Description

La présente invention concerne le domaine des sachets ou des feuilles équipés d'ensembles de fermeture ou d'accrochage.The present invention relates to the field of sachets or sheets equipped with closure or attachment assemblies.

On connaît de nombreux sachets, par exemple mais non exclusivement à usage ménager, équipés d'ensembles, au niveau de leurs embouchures, pour autoriser sur demande une succession d'ouvertures et de refermetures.Many bags are known, for example but not exclusively for household use, equipped with sets, at their mouths, to allow on request a succession of openings and reclosures.

On connaît en particulier de tels ensembles de fermeture composés de deux voiles support qui portent respectivement des éléments mâle/femelle complémentaires en regard au niveau de l'embouchure du sachet. On connaît également des ensembles de fermeture fonctionnellement équivalents comprenant des crochets sur des voiles destinés à être positionnés en regard au niveau de l'embouchure du sachet.In particular, such closure assemblies are known composed of two support webs which respectively carry complementary male / female elements opposite at the mouth of the bag. Also known functionally equivalent closure assemblies comprising hooks on sails intended to be positioned opposite the level of the mouth of the bag.

On connaît également dans différents domaines, en particulier dans le domaine de l'affichage, ou de l'emballage, des feuilles équipées d'ensembles d'accrochage destinés à coopérer avec des ensembles ou moyens d'accrochage complémentaires prévus sur une autre feuille ou sur un support associé.It is also known in various fields, in particular in the field of display or packaging, sheets equipped with attachment assemblies intended to cooperate with complementary assemblies or attachment means provided on another sheet or on an associated medium.

La demanderesse a constaté que dans certaines circonstances les ensembles de fermeture ou d'accrochage connus ne donnent pas totalement satisfaction.The Applicant has found that in certain circumstances known closure or hooking assemblies do not give complete satisfaction.

Cela s'applique en particulier aux ensembles de fermeture ou d'accrochage élaborés en polyoléfines, principalement polyéthylène et polypropylène. En effet, ces ensembles, après extrusion, et avant fixation sur des films destinés à composer les sachets ou des feuilles, sont généralement enroulés sur des bobines circulaires, à des fins de stockage. Or les polymères ainsi utilisés ont une mémoire élastique de leurs conditions de transformation et recristallisent dans le temps en passant par différentes phases et sous différents types de cristallites.This applies in particular to closure or fastening assemblies made of polyolefins, mainly polyethylene and polypropylene. Indeed, these sets, after extrusion, and before fixing on films intended to compose the bags or sheets, are generally wound on circular coils, for storage purposes. However, the polymers thus used have an elastic memory of their transformation conditions and recrystallize over time through different phases and under different types of crystallites.

Il s'ensuit de fortes tensions internes qui conduisent à des sortes de gauchissement ou cabrage pour les ensembles ainsi stockés sur bobines circulaires.It follows strong internal tensions that lead to sorts of warping or pitching for the sets thus stored on circular coils.

Ces courbures peuvent être très gênantes lors de la mise en oeuvre du processus de fixation des ensembles de fermeture ou d'accrochage sur le film destiné à composer le sachet ou sur les feuilles. En effet, l'on comprend aisément qu'en raison de ce gauchissement ou cabrage des ensembles, il est très difficile d'assurer une parfaite rectilinéarité de ces ensembles de fermeture ou d'accrochage après déroulement à partir du stockage en bobine. De ce fait, à l'utilisation, il est parfois difficile d'assurer la mise en prise des ensembles de fermeture ou d'accrochage complémentaires et par conséquent une fermeture correcte des sachets ou un accrochage satisfaisant des feuilles. Par ailleurs, il est souvent nécessaire de guider les ensembles pour les acheminer sur le film destiné à composer les sachets ou les feuilles, avant d'assurer leur fixation, notamment lorsque les ensembles de fermeture ou d'accrochage sont acheminés dans une direction transverse à la direction de déplacement du film. Et il s'avère que si le gauchissement des ensembles de fermeture ou d'accrochage est important ceux-ci peuvent échapper aux guides.These bends can be very troublesome during the implementation of the process of fixing closure or fastening assemblies on the film for composing the bag or on the sheets. Indeed, it is easy to understand that because of this warping or pitching of the assemblies, it is very difficult to ensure perfect rectilinearity of these closure or latching assemblies after unwinding from the reel storage. Therefore, in use, it is sometimes difficult to ensure the engagement of complementary closure or fastening assemblies and therefore a correct closure of the bags or a satisfactory attachment of the sheets. Furthermore, it is often necessary to guide the assemblies to route them on the film intended to compose the bags or sheets, before securing them, especially when the closing or fastening assemblies are routed in a direction transverse to the movement direction of the film. And it turns out that if the warping of closure or attachment assemblies is important these can escape the guides.

Diverses solutions consistant notamment à appliquer aux ensembles de fermeture une torsion inverse de celle appliquée au stockage pour supprimer l'effet mémoire ont déjà été proposées. On pourra se référer sur ce point au document US-A-6 616 881,Various solutions consisting in particular of applying to the closure assemblies a reverse twist of that applied to the storage to suppress the memory effect have already been proposed. Reference can be made here to US-A-6 616 881,

Cependant, cette solution ne donne pas totalement satisfaction.However, this solution does not give complete satisfaction.

La présente invention a pour but d'améliorer la situation.The present invention aims to improve the situation.

A cet effet, la présente invention propose un ensemble de fermeture ou d'accrochage destiné à équiper l'embouchure d'un sachet d'emballage ou une feuille, ledit ensemble de fermeture ou d'accrochage comprenant au moins un voile support qui porte un élément de fermeture ou d'accrochage, caractérisé par le fait qu'il comporte des découpes séquentielles couvrant une partie de la largeur du voile support, sur l'extérieur de l'élément de fermeture ou d'accrochage, réparties sur la longueur de l'ensemble, pour supprimer les effets de gauchissement, de courbure ou de cabrage de l'ensemble.For this purpose, the present invention proposes a closure or attachment assembly intended to equip the mouth of a packaging bag or a sheet, said closure or fastening assembly comprising at least one support veil which carries a closure or hooking element, characterized in that it comprises sequential cuts covering a part of the width of the support web, on the outside of the closure or fastening element, distributed over the length of the together, to eliminate the effects of warping, curvature or pitching of the assembly.

La demanderesse a en effet constaté que la réalisation de telles découpes sur les ensembles de fermeture ou d'accrochage, dans le voile support sur l'extérieur des éléments de fermeture ou d'accrochage, permettait de supprimer le gauchissement, courbure ou cabrage précité.The Applicant has indeed found that the realization of such cuts on the closure or fastening assemblies, in the support web on the outside of the closure elements or attachment, allowed to remove the warping, curvature or pitching aforementioned.

Il est vraisemblable que la zone de découpe ainsi réalisée dans les ensembles permet la relaxation des contraintes ou tout au moins permet d'éviter leur propagation et permet par conséquent de supprimer les gauchissements ou équivalents rencontrés sur les ensembles conformes à l'état de la technique.It is likely that the cutting zone thus produced in the sets allows relaxation of the stresses or at least prevents their propagation and therefore eliminates warping or equivalent encountered on the sets according to the state of the art .

Selon un mode de réalisation non limitatif conforme à la présente invention, les découpes séquentielles précitées débouchent sur une tranche des voiles support desdits ensembles, c'est-à-dire sur le bord de faible épaisseur de ceux-ci. En variante cependant les découpes séquentielles peuvent être réalisées sur une zone intermédiaire des voiles support desdits ensembles, c'est à dire entre les deux tranches latérales de ceux-ci, sans déboucher sur ces tranches.According to a non-limiting embodiment according to the present invention, the aforementioned sequential cutouts open on a slice of the support webs of said sets, that is to say on the thin edge thereof. As a variant, however, the sequential cuts may be made on an intermediate zone of the support webs of said assemblies, ie between the two lateral edges thereof, without opening onto these slices.

Selon une autre caractéristique avantageuse de la présente invention, les découpes séquentielles sont réalisées au pas des sachets. Cependant en variante, les découpes séquentielles peuvent être réalisées avec un pas très différent de celui des sachets si les moyens de fixation des ensembles sur les films formant lesdits sachets permettent de garantir un bon contact entre lesdits ensembles et lesdits films, y compris au voisinage de ces découpes.According to another advantageous characteristic of the present invention, the sequential cuts are carried out at the pitch of the bags. However, in a variant, the sequential cuts can be made with a pitch that is very different from that of the bags if the means for fixing the assemblies on the films forming the said sachets make it possible to guarantee good contact between the said sets and the said films, including in the vicinity of these cuts.

La présente invention concerne également les sachets et les feuilles obtenus à l'aide des ensembles de fermeture et d'accrochage précités,The present invention also relates to sachets and sheets obtained using the aforementioned closing and fastening assemblies,

Other features, objects and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings given as non-limiting examples and in which:
  • Figure 1 shows schematically a first embodiment of cutting according to the present invention.
  • FIG. 2 represents a second embodiment of cutting according to the present invention,

On aperçoit sur la Figure 1 annexée un ensemble 10 de fermeture ou d'accrochage conforme à la présente invention susceptible d'équiper l'embouchure d'un sachet d'emballage ou des feuilles et formé de deux profilés 12, 14, complémentaires munis par exemple d'éléments male/femelle complémentaires 122, 142 ou encore de crochets complémentaires 124, 144, portés par des voiles support 120, 140.FIG. 1 shows a closure or fastening assembly 10 according to the present invention capable of equipping the mouth with a packaging bag or sheets and formed of two complementary sections 12, 14 provided by example complementary male / female elements 122, 142 or complementary hooks 124, 144 carried by support webs 120, 140.

Comme on le voit sur la Figure 1 annexée selon l'invention les deux profilés 12, 14 sont munis chacun de découpes 13, 15, dans les voiles 120, 140, sur l'extérieur des éléments d'accrochage 124, 144. Ces découpes 13, 15 peuvent être formées au pas p des sachets. En d'autres termes, la distance p séparant deux découpes 13 ou 15 sur les profilés 12, 14 est dans ce cas égale à la largeur de l'embouchure des sachets sur lesquels les profilés sont destinés à être fixés. Cependant en variante, comme indiqué précédemment, les découpes séquentielles 13, 15 peuvent être réalisées avec un pas très différent de celui des sachets si les moyens de fixation des profilés sur les films formant lesdits sachets permettent de garantir un bon contact entre lesdits profilés 12, 14 et lesdits films, y compris au voisinage de ces découpes, c'est à dire si les moyens de fixation permettent d'éviter un décollement des profilés 12, 14, à ce niveau.As can be seen in FIG. 1 appended according to the invention, the two sections 12, 14 are each provided with cutouts 13, 15, in the webs 120, 140, on the outside of the attachment elements 124, 144. These cutouts 13, 15 may be formed at the pace p bags. In other words, the distance p separating two cuts 13 or 15 on the profiles 12, 14 is in this case equal to the width of the mouth of the bags on which the profiles are intended to be fixed. However, alternatively, as indicated above, the sequential cuts 13, 15 can be made with a pitch very different from that of the bags if the means for attaching the profiles to the films forming said bags make it possible to ensure good contact between said profiles 12, 14 and said films, including in the vicinity of these cuts, ie if the fastening means prevent a detachment of the profiles 12, 14, at this level.

Selon la représentation donnée sur la Figure 1, les découpes 13, 15 ont un contour rectangulaire. Cependant cette disposition n'est pas impérative.According to the representation given in FIG. 1, the cuts 13, 15 have a rectangular contour. However this provision is not imperative.

Par ailleurs selon la représentation donnée sur les figures 1 et 2, les découpes 13, 15 débouchent toutes sur la même tranche de profilés 12, 14. Elles s'étendent entre cette tranche et une zone adjacente aux éléments d'accrochage 124, 144, sans s'étendre sous ceux-ci.Moreover, according to the representation given in FIGS. 1 and 2, the cutouts 13, 15 all open onto the same slice of profiles 12, 14. They extend between this slice and an area adjacent to the fastening elements 124, 144, without extending beneath them.

On a néanmoins représenté une variante de réalisation sur la figure 8 selon laquelle les découpes 13, 15 sont réalisées sur une zone intermédiaire des voiles des profilés, c'est à dire entre les deux tranches latérales 30, 32 de ceux-ci, sans déboucher sur ces tranches et là encore sans s'étendre sous les éléments d'accrochage 122, 142.Nevertheless, an embodiment variant is shown in FIG. 8 according to which the cuts 13, 15 are made on an intermediate zone of the webs of the profiles, that is to say between the two lateral edges 30, 32 of these, without opening on these slices and again without extending under the fastening elements 122, 142.

A titre d'exemple non limitatif, dans le cadre de la variante illustrée sur la Figure 1, les découpes 13, 15 ont une largeur supérieure à leur hauteur h.By way of non-limiting example, in the context of the variant illustrated in FIG. 1, the cuts 13, 15 have a width greater than their height h.

On a représenté sur la Figure 2 annexée une variante d'un ensemble de fermeture conforme à la présente invention qui se distingue du premier mode de réalisation illustré sur la Figure 1 par le fait que les découpes 13, 15 formées dans les voiles 120, 140 ont une largeur très réduite et correspondent à des entailles de faible largeur qui s'étendent perpendiculairement à la tranche des profilés 12, 14. Le cas échéant les entailles 13, 15 illustrées sur la Figure 2 peuvent être formées d'une simple incision, sans enlèvement de matière.FIG. 2 shows a variant of a closure assembly according to the present invention which differs from the first embodiment illustrated in FIG. 1 by the fact that the cutouts 13, 15 formed in the sails 120, 140 have a very small width and correspond to nicks of small width which extend perpendicularly to the edge of the profiles 12, 14. Where appropriate the notches 13, 15 illustrated in Figure 2 may be formed of a simple incision, without removal of material.

On a représenté sur la Figure 3 annexée un exemple de réalisation de profilés de fermeture connu dans lequel les profilés 12, 14 comprennent respectivement un voile 120, 140 portant l'un un élément mâle 122, l'autre un élément femelle complémentaire 142. De tels profilés de fermeture étant bien connus de l'homme de l'art ne sont donnés ici qu'à titre d'illustration et ne seront pas décrits plus en détail par la suite.FIG. 3 shows an exemplary embodiment of known closure profiles in which the profiles 12, 14 respectively comprise a web 120, 140 carrying one male element 122, the other a complementary female element 142. From FIG. such closure profiles being well known to those skilled in the art are given here for illustrative purposes and will not be described in more detail later.

On a représenté sur la Figure 4 une autre variante d'ensemble de fermeture dans lequel les deux profilés 12, 14 comprennent respectivement un voile 120, 140 portant des éléments complémentaires de type crochets référencés 124, 144. Là encore un tel ensemble de fermeture étant bien connu de l'homme de l'art n'est donné qu'à titre d'illustration et ne sera pas décrit plus en détail par la suite.FIG. 4 shows another variant of a closure assembly in which the two sections 12, 14 each comprise a web 120, 140 carrying hook-type complementary elements referenced 124, 144. Here again such a closure assembly being well known to those skilled in the art is given for illustrative purposes and will not be described in more detail later.

On a représenté sur les Figures 5 et 6 deux variantes de réalisation respectivement similaires aux Figures 3 et 4 dans lesquelles l'un des voiles 120 s'étend seulement d'un côté des éléments de fermeture 122, 124. Une telle variante est également bien connu de l'homme de l'art et ne sera donc pas décrite dans le détail par la suite.FIGS. 5 and 6 show two variant embodiments respectively similar to FIGS. 3 and 4 in which one of the webs 120 extends only on one side of the closure elements 122, 124. Such a variant is equally well known to those skilled in the art and will not be described in detail later.

Enfin, on a représenté sur la Figure 7, en coupe transversale, la structure de base d'un curseur susceptible d'équiper les ensembles de fermeture précités. Ce curseur 20 comprend une semelle 22 munie de deux flancs latéraux 24, 26 et d'un muret central 28. Le muret 28 et les flancs latéraux 24, 26 définissent entre eux deux canaux 27, 29, non parallèles. Les canaux 27, 29 convergent en direction d'une extrémité axiale du curseur. Les canaux 27, 29 sont destinés à recevoir respectivement l'un des profilés 12, 14. L'homme de l'art comprendra ainsi aisément que lorsque le curseur 20 est déplacé vers une extrémité axiale de profilés de fermeture il tend à séparer ceux-ci et par conséquent à ouvrir le sachet. Au contraire, lorsque le curseur est déplacé vers la seconde extrémité des profilés de fermeture il tend à rapprocher ceux-ci et par conséquent à fermer le sachet,Finally, there is shown in Figure 7, in cross section, the basic structure of a slider capable of equipping the aforementioned closure assemblies. This slider 20 comprises a sole 22 provided with two lateral flanks 24, 26 and a central wall 28. The wall 28 and the lateral flanks 24, 26 define between them two channels 27, 29, nonparallel. The channels 27, 29 converge towards an axial end of the slider. The channels 27, 29 are intended to receive respectively one of the profiles 12, 14. Those skilled in the art will thus easily understand that when the slider 20 is moved towards an axial end of closure profiles it tends to separate those ci and therefore to open the bag. On the other hand, when the cursor is moved towards the second end of the closure profiles, it tends to bring them closer together and consequently to close the bag,

Les profilés de fermeture 12, 14 concernant la présente invention, équipés de découpes 13, 15 et le cas échéant d'un curseur 20 peuvent être associés à tout type de film susceptible de réaliser un sachet d'emballage ou des feuilles, notamment mais non exclusivement des films en matière plastique, voire composites. De même la fixation des profilés de fermeture ou d'accrochage 13, 15 sur ces films peut être réalisée par tout moyen approprié, de préférence par soudure thermique.The closure profiles 12, 14 concerning the present invention, equipped with cutouts 13, 15 and, where appropriate, with a slider 20 can be associated with any type of film capable of producing a packaging bag or sheets, in particular but not exclusively plastic films or even composites. Similarly, the attachment of the closure or fastening sections 13, 15 to these films can be achieved by any appropriate means, preferably by thermal welding.

Dans le cadre de la présente invention la hauteur h des découpes 13, 15 est de préférence comprise entre 1/3 et 1/10ème de la hauteur h0 des profilés de fermeture 13, 15.In the context of the present invention the height h of the cuts 13, 15 is preferably between 1/3 and 1/10 th of the height h0 of the closure profiles 13, 15.

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.

Selon les modes de réalisation illustrés sur les figures 1 à 8, les découpes 13, 15 sont orientées perpendiculairement aux bords 30, 32, des profilés de fermeture.According to the embodiments illustrated in Figures 1 to 8, the cuts 13, 15 are oriented perpendicularly to the edges 30, 32 of the closure profiles.

On a illustré sur la figure 9, une variante de réalisation selon laquelle les découpes 13, 15 sont obliques par rapport aux bords 30, 32.FIG. 9 illustrates a variant embodiment in which the cutouts 13, 15 are oblique with respect to the edges 30, 32.

Plus précisément, selon la figure 9, les découpes 13, 15 débouchent sur un bord 30 des profilés de fermeture. La disposition oblique des découpes illustrées sur la figure 9, est également applicable dans le cas où, comme indiqué précédemment, les découpes ne débouchent pas sur un bord des profilés de fermeture mais s'étendent entre ceux-ci (comme illustré schématiquement sur la figure 8).More precisely, according to FIG. 9, the cutouts 13, 15 open onto an edge 30 of the closure profiles. The oblique arrangement of the cutouts illustrated in FIG. 9 is also applicable in the case where, as indicated above, the cutouts do not open on one edge of the closure profiles but extend between them (as illustrated schematically in FIG. 8).

De préférence dans le cadre de la présente invention, les découpes obliques 13, 15 illustrées sur la figure 9 sont inclinées d'un angle α de l'ordre de 30 à 60° par rapport au bord 30 des profilés.Preferably in the context of the present invention, the oblique cuts 13, 15 illustrated in Figure 9 are inclined at an angle α of the order of 30 to 60 ° relative to the edge 30 of the profiles.

Plus précisément encore, les profilés de fermeture illustrés sur la figure 9 sont adaptés pour être déplacés dans le sens illustré par la flèche référencée D sur la figure 9 de telle sorte qu'un guide ou support fixe par rapport auquel les profilés de fermeture sont ainsi déplacés voit en premier l'extrémité 130 des découpes 13, 15 située vers l'intérieur des profilés de fermeture puis en dernier, le bord libre 132 des découpes qui débouche sur la tranche 30. Ainsi, les profilés de fermeture ne présentent pas de bord d'attaque aigu mais seulement des angles obtus en regard du guide ou support précité, ce qui évite tout risque d'accrochage entre les profilés de fermeture et les guides ou supports associés.More precisely still, the closure profiles illustrated in FIG. 9 are adapted to be displaced in the direction illustrated by the arrow referenced D in FIG. 9 so that a guide or support fixed relative to which the closure profiles are thus displaced first sees the end 130 of the cuts 13, 15 located towards the inside of the closure profiles and lastly, the free edge 132 of the cutouts which opens on the wafer 30. Thus, the closure profiles do not have an edge acute attack but only obtuse angles facing the aforementioned guide or support, which avoids any risk of attachment between the closure profiles and guides or associated supports.

La disposition oblique des découpes illustrée sur la figure 9 est ainsi particulièrement avantageuse lorsque les profilés de fermeture sont déplacés dans un guide pour leur fixation sur des films destinés à réaliser le sachet.The oblique arrangement of the cutouts illustrated in FIG. 9 is thus particularly advantageous when the closure profiles are moved in a guide for their attachment to the films for making the bag.

Selon la variante de réalisation illustrée sur la figure 9, les découpes 13, 15 ont des bords parallèles, le cas échéant sans enlèvement de matière comme évoqué précédemment.According to the variant embodiment illustrated in FIG. 9, the cutouts 13, 15 have parallel edges, where appropriate without removal of material as mentioned above.

On a illustré sur la figure 10, une variante de réalisation selon laquelle les découpes 13, 15 présentent des bords 134, 135, 154, 155 non parallèles entre eux. Les découpes 13, 15 forment dans ce cas des dièdres dont la concavité est dirigée et débouche vers le bord 30 d'un profilé de fermeture. On a représenté sur la figure 10, des découpes 13, 15 symétriques par rapport à un plan orthogonal au bord 30. Cependant cette disposition n'est pas impérative, les découpes 13, 15 peuvent en effet être dissymétriques par rapport à un tel plan orthogonal en bord 30.FIG. 10 shows a variant embodiment in which the cutouts 13, 15 have edges 134, 135, 154, 155 that are not parallel to one another. In this case, the cut-outs 13, 15 form dihedrams whose concavity is directed and open towards the edge 30 of a closure profile. FIG. 10 shows cutouts 13, 15 that are symmetrical with respect to a plane orthogonal to the edge 30. However, this provision is not imperative, the cutouts 13, 15 may indeed be dissymmetrical with respect to such an orthogonal plane. on board 30.

Ces découpes 13, 15 sont délimitées par des bords rectilignes 134, 135, 154, 155, inclinés chacun d'un angle compris entre 30 et 60° par rapport au bord 30 des profilés de fermeture. Cette disposition présente l'avantage que les profilés de fermeture peuvent être déplacés dans un sens quelconque par rapport au support ou guide fixe sans risque d'accrochage.These cuts 13, 15 are delimited by straight edges 134, 135, 154, 155, each inclined at an angle of between 30 and 60 ° relative to the edge 30 of the closure profiles. This arrangement has the advantage that the closure profiles can be moved in any direction relative to the support or fixed guide without risk of snagging.

On a illustré sur la figure 11, une autre variante de réalisation selon laquelle les découpes 13, 15, sont globalement parallèles aux bords 30, 32. Selon la figure 9, toutes les découpes 13, 15, d'un même profilé sont alignées.FIG. 11 shows another variant embodiment in which the cutouts 13, 15 are generally parallel to the edges 30, 32. According to FIG. 9, all the cutouts 13, 15 of the same profile are aligned.

On a représenté sur la figure 12, une autre variante de réalisation selon laquelle les découpes 13, 15, tout en étant globalement parallèles aux bords 30, 32 des profilés ne sont pas allignés.There is shown in Figure 12, another embodiment according to which the cutouts 13, 15, while being generally parallel to the edges 30, 32 of the profiles are not aligned.
