Abstract

The kit has a cursor (100) comprising a base (110), a central wall (140) carrying a sole (142), lateral side plates (120, 130), where the central wall and the side plates define two non-parallel channels. Complimentary male and female closure sections (200, 250) are provided in which the section (250) comprises a rib shaped structure (300) provided adjacent to the sole. The structure is supported on the sole when a tearing off stress is exerted on the cursor, so that the section (250) is supported against the associated side plate of the cursor.

Description

La présente invention concerne le domaine des sachets comprenant des dispositifs de fermeture actionnés par curseur.The present invention relates to the field of sachets comprising slider actuated closure devices.

De nombreux dispositifs de ce type ont déjà été proposés.Many devices of this type have already been proposed.

Les dispositifs de fermeture de sachet comprennent généralement deux éléments profilés de type mâle/femelle complémentaires ou de type crochets complémentaires conçus pour permettre de multiples ouvertures/fermetures successives.The bag closure devices generally comprise two complementary male / female type profile elements or complementary hook type designed to allow multiple successive openings / closures.

Le curseur a pour but de faciliter respectivement la mise en prise et la séparation des profilés.The purpose of the slider is to facilitate the engagement and separation of the sections, respectively.

On a représenté sur les figures 1 à 5 annexées un dispositif de fermeture à curseur conforme à l'état de la technique.FIGS. 1 to 5 show a slider closure according to the state of the art.

Comme on le voit sur ces figures, le curseur 100 comprend généralement une base 110 qui porte deux flasques latéraux 120, 130 et un muret central 140. Les flasques 120, 130 et le muret 140 définissent en combinaison deux canaux 150, 160 en partie au moins non parallèles. Ces canaux reçoivent des éléments respectifs liés aux deux profilés 200, 250.As seen in these figures, the slider 100 generally comprises a base 110 which carries two lateral flanges 120, 130 and a central wall 140. The flanges 120, 130 and the wall 140 define in combination two channels 150, 160 partly in less non-parallel. These channels receive respective elements related to the two sections 200, 250.

Les curseurs connus ont déjà rendu de grands services. Ils facilitent l'ouverture et la fermeture des sachets puisqu'il suffit de déplacer le curseur pour, selon le sens de déplacement de celui-ci, écarter ou mettre en prise les profilés en raison du non parallélisme des canaux 150, 160.Known sliders have already rendered great service. They facilitate the opening and closing of the bags since it is sufficient to move the cursor to, depending on the direction of movement thereof, spread or engage the profiles due to the non-parallelism of the channels 150, 160.

Cependant, les sachets ainsi équipés présentent un inconvénient grave : on constate parfois un arrachement des curseurs, et notamment un risque d'ingestion par des enfants.However, the bags thus equipped have a serious disadvantage: sometimes there is a tearing sliders, including a risk of ingestion by children.

Pour tenter de réduire ce risque, on a déjà proposé, comme illustré sur les figures annexées, de placer sur les bords libres des flasques 120, 130, des nervures longitudinales 122, 132, destinées à prendre position sous les profilés. Cependant, cette mesure ne s'avère pas suffisante. En cas d'effort important appliqué sur le curseur, les flasques 120, 130 sont écartés et le curseur arraché.To try to reduce this risk, it has already been proposed, as illustrated in the accompanying figures, to place on the free edges of the flanges 120, 130, longitudinal ribs 122, 132, intended to take position under the profiles. However, this measure is not sufficient. In case of significant effort applied to the slider, the flanges 120, 130 are spaced apart and the cursor torn off.

On a également proposé comme illustré sur les figures 3, 4 et 5 de placer une semelle 142 sur l'extrémité du muret central 140. La semelle 142 est destinée à prendre position sous les profilés 200, 250 comme on le voit sur les figures 4 et 5. Cependant, là encore, cette solution ne donne pas totalement satisfaction. En effet, la semelle 142 doit présenter une forme effilée dans le sens de la convergence des canaux 150, 160 pour ne pas perturber la fermeture du sachet. On constate ainsi en pratique que le risque d'arrachement du curseur demeure, notamment par pivotement et extraction par l'extrémité effilée de la semelle qui agit à la façon d'un coin sollicitant les profilés en écartement.It has also been proposed as illustrated in Figures 3, 4 and 5 to place a sole 142 on the end of the central wall 140. sole 142 is intended to take position under the profiles 200, 250 as seen in Figures 4 and 5. However, again, this solution does not give complete satisfaction. Indeed, the sole 142 must have a tapered shape in the direction of the convergence of the channels 150, 160 so as not to disturb the closure of the bag. It is thus found in practice that the risk of tearing of the slider remains, in particular by pivoting and extraction by the tapered end of the sole which acts in the manner of a wedge biasing the sections spaced.

Le document US-A-5664,299 a proposé une autre solution illustrée sur la figure 6 annexée qui consiste à ajouter, sur la face externe des voiles 202, 252 portant les profiles complémentaires de fermeture 200, 250, des nervures 204, 254 destinées à venir en appui sur les nervures longitudinales 122, 132 du curseur. Cette solution ne donne cependant pas totalement satisfaction. Il s'avère en effet que si une traction à l'arrachement est exercée sur le curseur, les nervures 204, 254 tendent à glisser sur les nervures 122, 132 et ceci tend à rapprocher les deux éléments de fermeture et à les guider vers le passage libre entre les nervures 122, 132 contrairement à l'objectif de blocage et retenue initial.The document US-5664.299 has proposed another solution illustrated in Figure 6 attached which is to add, on the outer face of the webs 202, 252 carrying the complementary closure profiles 200, 250, ribs 204, 254 intended to bear against the longitudinal ribs 122 , 132 of the slider. This solution does not give complete satisfaction. It turns out that if pulling traction is exerted on the slider, the ribs 204, 254 tend to slide on the ribs 122, 132 and this tends to bring the two closure elements together and to guide them towards the free passage between the ribs 122, 132 contrary to the purpose of blocking and initial retention.

Une autre solution a été proposée dans le document FR-A-2855 153 . Cette solution est illustrée sur la figure 7. Elle consiste à prévoir sur l'un au moins des éléments de fermeture, une structure 210, 260, concave vers l'intérieur du sachet, formant butée pour la semelle 242 afin d'interdire le retrait du curseur 100 sous l'effet d'une sollicitation à l'arrachement.Another solution has been proposed in the document FR-A-2855153 . This solution is illustrated in FIG. 7. It consists in providing at least one of the closure elements, a structure 210, 260, concave towards the inside of the bag, forming a stop for the soleplate 242 in order to prevent withdrawal. cursor 100 under the effect of a pulling request.

La présente invention a pour but de perfectionner les dispositifs connus en limitant le risque d'arrachement de curseur.The present invention aims to improve the known devices by limiting the risk of tearing slider.

Ce but est atteint dans le cadre de la présente invention grâce à un ensemble de fermeture comprenant deux éléments complémentaires susceptibles d'être successivement mis en prise et séparés, et un curseur comprenant une base, deux flasques latéraux, un muret central et une semelle liée au muret central, caractérisé par le fait que l'un au moins des deux éléments possède sur sa surface interne une structure susceptible de venir en appui sur la semelle sous l'effet d'une sollicitation à l'arrachement de sorte que sous l'effet de cet appui, ledit élément tende à être plaqué contre le flasque latéral associé du curseur.This object is achieved in the context of the present invention by means of a closure assembly comprising two complementary elements capable of being sequentially engaged and separated, and a slider comprising a base, two lateral flanges, a central wall and a linked sole. central wall, characterized by the fact that one least of the two elements has on its inner surface a structure capable of bearing on the sole under the effect of a pulling stress so that under the effect of this support, said element tends to be pressed against the side flange associated with the slider.

Comme cela sera explicité par la suite, la structure ainsi proposée dans le cadre de la présente invention, conduit, à l'opposé du document US-A-5,664,299 à renforcer le contact, et par conséquent la friction, entre les flasques latéraux du curseur et l'ensemble de fermeture en cas de sollicitation à l'arrachement.As will be explained later, the structure thus proposed in the context of the present invention leads, in contrast to the document US Patent 5,664,299 to reinforce the contact, and consequently the friction, between the lateral flanges of the slider and the closure assembly in the event of pulling stress.

La présente invention concerne également les sachets équipés d'un tel ensemble de fermeture.The present invention also relates to sachets equipped with such a closure assembly.

La présente invention peut trouver application dans tout type de sachets. Pour cette raison, on ne décrira pas dans le détail par la suite les moyens de réalisation du sachet lui-même, ni son ou ses matériaux constitutifs.The present invention can find application in any type of sachets. For this reason, it will not be described in detail later means of making the bag itself, or its or its constituent materials.

Il en sera de même pour les profilés de fermeture 200, 250. Ils ne sont pas limités à la géométrie représentée sur les figures annexées. Ces profilés peuvent être du type mâle/femelle complémentaire, du type crochet complémentaire, du type velours/crochet complémentaire, ou tout autre structure équivalente. Ils peuvent être réalisés en tout matériau approprié. Les profilés de fermeture 200, 250 peuvent être venus de matière avec les parois du sachet, par exemple venus d'extrusion ou rapportés et fixés sur les parois du sachet par tout moyen approprié.It will be the same for the closing profiles 200, 250. They are not limited to the geometry shown in the accompanying figures. These profiles may be of the complementary male / female type, complementary hook type, velvet / complementary hook type, or any other equivalent structure. They can be made of any suitable material. The closure profiles 200, 250 may be integral with the walls of the bag, for example extrusion or reported and fixed on the walls of the bag by any suitable means.

De même, la structure générale du curseur 100 et son matériau constitutif ne seront pas décrits dans le détail par la suite. On s'attachera à décrire la caractéristique essentielle de l'invention.Similarly, the general structure of the slider 100 and its constituent material will not be described in detail later. We will attempt to describe the essential characteristic of the invention.

Le curseur 100 peut être réalisé en métal ou en matière plastique. Il comprend une base 110, deux flasques latéraux 120, 130 et un muret central 140 qui porte une semelle 142. Les flasques latéraux 120, 130 et le muret central 140 définissent en combinaison deux canaux 150, 160 au moins en partie non parallèles.The slider 100 may be made of metal or plastic. It comprises a base 110, two side flanges 120, 130 and a central wall 140 which carries a flange 142. The side flanges 120, 130 and the central wall 140 define in combination two channels 150, 160 at least partly non-parallel.

Comme indiqué précédemment, selon l'invention, l'un au moins des deux éléments complémentaires 200, 250 de l'ensemble de fermeture possède une structure 300 adaptée pour venir en appui sur la semelle 142 lorsqu'une sollicitation à l'arrachement est exercée sur le curseur 100. Selon la représentation donnée sur les figures 8 et 9, seul l'élément 250 est équipé d'une telle structure 300.As indicated above, according to the invention, at least one of the two complementary elements 200, 250 of the closure assembly has a structure 300 adapted to bear on the sole 142 when pulling stress is exerted on the slider 100. According to the representation given in FIGS. 8 and 9, only the element 250 is equipped with such a structure 300.

De préférence, dans le cadre de l'invention, cette structure 300 est formée d'une nervure adjacente à la semelle 142, solidaire de la face interne 252 du voile 254 qui porte l'élément de fermeture 250.Preferably, in the context of the invention, this structure 300 is formed of a rib adjacent to the sole 142, integral with the inner face 252 of the web 254 which carries the closure element 250.

La structure 300 est conçue de sorte que lorsqu'elle vient en appui sur la semelle 142, elle tende à plaquer l'élément 250 contre le flasque latéral associé 130 du curseur comme on le voit à l'examen comparé des figures 8 et 9.The structure 300 is designed so that when it bears on the sole 142, it tends to press the element 250 against the associated lateral flange 130 of the slider as seen in the comparative examination of FIGS. 8 and 9.

Ainsi une friction importante est générée entre cet élément de fermeture 250 et le curseur 100.Thus a significant friction is generated between this closure member 250 and the slider 100.

L'homme de l'art comprendra qu'ainsi en cas de tentative d'arrachement du curseur, la friction obtenue interdit le retrait du curseur.Those skilled in the art will understand that in the event of an attempt to tear the slider, the friction obtained prohibits removal of the slider.

Plus précisément encore, pour obtenir l'effet précité, de préférence :

  • la nervure 300 est au moins légèrement effilée en direction de son extrémité libre,
  • la face 302 de la nervure 300 dirigée vers la semelle 142 est, au repos, parallèle à la face en regard 1420 de la semelle 142, voire diverge au moins légèrement par rapport à cette face 1420, en direction de son extrémité libre,
  • la hauteur h1 de la nervure 300 est telle que le cumul de cette hauteur h1 et de l'épaisseur e2 du voile 254 soit supérieur à l'intervalle i3 qui sépare le bord de la semelle 142 et le flasque latéral 130 ; ainsi la nervure 300 ne peut franchir ce passage sans venir en appui sur la semelle 142 et ainsi solliciter l'élément 250 en appui contre le flasque latéral 130.
More precisely, to obtain the above effect, preferably:
  • the rib 300 is at least slightly tapered towards its free end,
  • the face 302 of the rib 300 directed towards the sole 142 is, at rest, parallel to the facing face 1420 of the sole 142, or diverges at least slightly with respect to this face 1420, towards its free end,
  • the height h1 of the rib 300 is such that the accumulation of this height h1 and the thickness e2 of the web 254 is greater than the interval i3 which separates the edge of the sole 142 and the lateral flange 130; thus the rib 300 can not cross this passage without coming to bear on the sole 142 and thus urge the element 250 bearing against the lateral flange 130.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the particular embodiments which have just been described but extends to any variant within its spirit.
