Description

La présente invention concerne le domaine des sachets comprenant des profilés de fermeture complémentaires actionnés respectivement à l'ouverture et à la fermeture par un curseur.The present invention relates to the field of sachets comprising complementary closure profiles actuated respectively on opening and closing by a cursor.

Ces sachets ont déjà rendu de grands services. En effet, les curseurs facilitent l'ouverture et la fermeture des sachets, de sorte que leur présence est fortement appréciée par les personnes âgées ou malvoyantes.These sachets have already rendered great services. Indeed, the sliders facilitate the opening and closing of the bags, so that their presence is highly appreciated by the elderly or visually impaired.

Par le passé, on s'est trouvé confronté à un défaut d'étanchéité de ces sachets. En particulier, la plupart de ces sachets ne présentait pas une totale étanchéité en position de fermeture des profilés. Ce défaut d'étanchéité était dû au fait que les profilés restent séparés en avant du curseur.In the past, we have been faced with a lack of tightness of these bags. In particular, most of these bags did not have a complete seal in the closed position of the profiles. This leakage was due to the fact that the profiles remain separated in front of the cursor.

Or, une parfaite étanchéité est demandée dans de nombreuses applications notamment, mais non limitativement, pour des sachets utilisés pour la congélation de produits alimentaires.However, a perfect seal is required in many applications including, but not limited to, bags used for freezing food products.

On décrit dans le document WO-A-99/65353 une structure de sachet qui permet de palier à ce défaut d'étanchéité.We describe in the document WO-A-99/65353 a bag structure that makes it possible to compensate for this leakage.

Ainsi, dans un mode de réalisation particulier, on décrit un sachet qui comporte :

  • deux feuilles généralement parallèles formant ses parois principales,
  • des profilés de fermeture complémentaires fixés respectivement sur ces feuilles,
  • un curseur pour actionner les profilés à la fermeture et à l'ouverture, ce curseur comprenant des flancs dont la surface interne de chacun porte un bossage dirigé vers le flanc opposé, de sorte que les feuilles formant les parois principales convergent l'une vers l'autre, desdits profilés vers lesdits bossages.
Thus, in a particular embodiment, a bag is described which comprises:
  • two generally parallel leaves forming its main walls,
  • complementary closure profiles respectively fixed on these sheets,
  • a slider for actuating the profiles at closure and opening, this slider comprising flanks whose inner surface of each carries a boss directed towards the opposite side, so that the sheets forming the main walls converge towards each other; other, said profiles to said bosses.

Le problème d'étanchéité selon le document précité est résolu par le fait que parallèlement aux profilés, entre les feuilles et au niveau de l'embouchure du sachet, sont prévus des moyens additionnels en relief disposés sur l'intérieur des profilés de fermeture, conçus pour assurer l'étanchéité en formant barrage entre les feuilles en position de fermeture du sachet, ces moyens additionnels étant adaptés pour être sollicités vers leur position d'étanchéité par le curseur lorsque celui-ci est déplacé vers la position de fermeture du sachet.The sealing problem according to the aforementioned document is solved by the fact that parallel to the profiles, between the sheets and at the mouth of the bag, there are provided additional means in relief arranged on the inside of the closure profiles, designed to ensure sealing by forming a barrier between the sheets in the closed position of the bag, these additional means being adapted to be biased towards their sealing position by the slider when it is moved to the closed position of the bag.

Par conséquent, l'étanchéité relative donnée par les profilés complémentaires est complétée par celle assurée par les moyens additionnels en relief.Therefore, the relative sealing given by the complementary profiles is completed by that provided by the additional relief means.

Une telle structure donne généralement satisfaction. Toutefois, elle est perfectible dans la mesure où il est nécessaire de s'assurer du bon positionnement du curseur par rapport aux moyens additionnels en relief, de manière à s'assurer du pinçage des feuilles à une distance permettant le bon contact de ces moyens additionnels.Such a structure generally gives satisfaction. However, it is perfectible insofar as it is necessary to ensure the correct positioning of the cursor with respect to the additional means in relief, so as to ensure the pinching of the sheets at a distance allowing the good contact of these additional means .

En d'autres termes, il arrive des situations dans lesquelles l'une ou l'autre des deux feuilles du sachet subit une légère translation dans une direction perpendiculaire à l'axe de déglacement du curseur, de sorte que les moyens additionnels précités ne se trouvent plus en face de l'autre. On comprend aisément qu'il en résulte alors un défaut d'étanchéité.In other words, situations arise in which one or the other of the two sheets of the bag undergoes a slight translation in a direction perpendicular to the axis of the cursor, so that the additional means mentioned above do not occur. find more in front of each other. It is easy to understand that this then results in a leakage.

Même en l'absence desdits moyens additionnels, cette légère translation pose problème (voir le document US 2004/252916 A1 ).Even in the absence of said additional means, this slight translation is problematic (see document US 2004/252916 A1 ).

La présente invention vise donc à résoudre cette difficulté.The present invention therefore aims to solve this problem.

Un but secondaire de l'invention est de parvenir à cette fin, sans modifier la structure générale du sachet précité.A secondary object of the invention is to achieve this end, without changing the general structure of the aforementioned bag.

L'invention concerne donc un sachet comportant :

  • deux feuilles généralement parallèles formant ses parois principales ;
  • des profilés de fermeture complémentaires fixés respectivement sur ces feuilles ;
  • un curseur pour actionner les profilés à la fermeture et à l'ouverture, ce curseur comprenant des flancs dont la surface interne de chacun porte un bossage dirigé vers le flanc opposé, de sorte que les feuilles formant les parois principales convergent l'une vers l'autre, desdits profilés vers lesdits bossages ;
The invention therefore relates to a bag comprising:
  • two generally parallel leaves forming its main walls;
  • complementary closure profiles respectively fixed on these sheets;
  • a slider for actuating the profiles at closure and opening, this slider comprising flanks whose inner surface of each carries a boss directed towards the opposite side, so that the sheets forming the main walls converge towards each other; another, said profiles to said bosses;

Selon l'invention, lesdites feuilles comportent sur leurs faces externes et à l'extérieur dudit curseur, des moyens de butée aptes à immobiliser lesdites feuilles relativement audit curseur selon une direction généralement perpendiculaire à l'axe de déplacement du curseur.According to the invention, said sheets have on their outer faces and outside said slider, abutment means adapted to immobilize said sheets relative to said slider in a direction generally perpendicular to the axis of movement of the slider.

Grâce à ces moyens de butée, on opère un bon positionnement des feuilles et du curseur de manière à réaliser un bon pinçage des feuilles.With these abutment means, it operates a good positioning of the sheets and the slider so as to achieve a good pinching of the sheets.

Selon d'autres caractéristiques avantageuses mais non limitatives ;

  • parallèlement auxdits profilés, entre lesdites feuilles et au niveau de l'embouchure du sachet, des moyens additionnels en relief sont disposés sur l'intérieur des profilés de fermeture, conçus pour assurer l'étanchéité en formant barrage entre les feuilles en position de fermeture du sachet, ces moyens additionnels étant adaptés pour être sollicités vers leur position d'étanchéité par le curseur lorsque celui-ci est déplacé vers la position de fermeture du sachet, et les moyens de butée se situent au voisinage desdits bossages ;
  • le sachet comporte des moyens de butée additionnels situés sur lesdites feuilles, à l'intérieur dudit curseur, c'est-à-dire du côté de son espace interne ;
  • lesdits moyens de butée sont constitués d'un bourrelet qui forme saillie à la surface de chacune desdites feuilles et qui s'étend parallèlement à l'axe de déplacement du curseur ;
  • ledit bourrelet est continu ;
  • ledit bourrelet est discontinu, c'est à dire formé d'une série de tronçons, le plus grand intervalle entre deux tronçons voisins étant inférieur à la dimension longitudinale dudit curseur ;
  • lesdits moyens de butée viennent de matière avec lesdites feuilles ;
  • lesdits moyens de butée sont des éléments rapportés auxdites feuilles.
According to other advantageous but non-limiting characteristics;
  • parallel to said profiles, between said sheets and at the mouth of the bag, additional means in relief are arranged on the inside of the closure profiles, designed to ensure sealing by forming a barrier between the sheets in the closed position of the bag, these additional means being adapted to be biased towards their sealing position by the slider when it is moved towards the closed position of the bag, and the abutment means are located in the vicinity of said bosses;
  • the bag comprises additional stop means located on said sheets, inside said cursor, that is to say on the side of its internal space;
  • said abutment means consist of a bead which protrudes from the surface of each of said sheets and which extends parallel to the axis of movement of the slider;

  • said abutment means are made of material with said sheets;
  • said abutment means are elements attached to said sheets.

D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre de certains modes de réalisations préférées.Other features and advantages of the present invention will appear on reading the following detailed description of some preferred embodiments.

Cette description sera faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue schématique en coupe d'une forme de réalisation du sachet de l'invention ;
  • les figures 2 et 3 sont des vues de détail et agrandies de la structure de sachet de la figure 1 ;
  • les figures 4, 5 et 6 sont des vues partielles de face d'un sachet conforme à l'invention, illustrant plusieurs formes de réalisations des moyens de butée.
This description will be made with reference to the appended drawings in which:
  • the figure 1 is a schematic sectional view of an embodiment of the pouch of the invention;
  • the Figures 2 and 3 are detailed and enlarged views of the pouch structure of the figure 1 ;
  • the Figures 4, 5 and 6 are partial front views of a bag according to the invention, illustrating several embodiments of the abutment means.

Le sachet représenté à la figure 1 a une structure généralement connue du document WO-A-99/65353 qui a été commenté plus haut.The bag shown in figure 1 has a generally known structure of the document WO-A-99/65353 which has been commented on above.

Ce sachet 1 comporte une embouchure 10 et un fond 11. Il est constitué de deux feuilles principales en matière plastique, référencées 12 et 13.This bag 1 has a mouth 10 and a bottom 11. It consists of two main sheets of plastic, referenced 12 and 13.

Ces feuilles sont reliées entre-elles au niveau du fond 11. Dans le mode de réalisation représenté ici, les deux feuilles sont solidaires dès l'origine. Toutefois, dans une forme de réalisation non représentée, ces deux feuilles pourraient être initialement séparées, puis superposées et fixées l'une à l'autre au moment de la fabrication du sachet.These sheets are connected to each other at the bottom 11. In the embodiment shown here, the two sheets are integral from the beginning. However, in an embodiment not shown, these two sheets could be initially separated, then superimposed and fixed to each other at the time of manufacture of the bag.

Au niveau de l'embouchure 10, les deux feuilles 12 et 13 sont munies de profilés de fermeture complémentaires 2 et 3.At the mouth 10, the two sheets 12 and 13 are provided with complementary closure profiles 2 and 3.

Ces profilés peuvent faire l'objet de nombreux modes de réalisation. L'invention n'est pas limitée au mode de réalisation précis illustré à la figure 1.These profiles can be the subject of many embodiments. The invention is not limited to the precise embodiment illustrated in FIG. figure 1 .

Dans le cas illustré ici, les profilés 2 et 3 sont respectivement du type mâle et femelle, comme cela est bien connu de l'homme de l'art. Toutefois, l'invention peut s'appliquer à d'autres types de profilés, notamment du type à crochets complémentaires.In the case illustrated here, the sections 2 and 3 are respectively of the male and female type, as is well known to those skilled in the art. However, the invention can be applied to other types of profiles, in particular of the complementary hook type.

Dans la forme de réalisation de la figure 1, les profilés 2 et 3 sont venus d'extrusion avec les feuilles 12 et 13 qui constituent le sachet.In the embodiment of the figure 1 , the profiles 2 and 3 came from extrusion with the sheets 12 and 13 which constitute the bag.

Toutefois, dans une variante de réalisation non représentée, ces profilés complémentaires pourraient être portés sur des voiles support rapportés sur les feuilles 12 et 13, par exemple par soudure à chaud ou collage.However, in an alternative embodiment not shown, these complementary profiles could be worn on support webs reported on the sheets 12 and 13, for example by hot welding or gluing.

Comme mentionné plus haut, le sachet comporte en outre un curseur 5 adapté pour actionner les profilés 2 et 3 à la fermeture et à l'ouverture.As mentioned above, the bag further comprises a slider 5 adapted to actuate the sections 2 and 3 at closing and opening.

Ce curseur peut faire l'objet de nombreux modes de réalisation classiques. Un exemple typique de curseur est décrit dans le document EP-A-0 479 661 . Dans la forme de réalisation présentée ici, le curseur, réalisé en matière plastique, comporte deux ailes latérales 51 et 52 (ou flancs), reliées entre-elles au niveau d'une embase 50 et qui définissent avec une semelle centrale allongée 55 deux couloirs de passage convergents pour les profilés de fermeture complémentaires emboîtables 2 et 3.This slider can be the subject of many conventional embodiments. A typical example of a cursor is described in the document EP-A-0 479 661 . In the embodiment presented here, the slider, made of plastic, has two lateral wings 51 and 52 (or flanks), interconnected at a base 50 and defining with an elongated central sole 55 two convergent passageways for the complementary interlocking closure profiles 2 and 3.

Ainsi, lorsque le sens de déplacement relatif du curseur 5 par rapport aux profilés de fermeture 2 et 3 tend à déplacer le curseur en forçant les profilés en prise, le sachet est fermé. Lorsque le curseur 5 est déplacé dans le sens inverse, le sachet est ouvert.Thus, when the relative direction of movement of the slider 5 with respect to the closure profiles 2 and 3 tends to move the slider by forcing the profiles into engagement, the bag is closed. When the cursor 5 is moved in the opposite direction, the bag is opened.

On notera que la base des flancs 51 et 52 du curseur se prolonge vers l'intérieur par des bossages 53 et 54 dirigés l'un vers l'autre.Note that the base of the flanks 51 and 52 of the slider is extended inwardly by bosses 53 and 54 directed toward each other.

En raison de la présence de ces bossages, les feuilles formant les parois principales du sachet convergent l'une vers l'autre, des profilés 2 et 3 vers (en direction de) ces bossages.Due to the presence of these bosses, the sheets forming the main walls of the bag converge towards each other, sections 2 and 3 towards (towards) these bosses.

En d'autres termes, à partir des profilés, les parois principales convergent l'une vers l'autre en direction de l'espace interne du sachet.In other words, from the profiles, the main walls converge towards each other in the direction of the internal space of the bag.

Le sachet comporte par ailleurs des moyens additionnels en relief 4 qui sont conçus pour assurer l'étanchéité en formant barrage entre les feuilles 12 et 13, en position de fermeture du sachet. Ils sont disposés sur l'intérieur des profilés de fermeture.The bag also comprises additional relief means 4 which are designed to ensure sealing by forming a barrier between the sheets 12 and 13, in the closed position of the bag. They are arranged on the inside of the closure profiles.

Autrement dit, ces moyens 4 sont placés sur la face interne de chaque feuille, en regard des flancs 51 et 52 du curseur 5 pour être sollicités vers leur position d'étanchéité par le curseur lorsque celui-ci est déplacé vers la position d'étanchéité.In other words, these means 4 are placed on the inner face of each sheet, facing the flanks 51 and 52 of the slider 5 to be urged towards their sealing position by the slider when it is moved towards the sealing position. .

Plus précisément, ces moyens 4 sont constitués chacun d'un bourrelet de matière plastique qui s'étend parallèlement à l'axe X-X' de déplacement du curseur.More specifically, these means 4 each consist of a plastic bead which extends parallel to the axis X-X 'of displacement of the cursor.

Pour assurer l'étanchéité, les bourrelets s'étendent exactement l'un en regard de l'autre.To seal, the beads extend exactly opposite one another.

Mais, comme exposé plus haut, il arrive que l'une des feuilles 12 et 13 du sachet subisse une légère translation perpendiculaire à la direction de déplacement du curseur, de sorte que les bourrelets 4 ne sont plus strictement en face l'un par rapport à l'autre.But, as explained above, it happens that one of the sheets 12 and 13 of the bag undergoes a slight translation perpendicular to the direction of movement of the cursor, so that the beads 4 are no longer strictly opposite one against to the other.

Il en résulte alors un défaut d'étanchéité.This results in a leakage fault.

C'est la raison pour laquelle les feuilles 12 et 13 comportent, sur leur face externe, au voisinage des bossages 53 et 54 du curseur, des moyens de butée 6 aptes à immobiliser les feuilles 12 et 13 relativement au curseur 5, selon une direction généralement perpendiculaire à l'axe X-X' de déplacement du curseur, par contact entre les bossages 53 et 54 et ces moyens de butée 6.This is the reason why the sheets 12 and 13 comprise, on their outer face, in the vicinity of the bosses 53 and 54 of the slider, stop means 6 able to immobilize the sheets 12 and 13 relative to the slider 5, in a direction generally perpendicular to the axis XX 'of displacement of the slider, by contact between the bosses 53 and 54 and these abutment means 6.

Dans la forme de réalisation exposée aux figures 1 à 3, ces moyens de butée sont constitués d'un bourrelet de matière qui s'étend tout le long de l'étendue transversale du sachet.In the embodiment set out in Figures 1 to 3 these abutment means consist of a bead of material which extends all along the transverse extent of the bag.

Dans la forme de réalisation de la figure 2, il s'agit de bourrelets rapportés sur les feuilles 12 et 13, tandis qu'à la figure 3, ces bourrelets viennent d'extrusion avec les feuilles 12 et 13.In the embodiment of the figure 2 , it is about beads reported on the sheets 12 and 13, while at the figure 3 these beads come from extrusion with the sheets 12 and 13.

Grâce à la présence de ces moyens de butée, on "cale" le positionnement des feuilles relativement au curseur de sorte que les moyens d'étanchéité additionnels 4 se trouvent parfaitement l'un en face de l'autre et assurent complètement leur fonction d'étanchéité.Thanks to the presence of these abutment means, "positioning" the positioning of the sheets relative to the slider so that the additional sealing means 4 are perfectly opposite one another and completely ensure their function of seal.

Par ailleurs, en raison de la présence des profilés 2 et 3 sur les feuilles 12 et 13, ces régions du sachet sont rigides ou peu déformables. Or, la présence de butées 6 contribuent à faire se rapprocher les feuilles 12 et 13.Moreover, because of the presence of the sections 2 and 3 on the sheets 12 and 13, these regions of the bag are rigid or slightly deformable. However, the presence of stops 6 contribute to bringing sheets 12 and 13 closer together.

Dans un mode de réalisation non représenté, on peut envisager de se dispenser de la présence des moyens d'étanchéité additionnels 4.In a not shown embodiment, it is conceivable to dispense with the presence of the additional sealing means 4.

Aux figures 4 à 6 sont représentées différentes formes de réalisation des moyens de butée 6. Pour faciliter la lecture de ces figures, les moyens de butée sont représentés légèrement séparés du curseur 5. Toutefois, dans la pratique, ils sont positionnés au plus près de ce curseur.To the Figures 4 to 6 Various embodiments of the abutment means 6 are shown. To facilitate the reading of these figures, the abutment means are shown slightly separated from the slider 5. However, in practice, they are positioned closer to this slider.

Dans le mode de réalisation de la figure 4, les moyens de butée sont constitués d'un bourrelet continu qui s'étend parallèlement à l'axe de déplacement X-X' du curseur.In the embodiment of the figure 4 , the abutment means consist of a continuous bead which extends parallel to the axis of displacement XX 'of the slider.

Dans la forme illustrée à la figure 5, ce bourrelet, parallèle à l'axe X-X', est discontinu et formé d'une série de tronçons, le plus grand intervalle ℓ 2 entre deux tronçons voisins étant inférieur à la dimension longitudinale ℓ 1 du curseur 5.In the form illustrated in figure 5 this bead, parallel to the axis X-X ', is discontinuous and formed of a series of sections, the largest interval ℓ 2 between two adjacent sections being smaller than the longitudinal dimension ℓ 1 of the slider 5.

Ainsi, quel que soit le positionnement du curseur, celui-ci se situe toujours en regard d'au moins un tronçon.Thus, whatever the positioning of the cursor, it is always facing at least one section.

Engin, dans le mode de réalisation de la figure 6, le bourrelet 6 est également discontinu et constitué d'une série de tronçons limités à leur plus simple expression, ce qui signifie qu'ils sont constitués de points.Engin, in the embodiment of the figure 6 , the bead 6 is also discontinuous and consists of a series of sections limited to their simplest expression, which means that they consist of points.

Là encore, le plus grand intervalle ℓ 3 entre deux tronçons voisins est inférieur à la dimension longitudinale ℓ 1 du curseur.Again, the largest interval ℓ 3 between two neighboring sections is smaller than the longitudinal dimension ℓ 1 of the slider.

Les feuilles, profilés de fermeture, moyens d'étanchéité additionnels et moyens de butée peuvent être réalisés en tout matériau plastique approprié et connu de l'homme de l'art.The sheets, closure profiles, additional sealing means and stop means may be made of any suitable plastic material and known to those skilled in the art.

De préférence, il s'agit d'une polyoléfine, très avantageusement de polyéthylène basse ou haute densité, voire de polypropylène.Preferably, it is a polyolefin, very advantageously low or high density polyethylene, or even polypropylene.

Dans les modes de réalisation illustrés aux figures annexées, les moyens de butée 6 sont disposés à l'extérieur du curseur 5.In the embodiments illustrated in the appended figures, the abutment means 6 are arranged outside the slider 5.

Toutefois, il est envisageable de prévoir sur les feuilles des moyens de butée additionnels, identiques ou similaires, du côté de l'espace interne du curseur. Ainsi, les bossages 53 et 54 se trouvent encadrés, sur leurs côtés opposés, par les moyens de butée.However, it is conceivable to provide on the sheets additional stop means, identical or similar, on the side of the internal space of the cursor. Thus, the bosses 53 and 54 are framed on their opposite sides by the stop means.
