Description

EMBALLAGE POUR LE CONDITIONNEMENT D'UN PRODUIT, NOTAMMENT ALIMENTAIRE  PACKAGING FOR PACKAGING A PRODUCT, IN PARTICULAR FOOD
L'invention concerne un emballage pour le conditionnement d'un produit, notamment alimentaire. The invention relates to a packaging for packaging a product, especially food.
Elle s'applique en particulier aux emballages destinés au conditionnement d'une portion individuelle de produit alimentaire fluide, par exemple un dessert de type compote ou yaourt, d'un sirop, d'un jus de fruit ou encore d'une dose de lait ou de café. It applies in particular to packaging intended for the packaging of an individual portion of fluid food product, for example a dessert of compote or yogurt type, a syrup, a fruit juice or a dose of milk or coffee.
On connaît des emballages comprenant un film souple dont les deux bords longitudinaux sont joints suivant une dorsale en formant un tube, les bords transversaux dudit tube étant ensuite associés pour délimiter un espace de conditionnement d'un produit. Packages are known comprising a flexible film whose two longitudinal edges are joined along a dorsal forming a tube, the transverse edges of said tube being then associated to delimit a packaging space of a product.
Pour permettre la distribution du produit conditionné, ces emballages sont classiquement agencés pour pouvoir être déchirés manuellement, notamment à proximité d'un bord transversal supérieur. To allow the distribution of the packaged product, these packages are conventionally arranged to be manually torn, especially near an upper transverse edge.
Pour ce faire, on connaît du document EP-0 312 393 un emballage formé d'un tube en film souple, dont le bord transversal supérieur est associé de manière à former une bordure étanche qui est disposée entre deux côtés dudit emballage, ladite bordure présentant une portion centrale dans laquelle est formé un évidement qui est en communication avec l'espace de conditionnement, une prédécoupe d'amorce de déchirure étant formée dans une portion latérale de ladite bordure en s'étendant transversalement en regard dudit évidement. For this purpose, it is known from EP-0 312 393 a package formed of a flexible film tube, the upper transverse edge of which is associated so as to form a sealed border which is arranged between two sides of said package, said edge presenting a central portion in which is formed a recess which is in communication with the conditioning space, a precut of tear primer being formed in a lateral portion of said border extending transversely opposite said recess.
Ainsi, pour ouvrir un tel emballage, on exerce une traction manuelle transversale sur la bordure au niveau de la prédécoupe, de manière à déchirer ladite bordure depuis un côté dudit emballage, la déchirure se propageant jusqu'à l'évidement, afin de créer, au travers dudit évidement, un orifice de distribution du produit conditionné. Toutefois, pour les emballages pourvus d'une dorsale, l'ouverture peut être difficile à réaliser ou être réalisée de façon imparfaite, en ce que ladite dorsale peut entraver la propagation de la déchirure. Thus, to open such a package, transverse manual traction is exerted on the rim at the precut, so as to tear said rim from one side of said package, the tear propagating to the recess, to create, through said recess, a dispensing orifice of the packaged product. However, for packages provided with a backbone, the opening may be difficult to achieve or imperfectly carried out, in that said backbone may hinder the propagation of the tear.
Le document US-5 371 997 propose un emballage dans lequel la dorsale s'étend depuis une portion latérale de la bordure supérieure à proximité d'un des côtés de l'emballage, une prédécoupe d'amorce de déchirure étant formée dans ladite dorsale et dans ladite portion latérale en s'étendant transversalement en regard de l'évidement. US-5,371,997 proposes a package in which the ridge extends from a lateral portion of the upper edge near one of the sides of the package, a pre-cut of tear primer being formed in said backbone and in said lateral portion extending transversely opposite the recess.
Ainsi, le fait de déporter la dorsale à proximité d'un côté de l'emballage et de former une prédécoupe d'amorce de déchirure à la fois dans ladite dorsale et dans la portion latérale de la bordure permet d'éviter que ladite dorsale ne résiste à la propagation de la déchirure de ladite bordure jusqu'à l'évidement, et donc de fiabiliser l'ouverture de l'emballage. Thus, deporting the dorsal near one side of the package and forming a pre-cut tear initiation both in said dorsal and in the lateral portion of the edge prevents the said dorsal resists propagation of the tear of said border to the recess, and thus to make reliable the opening of the package.
Toutefois, cette solution ne donne pas entière satisfaction, en ce qu'elle ne permet pas de garantir une déchirure maîtrisée de la bordure étanche, pourtant nécessaire à la formation d'un orifice adapté à une bonne distribution du produit. However, this solution is not entirely satisfactory, in that it does not guarantee a controlled tearing of the sealed edge, yet necessary for the formation of an orifice adapted to a good distribution of the product.
En effet, les emballages pour produit alimentaire sont généralement réalisés à partir d'un film souple ayant une structure stratifiée qui est agencée pour assurer la résistance mécanique dudit emballage avant son ouverture ainsi que la conservation du produit conditionné. Or, une telle structure peut s'avérer difficile à déchirer manuellement, tant par son épaisseur que par les matériaux qui la composent, et ce d'autant plus en relation avec la faible dimension de la bordure d'un emballage individuel. L'invention vise à perfectionner l'art antérieur en proposant notamment un emballage agencé pour permettre une déchirure facile et maîtrisée de sa bordure supérieure, afin de permettre la création d'un orifice optimisé pour une meilleure distribution du produit conditionné dans ledit emballage. A cet effet, l'invention propose un emballage pour le conditionnement d'un produit, notamment alimentaire, ledit emballage comprenant un film souple dont les deux bords longitudinaux sont joints suivant une dorsale en formant un tube dont les bords transversaux sont associés pour délimiter un espace de conditionnement, l'association du bord transversal supérieur formant une bordure étanche disposée entre deux côtés dudit emballage, ladite dorsale s'étendant depuis une première portion latérale de ladite bordure à proximité d'un desdits côtés, ladite bordure présentant une portion centrale dans laquelle est formée un évidement qui est en communication avec l'espace de conditionnement, une prédécoupe d'amorce de déchirure étant formée dans la dorsale et dans la première portion latérale en s'étendant transversalement en regard dudit évidement, la portion centrale de la bordure étant pourvue d'une ligne d'ablation qui est positionnée dans le prolongement transversal de la prédécoupe, ladite ligne d'ablation étant agencée pour permettre une propagation de la déchirure de la prédécoupe sur la portion centrale afin de créer, au travers de l'évidement, un orifice de distribution du produit conditionné. Indeed, food product packages are generally made from a flexible film having a laminated structure which is arranged to ensure the mechanical strength of said package before opening and the preservation of the packaged product. However, such a structure can be difficult to tear manually, both in its thickness and the materials that compose it, and all the more in relation to the small size of the border of an individual package. The invention aims to improve the prior art by providing in particular a package arranged to allow easy and controlled tearing of its upper edge, to allow the creation of an optimized orifice for a better distribution of the packaged product in said packaging. For this purpose, the invention proposes a packaging for packaging a product, especially food, said packaging comprising a flexible film whose two longitudinal edges are joined along a dorsal forming a tube whose transverse edges are associated to delimit a packaging space, the association of the upper transverse edge forming a sealed border disposed between two sides of said package, said dorsal extending from a first lateral portion of said border near one of said sides, said edge having a central portion in said which is formed a recess which is in communication with the conditioning space, a precut of tear initiation being formed in the dorsal and in the first lateral portion extending transversely opposite said recess, the central portion of the rim being provided with an ablation line which is positioned in the transv ersal of the pre-cut, said ablation line being arranged to allow propagation of the tear of the precut on the central portion to create, through the recess, a dispensing orifice of the packaged product.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe représentant schématiquement en vue de face une partie supérieure d'un emballage selon un mode de réalisation de l'invention. Other features and advantages of the invention will become apparent in the following description, made with reference to the attached figure schematically in front view of an upper portion of a package according to one embodiment of the invention.
En relation avec cette figure, on décrit ci-dessous un emballage pour le conditionnement d'un produit, notamment alimentaire, ledit emballage comprenant un film souple. In connection with this figure, there is described below a packaging for packaging a product, especially food, said packaging comprising a flexible film.
En particulier, l'emballage est destiné au conditionnement d'une portion individuelle de produit alimentaire fluide, par exemple un dessert de type compote ou yaourt, d'un sirop, d'un jus de fruit ou encore d'une dose de lait ou de café. In particular, the packaging is intended for the packaging of an individual portion of fluid food product, for example a dessert of compote or yoghurt type, a syrup, a fruit juice or a dose of milk or of coffee.
De façon avantageuse, le film souple présente une structure stratifiée qui comprend au moins une couche extérieure et une couche intérieure, les épaisseurs et/ou les matériaux respectifs desdites couches étant choisis pour leur fonction respective. Advantageously, the flexible film has a laminated structure which comprises at least one outer layer and one inner layer, the thicknesses and / or the respective materials of said layers being chosen for their respective function.
En particulier, la couche extérieure peut conférer la résistance mécanique à l'emballage, la couche intérieure permettant sa fermeture, notamment par soudage, mais également une bonne conservation du produit conditionné dans l'emballage tout en limitant les risques d'altération dudit produit par contact avec ladite couche intérieure. En particulier, dans le cas d'un produit alimentaire devant être conservé au réfrigérateur avant sa consommation, la structure stratifiée peut être agencée pour garantir au produit conditionné dans l'emballage une date limite de consommation (DLC) d'au moins quarante jours. Selon une réalisation, le film souple peut comprendre une couche extérieure à base de polytéréphtalate d'éthylène (PET) métallisé, par exemple avec une feuille d'aluminium, et une couche intérieure à base de polyéthylène (PE). In particular, the outer layer can confer mechanical strength to the package, the inner layer allowing its closure, in particular by welding, but also a good preservation of the packaged product in the package while limiting the risk of tampering of said product with contact with said inner layer. In particular, in the case of a food product to be stored in the refrigerator before consumption, the laminated structure can be arranged to ensure the product packaged in the package a Consumption Deadline (DLC) of at least forty days. In one embodiment, the flexible film may comprise an outer layer based on metallized polyethylene terephthalate (PET), for example with an aluminum foil, and an inner layer based on polyethylene (PE).
Selon les besoins, le film souple peut éventuellement comprendre au moins une couche additionnelle, notamment choisie parmi une couche barrière à base d'éthylène alcool vinylique (EVOH), qui permet notamment d'améliorer la perméabilité dudit film, et/ou une couche de polyéthylène (PE). Depending on the requirements, the flexible film may optionally comprise at least one additional layer, especially chosen from a barrier layer based on ethylene vinyl alcohol (EVOH), which makes it possible in particular to improve the permeability of said film, and / or a layer of polyethylene (PE).
Pour former l'emballage, les deux bords longitudinaux du film souple sont joints suivant une dorsale 1 , en formant un tube dont les bords transversaux sont ensuite associés pour délimiter un espace 2 de conditionnement d'une portion, notamment individuelle, de produit. En particulier, la dorsale 1 est formée par chevauchement des bords longitudinaux du film sur une largeur réduite, par exemple sur une dimension transversale di de l'ordre de 4 à 5 mm, puis association étanche dudit chevauchement. To form the package, the two longitudinal edges of the flexible film are joined along a dorsal 1, forming a tube whose transverse edges are then associated to define a space 2 for packaging a portion, particularly individual, of product. In particular, the dorsal 1 is formed by overlapping the longitudinal edges of the film over a reduced width, for example on a transverse dimension di of the order of 4 to 5 mm, then sealing association of said overlap.
En relation avec la figure, l'association du bord transversal supérieur 3 forme une bordure étanche 4 disposée entre deux côtés 5a, 5b de l'emballage. En particulier, pour un emballage destiné au conditionnement d'une portion individuelle de produit alimentaire, la bordure supérieure 4 s'étend entre les deux côtés 5a, 5b, par exemple sur une dimension transversale D d'environ 32 mm. Par ailleurs, la bordure 4 présente une dimension longitudinale qui est suffisante pour garantir la résistance mécanique de la fermeture de l'emballage, notamment relativement à son étanchéité sous compression de l'espace 2 de conditionnement, par exemple de l'ordre de 20 à 30 mm. En outre, une bordure analogue peut être formée au niveau de l'association du bord transversal inférieur du tube. In connection with the figure, the association of the upper transverse edge 3 forms a sealed border 4 disposed between two sides 5a, 5b of the package. In In particular, for a packaging intended for packaging an individual portion of food product, the upper edge 4 extends between the two sides 5a, 5b, for example on a transverse dimension D of about 32 mm. Furthermore, the edge 4 has a longitudinal dimension which is sufficient to guarantee the mechanical strength of the closure of the package, in particular with respect to its tightness under compression of the packaging space 2, for example of the order of 20 to 30 mm. In addition, a similar border may be formed at the level of the association of the lower transverse edge of the tube.
La dorsale 1 , la bordure supérieure 4 et/ou l'éventuelle bordure inférieure peuvent notamment être formées par soudure du film souple. La bordure supérieure 4 présente une portion centrale 4a dans laquelle est formé un évidement 6 qui est en communication avec l'espace de conditionnement 2, ledit évidement étant agencé pour permettre la création à travers lui d'un orifice de distribution du produit conditionné dans l'espace 2 après ouverture de l'emballage. En particulier, la portion centrale 4a est bordée de part et d'autre par une portion latérale 4c, 4b de la bordure supérieure 4. The dorsal 1, the upper edge 4 and / or the possible lower edge may in particular be formed by welding the flexible film. The upper edge 4 has a central portion 4a in which is formed a recess 6 which is in communication with the conditioning space 2, said recess being arranged to allow the creation through it of a dispensing orifice of the product conditioned in the space 2 after opening the package. In particular, the central portion 4a is bordered on both sides by a lateral portion 4c, 4b of the upper edge 4.
De façon avantageuse, l'évidement 6 ainsi que la portion centrale 4a présente une dimension transversale d4a d'environ 8 mm, ledit évidement étant centré entre les côtés 5a, 5b de l'emballage. La géométrie de l'évidement 6 est agencée pour pouvoir former un orifice de distribution suffisamment large pour assurer une bonne distribution du produit conditionné, et ce d'autant plus si ledit produit présente une viscosité importante, par exemple s'il s'agit d'un dessert réfrigéré de type yaourt ou compote, d'un sirop ou d'un jus de fruit. En relation avec la figure, la portion centrale 4a présente une partie non associée 7 formant l'évidement 6, ainsi qu'une partie associée 8 disposée entre le bord transversal supérieur 3 et ledit évidement 6, la dimension de ladite partie associée étant agencée pour maintenir l'étanchéité de la bordure 4 avant son ouverture. Advantageously, the recess 6 as well as the central portion 4a has a transverse dimension d4a of about 8 mm, said recess being centered between the sides 5a, 5b of the package. The geometry of the recess 6 is arranged to be able to form a sufficiently large dispensing orifice to ensure a good distribution of the packaged product, and all the more so if said product has a high viscosity, for example if it concerns a chilled dessert of yogurt or compote type, a syrup or a fruit juice. In relation to the figure, the central portion 4a has an unassociated portion 7 forming the recess 6, and an associated portion 8 disposed between the upper transverse edge 3 and said recess 6, the dimension of said portion. associated being arranged to maintain the tightness of the edge 4 before opening.
La bordure 4 comprend une première partie latérale 4b associée qui est disposée à proximité d'un côté 5a de l'emballage, ladite première portion latérale s'étendant depuis ledit côté adjacent jusqu'à l'évidement 6 et en se prolongeant par la partie associée 8. The border 4 comprises a first associated lateral portion 4b which is disposed near a side 5a of the package, said first lateral portion extending from said adjacent side to the recess 6 and extending through the portion associated 8.
Dans le mode de réalisation représenté, la bordure 4 comprend une deuxième portion latérale 4c associée qui s'étend depuis l'évidement 6 jusqu'au côté 5b de l'emballage opposé à la première portion latérale 4b, ce qui permet d'obtenir un évidement 6 centré dans la bordure 4, notamment en prévoyant deux portions latérales 4b, 4c de dimension transversale d4b, d4c analogue. En outre, le bord transversal supérieur 3 de la bordure 4 présente une zone supérieure qui est continûment associée entre les bords 5a, 5b de l'emballage, l'évidement 6 étant formé sous ladite zone supérieure. In the embodiment shown, the border 4 comprises a second associated lateral portion 4c which extends from the recess 6 to the side 5b of the package opposite the first lateral portion 4b, which makes it possible to obtain a recess 6 centered in the edge 4, in particular by providing two lateral portions 4b, 4c of transverse dimension d4b, d4c analog. In addition, the upper transverse edge 3 of the edge 4 has an upper zone which is continuously associated between the edges 5a, 5b of the package, the recess 6 being formed under said upper zone.
En particulier, pour un emballage destiné au conditionnement d'une portion individuelle de produit, les portions latérales 4b, 4c peuvent présenter chacune une dimension transversale d4b, d4c d'environ 12 mm, dans la mesure où la dimension transversale totale D de la bordure supérieure 4 est d'environ 32 mm et la dimension transversale d4a de l'évidement d'environ 8 mm. In particular, for a packaging intended for the packaging of an individual portion of product, the lateral portions 4b, 4c may each have a transverse dimension d4b, d4c of about 12 mm, insofar as the total transverse dimension D of the border upper 4 is about 32 mm and the transverse dimension d4a of the recess about 8 mm.
En variante non représentée, la bordure 4 peut ne comprendre que la première portion latérale 4b, l'évidement 6 s'étendant alors depuis ladite portion latérale unique jusqu'au côté 4b de l'emballage opposé à ladite portion latérale unique. As a variant not shown, the edge 4 may comprise only the first lateral portion 4b, the recess 6 then extending from said single lateral portion to the side 4b of the package opposite to said single lateral portion.
Pour faciliter l'ouverture de l'emballage, la dorsale 1 s'étend depuis la première portion latérale 4b à proximité d'un des côtés 5a de l'emballage, une prédécoupe 9a d'amorce de déchirure étant formée dans la dorsale 1 et dans ladite première portion latérale en s'étendant transversalement en regard dudit évidement. Le fait de déporter la dorsale 1 à proximité d'un côté 5a de l'emballage et de former une prédécoupe 9a d'amorce de déchirure à la fois dans ladite dorsale et dans la portion latérale 4b adjacente de la bordure 4 permet d'éviter que ladite dorsale, du fait de son épaisseur due à la superposition des bords longitudinaux du film souple et à l'éventuelle structure stratifiée dudit film, ne résiste à la propagation de la déchirure de ladite bordure. To facilitate the opening of the package, the dorsal 1 extends from the first lateral portion 4b near one of the sides 5a of the package, a pre-cut 9a of tear initiation being formed in the dorsal 1 and in said first lateral portion extending transversely opposite said recess. Deporting the dorsal 1 near a side 5a of the package and forming a pre-cut 9a tear initiation both in said dorsal and in the adjacent side portion 4b of the edge 4 avoids that said dorsal, due to its thickness due to the superposition of the longitudinal edges of the flexible film and to the possible laminated structure of said film, does not withstand the propagation of the tear of said border.
En particulier, la prédécoupe 9a d'amorce de déchirure peut s'étendre sur sensiblement toute la dimension transversale di de la dorsale 1 , ce qui permet d'éliminer totalement l'obstacle à la propagation de la déchirure formé par ladite dorsale. In particular, the pre-cut 9a tear initiation can extend over substantially the entire transverse dimension di of the dorsal 1, which allows to completely eliminate the obstacle to the propagation of the tear formed by said dorsal.
En relation avec la figure, la dorsale 1 comprend une ligne de pliure 10 reliant ladite dorsale à la première portion latérale 4b en délimitant des zones externe 1 1 a et interne 1 1 b de ladite portion latérale qui s'étendent respectivement depuis ladite ligne de pliure jusqu'au côté adjacent 5a de l'emballage et depuis ladite ligne de pliure jusqu'à l'évidement 6. In relation to the figure, the dorsal 1 comprises a fold line 10 connecting said dorsal to the first lateral portion 4b delimiting external zones 1 1 a and internal 1 1 b of said lateral portion which respectively extend from said line of folding to the adjacent side 5a of the package and from said fold line to the recess 6.
En particulier, le déport de la dorsale 1 est telle que la dimension transversale dua de la zone externe 1 1 a est de l'ordre de grandeur de la dimension transversal dub de la zone interne 1 1 b, par exemple en étant légèrement supérieure à elle sur la figure. In particular, the offset of the dorsal 1 is such that the transverse dimension of the outer zone 11a is of the order of magnitude of the transverse dimension of the internal zone 1b 1b, for example being slightly greater than she on the figure.
La prédécoupe 9a d'amorce de déchirure s'étend sur sensiblement toute la dimension transversale dua de la zone externe 1 1 a, ainsi l'utilisateur peut saisir conjointement ladite zone externe et la dorsale 1 pour ouvrir l'emballage. Par ailleurs, la prédécoupe 9a peut s'étendre également sur une partie de la zone interne 1 1 b, notamment pas jusqu'à l'évidement 6 pour fiabiliser l'étanchéité de la bordure 4 avant son ouverture. The pre-cut 9a tear initiation extends over substantially the entire transverse dimension of the outer zone 11a 1a, so the user can jointly enter said outer zone and the dorsal 1 to open the package. Furthermore, the precut 9a may also extend over a portion of the inner zone 1 1b, especially not until the recess 6 to make reliable the sealing of the edge 4 before opening.
Dans le mode de réalisation représenté, l'emballage comprend une deuxième prédécoupe 9b d'amorce de déchirure formée dans la deuxième portion latérale 4c, notamment en étant alignée transversalement avec la première prédécoupe 9a d'amorce de déchirure. In the embodiment shown, the package comprises a second pre-cut 9b of tear initiation formed in the second lateral portion 4c, in particular being aligned transversely with the first pre-cut 9a tear initiation.
En particulier, cette réalisation permet au consommateur de : In particular, this realization allows the consumer to:
- poursuivre la déchirure de l'emballage jusqu'à ladite deuxième prédécoupe afin de pouvoir retirer facilement toute la bordure supérieure avant consommation du produit, à la manière d'un bouchon ; et/ou - de pouvoir amorcer la déchirure de la bordure 4 par ladite deuxième prédécoupe en cas de difficulté d'ouverture à partir de ladite première prédécoupe.  continuing the tearing of the packaging until said second precut so as to be able to easily remove the entire upper rim before consumption of the product, in the manner of a stopper; and / or - to be able to initiate the tearing of the edge 4 by said second precut in case of difficulty of opening from said first precut.
Les prédécoupes 9a, 9b peuvent être formées mécaniquement, notamment au moyen d'un outil de découpe adapté, ledit outil pouvant en particulier être intégré sur la chaîne de production de l'emballage au niveau de l'unité d'association du bord supérieur 3, afin de pouvoir réaliser les prédécoupes 9a, 9b au moment de ladite association. The precuts 9a, 9b can be formed mechanically, in particular by means of a suitable cutting tool, said tool being able in particular to be integrated on the production line of the package at the upper edge association unit 3 , in order to be able to realize the precuts 9a, 9b at the time of said association.
En particulier, la dorsale 1 peut présenter une dimension transversale di comprise entre 4 mm et 5 mm, avec une précision de positionnement de l'ordre de 1 mm, afin de permettre la réalisation de la première prédécoupe 9a simultanément dans ladite dorsale et dans la première portion latérale 4b. In particular, the dorsal 1 may have a transverse dimension di of between 4 mm and 5 mm, with a positioning accuracy of the order of 1 mm, to allow the realization of the first precut 9a simultaneously in said dorsal and in the first lateral portion 4b.
Pour éviter que les prédécoupes 9a, 9b n'altèrent l'étanchéité de la bordure 4, les portions latérales 4b, 4c présentent chacune une zone 12b, 12c dépourvue de la prédécoupe 9a, 9b correspondante qui est disposée à proximité de l'évidement 6. To prevent the pre-cuts 9a, 9b from altering the tightness of the edge 4, the lateral portions 4b, 4c each have a zone 12b, 12c devoid of the corresponding precut 9a, 9b which is disposed near the recess 6 .
En particulier, une telle zone 12b, 12c peut s'étendre sur une dimension transversale d-i2t>, di2c d'au moins 5 mm pour garantir une étanchéité au niveau de l'évidement 6, ce qui permet, lorsque les portions latérales 4b, 4c associées présentent une dimension transversale de 12 mm, de réaliser une prédécoupe 9a, 9b sur une dimension transversale dga, dgb d'au plus 7 mm. S'agissant de la première portion latérale 4b, la zone 12b dépourvue de prédécoupe est formée sur la zone interne 1 1 b. En outre, selon le positionnement de la dorsale 1 , il est possible de décentrer la portion centrale 4a, et donc l'évidement 6, de quelques millimètres, afin de pouvoir réaliser une prédécoupe 9a de dimension transversale suffisamment importante pour assurer une bonne déchirure de la bordure 4 tout en gardant une dimension transversale di2b suffisante pour la zone non prédécoupée. In particular, such a zone 12b, 12c may extend over a transverse dimension d-i2t>, di2c of at least 5 mm to ensure a seal at the recess 6, which allows, when the lateral portions 4b , 4c associated have a transverse dimension of 12 mm, to perform a precut 9a, 9b on a transverse dimension dg a , dgb of at most 7 mm. With regard to the first lateral portion 4b, the zone 12b devoid of precut is formed on the inner area 1 1b. In addition, depending on the positioning of the dorsal 1, it is possible to off-center the central portion 4a, and thus the recess 6 by a few millimeters, in order to be able to make a pre-cut 9a of transverse dimension large enough to ensure a good tear of the border 4 while keeping a transverse dimension di2b sufficient for the non-pre-cut area.
La portion centrale 4a de la bordure 4 est en outre pourvue d'une ligne d'ablation 13 qui est positionnée dans le prolongement transversal de la première prédécoupe 9a, ladite ligne d'ablation étant agencée pour permettre une propagation de la déchirure de ladite prédécoupe sur ladite portion centrale afin de créer, au travers de l'évidement 6, un orifice de distribution du produit conditionné. The central portion 4a of the edge 4 is further provided with an ablation line 13 which is positioned in the transverse extension of the first precut 9a, said ablation line being arranged to allow propagation of the tear of said precut on said central portion to create, through the recess 6, a dispensing orifice of the packaged product.
En particulier, la deuxième prédécoupe 9b s'étend transversalement dans le prolongement de la ligne d'ablation 13, afin de permettre également, le cas échéant, une propagation de la déchirure sur ou depuis ladite deuxième prédécoupe. In particular, the second precut 9b extends transversely in the extension of the ablation line 13, to also allow, if necessary, propagation of the tear on or from said second precut.
Ainsi, la présence d'une telle ligne d'ablation 13 permet une déchirure maîtrisée de l'emballage, notamment au niveau de la portion centrale 4a dans laquelle l'évidement 6 est formé, pour la création d'un orifice optimisé pour une meilleure distribution du produit conditionné, et ce quelle que soit l'épaisseur et/ou la structure du film souple. Thus, the presence of such an ablation line 13 allows a controlled tearing of the package, especially at the central portion 4a in which the recess 6 is formed, for the creation of an optimized orifice for better distribution of the packaged product, regardless of the thickness and / or structure of the flexible film.
De façon avantageuse, la ligne d'ablation 13 peut être formée par application d'un rayon laser sur le film souple, ledit rayon étant ajusté, notamment en termes de puissance, pour permettre l'ablation d'une partie de l'épaisseur du matériau dudit film afin de former une ligne affaiblie le long de laquelle la déchirure peut se propager. En particulier, l'ablation n'est pas réalisée sur la totalité de l'épaisseur du film pour ne pas nuire à son étanchéité, notamment au niveau de l'évidement 6. En variante, la ligne d'ablation 13 peut être formée par application de moyens mécaniques sur le film souple, notamment par poinçonnement. Advantageously, the ablation line 13 may be formed by applying a laser beam to the flexible film, said radius being adjusted, in particular in terms of power, to allow a portion of the thickness of the film to be removed. material of said film to form a weakened line along which the tear can spread. In particular, the ablation is not performed on the entire thickness of the film to not impair its sealing, especially at the level of As a variant, the ablation line 13 may be formed by applying mechanical means to the flexible film, in particular by punching.
Dans le cas d'un film souple avec une structure stratifiée, la ligne d'ablation 13 peut être formée uniquement dans au moins une portion de l'épaisseur de la couche extérieure, afin de préserver l'étanchéité de l'évidement 6 avant ouverture de l'emballage. In the case of a flexible film with a laminated structure, the ablation line 13 can be formed only in at least a portion of the thickness of the outer layer, in order to preserve the tightness of the recess 6 before opening of the packaging.
La ligne d'ablation 13 peut présenter un motif discontinu, par exemple sous forme de tirets 13a, comme représenté sur la figure, ou sous forme de pointillés. En variante, la ligne d'ablation 13 peut présenter un motif continu. The ablation line 13 may have a discontinuous pattern, for example in the form of dashes 13a, as shown in the figure, or in dotted form. Alternatively, the ablation line 13 may have a continuous pattern.
De façon avantageuse, la ligne d'ablation 13 s'étend sur l'évidement 6, notamment sensiblement sur toute la dimension transversale d4a dudit l'évidement. En particulier, la ligne d'ablation 13 s'étend sur au moins une zone 12a, 12b dépourvue de prédécoupe des portions latérales 4b, 4c associées, afin de venir dans le prolongement transversal des prédécoupes 9a, 9b. Advantageously, the ablation line 13 extends over the recess 6, in particular substantially over the entire transverse dimension d4a of said recess. In particular, the ablation line 13 extends over at least one area 12a, 12b devoid of precut side portions 4b, 4c associated to come in the transverse extension of pre-cut 9a, 9b.
