- Folding is accomplished by passing the sheet through a cylindrical sleeve-shaped tool called a bend stack or bending chamber. If the sheet is of the type shown in FIG. 7, it is heated at the time of folding to a temperature sufficient to allow the wax to flow under the effect of folding.
- the small folds allow to easily aboserber surplus material related to the passage of a flat disc to a cylinder. They also bring a certain vertical rigidity to the cylinder thus formed and an attractive aesthetic to the packaging. Finally, they allow a total opening of the cylinder by unfolding all the folds.
- the sheet After passing the wrapping sheet in the folding tool, the sheet has the shape of a receiving cup (of the type shown in Figure 13, relating to the second folding mode). It is freestanding and retains this shape. It is then transferred into a receptacle of substantially cylindrical shape. The cheese is deposited in the leaf while it is in the receptacle.
- the lid 7 is placed on the free surface of the cheese.
- the label 43 is glued to the sheet 41 of the lid before cutting said sheet, for example in an aluminum coil. It is thus easier to deposit and achieve sufficient masking of the label on the sheet.

- the fingers 65 hold the lid 7 pressed against the cheese along a line 67 connecting the upright edge 37 and the central portion 36.
- Several inner fingers 65 are distributed on the periphery of the lid.
- the fingers 65 each have a bent end that supports the erected edge of the lid against the side wall 23 of the sheet.
- Other outer fingers 69 are distributed around the packaging assembly.
- the fingers 69 press radially against the peripheral edge 39 of the packaging sheet.
- the fingers 69 exert stress on the peripheral edge 39 from the outside to the inside. Under the effect of this constraint, the peripheral edge 39 and the erected edge 37 fall back on the central portion 36 of the lid.
- the fingers 65 are then released by a radial movement towards the center of the lid.
- the fingers 65 and 69 are arranged facing each other, so that the stress exerted by the fingers 69 on the peripheral edge of the packaging sheet is not transmitted to the bottom in the other areas of the wall side and does not cause deformation of the side wall.
- the fingers 65 define rigid areas in the side wall, around which the peripheral edge 39 will bend. In the absence of the fingers 65, the stresses exerted by the fingers 69 would not cause a sharp folding of the peripheral edges but on the contrary a general deformation of the wall, because the cheese has a soft texture. Folding is completed by a pressing step by means of a cylindrical piston on the top of the cheese, to completely fold the edge 39 on the lid.
- the user When the user wants to repack the cheese, it first puts the lid on the top of the cheese and reform the sheet around the cheese.
- the gripping tabs 47 formed on the peripheral edge of the sheet allow the user to deploy the sheet without getting dirty hands and without the fingers come into contact with the cheese. These tabs are indeed shifted towards the center of the lid, in an area that is not likely to include cheese particles. Similarly, the user does not have to grip the edge of the lid to lift it and remove it. He grasps the grasping organ, and pulls on it. This body is shifted towards the center of the lid, so that the user does not dirty the fingers.

Description
Ensemble de conditionnement de produits à texture pâteuse ou semi-liquide. Set of packaging products with pasty or semi-liquid texture.
La présente invention concerne en général les ensembles de conditionnement notamment pour produits pâteux ou semi-liquides, leur procédé de fabrication et les produits conditionnés obtenus. The present invention generally relates to packaging assemblies, in particular for pasty or semi-liquid products, their manufacturing process and the packaged products obtained.
De manière générale, l'invention s'applique au conditionnement de produits pâteux ou semi-liquides et en particulier à des produits alimentaires tels que des fromages frais, des fromages fondus et toutes spécialités fromagères présentant un caractère pâteux ou semi-liquide au moment du conditionnement. In general, the invention applies to the packaging of pasty or semi-liquid products and in particular to food products such as fresh cheeses, processed cheeses and all cheese specialties having a pasty or semi-liquid character at the time of the invention. conditioning.
Dans la description qui suit, on entend par fromages ou spécialités fromagères les produits issus de la transformation du lait en fromages, que ces produits soient constitués totalement de matières premières d'origine laitière ou mélangés avec des matières premières d'origine végétale (protéines , matières grasses , céréales , etc.). In the description which follows, cheese or cheese specialties are products derived from the processing of milk into cheese, whether these products consist entirely of raw materials of dairy origin or mixed with raw materials of vegetable origin (proteins, fats, cereals, etc.).
L'invention concerne les fromages qui présentent un caractère pâteux ou semi-liquide au moment du conditionnement. The invention relates to cheeses which have a pasty or semi-liquid character at the time of packaging.
Plus précisément, l'invention concerne selon un premier aspect un ensemble de conditionnement du type comprenant : More specifically, the invention relates in a first aspect to a packaging assembly of the type comprising:
- une feuille d'emballage ; - a wrapping sheet;
- une dose de produit emballé dans la feuille d'emballage, le produit ayant une texture pâteuse ou semi-liquide mais préférentiellement pâteuse au moment du conditionnement dans la feuille d'emballage, la feuille d'emballage étant pliée de manière à définir un fond et une paroi latérale circonférentielle, la feuille d'emballage présentant un bord périphérique rabattu d'un côté du fromage opposé au fond ; a dose of product packaged in the packaging sheet, the product having a pasty or semi-liquid texture but preferentially pasty at the time of packaging in the packaging sheet, the packaging sheet being folded so as to define a bottom and a circumferential side wall, the wrapping sheet having a peripheral edge folded on one side of the cheese opposite the bottom;
- un opercule posé sur le fromage et pris entre le bord périphérique de la feuille d'emballage et le fromage. - A lid placed on the cheese and caught between the peripheral edge of the packaging sheet and the cheese.
II est connu de longue date de conditionner les produits alimentaires dans des récipients utilisant différents types de matériau : aluminium, papier, matériau plastique souple ou rigide, etc. De façon particulière l'invention concernera des récipients en matériau souple. It has long been known to package food products in containers using different types of material: aluminum, paper, flexible or rigid plastic material, etc. In particular, the invention will relate to containers made of flexible material.
En particulier, il est connu de conditionner les fromages frais vendus sous le nom Boursin ou Saint Agur dans un emballage de ce type, dans lequel la feuille d'emballage est pliée de manière à obtenir une forme générale cylindrique. La paroi latérale de la feuille comporte un grand nombre de plis serrés, appelés aussi soufflets, destinés à absorber le surplus de matière résultant de la mise en forme. Ces plis apportent une rigidité à l'ensemble de conditionnement, et confèrent à celui-ci une esthétique intéressante.
L'emballage est difficile à ouvrir sans se salir les doigts. L'utilisateur doit d'abord relever le bord périphérique de la feuille, pour accéder à l'opercule. Il doit ensuite saisir l'opercule par son bord libre. Ses doigts viennent fréquemment au contact du fromage ou du sérum au cours de ce mouvement. In particular, it is known to package the fresh cheeses sold under the name Boursin or Saint Agur in a packaging of this type, in which the packaging sheet is folded so as to obtain a generally cylindrical shape. The side wall of the sheet has a large number of tight folds, also called bellows, to absorb the excess material resulting from shaping. These folds provide rigidity to the packaging assembly, and give it an attractive aesthetic. The packaging is difficult to open without getting your fingers dirty. The user must first raise the peripheral edge of the sheet to access the lid. He must then seize the operculum by its free edge. His fingers frequently come into contact with cheese or serum during this movement.

L'ensemble de conditionnement représenté sur les Figures 1 et 2 est préférentiellement destiné à l'emballage de fromage présentant un caractère pâteux ou semi-liquide au moment du conditionnement. On peut citer dans cette catégorie les fromages frais tels que celui commercialisé sous la marque Boursin ® ou les fromages appartenant à la famille des fromages fondus à tartiner ayant une texture pâteuse au moment du conditionnement dans la feuille d'emballage. The packaging assembly shown in FIGS. 1 and 2 is preferably intended for packaging cheese having a pasty or semi-liquid character at the time of packaging. In this category, mention may be made of fresh cheeses such as that marketed under the trademark Boursin® or cheeses belonging to the family of processed soft cheeses having a pasty texture at the time of packaging in the packaging sheet.
L'ensemble de conditionnement comporte : The packaging set comprises:
- une feuille d'emballage 3 ; a packaging sheet 3;
- une dose de fromage 5 emballée dans la feuille d'emballage (voir Figure 2) ; - un opercule 7.
La feuille d'emballage 3 est pliée de manière à former une coupelle de réception pour le fromage. Plus précisément, la feuille d'emballage 3 est pliée de manière à définir un fond 21 (visible sur la figure 13) et une paroi latérale circonférentielle 23 solidaire du fond. La feuille définit ainsi un logement ouvert à l'opposé du fond 21 . a dose of cheese packaged in the wrapping sheet (see Figure 2); - a cover 7. The wrapping sheet 3 is folded to form a receiving cup for the cheese. More specifically, the packaging sheet 3 is folded so as to define a bottom 21 (visible in Figure 13) and a circumferential side wall 23 integral with the bottom. The sheet thus defines an open housing opposite the bottom 21.
La feuille d'emballage pliée présente une forme sensiblement cylindrique. The folded packing sheet has a substantially cylindrical shape.
La dose de fromage 3 présente typiquement également une forme sensiblement cylindrique. L'opercule 7 est apposé sur une face de la dose de fromage opposée au fond 21 . The cheese dose 3 also typically has a substantially cylindrical shape. The lid 7 is affixed to one side of the cheese dose opposite the bottom 21.
La feuille d'emballage 3 est pliée comme décrit dans FR 2 575 140. La feuille d'emballage 3 est pliée de manière à définir un fond sensiblement plat et une paroi latérale circonférentielle 23 comportant une multitude de plis 75, appelés aussi soufflet. La paroi latérale circonférentielle présente au moins dix soufflets, de préférence au moins 20 soufflets, et typiquement au moins 50 soufflets. Chaque soufflet 75 s'étend du fond 21 jusqu'au bord périphérique 39 de la feuille. Chaque soufflet comporte typiquement deux ailes formant un V pointant vers l'extérieur de l'emballage. Les soufflets 75 sont placés circonférentiellement dans le prolongement les uns des autres, et sont directement raccordés les uns aux autres. The wrapping sheet 3 is folded as described in FR 2 575 140. The wrapping sheet 3 is folded so as to define a substantially flat bottom and a circumferential side wall 23 having a multitude of plies 75, also called bellows. The circumferential side wall has at least ten bellows, preferably at least 20 bellows, and typically at least 50 bellows. Each bellows 75 extends from the bottom 21 to the peripheral edge 39 of the sheet. Each bellows typically has two wings forming a V pointing outwardly of the package. The bellows 75 are placed circumferentially in the extension of each other, and are directly connected to each other.
Comme visible sur la Figure 2, l'opercule 7 présente une partie centrale 36 plaquée contre le fromage, et un bord 37 rabattu contre la partie centrale 36, à l'opposé du fromage. La feuille 3 présente un bord périphérique 39, prolongeant la paroi latérale 23 à l'opposé du fond 21 et rabattu sur le bord 37 et sur la partie centrale 36. (Figure 1 ) As shown in Figure 2, the lid 7 has a central portion 36 pressed against the cheese, and an edge 37 folded against the central portion 36, opposite the cheese. The sheet 3 has a peripheral edge 39, extending the side wall 23 opposite the bottom 21 and folded over the edge 37 and the central portion 36. (Figure 1)
Avant de rabattre, on peut réaliser optionnellement un scellage du bord périphérique 39 avec le bord 37 de l'opercule. Before folding down, it is possible optionally to seal the peripheral edge 39 with the edge 37 of the lid.
L'opercule 7 comporte une feuille en un matériau métallique 41 et une étiquette 43 collée sur ladite feuille 41 . La feuille 41 est typiquement une feuille d'aluminium, ou d'un alliage d'aluminium. Cette feuille reçoit un vernis ou une laque ou une enduction plastique sur chacune de ses faces pour permettre un contact direct avec le produit emballé. Ce vernis ou laque ou enduction pourra optionnellement avoir des qualités permettant un scellage pelable avec la feuille d'emballage. L'étiquette 43 est typiquement en papier ou préférentiellement en matière plastique. Elle est collée sur une face de la feuille 41 opposée au fromage. Elle peut porter un décor, par exemple un décor imprimé, sur sa face visible opposée au fromage. L'étiquette 43 comporte une languette 45 dépourvue de colle, ou dans laquelle la colle a été neutralisée, ou au niveau de laquelle le papier support de l'adhésif (généralement un papier siliconé souvent nommé backing par les anglo-saxons) a été conservé. La languette 45 est libre par rapport à la feuille 41 . Elle constitue un organe de préhension (voir Figure 3) que l'utilisateur peut saisir entre deux
doigts. Elle peut adopter une position inclinée par rapport à la feuille 41 , pour que l'utilisateur puisse facilement exercer un effort tendant à décoller l'opercule du fromage. The cover 7 comprises a sheet of a metal material 41 and a label 43 stuck on said sheet 41. The sheet 41 is typically an aluminum foil, or an aluminum alloy. This sheet receives a varnish or a lacquer or a plastic coating on each of its faces to allow direct contact with the packaged product. This varnish or lacquer or coating may optionally have qualities allowing a peelable seal with the packaging sheet. The label 43 is typically paper or preferably plastic. It is stuck on one side of the sheet 41 opposite the cheese. It may carry a decoration, for example a printed decoration, on its visible face opposite the cheese. The label 43 has a tab 45 without glue, or in which the glue has been neutralized, or where the adhesive backing paper (usually a silicone paper often called backing by the Anglo-Saxons) has been preserved. . The tongue 45 is free with respect to the sheet 41. It constitutes a gripping member (see Figure 3) that the user can grasp between two fingers. It can adopt a position inclined relative to the sheet 41, so that the user can easily exert a force tending to take off the lid of the cheese.
Par ailleurs, la feuille d'emballage 3 porte le long du bord périphérique 39 une pluralité de languettes de préhension 47 (Figure 1 ), solidaires du bord périphérique et faisant saillie par rapport à ce bord périphérique. Furthermore, the wrapping sheet 3 carries along the peripheral edge 39 a plurality of gripping tabs 47 (Figure 1), integral with the peripheral edge and projecting from the peripheral edge.
Les languettes 47 sont conformées de manière à pouvoir être saisies par l'utilisateur, entre deux doigts, de manière à déployer la feuille d'emballage. The tabs 47 are shaped so that they can be grasped by the user between two fingers so as to deploy the packaging sheet.
Dans l'exemple de réalisation des figures 1 et 2, le bord périphérique 39 de la feuille porte quatre languettes 47 placées à 90° les unes des autres. In the embodiment of Figures 1 and 2, the peripheral edge 39 of the sheet carries four tabs 47 placed at 90 ° to each other.
Dans la variante de réalisation représentée sur les Figures 1 , 2, 1 1 et 12, l'étiquette 43 a une partie principale en forme de demi-lune, la zone 45 formant languette étant solidaire du bord rectiligne de la demi-lune. Elle est raccordée à la partie principale de l'étiquette 43 par une ligne formant une charnière. Dans la variante de réalisation de la Figure 3, l'étiquette 43 a une partie principale 48 ayant une forme générale de disque. La languette 45 se rattache à une zone centrale 49 de ladite partie principale 48. Elle s'étend sensiblement radialement à partir de cette zone centrale 49. Elle s'étend sur un peu plus de la moitié du rayon de la partie principale, et est prolongée par une échancrure 51 découpée dans le bord de la partie principale. La languette 45 est séparée de la partie principale 48 par une ligne de découpe ou d'affaiblissement 53. La ligne 53 ne s'étend pas dans la zone centrale 49, de telle sorte que ladite zone 49 joue le rôle de charnière d'articulation de la languette 45 à la partie principale 48. In the variant embodiment shown in FIGS. 1, 2, 1 1 and 12, the label 43 has a main half-moon-shaped part, the tongue-forming zone 45 being integral with the rectilinear edge of the half-moon. It is connected to the main part of the label 43 by a line forming a hinge. In the embodiment of Figure 3, the label 43 has a main portion 48 having a general disc shape. The tongue 45 is attached to a central zone 49 of said main portion 48. It extends substantially radially from this central zone 49. It extends over a little more than half of the radius of the main portion, and is extended by a notch 51 cut in the edge of the main part. The tongue 45 is separated from the main portion 48 by a cutting or weakening line 53. The line 53 does not extend into the central zone 49, so that said zone 49 acts as a hinge hinge from the tongue 45 to the main part 48.
En variante, l'étiquette est rectangulaire. La languette est solidaire d'un des bords droits de l'étiquette. Alternatively, the label is rectangular. The tongue is attached to one of the right edges of the label.
La Figure 4 illustre un opercule portant un organe de préhension d'un type différent de celui illustré sur les Figures 1 , 2, 3, 1 1 et 12. Seuls les points par lesquels l'opercule de la Figure 4 diffère de celui des Figures 1 et 2 seront détaillés ci-dessous. Les éléments identiques ou assurant la même fonction seront désignés par les mêmes références. FIG. 4 illustrates a lid carrying a gripping member of a type different from that illustrated in FIGS. 1, 2, 3, 1 1 and 12. Only the points by which the lid of FIG. 4 differs from that of FIGS. 1 and 2 will be detailed below. The identical elements or ensuring the same function will be designated by the same references.
Dans l'exemple de réalisation de la Figure 4, l'opercule porte deux organes de préhension 79, venus de matière avec la feuille 41 . Les organes de préhension 79 sont des languettes solidaires du bord libre 37 de l'opercule. Les languettes 79 sont diamétralement opposées par rapport au centre de l'opercule. Avant constitution de l'emballage, les languettes 79 font saillie vers l'extérieur à partir du bord libre 37 de l'opercule. In the exemplary embodiment of FIG. 4, the lid carries two gripping members 79, integral with the sheet 41. The gripping members 79 are tabs secured to the free edge 37 of the cover. The tabs 79 are diametrically opposed relative to the center of the lid. Before constitution of the package, the tabs 79 project outwardly from the free edge 37 of the lid.
Au contraire, après constitution de l'emballage comme décrit ci-dessus, le bord libre 37 de l'opercule est rabattu contre la partie centrale 36 de l'opercule. Les languettes
79, comme illustré sur la Figure 5, sont donc également rabattues contre la partie centrale 36 de l'opercule, et pointe vers le centre de l'opercule, sensiblement radialement, à partir du bord 37. On the contrary, after constitution of the package as described above, the free edge 37 of the lid is folded against the central portion 36 of the lid. The tabs 79, as illustrated in FIG. 5, are thus also folded against the central part 36 of the lid, and points towards the center of the lid, substantially radially, from the edge 37.
Le bord périphérique 39 de la feuille d'emballage est rabattu au-dessus du bord libre 37, contre l'opercule. Les languettes 79 sont ainsi prises entre l'opercule 7 et le bord périphérique 39 de la feuille. L'extrémité des languettes 79 fait saillie au-delà du bord périphérique rabattu 39, dans l'espace libre délimité par ce bord 39. The peripheral edge 39 of the packaging sheet is folded over the free edge 37 against the cover. The tabs 79 are thus taken between the cover 7 and the peripheral edge 39 of the sheet. The end of the tabs 79 protrudes beyond the folded peripheral edge 39, in the free space defined by this edge 39.
L'opercule des Figures 4 et 5 peut comporter une étiquette, collée sur la face visible de cet opercule. The lid of Figures 4 and 5 may comprise a label, glued on the visible face of this lid.
La Figure 6 illustre un opercule équipé d'un autre type d'organe de préhension. Figure 6 illustrates a lid equipped with another type of gripping member.
Seules les différences entre cet opercule et celui des Figures 1 et 2 seront détaillées ci-dessous. Les éléments identiques ou assurant la même fonction seront désignés par les mêmes références. Only the differences between this operculum and that of Figures 1 and 2 will be detailed below. The identical elements or ensuring the same function will be designated by the same references.
Dans l'exemple de réalisation de la Figure 6, l'organe de préhension 81 est un fil ou une bande, rapportée sur l'opercule 7. In the embodiment of Figure 6, the gripping member 81 is a wire or a band, attached to the cover 7.
L'organe de préhension 81 est par exemple un élément connu sous le nom de tircel. Le fil ou la bande 81 sont typiquement en une matière plastique présentant une forte résistance à la traction, par exemple en polyester. L'organe 81 est rigidement fixé à la feuille 41 ou à l'étiquette 43. Il est soudé, ou collé, ou encore fixé par tout autre moyen adapté. Il est agencé de telle sorte qu'une partie de l'organe 81 soit située au centre le l'opercule 7, et soit facilement accessible pour l'utilisateur. The gripping member 81 is for example an element known as a tircel. The wire or the strip 81 are typically made of a plastic material having a high tensile strength, for example polyester. The member 81 is rigidly attached to the sheet 41 or to the label 43. It is welded, or glued, or fixed by any other suitable means. It is arranged such that a portion of the member 81 is located centrally on the cover 7, and is easily accessible to the user.
Dans un autre exemple de réalisation, la feuille 3 est formée d'une feuille d'aluminium renforcée, par exemple d'un complexe aluminium-film plastique-aluminium, d'un complexe aluminium-film plastique, ou encore d'un complexe aluminium-cellophane. In another embodiment, the sheet 3 is formed of a reinforced aluminum foil, for example an aluminum-plastic-aluminum film complex, an aluminum-plastic film complex or an aluminum complex. -cellophane.
Dans un exemple de réalisation, la feuille d'emballage 3 est en un matériau multicouche appelé complexe. La feuille multicouche comporte au moins une première couche en un métal ou un alliage métallique, une seconde couche en un matériau conférant de la rigidité à la feuille, et une couche en une cire pour solidariser les première et seconde couches l'une à l'autre. Le métal est typiquement de l'aluminium. En variante, la feuille peut comporter une couche en un alliage d'aluminium. Selon une autre variante, la couche pourrait être constituée d'étain ou d'un alliage d'étain. In an exemplary embodiment, the packaging sheet 3 is made of a multilayer material called complex. The multilayer sheet has at least a first layer of a metal or a metal alloy, a second layer of a material imparting rigidity to the sheet, and a layer of a wax for securing the first and second layers to one another. other. The metal is typically aluminum. Alternatively, the sheet may comprise a layer of an aluminum alloy. According to another variant, the layer could be made of tin or a tin alloy.
La couche de métal apporte à la feuille d'emballage des propriétés de maintien de la forme, notamment pour les plis, ou une absence d'effet mémoire ou ressort provoquant la réouverture des plis. The metal layer provides the packaging sheet with shape-holding properties, especially for the pleats, or an absence of memory effect or spring causing the reopening of the folds.
La couche de cire permet de réaliser l'assemblage des différentes couches du matériau complexe. L'utilisation de cire permet d'avoir un fluage de cette couche lors du
rainage permettant de réaliser un affaiblissement de la rigidité de la feuille à l'endroit des rainages qui deviendront ensuite des plis. The wax layer makes it possible to assemble the different layers of the complex material. The use of wax makes it possible to have a creep of this layer during the creasing to achieve a weakening of the stiffness of the sheet at the place of the creases which will then become folds.
Par ailleurs, comme expliqué plus loin, la feuille est chauffée au moment du pliage, à une température adaptée, par exemple de 50 'C à l OO'C et avantageusement entre 60 °C et 80 °C, pour permettre le fluage de la cire au moment du pliage. Ainsi, la feuille d'emballage à chaud peut être facilement pliée. A froid, elle présente une rigidité telle que la feuille pliée est autoportante, c'est-à-dire conserve sa forme en l'absence de sollicitation extérieure et ne se déplie pas. Le fluage de la cire pendant le pliage participe au maintien des plis réalisés. Furthermore, as explained below, the sheet is heated at the time of folding, at a suitable temperature, for example from 50 ° C. to 100 ° C. and advantageously between 60 ° C. and 80 ° C., to allow the creep of the wax at the time of folding. Thus, the hot foil can be easily folded. When cold, it has a rigidity such that the folded sheet is self-supporting, that is to say, keeps its shape in the absence of external stress and does not unfold. The creep of the wax during the folding contributes to maintaining the folds made.
La deuxième couche est en un matériau qui confère de la rigidité à la feuille. De préférence, ce matériau a des propriétés de tenue des plis. Il participe ainsi au maintien en forme de la feuille d'emballage pliée, en empêchant un dépliage spontané des plis. The second layer is made of a material that imparts rigidity to the sheet. Preferably, this material has pleat-holding properties. It thus participates in keeping the folded packaging sheet in shape, preventing spontaneous unfolding of the folds.
La deuxième couche est par exemple en papier, ou en une matière plastique chargée en carbonate de calcium, par exemple en un polyéthylène chargé en carbonate de calcium. Par exemple, cette couche comporte entre 20% et 40% de polyéthylène et entre 60% et 80% de craie. En variante préférentielle, cette couche comporte 20% de polyéthylène et 80% de craie. The second layer is for example paper, or a plastic material loaded with calcium carbonate, for example a polyethylene loaded with calcium carbonate. For example, this layer comprises between 20% and 40% of polyethylene and between 60% and 80% of chalk. In a preferred variant, this layer comprises 20% polyethylene and 80% chalk.
Ainsi, après pliage, la feuille ne va pas se déplier spontanément et peut être facilement transférée à l'étape suivante du procédé de production. Thus, after folding, the sheet will not unfold spontaneously and can easily be transferred to the next stage of the production process.
Dans un exemple de réalisation représenté sur la Figure 7, la feuille présente, en partant de l'intérieur de l'ensemble de conditionnement vers l'extérieur, une ou deux couches de laque ou verni (non représentées), une couche d'aluminium 9, une couche de cire 1 1 , une couche de papier 13, une seconde couche de cire 15, une seconde couche d'aluminium 17 et une couche d'encre 19. L'encre 19 est déposée sur la couche d'aluminium 17 et constitue un décor sur le côté visible de la feuille d'emballage. La couche d'aluminium 9 reçoit un verni ou une laque adapté, déposé en une ou deux épaisseurs, en contact direct avec le produit. Ce vernis ou laque pourra optionnellement avoir des qualités permettant un scellage pelable. Les couches 9 à 17 sont déposées à plat les unes sur les autres. Elles sont par exemple complexées les unes sur les autres. Une telle feuille d'emballage est vendue par la société AMCOR ou par la société Richard Laleu, sous le nom de triplex destinée à l'emballage de fromage frais. Cette feuille peut également être assemblée par différents fournisseurs ayant capacité à réaliser un film complexe par assemblage de différents matériaux à l'aide de cire. In an exemplary embodiment shown in FIG. 7, the sheet has, starting from the inside of the packaging unit to the outside, one or two layers of lacquer or varnish (not shown), an aluminum layer 9, a layer of wax 11, a layer of paper 13, a second layer of wax 15, a second layer of aluminum 17 and an ink layer 19. The ink 19 is deposited on the aluminum layer 17 and constitutes a decoration on the visible side of the packaging sheet. The aluminum layer 9 receives a varnish or a suitable lacquer, deposited in one or two thicknesses, in direct contact with the product. This varnish or lacquer may optionally have qualities allowing a peelable seal. The layers 9 to 17 are laid flat on each other. They are for example complexed on each other. Such a packaging sheet is sold by the company AMCOR or the company Richard Laleu, under the name of triplex for packaging fresh cheese. This sheet can also be assembled by different suppliers having the ability to make a complex film by assembling different materials using wax.
En variante, la feuille d'emballage ne comporte pas la couche d'aluminium 17 et la couche de cire 15. La couche de papier 13 est alors positionnée à l'extérieur de l'emballage et reçoit le décor.
Selon une autre variante de réalisation, la feuille 3 comporte, de l'intérieur vers l'extérieur de l'ensemble de conditionnement, une couche ou deux couches de laque ou verni, une couche d'aluminium, une couche de cire, une couche de plastique chargée en carbonate de calcium, et une couche d'encre. La couche de plastique chargée en carbonate de calcium, comme décrit ci-dessus, est par exemple une couche de polyéthylène chargée en carbonate de calcium. Une telle feuille possède des caractéristiques s'approchant de celles du papier, notamment en terme d'aspect, toucher, blancheur, rigidité, tenu des plis et dans une moindre mesure imprimabilité. La réalisation du complexe avec une matière plastique chargée en carbonate de calcium en remplacement du papier permet de donner à ce complexe des qualités de résistance au déchirement. Alternatively, the packaging sheet does not include the aluminum layer 17 and the wax layer 15. The paper layer 13 is then positioned outside the package and receives the decoration. According to another variant embodiment, the sheet 3 comprises, from the inside to the outside of the packaging assembly, a layer or two layers of lacquer or varnish, an aluminum layer, a layer of wax, a layer of of plastic filled with calcium carbonate, and a layer of ink. The plastic layer filled with calcium carbonate, as described above, is for example a polyethylene layer loaded with calcium carbonate. Such a sheet has characteristics approaching those of paper, especially in terms of appearance, feel, whiteness, rigidity, creases and to a lesser extent printability. The realization of the complex with a plastic material loaded with calcium carbonate replacing the paper makes it possible to give this complex qualities of resistance to tearing.
Le procédé de fabrication de l'ensemble de conditionnement va maintenant être détaillé, notamment en référence aux Figures 8 et 9. Le procédé comporte les étapes suivantes : The method of manufacturing the packaging assembly will now be detailed, in particular with reference to FIGS. 8 and 9. The method comprises the following steps:
- découper la feuille d'emballage 3 dans un flan de plus grande taille ; - Cut the packaging sheet 3 into a larger blank;
- de préférence, réaliser les rainages permettant d'affaiblir la feuille au droit des zones que l'on souhaite plier, cette étape pouvant être simultanée à la précédente ; - Preferably, perform creases to weaken the sheet to the right of the areas that it is desired to fold, this step may be simultaneous with the previous;
- plier la feuille d'emballage 3 de manière à former le fond 21 et la paroi latérale 23, avec notamment les soufflets 75 ; - fold the packaging sheet 3 so as to form the bottom 21 and the side wall 23, including the bellows 75;

La feuille d'emballage 3, avant pliage, présente sensiblement une forme circulaire. Après découpe et avant pliage, ou de manière concomitante avec la découpe, des rainages sont ménagés dans la feuille d'emballage 3, le long des lignes de pliage The wrapping sheet 3, before folding, has substantially a circular shape. After cutting and before folding, or concomitantly with the cut, creases are formed in the wrapping sheet 3, along the fold lines
Le pliage est réalisé en faisant passer la feuille dans un outil en forme de manchon cylindrique nommé cheminée de pliage ou chambre de pliage. Si la feuille est du type représenté sur la figure 7, elle est chauffée au moment du pliage, à une température suffisante pour permettre à la cire de fluer sous l'effet du pliage.
Les petits plis permettent d'aboserber facilement le surplus de matière lié au passage d'un disque plat à un cylindre. Ils apportent également une certaine rigidité vertical au cylindre ainsi formé et une esthétique intéressante à l'emballage. Enfin, ils permettent une ouverture totale du cylindre par dépliage de l'ensemble des plis. Folding is accomplished by passing the sheet through a cylindrical sleeve-shaped tool called a bend stack or bending chamber. If the sheet is of the type shown in FIG. 7, it is heated at the time of folding to a temperature sufficient to allow the wax to flow under the effect of folding. The small folds allow to easily aboserber surplus material related to the passage of a flat disc to a cylinder. They also bring a certain vertical rigidity to the cylinder thus formed and an attractive aesthetic to the packaging. Finally, they allow a total opening of the cylinder by unfolding all the folds.
Après passage de la feuille d'emballage dans l'outil de pliage, la feuille présente la forme d'une coupelle de réception (du type représenté sur la Figure 13, relative au seconde mode de pliage). Elle est autoportante et conserve cette forme. Elle est ensuite transférée dans un réceptacle de forme sensiblement cylindrique. Le fromage est déposé dans la feuille pendant que celle-ci est dans le réceptacle. After passing the wrapping sheet in the folding tool, the sheet has the shape of a receiving cup (of the type shown in Figure 13, relating to the second folding mode). It is freestanding and retains this shape. It is then transferred into a receptacle of substantially cylindrical shape. The cheese is deposited in the leaf while it is in the receptacle.
Après remplissage, l'opercule 7 est mis en place sur la surface libre du fromage. After filling, the lid 7 is placed on the free surface of the cheese.
L'étiquette 43 est collée sur la feuille 41 de l'opercule avant découpe de ladite feuille, par exemple dans une bobine d'aluminium. Il est ainsi plus aisé de déposer et de réaliser un marouflage suffisant de l'étiquette sur la feuille. The label 43 is glued to the sheet 41 of the lid before cutting said sheet, for example in an aluminum coil. It is thus easier to deposit and achieve sufficient masking of the label on the sheet.
L'opercule 7 possède initialement la forme illustrée sur la Figure 9. Le bord 37 est dressé autour de la partie centrale 36 et s'étend en regard du bord périphérique 39 de la feuille. The cover 7 initially has the shape shown in Figure 9. The edge 37 is erected around the central portion 36 and extends opposite the peripheral edge 39 of the sheet.
A l'étape de pliage du bord périphérique 39 sur l'opercule, des doigts 65 maintiennent l'opercule 7 plaqué contre le fromage le long d'une ligne 67 de jonction entre le bord dressé 37 et la partie centrale 36. Plusieurs doigts intérieurs 65 sont répartis sur la périphérie de l'opercule. Les doigts 65 présentent chacun une extrémité coudée qui appuie le bord dressé de l'opercule contre la paroi latérale 23 de la feuille. D'autres doigts extérieurs 69 sont répartis autour de l'ensemble de conditionnement. Les doigts 69 viennent appuyer radialement contre le bord périphérique 39 de la feuille d'emballage. Les doigts 69 exercent une contrainte sur le bord périphérique 39 de l'extérieur vers l'intérieur. Sous l'effet de cette contrainte, le bord périphérique 39 et le bord dressé 37 se rabattent sur la partie centrale 36 de l'opercule. Les doigts 65 sont ensuite dégagés par un mouvement radial vers le centre de l'opercule. At the step of folding the peripheral edge 39 on the lid, the fingers 65 hold the lid 7 pressed against the cheese along a line 67 connecting the upright edge 37 and the central portion 36. Several inner fingers 65 are distributed on the periphery of the lid. The fingers 65 each have a bent end that supports the erected edge of the lid against the side wall 23 of the sheet. Other outer fingers 69 are distributed around the packaging assembly. The fingers 69 press radially against the peripheral edge 39 of the packaging sheet. The fingers 69 exert stress on the peripheral edge 39 from the outside to the inside. Under the effect of this constraint, the peripheral edge 39 and the erected edge 37 fall back on the central portion 36 of the lid. The fingers 65 are then released by a radial movement towards the center of the lid.
Les doigts 65 et 69 sont disposés en regard les uns des autres, de telle sorte que la contrainte exercée par les doigts 69 sur le bord périphérique de la feuille d'emballage n'est pas transmise vers le fond dans les autres zones de la paroi latérale et ne provoque pas une déformation de la paroi latérale. Les doigts 65 définissent des zones rigides dans la paroi latérale, autour desquelles le bord périphérique 39 va se plier. En l'absence des doigts 65, les contraintes exercées par les doigts 69 ne provoqueraient pas un pliage net des bords périphériques mais au contraire une déformation générale de la paroi, du fait que le fromage a une texture molle. Le pliage est terminé par une étape de pressage
au moyen d'un piston cylindrique sur le dessus du fromage, pour rabattre complètement le bord 39 sur l'opercule .. The fingers 65 and 69 are arranged facing each other, so that the stress exerted by the fingers 69 on the peripheral edge of the packaging sheet is not transmitted to the bottom in the other areas of the wall side and does not cause deformation of the side wall. The fingers 65 define rigid areas in the side wall, around which the peripheral edge 39 will bend. In the absence of the fingers 65, the stresses exerted by the fingers 69 would not cause a sharp folding of the peripheral edges but on the contrary a general deformation of the wall, because the cheese has a soft texture. Folding is completed by a pressing step by means of a cylindrical piston on the top of the cheese, to completely fold the edge 39 on the lid.
Quand un utilisateur veut consommer le fromage emballé, il procède comme illustré sur les Figures 1 et 2. Il saisit d' abord les languettes 47 solidaires du bord périphérique rabattu contre l'opercule. Il tire les languettes vers le haut, puis les rabat vers le bas de manière à déployer la feuille d'emballage. La traction exercée par l'utilisateur a pour effet de faire pivoter le bord 39 vers l'extérieur par rapport au fond, When a user wants to consume the packaged cheese, he proceeds as illustrated in Figures 1 and 2. He first grasps the tabs 47 integral with the peripheral edge folded against the lid. He pulls the tabs up and folds them downward to unfold the packing sheet. The traction exerted by the user has the effect of pivoting the edge 39 outwards with respect to the bottom,
Puis, comme illustré sur la Figure 2, l'utilisateur saisit la languette 45 de l'opercule, et décolle l'opercule du fromage. Le fromage est alors entièrement accessible, de telle sorte que l'utilisateur peut se servir très facilement. Then, as shown in Figure 2, the user grasps the tab 45 of the lid, and takes off the lid of the cheese. The cheese is then fully accessible, so that the user can use very easily.
Quand l'utilisateur veut remballer le fromage, il replace d'abord l'opercule sur la face supérieure du fromage et reforme la feuille autour du fromage. When the user wants to repack the cheese, it first puts the lid on the top of the cheese and reform the sheet around the cheese.
Il est à noter que les languettes de préhension 47 formées sur le bord périphérique de la feuille permettent à l'utilisateur de déployer la feuille sans se salir les mains et sans que les doigts viennent en contact avec le fromage. Ces languettes sont en effet décalées vers le centre de l'opercule, dans une zone qui ne risque pas de comporter des particules de fromage. De même, l'utilisateur n'est pas obliger d'agripper le bord de l'opercule pour soulever celui-ci et le retirer. Il saisit l'organe de préhension, et tire sur celui-ci. Cet organe est décalé vers le centre de l'opercule, de telle sorte que l'utilisateur ne se salit pas les doigts. L'organe de préhension correspond à la languette 45 sur les Figures 1 et 2, aux languettes 79 sur les Figures 4 et 5, et au fil 81 sur la Figure 6. It should be noted that the gripping tabs 47 formed on the peripheral edge of the sheet allow the user to deploy the sheet without getting dirty hands and without the fingers come into contact with the cheese. These tabs are indeed shifted towards the center of the lid, in an area that is not likely to include cheese particles. Similarly, the user does not have to grip the edge of the lid to lift it and remove it. He grasps the grasping organ, and pulls on it. This body is shifted towards the center of the lid, so that the user does not dirty the fingers. The gripping member corresponds to the tongue 45 in FIGS. 1 and 2, to the tongues 79 in FIGS. 4 and 5, and to the wire 81 in FIG. 6.
Un second type d'emballage va maintenant être décrit, en référence aux Figures 10 à 13. Seuls les points par lesquels ce second emballage diffère de l'emballage des Figures 1 et 2 seront décrits ci-dessous. A second type of package will now be described with reference to Figures 10 to 13. Only the points by which this second package differs from the package of Figures 1 and 2 will be described below.
Les éléments identiques ou assurant les mêmes fonctions seront désignés par les mêmes références. Identical elements or performing the same functions will be designated by the same references.
Dans l'emballage des Figures 10 à 13, la feuille d'emballage n'est pas pliée de manière à ce que la paroi latérale comporte une multitudes de soufflets. In the package of Figures 10 to 13, the packaging sheet is not folded so that the side wall has a plurality of bellows.
Au contraire, comme visible sur la Figure 13, la feuille est pliée de telle sorte que la paroi latérale 23 comporte entre trois et huit pans circonférentiels, référencés 25 et un même nombre de soufflets 27 raccordant les pans les uns aux autres, Les pans 25 sont de préférence régulièrement espacés les uns des autres le long du pourtour de la paroi. On the contrary, as can be seen in FIG. 13, the sheet is folded so that the side wall 23 has between three and eight circumferential faces, referenced 25 and the same number of bellows 27 connecting the panels to each other. are preferably regularly spaced from each other along the periphery of the wall.
Chaque soufflet 27 comporte une zone centrale 29 sensiblement circonférentielle, et deux zones latérales 31 chacune raccordées pas des plis à la zone centrale 29 et à un des pans 25. Par exemple, les zones centrales 29 s'étendent vers l'intérieur de l'emballage par rapport aux pans 25 (Figure 13). Dans une variante non représentée, les
zones centrales 29 sont situées vers l'extérieur de l'emballage par rapport aux pans 25. Chacun des pans 25 et chacune des zones centrales 29 est directement raccordé au fond 21 par une ligne de pliage, référencée respectivement 33 et 35. Les pans 25 et les zones centrales 29 s'étendent sensiblement sur toute la hauteur de la paroi latérale 23. Les lignes de pliage 33 et 35 se raccordent les unes aux autres de manière continue et définissent le bord périphérique du fond 21 . Elles alternent le long de ce bord périphérique. Each bellows 27 comprises a substantially circumferential central zone 29, and two lateral zones 31 each not connected with folds to the central zone 29 and to one of the panels 25. For example, the central zones 29 extend towards the inside of the packaging relative to the panels 25 (Figure 13). In a variant not shown, the Central zones 29 are located towards the outside of the package with respect to the panels 25. Each of the panels 25 and each of the central zones 29 is directly connected to the bottom 21 by a fold line, referenced 33 and 35, respectively. and the central zones 29 extend substantially the full height of the side wall 23. The fold lines 33 and 35 connect to each other continuously and define the peripheral edge of the bottom 21. They alternate along this peripheral edge.
Dans l'exemple de réalisation illustré, les zones centrales 29 ont une forme générale rectangulaire, les pans 25 ayant une forme générale trapézoïdale et les zones latérales une forme générale triangulaire. Le fond 21 a une forme circulaire ou polygonale. In the exemplary embodiment illustrated, the central zones 29 have a generally rectangular shape, the panels 25 having a generally trapezoidal shape and the lateral zones a generally triangular shape. The bottom 21 has a circular or polygonal shape.
Chaque zone latérale 31 est agencée avec une pointe orientée vers le fond, ladite pointe se terminant à la jonction entre les lignes de pliage 33 et 35 respectives du pan 25 et de la zone centrale 29 que ladite zone latérale 31 raccorde l'un à l'autre. Each lateral zone 31 is arranged with a tip oriented towards the bottom, said tip terminating at the junction between the respective fold lines 33 and 35 of the pan 25 and the central zone 29 that said lateral zone 31 connects one to the other. 'other.
De préférence, la paroi latérale comporte entre trois et cinq pans circonférentiels, et encore de préférence quatre pans circonférentiels. Preferably, the side wall comprises between three and five circumferential sides, and still preferably four circumferential panels.
Par exemple, les languettes 47 sont placées, suivant la circonférence de la paroi 23, en regard des pans 25. Par exemple, la feuille comporte une languette 47 pour chaque pan 25, comme représenté sur la Figure 13. Dans une variante non représentée, les languettes de préhension 47 sont placées en regard des soufflets, et plus précisément des zones centrales 29. For example, the tongues 47 are placed, following the circumference of the wall 23, facing the panels 25. For example, the sheet comprises a tongue 47 for each panel 25, as shown in FIG. 13. In a variant not shown, the gripping tabs 47 are placed opposite the bellows, and more precisely the central zones 29.
La feuille d'emballage, après découpe, et avant pliage, a une forme générale octogonale délimitée par huit côtés. Quatre des côtés portent les languettes de préhension 47. Les languettes 47 sont placées radialement dans le prolongement extérieur des zones de la feuille destinée à former les pans circonférentiels 25. The packaging sheet, after cutting, and before folding, has a general octagonal shape delimited by eight sides. Four of the sides bear the gripping tabs 47. The tabs 47 are placed radially in the outer extension of the areas of the sheet intended to form the circumferential flaps 25.
Elle est réalisée dans le même matériau que la feuille de l'emballage des Figures It is made of the same material as the sheet of the packaging of Figures
1 et 2. 1 and 2.
Le pliage est réalisé en faisant passer la feuille dans une chambre de pliage. La paroi périphérique du manchon est constituée de plusieurs doigts indépendants les uns des autres. Les doigts sont raccordés par une première extrémité à un socle, et sont libres à leur seconde extrémité. Chacun des doigts est destiné à former soit l'un des pans 25, soit l'une des zones centrales 29. Dans le cas de la feuille de la Figure 13, le manchon comporte quatre doigts s'inscrivant dans une enveloppe sensiblement cylindrique, destinés à former les pans 25. Il comporte également quatre doigts s'évasant vers l'extérieur de ladite forme cylindrique, destinés à former les zones centrales 29. Folding is accomplished by passing the sheet through a bending chamber. The peripheral wall of the sleeve consists of several fingers independent of each other. The fingers are connected at one end to a base and are free at their second end. Each of the fingers is intended to form either one of the panels 25 or one of the central zones 29. In the case of the sheet of FIG. 13, the sleeve comprises four fingers forming a substantially cylindrical envelope intended to 25. It also comprises four fingers flaring outwardly from said cylindrical shape, intended to form the central zones 29.
Le type de pliage illustré sur les Figures 10 à 13 est particulièrement avantageux. The type of folding illustrated in Figures 10 to 13 is particularly advantageous.
Quand l'utilisateur veut déplier la feuille d'emballage, il saisit d' abord les languettes 47
solidaires du bord périphérique rabattu contre l'opercule. Il tire les languettes vers le haut, puis les rabat vers le bas de manière à déployer la feuille d'emballage. La traction exercée par l'utilisateur a pour effet de faire pivoter les pans 25 vers l'extérieur par rapport au fond, ce mouvement se transmettant aux autres pans par l'intermédiaire des soufflets. II est ainsi très facile de déployer entièrement la feuille d'emballage, en ne sollicitant par exemple que deux des pans de la paroi périphérique. Le mouvement est propagé aux autres pans par les soufflets. Le repliage de la feuille est également facilité, pour les mêmes raisons.
When the user wants to unfold the wrapping sheet, he first grabs the tabs 47 secured to the peripheral edge folded against the lid. He pulls the tabs up and folds them downward to unfold the packing sheet. The traction exerted by the user has the effect of pivoting the panels 25 outwards with respect to the bottom, this movement being transmitted to the other panels by means of the bellows. It is thus very easy to fully deploy the packaging sheet, for example by only requesting two of the sides of the peripheral wall. The movement is spread to other parts by the bellows. The folding of the sheet is also facilitated for the same reasons.
