Description

La présente invention a pour objet un emballage formé, associant un flan en papier ou en carton et un film superposés, entourant un empilement de produits rigides.The present invention relates to a formed package, associating a blank of paper or cardboard and a superimposed film, surrounding a stack of rigid products.

De tels emballages sont couramment utilisés dans le domaine des techniques agroalimentaires pour emballer en particulier des produits tels que les biscuits.Such packages are commonly used in the field of agri-food techniques for packaging especially products such as biscuits.

Pour réaliser une ouverture d'un tel conditionnement, on utilise en général une bande d'arrachage qui permet de découper le film sur son périmètre et de dégager l'extrémité supérieure du conditionnement, en donnant ainsi accès aux produits. Un tel emballage est divulgué dans le document US2926833.To achieve an opening of such a package, it is generally used a tear strip which can cut the film on its perimeter and clear the upper end of the packaging, thereby giving access to the products. Such a package is disclosed in US2926833.

Ce type de conditionnement présente un certain nombre d'inconvénients.This type of packaging has a number of disadvantages.

Tout d'abord, et notamment dans le cas d'un conditionnement de forme cylindrique, et du fait que le flan, généralement en carton ondulé entoure de manière étroite les produits, le prélèvement de biscuit n'est pas particulièrement aisé. En outre, un tel conditionnement n'est pas compatible avec une refermeture efficace, ce qui fait que le contenu du paquet une fois ouvert doit être rapidement consommé.First, and particularly in the case of a cylindrical form of packaging, and the fact that the blank, generally corrugated cardboard closely surrounds the products, the biscuit levy is not particularly easy. In addition, such packaging is not compatible with an effective reclosing, so that the contents of the package once opened must be quickly consumed.

La présente invention concerne un dispositif de conditionnement présentant un bon niveau d'étanchéité et permettant un accès facile aux produits, et éventuellement une refermeture facile.The present invention relates to a packaging device having a good level of tightness and allowing easy access to products, and possibly an easy reclosing.

Dans ce but, l'invention concerne un emballage formé qui entoure un empilement de produits rigides, et associant un flan en papier ou en carton et un film superposés caractérisé en ce que le flan présente une zone de découpe définissant une région de préhension des produits et en ce que le film présente une bande qui lui est solidaire et qui recouvre au moins partiellement ladite zone de découpe, le film et la bande formant un dispositif d'ouverture permettant de dégager la zone de découpe, le prélèvement de produits successifs pouvant s'effectuer par gravité en plaçant l'emballage debout.For this purpose, the invention relates to a formed package which surrounds a stack of rigid products, and associating a blank of paper or cardboard and a film superimposed characterized in that the blank has a cutting zone defining a gripping region of the products. and in that the film has a band which is integral with it and which at least partially covers said cutting area, the film and the strip forming an opening device for clearing the cutting area, the sampling of successive products being able to perform by gravity by placing the package upright.

La présence de la zone de découpe ménagée dans le flan permet d'utiliser tout dispositif d'ouverture, avantageusement refermable, apte à dégager la zone de découpe et à permettre un accès aux produits.The presence of the cutting zone formed in the blank makes it possible to use any opening device, advantageously resealable, capable of clearing the cutting area and allowing access to the products.

En effet, le flan en papier ou en carton permet d'assurer une rigidité suffisante de l'emballage en position debout et de former une sorte de distributeur autoportant, même en tenant compte de l'affaiblissement localisé que procure la zone de découpe.Indeed, the blank made of paper or cardboard makes it possible to ensure sufficient rigidity of the packaging while standing and to form a sort of self-supporting dispenser, even taking into account the localized weakening provided by the cutting zone.

La bande solidaire du film peut présenter une couche adhésive solidarisant la bande et le flan en dehors de la zone de découpe. Ceci permet en particulier de réaliser une refermeture de l'emballage.The strip integral with the film may have an adhesive layer that secures the strip and the blank outside the cutting zone. This allows in particular to achieve a reclosing of the package.

Selon un mode de réalisation permettant également une refermeture de l'emballage, le flan présente une portion de bande collante recouverte d'une bande de protection, qui est disposée par exemple au voisinage d'un bord de la découpe ou d'un bord du flan.According to one embodiment also allowing the packaging to be reclosed, the blank has a portion of sticky tape covered with a protective band, which is arranged for example in the vicinity of an edge of the blank or an edge of the blank. blank.

La bande peut s'étendre d'un premier bord à un deuxième bord opposé du film.The strip may extend from a first edge to a second opposite edge of the film.

Selon un mode de réalisation avantageux, le contour du flan s'inscrit dans le contour du film, et le flan et le film sont superposés de manière à laisser, au moins à une extrémité, une marge permettant au film de former par repliement au moins un fond de paquet. Le flan et le film peuvent être superposés de manière à présenter un bord commun.According to an advantageous embodiment, the contour of the blank fits into the contour of the film, and the blank and the film are superimposed so as to leave, at least at one end, a margin allowing the film to form by folding at least a package background. The blank and the film may be superimposed so as to have a common edge.

Il est avantageux que ladite bande déborde d'au moins un côté du flan.It is advantageous for said strip to overflow at least one side of the blank.

Le film peut présenter une bande en surépaisseur qui longe ladite bande solidaire du film, de manière à limiter la déchirure du film, en direction d'une extrémité du film, en particulier une extrémité qui forme un fond du paquet.The film may have a thickened strip which runs along said strip integral with the film, so as to limit the tearing of the film, towards one end of the film, in particular an end which forms a bottom of the pack.

Selon un mode de réalisation préféré, le dispositif est caractérisé en ce que le film présente une languette découpée venant sensiblement en correspondance avec la zone de découpe et en ce que la bande solidaire du film est constituée par une étiquette qui adhère au film sur une surface en débord de la languette découpée du film de manière à former un dispositif d'ouverture - refermeture.According to a preferred embodiment, the device is characterized in that the film has a cut tab substantially corresponding to the cutting area and in that the strip integral with the film is constituted by a label which adheres to the film on a surface in excess of the cut tab of the film so as to form an opening device - reclosing.

L'emballage peut être cylindrique ou parallélépipédique, et au moins un fond de l'emballage peut être au moins en partie constitué par un repliement du film le long d'un bord dudit flan.The package may be cylindrical or parallelepipedic, and at least one bottom of the package may be at least in part constituted by a folding of the film along an edge of said blank.

Le film peut présenter une région qui déborde du flan et qui vient en recouvrement avec le film, avec soudure le long de la ligne de soudure.The film may have a region that overflows the blank and that overlaps with the film, with welding along the weld line.

Il est particulièrement avantageux de disposer une région d'amorce de déchirure sur la ligne de soudure.It is particularly advantageous to have a tear initiation region on the weld line.

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

  • les figures 1 a et 1b illustrent la première variante de l'invention dans laquelle le flan est muni d'une découpe, la figure 2 illustrant un mode de mise en oeuvre sous forme d'un emballage formé cylindrique, qui peut être ouvert conformément aux figures 3 et 4 ;
  • les figures 5a et 5b illustrent la deuxième variante de l'invention, la figure 6 illustrant un mode de mise en oeuvre sous forme d'un emballage formé cylindrique, représenté en position ouverte ;
  • Les figures 7a et 7b illustrent une autre variante dans laquelle le flan est pourvu d'une prédécoupe en pointillés ou autre ;
  • les figures 8 et 9 illustrent un mode de mise en oeuvre sous forme d'un emballage formé cylindrique qui peut être ouvert conformément aux figures 3 et 4.
Other features and advantages of the invention will appear better on reading the following description, given by way of non-limiting example, in connection with the drawings in which:
  • FIGS. 1a and 1b illustrate the first variant of the invention in which the blank is provided with a cutout, FIG. 2 illustrating an embodiment in the form of a cylindrical shaped package, which can be opened in accordance with FIGS. Figures 3 and 4;
  • Figures 5a and 5b illustrate the second variant of the invention, Figure 6 illustrating an embodiment in the form of a cylindrical shaped packaging, shown in the open position;
  • FIGS. 7a and 7b illustrate another variant in which the blank is provided with a dashed or other precut;
  • Figures 8 and 9 illustrate an embodiment in the form of a cylindrical shaped package that can be opened in accordance with Figures 3 and 4.

Conformément aux figures 1 a et 1 b qui représentent la première variante de l'invention, le flan 1 en papier ou en carton, et plus particulièrement en papier ou en carton ondulé présente une ouverture constituée par une découpe 16 de largeur l et de longueur l0 permettant la sortie des produits, par exemple des biscuits. Pour un paquet cylindrique, la longueur l0 est au moins égale au demi-périmètre du paquet. Pour des produits prélevés latéralement, la largeur l est supérieure ou égale à leur hauteur. L'ouverture du paquet s'effectue en tirant le film 2 notamment en matière plastique, en particulier en polyoléfine, d'épaisseur par exemple de quelques dizaines de microns, grâce à une amorce de déchirure, par exemple des découpes 27, situées par exemple au niveau de la soudure longitudinale 25 du paquet.In accordance with FIGS. 1 a and 1 b which represent the first variant of the invention, the blank 1 made of paper or cardboard, and more particularly of paper or corrugated cardboard, has an opening constituted by a cutout 16 of width l and of length l 0 to the output of products, eg biscuits. For a cylindrical package, the length l 0 is at least equal to the half-perimeter of the package. For products taken laterally, the width l is greater than or equal to their height. The package is opened by pulling the film 2, in particular made of plastic, in particular polyolefin, of thickness for example of a few tens of microns, thanks to a tear initiation, for example cuts 27, located for example at the longitudinal seam 25 of the package.

La bande 3 peut n'être solidarisée qu'au film 2, mais de manière préférentielle elle peut être solidarisée également au flan 1 en dehors de la découpe 16. En outre, la partie de la bande 3 en débord longitudinal du flan 1 au-delà du bord 14 de celui-ci, peut être également revêtu d'une couche collante permettant une refermeture du paquet après usage.The strip 3 may be secured only to the film 2, but preferably it may also be secured to the blank 1 outside the cut-out 16. In addition, the portion of the strip 3 in the longitudinal edge of the blank 1 may beyond the edge 14 thereof, may also be coated with a tacky layer for reclosing the package after use.

Dans le cas représenté où la bande 3 n'est solidarisée qu'au film 1, il est avantageux de munir le flan 1, au voisinage de son bord 14 (ou d'un bord 18 de la découpe 18), d'une pièce de bande collante 17 pourvue d'une protection appropriée. Après la première ouverture du paquet, on enlève la protection de la pièce de bande collante 17, de manière à permettre une refermeture facile de l'emballage.In the case shown where the strip 3 is secured to the film 1, it is advantageous to provide the blank 1, in the vicinity of its edge 14 (or an edge 18 of the blank 18), a piece sticky tape 17 provided with appropriate protection. After opening the package for the first time, removes the protection of the piece of adhesive tape 17, so as to allow easy reclosing of the package.

Dans le mode de réalisation représenté, la bande 3 est une bande simple face collée sur la face interne du film 2 et au même niveau que la découpe 16 du flan 1. La fonction de la bande 3 est de permettre la déchirure du film 2 en dehors du périmètre de la découpe 16. En effet, les films sont en général en matériaux pour lesquels la direction de propagation d'une déchirure n'est pas exactement prévisible. Avec la bande 3, la déchirure ne s'écarte que peu des bords de la bande 3, tout en ne pouvant en pénétrer le périmètre.In the embodiment shown, the strip 3 is a single-sided strip bonded to the inner face of the film 2 and at the same level as the blank 16 of the blank 1. The function of the strip 3 is to allow the tearing of the film 2 Outside the perimeter of the cut-out 16. In fact, the films are generally made of materials for which the direction of propagation of a tear is not exactly predictable. With the band 3, the tear deviates little from the edges of the band 3, while not being able to penetrate the perimeter.

La longueur l0 de la découpe est supérieure ou égale au demi-périmètre du biscuit et sa hauteur l est supérieure ou égale à celle d'un biscuit, ce dans le cas d'un emballage cylindrique.The length l 0 of the cut is greater than or equal to the half-perimeter of the biscuit and its height l is greater than or equal to that of a biscuit, in the case of a cylindrical packaging.

Pour fabriquer l'emballage, la dépose de la bande collante 3 se fait directement sur le film 1. La découpe de l'ouverture 16 sur le flan 1 peut être réalisée soit en même temps que la coupe du contour du flan 1 selon sa longueur ou de façon séparée. La dépose de la pièce de bande collante protégée 17 se fait avant ou après la découpe du contour du flan 1 et/ou de l'ouverture 16.To manufacture the package, the removal of the adhesive tape 3 is done directly on the film 1. The cutting of the opening 16 on the blank 1 can be carried out at the same time as the cutting of the contour of the blank 1 according to its length or separately. The removal of the piece of protected adhesive tape 17 is done before or after cutting the contour of the blank 1 and / or the opening 16.

Il est à noter qu'une bande collante de faible épaisseur 4 peut être placée en dessous de la bande 3 qui sert à l'ouverture dans le but de contrôler le sens et l'orientation de la déchirure dans le cas d'un film 2 en polymère biorienté, de manière à éviter que la déchirure ne se dirige vers le fond du paquet.It should be noted that a thin adhesive strip 4 may be placed below the strip 3 used for opening in order to control the direction and orientation of the tear in the case of a film 2 bioriented polymer, so that the tear does not go to the bottom of the package.

Le consommateur saisit le film 2 et la bande collante 3 au niveau des découpes 27 et déchire de manière périmétrique le film de manière à venir dégager la découpe 16 et à permettre un accès aux produits 40, par exemple des biscuits (voir les figures 3 et 4), ce qui permet d'assurer une préhension et un prélèvement latéral de ceux-ci dès que la longueur dégagée de la découpe 16 atteint le demi-périmètre du paquet cylindre. La région de préhension 16 ainsi dégagée étant située au voisinage d'un fond du paquet (par exemple à une distance égale à l'épaisseur d'un, deux, voire trois produits), les biscuits peuvent être prélevés par gravité en plaçant le paquet debout.The consumer grasps the film 2 and the adhesive tape 3 at the cutouts 27 and tears perimetrically the film so as to come clear the cutout 16 and to allow access to the products 40, for example biscuits (see FIGS. 4), which ensures a gripping and a lateral sampling thereof as soon as the unobstructed length of the cutout 16 reaches the half-perimeter of the cylinder package. The gripping region 16 thus released being located in the vicinity of a bottom of the package (for example at a distance equal to the thickness of one, two or even three products), the biscuits can be removed by gravity by placing the package standing.

Une distance égale à l'épaisseur d'au moins un produit entre la région de préhension 16 et le fond du paquet permet d'assurer une rigidité suffisante malgré la découpe 16.A distance equal to the thickness of at least one product between the gripping region 16 and the bottom of the pack makes it possible to ensure sufficient rigidity despite cutting 16.

Conformément aux figures 5a et 5b, le film 2 présente une languette découpée 30 par exemple rectangulaire. La languette 30 est avantageusement découpée sur un périmètre non fermé, par exemple sur trois côtés découpés 31, 32 et 33, en laissant subsister une ligne d'articulation 36 de la languette 30 au film 2 entre les extrémités 34 et 35 des côtés 31 et 33.According to Figures 5a and 5b, the film 2 has a cut tab 30, for example rectangular. The tongue 30 is advantageously cut on an unclosed perimeter, for example on three cut sides 31, 32 and 33, leaving a hinge line 36 of the tongue 30 to the film 2 between the ends 34 and 35 of the sides 31 and 33.

Pour faciliter le passage sur machine et notamment le défilement de flan 2 lors de la mise en forme de l'emballage, les côtés découpés 31, 32, et 33 sont avantageusement solidarisés en des points 37 au flan 2. Ces points 37 offrent une résistance négligeable lors de l'ouverture.To facilitate the passage on the machine and in particular the scroll of blank 2 during the shaping of the package, the cut sides 31, 32, and 33 are advantageously secured at points 37 to the blank 2. These points 37 provide resistance negligible when opening.

La bande solidaire du film 2 est constituée par une étiquette 50 ayant une face interne collante superposée à la languette découpée 30 comme représenté à la figure 5b. L'étiquette 50 présente deux bords 51 et 52 qui sont espacés des bords 31 et 33 de la languette 30, en dehors du périmètre de celle-ci. De même une région de préhension 53, avantageusement non collante sur sa face interne, est espacée du bord 32 de la languette 30, en dehors du périmètre de celle-ci.The strip secured to the film 2 is constituted by a label 50 having a sticky inner surface superimposed on the cut tab 30 as shown in Figure 5b. The label 50 has two edges 51 and 52 which are spaced from the edges 31 and 33 of the tongue 30, outside the perimeter thereof. Similarly, a gripping region 53, advantageously non-sticky on its inner face, is spaced from the edge 32 of the tongue 30, outside the perimeter of the latter.

Avantageusement, la languette 53 est bordée au moins en partie par des lignes d'affaiblissement 55 (par exemple des pointillés ou des lignes de faible résistance) qui servent notamment de témoin d'inviolabilité de l'emballage.Advantageously, the tongue 53 is bordered at least in part by weakening lines 55 (for example dotted lines or lines of low resistance) which serve in particular to tamper proof the package.

Avantageusement, des lignes d'affaiblissement, par exemple des prédécoupes 57, bordent une ligne 54 d'articulation de l'étiquette 50 située à l'aplomb de la ligne 36 ou légèrement au-delà de celle-ci hors du périmètre de la languette 30.Advantageously, lines of weakness, for example pre-cuts 57, border a line 54 of articulation of the label 50 located directly above the line 36 or slightly beyond it outside the perimeter of the tongue. 30.

Pour ouvrir l'emballage, l'utilisateur saisit le bord 53 de l'étiquette 50 et déploie celle-ci comme représenté à la figure 6 en entraînant la languette 30 dont la face externe est solidaire par collage de la face interne de l'étiquette 50, ce qui dégage la découpe 16 du flan 1 et permet l'accès aux produits.To open the package, the user grasps the edge 53 of the label 50 and deploys it as shown in FIG. 6 by driving the tongue 30, the external face of which is secured by gluing the internal face of the label. 50, which releases the cutout 16 of the blank 1 and allows access to the products.

La variante illustrée par les figures 7a et 7b met en oeuvre une bande collante 3 pour associer deux matériaux, à savoir un flan 1 en papier ou en carton, et plus particulièrement en papier ou en carton ondulé et un film 2 notamment en matière plastique, en particulier en polyoléfine, dont l'épaisseur est en général de quelques dizaines de microns. Le flan 1 et le film 2 sont solidarisés au niveau d'une prédécoupe 15 réalisée sur le flan 1. Une amorce à la déchirure réalisée en particulier au niveau de la soudure longitudinale du paquet formé, permet, en tirant le film de découper celui-ci tout en déchirant la prédécoupe 15 du flan 1. Le mouvement s'effectue sur toute ou partie de la longueur l2 du flan 1 de manière à permettre un accès aux produits, par exemple des biscuits. La refermeture peut s'effectuer par application de la bande adhésive 3 en débord du flan 1 contre le film 2 sur laquelle elle est repliée, par exemple au niveau de la soudure longitudinale 25 du paquet formé.The variant illustrated in FIGS. 7a and 7b implements a sticky strip 3 for combining two materials, namely a blank 1 made of paper or cardboard, and more particularly of paper or corrugated cardboard and a film 2 in particular of plastic, in particular polyolefin, whose thickness is generally a few tens of microns. The blank 1 and the film 2 are secured at a precut 15 made on the blank 1. A tear primer made in particular at the longitudinal weld of the formed package, allows, by pulling the film to cut it ci while tearing the precut 15 of the blank 1. The movement is performed on all or part of the length l 2 of the blank 1 so as to allow access to the products, for example biscuits. The reclosing can be carried out by applying the adhesive strip 3 in overflow of the blank 1 against the film 2 on which it is folded, for example at the longitudinal seam 25 of the package formed.

La bande collante 3 présente une largeur inférieure ou égale à la distance entre les prédécoupes 15 sur le flan 1 et peut être :

  • un ruban transfert (protection/colle/protection) ou bien une couche de colle déposée entre le flan 1 et le film 2,
  • une bande double-face (protection/colle-support-colle/protection), une face collante étant au contact avec le film 2 et l'autre face étant en contact avec le flan 1,
  • une bande simple face avec un support soudant (colle-support soudant), la face collante étant au contact avec le flan 1 et la face non-collante mais soudante étant soudée sur le film 2, l'adhésion entre le support et le film se faisant par soudure, thermique ou non, sur une partie ou la totalité de la bande collante.
The adhesive strip 3 has a width less than or equal to the distance between the pre-cuts 15 on the blank 1 and may be:
  • a transfer tape (protection / adhesive / protection) or a layer of adhesive deposited between the blank 1 and the film 2,
  • a double-sided tape (protection / adhesive-support-glue / protection), one sticky face being in contact with the film 2 and the other face being in contact with the blank 1,
  • a single-sided tape with a weldable support (soldering glue-support), the sticky face being in contact with the blank 1 and the non-sticky but weldable face being welded to the film 2, the adhesion between the support and the film is by welding, heat or not, on part or all of the adhesive tape.

La prédécoupe 15' de largeur l (par exemple deux lignes de prédécoupe pointillées 15 ou deux lignes de réduction d'épaisseur) est réalisée sur une partie ou sur la totalité de la longueur l2 du flan du paquet, et en tous cas sur une longueur suffisante pour le prélèvement des produits. La largeur l est également dimensionnée en fonction des produits. Pour des biscuits prélevés latéralement, elle est supérieure ou égale à la hauteur des biscuits.The precut 15 'of width (e.g., two dotted lines of weakness 15 or two thickness reduction lines) is formed on a part or all of the length l 2 of the package blank, and in any case on a sufficient length for the collection of products. The width l is also dimensioned according to the products. For biscuits taken laterally, it is greater than or equal to the height of the biscuits.

Dans le cas d'un ruban transfert ou d'une bande double-face, la dépose de la bande collante peut s'effectuer d'abord sur un des deux matériaux avec enlèvement de la protection avant mise en contact avec l'autre matériau.In the case of a transfer tape or a double-sided tape, the removal of the adhesive tape can be done first on one of the two materials with removal of the protection before contact with the other material.

Dans le cas d'une bande simple face avec support soudant, la pose du ruban adhésif s'effectue premièrement sur le flan 1.In the case of a single-sided tape with solder support, the adhesive tape is first applied to the blank 1.

Dans le cas d'un ruban transfert ou d'une bande double-face, la longueur de la bande collante 3 déposée est inférieure ou égale à la longueur L2 du film 2 utilisé pour l'emballage.In the case of a transfer ribbon or a double-sided tape, the length of the adhesive tape 3 deposited is less than or equal to the length L 2 of the film 2 used for packaging.

Dans le cas d'une bande simple-face avec support soudant, la longueur de la bande collante déposée 3 est inférieure ou égale à la longueur l2 du flan 1.In the case of a single-sided strip with solder support, the length of the adhesive tape deposited 3 is less than or equal to the length l 2 of the blank 1.

Dans le mode de réalisation des figures 7a et 7b, le flan 1 présente une largeur l1 et une longueur l2 et la prédécoupe 15' de largeur l s'étend d'un bord d'extrémité 11 à l'autre bord d'extrémité 14, parallèlement aux côtés longitudinaux 12 et 13, en restant espacée d'une distance m du bord 13. L'assemblage du flan 1 et du film 2 est réalisé en faisant coïncider les bords 11 et 21 respectivement du flan 1 et du film 2 tout en laissant des marges inférieure et supérieure M1 et M2 permettant un repliement du film 2 pour former au moins partiellement un fond de paquet à chaque extrémité.In the embodiment of FIGS. 7a and 7b, the blank 1 has a width l 1 and a length l 2 and the pre-cut 15 'of width 1 extends from one end edge 11 to the other edge of the blank. end 14, parallel to the longitudinal sides 12 and 13, remaining spaced a distance m from the edge 13. The assembly of the blank 1 and the film 2 is made by coinciding the edges 11 and 21 respectively of the blank 1 and the film 2 while leaving lower and upper margins M 1 and M 2 allowing a folding of the film 2 to at least partially form a bottom package at each end.

Le film 2 présente une largeur L1 et une longueur L2, cette longueur L2 étant préférentiellement supérieure à la longueur I2 du flan 1 de manière que la bande collante 3 et le film puissent déborder pour permettre un collage du film sur lui-même, la longueur l2 du flan 1 correspondant sensiblement au périmètre du paquet formé autour des produits. A la figure 1b, on voit également que la bande 3 est disposée de manière à recouvrir partiellement ou totalement la région prédécoupée 15 du flan 1.The film 2 has a width L 1 and a length L 2 , this length L 2 preferably being greater than the length I 2 of the blank 1 so that the adhesive tape 3 and the film can overflow to allow the film to stick to it. same, the length l 2 of the blank 1 substantially corresponding to the perimeter of the package formed around the products. In FIG. 1b, it can also be seen that the strip 3 is arranged so as to partially or completely cover the pre-cut region 15 of the blank 1.

Enfin, à une extrémité de la bande en débord du flan 1, est ménagée une amorce de déchirure, par exemple des découpes 27. Dans l'exemple représenté, ces découpes 27 partent du bord 24 du film 2.Finally, at one end of the strip beyond the blank 1, is provided a tear initiation, for example cuts 27. In the example shown, these cutouts 27 start from the edge 24 of the film 2.

La figure 8 illustre le cas d'un emballage cylindrique, notamment pour des biscuits ronds dans le cas où la longueur de la bande collante 3 est égale à la longueur du film 2. Les découpes 27, qui ici jouxtent le bord 24 du film 2, sont ménagées au niveau de la soudure longitudinale 25 du paquet dont les fonds sont réalisés par repliement des extrémités du film 2 qui dépassent des bords 12 et 13 du flan 2.FIG. 8 illustrates the case of a cylindrical package, in particular for round biscuits in the case where the length of the adhesive strip 3 is equal to the length of the film 2. The cutouts 27, which here abut the edge 24 of the film 2 are formed at the longitudinal seam 25 of the pack whose bottoms are made by folding the ends of the film 2 which protrude from the edges 12 and 13 of the blank 2.

Le consommateur saisit le film 2 et la bande collante 3 au niveau des découpes 27 et déchire de manière périmétrique le film et les prédécoupes 15 de manière à venir dégager les produits 40, par exemple des biscuits (voir les figures 3 et 4), ce qui permet d'assurer une préhension et un prélèvement latéral de ceux-ci dès que la longueur de prédécoupe déchirée atteint le demi-périmètre du paquet cylindrique. La région de préhension 15' ainsi dégagée étant située au voisinage d'un fond du paquet, les biscuits peuvent être prélevés par gravité en plaçant le paquet debout.The consumer grasps the film 2 and the adhesive tape 3 at the cutouts 27 and perimetrically rips the film and pre-cuts 15 so as to come off the products 40, for example biscuits (see FIGS. 3 and 4), which which makes it possible to ensure gripping and lateral removal of these as soon as the torn precut length reaches the half-perimeter of the cylindrical bundle. The gripping area 15 ' thus released being located near a bottom of the package, the biscuits can be removed by gravity by placing the package upright.

La figure 9 illustre le cas où la longueur de la bande collante 3 est égale à la longueur l2 du flan 1. Dans ce cas, les prédécoupes 27 peuvent toujours être réalisées au niveau de la soudure longitudinale 25 mais le début de l'ouverture s'effectuant en tirant sur le film 2 seul jusqu'à ce que la déchirure rejoigne le bord 14 du flan 1 pour déchirer ensuite l'ensemble du film 2 et de la prédécoupe 15' pour dégager les produits 40 comme dans le cas de la figure 2.FIG. 9 illustrates the case where the length of the adhesive strip 3 is equal to the length l 2 of the blank 1. In this case, the pre-cuts 27 can always be made at the longitudinal seam 25 but the beginning of the opening by pulling on the film 2 alone until the tear reaches the edge 14 of the blank 1 to then tear the entire film 2 and the precut 15 'to release the products 40 as in the case of the figure 2.

On comprendra que, dans le cas d'un emballage cylindrique, la longueur de la prédécoupe peut être supérieure ou égale au demi-périmètre de l'emballage, alors que dans un emballage de forme carrée ou rectangulaire, la longueur de la prédécoupe peut être supérieure ou égale à la longueur d'un côté de l'emballage ceci afin d'assurer le prélèvement des produits.It will be understood that, in the case of a cylindrical package, the length of the precut may be greater than or equal to the half-perimeter of the package, while in a square or rectangular package, the length of the precut may be greater than or equal to the length of one side of the packaging to ensure the collection of products.
