Abstract

A bag which includes additional closing profiles which are respectively actuated by a slide during opening and closing. The bag includes a wall portion which forms a veil which can be broken and which is designed in such a way that it covers the slide before the bag is used.

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 actuated closure profiles respectively when opening and closing with a cursor.

De tels sachets sont décrits par exemple dans les documents EP-A-0051010, EP-A-0102301 et EP-A-0479661.Such sachets are described for example in documents EP-A-0051010, EP-A-0102301 and EP-A-0479661.

Ces sachets actionnés à l'ouverture et à la fermeture par un curseur ont déjà rendu de grands services.These sachets activated at opening and closing by a slider have already done great service.

Les documents WO-A-9 706 062 et US-A-5 672 009 décrivent diverses modalités de fabrication de sachets à profilés de fermeture complémentaires, sans curseur, selon le préambule de la revendication 1.WO-A-9 706 062 and US-A-5 672 009 describe various methods of making pouches with additional closing profiles, without cursor, according to the preamble of claim 1.

Les curseurs facilitent en effet l'ouverture et la fermeture des sachets. La présence d'un curseur est en particulier fort appréciée par les personnes âgées ou mal voyantes.The sliders make it easier to open and close the bags. The presence of a cursor is particularly appreciated by elderly or visually impaired people.

Cependant, malgré leurs atouts, les sachets à curseur ne connaissent pas aujourd'hui le développement attendu.However, despite their advantages, slider bags do not not know the expected development today.

La présente invention a pour but de perfectionner ce domaine.The object of the present invention is to improve this field.

Ce but est atteint dans, le cadre de la présente invention grâce à un sachet tel que défini en revendication 1 annexée.This object is achieved in the context of the present invention thanks to a sachet as defined in claim 1 attached.

Comme on le comprendra à la lecture de la description qui va suivre, la présente invention permet ainsi, grâce à des moyens simples, d'interdire l'accès au curseur tant que le voile de couverture est en place.As will be understood on reading the description which will follow, the present invention thus allows, by simple means, to prohibit access to the cursor as long as the cover veil is in place.

On évite ainsi toute manipulation, qu'elle soit fortuite, innocente, voire mal veillante, notamment sur un rayonnage de grands magasins.This avoids any manipulation, whether fortuitous, innocent, even poorly watchful, especially on department store shelves.

D'autres caractéristiques, buts et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre et en regard des dessins annexés, donnés à titre d'exemple non limitatif et sur lesquels :

  • la figure 1 représente une vue en coupe d'un sachet présentant quelques-unes des caractéristiques de la présente invention, au cours d'une étape de fixation partielle des profilés de fermeture sur les parois du sachet
  • la figure 2 représente une vue en coupe du même sachet, après ouverture de celui-ci et
  • la figure 3 représente une vue similaire à la figure 1 d'un sachet conforme à la présente invention.
Other characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows and with reference to the appended drawings, given by way of nonlimiting example and in which:
  • FIG. 1 represents a sectional view of a bag presenting some of the characteristics of the present invention, during a step of partial fixing of the closure profiles on the walls of the bag
  • FIG. 2 represents a sectional view of the same bag, after opening it and
  • Figure 3 shows a view similar to Figure 1 of a bag according to the present invention.

On distingue sur la figure 1 un sachet 10 composé de deux parois parallèles 12, 14 définissant une embouchure 16 de sachet.We distinguish in Figure 1 a bag 10 composed of two walls parallel 12, 14 defining a mouth 16 of a bag.

Dans sa structure générale, un tel sachet peut être formé selon de nombreuses dispositions connues de l'homme de l'art.In its general structure, such a sachet can be formed according to numerous arrangements known to those skilled in the art.

Ainsi, par exemple, les deux parois 12, 14 du sachet peuvent être formées à partir d'une feuille commune repliée sur elle-même sous forme de deux volets globalement parallèles correspondant auxdites parois 12, 14 et fixées entre eux, au niveau de leur périphérie, sur trois côtés, par exemple par collage ou soudure thermique.Thus, for example, the two walls 12, 14 of the bag can be formed from a common sheet folded back on itself in the form of two generally parallel flaps corresponding to said walls 12, 14 and fixed to each other, at their periphery, on three sides, for example by bonding or thermal welding.

Dans ce cas, l'embouchure 16, qui correspond de préférence à une zone de liaison par collage ou soudure thermique entre les deux parois 12, 14 peut être parallèle et opposée à la ligne de pliage de la feuille, ou perpendiculaire à cette ligne de pliage (auquel cas le fond 19 du sachet est également formé par collage ou soudure des deux volets 12, 14 comme illustré de manière non limitative sur la figure 1).In this case, the mouth 16, which preferably corresponds to a bonding zone by bonding or thermal welding between the two walls 12, 14 can be parallel and opposite to the fold line of the sheet, or perpendicular to this fold line (in which case the bottom 19 of the bag is also formed by bonding or welding the two flaps 12, 14 as illustrated in a nonlimiting manner in FIG. 1).

En variante, les deux parois 12, 14, peuvent être formées de deux feuilles initialement séparées, globalement parallèles entre elles et fixées sur leur périphérie, sur quatre côtés, par exemple par collage ou soudure thermique comme indiqué précédemment.Alternatively, the two walls 12, 14 can be formed of two sheets initially separated, generally parallel to each other and fixed on their periphery, on four sides, for example by gluing or welding thermal as previously indicated.

Les sachets conformes à la présente invention sont équipés de profilés de fermeture complémentaires 20, 30 actionnés par un curseur 40.The bags according to the present invention are equipped with complementary closure profiles 20, 30 actuated by a slider 40.

Ces moyens peuvent faire l'objet de nombreux modes de réalisation connus en eux-mêmes.These means can be the subject of numerous embodiments known in themselves.

Ainsi par exemple, les profilés de fermeture complémentaires 20, 30 peuvent être formés de structures complémentaires de type mâle/femelle respectivement, ou encore de structures en crochets complémentaires.For example, the complementary closure profiles 20, 30 can be formed of complementary male / female structures respectively, or of additional hook structures.

L'homme de l'art connaít de nombreuses géométries de profilés de fermeture complémentaires décrites dans la littérature et/ou commercialisées de nos jours. Pour ces raisons, la géométrie des profilés de fermeture 20, 30 ne sera pas décrite plus en détail par la suite.Those skilled in the art know many geometries of profiles additional closures described in the literature and / or marketed today. For these reasons, the geometry of the profiles closure 20, 30 will not be described in more detail below.

Il en est de même pour le curseur 40.The same is true for cursor 40.

Celui-ci peut faire l'objet de nombreux modes de réalisation.This can be the subject of numerous embodiments.

Le curseur 40 peut être en particulier conforme aux dispositions décrites dans le document EP-A-0479661.The cursor 40 may in particular comply with the provisions described in document EP-A-0479661.

Pour cette raison, le curseur 40 ne sera pas décrit dans le détail par la suite.For this reason, the cursor 40 will not be described in detail by the following.

On notera cependant que, de préférence, le curseur 40, réalisé en matière plastique, comporte deux ailes latérales reliées entre elles au niveau d'une embase et qui définissent avec une semelle centrale allongée, deux couloirs de passage convergents pour les profilés de fermeture complémentaire emboítables 20, 30. Ainsi, lorsque le sens de déplacement relatif du curseur 40 par rapport aux profilés de fermeture 20, 30 tend à déplacer le curseur 40 en forçant les profilés de fermeture 20, 30 en prise, le sachet est fermé. Lorsque le curseur 40 est déplacé dans le sens inverse, le sachet est ouvert.Note, however, that preferably the cursor 40, produced in plastic material, has two side wings connected to each other at level of a base and which define with an elongated central sole, two converging passage lanes for closing profiles complementary nestable 20, 30. So when the direction of movement relative of the cursor 40 with respect to the closure profiles 20, 30 tends to move the cursor 40 by forcing the closing profiles 20, 30 in engagement, the bag is closed. When the cursor 40 is moved in the opposite direction, the bag is open.

Le ou les films composant les parois 12, 14 du sachet peut faire l'objet de nombreux modes de réalisation. Il s'agit de préférence d'un film plastique, très préférentiellement de polyoléfine, très avantageusement de polyéthylène basse ou haute densité voire de polypropylène. Cependant, l'invention n'est pas limitée à ces matériaux particuliers.The film or films making up the walls 12, 14 of the sachet can make the object of many embodiments. It is preferably a film plastic, very preferably of polyolefin, very advantageously of low or high density polyethylene or even polypropylene. However, the invention is not limited to these particular materials.

L'invention s'applique également à des sachets réalisés à base de matériau composite, tel que feuille à base de papier plastifiée ou métallisée, etc ...The invention also applies to sachets made from composite material, such as sheet based on plasticized or metallized paper, etc ...

Les profilés complémentaires 20, 30 sont portés par des voiles support respectifs 22, 32 fixés sur les parois du sachet comme on va le décrire par la suite.The complementary profiles 20, 30 are carried by sails respective support 22, 32 fixed on the walls of the bag as we will describe later.

Selon le mode de réalisation illustré sur la figure 1 annexée, l'un premier 22 de ces voiles support est fixé sur la surface interne 13 d'une paroi 12 à distance de la soudure 17 définissant l'embouchure 16. Sur la figure 1, la zone de liaison entre le voile support 22 et la paroi 12 est illustrée sous la référence générale 24. Cette zone de liaison peut être définie par collage ou soudure thermique entre la surface interne 13 de la paroi 12 et le voile support 22. Le cas échéant, comme cela est connu de l'homme de l'art, cette zone de liaison 24 peut être définie par exemple par soudure thermique de nervures venues d'extrusion sur le voile support 22 et/ou sur la paroi 12.According to the embodiment illustrated in Figure 1 attached, one first 22 of these support webs is fixed on the internal surface 13 of a wall 12 at a distance from the weld 17 defining the mouth 16. On the Figure 1, the connection area between the support web 22 and the wall 12 is illustrated under the general reference 24. This connection zone can be defined by bonding or thermal welding between the internal surface 13 of the wall 12 and the support web 22. Where appropriate, as is known from those skilled in the art, this connecting zone 24 can be defined for example by thermal welding of ribs from extrusion on the support web 22 and / or on the wall 12.

Le second voile support 32, selon le mode de réalisation illustré sur la figure 1, est pris en sandwich entre les deux parois 12, 14 au niveau de l'embouchure 16, et fixé sur celles-ci au niveau de la soudure 17.The second support web 32, according to the embodiment illustrated on Figure 1, is sandwiched between the two walls 12, 14 at the mouth 16, and fixed thereon at the weld 17.

Plus précisément, il est ainsi défini une liaison 17a entre une première face du voile support 32 et la paroi 12 , et une seconde liaison 17b entre la seconde face du voile support 32 et la seconde paroi 14.More precisely, it is thus defined a link 17a between a first face of the support web 32 and the wall 12, and a second connection 17b between the second face of the support web 32 and the second wall 14.

On observera, et il s'agit là d'un avantage important de l'invention, que la liaison ainsi définie entre le voile support 32 et les parois 12, 14, peut être réalisée à l'aide de mâchoires de soudure thermique classiques généralement utilisées pour assurer la fermeture d'un sachet, au niveau de l'embouchure de celui-ci, par liaison directe entre les parois 12, 14 du sachet selon la technique classique. De telles mâchoires de soudure thermique sont référencées 100, 110 sur la figure 1.We will observe, and this is an important advantage of the invention, that the connection thus defined between the support web 32 and the walls 12, 14, can be made using conventional thermal welding jaws generally used to ensure the closure of a sachet, at the level of the mouth of the latter, by direct connection between the walls 12, 14 of the bag according to the classic technique. Such welding jaws thermal are referenced 100, 110 in Figure 1.

L'homme de l'art comprendra aisément que la portion de la paroi 12 située entre les liaisons 24 et 17a recouvre ainsi à l'origine le curseur 40 pour interdire un accès direct à celui-ci.Those skilled in the art will readily understand that the portion of the wall 12 located between links 24 and 17a thus originally covers cursor 40 to prevent direct access to it.

Cependant, une fois cette portion de la paroi 12 rompue, l'utilisateur peut accéder librement et de manière classique en elle-même au curseur 40 pour respectivement ouvrir ou fermer le sachet par séparation ou imbrication des profilés 20, 30.However, once this portion of the wall 12 has broken, the user can freely and conventionally access the cursor 40 itself for respectively opening or closing the sachet by separation or nesting of profiles 20, 30.

A cette fin, la portion précitée de la paroi 12 peut être munie d'une ligne de faiblesse 11 s'étendant parallèlement aux liaisons 24, 17a, pour faciliter l'ouverture de cette portion de paroi.To this end, the aforementioned portion of the wall 12 can be provided with a line of weakness 11 extending parallel to the connections 24, 17a, for facilitate the opening of this portion of wall.

Par ailleurs, comme on l'a schématisé sur la figure 1, de préférence, la longueur L1 de la portion précitée de paroi 12 située entre les zones de liaison précitées 24 et 17a, c'est-à-dire la distance L1 séparant ces zones de liaison 24 et 17a, à l'état tendu de la portion de paroi 12 située entre celles-ci, est inférieure à la somme des longueurs correspondantes L2 et L3 des voiles support 22, 32 situées entre les zones de liaison 24 et 17a. L'homme de l'art comprendra que le respect de cette condition géométrique permet de faciliter l'accès au curseur 40 et aux profilés 20, 30 au niveau de l'ouverture 11 pratiquée dans la portion de paroi 12 située entre les zones de liaison 24 et 17a, après rupture de cette portion de paroi.Furthermore, as shown diagrammatically in FIG. 1, preferably, the length L1 of the above-mentioned portion of wall 12 located between the zones of above link 24 and 17a, i.e. the distance L1 between these areas of connection 24 and 17a, in the stretched state of the wall portion 12 located between these, is less than the sum of the corresponding lengths L2 and L3 support webs 22, 32 located between the connection zones 24 and 17a. Those skilled in the art will understand that compliance with this geometric condition facilitates access to the cursor 40 and to the profiles 20, 30 at the opening 11 made in the wall portion 12 located between the zones link 24 and 17a, after rupture of this wall portion.

Cet accès est schématisé sur la figure 2.This access is shown diagrammatically in FIG. 2.

De préférence, les sachets illustrés sur la figure 1 sont réalisés sur des machines de type FFS (Form, Fill and Seal), c'est-à-dire des machines conçues pour réaliser automatiquement des opérations de formation, remplissage et fermeture de sachets. La structure générale de ces machines connue en soi ne sera pas décrite dans le détail par la suite.Preferably, the bags illustrated in FIG. 1 are produced on FFS (Form, Fill and Seal) type machines, i.e. machines designed to carry out training operations automatically, filling and closing of sachets. The general structure of these machines known per se will not be described in detail below.

On rappelle cependant que ces machines dites FFS comprennent généralement un col de formage qui reçoit en entrée le film à l'état plan en provenance d'un dérouleur et fournit en sortie le film conformé en tube, une goulotte de remplissage qui débouche dans ce col de formage et par conséquent dans ledit tube, des moyens pour acheminer des profilés de fermeture et pour fixer ceux-ci sur le film, des moyens de soudure longitudinale pour fermer le tube longitudinalement et des moyens aptes à générer séquentiellement une première soudure transversale avant qu'un produit ne soit introduit dans le tube par la goulotte de remplissage, puis une seconde soudure transversale quand le produit a été introduit dans le tube, pour fermer un emballage autour de ce dernier.Remember, however, that these so-called FFS machines include generally a forming neck which receives the film in the plane state as input from an unwinder and provides the film-shaped tube output, a filling chute which opens into this forming neck and by therefore in said tube, means for conveying profiles of closure and to fix these on the film, welding means longitudinal to close the tube longitudinally and means suitable for sequentially generate a first transverse weld before a product is introduced into the tube through the filler neck, then a second transverse weld when the product has been introduced into the tube, to close a package around it.

Dans ce contexte de machine FFS, selon la présente invention, les voiles support 22, 32 portant les profilés de fermeture 20, 30 et le curseur 40 sont de préférence acheminés sur le film transversalement à la direction de déplacement de celui-ci et ce en amont du col de formage. Plus précisément, selon cette réalisation, le voile support 22 est fixé sur le film 12 au niveau de la zone de liaison 24, à l'aide de moyens appropriés, notamment de mâchoires à soudure thermique, en amont du col de formage, tandis que le second voile support 32 est fixé sur les parois 12, 14, au niveau de la zone de liaison 17, à l'aide des mâchoires de soudure 100, 110 établissant la soudure transversale dite "seconde" précédemment. In this context of an FFS machine, according to the present invention, the support webs 22, 32 carrying the closing profiles 20, 30 and the slider 40 are preferably conveyed on the film transversely to the direction displacement thereof and upstream of the forming neck. More specifically, according to this embodiment, the support web 22 is fixed to the film 12 at the connection area 24, using appropriate means, in particular heat-welded jaws, upstream from the neck forming, while the second support web 32 is fixed on the walls 12, 14, at the connection zone 17, using the welding jaws 100, 110 establishing the transverse weld called "second" previously.

Cependant, l'invention n'est pas limitée à la disposition des voiles support 22, 32 transversalement à la direction d'avance du film. En effet, l'invention peut également trouver application avec un acheminement des voiles support 22, 32 et de leur profilé de fermeture 20, 30 et curseur 40 associé, longitudinalement, c'est-à-dire parallèlement à la direction d'avance du film précité. Dans ce cas, les voiles support 22, 32 sont fixés sur les parois 12, 14 non plus à l'aide de mâchoires de soudure transversales, mais à l'aide de mâchoires longitudinales, c'est-à-dire de mâchoires situées parallèlement à la direction du col de formage, par exemple les mâchoires classiques en soi utilisées pour fermer longitudinalement le tube obtenu à la sortie du col de formage.However, the invention is not limited to the arrangement of sails support 22, 32 transversely to the direction of advance of the film. Indeed, the invention can also find application with a routing of support webs 22, 32 and their closing profile 20, 30 and slider 40 associated, longitudinally, i.e. parallel to the direction of advance of the aforementioned film. In this case, the support webs 22, 32 are fixed on the walls 12, 14 no longer using transverse welding jaws, but using longitudinal jaws, i.e. jaws located parallel to the direction of the forming neck, for example the jaws conventional per se used to longitudinally close the tube obtained at the exit from the forming neck.

On observera que dans le cas d'un dépôt longitudinal des voiles support 22, 32 les deux zones de liaison 17, 24 peuvent être réalisées simultanément et non point successivement comme on l'a décrit précédemment pour un dépôt transversal respectivement en amont et en aval du col de formage.It will be observed that in the case of a longitudinal deposition of the sails support 22, 32 the two connection zones 17, 24 can be produced simultaneously and not point successively as described previously for transverse deposition respectively upstream and downstream of the forming neck.

On a illustré sur la figure 3, un sachet selon l'invention, selon laquelle l'un des voiles support (ici celui référencé 32 situé du côté de l'embouchure 16) est formé de deux tronçons 32a, 32b, l'un 32a situé côté embouchure 16 et fixé sur les parois 12, 14 au niveau des zones 17a, 17b comme décrit précédemment, et l'autre 32b situé côté profilé 30, les deux tronçons 32a, 32b formant un dièdre à concavité dirigé vers l'extérieur, soit vers la paroi 12. Dans ce cas, les deux tronçons 32a, 32b, peuvent être formés d'éléments initialement séparés reliés entre eux par collage ou par soudure thermique au niveau du sommet 33 du dièdre précité ou encore être formé d'un élément unique replié sur lui-même à angle vif au niveau de ce sommet 33.Illustrated in Figure 3, a bag according to the invention, according to which one of the support sails (here the one referenced 32 located on the side of the mouth 16) is formed by two sections 32a, 32b, one 32a located on the side mouth 16 and fixed to the walls 12, 14 at the areas 17a, 17b as described above, and the other 32b located on profile side 30, both sections 32a, 32b forming a dihedral with a concavity directed towards the outside, or towards the wall 12. In this case, the two sections 32a, 32b, can be formed of initially separate elements linked together by gluing or by thermal welding at the top 33 of the above-mentioned dihedral or else be formed of a single element folded back on itself at a sharp angle at this summit 33.

L'homme de l'art appréciera par ailleurs que l'utilisation d'une portion de paroi recouvrant le curseur à l'origine permet de résoudre de façon simple les problèmes d'étanchéité généralement rencontrés sur les sachets équipés de profilés de fermeture actionnés par curseur. Bien entendu, pour assurer cependant une étanchéité suffisante des sachets après rupture de la paroi 12, y compris après manipulation du curseur 40 et donc ouverture du sachet, les voiles support 22, 32 et/ou profilés de fermeture 20, 30 et/ou curseur peuvent être pourvus de nombreuses dispositions visant à assurer l'étanchéité, notamment celles définies par la Demanderesse dans ses demandes de brevet FR 98 16236, FR 98 13732, FR 98 13734, FR 98 05681.Those skilled in the art will further appreciate that the use of a portion of wall covering the cursor at the origin allows to solve in a simple way the sealing problems generally encountered on bags fitted with slider-actuated closure profiles. Well understood, however to ensure sufficient sealing of the sachets after rupture of the wall 12, including after manipulation of the cursor 40 and therefore opening of the bag, the support webs 22, 32 and / or profiles of closure 20, 30 and / or slider can be provided with numerous provisions to ensure watertightness, in particular those defined by the Applicant in its patent applications FR 98 16236, FR 98 13732, FR 98 13734, FR 98 05681.

Bien entendu pour assurer l'étanchéité du sachet, il est nécessaire que les zones d'extrémité des voiles support 22, 32 s'étendant transversalement aux zones de liaison 24, 17, soient également prises en sandwich entre les bords latéraux des parois 12, 34 et fixées sur celles-ci.Of course to seal the bag, it is necessary that the end zones of the support webs 22, 32 extending transversely to the connection zones 24, 17, are also taken in sandwiched between the lateral edges of the walls 12, 34 and fixed thereon.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toutes variantes conformes aux revendications annexées.Of course, the present invention is not limited to the modes of particular achievements which have just been described, but extends to all variants according to the appended claims.
