Description

La présente invention concerne un emballage de conditionnement d'un produit alimentaire selon le préambule de la revendication 1.The present invention relates to a packaging for packaging a food product according to the preamble of claim 1.

L'invention s'applique en particulier au conditionnement de fromage fondu.The invention applies in particular to the packaging of processed cheese.

Dans tout ce qui suit, on entend par emballages à fonds sensiblement triangulaires les emballages dont les fonds sont effectivement triangulaires avec des côtés rectilignes, mais également ceux dont les fonds présentent un côté courbe et possèdent donc une forme en secteur de disque.In what follows, packaging with substantially triangular bottoms means packaging whose funds are actually triangular with straight sides, but also those whose funds have a curved side and therefore have a disc sector shape.

FR-2 597 436 décrit un emballage du type précité pour conditionner une portion de fromage fondu. Cet emballage est constitué de deux feuilles d'aluminium. Les moyens de guidage sont des bandes rapportées sur la première feuille. Les premières extrémités des bandes de guidage des déchirures se chevauchent pour former la languette de saisie. FR-2 597 436 describes a package of the aforementioned type for packaging a portion of processed cheese. This package consists of two aluminum sheets. The guide means are strips attached to the first sheet. The first ends of the tear guide strips overlap to form the gripping tab.

EP-803 439 a proposé de remplacer, dans des emballages de conditionnement de fromage fondu, l'aluminium par du polypropylène pour faciliter le recyclage. L'emballage décrit dans ce document est constitué de trois feuilles et l'ouverture s'effectue par déchirement des parois latérales et du talon de l'emballage. EP-803,439 proposed to replace aluminum in polypropylene packaging packaging with processed cheese to facilitate recycling. The package described in this document consists of three sheets and the opening is effected by tearing the side walls and the heel of the package.

Un tel mode d'ouverture n'est pas entièrement satisfaisant dans la mesure où il ne dégage que les parois latérales et le talon de la portion de fromage fondu. Le consommateur doit donc toucher le fromage pour enlever le couvercle ou le fond de l'emballage avant de pouvoir consommer le produit.Such an opening method is not entirely satisfactory insofar as it releases only the side walls and the heel of the processed cheese portion. The consumer must touch the cheese to remove the lid or the bottom of the packaging before consuming the product.

La structure d'emballage et le mode d'ouverture qui sont décrits dans FR-2 597 436 sont plus satisfaisants pour les consommateurs. Toutefois, une telle structure ne peut pas être utilisée avec un matériau tel que du polypropylène qui est beaucoup plus résistant que l'aluminium.The packaging structure and the mode of opening which are described in FR-2 597 436 are more satisfying for consumers. However, such a structure can not be used with a material such as polypropylene which is much stronger than aluminum.

Ainsi, la propagation des déchirures, telle qu'elle est prévue dans FR-2 597 436 , ne pourrait pas se produire dans une feuille de polypropylène.Thus, the propagation of tears, as provided for in FR-2 597 436 , could not occur in a polypropylene sheet.

En outre, il est délicat d'obtenir un chevauchement parfait des extrémités des bandes, comme décrit dans FR-2 597 436 , et il est fréquent en pratique qu'un consommateur ne saisisse qu'une seule de celles-ci. Le consommateur ne peut alors obtenir une ouverture intégrale de l'emballage, des parties de la portion de fromage fondu restant dans l'emballage et le consommateur devant alors toucher le fromage pour le dégager complètement de l'emballage.In addition, it is difficult to obtain a perfect overlap of the ends of the strips, as described in FR-2 597 436 and it is common in practice for a consumer to enter only one of these. The consumer can not then obtain a full opening of the package, parts of the portion of processed cheese remaining in the package and the consumer must then touch the cheese to release it completely from the package.

Un but de l'invention est de résoudre ces problèmes en fournissant un emballage du type précité qui, tout en étant plus facilement recyclable, puisse être ouvert de manière simple et satisfaisante pour livrer accès à l'intégralité du produit conditionné dans l'emballage.An object of the invention is to solve these problems by providing a packaging of the aforementioned type which, while being more easily recyclable, can be opened in a simple and satisfactory manner to provide access to the entire packaged product.

A cet effet, l'invention a pour objet un emballage selon la revendication 1.For this purpose, the subject of the invention is a package according to claim 1.

Selon des modes particuliers de réalisation, l'emballage peut comprendre l'une ou plusieurs des caractéristiques des revendications 2 à 6.According to particular embodiments, the packaging may comprise one or more of the features of claims 2 to 6.

L'invention a en outre pour objet un ensemble selon la revendication 7. Selon un mode particulier de réalisation, l'ensemble peut comprendre la caractéristique facultative présentée dans la revendication 8.The invention further relates to an assembly according to claim 7. According to a particular embodiment, the assembly may comprise the optional feature presented in claim 8.

L'invention a également pour objet une feuille selon la revendication 9.The invention also relates to a sheet according to claim 9.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels :

  • la figure 1 est une vue schématique en plan d'une première feuille d'un emballage selon l'invention avant pliage,
  • les figures 2 et 3 sont des vues schématiques en perspective illustrant deux étapes successives de la réalisation de l'emballage à partir de la feuille de la figure 1,
  • la figure 4 est une vue schématique en perspective de l'emballage achevé,
  • les figures 5 et 6 sont des vues schématiques représentant deux étapes successives de l'ouverture de l'emballage de la figure 4.
The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings, in which:
  • the figure 1 is a schematic plan view of a first sheet of a package according to the invention before folding,
  • the Figures 2 and 3 are schematic views in perspective illustrating two successive stages of the realization of the packaging from the sheet of the figure 1 ,
  • the figure 4 is a schematic perspective view of the completed package,
  • the Figures 5 and 6 are schematic views representing two successive stages of the opening of the packaging of the figure 4 .

La feuille 1 représentée sur la figure 1 est une feuille de polypropylène destinée au conditionnement d'une portion de fromage fondu à base en secteur de disque.The sheet 1 shown on the figure 1 is a polypropylene sheet for packaging a portion of processed cheese based disc sector.

Pour former un emballage, et comme représenté sur la figure 2, la feuille 1 est conformée en un godet 2 par pliage, suivant les lignes représentées en pointillés sur la figure 1. -To form a package, and as depicted on the figure 2 , the sheet 1 is shaped into a cup 2 by folding, along the lines represented in dashed lines on the figure 1 . -

Le godet 2 comprend un fond 3 en forme de secteur de disque délimité par deux bords latéraux 5 et 7 et un bord en arc de cercle 8. Perpendiculairement au plan du fond 3, le godet 2 comprend deux parois latérales 9 et 11, qui s'étendent le long des bords rectilignes 5 et 7, et une paroi courbe formant talon 13 qui s'étend le long du bord en arc de cercle 8. Les parois latérales 9 et 11 se rejoignent le long d'une pointe 15 opposée au talon 13.The bucket 2 comprises a bottom 3 in the form of a sector of disk delimited by two lateral edges 5 and 7 and an arcuate edge 8. Perpendicularly to the plane of the bottom 3, the bucket 2 comprises two lateral walls 9 and 11, which are extend along the straight edges 5 and 7, and a curved heel wall 13 which extends along the arcuate edge 8. The side walls 9 and 11 meet along a tip 15 opposite the heel 13.

Les parois latérales 9 et 11 et le talon 13 sont prolongés par des rabats, respectivement 17, 19 et 21, destinés à être rabattus suivant des lignes de pliages 23, 25 et 27, lors de la fermeture de l'emballage.The side walls 9 and 11 and the heel 13 are extended by flaps, respectively 17, 19 and 21, intended to be folded along fold lines 23, 25 and 27, when closing the package.

La feuille 1 avant pliage comporte en outre des zones intermédiaires 29, 31 et 33 disposées respectivement entre les parois 9 et 11 et leurs rabats 17 et 19, entre la paroi 9 et le talon 13 et leurs rabats 17 et 21, et entre le talon 13 et la paroi 11 et leurs rabats 21 et 19. Les bords latéraux 35 et 37 du talon 13 et du rabat 21 prolongent les bords latéraux 5 et 7 du fond 3. Le ra bat 21 comporte une pointe centrale 39 qui fait saillie à l'opposé de la zone intermédiaire 29.The sheet 1 before folding further comprises intermediate zones 29, 31 and 33 disposed respectively between the walls 9 and 11 and their flaps 17 and 19, between the wall 9 and the heel 13 and their flaps 17 and 21, and between the heel 13 and the wall 11 and their flaps 21 and 19. The lateral edges 35 and 37 of the heel 13 and the flap 21 extend the side edges 5 and 7 of the bottom 3. The bat 21 has a central tip 39 which projects from opposite of the intermediate zone 29.

Comme illustré par la figure 1, deux découpes 41 et 43 sont ménagées dans la feuille 1 entre le bord extérieur 45 de la pointe 39 et les bords extérieurs 47 et 48 du reste du rabat 21. Des lignes de pliage 49 et 50 s'étendent depuis les découpes 41 et 43 jusqu'aux points d'intersection entre la ligne de pliage courbe 27 et les bords latéraux 35 et 37 du talon 13. Avant pliage de la feuille 1, les lignes de pliage 49 et 50 sont inclinées par rapport aux bords latéraux 35 et 37.As illustrated by figure 1 two cutouts 41 and 43 are formed in the sheet 1 between the outer edge 45 of the point 39 and the outer edges 47 and 48 of the remainder of the flap 21. Fold lines 49 and 50 extend from the cutouts 41 and 43 to the points of intersection between the curved fold line 27 and the side edges 35 and 37 of the heel 13. Before folding of the sheet 1, the fold lines 49 and 50 are inclined with respect to the side edges 35 and 37.

La feuille 1 est également munie, du côté destiné à former la face interne du godet 2, de deux bandes 51a et 51b de guidage de déchirures. Les deux bandes 51a et 51b sont sensiblement symétriques par rapport à un axe médian A de la feuille 1. Les bandes 51a et 51b ont été thermosoudées à la fois entre elles et sur la feuille 1. Les bandes 51 a et 51 b sont par exemple réalisées en polypropylène.The sheet 1 is also provided, on the side intended to form the inner face of the cup 2, two strips 51a and 51b tear guide. The two strips 51a and 51b are substantially symmetrical with respect to a median axis A of the sheet 1. The strips 51a and 51b have been heat-sealed at the same time between them and on the sheet 1. The strips 51a and 51b are for example made of polypropylene.

Comme illustré par la figure 1, chacune des bandes 51 a, 51 b comporte une première extrémité rectiligne 53a, 53b s'étendant depuis la pointe 39 dans le rabat 21 et dans le talon 13, jusqu'au bord latéral 35, 37. Ensuite, les bandes 51 a, 51 b s'étendent rectilignement le long des bords latéraux 5 et 7 et se terminent par des secondes extrémités 55a et 55b, au-delà d'un point d'intersection 57. Les extrémités 55a et 55b s'étendent dans les parois latérales 9 et 11 et dans la zone intermédiaire 29.As illustrated by figure 1 each of the strips 51a, 51b has a first rectilinear end 53a, 53b extending from the point 39 in the flap 21 and in the heel 13, to the side edge 35, 37. Then, the strips 51a, 51 b extend straight along the side edges 5 and 7 and terminate in second ends 55a and 55b, beyond a point of intersection 57. The ends 55a and 55b extend in the side walls 9 and 11 and in the intermediate zone 29.

Les premières extrémités 53a et 53b sont disposées à proximité respectivement des découpes 41 et 43 et sont espacées latéralement l'une de l'autre.The first ends 53a and 53b are disposed close to the cutouts 41 and 43, respectively, and are laterally spaced from one another.

Avant pliage de la feuille 1, les extrémités 53a et 53b convergent l'une vers l'autre à l'opposé du point d'intersection 57 et délimitent entre elles, dans le rabat 21, une languette de traction 58 comprenant la pointe 39 et qui s'étend sensiblement sur toute la largeur du rabat 21. Après les premières extrémités 53a et 53b, les deux bandes 51a et 51 b convergent l'une vers l'autre jusqu'au point d'intersection 57, avant de diverger à nouveau.Before folding of the sheet 1, the ends 53a and 53b converge towards each other opposite the point of intersection 57 and delimit between them, in the flap 21, a pull tab 58 comprising the tip 39 and which extends substantially over the entire width of the flap 21. After the first ends 53a and 53b, the two strips 51a and 51b converge towards one another to the point of intersection 57, before diverging again .

Pour obtenir le godet 2 de la figure 2 à partir de la feuille 1, les zones intermédiaires 31 et 33 reliant les parois latérales 9 et 11 et le talon 13 sont pliées à partir du fond 3 en leur milieu le long des lignes 59 et 61, visibles sur la figure 1. Les volets triangulaires ainsi formés 63 et 65 sont repliés respectivement sur les parois latérales 9 et 11 le long des bords latéraux 35 et 37 du talon 13. Quant à la zone intermédiaire 29 comportant l'extrémité des bandes 51a et 51 b, elle est également pliée en son milieu le long d'une ligne de pliage 67 (figure 1) et le volet triangulaire ainsi formé 69 est replié sur la paroi latérale 9. Les secondes extrémités 55a et 55b des bandes 51 a et 51 b s'étendent dans le volet 69.To get the bucket 2 of the figure 2 from the sheet 1, the intermediate areas 31 and 33 connecting the side walls 9 and 11 and the heel 13 are folded from the bottom 3 in their middle along the lines 59 and 61, visible on the figure 1 . The triangular shutters thus formed 63 and 65 are folded respectively on the side walls 9 and 11 along the lateral edges 35 and 37 of the heel 13. As for the intermediate zone 29 comprising the ends of the strips 51a and 51b, it is also folded in the middle along a fold line 67 ( figure 1 ) and the triangular shutter thus formed 69 is folded over the side wall 9. The second ends 55a and 55b of the strips 51a and 51b extend in the shutter 69.

Ces différentes opérations de pliage sont par exemple réalisées à chaud, comme décrit dans EP-803 439 , afin d'obtenir une déformati on plastique du polypropylène de la feuille 1. Ce pliage à chaud peut, par exemple, être mis en oeuvre dans une cheminée de pliage dans laquelle on pousse la feuille 1. On peut également réaliser préalablement tout ou partie des lignes de pliage par déformation mécanique de la feuille 1, par exemple grâce à une molette.These various folding operations are for example carried out hot, as described in EP-803,439 in order to obtain a plastic deformation of the polypropylene of the sheet 1. This hot folding can, for example, be implemented in a folding stack in which the sheet 1 is pushed. fold lines by mechanical deformation of the sheet 1, for example by means of a wheel.

Dans le godet 2 ainsi obtenu est coulée à chaud une quantité déterminée de fromage fondu sur une hauteur égale à la hauteur des parois latérales 9 et 11 et du talon 13, afin de constituer une portion 70 visible sur la figure 2.In the cup 2 thus obtained, a quantity of melted cheese is hot cast on a height equal to the height of the side walls 9 and 11 and the heel 13, in order to constitute a portion 70 visible on the figure 2 .

Une seconde feuille 71, de dimensions correspondant à celles du fond 3, est déposée sur la portion 70. Cette seconde feuille 71 forme couvercle de fermeture du godet 2. Elle est, par exemple, réalisée également en polypropylène. Ensuite, et comme illustré par la figure 3, le rabat 21 est rabattu sur la feuille 71 et scellé sur celle-ci de part et d'autre des découpes 41 et 43 en laissant libre la pointe 58.A second sheet 71, of dimensions corresponding to those of the bottom 3, is deposited on the portion 70. This second sheet 71 forms the closure lid of the cup 2. It is, for example, also made of polypropylene. Then, as illustrated by figure 3 , the flap 21 is folded over the sheet 71 and sealed thereon on both sides of the cutouts 41 and 43 leaving free the tip 58.

Les rabats 17 et 19 sont ensuite rabattus et scellés sur la seconde feuille 71, comme illustré par la figure 4.The flaps 17 and 19 are then folded and sealed on the second sheet 71, as illustrated by the figure 4 .

On obtient ainsi un ensemble 73 comprenant un emballage 75, constitué des feuilles 1 et 71, et la portion de fromage fondu 70 conditionnée dans l'emballage 75.An assembly 73 is thus obtained comprising a package 75, consisting of sheets 1 and 71, and the portion of processed cheese 70 packaged in package 75.

L'ouverture de l'emballage 75 est réalisée comme illustré par les figures 5 et 6. Le consommateur appuie le pouce et l'index d'une main sur les deux parois latérales 9 et 11 et saisit de l'autre main la languette de traction 58. En tirant sur cette languette 58 d'un seul mouvement, il amorce des déchirures au niveau des découpes 41 et 43. La traction se poursuivant, les déchirures se propagent le long des bandes 51 a et 51 b qui les guident. Le consommateur peut ainsi libérer dans son intégralité le talon 77 de la portion 70, puis la grande face triangulaire 79 (figure 6) jusqu'au moment où les secondes extrémités 55a et 55b des bandes 51a et 51b provoquent la déchirure le long de la pointe 15 libérant ainsi totalement les parois latérales 9 et 11, qu'il ne restera qu'à rabattre comme illustré par les flèches 81 sur la figure 6.The opening of the packaging 75 is carried out as illustrated by the Figures 5 and 6 . The consumer presses the thumb and forefinger of one hand on the two side walls 9 and 11 and grasps with the other hand the pull tab 58. By pulling on this tongue 58 in one movement, he initiates tears at the cutouts 41 and 43. As the traction continues, the tears propagate along the bands 51a and 51b which guide them. The consumer can thus release in its entirety the heel 77 of the portion 70, then the large triangular face 79 ( figure 6 ) until the second ends 55a and 55b of the strips 51a and 51b cause the tear along the tip 15 thus completely releasing the side walls 9 and 11, it only remains to fold as illustrated by the arrows 81 on the figure 6 .

L'emballage 75 peut donc être ouvert en livrant accès à l'intégralité de la portion 70, sans qu'il ne soit nécessaire de toucher la portion 70. En outre, la rigidité du matériau utilisé pour constituer la feuille 1 permet aux bandes 51a et 51 b d'être espacées l'une de l'autre tout en permettant une ouverture satisfaisante. Le consommateur bénéficie donc d'une languette de saisie 58 de dimensions importantes et ne risque pas, comme dans l'emballage de FR-2 597 436 , de n'utiliser qu'une seule des deux bandes de guidage des déchirures.The package 75 can therefore be opened by providing access to the entire portion 70, without the need to touch the portion 70. In addition, the rigidity of the material used to form the sheet 1 allows the strips 51a and 51b to be spaced from each other while allowing satisfactory opening. The consumer thus benefits from a gripping tongue 58 of large dimensions and does not risk, as in the packaging of FR-2 597 436 , to use only one of the two tears guiding strips.

En outre, le trajet de guidage des déchirures ne présente pas de changement important de direction comme dans FR-2 597 436 . Ainsi, malgré la résistance du matériau utilisé pour constituer la feuille 1, les déchirures amorcées par les découpes 41 et 43 se propagent de manière satisfaisante.In addition, the tear guide path does not show a significant change of direction as in FR-2 597 436 . So despite the resistance of the material used to form the sheet 1, the tears initiated by the cuts 41 and 43 propagate satisfactorily.

On notera également que la largeur de la languette de traction 58 et le mode d'ouverture choisi conduit à une ouverture rationnelle et susceptible d'être mise en oeuvre par pratiquement tous les consommateurs.Note also that the width of the pull tab 58 and the chosen opening mode leads to a rational opening and can be implemented by virtually all consumers.

En outre, le guidage des déchirures étant assuré par des bandes 51 a et 51 b de faible largeur, le coût global de l'emballage 75 reste faible et celui-ci présente une bonne étanchéité.In addition, the guide of the tears being provided by strips 51a and 51b of small width, the overall cost of the package 75 remains low and it has a good seal.

On notera que les principes ci-dessus peuvent être utilisés avec la feuille 1 et/ou la feuille 71 réalisée(s) en d'autres matières plastiques que du polypropylène.It should be noted that the above principles can be used with sheet 1 and / or sheet 71 made from other plastics than polypropylene.

De plus, les bandes 51a et 51b peuvent être remplacées par des moyens de guidage d'autres natures.In addition, the strips 51a and 51b can be replaced by guide means of other kinds.

Ainsi, il peut s'agir d'affaiblissements locaux de la première feuille 1, obtenus par exemple grâce à une molette ou un faisceau laser.Thus, it may be local weakenings of the first sheet 1, obtained for example by means of a wheel or a laser beam.
