Description

Ensemble comprenant un emballage et une portion de fromage fondu. Set including a package and a portion of melted cheese.
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 a packaging tightly enveloping said portion, the packaging comprising an element itself comprising a sheet closely enveloping said portion and in contact with it, and priming means. of a tear so that the sheet tears along at least one tear line when a tab for gripping the element is pulled.
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). 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.Processed cheeses are understood to mean the products obtained by hot melting, in the presence or not of melting salts, cheeses alone or mixed with other dairy raw materials, butter, milk powder, whey, milk fat anhydrous, protein concentrates, etc.). The term processed cheese also includes products where the raw materials for cheese or milk are partially or completely replaced by vegetable matter (fat or protein). Generally, the portions of melted cheese, of pasty consistency, are closely packed in packages made from several elements which include aluminum foil.
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 an assembly of the aforementioned type, an element of the packaging usually comprises a sheet and a tearing member attached by welding to the sheet. One end of the tear member protrudes from the sheet to form the grip 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 tear member locally strengthens the sheet so that when a consumer pulls on the gripping tab, it allows a tear initiation of the sheet along the outer edges of the tear member. When the consumer continues to pull on the grip tab, the tearing member guides along its outer edges the tears in the sheet thus initiated. These tearing members are generally relatively long to be able to guide the tears over the entire 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. 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. Un but de l'invention est donc de fournir un ensemble du type précité qui soit plus simple et plus économique à réaliser.If the opening of such packages is generally satisfactory, their manufacture poses many problems including those related to the cutting, positioning and welding of the tearing members on the sheets of the packaging elements. In fact, the shape and positioning of the tearing members on the packaging elements must be relatively precise so that the opening of the packages formed is satisfactory. An object of the invention is therefore to provide an assembly of the aforementioned type which is simpler and more economical to produce.
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.To this end, the invention relates to an assembly of the aforementioned type, characterized in that at least a first part of said or each tear line is defined by or in a material of the sheet.
Selon des modes particuliers de réalisation, l'ensemble peut comprendre l'une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou selon toutes les combinaisons techniquement possibles :According to particular embodiments, the assembly may include one or more of the following characteristics, taken alone or in any technically possible combination:

- ledit matériau est un matériau orienté principalement selon la direction de la ou de chaque première partie de ligne de déchirure ;- Said material is a material oriented mainly along the direction of the or each first part of the tear line;
- une ligne de moindre résistance est ménagée dans la feuille sensiblement le long de la ou de chaque première partie de ligne de déchirure ;- A line of least resistance is formed in the sheet substantially along the or each first part of the tear line;
- la ou chaque ligne de moindre résistance est une ligne obtenue par endommagement de la feuille par un faisceau laser ;- The or each line of least resistance is a line obtained by damage to the sheet by a laser beam;
- la ou chaque ligne de moindre résistance est une ligne obtenue par endommagement mécanique de la feuille par un outil ;- The or each line of least resistance is a line obtained by mechanical damage to the sheet by a tool;
- la languette de saisie est formée au moins partiellement par une partie de la feuille ; - les moyens d'amorçage comprennent au moins une découpe ménagée dans la feuille à proximité de la languette de saisie et à une extrémité de la ou de chaque première partie de la ligne de déchirure ;- The grip tab is formed at least partially by a part of the sheet; - The priming means comprise at least one cut in the sheet near the gripping tab and at one end of the or each first part of the tear line;
- la feuille présente deux lignes de déchirure dont les premières parties sont sensiblement parallèles et espacées l'une de l'autre, les deux premières parties délimitant entre elles dans la feuille au moins une partie d'une bande déchirable terminée par la languette de saisie ;- The sheet has two tear lines, the first parts of which are substantially parallel and spaced from one another, the first two parts delimiting between them in the sheet at least part of a tearable strip terminated by the gripping tab ;
- l'emballage comprend un manchon sensiblement cylindrique, un fond et un couvercle qui ferment le manchon au niveau de ses extrémités inférieure et supérieure ; et - 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. 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 :- The packaging comprises a substantially cylindrical sleeve, a bottom and a cover which close the sleeve at its lower and upper ends; and - said packaging element forms at least said sleeve, said or each first part of tear line extending in the vicinity of the bottom or of the cover. The invention will be better understood on reading the description which follows, given solely by way of example, and made with reference to the appended drawings, in which:
- 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 ,- Figure 1 is a plan view of an element according to the invention, - Figures 2 to 6 are schematic perspective views illustrating successive steps of a method of packaging a portion of processed cheese from the element of 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,FIG. 7 is a schematic perspective view, partially broken away, illustrating the assembly comprising the portion of processed cheese and the packaging thus obtained,
- la figure 8 est une vue schématique en perspective, partiellement arrachée, illustrant l'ouverture de l'emballage de la figure 7,FIG. 8 is a schematic perspective view, partially broken away, illustrating the opening of the packaging of FIG. 7,
- la figure 9 est une vue analogue à la figure 1 illustrant un autre mode de réalisation de l'invention. La figure 1 représente un élément 1 pour former un emballage de conditionnement d'une portion de fromage fondu.- Figure 9 is a view similar to Figure 1 illustrating another embodiment of the invention. FIG. 1 represents an element 1 for forming a packaging for packaging 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 a rectangular sheet 2 elongated in a longitudinal direction. This sheet 2 is produced for example from a material oriented mainly longitudinally, that is to say 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 a resistance to tearing in its longitudinal direction less than its resistance to tearing in its transverse direction.
Par conséquent la feuille 2 présente la propriété de se déchirer, après amorce, préférentiellement de façon sensiblement rectiiigne le long de sa direction longitudinale.Consequently, the sheet 2 has the property of being torn, after initiation, preferably in a substantially straight line 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. 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.Longitudinal notches 6 of short length have been provided from the small left side 5 of the sheet 2. These notches 6 have for example a length of between 1 and 3 mm. The notches 6 are spaced transversely from one another and advantageously arranged symmetrically with respect to the median longitudinal axis of the sheet 2. The notches 6 are each arranged at a short distance. 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. 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 1 1 des entailles 6 délimitent les coins intérieurs de la languette de saisie 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.Due to the orientation of the material of the sheet 2, the longitudinal lines 8 (in dashed lines with two dashes in FIG. 1), which extend the notches 6 in the sheet 2, are predetermined tear lines of the item 2. These tear lines 8 delimit between them a central and longitudinal strip 9 which forms, between the notches 6, a gripping tab 10 of rectangular shape. The inner ends 1 1 of the notches 6 delimit the inner corners of the gripping tab 10. To form a packaging package for a portion of melted cheese, we come, as illustrated by the arrow 12 in FIG. 2, to wrap the element 1 around a mandrel 13 of cylindrical shape with axis A and based on disc sector.
Ainsi, on obtient un manchon 14 de forme correspondante, visible sur les figures 3 et 4. Ce manchon 14 présente une pointe 1 5 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, one obtains a sleeve 14 of corresponding shape, visible in Figures 3 and 4. This sleeve 14 has a tip 1 5 and a curved heel 16. The element 1 overlaps itself in the vicinity of the heel 16 on a low part of the length of a lateral face 17 of the sleeve 14, this face 17 connecting the toe 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 edge 18 connecting the heel 16 to the lateral face 17. Thus, the gripping tongue 10 projects relative to the sleeve 14, beyond the edge 18, in the extension of the lateral 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 removed axially from the sleeve 14 so that the flange 19 of the sleeve 14, delimited by the long side 3 of the sheet 2 and the adjacent tear line 8, protrudes from 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, the flange 19 of the sleeve 14 is then folded back over the mandrel 13 by folding substantially along the adjacent tear line 8.
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.A bottom panel 20 is then sealed, in the shape of a disk sector corresponding to that of the mandrel 13, against the flange 19 folded down from the sleeve 14. This panel 20 is for example made of the same material as the 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.A cup 21 is thus obtained, shown in FIG. 5 after turning over with respect to FIG. 4, and after complete axial withdrawal 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 . 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. On vient ensuite introduire un panneau de couvercle 24 de forme en secteur de disque correspondant à celle du mandrin 1 3 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.The cup 21 is then partially filled with melted cheese 22 leaving the upper rim 23 of the sleeve 14, delimited by the long side 4 of the sheet 2 and the adjacent tear line 8, protruding from the upper surface of the cheese 22 contained in the bucket 21. This melted cheese 22 then forms a portion, of cylindrical shape with axis A and basic in the sector of the disc, and contained in the cup 21. We then introduce a cover panel 24 in the shape of a disk sector corresponding to that of the mandrel 1 3 in the free upper end of the sleeve 14. This panel 24 is for example made of the same material as the sheet 2. The panel the cover 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 . 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. 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. 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 1 5 de l'emballage 26. Deux déchirures s'amorcent au niveau des coins 1 1 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. 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.As illustrated in FIG. 6, the upper rim 23 of the sleeve 14 is then folded back over the cover panel 24 by folding the sheet 2 substantially along the adjacent tear line 8. This rim 23 is then sealed on the cover panel 24. In a variant not shown, the sealing of the cover panel 24 on the sleeve 14 is carried out by sealing a rim of the panel 24, folded outwards, on the rim 23 , for example using sealing jaws which can move radially with respect to the axis A. The bottom panel 20 can also be similarly sealed on the sleeve 14 to form the cup 21. As illustrated in FIG. 7, an assembly 25 is thus obtained comprising a packaging 26 and a portion of melted cheese 22 tightly wrapped by the packaging 26 and visible thanks to the cutaway of FIG. 7. The packaging 26, and in in particular the central strip 9 of the sheet 2 is directly in contact with the portion 22. The package 26 has a cylindrical shape with axis A and base in the disc sector. This shape 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 by the bottom panel 20, and by a cover 28, formed by the rim 23 of the sheet 2 and through the cover panel 24. To open the packaging 26 and be able to access the portion of processed cheese 22, a consumer can, for example, grasp the packaging 26 between his left thumb and his left index finger which bear respectively on the cover 28 and on the bottom 27, the heel 16 then being directed towards the consumer's left palm. The consumer then very easily grasps the grip tab 10 between his right thumb and his right index finger and then pulls it towards the tip 1 5 of the package 26. Two tears start at the corners 1 1 of the grip tab. seizure 10. These tears then propagate substantially along the tear lines 8. Thus, the consumer can tear the central strip 9 on the two lateral faces of the packaging 26. Then the consumer only 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 be able to consume the portion of processed cheese 22.
L'ouverture de l'emballage 26 est donc relativement aisée. 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. II 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.The opening of the package 26 is therefore relatively easy. In addition, it is understood that the element 1, which consists of only one sheet 2, is relatively simple and economical to produce. Indeed, this element 1 does not require to bring on the sheet 2 a tearing member. Thus, all the problems associated with this tearing member are eliminated. It is in particular neither necessary to use several materials to form the element 1 nor to provide specific equipment for cutting, placing and welding a tearing member on the sheet 2. In addition, the risks of failure to open linked to a bad positioning or a bad shape of the tearing organ as well as to a rupture of this organ are eliminated.
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 be applied to packaging of other shapes than those shown. In particular, the packages can 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. 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.According to another alternative, the packaging 26 may consist of two elements, a first of these elements forming a cup and the second element forming a closure bottom of the upper free end of the cup. The first element then comprises a sheet whose structure is adapted to ensure the initiation and the propagation of tears along predetermined tear lines. Thus, it is for example possible to use the invention in packages such as those described in documents 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. 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 materials constituting the sheets of the different elements of the same package can be different. The sheet 2 can be produced for example from mono-oriented polyethylene such as that sold by the company Mobil under the registered trademark "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 chaînes 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. 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.More generally, the sheet 2 is for example a sheet of a plastic material extruded in the longitudinal direction of the sheet 2. The fibers or polymer chains of the sheet 2 are therefore oriented mainly along the direction of extrusion , i.e. along the longitudinal direction of sheet 2. Even more generally, the sheet may comprise several layers of material, at least one of which is a material oriented mainly in the longitudinal direction of the sheet 2.
Ainsi, le polyéthylène mono-orienté « HICOR » peut être complexé à d'autres polymères, orientés ou non, comme du polypropylene orienté, du polyéthylène téréphtalate ou du polyamide.Thus, mono-oriented polyethylene "HICOR" can be complexed with other polymers, oriented or not, such as oriented polypropylene, 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. 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. 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 another variant, which can be combined with those described above, the lines 8 can be lines of lesser resistance formed in the sheet 2 by damage to at least one of its surfaces. This damage can be obtained, for example, by marking with a laser beam or by mechanical marking with a tool such as, for example, a thumb wheel. Here again, the sheet 2 is therefore designed to tear itself along at least part of the tear lines. According to another variant not shown, each notch 6 can be doubled with another neighboring and parallel notch 6. This variant makes it possible to reduce the risks of poor opening of the packaging 26, for example in the case where one of the notches 6 cannot initiate, due to its position, a tear propagating satisfactorily in the packaging 26 According to yet another embodiment, the part of the central strip 9 forming the gripping tab 10 is covered with a reinforcing and gripping member of the same rectangular shape which will participate in the initiation of the tears which will then propagate along the lines 8. More generally, the gripping tongue can be formed at least partially by a reinforcing and gripping member attached to the level of the initiation zone for tears.
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. 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. 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 is particularly advantageous in the case where the gripping tab is located in the vicinity of the tip 15 of the package 26. In this case, the manufacturing constraints linked to the presence of this reinforcing and gripping member are less important than for conventional tearing devices. Indeed, the reinforcing and gripping member ensures or participates in the initiation of the tears but does not guide them over the entire length of the tear lines. This embodiment can also be applied to the production of packaging such as that of document EP-340 093, as illustrated by FIG. 9 which corresponds to FIG. 1 of document EP-340 093, the tear lines 8 being rectilinear. In this case, the reinforcing and gripping member 32 ensures the initiation of the tears and their guidance in the initial parts 33 of the tear lines 8. The sheet 2 then itself guides the tears along the terminal parts straight lines 34 of tear lines 8, due to the design of sheet 2 which comprises, for example, a material oriented mainly parallel to these parts 34 of lines 8.
