ou la mise en place d'un dispositif amovible de fixation ou similaire, soit encore compliquent notablement l'appareil devant les employer, ainsi que leur manipulation.Other systems do not have this base adjoining the bag, but are either of a complex, hazardous or awkward installation, or do not make it possible to obtain a sufficient seal at the orifices for introducing the inlet conduit of air, or to those necessary for the fixing or the installation of a removable fixing device or the like, either further complicates notably the apparatus before employing them, as well as their handling.

La présente invention remédie à ces inconvénients, en permettant de réaliser et d'employer un sac à poussière simple, d'une fabrication aisée et économique, qui soit léger, pratique à utiliser et remplisse au mieux les fonctions auxquelles il est destiné.The present invention overcomes these drawbacks by making it possible to use and use a simple dust bag, of an easy and economical manufacture, which is light, practical to use and best fulfills the functions for which it is intended.

Pour atteindre les buts ci-dessus, l'invention se caractérise en ce que :

  • - l'embase rigide est constituée par une pièce indépendante formant une partie de liaison avec un sac et une partie d'adaptation dans un réceptacle, au moins la partie de liaison étant percée d'un trou de passage d'un conduit d'amenée d'air,
  • - le sac comporte, au moins localement, deux couches au moins en partie superposées et séparées l'une de l'autre, délimitant un intervalle accessible par une ouverture apparaissant au niveau de la couche extérieure et correspondant à la largeur de la partie de liaison de l'embase, - lesdites couches présentant deux trous coincidant entre eux et destinés à coincider avec celui de l'embase après insertion de la partie de liaison dans l'intervalle par l'ouverture,
  • - et un dispositif d'étanchéité est prévu au niveau de la partie de liaison insérée dans l'intervalle pour coopérer avec le conduit.
To achieve the above aims, the invention is characterized in that:
  • - the rigid base consists of an independent part forming a connection part with a bag and an adaptation part in a receptacle, at least the connection part being pierced with a passage hole of a supply conduit air,
  • - the bag comprises, at least locally, two layers at least partly superimposed and separated from each other, delimiting an accessible interval by an opening appearing at the level of the external layer and corresponding to the width of the connecting part of the base, - said layers having two holes coinciding with each other and intended to coincide with that of the base after insertion of the connecting part in the interval through the opening,
  • - And a sealing device is provided at the connecting part inserted in the interval to cooperate with the conduit.

La fig. 1 représente une première forme de réalisation d'un sac selon l'invention. Un tel sac, par exemple réalisé en papier filtrant, peut être du type en forme d'enveloppe possédant deux extrémités fermées. L'enveloppe est localement du type à deux épaisseurs et comporte ainsi, dans une des parties des parois, une couche extérieure 2 avec une découpe 3 et une ouverture 6, par exemple circulaire. Dans la même partie locale, l'enveloppe possède une seconde couche 4, dite intérieure, présentant une ouverture 5 qui est placée en coïncidence avec l'ouverture 6 de la couche 2. Les ouvertures 5 et 6 possèdent des dimensions permettant le passage d'un conduit 8 de circulation d'un air chargé de poussières.Fig. 1 shows a first embodiment of a bag according to the invention. Such a bag, for example made of filter paper, can be of the envelope-shaped type having two closed ends. The envelope is locally of the two-thickness type and thus comprises, in one of the parts of the walls, an outer layer 2 with a cutout 3 and an opening 6, for example circular. In the same local part, the envelope has a second layer 4, called the inner layer, having an opening 5 which is placed in coincidence with the opening 6 of the layer 2. The openings 5 and 6 have dimensions allowing the passage of a duct 8 for circulation of an air charged with dust.

Les fig. 2 et 3 montrent, à plus grande échelle, que selon l'invention, le sac décrit ci-dessus est complété par une embase 11 en un matériau rigide, tel qu'en carton compact, en matière plastique, etc ... L'embase 11 comporte deux parties 12 et 16 s'étendant, selon l'exemple illustré, dans la même direction, de façon sensiblement parallèle à partir d'un fond commun 17. La partie 12, dite de liaison avec le sac, présente une largeur légèrement inférieure à la longueur de la découpe 3, de manière à pouvoir être insérée dans cette dernière et être disposée dans l'intervalle entre les couches 2 et 4. La partie 16, dite d'adaptation, présente, de préférence, une longueur inférieure à la partie 12 et offre une conformation complémentaire aux moyens de fixation qui sont prévus, sur ou dans un réceptacle du sac, tel que le compartiment d'un aspirateur.Figs. 2 and 3 show, on a larger scale, that according to the invention, the bag described above is completed by a base 11 made of a rigid material, such as compact cardboard, plastic material, etc. base 11 has two parts 12 and 16 extending, according to the example illustrated, in the same direction, substantially parallel from a common bottom 17. Part 12, called the connection with the bag, has a width slightly less than the length of the cutout 3, so that it can be inserted into the latter and be arranged in the interval between the layers 2 and 4. The part 16, called adaptation, preferably has a shorter length to part 12 and offers a complementary conformation to the fixing means which are provided, on or in a receptacle of the bag, such as the compartment of a vacuum cleaner.

La partie'12 présente une ouverture 13 munie d'un dispositif d'étanchéité 14 qui peut être, de façon connue, une lèvre en matière déformable élastiquement de faible épaisseur. La garniture 14 peut être rapportée sur la face extérieure de la partie 12 ou sur la face intérieure comme représenté en traits mixtes à la fig. 3. La partie 16 présente une ouverture 15 coaxiale à l'ouverture 13. Les ouvertures 13 et 15 sont prévues pour permettre le passage du conduit 8 et la garniture d'étanchéité 14 est prévue pour entourer, avec déformation élastique, un tel conduit.The part 12 has an opening 13 provided with a sealing device 14 which may be, in known manner, a lip of elastically deformable material of small thickness. The lining 14 can be attached to the outer face of the part 12 or to the inner face as shown in phantom in FIG. 3. The part 16 has an opening 15 coaxial with the opening 13. The openings 13 and 15 are provided to allow passage of the conduit 8 and the seal 14 is provided to surround, with elastic deformation, such a conduit.

Selon l'invention, l'adaptation des moyens décrits ci-dessus s'effectue (fig. 4) en assurant l'insertion de la partie 12 de l'embase 11 dans la découpe 3. La partie 12 est ainsi insérée dans l'intervalle entre les couches 2 et 4, jusque dans une position dans laquelle les ouvertures 13 et 15 coincident avec les ouvertures 5 et 6.According to the invention, the means described above are adapted (fig. 4) by ensuring the insertion of part 12 of the base 11 in the cutout 3. Part 12 is thus inserted into the interval between layers 2 and 4, up to a position in which the openings 13 and 15 coincide with the openings 5 and 6.

Le sac 1 équipé comme dit ci-dessus peut être monté disposé ou placé dans le réceptacle ou le compartiment prévu pour le recevoir, par exemple, d'un aspirateur. La partie 16 est adaptée sur les moyens de fixation qui sont prévus à cet effet, par exemple autour d'un orifice de passage du compartiment à travers lequel fait saillie le conduit 8. Lors de la fermeture du compartiment de l'aspirateur, le conduit 8 traverse, simultanément, au moins les ouvertures 15 et 6 pour coopérer avec le dispositif 14 qui entoure le conduit 8 à la manière d'une lèvre. Il en résulte une étanchéité s'opposant à tout refoulement vers l'extérieur du fluide ou de l'air chargé de poussières introduit dans ledit sac.The bag 1 equipped as said above can be mounted arranged or placed in the receptacle or the compartment intended to receive it, for example, from a vacuum cleaner. Part 16 is adapted to the fastening means which are provided for this purpose, for example around a passage opening in the compartment through which the duct 8 projects. the vacuum cleaner, the conduit 8 passes, simultaneously, at least the openings 15 and 6 to cooperate with the device 14 which surrounds the conduit 8 in the manner of a lip. This results in a seal opposing any discharge to the outside of the fluid or air loaded with dust introduced into said bag.

La fig. 4 montre que le gonflement du sac 1, sous l'effet de l'introduction d'un flux d'air chargé de particules, a pour effet de plaquer la couche ou épaisseur 4 sous la partie 12 et la garniture d'étanchéité 14 autour du tube 8. Ceci permet, par conséquent, de réaliser une étanchéité d'adaptation entre l'ouverture 5 et le conduit ou tube 8.Fig. 4 shows that the swelling of the bag 1, under the effect of the introduction of a flow of air loaded with particles, has the effect of pressing the layer or thickness 4 under the part 12 and the seal 14 around of the tube 8. This therefore makes it possible to produce an adaptation seal between the opening 5 and the conduit or tube 8.

Outre cette première fonction, il y a lieu de noter que la partie 12 représente, pour la couche ou épaisseur de paroi 4, un support et une butée s'opposant à toute tendance à une défor- - mation exagérée de ladite paroi dans une zone où cette dernière ne rencontrerait pas d'appui suffisant par les parois délimitant le compartiment.In addition to this primary function, it should be noted that the portion 12 is, for the layer thickness or wall 4, a support and an abutment opposing any tendency to deform - mation exaggerated said wall in a zone where the latter would not meet sufficient support by the walls delimiting the compartment.

Une troisième fonction de la disposition selon l'invention réside dans le fait que la partie 16 constitue un élément d'adaptation et de support amovibles du sac sur les moyens de fixation prévus à cet effet dans le compartiment de réception.A third function of the arrangement according to the invention lies in the fact that the part 16 constitutes a removable adaptation and support element for the bag on the fixing means provided for this purpose in the receiving compartment.

Lorsque le sac est rempli de déchets, poussières, etc ... qui ont été retenus, le compartiment peut être ouvert pour permettre le dégagement du conduit 8, soit automatiquement, soit par extraction manuelle. Ce dégagement permet de libérer l'embase 11 du compartiment et d'extraire le sac 1 plein. Le regarnissage de l'aspirateur s'effectue par le montage d'un sac neuf au niveau de l'ouverture 3 duquel l'embase 11, dégagée préalablement du sac utilisé, est réinsérée pour reconstituer les moyens coopérant entre eux afin d'assumer les fonctions décrites ci-dessus.When the bag is filled with waste, dust, etc. which have been retained, the compartment can be opened to allow the release of the conduit 8, either automatically or by manual extraction. This release frees the base 11 from the compartment and extracts the full bag 1. The relining of the vacuum cleaner is carried out by mounting a new bag at the opening 3, from which the base 11, previously released from the bag used, is reinserted to reconstitute the means cooperating with each other in order to assume the functions described above.

Selon l'invention, par conséquent, l'embase 11 est rendue indépendante du sac et peut être enlevée d'un sac plein pour rééquiper un sac vide. Ceci permet de réaliser une embase 11 particulièrement soignée et de la munir, en particulier, de tous les aménagements adaptables, d'une part, pour la liaison avec le sac puis de l'ensemble ainsi constitué sur l'appareil d'aspiration, d'autre part, pour une étanchéité particulièrement soignée par rapport au conduit d'arrivée de l'air chargé de poussières.According to the invention, therefore, the base 11 is made independent of the bag and can be removed from a full bag to re-equip an empty bag. This makes it possible to produce a particularly neat base 11 and to provide it, in particular, with all the adaptable arrangements, on the one hand, for connection with the bag and then of the assembly thus formed on the suction device, on the other hand, for a particularly careful sealing in relation to the inlet duct of the air charged with dust.

Il en résulte un gain notable de fabrication et de coût de matière première des sacs perdus pour aspirateurs et la possibilité de rationnaliser la fabrication de tels sacs en vue d'obtenir des produits d'un prix de revient nettement amélioré, puisque les opérations actuelles de garnissage de l'embase sont longues et onéreuses.This results in a significant gain in manufacturing and raw material cost of lost bags for vacuum cleaners and the possibility of rationalizing the manufacturing of such bags in order to obtain products of a significantly improved cost price, since the current operations of lining of the base are long and expensive.

Un autre avantage réside dans le fait qu'au moyen d'une telle solution, il n'est plus nécessaire de prévoir un conduit 8 portant lui-même un dispositif d'étanchéité comme cela est parfois le cas dans certaines dispositions actuelles. A cet égard, il y a lieu de considérer que la garniture 14 pourrait être aussi rapportée directement sur le sac.Another advantage lies in the fact that by means of such a solution, it is no longer necessary to provide a conduit 8 itself carrying a sealing device as is sometimes the case in certain current arrangements. In this regard, it should be considered that the lining 14 could also be attached directly to the bag.

La fig. 5 montre une variante de réalisation selon laquelle le sac, selon l'invention, désigné dans son ensemble par la référence 100, possède, localement, sur la face extérieure de sa paroi périphérique et, par exemple, sur la partie référencée 102, une bande 103 pouvant être rapportée par collage ou tout autre moyen au niveau de deux plages latérales 104. La bande 103 est, par conséquent, libre par rapport à la partie 102 qu'elle recouvre et délimite, avec cette dernière, l'intervalle existant dans l'exemple de'réalisation précédent entre les couches 2 et 4. La partie 102, recouverte par la bande 103, possède une ouverture 105 en coincidence de laquelle est placée une ouverture 106 de la bande 103.Fig. 5 shows an alternative embodiment according to which the bag according to the invention, designated as a whole by the reference 100, has locally on the outer face of its peripheral wall and, for example, on the part referenced 102, a strip 103 can be attached by gluing or any other means at two lateral areas 104. The strip 103 is, therefore, free with respect to the part 102 which it covers and delimits, with the latter, the interval existing in the 'example de'réalisation between layers 2 and 4. The part 102, covered by the strip 103, has an opening 105 coincident with which is placed an opening 106 of the strip 103.

Une telle disposition permet, par conséquent, avec l'un des bords de la bande 103, par exemple le bord 107, de délimiter, avec la partie 102 recouverte, une ouverture 108 permettant l'introduction, dans le sens de la flèche f,, d'une embase 11 du type décrit en référence à la fig. 2.Such an arrangement therefore makes it possible, with one of the edges of the strip 103, for example the edge 107, to delimit, with the part 102 covered, an opening 108 allowing the introduction, in the direction of the arrow f, , a base 11 of the type described with reference to FIG. 2.

La forme de réalisation illustrée par la fig. 5 permet de simplifier l'exécution du sac 100 et d'abaisser encore le prix de revient de ce dernier, tout en procurant un produit répondant aux caractéristiques de maintien et d'étanchéité au niveau du conduit 8 inséré.The embodiment illustrated in FIG. 5 makes it possible to simplify the execution of the bag 100 and to further lower the cost price of the latter, while providing a product which meets the characteristics of holding and sealing at the level of the conduit 8 inserted.

La fig. 5 montre que la liaison entre la bande 103 et la partie 102 peut faire intervenir, par exemple, un collage au niveau d'un troisième bord 109, tel que celui représenté en traits mixtes. Une telle liaison permet d'améliorer encore l'étanchéité établie entre la partie 102 et le segment du conduit 8 la traversant.Fig. 5 shows that the connection between the strip 103 and the part 102 may involve, for example, bonding at a third edge 109, such as that shown in dashed lines. Such a connection makes it possible to further improve the seal established between the part 102 and the segment of the conduit 8 passing through it.

La fig. 6 correspond à une variante de réalisation consistant à assurer l'adaptation de la bande 103 par l'intermédiaire de plages latérales 104a qui sont retournées vers l'intérieur. Ceci permet de conférer, à l'intervalle qui est ainsi ménagé pour la réception de la partie 12 de l'embase 11, une épaisseur utile compatible avec la réception et le glissement de ladite partie 12.Fig. 6 corresponds to an alternative embodiment consisting in ensuring the adaptation of the strip 103 by means of lateral pads 104a which are turned inward. This makes it possible to confer, at the interval which is thus provided for the reception of the part 12 of the base 11, a useful thickness compatible with the reception and the sliding of said part 12.

La fig. 7 montre une réalisation préférée selon laquelle- la bande 103 est réalisée sous la forme d'un segment de tronçon ou d'enveloppe tubulaire 103a, mis à plat par pliage, par exemple le long de deux génératrices diamétralement opposées, et adapté par l'un des plats sur la partie 102 du sac 100.Fig. 7 shows a preferred embodiment according to which the strip 103 is produced in the form of a segment of tubular section or casing 103a, laid flat by folding, for example along two generators diametrically opposed, and adapted by the one of the dishes on part 102 of bag 100.

Le segment tubulaire 103a est rapporté notamment par collage sur la face extérieure de la partie 102 qui représente la couche interne. Le plat supérieur du segment 103a constitue la couche supérieure. Les deux plats du segment 103a délimitent l'intervalle dans lequel peut être inséré, par glissement dans le sens de la flèche f1, la partie 12 de l'embase 11. L'une ou l'autre des sections transversales ouvertes du segment 103a représente une ouverture 108 assumant la fonction de la découpe 3.The tubular segment 103a is attached in particular by bonding to the outer face of the part 102 which represents the inner layer. The upper plate of segment 103a constitutes the upper layer. The two plates of the segment 103a delimit the interval into which the part 12 of the base 11 can be inserted, by sliding in the direction of the arrow f 1. One or the other of the open cross sections of the segment 103a represents an opening 108 assuming the function of the cutout 3.

Le plat supérieur du segment 103a présente une ouverture 106 alors que le plat inférieur est pourvu d'une ouverture 105 pour l'engagement du conduit 8. L'ouverture 105 est placée, en position d'utilisation, en regard d'une ouverture 5 ménagée dans la partie 102 du sac.The upper plate of the segment 103a has an opening 106 while the lower plate is provided with an opening 105 for the engagement of the conduit 8. The opening 105 is placed, in the position of use, opposite an opening 5 formed in part 102 of the bag.

Une telle réalisation facilite la fabrication du sac et offre les avantages de simplicité, efficacité et facilité de mise en oeuvre et utilisation.Such an embodiment facilitates the manufacture of the bag and offers the advantages of simplicity, efficiency and ease of implementation and use.

Le segment 103a peut être réalisé en toute matière appropriée. Il apparait préférable cependant de retenir une matière plastique, de faible épaisseur, telle que le polyéthylène. En effet, comme cela apparait à la fig. 8, il devient alors possible de réaliser l'ouverture 105 selon un diamètre légèrement inférieur à celui du conduit 8. Ainsi, lors de la coopération, le plat inférieur forme, par sa partie bordant l'ouverture 105, une sorte de lèvre périphérique 105a, entourant le conduit 8 qui peut être juste engagé ou traversant par rapport à ladite ouverture. La lèvre 105a assume ainsi une fonction de garniture d'étanchéité en remplacement du dispositif 14 qui n'a plus à être prévu.Segment 103a can be made of any material appropriate. It appears preferable, however, to retain a plastic material, of small thickness, such as polyethylene. Indeed, as it appears in fig. 8, it then becomes possible to make the opening 105 according to a diameter slightly smaller than that of the conduit 8. Thus, during the cooperation, the lower plate forms, by its part bordering the opening 105, a sort of peripheral lip 105a , surrounding the conduit 8 which can be just engaged or passing through with respect to said opening. The lip 105a thus assumes a function of a seal in replacement of the device 14 which no longer has to be provided.

La fig. 9 montre une autre variante de réalisation selon laquelle la délimitation de l'intervalle et de l'ouverture d'engagement de la partie 12 sont obtenus en utilisant les rives, lisières ou bordures longitudinales 110 et 111 d'une bande de matière première- filtrante repliée sur elle-même pour former une enveloppe tutulaire 112. Une telle enveloppe représente, après sectionnement à longueur voulue, un sac dont les extrémités transversales sont fermées par pliage et/ou collage par exemple. Dans un tel cas, la partie 110 recouvrante et la partie 111 recouverte définissent une plage de recouvrement qui est au moins égale, sinon supérieure, à la longueur de la partie 12. En outre, les bordures 110 et 111 sont réunies entre elles par tout moyen approprié, notamment par collage, tel que cela apparait sous la forme de hachures interrompues aux dessins, de manière à laisser subsister, tel que défini par un pointillé, un logement 113 s'assimilant à l'intervalle des exemples précédents. Le logement 113 est accessible par le bord correspondant longitudinal 110a de la partie recouvrante 110, lequel n'est pas rendu solidaire de la surface extérieure de la partie recouverte 111.Fig. 9 shows another alternative embodiment according to which the delimitation of the interval and of the engagement opening of the part 12 are obtained by using the edges, selvedges or longitudinal edges 110 and 111 of a strip of raw filter material. folded back on itself to form a tutular envelope 112. Such an envelope represents, after sectioning to the desired length, a bag whose transverse ends are closed by folding and / or gluing for example. In such a case, the covering part 110 and the covered part 111 define a covering range which is at least equal, if not greater, to the length of the part 12. In addition, the edges 110 and 111 are joined together by all appropriate means, in particular by gluing, as it appears in the form of hatches interrupted in the drawings, so as to leave subsist, as defined by a dotted line, a housing 113 assimilating to the interval of the preceding examples. The housing 113 is accessible by the corresponding longitudinal edge 110a of the covering part 110, which is not made integral with the external surface of the covered part 111.

Ainsi, dans cet exemple de réalisation, une embase 11 peut être introduite par la partie 12 dans le sens de la flèche fl,, figurée au dessin. Les ouvertures 13 et 15 des parties 12 et 16 sont ainsi amenées en coïncidence avec des ouvertures 114 et 115 qui sont ménagées à cet effet dans les parties 110 et 111.Thus, in this exemplary embodiment, a base 11 can be introduced by the part 12 in the direction of the arrow f l ,, shown in the drawing. The openings 13 and 15 of the parts 12 and 16 are thus brought into coincidence with the openings 114 and 115 which are provided for this purpose in the parts 110 and 111.

La fig. 10 illustre une variante de réalisation selon laquelle il peut être prévu de conférer à l'embase 11 une longueur suffisante de manière que le fond 17 de liaison entre les parties 12 et 16 soit, après la mise en place et insertion convenable dans l'intervalle de réception, disposé à proximité de l'un des bords ou d'un pli présenté par le sac, tel que celui désigné par la référence 116 à la fig. 8. La superposition du fond 17 et du bord 116 peut être mise à profit pour assurer un maintien et une liaison ferme et résistante, notamment par l'intermédiaire d'une pince élastique 117.Fig. 10 illustrates an alternative embodiment according to which it can be provided to give the base 11 a sufficient length so that the bottom 17 of connection between the parts 12 and 16 is, after the establishment and suitable insertion in the reception interval, placed near one of the edges or a fold presented by the bag, such as that designated by the reference 116 in FIG. 8. The superposition of the bottom 17 and the edge 116 can be used to ensure a firm and resistant connection and connection, in particular by means of an elastic clamp 117.

L'embase 11 est ainsi immobilisée dans une position ferme pour coopérer avec les moyens de fixation du sac à l'intérieur du compartiment, sans solliciter, pour cette fonction, la pièce 103-103a ou 110.The base 11 is thus immobilized in a firm position to cooperate with the means for fixing the bag inside the compartment, without requesting, for this function, the part 103-103a or 110.

La fig. 10 montre, en traits mixtes, qu'il peut être prévu de faire comporter au fond 17 une barrette 118 possédant, par exemple, une longueur sensiblement égale à la largeur du sac. Il devient ainsi possible d'utiliser simultanément la barrette 118 et la pince 117 pour affermir la position de l'embase sur le sac et pour réaliser une fermeture de ce dernier lorsque le bord 116 représente, par exemple, la gueule ouverte du sac. Un tel moyen permet de diminuer notablement le coût de fabrication d'un sac puisqu'une seule opération de fermeture transversale est alors nécessaire, la seconde fermeture étant réalisée par l'utilisateur au moment de la mise en place.Fig. 10 shows, in phantom, that it can be provided to have at the bottom 17 a bar 118 having, for example, a length substantially equal to the width of the bag. It thus becomes possible to simultaneously use the bar 118 and the clamp 117 to strengthen the position of the base on the bag and to make a closure of the latter when the edge 116 represents, for example, the open mouth of the bag. Such a means makes it possible to significantly reduce the cost of manufacturing a bag since a single transverse closing operation is then necessary, the second closing being carried out by the user at the time of implementation.

La fig. 11 illustre une autre variante de réalisation selon laquelle une des parties de l'embase 11, par exemple la partie 12, forme directement ou comporte associée à elle-même une pince articulée 119 destinée à pincer le bord 116. Une réalisation équivalente au plan technique est . représentée à la fig. 12. Selon cette dernière, la pince 119 est formée par une partie 120 articulée sur une barrette 118a qui est formée par l'embase 11 à partir du fond 17 et dans le plan de la partie 12.Fig. 11 illustrates another alternative embodiment according to which one of the parts of the base 11, for example the part 12, directly forms or comprises associated with itself an articulated clamp 119 intended to clamp the edge 116. An embodiment equivalent to the technical plan East . shown in fig. 12. According to the latter, the clamp 119 is formed by a part 120 articulated on a bar 118a which is formed by the base 11 from the bottom 17 and in the plane of the part 12.

La fig. 13 montre que l'embase 11 peut aussi comporter une partie 12a de liaison avec le sac et une partie 16a d'adaptation s'étendant dans le même plan. Dans un tel cas, seule la partie 12a présente alors une ouverture 13 éventuellement bordée par une garniture 14. Une telle forme d'exécution peut être rendue nécessaire selon la structure des moyens de fixation. La partie 16a peut aussi être de conformation différente de la partie 12a, comme illustré en traits mixtes. De même, il peut être prévu de conférer une orientation relative différente aux deux parties et, par exemple, une disposition à angle droit.Fig. 13 shows that the base 11 can also include a part 12a for connection with the bag and an adaptation part 16a extending in the same plane. In such a case, only the part 12a then has an opening 13 possibly bordered by a packing 14. Such an embodiment may be made necessary depending on the structure of the fixing means. The part 16a can also be of different conformation from the part 12a, as illustrated in phantom. Likewise, provision may be made to impart a different relative orientation to the two parts and, for example, a right angle arrangement.

L'invention n'est pas limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown, since various modifications can be made thereto without departing from its scope.
