Description

La présente invention concerne un ensemble comprenant une portion de fromage fondu et un emballage enveloppant étroitement ladite portion, l'emballage comprenant un élément comprenant lui-même une feuille enveloppant étroitement ladite portion et en contact avec celle-ci, et des moyens d'amorçage d'une déchirure pour que la feuille se déchire le long d'au moins une ligne de déchirure lors de la traction d'une languette de saisie de l'élément.The present invention relates to an assembly comprising a portion of processed cheese and wrapping tightly wrapped portion, the package comprising an element including itself a sheet tightly enclosing said portion and in contact therewith, and means for priming a tear so that the sheet is torn along at least one tear line when pulling a pull tab of item.

On entend par fromages fondus, les produits obtenus par la fonte à chaud, en présence ou non de sels de fonte, de fromages seuls ou en mélange avec d'autres matières premières laitières, beurre, poudre de lait, de lactosérum, matière grasse laitière anhydre, concentrés protéiques, etc). Le terme de fromage fondu comprend également les produits où les matières premières fromagères ou laitières sont remplacés partiellement ou totalement par des matières végétales (matières grasses ou protéines).Melted cheese means products obtained by melting hot, with or without melting salts, cheese alone or mixture with other dairy raw materials, butter, milk powder, whey, anhydrous milk fat, protein concentrates, etc.). The term processed cheese also includes products where the materials first cheese or milk products are replaced partially or totally by vegetable matter (fat or protein).

Généralement, les portions de fromage fondu, de consistance pâteuse, sont conditionnées étroitement dans des emballages réalisés à partir de plusieurs éléments qui comprennent des feuilles d'aluminium.Generally, the portions of processed cheese, of consistency pasty, are packaged tightly in packaging made from of several elements that include aluminum sheets.

Comme décrit par exemple dans les documents EP-242 268 et EP-340 093, dans un ensemble du type précité, un élément de l'emballage comprend habituellement une feuille et un organe de déchirement rapporté par soudage sur la feuille. Une extrémité de l'organe de déchirement dépasse de la feuille pour former la languette de saisie.As described for example in documents EP-242 268 and EP-340 093, in a set of the aforementioned type, an element of the packaging usually includes a leaf and a reported tearing member by welding on the sheet. One end of the tearing member protrudes of the sheet to form the catch tab.

L'organe de déchirement renforce localement la feuille si bien qu'il permet, lorsqu'un consommateur tire sur la languette de saisie, une amorce de déchirure de la feuille le long des bords extérieurs de l'organe de déchirement. Lorsque le consommateur continue à tirer sur la languette de saisie, l'organe de déchirement guide le long de ses bords extérieurs les déchirures de la feuille ainsi amorcées. Ces organes de déchirement sont généralement relativement longs pour pouvoir guider les déchirures sur toute la longueur des lignes de déchirure.The tearing organ locally strengthens the leaf so well it allows, when a consumer pulls on the input tab, a tear initiation of the leaf along the outer edges of the organ tear. When the consumer continues to pull the tab of grasping, the tearing member guides along its outer edges the tearing of the sheet thus initiated. These tearing organs are generally relatively long to be able to guide the tears on any the length of the tear lines.

Si l'ouverture de tels emballages est généralement satisfaisante, leur fabrication pose de nombreux problèmes parmi lesquels ceux liés à la découpe, au positionnement et au soudage des organes de déchirement sur les feuilles des éléments d'emballage.If the opening of such packaging is generally satisfactory, their manufacture poses many problems, among which those related to cutting, positioning and welding of tearing members on the sheets of packaging elements.

En effet, la forme et le positionnement des organes de déchirement sur les éléments d'emballage doivent être relativement précis pour que l'ouverture des emballages formés soit satisfaisante. Indeed, the shape and positioning of the organs of tearing on the packaging elements must be relatively accurate so that the opening of the packages formed is satisfactory.

Un but de l'invention est donc de fournir un ensemble du type précité qui soit plus simple et plus économique à réaliser.An object of the invention is therefore to provide a set of the type above mentioned which is simpler and more economical to achieve.

A cet effet, l'invention a pour objet un ensemble du type précité, caractérisé en ce qu'au moins une première partie de ladite ou de chaque ligne de déchirure est définie par ou dans un matériau de la feuille.For this purpose, the subject of the invention is an assembly of the aforementioned type, characterized in that at least a first portion of said or each tear line is defined by or in a material of the sheet.

  • ledit élément d'emballage forme au moins ledit manchon, ladite ou chaque première partie de ligne de déchirure s'étendant au voisinage du fond ou du couvercle.
According to particular embodiments, the assembly may comprise one or more of the following characteristics, taken in isolation or in any technically possible combination:
  • the sheet comprises a material whose tear strength in the direction of the or each first tear line portion is less than its tear strength in a direction orthogonal to the direction of the or each first tear line portion;

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 en plan d'un élément selon l'invention,
  • les figures 2 à 6 sont des vues schématiques en perspective illustrant des étapes successives d'un procédé de conditionnement d'une portion de fromage fondu à partir de l'élément de la figure 1,
  • la figure 7 est une vue schématique en perspective, partiellement arrachée, illustrant l'ensemble comportant la portion de fromage fondu et l'emballage ainsi obtenu,
  • la figure 8 est une vue schématique en perspective, partiellement arrachée, illustrant l'ouverture de l'emballage de la figure 7,
  • la figure 9 est une vue analogue à la figure 1 illustrant un autre mode de réalisation de l'invention.
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:
  • FIG. 1 is a plan view of an element according to the invention,
  • FIGS. 2 to 6 are diagrammatic perspective views illustrating successive steps of a method of packaging a portion of processed cheese from the element of FIG. 1,
  • FIG. 7 is a diagrammatic perspective view, partly broken away, illustrating the assembly comprising the portion of processed cheese and the packaging thus obtained,
  • FIG. 8 is a diagrammatic perspective view, partially broken away, illustrating the opening of the package of FIG. 7,
  • Figure 9 is a view similar to Figure 1 illustrating another embodiment of the invention.

La figure 1 représente un élément 1 pour former un emballage de conditionnement d'une portion de fromage fondu.Figure 1 shows an element 1 to form a package of a portion of processed cheese.

L'élément 1 est constitué d'une feuille 2 rectangulaire allongée suivant une direction longitudinale. Cette feuille 2 est réalisée par exemple en un matériau orienté principalement longitudinalement, c'est à dire parallèlement aux grands côtés 3 et 4 de la feuille 2.Element 1 consists of an elongated rectangular sheet 2 in a longitudinal direction. This sheet 2 is made for example in a material oriented mainly longitudinally, ie parallel to the long sides 3 and 4 of the sheet 2.

Ainsi, la feuille 2 offre une résistance au déchirement selon sa direction longitudinale inférieure à sa résistance au déchirement selon sa direction transversale.Thus, the sheet 2 offers resistance to tearing according to its longitudinal direction less than its tear resistance according to its transverse direction.

Par conséquent la feuille 2 présente la propriété de se déchirer, après amorce, préférentiellement de façon sensiblement rectiligne le long de sa direction longitudinale.Therefore sheet 2 has the property of tearing, after primer, preferably substantially rectilinearly along its longitudinal direction.

On a ménagé, depuis le petit côté gauche 5 de la feuille 2, des entailles longitudinales 6 de faible longueur. Ces entailles 6 ont par exemple une longueur comprise entre 1 et 3 mm.From the small left side 5 of sheet 2, longitudinal notches 6 of short length. These cuts 6 have for example a length of between 1 and 3 mm.

Les entailles 6 sont espacées transversalement l'une de l'autre et disposées de manière avantageusement symétrique par rapport à l'axe longitudinal médian de la feuille 2. Les entailles 6 sont disposées chacune à faible distance d'un des grands côtés 3 et 4 de la feuille 2.The notches 6 are spaced transversely from one another and arranged advantageously symmetrically with respect to the axis medial length of the sheet 2. The notches 6 are each arranged at short distance from one of the long sides 3 and 4 of the sheet 2.

Du fait de l'orientation-du matériau de la feuille 2, les lignes longitudinales 8 (en traits mixtes à deux tirets sur la figure 1), qui prolongent les entailles 6 dans la feuille 2, sont des lignes prédéterminées de déchirure de l'élément 2. Due to the orientation of the material of sheet 2, the lines longitudinal lines 8 (in phantom with two dashes in Figure 1), which extend the notches 6 in the sheet 2, are predetermined lines of tearing of element 2.

Ces lignes de déchirure 8 délimitent entre elles une bande 9 centrale et longitudinale qui forme, entre les entailles 6, une languette de saisie 10 de forme rectangulaire. Les extrémités intérieures 11 des entailles 6 délimitent les coins intérieurs de la languette de saisie 10.These tear lines 8 delimit between them a strip 9 central and longitudinal which forms, between the cuts 6, a tongue of seizure 10 of rectangular shape. The inner ends 11 of the notches 6 define the inner corners of the gripping tab 10.

Pour former un emballage de conditionnement d'une portion de fromage fondu, on vient, comme illustré par la flèche 12 sur la figure 2, enrouler l'élément 1 autour d'un mandrin 13 de forme cylindrique d'axe A et à base en secteur de disque.To form a packaging package of a portion of melted cheese, one comes, as illustrated by the arrow 12 in Figure 2, winding the element 1 about a mandrel 13 of cylindrical shape of axis A and base in disk sector.

Ainsi, on obtient un manchon 14 de forme correspondante, visible sur les figures 3 et 4. Ce manchon 14 présente une pointe 15 et un talon courbe 16. L'élément 1 se recouvre lui-même au voisinage du talon 16 sur une faible partie de la longueur d'une face latérale 17 du manchon 14, cette face 17 reliant la pointe 15 au talon 16. Le petit côté 5 de la feuille 2 est situé dans le prolongement de la face latérale 17 au-delà de l'arête 18 reliant le talon 16 à la face latérale 17. Ainsi, la languette de saisie 10 est en saillie par rapport au manchon 14, au-delà de l'arête 18, dans le prolongement de la face latérale 17.Thus, a sleeve 14 of corresponding shape is obtained, visible in Figures 3 and 4. This sleeve 14 has a tip 15 and a curved heel 16. Element 1 overlaps itself in the vicinity of the heel 16 on a small part of the length of a lateral face 17 of the sleeve 14, this face 17 connecting the tip 15 to the heel 16. The short side 5 of the sheet 2 is located in the extension of the lateral face 17 beyond the connecting edge 18 the heel 16 to the side face 17. Thus, the gripping tongue 10 is projecting relative to the sleeve 14, beyond the edge 18, in the extension of the side face 17.

Le mandrin 13 est alors légèrement retiré axialement du manchon 14 de sorte que le rebord 19 du manchon 14, délimité par le grand côté 3 de la feuille 2 et la ligne de déchirure 8 voisine, dépasse du mandrin 13.The mandrel 13 is then slightly withdrawn axially from the sleeve 14 so that the rim 19 of the sleeve 14, delimited by the large side 3 of the sheet 2 and the tear line 8 adjacent, exceeds the mandrel 13.

Comme illustré par la figure 4, on rabat alors le rebord 19 du manchon 14 sur le mandrin 13 par pliage sensiblement le long de la ligne de déchirure 8 voisine.As illustrated in FIG. 4, flange 19 sleeve 14 on the mandrel 13 by folding substantially along the line of tear 8 neighbor.

On vient ensuite sceller un panneau de fond 20, de forme en secteur de disque correspondant à celle du mandrin 13, contre le rebord 19 rabattu du manchon 14. Ce panneau 20 est par exemple réalisé dans le même matériau que la feuille 2.It is then sealed a bottom panel 20, shaped in form disc sector corresponding to that of the mandrel 13, against the flange 19 folded sleeve 14. This panel 20 is for example made in the same material as sheet 2.

On obtient ainsi un godet 21, représenté sur la figure 5 après retournement par rapport à la figure 4, et après retrait axial complet du mandrin 13.This gives a bucket 21, shown in FIG. reversal with respect to FIG. 4, and after complete axial removal of the mandrel 13.

Le godet 21 est alors rempli partiellement de fromage fondu 22 en laissant le rebord supérieur 23 du manchon 14, délimité par le grand côté 4 de la feuille 2 et la ligne de déchirure 8 voisine, dépasser depuis la surface supérieure du fromage 22 contenu dans le godet 21.The bucket 21 is then partially filled with processed cheese 22 leaving the upper edge 23 of the sleeve 14, delimited by the long side 4 of the sheet 2 and the tear line 8 next, to pass from the surface superior cheese 22 contained in the bucket 21.

Ce fromage fondu 22 forme alors une portion, de forme cylindrique d'axe A et de base en secteur de disque, et contenue dans le godet 21. This melted cheese 22 then forms a portion, of shape cylindrical axis A and basic disk sector, and contained in the bucket 21.

On vient ensuite introduire un panneau de couvercle 24 de forme en secteur de disque correspondant à celle du mandrin 13 dans l'extrémité supérieure libre du manchon 14. Ce panneau 24 est par exemple réalisé dans le même matériau que la feuille 2. Le panneau de couvercle 24 est alors appliqué sur la surface supérieure de la portion de fromage fondu 22.We then introduce a cover panel 24 of form in disk sector corresponding to that of the mandrel 13 in the end free upper sleeve 14. This panel 24 is for example made in the same material as the sheet 2. The cover panel 24 is then applied to the upper surface of the portion of processed cheese 22.

Comme illustré par la figure 6, on rabat alors le rebord supérieur 23 du manchon 14 sur le panneau de couvercle 24 par pliage de la feuille 2 sensiblement le long de la ligne de déchirure 8 voisine. On scelle ensuite ce rebord 23 sur le panneau de couvercle 24. Dans une variante non représentée, le scellage du panneau de couvercle 24 sur le manchon 14 est réalisé en scellant un rebord du panneau 24, replié vers l'extérieur, sur le rebord 23, par exemple à l'aide de mâchoires de scellage mobiles radialement par rapport à l'axe A. Le panneau de fond 20 peut également être scellé de manière analogue sur le manchon 14 pour former le godet 21.As illustrated in FIG. 6, the upper flange is then folded down 23 of the sleeve 14 on the cover panel 24 by folding the sheet 2 substantially along the adjacent tear line 8. We then seal flange 23 on the cover panel 24. In a variant not shown, the sealing of the cover panel 24 on the sleeve 14 is made by sealing a flange of the panel 24, bent outwards, on the flange 23, for example using radially movable sealing jaws with respect to the axis A. The bottom panel 20 may also be sealed with analogously on the sleeve 14 to form the bucket 21.

Comme illustré par la figure 7, on obtient ainsi un ensemble 25 comprenant un emballage 26 et une portion de fromage fondu 22 étroitement enveloppée par l'emballage 26 et visible grâce à l'arrachement de la figure 7. L'emballage 26, et en particulier la bande centrale 9 de la feuille 2, est directement en contact de la portion 22. L'emballage 26 a une forme cylindrique d'axe A et de base en secteur de disque. Cette forme est délimitée par la bande centrale 9 de la feuille 2 fermée à ses extrémités par un fond 27, formé par le rebord 19 de la feuille 2 et par le panneau de fond 20, et par un couvercle 28, formé par le rebord 23 de la feuille 2 et par le panneau de couvercle 24.As illustrated by FIG. 7, a set 25 is thus obtained. comprising a package 26 and a portion of processed cheese 22 closely wrapped by the package 26 and visible through the tearing of Figure 7. The package 26, and in particular the central strip 9 of the sheet 2, is directly in contact with the portion 22. The packaging 26 has a shape cylindrical axis A and basic disk sector. This form is delimited by the central strip 9 of the sheet 2 closed at its ends by a bottom 27, formed by the rim 19 of the sheet 2 and the bottom panel 20, and by a cover 28, formed by the rim 23 of the sheet 2 and by the panel of cover 24.

Pour ouvrir l'emballage 26 et pouvoir accéder à la portion de fromage fondu 22, un consommateur peut, par exemple, saisir l'emballage 26 entre son pouce gauche et son index gauche qui prennent appui respectivement sur le couvercle 28 et sur le fond 27, le talon 16 étant alors dirigé vers la paume gauche du consommateur.To open package 26 and access the portion of processed cheese 22, a consumer can, for example, seize the package 26 between his left thumb and his left index finger respectively on the cover 28 and the bottom 27, the heel 16 being then directed to the consumer's left palm.

Le consommateur saisit alors très facilement entre son pouce droit et son index droit la languette de saisie 10 puis tire celle-ci vers la pointe 15 de l'emballage 26. Deux déchirures s'amorcent au niveau des coins 11 de la languette de saisie 10. Ces déchirures se propagent alors sensiblement le long des lignes de déchirure 8. Ainsi; le consommateur peut déchirer la bande centrale 9 sur les deux faces latérales de l'emballage 26. The consumer then grasps very easily between his thumb right and his right index finger 10 and pulls it to the tip 15 of the package 26. Two tears begin at the corners 11 of the tear tab 10. These tears then propagate substantially on the along the tear lines 8. So; the consumer can tear the tape central 9 on both side faces of the package 26.

Ensuite le consommateur n'a plus qu'à retirer le fond 27 et le couvercle 28, comme illustré par les flèches 30 sur la figure 8, et enfin le talon 16 pour pouvoir consommer la portion de fromage fondu 22.Then the consumer just has to remove the bottom 27 and the cover 28, as illustrated by the arrows 30 in FIG. 8, and finally the heel 16 to consume the portion of processed cheese 22.

L'ouverture de l'emballage 26 est donc relativement aisée.The opening of the package 26 is relatively easy.

De plus, on conçoit que l'élément 1, qui n'est constitué que d'une seule feuille 2, est relativement simple et économique à réaliser. En effet, cet élément 1 ne nécessite pas de rapporter sur la feuille 2 un organe de déchirement. Ainsi, tous les problèmes liés à cet organe de déchirement sont supprimés.Moreover, it is conceivable that the element 1, which consists only of a single sheet 2, is relatively simple and economical to achieve. Indeed, this Element 1 does not require reporting on Sheet 2 an organ of tear. So, all the problems related to this tearing organ are deleted.

Il n'est en particulier nécessaire ni d'utiliser plusieurs matériaux pour former l'élément 1 ni de prévoir des équipements spécifiques pour découper, poser et souder un organe de déchirement sur la feuille 2. De plus, les risques de défaut d'ouverture liés à un mauvais positionnement ou une mauvaise forme de l'organe de déchirement ainsi qu'à une rupture de cet organe sont supprimés.In particular, it is not necessary to use more than one material to form element 1 nor to provide specific equipment for cutting, laying and welding a tearing organ on the sheet 2. In addition, the risks of lack of opening due to incorrect positioning or bad shape of the tearing organ as well as a break in this organ are deleted.

L'invention peut bien sûr s'appliquer à des emballages d'autres formes que celles représentées. En particulier, les emballages peuvent être de forme cylindrique à base carrée, rectangulaire, circulaire ...The invention can of course apply to other packages forms than those represented. In particular, the packaging may be of cylindrical shape with square base, rectangular, circular ...

Selon une autre alternative, l'emballage 26 peut être constitué de deux éléments, un premier de ces éléments formant un godet et le deuxième élément formant un fond d'obturation de l'extrémité libre supérieure du godet. Le premier élément comprend alors une feuille dont la structure est adaptée pour assurer l'amorçage et la propagation de déchirures le long de lignes de déchirures prédéterminées.According to another alternative, the packaging 26 may consist of two elements, one of these elements forming a bucket and the second element forming a bottom closure of the upper free end of the bucket. The first element then comprises a sheet whose structure is adapted to ensure the priming and propagation of tears along lines of predetermined tears.

Ainsi, il est par exemple possible d'utiliser l'invention dans des emballages tels que ceux décrits dans les documents EP-242 268, EP-340 093 et FR-2 499 025.Thus, it is for example possible to use the invention in packaging such as those described in EP-242 268, EP-340 093 and FR-2 499 025.

Les matériaux constituant les feuilles des différents éléments d'un même emballage peuvent être différents.The materials constituting the leaves of the different elements the same packaging may be different.

La feuille 2 peut être réalisée par exemple en polyéthylène mono-orienté tel que celui commercialisé par la société Mobil sous la marque déposée « HICOR ».The sheet 2 may be made for example of polyethylene mono-oriented such as that marketed by Mobil under the brand filed "HICOR".

De manière plus générale, la feuille 2 est par exemple une feuille d'une matière plastique extrudée selon la direction longitudinale de la feuille 2. Les fibres ou chaínes de polymère de la feuille 2 sont donc orientées majoritairement le long de la direction d'extrusion, c'est à dire le long de la direction longitudinale de la feuille 2. More generally, the sheet 2 is for example a sheet an extruded plastic material in the longitudinal direction of the sheet 2. The fibers or polymer chains of the sheet 2 are therefore oriented mostly along the extrusion direction, ie along the longitudinal direction of the sheet 2.

De manière encore plus générale, la feuille peut comprendre plusieurs couches de matériaux dont l'un au moins est un matériau orienté principalement dans le sens longitudinal de la feuille 2.Even more generally, the sheet can include several layers of materials of which at least one is oriented material mainly in the longitudinal direction of sheet 2.

Ainsi, le polyéthylène mono-orienté « HICOR » peut être complexé à d'autres polymères, orientés ou non, comme du polypropylène orienté, du polyéthylène téréphtalate ou du polyamide.Thus, mono-oriented polyethylene "HICOR" can be complexed with other polymers, oriented or otherwise, such as polypropylene oriented, polyethylene terephthalate or polyamide.

Selon une autre variante, qui peut être combinée à celles décrites précédemment, les lignes 8 peuvent être des lignes de moindre résistance ménagées dans la feuille 2 par endommagement d'au moins une de ses surfaces. Cet endommagement peut être obtenu, par exemple, par marquage à l'aide d'un faisceau laser ou par marquage mécanique à l'aide d'un outil tel que, par exemple, une molette. Ici encore, la feuille 2 est donc conçue pour se déchirer d'elle-même le long d'au moins une partie des lignes de déchirure.According to another variant, which can be combined with those described above, lines 8 may be lines of lesser resistance in the sheet 2 by damage of at least one of its surfaces. This damage can be obtained, for example, by marking with a laser beam or mechanical marking using a tool such as, for example, a wheel. Here again, sheet 2 is designed to tear itself along at least a portion of the lines tearing.

Selon une autre variante non représentée, chaque entaille 6 peut être doublée d'une autre entaille 6 voisine et parallèle. Cette variante permet de réduire les risques de mauvaise ouverture de l'emballage 26, par exemple dans le cas où l'une des entailles 6 ne pourrait amorcer, du fait de sa position, une déchirure se propageant de manière satisfaisante dans l'emballage 26.According to another variant not shown, each notch 6 can to be doubled with another notch 6 neighbor and parallel. This variant allows to reduce the risks of poor opening of the package 26, for example in the event that one of the notches 6 could not start, because of its position, a tear propagating satisfactorily in the package 26.

Selon encore un autre mode de réalisation, la partie de la bande centrale 9 formant la languette de saisie 10 est recouverte d'un organe de renfort et de saisie de même forme rectangulaire qui va participer à l'amorçage des déchirures qui vont ensuite se propager le long des lignes 8. De manière plus générale, la languette de saisie pourra être formée au moins partiellement par un organe de renfort et de saisie rapporté au niveau de la zone d'amorçage des déchirures.According to yet another embodiment, the part of the band central 9 forming the gripping tongue 10 is covered with a body of reinforcement and seizure of the same rectangular shape that will participate in the initiation of the tears which will then spread along the lines 8. More generally, the input tab can be formed at least partially by a reinforcing and grabbing device reported at the level of the tear initiation zone.

Ce mode de réalisation est notamment intéressant dans le cas où la languette de saisie est située au voisinage de la pointe 15 de l'emballage 26.This embodiment is particularly interesting in the case where the catch tab is located near the tip 15 of packaging 26.

Dans ce cas, les contraintes de fabrication liées à la présence de cet organe de renfort et de saisie sont moins importantes que pour les organes de déchirement classiques. En effet, l'organe de renfort et de saisie assure ou participe à l'amorce des déchirures mais ne guide pas celles-ci sur toute la longueur des lignes de déchirure.In this case, the manufacturing constraints related to the presence of this reinforcing and seizing body is less important than for the classic tearing organs. Indeed, the reinforcing and seizing organ ensures or participates in the beginning of tears but does not guide them on the whole length of the tear lines.

Ce mode de réalisation peut également s'appliquer à la réalisation d'emballages tels que celui du document EP-340 093, comme illustré par la figure 9 qui correspond à la figure 1 du document EP-340 093, les lignes de déchirure 8 étant rectilignes. Dans ce cas, l'organe de renfort et de saisie 32 assure l'amorçage des déchirures et leur guidage dans les parties initiales 33 des lignes de déchirure 8. La feuille 2 assure ensuite elle-même le guidage des déchirures le long des parties terminales rectilignes 34 des lignes de déchirure 8, du fait de la conception de la feuille 2 qui comprend, par exemple, un matériau orienté principalement parallèlement à ces parties 34 des lignes 8.This embodiment can also be applied to the packaging such as that of EP-340 093, such as illustrated by Figure 9 which corresponds to Figure 1 of EP-340 093, the tear lines 8 being rectilinear. In this case, the reinforcing member and 32 ensures the initiation of tears and their guidance in the parts initials 33 tear lines 8. The sheet 2 then ensures itself the guiding the tears along the rectilinear end portions 34 of the lines tearing 8, because of the design of the sheet 2 which comprises, by for example, a material oriented mainly parallel to these parts lines 8.
