Description

La présente invention concerne un procédé de fabrication d'un emballage en feuilles souples pour produits de tissus cellulosiques, l'emballage ainsi obtenu et la machine pour la mise en oeuvre du procédé.The present invention relates to a method for manufacturing a flexible sheet packaging for cellulosic tissue products, the packaging thus obtained and the machine for carrying out the method.

Il est connu des emballages en feuilles souples pour emballer des paquets de papier mouchoir, comportant un emballage en feuilles souples pourvu sur l'une de ses faces d'une prédécoupe en forme de trapèze dont la base inférieure la plus étroite supporte une languette adhésive montée à cheval sur cette base, de façon qu'une partie adhésive adhère sur la partie trapèzoïdale et une autre partie sur le reste de la face de l'emballage.Flexible sheet packaging is known for wrapping tissues packets, comprising a flexible sheet packaging provided on one of its faces with a trapezoidal pre-cut, the narrowest lower base of which supports a mounted adhesive tab. straddling this base, so that an adhesive part adheres to the trapezoidal part and another part to the rest of the face of the package.

Un tel emballage est enseigné par le EP-A-0 030 601. Ce type d'emballage, bien qu'il soit intéressant, car permettant à l'utilisateur une ouverture facile du paquet pour prélever un objet et ensuite sa fermeture temporaire jusqu'à réutilisation pour prélèvement d'un autre objet, présente l'inconvénient de nécessiter au cours de sa fabrication une étape de mise en place d'une languette adhésive. Ceci augmente le prix de l'emballage d'une part du coût de la languette adhésive, d'autre part du coût nécessaire à l'opération de mise en place de celle-ci à une position précise sur l'emballage au cours de la fabrication de ce dernier. Enfin, cette languette, au cours de l'utilisation de l'emballage peut finalement être arrachée, ce qui aura pour conséquence d'enlever à l'emballage la faculté d'être refermé pour conserver le restant des produits en vue d'une utilisation ultérieure.Such packaging is taught by EP-A-0 030 601. This type of packaging, although it is interesting, since it allows the user to easily open the package to pick up an object and then temporarily close it until reusable for removal of another object, has the disadvantage of requiring during its manufacture a step of placing an adhesive tab. This increases the price of the packaging on the one hand of the cost of the adhesive tab, on the other hand of the cost necessary for the operation of positioning it at a precise position on the packaging during the manufacture of the latter. Finally, this tab, during the use of the packaging can finally be torn off, which will have the consequence of removing from the packaging the ability to be closed to keep the rest of the products for use later.

Un premier but de l'invention est donc de proposer un procédé de fabrication d'un emballage en feuilles souples pour produits de tissus cellulosiques qui ne présente plus l'inconvénient de cette étape de positionnement de la languette adhésive.A first object of the invention is therefore to propose a method of manufacturing a packaging in flexible sheets for cellulosic tissue products which no longer has the disadvantage of this step of positioning the adhesive tab.

Ce but est atteint par le fait que le procédé de fabrication consiste:

  • à pré-découper une languette dans une feuille ou une bande de matériau souple à intervalles réguliers correspondant au périmètre de la forme à envelopper et à une position déterminée;
  • à séparer la feuille en deux selon une direction perpendiculaire à l'axe de symétrie de la languette et au niveau d'une ligne passant par la partie inférieure de la languette;
  • à déposer une bande de thermocolle à intervalles réguliers au verso de l'extrémité pré-découpée de la languette;
  • à faire chevaucher les bords de séparation de la feuille;
  • à souder ensemble les bords de séparation superposés aux endroits non pourvus de thermo-colle;
  • à interrompre la soudure à intervalles réguliers aux endroits de la pré-découpe constituant la languette;
  • à constituer l'emballage des produits par enroulement autour des produits et pliage des parties de feuilles dépassant.
This object is achieved by the fact that the manufacturing process consists of:
  • pre-cutting a tongue from a sheet or strip of flexible material at regular intervals corresponding to the perimeter of the shape to be wrapped and to a determined position;
  • dividing the sheet in two in a direction perpendicular to the axis of symmetry of the tongue and at a line passing through the lower part of the tongue;
  • applying a strip of thermocolle at regular intervals on the back of the pre-cut end of the tongue;
  • overlapping the separation edges of the sheet;
  • welding together the overlapping separation edges at places not provided with thermo-adhesive;
  • interrupting the welding at regular intervals at the places of the pre-cut constituting the tongue;
  • to constitute the packaging of the products by winding around the products and folding the protruding sheet parts.

Un autre but de l'invention est de proposer un procédé de fabrication qui en plus de sa simplification permette d'assurer une préhension facile de la languette en vue de l'ouverture aisée du paquet.Another object of the invention is to propose a manufacturing process which in addition to its simplification makes it possible to ensure easy gripping of the tongue for easy opening of the package.

Ce but est atteint par le fait qu'au cours du procédé de fabrication, dans l'étape de pré-découpe de la languette, les angles de la languette sont découpés et dans l'étape de dépot de la thermocolle, celle-ci est déposée à une distance déterminée du bord de la languette de façon que ce bord constitue une portion aisément soulevable.This object is achieved by the fact that during the manufacturing process, in the step of pre-cutting the tongue, the angles of the tongue are cut and in the step of depositing the thermo-adhesive, it is deposited at a determined distance from the edge of the tongue so that this edge constitutes an easily liftable portion.

Un autre but de l'invention est de proposer un emballage dans lequel le risque d'arrachement de la partie adhésive d'une languette d'ouverture et de fermeture de l'emballage est supprimé.Another object of the invention is to provide a packaging in which the risk of tearing off the adhesive part of an opening and closing tongue of the packaging is eliminated.

Ce but est atteint par le fait que l'emballage comporte une soudure continue ou discontinue entre deux parties de l'emballage faisant le tour du produit à emballer, cette soudure étant au moins interrompue une fois par une languette prédécoupée dans cet emballage et dont une zone au voisinage de la partie la plus étroite de cette languette est totalement découpée et comporte une zone adhésive qui vient se coller sur la partie inférieure de l'emballage.This object is achieved by the fact that the packaging comprises a continuous or discontinuous welding between two parts of the packaging going around the product to be packaged, this welding being interrupted at least once by a tab precut in this packaging and one of which zone in the vicinity of the narrowest part of this tab is completely cut out and has an adhesive zone which is adhered to the lower part of the packaging.

Selon une particularité de l'invention, la pré-découpe a une forme convexe.According to a feature of the invention, the pre-cut has a convex shape.

Selon une autre particularité de l'invention, la pré-découpe a une forme trapézoïdale.According to another feature of the invention, the precut has a trapezoidal shape.

Selon une autre particularité de l'invention, l'emballage comporte une face supérieure, une face inférieure, des côtés latéraux avant et arrière.According to another feature of the invention, the packaging has an upper face, a lower face, front and rear lateral sides.

Selon une autre particularité de l'invention, l'emballage est de révolution et comporte une face supérieure et inférieure.According to another feature of the invention, the packaging is of revolution and has an upper and lower face.

Selon une autre particularité de l'invention, la pré-découpe est située sur la face supérieure ou inférieure.According to another feature of the invention, the pre-cut is located on the upper or lower face.

Selon une autre particularité de l'invention, la pré-découpe est située sur les côtés.According to another feature of the invention, the pre-cut is located on the sides.

Un autre but de l'invention est de proposer une machine pour la mise en oeuvre du procédé.Another object of the invention is to propose a machine for implementing the method.

Ce but est atteint par le fait que la machine comporte:

  • un poinçon de découpe et de pré-découpe;
  • un couteau de partage;
  • un dispositif d'application à intervalles réguliers sur la portion de bande pré-découpée et dans la partie extrême de la pré-découpe d'une colle;
  • un dispositif de superposition des bords des deux bornes obtenues par partage de la bande initiale;
  • un dispositif de soudure associé à un dispositif de détection de la pré-découpe et d'interruption au niveau de celle-ci de la soudure.
This object is achieved by the fact that the machine comprises:
  • a cutting and pre-cutting punch;
  • a sharing knife;
  • an application device at regular intervals on the portion of pre-cut strip and in the extreme part of the pre-cut of an adhesive;
  • a device for superimposing the edges of the two terminals obtained by sharing the initial strip;
  • a welding device associated with a device for detecting the precut and interrupting it at the weld level.

La présente invention apparaîtra plus clairement à la lecture de la description ci-après faite en référence aux dessins annexés dans lesquels :

  • la figure 1 représente une vue de dessus de la bande de feuille souple constituant l'emballage au cours des étapes du procédé;
  • la figure 2 représente une vue en perpective d'un emballage de forme parallèlépipédique obtenu après mise en oeuvre du procédé de l'invention;
  • la figure 3 représente une vue en perspective d'un emballage obtenu selon le procédé de l'invention pour un objet ayant une forme de révolution.
The present invention will appear more clearly on reading the description below made with reference to the accompanying drawings in which:
  • FIG. 1 represents a top view of the strip of flexible sheet constituting the packaging during the stages of the process;
  • FIG. 2 represents a perspective view of a packaging of parallelepipedal shape obtained after implementation of the method of the invention;
  • FIG. 3 represents a perspective view of a package obtained according to the method of the invention for an object having a shape of revolution.

Le procédé et l'emballage selon l'invention vont maintenant être décrits à l'aide des figures 1 et 2.The method and the packaging according to the invention will now be described with the aid of FIGS. 1 and 2.

Une feuille souple de matériau d'emballage, tel que par exemple en polyéthylène, de préférence sous forme de bande (1), comporte une partie centrale (10) et des parties latérales (11, 12) délimitées par des lignes de pliage longitudinales (13, 14) qui constituent les arêtes supérieure et inférieure qui forment le pourtour de l'emballage parallèlépipédique représenté à la figure 2.A flexible sheet of packaging material, such as for example polyethylene, preferably in the form of a strip (1), comprises a central part (10) and lateral parts (11, 12) delimited by longitudinal fold lines ( 13, 14) which constitute the upper and lower edges which form the periphery of the parallelepipedic packaging shown in FIG. 2.

La partie centrale est subdivisée en deux parties, pas forcément de dimension égale, par une ligne pointillée (8) qui prolonge la ligne de découpe représentée par un outil de découpe (2). Cette ligne passe au ras de l'extrémité d'une pré-découpe formée dans une des deux parties (10A, 10B) délimitées par la ligne (8). Cette pré-découpe (100) comporte des bords (101, 102) partiellement pré-découpés et dans une variante avantageuse de l'invention, une portion (103), entièrement découpée, constituant l'extrémité la plus étroite de la languette.The central part is subdivided into two parts, not necessarily of equal size, by a dotted line (8) which extends the cutting line represented by a cutting tool (2). This line runs flush with the end of a pre-cut formed in one of the two parts (10A, 10B) delimited by the line (8). This pre-cut (100) has edges (101, 102) partially pre-cut and in an advantageous variant of the invention, a portion (103), entirely cut, constituting the narrowest end of the tongue.

Dans une variante de l'invention, les pré-découpes (101, 102) peuvent s'étendre légèrement au-delà de la zone (10) dans la bande de matériau qui constitue la partie adjacente, en l'occurrence, selon le mode d'exécution représenté à la figure (1), la bande (11). Dans une disposition inverse, ce serait la bande (12). La bande (1) de matériau est partagée en deux au niveau de l'outil de découpe (2) et forme deux bandes (10A, 10B) dont les bords nouvellement découpés sont référencés (15) pour la partie (10A), (16) pour la partie (10B).In a variant of the invention, the pre-cuts (101, 102) may extend slightly beyond the zone (10) in the strip of material which constitutes the adjacent part, in this case, depending on the mode. shown in Figure (1), the strip (11). In a reverse arrangement, it would be the strip (12). The strip (1) of material is split in two at the cutting tool (2) and forms two strips (10A, 10B) whose newly cut edges are referenced (15) for the part (10A), (16 ) for part (10B).

Après découpe de cette bande, et à intervalles réguliers correspondant aux emplacements de la languette (100), et en particulier à proximité de l'extrémité (103) de cette languette, la machine de fabrication de l'emballage met en place une portion de thermocolle (7). Après cette étape de mise en place de la portion de thermocolle (7), la machine de fabrication rapproche les bords (15, 16) correspondant aux parties (10A) et (10B) découpées de façon à ce que ces bords viennent se chevaucher comme représenté sur la portion de la figure délimitée par les lignes mixtes (4, 5).After cutting this strip, and at regular intervals corresponding to the locations of the tongue (100), and in particular near the end (103) of this tongue, the packaging manufacturing machine installs a portion of thermocolle (7). After this step of placing the portion of thermo-adhesive (7), the manufacturing machine brings the edges (15, 16) corresponding to the parts (10A) and (10B) cut so that these edges overlap as represented on the portion of the figure delimited by the mixed lines (4, 5).

Dans une étape ultérieure, les parties superposées des portions centrales (10A, 10B) sont soudées entre elles par une ligne de soudure (6) d'un dispositif de soudure de la machine de fabrication. Bien entendu, les pré-découpes constituant les languettes sont disposées à intervalles réguliers représentés par la distance (d) correspondant environ au périmètre des objets à emballer plus une partie permettant une légère superposition des bords de découpe transversaux de la bande avant soudure et pliage pour constituer l'emballage autour du produit. Les bords de découpe transversaux de la bande sont représentés par les lignes mixtes (3, 4, 5).In a subsequent step, the superimposed parts of the central portions (10A, 10B) are welded together by a welding line (6) of a welding device of the manufacturing machine. Of course, the pre-cuts constituting the tongues are arranged at regular intervals represented by the distance (d) corresponding approximately to the perimeter of the objects to be packaged plus a part allowing a slight superposition of the transverse cutting edges of the strip before welding and folding for constitute the packaging around the product. The transverse cutting edges of the strip are represented by the mixed lines (3, 4, 5).

Après découpe d'une portion de bande ainsi obtenue, par exemple entre les lignes pointillées (4, 5) correspondant au périmètre du produit à emballer, ou éventuellement à une dimension légèrement supérieure, la partie de la bande découpée est pliée de façon à constituer les arêtes (40,41,42) représentées par les lignes de trait fin sur la figure 1.After cutting a portion of strip thus obtained, for example between the dotted lines (4, 5) corresponding to the perimeter of the product to be packaged, or possibly at a slightly larger dimension, the part of the cut strip is folded so as to constitute the edges (40, 41, 42) represented by the fine lines in FIG. 1.

L'emballage ainsi obtenu, dans le cas d'un produit parallèlépipédique à emballer, comporte une face avant (1) sur laquelle se trouve la languette, à l'opposé une face arrière, deux côtés latéraux opposés, un côté supérieur et un côté inférieur.The packaging thus obtained, in the case of a parallelepiped product to be packaged, comprises a front face (1) on which the tongue is located, opposite a rear face, two opposite lateral sides, an upper side and a side inferior.

Il est bien évident que la languette (100) peut être disposée sur l'une des faces supérieure ou inférieure ou sur l'un des côtés latéraux, supérieur ou inférieur.It is obvious that the tongue (100) can be arranged on one of the upper or lower faces or on one of the lateral, upper or lower sides.

La figure 3 représente une variante d'emballage dans lequel la languette est prédécoupée selon une forme convexe, ce qui permet, par exemple, l'emballage de produits ayant une forme de révolution, comme représenté sur cette figure.FIG. 3 represents a variant of packaging in which the tongue is precut in a convex shape, which allows, for example, the packaging of products having a shape of revolution, as shown in this figure.

Bien évidemment, ce type d'emballage n'est nullement limité à l'emballage de papier mouchoir mais peut également s'appliquer à tout type de produit, tel que serviettes, garnitures périodiques, couches etc.Obviously, this type of packaging is by no means limited to tissue paper packaging, but can also be applied to any type of product, such as towels, periodical linings, diapers, etc.

La portion de thermocolle (7) appliquée sur la partie de la languette (100) qui vient se superposer sur une partie (10B) de la bande inférieure permet de maintenir l'emballage fermé avant usage. Une ouverture aisée par l'utilisateur est obtenue en tirant sur la partie totalement découpée (103). L'utilisateur extrait une partie des produits contenus dans l'emballage et la thermocolle ayant la propriété de conserver une qualité adhésive, même après séparation, permet ensuite à l'utilisateur de refermer l'emballage, de façon à conserver le reste des produits qui n'a pas été utilisé.The portion of thermo-adhesive (7) applied to the part of the tongue (100) which is superimposed on a part (10B) of the lower strip makes it possible to keep the packaging closed before use. Easy opening by the user is obtained by pulling on the completely cut out part (103). The user extracts part of the products contained in the packaging and the thermo-adhesive having the property of retaining an adhesive quality, even after separation, then allows the user to close the packaging, so as to preserve the rest of the products which has not been used.

On comprend aisément que dans le procédé de fabrication on a ainsi éliminé l'opération de mise en place d'une languette adhésive qui nécessite à la fois un positionnement précis pour la superposer avec l'extrémité de la languette pré-découpée, mais également un positionnement en direction pour éviter que cette languette ne se retrouve de travers sur l'emballage.It is easy to understand that in the manufacturing process, the operation of placing an adhesive tab has been eliminated, which requires both precise positioning to superimpose it with the end. of the pre-cut tongue, but also positioning in the direction to prevent this tongue from being skewed on the packaging.

Par ailleurs, la machine permettant la fabrication de l'emballage ne nécessitant pas de dispositif de transfert permettant d'amener cette pièce suplémentaire constituée par la languette adhésive est par conséquent plus simple dans sa constitution.Furthermore, the machine for manufacturing the packaging does not require a transfer device for bringing this additional piece formed by the adhesive tongue is therefore simpler in its constitution.
