Before shaping the first sheet (4) by folding, the sheet (4) is heated at selected areas (5) so as to carry out thermoforming during the folding operation.

Description

La présente invention est relative au conditionnement d'un produit pâteux tel qu'un fromage fondu ou un fromage frais fondu ou un fromage frais dans un emballage de conditionnement étanche à ouverture facile constitué de deux feuilles, une première feuille constituant un godet comportant un fond et des faces latérales, et une deuxième feuille constituant un couvercle scellé de façon étanche aux rebords du godet.The present invention relates to the packaging of a pasty product such as a processed cheese or a fresh cream cheese or a fresh cheese in an easy opening sealed packaging package consisting of two sheets, a first sheet constituting a cup having a bottom and side faces, and a second sheet constituting a lid sealingly sealed to the edges of the bucket.

On connaît des emballages de portions de produit pâteux, tel qu'un fromage fondu ou un fromage frais fondu, constitués de feuilles conformées de façon à constituer une coquille et fermées par un couvercle, les feuilles étant scellées de façon à assurer une fermeture étanche. De tels emballages comportent en général un ruban permettant une ouverture facile. Ils sont en général en aluminium et permettent de constituer des portions rectangulaires ou des portions triangulaires.Packaging of portions of pasty product, such as a processed cheese or a melted fresh cheese, consisting of sheets shaped so as to form a shell and closed by a lid, the sheets being sealed so as to ensure a tight closure, are known. Such packages generally include a ribbon for easy opening. They are generally made of aluminum and make it possible to form rectangular portions or triangular portions.

Pour des raisons telles que des raisons d'économie d'énergie, il est avantageux de pouvoir remplacer l'aluminium par des matériaux moins consommateurs d'énergie comme par exemple les matières plastiques tel que le polypropylène. Pour cela, on a proposé de réaliser des emballages de conditionnement de produit pâteux en matière plastique qui nécessitent l'utilisation d'un équipement adapté pour remédier aux inconvénients de ces matériaux qui ne gardent pas la mémoire des pliages qu'on leur a fait subir. C'est le cas notamment du brevet EP 08 03 439 dans lequel on a décrit un procédé et une installation pour réaliser un emballage de conditionnement de matériaux pâteux à partir de trois feuilles de matière plastique qui sont mises en forme et assemblées à l'aide d'installations comportant des outillages de pliage chauffés afin de réaliser un pliage à chaud. Cette technique présente des inconvénients notamment parce qu'elle nécessite soit la mise en place d'équipement spécifiques conduisant des investissements coûteux soit la réalisation de modifications importantes sur les machines existantes conçues pour le matériau tel que l'aluminium. De plus, ce procédé ne permet le chauffage que d'une face externe du godet et non de la laque de scellage qui peut être disposée sur la face interne de celui-ci, ce qui complique les opérations de scellage de l'emballage.For reasons such as energy saving reasons, it is advantageous to be able to replace aluminum with less energy consuming materials such as plastics such as polypropylene. For this, it has been proposed to produce pasty plastic packaging packaging that requires the use of suitable equipment to overcome the disadvantages of these materials that do not keep the memory of the folds they have been subjected to . This is the case of the patent EP 08 03 439 in which a process and an installation for producing a package for packaging pasty materials from three plastic sheets which are shaped and assembled by means of installations having heated bending tools in order to realize hot folding. This technique has disadvantages in particular because it requires either the establishment of specific equipment leading expensive investments or making significant changes to existing machines designed for the material such as aluminum. In addition, this method allows heating only an outer face of the bucket and not the sealing lacquer that can be disposed on the inner face thereof, which complicates the sealing operations of the package.

Le document WO-A-2006/075234 décrit un procédé selon le préambule de la revendication 1.The document WO-2006/075234 discloses a method according to the preamble of claim 1.

Le but de la présente invention est de remédier à ces inconvénients en proposant un procédé qui permet de fabriquer des emballages de conditionnement de produits pâteux, tel qu'un fromage fondu ou un fromage frais fondu ou un fromage frais, à partir de feuilles en matière plastique et qui nécessite peu de modifications des installations de conditionnements connues.The object of the present invention is to remedy these drawbacks by proposing a method which makes it possible to manufacture packagings of pasty products, such as a processed cheese or a fresh cheese or a fresh cheese, from sheets of material plastic and which requires little modification of known packaging facilities.

A cet effet, l'invention a pour effet un procédé de conditionnement d'un produit pâteux tel qu'un fromage fondu ou un fromage frais fondu ou un fromage frais dans un emballage de conditionnement étanche à ouverture facile constitué de deux feuilles minces en matière plastique, une première feuille constituant un godet comportant un fond et des faces latérales et une deuxième feuille constituant un couvercle scellé de façon étanche aux rebords du godet, selon lequel :

  • on découpe la première feuille selon un contour approprié ;
  • on conforme la première feuille par pliage pour former un godet dont les faces latérales s'étendent au-delà de la zone de remplissage du godet ;
  • on remplit de produit pâteux la zone de remplissage du godet ;
  • on dispose sur la surface libre du produit pâteux contenu dans le godet la deuxième feuille découpée à des dimensions au moins égales à celles du fond du godet de façon à former un couvercle, et
  • on scelle le couvercle sur les faces latérales.
For this purpose, the invention has the effect of a method for packaging a pasty product such as a processed cheese or a fresh cheese or a fresh cheese cheese in an easy opening sealed packaging package consisting of two thin sheets of material plastic, a first sheet constituting a cup having a bottom and side faces and a second sheet constituting a lid sealingly sealed to the edges of the cup, according to which:
  • the first sheet is cut into an appropriate contour;
  • conforming the first sheet by folding to form a cup whose side faces extend beyond the bucket fill area;
  • the filling zone of the bucket is filled with pasty product;
  • the second cut sheet is placed on the free surface of the pasty product contained in the cup to dimensions at least equal to those of the bottom of the cup so as to form a lid, and
  • the cover is sealed on the side faces.

Avant de conformer la première feuille par pliage, on chauffe la feuille dans des zones choisies pour permettre un thermoformage au cours du pliage.Before forming the first sheet by folding, the sheet is heated in selected areas to allow thermoforming during folding.

Le chauffage de la feuille peut être effectuée par contact avec au moins une plaque chauffante évidée dans les parties à épargner ou par rayonnement infrarouge ou par soufflage d'air chaud.The heating of the sheet may be effected by contact with at least one hot plate recessed in the parts to be saved or by infrared radiation or by blowing hot air.

Avant le formage du godet, on peut fixer sur la première feuille au moins une bande d'ouverture facile.Before forming the bucket, it is possible to fix on the first sheet at least one easy opening strip.

De préférence, la première feuille comporte une laque thermo-scellable sur la face destinée à être située à l'intérieur de l'emballage et elle est découpée de telle sorte que, après formage du godet au moins une première face latérale comporte une patte dont la face interne vient au contact de la face externe d'une deuxième face latérale du godet et on scelle par thermo-scellage la patte sur la deuxième face latérale.Preferably, the first sheet has a heat-sealable lacquer on the face intended to be located inside the package and is cut so that, after forming the bucket at least a first side face has a tab of which the inner face comes into contact with the outer face of a second side face of the bucket and sealed by heat-sealing the tab on the second side face.

Pour former la première feuille par pliage, on peut la saisir à l'aide d'un piston muni de trous d'aspiration, puis la faire passer à travers une cheminée de formage d'un godet comportant à sa base des rouleaux presseurs avec lesquels on peut serrer les faces latérales du godet de façon à former le plis et éventuellement thermo-sceller une patte d'une face latérale du godet contre une autre face latérale du godet.To form the first sheet by folding, it can be grasped with a piston provided with suction holes, then pass through a forming shaft of a bucket having at its base pressure rollers with which the lateral faces of the bucket can be clamped so as to form the folds and possibly thermo-seal a tab of a lateral face of the bucket against another lateral face of the bucket.

De préférence, après formage du godet, on transfert le godet dans une alvéole comportant des trous d'aspiration à sa périphérie, et on plaque les faces latérales du godet contre les faces latérales de l'alvéole par aspiration et on maintient l'aspiration pendant le remplissage du godet.Preferably, after forming the bucket, the bucket is transferred into a cavity having suction holes at its periphery, and the lateral faces of the bucket are pressed against the side faces of the cavity by suction and the suction is maintained for the filling of the bucket.

Pour mettre en place et sceller le couvercle, on peut procéder de la façon suivante :

  • on saisit la deuxième feuille à l'aide d'un piston muni de trous d'aspiration ;
  • à l'aide du piston, on fait passer la deuxième feuille dans une plaque de formage de façon à donner au couvercle une forme concave avec un petit rebord périphérique ;
  • on dépose le couvercle au contact de la face supérieure du produit contenu dans le godet ;
  • on scelle les rebords du couvercle sur les faces latérales du godet par serrage de mâchoires chauffantes extérieures contre le piston ; et
  • on rabat les rebords des parois latérales du godet contre la face supérieure du couvercle et on les scelle par thermo scellage à l'aide d'un tampon chauffant.
To set up and seal the lid, you can proceed as follows:
  • the second sheet is grasped with a piston provided with suction holes;
  • with the aid of the piston, the second sheet is passed through a forming plate so as to give the lid a concave shape with a small peripheral rim;
  • the lid is deposited in contact with the upper face of the product contained in the cup;
  • sealing the edges of the lid on the lateral faces of the bucket by clamping external heating jaws against the piston; and
  • the flanges of the side walls of the cup are folded against the upper face of the lid and sealed by heat sealing with a heating pad.

De préférence, au moins la première feuille est en polypropylène, éventuellement orienté, et comporte sur une de ses faces une couche de laque thermo scellable.Preferably, at least the first sheet is polypropylene, optionally oriented, and has on one of its faces a thermo sealable lacquer layer.

Le procédé peut être mise en oeuvre par une installation qui comprend notamment :

  • un poste de préchauffage avant formage d'une feuille découpée destinée à être formée pour constituer un godet ;
  • un poste de formage d'un godet comprenant un piston de formage et une cheminée de formage ;
  • une alvéole de réception et de transfert d'un godet.
The method can be implemented by an installation which notably comprises:
  • a preheating station before forming a cut sheet to be formed to form a bucket;
  • a bucket forming station comprising a forming piston and a forming chimney;
  • a cell for receiving and transferring a bucket.

De préférence, le piston du poste de formage comprend des moyens de maintien, notamment par aspiration, d'une feuille contre le piston, et la cheminée de formage comporte à sa base des moyens de serrage latérale d'une feuille en cours de formage contre les faces latérales du piston.Preferably, the piston of the forming station comprises means for holding, in particular by suction, a sheet against the piston, and the forming chimney comprises at its base lateral clamping means of a sheet being formed against the lateral faces of the piston.

Les moyens de serrage latéral disposés à la base de la cheminée de formage sont constitués par exemple de galets montés sur des moyens élastiques réglables.The lateral clamping means arranged at the base of the forming chimney consist for example of rollers mounted on adjustable elastic means.

L'alvéole de réception comporte à sa périphérie des moyens d'aspiration adaptés pour plaquer les faces latérales d'un godet contre les faces latérales de l'alvéole.The receiving cell has at its periphery suction means adapted to press the lateral faces of a bucket against the lateral faces of the cell.

L'installation peut comprendre, en outre, un ou plusieurs des postes suivants :

  • déroulage d'une bande en matière plastique et découpage d'une première ou d'une deuxième feuille,
  • pose de bandes d'ouverture facile,
  • remplissage d'un godet ;
  • mise en place d'un couvercle et scellage du couvercle à l'aide de mâchoires chauffantes,
  • pliage et scellage des rebords du godet.
The installation may also include one or more of the following:
  • unwinding a plastic strip and cutting a first or second sheet,
  • easy opening tapes

Pour réaliser un emballage de conditionnement d'un produit pâteux, tel qu'un fromage fondu ou un fromage frais fondu ou un fromage frais, on déroule un rouleau 1 d'une feuille 2 en matière plastique tel que le polypropylène ou le polypropylène orienté dont une des faces est recouverte d'une laque thermo-scellable. Sur cette feuille de matière plastique, on dépose tout d'abord des rubans d'ouverture facile 3 qui sont par exemple en forme de diapason. Une fois que ces rubans d'ouverture facile sont posés, on découpe dans la feuille de matière plastique une première feuille 4 pour lui donner un contour approprié permettant par pliage de former un godet comportant un fond et des faces latérales qui peuvent être assemblées par thermo-scellage.To produce a packaging for packaging a pasty product, such as a processed cheese or a fresh cheese or a fresh cheese, rolls a roll 1 of a sheet 2 made of plastic such as polypropylene or oriented polypropylene of which one of the faces is covered with a thermo-sealable lacquer. On this sheet of plastic material, first of all, easy opening ribbons 3 are deposited, for example in the form of a tuning fork. Once these easy-opening ribbons are set, a first sheet 4 is cut from the plastic sheet to give it an appropriate contour allowing folding to form a bucket having a bottom and side faces that can be assembled by thermo-plastic. -sealing.

Un exemple de découpe pour réaliser un godet de section carrée est représenté à la figure 1. La feuille 4, de forme généralement en croix, est constituée d'une partie centrale 40 destinée à former le fond du godet qui est entourée par des volets 41, 42, 43 et 44 destinés à former après pliage autour des lignes de pliage 45, 46, 47 et 48 pour former les faces latérales du godet. Afin de faciliter le pliage ultérieur, les lignes de pliage sont pré-marquées lors de la découpe en utilisant des lames adaptées à l'aide desquelles on exerce une pression sur la feuille.An example of cutting to make a cup square section is shown in the figure 1 . The sheet 4, generally cross-shaped, consists of a central portion 40 intended to form the bottom of the cup which is surrounded by flaps 41, 42, 43 and 44 intended to form after folding around the fold lines 45, 46, 47 and 48 to form the side faces of the bucket. In order to To facilitate the subsequent folding, the fold lines are pre-marked during cutting by using adapted blades by means of which pressure is exerted on the sheet.

Dans les coins 49 qui sont situés entre deux volets adjacents, par exemple entre le volet 44 et le volet 41, la feuille est découpée de façon à former deux pattes 50 et 51 séparées par une ligne de pliage diagonale 52. La patte 50 est adjacente au volet 41 et la patte 51 est adjacente au volet 44. Le découpage est adapté pour que la patte 50 et la patte 51 soient de taille différente, en particulier pour que la pattes 51 soit de dimension supérieure à la patte 50, de telle sorte que, lorsque les volets 41 et 44 sont repliés vers le haut pour former les faces latérales du godet, la patte 51 vient recouvrir la patte 50 et s'étend au delà de la patte 50 de façon à ce que sa zone intérieure 53 puisse venir au contact de la face externe du volet 41. Ainsi, la feuille de matière plastique étant recouverte de laque thermo-scellable sur sa face intérieure, la partie 53 de la patte 51 pourra être collée par thermo-scellage sur la face extérieure du volet 41.In the corners 49 which are located between two adjacent flaps, for example between the flap 44 and the flap 41, the sheet is cut so as to form two lugs 50 and 51 separated by a diagonal fold line 52. The lug 50 is adjacent at the flap 41 and the tab 51 is adjacent to the flap 44. The cutting is adapted so that the tab 50 and the tab 51 are of different size, in particular for the tabs 51 to be larger than the tab 50, so that that when the flaps 41 and 44 are folded upwards to form the side faces of the bucket, the tab 51 comes to cover the tab 50 and extends beyond the tab 50 so that its inner zone 53 can come in contact with the outer face of the flap 41. Thus, the plastic sheet being covered with thermo-sealable lacquer on its inner face, the portion 53 of the lug 51 may be glued by heat-sealing on the outer face of the flap 41 .

Naturellement, les quatre coins de la feuille sont découpés de la même façon, afin d'assembler par thermo-scellage chacun des rebords du godet.Naturally, the four corners of the sheet are cut in the same way, in order to thermally seal each of the edges of the bucket.

Cette opération de découpage qui a été repérée 01 à la figure 4 est suivie par une deuxième opération 02 de préchauffage de la première feuille de matière plastique 4 de façon à créer des zones de chauffage 5 qui recouvrent les lignes de pliage selon lesquelles le pliage sera effectué lors de l'opération de pliage 03. Les zones de chauffage, représentées de façon plus détaillée à la figure 3, sont en forme de treillis et recouvrent les lignes de pliage 45, 46, 47 et 48 et laissent libre une zone centrale 55 et des zones médianes dans les volets latéraux 56, 57, 58, 59. Ces zones non chauffées sont nécessaires pour assurer une certaine rigidité de la feuille qui permettra sa manipulation ultérieurement.This cutting operation which was spotted 01 at the figure 4 is followed by a second operation 02 of preheating the first plastic sheet 4 so as to create heating zones 5 which cover the fold lines according to which the folding will be performed during the folding operation 03. The zones of heating, shown in more detail in the figure 3 , are in the form of lattices and cover the fold lines 45, 46, 47 and 48 and leave free a central zone 55 and median zones in the lateral flaps 56, 57, 58, 59. These unheated zones are necessary to ensure a certain rigidity of the sheet that will allow its subsequent handling.

Le chauffage peut être effectué par différents moyens, par exemple en serrant la feuille entre deux patins chauffants ayant des formes adaptées pour effectuer un chauffage selon les zones de chauffage qui ont été prédéterminées. Le chauffage peut également être effectué par des moyens de chauffage par infrarouge ou par soufflage d'air chaud.Heating may be effected by various means, for example by clamping the sheet between two heating pads having shapes adapted to effect heating according to the predetermined heating zones. The heating can also be carried out by infrared heating means or by blowing hot air.

L'homme du métier sait réaliser de tels moyens de chauffage.The skilled person knows how to achieve such heating means.

Après réalisation du chauffage, la première feuille est saisie à l'aide d'un piston 6 qui comporte des canaux internes 61 qui débouchent par des ouvertures 63 sur la face inférieure 62 et qui permettent de maintenir par aspiration la première feuille 4. La face inférieure 62 du piston 6 a une dimension qui est sensiblement égale à la dimension du fond du godet qui doit être formé. A l'aide de ce piston 6, la première feuille 4 est poussée à travers une cheminée de formage 7 dont au moins deux bords inférieurs opposés comportent des galets presseurs 71 qui peuvent exercer un effort latéral de façon à pouvoir serrer la feuille contre les parois du piston de formage. Ces galets presseurs sont montés sur des moyens à ressorts, tels que des ressorts à boudins ou des lames à ressorts réglables 72 qui permettent de régler la pression exercée par les ressorts sur la feuille 4. Cette cheminée de formage 7 débouche sur un plateau comportant une alvéole 9 dont la paroi latérale 90 comporte des trous d'aspiration 91 qui permettent de plaquer les faces latérales d'un godet contre ces parois. Cette alvéole est fermée à sa partie inférieure par un piston éjecteur 92.After completion of the heating, the first sheet is gripped with a piston 6 which has internal channels 61 which open through openings 63 on the lower face 62 and which allow to maintain by suction the first sheet 4. The face bottom 62 of the piston 6 has a dimension which is substantially equal to the dimension of the bottom of the bucket to be formed. With the aid of this piston 6, the first sheet 4 is pushed through a forming chimney 7, at least two opposite lower edges of which have pressure rollers 71 which can exert a lateral force so as to be able to clamp the sheet against the walls of the forming piston. These pressure rollers are mounted on spring means, such as coil springs or blades with adjustable springs 72 which adjust the pressure exerted by the springs on the sheet 4. This forming chimney 7 opens on a plate having a cell 9 whose side wall 90 has suction holes 91 which allow to press the side faces of a bucket against these walls. This cell is closed at its bottom by an ejector piston 92.

A l'aide de ces dispositifs et lors de l'opération de mise en forme 3, on fabrique par pliage un godet 8 comportant des faces latérales 81 qui sont constituées par les quatre volets latéraux de la feuille 4. Ces bords latéraux comportent des pattes 82 qui sont scellées contre des montants latéraux 81. Ces pattes latérales 82 scellées correspondent aux pattes 53 qui ont été préparées sur la première feuille qui avait été découpée. Les pattes 82 sont scellées par thermo-scellage en profitant de la chaleur qui résulte du chauffage préalable fait au cours de l'opération de préchauffage 02.With the aid of these devices and during the shaping operation 3, a cup 8 is made by folding comprising lateral faces 81 which are constituted by the four lateral flaps of the sheet 4. These lateral edges comprise legs 82 which are sealed against lateral uprights 81. These sealed side tabs 82 correspond to tabs 53 which have been prepared on the first sheet which had been cut. The tabs 82 are sealed by heat-sealing taking advantage of the heat that results from the pre-heating done during the preheating operation 02.

Le godet 8 est reçu dans l'alvéole 9 puis il est dégagé de la cheminée de formage 7 pour être amené dans un poste de remplissage pour effectuer une opération de remplissage 04 qui consiste à remplir de produits pâteux une zone de remplissage à l'intérieur du godet, de façon à constituer une charge 11, en utilisant par exemple une bouche d'injection 10.The bucket 8 is received in the cell 9 and it is released from the forming chimney 7 to be brought into a filling station to perform a filling operation 04 which consists of filling pasty products with a filling zone inside. of the bucket, so as to constitute a load 11, using for example an injection port 10.

Cette opération de remplissage est bien connue de l'homme du métier.This filling operation is well known to those skilled in the art.

Après remplissage du godet, celui-ci est amené dans un poste de mise en place d'un couvercle 13. Ce couvercle 13 est constitué d'une deuxième feuille de matière plastique dont une des faces est éventuellement recouverte d'une laque thermo-scellable, qui est découpée selon une forme légèrement plus grande que celle du fond du godet. Cette feuille est saisie par un piston 12 comportant des canaux 120 débouchant sur sa face inférieure par des ouvertures 121 qui permettent de maintenir par aspiration la deuxième feuille contre la face inférieure du piston. Le piston fait passer la deuxième feuille à travers une plaque de formage de façon à constituer un couvercle ayant une forme concave comportant un fond de forme rectangulaire correspondant au fond du godet, bordée par un petit rebord périphérique 14, destiné à permettre un scellage dans le godet et dépose le couvercle sur la face supérieure de la charge de produit pâteux contenu dans le godet. Cette opération de pause du couvercle est repérée 05 sur les figures.After filling of the bucket, it is brought into a position of establishment of a cover 13. This cover 13 is made of a second sheet of plastic material, one of whose faces is optionally covered with a heat-sealable lacquer which is cut into a shape slightly larger than that of the bottom of the bucket. This sheet is gripped by a piston 12 having channels 120 opening on its underside through openings 121 which allow to maintain by suction the second sheet against the underside of the piston. The piston passes the second sheet through a forming plate to form a lid having a concave shape having a bottom of rectangular shape corresponding to the bottom of the bucket, bordered by a small peripheral rim 14, intended to allow sealing in the cup and deposits the lid on the upper face of the pasty product load contained in the cup. This pause operation of the lid is marked 05 in the figures.

Après pause du couvercle sur la face supérieure de la pâte contenue dans le godet, le rebord 14 du couvercle 13 est scellé par thermo-scellage contre les bords supérieures 81 A des faces latérales 81 du godet 8. Ce thermo-scellage est réalisé à l'aide de mâchoires chauffantes 15 qui viennent serrer latéralement la partie supérieure 81A du rebord du godet et les rebords 14 du couvercle contre le piston de manutention 12.After pausing the lid on the upper face of the dough contained in the cup, the rim 14 of the lid 13 is sealed by heat-sealing against the upper edges 81 A of the side faces 81 of the cup 8. This heat-sealing is carried out at the using heating jaws 15 which laterally clamp the upper portion 81A of the rim of the bucket and the flanges 14 of the cover against the handling piston 12.

Une fois ce premier scellage réalisé, dans une dernière opération repérée 07, les rebords 81A sont rabattus contre la face supérieure du couvercle 13 à l'aide de patins 16 qui s'étendent latéralement, puis les rebords 81A des faces latérales 81 qui s'étendent au-delà des rebords 14 du couvercle, sont scellés contre la face supérieure du couvercle 13 à l'aide d'un tampon chauffant 17.Once this first sealing is done, in a last operation marked 07, the flanges 81A are folded against the upper face of the cover 13 with pads 16 which extend laterally, then the flanges 81A of the side faces 81 which extend beyond the rims 14 of the lid, are sealed against the upper face of the lid 13 by means of a heating pad 17.

On obtient ainsi une part de produit pâteux tel qu'un fromage fondu ou un fromage frais fondu ou un fromage frais conditionnée dans un emballage 8 comprenant des parois latérales 81 qui comportent des pattes 82 scellées sur les faces latérales 81 et dont les bords 81A sont rabattus et scellés contre le couvercle 13. Sur la face supérieure du couvercle, une extrémité des rubans d'ouverture facile 3 s'étend au-delà des rebords 81A, ce qui permet de le saisir facilement et d'ouvrir facilement l'emballage.This gives a portion of pasty product such as a processed cheese or a fresh cheese or a fresh cheese packaged in a package 8 comprising side walls 81 which have tabs 82 sealed on the side faces 81 and whose edges 81A are folded and sealed against the lid 13. On the upper face of the lid, one end of the easy opening tapes 3 extends beyond the flanges 81A, which allows easy grasping and easy opening of the package.

Le procédé qui vient d'être décrit peut être mis en oeuvre à l'aide d'installations de conditionnement de matières pâteuses tel que les fromages fondus que l'homme du métier sait réaliser. En particulier, les opérations de pause et du scellage du couvercle sont des opérations connues. L'homme du métier sait réaliser des machines qui permettent de fabriquer en série des conditionnements de matières pâteuses en prévoyant une succession de poste adaptés et des transferts de portions en cours de remplissage d'un poste au poste suivant.The process which has just been described can be carried out using packaging facilities for pasty substances such as processed cheeses which the person skilled in the art knows how to produce. In particular, the pause and lid sealing operations are known operations. The person skilled in the art knows how to produce machines that make it possible to mass-produce packages. pastes by providing for a succession of adapted posts and transfers of portions during filling of a post to the next post.

Dans le mode de réalisation décrit, l'emballage comporte des rubans d'ouverture facile, mais des emballages conformes à l'invention peuvent ne pas comporter de tels rubans ou comporter des moyens d'ouverture facile différents.In the embodiment described, the package comprises easy opening ribbons, but packaging according to the invention may not include such ribbons or have different easy opening means.

Enfin, les parts de produit pâteux emballées peuvent avoir toute forme de type polygonale.Finally, the portions of packaged pasty product can have any form of polygonal type.
