Description

La présente invention se rapporte à une enveloppe d'emballage constituée d'un film destiné à être fermé par deux papillotes de part et d'autre d'un article à emballer ainsi qu'un procédé d'emballage d'un article à l'aide d'un tel emballage.The present invention relates to a packaging envelope consisting of a film intended to be closed by two twists on the side and other of an article to be packaged as well as a method of packaging a article using such packaging.

En particulier, l'invention relève du domaine de l'emballage des produits de confiserie.In particular, the invention relates to the field of packaging of confectionery products.

Généralement, les produits de confiserie sont emballés individuellement dans une portion de film préimprimé d'une taille et d'une forme appropriées, lesquels produits emballés individuellement pouvant à leur tour être conditionnés en vrac dans un sachet d'emballage d'une dimension appropriée. Typiquement, l'article à emballer est d'abord complètement enveloppé dans une portion de film rectangulaire et l'enveloppe ainsi formée est fermée par des papillotes en deux points situés de part et d'autre de l'article à emballer.Generally, confectionery products are packaged individually in a portion of pre-printed film of one size and of suitable form, which individually wrapped products which can in turn be packaged in bulk in a sachet packaging of an appropriate size. Typically, the article to first pack is completely wrapped in a serving of rectangular film and the envelope thus formed is closed by twists at two points located on either side of the article at wrap.

Dans le cadre de la présente invention, on entend par papillote le résultat de la fermeture par toronnage de ladite enveloppe.In the context of the present invention, the term "papillote" means result of the closure by stranding of said envelope.

Un problème important qui se pose à ce niveau est celui de la rétention de la papillote. Cette rétention ne peut être obtenue qu'au prix d'une sélection particulière du film utilisé en tant que substrat, qui doit présenter des caractéristiques mécaniques appropriées telles que la pliabilité ou, en particulier, une tendance prononcée à ne pas revenir à sa position initiale après le toronnage dudit film.An important problem at this level is that of retention of the foil. This retention can only be obtained price of a particular selection of the film used as a substrate, which must have appropriate mechanical characteristics such as that pliability or, in particular, a pronounced tendency not to return to its initial position after stranding said film.

En particulier, ce problème se manifeste lors de l'emballage d'articles de petites tailles et de section substantiellement ronde tels que les produits de confiserie comme par exemple les bonbons, les sucettes, les sucres d'orge, les pâtes de fruits, les barres chocolatées ou encore des produits plus volumineux comme les bouteilles, les rouleaux de pièces, ...In particular, this problem manifests itself during packaging articles of small size and of substantially round cross section such as that confectionery products such as candies, lollipops, barley sugars, fruit jellies, chocolate bars or even larger products such as bottles, rolls of coins, ...

Comme solution, il est connu de sélectionner des substrats particuliers connus pour leur pliabilité élevée, comme le papier paraffiné ou la cellophane ou encore des films synthétiques renfermant une quantité appropriée d'un additif augmentant la pliabilité dudit substrat. As a solution, it is known to select substrates individuals known for their high foldability, such as paper paraffin or cellophane or synthetic films containing an appropriate amount of an additive increasing the foldability of said substrate.

Cette solution limite considérablement les possibilités de choix de films utilisés comme substrat d'emballage et en augmente considérablement le coût.This solution considerably limits the possibilities of choice of films used as packaging substrate and increases it considerably the cost.

On connaít sur le marché des emballages fermés par des papillotes qui sont réalisées à partir de substrats préalablement revêtus d'un enduit de scellage à chaud. Lors de la formation de papillotes aux extrémités de l'enveloppe contenant l'article à emballer, on approche pendant un certain laps de temps une source de chaleur à température comprise entre 120 et 160°C environ. Généralement, ce sont les mâchoires effectuant le toronnage qui sont chauffées, mais il est également possible de souffler de l'air chaud au moyen d'un tube de dimension appropriée sur lesdites papillotes, ce qui a pour conséquence la fusion de l'enduit de scellage à chaud et le scellage de la papillote ainsi formée lors du refroidissement dudit enduit de scellage à chaud.We know on the market of packaging closed by papillotes which are produced from substrates beforehand coated with a heat seal coating. During the training of foil at the ends of the envelope containing the article to be packaged, we approach a heat source for a certain period of time at a temperature between approximately 120 and 160 ° C. Usually, it is the jaws performing the stranding that are heated, but it is also possible to blow hot air using of a tube of appropriate size on said papillotes, which has as a result the fusion of the heat sealing coating and the sealing of the foil thus formed during the cooling of said hot sealing coating.

Le document GB-A-1096058 propose un film avec un enduit de scellage à froid qui, après fermeture de l'enveloppe par toronnage des papillotes, présente une excellente rétention. Cet enduit de scellage à froid se présente sous forme de deux bandes longitudinales situées dans les zones de formation des papillotes de part et d'autre de l'article à emballer.Document GB-A-1096058 proposes a film with a coating of cold sealing which, after closing the envelope by stranding the papillotes, has excellent retention. This sealing coating to cold is in the form of two longitudinal strips located in the areas of formation of papillotes on either side of the item to be packaged.

Par scellage à froid, on entend un scellage qui s'effectue instantanément par simple contact à une température comprise entre 0 et 50°C environ. En réalité, la température n'est pas un paramètre critique quant à l'obtention d'un scellage au moyen d'un enduit de scellage à froid et n'a pratiquement pas d'influence sur la qualité du scellage obtenu. On effectue donc le scellage sans qu'un apport de chaleur supplémentaire à la température ambiante de l'espace dans le quel se trouve l'unité d'emballage ne soit nécessaire.By cold sealing is meant a sealing which takes place instantly by simple contact at a temperature between 0 and 50 ° C approximately. In reality, temperature is not a parameter critical of obtaining a seal with a coating of cold sealing and has practically no influence on the quality of the sealing obtained. We therefore carry out the sealing without a contribution of extra heat at room temperature the space in the what is the packaging unit is needed.

Cette méthode permet donc l'utilisation de films moins chers et présentant de meilleures propriétés (rigidité, propension à l'impression, qualités esthétiques) pour l'emballage d'articles sans restrictions quant à la forme ou la sensibilité à la chaleur desdits articles.This method therefore allows the use of cheaper films and with better properties (rigidity, propensity to printing, aesthetic qualities) for packaging articles without restrictions on the shape or sensitivity to heat of said articles.

Le but de la présente invention est de prévoir un nouvel emballage du type à fermeture par papillote qui permet une meilleure fermeture que les emballages actuellement connus, ainsi qu'un nouveau procédé d'emballage.The object of the present invention is to provide a new packaging of the type with papillote closure which allows a better closure as currently known packaging, as well as a new packaging process.

Pour atteindre cet objectif, la présente invention prévoit une enveloppe d'emballage constituée d'un film destiné à être fermé par deux papillotes de part et d'autre d'un article à emballer, caractérisée en ce que le film comporte, du côté intérieur par rapport à l'article à emballer, un enduit de scellage disposé suivant deux bandes transversales de part et d'autre de l'article à emballer et s'étendant parallèlement à un axe passant par les deux papillotes.To achieve this objective, the present invention provides a packaging envelope made of a film intended to be closed by two twists on either side of an article to be packaged, characterized in that the film has, on the inner side with respect to the article to be packing, a sealing plaster arranged in two strips transverse on either side of the article to be wrapped and extending parallel to an axis passing through the two twists.

Ledit enduit de scellage peut être un enduit de scellage à froid ou un enduit de scellage à chaud.Said sealer may be a cold sealer or a heat seal coating.

Le film peut comporter, en outre, deux bandes longitudinales d'enduit de scellage s'étendant de part et d'autre de l'article à emballer, perpendiculairement auxdites bandes transversales dans les zones de formation des papillotes. Ces enduits de scellage peuvent également être, soit des enduits de scellage à froid, soit des enduits de scellage à chaud. Lorsque le substrat du film possède une faible résistance aux températures élevées et/ou lorsque l'article à emballer est sensible à la chaleur, notamment les produits de chocolaterie, l'enduit de scellage à froid mérite la préférence.The film may also have two longitudinal strips sealing plaster extending on either side of the article to pack, perpendicular to said transverse bands in the papillote formation areas. These sealants can also be either cold sealing plasters or plasters heat seal. When the film substrate has low resistance to high temperatures and / or when the article to be packaged is sensitive to heat, especially chocolate products, cold seal coating deserves preference.

L'enduit de scellage à chaud peut être une couche de PE (polyéthylène) coextrudé sur de l'OPP (oriented polypropylène).The heat seal coating can be a layer of PE (polyethylene) coextruded on OPP (oriented polypropylene).

Comme enduit de scellage à froid, on peut envisager les adhésifs sensibles à la pression qui sont des substances qui sont collantes d'une manière permanente et qui adhèrent spontanément à la surface de la plupart des matériaux sous l'effet d'une simple pression modérée.As a cold sealing coating, we can consider adhesives pressure sensitive which are substances that are sticky permanently and that spontaneously adhere to the surface of most materials at the touch of a button moderate.

En règle générale, les adhésifs sensibles à la pression sont des compositions à base de caoutchouc naturel et/ou synthétique associées à des cellophanes modifiées, des résines phénolformaldéhydes ou des résines hydrocarbonées (cires). Outre les caoutchoucs, on utilise largement des polymères à base de styrène, d'acide (méth)acrylique ou d'éther de vinyle, seuls ou en mélange, également en combinaison avec des résines. Enfin, on peut encore utiliser des résines silicones. On utilise de préférence des compositions comprenant des mélanges de caoutchoucs naturels et synthétiques et des copolymères de l'acide (méth)acrylique et du styrène.Generally, pressure sensitive adhesives are compositions based on natural and / or synthetic rubber associated with modified cellophanes, phenolformaldehyde resins or hydrocarbon resins (waxes). Besides the rubbers, polymers based on styrene are widely used, (meth) acrylic acid or vinyl ether, alone or as a mixture, also in combination with resins. Finally, we can still use silicone resins. Preferably, compositions comprising mixtures of natural rubbers and synthetic and copolymers of (meth) acrylic acid and styrene.

Ces enduits de scellage à froid sont déposés sur le substrat à raison de 1 à 5 g/m2 environ. Ils peuvent être appliqués sous forme de solution, de dispersion ou même à l'état fondu. On peut utiliser les techniques de dépôt d'enduit bien connues de l'homme du métier telles que, par exemple, l'impression héliographique ou flexographique ou encore l'impression offset.These cold sealing coatings are deposited on the substrate at a rate of approximately 1 to 5 g / m 2 . They can be applied as a solution, dispersion or even in the molten state. One can use plaster deposition techniques well known to those skilled in the art such as, for example, heliographic or flexographic printing or offset printing.

L'invention propose également un procédé d'emballage d'un article dans un film comprenant au moins deux bandes transversales d'un enduit de scellage selon lequel on dépose l'article sur le film du côté des dites bandes et entre celles-ci, on relève substantiellement verticalement les deux pans qui sont munis desdites bandes d'enduit, on rapproche au dessus de l'article les deux pans et on scelle leur bord l'un à l'autre, on rabat les deux bords ainsi scellés sur l'article et on toronne les projections du film dépassant de part et d'autre de l'article pour former deux papillotes.The invention also provides a method of packaging a article in a film comprising at least two transverse bands a sealing coating according to which the article is deposited on the film of the side of said bands and between them, there is substantially vertically the two panels which are provided with said plaster strips, we bring the two sides together above the article and seal their edge to edge, the two edges thus sealed are folded over the article and we screen the projections of the film projecting on either side of the article to form two twists.

Lorsque les bandes d'enduit comportent un enduit de scellage à froid, l'opération de pliage et de scellage des bords des bandes au dessus de l'article se fait de préférence en une seule opération entre les mâchoires d'une presse.When the plaster strips have a cold, the operation of folding and sealing the edges of the strips at above the article is preferably done in a single operation between the jaws of a press.

Lorsque l'enduit est un enduit de scellage à chaud, les bords sont scellés l'un à l'autre par un procédé de thermoscellage.When the coating is a heat seal coating, the edges are sealed to each other by a heat sealing process.

L'invention présente l'avantage que, pour la première fois, l'emballage du type fermeture à papillotes est scellé dans le sens transversal entre les deux papillotes. Etant donné que, même les emballages sans enduction longitudinale dans les zones de formation des papillotes, présentent une étanchéité assez bonne au niveau des papillotes, on réalise ainsi des emballages complètement fermés.The invention has the advantage that, for the first time, the packaging of the twist closure type is sealed in the direction transverse between the two twists. Since even packaging without longitudinal coating in the training areas papillotes, have a fairly good seal at the papillotes, completely closed packages are produced.

Quant aux emballages pourvus de zones longitudinales d'enduit de scellage à chaud ou froid, pour lesquels il y a une fermeture étanche au niveau des papillotes, on réalise grâce au scellage transversal une fermeture quasi-hermétique. Cette fermeture totale de l'emballage est très avantageuse quant à la conservation des articles, puisqu'elle empêche la pénétration d'humidité, de gaz, d'air ou d'autres substances nuisibles et, en même temps, conserve les arômes à l'intérieur de l'emballage.As for packages with longitudinal plaster zones hot or cold sealing, for which there is a closure waterproof at the papillotes, it is achieved thanks to the sealing transverse an almost hermetic closure. This total closure of the packaging is very advantageous as regards the conservation of the articles, since it prevents the penetration of humidity, gas, air or other harmful substances and, at the same time, retains the aromas inside the packaging.

La figure 1 montre une bande de film indiquée globalement par la référence 10 qui est un film avec une bonne rétention où seul le toronnage suffit pour obtenir une papillote rigide qui ne s'ouvre pas, c'est à dire un substrat qui ne nécessite pas d'enduction de collage pour retenir les papillotes. Un tel film peut, par exemple, être un film cellophane, un film PP coulé (polypropylène coulé), du papier paraffiné, un contre-collage alu/OPP etc.Figure 1 shows a film strip generally indicated by the reference 10 which is a film with good retention where only the stranding is sufficient to obtain a rigid foil which does not open, i.e. a substrate that does not require bonding coating to retain the twists. Such a film can, for example, be a film cellophane, cast PP film (cast polypropylene), paper waxed, aluminum / OPP lamination etc.

Les articles à emballer sont représentés en pointillés par la référence 12. La bande de film 10 est destinée à être coupée selon les lignes 14 pour fournir des pièces de film 16 identiques entre elles qui jouent le rôle d'enveloppes d'emballage pour les articles 12. Sur la figure 1 on a également représenté en pointillés la silhouette des papillotes 18 obtenues par toronnage des projections de part et d'autre de l'article à emballer 12.The articles to be packaged are represented by dotted lines by the reference 12. The film strip 10 is intended to be cut according to the lines 14 to supply identical pieces of film 16 which act as packaging envelopes for items 12. On the Figure 1 is also shown in dotted lines the silhouette of 18 foils obtained by stranding the projections of part and other of the article to be packaged 12.

Conformément à la présente invention, la bande de film 10 comporte des enductions de scellage 20 s'étendant dans le sens transversal de la bande sur le côté intérieur par rapport aux articles 12 à emballer. Ces bandes 20 sont disposées à cheval sur les lignes de coupe 14 de sorte qu'après découpage de la bande de film 10 chaque pièce individuelle 16 comporte le long de ses bords deux bandes transversales 20a, 20b d'enduit de scellage.According to the present invention, the film strip 10 has sealing coatings 20 extending in the direction transverse of the strip on the inner side with respect to articles 12 to pack. These bands 20 are arranged astride the lines of cut 14 so that after cutting the film strip 10 each individual piece 16 has two strips along its edges 20a, 20b sealing plaster.

Dans l'exemple représenté sur la figure 1 l'enduit de scellage est un enduit de scellage à froid, par exemple le produit 22-392 de la société CRODA qui est déposé à raison de 3g/m2.In the example shown in FIG. 1, the sealing coating is a cold sealing coating, for example the product 22-392 from the company CRODA which is deposited at the rate of 3 g / m 2 .

La figure 2 montre un second mode de réalisation d'un film d'emballage 40 selon la présente invention. Ce film 40 est constitué de coexOPP (coextruded oriented polypropylène) qui à lui seul ne possède pas de propriétés de rétention des papillotes 18. Pour pouvoir néanmoins former ces papillotes 18 le film est revêtu dans les deux zones de formation des papillotes 18 sur le côté intérieur par rapport au produit à emballer 12 de deux bandes longitudinales 42, 44 d'une enduction de collage à froid qui peut être constituée par le même matériel que celui des bandes transversales 20 du mode de réalisation de la figure 1. Le mode de réalisation de la figure 2 comporte des bandes transversales 46 d'enduction de scellage à chaud qui, après découpage du film forment le long des bords de chaque pièce des bandes transversales 46a et 46b. Ces bandes transversales d'enduit de scellage à chaud peuvent être formées par une couche de PE coextrudé sur l'OPP.Figure 2 shows a second embodiment of a film 40 according to the present invention. This film 40 is made up of coexOPP (coextruded oriented polypropylene) which alone does not does not have retention properties for 18 papillotes. be able nevertheless to form these twists 18 the film is coated in the two papillote formation zones 18 on the inner side by relative to the product to be packaged 12 of two longitudinal strips 42, 44 of a cold bonding coating which can be constituted by the same material as that of the transverse bands 20 of the embodiment of Figure 1. The embodiment of Figure 2 has transverse strips 46 of sealing coating to hot which after cutting the film form along the edges of each piece of transverse bands 46a and 46b. These bands transverse heat seal plaster can be formed by a layer of PE coextruded on the OPP.

Il est à noter que différentes combinaisons sont possibles entre les modes de réalisation selon les figures 1 et 2. C'est ainsi par exemple que les bandes transversales d'enduit de scellage à froid de la figure 1 peuvent être remplacées par des bandes transversales d'enduit de scellage à chaud. De même, les bandes de scellage à chaud 46 de la figure 2 peuvent être remplacées par des bandes de scellage à froid. Par ailleurs, il est possible qu'aussi bien les bandes longitudinales 42, 44 de la figure 2 que les bandes transversales 46 soient constituées toutes soit d'enduit de scellage à chaud, soit d'enduit de scellage à froid.Note that different combinations are possible between the embodiments according to FIGS. 1 and 2. It is thus by example that the transverse strips of cold sealing plaster of Figure 1 can be replaced by transverse bands hot sealing plaster. Likewise, the sealing strips at warm 46 of Figure 2 can be replaced by strips of cold sealing. Furthermore, it is possible that both the bands longitudinal 42, 44 of Figure 2 that the transverse bands 46 all consist of either heat sealing plaster or cold sealing plaster.

Les figures 3a à 3d ainsi que les figures 4a à 4d illustrent les différentes phases successives d'un procédé d'emballage conformément à la présente invention à l'aide d'un emballage tel que décrit ci dessus en référence aux figures 1 ou 2. L'article 12 est posé sur l'une des pellicules 16 à l'intérieur des bandes transversales 20a et 20b. Sur les figures on a représenté, à titre d'exemple, les pièces de film 16 de la figure 1 mais il est entendu que le procédé s'applique aussi bien au film de la figure 2 ainsi qu'aux différentes combinaisons possibles. Les deux pans latéraux A et B avec les bandes transversales d'enduit de scellage 20a et 20b sont ensuite repliées vers le haut tel que représenté sur les figures 3a et 4a. On replie ensuite les deux pans A et B simultanément vers l'intérieur sur l'article 12 de manière à ce que leurs bords intérieurs avec les bandes transversales 20a et 20b se placent l'un contre l'autre comme représenté sur la figure 4b. On exerce ensuite comme représenté sur la figure 5 une pression sur l'extérieur de chacun des bords des pans A et B sur toute la largeur pour bien sceller ensemble ces deux pans au niveau de leur enduit de scellage à froid. Cette opération de pliage des pans A et B et de scellage de leur bord peut être effectuée en une seule opération entre les mâchoires d'une presse 48 (figure 3b). On obtient ainsi une nervure de scellage 50 qui s'étend sur toute la largeur, tel que représentée sur les figures 3c et 4b. Cette nervure est ensuite pliée et rabattue sur l'emballage selon les figures 3d et 4c, de préférence, en exerçant une pression verticale selon la figure 6 pour conférer à l'emballage une présentation attractive. L'emballage est terminé en toronnant les deux extrémités dans le sens du rabattement de la nervure 50 pour former deux papillotes 18 selon la figure 4d.Figures 3a to 3d as well as Figures 4a to 4d illustrate the different successive phases of a packaging process in accordance to the present invention using a package as described above above with reference to Figures 1 or 2. Article 12 is placed on one films 16 inside the transverse bands 20a and 20b. The figures show, by way of example, the pieces of film 16 of FIG. 1 but it is understood that the method also applies well to the film of figure 2 as well as the different combinations possible. The two side panels A and B with the bands transverse sealing plaster 20a and 20b are then folded upwards as shown in Figures 3a and 4a. We fold then the two sides A and B simultaneously inward on the article 12 so that their inner edges with the bands cross 20a and 20b are placed one against the other as shown in Figure 4b. We then exercise as shown on Figure 5 a pressure on the outside of each of the edges of the sides A and B over the entire width to seal these two sides together at the level of their cold sealing coating. This folding operation sections A and B and sealing of their edge can be carried out in one single operation between the jaws of a press 48 (Figure 3b). We thus obtains a sealing rib 50 which extends over the entire width, as shown in Figures 3c and 4b. This rib is then folded and folded over the packaging according to Figures 3d and 4c, of preferably, exerting vertical pressure according to figure 6 to give the packaging an attractive presentation. The packaging is finished by twisting the two ends in the direction of the drawdown of the rib 50 to form two twists 18 according to Figure 4d.

Grâce à la présence des bandes transversales 20a, 20b d'enduit de scellage à froid et grâce à la mise en oeuvre de pression, on obtient une fermeture parfaite sur toute la largeur de l'emballage. Les papillotes 18 assurent, en outre, surtout lorsqu'elles sont effectuées au niveau de bandes longitudinales 42 et 44 d'enduit de scellage selon la figure 2 une fermeture latérale. On réalise ainsi un emballage quasi-hermétique qui empêche la sortie des arômes ou la pénétration d'air, d'humidité, d'odeurs néfastes etc...Thanks to the presence of the transverse strips 20a, 20b of plaster cold sealing and thanks to the use of pressure, obtains a perfect closure over the entire width of the packaging. The 18 foils, moreover, especially when carried out at the level of longitudinal strips 42 and 44 of sealing plaster according to Figure 2 a side closure. This produces packaging quasi-hermetic which prevents the release of aromas or penetration air, humidity, harmful odors etc ...

Dans le cas de bandes transversales d'enduit de scellage à chaud les mâchoires de la presse 48 peuvent être chauffées à une température de l'ordre de 150° pour obtenir un scellage parfait entre les bandes 20a et 20b. Il est également possible de souffler de l'air chaud (± 150-180°C) sur les deux bords avant de les sceller ensemble dans la presse.In the case of transverse strips of hot sealing plaster the jaws of the press 48 can be heated to a temperature of the order of 150 ° to obtain a perfect seal between bands 20a and 20b. It is also possible to blow air hot (± 150-180 ° C) on both edges before sealing them together in the press.
