Description

L'invention concerne un dispositif d'ouverture facile d'un emballage sous forme de portion triangulaire, ainsi qu'un emballage correspondant et son procédé de fabrication. Elle est particulièrement adaptée au domaine de l'emballage de conditionnement d'un produit alimentaire pâteux, comme du fromage. Nous appellerons par la suite emballage ou portion triangulaire tout emballage comprenant cinq faces, une base et un couvercle de forme s'approchant d'un triangle séparés par trois parois latérales.The invention relates to a device for easy opening of a packaging in the form of a triangular portion, and a corresponding packaging and its manufacturing process. It is particularly suited to the field of packaging packaging of a pasty food product, such as cheese. We will call later packaging or triangular portion any package comprising five faces, a base and a shaped lid approaching a triangle separated by three side walls.

Une première solution de l'art antérieur est décrite dans le brevet FR2597441 . Elle concerne un emballage dont la base est une portion d'un disque, de forme se rapprochant d'un triangle isocèle, comprenant deux grands côtés de même longueur correspondant au rayon du disque et un petit côté arrondi correspondant à une partie de la périphérie circulaire du disque. La solution d'ouverture décrite pour ce type d'emballage repose sur une bande de déchirure comprenant une extrémité à saisir, disposée sur l'arête de l'emballage correspondant au centre du disque, se séparant en deux bandes longeant les deux grands côtés de la base triangulaire puis remontant et se terminant vers le haut de la paroi latérale arrondie opposée à l'arête centrale de l'emballage. Cette solution permet l'ouverture de la portion par le déchirement de sa base triangulaire puis de la paroi latérale arrondie de la portion. Un premier inconvénient de cette solution est qu'elle convient mal aux emballages en matériau plastique comme du polypropylène par exemple. Un second inconvénient de cette solution est qu'elle entraîne l'ouverture d'une surface globale insuffisante pour pouvoir se saisir facilement du fromage sans s'en mettre sur les doigts.A first solution of the prior art is described in the patent FR2597441 . It relates to a package whose base is a portion of a disc, of shape approximating an isosceles triangle, comprising two large sides of the same length corresponding to the radius of the disc and a small rounded side corresponding to a portion of the circular periphery of the disc. The opening solution described for this type of packaging is based on a tear strip comprising an end to be grasped, disposed on the edge of the package corresponding to the center of the disc, separating into two strips along the two long sides of the triangular base then up and ending up the rounded side wall opposite the central ridge of the package. This solution allows the opening of the portion by the tearing of its triangular base and the rounded side wall of the portion. A first disadvantage of this solution is that it is poorly suited to plastic packaging such as polypropylene for example. A second disadvantage of this solution is that it causes the opening of a global surface insufficient to be able to grab the cheese easily without putting on the fingers.

Une seconde solution de l'art antérieur pour ouvrir ce type d'emballage est décrite dans le document EP0803439 . Elle repose sur deux bandes de déchirement parcourant les trois parois latérales de la portion triangulaire. Elles provoquent l'ouverture des parois latérales de la portion, la base et le couvercle restant disposés sur le fromage. Un premier inconvénient de cette solution vient du fait qu'elle est liée à un procédé de fabrication particulier de l'emballage qui repose sur la réalisation des parois latérales séparément par leur enroulement autour d'un mandrin, puis sur l'ajout de la base et du couvercle. D'autre part, un second inconvénient provient du fait que la saisie de la base et du couvercle de l'emballage après son ouverture avant la consommation de son contenu n'est pas aisée, se fait difficilement sans se salir les mains.A second solution of the prior art for opening this type of packaging is described in document EP0803439 . It rests on two bands of tearing traversing the three lateral walls of the triangular portion. They cause the opening of the side walls of the portion, the base and the remaining lid arranged on the cheese. A first drawback of this solution comes from the fact that it is related to a particular manufacturing process of the packaging which is based on the realization of the side walls separately by winding them around a mandrel, then on the addition of the base and the lid. On the other hand, a second disadvantage comes from the fact that the seizure of the base and the lid of the package after opening before consumption of its contents is not easy, is difficult without getting dirty hands.

Enfin dans le FR 2597436 on propose un dispositif pour l'ouverture facile d'un emballage triangulaire, comprenant une base, un couvercle et trois parois latérales une de petite dimension et deux de plus grande dimension. Deux bandes de déchirement se rejoignant pour former une languette et parcourent la paroi latérale de petite dimension et la base de l'emballage afin de provoquer le déchirement de la base et d'une surface importante de la petite paroi latérale lors de la traction de la languette.Finally in the FR 2597436 there is provided a device for easy opening of a triangular package, comprising a base, a lid and three side walls one of small size and two of larger size. Two tear strips join to form a tongue and run through the small sidewall and the base of the package to cause tearing of the base and a large surface of the small sidewall during pulling of the tongue. tongue.

Un premier objet de la présente invention consiste à proposer un dispositif d'ouverture pour un emballage de type triangulaire et l'emballage associé, qui permet l'ouverture d'une surface importante de l'emballage et bien disposée pour faciliter la saisie du fromage de manière conviviale.A first object of the present invention is to provide an opening device for a triangular type package and the associated package, which allows the opening of a large surface of the package and well arranged to facilitate the seizure of cheese in a friendly way.

L'invention concerne donc les emballages triangulaires, comme illustrés aux figures 2 et 6, comprenant une base 2, un couvercle 6 et trois parois latérales 13, 14 et 15.The invention thus relates to triangular packages, as illustrated in FIGS. figures 2 and 6 , comprising a base 2, a cover 6 and three side walls 13, 14 and 15.

Selon le premier mode d'exécution de l'invention, un tel emballage est fabriqué à partir d'un film 1 en matériau plastique, par exemple du polypropylène, comprenant une base 2 sensiblement triangulaire isocèle, dont les deux grands côtés de même longueur 3 et 4 délimitent respectivement deux parties 13 et 14 destinées à former des parois latérales de l'emballage après pliage. La base 2 comprend en outre un troisième coté 5 de plus petite dimension, arrondi car la base 2 est en fait une portion triangulaire issue d'un disque de centre O, qui délimite la base 2 d'une partie 15 dont le pliage formera la paroi latérale arrondie opposée au centre O de la portion. Le film 1 comprend de plus des parties d'angle 17, 18 placées dans cet ordre entre les parties 13 ou 14 et la partie 15, séparées par une ligne de pliage 19 qui formera une arête 19 de la future portion après pliage. Enfin, le film 1 comprend une partie 20 en forme de queue de poisson, symétrique autour de la ligne de pliage centrale 16 destinée à former la troisième arête de la portion après pliage, arête s'élevant verticalement au-dessus du centre O de la portion triangulaire. Cette partie 20 a pour fonction de former cette arête 16 ainsi que d'assurer l'étanchéité de la portion dans cette zone.According to the first embodiment of the invention, such a package is made from a film 1 of plastic material, for example polypropylene, comprising a substantially triangular base 2 isosceles, the two long sides of the same length 3 and 4 delimit respectively two portions 13 and 14 for forming side walls of the package after folding. The base 2 further comprises a third side 5 of smaller size, rounded because the base 2 is in fact a triangular portion from a disk of center O, which delimits the base 2 of a portion 15 whose fold will form the rounded side wall opposite the center O of the portion. The film 1 further comprises corner portions 17, 18 placed in this order between the parts 13 or 14 and the part 15, separated by a fold line 19 which will form an edge 19 of the future portion after folding. Finally, the film 1 comprises a part 20 in the shape of a fish tail, symmetrical around the central fold line 16 intended to form the third edge of the portion after folding, ridge rising vertically above the center O of the triangular portion. This part 20 has the function of forming this edge 16 as well as sealing the portion in this area.

Selon l'invention, deux bandes de déchirement 23, 25 sont respectivement disposées et thermosoudées le long des côtés 3 et 5 sur la base 2 du film 1. Ces deux bandes se rejoignent, sont superposées et liées l'une à l'autre le long d'une ligne de pliage 19 d'une zone angulaire, sur une partie d'angle 17 du film pour former une languette unique 27 qui s'étend au-delà du film 1. De plus, cette languette 27 traverse une petite surface de la partie latérale 13 au niveau de son intersection avec les parties 2, 17 et 15. Les deux bandes 23, 25 se prolongent au niveau de leur seconde extrémité sur les bords d'une partie de la paroi latérale 14 opposée à la zone angulaire portant la languette 27, respectivement en une bande 21 longeant la frontière entre les parties 14 et 20 et en une bande 22 longeant la frontière entre les parties 14 et 17 du film 1. Dans ce mode d'exécution, le film 1 est en polypropylène et deux prédécoupes 29 sont prévues sur la périphérie du film 1 autour de la languette 27.According to the invention, two tear strips 23, 25 are respectively arranged and heat-sealed along the sides 3 and 5 on the base 2 of the film 1. These two strips meet, are superimposed and are bonded to each other. along a fold line 19 of an angular region, on a corner portion 17 of the film to form a single tongue 27 which extends beyond the film 1. In addition, this tongue 27 passes through a small surface of the lateral portion 13 at its intersection with the parts 2, 17 and 15. The two strips 23, 25 extend at their second end on the edges of a portion of the side wall 14 opposite to the angular zone carrying the tongue 27, respectively in a strip 21 along the border between the parts 14 and 20 and in a strip 22 along the border between the parts 14 and 17 of the film 1. In this embodiment, the film 1 is made of polypropylene and two pre-cuts 29 are provided on the periphery of the film 1 around the tongue 27.

En variante, la même configuration comprenant deux bandes de déchirement peut être obtenue à partir d'une bande unique continue pliée de façon à former la languette 27 et les deux bandes de part et d'autre. Le terme "deux bandes" inclut donc aussi une réalisation de deux parties d'une même bande de déchirement. Une telle bande de déchirement peut être en polyester ou en polypropylène.Alternatively, the same configuration comprising two tear strips can be obtained from a single continuous strip folded to form the tongue 27 and the two strips on either side. The term "two bands" therefore also includes an embodiment of two parts of the same tear strip. Such a tear tape may be polyester or polypropylene.

Le film 1 est plié à chaud selon un procédé de fabrication connu, tel que celui décrit dans le document W02004/052753 , pour former la portion illustrée en perspective en figure 2, la base 2 se trouvant sur le dessus. Les lignes de pliage 16 et 19 forment les trois arêtes de la portion triangulaire, une partie des parties latérales 13, 14 et 15 du film, après un premier pliage autour respectivement des lignes 3, 4 et 5 forment les parois latérales de la portion terminée. L'extrémité de ces parties 13, 14 et 15 est à nouveau pliée par-dessus un couvercle 6 ajoutée en vis à vis de la base 2, après remplissage de l'emballage, pour permettre la fermeture étanche de l'emballage, selon des lignes non représentées. Les parties d'angles 17, 18 et 20 sont repliées sur les parties latérales de l'emballage. Le résultat obtenu est donc une portion sensiblement triangulaire isocèle, comprenant deux grandes parois latérales 13 et 14 de mêmes dimensions, se rejoignant sur une arête 16, et délimitées avec une petite paroi latérale arrondie 15 par deux arêtes 19.The film 1 is hot folded according to a known manufacturing process, such as that described in the document W02004 / 052753 , to form the portion illustrated in perspective in figure 2 , the base 2 being on the top. The fold lines 16 and 19 form the three edges of the triangular portion, a portion of the lateral portions 13, 14 and 15 of the film, after a first folding respectively around the lines 3, 4 and 5 form the side walls of the finished portion. . The end of these parts 13, 14 and 15 is folded over a lid 6 added facing the base 2, after filling the package, to allow sealing of the package, according to lines not shown. The corner portions 17, 18 and 20 are folded over the side portions of the package. The result obtained is therefore a substantially triangular portion isosceles, comprising two large side walls 13 and 14 of the same dimensions, joining on a ridge 16, and delimited with a small side wall rounded by two edges 19.

Avantageusement, la partie 17 comprenant la languette 27 est repliée sur la paroi latérale arrondie 15, plutôt que sur la paroi latérale 13, puis sur le couvercle 6. Selon une variante non illustrée, la languette 27 pourrait longer l'arête 19 sur la partie angulaire 18, au lieu de la partie 17, et rejoindre la base 2 en traversant la portion 15, au lieu de la paroi 13, ces parties angulaires 17 et 18 étant alors avantageusement repliées sur la paroi latérale 13 de la portion terminée et non sur la paroi 15. Ces configurations, par laquelle la languette 27 effectue une sorte de contour de l'arête 19, est partiellement enroulée autour de l'arête 19, permettent lors de sa traction, dont la partie en saillie est saisie manuellement au niveau du couvercle 6 de l'emballage, de faciliter l'initiation du découpage du film puisque le parcours de la languette 27 induit une résistance au simple dépliage de la portion et une direction particulière de la force de traction exercée qui est favorable au déchirement de la portion. Ce principe d'enroulement de la languette au niveau d'une arête de la portion peut se résumer par un pliage de la partie angulaire sur la paroi latérale opposée à la partie d'angle sur laquelle elle est disposée. En remarque, ce principe, appliqué à une solution de l'art antérieur telle que celle décrite dans le brevet FR2597441 au niveau de l'arête 16, permettrait aussi son amélioration.Advantageously, the portion 17 comprising the tongue 27 is folded over the rounded side wall 15, rather than on the side wall 13, then on the cover 6. According to a variant not shown, the tongue 27 could follow the edge 19 on the angular portion 18, instead of the portion 17, and join the base 2 through the portion 15, instead of the wall 13, these angular portions 17 and 18 then being advantageously folded over the side wall 13 of the completed portion and not on the wall 15. These configurations, by which the tongue 27 makes a kind of contour of the edge 19, is partially wrapped around the edge 19, allow during its traction, the protruding portion is manually entered at the lid 6 of the package, to facilitate the initiation of cutting the film since the path of the tongue 27 induces a resistance to simple unfolding of the portion and a particular direction of the pulling force exerted which is favorable to the tearing of the portion. This principle of winding the tongue at an edge of the portion can be summed up by folding the angular portion on the side wall opposite to the corner portion on which it is disposed. As a remark, this principle, applied to a solution of the prior art such as that described in the patent FR2597441 at the level of the ridge 16, also allow its improvement.

La figure 3 illustre la phase initiale de l'ouverture de la portion triangulaire dans laquelle la languette 27 a été tirée et a entraîné un déchirement de la portion dans la zone angulaire autour de l'arête 19. La figure 4 illustre la portion après son ouverture complète suite à la traction prolongée de la languette 27. Les deux bandes de déchirement 23 et 25 provoquent le déchirement de l'emballage le long des côtés 3 et 5 et donc l'ouverture de la surface totale de la base 2 puis les deux bandes de déchirement 21 et 22, qui s'étendent sensiblement sur toute l'épaisseur de l'emballage sur la paroi latérale 14, provoquent le déchirement de cette paroi latérale 14 sur toute sa surface.The figure 3 illustrates the initial phase of the opening of the triangular portion in which the tongue 27 has been pulled and has caused a tearing of the portion in the angular zone around the edge 19. figure 4 illustrates the portion after its complete opening following the prolonged pulling of the tongue 27. The two tear strips 23 and 25 cause the packaging to tear along the sides 3 and 5 and thus the opening of the total surface of the base 2 and then the two tear strips 21 and 22, which extend substantially over the entire thickness of the package on the side wall 14, cause the tearing of the side wall 14 over its entire surface.

Cette solution présente donc les avantages suivants :

  • l'initiation du déchirement est facilitée ;
  • l'ouverture de l'emballage est réalisée facilement, sur une surface globale plus importante que dans l'art antérieur, puisque représentant la base 2 plus la surface d'une grande paroi latérale 14 et non la petite surface latérale 15 ;
  • l'emballage ouvert peut être saisi manuellement de manière conviviale, sans toucher à son contenu, par exemple en plaçant le pouce sur la surface intérieure de la base 2 déchirée et l'index sur la surface extérieure du couvercle 6 sur lequel repose toujours le contenu. Ce contenu peut ainsi être facilement saisi, soit en le démoulant dans une assiette, soit en le portant directement à la bouche ;
  • la forme de l'emballage contenant le fromage après son ouverture est telle qu'elle ne présente pas de recoin dans lequel pourrait rester coincer une partie du contenu.
This solution therefore has the following advantages:
  • the initiation of the tearing is facilitated;
  • the opening of the package is made easily, on a larger overall area than in the prior art, since representing the base 2 plus the surface of a large side wall 14 and not the small side surface 15;
  • the open package can be entered manually in a user-friendly manner, without affecting its contents, for example by placing the thumb on the inner surface of the torn base 2 and the index on the outer surface of the lid 6 on which the contents still rest. . This content can thus be easily grasped, either by unmolding it on a plate, or by bringing it directly to the mouth;
  • the shape of the package containing the cheese after opening is such that it has no corner in which could remain trapped part of the content.

Finalement, ce mode d'exécution de l'invention concerne plus particulièrement les emballages triangulaires ayant des parois latérales de dimensions différentes, grandes et petites.Finally, this embodiment of the invention relates more particularly to triangular packages having lateral walls of different sizes, large and small.

Les figures 5 à 8 illustrent un second mode d'exécution de l'invention, sur lesquelles des références identiques correspondent aux mêmes caractéristiques. Ce mode d'exécution diffère du mode précédent par l'emplacement des bandes de déchirement.The Figures 5 to 8 illustrate a second embodiment of the invention, in which identical references correspond to the same characteristics. This embodiment differs from the previous mode in the location of the tear strips.

Deux bandes de déchirement en aluminium ou polyester sont utilisées et disposées sur un film 1 en aluminium de forme équivalente à celui de la figure 1. Comme illustré sur la figure 5, ces deux bandes se rejoignent pour former une languette 37 faisant saillie au-delà de la partie latérale 14 du film 1, dans une zone plus proche de la partie d'angle 17 que de la partie 20. Les deux bandes de déchirement de cette languette 37 se séparent ensuite et traversent la paroi latérale 14 par respectivement deux parties 31 et 32. La première partie 31 traverse la base 2 au niveau de son angle O correspondant au centre du disque dont la portion est issue, puis se prolonge par une partie 33 sur la paroi latérale 13 sur une longueur correspondant à l'épaisseur du futur emballage terminé, illustré en figure 6. La seconde bande comprend une partie 35 prolongeant la partie 32, qui traverse la base 2 en longeant sensiblement son petit côté 5, puis qui se prolonge sur la paroi latérale 13 par une partie 34 sur une longueur correspondant à l'épaisseur du futur emballage terminé. La languette 37 fait saillie sur le couvercle 6, comme illustré sur la figure 6.Two tear strips of aluminum or polyester are used and arranged on an aluminum film 1 of equivalent shape to that of the figure 1 . As illustrated on the figure 5 these two bands meet to form a tongue 37 protruding beyond the side portion 14 of the film 1, in an area closer to the corner portion 17 than the Part 20. The two tear strips of this tongue 37 then separate and pass through the side wall 14 by two parts 31 and 32 respectively. The first part 31 passes through the base 2 at its angle O corresponding to the center of the disk whose portion is issued, then is extended by a portion 33 on the side wall 13 over a length corresponding to the thickness of the finished future packaging, illustrated in FIG. figure 6 . The second band comprises a portion 35 extending the portion 32, which passes through the base 2 substantially along its short side 5, and which extends on the side wall 13 by a portion 34 to a length corresponding to the thickness of the future finished package . The tongue 37 protrudes from the cover 6, as shown in FIG. figure 6 .

Les figures 7 et 8 illustrent l'ouverture de l'emballage. La traction sur la languette 37 provoque le déchirement de la quasi-totalité de la paroi latérale 14, puis la totalité de la surface de la base 2, et enfin la totalité de la surface de l'autre grande paroi latérale 13.The Figures 7 and 8 illustrate the opening of the packaging. The traction on the tongue 37 causes the tearing of almost the entire side wall 14, then the entire surface of the base 2, and finally the entire surface of the other large side wall 13.

Cette solution présente donc les avantages suivants :

  • l'ouverture de l'emballage est réalisée facilement, sur une surface globale plus importante que dans l'art antérieur, puisque représentant la base 2 plus la surface des deux grandes parois latérales 13,14 ;
  • l'emballage ouvert peut être saisi manuellement de manière conviviale, sans toucher à son contenu, qui peut être facilement saisi, soit en le démoulant dans une assiette soit en le portant directement à la bouche ;
  • la forme de l'emballage contenant le fromage après son ouverture est telle qu'elle ne présente pas de recoin dans lequel pourrait rester coincer une partie du fromage.
This solution therefore has the following advantages:
  • the opening of the package is made easily, on a larger overall area than in the prior art, since representing the base 2 plus the surface of the two large side walls 13,14;
  • the open package can be entered manually in a user-friendly manner, without affecting its contents, which can be easily grasped, either by unmolding it on a plate or by bringing it directly to the mouth;
  • the shape of the package containing the cheese after opening is such that it has no corner in which could remain trapped part of the cheese.

Finalement, l'invention concerne les emballages triangulaires en un matériau quelconque comme de l'aluminium ou du plastique, et permet une meilleure ouverture de ces emballages grâce au déchirement d'au moins la base et une surface importante des parois latérales. Elle comprend donc une disposition des bandes de déchirement pour définir une surface totale importante de parois latérales de la portion triangulaire qui se déchire. Cette surface est plus précisément définie par la surface comprise entre les deux bandes de déchirement. Dans le premier mode d'exécution, cette surface est importante car elle concerne la totalité d'une grande paroi latérale et dans le second mode d'exécution, cette surface est importante car elle concerne quasiment la totalité des deux grandes parois latérales. Toute autre combinaison intermédiaire pourrait convenir.Finally, the invention relates to triangular packages of any material such as aluminum or plastic, and allows a better opening of these packages through the tearing of at least the base and a large surface of the side walls. It therefore comprises an arrangement of tear strips to define a large total surface of the side walls of the triangular portion that tears. This surface is more precisely defined by the area between the two tear strips. In the first embodiment, this surface is important because it concerns the entire of a large side wall and in the second embodiment, this surface is important because it concerns almost all of the two large side walls. Any other intermediate combination may be suitable.

Dans le cas particulier des portions provenant de la découpe d'un disque, sensiblement triangulaire isocèles, la solution repose sur deux bandes de déchirement qui ne sont plus identiques, ne sont plus réparties de manière symétrique sur la portion comme dans l'art antérieur, mais dont une bande traverse la base en longeant sensiblement le petit côté arrondi 5, pour permettre le déchirement d'au moins une grande paroi latérale.In the particular case of the portions coming from the cutting of a disk, substantially triangular isosceles, the solution rests on two tear strips which are no longer identical, are no longer distributed symmetrically over the portion as in the prior art, but a band passes through the base substantially along the small rounded side 5, to allow the tearing of at least one large side wall.

Enfin, l'invention porte aussi sur un procédé de fabrication d'un emballage qui comprend les étapes suivantes :

  1. a) découpe d'un film 1 comprenant une base 2 et trois parties latérales de dimensions différentes 13, 14, 15,
  2. b) fixation de deux bandes de déchirement sur le film 1, se rejoignant sur une extrémité pour former une languette 27, 37, traversant la base 2 et s'étendant sur des parois latérales 14, 13 pour délimiter une zone de déchirement importante de ces parois latérales,
  3. c) pliage du film 1 pour former une coquille,
  4. d) remplissage de la coquille par un contenu comme du fromage,
  5. e) pose d'un couvercle 6 sur ce contenu et rabat des parois latérales sur ce couvercle.
Finally, the invention also relates to a method of manufacturing a package which comprises the following steps:
  1. a) cutting a film 1 comprising a base 2 and three lateral portions of different dimensions 13, 14, 15,
  2. b) fixing two tear strips on the film 1, joining at one end to form a tongue 27, 37, passing through the base 2 and extending on the side walls 14, 13 to delimit a large tear zone of these side walls,
  3. c) folding the film 1 to form a shell,
  4. d) filling the shell with contents such as cheese,
  5. e) laying a lid 6 on this content and flap side walls on the cover.

En remarque, les étapes a) et b) peuvent être inversées dans le temps, les bandes étant d'abord disposées sur le film appartenant à un rouleau avant son découpage dans ce rouleau.As a remark, steps a) and b) can be reversed in time, the strips being first arranged on the film belonging to a roll before it is cut into this roll.
