Abstract

The package (1) of a foodstuff (2), wrapped in at least one plastics film (3), has a rupture resistance at least equal to that of the film wrapping. To split the package open, the film and/or the foodstuff both break apart (4) in a preferred direction, through the film orientation, when the user snaps it open with both hands. When split apart, the separate portions are held within the film wrapping and the sealed ends (9).

Description

La présente invention a pour objet un produit emballé comprenant d'une part un produit alimentaire susceptible d'être fractionné en le cassant et d'autre part un emballage présentant au moins un film en matière plastique.The present invention relates to a packaged product comprising firstly a food product capable of being fractionated by breaking it and secondly a package having at least one plastic film.

On connaît de la demande PCT WO 99/58421 (MARS ALIMENTAIRE) un produit emballé du type précité dans lequel le film plastique doit être découpé périmétriquement selon une ou plusieurs lignes de découpe avant que le produit puisse être fractionné par cassage.It is known from PCT application WO 99/58421 (FOOD MARKS) a packaged product of the aforementioned type wherein the plastic film is to be cut perimetrically along one or more cutting lines before the product can be fractionated by breaking.

Dans la demande PCT WO 00/59801 (DOVEUROPE), l'emballage plastique contient deux produits espacés longitudinalement l'un de l'autre et l'accès à ces produits s'effectue en brisant le film le long d'une ligne de pré-découpe.In PCT application WO 00/59801 (DOVEUROPE), the plastic package contains two products spaced longitudinally from each other and access to these products is effected by breaking the film along a meadow line. -cutout.

Enfin, on connaît de la demande de brevet allemand DE-2 458 462 (Alfred RITTER) une tablette de chocolat sécable selon des carrés de chocolat, et qui comporte une soudure longitudinale située à l'aplomb d'une ligne de séparation entre les carrés de chocolat. De la sorte, un consommateur peut, selon cette ligne, qui est la ligne de soudure longitudinale de l'emballage selon la technique dite "flow-pack", réaliser une rupture de la plaque de chocolat qui entraîne également une ouverture partielle de l'emballage par séparation par traction au niveau de la soudure longitudinale « chair contre chair », ce qui permet d'accéder à une rangée de carrés de chocolat, et de refermer ensuite l'emballage.Finally, German patent application DE-2,458,462 (Alfred RITTER) discloses a chocolate bar which can be scored according to chocolate squares, and which comprises a longitudinal weld located directly above a line of separation between the squares. of chocolate. In this way, a consumer can, according to this line, which is the longitudinal weld line of the package according to the so-called "flow-pack" technique, achieve a break of the chocolate plate which also causes a partial opening of the Tensile separation wrapping at the longitudinal "flesh-to-flesh" weld, providing access to a row of chocolate squares, and then closing the package.

La présente invention propose pour but un produit emballé dans lequel on obtient en un seul geste à la fois la séparation du produit alimentaire et de son film d'emballage.The present invention provides a packaged product in which is obtained in one step at a time the separation of the food product and its packaging film.

L'invention concerne ainsi un produit alimentaire emballé comprenant d'une part un produit alimentaire susceptible d'être fractionné en le cassant et d'autre part un emballage présentant au moins un film plastique, caractérisé en ce que le produit alimentaire présente une résistance à la rupture qui est au moins égale à celle du film, et en ce que le film et/ou le produit présente une propriété de rupture préférentielle permettant une rupture périmétrique selon une direction préférentielle sur le pourtour du produit emballé, de sorte que, lorsqu'un consommateur saisit le produit emballé à deux mains pour le fractionner, la rupture du produit alimentaire entraîne également celle de l'emballage.The invention thus relates to a packaged food product comprising, on the one hand, a food product capable of being fractionated by breaking it and, on the other hand, a package having at least one plastic film, characterized in that the food product has a resistance to the break that is at least equal to that of the film, and that the film and / or the product has a preferential breaking property allowing a perimeter break in a preferential direction around the periphery of the packaged product, so that when a consumer grasps the two-handed packaged product to split it, the breakage of the food product also results in packaging.

Cette propriété de rupture préférentielle s'exerce avantageusement pour le film et/ou pour le produit dans une zone préférentielle, notamment selon au moins une ligne préférentielle.This preferential rupture property is advantageously exerted for the film and / or for the product in a preferential zone, in particular according to at least one preferred line.

Le produit alimentaire peut présenter une région de faiblesse telle qu'une pré-découpe, ou une région de rétrécissement de section produisant un affaiblissement entre 10 et 40 % avantageusement entre 10 et 30 % et par exemple de 25 % de l'effort de rupture du produit.The food product may have a region of weakness such as a pre-cut, or a section-shrinking region producing a weakening between 10 and 40%, advantageously between 10 and 30% and for example 25% of the breaking force. of the product.

Selon une variante correspondant à la technique dite "flow-pack", le film est refermé sur lui-même autour du produit le long d'une ligne de soudure s'étendant entre deux bords opposés du produit dans une première direction, et la direction de rupture préférentielle est une deuxième direction inclinée par rapport à la première direction et préférentiellement perpendiculaire à celle-ci.According to a variant corresponding to the technique called "flow-pack", the film is closed on itself around the product along a weld line extending between two opposite edges of the product in a first direction, and the direction preferential rupture is a second direction inclined relative to the first direction and preferably perpendicular thereto.

Le produit est avantageusement de forme allongée et ladite direction préférentielle est une direction transversale du produit.The product is advantageously elongated and said preferred direction is a transverse direction of the product.

Selon une première variante, le produit comporte au moins un film mono-orienté présentant une déchirabilité préférentielle suivant ladite direction préférentielle.According to a first variant, the product comprises at least one mono-oriented film having a preferable tearability in said preferred direction.

Selon un premier mode de réalisation, il comporte deux films mono-orientés de même orientation superposés. Une impression de marquage d'au moins une zone de déchirure peut être réalisée en sandwich entre les deux films mono-orientés. Cette impression de marquage a pour fonction première de permettre d'éviter un effilochement des bords des films lors de l'ouverture du produit.According to a first embodiment, it comprises two mono-oriented films of the same superimposed orientation. A marking impression of at least one tear zone can be made sandwiched between the two mono-oriented films. This marking printing has the primary function of preventing a fray of the edges of the films during the opening of the product.

Avantageusement, au moins un des deux films est au moins localement transparent de manière que ladite impression de marquage soit visible.Advantageously, at least one of the two films is at least locally transparent so that said marking impression is visible.

Selon une deuxième variante, un produit présente un dit film mono-orienté superposé à un film bi-orienté présentant une zone de déchirure préférentielle, notamment une ligne de déchirure préférentielle.According to a second variant, a product has a said mono-oriented film superimposed on a bi-oriented film having a preferential tearing zone, in particular a preferential tear line.

Le produit peut présenter au moins un film polymère présentant une zone d'affaiblissement microporeuse, telle que décrit par exemple dans le brevet français n° 2 717 449 (CMB FLEXIBLE).The product may have at least one polymeric film having a microporous weakening zone, as described, for example, in French Patent No. 2,717,449 (CMB FLEXIBLE).

Ce film polymère peut être par exemple laminé avec un film bi-orienté. Selon une autre variante, le produit comporte au moins un film bi-orienté présentant une zone de rupture préférentielle, notamment une ligne de rupture. Le produit peut en particulier comporter deux films bi-orientés laminés entre eux dont au moins un présente une dite zone de rupture préférentielle, notamment une ligne de rupture. Selon une variante préférée, les deux films bi-orientés présentent chacun une dite zone de rupture préférentielle, ces deux zones étant parallèles et décalées l'une par rapport à l'autre, de sorte que, lors de la rupture, la zone de rupture préférentielle d'un desdits films bi-orientés se déchire et que cette déchirure se propage entre les deux films, en particulier à travers la couche de colle de laminage, pour rejoindre la zone de rupture préférentielle de l'autre film bi-orienté.This polymer film may for example be laminated with a bi-oriented film. According to another variant, the product comprises at least one bi-oriented film having a preferential rupture zone, in particular a rupture line. The product may in particular comprise two bi-oriented films laminated between them, at least one of which has a said preferential rupture zone, in particular a rupture line. According to a preferred variant, the two bi-oriented films each have a said preferential rupture zone, these two zones being parallel and offset with respect to each other, so that, at the time of rupture, the rupture zone Preferably, one of said bi-oriented films is torn and this tear propagates between the two films, in particular through the layer of rolling glue, to join the preferential rupture zone of the other bi-oriented film.

Selon encore une autre variante, la propriété de rupture préférentielle périmétrique est obtenue grâce à une zone de scellage à plat « cuir contre chair » s'étendant sur tout le pourtour du produit, auquel cas la rupture de l'emballage s'effectue sous l'action de forces de cisaillement qui produisent un délaminage relatif des deux parties du film qui viennent en recouvrement périmétrique. Le film peut être ou non monocouche. Dans la technique "flow-pack", il s'agit d'une ligne de soudure périmétrique inclinée et de préférence perpendiculaire à la ligne de soudure longitudinale du produit.According to yet another variant, the perimeter preferential rupture property is obtained by means of a "leather against flesh" flat sealing zone extending around the entire periphery of the product, in which case the rupture of the packaging takes place under the action of shear forces which produce a relative delamination of the two parts of the film which come in perimeter recovery. The film may or may not be monolayered. In the "flow-pack" technique, it is a perimetrical welding line inclined and preferably perpendicular to the longitudinal weld line of the product.

Un film mono-orienté ou un film polymère présentant une zone d'affaiblissement périmétrique microporeuse peut être remplacée, dans un laminat, par un papier (par exemple de grammage 35 - 60 g/m2) revêtu de polyéthylène.A single-oriented film or a polymer film having a microporous perimetric weakening zone can be replaced in a laminate by a paper (for example of grammage 35 - 60 g / m 2 ) coated with polyethylene.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux à la lecture de la description qui va suivre, donné à titre d'exemples non limitatifs, en liaison avec les dessins annexés dans lesquels :

  • la figure 1a représente un produit selon l'invention avant rupture,
  • la figure 1b représente ce même produit après rupture par un consommateur,
  • les figures 1c et 1d représentent deux variantes de formes du produit alimentaire, respectivement en vue latérale et en vue de dessus,
  • les figures 2 à 8 illustrent différentes variantes de l'invention.
Other features and advantages of the invention will appear better on reading the following description, given by way of non-limiting examples, in conjunction with the appended drawings in which:
  • FIG. 1a represents a product according to the invention before rupture,
  • FIG. 1b represents this same product after rupture by a consumer,
  • FIGS. 1c and 1d show two variant shapes of the food product, respectively in lateral view and in plan view,
  • Figures 2 to 8 illustrate different variants of the invention.

Selon la figure 1a, un produit alimentaire emballé désigné par le repère général 1 comporte un produit alimentaire 2 fractionnable par cassage, par exemple un biscuit, une barre de confiserie ou une barre chocolatée, etc. qui présente donc des caractéristiques de dureté et de craquant appropriés ainsi qu'une géométrie (forme carrée, rectangle, ovale ou ronde, etc...) permettant une prise en main aisée, et un film d'emballage 3 mono ou multicouches réalisé par une technique connue, par exemple la technique dite "flow-pack". Le produit alimentaire 2 peut être également constitué par un empilement d'au moins deux produits élémentaires.According to FIG. 1a, a packaged food product designated by general reference 1 comprises a breakable food product 2, for example a biscuit, a candy bar or a chocolate bar, etc. which therefore has appropriate hardness and crunch characteristics and a geometry (square, rectangle, oval or round shape, etc.) allowing easy handling, and a mono or multilayer packaging film 3 made by a known technique, for example the so-called "flow-pack" technique. The food product 2 may also consist of a stack of at least two elementary products.

Le produit 2 peut être en particulier un biscuit CHOCO PRINCE ou PRINCE FOURRE de LU, ou bien encore un biscuit commercialisé en Belgique sous la marque CHACHA. Ces produits présentent une force de rupture de l'ordre de 25 N jusqu'à environ 50N.The product 2 may be in particular a CHOCO PRINCE or PRINCE FOURRE biscuit LU, or even a biscuit marketed in Belgium under the trademark CHACHA. These products have a breaking force of the order of 25 N up to about 50N.

Si on veut imposer une région précise pour découper le produit, par exemple pour obtenir deux portions égales, il est possible de ménager dans le produit une zone de rupture préférentielle, par exemple une rainure 7 formant une pré-découpe, et/ou de conférer au produit 2 une forme présentant une région rétrécie dans la partie centrale (voir les figures 1c et 1 d).If it is desired to impose a specific region for cutting the product, for example to obtain two equal portions, it is possible to provide in the product a preferential breaking zone, for example a groove 7 forming a pre-cut, and / or to confer to product 2 a shape having a narrowed region in the central portion (see Figures 1c and 1d).

Cette rainure 7 et/ou cette région rétrécie 8 sont choisies de manière à induire localement une diminution de la résistance à la rupture comprise entre 10 % et 40 %, et notamment entre 10 % et 35 % et plus particulièrement inférieure à 25 %, entre la région centrale 4 et le reste du produit.This groove 7 and / or this narrowed region 8 are chosen so as to locally induce a decrease in the breaking strength. between 10% and 40%, and especially between 10% and 35% and more particularly less than 25%, between the central region 4 and the rest of the product.

Avantageusement, les zones de rupture préférentielle sont telles que l'effet barrière (humidité et/ou oxygène) reste suffisant pour que le produit 2 conserve ses caractéristiques et en particulier une force de rupture suffisante pendant toute la période de conservation en rayon à température ambiante.Advantageously, the preferential zones of rupture are such that the barrier effect (moisture and / or oxygen) remains sufficient for the product 2 to retain its characteristics and in particular a sufficient breaking force throughout the shelf life at room temperature. .

On voit à la figure 1a, que le consommateur peut positionner ses mains de part et d'autre d'une région centrale 4 du produit en pinçant le film entre ses doigts et les bords supérieur 5 et inférieur 6 du produit 2 pour éviter un glissement entre le film 3 et le produit 2. En exerçant un mouvement sec tel qu'il est usuel lorsque l'on casse un biscuit ou une barre chocolatée, le consommateur fractionne le produit (biscuit, chocolat, etc.) en deux morceaux dans son emballage en entraînant une déchirure du film sur pratiquement tout son périmètre au niveau de la région centrale dans laquelle le produit se casse (figure 1b). Ce phénomène est dû au fait que le film et/ou le produit présente une propriété de rupture préférentielle permettant une rupture périmétrique selon une direction préférentielle.It can be seen in FIG. 1a that the consumer can position his hands on either side of a central region 4 of the product by pinching the film between his fingers and the upper and lower edges 5 of the product 2 to prevent slippage. between the film 3 and the product 2. By exerting a dry movement as is usual when breaking a biscuit or a chocolate bar, the consumer splits the product (biscuit, chocolate, etc.) into two pieces in his packaging by causing tearing of the film over substantially its entire perimeter at the central region in which the product breaks (Figure 1b). This phenomenon is due to the fact that the film and / or the product has a preferential fracture property allowing a perimetric rupture in a preferred direction.

Selon une première variante illustrée par la figure 2, le film 3 est un film mono-orienté 31 dans une direction préférentielle qui est la direction transversale du produit de sorte que le film 3 présente une direction de rupture préférentielle perpendiculaire à sa direction longitudinale (par exemple la direction longitudinale de défilement du produit dans la technique "flow-pack"). Ce film mono-orienté peut être un film en polyéthylène d'épaisseur comprise par exemple entre 20 et 50 µ et préférentiellement égale à 30 µ. De tels films sont fabriqués notamment par EXXON MOBIL CHEMICAL.According to a first variant illustrated in FIG. 2, the film 3 is a mono-oriented film 31 in a preferential direction which is the transverse direction of the product so that the film 3 has a preferential direction of rupture perpendicular to its longitudinal direction (by example the longitudinal direction of scrolling of the product in the "flow-pack" technique). This mono-oriented film may be a polyethylene film of thickness for example between 20 and 50 microns and preferably equal to 30 microns. Such films are manufactured in particular by EXXON MOBIL CHEMICAL.

Pour que cette rupture puisse être réalisée, il faut que la résistance à la rupture du produit 2 par exemple un biscuit ou une barre chocolatée, soit supérieure ou égale à !a résistance à la rupture du film 3 dans la direction préférentielle. Dans le cas illustré ci-dessus, le consommateur prend le produit de part et d'autre d'une région centrale, et la rupture s'opère spontanément pratiquement dans la même région pour le film et pour le produit, étant entendu que la rupture du produit entraîne celle du film dans la même zone.In order for this break to be possible, the breaking strength of the product 2, for example a biscuit or a chocolate bar, must be greater than or equal to the breaking strength of the film 3 in the preferred direction. In the case illustrated above, the consumer takes the product on either side of a central region, and the rupture takes place spontaneously practically in the same region for the film and for the product, it being understood that the rupture of the product causes that of the film in the same zoned.

En effet, le produit tend à se briser dans la région où les contraintes sont les plus fortes. Il en va de même pour le film qui s'étire le plus dans la région où le produit se rompt.Indeed, the product tends to break in the region where the constraints are the strongest. The same goes for the film that stretches the most in the region where the product breaks.

Du fait que les films mono-orientés présentent des propriétés de déchirabilité caractéristiques dans une direction, ici la direction transversale du produit, ils permettent d'obtenir une force d'amorce à la déchirure relativement faible et une orientation de cette déchirure qui est maîtrisée parallèlement à l'orientation. Ainsi, la mise en oeuvre d'un tel film permet d'obtenir le résultat escompté pour un biscuit ou une barre chocolatée présentant ou non une zone de faiblesse. On dispose d'une latitude, par exemple en jouant sur l'épaisseur du film pour adapter la force nécessaire au déchirement du film pour qu'elle soit du même ordre de grandeur ou inférieure à celle nécessaire au fractionnement du produit.Since the mono-oriented films have characteristic tear-off properties in one direction, here the transverse direction of the product, they make it possible to obtain a relatively low tear initiation force and an orientation of this tear which is controlled in parallel. to orientation. Thus, the implementation of such a film makes it possible to obtain the desired result for a biscuit or a chocolate bar with or without a zone of weakness. There is latitude, for example by adjusting the thickness of the film to adapt the force required to tear the film so that it is of the same order of magnitude or less than that required for product splitting.

On obtient ainsi de manière reproductible une double action d'ouverture et de fractionnement du produit en un seul geste.This gives a reproducible double action of opening and splitting the product in a single gesture.

Dans le mode de réalisation représenté à la figure 3, l'emballage externe, par exemple réalisé selon la technique "flow-pack", comporte deux films mono-orientés superposés, et notamment laminés, représentés par les repères 31 et 32, le laminage étant réalisé grâce à une couche 33 de colle de lamination. L'un ou l'autre des films peut comporter, dans la zone où il est prévu de déchirer le film, une zone d'impression 34 s'étendant sur le périmètre de l'emballage (par exemple le périmètre 82 de la figure 8). Avantageusement, l'un des deux films, par exemple le film 31, est transparent, ce qui permet au consommateur de visualiser la zone de marquage à l'encre.In the embodiment shown in FIG. 3, the outer packaging, for example made according to the "flow-pack" technique, comprises two superimposed mono-oriented films, and in particular rolled films, represented by the marks 31 and 32, rolling being made thanks to a layer 33 of lamination glue. One or the other of the films may comprise, in the zone where it is intended to tear the film, a printing zone 34 extending on the perimeter of the package (for example the perimeter 82 of FIG. ). Advantageously, one of the two films, for example the film 31, is transparent, which allows the consumer to view the ink marking area.

La mise en oeuvre de deux films mono-orientés superposés d'épaisseur par exemple comprise entre 20 µ et 50 µ permet d'augmenter la barrière intrinsèque de l'emballage dans le cas de produits plus exigeants, notamment du point de vue barrière contre l'humidité. En outre, ce mode de réalisation permet d'augmenter la rigidité de l'emballage, ce qui présente des avantages d'une part au niveau de la machinabilité du film laminé et d'autre part de l'impact du produit sur le consommateur lors de sa prise en main.The use of two superimposed mono-oriented films of thickness, for example between 20 μ and 50 μ, makes it possible to increase the intrinsic barrier of the packaging in the case of more demanding products. especially from the point of view barrier against moisture. In addition, this embodiment makes it possible to increase the rigidity of the package, which has advantages on the one hand in the machinability of the rolled film and, on the other hand, in the impact of the product on the consumer during of his grip.

La mise en place d'une encre appropriée, par exemple une encre dure, au niveau de la zone de déchirure du film, permet d'éviter la présence de filaments sur les bords du film déchiré. En effet, l'encre modifie les propriétés intrinsèques du film du point de vue de la rupture. Avantageusement, la zone encrée 34 est rendue visible.The introduction of a suitable ink, for example a hard ink, at the tearing zone of the film, makes it possible to avoid the presence of filaments on the edges of the torn film. Indeed, the ink modifies the intrinsic properties of the film from the point of view of the rupture. Advantageously, the inked area 34 is made visible.

Dans le mode de réalisation de la figure 4, on met en oeuvre un film bi-orienté 41 par exemple d'épaisseur comprise entre 20 et 50 µ, laminé avec un film mono-orienté 42 par exemple en polyoléfine. Le film bi-orienté 41 présente une zone de faiblesse 43 au niveau de la zone de déchirure recherchée (par exemple le périmètre 82 de la figure 8). La zone de faiblesse 43 peut être une découpe sur tout ou partie de l'épaisseur du film, un matriçage ou bien encore un marquage en pointillés sur tout ou partie de l'épaisseur du film. Le film bi-orienté 41 peut être par exemple un film polyester d'épaisseur comprise entre 8 et 25 µ et préférentiellement égale à 12 µ. Le film mono-orienté 42 peut être le même qu'à la figure 1.In the embodiment of FIG. 4, a bi-oriented film 41, for example of thickness between 20 and 50 μ, is used, laminated with a mono-oriented film 42, for example made of polyolefin. The bi-oriented film 41 has a zone of weakness 43 at the desired tearing zone (for example the perimeter 82 of FIG. 8). The weak zone 43 may be a cutout on all or part of the thickness of the film, a stamping or even a dashed marking on all or part of the thickness of the film. The bi-oriented film 41 can be for example a polyester film with a thickness of between 8 and 25 μ and preferably equal to 12 μ. The mono-oriented film 42 may be the same as in FIG.

La combinaison des deux films 41 et 42 permet d'améliorer la déchirabilité tout en évitant la présence de filaments sur les bords de la déchirure. En outre, ceci entraîne une augmentation de la barrière intrinsèque de l'emballage, notamment vis-à-vis de l'humidité, ainsi que de la rigidité. En outre, le fait d'associer un film mono-orienté et un film bi-orienté permet d'obtenir une structure beaucoup moins sensible aux arrêts machine dans le cadre de la technique dite "flow-pack", notamment en ce qui concerne la réalisation de la soudure longitudinale (couple température et temps de contact avec les mâchoires de scellage).The combination of the two films 41 and 42 improves the tearability while avoiding the presence of filaments on the edges of the tear. In addition, this causes an increase in the intrinsic barrier of the package, especially with respect to moisture, as well as rigidity. In addition, the fact of associating a mono-oriented film and a bi-oriented film makes it possible to obtain a structure that is much less sensitive to machine stops in the context of the so-called "flow-pack" technique, particularly as regards the realization of the longitudinal weld (temperature torque and contact time with the sealing jaws).

En variante, le film 42 mono-orienté peut être remplacé par un film polymère, notamment en polypropylène, présentant une zone de faiblesse 43 microporeuse, tel que décrit dans le brevet français FR 2 717 449 précité, ou bien encore un papier de 35 à 60 g/m2 revêtu d'une couche par exemple de polyéthylène.Alternatively, the mono-oriented film 42 may be replaced by a polymer film, especially polypropylene, having a microporous zone of weakness 43, as described in the French patent FR 2,717,449, or else a paper of 35 to 60 g / m 2 coated with a layer for example of polyethylene.

Dans le mode de réalisation des figures 5a et 5b, l'emballage externe comprend deux films bi-orientés 51 et 52 laminés (par exemple de type polyoléfine) dont l'un au moins présente une zone de faiblesse 53 et/ou 54, au niveau de la zone de déchirure de produit (par exemple selon le périmètre 82 de la figure 8). Comme dans le cas précédent, cette zone de faiblesse 53 et/ou 54 ménagée sur l'un et/ou l'autre film 51 et/ou 52, peut être réalisée par une découpe sur toute ou partie de l'épaisseur du film par un matriçage ou par une découpe en pointillés sur toute ou partie de l'épaisseur du film. Il est également possible de mettre en oeuvre un film 51 et/ou un film 52 présentant une zone de faiblesse microporeuse 53 et/ou 54 selon le Brevet français 2 717 449. A la figure 5a, les zones 53 et 54 sont des rainures, la rainure 53 traversant complètement le film 51. A la figure 5b, la zone 53 est une rainure, et la zone 54 est une zone de faiblesse d'un autre type.In the embodiment of FIGS. 5a and 5b, the outer packaging comprises two laminated films 51 and 52 that are laminated (for example of the polyolefin type), at least one of which has a zone of weakness 53 and / or 54, the level of the product tear zone (for example according to the perimeter 82 of FIG. 8). As in the previous case, this zone of weakness 53 and / or 54 formed on one and / or the other film 51 and / or 52, can be achieved by cutting all or part of the thickness of the film by a stamping or dotted cut on all or part of the thickness of the film. It is also possible to implement a film 51 and / or a film 52 having a zone of microporous weakness 53 and / or 54 according to French Patent 2,717,449. In FIG. 5a, the zones 53 and 54 are grooves, the groove 53 completely through the film 51. In Figure 5b, the zone 53 is a groove, and the zone 54 is a zone of weakness of another type.

Une mise en oeuvre préférée est illustrée à aux figures 5c et 5d. Les zones de faiblesse périmétriques 53 et 54 (découpe, matriçage, microporosité) ne sont pas au même niveau mais sont parallèles et décalées l'une par rapport à l'autre, par exemple longitudinalement si on considère notamment le cas d'un emballage de type « flow-pack ».A preferred implementation is illustrated in Figures 5c and 5d. The zones of weakness perimeter 53 and 54 (cutting, stamping, microporosity) are not at the same level but are parallel and offset with respect to each other, for example longitudinally if we consider in particular the case of a packaging of flow-pack type.

Avec un tel décalage, typiquement compris entre un millimètre et un centimètre, la déchirure du complexe qui s'opère lors de l'ouverture de l'emballage s'effectue au niveau de la zone de faiblesse d'un des deux films, puis se propage au niveau de la zone de collage 55, c'est-à-dire en délaminant localement les deux films 51 et 52, pour rejoindre la zone de faiblesse du deuxième film suivant un phénomène de délaminage, et ce sur le périmètre de l'emballage pour obtenir une séparation des deux produits et de l'emballage.With such an offset, typically between one millimeter and one centimeter, the tearing of the complex which occurs during the opening of the package takes place at the level of the weak zone of one of the two films, then propagation at the level of the bonding zone 55, that is to say locally delaminating the two films 51 and 52, to join the weak zone of the second film following a delamination phenomenon, and this on the perimeter of the packaging to obtain a separation of the two products and the packaging.

Le mode de réalisation représenté à la figure 6 met en oeuvre un film bi-orienté type polyoléfine qui présente une zone de faiblesse périmétrique 66 au niveau de la zone de déchirure de l'emballage (par exemple selon le contour 82 de la figure 8). Cette zone de faiblesse est ménagée sur une bande de film plastique ou sur une bande de papier, revêtu de polyéthylène 63 qui est scellée par soudure ou collage à plat 64 et 65 sur les bords 61 et 62 du film constituant l'emballage. Ce mode de réalisation est également susceptible d'être mis en oeuvre dans le cas où le film bi-orienté est superposé avec un autre film, mono-orienté ou bi-orienté.The embodiment shown in FIG. 6 implements a bi-oriented polyolefin type film which has a zone of perimetric weakness 66 at the level of the tear zone of the package (for example). example according to the contour 82 of Figure 8). This zone of weakness is formed on a strip of plastic film or on a strip of paper, coated with polyethylene 63 which is sealed by welding or flat gluing 64 and 65 on the edges 61 and 62 of the film constituting the package. This embodiment is also likely to be implemented in the case where the bi-oriented film is superimposed with another film, mono-oriented or bi-oriented.

La déchirure s'effectue au niveau de la zone de faiblesse 66 de la pièce de film rapportée 63 qui présente une force de rupture faible et inférieure à celle des soudures ou des zones de collage 64 et 65. Au niveau du conditionnement, les pièces de film 63 sont soudées ou collées avant la formation de l'emballage dans la machine « flow-pack ». Pour cela, il est possible d'utiliser le système décrit dans la demande de brevet EP 890 514 (GROUPE DANONE).The tear is effected at the level of the zone of weakness 66 of the reported film piece 63 which has a weak and weak breaking force than that of the welds or the bonding zones 64 and 65. At the level of the packaging, the pieces of film 63 are welded or glued before formation of the package in the flow-pack machine. For this, it is possible to use the system described in patent application EP 890 514 (DANONE GROUP).

Enfin, on peut réaliser également une zone de faiblesse au niveau d'un film (mono-orienté et/ou bi-orienté) en collant ou en soudant à plat en 73 (« cuir contre chair ») des bords en recouvrement périmétrique sur le pourtour de produit, (par exemple selon le périmètre 82 de la figure 8) référencés 71 et 72 du film. Dans ce cas, lors de la rupture du film, le délaminage des bords en recouvrement 71 et 72 s'effectue parallèlement à la surface des films sous l'effet de forces de cisaillement, qui rompent la liaison entre les bords en recouvrement 71 et 72, sur le pourtour du produit.Finally, it is also possible to make a zone of weakness at the level of a film (mono-oriented and / or bi-oriented) by gluing or welding flat 73 ("leather against flesh") edges in perimeter recovery on the around product, (for example according to the perimeter 82 of FIG. 8) referenced 71 and 72 of the film. In this case, during the breaking of the film, the delamination of the overlapping edges 71 and 72 is carried out parallel to the surface of the films under the effect of shearing forces, which break the connection between the overlapping edges 71 and 72. on the periphery of the product.

La figure 8 représente une variante de l'invention en technique « flow-pack ». Le repère 9 désigne les soudures d'extrémité et le repère 81, la soudure longitudinale « chair contre chair ». Une région périmétrique d'affaiblissement 82 peut être ménagée dans le film 3 pour induire une zone de rupture préférentielle dans la région centrale 4.FIG. 8 represents a variant of the invention in "flow-pack" technique. The reference 9 designates the end welds and the reference 81, the longitudinal weld "flesh against flesh". A perimetric weakening region 82 may be formed in the film 3 to induce a preferential breaking zone in the central region 4.
